Problems solved by technology

[0002] In terms of chain tensioning, there are many structural forms at home and abroad, generally in the form of direct binding, which is prone to slack and looseness, and the chain is easy to get stuck after being stressed. Even if the chain is equipped with a hook, it is impossible to adjust the chain. The effective length of the chain can not be tightened
This brings the actual use is very inconvenient, and easy to be restricted by external conditions

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0013] Such as figure 1 , 2 , Shown in 3, a kind of chain tightening device comprises hook (1), connector (2), stepping up handle (3), connecting arm (4), connecting block (5) and limit block (6). Among them, the hook (1) is fixedly connected to the left end of the connecting piece (2), and the connecting piece (2) is a cylinder whose front and rear parts are cut off to form an approximate ellipsoid, and the upper and lower arc surfaces of the connecting piece (2) are threaded, and the handle (3) is a ring body, the inner side of the tightening handle (3) is provided with threads, and is connected to the connector (2) through threads, and the outer side of the tightening handle (3) is provided with 4 blind holes as tightening holes. When the tightening handle (3) cannot be twisted by hand, a round bar-shaped metal body can be inserted into the tightening hole to fur...

Abstract

The invention relates to the technical field of chain tensioning, in particular to a chain tensioning device. The device comprises a hook [1], a connecting piece [2], a tightening handle [3], a connecting arm [4], a connecting block [5] and a limiting block [6]. A chain is tensioned and integrated in the simple device, the cost is reduced, the reliability is high, and the rapid tensioning of the chain is realized. The device is simple, firm, high in reliability and convenient to use and is not limited by external conditions.

Description

technical field [0001] The invention relates to the technical field of chain tensioning, in particular to a chain tensioning device. Background technique [0002] In terms of chain tensioning, there are many structural forms at home and abroad, generally in the form of direct binding, which is prone to slack and looseness, and the chain is easy to get stuck after being stressed. Even if the chain is equipped with a hook, it is impossible to adjust the chain. The effective length of the chain will cause the chain to fail to tighten. It is very inconvenient to bring practical use like this, and is easily restricted by external conditions. Contents of the invention [0003] The purpose of the present invention is: [0004] The invention provides a chain tensioning device for chain tensioning, which is suitable for fast chain tensioning. [0005] Technical scheme of the present invention is: [0006] A chain tensioning device, comprising a hook (1), a connecting piece (2),...
