Specific embodiment

Just the utility model is further described with specific embodiment with reference to the accompanying drawings below, but the implementation of the utility model Mode is not limited to this.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of button knob catapult is buckled, including female thread 1, and female thread 1 includes 11 He of buckle side Catapult 12,12 1 end face of catapult are equipped with a type chamber 13, and a taper pillar is extended to the opening of the type chamber in the middle part of type chamber 13 14, the surface of taper pillar 14 be equipped at intervals with it is multiple for cut buckle side intubation 15, make the buckle side intubation 15 ends formed it is more The convex knife 17 of the cutting of piece sheet body 16.Cutting convex knife 17 can be triangular in shape.

Preferably, the bottom of type chamber 13 has the arcuate structure 18 to radially expanded space.

Preferably, one end of buckle side intubation 15 is inserted into from type chamber 13, and taper pillar 14 penetrates the cavity of buckle side intubation 15, button Face intubation 15 is gradually strutted by the convex knife 17 of the cutting of taper pillar 14, forms multi-disc sheet body 16.

Preferably, when sheet body 16 is by 18 position of arcuate structure, the sheet body 16 along the arcuate structure 18 surface profile Bending, formation are bent in an arc shape shape.

Preferably, the other end of catapult 12 is equipped with accommodating chamber 19, and the side wall of accommodating chamber 19 is equipped with spring installation step 10, The outer surface of catapult 12 is equipped with the cover riveted step 102 for fixing catapult cover 101, the edge bending of catapult cover 101 At U-shaped structure 103, catapult cover 101 enters catapult 12 from the opening direction lid of accommodating chamber 19, and 103 riveted of U-shaped structure is in cover riveting It closes fixed on step 102.

Preferably, the gap clamping between catapult cover 101 and spring installation step 10 is equipped with a ring spring 104.

In fig. 2 it can be seen that the buckle side intubation 15 on buckle side 11 runs through cloth when female thread to be fixed on cloth 3, Buckle side intubation 15 is gradually strutted by the convex knife 17 of the cutting of taper pillar 14 again, forms multi-disc sheet body 16, and sheet body 16 is due to by type The influence of the arcuate structure 18 of chamber, gradually bends, to be fixed in type chamber 13.

As shown in figure 3, further including a pin thread 2, pin thread 2 includes button pearl 21 and aluminium spike 22, is had in the middle part of button pearl 21 Chamber 23, the bottom of button pearl 21 are equipped with the perforation 24 being connected to the cavity 23, and aluminium spike 22 penetrates cavity 23 and outside from perforation 24 The fixing end 25 that outer diameter is greater than 24 apertures of perforation is squeezed out under the action of power.When pin thread 2 is fixed on cloth 3, aluminium spike 22 is first It through cloth 3, then penetrates in cavity 23, the fixing end for being greater than 24 apertures of perforation by squeezing out outer diameter under the action of external force punching press 25, so that pin thread be made to be fixed on cloth 3.

Preferably, the diameter of the upper end diameter of button pearl 21 to bottom is gradually reduced.When pin thread and female thread dock, on pin thread The big one end of button pearl 21 be inserted into from accommodating chamber 19, due to being stuck in accommodating chamber 19 by the effect of ring spring 104, when extracting button When pearl 21, since 21 surface of button pearl is inclined-plane, can smoothly it be taken out under the action of external force is greater than ring spring elastic force Button pearl 21.

The female thread of the utility model, it is only necessary to which three catapult, buckle side and ring spring accessory compositions subtract than traditional female thread Two accessories are lacked, have reduced use and the assembling flow path of part, decrease the expense of part mold developing, be greatly saved The cost of production.The mode of the catapult connection buckle side of this product is jointly complete by taper pillar on catapult and type chamber At one end of buckle side intubation is inserted into from type chamber, and taper pillar penetrates the cavity of buckle side intubation, and buckle side is intubated gradually by taper pillar The convex knife of cutting strut, form multi-disc sheet body, when sheet body passes through arcuate structure position, the sheet body along the arcuate structure surface Profile bending, formation are bent in an arc shape shape.Sheet body formation is bent in an arc shape shape, and can be firmly fixed on type intracavitary.On taper pillar Provided with convex knife is cut, quickly the intracavitary buckle side of insert type can be intubated and separate sheet, improve packaging efficiency.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and structure, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and their equivalents.
