Abstract
The utility model relates to a plastic wheel braking device of a wheel chair, which comprises a hollow wheel shaft and flange discs arranged at both ends of the hollow wheel shaft, wherein the flange discs are fixedly provided with an outer expanding type braking mechanism; a plastic wheel arranged at the outer side of the flange discs is connected with the wheel shaft through a fast disassembling and assembling rod; the surface of a braking iron ring of the plastic wheel is provided with convex blocks/pieces/tables which are embedded at the inner side of a wheel hub of the plastic wheel, and the convex blocks/pieces/tables are injection molded with the plastic wheel in an integral mode; the braking mechanism comprises braking discs which are fastened with the flange discs; the braking discs are provided with two half annular braking rings capable of opening and closing, and the braking rings are provided with braking sheets; the braking iron ring is connected with movable sleeves of the braking discs. When a rotating arm is pulled, outer expansion or closure of the braking sheets can be pushed through the long and the short edges of a flat head pin. Because the utility model is an inner braking wheel hub type, the braking iron ring is firmly matched with the wheel hub without loosening, and the braking is quick and powerful; the utility model has the advantages of reasonable structure, easy manufacture and convenient and fast disassembly and assembly.
Description
Technical field
This utility model relates to a kind of plastic roller brake gear of wheelchair, also applicable to stroller that left and right wheels is arranged or perambulator.
Background technology
Existing wheelchair kind is more, and the brake gear structure is different.As China Patent No. 992097584 disclosed a kind of Brake of wheel-chair devices, be that a control stick is set in a body, one brake cable can monolateral effect control stick the stock end do the lever motion, make the brake fork of a quarter butt end do deflection, the brake member two ends connect respectively and are located on control stick and the fork, brake member can radially be drawn towards the wheel hub center move, reach whereby and promote braking effect and labour-saving purpose.It is the hub-type of stopping outward, and its structure is complicated, and dustproof effect is undesirable.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, the brake stopper is strong rapidly, in the stop plastic roller brake gear of wheelchair of hub-type, to overcome weak point of the prior art.
Press the plastic roller brake gear of a kind of wheelchair of this purpose design, the ring flange that comprises hollow axle and two ends thereof, be fixed with outer expanding braking mechanism on the ring flange, the plastic roller in the outside links to each other with wheel shaft by fast dismounting bar, its architectural feature is that brake iron hoop surface is provided with projection/sheet/platform, embed plastic roller wheel hub inboard, with the plastic roller integrated injection molding.
Described brake iron hoop is the cup-shaped of bottom opening, and the cup end outwards stamps out a plurality of boss, and rim of a cup extends outward the lug of a plurality of inclinations, and described boss, lug embed among the wheel hub.
Described braking mechanism comprises and the fastening brake disc of ring flange, but brake disc is provided with two semiorbicular brake rings of folding, and brake ring is provided with brake block; The brake iron hoop is connected with the brake disc kink.The ring flange edge extends a support arm, and support arm is provided with the compensating roller bolt of brake steel cable; Two semiorbicular brake ring one end riveteds, near the homalocephalus pin, the other end of homalocephalus pin is fixed with the brake pivoted arm to the other end under the effect of C shape turn; During the pulling pivoted arm, bloated or closed outward by the length limit promotion brake block of homalocephalus pin.
The central authorities of described ring flange are penetrated with sleeve pin and sleeve; Fast dismounting bar successively runs through wheel hub, sleeve pin, the positioning ball of rod front end with wheel alignment in the wheel shaft both sides.
This utility model hub-type of stopping in being, the brake iron hoop cooperates with wheel hub firmly, can not become flexible, and the stopper that brakes is strong rapidly, and it is simple and reasonable, handling ease, dismounting is fast.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
Referring to Fig. 1--Fig. 3, the plastic roller brake gear of this wheelchair comprises the ring flange 3 at hollow axle 2 and two ends thereof being fixed with outer expanding braking mechanism on the ring flange that the plastic roller 13 in the outside links to each other with wheel shaft by fast dismounting bar 14.Braking mechanism comprises and the brake disc 5 of ring flange 3 by bolted, but brake disc is provided with two semiorbicular brake rings 8 of folding, and brake ring is fixed on the brake disc 5 by homalocephalus pin 11 and rivet 10, and brake ring 8 is provided with brake block 9; Brake iron hoop 6 is connected with brake disc 5 kinks.Brake iron hoop 6 is the cup-shaped of bottom opening, and the cup end outwards stamps out a plurality of boss 6.2, and rim of a cup extends outward the lug 6.1 of a plurality of inclinations, and described boss, lug embed wheel hub 12 inboards, with the plastic roller integrated injection molding.Extend a support arm 3.1 on ring flange 3 edges, support arm is provided with the compensating roller bolt 3.2 of brake steel cable; Two semiorbicular brake ring 8 one ends are by rivet 10 riveteds, and near homalocephalus pin 11, the other end of homalocephalus pin is fixed with brake pivoted arm 1 to the other end under the effect of C shape turn 15; During the pulling pivoted arm, outer bloated or closed by the length limit promotion brake block 9 of homalocephalus pin, realize brake.
The central authorities of ring flange 3 are penetrated with sleeve pin 7 and sleeve 4; Fast dismounting bar 14 successively runs through wheel hub 12, sleeve pin 7, and the positioning ball of rod front end is positioned at wheel shaft 2 both sides with plastic roller 13.The wheel hub two ends are provided with bearing 16.
This brake gear adopts steel or aluminum alloy materials to make.
