Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. 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.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, two-piece double-sided anticreep wheel hub, wheel hub is including rim 1, radials 2 and clamping ring 3 integrated into one piece, the one end of rim 1 is equipped with interior rim 4, and the clamping ring 3 is connected through a plurality of screws 5 to the other end of rim 1, is equipped with outer rim 6 on the clamping ring 3, installs tire 7 on rim 1, the cover has anticreep ring 8 on rim 1, and tire 7 is including two wheel lips 9, and two wheel lips 9 press from both sides tightly respectively between anticreep ring 8 and interior rim 4, between anticreep ring 8 and outer rim 6. When the wheel continues to run after the tire 7 leaks, the two sides of the anti-drop ring 8 continuously push against the wheel lips 9, so that the tire 7 cannot drop off in the running process, the tire 7 can continuously protect the wheel hub, and loss is reduced. And a sealing ring 16 is arranged at the joint of the rim 1 and the pressing ring 3.

Alternatively, as shown in fig. 6, the web 2 is integrally formed with the rim 1.

Further, the pressing ring 3 is provided with an air valve 10, the inner surface of the anti-falling ring 8 is provided with an air groove 11, the air groove 11 is communicated with the outer surface of the anti-falling ring 8 through an air hole 12, and the air valve 10 is communicated with the air groove 11. When the valve 10 is inflated, gas enters the tire 7 from the air groove 11 and the air hole 12.

Further, the wheel rim 1 is in clearance fit with the anti-drop ring 8. The design can prevent the anti-drop ring 8 from moving to cause the communication between the valve 10 and the air groove 11 to be blocked. The anti-slip ring 8 is mainly fixed on the hub by the clamping force of the inner rim 4 and the outer rim 6 on two sides. Because a gap exists between the rim 1 and the anti-drop ring 8, air coming out of the inflating valve 10 can enter the tire 7 through the gap, the air groove 11 and the air hole 12 all the time.

Alternatively, as shown in fig. 3, the inner surface of the anti-drop ring 8 is provided with a plurality of long grooves 13 uniformly spaced, wherein one of the long grooves 13 is provided as an air groove 11. The main function of the elongated slot 13 is to reduce weight and avoid the addition of the anti-slip ring 8 from adding excessive weight to the hub. Two ends of the long groove 13 are also communicated with two sides of the anti-drop ring 8.

Alternatively, as shown in fig. 4, the air groove 11 may be an annular groove, which is coaxial with the slip-off preventing ring 8. In this way, the problem that the anti-drop ring 8 may move to cause the communication part of the valve 10 and the air groove 11 to be blocked can be solved, and meanwhile, the anti-drop ring 8 can be lightened.

Or, as shown in fig. 5, the number of the air grooves 11 is multiple, the air grooves 11 are arranged in a row around the axis circumference of the anti-drop ring 8, and each air groove 11 is communicated with the outer surface of the anti-drop ring 8 through the air hole 12. This design eliminates the need to align the air groove 11 with the valve 10 when installing the separation preventing ring 8, and also allows the separation preventing ring 8 to be reduced in weight.

Furthermore, the side of the anti-slip ring 8 close to the inner rim 4 is provided with an inner supporting inclined surface 14 matched with the inner rim 4, and the side of the anti-slip ring 8 close to the outer rim 6 is provided with an outer supporting inclined surface 15 matched with the outer rim 6. So that the sides of the anti-slip ring 8 can grip the wheel lip 9 of the tire 7.

Further, the anti-drop ring 8 is made of rubber.

It is worth mentioning that the technical features such as rubber that the utility model discloses a patent application relates to should be regarded as prior art, and the concrete structure of these technical features, theory of operation and the control mode that may involve, spatial arrangement mode adopt the conventional selection in this field can, should not be regarded as the invention point of the utility model discloses a, the utility model discloses a do not do further specifically expand the detailed description.

Having described in detail preferred embodiments of the present invention, it is to be understood that modifications and variations can be made by persons skilled in the art without inventive faculty, and therefore all technical solutions which can be obtained by a person skilled in the art based on the concepts of the present invention through logic analysis, reasoning or limited experimentation will fall within the scope of protection defined by the claims.
