Elastic non-metal snap rings for fence assembly

Abstract

The invention discloses an elastic non-metal clamping ring used for fence assembling. The elastic non-metal clamping ring comprises a body, a vertical bar inserting hole is formed in the middle of the body, an outward flange is arranged at the upper end of the outer circle of the body, an inclined surface which inclines inwards is arranged at the position, located below the flange, of the outer circle, a straight flange is arranged below the inclined surface, the outer diameter of the straight flange is smaller than the outer diameter of the flange at the upper end and a clamping groove is formed between the upper end face of the inclined surface and the lower end face of the flange. A lug which protrudes inwards is arranged on the inner circle face corresponding to the inclined surface of the outer circle and the lug stretches out from top to bottom in an arc-shaped mode. The elastic non-metal clamping ring is used for assembling vertical bars of an assembling-type fence and transverse bars of the assembling-type fence, in the transportation process, the problem that clamping pieces are damaged due to the fact that the clamping pieces are installed in the vertical bars cannot occur, the problem that accessories such as the other vertical bars are scratched cannot occur neither, the trouble that rubber rings are additionally used for being placed at the positions, where the vertical bars are inserted, of the peripheries of the transverse bars so as to perform waterproof sealing and prevent damage, caused by collision between the transverse bars and the vertical bars, to surface coatings is avoided and the cost of the non-metal clamping ring is low.

Description

technical field [0001] The invention relates to a clip ring for fence assembly. Background technique [0002] The prefabricated fence in the prior art, the horizontal fence and the vertical fence are formed by clamping elastic metal clips. The inventor of the present application invented it and published it on April 28, 2004. The publication number is CN2613556Y, and the name is The Chinese patent of "Spring Clip-on Steel Pipe Fence" discloses a spring clip-on steel pipe fence. The metal clips need to be installed in the vertical rail first, and the convex parts on both sides of the clip extend out of the vertical rails on both sides. Then go to the installation site to install the vertical rails and horizontal rails. After arriving at the installation site, the vertical rails equipped with elastic clips are inserted into the matching holes of the horizontal rails, and the convex parts on both sides of the spring clips are in the horizontal rail holes. It pops up automatica...

AI Technical Summary

Problems solved by technology

[0003] The metal clips of this prefabricated fence need to be installed in the vertical rail first, and then the vertical rails and horizontal rails are installed at the installation site. The vertical rails equipped with spring clips are easily damaged during transportation. , It is also easy to scratch other accessories such as vertical bars. It is also necessary to use rubber rings to be placed around the vertical bars of the horizontal bars to perform waterproof sealing and prevent the collision between the horizontal bars and the vertical bars from damaging the surface coating, and the metal card The connection cost itself is also high
