Abstract

The utility model discloses a spring plate key ring, comprising a rectangular cylindrical key ring circle, an arc-shaped cylindrical hook lever extends from the middle of a long edge of the rectangular ring circle and forms a stereo J-shaped buckle body with the ring circle, a T-shaped locating frame is fixed on a T-shaped position formed by the ring circle and the hook lever, two locating plates extend from the side profile of the T-shaped locating frame to form a circular frame body, a spring plate extends from a T-shaped point of the T-shaped locating frame, is through the circular frame body and is held against a free end of the hook lever to form a sealed ring; the spring plate key ring is designed as 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 shell fragment key chain

Technical field

The utility model relates to daily living article, is specifically related to a kind of shell fragment 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, and adopt the push strut of closing on spring roof pressure one direction, use pushing force to control the switching of key chain, such pushing force mode makes and produces bigger torque on the push strut, influences the life-span of key chain;

The utility model content

The purpose of this utility model is: it is the locking-type key chain of spring leaf mode, applied range, long service life that a kind of employing is provided.

The technical scheme that the utility model provides is as follows: a kind of shell fragment key chain, comprise a rectangular cylinder key chain circle, stretch out the cylinder shank of an arc at middle part, the long limit of rectangle button circle, it is characterized in that: shank and button circle form the J type button of a solid, T type fixed-site in button circle and shank formation is connected with a T type locating rack, the side outline limit of T type locating rack is stretched out two spacers and is formed a ring-like support body, stretch out a spring leaf from the T type point of described T type locating rack and pass the free end that described annular frame is resisted against shank, form a sealing ring.

The utlity model has following advantage: adopted arc shank and spring leaf 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 spring leaf to stretch out and be resisted against the arc shank, reduce harmful torsion that spring produces, prolonged service life from the T type point of T shape frame.

Fig. 3 is the side view of Fig. 1;

The specific embodiment

Below in conjunction with accompanying drawing concrete embodiment is illustrated:

As Fig. 1, Fig. 2, shown in Figure 3, a kind of shell fragment key chain, comprise a rectangular cylinder key chain circle 1, stretch out the cylinder shank 2 of an arc at middle part, rectangle button circle 1 long limit, shank 2 and button circle 1 form the J type button of a solid, T type fixed-site in button circle 1 and shank 2 formation is connected with a T type locating rack 3, the side outline limit of T type locating rack is stretched out two spacers 31 and is formed a ring-like support body 4, stretch out a spring leaf 5 from the T type point of described T type locating rack 3 and pass the free end that described annular frame 4 is resisted against shank 2, form a sealing ring.

Above embodiment is explanation rather than restriction the utility model just, can be rectangle, also can be oval, circular, polygon as: key chain circle 1; Button circle 1 can be a cylinder, also can be oval cylinder, square cylinder, polygonal cylinder; 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.
