technical field

The invention relates to a direction wheel, in particular to a front wheel direction wheel for a child carriage.

Background technique

Baby carriages are a major category of children's toys, including children's bicycles, children's strollers, baby walkers, children's tricycles, and children's electric toy cars. There are various types of baby carriages. Generally, children aged 1 to 2 play with baby carriages. , 2 years old and above play with toy cars with wheels, baby carriages will bring certain benefits to children's intellectual development and increase children's brain development.

The existing front wheels for baby carriages are simple in structure and not strong enough, and are prone to deformation or damage due to impact, which affects the normal use of the baby carriage. Moreover, when the baby carriage is moving, if the ground is not smooth enough, the vibration generated is relatively large, which affects the stability of the car body. Stability, which also affects the comfort of children's use, needs to be improved. For this reason, we propose a kind of stroller with front wheel direction wheel.

Further, there are multiple groups of the No. 1 reinforcing rib and the No. 2 reinforcing rib, and the No. 1 reinforcing rib and the No. 2 reinforcing rib are arranged in a staggered manner.

Further, the No. 1 shock absorbing spring is provided on the upper ring of the No. 1 reinforcing rib, and the No. 2 shock absorbing spring is provided on the No. 2 reinforcing rib. The No. 1 shock absorbing spring and the No. 2 shock absorbing spring are respectively connected to the No. 1 The reinforcing rib and the No. 2 reinforcing rib are fixedly connected.

Further, the outer wheel surface is provided with protruding teeth, and the protruding teeth are provided in several groups, and the protruding teeth are arranged clockwise.

Compared with the prior art, the present invention has the following beneficial effects:

1. In the present invention, a No. 1 reinforcing rib is provided between the outer wheel and the inner reinforcing wheel, and a No. 2 reinforcing rib is provided between the inner reinforcing wheel and the center roller, and the No. 1 reinforcing rib and the No. 2 reinforcing rib are staggered. Setting can increase the overall strength of the wheel, prevent the wheel from being deformed when it hits a heavy object, and ensure the integrity of the wheel.

2. The present invention is provided with a No. 1 shock absorbing spring and a No. 2 shock absorbing spring respectively on the No. 1 reinforcing rib and the No. 2 reinforcing rib. When the wheels move, the No. 1 shock absorbing spring and the No. 2 shock absorbing spring can be used to reduce The overall vibration of the wheel can reduce the vibration of the stroller, and the shock absorption effect is good and the stability is high.

3. In the present invention, protruding tooth lines are provided on the surface of the external wheels, and the protruding gears are arranged clockwise, which can increase the gripping force of the external wheels, prevent slipping when going uphill, and have good safety.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

As shown in Figures 1-3, a front wheel directional wheel for a stroller includes an outer wheel 1, an inner reinforcement wheel 2 and a center roller 3, the inner reinforcement wheel 2 is located inside the outer wheel 1, and the center roller 3 Located inside the inner reinforcing wheel 2, there is a No. 1 reinforcing rib 4 between the outer wheel 1 and the inner reinforcing wheel 2. The No. 1 reinforcing rib 4 is arranged in a trapezoidal shape, and the end of the No. 1 reinforcing rib 4 with a larger diameter is connected to the outer The inner wall of the wheel 1 is connected, and the smaller diameter end of the No. 1 reinforcing rib 4 is fixedly connected to the outer wall of the inner reinforcing wheel 2. A No. 2 reinforcing rib 5 is provided between the inner reinforcing wheel 2 and the center roller 3. The No. 2 reinforcing rib 5 Both ends of the reinforcing rib 5 are fixedly connected with the inner wall of the inner reinforcing wheel 2 and the center roller 3 respectively.

Wherein, the No. 1 reinforcing rib 4 and the No. 2 reinforcing rib 5 are provided with multiple groups, and the No. 1 reinforcing rib 4 and the No. 2 reinforcing rib 5 are arranged in a staggered manner.

Wherein, No. 1 shock absorbing spring 7 is provided on the upper ring of the No. 1 reinforcing rib 4, No. 2 shock absorbing spring 8 is provided on the No. 2 reinforcing rib 5, and No. 1 shock absorbing spring 7 and No. 2 shock absorbing spring 8 are fixedly connected with No. 1 reinforcing rib 4 and No. 2 reinforcing rib 5 respectively.
