As shown in fig. 1, 2, 3 and 4, an embodiment of the present invention provides a protection structure for connecting a driving element 10 and a driven element 20, wherein a guide hole 201 with a length direction inclined may be formed on the driven element 20, the protection structure includes a movable element 1, one end of the movable element 1 is used for being hinged with the driving element 10, and the other end of the movable element 1 is used for being hinged in the guide hole 201; the fixing part 2 is fixed in position, the fixing part 2 is provided with a limiting surface 211, and the limiting surface 211 corresponds to the extending direction of the guide hole 201; when the driving force of the driving element 10 exceeds the limit value, the movable element 1 can be abutted against the limiting surface 211 under the guiding action of the guiding hole 201, so that the driving element 10 stops driving movement.

The protection structure can be applied to a lock, the driving element 10 can be a door bolt plate, the driven element 20 can be a part in driving connection with the door bolt plate, such as a driving plate, the guide hole 201 can be arranged on the driving plate, one end of the moving element 1 can be hinged with the door bolt plate, the other end of the moving element is hinged in the guide hole 201, and the fixing element 2 can be arranged on a base of the lock.

According to the protection structure provided by the embodiment of the invention, the guide hole which is obliquely arranged in the length direction is arranged on the driven piece, and the movable piece and the fixed piece are arranged, so that when the driving force of the driving piece exceeds the limit value, the movable piece can move towards the direction of the limit surface of the fixed piece under the guide effect of the guide hole until the movable piece abuts against the limit surface, and the driving piece stops driving movement. In the tool to lock, the keeper board can be the driving piece, and the inside spare part of being connected with the keeper board drive of tool to lock is by the driving piece, and when the tool to lock that is in the block state was unblanked by force, the keeper board moved the moving part under the guide effect of guiding hole, supported in the spacing face of mounting to make the keeper board stop the drive motion, avoided the inside spare part of tool to lock impaired.

In an alternative embodiment, see fig. 1, the mobile element 1 may have a low top end; the fixed part 2 can be located at one side of the lower top end, so that when the driving force of the driving part 10 does not exceed the limit value, the movable part 1 can drive the driven part 20 to move normally through the fixed part 2 through the guide hole 201. That is to say, the setting position of mounting 2 should not cause the interference to the normal work of tool to lock, and the setting position of mounting 2 can not influence the removal of keeper board promptly, and when the drive power of keeper board did not exceed the limit value, moving part 1 can not be guided by guiding hole 201 and move to spacing face 211, but is connected with the drive plate through guiding hole 201, realizes the driving action of keeper board to the driving piece, convenient to use.

In the above embodiment, due to the restriction of the elastic component 24, the pin 23 is in the floating state to support the moving element 1, and the moving element 1 can be prevented from accidentally sliding down to one end of the guide hole 201 to prevent the movement of the door latch plate without receiving a driving force exceeding the limit value. When the driving force exceeding the limit value is applied, in the moving process of the movable element 1, the movable element 1 further rotates counterclockwise with the hinge pin as a rotation center, that is, the pin body 23 is pressed downward, and the elastic element 24 is in a pressed state, and thereafter, once the driving force exceeding the limit value is released, the movable element 1 can be easily reset by virtue of the stiff acting force of the elastic element 24. In this embodiment, the elastic member 24 may be a cylindrical spring.

In an alternative embodiment, referring to fig. 5 in combination with fig. 1, the pin 23 has a supporting surface 232 that contacts the moving part 1, and the supporting surface 232 may be a hemispherical surface, so that the pin 23 forms a point contact with the moving part 1, in which case the isotropic nature of the contact can be used to reduce wear at the contact, thereby improving the service life of the pin 23.

Therefore, the pin body 23 can always move linearly without deflection under the limiting action of the inner diameter of the first annular shoulder 213, the diameter of the pin body 23 and the inner diameter of the second through hole 221 in the process of moving in the axial direction in the first through hole 212, and the phenomenon that the pin body 23 is difficult to reset due to deflection in the moving process can be avoided.
