Problems solved by technology
Under normal circumstances, even a strong adult man needs to spend a lot of effort to loosen and fasten the fixing nut of the tire, and at the same time remove the whole bad tire to replace the spare tire, which is very laborious
For the weak, it is impossible to complete the above operation of replacing the spare tire without the help of equipment
In cities, there are many paths for car repairs and it is very convenient; but if it occurs in the wilderness or remote rural mountainous areas, the waiting time for repairs is very long and the road is long

Embodiment Construction
[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 as well as Figure 8 As shown, a portable tire installation and dismounting device disclosed in the present invention includes a long sleeve 4, a torque adjustment structure and a tire transport frame. The torque adjustment structure includes a first housing 51, a second housing 52, a driving pulley 7, an intermediate Pulley 8, driven pulley 9, and nut cover 13. It should be noted that, in this case, the effective working radius of the driving pulley 7 should be smaller than the effective working radius of the driven pulley 9, that is, to play the function of increasing the torque. And for the intermediate pulley 8, such as Figure 4 As shown, two belt grooves are arranged side by side on the intermediate pulley 8, which are respectively the first belt groov...

The invention discloses a portable tire mounting and dismounting device which comprises a long sleeve, a moment adjusting structure and a tire conveying frame. The torque adjusting structure comprisesa first shell, a second shell, a driving belt wheel, a middle belt wheel and a driven belt wheel. The working radius of the driven belt pulley is greater than that of the driving belt pulley; a V-shaped hanging block and a polygonal protruding column are arranged in the center of the wheel face of the driving belt wheel, U-shaped reverse bending parts are formed at the two ends, away from the driving belt wheel, of the V-shaped hanging block, a nut sleeve is arranged in the center of the driven belt wheel, and the nut sleeve and the driven belt wheel are fixedly connected or integrally formed. The tire transportation frame is of a rectangular frame structure and is formed by connecting two adjusting rods and two horizontal rods. Universal wheels are fixedly installed at the ends, close tothe horizontal rods, of the adjusting rods. By means of the portable tire mounting and dismounting device, spare wheel replacement operation is quite labor-saving, and the portable tire mounting anddismounting device is suitable for most drivers including weak people.
Description
technical field [0001] The invention relates to a portable tire installation and removal device. Background technique [0002] If a car tire fails on the road, it is generally necessary to replace the spare tire. In general, even a strong adult man needs to spend a lot of effort to loosen and fasten the fixing nut of the tire, and take off the whole bad tire to replace the spare tire at the same time, which is very laborious. For the weak, the above-mentioned operation of changing the spare tire cannot be completed at all without the aid of equipment. In the city, there are many paths for car repair and it is also very convenient; but if it occurs in the wilderness or remote rural mountainous areas, the waiting time for repair is very long and the road is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable tire installation and removal device, which is very labor-saving to replace the spare tire, a...
