Description

a keychain

technical field

The utility model relates to daily necessities, in particular to a key chain.

Background technique

At present, the keychains used in the market adopt a buckle attached to the belt. If there is no belt or other strips, such a keychain cannot be used conveniently, and its application range is narrow; The buckle is tightly buckled by a spring, and the opening and closing of the keychain is controlled by pushing force. Such a pushing force method is likely to generate a large torque force and affect the life of the keychain.

Utility model content

The purpose of the utility model is to provide a keychain which adopts buckle belt and torsion spring, has wide application orientation and long service life.

The technical scheme provided by the utility model is as follows: a keychain, including a hook seat, one end of the hook seat is connected with a keychain connecting device, and an arc-shaped hook bar protrudes from the other end of the hook seat, and the free end of the hook bar A closed retaining hook forms a closed ring against a closed retaining hook. The closed retaining hook is installed in the inner cavity of the interlayer of the hook seat. In the middle of the inner cavity, there is a rotating column spanning the two side walls of the cavity. The rotating column and the round hole of the closing retaining hook Socketed, the closed retaining hook is provided with a pull lever at the end far away from the free end of the hook rod; the rotating column is also sleeved with a torsion spring, one end of the torsion spring leans against the hook seat, and the other end leans against the closed retaining hook .

As an improvement of the present utility model, the key chain connecting device includes a clamping column with a large chuck that protrudes from the hook seat. The clamping column is sleeved with an elliptical boss with a round hole in the middle. An elliptical key ring is connected to the two outer walls.

The utility model has the following advantages: the arc-shaped hook and the sealing retaining hook are adopted to form a sealing ring design, which can be conveniently hung on the belt, has high safety performance and will not be unhooked, and has a wide application range; the torsion spring is used to automatically seal and seal The ring reduces the harmful torsion generated by the spring and prolongs the service life.

Detailed ways

Below in conjunction with accompanying drawing, specific embodiment is described:

As shown in Figure 1, a key chain includes a hook seat 1, one end of the hook seat 1 protrudes from the hook seat 1, and a post 15 with a large chuck 16, and the post 15 is sleeved with a round hole in the middle. The elliptical boss 4, the two outer walls of the boss 4 are connected with an elliptical key ring 5; the other end of the hook seat 1 stretches out an arc-shaped hook bar 2, and the free end of the hook bar 2 leans against There is a closed retaining hook 3 to form a closed ring, and the closed retaining hook 3 is installed in the inner chamber 11 of the hook seat 1 interlayer. The round hole socket of the retaining hook 3 is characterized in that: the closed retaining hook 3 is provided with a trigger lever 31 at one end far away from the free end of the hook rod 2; It leans against the hook seat 1, and the other end leans against the closed retaining hook 3.

The above embodiments only illustrate rather than limit the utility model, such as: the boss 4 can be oval, square, cylindrical, polygonal; the hook bar 2 can be arc, square, semicircle, etc. Etc..., similar transformations all fall within the protection scope of the present utility model.
