Problems solved by technology
[0006] Obviously, the above-mentioned binding device can realize the control of the belt shaft, but the worm is pulled by the operator, and the operation is cumbersome
At the same time, after the worm is separated from the worm wheel, since the worm is not positioned, the worm will touch the worm wheel, which will not only make the winch make noise during use, but also cause premature wear of the teeth of the worm and worm wheel, reducing the use of life

Embodiment Construction
[0038] Such as figure 1 As shown, the tightener has a support 1 on which a rotatable belt shaft 2 is provided, and one end of the belt shaft 2 stretches out from the support 1 .
[0039] Such as figure 2 with image 3 As shown, a housing 3 with a cavity inside is fixedly connected to the side of the bracket 1, and the belt retracting device of the tightener is arranged at the housing 3. This device comprises parts such as worm screw 4, worm screw shaft 4b, worm wheel 5 and rotary sleeve 7.
[0040] The worm 4 is sleeved on the worm shaft 4b and the worm 4 and the worm shaft 4b are fixedly connected together.
[0041] The worm wheel 5 is fixedly connected to the extended end of the belt shaft 2, and the worm shaft 4b is also arranged in the housing 3. The worm shaft 4b is located at the side of the worm wheel 5 and one end of the worm shaft 4b passes through the housing 3, and is outside the worm shaft 4b. There are several teeth 4a arranged axially along the worm shaft 4b...

The invention provides an improved belt-retracting device for a tightener, which belongs to the technical field of machinery. The device solves the problems that the prior belt-retracting device for the tightener is time and labor consuming in operation, inconvenient in use, short in service life, and the like. In the improved belt-retracting device, a bracket of the tightener is provided with a rotatable belt shaft of which one end extends out of the bracket. The device comprises a case body which is fixedly connected with the side part of the bracket, and a worm, a worm shaft and a worm wheel which are arranged inside the case body, wherein the worm is fixedly connected with the extending end of the belt shaft; the worm shaft is arranged on the side part of the worm wheel and can move in the case body along the axial direction; the worm is sleeved on and fixedly connected with the worm shaft; the external end of the worm shaft extends out of the case body; a guiding mechanism is arranged between the worm shaft and the case body and can make the worm shaft move along the axial direction of the case body when the worm shaft rotates; and when the worm shaft is rotated and moves along the axial direction, the worm is meshed with the worm wheel and the worm shaft is separated from the guiding mechanism. The belt-retracting device has the advantages of simple structure, and high use stability and reliability.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to a winch and a winch for bundling goods in the process of logistics transportation, in particular to a belt retracting device for a belt shaft in the winch. Background technique [0002] During the transportation of the goods, in order to prevent loss or damage caused by falling off or collision. It is difficult to fasten the goods firmly with the ordinary rope binding method, and it is easy to cause the goods to loosen, which is time-consuming and labor-intensive. A winch is an advanced lashing tool. [0003] Chinese patent literature discloses a kind of quick rotation manual winch device [publication number: CN2846294Y], and this device comprises reel shaft, end cap, ratchet device, back-stop device etc. One end of the reel shaft is equipped with a ratchet device, and the end cap is installed on the other end of the reel shaft through the stop device. The backstop device can ...
