Abstract

A seat back inclination stepless regulating mechanism for a baby carriage is characterized in that the mechanism comprises a seat back [4] which is movably connected with a frame, an assist strap which is positioned on the frame. The assist strap encloses the seat back [4] from the rear part of the seat back [4]; the assist strap comprises a first assist strap [5] and a second assist strap [7], both of which are clamped by a clamp. After the first assist strap and the second assist strap are clamped by the clamp, the distances between the first assist strap and the frame as well as between the second assist strap and the frame can be regulated when different positions of the assist straps are clamped, thus the angle of the seat back can be adjusted with convenience and simple operation.

Description

The backrest angle stepless regulating mechanism of perambulator

The utility model relates to the backrest angle regulating mechanism of a kind of perambulator, particularly perambulator.

In the prior art, the backrest of perambulator need according to circumstances carry out angular adjustment, the bottom of back support bar is hinged on the vehicle frame, the tooth bar of an arc is fixed on the vehicle frame, the securing rod of lockout mechanism is inserted in the tooth of diverse location and makes that the angle of backrest is regulated, but this adjusting is the adjusting that level is arranged, and can not make backrest equal lockable at an arbitrary position.

The purpose of this utility model is to provide a kind of backrest angle stepless regulating mechanism of perambulator simple in structure, easy to adjust.

The technical solution of the utility model is: a kind of backrest angle stepless regulating mechanism of perambulator, it comprises the backrest that flexibly connects with vehicle frame, is arranged at the suspender belt on the vehicle frame, described suspender belt catches backrest from the rear portion of described backrest, described suspender belt comprises first suspender belt and second suspender belt, and described first suspender belt and second suspender belt are sandwiched on the clip.

The utility model compared with prior art has following advantage:

After clamping first suspender belt and second suspender belt by clip since when being clipped in the diverse location of suspender belt the distance between scalable first suspender belt and the vehicle frame and, the distance between second suspender belt and the vehicle frame, so backrest can adjusting angle, and is easy to adjust, simple.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is the spatial structure view of perambulator; Accompanying drawing 2 is the spatial structure view of clip of the present utility model;

Accompanying drawing 3 is the main cutaway view of clip of the present utility model; Wherein:

[1], wheel; [2], foreleg; [3], back leg; [4], backrest; [5], first suspender belt; [6], pushing hands bar; [7], second suspender belt; [8], first clamp; [9], draw ring; [10], rotating shaft; [11], second clamp; [12], torsion spring; [13], the first clamp hangnail; [14], the second clamp hangnail;

Embodiment: referring to accompanying drawing 1 to accompanying drawing 3, a kind of backrest angle stepless regulating mechanism of perambulator, it comprises the backrest [4] that flexibly connects with vehicle frame, is arranged at the suspender belt on the vehicle frame, described suspender belt catches backrest [4] from the rear portion of described backrest [4], described suspender belt comprises first suspender belt [5] and second suspender belt [7], and described first suspender belt [5] and second suspender belt [7] are sandwiched on the clip.

In the accompanying drawing 2, described clip comprises first clamp [8], second clamp [11], described first clamp [8] and second clamp [11] are by rotating shaft [10] pivotal joint, first suspender belt [5] and second suspender belt [7] to clamping, can be regulated the length of the suspender belt that catches backrest [4] by described first clamp [8] and second clamp [11].

Be with torsion spring [12] in the described rotating shaft [10], one end of this torsion spring [12] is connected on first clamp [8], the other end of this torsion spring [12] is connected on second clamp [11], and this torsion spring [12] makes clamp of winning [8] and second clamp [11] continue to be in clamped condition to suspender belt.

Referring to accompanying drawing 1, the upper end of described first suspender belt [5] and second suspender belt [7] is fixedly connected on the pushing hands bar [6] in the vehicle frame.

The surface of clamping first suspender belt [5] and second suspender belt [7] of described first clamp [8] and second clamp [11] is provided with hangnail.Hangnail comprises the hangnail on the first clamp hangnail [13], [14] two parts of the second clamp hangnail.
