In this embodiment, the first lock core sleeve 210 can be adjusted to slide relative to the adjusting rod 230, the second lock core sleeve 220 can also be adjusted to slide relative to the adjusting rod 230, and the first lock core sleeve 210 and the second lock core sleeve 220 can also be adjusted to slide relative to the adjusting rod 230 simultaneously, so that the distance between the first lock core sleeve 210 and the second lock core sleeve 220 is changed, and further the door with different thicknesses is adapted, the situation that the part of the lock core sleeve, which is caused by too long lock core sleeve, extends beyond the door body can be avoided, the appearance is attractive, the situation that the two ends of the lock core sleeve, which are caused by too short lock core sleeve, cannot be flush with the two sides of the door body can be avoided, and the lock core sleeve is fixed more stably relative to the door body and is not easy to shake.

In a specific embodiment, the end of the first lock cylinder sleeve 210 away from the second lock cylinder sleeve 220 is flush with the end of the transmission shaft 100, and the first lock cylinder sleeve 210 is limited to move relative to the transmission shaft 100 in the axial direction of the transmission shaft 100, but the second lock cylinder sleeve 220 can be adjusted to move relative to the adjustment rod 230 and the transmission shaft 100 in the axial direction of the transmission shaft 100 by adjusting the adjustment rod 230 to move relative to the first lock cylinder sleeve 210 in the axial direction of the transmission shaft 100, so that the adjustment requirement is met, and the end of the first lock cylinder sleeve 210 away from the second lock cylinder sleeve 220 is always flush with the end of the transmission shaft 100.

Based on the above embodiment, in an embodiment, the lock cylinder structure 10 further includes a first limiting member 310 that limits the movement of the first lock cylinder jacket 210 relative to the adjustment rod 230 and a second limiting member 320 that limits the movement of the second lock cylinder jacket 220 relative to the adjustment rod 230. Because the first lock cylinder sleeve 210 is limited to move relative to the transmission shaft 100, the first lock cylinder sleeve 210 can be limited to move relative to the adjusting rod 230 by the first limiting piece 310, and the second lock cylinder sleeve 220 can be limited to move relative to the adjusting rod 230 by the second limiting piece 320, so that after the distance between the first lock cylinder sleeve 210 and the second lock cylinder sleeve 220 is adjusted, the first lock cylinder sleeve 210, the second lock cylinder sleeve 220, the adjusting rod 230 and the transmission shaft 100 can be kept in a relatively static state, subsequent installation is facilitated, and the use stability is improved.

In this embodiment, when the length of the lock cylinder structure 10 needs to be adjusted, the first screw is unscrewed, so that the adjusting rod 230 can be moved relative to the first lock cylinder sleeve 210, so that the distance between the first lock cylinder sleeve 210 and the second lock cylinder sleeve 220 can be changed, thereby completing the length adjustment of the lock cylinder structure 10, or the second screw is unscrewed, so that the second lock cylinder sleeve 220 can be moved relative to the adjusting rod 230 and the transmission shaft 100, thereby changing the distance between the first lock cylinder sleeve 210 and the second lock cylinder sleeve 220, thereby completing the length adjustment of the lock cylinder structure 10, or the first lock cylinder sleeve 210 and the second lock cylinder sleeve 220 can be unscrewed simultaneously, thereby adjusting the distance between the first lock cylinder sleeve 210 and the second lock cylinder sleeve 220.

It should be noted that in some embodiments, the first screw and the second screw may be replaced by a latch.

In one embodiment, the adjusting rod 230 is provided with a fixing hole 233 along a radial direction thereof. By providing the fixing hole 233, the door and the fixing hole 233 can be fixed together by a screw, so that the adjusting rod 230 can be limited to move relatively to the door along the axial direction thereof, and when the door is designed, a design error may exist in the position of the hole on the door, which is matched and fixed with the fixing hole 233, in this embodiment, since the adjusting rod 230 can move relatively to the first lock cylinder sleeve 210 and the second lock cylinder sleeve 220, the position of the adjusting rod 230 is adjusted, so that the fixing hole 233 corresponds to the hole on the door, which is matched and fixed with the fixing hole 233, and thus, the problem that the installation is impossible or the installation is not attractive due to the design error in the position of the hole on the door, which is matched and fixed with the fixing hole 233, can be avoided.

Of course, in other embodiments, the fixing hole 233 may be formed on the first lock core sleeve 210 or the second lock core sleeve 220.

In one embodiment, the lock cylinder structure 10 further includes a shifting block 410 slidably disposed on the drive shaft 100 and a fixing member 420 for restricting movement of the shifting block 410 relative to the drive shaft 100. In this embodiment, since the shifting block 410 can slide relative to the transmission shaft 100, the position of the shifting block 410 relative to the transmission shaft 100 can be adjusted according to the actual installation requirement, so that the problem that the shifting block 410 is not easy to install or cannot work normally after installation due to design errors can be solved.

Of course, in other embodiments, the third screw may be replaced by a latch.

In one embodiment, the drive shaft 100 is axially provided with a drive hole 102, and the lock cylinder structure 10 further includes a drive member 510 mounted in the drive hole 102, wherein the drive member 510 is capable of moving along the axial direction of the drive shaft 100 and is not rotatable about the axis of the drive shaft 100. Because the driving medium 510 can not rotate around the axis of the driving shaft 100, the driving medium 510 can be rotated to drive the driving shaft 100 to rotate, and then the shifting block 410 is driven to rotate, so that the lock or the opening of the lock cylinder structure 10 can be realized, and thus the door can be locked and opened.

The lock in this embodiment includes a lock body 20, a lock tongue 30 disposed on the lock body 20, and the lock cylinder structure 10 in any of the above embodiments, and the pulling block 410 is used to drive the lock tongue 30 to stretch or retract to lock or unlock. Because the lock core structure 10 can be driven by adjusting the first lock core sleeve 210 relative to the driving shaft 100 or adjusting the second lock core sleeve 220 relative to the driving shaft 100, the first lock core sleeve 210 and the second lock core sleeve 220 can be simultaneously adjusted to move relative to the driving shaft 100, so that the distance between the first lock core sleeve 210 and the second lock core sleeve 220 is changed, and further, the door with different thicknesses can be adapted, the situation that the part of the lock core sleeve, which is caused by too long lock core sleeve, extends beyond the door body can be avoided, the appearance is more attractive, the situation that the two ends of the lock core sleeve, which are caused by too short lock core sleeve, cannot be flush with the two sides of the door body can be avoided, and the lock core sleeve is fixed more stably relative to the door body and is not easy to shake. Therefore, the influence of the environment on the lock in the embodiment is greatly reduced, and the adaptation environment is wider.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
