[0001] This utility model relates to the field of keychain processing technology, and in particular to a sliding self-locking anti-loss keychain. Background Technology

[0002] As an indispensable item in daily life, the security of carrying and keeping keys has always been a focus of people's attention. In order to make it easier for people to carry and keep keys, they usually use keychains to carry and keep keys.

[0003] People typically hang their keys on a keychain and carry the keychain with them. When they need to use the keys, they remove the keychain. However, since the keychain must be removed before the keys can be used, elderly people may forget their keys after removing them, leading to key loss. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sliding self-locking anti-loss keychain, which aims to improve the problem of forgetting the key after taking it off for use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sliding self-locking anti-loss keychain, comprising a housing, a spring-loaded mechanism installed on the inner wall of the housing, a connecting post installed on one side of the spring-loaded mechanism, a limit post fixedly connected to the outer wall of the connecting post, a threaded groove provided on the outer wall of the connecting post, a rope provided on the outer wall of the threaded groove, and a connecting block fixedly connected to one end of the rope.

[0006] According to the above technical solution: a spring is installed inside the housing, the spring is connected to a connecting post, a limiting block is connected to the connecting post, a threaded groove is provided, a rope is connected to the connecting block, and the connecting block is connected to the rope. The connecting post is rotated by the stretching of the rope, and the rope can be automatically contracted by the deformation force of the spring, so that the key can be stretched and used. After use, it can be automatically contracted to avoid forgetting or losing the key.

[0007] Preferably, a connecting ring is installed at one end of the connecting block, and a connecting ring is installed on one side of the connecting ring.

[0008] Preferably, a connecting rod is fixedly connected to one end of the housing, a fixing post is fixedly connected to one end of the connecting rod, a hook is installed on the outer wall of the connecting rod, and a spring-loaded component is provided inside the hook.

[0009] Preferably, the rebound assembly includes a fixing rod, one side of which is slidably connected to the inside of the hook, one end of which is fixedly connected to a damper, a first spring is installed on the outer wall of the damper, and one end of the damper is fixedly connected to the inside of the hook.

[0010] Preferably, a limiting block is fixedly connected to one side of the fixing rod, and a fixing block is fixedly connected to one end of the limiting block.

[0011] Preferably, one side of the first spring is mounted on one end of the fixed rod.

[0012] Preferably, a first groove is provided on one side of the hook, and one side of the limiting block is slidably connected to the inner wall of the first groove.

[0013] Preferably, the bottom end of the fixing block is slidably connected to one side of the hook.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the connection between the housing and the spring is such that the spring and the rope are connected by a connecting post. When the rope is pulled, the connecting post rotates, and the rotation of the connecting post causes the spring to deform. When the rope is released, the deformation force of the spring can cause the rope to automatically retract, achieving the effect of automatic recycling and avoiding the forgetting or loss of the key due to removing the key.

[0016] 2. In this utility model, the damper and the first spring are connected to the fixed rod, and the limiting block connects the fixed block and the fixed rod. When the fixed block slides down, it drives the fixed rod to press down on the first spring. When the hand is released, the first spring will drive the fixed rod to rebound, which facilitates the opening and closing of the hook and achieves the effect of simplifying the opening steps and facilitating the hanging of the key ring.
