Problems solved by technology

[0005] It can be seen that although the above-mentioned tensioner can realize fast belt retraction, since the brake baffle and the large baffle are hinged on the frame and the handle, such a structure may cause the brake baffle to be stuck during the swing process. The phenomenon that affects the normal use of the tensioner

Embodiment Construction

[0031] like figure 1 and figure 2 As shown, this automatic take-up tensioner is made up of belt shaft 2, support 1, handle 3, blocking assembly one 4, blocking assembly two 5 and scroll spring 6 etc., and it is a kind of device for binding goods.

[0032] The handle 3 is hinged on the bracket 1 through the belt shaft 2 , that is to say, the two ends of the belt shaft 2 are respectively connected to both sides of the bracket 1 , and the belt shaft 2 can rotate relative to its joint with the bracket 1 . On the belt shaft 2, a binding belt for binding goods is also wound.

[0033] A blocking component 1 4 capable of abutting against the ratchet 9 is provided on the bracket 1 , and a blocking component 2 5 capable of abutting against the ratchet 9 is provided on the handle 3 . Blocking assembly one 4 comprises blocking piece one 4a, spring one 4b and the guide hole one 1a that is arranged on the bracket and is bar-shaped, and blocking piece one 4a is positioned at guide hole on...

Abstract

The invention provides an automatic take-up tensioner, belongs to the technical field of machinery, and solves the problem that a brake baffle may be stuck when the conventional automatic take-up tensioner swings. The automatic take-up tensioner comprises a belt axis, a bracket, a handle, a barrier component 1 and a barrier component 2, wherein a swirling spring is arranged between the bracket and the belt axis; the belt axis has a trend of moving to the direction of winding a binding strap under the action of the swirling spring; and the barrier component 2 is fixedly connected with a damping mechanism which acts on ratchet wheels. When the tensioner is in an ungirding state, the damping mechanism acts on the ratchet wheels, and the damping force of the damping mechanism is greater than the elastic action force of the swirling spring, thus, the damping mechanism can eliminate the damping force against the ratchet wheels through exogenous action. The automatic take-up tensioner has the advantages of low cost, little occupied space, high using stability and compact and beautiful structure.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a tensioner for bundling goods, in particular to an automatic belt tensioner. Background technique [0002] Tensioners are widely used as a binding tool. During use, especially when large-scale goods are bundled, since the strapping straps are relatively long, the strapping is cumbersome and the strapping efficiency is relatively low. [0003] In order to solve the above problems, Chinese patent CN2936490Y provides an "automatic take-up tensioner", which is composed of a casing and a handle hinged on the casing through a main shaft, and a large gear is respectively arranged on the handle and the casing. The plate assembly and the small baffle assembly are also provided with a brake baffle in addition, and the effect of the brake baffle is to realize fast or slow speed take-up. [0004] The brake baffle of the above-mentioned patent is hinged on the casing, and the large baffle ...
