CN203538524U - Key chain capable of preventing swinging of key - Google Patents

Abstract

The utility model relates to a key chain capable of preventing swinging of a key. The key chain comprises retaining sheets and a cylinder, wherein each retaining sheet is a rectangle with a round angle; a seam is formed at the middle part of the cylinder to form a connecting rod with the seam; a spring and the connecting rod with the seam are fixed in the retaining sheets; the spring is arranged at the upper end, and the connecting rod with the seam is arranged at the lower end. The distance between the spring and the connecting rod with the seam is slightly smaller than the length of a common key, the key is hung on the connecting rod through the seam of the connecting rod, the head of the key is clamped in the seam of the spring, and then the key is fixed between the two retaining sheets. The key chain has the advantages that the hanging accommodation and key fixing functions are realized, a small hole in the tail part of the key can be hung and accommodated onto the key chain through the seam of the connecting rod, then the head of the key is inserted into the seam of the key, and the key can be fixed on the key chain, so the key does not swing, thereby improving the safety of the key chain. The key chain has the characteristics of simple structure, and convenience and practicality.

Description

A kind of key chain that prevents that key from rocking

Technical field

The utility model belongs to commodity technical field, particularly relates to a kind of key chain that prevents that key from rocking.

Background technology

At present, known key chain is comprised of annulus and hasp.Such key chain in use, because key is unfixing, rock, and loses by generation, and the security of key chain is reduced.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of key chain that prevents that key from rocking, the problem of in use easily rocking to solve key.

The utility model solves the technical scheme that its technical problem adopts: a kind of key chain that prevents that key from rocking is provided, comprise catch, spring and connecting rod with seam, described catch is that a flat board and four angles are arc transition, two catch are arranged in opposite directions, two catch upper ends are provided with spring between relative position, and two catch lower ends are connected with a connecting rod with seam between relative position.

Distance between described spring and connecting rod with seam is slightly less than the length of normal key, and key is fixed between spring and connecting rod with seam.

On described connecting rod, hang key.

Beneficial effect

The utlity model has to hang and take in and the fixing function of key, key tail aperture can be accommodated on key chain in the crack suspension by connecting rod, then key head is inserted to gapping of spring, make key can be fixed on key chain, do not produce and rock, improve the security of key chain.The utility model also has simple in structure, convenient and practical feature.

Accompanying drawing explanation

Fig. 1 is the utility model general assembly schematic diagram.
