The utility model adopts the following technical solution:

A kind of universal wheel, including support base, wheel seat, wheel, wheel seat are hollow cylindrical structure, and the top of wheel seat is equipped with Connecting plate；The inside of wheel seat lower end is equipped with the ball seat for the spherical shell shape that Open Side Down, and spherical wheel is inlaid in ball seat；Take turns seating In in hollow support base, the upper end of support base is equipped with terminal pad, and the lower part of support base is equipped with supporting leg, the lower end of guide post and company Fishplate bar is affixed, and the upper end of guide post passes through guide plate, and guide plate is affixed with support base, and guide post is connect with elevating mechanism.

Compared with prior art, beneficial effect is the utility model by adopting the above technical scheme:

Structure is simple, compact, turns to flexibly, long service life is at low cost.

Further, the prioritization scheme of the utility model is:

Elevating mechanism includes handle, guide post, the first pin shaft and the second pin shaft, and the middle part of support base side is equipped with vertical Elongated slot, handle are placed in elongated slot, and the inner end of handle is column articulated by the first pin shaft and guiding, and the middle part of handle passes through the second pin shaft With support seat hinge, the inner end of handle is that U-shaped pitches structure.

The material of ball seat is copper, babbit or nylon.

The material of wheel is nylon, polyurethane, rubber or cast iron.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the embodiments of the present invention.

In figure: wheel 1；Wheel seat 2；Ball seat 3；Connecting plate 4；Support base 5；Guide post 6；Guide plate 7；First pin shaft 8；Handle 9；Second pin shaft 10；Supporting leg 11；Terminal pad 12.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

Refering to fig. 1, the present embodiment is a kind of universal wheel, by wheel 1, wheel seat 2, ball seat 3, connecting plate 4, support base 5, guiding Column 6, guide plate 7, the first pin shaft 8, handle 9, the second pin shaft 10, supporting leg 11 and terminal pad 12 are constituted, during the middle and upper part of wheel seat 2 is Empty cylindrical structure, the lower part of wheel seat 2 are hollow cone, and fishplate bar 4 in succession are welded on the top of wheel seat 2.

The interior welds of 2 lower end of wheel seat have ball seat 3, and ball seat 3 is spherical shell shape, and Open Side Down for ball seat 3, the material of ball seat 3 It is copper, babbit or nylon.Wheel 1 is inlaid in ball seat 3, and wheel 1 is spherical shape, and wheel 1 and ball seat 3 cooperate, wheel 1 Lower surface is higher than the lower end surface of wheel seat 1.The material of wheel 1 is nylon, polyurethane, rubber or cast iron.

Wheel seat 2 is mounted in hollow support base 5, and wheel seat 2 can move up and down in support base 5, the upper end of support base 5 It is welded to connect disk 4, the outer circumference surface of 5 lower part of support base welds three supporting legs 11.The lower end of guide post 6 and connecting plate 4 weld, and lead It is circle to the section of column 6, the upper end of guide post 6 passes through the center of guide plate 7, and guide plate 7 is placed in the top in support base 5, The inner peripheral surface of guide plate 7 and support base 5 welds.

The middle part of support base 5 is equipped with elevating mechanism, and elevating mechanism is by handle 9, guide post 6, the first pin shaft 8 and the second pin shaft 10 are constituted, and are machined with vertical elongated slot in the middle part of 5 side of support base, and handle 9 is placed in the elongated slot, and the inner end of handle 9 passes through the One pin shaft 8 and guide post 6 are hinged, and the inner end of handle 6 is that U-shaped pitches structure, and the middle part of handle 9 passes through the second pin shaft 10 and support base 5 is hinged.

The use process of the present embodiment is: the present embodiment being mounted on to the lower part of chair legs or stool leg, needs mobile chair When son or stool, handle 9 being moved upwards, moves down guide post 6, guide post 6 drives wheel seat 2 to move down, and wheel 1 exposes The lower end surface of support base 5, after supporting leg 11 rises, movable stool or chair；After being moved to designated position, handle 9 is moved downwards, is led Moved up to column 6, guide post 6 drive wheel seat 2 move up, wheel 1 retract, supporting leg 11 and ground face contact, support chair or Stool.The utility model using flexible, torque needed for turning to is small, and steering is laborsaving, and structure is simple, easy to maintain, long service life.

The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model Sharp range, it is all with the variation of equivalent structure made by the utility model specification and accompanying drawing content, it is both contained in the utility model Interest field within.
