Description

Technical Field

[0001] The utility model relates to the field of fixed structures, and more specifically, to a metal connection fixed structure. Background Art

[0002] Fixed structure cups are widely used to connect objects. Some metal railings basically need to be stably fixed together using fixed structures. The existing fixed structures generally use direct butt pipes and threaded rollers to connect them directly together, which easily leads to the metal railings only being directly connected end to end. For this reason, we propose a metal connection fixing structure. Utility Model Content

[0008] It also includes four groups of docking half rings and multiple threaded rollers. The four groups of docking half rings are connected to the outer walls of the four docking ports of the cross tube through the threaded rollers.

[0009] Furthermore, the side walls of the four docking ports of the cross tube are provided with auxiliary grooves, and the side walls of the cross tube in the auxiliary grooves are all set as iron sheets with a thickness of 1-2 mm, which facilitates the setting of the iron sheets and the auxiliary grooves, thereby facilitating the iron sheets to slightly approach the axis of the cross tube, and further facilitating the iron sheets to adapt to tubular objects with a diameter of 1-3 mm between the docking ports.

[0010] Furthermore, the side walls of the four docking ports of the cross tube are all provided with embedding grooves, and the width of the docking half ring is adapted to the thickness of the embedding groove, so as to facilitate the positioning of the docking half ring and prevent the docking half ring from sliding after being fixed.

[0011] Furthermore, the clamping block is installed on the inner wall of the iron sheet, and the clamping block is symmetrical about the axis of the cross tube, which makes it convenient for the clamping block to connect with the tube-shaped object.

[0012] Furthermore, the docking block is provided with a threaded hole, and the side wall of the threaded roller is provided with a thread adapted to the threaded hole, so that the threaded roller can conveniently connect the docking half rings together through the docking block.
