" shape, it is female Button hold close end inner edge have a circular hole, the circular hole be male and female pressing at, Such box and pin is respectively embedded on the various two articles to be engaged, then plus Pressure fastens. The utility model can make two articles snapping closely knit, steady Gu.

Description

Tightening connecting elements

The utility model relates to a kind of fastener, is meant especially a kind ofly two articles is engaged easily and to make closely knit, the firm fastener of two articles snapping.

At present, the combination of general two articles is finished with mechanical components such as iron (steel) nail, rivet or screws, and these connection sets have following shortcoming:

The combined structure of iron (steel) nail utilizes hammer a that iron (steel) nail 1 is knocked on two objects of desiring to combine 2 as shown in Figure 1, makes it reach the purpose of joint.Though this Placement can reach the purpose of combination, it only has the joint effect, and can't change two articles 2 easily, then feels inconvenience as the situation that desire is changed.Moreover it is not enough and cause slippage, loosening to connect the combination force that easily makes two articles 2 with iron (steel) nail 1, and therefore this connection set difficulty meets the high and combination of interchangeability that modern goods is pursued, changes requirement easily.

The combining structure of rivet as shown in Figure 2, after object 3 borings with two desires joints, rivet 4 is placed in the hole 30, become the rivet head 40 of gill fungus shape with pressurization rivet 4 two ends, to reach the purpose that engages two articles, though this kind joint construction has reached the requirement of driving fit, but when desiring to change two articles 3, have only the destruction rivet, have no other way, this kind combination only has conjugation and can't separate, very inconvenience.

The combined structure of screw as shown in Figure 3, its combined structure to rivet 4 is similar, screw 5 is placed in the hole that two articles 6 bored, with nut 7 the other end is locked again, to reach the purpose of joint, though this kind combined structure can reach the requirement of joint, implementing to change needs when separating with tool operation, also is inconvenience.

The purpose of this utility model is to overcome above-mentioned shortcoming, proposes a kind of new fastener.

The fastener that the utility model proposes mainly comprises a pin thread and a box, wherein the pin thread head end is gill fungus shape or other geometrical shapies (as four jiaos of bodies, hexagon), and stretch out one for columned pillar, the fixing rib that four projections and symmetrical umbrella frame frame shape are arranged in the middle of the pillar, the pressing end bump of pillar be "

" shape or other geometrical shapies (as hemisphere face body, four jiaos of bodies, hexagon), it is to hold with box to close end pressing part; The box head end is the ware shape of hollow, in a circular hole is arranged, the aperture just cooperates the size of pin thread pressing end, box holds and closes the edge compressing tablet that end has two symmetries to protrude, compressing tablet can make box become firmly to be combined into one with object whereby, with above-mentioned joint construction, the pressing end of pin thread projection is aimed at box hold and close the pressing of end inner edge circular hole and can fasten and be embedded with male and female two articles, and snapping is closely knit.

Details are as follows to the utility model below in conjunction with preferred embodiment and accompanying drawing, among the figure:

The schematic representation that Fig. 1 closes for existing iron (steel) nail joint;

Fig. 2 is the schematic representation of existing riveted joint;

Fig. 3 is the schematic representation of existing screws;

Fig. 4 is the front elevation of pin thread in the utility model;

Fig. 5 is the worm's eye view of pin thread in the utility model;

Fig. 6 is the plan view of box in the utility model;

Fig. 7 is the front elevation of box in the utility model;

Fig. 8 is the utility model embodiment's a schematic representation.

Shown in Fig. 4-7, the utility model comprises a pin thread 8 and a box 9, and wherein pin thread 8 head ends are gill fungus shape 80, and pillar 81 is cylindric, and the fixing rib 84 of four projections and symmetrical umbrella frame frame shape are arranged in the middle of the pillar 81, pin thread pressing end bump 83 be "

" shape, pressing end bump 83 and box hold and close end 90 fastenings whereby, and the fixing rib 84 of four projection symmetry umbrella frame frame shapes is withstood the interior circular hole edge of object after pin thread 8 embeds on the pillar 81, and overall appearance meets closely knit, the firm requirement of snapping.In addition, box 9 head ends are the ware shape 91 of hollow, in a circular hole 94 is arranged, the aperture just cooperates the size of pin thread pressing end 83, box holds and closes the edge compressing tablet 93 that end 90 has two symmetries to protrude, when box 9 embedded, compressing tablet 93 compressions in edge can make box 9 and object link into an integrated entity after holding and closing the interior circular hole that end 90 passes object.

The situation that the utility model is implemented as shown in Figure 8, respectively bore suitable circular hole on two

plate bodys

10,11 that desire is engaged so that box and

8,9 is pressed into respectively is fixed on 10,11 of the plate bodys, therefore lock on the plate body 10 of pin thread and appear a pressing end 83 that protrudes, be embedded with and only seem box on the plate body 11 of box and hold and close end inner edge 90, if being aimed at box, the pressing end 83 of pin thread holds circular hole 94 pressings of closing end inner edge 90, then box holds the circular hole 94 sapwood material that close end inner edge 90 and promptly is attached on pin thread pressing end 83 and pillar 81 interfaces, makes two plate bodys obtain closely knit joint.

In sum, the utility model can not only be realized effectively combination really, and can save joint, changes man-hour, and can get closely knit snapping.

Claims

1, a kind of fastener, it comprises a pin thread and a box, it is characterized in that described pin thread head end is the gill fungus shape and stretches out a columned pillar, and the fixing rib of four projections and symmetrical umbrella frame frame shape is arranged in the middle of the pillar, the pressing end bump of pillar be " " shape, it is to hold with box to close end pressing part; Described box head end is the ware shape of hollow, in a circular hole is arranged, the aperture just cooperates the size of pin thread pressing end, box holds and closes the edge compressing tablets that end has two symmetries to protrude.
