Abstract

A handcart wheel arranges tread fixing holes around a wheel core. A part of a wheel tread is embedded into the tread fixing hole. A center hole of the wheel core is fixed with an annular ball bearing. A shaft sleeve is embedded onto the bearing from its two sides. An outer side of the shaft sleeve is arranged with a dustproof guard. The tread and the wheel core, and the wheel core and the bearing are fixed through injection molding. The utility model has the technical effects below: Firstly, the annular ball bearing is adopted to ensure more flexible and quiet rotation and long service life. Secondly, an injection molding machine is utilized to firmly position the tread with the wheel core, the bearing with the wheel core through injection molding to effect prevent moving or falling down. Thirdly, the tread fixing hole is arranged around the wheel core to make the tread firmly fixed on the wheel core, thus effectively preventing the tread falling from the wheel core after long-time operation. Fourthly, the tread fixing hole around the wheel core can effectively reduce noise during wheel rotation. Finally, injection molding can improve production efficiency and reduce production cost.

Description

Trolley wheel

Affiliated technical field

The utility model relates to a kind of wheel.

Background technology

It is effort that the not employing bearing that the wheel that uses on hand barrow at present has, this hand barrow use one, is not very flexible; The 2nd, easily wearing and tearing and damaging; The employing that has the limit bearing, this limit bearing also is easy damage, maintenance capacity is big.

Summary of the invention

It is low that the purpose of this utility model provides a kind of cost, durable hand barrow pavilion wheel.

The purpose of this utility model is achieved by the following technical solution, a kind of trolley wheel has the tyre surface fixed orifice at the periphery of core wheel, and the part edge of tyre surface is enclosed within the tyre surface fixed orifice, be fixed with radial ball bearing in the medium pore of core wheel, axle sleeve is enclosed within on the bearing from the both sides edge.The outside at axle sleeve is fixed with dust guard.Tyre surface and core wheel, core wheel and bearing adopt injection mo(u)lding to fix.

The utlity model has following technique effect, the one, it is more flexible, quieter to adopt radial ball bearing to rotate, long service life; The 2nd, adopt the injection machine injection mo(u)lding, tyre surface and core wheel, bearing and core wheel firm position can not move, and perhaps drop; The 3rd, have the tyre surface fixed orifice at the core wheel periphery, can make firm being fixed on the core wheel of tyre surface, guaranteed effectively that after working long hours tyre surface can not fall down from core wheel; The 4th, the tyre surface fixed orifice that the core wheel periphery has is the noise when reducing the wheel rolling effectively; The 5th, injection mo(u)lding can be enhanced productivity, and reduces production costs.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an A-A cross section view of the present utility model;

Fig. 2 is a B-B cross section view of the present utility model;

The specific embodiment

As shown in Figure 1 and Figure 2; A kind of trolley wheel, periphery at core wheel 2 has tyre surface fixed orifice 6, the part edge of tyre surface 1 is enclosed within the tyre surface fixed orifice 6, be fixed with radial ball bearing 4 in the medium pore of core wheel 2, axle sleeve 5 is enclosed within bearing 4 from the both sides edge, be fixed with dust guard 3 in the outside of axle sleeve 5, tyre surface 1 and core wheel 2, core wheel 2 adopts injection mo(u)lding to fix with bearing 4.
