     FIELD OF THE INVENTION 
     The present invention relates to a financial self-service apparatus, and more particular to a financial self-service apparatus which may prevent a cash inlet/outlet thereof from being damaged by inserted foreign matters and glue. 
     BACKGROUND OF THE INVENTION 
     At present, the financial self-service apparatus are widely used. Independent self-service apparatus may provide 24-hour uninterrupted service, so as to provide many advantages to people&#39;s lives. Unattended automatic teller machines are convenient to depositors. However, it also provides an opportunity for criminals to steal or intercept money from depositors. As the automatic teller machine is widely installed, criminal cases for the automatic teller machine are also increasing year after year. Such kind of crime mainly includes, i) illegally intercepting money from depositors by taking some actions to the cash outlet; and ii) stealing money from depositors by illegally obtaining information and passwords of bank cards of depositors. 
     For the first kind of crime, the financial self-service apparatus needs to be equipped with a cash outlet gate which may prevent foreign matters from being inserted, prevent liquid glues, resist a certain violent damage and avoid from being illegally opened. A current cash outlet gate is generally resisted by a gate stopper in order to prevent from being illegally opened. However, it is inevitable to form a gap between the gate and a base plate when assembling the gate, and thus criminals may move the gate stopper from the gap with a thin rigid sheet, so that the gate may be easily opened. Obviously, it is an important problem of designing the financial self-service apparatus to improve the safety and reliability of the cash outlet gate and prevent the cash outlet gate from being illegally opened. 
     Therefore, it is necessary to provide an anti-inserted foreign matter and anti-liquid glue damaged financial self-service apparatus, which has simplified structure, a low cost and high safety and reliability. 
     SUMMARY OF THE INVENTION 
     The object of the invention is to provide anti-inserted foreign matter and anti-liquid glue damaged financial self-service apparatus. 
     In view of the above object, the present invention provides a financial self-service apparatus having a panel which is provided with a cash inlet/outlet. The financial self-service apparatus further includes a gate configured to open or close the cash inlet/outlet. The edges of the gate engaged with the cash inlet/outlet are provided with polyoxymethylene (POM) plastic convex dots, so that a flow guiding gap is formed between the gate and the panel when the gate closes the cash inlet/outlet. 
     Preferably, the polyoxymethylene (POM) plastic convex dots are distributed uniformly and equidistantly. 
     More preferably, the polyoxymethylene (POM) plastic convex dots are sphere convex dots. 
     The self-locked gate device according to the present invention has the following advantages. 
     The present invention utilizes the characteristic that liquid glues available in the market don&#39;t stick the POM plastic. The edges of the gate engaged with the cash inlet/outlet of the financial self-service apparatus are provided with POM plastic convex dots, thus, the flow guiding gap for liquid glues is formed, and guides liquid glues to flow out. Besides, the convex dots are designed as sphere convex dots, which may minimize the contact area between the gate structure and the panel of the cash inlet/outlet of the financial self-service apparatus, and decrease the destructive degree of glues to the gate device, thereby preventing the financial self-service apparatus from being damaged by glues. In addition, POM plastic convex dots are uniformly distributed. Foreign matters larger than the gap between adjacent convex dots cannot be inserted into the financial self-service apparatus, thereby performing the function of preventing foreign matters from being inserted.

     DETAILED DESCRIPTION 
     Hereinafter, the technical solutions in embodiments of the present invention will be described clearly and completely with reference to drawings of the embodiments of the present invention. It is apparent that the embodiments to be described are merely a portion of embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all of other embodiments made by those skilled in the art without inventive effort fall into the protection scope of the present invention. 
     Referring to  FIGS. 1 to 6 , the preferred gate device of the cash inlet/outlet  1  applied in the financial self-service apparatus includes an integral welded frame  3 , a door  2  and a power transmission mechanism. The door  2  is of a plate shape. A plurality of polyoxymethylene (POM) plastic sphere convex dots  9  are provided at peripheral edges of the front surface of the door  2 , wherein the front surface of the door  2  is engagable with a cash inlet/outlet of the financial self-service apparatus, and the peripheral edges of the door  2  are engagable with the peripheral edges of the cash inlet/outlet. The POM plastic sphere convex dots  9  are arranged and fixed at the peripheral edges of the door plate equidistantly. When the door  2  is in a closed state, the POM plastic anti-sticking sphere convex dots  9  are in contact with the panel of the financial self-service apparatus, and a flow guiding gap is formed between the door  2  and the panel, foreign matters which are larger than the distance between the POM plastic sphere convex dots  9  and the flow guiding gap between the door and the panel cannot be inserted. In addition, since commonly used liquid glues such as  502  and AA do not stick POM plastic and the POM plastic sphere convex dots are in contact with the panel of the financial self-service apparatus, the contact area between the door  2  and the panel of the financial self-service apparatus may be greatly reduced. Thus, referring to  FIG. 3 , when the liquid flows into the financial self-service apparatus through the gap between the panel of the financial self-service apparatus and the door  2 , the liquid may flow through the space between the POM plastic sphere convex dots and the flow guiding gap between the door and the panel, and then flow out via a flow guiding inclined surface  31  (so do the dust and the water). Since remnant glue on the contact surface between the POM plastic anti-sticking sphere convex dots and the panel of the financial self-service apparatus doesn&#39;t stick the POM plastic, the door may be opened by a torque of the door opening electric motor which is slight larger than the normal torque. Therefore, the provision of the POM plastic sphere convex dots may effectively both prevent foreign matters or liquid from filling into the financial self-service apparatus through the gate device by criminals, and prevent the gate device from being damaged with the liquid glues available in the market by criminals, and thus play a safeguard function. 
     Referring to  FIGS. 2 ,  4 ,  5  and  6 , in order to meet the safe requirement of automatically opening the gate and preventing the gate from being illegally opened by an external force, one side of the door  2  is installed to the frame  3  through a first rotation shaft  4  and is rotatable around the first rotation shaft  4 . Specifically, a pair of shaft seats  21  is fixed on the back surface of the door  2 , and the first rotation shaft  4  is fixed to the door  2  through the shaft seats  21 . Two ends of the first rotation shaft  4  are connected to the frame  3  through a pair of bearings  41 . After being installed, the door  2  may be rotated around the axis of the first rotation shaft  4 , so as to open or close the cash inlet/outlet  1  of the financial self-service apparatus. Certainly, the power to rotate the door  2  around the axis of the first rotation shaft  4  comes from the power transmission mechanism which is fixed on the frame  3 . The power transmission mechanism includes a electric motor  5 , a driving gear  51 , a driven gear  52  and a pair of one-way folded connecting rod mechanism. Specifically, the electric motor  5  is fixed on the frame  3 , and drives the driving gear  51  to rotate in a clockwise or a counterclockwise direction. The driven gear  52  is engaged with the driving gear  51 , and is rotated in a reverse direction as the driving gear  51  rotates. The driven gear  52  is installed on a rotation shaft  6  which is installed on the frame  3  through a pair of bearings  61 . The driven gear  52  is fixedly connected with the rotation shaft  6 . When the driven gear  52  is rotated, the rotation shaft  6  is rotated synchronously. The pair of one-way folded connecting rod mechanisms are connected between the rotation shaft  6  and the door  2 , and located symmetrically at two ends of the rotation shaft  6 . Specifically, each of one-way folded connecting rod mechanisms includes a first connecting rod  71  and a second connecting rod  72 . One end of the first connecting rod  71  is connected to the door  2  through a rotation shaft  8 . The rotation shaft  8  is fixed on the back surface of the door  2  through shaft seats  81 . The rotation shaft  8  is disposed to parallel to the first rotation shaft  4 , and located at the other side of the back surface of the door  2  opposite to the rotation shaft  4 . One end of the second connecting rod  72  is hinged with the other end of the first connecting rod  71  through a shaft  73 . Specifically, the end of the second connecting rod  72  adjacent to the first connecting rod  71  is formed into two extending sheets  721 . The rotation shaft  73  fixedly passes through the two extending sheets  721 . The first connecting rod  71  is hold between the two extending sheets  721  and movably provided on the rotation shaft  73 . The other end of the second connecting rod  72  is fixedly connected to the rotation shaft  6 , and is rotated as the rotation shaft  6  rotates. As shown in  FIG. 6 , the second connecting rod  72  and the rotation shaft  6  are designed into a rod embracing structure. When assembling, the end of the second connecting rod  72  may clamp the rotation shaft  6  by adjusting a tightening screw  723 . Such rod embracing design allows the second connecting rod  72  to be stably and fixedly connected to the rotation shaft  6  and be rotated as the rotation shaft  6  rotates, and may ensure that there is no slip between the second connecting rod  72  and the rotation shaft  6 , thereby ensuring that two second connecting rods  72  of the pair of one-way folded connecting rod mechanisms  70  may be synchronously rotated as the rotation shaft  6  rotates. In this embodiment, when being rotated around the axis of the shaft  6 , the two second connecting rods  72  may be effectively maintained in parallel, that is, they are not twisted. 
     When the electric motor  5  rotates in the counterclockwise direction as shown in  FIG. 4 , the driving gear  51  is rotated in the counterclockwise direction, and thus the driven gear  52  is rotated in the clockwise direction. Thus, the rotation shaft  6  and the second connecting rod  72  fixedly connected to the rotation shaft  6  are rotated in the clockwise direction. Since the second connecting rod  72  is hinged with the first connecting rod  71  through the shaft  73 , the first connecting rod  71  is rotated when the second connecting rod  72  rotates in the clockwise direction. Specifically, the end of the first connecting rod  71  hinged with the second connecting rod  72  is raised, and thus the other end thereof connected to the rotation shaft  8  is raised, so as to draw the door  2  to rotate around the axis of the first rotation shaft  4 , thereby opening the cash inlet/outlet  1  of the financial self-service apparatus. As shown in  FIG. 5 , a schematic view of the gate when being in the completely opened state is shown, at this moment, the first connecting rod  71  and the second connecting rod  72  are approximately in parallel, and the second connecting rod  72  cannot drive the first connecting rod  71  to rotate in the clockwise direction, that is, the first connecting rod  71  and the second connecting rod are in folded state. 
     Correspondingly, when the door  2  is to be closed, the electric motor  5  rotates in reverse direction, and drives the driving gear  51  to rotate in the clockwise direction, so that the driven gear  52  is rotated in the counterclockwise direction. Thus, the rotation shaft  6  and the second connecting rod  72  are rotated in the counterclockwise direction. The second connecting rod  72  pushes the first connecting rod  71  to move, and the first connecting rod  71  pushes the door  2  to rotate around the axis of the first rotation shaft  4  in the clockwise direction, thereby closing the door  2 . As shown in  FIG. 2 , a schematic sectional view of the gate when being in the completely closed state is shown, at this moment, the first connecting rod  71  and the second connecting rod  72  are in an approximate straight state. The end of the first connecting rod  71  adjacent to the shaft  73  has an end surface  711 , and the second connecting rod  72  has an end surface  722  cooperated with the end surface  711  of the first connecting rod  71 . At this moment, as shown in  FIG. 4 , the end surface  711  and the end surface  722  butt against with each other, so that the second connecting rod  72  cannot be continuously rotated in the counterclockwise direction, thereby the door  2  being in the closed state. 
     At this moment, if the door is pushed by an external force F, the external force F is transmitted to the second connecting rod  72  through the first connecting rod  71  in a direction of connecting line between the axes of the shaft  8  and the shaft  73 . Since the axis of the shaft  73  is positioned below the connecting line between the axis of the shaft  8  and the axis of the shaft  6 , the second connecting rod  72  would only be rotated around the axis of the shaft  6  in the counterclockwise direction, so that the first connecting rod  71  have to swing around the axis of the shaft  8  in the clockwise direction. However, the door has been in the closed state, and the end surface  711  of the end of the first connecting rod  71  adjacent to the shaft  73  and the end surface  722  of the end of the second connecting rod  72  adjacent to the shaft  73  have been butted against with each other, so the second connecting rod  72  cannot be rotated around the axis of the shaft  6  in the counterclockwise direction, and the first connecting rod  71  cannot swing around the axis of the shaft  8  in the clockwise direction, thereby achieving the self-locked state of the connecting rod mechanisms  70 . Besides, when the external force F is increased, the interaction force between the end surface  711  of the first connecting rod  71  and the end surface  722  of the second connecting rod  72  is also increased, meanwhile, the shearing force exerted to the shaft  73  is also increased, which may effectively prevent the gate device from being illegally opened by the external force F. 
     As can be known from the above description, in order to prevent the gate device from being illegally opened by an external pushing force, it is necessary to ensure that, when being transmitted through the one-way folded connecting rod mechanism, the external force F cannot generate a component force, at the shaft  73 , which may drive the connecting rod  72  to rotate around the shaft  6  in the clockwise direction. According to the principle of the mechanics transmission, in order to achieve the above object, there is a particular position relationship between the shaft  8 , the connecting rod  71 , the shaft  73 , the connecting rod  72  and the shaft  6 , i.e., the shaft  73  cannot be positioned above the connecting line A between the axis of the rotation shaft  8  and the axis of the rotation shaft  6 . That is, the axes of the shaft  8 , the shaft  73  and the shaft  6  should be in the same line, or the shaft  73  should be positioned below the connecting line A between the axes of the rotation shaft  8  and the rotation shaft  6 . If a connecting line B is assumed between the axis of the shaft  73  and the axis of the rotation shaft  6 , a separation angle is formed between the connecting line A and the connecting line B. Thus, since the end surfaces  711 ,  722  abut against with each other, the first connecting rod  71  cannot be rotated around the shaft  73  in the clockwise direction under the external force F, and thus the door  2  cannot be opened because the first connecting rod  71  cannot be rotated in the clockwise direction. If the door  2  is to be opened by rotating the first connecting rod  71  around the shaft  73  in the counterclockwise direction, the weight P of the connecting rod can be overcome only by the power of internal electric motor. That is, the shaft  6  is rotated and drives the second connecting rod  72  to rotate in the clockwise direction, so that the shaft  73  goes across the connecting line A between the shaft  8  and the shaft  6 , and drives the connecting rod  71  to rotate, thereby opening the gate. In the embodiment, the separation angle between the connecting line A and the connecting line B is 5 degree. Of cause, the separation angle may be any appropriate degree according to an actual requirement. 
     In addition, in order to further prevent the gate device from being illegally opened, referring to  FIGS. 1 ,  2 ,  4  and  5 , a torsion spring  75  is provided on the rotation shaft  8 . One end of the torsion spring  75  is fixed in a location groove  712  formed in an upper side surface of the first connecting rod  71 , and the other end of the torsion spring  75  is fixed to the shaft seat  81  of the rotation shaft  8 . The torsion spring  75  provides a force of rotating the first connecting rod  71  around the rotation shaft  8  in the clockwise direction, so that the first connecting rod  71  and the second connecting rod  72  are kept in the locked state when the door  2  is in the closed state. Therefore, the provision of the torsion spring  75  may effectively control the jump of the rotation shaft  73  of the connecting rods  71  and  72  in upward or downward direction caused by the vibrating force from the outer side of the door plate, and prevent self-lock of the one-way folded connecting rod mechanism  70  from failing caused when the jump of the rotation shaft  73  in upward or downward direction goes across the connecting line between the axis of the rotation shaft  74  and the axis of the rotation shaft  6 . In other words, when a person attempts to apply the external force F to rotate the first connecting rod  71  in the counterclockwise direction and open the door  2 , it is also necessary to overcome the torsion force of the torsion spring  75  to raise the shaft  73  such that the first connecting rod  71  is rotated in the counterclockwise direction. Therefore, due to the provision of the torsion spring  75 , it becomes more impossible to illegally open the door  2  by attempting to rotate the first connecting rod  71  in the counterclockwise direction under the external force F. 
     Therefore, the gate device according to the present invention may be self-locked by the one-way folded connecting rod mechanism, and has a function of preventing the gate device from being violently and illegally opened. Besides, the one-way folded connecting rod mechanism has a simplified structure and a low cost. 
     In addition, the preferred embodiment according to the present invention may ideally solve some problems. For example, criminals take means such as filling foreign matters or liquid glues, so that the gate device works abnormally, in order to obtain an opportunity to destroy the gate device to steal the cash in the financial self-service apparatus. 
     While the preferred embodiments of the present invention have been described above, it is not intended to limit the protection scope of the present invention. Therefore, various equivalent variations made by those skilled in the art based on the contents described in the Description and illustrated in drawings of the present invention are deemed to fall into the protection scope of the present invention.
