Description

Square tuber pipe and support angle sign indicating number in it

Technical Field

The utility model belongs to the technical field of the tuber pipe processing, a square tuber pipe and support angle sign indicating number in it is related to.

Background

The promotion of the intensity of body is realized through the inside curl to the tip of square tuber pipe, also be used for the connection of tuber pipe range group team, but two inside curls in the perpendicular angle department of square pipe are through cutting out the back infolding, need maintain inside curl and pipe wall vertical and fixed just can play better effect, consequently generally realize through the welded mode, however, to the thinner square pipe of pipe wall, its inside curl is also thinner, intensity is weaker, can not give the effect of playing fine stay tube body shape, joint strength is also lower when each tuber pipe range group team.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that exists to current technique, provide a square tuber pipe and interior support angle sign indicating number thereof, the utility model aims to solve the technical problem how improve the intensity of tuber pipe.

The purpose of the utility model can be realized by the following technical proposal: the square air pipe and the inner supporting corner brace thereof are characterized in that the square air pipe comprises a pipe body, four inner turned edges which are respectively vertical to four straight wall surfaces of the pipe body are arranged at the end part of the pipe body, a limiting turned edge which is parallel to the pipe wall where the inner turned edge is arranged at the inner end of each inner turned edge, and a limiting part which extends towards the outer side of the pipe body is arranged on each limiting turned edge; the inner support angle code comprises two positioning pieces which are vertical to each other, and the inner side of each positioning piece is provided with an inner pressure part which can abut against the inner side surface of the limiting flanging and is vertical to the positioning piece.

Furthermore, the outer side of the positioning sheet is provided with an outer pressing part which can abut against the inner side surface of the pipe wall and is vertical to the positioning sheet.

Furthermore, the middle part of the inner curled edge is provided with a deformation convex rib, and the positioning sheet is provided with a positioning groove matched with the deformation convex rib.

Furthermore, the inner support corner brace further comprises a riveting hole located between the two positioning pieces.

Rivet is worn to establish in riveting hole department, and it is fixed with two interior curls of tuber pipe to support the angle sign indicating number in with, the location of interior splenium and external pressure portion realization and tuber pipe on the spacer, press the portion to insert promptly and establish in the slot that interior curl, spacing turn-ups, spacing three formed, and external pressure portion then supports and leans on the internal face of body.

Through the connection of the inner support angle brace, the strength of the inner curling edge can be enhanced, the verticality of the inner curling edge and the pipe wall can be maintained, and the overall strength and reliability of the air pipe are improved.
