Description

TECHNICAL FIELD

[0001] The utility model relates to baby carriage field, concretely is a rear wheel pipe damping structure on baby carriage. BACKGROUND

[0002] With the continuous improvement of people's living standards and the increase of attention to infant health, baby stroller has become the necessary tool of many family child-rearing, in the process of baby riding stroller, in order to provide a stable, comfortable riding environment for baby, damping function becomes crucial, early baby stroller mostly adopts simple structure design to realize damping, for example, spring is directly installed on the wheel, this way can reduce part of vibration to a certain extent, but for the bump under complex road conditions, the damping effect is not ideal, when encountering more potholes or poor road, the damping capacity of spring is limited, cannot effectively filter all vibrations, so that baby still can feel obvious bump. CONTENT OF THE UTILITY MODEL

[0003] The utility model solves the technical problem in providing a rear wheel pipe damping structure on baby carriage for providing more stable, comfortable riding experience for baby.

[0004] In order to solve the above-mentioned technical problem, the utility model adopts the following scheme: a rear wheel pipe damping structure on baby carriage, including rear wheel, rear wheel joint, rear wheel pipe and support pipe, the rear wheel is symmetrical structure, and the inside of two rear wheels is connected with support rod through rear wheel joint, and rear wheel pipe is installed on each rear wheel joint, and rear wheel pipe is connected with mounting seat through bolt, and lower support piece is connected with upper support piece through support pipe and is connected with upper support piece.

[0005] As preferred, the lower support piece is provided with a limiting sheet, a damping spring is installed between the limiting sheet and the upper support piece, and the damping spring is sleeved and installed on the support pipe.

[0006] As preferred, the surface of the lower support piece is provided with a thread, the lower support piece is connected with the thread groove in the fixed pipe through the thread, the fixed pipe is sleeved with a movable pipe, the inner wall of the movable pipe is provided with a step groove, and the upper support piece is installed on the step groove.

[0007] As preferred, the surface of the support pipe is provided with an adjusting groove, and the adjusting groove is connected with the connecting hole on the upper support piece through a bolt.

[0008] As preferred, the movable pipe slides along the fixed pipe.

[0009] The utility model adopts the above technical scheme to provide a rear wheel pipe damping structure on baby carriage, which can effectively dampen in different flat road sections, compared with the prior art, has the following advantages:

[0010] 1. Effectively reduces vibrations transmitted from road bumps to the baby's riding area. Whether on brick roads in the city, dirt roads in the countryside, or uneven floors in shopping malls, the rear wheel tube shock absorption structure of the stroller can filter out vibrations caused by uneven ground to a great extent during the ride, making the baby feel as comfortable as if they were in a relatively stable environment, just like in a quiet room. This avoids discomfort caused by excessive bumps and ensures the baby's physical comfort while riding.

[0011] 2. Significantly reduces the impact force caused by bumps, avoiding damage to the baby's head, neck and spine, and providing effective protection for the baby's physical development. Attached Figure Description
