Abstract

The utility model belongs to the means of transport, particularly a self-locking folding bike, which includes a loading plate, a frame, a handle, and wheels. The self-locking folding bike is characterized in that: the handle and the frame are fixed by a telescopic locking device including a locking bar and a button; the button is provided with a skewed slot; one end of the locking bar is connected in the flume of the button, and can move with the skewed slot; the button is provided with a compressed spring; the handle is provided with a keyhole; the other end of the locking bar can be buttoned into the keyhole of the handle. When the handle is stretched or telescoped, the locking bar can be automatically inserted into the keyhole and locked up. The handle and the frame of the folding bike adopt the telescopic locking device with the reasonable structure; the flume on the button can drive the locking bar to move towards the center as long as the button is pressed; the rocking is detached from the keyhole on the handle, so that the handle can be stretched or telescoped up and down; for locking up the folding bike, the handle is pushed to a certain position, the rocking bar can be automatically inserted into the upper and the lower keyholes on the handle under the action of the compressed spring, thereby achieving the locking purpose.

Description

The self-locking folding car

Technical field

The utility model belongs to the transportation means class, specifically is a kind of self-locking folding car.

Background technology

At present AT STATION, warehouse, supermarket, market, garden etc. are located commonly used to simple and easy carrier car, this rolling cart is generally folding structure, volume after folding is little, be convenient to deposit and use, but the locking mechanism of the collapsible car on the existing market is not very good, some locks not tight when loads, and some is not opened because of being subjected to the structure limitation, thereby influence is used.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, drive the self-locking folding car good with lock function.

The technical solution of the utility model is as follows:

A kind of self-locking folding car, comprise and load plate, vehicle frame, handle, wheel, it is characterized in that: handle and vehicle frame are fixed by the telescopic locking device, the telescopic locking device comprises locking bar, button, and skewed slot is arranged on the button, and locking bar one end is connected in the skewed slot of button, can move with skewed slot, button has stage clip, and keyhole is arranged on the handle, and the locking bar other end can buckle in the keyhole of handle.During telescoping handle, locking bar can insert the keyhole locking of handle automatically.

Loading plate of the present utility model is connected with the vehicle frame axle, can overturn around vehicle frame, at bottom of frame wheel is arranged, and with the connection place of loading plate pair of engaged gears is arranged, during the vehicle frame upset under the engaging gear effect wheel can inwardly rotate.

Handle of the present utility model and vehicle frame have adopted the rational telescopic locking device of structure, as long as pressing button, skewed slot on the button drives locking bar and moves towards the center, locking bar breaks away from the keyhole on the handle, and handle is just capable of expansion and contraction up and down like this, and when locking, handle is pushed over certain position, locking bar can insert the keyhole up and down on the handle automatically under the effect of stage clip, thereby reaches the purpose of locking.

The specific embodiment

As shown in Figure 1, 2, a kind of self-locking folding car, comprise and load plate 7, vehicle frame 5, handle 1, wheel 6, it is characterized in that: handle 1 is fixed by the telescopic locking device with vehicle frame 5, and the telescopic locking device comprises locking bar 2, button 3, on the button 3 skewed slot is arranged, locking bar 2 one ends are connected in the skewed slot of button 3, can move with skewed slot, and button 3 has stage clip 4, on the handle 1 keyhole is arranged, locking bar 2 other ends can buckle in the keyhole of handle 1.During telescoping handle 1, locking bar 2 can insert the keyhole locking of handle 1 automatically, thereby reaches auto-lock function.

Loading plate 7 of the present utility model is connected with 5 of vehicle frames, can in vehicle frame 5 bottoms wheel 6 be arranged around vehicle frame 5 upsets, with the connection place of loading plate 7 pair of engaged gears is arranged, when loading plate 7 upsets, under the gear transmission effect, wheel 6 rotates to vehicle frame 5 centers, thereby finishes the folding of car load.
