When it is necessary to remove the lock cylinder body 4 from the lock housing body 1, press the sliding cover 2 at the side opening 101. After the sliding cover 2 releases its latch on the lock cylinder body 4, the lock cylinder body 4 can slide inside the lock housing body 1 and be pulled out through the side opening 101. This structure makes the disassembly and assembly process of the lock cylinder body 4 faster and the replacement of the lock cylinder body 4 more convenient.

[0035] In a preferred embodiment of this utility model, two pressure strips 102 are fixed on the lock housing body 1; two parallel pressure strips 102 are fixed inside the lock cylinder body 4; fixing strips 402 are provided on both the left and right sides of the lock cylinder body 4; the pressure strips 102 press the fixing strips 402 against the bottom cover 3; the two pressure strips 102 are respectively attached to the left and right sides of the lock cylinder body 4.

[0036] The lock cylinder body 4 is limited on the left and right sides of the lock shell body 1 by the pressure strips 102 on both sides; the pressure strips 102 press the fixing strip 402 against the bottom cover 3 with less pressure, so the friction between the lock cylinder body 4 and the bottom cover 3 and the pressure strips 102 is less.

[0037] Furthermore, after the pressure strip 102 abuts against the fixing strip 402, the lock cylinder body 4 is attached to the bottom cover 3, so that the lock cylinder body 4 can move to pull out or insert into the side opening 101 between the two pressure strips 102, realizing the sliding connection between the lock cylinder body 4 and the lock shell body 1; and the structure of realizing the sliding connection between the lock cylinder body 4 and the lock shell body 1 is simple, reducing the cost of the lock.

[0038] As a preferred embodiment of this utility model, a chamfered surface 10202 is provided between the end face of the pressure strip 102 near the side opening 101 and the surface of the pressure strip 102 used to fit against the fixing strip 402; the chamfered surface 10202 is used to guide the fixing strip 402 when the lock cylinder body 4 is inserted, so that the lock cylinder body 4 can be inserted into the lock shell body 1 more smoothly.

[0039] In a preferred embodiment of this utility model, a reinforcing rib 10201 is fixed between the pressure strip 102 and the lock body 1.

[0041] The sliding cover 2 has a groove-shaped structure. When assembling the sliding cover 2 with the lock housing body 1, the spring 205 is first compressed, and then aligned with and inserted through the limiting plate groove 20102 and the limiting plate 10301. After the limiting plate 10301 has completely passed through the limiting plate groove 20102, the spring 205 is released. The elastic force of the spring 205 pushes the sliding cover 2 to slide, causing the connecting strip 10302 to slide in the sliding groove 20101. The limiting plate 10301 and the limiting plate groove 20102 are misaligned. The limiting plate 10301 presses the wing plate 203 against the inner wall of the lock housing body 1, realizing the sliding connection between the sliding cover 2 and the lock housing body 1. Overcoming the elastic force of the spring 205, pressing the pressure pin 204 allows the sliding cover 2 to slide in the lock housing body 1, causing the sliding cover 2 to release the latch on the lock cylinder body 4, and the lock cylinder body 4 can be pulled out from inside the lock housing body 1.

[0042] Under normal conditions, or when the sliding cover 2 is compressed to a certain extent, the limiting plate 10301 is also aligned with the sliding groove 20101, and the limiting plate 10301 will not be released from the limiting plate groove 20102.

[0043] In a preferred embodiment of this utility model, the sliding cover 2 is provided with a latching groove 202; a fixing post 401 is fixed on the lock cylinder body 4; the latching groove 202 is composed of a first straight groove 20201 and a second straight groove 20202 arranged perpendicularly to the first straight groove 20201; one end of the second straight groove 20202 is connected to one end of the first straight groove 20201; the other end of the second straight groove 20202 extends through to the side surface of the sliding cover 2; the diameter of the fixing post 401 is equal to the width of the first straight groove 20201; the diameter of the fixing post 401 is less than or equal to the width of the second straight groove 20202. During the installation of the lock cylinder body 4, first press the sliding cover 2 so that the fixing post 401 is aligned with the second straight groove 20202. Then, as the lock cylinder body 4 is inserted into the lock shell body 1 from the side opening 101, the fixing post 401 is also inserted from the second straight groove 20202. When the lock cylinder body 4 is inserted into the lock shell body 1, the fixing post 401 is aligned with the first straight groove 20201. Release the pressure on the pressure pin 204, and the spring 205 pushes the sliding cover 2 to reset along the length of the connecting strip 10302, so that the fixing post 401 is stuck into the first straight groove 20201, and the lock cylinder body 4 cannot be pulled out from the lock shell body 1.

[0044] As a preferred embodiment of this utility model, a wedge-shaped surface 20203 is provided between the side surface of the second straight groove 20202 near the first straight groove 20201 and the opening end face of the second straight groove 20202; when the pressing pin 204 is not pressed, the wedge-shaped surface 20203 is aligned with the fixing post 401 inserted into the lock shell body 1.
