Embodiment 1

[0025] See figure 1 , figure 2 The stroller wheel shown includes a hub 2 and a tire 1 fixedly sleeved on the outer circumference of the hub 2.

[0026] See figure 2 , image 3 As shown, the tire 1 is a non-inflatable tire. The tire 1 is provided with a hollow groove 11 with a notch 13 along the circumferential direction of the tire 1. The notch 13 is located on the inner periphery of the tire 1. The inner peripheral part is divided by the notch 13 so that the inner peripheral part of the tire 1 is located on both sides of the notch 13 to form annular support parts 14 respectively. Through the annular support parts 14, the tire 1 can be fixedly sleeved to the hub 2 On the outer periphery of the body. Due to the hollow groove cavity 11, the elasticity of the tire 1 can be effectively improved, so that the overall wheel has a good shock absorption effect.

[0027] In this embodiment, see figure 2 , 3 As shown, the annular support portion 14 on the tire 1 is also provided with an a...

Embodiment 2

[0034] See Figure 4 , Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the annular reinforcement 3 is fixedly embedded in the circumferential groove wall of the hollow groove cavity 11 by integral molding. When the tire 1 is produced and processed, the annular reinforcement 3 is placed in the injection molding mold of the tire 1, and then the tire 1 is molded by pouring; during the molding process, the circumferential groove wall in the hollow groove cavity 11 located radially outside the tire 1 is convex inward A covering portion 16 is formed to wrap the annular reinforcement 3 so that the annular reinforcement 3 is fixedly embedded in the circumferential groove wall of the hollow groove cavity 11 to form an integral body with the tire 1. This method is more convenient in actual production and processing. The annular reinforcement 3 always forms a fixed support for the tire 1 in the radial direction without detachment.

Abstract

The invention discloses a baby carriage wheel. The baby carriage wheel comprises a wheel hub and a tire which is fixedly arranged on the outer side circumferential portion of the wheel hub in a sleeving manner, wherein the tire is provided with hollow groove cavities with notches along the circumferential direction of the tire, the notches are located at the inner side circumferential portion of the tire, at least one elastic annular reinforcer which is located in each hollow groove cavity is further fixedly arranged on the tire, and the outer side circumferential portions of the annular reinforcers are fixedly abutted against circumferential groove walls, which are located outside the tire in the radial direction, of the hollow groove cavities. When the tire is compressed, the annular reinforcers can supply a support to the circumferential groove walls of the hollow groove cavities of the tire, so that the tire has appropriate rigidity while having good elasticity, and the wheel has good cushioning property and use comfort as a whole.

Description

Technical field [0001] The invention relates to a baby carriage wheel. Background technique [0002] A stroller wheel usually includes a wheel hub and a tire fixed on the wheel hub. In the prior art, on the smaller wheels on the stroller, the tires are usually solid tires made of hard materials. This structure absorbs shock during use. The effect is poor, which affects the comfort of the baby carriage. For wheels with larger gears, the tires usually adopt a structure similar to bicycle wheels, that is, a combination of a tire and a pneumatic inner tube. If the inner tube leaks during use It will affect the use of baby carriages. At the same time, there are more structural parts and production costs. [0003] In order to solve the above technical problems, the applicant invented a baby stroller wheel structure (Chinese patent application with application number 201310698291.1 and publication number 103692866A), in which the tire is a non-inflatable tire, and the tire is opened alon...
