[0002] The lock core is the main part that controls the opening of the lock. It is the heart of the lock and refers to the core part that can rotate with the key and drive the bolt to move. The main function of the lock core is to transmit torque from the lock core to drive other parts of the lock to achieve the purpose of unlocking and locking.

[0003] Most traditional lock cores are of fixed length and cannot meet the environmental requirements of different door thicknesses. When matching the lock core, it is usually necessary to actually measure the length before configuring the lock core. After adjusting the length, the distance between each part is unstable, which is very inconvenient during installation and needs further improvement.

[0004] Therefore, it is necessary to invent a lock core with adjustable length to solve the above problems. Utility Model Content

[0008] Preferably, a plurality of groups of latch slots are provided at the bottom end of the main installation housing, and latches are movably connected inside the latch slots to accommodate the latches.

[0009] Preferably, the main mounting shell is consistent in height with the two sets of side mounting shells, and the main lock core is consistent in height with the two sets of side lock cores, to avoid the lock not working when the key is inserted.

[0010] Preferably, a dustproof shell is fixedly connected to one side of the side lock gallbladder, and a dustproof plate is rotatably connected to the interior of the dustproof shell. The dustproof shell and the dustproof plate are used together to prevent dust and water from entering the side lock gallbladder.

[0011] Preferably, a rubber block is fixedly connected to the inner wall of the dustproof plate, and the shape of the rubber block matches the lock hole of the side lock gallbladder, so that the dustproof function is enhanced through the cooperation between the dustproof plate and the rubber block.

A telescopic spring 206 is arranged inside the connecting block 205, and the telescopic spring 206 is used to limit the activity track of the limit rod 203. Both ends of the telescopic spring 206 are fixedly connected to the limiting block 207, and the side of the limiting block 207 away from the telescopic spring 206 is fixedly connected to the inner end of the limit rod 203, and the length of the telescopic rod 201 is limited by the cooperation of the limiting hole 202 and the limiting rod 203. In order to ensure the convenience and stability during installation, a main lock core 3 is installed on the top of the main installation shell 1, and the end of the telescopic rod 201 away from the main installation shell 1 is fixedly connected to the side installation shell 4, and the top of the side installation shell 4 is installed with a side lock core 5. The main lock core 3 and the side lock core 5 are used to realize the basic functions of the structure. A plurality of groups of latch grooves 8 are opened at the bottom of the main installation shell 1, and the latch grooves 8 are movably connected with latches, which are accommodated by the latch grooves 8. The main installation shell 1 is consistent in height with the two groups of side installation shells 4, and the main lock core 3 is consistent in height with the two groups of side lock cores 5, so as to avoid the key from being inserted into the lock. It cannot work, through the cooperation of the main installation shell 1 and the length adjustment mechanism 2, the distance adjustment between the side installation shell 4 and the main installation shell 1 is achieved by sliding the telescopic rod 201, and at the same time, the telescopic spring 206 drives the limit block 207 and the connecting block 205 to move to both sides, so that the limit rod 203 is plugged into the limit hole 202 to achieve limit, and when adjustment is needed, through the special shape of the limit hole 202 and the limit rod 203, the limit rod 203 can compress the limit block 207 to contract and plug into the limit hole 202 again when the telescopic rod 201 moves.

[0027] Refer to the instruction manual Figure 1-5 When the overall length of the structure needs to be adjusted, the telescopic rod 201 is first slid to adjust the distance between the side mounting housing 4 and the main mounting housing 1 to adapt it to actual needs. At the same time, the telescopic spring 206 drives the limit block 207 and the connecting block 205 to move to both sides, so that the limit rod 203 is plugged into the limit hole 202 to achieve limit. When adjustment is required, the special shape of the limit hole 202 and the limit rod 203 allows the limit rod 203 to press the limit block 207 to contract when the telescopic rod 201 moves. After canceling the limit of the two, the limit rod 203 is plugged into the limit hole 202 again, thereby finally fixing the length of the telescopic rod 201, so as to solve the problem that the actual length measurement needs to be carried out before installation before the lock core can be configured, and the distance between each part is unstable after the length is adjusted, which is very inconvenient during installation.

[0028] Refer to the instruction manual Figure 1-5 When the side lock gall 5 is not working, the dustproof shell 6 is used to prevent dust from entering the top of the side lock gall 5, and the dustproof plate 7 is used to prevent dust from entering the side of the side lock gall 5. The dustproof plate 7 is used to prevent dust from entering the side of the side lock gall 5, and the dustproof plate 7 is used to prevent dust from entering the side of the side lock gall 5. The dustproof plate 7 and the rubber block 9 are used to block the interior of the side lock gall 5 to increase the dustproof strength, thereby avoiding blockage of the side lock gall 5.
