In the figure: 1, inner tube or fabric bag; 2, pressure gas; 3, inflatable ball wall; 4, inflatable ball; 5, inflatable rod; 6, inflatable rod wall; 7, fiber fabric bag; 8, incision; Round hole; 10, sealing patch position. Specific implementation The invention is described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 5, the pneumatic tire leakage protection device of the present invention is applied to a pneumatic tire having a tube or a tubeless tube, and a gas leakage protection device is filled and filled in the pneumatic tire, which includes an inflatable ball 4 or The gas stick 5, but not limited thereto, may be any gas-filled container.

Referring to FIG. 5, the manner of filling the pneumatic tire leakage protection device in the tire having the inner tube is: cutting a slit 8 into the inflatable ball or the inflation rod on the inner side surface of the tubular inner tube, and then in the slit 8 A circular hole 9 is cut or pressed at both ends, and the circular hole 9 functions to prevent the slit 8 from extending to both sides. After the slit 8 is loaded into the inflatable ball and the rod body, an inflatable rod 5 is placed in the slit 8 to withstand At the time of sealing, the slit 8 is finally closed with a rubber skin at the sealing patch position 10 by an existing tire repair method.

Referring to Fig. 4, the manner in which the pneumatic tire leakage protector is filled in the tubeless tire: The fibrous fabric bag 7 filled with the inflatable ball 4 or the inflatable rod 5 is filled in the tire. Among them, the specification of the fiber woven bag should be the size corresponding to the inner size of the tire, and the woven fabric bag 7 can be layered or not layered, and the layered structure is favorable for arranging the inflatable ball and the inflatable rod in a layered manner.

Whether the inflatable ball 4 or the inflatable rod 5 is filled in the inner tube or the fiber fabric bag 7, the inflation pressure in the inflatable ball and the inflatable rod should be the pressure required by the tire, the inflatable ball wall 3 of the inflatable ball 4, and the inflatable rod 5 The thickness of the inflatable rod wall 6 depends on the magnitude of the gas pressure. In the case of a large gas pressure, in order not to increase the wall thickness, a ball or a rod sleeve which is sewn with a rubber or rubber-free cloth layer may be used. Inflated balls, rods outside the body. The filling method in the inner tube or the fiber fabric bag 7 may be any one of a method of loading all the inflating balls, using all of the inflating rods, or mixing the inflating balls and the inflating rods. When using the mixing method, the inflatable ball should be close to the outer diameter surface of the annular tube or bag, and the inflatable rod should be close to the inner diameter surface. When possible, increase the volume of the inflatable ball and the inflatable rod as much as possible. The volume ratio reduces the space outside the ball and the rod, so that there is less chance of leakage after the tire is broken.

The choice of the diameter of the inflatable ball and the rod can be determined according to the specifications, performance and use requirements of various tires. It is better not to be less than the length of the damaged mouth of the tire in general, to prevent the inflatable ball and the rod from being squeezed out from the damaged opening, such as an excessive diameter. When the hard object is punctured to break the inflatable ball and the rod body, the damaged inflatable ball and the rod body have a large spatial position. The volume of the tire is large, and the diameter of the inflatable ball and the rod should be increased accordingly; on the contrary, the volume of the tire is small, and the diameter of the inflatable ball and the rod should be correspondingly reduced. The tire pressure is large, the diameter of the inflatable ball and the rod should be small, the pressure of the tire is small, and the diameter of the inflatable ball and the rod should be large. The diameter of the inflatable ball and the rod can be selected according to the above principles.

The arrangement of the inflatable ball and the rod in the tire: it may be arranged in an orderly manner or in an unordered arrangement. It is the loading of inflatable balls and rods of the same diameter, or the loading of inflatable balls and rods of different diameters. After filling the inner tube or the fabric bag with the inflatable ball and the rod, the tire is sealed, and then the tire is loaded onto the wheel, and the tire is inflated to the required air pressure of the tire.

The inflatable ball and the rod valve are inwardly concave, and are composed of an annular sealing sleeve and a core body. The annular sealing sleeve is used for wrapping the core body, and the core body has an inflatable cylindrical hole and an inflatable flat slit, and is installed in the valve ring seal. Inside the sleeve, the gas enters the ball and the rod body through the inflatable cylindrical hole and the inflatable flat slit in sequence, and the gas is sealed by the contraction of the annular sealing sleeve of the valve and the elastic force of the core body. The valve is made of a rubber material or other similar material.

When a tire equipped with an inflatable ball or a rod is mounted on a wheel, the installation is difficult due to the gas pressure of the gas ball and the rod body. To solve the technical problem, a device for electrically mounting the tire is used. Part of the composition, a part consists of a base, an annular mechanism, a moving device, and an annular inward compression device; the other part consists of a fixed wheel frame, a tire tire edge device, and a rotary balance detecting device. The inner diameter of the annular mechanical sleeve in the ring-opening mechanism should be larger than the tire, and the section width should be greater than the section width of the tire. The moving device moves the ring mechanism into the fixed wheel frame. When an inflatable ball is installed, the rod tire is placed in the ring mechanism, the moving device moves the ring mechanism into the fixed wheel frame, the tire position is aligned with the wheel position, and the ring mechanical pressing device is pressed by the outer radial inner diameter. The inner edge of the tire is brought close to the wheel rim, and the crimping device presses the tire edge into the rim edge, and then the rotation balance of the tire is detected by electronic balance.
