Problems solved by technology

[0002] Known jack rear wheel structure as shown in Figure 1, it is a kind of rear wheel structure that is used in horizontal jack (or claims " warehouse type jack "), and its composition comprises a support 10 and straight shaft 20, and this support 10 combines A rotatable wheel 30, the straight shaft 20 runs through the rear wheel top cover 40 of the jack, and is fixedly screwed with a nut 50, and a group of known ball bearings 60 are arranged on the bracket 10, so that the wheel 30 can rotate freely; The rear wheel composition of the above-mentioned known horizontal jack has relatively high requirements on welding and manufacturing, but it is still difficult to avoid the unevenness of the four wheels, especially after the jack has been used for a long time, it will produce certain permanent deformation and cause The unevenness of the four wheels, if the unevenness of the four wheels occurs, the impact force on the ground will of course be relatively large during the process of pushing and moving the jack, which will not only easily damage the ground plane, but also cause damage to The noise is bound to be louder

Embodiment Construction

[0011] The technical solution, features and advantages of the present invention are described in detail below in conjunction with the accompanying drawings:

[0012] As shown in Figure 2, the jack wheel with the shock absorber proposed by the present invention is specially used for the attached wheel of the jack, and is especially suitable for providing the combined composition of the rear wheel top cover 5 of the known horizontal jack, so that the horizontal The rear wheel part of the formula jack has a shock-absorbing effect, which can be automatically telescopically adjusted and engaged with the sticking touch of the ground, so as to achieve the purpose that the four wheels (comprising two front wheels 61 and two rear wheels 71) keep on the ground all the time.

[0013] As shown in Figure 3, the composition of the present invention mainly includes a bracket 1, a straight shaft 2, a compression spring 3 and a shaft sleeve 4; wherein:

[0014] Bracket 1, which is the same as ...

Abstract

A wheel with vibration-damping mechanism for the back wheel of horizontal jack is composed of a supporter, a compression spring, a wheel axle inserted in said compression spring, and an axle sleeve in which said compression spring and wheel axle are arranged.

Description

technical field [0001] The invention relates to a jack wheel, in particular to a shock-absorbing rear wheel structure which is very suitable to be used in combination with the top cover of the rear wheel of a horizontal jack. Background technique [0002] Known jack rear wheel structure as shown in Figure 1, it is a kind of rear wheel structure that is used in horizontal jack (or claims " warehouse type jack "), and its composition comprises a support 10 and straight shaft 20, and this support 10 combines A rotatable wheel 30, the straight shaft 20 runs through the rear wheel top cover 40 of the jack, and is fixedly screwed with a nut 50, and a group of known ball bearings 60 are arranged on the bracket 10, so that the wheel 30 can rotate freely; The rear wheel composition of the above-mentioned known horizontal jack has relatively high requirements on welding and manufacturing, but it is still difficult to avoid the unevenness of the four wheels, especially after the jack h...
