Technical Field

The utility model relates to a caster, in particular to a caster with adjustable height.

Background

A caster is a fitting mounted on the bottom of a device, and is commonly used for carts, medical carts, furniture, mechanical devices, and the like. With the development of the times, more and more devices need to use casters, which become an indispensable component of mobile devices.

But height-adjusting's truckle on the market at present needs just can adjust the height of truckle when light load or empty load, especially under the heavy load condition, and unable height-adjusting need lift up equipment just can adjust, and it is very inconvenient to use.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides the caster with adjustable height during heavy load.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a but height-adjusting's truckle, including mount pad, altitude mixture control spare, axle spare and with the axle spare rotate the wheel body of being connected, the mount pad is provided with mounting structure, altitude mixture control spare mainly comprises four linking arms, two regulating plates and a stay bolt, four the linking arm surrounds into rhombus shape, two of lower part the linking arm is articulated with the axle spare respectively, two on upper portion the linking arm is articulated with the mount pad, and upper and lower two are adjacent it has the regulating plate, one of them the regulating plate is provided with the screw hole, another the regulating plate is provided with the through-hole corresponding with the screw hole, two the regulating plate passes through stay bolt and connects, the head of stay bolt is inconsistent with the regulating plate that is provided with the through-hole.

The bottom of mount pad is provided with the stabilizer blade, the quantity of stabilizer blade is four.

The section of the supporting leg is L-shaped.

And the bottoms of the supporting legs are provided with anti-slip pads.

The shape of linking arm is "H" font, the axle spare comprises axis of rotation and two fixed blocks, the axis of rotation is connected with the wheel body rotation, the fixed block rotates respectively and connects in the both ends of axis of rotation, the fixed block respectively with two of lower part the linking arm is articulated.

The joint of the long bolt and the through hole is a smooth cylindrical surface.

The utility model has the beneficial effects that: compared with the existing caster wheel which can only adjust the height in no-load or light-load, the adjustable-height caster wheel is simple and reliable in structure, can adjust the height and is strong in load. The height of the utility model can be adjusted when heavy load is carried; by arranging the support legs and the anti-slip mat, the anti-slip shoe is more stable in a stop state, is not easy to slip and cannot scratch the ground; by arranging the cylindrical surfaces, the abrasion of the long bolts to the through holes is reduced, so that the service life of the utility model is longer.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is an exploded view of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the equipment or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

Referring to fig. 1 to 2, a caster with adjustable height comprises a mounting base 1, a height adjusting member, a shaft member, and a wheel body 2 rotatably connected with the shaft member. The mounting base 1 is provided with a mounting structure 11, the mounting structure 11 may be a directional or universal fixing structure, and in this embodiment, the mounting structure 11 is four through holes. The height adjusting member is mainly composed of four connecting arms 3, two adjusting plates 4 and a long bolt 5. The four connecting arms 3 are enclosed into a rhombus shape, the two connecting arms 3 at the lower part are respectively hinged with the shaft piece, the two connecting arms 3 at the upper part are hinged with the mounting seat 1, and the adjusting plate 4 is hinged between the two adjacent connecting arms 3. One of the adjusting plates 4 is provided with a threaded hole 41, and the other adjusting plate 4 is provided with a through hole 42 corresponding to the threaded hole 41. The two adjusting plates 4 are connected through a long bolt 5, and the head of the long bolt 5 is abutted to the adjusting plate 4 provided with a through hole 42. The long bolt 5 can be used in cooperation with a twisting tool. In this embodiment, by rotating the long bolt 5, the two adjusting plates 4 can be moved closer to or away from each other, so as to raise or lower the wheel body 2.

Compared with the existing caster capable of adjusting the height only in no-load or light-load conditions, the caster has the advantages of simple and reliable structure, adjustable height and strong load. And the height of the embodiment can be adjusted when heavy load is carried out.

The bottom of the mounting seat 1 is provided with four support legs 12, and the number of the support legs 12 is four. The wheel body 2 can be retracted into the supporting leg 12, so that the supporting leg 12 is abutted against the ground, and the stopping state of the present embodiment is more stable and is not easy to slip.

The cross-section of the support leg 12 is L-shaped, so that the support leg 12 is not easy to deform and has strong loading capacity.

The bottom of the support leg 12 is provided with a non-slip pad 6, and the non-slip pad 6 is made of non-slip rubber. In this embodiment, the anti-slip pad 6 is detachable, and is convenient to replace after being worn. The anti-slip property of the present embodiment is improved while preventing the legs 12 from scratching the ground.

The shape of linking arm 3 is "H" font, makes linking arm 3 bearing stronger, is difficult to warp, can prevent moreover that linking arm 3 from leading to the fact the interference to wheel body 2, makes this embodiment structure compacter, and the volume is littleer. The shaft member is composed of a rotating shaft 7 and two fixing blocks 8. The rotating shaft 7 is rotatably connected with the wheel body 2, and the fixing blocks 8 are rotatably connected to two ends of the rotating shaft 7 through bolts respectively. The fixed block 8 is hinged with the two connecting arms 3 at the lower part respectively. The fixed block 8 is easy to install, and can prevent the wheel body 2 from shaking left and right, so that the embodiment can rotate more smoothly.

The joint of the long bolt 5 and the through hole 42 is a smooth cylindrical surface 51. The abrasion of the long bolt 5 to the through hole 42 is reduced, so that the service life of the embodiment is longer.

The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
