In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the invention. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and so on are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this embodiment and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation , so it should not be construed as limiting the protection scope of this embodiment.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the embodiment of the present invention provides a kind of protection structure, is used for connecting driving part 10 and driven part 20, and the guide hole 201 that lengthwise direction can be arranged obliquely on the driven part 20, this protective structure comprises movable part 1, and one end of this movable part 1 is used for being hinged with driving part 10, and the other end is used for being hinged in guide hole 201; The surface 211 corresponds to the extending direction of the guide hole 201; when the driving force of the driving member 10 exceeds the limit value, the movable member 1 can abut against the limit surface 211 under the guidance of the guide hole 201, so that the driving member 10 stops driving.

The protective structure can be applied to a lockset. The driver 10 can be a bolt plate, and the driven part 20 can be a component connected with the bolt plate such as a drive plate. The guide hole 201 can be arranged on the drive plate, and one end of the movable part 1 can be hinged with the bolt plate, and the other end is hinged in the guide hole 201. The fixed part 2 can be arranged on the base of the lockset.

The protection structure provided by the embodiment of the present invention realizes that when the driving force of the driving part exceeds the limit value, the movable part can move toward the limit surface of the fixed part under the guidance of the guide hole until it abuts against the limit surface, so that the driving part stops driving movement by providing a guide hole inclined in the length direction on the driven part and setting the movable part and the fixed part. In the lockset, the deadbolt plate can be the driving part, and the parts inside the lockset that are driven and connected with the deadbolt plate are the driven parts. When the lock in the locked state is forcibly unlocked, the deadbolt plate drives the movable part to the limit surface of the fixed part under the guidance of the guide hole, so that the deadbolt plate stops the driving movement, and the parts inside the lockset are avoided from being damaged.

In an optional embodiment, referring to FIG. 1 , the movable part 1 can have a low top; and the fixed part 2 can be located on one side of the low top, 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 through the guide hole 201 to move normally through the fixed part 2. That is to say, the setting position of the fixing part 2 should not interfere with the normal operation of the lockset, that is, the setting position of the fixing part 2 will not affect the movement of the bolt plate, that is, when the driving force of the bolt plate does not exceed the limit value, the movable part 1 will not be guided by the guide hole 201 and move to the limit surface 211, but will be connected with the drive plate through the guide hole 201 to realize the driving effect of the bolt plate on the driver, which is convenient to use.

In an optional embodiment, referring to Fig. 5 and Fig. 6, the fixing part 2 can include a body 21, which can be provided with a first through hole 212; a blocking part 22, which can be provided with a second through hole 221, and which is blocked at one end of the first through hole 212; At one end of the second through hole 221 , the elastic member 24 is blocked in the first through hole 212 by the blocking member 22 ; the pin body 23 contacts and supports the movable member 1 .

In the above-mentioned embodiment, due to the limiting effect of the elastic member 24, the pin body 23 is in a suspended state to support the movable member 1, which can prevent the movable member 1 from accidentally sliding down to one end of the guide hole 201 and prevent the movement of the bolt plate without being subjected to a driving force exceeding the limit value. In the case that the driving force exceeding the limit value has been applied, during the movement of the movable part 1, since the movable part 1 also rotates counterclockwise with the hinge pin as the center of rotation, that is, the pin body 23 is pressed down, and the elastic part 24 is in a compressed state. In this embodiment, the elastic member 24 may be a cylindrical spring.

In an optional embodiment, referring to FIG. 5 and in conjunction with FIG. 1 , the pin body 23 has a supporting surface 232 in contact with the movable part 1. The supporting surface 232 can be a hemispherical surface, so that the pin body 23 forms a point contact with the movable part 1. In this case, the isotropic nature of the contact can be used to reduce the wear at the contact point, thereby improving the service life of the pin body 23.

In an optional embodiment, referring to FIG. 1 , the end surface of the movable part 1 against the tip can be an inclined surface inclined away from the limiting surface 211 , and the inclined surface can smoothly transition with the side of the movable part 1 . In this case, even if the apex of the movable part 1 has contacted the limiting surface 211, the driving force applied to the bolt plate is still increasing, since the left contact surface of the movable part 1 is inclined from the apex to the upper right, it can continue to rotate counterclockwise at a small angle with the hinge pin as the center of rotation, thereby playing a buffering role and improving the service life of the movable part 1.

In an optional embodiment, referring to FIG. 1 , a limiting projection 25 may be provided on the fixing member 2 , and a limiting surface 211 may be provided on the limiting projection 25 .

In an optional embodiment, referring to FIG. 7 , one end of the first through hole 212 is provided with a first annular shoulder 213 extending inward, and the pin body 23 is provided with a second annular shoulder 231 extending outward; the pin body 23 can be driven by the elastic member 24 to make the first annular shoulder 213 and the second annular shoulder 231 abut; the inner diameter of the first annular shoulder 213 is adapted to the outer diameter of the pin body 23 and the inner diameter of the second through hole 221; The outer diameter of 24 matches the inner diameter of the first through hole 212 . In this way, the pin body 23 can always move in a straight line without deflection under the constraints 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 during the axial movement in the first through hole 212, and the phenomenon that the pin body 23 is difficult to reset due to deflection during the movement process can be avoided.

The embodiment of the present invention can provide a protection method based on the above protection structure, the method includes that when the driving force of the driving member exceeds the limit value, the movable member, driven by the driving force, moves along the guide hole toward the limiting surface of the fixing member until it abuts against the limiting surface, so that the driving member stops the driving movement.

Further, the protection solution may also include that when the driving force of the driving part does not exceed the limit value, the movable part drives the driven part through the guide hole to move normally through the fixed part. Specifically, this step may include that when the driving force of the driving part does not exceed the limit value, the movable part drives the driven part through the guide hole to move normally under the support of the pin body of the fixing part.
