Abstract

A multi-wheel foot wheel, especially a multi-wheel truckle comprised in assembly with a truckle bracket and a planet foot wheel. The utility model comprises the assembly of two truckle brackets and more than three planet foot wheels, the distance between the axes of the planet foot wheels and the axes of the moving rotation axis is equal, the truckle bracket is provided with a planet wheel axis hole and a planet wheel axis, and the assembly of the two truckle brackets is a corresponding assembly of a truckle bracket planet wheel axis hole and a truckle bracket planet wheel axis. The two sides of the planet truckle is provided with a symmetric assembly position limiting round groove, the planet truckle position limiting round groove and the truckle bracket are arranged in an open manner with a high position limiting round tenon to relatively cooperate with the low position limiting round tenon clamping arranged in an open manner on the other foot bracket. The beneficial effects of the utility mode are that the device provided with a plurality of foot wheels can turn over obstacles with a certain height, and can move on steps with a certain height. The two side wing plates of the high position limiting round tenon is provided with self cleaning function to scraping off garbage sundries.

Description

Multiple castors

[technical field] Multiple castors relates to a plurality of satellite gear caster wheeles of being with that use on small-sized non-power driven car, hand barrow, shopping cart, the luggage.

[technical background] present castor of the prior art, most single-wheel castors that adopt.The utility model is at the planet castor of installing at least on the single castor more than three.This is a kind of new structure caster wheel, is a kind of technology innovation to castor.

[goal of the invention] is to provide a kind of and is with a plurality of satellite gear caster wheeles, so that still can use the equipment that Multiple castors is housed smoothly under the road conditions that obstacle and small stair are arranged.

[technical scheme] accompanying drawings is as follows: Multiple castors, its keystone configuration are to be made of the planet castor assembling more than three shown in caster wheel support shown in two all figure of Fig. 1 and all figure of Fig. 2; The axle center of planet castor equates to the distance in mobile shaft axle center; Trundle bracket is provided with satellite gear axis hole 6 and planet wheel spindle 3; Two correspondence assemblings that the trundle bracket assembling is a trundle bracket satellite gear axis hole 6 and another trundle bracket planet wheel spindle 3, wheel shaft 3 also can be made the non-integral structure that is separated with trundle bracket.Planet castor both sides are provided with the spacing circular groove 9 of symmetry assembling; The lower bound circle of position tenon of offering on the high spacing round tenon of offering on the spacing circular groove 9 of planet castor symmetry and the trundle bracket 1 and another trundle bracket 4 clamps corresponding matching.Be provided with the circular convex 5 of installing and locating in the satellite gear axis hole 6 on the trundle bracket; The planet wheel spindle 3 of trundle bracket is provided with circumferential registration groove 7.

Planet castor arrangement of the present utility model is a basic number with three, and the symmetric scheme with even number in the planet castor arrangement more than three is good, as four, six, eight, ten or the like; The arrangement of odd number also can be used.

[beneficial effect] is that the equipment that Multiple castors is housed can cross the certain altitude obstacle, can move on the certain altitude step, and high spacing round tenon wing plates on two sides has the self-cleaning function that strikes off the rubbish foreign material.

[description of drawings] Fig. 1-a is that trundle bracket is the A-A section-drawing of Fig. 1-c, Fig. 1-b is that trundle bracket is the B-B section-drawing of Fig. 1-c, Fig. 1-c is the front view of trundle bracket part, Fig. 1-d is that trundle bracket is the E-E section-drawing of Fig. 1-c, the back view of Fig. 1-e trundle bracket part, the block diagram of Fig. 1-f trundle bracket part, wherein be denoted as: the high spacing round tenon of 1-castor, 2-mobile shaft hole, the 3-planet wheel spindle, 4-castor lower bound circle of position tenon, the circular convex of 5-installing and locating, 6-planet wheel spindle mounting hole, 7-planet wheel spindle circumferential registration groove.

Fig. 2-a planet castor part front view, Fig. 2-b planet castor part birds-eye view wherein is denoted as: 8-planet wheel spindle through hole, the spacing circular groove of 9-satellite gear.

[embodiment]

By the technical scheme of this specification sheets, adopt the technical standard of prior art processing castor, adopt the structure that six planet castors are installed, select for use plastic cement, steel and gauge member can produce a kind of product described in the utility model.
