Abstract

The utility model relates to an easy assembling and disassembling clamp, comprising a rotation axis 1, a tension spring 2, a rotation claw A3 and a rotation claw B4. The rotation claw A3 and the rotation claw B4 which are hinged together are respectively provided with at least two hinging seats 31, 41. The same sides of the hinging seats 31 are respectively and fixedly connected with a minor axis which is the rotation axis 1. The same sides of the hinging seats 41 are respectively provided with an inwards concave inner hole which the minor axis can be correspondingly sheathed in at the same time. The utility model has the advantages of simple structure, conveniently assembling, conveniently disassembling, etc.

Description

Clip easy to assemble

The utility model relates to a kind of clip with rotary pawl and elastic component generation clamping action, particularly a kind of clip easy to assemble.

Clip is generally formed with the tension spring of the corresponding contact of two rotary pawls respectively by hinged rotary pawl and two supported ends of rotating shaft by two, generally, behind the shaft set tension spring again the row with two rotary pawls on the pin-and-hole cross-under, because rotating shaft is a separate member, so also need countershaft to implement axially locating at last.As seen, this clip structure complexity is installed inconvenience, demolition is difficulty more, have the clip of the rotary pawl that preferable exterior trim effect can more permanent use for those, owing to need to change easily damaged parts such as tension spring, the clip of this structure especially can not meet the demands.

The purpose of this utility model is to overcome deficiency of the prior art, and provides a kind of simple in structure, adorns, tears open clip easy to assemble easily.

The purpose of this utility model realizes by following approach.

Clip easy to assemble, comprise rotating shaft, tension spring, and hinged rotary pawl A and rotary pawl B, its structure outline be on the rotary pawl A at least two hinged seats spaced apart respectively homonymy be connected with a kind of minor axis, said minor axis is rotating shaft, and a kind of described minor axis of indent can the corresponding simultaneously endoporus that is inserted in respectively at least two hinged seat the same sides spaced apart on the rotary pawl B.

The purpose of this utility model can also reach by following approach.

Said endoporus or be a kind of through hole, or be a kind of blind hole.

Have two hooked scarfs spaced apart on the rotary pawl B, have on the hooked scarf opening down, in order to the clasp joint and the reverse hook groove of supporting tension spring one lever arm, another lever arm of tension spring is then pressed the back of touching at rotary pawl A.

The hook groove preferably is distributed in the outside of rotary pawl B hinged seat.

Preferably also have on the rotary pawl A a kind of can with the projection of tension spring clamping with location rotary pawl A and rotary pawl B relative axial position, projection one side is a right angle step, opposite side then is a slope shape.

Preferably a kind of profile of tension spring is the torsion spring of " bow " shape.

In sum, a rotating shaft and a rotary pawl are affixed, and no longer exist with separate member, so simple in structure; At least two with minor axis as rotating shaft and the corresponding affixed and fixing position of adjacent two hinged seats be the same sides of two hinged seats, make minor axis correspondingly simultaneously to be inserted in the endoporus of adjacent two hinged seats of another rotary pawl, like this, two rotary pawls relatively misplace, can realize separating of the two, so dismounting is extremely convenient; Profile is the introducing of the torsion spring of " bow " shape, not only strengthened torsion from structure, and torsion spring is more convenient for location and installation on rotary pawl, importantly the flexible clamping of a torsion spring and an aforementioned rotary pawl upper protruding block makes tension spring also can be used as the locating piece of location two rotary pawl relative axial positions.This shows that the utility model is real to be a kind of simple in structure, adorns, tears open clip easily.

Accompanying drawing 1 is the structural representation plan view of the utility model most preferred embodiment

Accompanying drawing 2 is left views of Fig. 1

Accompanying drawing 3 is the A-A sectional views among Fig. 1.

Accompanying drawing 4 is the B-B sectional views among Fig. 2.

Below we carry out more detailed description to the utility model in conjunction with the accompanying drawings.

Most preferred embodiment:

With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, clip easy to assemble, form by tension spring 2, rotating shaft 1 and hinged rotary pawl A3 and rotary pawl B4 etc., have two hinged

seats

31,41 on rotary pawl A3 and the rotary pawl B4 respectively, two hinged seats, 31 the same sides are connected with a minor axis respectively, said minor axis be rotating shaft 1, two hinged seat 41 the same sides then respectively indent have a kind of described minor axis can the simultaneously corresponding endoporus that is inserted in, said endoporus is a kind of blind hole.Also have two hooked scarfs 42 that are distributed in hinged seat 41 outsides on the rotary pawl B4, have on the hooked scarf 42 opening down, in order to the clasp joint and the reverse hook groove of supporting tension spring 2 one lever arms, tension spring 2 another lever arms are then pressed the back of touching at rotary pawl A3, and tension spring 2 is torsion springs that a kind of profile is " bow " shape.Rotary pawl B4 middle part also has a kind of platform 43 in order to advance expenditure tension spring 2, like this, can guarantee assembling process, and not with rotary pawl B4 when hinged, tension spring 2 in the raw can not break away from from the hook groove with a lever arm of hook groove clasp joint rotary pawl A3 as yet.Then have on the rotary pawl A3 a kind of can with the projection 32 of tension spring 2 clampings with location rotary pawl A3 and rotary pawl B4 relative axial position, projection 32 1 sides are the right angle step of spacing usefulness, opposite side then for ease of with the slope shape of tension spring 2 flexible clampings.

It is same as the prior art that present embodiment is not stated part.
