Description

Airless tire supporting device

technical field

The utility model relates to an auxiliary equipment, in particular to an airless tire supporting device.

Background technique

With the improvement of living standards, more and more people have replaced their bicycles with electric vehicles. While enjoying the convenience, we have to face another kind of trouble. That is, because the mass of an electric vehicle is larger than that of a bicycle, and most of them are designed with the motor and battery located in the middle and rear of the vehicle, when the tire of the electric vehicle is punctured or the air pressure is too low, the heavy body makes it very difficult to push, which takes time and effort. When the rear wheel is forced to push without air, the inner and outer tires are crushed and crushed, which shortens their service life, causes greater losses, and increases the cost of use.

Utility model content

The purpose of this utility model is to provide an airless tire support device to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A supporting device for an airless tire, comprising a base; four universal wheels are uniformly installed on the bottom of the base, and the base and the universal wheels are connected by a lifting device. The right end of the base is welded with a baffle. The middle position of the left end of the base is provided with a through hole matched with the connecting bolt, the connecting bolt passes through the through hole, the flap is connected with the base through the connecting bolt, and the flap can rotate around the connecting bolt.

As a further solution of the utility model: the universal wheel includes a roller bracket, and the lower end of the roller bracket is connected with a roller through a bolt; the upper left side of the roller bracket is fixedly provided with a connecting plate, and the lifting device is fixed on the connecting plate by fastening bolts. The upper end on the right side of the roller bracket is provided with a brake.

Compared with the prior art, the beneficial effect of the utility model is that the utility model has simple structure, reasonable design, convenient use and low production cost, and is suitable for tires of most mainstream specifications. It can support the airless tires, avoid the tires from being punctured or when the air pressure is too low, which will cause the inner and outer tires to be crushed and crushed, which improves the service life of the tires, reduces losses, and saves use costs.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1 to 4. In the embodiment of the present utility model, an airless tire supporting device includes a base 1; four universal wheels 5 are uniformly installed on the bottom of the base 1, The room is connected by lifting device 6. The right end of the base 1 is welded with a baffle plate 3 . The middle position of the left end of the base 1 is provided with a through hole matched with the connecting bolt 2. The connecting bolt 2 passes through the through hole.

Further, the universal wheel 5 described in the utility model includes a roller bracket 54, the lower end of the roller bracket 54 is connected with a roller 51 by a bolt; on the connecting plate 53. The upper end on the right side of the roller bracket 54 is provided with a brake 52 .

The utility model utilizes the knowledge of physical inclined planes and levers to uniquely design inclined planes, so that the wheels can be pushed onto the device conveniently, and even women with small physical strength can easily use it. It is partially welded and partially detachable for easy portability. Through actual measurement, the utility model is also applicable to motorcycle tires.

The utility model has the advantages of simple structure, reasonable design, convenient use and low production cost, and is suitable for tires of most mainstream specifications. It can support the airless tires, avoid the tires from being punctured or when the air pressure is too low, which will cause the inner and outer tires to be crushed and crushed, which improves the service life of the tires, reduces losses, and saves use costs.

The working principle of the utility model is:

When in use, the airless tire supporting device is placed on the ground, the universal wheel 5 is locked by the brake 52, and the baffle plate 3 is pressed against the step. If the step is higher, the base is lifted by the lifting device 6 High, turning over the flap 7, the tire 8 enters the base 1 through the flap 7.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from all points of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to be included in the claims All changes within the meaning and range of equivalents of the required elements are included in the present invention.
