Abstract
The utility model relates to a removable structure for rear wheels of a baby carriage. The removable structure comprises a lambdoidal rear wheel bracket and the rear wheels arranged at fork ends on the two sides of the rear wheel bracket. Each rear wheel comprises a tire and a hub, wherein a mounting hole is formed in the hub; a locking ring is fixedly arranged in the mounting hole; and a bearing is arranged in the inner center of a ring of the locking ring. Each fork end of the rear wheel bracket is provided with a wheel shaft connected with the bearing. A plurality of locking tooth spaces are formed on the inner wall of each locking ring. Each fork end of the rear wheel bracket is provided with a locking pin which can be connected with the locking tooth spaces in a matching way. The utility model has the advantages that the removable structure is simple and convenient to use; one ends of the locking pins can be clamped into the locking tooth spaces through control handles to limit the rolling of the rear wheels, and the rear wheels can be detached from the fork ends of the rear wheel bracket by disconnecting locking clamps from stepped grooves on the wheel shafts.
Description
Technical field
The utility model relates to a kind of perambulator, the dismantled and assembled structure of particularly a kind of perambulator trailing wheel.
Background technology
Most perambulator of the prior art or carriage for children all can fold, not switch between the folded state, and this based article allows easily to carry and deposit this goods behind folded state, and therefore this moment, goods were in compact condition.At present, the trailing wheel of perambulator all is connected with front-wheel support or rear wheel support and on-dismountable.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, provides a kind of perambulator trailing wheel dismantled and assembled structure.
For achieving the above object; The utility model adopts following technical scheme: the dismantled and assembled structure of perambulator trailing wheel, comprise " people " font rear wheel support and the trailing wheel that is installed in rear wheel support both sides fork, and said trailing wheel comprises tire, wheel hub; Be provided with mounting hole in the wheel hub; Be fixed with the locking circle in this mounting hole, the center is provided with bearing in the circle of locking circle, and the fork of rear wheel support is respectively equipped with and bearing bonded assembly wheel shaft; The inwall of said locking circle is provided with some locking teeth groove, the fork of rear wheel support be provided with can with the stop pin that is connected of locking teeth groove.
For a kind of optimization of the utility model, the axle head of said wheel shaft is provided with step groove, and the axial bottom of mounting hole is provided with and step groove bonded assembly locking card in the wheel hub.
A kind of optimization for the utility model; The fork outside of rear wheel support is provided with control handle; The fork of rear wheel support is provided with the stop pin pilot hole near wheel shaft one side, and said stop pin is positioned at the stop pin pilot hole, and in the cavity of said stop pin one end between locking teeth groove and bearing; Its other end passes the stop pin pilot hole and is connected with the control handle end, and the fork of said control handle end one side and rear wheel support is hinged.
The utility model is compared with background technology, has simple in structure, easy to use; Can stop pin one end be snapped in the locking teeth groove through control handle; Thereby limit the rolling of trailing wheel, and top bar being connected between the groove with wheel shaft, the fork of trailing wheel dismounting disengaging rear wheel support through breaking off the locking card.
