Abstract
The invention discloses a front wheel orientation device of a pushchair, comprising a front wheel joint. One end of the front wheel joint is connected with a frame, and the other end of the front wheel joint is provided with a front wheel seat which is movably connected with the front wheel joint and glidingly connected with an orientation block. The front wheel orientation device of the pushchair not only has a simple structure and convenience in operation, but also is safe and reliable and can realize an orientation effect only by lightly poking the orientation block.
Description
Technical field
The present invention relates to a kind of orienting device of doll carriage, particularly a kind of front-wheel orienting device of doll carriage.
Background technology
At present, all be provided with orienting device on the front-wheel of doll carriage, improve the safety of doll carriage, reliability, with and alerting ability, but existing orienting device all is to adopt latch, the anchor fitting of jack or the anchor fitting of some lock pins mostly, this ancient anchor fitting, use to people and brought very big inconvenience, and safety is bad, dumb.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of safe and reliable, the front-wheel orienting device of directed flexible doll carriage.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of front-wheel orienting device of doll carriage, comprise the front-wheel joint that an end and vehicle frame join, wheel seat before the other end of front-wheel joint is provided with one, front-wheel joint and preceding wheel seat flexibly connect, and slidely connect a directed piece on the preceding wheel seat.
As a further improvement on the present invention, preceding wheel seat is provided with two first directional holes, directed piece is provided with second directional hole that first directional hole on a plurality of and described preceding wheel seat matches, be provided with a spring and steel ball in each described first directional hole, also be provided with a fixture block on the preceding wheel seat, the draw-in groove on fixture block and the directed piece matches.
As a further improvement on the present invention, offer on the directed piece one with preceding wheel seat on the draw-in groove that matches of fixture block, the anchor fitting of fixture block and draw-in groove formation close fit.
As a further improvement on the present invention, between front-wheel joint, preceding wheel seat and the directed piece plane contact is arranged, directed piece is done at front-wheel joint, preceding wheel seat and is slided up and down motion.
The invention has the beneficial effects as follows: not only simple in structure, be convenient to operation, and safe and reliable, as long as gently stir directed piece, just orientable effect.
