The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Example:

[0030] like Figure 1-3 As shown, this embodiment provides a tool for disassembling and assembling bolts on the return oil pipe of the main air compressor of a high-speed train, including a tool handle 1, a first disassembly and assembly part, a second disassembly and assembly part 19 and a telescopic adjustment part. The first disassembly and assembly part is located at one end of the tool handle 1, and the other end of the tool handle 1 is provided with a bending part 17. The telescopic adjustment part is located at the bending part 17, and the adjustment end of the telescopic adjustment part is connected to the second disassembly and assembly part.

[0031] The first disassembly and assembly section includes several first disassembly and assembly sub-sections, one of which is connected to one end of the tool handle section 1, and the other first disassembly and assembly sub-sections are rotatably engaged with one end of the tool handle section 1. The other first disassembly and assembly sub-sections are provided with fixing members that can be connected to one end of the tool handle section 1.

[0032] The tool for disassembling and assembling the return oil pipe bolt of the main air compressor of the EMU in this embodiment has a first disassembly and assembly part and a second disassembly and assembly part at both ends of the tool handle part 1. The first disassembly and assembly part includes multiple first disassembly and assembly sub-parts. The disassembly and assembly opening on each first disassembly and assembly sub-part can be of different models, so as to adapt to different models of road heavy-duty replacement parts. At the same time, the second disassembly and assembly part can be adjusted relative to the tool handle part 1 through the bending part 17 and the telescopic adjustment part, which can facilitate operation and use in a limited space. When used with the return oil pipe bolt, it can ensure that the main air compressor return oil pipe bolt is not tightened properly due to improper use of tools or mismatch of tool model and size when repairing the main air compressor return oil pipe. This disassembly and assembly tool improves efficiency and saves maintenance and labor costs compared with the original method.

[0033] See Figure 3The specific structure of the telescopic adjustment part in this embodiment is as follows:

[0034] The telescopic adjustment part includes a telescopic adjustment sleeve 2 and an adjustment slider 3. The telescopic adjustment sleeve 2 has a through cavity 4 and a fixing hole 5 communicating with the through cavity 4. The adjustment slider 3 slides in cooperation with the fixing hole 5. The adjustment slider 3 and the fixing hole 5 form the adjustment end of the telescopic adjustment part.

[0035] One end of the bent part 17 is engaged with the through cavity 4, and one end of the bent part 17 is provided with an adjustment groove 6. One end of the second disassembly part is located in the through cavity 4 and the adjustment groove 6. The second disassembly part is provided with an elastic element 7 and a fastener 8. One end of the fastener 8 is connected to the elastic element 7.

[0036] When the elastic element 7 is in the first compressed state and the buckle 8 is inserted into the fixing hole 5, one end of the second disassembly part is connected to the telescopic adjustment sleeve 2 in a fixed state.

[0037] When the elastic element 7 is in the second compression state and the adjusting slider 3 acts to separate the buckle 8 from the fixing hole 5, the connection and fixing state between one end of the second disassembly part and the telescopic adjusting sleeve 2 is released.

[0038] Specifically, the cross-section of the fastener 8 is circular, the longitudinal cross-section of the fastener 8 is T-shaped, the large end face of the fastener 8 is connected to the elastic element 7, and the small end face of the fastener 8 is set towards the fixing hole 5.

[0039] The cross-sectional dimension of the large end face of the fastener 8 is larger than the diameter of the fixing hole 5, and the cross-sectional dimension of the small end face of the fastener 8 is smaller than the diameter of the fixing hole 5.

[0040] Specifically, the second disassembly section has several placement slots 9 for placing the elastic element 7 along its length.

[0041] According to the above structure, since the large end face of the buckle 8 is connected to the elastic member 7 and the small end face of the buckle 8 is set towards the fixing hole 5, the small end face of the buckle 8 cooperates with the fixing hole 5. When the large end face of the buckle 8 blocks the fixing hole 5, the elastic member 7 is in the first compression state. Therefore, one end of the second disassembly part is connected to the telescopic adjustment sleeve 2 in a fixed state.

[0042] At the same time, when the operator separates the small end face of the buckle 8 from the fixing hole 5 by adjusting the slider 3, the elastic element 7 is in the second compression state, which can release the connection and fixing state between one end of the second disassembly part and the telescopic adjustment sleeve 2, thereby adjusting the relative position of one end of the second disassembly part in the telescopic adjustment sleeve 2, and realizing the adjustment of the relative position between the second disassembly part and the tool handle part 1.

[0043] In this embodiment, the first disassembly and assembly sub-parts are a first upper disassembly and assembly sub-part 10, a first middle disassembly and assembly sub-part 11, and a first lower disassembly and assembly sub-part 12. The first middle disassembly and assembly sub-part 11 is connected to one end of the tool handle part 1. The first upper disassembly and assembly sub-part 10 is provided with a rotating shaft 13. One end of the rotating shaft 13 passes through the first middle disassembly and assembly sub-part 11 and the first lower disassembly and assembly sub-part 12. A threaded part is provided at one end of the rotating shaft 13, and a nut is provided on the threaded part.

[0044] Specifically, the first upper disassembly sub-section 10, the first middle disassembly sub-section 11, and the first lower disassembly sub-section 12 are provided with open end sections 14.

[0045] The aforementioned open end 14 can be of different models and sizes on different disassembly and assembly parts according to the usage scenario, so as to facilitate the disassembly and assembly of other bolts of various models during maintenance.

[0046] See Figure 1 and Figure 2 When in use, the first upper disassembly sub-part 10 and the first lower disassembly sub-part 12 can be rotated relative to the first middle disassembly sub-part 11 and then fixed with nuts. After use, the first upper disassembly sub-part 10 and the first lower disassembly sub-part 12 can be rotated relative to the first middle disassembly sub-part 11 and stacked.

[0047] In this embodiment, the other end of the second disassembly / assembly part is provided with a spline head opening 15, and one end of the spline head opening 15 is provided with a notch 16, which facilitates a more secure insertion of the return oil pipe bolt during disassembly / assembly.

[0048] Specifically, the second disassembly / assembly section is L-shaped.

[0049] Specifically, the tool handle 1 is provided with a reading area 18 for recording the tool specifications and model number. The specifications and model number are engraved on the surface of the area, so that the specifications and model number of the tool can be accurately and intuitively understood.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
