Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and specifically relates to a lock with a lock core as a lock bolt. Background Art

[0002] At present, the lock bolt of a folding lock is generally arranged at one end far away from the keyhole. For example, a folding lock with anti-warping disclosed in the application publication number CN104763249A has its lock bolt arranged at one end far away from the keyhole, and it requires many components to complete the locking function of the folding lock, so its production cost is relatively high. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is how to arrange the locking structure of the folding lock.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A lock with a lock core as a lock bolt includes a lock head and a lock body. A lock core is arranged in the lock head. One end of the lock body is fixed to the lock head, and the other end is a free end. The free end can be movably inserted into the lock head. A lock bolt part for locking the free end of the lock body is arranged on the lock core. The free end of the lock body has a bayonet. After the free end of the lock body is inserted into the lock head, the lock bolt part of the lock core and the bayonet of the free end of the lock body are in snap-fit by rotating the lock core. The lock bolt part is arranged at the end of the lock core where the key is inserted, and the inside of the lock bolt part is a hollow structure through which the key is inserted.

[0006] Preferably, the lock bolt part is at least one notch arranged on the surface of the lock core. A channel for the free end of the lock body to move is formed between the position of the lock core where the notch is located and the inner wall of the space. When the lock core is in the unlocked state, the free end of the lock body can be freely inserted and pulled out through this channel. When the lock core is in the locked state, the distance between the channels is reduced to form a clamping part to clamp the bayonet of the free end of the lock body.

[0007] Preferably, the bayonet is integrally C-shaped. There are two notches arranged on the corresponding lock bolt part. The two planes formed by the two notches are parallel to each other. The width of the part between the two notches is smaller than the width of the mouth of the bayonet. The diameter of the lock core at the position of the lock bolt part is smaller than the inner diameter of the bayonet and larger than the width of the mouth of the bayonet.

[0008] Preferably, the lock head further includes a housing and a core housing. The lock core is movably arranged in the core housing. A limiting mechanism for preventing the axial movement of the lock core is arranged between the lock core and the core housing.

[0009] Preferably, the limiting mechanism includes a long groove arranged on the outer surface of the lock core, and a limiting part extending into the long groove of the lock core is arranged on the corresponding core housing. The cooperation of the long groove and the limiting part enables the lock core to move only along the length direction of the long groove.

[0010] Preferably, the fixed end of the lock body is connected to one end of the outer shell, and the fixed end of the lock body is fixedly connected to the core shell through a connecting member.

[0011] Preferably, the lock core is a blade lock core or a pin tumbler lock core.

[0012] Preferably, the lock body is a folding rod, a chain or a steel cable.

[0013] The beneficial effects of the present utility model are as follows: by arranging the lock gate on the lock core, the internal parts of the lock are reduced, and the structure is simpler, thus reducing costs. Description of the Drawings

[0021] Embodiment

[0022] Please refer to Figures 1 - 6, as shown in the figure, a lock with a lock core 102 as a lock brake includes a lock head 100 and a lock body 200. In this embodiment, the lock body 200 is composed of several rods connected end to end, and can also be a steel cable or a chain on the market. The lock head 100 includes a housing 101, a lock core 102 and a core housing 103. The lock core 102 is movably arranged in the core housing 103. In this embodiment, the lock core 102 is a leaf lock core 102 or a pin tumbler lock core 102. In this embodiment, one end of the lock body 200 is fixed on the lock head 100, which is the fixed end 201, and the other end is the free end 202. In this embodiment, the fixed end of the lock body is connected to one end of the housing. The fixed end 201 of the lock body 200 is fixedly connected to the core housing 103 through a connecting piece 300. In this embodiment, the connecting piece 300 is a screw. There is a threaded mounting hole 2011 at the fixed end 201 of the lock body 200. The screw passes through the core housing 103 in the lock head 100 and is fixedly connected to the fixed end 201 of the lock body 200. The free end 202 can be movably inserted into the lock head 100. In this embodiment, there are insertion holes 104 on the housing and the core housing for the free end to insert. It should be noted that a lock brake portion 1021 for locking the free end 202 of the lock body 200 is provided on the lock core 102. The free end 202 of the lock body 200 has a bayonet 2021. After the free end 202 of the lock body 200 is inserted into the lock head 100, the lock core 102 is rotated to make the lock brake portion 1021 of the lock core 102 form a snap-fit with the bayonet of the free end 202 of the lock body 200. In this embodiment, the lock brake portion 1021 is at least one notch provided on the surface of the lock core 102. A channel for the free end 202 of the lock body 200 to move is formed between the position of the lock core 102 at the notch and the inner wall of the space where it is located. When the lock core 102 is in the unlocked state, this channel allows the free end 202 of the lock body 200 to be freely inserted and removed. When the lock core 102 is in the locked state, the distance between the channels is reduced to form a snap portion to catch the bayonet 2021 of the free end 202 of the lock body 200. In this embodiment, there are only three parts in the lock head 100, namely the lock core 102, the core housing 103 and the housing 101. Compared with the traditional folding lock structure, it is simpler and has greater advantages in terms of production cost and assembly cost. In this embodiment, the lock brake portion is provided at the end of the lock core where the key is inserted, and the inside of the lock brake portion is a hollow structure, and the key is inserted from here.

[0023] In this embodiment, the bayonet 2021 is integrally C-shaped. The lock brake portion 1021 is provided with two notches. The two planes formed by the two notches are parallel to each other. The width of the part between the two notches is smaller than the width of the mouth of the bayonet 2021. The diameter of the lock core 102 at the position of the lock brake portion 1021 is smaller than the inner diameter of the bayonet 2021 and larger than the width of the mouth of the bayonet 2021. In this way, the lock core 102 can be locked to the free end 202 by rotating 90 degrees.

[0024] In this embodiment, a limiting mechanism for preventing axial movement of the lock core 102 is provided between the lock core 102 and the core housing 103. In this embodiment, the limiting mechanism includes a long groove 1022 provided on the outer surface of the lock core 102, and a limiting member 400 extending into the long groove 1022 of the lock core 102 is provided on the corresponding core housing 103. The cooperation between the long groove 1022 and the limiting member 400 enables the lock core 102 to move only along the length direction of the long groove 1022. The setting of the long groove 1022 not only limits the movement direction of the lock core 102, but also limits the rotation angle of the lock core 102. In this embodiment, the long groove 1022 is exactly one-fourth of the outer surface of the lock core 102, that is, the lock core 102 can rotate 90 degrees, so as to accurately judge the size of the channel into which the free end 202 of the lock body 200 is inserted, facilitating the user to lock and unlock the door.
