Description

A kind of key chain

The utility model relates to a kind of key chain, particularly relates to a kind of key chain of being convenient to put into and take out key.

In the prior art, general key chain adopts the structure of rigidity key bow usually, and this structure is not easy to take out and puts into key, uses very inconveniently, and the shape of the key chain of rigidity key bow is single, outmoded, and is very not attractive in appearance.

The purpose of this utility model is to avoid weak point of the prior art and provides a kind of simple in structure, and is easy to use, be convenient to put into and take out key, a shape and a great variety of models, novelty, key chain attractive in appearance.

The purpose of this utility model can reach by following measure: key chain includes the spoon bob and key bow constitutes, key bow is plasticity or elasticity key bow, spoon is provided with lock adjustment mechanism in weighing down, the key bow jack that the key bow two ends are weighed down by spoon inserts in spoon lock adjustment hole of weighing down, and is fixed by the lock adjustment mechanism that is arranged in the lock adjustment hole.Make thus simple in structure, easy to use, be convenient to put into and take out key, a shape and a great variety of models, novelty, key chain attractive in appearance.

The purpose of this utility model can also reach by following measure: the lock adjustment mechanism of key chain constitutes by regulating ball and adjusting screw(rod), adjusting screw(rod) is loaded in the spoon bob and occupy the lock adjustment aperture to vertical line, regulate ball and be loaded on the adjusting screw(rod), compress or unclamp key bow along the adjusting screw(rod) lifting.This structure is flexible and convenient to use.

The utility model is described in further detail to utilize accompanying drawing:

Fig. 1 is the structural representation of a kind of key chain of the present utility model;

Fig. 2 is the structural representation of a kind of key chain of the present utility model;

Fig. 3 is the structural representation of a kind of key chain of the present utility model.

In Fig. 1, Fig. 2 and the of the present utility model a kind of key chain shown in Figure 3, include that spoon weighs down 1, key bow 2, regulate ball 3, adjusting screw(rod) 4, spoon and weigh down lock adjustment hole 5 in 1 and key bow jack 6 and positioning ring groove 7 and constitute.

The utility model is described in further detail with the following Examples:

A kind of key chain of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 3, include spoon bob 1 and key bow 2 formations, key bow 2 is plasticity or elasticity key bow, spoon weighs down in 1 and is provided with lock adjustment mechanism, the key bow jack 6 that key bow 2 two ends are passed through in the spoon bob 1 inserts in the lock adjustment hole 5 of spoon bob 1, and is fixed by the lock adjustment mechanism that is arranged in the lock adjustment hole 5.Lock adjustment mechanism can constitute by regulating ball 3 and adjusting screw(rod) 4, and adjusting screw(rod) 4 is loaded on spoon and weighs down in 1 and occupy radially vertical line of lock adjustment hole 5, regulates ball 3 and is loaded on the adjusting screw(rod) 4, compresses or unclamps key bow 2 along adjusting screw(rod) 4 liftings.

A kind of key chain of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 3 can be provided with positioning ring groove 7 on its lock adjustment hole 5.So that key bow 2 is axially located in lock adjustment hole 5.

A kind of key chain of the present utility model as shown in Figure 2, it regulates the thickness of diameter 〉=spoon bob 1 of ball 3.So that operation.

A kind of key chain of the present utility model, its key bow 2 can be flexible plastic bar key bows.Its key bow 2 can also be a finer wire cable key bow.

The utility model compared with prior art has simple in structure, and is easy to use, be convenient to put into and take out key, Shape and a great variety of models, novelty, the characteristics such as attractive in appearance.
