Abstract

The utility model relates to a telescopic key which is composed of a key holder which is provided with an upper cover and a bottom cover, a key sheet and an elastic sheet which can tow the key sheet to make telescopic movement, wherein, the bottom cover of the key holder is provided with a groove for containing the key sheet, the front surface of the top end of the key sheet extends upwards to form a convex column, and the convex column can pass through the upper cover and can be sheathed with a pushing handle. Because the pulling handle can be exerted with force, the key sheet can generate the action that the key sheet protrudes from the key holder forward or shrinks in the key holder backward; in addition, because one side of the key sheet is towed by the elastic sheet, and the other side of the key sheet attaches to the wall surface of the bottom cover of the key holder, when the key sheet is extended out or shrunk in by the pulling handle, the key sheet can obtain steady locating.

Description

Scalable key

The utility model is scalable key, belongs to daily living article.

At present, the employed key of people mostly is by a shank of the key and spoonful be combined into fixed mode, and usually because the shank of the key is a plastic cement material, and the spoon sheet is a metal material, so the spoon sheet when not using, tends to cause because can't collect wearing and tearing or is directed at damage because of child plays; Moreover the traditional key of this kind also carries quite inconvenience, if there is not key case to deposit for it, no matter then be to be placed on pocket or to be suspended on the waistband, all can feel inconvenience, indecency, even stab out clothing.

In order to overcome above-mentioned deficiency, the purpose of this utility model is: design a kind of scalable key, it not only can partly be accommodated in the metal of key piece on the shank of the key of plastic cement system, in the bottom, and can utilize the shank of the key bigger last, bottom spatial accommodation, arrange and plan the design of many electronic circuits, such as remote control, antitheft, seek car, call out the car owner, call out key or make functions such as key is luminous, sounding, make an ordinary key of script have more practical value.

A kind of scalable key of the utility model includes: cover on the shank of the key, in position open the passage of a microscler sky; The bottom of one the shank of the key, in have a groove; One key piece, its top face up and are extended with a projection, and sidepiece then is embedded with a shell fragment; One shell fragment, the one end is embedded at the sidepiece of key piece, and end then is fixed in the bottom of the shank of the key in addition; After the above-mentioned elements combination, projection penetrates the passage and overcoat one handle of loam cake, and mat forces in handle can make the key piece generation stretch out forward or the action of retraction the shank of the key backward; Simultaneously, the strength of mat shell fragment, a side wall surface that can make key piece be held in the bottom groove produces on-position and locatees.

Wherein, shell fragment stretches out or retraction all is a case of bending during in the fixed point of the shank of the key at key piece.

The utility model has the advantages that: simple in structure, overall appearance and easy to use, not only can finish the action that the shank of the key was taken in or stretched out to key piece like a cork, and because of it has bigger the shank of the key spatial accommodation, can also utilize this spatial accommodation install other such as remote control, antitheft, call out the car owner, call out key, seek car, make electric functions such as key is luminous, sounding, to improve its practical value.

The utility model has following accompanying drawing altogether:

Fig. 1 is the key outward appearance exploded view of the utility model.

Fig. 2 is the combination appearance figure of Fig. 1.

Fig. 3 is the view that the utility model stretches out key piece.

Fig. 4 is the view of the utility model with the key piece withdrawal.

Number in the figure is as follows:

1. the shank of the key 2. key pieces 3. shell fragments

4. handle 11. loam cakes 111. passages

12. bottom 121. grooves 21. projections

Now details are as follows for embodiment and conjunction with figs.:

See also Figure 1 and Figure 2, the utility model is mainly by loam cake 11, bottom 12, one key pieces 2, and a shell fragment 3 is formed; Wherein, but loam cake 11 is locked with bottom 12 mat screws, loam cake 11 is opened the passage 111 of a microscler sky in an appropriate location, then having a groove 121 in the bottom 12 of the shank of the key holds key piece 2 and its slippage is provided, key piece 2 tops face up and are extended with a projection 21, the passage 111 and overcoat one handle 4 of its penetrable loam cake, mat force in handle 4 can make key piece 2 generations stretch out forward or the action of retraction the shank of the key 1 backward.In addition, sidepiece at key piece 2 is embedded with a shell fragment 3, the end in addition of shell fragment 3 is fixed on the bottom 12, this shell fragment 3 stretches out or retraction all is a bending (as shown in Figures 3 and 4) during in the fixed point of the shank of the key 1 at key piece 2, the strength of shell fragment 3 bendings by this, the left side wall that just can make key piece 2 be held in bottom groove 121 produces the state of a braking, reaches key piece and arbitrarily stretches in the shank of the key, and can stably obtain the location.

Claims

1. scalable key, it is characterized in that: this key includes:

Cover on one the shank of the key, open the passage of a microscler sky thereon;

The bottom of one the shank of the key, in have a groove;

One key piece, its top face up and are extended with a projection, and sidepiece then is embedded with a shell fragment;

One shell fragment, the one end is embedded at the sidepiece of key piece, and end then is fixed in the bottom of the shank of the key in addition;

After the above-mentioned elements combination, projection penetrates the passage and overcoat one handle of loam cake, and mat forces in handle can make the key piece generation stretch out forward or the action of retraction the shank of the key backward; Simultaneously, the strength of mat shell fragment, a side wall surface that can make key piece be held in the bottom groove produces on-position and locatees.

2. a kind of scalable key according to claim 1 is characterized in that: wherein, shell fragment stretches out or retraction is a case of bending during in the fixed point of the shank of the key at key piece.
