Specific embodiment

Referring to figs. 1 to Fig. 6, the embodiments of the present invention propose a kind of foldable key, including the shank of the key 1, the key Holding tank 10 is provided on the shank of the key 1, the front end of the shank of the key 1 is hinged with the key bar that can be rotated Shou Na into holding tank 10 2, it further include the elastic device that key bar 2 can be clamped when key bar 2 is unfolded.When key leaves unused, key bar 2 can be rotated and be received It is contained in accommodating groove, key bar 2 is unfolded in use, the rear portion of key bar 2 is by the clamping of the inner wall of elastic device and the shank of the key 1, energy Key bar 2 is swung along the width direction of holding tank 10 when enough avoiding unlocking using the utility model, stable structure, not rapid wear Bad, long service life.

The elastic device includes the limiting stand 21 being arranged on key bar 2, and is arranged on key bar 2 and the limit The elastic slice 3 that platform 21 cooperates, when the key bar 2 is unfolded, the elastic slice 3 cooperates with limiting stand 21 to clamp key bar 2.

Referring to Fig. 3 to Fig. 5, the structure of limiting stand 21 can be following several: one, the limiting stand 21 is to be arranged in key The protruding portion of 2 rear end of bar, the thickness of the protruding portion are less than the thickness of key bar 2；Two, the limiting stand 21 is to be arranged in key The groove of 2 rear end upper surface of bar；Three, the 2 rear end upper surface of key bar is provided with convex block 5, and the limiting stand 21 is key bar 2 The upper part between 2 rear end face of convex block 5 and key bar.

The front side of the limiting stand 21 forms confined planes 212 backwards as a further improvement of the utility model, described When the upper surface of elastic slice 3 and limiting stand 21 cooperates, the leading flank of the elastic slice 3 is abutted with the confined planes 212 to limit key Bar 2 rotates.Using above-mentioned structure, key bar 2 can be clamped, key bar 2 is swung when avoiding unlocking, while being avoided that unlocking again During key bar 2 rotate, kill two birds with one stone.

Certainly, above-mentioned elastic device can also use other structure types, such as including being arranged before mounting groove 10 The spring top bead at end, corresponding position is provided with recessed portion corresponding with spring top bead on key bar 2, after key bar 2 is unfolded, bullet It is clamped in spring decorative pearl on top of an official cap top such as recessed portion and by key bar 2.

Referring to Fig. 2 and Fig. 6, it is provided with location hole 22 on the key bar 2, is provided on the elastic slice 3 and the positioning The positioning protrusion 31 that hole 22 cooperates, when the key bar 2 is accommodated in holding tank 10, the positioning protrusion 31 is caught in the positioning In hole 22.Key bar 2 can be fixed in holding tank 10 by above-mentioned design, avoid key bar 2 deviate from from holding tank 10 and It is worn or damaged other utensils such as electronic product.In addition, since positioning protrusion 31 is arranged on elastic slice 3, store key When key lever 2, positioning protrusion 31 can generate apparent location hand feeling when being caught in the location hole 22, can remind user's key Bar 2 has been stored in place.

In the present embodiment, the shank of the key 1 includes the first lateral plate 11 and the second lateral plate 12, first lateral plate 11 and second Lateral plate 12 is oppositely arranged and surrounds the holding tank 10, and the rear end of the elastic slice 3 and first lateral plate 11 are fixed, elastic slice 3 Front end turns forward distribution along holding tank 10.By 3 clamping of elastic slice when being unfolded to use due to key bar 2, need to store key bar 2 When, it first has to lift on elastic slice 3, is then just able to rotate storage key bar 2 and therefore lifts elastic slice 3, institute for the ease of user State the first recess 121 being provided on the second lateral plate 12 with 3 face of elastic slice.In above-mentioned design, elastic slice 3 is exposed to first In recess 121, elastic slice 3 is lifted to store key bar 2 conducive to user.

Referring to Fig.1 with Fig. 2, the side face with key bar 2 is provided on first lateral plate 11 and/or the second lateral plate 12 The second recess 122.After key bar 2 is accommodated in holding tank 10, wrapped up completely by the shank of the key 1, in this case key bar 2 Produce inconvenient, by opening up the second recess 122 in the shank of the key 1, the side of key bar 2 is made to be exposed to the second recess 122, Thus key bar 2 is produced convenient for user, sharp parts is there will not be and exposes the shank of the key 1.For the ease of carrying, the key The rear end of handle 1 is provided with can be for through-hole 13 that key chain passes through.

The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means The technical solution of purpose belongs within the protection scope of the utility model.
