[0027] See attached Figures 1 to 7 The utility model discloses a lock core installation structure, including a lock core and a lock core accommodating body 1 for accommodating the lock core. The lock core accommodating body 1 is such as a lock core seat on a handle (as shown in the attached drawings) or a lock core seat on a lock shell. The lock core is inserted into a lock core installation hole of the lock core seat. The lock core includes a lock core 2 and a lock core casing 3. The lock core casing 3 includes a lock core installation casing 31 formed with a lock core cavity 311. The lock core 2 is confined in the lock core cavity 311 and can rotate. The lock core 2 is provided with an anti-disassembly component 21 for confining the lock core 2 in the lock core cavity 311. The anti-disassembly component 21 is unlocked by matching After the key is unlocked, the lock core 2 can be pulled out of the lock core cavity 311. The radial side of the lock core mounting sleeve 31 is formed with a side portion 32, and the side portion 32 is provided with a lock installation cavity 321. The lock installation cavity 321 has an anti-disassembly limit opening 3211 connected to the lock core cavity 311, and a lock head extension opening 3212; a locking member 5 is assembled in the lock installation cavity 321, and the locking member 5 is movably arranged in the lock installation cavity 321. The locking member 5 is restricted in the lock installation cavity 321 to switch between a locked position and an unlocked position. The locking member 5 has a locking position with the lock head. The lock head 51 corresponding to the position of the extension opening 3212 and the anti-disassembly locking portion 52 corresponding to the anti-disassembly limiting opening 3211 are provided in the lock core housing 1 with a lock opening 11 for locking and unlocking with the lock head 51. When the locking member 5 is in the locked position, the lock head 51 extends out of the lock head extension opening 3212 and is inserted into the lock opening 11 to limit the lock core housing 3 in the lock core housing 1. At the same time, the anti-disassembly locking portion 52 corresponds to the position of the anti-disassembly limiting opening 3211 and can be limited by the lock core 2 stopper placed in the lock core cavity 311. When the lock core 2 exits the lock core cavity 311, the locking member 5 It can be operated to the unlocking position to make the lock core housing 3 and the lock core housing 1 detachable; in order to make the structure simple and compact and reliable, the locking member 5 is preferably configured in the lock installation cavity 321 by linear sliding. Of course, as a feasible solution of the utility model, the locking member can also be designed to rotate and swing, such as swinging along the axial direction of the lock core, or swinging along the radial direction of the lock core; but the structural strength of the rotating locking member is insufficient, so the locking member is preferably configured in the lock installation cavity 321 by sliding, and the locking member 5 is configured with a locking spring 4 that drives the locking member 5 to the locked position. The locking spring 4 can usually be a coil spring.

[0028] In order to further facilitate the disassembly and assembly of the lock core housing 3, the following optimization design is performed: the lock head 51 has an unlocking inclined surface 511. As the lock core housing 3 is pulled out of the lock core receiving body 1, the unlocking inclined surface 511 abuts against the edge of the lock port 11 to force the locking member 5 to retreat to the unlocking position. Correspondingly, the lock head 51 is also provided with a push-up inclined surface 512 opposite to the unlocking inclined surface 511. The push-up inclined surface 512 of the lock head 51 is pushed by an external force to force the lock head 51 to retract into the lock component installation cavity 321 to avoid. Specifically, the push-up inclined surface 512 of the lock head 51 abuts against the lock core receiving body 1. As the lock core housing 3 is inserted, the lock head 51 is forced to retract into the lock component installation cavity 321 until the lock head 51 corresponds to the position of the lock port 11. The lock head 51 is inserted into the lock port 11 under the drive of the locking spring 4. In this way, the lock core housing can be directly pulled out and inserted for disassembly and assembly, and the operation is simple and convenient.

[0029] In order to facilitate the removal of the cylinder housing 3 from the lock cylinder housing 1, a gripping end exposed outside the lock cylinder housing 1 is provided at the top of the side portion 32, so as to facilitate the use of tools or hands to hold the cylinder housing. The gripping end includes two recesses 322 and a partition 323 located between the two recesses 322. Of course, the specific structure of the gripping end can be adjusted as required, such as a hook hole, a gripping piece, etc., and of course, the cylinder housing can also be directly gripped to remove the cylinder housing from the lock cylinder housing.

[0030] The anti-disassembly locking portion 52 on the locking member 5 is designed as an arc-shaped concave wall, which is adapted to the outer circumferential surface of the lock core 2. Such an arc-shaped concave wall has a simple structure, and compared with the anti-disassembly locking portion being a convex head protruding laterally, no additional avoidance space is required, and the lock core does not need to be specially designed, and the structure is simple and compact.

[0031] A limiter installation groove 324 is provided on the side portion 32 at the side of the lock head extension opening 3212, and a limiter 6 is installed in the limiter installation groove 324. As a relatively simple design, the limiter 6 is a screw, and the locking member 5 is installed into the lock member installation cavity 321 along the lock head extension opening 3212 and then stopped in the lock member installation cavity 321 by the head end of the screw. The limiter installation groove is a countersunk hole, and the head of the screw is buried in the limiter installation groove.

[0032] Usually, the lock core 2 is provided with a lock core blade assembly 2-1 or a pin assembly, which locks and unlocks the rotation of the lock core relative to the lock core cavity 311. Only when a matching unlocking key is inserted can the lock core blade assembly or the pin assembly be driven to unlock, and the lock core can be rotated in the lock core cavity 311 to perform the opening and closing operations of the lock; in the utility model, the anti-dismantling assembly can adopt the existing technical design recorded in the background technology; in this specific embodiment, the anti-dismantling assembly 21 includes an anti-dismantling blade 211 and a blade reset member 212, a blade groove 22 is provided on the lock core 2, the anti-dismantling blade 211 and the blade reset member 212 are installed in the blade groove 22, the anti-dismantling blade 211 is movably inserted in the blade groove 22, and a stop groove 3111 is provided in the lock core cavity 311, such as Figure 6 As shown, the anti-disassembly blade 211 can be retracted into the blade groove 22 under the driving of the disassembly key, so that the lock core and the lock core housing 3 can be disassembled. Figure 7 As shown, the blade reset member 212 drives the anti-disassembly blade 211 to extend out of the blade slot 22 and insert into the stop slot 3111 to restrict the lock core 2 in the lock core housing 3. The anti-disassembly blade is arranged below the lock core blade assembly or the pin assembly of the lock core, so the disassembly key only needs to add a tooth shape with anti-disassembly blade drive, and the structure is simple.

[0033] When the lock core is installed, the locking member 5 is driven by the locking spring 4, and the lock head 51 extends out of the lock head extension opening 3212 and inserts into the lock opening 11. The arc-shaped concave wall of the locking member 5 corresponds to the anti-disassembly limit opening 3211, and the arc-shaped concave wall is attached to the outer circumferential wall of the lock core 2. The locking member 5 is restricted in the locking position, so the lock core housing 3 is restricted in the lock core accommodating body 1, and the lock core 2 is restricted in the lock core cavity 311 by the anti-disassembly component 21 and cannot be removed. Therefore, the anti-disassembly limitation of the lock core housing 3 is achieved by the inserted lock core 2, and the structural design is ingenious, simple and compact.

[0034] When disassembly is required, the unlocking key is inserted to unlock the anti-disassembly component 21, and the lock core 2 is pulled out from the lock core cavity 311 of the lock core shell 3, so that the lock core can be replaced independently; at the same time, the locking member 5 is no longer restricted by the lock core 2, and the locking member 5 can be operated to the unlocking position, so that the lock core shell 3 and the lock core container 1 can be disassembled, wherein the locking member 5 can be operated by an independent operating end exposed on the side, but this will increase the design difficulty and make the structure complicated; while the unlocking key is used The lock bevel 511 is designed so that the lock head 51 can be touched and retracted, and the lock core shell 3 can be directly pulled out, which is easy to operate. Similarly, when the lock core shell 3 is installed, the lock head 51 can be retracted and avoided by touching the push bevel 512, which provides convenience for the installation of the lock core shell 3. The lock core shell 3 can be directly inserted into the lock core container 1. At the same time, since the locking component 5 is designed for linear sliding, the touch-type avoidance of the lock head is smoother and more feasible; the pinching end formed on the top surface of the side is convenient for fixing the lock core shell and pulling it out of the container.

[0035] It not only has the characteristics of the lock core in the traditional lock core being independently disassembled and replaced, but also can realize the overall disassembly and replacement of the lock core, which is more flexible to use, and its structure is simple and compact and easy to implement.
