     Compared with the prior art, the present disclosure provides the following benefits. 
       1 . The structure of the reel locking device of this application is simple and easy to implement. By providing the automatic locking mechanism, automatic locking is realized, facilitating to prevent the free rotation of the synchronization member ( 31 ) and the vertical reel ( 3 ), thus achieving safety control. By providing the manual unlocking slider ( 41 ), it facilitates the manual unlocking of the automatic locking mechanism. Furthermore, the arrangement of the pressing member ( 51 ) facilitates the hindering of the movement of the manual unlocking slider ( 41 ) both when the pressing member ( 51 ) is not pressed and after resetting. That is, when the pressing member ( 51 ) is not pressed and after resetting, it prevents the manual unlocking slider ( 41 ) from changing the working state of the automatic locking mechanism, thus realizing safety control. In order to change the working state of the automatic locking mechanism, first the pressing member ( 51 ) needs to be pressed, before you are able to manually unlock the slider ( 41 ) to reset from the unlocked position or move from the reset position to the unlocked position. In addition, when the manual unlocking slider ( 41 ) is in the reset position, the automatic locking mechanism is in the locked state, so that when the user only presses the pusher ( 51 ) and does not operate the manual unlocking slider ( 41 ), the automatic locking mechanism is still in the locked state, and so it is generally difficult for children to perform the two-step unlocking operation, resulting in real practicability. 
       2 . In this application, the first elastic driving member ( 43 ) of the automatic locking mechanism is arranged to facilitate the driving the movable block ( 42 ) to move towards the synchronization member ( 31 ), thereby realizing the automatic locking of the automatic locking mechanism. Furthermore, the second elastic driving member ( 44 ) is arranged in order that the manual unlocking slider ( 41 ) can be automatically reset when the manual unlocking slider ( 41 ) is in the unlocked position and there is no obstruction, so that the first elastic driving member ( 43 ) drives the movable block ( 42 ) to reset, thus resetting and locking the automatic locking mechanism, resulting in good practicability. 
     3. In this application, by arranging the first color body ( 410 ) and the second color body ( 110 ), the color bodies of different colors would appear when the manual unlocking slider ( 41 ) is in different positions, facilitating the user to know the current working state of the automatic locking mechanism, hence good practicability. 
     4. In this application, the third elastic driving member ( 52 ) of the elastic pressing mechanism is provided to facilitate driving the pressing member ( 51 ) to reset upward. The first interlocking portion ( 411 ) and the second interlocking portion ( 511 ) are arranged so that the when the manual unlocking slider ( 41 ) is in the unlocked position the second interlocking portion ( 511 ) is reset upward to be interlocked or engaged with the first interlocking portion ( 411 ), allowing the manual unlocking slider ( 41 ) to be kept in the unlocked position and unable to be reset. As such, the user can spare his hand to pull and secure the gate mesh ( 2 ), providing real practicality. Further, pressing down the pressing member ( 51 ) can release the engagement between the first interlocking portion ( 411 ) and the second interlocking portion ( 511 ) so that the manual unlocking slider ( 41 ) can be reset. 
     5. According to this application, the structure of the mesh-type gate is simple and easy to implement. The vertical reel ( 3 ) is arranged to facilitate the retracting and unwinding of the gate mesh ( 2 ), and takes up little space after rolling up the gate mesh ( 2 ). By providing the automatic locking mechanism, automatic locking is realized, facilitating to prevent the free rotation of the synchronization member ( 31 ) and the vertical reel ( 3 ), thus achieving safety control. By providing the manual unlocking slider ( 41 ), it facilitates the manual unlocking of the automatic locking mechanism. Furthermore, the arrangement of the pressing member ( 51 ) facilitates the hindering of the movement of the manual unlocking slider ( 41 ) both when the pressing member ( 51 ) is not pressed and after resetting. That is, when the pressing member ( 51 ) is not pressed and after resetting, it prevents the manual unlocking slider ( 41 ) from changing the working state of the automatic locking mechanism, thus realizing safety control. In order to change the working state of the automatic locking mechanism, first the pressing member ( 51 ) needs to be pressed, before you are able to manually unlock the slider ( 41 ) to reset from the unlocked position or move from the reset position to the unlocked position. In addition, when the manual unlocking slider ( 41 ) is in the reset position, the automatic locking mechanism is in the locked state, so that when the user only presses the pusher ( 51 ) and does not operate the manual unlocking slider ( 41 ), the automatic locking mechanism is still in the locked state, and so it is generally difficult for children to perform the two-step unlocking operation, resulting in real practicability. The pull ring ( 21 ) is arranged at the free end of the gate mesh ( 2 ) to facilitate pulling out the gate mesh ( 2 ) and hook it onto the buckle seat ( 6 ) arranged on the other side, thus achieving the gate function.

     DETAILED DESCRIPTION 
     The features of the utility model and other related features will be further described in detail below through some particular embodiments, so as to facilitate the understanding by those skilled in the art. 
     As illustrated in  FIGS.  1  to  10   , there is provided a reel locking device for a mesh type gate, the reel locking device includes a reel seat ( 1 ), which is rotatably connected with a vertical reel ( 3 ) for retracting and unwinding a gate mesh ( 2 ). A synchronization member ( 31 ) is fixedly connected to one end of the vertical reel ( 3 ). The reel seat ( 1 ) is equipped with an automatic locking mechanism for preventing the synchronization member ( 31 ) from rotating freely. The automatic locking mechanism includes a resettable manual unlocking slider ( 41 ). The reel seat ( 1 ) is further installed with an elastic pressing mechanism for obstructing the movement of the manual unlocking slider ( 41 ). The elastic pressing mechanism includes a pressing member ( 51 ) that does not obstruct the movement of the manual unlocking slider ( 41 ) after being pressed, and that hinders the movement of the manual unlocking slider ( 41 ) both when it is not pressed down and after resetting. 
     As mentioned above, the structure of the reel locking device of this application is simple and easy to implement. By providing the automatic locking mechanism, automatic locking is realized, facilitating to prevent the free rotation of the synchronization member ( 31 ) and the vertical reel ( 3 ), thus achieving safety control. By providing the manual unlocking slider ( 41 ), it facilitates the manual unlocking of the automatic locking mechanism. Furthermore, the arrangement of the pressing member ( 51 ) facilitates the hindering of the movement of the manual unlocking slider ( 41 ) both when the pressing member ( 51 ) is not pressed and after resetting. That is, when the pressing member ( 51 ) is not pressed and after resetting, it prevents the manual unlocking slider ( 41 ) from changing the working state of the automatic locking mechanism, thus realizing safety control. In order to change the working state of the automatic locking mechanism, first the pressing member ( 51 ) needs to be pressed, before you are able to manually unlock the slider ( 41 ) to reset from the unlocked position or move from the reset position to the unlocked position. In addition, when the manual unlocking slider ( 41 ) is in the reset position, the automatic locking mechanism is in the locked state, so that when the user only presses the pusher ( 51 ) and does not operate the manual unlocking slider ( 41 ), the automatic locking mechanism is still in the locked state, and so it is generally difficult for children to perform the two-step unlocking operation, resulting in real practicability. 
     As mentioned above, in specific implementations, the reel seat ( 1 ) in this application may be assembled from multiple parts. 
     As illustrated in  FIGS.  5  and  6   , in specific implementations, the automatic locking mechanism may include a movable block ( 42 ) for blocking the synchronization member ( 31 ), a first elastic driving member ( 43 ) for driving the movable block ( 42 ) to move to and engage with the synchronization member ( 31 ), and a second elastic driving member ( 44 ) for driving the manual unlocking slider ( 41 ) to reset, where pushing the manual unlocking slider ( 41 ) in the direction of the movable block ( 42 ) can press the movable block ( 42 ) away from the synchronization member ( 31 ). 
     As mentioned above, in this application, the first elastic driving member ( 43 ) of the automatic locking mechanism is arranged to facilitate the driving the movable block ( 42 ) to move towards the synchronization member ( 31 ), thereby realizing the automatic locking of the automatic locking mechanism. Furthermore, the second elastic driving member ( 44 ) is arranged in order that the manual unlocking slider ( 41 ) can be automatically reset when the manual unlocking slider ( 41 ) is in the unlocked position and there is no obstruction, so that the first elastic driving member ( 43 ) drives the movable block ( 42 ) to reset, thus resetting and locking the automatic locking mechanism, resulting in good practicability. 
     As illustrated in  FIGS.  4 ,  5 , and  9   , in specific implementations, the reel seat ( 1 ) is provided with a transverse groove ( 11 ) in which the manual unlocking slider ( 41 ) and the second elastic driving member ( 44 ) are arranged and a vertical through hole ( 12 ) for the upper end of the pressing member ( 51 ) to appear outward. The manual unlocking slider ( 41 ) is provided with a first color body ( 410 ), and the transverse groove ( 11 ) is provided with a second color body ( 110 ), where the first color body ( 410 ) and the second color body ( 110 ) have different colors. When the manual unlocking slider ( 41 ) is in the reset position, the first color body ( 410 ) appears outward and the second color body ( 110 ) is covered by the manual unlocking slider ( 41 ). Otherwise when the manual unlocking slider ( 41 ) is in the unlocking position, the first color body ( 410 ) is covered by the transverse groove ( 11 ) and the second color body ( 110 ) appears outward. 
     As mentioned above, in this application, by arranging the first color body ( 410 ) and the second color body ( 110 ), the color bodies of different colors would appear when the manual unlocking slider ( 41 ) is in different positions, facilitating the user to know the current working state of the automatic locking mechanism, hence good practicability. 
     As mentioned above, in specific implementations, the synchronization member ( 31 ) may be a gear, and the movable block ( 42 ) is rotatably mounted on the reel seat ( 1 ), and its free end is provided with a clamping tooth portion ( 421 ) for being engaged with the tooth groove of the gear, which is convenient to implement. 
     As mentioned above, in specific implementations, it may also include a winding spring ( 30 ) for driving the vertical reel ( 3 ) to automatically roll up the gate mesh ( 2 ). As illustrated in  FIG.  6   , the teeth of the synchronization member ( 31 ) and/or the teeth of the clamping tooth portion ( 421 ) are such oriented that when the movable block ( 42 ) is elastically blocking the synchronization member ( 31 ), it does not hinder the winding spring ( 30 ) from driving the vertical reel ( 3 ) and the synchronization member ( 31 ) to rotate in the forward direction, but prevents the synchronization member ( 31 ) from rotating in the reverse direction. In this way, in actual use it facilitates hindering the further drawing of the gate mesh ( 2 ) while not hindering the vertical reel ( 3 ) from automatically rolling and tightening the gate mesh ( 2 ) when the automatic locking mechanism is locked, which prevents the other end of the gate mesh ( 2 ) from loosening. 
     As illustrated in  FIGS.  4 ,  5 ,  8 , and  10   , in specific implementations, the elastic pressing mechanism includes a third elastic driving member ( 52 ) for driving the pressing member ( 51 ) to reset upward. The manual unlocking slider ( 41 ) is provided with a first interlocking portion ( 411 ), and the pressing member ( 51 ) is provided with a second interlocking portion ( 511 ) that is able to be interlocked with the first interlocking portion ( 411 ) when the pressing member ( 51 ) is reset upwards so that the manually unlocked slider ( 41 ) can be kept in the unlocked position and cannot be reset. Pressing down the pressing member ( 51 ) can release the interlocking of the first interlocking portion ( 411 ) and the second interlocking portion ( 511 ) so that the manual unlocking slider ( 41 ) can be reset. When the manual unlocking slider ( 41 ) and the pressing member ( 51 ) are each in the reset position, the pressing member ( 51 ) or the second interlocking portion ( 511 ) on it hinders the manual unlocking slider ( 41 ) from moving to the unlocked position. 
     As mentioned above, in this application, the third elastic driving member ( 52 ) of the elastic pressing mechanism is provided to facilitate driving the pressing member ( 51 ) to reset upward. The first interlocking portion ( 411 ) and the second interlocking portion ( 511 ) are arranged so that the when the manual unlocking slider ( 41 ) is in the unlocked position the second interlocking portion ( 511 ) is reset upward to be interlocked or engaged with the first interlocking portion ( 411 ), allowing the manual unlocking slider ( 41 ) to be kept in the unlocked position and unable to be reset. As such, the user can spare his hand to pull and secure the gate mesh ( 2 ), providing real practicality. Further, pressing down the pressing member ( 51 ) can release the engagement between the first interlocking portion ( 411 ) and the second interlocking portion ( 511 ) so that the manual unlocking slider ( 41 ) can be reset.

The vertical reel ( 3 ) is arranged to facilitate the retracting and unwinding of the gate mesh ( 2 ), and takes up little space after rolling up the gate mesh ( 2 ). By providing the automatic locking mechanism, automatic locking is realized, facilitating to prevent the free rotation of the synchronization member ( 31 ) and the vertical reel ( 3 ), thus achieving safety control. By providing the manual unlocking slider ( 41 ), it facilitates the manual unlocking of the automatic locking mechanism. Furthermore, the arrangement of the pressing member ( 51 ) facilitates the hindering of the movement of the manual unlocking slider ( 41 ) both when the pressing member ( 51 ) is not pressed and after resetting. That is, when the pressing member ( 51 ) is not pressed and after resetting, it prevents the manual unlocking slider ( 41 ) from changing the working state of the automatic locking mechanism, thus realizing safety control. In order to change the working state of the automatic locking mechanism, first the pressing member ( 51 ) needs to be pressed, before you are able to manually unlock the slider ( 41 ) to reset from the unlocked position or move from the reset position to the unlocked position. In addition, when the manual unlocking slider ( 41 ) is in the reset position, the automatic locking mechanism is in the locked state, so that when the user only presses the pusher ( 51 ) and does not operate the manual unlocking slider ( 41 ), the automatic locking mechanism is still in the locked state, and so it is generally difficult for children to perform the two-step unlocking operation, resulting in real practicability. The pull ring ( 21 ) is arranged at the free end of the gate mesh ( 2 ) to facilitate pulling out the gate mesh ( 2 ) and hook it onto the buckle seat ( 6 ) arranged on the other side, thus achieving the gate function.
