The utility model solves the technical scheme that its technical problem adopts:

There is key chain that is flexible and illumination functions, it is characterized in that: there is housing, the wire wheel axis set firmly in housing wears wire wheel axis hole set on the axis of wire-crossing wheel, line wheel is arranged with connecting line, connecting line stretches out from the through hole that the below of housing is offered, and connecting line end is connected with key-ring hanging head; The side of line wheel is provided with wind spring, and one end of wind spring is fixedly connected with on online wheel, and the other end of wind spring is fixedly connected on wire wheel axis;

Housing is installed with LED lamp bead, and LED lamp bead is connected with battery accommodating in housing, and surface of shell is provided with the switch of the circuit that can switch on or off LED lamp bead and battery;

Housing there is a round hook with opening, a hook closure bar be hinged on housing can close the opening of hook, hook closure bar has hollow cavity, a spring is equipped with in chamber, spring top supports one end of a limited block, on the V-type confined planes that the other end contact of limited block is set on housing.

Usefulness of the present utility model is:

The utility model can pull out key-ring hanging head, unclamps after using key, key-ring hanging head meeting automatic drawing back; The utility model can also provide illumination functions; Hook enclosed construction of the present utility model is simple and reliable, can automatically rebound after opening.

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is three-dimensional exploded view of the present utility model;

Fig. 2 is the three-dimensional exploded view at the utility model hook position;

Fig. 3 is the figure at the utility model hook position;

Detailed description of the invention

As shown in Figure 1, the utility model has protecgulum 1, bonnet 10, is main body 5 in the middle of protecgulum 1 and bonnet 10, and protecgulum 1 and main body 5 fasten with buckle structure, and main body 5 and bonnet 10 bond with ultrasonic bonds technique.Protecgulum 1, bonnet 10, main body 5 just form a housing.

The middle part of bonnet 10 has a wire wheel axis 81, and wire wheel axis 81 wears wire wheel axis hole 80 set on wire-crossing wheel 8 axis, thus line wheel 8 is set on wire wheel axis 81 rotationally, and line wheel 8 is between bonnet 10 and main body 5.The side of line wheel 8 has wind spring containing groove, and be equipped with wind spring 82 in wind spring containing groove, on the affixed online wheel 8 in one end of wind spring 82, the other end of wind spring 82 is fixed on wire wheel axis 81.Line wheel 8 is arranged with connecting line 91, and the through hole that connecting line 91 is offered below bonnet 10 passes, and connecting line 91 end is connected with the key-ring hanging head 9 hanging key.

As shown in Figure 4, can pull out key-ring hanging head 9, at this moment connecting line 91 is drawn out, and line wheel 8 rotates, wind spring 82 is out of shape, and after using key, decontrol key-ring hanging head 9, wind spring 82 is replied, 8 backwards rotation taken turns by line, and connecting line 91 is wound around on online wheel 8 and regains, and key-ring hanging head 9 is regained.

Space between main body 5 and protecgulum 1 is installed with button cell 3, is installed with a high pin white LED lamp pearl 7 in protecgulum 1 and the through hole set by main body 5 lower end, and button cell 3 connects LED lamp bead 7 and powers to LED lamp bead 7.Be provided with a slide switch 2 in the through hole of the upper surface of protecgulum 1, slide switch 2 connects the circuit of LED lamp bead 7 and battery 3 with prior art, and can switch on or off the circuit of LED lamp bead 7 and battery 3.

As shown in Figure 4, press slide switch 2, can light or close LED lamp bead 7, thus obtain illuminating effect.

The top of main body 5 has the round hook 51 that has opening, and as shown in Figure 2 and Figure 3, through a hinge 62 in hinge hole 61 set in hinge hole 52 set in main body 5 and a hook closure bar 6, thus hook closure bar 6 is hinged in main body 5.Main body 5 has a V-type confined planes 53.Hook closure bar 6 has the inner chamber of hollow, and be equipped with a spring 63 in chamber, one end of a spring 63 contact limited block 64, the other end contact of limited block 64 is on V-type confined planes 53.

As shown in Figure 2, Figure 3, Figure 4, generally promote hook closure bar 6 within round hook 51 during use, thus cause breach can hang over trousers to buckle, at this moment, hook closure bar 6 is rotated counterclockwise, limited block 64 moving upward on that face 531 within round hook 51 at V-type confined planes 53, thus limited block 64 is extruded and Compress Spring 63 by chamber.When decontroling hook closure bar 6, spring 63 resets, limited block 64 moving downwards on that face 531 within round hook 51 at V-type confined planes 53, hook closure bar 6 turns clockwise, until limited block 64 touch V-type confined planes 53 towards round hook 51 outside that face 532, at this moment limited block 64 is no longer moved by withstanding, and links up with closure bar 6 and round and link up with 51 and form a closed circle.
