Description

tyre-continuing device

technical field

The utility model relates to the structure of a motor vehicle tire, in particular to a tire continuing device.

Background technique

At present, the tires of ordinary cars are made up of pneumatic tires and wheel hubs, and the tires are inflated to carry the vehicle and keep the vehicle running safely and smoothly. And when the tire is punctured or blown out, the normal safe running of the vehicle cannot be maintained because of the tire leaking air. Especially for the cash transport vehicle that suffers from tire leaking failures during the execution of tasks, one will seriously hinder the operation of the cash transport vehicle, and secondly, the breakdown of the cash transport vehicle for some reason may cause criminals to take advantage of it. It may bring unsafe hidden dangers to the lives of escorts and financial property. Therefore, how to ensure the safe running of vehicle tires under any circumstances is meaningful.

Utility model content

The purpose of this utility model is to provide a tire continuing device that can still maintain the normal running of the vehicle after the tire leaks air.

The purpose of this utility model is achieved in this way, a tire continuation device, which is characterized in that the two ends of the two semi-circular hoofs are connected to form a complete ring; It is a step-type overlapping platform, with a through hole in the center of the platform, a limit baffle on the inner ring of the semi-circular shoe, and a knife relief groove on the outside of the limit baffle ring; the semi-circular shoe is connected by a bolt assembly , the bolt assembly is composed of connecting bolts, anti-loosening clips, limit sleeves and screws. The loose card sleeve is placed on the hexagonal side of the connecting bolt head and the connecting nut, and the loose card is fixed on the shoe by screws; the shape of the limit sleeve is conical, the conical surface of the limit sleeve is provided with knurling, and the inner surface of the limit sleeve The hole is matched with the connecting bolt; the anti-loosening card is provided with two parallel folding surfaces connected as a whole, the lower folding surface is provided with an open groove, and the upper folding surface is provided with hexagonal holes; the two sides of the semi-circular hoof are evenly and symmetrically provided with Several blind holes.

The utility model has the advantage that the running device implemented according to this scheme is installed on the wheel hub with an interference fit, and when the tire is punctured or blown out, the running device installed on the wheel hub can be pressed tightly to replace the pneumatic tire to maintain The continuation of the vehicle, also due to the continuation of the vehicle, can effectively avoid and prevent criminals from taking advantage of it. The utility model is reasonable in structure, simple and convenient, and has certain practical significance.

Detailed ways

Further specific description will be made in conjunction with the accompanying drawings. This continuation device 10 forms a complete ring by connecting the two ends of the two semicircular hoofs 1 through bolt assemblies. There are overlapping platforms 5 that are mutually stepped, the center of the platform is provided with a through hole 50, and the inner ring of the semi-circular shoe 1 is provided with a limit baffle 2, and the limit stop 2 is mainly used for installation on the wheel hub. The axial positioning of the tool undercut 3 is a process requirement during manufacturing. The two ends of the two semi-circular hoofs 1 are lapped and connected by a bolt assembly. The bolt assembly is composed of a connecting bolt 6, an anti-loosening card 7, a limit sleeve 8 and a screw 9. The shape of the limit sleeve 8 is made into a tapered shape. And the conical surface is shaped on knurling 81, and the inner hole 80 of the limit sleeve 8 cooperates with the connecting bolt 6. When assembling, the two limit sleeves 8 are placed from the two ends of the through hole 50 at the connecting end of the two semi-circular shoe pieces 1 respectively. Insert the connecting bolt 6 into the hole 80 of the limit sleeve 8. After tightening the connecting bolt 6, insert the anti-loosening card 7 into the hexagonal edge of the connecting bolt head or the connecting nut, and then use the screw 9 to secure the anti-loosening card 7 Fixed on the hoof 1, the function of the anti-loosening card 7 is to prevent the loosening of the connecting bolt 6 during operation. The open slot 710 is used for the penetration of the screw 9 , and the upper folded surface 72 is provided with a hexagonal hole 720 for being inserted into the hexagonal side of the bolt. In order to reduce the weight of the shoe, several blind holes 4 are evenly and symmetrically formed on both sides of the semicircular shoe 1 .

Fig. 6 and Fig. 7 are respectively the state schematic diagrams of tire normal running and running after blowing out the air, the continuation device 10 of the present utility model is press fit device on the wheel hub 11, and 12 is the pneumatic tire, after the tire 12 blows out the air, this continuation line The device 10 is closely attached to the tire 12 so that the running of the vehicle can be continued. Therefore, the utility model has special effects on vehicles used for some special purposes or special occasions.
