Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hardware, in particular to a key ring. BACKGROUND

[0002] In daily life, key rings are commonly used tools for people to carry and manage keys, and are widely used in individuals, families and various public places. It not only plays the role of conveniently carrying keys, but also has a decorative function through different designs and shapes, becoming a kind of personalized small object. In daily life and work scenes, many people are used to hanging key rings on their waists, and such a carrying method is convenient and can use keys at any time. Especially for people who often go out, engage in physical labor, or frequently need to use keys in work, such as express delivery personnel, warehouse managers, construction workers, etc., it is a very common practice to hang key rings on the waist. It is not only convenient and fast, but also can avoid the trouble of searching for keys from pockets or bags due to busy hands. For example, the Chinese patent document with publication number CN108125327B discloses a key ring, which comprises a shell, a clasp and a pendant. The shell is provided with a push button, and the bottom of the push button is provided with a sliding block. The sliding block is placed in the shell, and the push button slides axially on the shell. The clasp comprises a fixed arm and a movable arm, and the movable arm is hingedly connected with the shell. The movable arm comprises a closed end and a driving end. The sliding block has a first state in which the driving end is pushed to make the closed end away from the fixed arm, a second state in which the driving end is pushed to make the closed end close to the fixed arm, and a third state in which the driving end is stopped to make the closed end and the fixed arm fit and lock. The driving end is "J" shaped, which is composed of a front pushing part and a rear pushing part. The front pushing part is long at one end, and the rear pushing part is a round hook part. The rear pushing part is at the rear end of the sliding block in the first state, and is in contact with the side wall of the sliding block in the third state. The fixed arm is integrally formed with the shell.

[0003] However, the existing key ring has the following deficiencies in the actual use process: when the waist of a person is frequently active, whether it is bending, turning, squatting, or engaging in more intense physical labor, the push button on the key ring at the waist is prone to collision or extrusion with surrounding objects. For example, when passing through a narrow space, the push button is extruded by walls, door frames, etc., and when carrying heavy objects, the waistband will also extrude the push button on the key ring, causing the key ring to be in an open state, thereby causing the key ring to fall. This will cause the key to be lost, causing economic losses to the user in reconfiguring the key and replacing the lock. In view of this, the key ring of the present application is proposed.

Furthermore, the buckle rod 21 tends to have a "7"-shaped structure, with one end of the buckle rod 21 positioned on the inner liner block 12, and the other end facing the side of the groove 121 in the inner liner block 12. The locking rod 22 tends to have an "L"-shaped structure, with one end of the locking rod 22 located within the groove 121 and rotatably connected to the inner wall of the groove 121. The other end of the locking rod 22 engages with the end of the buckle rod 21 furthest from the inner liner block 12, so that the locking rod 22 and the buckle rod 21 together form a closed-loop hook structure.

[0042] As Figure 3 , Figures 6-7 , Figure 13 shown, in an embodiment, the clamping piece 24 comprises a connecting rod 241 and a clamping block 242, two ends of the connecting rod 241 are respectively rotationally connected with the lock rod 22 and the clamping block 242, the clamping block 242 is slidingly arranged on the buckle seat 10, and the end of the clamping block 242 away from the connecting rod 241 is clamped with the inclined slot 231.

[0043] It should be noted that the connecting rod 241 is located in the groove 121, and one end of the connecting rod 241 is rotationally connected with the corner position of the lock rod 22, so that the connecting rod 241 drives the lock rod 22 to be clamped with the buckle rod 21 away from the inner lining block 12. Further, the inner lining block 12 is also provided with a long hole 122, the long hole 122 is located on the two inner side walls of the inner groove 112, the long hole 122 is arranged along the vertical upward direction, and the two long holes 122 are aligned with each other. The two side surfaces of the clamping block 242 are clamped with the two long holes 122, so that the clamping block 242 can slide up and down relative to the inner lining block 12. Further, one end of the clamping block 242 is rotationally connected with the end of the connecting rod 241 away from the lock rod 22, when the clamping block 242 slides upward, the clamping block 242 drives the connecting rod 241 to push the lock rod 22, so that the end of the lock rod 22 away from the inner lining block 12 is away from the buckle rod 21, thereby making the hook formed by the lock rod 22 and the buckle rod 21 in a closed loop state in an open state, when the clamping block 242 slides downward, the end of the lock rod 22 away from the inner lining block 12 is clamped with the buckle rod 21 to form a closed hook structure.

[0044] It should be noted that the guide hole 111 is provided on the circular block 11, the guide hole 111 is consistent with the opening direction of the long hole 122, the guide hole 111 extends from the outer side of the circular block 11 to the inner groove 112, when the inner lining block 12 is embedded on the circular block 11, the guide hole 111 is communicated with the recess 121.
