Chain tensioner

Abstract

The invention provides a chain tensioner, belongs to the technical field of machines, and solves the problem that a large commodity is bundled at low stability by a rope similar to a ribbon of the conventional tensioner. The chain tensioner consists of a body, a handle, a tooth blocking plate, a pull handle, a chain and a rotating shaft, wherein the body is connected with a hook 1; the handle is hinged to the body through the rotating shaft; the rotating shaft is fixedly connected with a ratchet wheel; the tooth blocking plate is movably connected to the body and embedded into the ratchet wheel; the pull handle is movably connected to the handle and embedded into the ratchet wheel; the middle part of the chain is positioned in the body and wound on the rotating shaft; the two ends of the chain stretch out of the body; one end of the chain is fixedly connected with a hook 2; a spring capable of making the tooth blocking plate tend to be pressed against the ratchet wheel is arranged between the tooth blocking plate and the body; the body is provided with a positioning piece; the two ends of the spring act on the positioning piece and the tooth blocking plate; and due to a separationstructure of the positioning piece and the body, the body and the positioning piece are easy to process.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a tensioner for binding goods, in particular to a chain tensioner. Background technique [0002] During the transportation of goods by car, train, ship, etc., the goods often need to be bundled to prevent damage or loss of the goods due to bumps, vibrations or collisions during transportation. The tensioner is a commonly used binding device in the transportation of goods. Usually, the goods are bound with webbing, and then the webbing is tightened by the tensioner to bind the goods tightly. [0003] The existing tensioner mainly includes a body, a handle, a webbing and two hooks. The hook is arranged on the webbing, and the body is provided with a one-way rotation mechanism. Turn the handle of the tensioner back and forth to tighten the webbing to achieve the purpose of binding the goods. However, for some goods with large volume and quality, ordinary webbing is easy to slide, ...

AI Technical Summary

Problems solved by technology

However, it still uses ropes similar to webbing, and there is still a problem of low binding stability for some goods with large volume and quality.

[0005] At the same time, the body of the existing tensioner has an integrated structure, which makes the body have more heterogeneous structures, and the processing of the body is very inconvenient
