     FIELD OF THE INVENTION 
     The present application relates to a field of safety device for a bank, in particular to a safe coffer device which can avoid being opened violently. 
     BACKGROUND OF THE INVENTION 
     Under present technology conditions, a coffer body of a coffer is made from multiple layers of steel plates, which kind of coffer has strong anti-attack ability. However, some regions of the door on which a dial of a combination lock, a cover of the combination lock and a handle are mounted are relatively weak, and are likely to be attacked by criminals. Generally, the criminals may violently attack the coffer from above mentioned weak regions toward inside of the coffer, so as to destroy combination lock mounted on the back side of the door, or the criminals may drill a hole in the door to destroy a position-limiting bolt of the combination lock, or the criminals may drill a hole to the combination lock and apply an inward force through the hole to destroy the combination lock. The above mentioned regions that may be attacked are referred to as “weak regions” of the coffer, and it is easy for a criminal to successfully open the door of the coffer if he/she attacks the coffer from one of the above mentioned “weak regions”. 
     SUMMARY OF THE INVENTION 
     In view of the “weak regions” of the prior coffer, it is provided according to the present application a safe coffer which can effectively avoid being violently and illegally opened from above mentioned “weak regions”. 
     The safe coffer provided according to the present application includes a coffer body, at least one side of the coffer body is provided with a door. The door is provided with a door locking system, and the door locking system includes a movable bolt which can keep the door and the coffer body in a locking state. The door locking system further includes a breakable component which is fixedly provided on an inner side of the door and can control at least one safety pin. The safety pin can keep the movable bolt in the locking state when the breakable component is broken. 
     Preferably, the safety pin is pulled by and connected to the breakable component via a to linear traction component. When the breakable component is broken, the breakable component cannot apply any traction force to the linear traction component, and thus the safety pin can protrude out to keep the movable bolt in the locking state. 
     Further, the safety pin includes: a fixing bracket which is a hollow element and is fixedly mounted on an inner side of the door, a pin member mounted in a cavity of the fixing bracket, and an elastic member provided in a compressed state between the pin member and an inner wall of the cavity of the fixing bracket. An end of the pin member adjacent to a bottom portion of the cavity is pulled by the linear traction component. 
     Preferably, the door locking system further includes a slidable plate which is connected with the movable bolt and can be controlled to slide leftwards or rightwards by an operation component provided outside the coffer. The leftward or rightward sliding of the slidable plate brings the movable bolt to lock or unlock the door and the coffer body. The slidable plate is provided at a side thereof with a groove. The groove corresponds to the safety pin when the movable bolt is in the locking state. 
     Further, the door locking system further includes a combination lock. The safety pin includes a self-locking pin, a pin bracket which can fix the self-locking pin on the inner side of the door, and an elastic member, elasticity of which is towards the groove, provided in a compressed state between the self-locking pin and the pin bracket.

The self-locking pin fixing plate is provided therein with a position-limiting pole hole which corresponds to self-locking pin. When the self-locking pin fixing plate is moved towards an inner side of the coffer, the position-limiting pole can move out of the position-limiting pole hole in the self-locking pin fixing plate, and thus the self-locking pin can enter the corresponding groove in the side of the slidable plate to keep the movable bolt in the locking state. 
     Further, at least one edge of the self-locking pin fixing plate is formed into a bend edge which is bent towards the breakable component and hooks on the breakable component. 
     Preferably, the safety pin includes a self-locking pin, a pin bracket which can fix the to self-locking pin on the inner side of the door, and an elastic member, elasticity of which is towards the groove, provided in a compressed state between the self-locking pin and the pin bracket. The self-locking pin is provided thereon with a position-limiting pole for stopping the elastic member, and an end of the self-locking pin away from the position-limiting pole is hung on the breakable component via a retaining bracket. When the breakable component is broken, the retaining bracket falls off, thus the self-locking pin enters the corresponding groove in the side of the slidable plate to keep the movable bolt in the locking state. 
     Preferably, the breakable component is a tempered glass plate fixedly provided on the inner side of the door. 
     Further, the door is further fixedly provided on the inner side thereof with a component fixing plate, and the tempered glass plate is provided between the door of the coffer and the component fixing plate. 
     In addition, it is further provided according to the present application a self-service terminal provided with the safe coffer mentioned above. 
     Compared with the prior art, the present application has the following advantageous effects: 
     1. the safe coffer according to the present application can effectively prevent the coffer from being attacked from the combination lock; 
     2. the safe coffer according to the present application can effectively prevent the coffer from being attacked by drilling from the door to the inner side of the coffer, and can enhance safety of the coffer.

     DETAILED DESCRIPTION 
     Hereinafter, a safe coffer which can effectively avoid being violently and illegally opened from above mentioned “weak regions” according to the present application will be described in detail in conjunction with the figures. 
     Referring to  FIGS. 1 and 2 ,  FIG. 1  is a using state view of a coffer door safety device according to the present application. The safe coffer  1  includes a coffer body  10  provided at a side thereof with a door  11 . The door  11  is pivotally connected at an edge thereof to an edge of the coffer body, and is provided with a door locking system  12 . The door locking system  12  includes a movable bolt  121  which can keep the door  11  and the coffer body  10  in a locking state. The door locking system  12  further includes a tempered glass plate  122  which is fixedly provided on an inner side of the door  11 . The tempered glass plate  122  controls a safety pin  123  which can keep the bolt  121  in a locking state if the tempered glass plate  122  is broken. The tempered glass plate  122  provided according to the present embodiment may also employ other available materials which have a certain rigidity and is easily to be broken when suffering from violent attack, for example, ceramic and other brittle materials. 
     The movable bolt  121  is mounted on the inner side of the door  11  and can protrude in a direction away from a pivot of the door. The coffer body  10  is provided at a position of an inner wall thereof corresponding to the movable bolt  121  with a position-limiting bar  101 . When the coffer  1  is locked, the coffer body  10  is engaged with the door  11 , and the movable bolt  121  can be inserted inside the position-limiting bar  101 . At this time, the door  11  cannot be opened because of a limitation action of the position-limiting bar  101 . 
     In particular, referring to  FIG. 2 ,  FIG. 2  further illustrates the safety pin component in the door locking system  12 . The safety pin  123  includes: a fixing bracket  1231  which is a hollow element and is fixedly mounted on the inner side of the door  11 , and a pin member  1232  which is mounted in a cavity of the fixing bracket. A telescopic spring  1233  is provided in a compressed state between the pin member  1232  and an inner wall of the cavity of the fixing bracket  1231 . An end of the pin member  1232  adjacent to a bottom portion of the cavity is pulled by and connected to the tempered glass plate  122  via a wire rope  1234 . The pin member  1232  can compress the spring  1233  and retract into the cavity of the fixing bracket  1231  under a traction force of the wire rope  1234 . Referring to  FIG. 3 , if the tempered glass plate  122  is broken, no traction force is applied to the wire rope  1234 , and thus the wire rope  1234  cannot apply any traction force to the pin member  1232 . In this case, the pin member  1232  can protrude out of the cavity of the fixing bracket  1231  under a restoring force of the spring  1233 . Since the protruded pin member  1232  is located in the opening path of the movable bolt  121 , the protruded pin member  1232  can effectively keep the movable bolt  121  in the locking state. 
     It is to be noted that, in order that the coffer is more safe and reliable, the door locking system  12  may be provided with a plurality of groups of safety pins  123 . As shown in  FIG. 2 , the door locking system  12  may be provided at an upper portion and at a lower portion thereof respectively with one safety pin, such that the movable bolt  121  can be blocked uniformly. 
     Referring to  FIGS. 1 and 4 ,  FIG. 4  shows a safe coffer according to another embodiment of the present application. In the safe coffer, the door locking system  12  includes a movable bolt  121  which can keep the door  11  and the coffer body  10  in a locking state. The movable bolt  121  is connected with a slidable plate  1211 . The slidable plate  1211  can be controlled to slide leftwards or rightwards through a small bolt  13  operated by an operation component (not shown in the figure) provided outside the coffer. The leftward or rightward sliding of the slidable plate  1211  may bring the movable bolt  121  to lock or unlock the door  11  and the coffer body  10 . The slidable plate  1211  is provided at a side thereof with a groove  12111  which corresponds to the position of a safety pin  124  when the movable bolt  121  is in a locking state. The door locking system  12  further includes a tempered glass plate  122  fixedly provided on the inner side of the door  11 . The tempered glass plate  122  can control two safety pins  123  and  124 . If the tempered glass plate  122  is broken, safety pins  123  and  124  can keep the movable bolt  121  in the locking state. The tempered glass plate  122  provided according to the present embodiment may also employ other available materials which have a certain rigidity and is easily to be broken when suffering from violent attack, for example, ceramic and other brittle materials. In order to facilitate mounting of the slidable plate  1211  and other components that need to be fixed with respect to the door  11 , the tempered glass plate  122  is additionally provided at a side thereof away from the door  11  with a mounting plate  14 . The slidable plate  1211  is movably connected with the mounting plate  14 , and the safety pin  124  is fixedly mounted on the mounting plate  14 . 
     The movable bolt  121  is mounted on the inner side of the door  11  and can be brought by the slidable plate  1211  to protrude in a direction away from the pivot of the door. The coffer body  10  is provided at a position of the inner wall thereof corresponding to the movable bolt  121  with a position-limiting bar  101 . When the coffer  1  is locked, the coffer body  10  is engaged with the door  11 , and the movable bolt  121  can be inserted inside the position-limiting bar  101 . In this case, the door  11  cannot be opened because of a limitation action of the position-limiting bar  101 . 
     In particular, reference may be made to  FIG. 2 . The safety pin  123  of the door locking system  12  includes: a fixing bracket  1231  which is a hollow element and is fixedly mounted on the inner side of the door  11 , and a pin member  1232  which is mounted in a cavity of the fixing bracket  1231 . A telescopic spring  1233  is provided in a compressed state between the pin member  1232  and an inner wall of the cavity of the fixing bracket  1231 . An end of the pin member  1232  adjacent to a bottom portion of the cavity is pulled by and connected to the tempered glass plate  122  via a wire rope  1234 . The pin member  1232  can compress the spring  1233  and retract into the cavity of the fixing bracket  1231  under a traction force of the wire rope  1234 . If the tempered glass plate  122  is broken, no traction force is applied to the wire rope  1234 , and thus the wire rope  1234  cannot apply any traction force to the pin member  1232 . In this case, the pin member  1232  can protrude out of the cavity of the fixing bracket  1231  under a restoring force of the spring  1233 . Since the protruded pin member  1232  is located in the opening path of the movable bolt  121 , the protruded pin member  1232  can effectively keep the movable bolt  121  in the locking state. 
     Referring to  FIG. 5 , the safety pin  124  of the door locking system  12  includes a self-locking pin  1241  and a pin bracket  1242  which can fix the self-locking pin  1241  on an inner side of the mounting plate  14 .

If the tempered glass plate  122  is broken, the tempered glass plate  122  cannot support the retaining bracket  1245  anymore, and thus the retaining bracket  1245  cannot apply any traction force to the self-locking pin  1241 . In this case, the self-locking pin  1241  can protrude out of the pin bracket under a restoring force of the spring  1243 . The protruded self-locking pin  1241  can enter corresponding groove  12111  in the slidable plate  1211  and thus can effectively keep the movable bolt  121  in the locking state. 
     Referring to  FIGS. 6, 7 and 8 ,  FIGS. 6, 7 and 8  are inner structure schematic views of a door of a safe coffer according to a third embodiment of the present application. In the coffer, the door locking system  12  includes a movable bolt  121  which can keep the door  11  and the coffer body  10  in a locking state. The movable bolt  121  is connected with a slidable plate  1211 . The slidable plate  1211  can be controlled to slide leftwards or rightwards through a small bolt  13  operated by an operation component (not shown in the figure) provided outside the coffer. The leftward or rightward sliding of the slidable plate  1211  may bring the movable bolt  121  to lock or unlock the door  11  and the coffer body  10 . The slidable plate  1211  is provided at a side thereof with grooves  12111  and  12112  in which the safety pins  123  and  124  to are disposed when the movable bolt  121  is in a locking state. The door locking system  12  further includes a tempered glass plate  122  fixedly provided on the inner side of the door  11 . The tempered glass plate  122  can control two safety pins  123  and  124 . When the tempered glass plate  122  is broken, the safety pins  123  and  124  can keep the movable bolt  121  in the locking state. The tempered glass plate  122  provided according to the present embodiment may also employ other available materials which have a certain rigidity and is easily to be broken when suffering from violent attack, for example, ceramic and other brittle materials. In order to facilitate mounting of the slidable plate  1211  and other components that need to be fixed with respect to the door  11 , the tempered glass plate  122  is additionally provided at a side thereof away from the door  11  with a mounting plate  14 . The slidable plate  1211  is movably connected with the mounting plate  14 , and the safety pin  124  is fixedly mounted on the mounting plate  14 . 
     The movable bolt  121  is mounted on the inner side of the door  11  and can be brought by the slidable plate  1211  to protrude in a direction away from the pivot of the door. The coffer body  10  is provided at a position of the inner wall thereof corresponding to the movable bolt  121  with a position-limiting bar  101 . When the coffer  1  is locked, the coffer body  10  is engaged with the door  11 , and the movable bolt  121  can be inserted inside the position-limiting bar  101 . In this case, the door  11  cannot be opened because of a limitation action of the position-limiting bar  101 . 
     In particular, reference may be made to  FIG. 2 . The safety pin  123  of the door locking system  12  includes: a fixing bracket  1231  which is a hollow element and is fixedly mounted on the inner side of the door  11 , and a pin member  1232  which is mounted in a cavity of the fixing bracket  1231 . A telescopic spring  1233  is provided in a compressed state between the pin member  1232  and an inner wall of the cavity of the fixing bracket  1231 . An end of the pin member  1232  adjacent to a bottom portion of the cavity is pulled by and connected to the tempered glass plate  122  via a wire rope  1234 . The pin member  1232  can compress the spring  1233  and retract into the cavity of the fixing bracket  1231  under a traction force of the wire rope  1234 . If the tempered glass plate  122  is broken, no traction force is applied to the wire rope  1234 , and thus the wire rope  1234  cannot apply any traction force to to the pin member  1232 . In this case, the pin member  1232  can protrude out of the cavity of the fixing bracket  1231  under a restoring force of the spring  1233 . Since the protruded pin member  1232  is located in the opening path of the movable bolt  121 , the protruded pin member  1232  can effectively keep the movable bolt  121  in the locking state. 
     In particular, referring to  FIGS. 5, 7 and 8 , the safety pin  124  of the door locking system  12  includes a self-locking pin  1241  and a pin bracket  1242  which can fix the self-locking pin  1241  on an inner side of the mounting plate  14 .
