Abstract
The utility model oblique side type universal caster, which is composed of a rotary vertical shaft, a rotary semi-wheel, a roll semi-wheel, a central shaft and roller balls, wherein, a rotary vertical shaft hole and screw pin holes are arranged on the top of the rotary semi-wheel; roller balls are arranged on the bottom of the rotary vertical shaft hole; the rotary vertical shaft and the rotary semi-wheel are rotationally connected and positioned by screw pins. The rotary semi-wheel and the roll semi-wheel are rotationally connected through the central shaft, a spring block ring and a plurality of small roller balls; an outer decorative cover is arranged on the outer side of the roll semi-wheel. The utility model has the advantages of simple structure, convenient assembly, material saving, low cost, etc.
Description
The utility model angle-side type universal caster wheel, it belongs to a kind of free revolving action caster wheel that has.
Application number provides a kind of " high capacity universal caster wheel " for 93206369.1 utility model, its rotation is partly taken turns and half wheel that rolls of landing all is semisphere, between vertical rotation shaft and rotation half wheel, rotation is partly taken turns and land that to roll between half wheel all be to be connected by elastic spring and with the back-up ring annular groove of its coupling.This Castor structure is complicated, the cost height, and materials are many.
For overcoming the shortcoming that above-mentioned prior art exists, the utility model provide a kind of simple in structure, materials are saved, spherical shapes is changed into the universal caster wheel of angle-side type.
The purpose of this utility model is achieved in that by vertical rotation shaft, rotation half wheel, half wheel rolls, the angle-side type universal caster wheel that center shaft and ball are formed, the bottom of vertical rotation shaft that is characterised in that of the present utility model has annular cotter slot, the threaded pin hole that the top of rotation half wheel is provided with vertical vertical rotation shaft hole and is communicated with its level, bottom, vertical rotation shaft hole installing ball, vertical rotation shaft inserts in the vertical rotation shaft hole, locate by threaded pin, and be with rotation half wheel and be rotationally connected, the cross section, inboard boss outer of rotation half wheel is an arc, the surperficial radian coupling of its radian and little ball.Half wheel that rolls is made up of wheel bone and injection moulding wheel rim, and the border, bottom of wheel bone inner circular groove is a ball grooves, places the little ball of a circle along groove, this groove with rotate the complete ball grooves of the relative formation of the cambered surface of partly taking turns inboard boss outer.Rotation half wheel is connected by center shaft with half wheel that rolls, and center shaft one end is flush fit with the central axis hole of rotation half wheel and is connected, and the other end has the back-up ring annular groove, places trip ring in the groove, and the exterior trim cover is equipped with in the half wheel outside of rolling.
Description of drawings is as follows:
Fig. 1 is the decomposing schematic representation of angle-side type universal caster wheel
Fig. 2 is the lateral plan of angle-side type universal caster wheel
Fig. 3 is the medial elevational view of rotation half wheel
Below in conjunction with accompanying drawing the utility model is further described: referring to Fig. 1～Fig. 3, the angle-side type universal caster wheel is made up of vertical rotation shaft (1), rotation half wheel (2), roll half wheel (3), center shaft (4) and ball (6), wherein the bottom of vertical rotation shaft (1) has annular cotter slot (5), the external diameter coupling of groove width and threaded pin (9); Rotation half wheel (2) top is provided with vertical vertical rotation shaft hole (7) and the threaded pin hole (8) that is communicated with its level, ball (6) places the bottom of vertical rotation shaft hole (7), vertical rotation shaft (1) is inserted in the vertical rotation shaft hole (7), locate by threaded pin (9), and be rotationally connected with rotation half wheel (2), the cross section, inboard boss outer of rotation half wheel (7) is an arc, the surperficial radian coupling of its radian and little ball (12).Half wheel (3) that rolls is made up of wheel bone (14) and injection moulding wheel rim (15), the border, bottom of wheel bone (14) inner circular groove is ball grooves (16), it and the complete ball grooves of the relative formation of cambered surface that rotates half wheel (2) inboard boss outer, place a circle little ball (12) in the groove, rotation half wheel (2) and roll and lean on little ball to do between half wheel (3) to relatively rotate.Rotation half wheel (2) is connected by center shaft (4) with half wheel (3) that rolls, center shaft (4) one ends are flush fit with the central axis hole (10) of rotation half wheel (2) and are connected, the other end has back-up ring annular groove (11), place trip ring (17) in the groove, the central axis hole (13) that center shaft (4) passes half wheel (3) that rolls is rotationally connected with center shaft (4) by trip ring (17) half wheel (3) that will roll, and exterior trim cover (18) is equipped with in half outside of taking turns (3) of rolling.During use, whole castor can be done around vertical rotation shaft (1) and horizontally rotate, and half wheel (3) that rolls can rotate around center shaft (4).
The utility model compared with prior art has the following advantages: simple in structure, easy to assembly, materials are economized, cost is low.
