[0014] The utility model will be further detailed in the following with the embodiment given by the accompanying drawings.

[0015] Referring to Figs. 1-3 As shown in the figure, a lock body handle mounting structure, including lock body, install on the lock body handle, fixedly connected on the lock body dust cover, the dust cover is located between lock body and handle, the top of dust cover is equipped with the positioning assembly for handle installation, the handle is equipped with the mounting hole that communicates with lock body, the mounting hole is rotatably connected with pivot, the one end of pivot is equipped with lock tongue close to lock body, the mounting hole on lock body is equipped with the gap for lock tongue, by rotating pivot makes lock tongue and gap dislocation to limit handle separates from lock body, the handle is equipped with the plug block that inserts lock body.

[0016] Dust cover is used for covering emergency lock cylinder on lock body, handle is equipped with window that communicates with emergency lock cylinder in the embodiment, the outside of window is equipped with cover plate, dust cover is fixed on the one side of lock body towards handle through screw or buckle, when installing, first, handle is positioned through positioning assembly, makes handle after assembling through translation and pushes in, then, the pivot is passed through the mounting hole of handle, makes the lock tongue of pivot end portion aligns the gap on lock body mounting hole and passes through, at this time, pivot is rotated, drives lock tongue synchronous rotation, until lock tongue and gap completely dislocation, lock tongue abuts on the inner wall of lock body mounting hole, further limit handle moves along the direction away from lock body, the fixation of handle is completed, the position of lock body corresponding plug block is equipped with the insertion slot for plug block insertion, plug block installation in insertion slot can further improve the stability after handle installation.

[0017] In one alternative embodiment, the positioning assembly includes several positioning seats arranged on the top of the dust cover and several positioning posts disposed on the handle. The positioning seats are provided with positioning grooves for mounting the positioning posts. The top of the positioning grooves is open. The positioning posts are installed in the positioning grooves by pressing and can move along the axial direction of the positioning grooves after installation.

[0018] The positioning base and dust cover are integrally formed. The number and position of the positioning pins correspond to the positioning base. During installation, align the positioning pins with the opening of the positioning groove, and press the handle to insert the positioning pins into the positioning groove. The axial length of the positioning groove is greater than the length of the positioning pin, so that the positioning pins can move along the axial direction of the positioning groove after installation. This design avoids the handle from being misaligned during installation and can also distribute the force on the handle.

[0019] Further optimization can be achieved by selecting the following method to prevent the pivot from coming off the handle: the pivot is provided with a flange to prevent it from coming off the handle, the diameter of the flange is larger than the diameter of the mounting hole, and the handle is provided with a groove for mounting the flange. This design can effectively prevent the pivot from coming off the mounting hole of the handle during use and ensure a stable connection between the pivot and the handle.

[0020] Specifically, further optimization can be achieved by selecting the following method: an annular hole is provided on the side of the flange facing the lock body, and a return spring is provided in the annular hole. The return spring is sleeved on the rotating shaft, with one end of the return spring abutting against the lock body and the other end abutting against the bottom of the annular hole. A gap is provided between the end of the flange near the lock body and the lock body.

[0021] The return spring presses the shaft firmly onto the handle, preventing it from rotating arbitrarily when not in operation after installation. A gap is provided between the flange and the lock body, allowing the handle to be pushed towards the lock body during disassembly and replacement, thus separating the lock body from its inner wall and preventing noise from metal expansion during rotation.

[0022] Further optimization can be achieved by selecting the following method: a damper is provided between the flange and the groove. The damper reduces the vibration of the rotating shaft caused by external force. At the same time, the damper can prevent the rotating shaft from rotating randomly in the non-operating state and ensure the stability of the locking tongue position.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
