Example Embodiment

[0013] Example 1, see figure 1 with figure 2 Shown: A free tire repair gun for automobile vacuum tires, including a gun body 10 and a barrel 11. The gun body 10 is generally made of aluminum or hard plastic, which is composed of the left and right gun bodies. The gun barrel 11 is arranged in the gun channel; the gun body 10 is provided with a limiting end surface that restricts the barrel 11 from sliding out. The limiting end surface can be a step or a wide to narrow slope. The barrel 11 is generally made of steel. The barrel 11 is provided with an electric heating device. The electric heating device is composed of a heating plate 19, a power supply wire and an electric control switch. The heating plate 19 is located on the outer circumference of the barrel 11, The control switch is located on the gun body 10, and the power wire is electrically connected to the heating plate 19 through the electric control switch; in this way, after the power wire is energized and the electric control switch is turned on, it can heat the heating plate 19, and the heating plate 19 can transfer heat To the inside of the barrel 11, the gel is melted to make it thick. The gun body 10 is also provided with a glue injection needle tube 12, a positioning nut 13, a push rod 14, a return spring 15, a gear 16 and a trigger 17, and there is a discharge chamber in the gun barrel 11, and there are two discharge chambers. The end through structure, and the front end has a connecting thread, the glue injection needle tube 12 is screwed on the thread part and the inside has a discharge pipe that penetrates the front and back ends, and the discharge pipe is connected to the discharge chamber. This separable The connection structure can easily replace the glue injection needle tubes 12 of different specifications to meet the repair requirements of different sizes of tire holes. The discharging chamber can place solid or thick glue, and the discharge pipe in the glue injection needle tube 12 is pushed by the push rod 14 to squeeze the glue out. The push rod 14 is inserted and sleeved in the discharge chamber, and its rear end has a knob 141. The glue can be squeezed out by the active or passive movement of the push rod 14; the external thread of the positioning nut 13 is screwed to the gun body 10 On the end face, the external thread of the push rod 14 is screwed to the internal thread of the positioning nut 13; this connection method is not only convenient for installation, but also adjusts the relative position of the push rod 14 in the discharge chamber, which improves the convenience of use. There is a push block at the front end of the push rod 14, and the end surface of the push block is provided with a positioning blind hole, which communicates with the discharge chamber; the positioning blind hole can position the solid colloid inside it to prevent deviation during use phenomenon. The return spring 15 is inserted and sleeved on the outside of the push rod 14 with one end abutting on the outer end surface of the barrel 11, and the other end abutting on the positioning nut 13, the return spring 15 can be moved after the barrel 11 is moved It returns to its original position. Of course, the aforementioned abutment structure with the barrel 11 can also be: a snap ring is provided inside the barrel 11, and the return spring 15 abuts on the end surface of the snap ring. The trigger 17 is pivotally connected to the gun body 10 through a pin, and its end has an active rack 171. The gear 16 is pivotally connected in the gun body 10 through a pin. A driven rack 111 is provided on the outer circumference of the barrel 11 , One side of the gear 16 meshes with the driving rack 171, and the other side meshes with the driven rack 111; in use, insert the rubber injection needle tube 12 into the tire hole of the tire and pull the trigger 17, in the gear 16 Driven by the drive, the driven rack 111 will move backwards, which drives the barrel 11 and the glue injection needle tube 12 to move backwards. Since the push rod 14 is in a static state, the push block on it compresses the discharge chamber and The glue is extruded from the glue injection needle tube 12, and when the glue injection needle tube 12 exits the tire hole, the tire repair is completed; the trigger 17 is released and the barrel 11 returns to its original position under the elastic force of the return spring 15. This structure not only eliminates the need to disassemble the vacuum tire, saves labor and is convenient for repairing the tire, but also prevents secondary damage to the tire. The gun body 10 is provided with a limit mechanism that limits the rotation of the barrel 11, and the structure of the limit mechanism is: a positioning pin is provided on the gun body 10, a chute 18 is provided on the outer circumference of the barrel 11, and a positioning pin The post is positioned in the chute 18; in this way, the positioning pin can play a better positioning function, and it can only move the barrel 11 but cannot rotate.

Example Embodiment

[0014] Embodiment 2. Embodiment 2 is substantially the same as Embodiment 1, and the difference lies in: the structure of the limit mechanism is: a chute is provided on the gun body 10, and a positioning pin is provided on the barrel 11, and the positioning pin is Positioned in the chute; it can also achieve the effect of embodiment 1.
