Description

The positioning mechanism of the tensioner ratchet baffle

technical field

The utility model belongs to the technical field of machinery and relates to a tensioner, in particular to a positioning mechanism for a ratchet baffle of the tensioner.

Background technique

During the process of carrying goods by car, the goods must be fixed to prevent displacement and scattering. Bundling with ordinary nylon ropes or steel wire ropes is not only inefficient, but also laborious to operate; at the same time, it is also difficult to tie the goods tightly. Since the invention of the tensioner, it is convenient and safe to bind goods by means of the tightening effect of the tensioner. The tensioner can quickly and conveniently bind the goods in place, so it is widely used.

At present, the tensioners used in vehicle transportation are assembled from components such as brackets, handles, ratchets, binding straps, and belt hooks. The whole tensioner has two belt hooks, that is, a positioning belt hook and a movable belt hook. The positioning belt hook is fixedly connected with the outer end of the positioning binding belt, and the inner end of the positioning binding belt is fixedly connected on the support. The movable belt hook is fixedly connected with the outer end of the movable binding belt, and the inner end of the movable binding belt is wound on the reel, and as the reel rotates, the movable binding belt can be stretched or shortened, thereby realizing binding. There is also a locking mechanism in the tensioner that can make the ratchet rotate in one direction. The locking mechanism works like this: when the binding belt needs to be wound, the locking mechanism is opened, and the ratchet rotates together with the handle, and the The binding belt is tightened; when the handle is rotated to a certain degree, the locking mechanism is closed. At this time, the handle can be rotated but the ratchet cannot be rotated. When the handle is reversely rotated to a certain position, the locking mechanism is opened, and the ratchet rotates together with the handle. During the whole rotation process, the ratchet rotates in one direction all the time.

But the existing locking mechanism is fixedly connected on the tensioner bracket, which has the characteristics of inconvenient or difficult disassembly. When the locking mechanism is damaged during the tensioning process, it is not easy to repair or replace it, so that the entire tensioner is scrapped and resources are wasted. Especially when the spring in the locking mechanism is damaged, it is difficult to replace the spring, resulting in the scrapping of the whole tensioner.
