[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 3 As shown, an embodiment of the utility model provides a disassembly tool, which includes: a cylinder 10, a sliding part 20 and a reset part 30. The cylinder 10 has a first end 11 and a second end 12 that are arranged opposite to each other, the first end 11 is used to connect with the locking ring block on the tire, and the cylinder 10 has a receiving cavity 13. The sliding part 20 is at least partially movably arranged in the receiving cavity 13, and the sliding part 20 can impact the second end 12 to pull out the locking ring block on the tire by inertia. The reset part 30 is arranged at the second end 12, and the reset part 30 can drive the sliding part 20 to move from the second end 12 to the first end 11.

[0036] By applying the technical solution of the utility model, the first end 11 of the cylinder 10 is connected to the locking ring block on the tire, and the cylinder 10 has a receiving cavity 13, in which a sliding part 20 is arranged, so that the sliding part 20 can impact the second end 12 of the cylinder 10, so that the second end 12 of the cylinder 10 generates an inertial force in the direction away from the locking ring block on the tire, and then the cylinder 10 can be driven to move in the direction away from the locking ring block on the tire, and finally the locking ring block is pulled out from the tire. At the same time, the reset part 30 can also drive the sliding part 20 to move in the direction of the first end 11 after impacting the second end 12 of the cylinder 10, so as to reset the position of the sliding part 20, so as to facilitate the sliding part 20 to impact the second end 12 of the cylinder 10 again next time. Through the last setting, the cylinder 10 can guide the sliding part 20 while preventing the sliding part 20 from causing harm to the operator when it breaks due to excessive impact force. At the same time, the reset part 30 can automatically reset the sliding part 20 without manual reset, thereby simplifying the disassembly process, improving the disassembly efficiency, and improving the safety when disassembling the shrink ring block.

[0037] Furthermore, the disassembly tool further includes a driving part, which is drivingly connected to the sliding part 20, and the driving part can drive the sliding part 20 to move in the accommodating chamber 13. Through the above arrangement, compared with manually driving the sliding part 20 to impact the second end 12 of the cylinder 10, the driving part can further reduce the work intensity of the staff, and the driving part can more accurately control the impact force and impact time, and can also avoid the damage to the operator when the sliding part 20 breaks. In this embodiment, the driving part can be set to a driving mode such as motor drive, hydraulic drive, etc.

[0038] There is a gap between the side wall of the sliding part 20 and the side wall of the accommodating chamber 13, the first end 11 has a gas inlet 111, the second end 12 has a gas outlet 121, and the driving part is a gas supply device, which is used to supply gas into the accommodating chamber 13 to drive the sliding part 20 to move toward the second end 12. Through the above arrangement, the friction between the sliding part 20 and the side wall of the accommodating chamber 13 can be reduced, so that the sliding part 20 can move more smoothly inside the accommodating chamber 13 to ensure the moving speed of the sliding part 20 in the accommodating chamber 13. At the same time, it can reduce the energy loss of the sliding part 20 when moving, avoid the insufficient impact force of the sliding part 20 on the second end 12 of the cylinder 10, resulting in the inability to quickly press the lock ring on the tire, reduce the number of impacts of the sliding part 20 on the second end 12, and improve the disassembly efficiency of the disassembly tool.

[0039] At the same time, the gap between the side wall of the sliding part 20 and the side wall of the accommodating chamber 13 can also be used for the gas provided by the driving part to flow, so as to prevent the sliding part 20 from being moved from the second end of the cylinder 10 to the first end 11 by the gas, and from being unable to return from the first end 11 to the second end 12 due to the high gas pressure in the accommodating chamber 13. The gas then flows out from the gas outlet 121 to ensure the gas pressure balance inside the accommodating chamber 13, and to avoid explosion caused by excessive gas pressure.

[0040] In the present application, the cylinder 10 is also provided with an air pipe joint at the gas inlet 111, which is threadedly connected to the cylinder 10, and the air pipe joint is connected to the A port of the two-position three-way solenoid valve through the air pipe, and the P port of the two-position three-way solenoid valve is connected to the gas storage tank of the air compression station through the air pipe, and is connected to the high-pressure gas. When in use, press the debugging button to connect the A port with the P port, and the high-pressure gas quickly enters the cylinder 10 from the air pipe joint. The high-pressure gas pushes the sliding part 20 to move quickly toward the second end 12. When it hits the second end 12, the entire device forms a disassembly impact force in the direction away from the lock ring block. The lock ring block can be removed from the tire by multiple high-pressure gas injections. The operation is convenient and reliable, and it greatly saves manpower.

[0041] In the present application, the reset part 30 includes an elastic member, which is arranged on the second end 12, and at least part of the elastic member is located in the accommodating cavity 13. The elastic member can provide buffering for the sliding part 20 and drive the sliding part 20 to move toward the first end 11. Through the above arrangement, when the sliding part 20 impacts the elastic member, part of the kinetic energy of the sliding part 20 can be converted into the elastic potential energy of the elastic member. This part of the elastic potential energy can act on the sliding part 20 after the driving part stops supplying air, so that the sliding part 20 can move from the second end 12 of the cylinder 10 to the first end 11. In this way, the sliding part 20 can quickly reset to prepare for the next impact, thereby improving the disassembly efficiency.

[0042] Specifically, the second end 12 has an opening, which is communicated with the accommodating chamber 13. The disassembly tool also includes an end cap 40, which is detachably connected to the second end 12 and used to seal the opening. The gas outlet 121 is provided on the end cap 40, and the reset portion 30 is connected to the end cap 40. The gas outlet 121, the reset portion 30 and the end cap 40 are all integrated on the second end 12 of the cylinder 10. Such an arrangement reduces the space occupied by the above components, improves the space utilization rate of the device, and can make the device as a whole miniaturized, more lightweight, and easy to use and move.

[0043] like Figure 4 As shown, the end cover 40 has a first hole section 41 and a second hole section 42 connected in sequence, the diameter of the first hole section 41 is larger than the diameter of the second hole section 42, the first hole section 41 is arranged close to the first end 11, the first hole section 41 is threadedly connected to the second end 12, one end of the elastic member is connected to the second hole section 42, the other end of the elastic member is used to abut against the sliding part 20, and the gas outlet 121 is arranged on the end surface of the end cover 40 and communicated with the second hole section 42. Through the above arrangement, the elastic member is arranged in the end cover 40, which further improves the integration of the component and reduces the space occupied. At the same time, by fixing the elastic member on the second end 12 and the first hole section 41 being threadedly connected to the second end, such a design improves the rationality of the device, and the threaded connection method has a simple structure, which facilitates the installation and disassembly of the end cover 40 and the second end 12 of the cylinder.

[0044] In addition, in the above-mentioned design, an elastic member is arranged in the end cover 40, so that when the shrink ring block on the tire is disassembled, when the sliding part 20 is driven by the driving part to move toward the second end 12 of the cylinder 10, the sliding part 20 will directly impact the elastic member first, and most of the kinetic energy will directly act on the end cover 40 through the elastic member to impact the end cover 40, thereby enabling the entire disassembly tool to move in the direction away from the shrink ring block, thereby driving the first end 11 of the cylinder to pull and disassemble the shrink ring block.

[0045] In this embodiment, the gas outlet 121 is provided in multiple forms and is evenly distributed in a ring shape on the upper end of the end cover 40, so that the gas can be evenly discharged from the multiple gas outlets without affecting the structural strength of the end cover 40. In other embodiments of the present application, the gas outlet 121 can also be provided in a single mesh structure, or other structures such as a circular, n-gonal, or irregular shape.

[0046] like Figure 5 As shown, the disassembly tool also includes a connecting rod 50, which is detachably connected to the first end 11, and the extending direction of the connecting rod 50 is the same as the moving direction of the sliding part 20, and the first end 11 is connected to the locking ring block through the connecting rod 50. In this way, the connecting rod 50 is detachably connected to the cylinder 10, and connecting rods 50 of different sizes can be replaced for different types of locking ring blocks, so that the disassembly tool of the present application can be used for tires or locking ring blocks of various sizes. In addition, the above-mentioned arrangement can not only improve the convenience of installation and disassembly of the connecting rod 50, but also when the connecting rod 50 is damaged, it is only necessary to replace the connecting rod 50 alone, without replacing the entire cylinder 10, thereby reducing the maintenance cost of the device.

[0047] The connecting rod 50 includes a connecting column 51 and a mounting plate 52, wherein the mounting plate 52 is used to connect with the first end 11 of the cylinder 10, and the mounting plate 52 is arranged at one end of the connecting column 51, and the connecting column 51 is used to connect with the locking ring block. Through the above arrangement, the mounting plate 52 can increase the connection area between the connecting rod 50 and the second end 12 of the cylinder 10, so that the connection between the connecting rod 50 and the cylinder 10 is more stable and reliable, ensuring that the connecting rod 50 can smoothly remove the locking ring block on the tire.

[0048] Specifically, in the present embodiment, one end of the connecting column 51 connected to the shrinking ring block is processed with an external thread corresponding to the threaded hole on the shrinking ring block, so that the connecting column 51 and the shrinking ring block are connected through a threaded structure, and there is no need to add an additional fixing device to fix the connection between the connecting column 51 and the shrinking ring block, thereby saving the manufacturing and maintenance costs of the device, and the structure is simple and easy to process.

[0049] In the present application, the first end 11 of the cylinder 10 is provided with a mounting groove 112, and the disassembly tool further comprises a gland 60, the mounting groove 112 is threadedly connected with the gland 60, the mounting plate 52 is located in the mounting groove 112, the gland 60 cooperates with the first end 11 to fix the mounting plate 52 in the mounting groove 112, and the connecting column 51 is penetrated on the gland 60. Through the above arrangement, the mounting plate 52 is placed in the mounting groove 112 and then cooperates with the gland 60, so that the position of the mounting plate 52 in the mounting groove 112 can be fixed, and the mounting plate 52 is prevented from excessive displacement and shaking in the circumferential direction when the locking ring block is disassembled, and even falls off from the first end 11 of the cylinder 10, so as to ensure that the device can quickly disassemble the shrinking ring block, and the gland 60 is threadedly connected with the mounting groove 112, so that the gland 60 and the mounting groove 112 are convenient for installation and removal, and when the connecting rod 50 is damaged, it is convenient to replace the connecting rod 50. In other embodiments of the present application, the mounting groove 112 and the pressure cover 60 may also be detachably connected by other connection methods such as snap fit, interference fit, etc.

[0050] Specifically, a gasket 70 is further provided between the mounting plate 52 and the gland 60 to ensure the tightness of the assembly between the gland 60 and the mounting groove 112 .

[0051] like Figure 6 As shown, the cross-sectional areas of the two ends of the sliding part 20 gradually decrease in the direction away from the middle of the sliding part 20. Through the above arrangement, it is possible to effectively prevent the sliding part 20 from getting stuck when impacting the reset part 30 or returning to the first end 11 of the cylinder 10, thereby improving the smoothness of the movement of the sliding part 20 in the accommodating chamber 13.

[0052] In this embodiment, the sliding part 20 includes a slider 21, and the slider 21 is provided with protrusions 22 on both sides facing the first end 11 and the second end 12, respectively. The slider 21 is a cylindrical structure, so that the slider 21 can move linearly along the inner wall of the accommodating cavity 13 to avoid the slider 21 from generating unnecessary energy loss. The protrusion 22 is a conical structure, and a step surface is provided at the connection between the protrusion 22 and the slider 21 for resisting force with the elastic member. In other embodiments of the present application, the specific shapes of the slider 21 and the protrusion 22 are not limited, and it is sufficient to ensure that the sliding part 20 can move in the accommodating cavity 13.

[0053] like Figure 4 and Figure 5 As shown, the outer periphery of the connecting column 51 and the end cover 40 are respectively provided with a plurality of first notches 511 and a plurality of second notches 401. Through the above arrangement, when the connecting rod 50 and the end cover 40 are installed, the friction between them and the tooling can be increased, thereby improving the convenience of device assembly.

[0054] Furthermore, a handle is provided on the peripheral side of the cylinder 10 to facilitate the staff to hold it, and the handle is wrapped with a sponge layer to cushion the impact of the cylinder 10.
