Abstract
The utility model provides a self-tightening clamping ring which can overcome the shortcomings in the prior art that the structure is complicated and the self-tightening effect is not ideal. The self-tightening clamping ring is characterized in that the utility model comprises a piece-shaped clipping belt forming the clamping ring body, one end of the clipping belt is a tongue-shaped extension part, the belt body of the other end is provided with an opening, the two ends of the clipping belt are provided with an upper bending section bent in the same direction, the width of the tongue-shaped extension part is smaller than that of the opening on the other end of the clipping belt, the clipping belt is bent in the reverse direction of the upper bending section, the tongue-shaped extension part runs through the opening of the other end of the clipping belt to form the clamping ring structure. The self-tightening clamping ring of the utility model has a simple structure, which can finish a self-tightening and clipping process through the bending of the piece-shaped clipping belt and the self bending force of the clipping belt, the clipping effect is obvious.
Description
Technical field
A kind of clip of the utility model relate generally to relates to a kind of self-tightening clamp structure especially.
Background technique
Self-tightening clamp structure, promptly the clip of being done by spring thread or spring steel band itself is well-known, this clip is also referred to as permanent tension force clip technically.This clip is because its intrinsic elasticity is in the clamped position that it closes under normal state, its simplest form is made of spring thread, and the end of spring thread is overlap joint and protruding mutually, can open clip by subtend ground compressing two bond ends.Unclamp two outwardly directed ends on the flexible pipe once being contained in, clip just is in clamped position, and existing yoke configurations more complicated all.
Publication number is that CN1208129 is a kind of clip, and it comprises: one has first end and cranse part second end, that be made of metal; And the clamp lug with shape, described clamp lug is arranged on the residence that overlaps and states a certain position on the described cranse part of first end when described cranse partly forms an annular shape, described clamp lug can compress on the circumferencial direction of described ring, to reduce the diameter of described ring, it is characterized in that: be formed with a Y shape bifurcated in described cranse part first end, described Y shape bifurcated comprises a pair of Y-piece; And a pair of recess that is formed in described cranse each lateral margin border partly, when described cranse form partly that described ring shape, described first end are overlaped by described cranse part and described recess when interior, described recess can hold the Y-piece of described Y shape bifurcated respectively.There is baroque problem equally in it, and the self-tightening effect is bad.
The model utility content
The purpose of this utility model provides a kind of self-tightening clamp structure, to overcome existing yoke configurations complexity, the shortcoming that the self-tightening effect is bad.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of self-tightening clamp structure, it is characterized in that, comprise that one constitutes the sheet clamping band of clip integral body, described clamping band one end is a tongue extension, the other end belt body is provided with opening, and clamping band two ends are provided with the homotropous turn of bilge of going up, and the width of described tongue extension is less than the width of clamping band the other end opening, the clamping band is towards going up the opposite direction bending of turn of bilge with described, and tongue extension is passed clamping band the other end opening and formed yoke configurations.
In the utility model, described clamping band middle part also is provided with opening, clamping tension when avoiding clip clamping leather hose etc. soft and damage gripped object.
Described clamping band carries out the transition to tongue extension by tapering part and fillet part from its full duration, has guaranteed corresponding mechanical strength.
The last turn of bilge top of described tongue extension and clamping band opening one end is all arc limit structure, stabs the user when avoiding using clip.
Self-tightening clamp structure of the present utility model, simple in structure, by the bending of single sheet clamping band, utilize the bending force of clamping band self can finish the self-tightening clamping, grip is obvious.
Description of drawings
Fig. 1 is the utility model clip clamping band deployed configuration front view.
Fig. 2 is the utility model clip clamping band deployed configuration side view.
Fig. 3 is the structural representation after the moulding of the utility model clip.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, the schematic representation of the utility model clip clamping band 1 deployed configuration, one end of clamping band 1 is a tongue extension 2, clamping band 1 carries out the transition to tongue extension 2 by tapering part 11 and fillet part 12 from its full duration, and the radius of the angle of tapering part 11 and fillet part 12 can mechanical strength as required be provided with.
The other end belt body of clamping band 1 is provided with opening 3, and its width is slightly larger than the width of tongue extension 2, and tongue extension 2 is provided with turn of bilge 21, and clamping band 1 opening one end is provided with turn of bilge 31, and last turn of bilge 21 is identical with the bending direction of last turn of bilge 31; Last turn of bilge 21 tops of tongue extension 2 are arc limit 22, and last turn of bilge 31 tops of clamping band 1 opening one end are arc limit 32, stab the user when avoiding using clip.
The clamping tension and damage gripped object when soft for fear of clip clamping leather hose etc., clamping band 1 middle part also is provided with opening 13, so that soft system gripped object bloats from opening, as being provided with two openings in the present embodiment.
Referring to Fig. 3, only need make clamping band 1 can finish the moulding of clip towards the direction bending opposite with last turn of bilge 21 and last turn of bilge 31, tongue extension 2 is passed the opening 3 of clamping band 1 the other end, and the part of the part of pecker 2 and opening 3 is overlapping, and whole clamping band 1 forms yoke configurations.Turn of bilge 21 and last turn of bilge 31 can unclamp clip on two clenching of the hand, and unclamping the both hands clip is self-tightening clamping gripped object.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
