Abstract

The utility model relates to a foldable key holder which comprises an upper cover and a bottom cover of a key lever, a key plate and an elastic trip for positioning the key plate, wherein both sides of the key plate respectively outwards and convexly extend rotating shafts, and one positioning sliding block is formed between each rotating shaft and each key plate. The positioning sliding block is moved in the limited space of the elastic trip, so that the key plate can be folded and contained between the upper and the bottom covers of the key lever in the vertical opposite direction of 180 DEG. The utility model has the advantages of simple structure, flexible and convenient use, portability for a user and high safety. The key plate is not easy to grind or extend outwards to prick clothes.

Description

Collapsible key apparatus

The utility model is a kind of collapsible key apparatus, belongs to daily necessities.

General key 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 a spoon sheet is a metal material, so the spoon sheet when not using, tends to cause because can't collect abrasion or causes damaging 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 puncture clothing.

In order to overcome above-mentioned deficiency, the purpose of this utility model is: design a kind of collapsible key apparatus, it not only can be with on the partly folding the shank of the key that is accommodated in plastic cement system of the metal of spoon sheet, in the bottom, provides convenience and does not have the collection mode of danger; And can go up by the shank of the key large-scale, the spatial accommodation of bottom, 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 key sounding, function such as luminous, allow an ordinary key have more practical value.

A kind of collapsible key apparatus of the utility model, main system includes: cover on the shank of the key, its central authorities have a microscler hollow out to insert for backfolding spoon sheet; The bottom of one the shank of the key, its with the corresponding position of shell fragment, indent has shallow slot ammunition feed sheet location, and is provided with an arc groove for spoon sheet location digging corresponding to the both sides of spoon sheet; Spoonful, its be its do not have spoon line another termination both sides each outwards protruded out a rotating shaft, and respectively be provided with a location slide block between the sheet again in rotating shaft and spoon; One shell fragment, it is that appropriate location at two arms is respectively equipped with an Elastic Sliding zone, is to insert activity for aforementioned positioning sliding block; By with upper member, sheet is sheathed is combined as a whole with shell fragment and spoon earlier, this combination is placed on the bottom of the shank of the key again, and at last with loam cake, the mat screw combines; But the spoon sheet is the marriage relation between its rotating shaft of mat and positioning sliding block and the shell fragment just, and is folding and be accommodated in the hollow out of the shank of the key loam cake.

Wherein, the gauge of this positioning sliding block is bigger than the size of its height.

The utility model has the advantages that: simple in structure, overall appearance, easy to use, can utilize its rich spatial accommodation, increase 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:

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

Fig. 2. be the key combination schematic appearance of the utility model.

Fig. 3. be the utility model key side-looking sectional schematic diagram.

Fig. 4. be the view during the utility model key folds.

Fig. 5. the key that is the utility model is finished folding view.

Fig. 6. be to show the spoon sheet positioning sliding block of Fig. 3 and the marriage relation enlarged drawing between the shell fragment.

Fig. 7. be to show the spoon sheet positioning sliding block of Fig. 4 and the action relationships enlarged drawing between the shell fragment.

Fig. 8. be to show the spoon sheet positioning sliding block of Fig. 5 and the action relationships enlarged drawing between the shell fragment.

Number in the figure is as follows:

1. 3. spoons of sheets of loam cake 2. bottoms

4. shell fragment 5. screws 11. microscler hollow outs

21. shallow slot 22. arc grooves 31. rotating shafts

32. 34. spoons of sheet terminations of 33. spoons of lines of positioning sliding block

41. Elastic Sliding zone

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

At first see also shown in Figure 1ly, the utility model mainly is by a loam cake 1, bottom 2, and the shell fragment 4 of spoonful 3 and a location spoon sheet 3 is formed.Wherein, loam cake 1 central authorities at the shank of the key have a microscler hollow out 11 to insert for backfolding spoon sheet 3; In addition in the corresponding position of its bottom 2 with shell fragment 4, then indent has a shallow slot 21 ammunition feed sheets 4 location, and is provided with an arc groove 22 for spoon sheet 3 location digging corresponding to the both sides of spoon sheet 3.

As for 3 of spoon sheets be its do not have spoon line 33 another termination 34 both sides each outwards protruded out a rotating shaft 31, and be provided with a location slide block 32 between the sheet 3 again in rotating shaft 31 and spoon.

As for 4 on shell fragment is that appropriate location at its two arm is respectively equipped with an Elastic Sliding zone 41, is to insert activity for aforementioned positioning sliding block 32.

By above element, at first, again this combination is placed on the bottom 2 of the shank of the key shell fragment 4 and spoon sheet 3 sheathed being combined as a whole, combine with loam cake 1, mat screw 5 at last.As shown in Figure 2, but the just marriage relation between its rotating shaft 31 of mat and positioning sliding block 32 and the shell fragment 4 of spoon sheet 3 folds and is accommodated in the hollow out 11 of the shank of the key loam cake 1.

Marriage relation as between aforementioned positioning sliding block 32 and the shell fragment 4 then sees also Fig. 3, Fig. 4, shown in Figure 5.As shown in Figure 3, be the state that spoon sheet 3 does not fold, promptly the positioning sliding block 32 of the both sides on the spoon sheet 3 does not produce any action (please cooperating shown in Figure 6 simultaneously) in the elasticity zone of action 41 of shell fragment 4, and is subjected to the restriction of elasticity zone of action 41 and can rotate.When user's desire is accepted spoon sheet 3, as long as gently spoon sheet 3 is derived upward, just interlock positioning sliding block 32 rotates it in elasticity zone of action 41, because the gauge of this positioning sliding block 32 is highly bigger than it, so when rotating, just can be as shown in Figure 7 with shell fragment upwards and strut downwards, spoon sheet 3 slips into back (as shown in Figure 5) in the hollow out 11 of the shank of the key loam cake 1 by the time, this positioning sliding block 32 just is returned to original state (as shown in Figure 8), and can not rotate again.

In sum, a kind of collapsible key apparatus of the utility model can make spoon sheet 3 location and reach the effect that folds by the positioning sliding block 32 of spoon sheet 3 and the marriage relation between the shell fragment 4.And when the taking-up of spoon sheet 3 desires is used,, can easily spoon sheet 3 be ejected with the opposite direction that folds as long as gently press spoon sheet 3 to have another termination 34 of spoon line 33, very convenient.In addition, because the going up of the shank of the key, bottom for cooperating folding of spoon sheet 3, must be strengthened its spatial accommodation; So just can design in the place that does not use with user's needs some 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 the practical value of this key.
