Compared with the prior art, the utility model discloses owing to need not set up the draw-in groove at the tip of rear wheel axle sleeve, solved the difficult problem of installation of rear wheel axle sleeve tip deformation, utilize the setting element as handle support behind the screw simultaneously, kill two birds with one stone.
Description
Technical Field
The utility model relates to a baby carriage.
Background
The shaft sleeve and the rear wheel sleeve of the baby carriage sold in the market at present are positioned in an anti-rotation mode through the clamping groove at the end part of the rear wheel sleeve and the clamping protrusion of the shaft sleeve. The structure has the defects that after the end part of the rear wheel sleeve is provided with the clamping groove, the notch is easy to deform, so that the shaft sleeve is difficult to mount, and sometimes the shaft sleeve needs to be mounted after being corrected, so that the mounting efficiency is influenced, and meanwhile, the product is not attractive. In addition, the sleeve part of the handle bracket is also sleeved on the rear wheel sleeve, so that the clamping height of the shaft sleeve is small, and the rear wheel sleeve is easy to loosen after deformation. Therefore, the technical problem to be solved at present is to design a baby carrier which utilizes the positioning holes and the positioning screws to fix the shaft sleeve and the rear wheel sleeve.
Disclosure of Invention
The utility model aims to solve the technical problem that a bassinet of fixed axle sleeve of locating hole and set screw and rear wheel sleeve pipe is provided.
The technical proposal of the utility model for solving the technical problem is that:
a baby carriage comprises a rear wheel sleeve of a frame, a shaft sleeve and a handle support, wherein a shaft sleeve positioning screw through hole is formed in a pipe body at the outer end part of the rear wheel sleeve, an internal thread blind hole which corresponds to and is matched with the shaft sleeve positioning screw through hole in the rear wheel sleeve is formed in a sleeve body at the outer end part of the shaft sleeve, the shaft sleeve and the rear wheel sleeve are locked through screws, a positioning groove which is matched with a screw head of the screw is formed in the inner wall of a sleeve part of the handle support, and the handle support is connected with the rear wheel sleeve in an anti-rotation positioning mode through the screw head of the screw.
As a preferred scheme of the utility model, still include the shaft, be fixed with the wheel at the outer tip of shaft, the dress is worn in the axle sleeve to the shaft hub by the shaft, has the retaining ring groove in the tip of shaft, has the shaft locking device mounting hole in the tip of rear wheel sleeve pipe and axle sleeve, and the shaft passes through shaft locking device and can dismantle with rear wheel sleeve pipe and axle sleeve and be connected.
As an optimized scheme of the utility model, shaft locking device constitute by shaft latch segment, compression spring and end cap, there is the vertical slot hole that width and shaft matched at shaft latch segment middle part, the shaft wears to adorn in the vertical slot hole of shaft latch segment, the rear wheel cover outside the upper end of shaft latch segment stretches out, compression spring passes through the end cap shutoff to the shaft locking device mounting hole of axle sleeve in, compression spring is between the lower extreme of end cap and shaft latch segment, normal condition shaft latch segment card is in the location annular of shaft, when pressing down the shaft latch segment, the shaft latch segment breaks away from the location annular of shaft, the shaft can be taken out, otherwise, press the shaft latch segment, insert the shaft in the shaft cover, loosen the shaft latch segment, in the location annular of shaft is gone into to the shaft latch segment card under compression spring's effect.
Compared with the prior art, the utility model discloses owing to need not set up the draw-in groove at the tip of rear wheel axle sleeve, solved the difficult problem of installing of rear wheel axle sleeve tip deformation, utilize the setting element as handle support behind the screw simultaneously, kill two birds with one stone, do not have the pine between axle sleeve and the rear wheel sleeve and take off the phenomenon.
