Abstract

The inside that key cover has the headgear and tail sleeve for being tubular, headgear is provided with an axis, and an outside face is provided with multiple openings；Middle the tip of the axis is connected with key, middle part be arranged with it is multiple can be equipped with a breach on each rotating disk around the rotating disk of middle shaft rotation, each rotating disk some exposed in the outside of headgear by an opening；The port of tail sleeve is inwardly sequentially provided with multiple sawtooth.The utility model can allow the key will not arbitrarily to be used by stranger, and the person and property safety of protection user, simple and fast are practical, be easy to promote.

Description

Key cover

Technical field

The utility model is related to a kind of key cover, particularly a kind of key cover with coded lock.

Background technology

For unlocking during key, but key is usually in itself what is do not locked, so when key is stolen or found by people, It is possible to threaten the property even personal safety of user.Although also having coded lock now, do not popularize also, it is upper Age or the people having a bad memory use more inconvenient.

Utility model content

To solve the above problems, the utility model provides a kind of for the key cover with coded lock.

The utility model solves the technical scheme that its technical problem used：Key cover have be tubular headgear and Tail sleeve, the inside of the headgear is provided with an axis, and an outside face is provided with multiple openings；The middle the tip of the axis connection There is key, middle part is arranged with multiple and a breach can be equipped with each described rotating disk around the rotating disk of the middle shaft rotation, Each described rotating disk some by one it is described opening expose in the outside of the headgear；The port of the tail sleeve to Inside it is sequentially provided with multiple sawtooth.

The quantity of the opening, the rotating disk and multiple sawtooth is equal and be more than three, the adjacent rotating disk Between and the distance between the adjacent sawtooth it is equal.

The part of the side of the rotating disk is provided with multiple different numerals, and the maximum angle that the rotating disk can rotate is 180°。

The beneficial effects of the utility model are：Can allow the key will not arbitrarily to be used by stranger, protect the person of user And property safety, simple and fast is practical, is easy to promote.

Brief description of the drawings

Fig. 1 is the outward appearance front view of key cover；

Fig. 2 is the cut-away view of key cover；

Fig. 3 is the internal cross section figure of key cover.

In figure：Headgear 1, tail sleeve 2, rotating disk 3, axis 11, opening 12, sawtooth 21, breach 31, numeral 32.

Specific embodiment

To make the technical solution of the utility model become more apparent, specific embodiment is new to this practicality below in conjunction with the accompanying drawings Type is described further.

As shown in Figure 1-2, key cover has the headgear 1 and tail sleeve 2 for being tubular, and the inside of headgear 1 is provided with an axis 11, an outside face is provided with multiple openings 12；The end of axis 11 is connected with key, and middle part is arranged with multiple can be around Axis 11 rotation rotating disk 3, a breach 31 is equipped with each rotating disk 3, each rotating disk 3 it is equal some by one be open 12 expose in the outside of headgear 1；The port of tail sleeve 2 is inwardly sequentially provided with multiple sawtooth 21.

Opening 12, rotating disk 3 is equal with the quantity of multiple sawtooth 21 and be more than three, between adjacent rotating disk 3 and adjacent The distance between sawtooth 21 it is equal, the part of the side of rotating disk 3 is provided with multiple different numerals 32.

As shown in figure 3, when using key cover, all rotating disks 3 first are adjusted into certain position, institute jagged 31 is respectively positioned on , then be inserted into tail sleeve 2 in headgear 1 by certain position, and sawtooth 31 just passes through from breach 31, and now rotating disk 3 is exposed at opening Numeral 32 outside 21 is password, rotates rotating disk and upsets password, you can pins key, if pulling tail sleeve 2, sawtooth 21 can quilt Rotating disk 3 is blocked.

When needing to take out key, rotating disk 3 is rotated until correct password figure 32 is exposed to outside opening 21, it is now all to lack Mouth 31 is respectively positioned on desired position, pulls tail sleeve 2, and sawtooth 31 just passes through from breach 31, can be taken off tail sleeve 2, it is possible to use Key.

The maximum angle that rotating disk 3 can rotate is only 180 °, and breach 31 will not go to the position of opening 21, in order to avoid quilt It was found that the position of breach 31, understands accordingly, it is only necessary to set numeral at the half position of the side of rotating disk 3.

Specific embodiment of the present utility model is the foregoing is only, but protection domain of the present utility model is not limited to This, any one skilled in the art in the technical scope that the utility model is disclosed, can readily occur in change or The technical scheme of replacement, should all cover within protection domain of the present utility model.
