Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically, to a lock cylinder mounting structure. Background Technology

[0002] As the name suggests, a door lock is a device used to lock a door to prevent others from opening it. The lock cylinder is the core part that works with the key and can rotate to drive the bolt. The lock cylinder is the main component that controls the opening of the door lock and is the internal heart of the lock.

[0003] The lock cylinder is generally located at the upper end with a keyhole that matches the key, and at the lower end it engages with a clutch mechanism inside the lock body via a linkage to open or lock the door.

[0004] However, the existing lock cylinder is directly built into the door handle and cannot be moved in the vertical direction. This means that the distance the square shaft at the bottom of the door handle passes through the door handle is fixed. When the door lock is used on a thin door panel, the length of the square shaft is too long, resulting in poor applicability of the door lock. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lock cylinder installation structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A lock cylinder mounting structure includes a door handle, a square shaft, and a lock cylinder assembly. The lower end of the handle head of the door handle is provided with a square shaft hole for inserting the square shaft, and the upper end is provided with a mounting cavity for mounting the lock cylinder assembly. The square shaft hole is connected to the mounting cavity.

[0008] The lock cylinder assembly includes a lock cylinder and a telescopic spring, which are built into the mounting cavity from bottom to top.

[0009] The lower end of the lock cylinder abuts against the square shaft, and its upper end abuts against the telescopic spring. The telescopic spring allows the square shaft and the lock cylinder to be telescopically mounted on the handle.

[0010] The present invention is further provided with: a lock cylinder mounting sleeve is provided in the mounting cavity, and the lock cylinder is rotatably mounted in the lock cylinder mounting sleeve;

[0011] The lock cylinder mounting sleeve has a guide block longitudinally arranged on its side wall, and the mounting cavity has a guide groove adapted to the guide block on its side wall; the lock cylinder moves up and down in the mounting cavity with the lock cylinder mounting sleeve.

[0012] The present invention is further provided with an insertion hole on the end cap that corresponds to the keyhole of the lock cylinder.

[0013] The present invention is further provided with: an opening at the upper end of the mounting cavity, and an end cap at the opening;

[0014] The upper end of the telescopic spring abuts against the lower end, and the lower end abuts against the lock cylinder.

[0015] The beneficial effects of this utility model are as follows: The square shaft of the door lock is inserted into the square shaft hole, and the lock cylinder and the telescopic spring are built into the mounting cavity from bottom to top. The square shaft hole is connected to the mounting cavity. The lower end of the lock cylinder abuts against the square shaft, and its upper end abuts against the telescopic spring. When the door lock is installed on a thinner door panel, the square shaft will press the lock cylinder upward and compress the lock cylinder to compress the spring, shortening the length of the square shaft extending from the handle head, so as to be suitable for installation on thinner door panels. That is, by telescopically setting the lock cylinder and the square shaft on the door handle, the length of the square shaft extending from the door handle can be adjusted, so that the door lock can be used on door panels of different thicknesses, improving the applicability of the product.

[0022] See attached document Figures 1 to 5 The present invention provides a more detailed description of the installation structure of a lock cylinder.

[0023] A lock cylinder mounting structure includes a door handle 1, a square shaft 4, and a lock cylinder assembly 2. The lower end of the handle head 11 of the door handle 1 is provided with a square shaft hole 112 for inserting the square shaft 4, and the upper end is provided with a mounting cavity 111 for mounting the lock cylinder assembly 2. The square shaft hole 112 communicates with the mounting cavity 111. The upper end of the mounting cavity 111 is provided with an opening, and an end cap 12 is provided at the opening. The end cap 12 is fixed to the handle head 11 by screws. The upper end of the telescopic spring 22 abuts against the end cap, and the lower end abuts against the lock cylinder 21.

[0024] The lock cylinder assembly 2 includes a lock cylinder 21 and a telescopic spring 22, which are built into the mounting cavity 111 from bottom to top; the end cap 12 is provided with a through hole 121 corresponding to the key hole of the lock cylinder 21;

[0025] The lower end of the lock cylinder 21 abuts against the square shaft 4, and its upper end abuts against the telescopic spring 22. The telescopic spring 22 allows the square shaft 4 and the lock cylinder 21 to be telescopically mounted on the handle head 11.

[0026] The square shaft 4 of the door lock is inserted into the square shaft hole 112. The lock cylinder 21 and the telescopic spring 22 are built into the mounting cavity 111 from bottom to top. The square shaft hole 112 is connected to the mounting cavity 111. The lower end of the lock cylinder 21 abuts against the square shaft 4, and its upper end abuts against the telescopic spring 22. When the door lock is installed on a thinner door panel, the square shaft 4 will press the lock cylinder 21 upward and compress the spring, shortening the length of the square shaft 4 extending from the handle head 11, so as to be suitable for installation on thinner door panels. That is, by telescopically setting the lock cylinder 21 and the square shaft 4 on the door handle 1, the length of the square shaft 4 extending from the door handle 1 can be adjusted, so that the door lock can be used on door panels of different thicknesses, improving the applicability of the product.

[0027] When assembling the door lock, first pass the lower end of the square shaft 4, which has a retaining ring 41 at the upper end, through the mounting cavity 111 to the square shaft hole 112, and then through the square shaft hole 112. The retaining ring 41 restricts the upper end of the square shaft 4 to the bottom of the mounting cavity 111 to prevent the square shaft 4 from falling off the handle head 11; at the same time, it allows the square shaft 4 to move up and down within the square shaft hole 112.

[0028] The mounting cavity 111 is provided with a lock cylinder mounting sleeve 3, and the lock cylinder 21 is rotatably mounted in the lock cylinder mounting sleeve 3;

[0029] The lock cylinder mounting sleeve 3 has a guide block 31 longitudinally arranged on its side wall, and the mounting cavity 111 has a guide groove 1111 adapted to the guide block 31 on its side wall; the lock cylinder 21 moves up and down in the mounting cavity 111 along with the lock cylinder mounting sleeve 3; the lock cylinder 21 moves up and down in the mounting cavity 111 along with the lock cylinder mounting sleeve 3 under the guidance of the guide block 31, thereby improving the stability of the product structure.

[0030] 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 by this utility model. 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.
