Description

Clip

The utility model relates to a kind of clip, belongs to a kind of fastening piece.

Existing anchor clamps, mostly as shown in Figure 1, form by two intermediate plates that articulate 10 and the pressure handle 100 inboard wind springs 11 and a bearing pin 12 all members that are positioned on two intermediate plates 10, during assembling, must be earlier with two intermediate plates, 10 mutual fits, make the perforation 102 on two intermediate plates, 10 upper ear seats 101 involutory mutually, the writing that surpasses all the others spring 11 then, 102 alignd with perforation in Qi Quan hole 110, then bearing pin 12 is passed perforation 102, circle hole 110 after, loosen wind spring 11, make wind spring two tail ends, withstand two intermediate plates 10 respectively, and then with bearing pin 12 two ends separately punching press fix, anchor clamps are just calculated installation.This anchor clamps, during assembling, perforation 102 is involutory difficult with the circle hole 110 of wind spring 11, especially is difficult for compression and fixing, careless slightly in wind spring 11 assemblings, and wind spring 11 meeting bullets take off and cause danger, so very inconvenient.

The purpose of this utility model is that a kind of improved clip will be provided, and its assembling can improve efficiency of assembling easily, saves man-hour, reduces cost.

The purpose of this utility model is achieved in that this clip is assembled by two intermediate plates, wind spring, latch, two intermediate plates top is the press part, one of them inner face both sides, intermediate plate press part, be provided with paired inside and outside ear seat, one end of inner ear seat is provided with through hole, external ear seat one end inboard is provided with the bottom and has the caulking groove of perforation: in another inboard, intermediate plate press part, be provided with and can insert that two in the middle of the external ear seat articulate ears in two pairs of first intermediate plates, articulate ear and be provided with the abaculus that embeds in the external ear seat caulking groove; Wind spring is positioned between two intermediate plates, and its two ends bar is stuck in the set groove of two intermediate plates, and then with wind spring and two intermediate plate cross-under location, the utility model assembling easily, and is sturdy and durable for latch.

The utility model advantage:

1, by the caulking groove because of the external ear seat of intermediate plate, is connected with the slideway of inclination, makes abaculus on the pivot joint ear of another intermediate plate, be easy to enter in the caulking groove of external ear seat, insert between the inside and outside ear seat so that articulate ear; And the wind spring two ends can snap in the groove set on two intermediate plates, certain location, wind spring is difficult for jumping out when assembling, thus safety during assembling, easily, speed is fast, efficient height, corresponding reducing cost.

2, because of utilizing the ear seat that has caulking groove on intermediate plate of clip, with the pivot joint ear that has abaculus on another intermediate plate, interlock is pegged graft mutually, thus after two assemblings of clip, solid and reliable, do not come off, sturdy and durable.

The utility model concrete structure is provided by following examples and accompanying drawing thereof:

Fig. 1 is existing clip perspective exploded view;

Fig. 2 is the utility model three-dimensional exploded view;

Fig. 3 is the utility model assembling back stereogram;

Fig. 4 is that the utility model ear seat is partly assembled the back sectional view;

Describe in detail below in conjunction with accompanying drawing:

Referring to Fig. 2,3,4, the utility model is assembled by two intermediate plates, wind spring, latch, it is characterized in that:

Two intermediate plates, 2,3 tops are press

part

20,30, on the internal face above two intermediate plates, be respectively equipped with

groove

21,31, inner face both sides in the press part 20 of intermediate plate 2, be provided with the inside and

outside ear seat

22,23 of paired setting, one end of each inner ear seat 22 is provided with through hole 220, at the inner side surface of two external ear seats 23, is provided with oblique slideway 230, with the caulking groove 231 that is connected with slideway 230, caulking groove 231 bottom centre, corresponding with the through hole 220 of inner ear seat 22, be provided with through hole 232; Press part 30 internal faces of intermediate plate 3 are provided with two and articulate ear 32, articulate ear 32 and intermediate plate 2 inside and

outside ear seat

22,23 to constitute the gap corresponding, and the caulking groove 231 of corresponding external ear seat 23, be provided with to outer lug and embed the circular abaculus 320 of caulking groove 231, simultaneously, be provided with and the perforation 232 of external ear seat 23 and the through hole 220 corresponding pivoted holes 321 of inner ear seat 22; Wind spring 4 two ends bars 40 are positioned to be located between the

intermediate plate

2,3 in the

groove

21,31 of

intermediate plate

2,3; Latch 5 passes the through
