Embodiment 1

[0026] Embodiment one: see figure 1 — Figure 9 , a spare tire fixing device, including a winch mechanism 1, a wire rope 2 and a spare tire support mechanism 3, considering the distance between the winch mechanism and the spare tire support mechanism and the protection of the wire rope, a wire rope is also installed on the winch mechanism Sleeve 4, one end of this wire rope sleeve is fixed on one side of winch mechanism housing, and its other end 5 is fixed on the car body.

[0027] The winch mechanism 1 includes a housing 13, and a pin shaft 7 is installed through the housing, and a female joint 6 is set on the lower end of the pin shaft. The head matches the prismatic structure, and the female joint is located in the upper end of the housing, and a pressure plate 8 is fixedly set on the outer side; at the same time, an eccentric wheel 15 is movably set on the pin shaft on the upper side of the pressure plate, and a rotating set is set on the outer side of the eccentric whee...

Abstract

The invention relates to a spare tire fixing device which comprises a winch mechanism, a steel wire rope and a spare tire support mechanism, wherein the steel wire rope stretches into a shell from one side of the winch mechanism shell and is wound on a steel wire rope winch, the shrinkage and the extension of the steel wire rope can be realized through a mechanical motion of internal parts of the winch mechanism so as to finish the rise and the drop of a spare tire. The winch mechanism has a slip characteristic and gives a slip feedback to a user after the spare tire is well fixed, therefore, the damage to the winch mechanism caused by misoperation can be avoided. The spare tire support mechanism can be partially assembled and disassembled, which is convenient for assembling and disassembling the spare tire. The spare tire fixing device provided by the invention has the advantages of spare tire fixing reliability, transmission stability, operation portability and low noise and is superior to the traditional chain-type spare tire fixing device on performances in multiple aspects.

Description

[0001] technical field [0002] The invention relates to a spare tire fixing tool, in particular to a spare tire fixing device. Background technique [0003] The vast majority of spare tire fixing devices on domestic commercial vehicles are chain-type spare tire fixing devices at present. It is mainly composed of a rotating shaft, a sprocket, a chain ring, an eccentric wheel, a housing and a spare tire supporting part, and has a relatively simple structure. The rotation of the sprocket is driven by the movement of the eccentric wheel, so as to realize the rise and fall of the chain ring. [0004] The disadvantage of this type of mechanism is that the transmission process is not stable, the chain is easily stuck during the transmission process, and the operator can only fix the spare tire by feeling, which is laborious and noisy. Contents of the invention [0005] In order to overcome the deficiencies in the prior art, the invention provides a spare tire fixing device. ...
