Description

Castor

Technical field

The utility model belongs to a kind of wheel, more particularly to the wheel that a kind of case and bag or small handcart are used.

Background technology

The castor that case and bag or market small handcart are used, has a vertical castor post in current structure, castor post Lower end crosses out caster axle, and caster axle inserts an inner ring for bearing, and bearing outer ring puts castor body.

This structure the disadvantage is that, assembling or repair when caster axle and castor body are combined with bearing respectively, assembling Dismounting inconvenience.The bearing arrangement for being used only is changed after damaging, and is changed bearing and be increased cost.

Utility model content

The utility model provides a kind of castor, the shortcoming the purpose is to solve prior art presence, castor is assembled maintenance It is convenient, low cost.

The utility model solves the technical scheme that its technical problem used：

A kind of castor, it is characterised in that：With a castor post, the side of castor post is consolidated with paramere in a wheel shaft Even, it is half side in wheel shaft to be connected with the outer paramere of a wheel shaft；Paramere is big with one with the outer paramere of wheel shaft in wheel shaft Diameter cylinders part and a second order cylinder for small diameter cylinders body portion, in wheel shaft on paramere and the outer paramere of wheel shaft Corresponding axial screw and through hole is respectively equipped with, mounting screw makes paramere in wheel shaft through corresponding screw and through hole It is connected with the outer paramere of wheel shaft, paramere forms an outer wall after being connected with the outer paramere of wheel shaft in wheel shaft has annular groove Cylinder, the cylinder is wheel shaft；Castor body is an annular solid, and the inwall of annular solid has a circle annular protrusion, the annular In the above-mentioned annular groove of projection insertion.

The upper surface of paramere cylinder with large diameter body portion is correspondingly provided with several to arc with the side of annular protrusion in wheel shaft Depression, is contained in the arc-shaped recess being oppositely arranged with steel ball；The upper surface of the outer paramere cylinder with large diameter body portion of wheel shaft It is correspondingly provided with the side of annular protrusion several to arc-shaped recess, is contained in steel ball in the arc-shaped recess being oppositely arranged；

Two sides of castor post are symmetrically provided with two wheel shafts and the corresponding castor body installed of wheel shaft, castor post point It is not connected with paramere in two wheel shafts of wheel shaft.

It is of the present utility model to be beneficial in that：

The utility model by being installed with screw and removably connected two parts form wheel shaft, castor body directly in conjunction with Wheel shaft, total dismounts easy to maintenance, low cost.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the utility model structure chart.

Specific embodiment

In order to illustrate more clearly of the technical solution of the utility model, the accompanying drawing to be used needed for description will be made below Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the present utility model, for this area For those of ordinary skill, on the premise of not paying creative work, other implementation can also be obtained according to these accompanying drawings Example.

As shown in figure 1, the utility model is the castor used for case and bag or market small handcart.

The top of castor post 1 and universal joint directly with top body (namely case and bag or small handcart are connected).

The both sides of the lower end side of castor post 1 respectively with the integrally casting shaping of paramere 2 in a wheel shaft.

Paramere 2 is with a cylinder with large diameter body portion 21 and one the two of small diameter cylinders body portion 22 in wheel shaft Rank cylinder, its axle center has through hole 20, and the upper surface of its cylinder with large diameter body portion 21 is evenly distributed in several arc grooves 23。

The outer paramere 3 of wheel shaft is identical with the shape of paramere in wheel shaft 2, is also have a He of cylinder with large diameter body portion 31 One second order cylinder of small diameter cylinders body portion 32, its axle center has through hole 30, its cylinder with large diameter body portion 31 it is upper End face is evenly distributed in several arc grooves 33.

In wheel shaft corresponding axial screw 24 and through hole 34 is respectively equipped with paramere 2 and the outer paramere 3 of wheel shaft.

With a castor body 4, castor body 4 is an annular solid, and the inwall of annular solid 4 has a circle annular protrusion 41, Two side walls of annular protrusion 41 are respectively equipped with arc groove 42 corresponding with the number size of above-mentioned arc groove 23, and and arc The corresponding arc groove 43 of the number size of groove 33.

During installation, steel ball 5 is put into the arc groove 23 of paramere 2 in wheel shaft, sets up castor body 4, be located at steel ball 5 In the space that arc groove 23 and arc groove 42 are surrounded, then steel ball 5 is put in arc groove 43, then set up half outside wheel shaft Lateral body 3, makes steel ball 5 be located in the space that arc groove 43 and arc groove 33 are surrounded, then by screw 6 is through screw 24 and leads to Hole 34 is so as to paramere 2 in the wheel shaft that is connected and the outer paramere 3 of wheel shaft.

Paramere 2 forms an outer wall after being connected with the outer paramere 3 of wheel shaft in wheel shaft has the cylinder of annular groove 7, The cylinder is wheel shaft, so that the annular protrusion 41 of castor body 4 is embedded in above-mentioned annular groove 7.

Then the wheel shaft of the opposite side of installation foot wheel post 1.

So, castor body 4 can be rolled by axle of wheel shaft, realize the function of castor, and steel ball 5 plays support and reduces friction Effect.

Each embodiment is described by the way of progressive in this specification, and what each embodiment was stressed is and other The difference of embodiment, between each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments State bright, professional and technical personnel in the field is realized or use the utility model.Various modifications to these embodiments are right Be will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality In the case of with new spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this These embodiments shown in text, and it is to fit to the most wide scope consistent with principles disclosed herein and features of novelty.
