Description

Technical Field

[0001] The present invention relates to a tire repair device and an adhesive coating device.

Background Art

[0002] As a device currently provided for repairing damaged tires, there is one that uses an air source device and an adhesive coating device in combination. If necessary, the user connects the air inlet manifold of the adhesive coating device to the air outlet connector of the air source device, and connects the outlet pipe of the adhesive coating device to the air nozzle of the damaged tire. By supplying air to the adhesive coating device through the air source device, the colloid in the adhesive coating device is extruded using air pressure and enters the damaged tire, thereby achieving the purpose of tire repair.

[0003] As can be seen from the above, in the tire repair technology and process, adhesive coating and air injection are required, but the existing working methods are still carried out separately. With the existing construction methods, the construction efficiency cannot be improved.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention provides an adhesive coating device and a tire repair device capable of injecting air or applying an adhesive to a tire.

Means for Solving the Problems

[0005] The tire repair device of the present invention is for use in injecting air or applying an adhesive to a tire. The tire repair device includes a box body, an air supply source, and an adhesive application device. The adhesive application device includes a tank, a cover, and an intermediate pipe. The tank has a storage chamber for holding a colloid. The cover is assembled to the tank. The cover has a circular pipe, an outlet pipe, and an air inlet pipe. The outlet pipe and the air inlet pipe each extend from the circular pipe and communicate with the circular pipe. The air supply source is connected to the air inlet pipe and provides gas to the air inlet pipe. The intermediate pipe is disposed movably within the circular pipe, and the circular pipe and the intermediate pipe are coaxially connected to each other. The intermediate pipe has a pair of seal portions and a neck portion located between the seal portions. The outer diameter of the intermediate pipe at the neck portion is smaller than the outer diameter of the intermediate pipe at the seal portion. Each seal portion abuts against the inner wall of the circular pipe, and there is a gap for allowing gas to pass between the neck portion and the inner wall of the circular pipe. In the air injection process, the neck portion communicates between the air inlet pipe and the outlet pipe, and the gas passes through the air inlet pipe, the neck portion, and the air outlet pipe in sequence and enters the tire. In the adhesive application process, the neck portion communicates between the air inlet pipe and the storage chamber of the tank, the inner cavity of the intermediate pipe communicates between the storage chamber of the tank and the outlet pipe, the gas passes through the air inlet pipe and the neck portion in sequence and enters the storage chamber, the gas pushes the colloid into the inner cavity of the intermediate pipe, and enters the tire through the outlet pipe.

[0006] The adhesive application device of the present invention includes a tank, a cover, and an intermediate pipe. The tank has a storage chamber for holding a colloid. The cover is assembled to the tank. The cover has a circular pipe, an outlet pipe, and an air inlet pipe. The outlet pipe and the air inlet pipe each extend from the circular pipe and communicate with the circular pipe. The intermediate pipe is movably disposed within the circular pipe, and the circular pipe and the intermediate pipe are coaxially connected to each other. The intermediate pipe has a pair of seal portions and a neck portion located between the seal portions. The outer diameter of the intermediate pipe at the neck portion is smaller than the outer diameter of the intermediate pipe at the seal portion. Each seal portion abuts against the inner wall of the circular pipe, and there is a gap for allowing gas to pass between the neck portion and the inner wall of the circular pipe. When the intermediate pipe moves relative to the circular pipe and the neck portion communicates between the air inlet pipe and the outlet pipe, the adhesive application device is adapted such that a gas is provided to the air inlet pipe by an external component and the gas is discharged from the adhesive application device through the neck portion and the air outlet pipe. When the intermediate pipe moves relative to the circular pipe, the neck portion moves away from the outlet pipe, communicates between the air inlet pipe and the storage chamber of the tank, and the inner cavity of the intermediate pipe communicates between the storage chamber of the tank and the outlet pipe, the adhesive application device is adapted such that a gas is provided to the air inlet pipe by an external component, enters the storage chamber of the tank through the neck portion, and the gas pushes the colloid into the inner cavity of the intermediate pipe and is discharged from the adhesive application device through the outlet pipe.

Advantages of the Invention

[0007] Based on the above, the tire repair device includes both an air supply source and an adhesive application tank. Also, both the air supply source and the adhesive application tank use the cover of the adhesive application tank as a discharge path for gas or colloid. Therefore, the intermediate pipe provided with the adhesive application tank is movably disposed within the circular pipe of the cover of the adhesive application tank, and by moving the intermediate pipe, the cover can be switched to an air injection path or an adhesive application path. Therefore, the present invention can not only perform an independent air injection function on a tire, but also switch to a repair function of applying an adhesive to a damaged tire.

Embodiments for Carrying Out the Invention

[0009] FIG. 1 is a schematic diagram of a tire repair device according to an embodiment of the present invention, which shows an operating state when the tire repair device injects air into or applies an adhesive to a tire 9. FIG. 2 is a three-dimensional schematic diagram of the tire repair device. FIG. 3A is a schematic diagram of some components of the tire repair device in FIG. 2. The box body 1 omits the local structure for the sake of clearly showing the internal air supply source. Referring to FIGS. 1 to 3A, in the present embodiment, the tire repair device includes a box body 1 and an adhesive application device 30. An air supply source, that is, an air compressor 2, is arranged inside the box body 1. The tire repair device further includes a lightweight power plug 15, which can be easily stored on the box body 1 or, when the user wants to start the device, the power plug 15 can be inserted into the power supply to receive power (not shown). On the outer surface of the box body 1, a push-type switch 11, a concave external storage space 12, a concave embedded opening 13, a through hole 14, and a power plug storage slot 150 are provided. The cover 4 of the adhesive application device 30 can be arranged in the embedded opening 13. At the same time, the tank 3 combined with the cover 4 can be stored in the external storage space 12 of the box body 1. The tank 3 is used to store the colloid 34. The tank 3 in the present embodiment is semi-transparent so that the amount of the colloid 34 inside can be easily identified.

[0010] FIG. 3B is a schematic diagram of the other side of the tire repair device in FIG. 2. Referring to FIG. 3B, when the device is not injecting air or the adhesive is not being applied, the adhesive discharge hose 291 connected to the outlet pipe 45 of the adhesive application device 30 can be bent and stored in the inner recess 17 arranged on one side of the box body 1.

[0011] FIG. 4 is an exploded view of the tire repair device of FIG. 2. Referring simultaneously to FIGS. 2, 3A, 3B and FIG. 4, the tire repair device further includes a fixing belt 8 that can surround the outside of the tank 3 of the adhesive application device 30, and the positioning seats 81 at both ends of the fixing belt 8 are fixed to the positioning holes 16 of the box body 1 by using locking members 82, so that the adhesive application device 30 can be stably positioned, and thus is fixed to the box body 1 and can maintain an upright posture without tilting or falling over. FIG. 5 is an exploded view of the adhesive application device. FIG. 6 is a front view of the tire repair device of FIG. 2. Referring simultaneously to FIGS. 4 to 6, the tire repair device further includes an adhesive discharge hose 291, one end of which is connected to the outlet pipe 45 of the adhesive application device 30. As shown in FIG. 1, the other end of the adhesive discharge hose 291 has a connector 290 for connecting to the air nozzle 91 of the tire 9. As shown in FIGS. 3A, 4 and 6, when the switch 11 is activated, the compressed air generated by the air compressor 2 passes through the exhaust manifold 27, the inside of the adhesive application device 30, and the adhesive discharge hose 291 and enters the tire 9, and the functions of repairing and injecting air into the tire 9 can be achieved by an independent air injection function or by applying the colloid 34.

[0012] Furthermore, FIG. 7 is a schematic view of the warning state of the warning mechanism. First, referring to FIGS. 2 to 4, a warning mechanism 292 is arranged in the air compressor 2 of the present invention. Then, referring further to FIGS. 3A and 7, when the compressed air generated by the air compressor 2 reaches the pressure set value, a high-frequency vibration sound is generated, and at the same time, the warning mechanism 292 rises to expose the through hole 14 of the box body 1, so as to warn the user so that the user can operate the air injection of the air compressor 2 more safely and effectively. In one embodiment, a safety valve (not shown) is arranged in the exhaust manifold 28. When the air pressure in the air storage seat 26 is higher than the set pressure of the safety valve, the safety valve opens, and the excess high-pressure air is discharged from the exhaust manifold 28, thereby pushing up the warning mechanism 292. At the same time, when the high-pressure air passes through the safety valve, a high-frequency vibration sound is generated. Thereby, a warning signal can be given to the user visually and auditorily.

[0013] FIG. 8A is a cross-sectional view showing the air injection state of the tire repair device. FIG. 8B is a partially enlarged view of FIG. 8A. FIG. 10A is a cross-sectional view of the tire repair device, which shows the adhesive application state and the warning state. FIG. 10B is a partially enlarged view of FIG. 10A. FIG. 10C is a partial cross-sectional view showing FIG. 10A three-dimensionally.

[0014] First, referring to FIGS. 6, 8A and 10A, the air compressor 2 basically has a main frame 21 and a cylinder 22 coupled to the main frame 21. At the same time, a motor 23 is fixed to the main frame 21, and the motor 23 can rotationally drive a gear 24. The gear 24 simultaneously interlocks a piston body 25 disposed in the cylinder 22. The piston body 25 can reciprocate in the cylinder 22 to generate compressed air. An air reservoir seat 26 communicates with the cylinder 22, and a plurality of exhaust manifolds 27, 28 are disposed on the air reservoir seat 26. Here, the exhaust manifold 27 is exposed at the embedding opening 13 of the box body 1, and the air inlet pipe 44 of the adhesive application device 30 is connected to the exhaust manifold 27 and is quickly coupled and fixed to the embedding plate 271 of the exhaust manifold 27 through the branch structure 46 of the adhesive application device 30. As shown in FIG. 6, by quickly coupling the air inlet pipe 44 of the adhesive application device 30 to the exhaust manifold 27 of the air compressor 2, not only can the connection of the pipeline be reduced and the volume be decreased, but also the adhesive application device 30 can be quickly separated from the air compressor 2 for the convenience of replacing the adhesive application device 30 for tire repair.

[0015] Referring to FIG. 5 simultaneously, the adhesive application device 30 has a tank 3, a cover 4, an intermediate pipe 5, and an external pipe 6. The tank 3 is hollow inside and has an open end 31 and a bottom end 32. The accommodation chamber 33 of the tank 3 may be filled with a colloid 34 for adhesive application (see also FIGS. 8A, 8B, 10A, and 10B). A concave outer ring groove 35 is arranged on the outer peripheral wall of the tank 3. The cover 4 can be coupled to the open end 31 of the tank 3 by screwing, heat fusion, etc. In this embodiment, for example, as shown in FIG. 5, the cover 4 is welded to the open end 31 of the tank 3 by ultrasonic heat fusion.

[0016] The cover 4 of this embodiment has a circular pipe including a lower circular pipe 41 and an upper circular pipe 42 whose upper and lower ends respectively extend and penetrate. In the lower circular pipe 41 and the upper circular pipe 42, a lower flow-through chamber 410 and an upper flow-through chamber 420 that communicate with each other are arranged. In the lower flow-through chamber 410, a minute convex wall 411 that slightly extends toward the inner diameter side is arranged. At the center of the minute convex wall 411, a circular hole 412 (see also FIGS. 8A and 8B) that can communicate with the lower flow-through chamber 410 and the upper flow-through chamber 420 is formed. Using the minute convex wall 411 as a partitioning point, the lower flow-through chamber 410 is partitioned into an upper section and a lower section. The inner pipe diameter ID2 of the lower section of the lower flow-through chamber 410 facing downward is larger than the inner pipe diameters ID1 of the upper section of the lower flow-through chamber 410 facing upward and the upper flow-through chamber 420. That is, the lower section is regarded as the expansion part of the circular pipe, and the upper section is regarded as the contraction part of the circular pipe.

[0017] The upper end of the upper circular pipe 42 is open, and a pair of pivot seats 43 are arranged on the outer peripheral wall of the upper circular pipe 42. Also, an air inlet pipe 44 and an outlet pipe 45 that can communicate with the upper flow-through chamber 420 are arranged in the upper circular pipe 42. A branch structure 46 having a wrench part 461 is arranged in the air inlet pipe 44, a snap block 462 is arranged in the wrench part 461, and the snap block 47 is arranged on the outer peripheral wall of the upper circular pipe 42 in the upper side direction of the outlet pipe 45.

[0018] Furthermore, the structure on the back side of the upper end (closed end) of the intermediate pipe 5 having the inner hollow portion 50, that is, the closed upper end groove 51, is exposed to the outside of the circular pipe, and the tip (open end) of the intermediate pipe 5 presents an open-type opening 52. Also, at least two separated upper annular walls 53, intermediate annular walls 54, and lower annular walls 55 are arranged on the outer periphery of the upper end intermediate pipe 5. Between the upper annular wall 53 and the intermediate annular wall 54, a first neck ring slot 56 with a smaller outer diameter of the pipe body is formed. In the first neck ring slot 56, at least one through hole 560 capable of penetrating the inside and outside of the intermediate pipe 5 is arranged. Between the intermediate annular wall 54 and the lower annular wall 55, a second neck ring slot 57 with a smaller outer diameter of the pipe body is arranged. Sealing rings 530, 540, and 550 are respectively arranged between the two separated upper annular walls 53, intermediate annular walls 54, and lower annular walls 55. The upper annular wall 53 and the sealing ring 530 form a sealing portion, the intermediate annular wall 54 and the sealing ring 540 form a sealing portion, the lower annular wall 55 and the sealing ring 550 form a sealing end. The first neck ring slot 56 located between the two sealing portions (the upper annular wall 53 and the sealing ring 530, the intermediate annular wall 54 and the sealing ring 540) forms a neck portion, and the second neck ring slot 57 located between the two sealing portions (the intermediate annular wall 54 and the sealing ring 540, the lower annular wall 55 and the sealing ring 550) forms a neck portion. Here, the sealing portion means that after the intermediate pipe 5 is incorporated into the circular pipe, a structure capable of blocking the passage of fluid (gas or colloid 34) is formed between the above structure and the inner wall of the circular pipe. The neck portion means that a gap through which fluid can pass is maintained between the above structure and the inner wall of the circular pipe.

[0019] At least one flow slot 58 is arranged on the tube wall at the tip of the intermediate tube 5. The tip of the intermediate tube 5 may enter from the upper circular tube 42 and exit from the lower circular tube 41. At this time, the lower annular wall 55 of the intermediate tube 5 can just abut against the micro convex wall 411 in the cover 4, whereby the upper annular wall 53 and the intermediate annular wall 54 portions of the intermediate tube 5 are accommodated in the upper flow chamber 420 of the upper circular tube 42 of the cover 4, and the lower annular wall 55 portion of the intermediate tube 5 can be accommodated in the upper stage portion of the lower flow chamber 410 of the lower circular tube 41 of the cover 4. At this time, displaceable annular gaps 401, 402 are formed between the first necking slot 56 and the second necking slot 57 and the inner tube walls of the upper circular tube 42 and the lower circular tube 41.

[0020] In this embodiment, the outer tube 6 has a completely penetrated hollow portion 60. The upper end of the outer tube 6 is fitted and fixed to the tip of the lower circular tube 41 of the cover 4. At least one flow groove 61 is arranged on the tube wall at the tip of the outer tube 6. The outer tube 6 covers the outer circumference of the aforementioned intermediate tube 5. As shown in FIG. 5, a driving portion 71 is arranged at one end of the wrench 7, and a pivot portion 72 having a shaft hole 720 is arranged at the other end. An abutting post 73 is arranged between the driving portion 71 and the pivot portion 72, and an end portion 74A is arranged on the abutting post 73. A snap portion 75 is arranged inside the driving portion 71. The wrench 7 can pivot on the pivot seat 43 of the aforementioned upper circular tube 42 through the shaft hole 720 of the pivot portion 72. At the same time, in the state of injecting air without applying an adhesive, as shown in FIGS. 8A and 8B, the end portion 74A of the wrench 7 can be engaged with the snap block 462 of the wrench portion 461 of the branch structure 46 arranged on the air inlet tube 44, and a communication relationship is formed between the air inlet tube 44 and the outlet tube 45 of the adhesive application device 30.

[0021] As shown in FIGS. 5 and 9, in the present embodiment, a plurality of opening grooves 48b are further arranged at the tip of the lower circular pipe 41 away from the upper circular pipe 42, thereby forming a plurality of elastic portions 48a. Correspondingly, a plurality of ridges 62 are further arranged at the connection portion of the external pipe 6 with the lower circular pipe 41. Thereby, the external pipe 6 abuts against the elastic portion 48a via the ridge 62, and the external pipe 6 is fixed to the tip of the lower circular pipe 41, and the coupling of the two is completed. Therefore, when the tire 9 is damaged and operations such as air injection into the tire or adhesive application are required, referring to FIGS. 10A, 10B, and 10C, the user controls the wrench 7 with the shaft hole 720 of the pivot portion 72 as the swing center, and the wrench 7 swings in a substantially semicircular shape, and the snap portion 75 of the wrench 7 engages with the snap block 47 of the upper circular pipe 42 described above. At this time, the other end 74B of the contact post 73 abuts against the closed upper end groove 51 at the upper end of the intermediate pipe 5, and pushes down the intermediate pipe 5. The intermediate annular wall 54 of the intermediate pipe 5 just cuts off the communication relationship between the air inlet pipe 44 and the outlet pipe 45, and the high-pressure air entering the upper circular pipe 42 from the air inlet pipe 44 cannot be directly discharged from the outlet pipe 45. Due to the presence of the opening groove 48b, it moves between the lower flow chamber 410 and the hollow portion 60 of the external pipe 6 described above. The high-pressure air first overflows from the opening groove 48b into the external pipe 6, flows into the storage chamber 33, and further pushes out the colloid 34 in the tank 3. The colloid 34 in the tank 3 enters the inner space 50 of the intermediate pipe 5 through the flow concave groove 61 at the tip of the external pipe 6 and the flow slot 58 at the tip of the intermediate pipe 5, comes to the first necking slot 56, and then flows out from the through hole 560 into the gap 401, and quickly floats until the colloid 34 for adhesive application is discharged along the outlet pipe 45. Thereafter, as shown in FIG. 1, the connector 290 on the adhesive discharge hose 291 exposed outside the box body 1 executes the adhesive application function. Thereby, it is possible to effectively prevent the gas generated in the flow concave groove 61 from being mixed with the colloid 34 during the adhesive application process and affecting the smooth extrusion of the colloid 34.

[0022] Note that the snap blocks 462 and 47 can effectively provide a clear positioning feeling to the user during the process of driving the wrench 7. At the same time, the sound generated by the collision of the structure can also bring an effect of prompting the user's attention. Briefly speaking, by arranging the snap blocks 462 and 47 at the starting point and the ending point of the pivot path of the wrench 7, the operating feeling of the user when driving the wrench 7 is improved.

[0023] The intermediate pipe 5 and the outer pipe 6 are assembled to the cover 4. After the cover 4 is connected to the aforementioned tank 3, most of the lower circular pipe 41 of the cover 4, the outer pipe 6 and the intermediate pipe 5, for example, from the lower annular wall 55 to the tip of the intermediate pipe 5, are all built into the accommodation chamber 33 of the tank 3 as shown in FIGS. 8A and 8B. Also, referring to FIGS. 2 and 4, the aforementioned fixing belt 8 is arranged surrounding the outer ring groove 35 of the tank 3. By fixing the positioning seats 81 at both ends of the fixing belt 8 to the positioning holes 16 of the box body 1 with the locking members 82, the adhesive application device 30 is stably positioned in an upright state without tilting or falling.

[0024] The initial state of the automobile tire repair device of the present invention is as shown in FIGS. 8A and 8B. The initial state is an air injection state, and the intermediate pipe 5 is not forced to move. At this time, the lower annular wall 55 of the intermediate pipe 5 abuts against the micro convex wall 411 of the cover 4, and the lower annular wall 55 of the intermediate pipe 5 is blocked by the circular hole 412 of the micro convex wall 411 of the cover 4. The high-pressure air generated by the air compressor 2 enters the air inlet pipe 44 of the adhesive application device 30 and the upper circular pipe 42 of the cover 4 through the exhaust manifold 27, and flows through the annular gap 402 located in the second neck ring slot 57 of the intermediate pipe 5. A communication relationship is formed between the air inlet pipe 44 and the outlet pipe 45 of the adhesive application device 30, that is, the high-pressure air is directly discharged from the outlet pipe 45 to independently perform the operation of injecting air into the tire 9. When the compressed air generated by the air compressor 2 reaches the pressure setting value, a high-frequency vibration sound is generated. At the same time, as shown in FIG. 7, the alarm mechanism 292 rises to expose the through hole 14 of the box body 1 to warn the user.

[0025] When the tire 9 is damaged and operations such as air injection into the tire or application of an adhesive are required, it can be switched to FIGS. 8A, 8B to FIGS. 10A, 10B and 10C. That is, the wrench 7 is controlled with the shaft hole 720 of the pivot portion 72 as the swing center, and the wrench 7 swings in a substantially semicircular shape, and the snap portion 75 of the wrench 7 engages with the snap block 47 of the upper circular tube 42 described above. At this time, the abutting post 73 abuts against the closed upper end groove 51 at the upper end of the intermediate tube 5 described above, drives the intermediate tube 5 to move downward, and reaches the colloid 34 in the tank 3. The intermediate annular wall 54 of the intermediate tube 5 just cuts off the communication relationship between the air inlet tube 44 and the outlet tube 45. The high-pressure air entering the upper circular tube 42 from the air inlet tube 44 cannot be directly discharged from the outlet tube 45, but passes through the gap 402 between the second neck ring slot 57 and the lower circular tube 41, passes through the circular hole 412 of the micro convex wall 411 in the cover 4, the lower flow chamber 410 of the lower circular tube 41, and the hollow portion 60 of the outer tube 6, and enters the accommodation chamber 33 of the tank 3.

[0026] Subsequently, the high-pressure air entering the accommodation chamber 33 can push out the colloid 34 in the tank 3. The colloid 34 in the tank 3 passes through the flow concave groove 61 at the tip of the outer tube 6 and the flow slot 58 at the tip of the intermediate tube 5, enters the inner cavity 50 of the intermediate tube 5, comes to the first neck ring slot 56, then flows out from the through hole 560 into the gap 401, and quickly floats up until the colloid 34 for adhesive application is discharged along the outlet tube 45. Then, as shown in FIG. 7, the connector 290 on the adhesive discharge hose 291 exposed outside the box body 1 executes the adhesive application function. Here, according to the technology disclosed in FIGS. 8A to 10C, the automobile tire repair device of the present invention can not only independently provide the function of using air injection, but also has the function of performing repair by adhesive application only by operating the wrench 7 when the tire 9 is damaged.

[0027] FIG. 11 is a schematic view of an adhesive application device according to another embodiment of the present invention. FIG. 12 is an exploded view of the adhesive application device of FIG. 11. FIG. 13A is a cross-sectional view of the adhesive application device of FIG. 11. FIG. 13B is a partially enlarged view of FIG. 13A. FIG. 14 is a partial cross-sectional view of the adhesive application device of FIG. 11 in another state. FIG. 15A is a cross-sectional view of the adhesive application device of FIG. 11 in another state. FIG. 15B is a partially enlarged view of FIG. 15A.

[0028] First, referring to FIGS. 11 and 12, in the present embodiment, the adhesive application device 30A can be incorporated into the box body 1 and used as a part of the tire repair device, similar to the above-described adhesive application device 30. The adhesive application device 30A in the present embodiment includes a tank 3A, a cover 4A, and an intermediate pipe 5A. The tank 3A is used to hold the colloid 34 (illustrated in FIGS. 15A and 15B), the cover 4A is assembled to the tank 3A, the cover 4A has a circular pipe 42A, an outlet pipe 45A, and an air inlet pipe 44A, and the outlet pipe 45A and the air inlet pipe 44A each extend from the circular pipe 42A and communicate with the circular pipe 42A. Therefore, for the adhesive application device 30A, it is necessary to connect an external air supply source (not shown. However, the above-described air compressor 2 can be referred to) to the air inlet pipe, provide gas to the air inlet pipe 44A, and execute the above-described air injection or adhesive application technique.

[0029] Referring to FIGS. 12, 13A, and 13B, the intermediate pipe 5A is movably disposed within the circular pipe 42A, and the circular pipe 42A and the intermediate pipe 5A are coaxially connected to each other. The intermediate pipe 5 has a pair of seal portions 54A, 55A and a neck portion 57A located between the pair of seal portions 54A, 55A. The outer diameter of the neck portion 57A of the intermediate pipe 5A is smaller than the outer diameter of the seal portions 54A, 55A of the intermediate pipe 5A. Each of the seal portions 54A, 55A abuts against the inner wall of the circular pipe 42A, and there is a gap 402 for gas to pass through between the neck portion 57A and the inner wall of the circular pipe 42A.

[0030] Unlike the previous embodiment, the cover 4A of this embodiment has a buckle 4A1 and a female screw 4A2 corresponding to the male screw 31A at the open end of the tank 3A. That is, the cover 4A is connected to the tank 3A by screwing, and further engaged with the neck portion at the open end by the buckle 4A1, which can prevent the loosening and dropping of the screw by the cover 4A while ensuring the tight engagement between the screws and the stability between the components.

[0031] Also, the steps from FIGS. 13A, 13B to FIGS. 14 and 15B are the same as the steps of FIGS. 8A, 8B, 10A and 10B in the previous embodiment. That is, the driving part 71 of the wrench 7 is used to receive the force and control of the user, and the wrench 7 is driven to pivot with respect to the cover 4A. As a result, the wrench 7 can be switched from the state where the end 74A is engaged with the snap block 462 to the state where the side edge of the driving part 71 of the wrench 7 is engaged with another snap block 47, and the other end 74B of the abutting column 73 can smoothly push down the closed upper end groove 51 of the intermediate pipe 5A. The movement of the intermediate pipe 5A in the circular pipe 42A is the same as that in the previous embodiment, and the same switching effect is achieved, so it will not be described in detail here.

[0032] FIG. 16 is a schematic view of a tire repair device adopting a horizontal box body in the prior art. Referring to FIGS. 1 and 16 simultaneously, as shown in FIG. 16, with the horizontal box body 1A, an air compressor (not shown) and an adhesive injection tank (not shown) are closer to the ground (compared to the vertical box body shown in FIG. 1). In contrast, for the vertical box body 1 shown in FIG. 1, the components of the air compressor can be positioned higher relative to the ground. Therefore, even when facing operating environments such as rainy days or when water splashes on the road, the components can be prevented from being immersed in water, and the risk of metal corrosion due to moisture can be avoided. Further, since the adhesive discharge hose 291A shown in FIG. 16 creates a clear distance between the horizontal box body 1A and the tire 9, the designer needs to increase the length of the adhesive discharge hose 291A. In contrast, in the present invention, as shown in FIG. 1, by adopting the vertical box body 1, the difference in distance between the box body 1 and the tire 9 can be effectively reduced, the required length of the adhesive discharge hose 291 can be reduced, thereby reducing the manufacturing cost and improving the operational convenience.

[0033] In summary, in the above-described embodiment of the present invention, since the intermediate pipe can move within the circular pipe, due to the airtightness of the seal part and the neck part, and the adjustment of the inner and outer diameters of the intermediate pipe and the circular pipe, during the movement process of the intermediate pipe, the switching of the fluid transfer path is performed. Therefore, the tire repair device can satisfy the adhesive application function that the adhesive application tank should have, and can also realize the additional function of injecting air into the tire, providing various function options for the convenience of the user in operation, and meeting the needs of tire repair technology.

Industrial Applicability

[0034] The adhesive application device and the tire repair device of the present invention can be used in vehicle technology, particularly for tire air injection or adhesive application.
