Abstract

The utility model relates to a wheel body structure which is provided with a body provided with a first frame part and a second frame part connected together, wherein a wheel body is pivoted on the second frame part via a pivot shaft. A lifting structure arranged in the body is composed of a driving shaft, a driven shaft and a base cushion block, wherein one end of the driving shaft is provided with an operator part and the driving shaft transversally penetrates and pivots on the first frame part. The outer circumference of one section of the driven shaft interlocked by the driving shaft is provided with an outer thread part on which the base cushion block is screwed. The driven shaft longitudinally penetrates and pivots on the first frame part. Via the rotation of the driving shaft, the driven shaft rotates, so that the base cushion block moves up and down. The utility model with the advantages of convenient operation and safe and convenient operation can not move after a trolley is positioned, and can effectively position the trolley.

This body is installed a lifting structure, and this lifting structure is made up of an imput shaft, a driven axle and a heelpiece piece;

One end of this imput shaft has an operating portion, and pivot is laterally worn in this first frame portion by this imput shaft system;

This driven axle is able to by this imput shaft interlock, and one section outer peripheral edges of this driven axle are provided with an external thread part, this external thread part must be established for this heelpiece piece spiral shell, this driven axle is then vertically worn pivot in this first frame portion, be able to rotation by this imput shaft, make this driven axle rotation, and then make this heelpiece piece upper and lower displacement.

What deserves to be mentioned is that a side of this first frame portion is convexly equipped with out the projection of a hollow, this projection is ccontaining for the operating portion of this imput shaft.

Wherein, one of this imput shaft end has a bevel gear part, and the nearly stage casing desired location of this driven axle, have one can with the bevel gear part of the bevel gear part toe joint of this imput shaft.

Wherein, this operating portion is an inner hexagonal hole.

A kind of body structure of taking turns of the utility model, its advantage is: manipulate safe ready, can displacement behind the go-cart location, can actv. location go-cart.

＜five〉specific embodiment

At first, please cooperate and consult Fig. 1 to shown in Figure 6, a kind of body structure of taking turns of the utility model, it comprises:

One body 10, this body 10 has the first frame portion 11 of a hollow, the lateral margin desired location of this first frame portion 11, be wholely set a section and generally be the hollow second frame portion 12 of ㄇ shape, this second frame portion 12 must be pivoted a wheel body 20 for a pivot 21, and a side of this first frame portion 11 is convexly equipped with out the projection 111 of a hollow, and the end face of this first frame portion 11 flat jam plate 13 that is pivoted, and this jam plate 13 is locked in the plate body A1 bottom surface (shown in Fig. 4,5) of a go-cart A;

One lifting structure 30, this lifting structure 30 is formed (as shown in Figure 1) by an imput shaft 31, a driven axle 32 and a heelpiece piece 33;

One end of this imput shaft 31 has a bevel gear part 311, and this imput shaft 31 has an operating portion 312 that must utilize tool operation for the user with respect to the other end of this bevel gear part 311, and this imput shaft 31 is laterally to wear pivot in this first frame portion 11, makes the operating portion 312 of this imput shaft 31 be positioned at this projection 111 (shown in Fig. 2 shows);

The nearly stage casing desired location of this driven axle 32, has a bevel gear part 321 (as shown in Figure 3) that is able to bevel gear part 311 toe joints of this imput shaft 31, and one section outer peripheral edges of this driven axle 32 are provided with external thread part 322, this external thread part 322 must be established for these heelpiece piece 33 spiral shells, and this driven axle 32 is vertically worn the centre of pivot in this first frame portion 11, and be able to rotation by this imput shaft 31, make this driven axle 32 rotations, and then make of external thread part 322 upper and lower displacements (as shown in Figure 6) of this heelpiece piece 33 in this driven axle 32.
