Embodiment Construction

[0029] As shown in Fig. 1 and Fig. 2, the tensioner is used to bind the goods on the motor vehicle to prevent the goods from being shifted or scattered. It includes a body 1 with a cavity inside, a rotatable reel 2 is arranged in the body 1, a chain 3 is wound on the reel 2, and a hook 4 is arranged at the outer end of the chain 3 . Another hook 4 is fixedly connected to the body 1 .

[0030] The reel 2 is provided with a worm wheel 5 fixedly connected thereto, and a rotatable worm 6 is also provided in the body 1 , the inner end of the worm 6 is hinged in the body 1 , and the outer end of the worm 6 passes through the body 1 . A clutch mechanism is provided between the worm 6 and the body 1 .

[0031] As shown in FIG. 3 and FIG. 4 , the clutch mechanism includes a strip-shaped positioning hole 11 opened on the body 1 and a positioning rod 7 disposed in the body 1 . The positioning hole 11 is located at the side of the worm 6 and it is arranged along the swinging direction o...

Abstract

The invention provides a tensioner, belonging to mechanical technical field. The invention solves the problems of the existing tensioner of complex structure and inconvenient application, etc. The tensioner comprises a body where a rotatable reel is arranged; the rotatable reel is provided with a chain; the external end of the chain is provided with a pothook; the body is fixedly connected with another pothook; the rotatable real is also provided with a worm wheel and a worm which can be rotated; the worm and the worm wheel are engaged and the external end of the worm extends out of the body. The tensioner has small occupying space and is convenient for carrying and storage. Owning to the transmission of the worm wheel and the worm, the reel is rotated and the goods are bound; therefore, the invention has simple structure. Furthermore, owning to a clutch mechanism arranged between the worm rod and the body, the worm wheel and the worm are engaged by the clutch mechanism when the goods are bound, thus ensuring simple and convenient application and saving time and effort.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a tensioner for binding goods or hanging goods. Background technique [0002] The goods on the motor vehicle must be fixed during transportation to prevent displacement and scattering. When binding the goods on the motor vehicle, tools such as tensioners are often used to bind the goods, which will put forward higher requirements for the stability of the tensioner. [0003] Existing tensioners usually include a body, a reel mounted in the body, a chain wound on the reel, and a hook on the chain. Another hook is also fixedly attached to the body. When the goods need to be bundled, the chain can be gathered by turning the reel, and of course, the goods are tightly bound like this. [0004] It can be seen that after the reel rotates, it must be positioned, so as to prevent the bundled goods from shifting and falling apart. In order to achieve the above-mentioned purpose, people ...
