Technical Field

The invention belongs to the technical field of guardrails, and particularly relates to a self-fastening type assembled guardrail.

Background

The guardrail is a fence, and is mainly used for protecting and protecting personal safety and equipment facilities in occasions such as houses, roads, commercial districts, public places and the like, and generally comprises upright posts and cross rods, wherein the cross rods are welded on the upright posts; 2. welding is not beneficial to environmental protection and the health of workers; 3. welding has certain quality defect, and the welding seam is easy to break after long-time use, and the service life is short.

Disclosure of Invention

The invention provides a self-fastening type assembled guardrail which can solve the problems pointed out in the background technology.

The utility model provides a from fastening formula equipment guardrail, includes hollow stand and horizontal pole, peg graft on the hollow stand of both sides at the both ends of horizontal pole, the both ends of every horizontal pole all are equipped with the through-hole that the vertical direction set up, the through-hole all is located in the cavity of hollow stand, all be equipped with the connecting rod in the cavity of the hollow stand of both sides, the connecting rod is inserted in every through-hole with one side, connects it fixedly.

Preferably, the connecting rod is linearly decreased progressively from top to bottom, and the shape of the through hole is matched with that of the connecting rod.

Preferably, the connecting rod is conical, and the through hole is a conical hole matched with the through hole.

Preferably, the inner sides of the hollow upright posts are correspondingly provided with inserting holes, and two ends of the cross rod are inserted into the inserting holes on two sides.

Has the advantages that: the invention provides a self-fastening type assembled guardrail, the whole assembling process is free from welding, the assembling efficiency is very high, after pre-positioning is completed, quick assembling can be completed by inserting a connecting rod, the production efficiency is high, manual use is reduced, and enterprise benefits are improved; the product is very environment-friendly and healthy, the quality of the product is relatively high, and the service life is long; the connecting rod is the toper and can realize fastening certainly, in the use, can connect more and more tightly.

Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

Example (b):

as shown in fig. 1-5, a self-fastening assembled guardrail comprises hollow columns 1 and cross rods 2, wherein two ends of each cross rod 2 are inserted into the hollow columns 1 at two sides, insertion holes 12 are correspondingly formed in the inner sides of the hollow columns 1, two ends of each cross rod 2 are inserted into the insertion holes 12 at two sides, through holes 3 arranged in the vertical direction are formed in two ends of each cross rod 2, the through holes 3 are located in cavities 11 of the hollow columns 1, connecting rods 4 are arranged in the cavities 11 of the hollow columns 1 at two sides, and the connecting rods 4 are inserted into the through holes 3 at the same side to be connected and fixed; the cross rod 2 is sequentially inserted into the insertion holes 12 of the hollow upright posts 1 at two sides, the position is adjusted, the through holes 3 at the same side are aligned, and the connecting rod 4 is inserted into the through holes for corresponding connection and fixation.

In order to realize from the fastening, improve the fastness of connecting, connecting rod 4 top-down is linear to decrease progressively, and the shape of through-hole 3 is rather than coincide, and connecting rod 4 is the toper in this embodiment, and through-hole 3 is the bell mouth rather than matching.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
