[0001] This application relates to the technical field of vehicle repair, and in particular to a tool for removing and installing tires. Background Technology

[0002] If a tire shows cuts, cracks, bulges, or signs of being run over on the sidewall, it indicates that the internal ply layer may be broken, posing a risk of a blowout, and the tire should be replaced immediately.

[0003] Currently, when changing tires, align the steel pipe with the inner sidewall of the tire (near the rim) and strike it horizontally 3-5 times to separate the tire from the rim through vibration.

[0004] When striking a tire with a steel pipe, the pipe may fly out of the hand, posing a significant safety hazard as it could injure other people. Utility Model Content

[0005] To reduce safety hazards, this application provides a tool for removing and installing tires.

[0006] This application provides a tool for disassembling and assembling tires, which adopts the following technical solution: A tool for removing and installing tires includes a shovel, a roller, and an operating frame, wherein the shovel is disposed on the operating frame and the roller is disposed on the shovel.

[0007] By adopting the above technical solution, the operator moves the operating frame so that the shovel plate extends under the tire; then the operator holds the operating frame with one hand and shakes the operating frame, which drives the shovel plate to move, and the shovel plate drives the tire to move; the operator holds the tire with the other hand and shakes the tire, which causes the tire to shake relative to the rim, and then the tire is separated from the rim; therefore, the tire removal tool can reduce safety hazards.

[0008] Optionally, the operating frame includes a support rod, a first connecting rod, a second connecting rod, a third connecting rod, and a handle rod. The shovel plate is mounted on the support rod, and the rolling wheel is mounted on the support rod. The first connecting rod is mounted on the support rod, the second connecting rod is mounted on the first connecting rod, the third connecting rod is mounted on the second connecting rod, and the handle rod is mounted on the third connecting rod.

[0009] By adopting the above technical solution, the operator holds the handle and shakes it, which drives the third link to move. The second link on the third link drives the first link to move, the first link drives the support rod to move, and the support rod drives the shovel plate to move.

[0010] Optionally, the third link includes a fixed rod, an adjusting rod, and a fixing assembly. The fixed rod is disposed on the second link, the adjusting rod is disposed on the fixed rod via the fixing assembly, and the handle is disposed on the adjusting rod.

[0011] By adopting the above technical solution, since operators have different heights and operating habits, the adjusting rod can be made to move relative to the fixed rod according to actual needs. After the adjusting rod drives the handle to a suitable position, the adjusting rod is fixed to the fixed rod with a fixing component, so that the handle will be in the appropriate position. The variable length third link can improve applicability.

[0012] Optionally, the fixing assembly includes a fixing bolt and a fixing nut. The fixing rod has a first groove, and the adjusting rod is slidably disposed in the first groove. The fixing rod has a first through hole communicating with the first groove, and the adjusting rod has a second through hole. The fixing bolt passes through the first through hole on the fixing rod and the second through hole on the adjusting rod. The fixing nut is threadedly connected to the fixing bolt. The nut of the fixing bolt and the fixing nut are respectively located on both sides of the fixing rod.

[0013] By adopting the above technical solution, once the position of the adjusting rod is determined, the end of the fixing bolt away from the nut passes through the first groove on the fixing rod and the second through hole on the adjusting rod; then the fixing nut is threaded to the fixing bolt, and both the nut of the fixing bolt and the fixing nut are pressed against the fixing rod, thereby stably fixing the adjusting rod to the fixing rod; the fixed component structure is simple and easy to operate.

[0014] Optionally, the fixing rod has a third through hole communicating with the first groove, and the fixing rod is provided with a positioning mechanism, the positioning mechanism including a support block, a positioning block and a spring, the support block is disposed on the fixing rod, the positioning block is slidably disposed on the support block, one end of the spring is connected to the positioning block and the other end is connected to the support block; the adjusting rod has a sliding groove that slides with the positioning block, the adjusting rod has a positioning groove communicating with the sliding groove, and the positioning block can engage with the positioning groove.

[0015] By adopting the above technical solution, the support block is connected to the fixed rod, and one end of the positioning block passes through the third through hole and is located in the groove of the adjusting rod. When the adjusting rod slides in the first groove of the fixed rod, the positioning block slides in the groove. The groove limits the path of the positioning block, reducing the phenomenon of the adjusting rod rotating relative to the fixed rod, thus facilitating the subsequent installation of the fixing bolts and fixing nuts. Moreover, when the positioning block enters the positioning groove of the adjusting rod, the first through hole on the fixed rod aligns with the second through hole on the adjusting rod, realizing the rapid installation of the fixing bolts and fixing nuts. Therefore, the positioning mechanism facilitates the subsequent installation of fixing bolts and fixing nuts when adjusting the position of the adjusting rod, thereby improving efficiency.

[0016] Optionally, the support block includes a first connecting block, a second connecting block, a third connecting block, and a connecting bolt. The first connecting block and the second connecting block abut against the fixing rod. The first connecting block has a fourth through hole, and the second connecting block has a first threaded hole. The connecting bolt passes through the fourth through hole and is threadedly connected to the first threaded hole. The third connecting block is disposed on the second connecting block, and the positioning block is slidably disposed on the third connecting block.

[0017] By adopting the above technical solution, the positioning block on the third connecting block is extended into the third through hole of the fixing rod, and the second connecting block abuts against the fixing rod; then the first connecting block abuts against the fixing rod, and finally the connecting bolt passes through the fourth through hole and is threadedly connected to the first threaded hole.

[0018] Optionally, the first connecting rod is provided with a reinforcement mechanism connected to the second connecting rod. The reinforcement mechanism includes a first reinforcement block, a second reinforcement block, and an assembly component. One end of the first reinforcement block abuts against the first connecting rod and the other end abuts against the second connecting rod. One end of the second reinforcement block abuts against the first connecting rod and the other end abuts against the second connecting rod. The second reinforcement block abuts against the first reinforcement block, and a reinforcement cavity is formed between the first reinforcement block and the second reinforcement block. The connection point between the first connecting rod and the second connecting rod is located within the reinforcement cavity. The assembly component is disposed on the second reinforcement block and connected to the first reinforcement block.

[0019] By adopting the above technical solution, the first reinforcing block abuts against the first and second connecting rods, and the second reinforcing block abuts against the first and second connecting rods. Then, the first and second reinforcing blocks are connected together by an assembly component, so that the connection position of the first and second connecting rods is located within the reinforcing cavity of the first and second reinforcing blocks, thereby reducing the phenomenon of relative bending between the first and second connecting rods.

[0020] Optionally, the assembly component includes a locking block and an assembly bolt. The locking block is disposed on the second reinforcing block, and the first reinforcing block has a locking groove for engaging with the locking block. The second reinforcing block has a fifth through hole, and the first reinforcing block has a second threaded hole. The assembly bolt passes through the fifth through hole and is threadedly connected to the second threaded hole.

[0021] By adopting the above technical solution, the card block is connected to the slot on the first reinforcing block, and then the assembly bolt is threaded through the fifth through hole and connected to the second threaded hole, so that the first reinforcing block and the second reinforcing block are connected together.

[0032] A first stabilizing rod 81 is welded to the first connecting rod 32, and the end of the first stabilizing rod 81 away from the first connecting rod 32 is welded to the second connecting rod 33; a second stabilizing rod 82 is welded to the second connecting rod 33, and the end of the second stabilizing rod 82 away from the second connecting rod 33 is welded to the third connecting rod 4.

[0033] The implementation principle of Embodiment 1 of this application is as follows: the operator holds the handle 34 and pushes the handle 34 to move, the handle 34 drives the third link 4 to move, the third link 4 drives the second link 33 to move, the second link 33 drives the first link 32 to move, the first link 32 drives the support rod 31 to move, and the roller 2 on the support rod 31 will move on the ground. When the roller 2 moves, the base plate 11 will not touch the ground.

[0034] Use a jack or other lifting structure to lift the tire off the ground at a certain distance, and then extend the base plate 11 under the tire.

[0035] Then, the operator holds the handle 34 with one hand and shakes the handle 34. The handle 34 drives the base plate 11 and the vertical rod to move through the third link 4, the second link 33, the first link 32 and the support rod 31. The shovel plate 1 composed of the base plate 11 and the vertical plate 12 drives the tire to move. The operator holds the upper end of the tire with the other hand and shakes the tire, so that the tire shakes relative to the wheel hub, and then the tire separates from the wheel hub.

[0036] Example 2 refer to Figure 3 and Figure 4 The difference from Embodiment 1 is that the third link 4 includes a fixed rod 41 integrally formed with the second link 33. The fixed rod 41 has a first groove at the end away from the second link 33. An adjusting rod 42 is slidably connected in the first groove. The handle 34 is fixedly connected to the end of the adjusting rod 42 away from the second link 33.

[0037] The fixing rod 41 has a first through hole communicating with the first groove, and the adjusting rod 42 has multiple second through holes 421 along its length. The fixing rod 41 is provided with a fixing assembly 43, which includes a fixing bolt 431. The end of the fixing bolt 431 away from its own nut passes through the first through hole on the fixing rod 41 and the second through hole 421 on the adjusting rod 42. A fixing nut 432 is threaded onto the fixing bolt 431, and both the fixing nut 432 and the nut of the fixing bolt 431 abut against the side wall of the fixing rod 41.

[0038] According to the operator's height or operating habits, the adjusting rod 42 slides in the first groove of the fixed rod 41, and the adjusting rod 42 will drive the handle 34 to move. After the position of the handle 34 is determined, the end of the fixing bolt 431 away from its own nut passes through the first through hole on the fixed rod 41 and the second through hole 421 on the adjusting rod 42. Then, the fixing nut 432 is threadedly connected to the fixing bolt 431, and the nut of the fixing bolt 431 and the fixing nut 432 are both pressed against the side wall of the fixed rod 41 to fix the position of the adjusting rod 42 and the handle 34.

[0039] refer to Figure 4 and Figure 5 A positioning mechanism 5 is provided on the fixing rod 41. The positioning mechanism 5 includes a support block 6, which includes a first connecting block 61 and a second connecting block 62. Both the first connecting block 61 and the second connecting block 62 abut against the fixing rod 41. The first connecting block 61 has a fourth through hole, and the second connecting block 62 has a first threaded hole. A connecting bolt 64 is provided on the first connecting block 61. The connecting bolt 64 passes through the fourth through hole on the first connecting block 61 and is threadedly connected to the first threaded hole on the second connecting block 62. The second connecting block 62 has a second groove 621, and a third connecting block 63 is engaged in the second groove 621.

[0040] refer to Figure 5 and Figure 6 The second connecting block 62 has a cavity communicating with the second groove 621. An assembly mechanism 9 is provided on the second connecting block 62. The assembly mechanism 9 includes an assembly block 91 slidably connected to the cavity. A third connecting block 63 located within the second groove 621 has an assembly groove 631 that engages with the assembly block 91. A rack 92 is integrally provided on the assembly block 91. A rotating shaft 93 is rotatably connected to the second connecting block 62, and a gear 94 that meshes with the rack 92 is keyed to the rotating shaft 93.

[0041] refer to Figure 4 and Figure 5 The fixing rod 41 has a third through hole that communicates with the first groove, and the axis of the third through hole is perpendicular to the axis of the first through hole; the adjusting rod 42 has a sliding groove 422 and a positioning groove 423 that communicates with the sliding groove 422 along its length; the third connecting block 63 has a sixth through hole.

[0042] A positioning block 51 is slidably connected to the sixth through hole of the third connecting block 63. One end of the positioning block 51 can pass through the third through hole of the fixing rod 41 and enter the sliding groove 422 of the adjusting rod 42, and the positioning groove 423 on the adjusting rod 42 can engage with the positioning block 51. When the positioning block 51 engages with the positioning groove 423 on the adjusting rod 42, the axis of one of the second through holes 421 on the adjusting rod 42 coincides with the axis of the first through hole on the fixing rod 41. A spring 52 is connected to the positioning block 51, and the end of the spring 52 away from the positioning block 51 engages with the third connecting block 63.

[0043] First, one end of the positioning block 51 passes through the third through hole on the fixing rod 41 and enters the sliding groove 422 of the adjusting rod 42. Then, the position of the second connecting block 62 is adjusted so that the third connecting block 63 enters the second groove 621 of the second connecting block 62. Next, the rotating shaft 93 is rotated, which drives the gear 94 to rotate. The gear 94 drives the rack 92 to move, and the rack 92 drives the assembly block 91 to move, so that the assembly block 91 engages with the assembly groove 631 on the third connecting block 63. Then, the position of the first connecting block 61 is adjusted so that one end of the first connecting block 61 abuts against the second connecting block 62, and the fixing rod 41 is located between the first connecting block 61 and the second connecting block 62. Both the first connecting block 61 and the second connecting block 62 abut against the side wall of the fixing rod 41. Finally, the connecting bolt 64 passes through the fourth through hole on the first connecting block 61 and is threaded into the first threaded hole on the second connecting block 62, thereby connecting the support block 6 to the fixing rod 41.

[0044] When the adjusting rod 42 slides within the first groove of the fixed rod 41, the positioning block 51 slides within the sliding groove 422 of the adjusting block. The positioning block 51 limits the movement path of the adjusting block, and the spring 52 is in a compressed state at this time. When the positioning block 51 aligns with the positioning groove 423, the force of the spring 52 restoring its elastic deformation drives the positioning block 51 to move, causing the positioning block 51 to engage with the positioning groove 423. At this time, the axis of the first through hole on the fixed rod 41 coincides with the axis of the second through hole 421 on the adjusting rod 42, which facilitates the subsequent installation of the fixing bolt 431.

[0045] refer to Figure 3 and Figure 7A reinforcing mechanism 7 is provided at the connection position of the first connecting rod 32 and the second connecting rod 33. The reinforcing mechanism 7 includes a first reinforcing block 71 and a second reinforcing block 72. Both the first reinforcing block 71 and the second reinforcing block 72 are arc-shaped. One end of the first reinforcing block 71 abuts against the first connecting rod 32 and the other end abuts against the second connecting rod 33. One end of the second reinforcing block 72 abuts against the first connecting rod 32 and the other end abuts against the second connecting rod 33. An assembly component 73 is provided on the second reinforcing block 72. The assembly component 73 includes a locking block 731 fixedly connected to the second reinforcing block 72. The first reinforcing block 71 has a locking groove 711 that engages with the locking block 731. The second reinforcing block 72 has a fifth through hole and a second threaded hole. An assembly bolt 732 is provided on the second reinforcing block 72. The assembly bolt 732 passes through the fifth through hole on the second reinforcing block 72 and is threadedly connected to the second threaded hole on the first reinforcing block 71.

[0046] The same reinforcing mechanism 7 is also provided at the connection position of the third link 4 and the second link 33. In the reinforcing mechanism 7, one end of the first reinforcing block 71 abuts against the third link 4 and the other end abuts against the second link 33, and one end of the second reinforcing block 72 abuts against the third link 4 and the other end abuts against the second link 33.

[0047] The same reinforcing mechanism 7 is also provided at the connection position of the third link 4 and the handle bar 34. In the reinforcing mechanism 7, one end of the first reinforcing block 71 abuts against the third link 4 and the other end abuts against the handle bar 34, and one end of the second reinforcing block 72 abuts against the third link 4 and the other end abuts against the handle bar 34.

[0048] The implementation principle of Embodiment 2 of this application is as follows: The position of the adjusting rod 42 relative to the fixed rod 41 is adjusted according to the operator's height and operating habits. The adjusting rod 42 then drives the handle rod 34 to move to a suitable position. After the position of the handle rod 34 is determined, the fixing bolt 431 and the fixing nut 432 are installed onto the fixed rod 41.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
