Cross type fixed-connection clamp

Abstract

The invention belongs to the technical field of pipeline connection, and relates to a cross-type fixed connection buckle. The ends of the first main rod and the second main rod are respectively provided with a first cross-bar buckle and a second cross-bar buckle, which are respectively used to connect from the upper end and the second main rod. The two directions of the lower end are embracing card reception connecting pipes; the front end of the first main rod is the No. No. Ⅲ vertical rod section, the front end of the second main rod is the downwardly curved No. 2 vertical rod segment, and the other end of the No. 2 vertical rod segment is connected with the upwardly curved No. 4 vertical rod segment through the vertical rod convex of the concave arc structure , No. Ⅲ vertical bar section and No. Ⅳ vertical bar section are connected as a whole through the horizontal bar with convex arc-shaped structure; between No. Ⅲ vertical bar section and No. The rod sections are arranged axisymmetrically with each other; the structure design is novel, the principle is scientific, the connection speed is fast, the stability is strong, the disassembly is easy, and the portability is convenient.

Description

Technical field: [0001] The invention belongs to the technical field of pipeline connection, and specifically relates to a cross-type fixed connection buckle, which can be widely used in the two-two connection of various pipelines without using tools such as screws, nuts, flanges, etc., and has the advantages of convenient use, firm connection, etc. features. Background technique: [0002] The methods of connecting two pipes in the prior art mainly include electrofusion connection, flange connection, capacitor bushing connection or fastener connection. Among them, the electrofusion connection has limited applicable conditions and cannot be disassembled. Although the flange connection is easy to disassemble, it is It can only realize the connection of two pipe ends. The operation process of capacitor casing connection is cumbersome and prone to breakage. Fastener connection is a commonly used connection between steel pipes and steel pipes in China. It is mostly used in constr...

[0002] The methods of connecting two pipes in the prior art mainly include electrofusion connection, flange connection, capacitor bushing connection or fastener connection. Among them, the electrofusion connection has limited applicable conditions and cannot be disassembled. Although the flange connection is easy to disassemble, it is It can only realize the connection of two pipe ends. The operation process of capacitor casing connection is cumbersome and prone to breakage. Fastener connection is a commonly used connection between steel pipes and steel pipes in China. It is mostly used in construction projects with an outer diameter of Φ48mm. Fasteners are divided into right-angle fasteners (cross fasteners, directional fasteners), rotary fasteners (movable fasteners, universal fasteners) and butt fasteners (one-word fasteners, direct fasteners) ), the right-angle fastener is mostly used for the connection of two vertically intersecting steel pipes, which rely on the friction between the fastener and the steel pipe to transmit the load; the rotary fastener is mostly used for the connection of two intersecting steel pipes at any angle, and the butt fastener is It is used for the butt joint of two steel pipes

Domestic fasteners are mostly made of cast iron, and their mechanical properties should comply with "Steel Pipe Scaffold Fasteners" (GB15831-2006). The material is not lower than KT330-08, and the applicable occasions are mostly rail and sleeper connections or scaffold connections, etc., which cannot be applied well. For the simple connection of pipelines in daily life, it is often necessary to fix or connect two pipelines in the vertical cross direction in practice. Therefore, this invention designs a new type of cross-type fixed connection buckle, which is suitable for universal use of various pipelines and has a simple structure. , Easy to use, good connection stability, good economic benefits and practical value
