Embodiment 1

[0029] refer to figure 1 and figure 2 As shown, the present invention provides a special socket base for crimping. The socket base 1 is hollow cylindrical, and its inner diameter matches the outer diameter of the vertical rod 2 . The socket base 1 is provided with a tapered protrusion 3 in the circumferential direction, and the shape of the tapered protrusion 3 is narrow at the top and wide at the bottom, narrow at the inside and wide at the outside. The socket base 1 is socketed with the pole 2. The socket base 1 is provided with a crimping part, and the socket base 1 is connected to the vertical rod 2 by crimping the crimping part. Wherein, the crimping part 2 is a crimping ring 4 arranged on the top and bottom of the socket base 1 , and the crimping ring 4 is coaxial with the socket base 1 and has the same inner diameter. When in use, the crimping ring 4 is crimped with the vertical pole 2, and the socket base 1 can be closely connected with the vertical pole 2. As a b...

Embodiment 2

[0032] refer to image 3 As shown, on the basis of the first embodiment, as a better embodiment, the crimping ring 4 is evenly provided with openings 5 ​​in the circumferential direction. Setting the opening 5 in the circumferential direction of the crimping ring 4 is beneficial to make the crimping ring 4 and the vertical rod 2 fit together more conveniently, and enhance the stability of the crimping.

Embodiment 3

[0034] refer to Figure 4 As shown, as a better embodiment, the crimping parts are crimping grooves 6 uniformly arranged in the circumferential direction of the socket base 1 . When in use, the socket base 1 and the vertical rod 2 are crimped. Since the crimping groove 6 has reserved a crimping gap, it can effectively promote the fitting of the socket base 1 and the vertical rod 2, and the socket base 1 It can be closely connected with the pole 2.

Abstract

The invention provides a socket-type keyway type steel pipe support, which includes a special socket base for crimping, the socket base is hollow cylindrical, and its inner diameter matches the outer diameter of a vertical rod The circumference of the seat is provided with a conical convex head, the shape of the conical convex head is narrow at the top and wide at the bottom, narrow at the inside and wide at the outside. components, and the socket base is crimped and connected with the vertical rod through crimping components. In the present invention, the processing difficulty is greatly reduced and the processing efficiency is significantly improved by crimping the crimping parts and the vertical rods. The invention does not need welding equipment, electric welding wire and welding gas, and the production process can save more than 70% of electricity and greatly reduce carbon emissions. The invention has sufficient strength, rigidity and stability to ensure smooth and safe construction. The invention has the advantages of simple structure, convenient processing, stable performance, safety and reliability.

Description

technical field [0001] The invention relates to the field of steel pipe scaffolding, in particular to a special socket base for crimping. Background technique [0002] In the prior art, welding is mostly used in the processing methods of scaffolding and its fasteners. The specific steps include: 1. Align the steel pipes to be welded to keep the inner walls flush. Greater than 1mm. 2. For steel pipes and fasteners with different wall thicknesses, organic solvents should be used to remove oil stains before welding, and mechanical or chemical methods should be used to remove oxide films to expose metallic luster. 3. Generally, the welding joint adopts the plug-in form, and the plug-in length is 6-8 times the thickness of the pipe wall. 4. The welded pipe fittings must be cleaned within 8 hours to remove the residual flux and slag. Use boiled 10%-15% alum aqueous solution to paint the joints, and then rinse and dry with water. This method has high technical requirements for t...
