Abstract

The utility model discloses daily supplies, and aims to provide a spherical castor. The spherical castor is characterized in that the spherical castor comprises a base, a shell body fixed to the base and a spherical idler wheel. The spherical idler wheel is movably embedded in the shell body, part of the spherical idler wheel is exposed out of the shell body and makes contact with the ground, a fixing support is connected to the side face of the base, and the side face of the base is connected with the fixing support through bolts. The fixing support comprises support frames and a fixing base, support frames are arranged at the two opposite sides of the fixing base, the support frames are of triangular prism structures, the fixing support is fixed to the side face of the base, the fixing support is connected to the side face of the base to fix a box body due to the fact that the spherical body can not be fixed easily and slides easily, and the position of the fixing support can be adjusted. The base and the fixing support are fixedly connected through the bolts, and operation is simple and convenient; support faces are of the triangular prism structures, by the adoption of the principle that the triangular prism is high in stability, the triangular prism structures are more stable in fixing and not prone to damage. The spherical castor is suitable for the fixing.

Description

The ball castor

Technical field

The utility model relates to a kind of articles for daily use, and more particularly, it relates to a kind of castor of case and bag.

Background technology

The castor of case and bag is mounted in case and bag bottoms, for supporting case and bag and providing power-assisted for the movement of case and bag.

At present, on market, many need is all equipped with the ball castor below mobile article, be called universal wheel, it should have the ability of certain load capacity, play again conveniently moving, its structure of the ball castor used is made up of base, the housing that is fixed on base, spherical roller, central shaft, housing is fixed on base with riveting axle, can do the planar circumferential rotation of doing 360 degree around riveting axle, spherical roller is positioned over central shaft two ends in housing by a central shaft passing along its diametric(al) and is fixed on housing, and spherical roller can rotate around central shaft.Although this ball castor can move arbitrarily, its Castor structure complexity, and not for structure fixing, that support, while placing on the ground, easily, because external force or inertia are subjected to displacement, does not have fixing ability.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of ball castor, simple in structure, has supporting construction can be fixed casing.

For achieving the above object, the utility model provides following technical scheme: a kind of ball castor, comprise base, be fixed on housing, the spherical roller of base, described spherical roller is movably embedded in housing and partly and is placed on outside housing and contacts with ground, described base side is connected with fixed mount, and base side and fixed mount are bolted; Described fixed mount comprises bracing frame and firm banking, and relative self both sides of firm banking are provided with bracing frame, the triangular prism structure that bracing frame is sheet, and screwed hole is greater than the distance of screwed hole to spherical roller bottom to the distance of firm banking.

By adopting technique scheme, described fixed mount is fixed on base, because spheroid is difficult for fixing, easily slides, and base is rotatably connected fixed mount surely, thereby is fixed casing, can adjust the position of fixed mount simultaneously; Both are fixed connection by bolt, simple to operation; Described supporting surface is set to triangular prism structure, utilizes the high principle of stability of triangular prism, more stable while making it fixing, not fragile.

The utility model is further set to: described bolt top is connected with rotary switch, and rotary switch and bolt are connected to welding.

By adopting technique scheme, described connector is bolt, is fixed its degree of tightness situation by screw thread rotation, is welded with rotary switch on screw thread, makes its Stability Analysis of Structures firm, controls more easily its degree of tightness situation by rotary switch.

The utility model is further set to: described inner walls is inlaid with some free balls, and free ball and spherical roller are conflicted mutually.

By adopting technique scheme, between described housing and castor, be provided with free ball, free ball inlay with housing in and mutually conflict with circular castor, the principle of utilizing spheroid easily to roll, more convenient when its spherical roller is done relative motion.

The utility model is further set to: described housing and fixed mount are all coated with nickel metal material.

By adopting technique scheme, described housing and fixed mount are all coated with nickel metal material, make its material not fragile, avoid it to damage because of oxidation, more environmental protection.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the utility model ball castor embodiment is described further.

A kind of ball castor, comprise base 7, be fixed on housing 1, the spherical roller 3 of base 7, described spherical roller 3 is movably embedded in housing 1 and partly and is placed on outside housing 1 and contacts with ground, and described base 7 sides are connected with fixed mount 2, and base 7 sides are connected by bolt 6 with fixed mount 2; Described fixed mount 2 comprises bracing frame 21 and firm banking 22, the relative both sides of firm banking 22 are provided with bracing frame 21, the triangular prism structure that bracing frame 21 is sheet, screwed hole is greater than the distance of screwed hole to spherical roller 3 bottoms to the distance of firm banking 22, and described fixed mount 2 is fixed on base 7 sides, because spheroid is difficult for fixing, easily slide, base 7 sides are connected with fixed mount 2, thereby are fixed casing, can adjust the position of fixed mount 2 simultaneously; Both are fixed connection by bolt 6, simple to operation; Described supporting surface is set to triangular prism structure, utilizes the high principle of stability of triangular prism, more stable while making it fixing, not fragile.

Described bolt 6 tops are connected with rotary switch 4, rotary switch 4 is connected to welding with bolt 6, described connector is bolt 6, be fixed its degree of tightness situation by screw thread rotation, on screw thread, be welded with rotary switch 4, make its Stability Analysis of Structures firm, control more easily its degree of tightness situation by rotary switch 4.

Described housing 1 inwall is inlaid with some free balls 5, free ball 5 is conflicted mutually with spherical roller 3, between described housing 1 and castor, be provided with free ball 5, free ball 5 inlay with housing 1 in and mutually conflict with circular castor, the principle of utilizing spheroid easily to roll, more convenient when its spherical roller 3 is done relative motion.

Described housing 1 and fixed mount 2 are all coated with nickel metal material, make its material not fragile, avoid it to damage because of oxidation, more environmental protection.
