Detailed Description

Referring to fig. 1-6, the folding key of the present invention includes a clamp 1, a key 2 and a clamping mechanism 3 that can make the key 2 be collected in the clamp 1 or expanded outside the clamp 1, the clamp 1 is composed of a first clamping plate 11 and a second clamping plate 12, the clamp 1 includes a holding portion 13 and a clamping portion 14, the clamping mechanism includes a first rivet 31 and a spring plate 32 disposed at the clamping portion 14, the first rivet 31 penetrates through the first clamping plate 11, the spring plate 32, the key 2 and the second clamping plate 12, and the spring plate 32 and the key 2 are clamped between the first clamping plate 11 and the second clamping plate 12. Due to the structure, even if the product is used for a long time due to the existence of the elastic sheet 32, the clamping effect cannot be influenced due to the compensation property of the elastic sheet, and the key cannot be loosened from the clamp. Referring to fig. 7-12, the shape of the spring plate 32 is preferably circular and the cross-sectional shape of the spring plate is preferably arcuate or wavy, such shapes ensuring the resiliency of the grip and the smooth and symmetrical rotation of the key. Other shapes of spring plate may be selected to achieve the same effect. The elastic sheet can be arranged on one side of the key or on two sides of the key, and the elastic sheets are arranged on the two sides, so that the clamping elasticity and the balance can be improved.

In order to further improve the positioning of the key in the desired position during storage and deployment, the first clamping plate 11 and/or the second clamping plate 12 is provided with a positioning projection 15 on the inside around the first rivet 31, and correspondingly, the key 2 is provided with a positioning recess 21 cooperating with the projection. Preferably, as shown in fig. 4, the two

positioning protrusions

15A and 15B are symmetrically disposed around the first rivet 31, and the key 2 can be positioned when being stored in the clamp 1 or being unfolded out of the clamp 1 by 180 °, that is, the two

positioning protrusions

15A and 15B are symmetrically disposed on two sides of the first rivet 31, and a connecting line of center points of the two

positioning protrusions

15A and 15B is consistent with a length direction of the clamp. When the key is unfolded to form an angle of 180 degrees with the length direction of the clamp, the positioning protrusion 15A falls into the positioning pit 21A, and the positioning protrusion 15B falls into the positioning pit 21B; when the key is completely stowed in the space 100 of the jig, the positioning projection 15A falls into the positioning recess 21B, and the positioning projection 15B falls into the positioning recess 21A. That is, the key can be positioned when being completely stored, and the key is further prevented from being loosened from the clamp; when the key is unfolded to 180 degrees, the key can be positioned, the stability of the key in use is improved, and the hand feeling of collection and unfolding is improved. The positioning protrusion and the positioning pit can be arranged on the inner side of one clamping plate and one side corresponding to the key, and can also be arranged on the inner sides of the two clamping plates and two sides of the key. When the inner sides of the two clamping plates are provided with the positioning protrusions, the sizes of the elastic sheets should meet the distribution of the positioning protrusions, so that the elastic sheets cannot be influenced by the positioning protrusions.

In order to reduce the production costs, the projections 15 are formed by making indentations 16 on the outside of the first clamping plate 11 and/or the second clamping plate 12, which is quick and aesthetically pleasing to the outside of the clamp.

In order to make the key beautiful when unfolded, the key is ensured to be 180 degrees at the maximum angle when unfolded with the clamp, although the positioning bulge 15 and the positioning pit can position the key when unfolded at 180 degrees, because the dimensions of the positioning bulge 15 and the positioning pit are small, the positioning effect can be lost under the action of large external force, a baffle plate 17 is arranged on one side of the clamping part of the clamp, and the baffle plate 17 can stop the key from continuously rotating when the key rotates to be 180 degrees with the length direction of the clamp.

In order to facilitate the pulling out of the key from the clamp 1, the key 2 is provided with a pulling part 22, and correspondingly, the clamp 1 is provided with a yielding part 18 capable of exposing the pulling part 22.

The pulling part of the utility model is a groove.

In order to fasten the clamp, the grip portion 14 of the clamp 1 is provided with a second rivet 4 for riveting the first clamping plate 11 and the second clamping plate 12.

In order to make the foldable key portable, the holding portion 14 of the clamp 1 is provided with a hanging portion 19, and the hanging portion 19 shown in the present invention is a circular hole, and may be a technical means commonly used in the technical field.

In order to further improve the hand feeling of the key when the key is unfolded, positioned and stored, the cross section of the positioning bulge 15 is arc-shaped, and the cross section of the pit 21 is triangular.

It is only above the preferred embodiment of the present invention, all according to the utility model discloses a patent application scope structure, characteristic and principle do equivalent change or decorate, all be in the utility model discloses a protection within range.
