Self-locking strain clamp

Abstract

The invention relates to the technical field of strain clamps and discloses a self-locking strain clamp. An air hole is formed in the outer circle wall surface of a limiting block; the air hole is a circular through hole; the air hole and a blocking block are clamped together; scraping blades are fixedly mounted on five inner wall surfaces of the pentagonal through part of the air bag; the scraping blade is of a rectangular structure; scraping blocks are fixedly mounted on the wall surfaces of the sides, close to each other, of the five scraping plates; the scraping block is a hollow rectangular pyramid; the wall surface of one side, away from the scraping plate, of the scraping block is open; the scraping plate can float along with the amount of gas in the air bag; a cable is inserted into the extension frame to be fixed; the limiting block and the extension frame are clamped together, the spring extrudes the combination rod, the spring pushes the clamping block into the side hole, and the combination rod is clamped with the opposite groove through the side hole; and when the extension frame is disassembled, the motor is started, the shaft of the motor rotates to drive the main ratchet wheel to rotate, the main ratchet wheel can drive the chain to rotate, and the chain rotates to drive the auxiliary ratchet wheel to rotate.

Description

technical field [0001] The invention relates to the technical field of strain clamps, in particular to a self-locking strain clamp. Background technique [0002] Tension clamp refers to the hardware used to fix the wire to bear the tension of the wire and hang the wire to the tension string or tower; [0003] In actual use, tension clamps are divided into fixed and separate types. The separate strain clamps are detachable in actual use, but the adjusting parts of the detachable strain clamps are exposed to the outside, which is These components are easily corroded by the harsh environment externally, which makes the adjusting parts of the tension clamp unusable. For this reason, a self-locking tension clamp is needed. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a self-locking tension clamp, which has the advantages of preventing the adjustment parts from being corrod...
