Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a chain lock. Background Technology

[0002] Chain locks are primarily used to secure items to fixed objects to prevent them from being taken away arbitrarily. For example, they can be used to lock bicycles or carts to railings or posts. A typical chain lock consists of a chain with interlocking locks at both ends. These locks are usually double-lock or padlocks, preventing the secured items from moving freely and being stolen.

[0003] Existing chain locks have a complex structure and numerous parts, making it difficult to process and assemble each component. This makes the unlocking and unlocking process cumbersome and inconvenient for users. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a chain lock that addresses the above-mentioned defects of the prior art. When in use, the lock cylinder is turned by the key, which drives the dial to rotate to unlock. The overall structure is relatively simple, requires fewer parts, is easy to assemble, has a low cost, and is simple and convenient for users to operate.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A chain lock includes a housing, a latch, a lock head, a lock shell, a lock cylinder, a detonator, and a spring. The lock shell is installed inside the housing. The lock cylinder and the detonator are rotatably installed inside the lock shell. The lock head is fixedly connected to the lock shell. One end of the latch passes through the housing and the lock shell in sequence and engages with the detonator. The detonator engages with the lock cylinder. One end of the lock head abuts against the detonator through a spring. The other ends of the lock head and the latch are each provided with a chain connection through hole.

[0006] Preferably, the housing includes a first housing and a second housing arranged symmetrically to each other, and the first housing and the second housing are snap-fitted together.

[0007] Preferably, decorative pieces are provided on both the first and second outer shells.

[0008] Preferably, the dial has a first arc-shaped groove, and one side of the locking nozzle has a second arc-shaped groove that matches the first arc-shaped groove.

[0009] Preferably, a lock mouth shell and a decorative ring are sequentially fitted onto the outer side of the lock mouth.

[0010] Preferably, the lock cylinder has a keyhole for inserting a key.

[0011] The chain lock provided by this utility model, using the above technical solution, has the following beneficial effects: the lock shell is installed inside the outer shell, the lock cylinder and the dial are rotatably installed inside the lock shell, the lock head is fixedly connected to the lock shell, one end of the lock mouth passes through the outer shell and the lock shell in sequence and engages with the dial, the dial engages with the lock cylinder, one end of the lock head abuts against the dial through a spring, and the other end of the lock head and the lock mouth are provided with chain connection through holes. When in use, the lock can be unlocked by rotating the lock cylinder with the key to drive the dial to rotate. The overall structure is relatively simple, requires fewer parts, is easy to assemble, has a low cost, is relatively simple to operate, and is more convenient to use. Attached Figure Description

Detailed Implementation

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0016] like Figure 1-3 As shown, the chain lock includes a housing, a latch 3, a lock head 4, a lock shell 5, a lock cylinder 6, a latch 7, and a spring 8. The lock shell 5 is installed inside the housing. The lock cylinder 6 and the latch 7 are both rotatably installed inside the lock shell 5. The lock head 4 is fixedly connected to the lock shell 5. One end of the latch 3 passes through the housing and the lock shell 5 in sequence and engages with the latch 7. The latch 7 engages with the lock cylinder 6. One end of the lock head 4 abuts against the latch 7 via the spring 8. The other ends of both the lock head 4 and the latch 3 have chain connection through holes 9. It is understood that the lock head 4 and the latch 3 are arranged perpendicularly to each other. In practical applications, the lock head 4 is connected to the latch 3 via a chain.

[0017] Specifically, the outer casing includes a first outer casing 1 and a second outer casing 2 arranged symmetrically to each other. The first outer casing 1 and the second outer casing 2 are snap-fitted together. Both the first outer casing 1 and the second outer casing 2 are provided with decorative pieces 10. The dial 7 has a first arc-shaped groove 11. One end of the lock cylinder 3 has a second arc-shaped groove 12 that matches the first arc-shaped groove 11. The outer side of the lock cylinder 3 is fitted with a lock cylinder outer casing 13 and a decorative ring 14 in sequence. The lock cylinder 6 has a keyhole 15 for inserting a key 16. It can be understood that by rotating the lock cylinder 6, the dial 7 is rotated, causing the end of the lock cylinder 3 to disengage from or engage with the dial 7, thereby achieving unlocking or locking.

[0018] Understandably, this utility model has a reasonable design and unique structure. When in use, the key 16 rotates the lock cylinder 6, which drives the dial 7 to rotate, thus unlocking the lock. The overall structure is relatively simple, requires fewer parts, is easy to assemble, has a low cost, and is easy for users to operate and use.

[0019] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
