Description

An environmentally friendly caster

technical field

The utility model relates to an industrial and civilian caster, in particular to an environment-friendly caster.

Background technique

At present, the casters used in industry and civil use are generally made of rubber, which has the defects of easy bursting, easy foaming on the surface, and poor gloss of the appearance; it is easy to leave marks on the ground during use; the rubber material itself has peculiar smell and is not recyclable, which is environmentally friendly. Poor performance; and once the car body is relatively heavy, it will shift and the stability is not good.

Contents of the invention

The purpose of the utility model is to provide an environment-friendly caster with a reasonable design structure, high bearing capacity and no deviation when the vehicle body is heavy, aiming at the defects of the above-mentioned prior art.

In order to achieve the above object, the technical solution adopted by the utility model is: an environmentally friendly caster, including an inner core and a wheel sleeve tightly wrapped around it, with a shaft hole in the middle of the inner core, and the radial sides of the inner core are stepped. Conical shape and arranged symmetrically along the center of the shaft hole. The purpose of the radially stepped circular frustum-shaped structure of the inner core is to enhance its stability when moving and to avoid deviation. Therefore, the utility model has a strong load-bearing capacity and has a beautiful appearance.

In order to facilitate the installation of the inner core and the outer casing, notches are symmetrically provided on the periphery of the inner core along the center of the shaft hole.

In order to increase the hardness of the utility model, the inner core is made of PP material, and the wheel sleeve is made of PU material. Since PP and PU have no peculiar smell and are recyclable materials, the environmental protection of the utility model is also increased, and bubbles and bursts on the surface are avoided, and black marks will not be left on the ground during use, which is more convenient to use .

The beneficial effects of the utility model are: compared with the prior art, the utility model has the advantages of reasonable structural design, high load-bearing capacity, beautiful appearance lines, convenient use and good environmental protection performance.

Description of drawings

Fig. 1 is a sectional view of the environmental protection caster described in the utility model;

FIG. 2 is a side view of the inner core shown in FIG. 1 .

In the figure: 1 wheel sleeve, 2 inner core, 2.1 radial side surface of inner core, 2.2 shaft hole, 2.3 notch.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.

An environmentally friendly and recyclable caster wheel as shown in Figure 1-2 includes an inner core 2 and a wheel cover 1 tightly wrapped outside the inner core 2 . A shaft hole 2.2 is provided in the middle of the inner core 2, and the radially side surfaces 2.1 of the inner core are in the shape of stepped conical cones and arranged symmetrically along the center of the shaft hole 2.2. In order to facilitate the installation of the inner core 2 and the wheel sleeve 1, a notch 2.3 is provided symmetrically on the periphery of the inner core 2 along the center of the shaft hole 2.2. Among them, the inner core is made of PP material, and the wheel cover 1 is made of PU material. After the inner core 2 is manufactured, pressurize and then connect the wheel cover 1 and the inner core 2. The connection between the wheel cover 1 and the inner core 2 is not obvious. The gap, so the appearance lines are beautiful.

Compared with the casters made of a single rubber material in the past, the utility model adopts the combination of PP inner core and PU wheel sleeve, which has the advantage that when the load-bearing capacity of itself is relatively large, the places it passes will not be made of rubber. The casters leave black marks, and the width of the casters is increased, which strengthens the contact area with the ground and strengthens its load-bearing capacity, which is stronger than ordinary casters. When the gravity of the car body is relatively large, it can also move smoothly and smoothly, and it is guaranteed that the car body will not deviate.

The above-described embodiment is only a kind of preferred embodiment of the utility model, and the usual changes and replacements carried out by those skilled in the art within the scope of the technical solutions of the utility model should be included in the protection scope of the utility model Inside.
