Galvanized steel pipe special clamp capable of realizing simultaneous internal and external clamping

Abstract

The invention discloses a galvanized steel pipe special clamp capable of realizing simultaneous internal and external clamping, and relates to the technical field of galvanized steel pipes. The clampcomprises a fixing frame, wherein a clamping groove is formed in the middle of the fixing frame, a rotating block is rotationally connected to the inner bottom wall of the fixing frame, and an inclined block I in sliding connection with the inner side of the rotating block is movably connected to the middle of the fixing frame. According to the galvanized steel pipe special clamp capable of realizing simultaneous internal and external clamping, a clamping block I is used in cooperation with a clamping block II, when a galvanized steel pipe is clamped, the steel pipe is inserted into the clamping groove, after insertion of the steel pipe, a hand wheel is rotated, at the same time, the clamping block I extends out of the fixing frame and moves towards the middle of the fixing frame, meanwhile, the clamping block II can extend out of the fixing frame and move towards the outer side of the fixing frame, the clamping block I and the clamping block II are in contact with the outer side and the inner side of the steel pipe respectively, in addition, the internal and external surfaces of the steel pipe are clamped at the same time, so that the effect of simultaneous internal and external surface clamping is achieved, the clamping effect is enhanced, meanwhile, the steel pipe can be prevented from being recessed through clamping by the clamp, and clamping is more tight.

Description

technical field [0001] The invention relates to the technical field of galvanized steel pipes, in particular to a special clamp for galvanized steel pipes that clamps inside and outside at the same time. Background technique [0002] Galvanized steel pipe is a welded steel pipe with hot-dip galvanized or electro-galvanized surface. The main purpose of galvanizing is to improve the corrosion resistance of the steel pipe and prolong the service life of the steel pipe. A tensile test will be performed on the galvanized steel pipe before use to verify the steel pipe Whether it meets the standard or not, when carrying out the tensile test, it is necessary to fix the galvanized steel pipe with a special clamp to facilitate stretching. However, the current galvanized steel pipe clamp has the following problems in use: [0003] Most of the current galvanized steel pipe clamps are fixed-size clamps, which can only clamp the same type of galvanized steel pipe. However, there are many ...

AI Technical Summary

Problems solved by technology

[0003] Most of the current galvanized steel pipe clamps are fixed-size clamps, which can only clamp the same type of galvanized steel pipe. However, there are many types and specifications of galvanized steel pipes. The current clamps cannot meet the needs of use, so there is an urgent need for a clamp that can Fixtures for holding steel pipes of different specifications;
