Abstract

The utility model discloses a key ring which comprises a hook seat, one end of the hook seat is connected with a key ring connecting device, an arc-shaped cant hook extends from one side of the other end of the hook seat, a free end of the cant hook is held against a closed block hook to form a closed ring, the closed block hook is arranged in an inner cavity of a hook seat sandwich, the middle of the inner cavity is provided with a rotating pole crossing two side walls of the cavity body, a round hole of the closed block hook is sleeved with the rotating pole, a pull rod is arranged at one end away from the free end of the cant hook; the rotating pole is also sleeved with a torsion spring, one end of the torsion spring is held against the hook seat, the other end of the torsion spring is held against the closed block hook; the spring plate key ring is designed into a sealed ring formed by the arc-shaped hook lever and a spring plate, can be hooked on a belt conveniently, has high insurance performance and wide application range; the spring plate is adopted to extend from the T-shaped point of the T-shaped locating frame and be held against the arc-shaped hook lever, which reduces harmful torque produced by the spring and extends the service life.

Description

A kind of key chain

Technical field

The utility model relates to daily living article, is specifically related to a kind of key chain.

Background technology

At present, the key chain that uses on the market, employing be not other buckling on belt, if do not have belt or other strip article, such key chain just can't conveniently use, range of application is narrow; And adopt the key chain of cingulum mode, employing be that the mode of spring is tightly buckled, control the switching of key chain by pushing force, such pushing force mode is easy to generate bigger torque, influences the life-span of key chain.

The utility model content

The purpose of this utility model is: it is the cingulum mode that a kind of employing is provided, torque spring, it is wide to use the orientation, the key chain of long service life.

The technical scheme that the utility model provides is as follows: a kind of key chain, comprise a hook base, hook base one end is connected with a key chain jockey, one side of the other end of hook base is stretched out the shank of an arc, the free end of shank is against there being a sealing stop hook to form a closed-loop, the sealing stop hook is installed in the inner chamber of hook base interlayer, the inner chamber middle part is provided with a Rotational Cylindrical across the cavity two side, the circular hole socket of Rotational Cylindrical and sealing stop hook, described sealing stop hook is being provided with a tommy bar away from shank free end one end; Described Rotational Cylindrical also is socketed with a torque spring, and torque spring one end is resisted against on the hook base, and the other end is resisted against on the sealing stop hook.

As an improvement of the present utility model, described key chain jockey comprises and stretches out hook base, has the card post of big dop, and the card column sleeve is connected to the ellipse boss that a middle part is provided with circular hole, and two lateral walls of boss are connected with a disciform key chain circle.

The utlity model has following advantage: adopted arc hook and sealing stop hook to form the design of a sealing ring, can buckle easily on waistband, the safety performance height can not break off relations, and range of application is big; Adopt torque spring close encapsulation ring automatically, reduce harmful torsion that spring produces, prolonged service life.

The specific embodiment

Below in conjunction with accompanying drawing concrete embodiment is illustrated:

As shown in Figure 1, a kind of key chain comprises a hook base 1, hook base 1 one ends stretch out hook base 1, the card post 15 that has big dop 16, card post 15 is socketed with the ellipse boss 4 that a middle part is provided with circular hole, and two lateral walls of boss 4 are connected with a disciform key chain circle 5; One side of hook base 1 an other end is stretched out the shank 2 of an arc, the free end of shank 2 is against there being a sealing stop hook 3 to form a closed-loop, sealing stop hook 3 is installed in the inner chamber 11 of hook base 1 interlayer, inner chamber 11 middle parts are provided with a Rotational Cylindrical 13 across the cavity two side, the circular hole socket of Rotational Cylindrical 13 and sealing stop hook 3, it is characterized in that: described sealing stop hook 3 is being provided with a tommy bar 31 away from shank 2 free ends one end; Described Rotational Cylindrical 13 also is socketed with a torque spring 14, and torque spring 14 1 ends are resisted against on the hook base 1, and the other end is resisted against on the sealing stop hook 3.

Above embodiment is explanation rather than restriction the utility model just, can be ellipse, also can be square, cylindrical, polygon as: boss 4; Shank 2 can be an arc, also can be square, semicircle or the like ..., of this sort conversion all falls within the protection domain of the present utility model.
