Description

Key easy to identify

The utility model relates to key, is a kind of key of easy identification.

Key is indispensable article during people live, no matter enter, open cabinet, open drawer, so long as with the occasion of lock, all to use key to open, and along with the expansion of people's scope of activities, with key more and more, what have has a big string key.Existing various key, all include a key Handheld Division and a bolt tooth open portion in its structure, the key Handheld Division generally all is that some are rounded, the smooth flat body of triangle, prismatic or shape such as trapezoidal, on this plane body, be provided with a key-ring hole, and the key that key factory produces, the shape of its Handheld Division is identical substantially.Because the characteristic of lock is corresponding one by one, so people generally have with oneself for many keys opening multiple lock usefulness.So many keys are put together, maximum problem is not easy to identify, have plenty of under dim light and do not see Chu, having plenty of the key of can not distinguishing in a big string key with the lock check mark comes, this brings very big trouble just for " opening different locks with different keys ", both lost time and spirit, also may influence the carrying out of thing.In addition, concerning the blind person, in bunch of keys, find out and come just more difficult with the key of locking check mark.

The purpose of this utility model provides a kind of key easy to identify, makes to identify and the key of locking check mark in a glance in big string key.

Realize the utility model of above-mentioned purpose, include a key Handheld Division and a bolt tooth open portion, characteristics of the present utility model are, are provided with at least one convex body for identification usefulness in appropriate position, key Handheld Division, and can be nested with an identification cover that is shaped on word, symbol on this convex body.Promptly on being the key Handheld Division of plane body except that being provided with a key-ring hole, also be provided with one group of convex body, and have the identification cover of numeral or letter, symbol to be nested with on this convex body printing (or write, carve) it on for identification usefulness.Investigation according to observations, common people mostly carry ten with interior key, and what have also carries ten above keys, so the utility model is provided with a convex body at least on the key Handheld Division, two, three convex bodys of operated by rotary motion get final product.Be nested with the identification cover on convex body, can print (or write, carve) on it has numeral or letter, symbol, also can scribble shades of colour.For key and tapered end are checked the number, can on lock body, be provided with and the identical mark of mark on the key.

For convenient various occasions are used, the convex body that the utility model is arranged on the key Handheld Division can adopt various ways, as, convex body is a kind of post tooth that is arranged on the outer peripheral edges of Handheld Division, its can be a kind of on outer peripheral edges the outwards outstanding post tooth that forms, also can be on outer peripheral edges, inwardly to have teeth groove and the post tooth that forms.And, come off from convex body for preventing the identification cover, can be designed to convex body to be the little wedge shape of the big root in top from convex body top to root.

Convex body in the utility model on the key Handheld Division also can have other form of structure, as, on the key Handheld Division, be provided with at least two small through hole that are set in distance, in this small through hole, be inlaid with the paxilla that protrudes for the part of identification usefulness.So the utility model of structure is more suitable for using in the blind person, touches the paxilla that this protrudes from the plane with hand one, can promptly distinguish correct key.

Therefore because the utility model key Handheld Division is provided with the convex body for identification usefulness, then the user can distinguish the key that matches with a certain lockset rapidly easily in bunch of keys, reach save time, laborsaving, the purpose that can get wrong not.

Description of drawings:

Fig. 1 is a forward structure schematic diagram of the present utility model.

Fig. 2, Fig. 3 and Fig. 4 are embodiment schematic diagram of the present utility model.

Embodiment of the present utility model as shown in drawings.

See that by Fig. 1 the utility model includes a key Handheld Division 1 and a bolt tooth open portion 11, two convex bodys 4 that forming inwardly having three grooves 3 on the outer peripheral edges on the key Handheld Division 1, and can on this convex body 4, be nested with an identification cover 5 that is shaped on word, symbol.In the present embodiment, convex body 4 is designed to be the little wedge shape of the big root in top (or claiming inversed taper platform shape) from convex body 4 tops to root.

Fig. 2, Fig. 3 and Fig. 4 are embodiment of the present utility model.Embodiment illustrated in fig. 2 is that a kind of being located at of its convex body outwards given prominence to the post tooth 6 that forms on the outer peripheral edges; Embodiment illustrated in fig. 3 be a kind of and the convex body of analog structure embodiment illustrated in fig. 1-be tooth post 7, the difference that has slightly be three teeth groove 8 and two tooth posts 7 linearly shape arrange and be provided with.Also all be with identification cover 5 (not the drawing among the figure) that are shaped on word, symbol on the tooth post 6,7 among this two embodiment.
