Technical Field

[0001] This utility model relates to a tire repair gun for vacuum tires that does not require disassembly. Background Technology

[0002] Currently, tubeless tires are widely used in automobiles, motorcycles, and electric vehicles. The most common repair methods for tubeless tires are external patching and hot patching. External patching involves forcibly inserting a rubber strip into the tire bead that needs repair, which can cause secondary damage to the tire. Hot patching requires disassembling the tire for repair, which is time-consuming and not quick or convenient. Utility Model Content

The gun body has a handle on its lower side, with a handle end connected by a pin. A torsion spring for driving the normally open lower end of the handle is also provided between the handle and the gun body. The upper part of the handle end has a driving end that contacts the movable plate. The upper side of the gun body has an inner cavity, with the first end of the inner cavity providing a connection for the gun head. The gun has two ends, with a tail screw at the end of the inner cavity and a central through hole. The rear end of the inner cavity has openings at the top and bottom. A return pin is vertically inserted through the opening and cuts off the inner cavity. The return pin has a second through hole. The gun barrel is located in the inner cavity. The rear end of the gun barrel passes through the first and second through holes. The front end of the gun barrel has a first limiting ring. A first spring is fitted between the first limiting ring and the two ends and is fitted in the gun barrel. A movable plate is fitted in the middle of the gun barrel. A second spring is fitted between the movable plate and the first limiting ring and is fitted in the gun barrel. A third spring is fitted between the return pin and the movable plate and is fitted in the gun barrel.

[0005] Furthermore, the two ends of the screw have a stepped surface inside the first limiting ring, the gun barrel passes through the third through hole in the center of the stepped surface, and one end of the first spring rests against the stepped surface.

[0006] Furthermore, the moving plate is composed of multiple individual pieces, and the barrel passes through the fourth through hole in the center of the moving plate.

[0007] Furthermore, the upper part of the rear end of the inner cavity is provided with an upper opening, and the lower part of the rear end of the inner cavity is provided with a lower opening. The lower end of the return pin extends out of the lower opening, and the return pin is automatically reset by external driving to align the gun barrel.

[0008] The advantages of this invention are: it can quickly repair tires, adapt to various types of tires, has a simple structure, and is highly safe. Attached Figure Description

A handle 12 is located on the lower side of the gun body 1. A handle 2 is connected to one end of the handle 12 by a pin 13. A torsion spring 6 for driving the normally open lower end of the handle 2 is also provided between the handle 2 and the handle 12. A driving end that contacts the movable plate 10 is located at the upper part of one end of the handle 2. An inner cavity is located on the upper side of the gun body 1, and a double-ended screw 4 for connecting the gun head is located at the first end of the inner cavity. The inner cavity has a tail screw 5 with a first through hole at the center at the end. The inner cavity has openings at the top and bottom. The return pin 11 is vertically inserted into the opening and cuts off the inner cavity. The return pin 11 has a second through hole. The gun barrel 3 is located in the inner cavity. The rear end of the gun barrel 3 passes through the first through hole and the second through hole. The front end of the gun barrel has a first limiting ring 14. A first spring 7 is sleeved on the gun barrel 3 between the first limiting ring 14 and the two end screws 4. A movable plate is sleeved in the middle of the gun barrel. A second spring 8 is sleeved on the gun barrel between the movable plate and the first limiting ring. A third spring 9 is sleeved on the gun barrel between the return pin and the movable plate.

[0012] A tire repair gun for tubeless tires that does not require disassembly, with a drive end consisting of a pin 15.

[0013] A tire repair gun for vacuum tires that does not require disassembly has a stepped surface inside the first limiting ring corresponding to the two end screws. The gun barrel passes through the third through hole in the center of the stepped surface, and one end of the first spring rests against the stepped surface.

[0014] A tire repair gun for vacuum tires that does not require disassembly, wherein the movable piece is composed of multiple individual pieces, and the gun barrel passes through a fourth through hole in the center of the movable piece.

[0015] A tire repair gun for vacuum tires that does not require disassembly has an upper opening at the upper part of the rear end of the inner cavity and a lower opening at the lower part of the rear end of the inner cavity. The lower end of the return pin extends out of the lower opening, and the return pin is automatically reset by external driving to align the gun barrel.

[0016] A tire repair gun for vacuum tires that requires no disassembly can quickly repair tires, is adaptable to various types of tires, has a simple structure, and is highly safe.

[0017] A tire repair gun for tubeless tires that requires no disassembly can be used for temporary tire repair. It is easy to operate and convenient to carry with the vehicle.

[0018] Principle: After inserting the mushroom-shaped rubber bullet into the front section of the double-ended screw, connect the selected gun head to the threaded connection on the outer wall of the front section of the double-ended screw. Then, insert it into the puncture site of the tire. After the thin end of the front section of the gun head is fully pushed into the tire, start firing. Press the lower end of the handle continuously. When the mushroom-shaped rubber bullet is pushed out of the thin end of the gun head by the chamber, press the return pin to return the chamber to the final position. Pull out the tire repair gun. Then, gently pull the stem of the mushroom-shaped rubber bullet with your hand or pliers to make the mushroom umbrella fit tightly against the inner wall of the tire. Then, cut off the excess stem on the outside of the tire. After the tire repair is completed, you can inflate it and drive normally.

[0019] The mushroom-shaped rubber bullet inside the front section of the two-ended screw can be coated with glue; the piercing area can be coated with glue before the gun tip is inserted.

[0020] Pressing down the lower end of the handle moves the drive end at the upper end of the handle, causing the moving plate to move. The moving plate drives the second spring, which in turn drives the chamber with the first limit ring to move forward. Releasing the handle resets the moving plate and the second spring, fixing the rear end of the chamber to the beveled return pin, and the chamber remains stationary. Continuing the above actions, the mushroom-shaped rubber bullet is pressed out of the barrel by the narrow end of the bullet head. Then, pressing down the lower end of the return pin aligns it, and the first spring drives the chamber to return to its original position.

[0021] When the lower end of the handle is pressed and released, the second spring moves, causing the pressure of the third spring to become unbalanced, which in turn causes the return pin to form a slope to fix the barrel.

[0022] A tire repair gun for tubeless tires that requires no disassembly, used for repairing tubeless tires on motorcycles, electric vehicles, tricycles, cars and other vehicles.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this invention is defined by the appended claims rather than the foregoing description, and it is therefore intended to include all variations falling within the meaning and scope of the equivalents of the claims within this invention.
