Abstract

The utility model relates to a baby carriage, whose pedal is stable after being folded, is hard to return and is easy to use. The utility model comprises a frame and wheels at the front and back of the frame, wherein the lower end of the frame is connected with a pedal, and a folder is connected between the pedal and the frame. The folder comprises a connecting frame at the lower end of the frame, wherein the connecting frame is hinged with a connecting rod fixedly mounted with a pedal, the connecting rod is sheathed by a sleeve with a lock, the lock is abut against the side edge of the connecting frame, a spring is provided in the sleeve, whose one end is connected with the wall of the chamber of the sleeve and the another end is abut against to the top of the connecting rod. The baby carriage has the advantages that after being folded, the lock is moved and embedded on a corresponding semicircle concave, the spring moves up the sleeve to lock the lock at the semicircle concave to lock the pedal from automatic release, thereby resolving the problems that the screw cap is easy to lock and is not firm. And the sleeve can be drawn to release the lock from the concave to adjust the pedal to fold or unfold.

Description

A kind of perambulator

Technical field

The utility model is specifically related to a kind of perambulator, mainly be pedal receive the back firm, be difficult for resetting and use with convenient.

Background technology

In the process of driving, advance but self trample arbitrarily, also can promote perambulator by the handle that helps on the perambulator, when adult's go-cart, children's both feet should not be trampled again, should be positioned over pedal, avoid by with the front vehicle wheel that rotates rotation synchronously to the Suo of the pedal on crank Pan or clip to and injured; On the contrary, children trample voluntarily, pack up pedal, avoid unexpected; Country announces that a kind of utility model name is called: the pedal folding device of perambulator, the patent No. is 02257229.5, its structure is: the pipe link side of taking advantage of pedestal of frame for baby cart is penetrated with an axis hole, that L shaped plate sheet vertical end ora terminalis is run through axis hole is symmetrical with this, and with the slotting axis hole that is through at of plug, prominent outer this section plug of axis hole that is through at is equipped with adapter plate in regular turn again, spring, packing ring, and screw togather locking with screw, make this be fixed in the axis hole position while of pipe link side to L shaped plate sheet pivot, this horizontal ends to L shaped plate sheet bottom is fixed in the pipe link both sides towards the external pivot of pipe link, and be that rotating shaft can be swung arbitrarily and formed collapsible and the effect that launches with the plug, the horizontal ends of this bottom respectively runs through several holes, the plate face that supplies the inboard two ends of a pedal to protrude out is striden respectively and is located on the horizontal ends, nut is worn several holes up respectively by the horizontal ends back side and is locked in pedal, pedal is locked on the horizontal ends of L shaped plate sheet to become one.Also there is weak point in above-mentioned structure: fold back employing nut and lock, do not have instrument to be not easy to tighten nut, nut easily gets loose and difficult locking pedal is operated with being not easy to.

The utility model content

The purpose of this utility model is to solve above-mentioned weak point, and a kind of perambulator easy to use and that locking is firm is provided.

The utility model is realized with the following methods: comprise vehicle frame and the wheel that is installed in the vehicle frame front and back, the vehicle frame lower end is connected with a pedal, be connected with folder between its described pedal and the vehicle frame, folder is that the lower end by vehicle frame is provided with link span, link span is hinged with pipe link, be installed with pedal on the pipe link, be with sleeve on the pipe link, latch fitting is arranged on the sleeve, latch fitting peaks on the link span side, spring is arranged in the sleeve, and spring one end is connected on the barrel bore wall, and the other end peaks at the pipe link top and constitutes.

Described link span is the U font by two iron plates, and a screw passes a side iron plate, sleeve, pipe link and opposite side iron plate and joins, and pipe link, sleeve are articulated on the link span.

Have on the described sleeve to be rectangular shape adjusting mouth, its screw passes it and regulates mouth.

There is the semicircle recess on the curved limit of two iron plates, one end on the described link span on the arc limit, the latch fitting of its sleeve both sides is round shape, and latch fitting is embedded in semicircle recess place mutually.

Its end face of two iron plates on the described link span has two straight flanges, and the latch fitting of its sleeve both sides is plane, and latch fitting is corresponding to be embedded on the straight flange position.

The beneficial effects of the utility model are: 1, when folding the back, the latch fitting displacement is embedded on the semicircle recess of relative position, under the effect of its spring, sleeve is upwards moved, make latch fitting locking be fixed in the semicircle recess, it locks pedal position, and pedal the existing picture that gets loose automatically can not occur, solves the easily unstable shortcoming of lock of nut; 2, every pulling sleeve allows latch fitting leave the recess place, and the convenient pedal of regulating folds or launches.
