Detailed Description

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.

Referring to fig. 1-3, fig. 1 is an exploded perspective view of the anti-drop plastic rivet of the present invention, fig. 2 is an installation diagram of the anti-drop plastic rivet of the present invention, and fig. 3 is a perspective view of a pin bush of the anti-drop plastic rivet of the present invention.

The utility model discloses an anticreep plastic rivet, including cotter 1 and pin 2, cotter 1 includes cotter cap 11 and cotter sleeve 12, cotter cap 11 is fixed in cotter sleeve 12 upper end, first recess 111 has been seted up on cotter cap 11, first recess 111 inner wall upper portion is equipped with card portion 112 of establishing, first recess 111 bottom to in the cotter sleeve 12 seted up blind hole 121, cotter sleeve 12 lower part is seted up at least one second recess 122 that runs through its side and lower terminal surface in order to cut apart into a plurality of supporting legss 123 with cotter sleeve 12 lower part, the degree of depth of second recess 122 is greater than the height of blind hole 121 bottom to cotter sleeve 12 bottom; the pin 2 comprises a pin cap 21 and a pin column 22, and the pin cap 21 is fixed at the upper end of the pin column 22; the pin column 22 can be inserted into the blind hole 121 from the first groove 111 and can outwardly support the supporting leg 123, and the engaging portion 112 can engage the pin cap 21 in the first groove 111.

The utility model discloses an anticreep plastic rivet, through setting up first recess 111 with card portion 112 of establishing, during the use, card portion 112 of establishing will the cotter cap 21 card of pin 2 is located in the first recess 111, can prevent pin 2 is followed roll-off on the pin bush 1 leads to anticreep plastic rivet loses the fastening force. The supporting legs 123 at the lower part of the pin bush 1 are propped open outwards by the pin columns 22, so that the pin bush 1 can be firmly fixed at a connecting position to be connected, and the fastening effect is good.

The pin sleeve cap 11 and the pin sleeve 12 are collinear in central axis, and the pin cap 21 and the pin column 22 are collinear in central axis. So set up, can let anticreep plastics rivet is whole more symmetrical, and the fastening effect of panel is better.

The depth of the first groove 111 is greater than the height of the pin cap 21. So set up, can let the pin cap 21 set up completely in first recess 111, after the installation, because there is not the stress point, the pin cap 21 is difficult for following the extraction, cotter 1 with the pin 2 connection is more stable.

The distance from the bottom of the first groove 111 to the bottom of the pin sleeve 12 is less than the height of the pin post 22. The arrangement is such that the bottom of the pin post 22 protrudes from the bottom of the pin sleeve 12 to ensure that the support feet 123 are spread apart by the pin post 22.

The fastening portion 112 is a first protrusion protruding inward and disposed on the upper portion of the inner wall of the first groove 111. So set up, during the installation, card portion 112 of establishing can block establish around the pin cap 21, make the atress of pin cap 21 more even, more difficult roll-off.

Please refer to fig. 4, fig. 4 is a schematic view of a pin bush structure of the anti-drop plastic rivet of the present invention.

The number of the second grooves 122 is 2. The quantity is relatively common, the production and the processing are convenient, and the using effect is good.
