This process can replace the traditional rivet installation process, save manpower, and improve production efficiency. At the same time, the concentricity of the product is improved, the swing and jump of the caster when rolling will be reduced, the quality is more reliable, and the service life is improved.

Description

A snap-on caster

technical field

The utility model relates to a wheel component for a movable vehicle, in particular to a clamping type caster.

Background technique

With the rise of the industrial revolution, more and more equipment needs to be easy to move, and the application of casters in the world has become more and more extensive. All walks of life are almost inseparable from casters. In modern times, with the continuous development of science and technology, equipment has become more and more multi-functional and high-utilization, and casters have become an indispensable part. The development of casters has become more specialized and has become a special industry. Casters are used in a wide range of applications and involve almost any industry. According to the needs of different industries, people continue to invent all kinds of casters. The hub of the caster, as the core component of the caster, is usually formed by riveting two spokes. However, in the existing production process, workers need to put The rivets are inserted into the holes of the two spokes one by one, and then docked. This docking method not only has low production efficiency, but also has low concentricity of the two spokes after riveting, poor quality and short practical life.

Utility model content

In order to solve the above problems, the purpose of the utility model is to provide a caster wheel with clamping type, simple splicing and simple structure.

The technical scheme that the utility model adopts for solving its technical problem is:

A clip-on caster wheel includes a first spoke, a second spoke and an outer wheel, the first spoke and the second spoke are combined to form a hub through a snap-fit structure, and the outer wheel is arranged on the outer circumference of the hub.

Further, the buckle structure includes an annular boss or an annular groove arranged on the first spoke and an annular groove matched with the annular boss or arranged on the second spoke. Fitting ring boss.

Still further, the buckle structure is formed by crimping the annular boss and the annular groove.

Further, a shaft hole is provided at the center of the hub, and a shaft sleeve and a bearing are sequentially installed in the shaft hole from inside to outside.

Still further, the bearing is a roller bearing.

Further, both the first and second spokes are bowl-shaped, and the first and second spokes are combined with their bowls facing outwards.

Further, the outer wheel is made of rubber.

The beneficial effect of the utility model is that: because the two spokes of the clamping caster of the utility model are combined into a hub through a buckle structure, the buckle structure includes an annular boss arranged on one of the spokes and an annular boss arranged on the other spoke. The annular groove on the upper is matched with the annular boss. In the production process, the ring-shaped bosses of the spokes are combined with the ring-shaped grooves. After the combination is completed, the joint parts are crimped, so that a stable buckle structure is formed between the two spokes. This process can replace the traditional rivet installation. process, saving manpower and improving production efficiency. At the same time, the concentricity of the product is improved, the swing and jump of the caster wheel will be reduced when rolling, the quality is more reliable, and the service life is improved.

Detailed ways

Referring to Fig. 1 to Fig. 5, Fig. 1 to Fig. 5 are specific structural schematic diagrams of an embodiment of the utility model, as shown in the figure, a snap-in type caster includes a first spoke 1, a second spoke 2 and an outer wheel 3 , the shape of the first spoke 1 and the second spoke 2 is bowl-shaped, the first spoke 1 and the second spoke 2 are combined with their bowls facing outwards, and the gap between the first spoke 1 and the second spoke 2 A hub is combined by a buckle structure. In the present utility model, the buckle structure includes an annular boss 11 arranged on the first spoke 1 and an annular boss 11 arranged on the second spoke 2 The matching annular groove 21, of course, in other embodiments, the buckle structure may include the annular groove 21 arranged on the first spoke 1 and the annular groove 21 arranged on the second spoke 2 The matching annular boss 11, in the production process, the annular boss 11 and the annular groove 21 are assembled to form a stable buckle structure by crimping, this process can replace the traditional rivet installation process, Save manpower and improve production efficiency. At the same time, the concentricity of the product is improved, the swing and jump of the caster wheel will be reduced when rolling, the quality is more reliable, and the service life is improved. Further, the outer wheel 3 is arranged on the outer circumference of the hub, and the outer wheel 3 is made of soft material. Preferably, the outer wheel 3 is made of rubber. Since the two spokes combined into the hub are bowl-shaped and the bowls of the two spokes face outwards and are combined with their backs facing each other, a groove is formed on the outer side of the hub formed by combining the two spokes. The outer wheel 3 is arranged on the above-mentioned groove position, because of the existence of the groove position, the outer wheel 3 is not easy to slip out, which is more practical and reliable. At the same time, a shaft hole 4 is arranged in the hub, and a shaft sleeve 5 and a bearing 6 are sequentially installed in the shaft hole 4 from inside to outside. Preferably, in the present utility model, the bearing 6 is a roller bearing.

As shown in Fig. 3, Fig. 4 and Fig. 5, in the actual production process, the first wheel spoke 1 with the annular boss 11 is installed in the outer wheel 3 made of rubber, and then the inner hole is covered with The bearing 6 of the axle sleeve 5 is put into the shaft hole 4 of the spoke 1, and then the second spoke 2 with the annular groove 21 is put into the corresponding position, and the assembly process before the crimping of the hub is completed. Finally, the assembled caster is completed on the machine tool to complete the crimping process of the annular boss 11 and the annular groove 21, so as to form a stable buckle structure.

The above descriptions are only the preferred implementation modes of the present utility model, as long as the technical solutions that achieve the purpose of the utility model by basically the same means all fall within the scope of protection of the utility model.
