Abstract

The utility model discloses an explosion-proof structure of wheel frame is equipped with the fin at the frame groove inner edge that wheel frame scarf joint tire, and the fin is one end towards frame groove bottom edge, and the end is to frame groove outer fringe in addition to prevent that the tire from jumping out from the tire inner edge because of pressurized.

Description

Explosion-proof structure of the wheel frame

The utility model relates to a wheel frame, in particular to an explosion-proof structure of the wheel frame.

Generally, the frame groove of the wheel frame of a bicycle is an inverted trapezoid, which is used to limit the two open rims of the tire. For smooth surface, when tire is subjected to heavy pressure suddenly, be easy to force tire to pop, if the structure of tire is to establish the structure of inner tube of a tube again in the cover tire, the shortcoming that cover tire is easy to pop will take place equally.

The purpose of the utility model is to provide an explosion-proof structure of the wheel frame to prevent the tire from bouncing from the inner edge of the tire due to pressure.

In order to achieve the above object, the solution of the present invention is: an explosion-proof structure of the wheel frame, in which a convex rib is provided on the inner edge of the frame groove of the wheel frame embedded with the tire.

In the above-mentioned explosion-proof structure of the wheel frame, one end of the protruding rib faces the bottom edge of the frame groove, and the other end faces the outer edge of the frame groove.

After adopting the above-mentioned scheme, the main purpose is to provide ribs on the inner edge of the frame groove where the wheel frame is embedded with the tire, so as to increase the force of the wheel frame to bite the tire, so as to prevent the tire from bouncing from the inner edge of the tire due to pressure.

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

Fig. 1 is the perspective view of the utility model example one;

Fig. 2 is the sectional view of the utility model example one;

Fig. 3 is the implementation figure of the utility model example one;

Fig. 4 is the perspective view of the utility model example two;

Fig. 5 is a perspective view of Example 3 of the present utility model.

As shown in Figure 1 and Figure 2, the first example of the utility model is that the inner edge of the frame groove 11 where the wheel frame 1 is embedded with the tire 2 is continuously provided with convex ribs 12 at intervals, and one end of the convex rib 12 is facing the bottom edge of the frame groove 11, The other end is toward the outer edge of the frame groove 11. During implementation, as shown in Figure 3, the ribs 12 will embed the two open rims 21 of the tire 2, increasing the force of the wheel frame 1 to bite the tire 2, so as to prevent the tire 2 from being compressed due to pressure. Bounce from the rim 21 of the tire 2.

And the form of the convex rib 12 of the utility model example one is not limited to continuous interval setting, also can be as shown in Figure 4 and Figure 5, wherein, the convex rib 12A in the frame groove 11A of the wheel frame 1A of this example two is two The strips are adjacently juxtaposed as a unit, and then arranged at continuous intervals in this unit. As for the ribs 12B in the frame groove 11B of the wheel frame 1B of Example 3, they are continuously arranged side by side. In addition, it is also feasible to arrange at unequal intervals.

Compared with conventional products, the utility model does have better grip and bite force, so that the tire 2 is more resistant to pressure impact and is not easy to pop from the wheel frame 1.
