FIG. 2 is a side view of a wheel axle provided with a reinforced rim of the present invention;

the tire comprises a rim 1, a body 11, a tire spigot bulge 12, a rim 13, reinforcing ribs 14, a bead seat 15 and a spoke 2.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model aims at providing a strenghthened type rim to solve the problem that prior art exists, improve the reliable performance of rim, and improve rim intensity.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

Please refer to fig. 1-2.

Example one

As shown in fig. 1-2, the present embodiment provides a reinforced rim, the rim 1 and the spoke 2 form a wheel whole, the rim 1 includes a body 11 and a reinforcing rib 14, wherein the body 11 is cylindrical, the outer wall of the body 11 is provided with a bead seat 15, the bead seat 15 is used for placing a tire, the reinforcing rib 14 is an integral annular rib, the reinforcing rib 14 is annularly arranged on the inner wall of the body 11, and the reinforcing rib 14 is arranged in the area of the bead seat 15.

During the use, the tire is installed in the position of bead seat 15, is supported for the tire by bead seat 15, moreover because the strengthening rib 14 sets up in the region of bead seat 15, makes strengthening rib 14 provide the holding power to bead seat 15 to increase rim 1's support intensity, avoid appearing the problem that bead seat 15 inwards contracts and cause the tire to break away from by bead seat 15 in the use, and then improved rim 1's use reliability.

Example two

As shown in fig. 1-2, the reinforced rim of the present embodiment further has the following features on the basis of the first embodiment:

the rim 1 further comprises a rim 13 and a tire spigot protrusion 12 which are all annularly arranged on the outer wall of the body 11, the rim 13 is arranged on the outer side of the bead seat 15 and connected with the bead seat 15, the tire spigot protrusion 12 is arranged on the inner side of the bead seat 15 and connected with the bead seat 15, and the rim 13 and the tire spigot protrusion 12 are both in an integral annular shape. When the tire is mounted on the bead seat 15, the outer side of the inflated tire contacts the inner side of the rim 13, so that the rim 13 provides axial support for the tire and the tire is prevented from slipping out of the bead seat 15. When the air pressure of the tire is reduced, the moving tire has the tendency of moving towards the inner side of the body 11, the tire spigot bulge 12 blocks the inward moving tire, the gap between the tire and the bead seat 15 is prevented from being increased, and the rapid air leakage of the tire is avoided; and the rim 13 and the tire spigot bulge 12 add a reinforcing structure on the outer side of the rim 1, and further improve the strength of the rim 1.

Further, in order to avoid scratching the tire when the tire contacts the rim 13 and the tire rabbet protrusion 12, the section of the tire and the tire rabbet protrusion 12 is arc-shaped, so that the tire contacts the arc-shaped curved surface, and the risk of tire burst caused by scratching the tire is avoided.

Further, the cross section of the bead 14 is preferably circular arc shape in order to smooth the inner surface of the rim 1.

Further, in order to further improve the supporting strength of the rim 1, the body 11, the bead seat 15, the bead 14, the rim 13 and the bead gore 12 are integrally formed. Preferably, the diameter of the body 11 from the bead seat 15 to the rim 13 is gradually enlarged, so that after the tire is mounted, the radial pressure of the tire on the rim 1 is divided along the bead seat 15, a part of the radial pressure is converted into the axial supporting force on the body 11, the radial pressure on the bead seat 15 is reduced, and the supporting strength of the rim 1 is further improved.

The adaptability that carries out according to actual demand all is in the protection scope of the utility model.

It should be noted that, as is obvious to a person skilled in the art, the invention is not limited to details of the above-described exemplary embodiments, but can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
