Description

Luggage case wheel

Technical Field

The utility model relates to a tire technical field, concretely relates to suitcase wheel.

Background

A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. Generally mounted on a metal rim, and is capable of supporting a vehicle body, buffering external impact, achieving contact with a road surface and ensuring the driving performance of a vehicle. Tires are often used under complex and severe conditions, which are subjected to various deformations, loads, forces and high and low temperature effects during running, and therefore must have high load-bearing, traction and cushioning properties. At the same time, high abrasion resistance and flexibility resistance, and low rolling resistance and heat build-up are also required. Half of the world's rubber usage is for tire production, and the ability of tires to consume rubber is seen. However, the tire on the market at present has a poor inner supporting effect and is easy to deform the tire body.

Disclosure of Invention

In view of the above problems, the present invention is directed to a luggage wheel with a certain cushioning ability and less deformation.

The purpose of the utility model is realized with the following mode:

a luggage wheel comprising:

a carcass;

the base disc is arranged in the middle of the tire body through a plurality of support rods;

wherein, the bracing piece includes:

a first connecting body connected with the inner side of the carcass;

a third connector connected to an outer side of the base plate;

a second connector connected between the first connector and the third connector.

Furthermore, a side arc surface is formed outside the first connecting body, and a flange is arranged in the middle of the upper end of the side arc surface.

Further, the flange is fixedly connected with the lower end of the second connecting body.

Further, the third connector comprises a U-shaped portion and a pair of bending portions, the U-shaped portion is fixedly connected with the upper end of the second connector, the pair of bending portions are symmetrically connected to the U-shaped portion, and the bending portions are connected with the outer side of the base plate.

Further, a cavity is formed between the pair of bent portions and the base plate.

Furthermore, a semicircular groove is formed in the U-shaped part.

Furthermore, a rotating shaft penetrates through the middle of the base plate.

Further, the second connecting body and the third connecting body are made of rubber materials.

The utility model has the advantages that: because be provided with first connector, third connector and second connector on the bracing piece, played certain supporting role to the matrix, make the utility model discloses have certain buffer capacity, and non-deformable.

fig. 3 is a schematic structural view of a third connecting body of the present invention.

The notation in the figure is: the support rod comprises a base plate 10, a rotating shaft 11, a tire body 20, a support rod 30, a first connecting body 31, a side arc surface 311, a flange 312, a second connecting body 32, a third connecting body 33, a U-shaped part 331, a semi-circular groove 3311, a bent part 332 and a cavity 333.

Detailed Description

The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.

With reference to fig. 1 to 3, a luggage wheel as shown in fig. 1 and 2, comprising: the base disc 10 is arranged in the middle of the tire body 20 through a plurality of support rods 30, wherein each support rod 30 comprises a first connecting body 31, a third connecting body 33 and a second connecting body 32, and the first connecting body 31 is connected with the inner side of the tire body 20; the third connecting body 33 is connected to the outer side of the base plate 10; the second connecting body 32 is connected between the first connecting body 31 and the third connecting body 33.

Preferably, a side arc surface 311 is formed outside the first connecting body 31, and a flange 312 is disposed in the middle of the upper end of the side arc surface 311. With the above structure, the first connecting body 31 can support the tire body 20 and play a certain role in buffering.

Preferably, the flange 312 is fixedly connected to the lower end of the second connecting body 32.

Preferably, the third connecting body 33 includes a U-shaped portion 331 and a pair of bent portions 332, the U-shaped portion 331 is fixedly connected to an upper end of the second connecting body 32, the pair of bent portions 332 are symmetrically connected to the U-shaped portion 331, and the bent portions 332 are connected to an outer side of the base plate 10. The above structure is provided, which is beneficial to improving the buffering effect of the third connecting body 33 on the inner part of the tire body 20.

Preferably, a cavity 333 is formed between the pair of bent portions 332 and the base plate 10.

As shown in fig. 3, a semicircular groove 3311 is formed in the U-shaped portion 331.
