Abstract

The utility model relates to a clip body structure with light clamping force. A metal sheet is mainly made into a body through integral forming. A clamping part which has the functions of opening, closing, and holding is arranged on one end of the body. The other end of the body is formed opposite pressing parts through bending. A backfolding elastic part is arranged between the opposite pressing parts to lead the opposite pressing parts to be mutually connected. The utility model has the advantages of simple structure and easy manufacture. The elastic part and the clip body can have corresponding width and thickness, which leads service life of the elastic part to be improved. In addition, the elastic part can not easily deform or relax, with good usability.

Description

The clamp structure of light clamp

The utility model relates to a kind of clamp structure of light clamp.

The chance of using clip in the general daily life is quite a lot of, and according to clamping strength that clip provided and opinion, can distinguish the clip two big classes of attach most importance to folder power and light clamp, wherein heavily press from both sides power person, as clothes airing clamp, long-tail folder, file folder or the like, and the light clamp person, as tie pin, hair clip or the like; Not outer the system respectively by the both sides of two intermediate plates of its structure is provided with relative pivot ear, and in two intermediate plates, returning spring is set, and mat one pivot is arranged among relative the pivot ear and returning spring, makes this two intermediate plates folding relatively so that clamping action to be provided, and uses for the user.

The above commonly use clamp structure, though it has clamping action, but owing to be that two intermediate plate one returning springs of mat and a pivot combine, make again on the intermediate plate in addition and be provided with the pivot ear, simplify inadequately so seem on the structure, and be loaded down with trivial details inconvenience also in the assembling, be to commonly use clamp structure difficult meaning on making with this to close, and necessity of improvement is arranged in economic benefit.

Secondly, clamp at light clamp, the returning spring torsion that is set must be less, make that so relatively the line of material footpath of returning spring must be thinner, and thinner wire rod is after repeatedly using, just easy deformation and loose, this moment, returning spring just can't provide suitable clamping action power again, clip also loses effect certainly and is dropped, therefore at the clip of light clamp, structure and good design as this obviously bring inconvenience and the inapplicable facts in use easily, and historical facts or anecdotes has necessity of the clamp structure of being redesigned.

The main purpose of the utility model ties up to the clamp structure that a kind of light clamp is provided, it is one-body molded by tinsel, one end forms the folder portion with folding clamping action, the other end forms the relative portion that presses, and the relative spring section that inflection is arranged between portion of pressing is connected, and not only simplifies because of structure in view of the above to make manufacturing easier, simultaneously can be with suitable width of tool and thickness because of spring section and clamp, so its elasticity life-span is more yielding loose, usability and applicability are good, meet functional need.

The utility model is to realize like this, it is mainly by the one-body molded body of making of tinsel, this body one end is made the folder portion with folding effect, the other end bends the portion that presses that forms relatively and can supply to push, and in the relative flexible portion of inflection between portion that presses, the horizontal position of two ends is connected the relative portion that presses.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the External view of the utility model.

Fig. 2 is the structural representation of the utility model.

Fig. 3 is the action schematic representation of the utility model.

The figure number explanation:

(20) clamp (21) folder portion

(211) intermediate plate (212) intermediate plate

(213) double wedge (22) is pressed portion

(23) spring section (231) corner

See also shown in Fig. 1,2, the utility model is mainly by the one-body molded body (20) of making of tinsel, these body (20) one ends are made the folder portion (21) with folding effect, the other end bends the portion that presses (22) that forms relatively and can supply to push, and flexible of inflection (23) between the relative portion that presses (22), and this spring section (23) is connected in the relative portion that presses (22).

Further, this folder portion (21) comprises relative two intermediate plates (211), (212), and wherein can be provided with double wedge (213) on an intermediate plate (211) side, and when not stressing, does not open this two intermediate plate (211), (212) closing each other in body (20).

This presses portion (22) is that tinsel bends the corresponding formation in 180 degree backs, and this spring section (23) folds into  shape, the bending part of the portion that presses (22) that the proper linking in horizontal position of its two end is relative,  shape corner (231) part then reliably withstands on the portion of pressing (22) below, constitute good fulcrum by corner (231) in view of the above, and cooperate the horizontal position of taking out to form favorable elasticity swing effect.

See also shown in Figure 3, when the utility model used, use was the portion of pressing (22) of pushing, and spring section this moment (23) position forms fulcrum at the corner (231) of the portion of pressing (22) below, make intermediate plate (211), (212) be able to open, be folded in the precalculated position for the user with leverage; Waiting discharges the active force of pressing in the portion (22), along with the return action power of spring section (23), makes intermediate plate (211), (212) closing once again to form the clamping positioning action.

The utility model design reason tinsel is one-body molded to go out folder portion (21), press portion (22) and spring section (23), need not see through group and establish the mode moulding, simplifies so structurally obviously commonly use structure, also comparatively easy in the manufacturing, can meet industrial utilization; In addition, because spring section (23) quite (is pressed with tinsel width, the thickness of body (20), can change the width of spring section in addition with actual chucking power size, to close needing of practicality), the horizontal position that adds its  shape structure is connected the portion (22) that presses, just constitute the swing arm effect, therefore not only can provide the light clamp effect, the elastoresistance deformation ability is also higher simultaneously, in other words, though the utility model provides light clamp, unlikelyly cause spring section (23) distortion loose and lose should be powerful easily, be so that use, need that can realisticly use more.

In sum, one-body molded each position of clamp of making of the utility model mat provides the use effect that is difficult for losing chucking power simultaneously.

Claims
