Abstract

The utility model discloses a reliable connection structure of side pipe and pipe, including square pipe, pipe and connecting bolt, square pipe both sides set up first through-hole and second through-hole respectively, first through-hole is pipe installation nested position mutually, and its radius size is unanimous with pipe radius size, the second through-hole is connecting bolt erection joint position, the pipe is connected erection joint position and is set up the third through-hole, the third through-hole is unanimous with second through-hole radius size. The round pipe penetrates through the first through hole of the square pipe, the third through hole of the round pipe is aligned with the second through hole of the square pipe, the square pipe and the round pipe are connected together through the connecting bolt, and then the square pipe and the round pipe are mechanically connected. The utility model discloses the structure passes through mechanical connection's mode, realizes the square pipe and is connected with the pipe, can improve the intensity of connecting the position, convenient operation, low cost, facilitate promotion.

Description

Reliable connecting structure of square pipe and circular pipe

Technical Field

The utility model relates to a technical field is connected to the tubular product, especially indicates a connection structure of square pipe and pipe.

Background

At present, at some courtyard gates, the stair railing, the outside is decorated, parts such as guardrail often can relate to square pipe and be connected, these section bars that need to connect generally are metal material such as steel or aluminum alloy, be connected of the square pipe of steel and pipe to the section bar, can connect through the welding, but the welding can lead to dismouting and transportation inconvenient, influence the efficiency of dismouting transportation, be connected of the square pipe of aluminum alloy and pipe to the section bar, the welding degree of difficulty is big, welding efficiency is low, only connect through mechanical means.

Therefore, the utility model provides a need not field weld, convenient side's pipe and pipe connection structure are dismantled in the installation.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a need not the welding, the installation is dismantled conveniently, is applicable to the connection structure of square pipe and pipe.

The utility model discloses a reliable connection structure of square pipe and pipe, including square pipe, pipe and connecting bolt.

And a first through hole and a second through hole are respectively arranged on two sides of the square tube.

The first through hole is a mutually embedded position where the circular tube is installed, and the radius of the first through hole is consistent with that of the circular tube.

The second through hole is a connecting bolt mounting and connecting position.

And a third through hole is arranged at the connecting and mounting position of the circular tube, and the radius of the third through hole is consistent with that of the second through hole.

Compared with the prior art, the beneficial effects of the utility model are that:

this kind of connection structure can realize low cost, convenient feasible connection between different metal section bar side pipes and the pipe, can effectively strengthen the bulk joint strength between side pipe and the pipe simultaneously, the utility model discloses the structure utilizes the bolt to realize being connected of different metal section bar side pipes and pipe through mechanical connection mode, convenient operation, low cost, facilitate promotion.
