PE pipe fastening clamp

Abstract

The invention discloses a PE pipe fastening clamp. Two V-shaped supporting frames are arranged on a base, and a sleeve is arranged on a connecting rod between the two supporting frames; a pin shaft isfixed to the inner wall of the sleeve; the connecting rod is connected through another pin shaft to form a rear hinging point; a shock-resistant spacer is arranged on one side of the middle of a cross beam of the base, and the gravity center of the shock-resistant spacer is fixed through a gravity center shaft; springs are arranged at the hollow parts, penetrated by an adjusting rod connected tothe gravity center shaft, of the supporting frames and abut against the inner end faces of the hollow parts of the supporting frames; a horizontal transverse rod is arranged at the lower end of a control rod of a pair of calipers and provided with a lifting rod in the mode of penetrating through a thread through hole; and the lifting rod and a thread in the thread through hole are matched mutually. The effectiveness of overall fixing of the clamp is ensured, the clamping requirement of pipes of multiple specifications is met, damage to the outer walls of the pipes is further avoided while theclamping degree is ensured, buffer resistance is strengthened, certain impact resistance is achieved, and the adjusting rod can adjust the clamping pipe diameter rapidly.

Description

technical field [0001] The invention belongs to the technical field of fastening fixture equipment, and in particular relates to a PE pipe fastening fixture. Background technique [0002] PE pipe is polyethylene plastic, the most basic kind of plastic, plastic bags, plastic wrap, etc. are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. [0003] Welding of PE pipes, butt welds of PE pipes, this method offers the highest reliability and a range of diameters and pressures Process: the ends of the pipes are heated, using a tool called "mirror image" under the definition of contact pressure and temperature ". The ends are quickly touched and kept under pressure during cooling. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. According to the w...

Problems solved by technology

The disadvantage is that the equipment is not as good as PE pipes. During the construction, special attention should be paid to the safe distance of thermal heating, and it should not be exposed to sunlight in the air, and it is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.

[0004] When PE pipe is processed, there will be a process, that is, cutting the pipe edge of PE pipe, and the pipe positioning device often uses clamps, and the clamping surface of this type of clamp does not completely fit the pipe wall , so it will affect the clamping effect; or it may cause scratches on the surface of the pipe wall due to excessive clamping force; there is also a pipe clamp that has a better clamping effect, but the device is too complicated, resulting in an increase in cost. And the generality is not strong
