Automatic tightening winch

Abstract

The invention discloses an automatic tightening winch, and relates to the technical field of winches. According to the technical scheme, the automatic tightening winch is characterized by comprising amounting frame, a motor and a winch barrel, wherein a cable is wound on the winch barrel; a traction main body is arranged on the mounting frame; a movable mechanism and a pressing piece are arrangedon the traction main body; the movable mechanism comprises a roller and a driving piece; the roller is rotationally connected into the traction main body; the driving piece is arranged on the traction main body; the cable penetrates through the position between the roller and the pressing piece; and the driving piece is used for driving the roller to be close to or away from the pressing piece. The motor drives the winch barrel to rotate, so that the cable is recycled; when the driving piece on the traction main body drives the roller to be close to the pressing piece, the cable is pressed bythe pressing piece and the roller, the cable between the traction main body and the winch barrel is always kept in tension, and the recycled cable can be tightly wound on the winch barrel, so that the purpose of conveniently and tightly winding the cable on the winch barrel is achieved.

Description

technical field [0001] The invention relates to the technical field of winches, in particular to an automatic tightening winch. Background technique [0002] The winch is mainly used for self-protection and traction of off-road vehicles, agricultural vehicles, yachts and other special vehicles. Electric winches play an important role when traction operations, rescue, and self-rescue in the field are required. [0003] At present, the Chinese patent whose notification number is CN201942458U discloses an electric winch. It includes an air pump, a motor, a reduction device and a winch, and it also includes a transmission mechanism. The input end of the transmission mechanism is connected to the output shaft of the motor. The output end of the transmission mechanism is located on the side of the motor, and the output end of the transmission mechanism is connected to the input shaft of the air pump. . [0004] The above technical solution has the following defects: the noose i...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution has the following defects: the noose is wrapped around the winch, and when the rope is unwound, the noose is separated from the winch and released one after another. After the noose is used, the motor needs to drive the winch to rotate so that the noose is rolled back to the winch. In order to ensure that the noose can be tightly coiled on the winch, the user needs to hold the noose and apply pressure to the side away from the winch to make the noose tense. This process brings great inconvenience to the user

[0005] In the process of retracting the noose to the winch, because the noose has no tension, the noose will not be tightened. If there is no tight noose, it will be directly rolled back to the winch, and the noose will easily loosen.

The noose rolled up in this way is not tight, which seriously affects the service life of the noose
