Description
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, parts such as outside decoration and guardrail often can involve square pipe and pipe connection, these section bars that need to connect generally are metal material such as steel or aluminum alloy, be connected of square pipe and pipe of steel 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 square pipe and pipe of aluminum alloy 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 problems, the utility model provides a need not the welding, the installation is dismantled conveniently, is applicable to the connection structure of the side pipe of multiple metal material and pipe.
The utility model discloses a connection structure of square pipe and pipe, including square pipe, connecting piece and connecting bolt.
The square tube is provided with two circular through holes at the joint.
The connected end face of the square tube is in a concave arc shape.
The round tube is provided with four round through holes at the joint.
The connecting piece is "T" type.
The connecting piece is transversely provided with two circular through holes on the left side and the right side respectively, the two circular through holes are symmetrically distributed, and the two circular through holes are arranged in the vertical direction.
The left side and the right side of the vertical direction of the connecting piece are respectively provided with a fixing piece, and the fixing pieces are perpendicular to the T-shaped plane of the connecting piece.
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 carry out mechanical connection, convenient operation, low cost, facilitate promotion with different metal section bar side pipes and pipe through the connecting piece.
