One intermediate plate, it mainly is to be provided with deep trouth ammunition feed spring element location at end face to position, stage casing, and in the circular hole position corresponding to loam cake, bottom, divides to have protruded out a mast to both sides, can sheathed key piece, packing ring and button;

Two key pieces, it is formed with single order portion respectively endways; And

One spring element is JiongZi Xing, and respectively forms spiral helicine spring in the both sides of Jiong word, on the also sheathed mast of this spring, and between key piece and intermediate plate two sides; In addition, the then sticking respectively side of being located at two key pieces of the both sides least significant end of this JiongZi Xing spring element;

Wherein, intermediate plate is between loam cake and bottom, and loam cake and bottom system opposition and putting, and by the start of spring element and button, key piece is finished required exposed and fold state.

The utility model has the advantages that: simple in structure, overall appearance, practical and convenient.What it not only can finish key piece like a cork takes in and takes out action, and can hold a plurality of different key pieces.Can also utilize simultaneously the spatial accommodation in the shank of the key, 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.

Now in conjunction with the embodiments and conjunction with figs. details are as follows:

See also shown in Figure 1, a kind of collapsible key apparatus of the utility model, it mainly is loam cake 11, intermediate plate 12, bottom 13 by a large-scale the shank of the key, the spring element 3 of two key pieces 21,22 and a location key piece is formed, intermediate plate 12 is between loam cake 11 and bottom 13, and loam cake 11 and bottom 13 are opposition and putting; Wherein, this loam cake 11 is provided with groove 111,131 with bottom 13 the same sides within it, and all forms an arcuation at end face and open 112,132, in addition, respectively has a circular hole 113,133 can insert for button 31,32 respectively in the appropriate location of front end.As for intermediate plate 12 parts, then be to be provided with a deep trouth 121 ammunition feed spring elements 4 location at its end face to position, stage casing, and, divide to have protruded out a mast 122 to both sides in circular hole 113,133 positions corresponding to loam cake 11, bottom 13, can sheathed key piece 21,22, packing ring 33,34 and button 31,32.As for spring element 4 parts, its outward appearance mainly is JiongZi Xing, and respectively forms spiral helicine spring 41,42 in the both sides of Jiong word, and this spring 41,42 also is on the sheathed mast 122, and between key piece 21,22 and intermediate plate 12 two sides; In addition, 43,44 sticking respectively sides of being located at two key pieces 21,22 of the both sides least significant end of this JiongZi Xing spring element 4 make these key pieces produce kinetic energy by the effect of spring element 4.Above-mentioned composition element just forms key constitutional diagram as shown in Figure 2, and auxiliary by Fig. 3 then more can be known the bonding state of finding out therebetween.

As for the action situation of the utility model, then see also Fig. 4, Fig. 5 and the Ming Liao of getting final product shown in Figure 6.As shown in Figure 4, the original system of key piece 21 holds by spiral spring 41, make in its inner groovy that must be inserted into loam cake 11 111, and its terminal rank portion 211 of mat resists in groove 111 and fixes.When the user desires to take key piece, as long as then press the button 32, make the rank portion 221 of key piece 22 break away from groove 131 between resistance, and glue the spring element 4 generation effects of establishing by the one side, cause these key piece 22 quilts and ejected outside the shank of the key (as shown in Figure 6) and used; Otherwise, if this will be exposed to the outer key piece of the shank of the key folds, then, it arrives the location as long as being bent 180 ° of angles in the other direction with level, the application of force gets final product slightly laterally again, at this moment, because the secondary action again of spiral spring 41,42, the key piece that is just presented as shown in Figure 5 folds state.
