Abstract

A steering mechanism for four-wheel baby carrier is composed of a frame, a front axle sleeve fixed to front end of frame, a connecting plate fixed to handle column, a bent part under said handle column, and a front axle fixed to lower surface of said sleeve. The utility model discloses simple structure turns to in a flexible way light, and any wheel is when crossing the barrier such as fragment of brick in especially the front wheel, and the automobile body can not produce the slope, therefore whole car balance performance is good.

Description

Four-wheel perambulator steering hardware

The utility model relates to the perambulator technical field, more particularly relates to a kind of steering hardware of four-wheel perambulator.

Existing children mostly are two by bike, tricycle structure, and its steering hardware is all continued to use into the steering hardware of person bicycle, complex structure, poor safety performance.And the four-wheel perambulator mostly is power with the storage battery, and its steering hardware is steering wheel type, has baroque defective equally, and the balance quality that travels is poor.The patent No. is 95233670 " power of four-wheel perambulator and steering hardware ", still fails to address the above problem.

The purpose of this utility model is exactly that a kind of flexible, simple in structure, as can to improve the car load balance quality greatly four-wheel perambulator steering hardware that turns to will be provided.

The utility model comprises the handle-bar stem of captiveing joint with handlebar in handlebar and upper end, the lower end of handle-bar stem is equipped with the front wheel spindle that front-wheel is equipped with at two ends, its constructional feature is that the front end at vehicle frame is fixed with the bearing pin sleeve pipe, the rear side of handle-bar stem is fixed with two connecting panels up and down, and two connecting panels are hinged by the bearing pin and the bearing pin sleeve pipe that are inserted in the bearing pin sleeve pipe.The handle-bar stem bottom has bending, is movably installed with sleeve pipe on it, and the front wheel spindle vertical fixing is installed in below the sleeve pipe.

The utility model also is equipped with the limiting steering device on bearing pin sleeve pipe and connecting panel.

Compare with the steering hardware of existing four-wheel perambulator, the utility model is simple in structure, and productive costs is low, turn to lightly flexibly, particularly any one take turns when the obstacle of crossing such as fragment of brick in the front-wheel, vehicle body can not produce inclination, thereby the car load balance quality is good, the steady safety of travelling.

Below in conjunction with drawings and Examples, the utility model will be further described.

Fig. 1 is a front view of the present utility model, shows its integral structure;

Fig. 2 is a birds-eye view of the present utility model;

Fig. 3 is for using the front view of four-wheel perambulator of the present utility model;

Fig. 4 is the birds-eye view of Fig. 3.

In the embodiment that accompanying drawing provides, the U-shaped structure that handlebar of the present utility model (1) makes progress for opening, and low skewed in high back before being.The following captive joint of handlebar (1) handle-bar stem (2), and handle-bar stem (2) bottom has a bending, and its front portion is on the part of level and is set with a sleeve pipe (10), and handle-bar stem (2) can rotate in sleeve pipe (10) flexibly.Front wheel spindle (11) vertical fixing is installed in below the sleeve pipe (10), and a front-wheel (9) respectively is equipped with at its two ends.Be fixed with one at the front end of vehicle frame (6) and be skewed bearing pin sleeve pipe (5), rear side at handle-bar stem (2) is fixed with two connecting panels (3) up and down, the two ends up and down of the corresponding bearing pin sleeve pipes of two connecting panels (3) (5), hinged by the bearing pin (4) that is inserted in the bearing pin sleeve pipe (5) with the bearing pin sleeve pipe.Be fixed with limiting steering plate (7) on bearing pin sleeve pipe (5), be fixed with limited post (8) on lower connecting plate (3), form the limiting steering device jointly, the amplitude that turns to restriction is in order to avoid overturn.

Claims

1, a kind of four-wheel perambulator steering hardware, comprise handlebar (1), the handle-bar stem of captiveing joint with handlebar (1) in the upper end (2), and the front wheel spindle (11) of front-wheel (9) is equipped with at the two ends that are installed in handle-bar stem (2) lower end, it is characterized in that: the front end of vehicle frame (6) is fixed with bearing pin sleeve pipe (5), the rear side of handle-bar stem (2) is fixed with two connecting panels (3) up and down, and two connecting panels (3) are hinged with bearing pin sleeve pipe (5) by the bearing pin (4) that is inserted in the bearing pin sleeve pipe (5); Handle-bar stem (2) bottom has bending, is movably installed with sleeve pipe (10) on it, and front wheel spindle (11) vertical fixing is installed in below the sleeve pipe (10).

2, four-wheel perambulator steering hardware according to claim 1 is characterized in that on bearing pin sleeve pipe (5) and connecting panel (3) the limiting steering device being housed.

3, four-wheel perambulator steering hardware according to claim 1 is characterized in that the U-shaped structure that handlebar (1) makes progress for opening.
