Description

TECHNICAL FIELD

[0001] The utility model relates to tool technical field especially relates to a dismounting tool. BACKGROUND

[0002] When the periodic maintenance or troubleshooting of the aircraft is carried out, the aircraft needs to be lifted to a certain height by using the jack. The jack is provided with a round nut and a piston rod. During work, the round nut needs to be rotated and screwed out of the pushing range of the piston rod. After the piston rod drives the aircraft to a certain height, the round nut is screwed back and tightened. When the jack is lowered, the round nut needs to be loosened first, and then the piston rod is lowered. However, since the jack is in a load state when the aircraft is lifted, according to the locking principle, a large axial locking force is usually generated at the position of the nut, which makes it difficult to dismount the nut.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1-7 As shown, this utility model provides a disassembly tool, including an operating component 1, a locking component 2, and a flexible component 3. The operating component 1 is provided with a connecting shaft 11 and a stop structure 12. The locking component 2 includes a rotating part 21 and a first locking part 22 disposed on the rotating part 21. The rotating part 21 is rotatably connected to the connecting shaft 11. The flexible component 3 is provided with a fixed end 31 and a free end 32. The fixed end 31 is connected to the operating component 1, and the free end 32 is provided with a second locking part 321 that can connect to the first locking part 22.Figures 1-4 As shown, when the dismounting piece 4 needs to be dismounted, first, the rotating part 21 needs to be attached to the dismounting piece 4, and then the free end 32 of the flexible piece 3 is pulled to connect the second locking part 321 with the first locking part 22, so that the flexible piece 3 is arranged around the dismounting piece 4, and then the operator can push the operating piece 1 in the first direction, the operating piece 1 can rotate around the connecting shaft 11 and rotate relative to the rotating part 21 in the first direction, at this time, the stop structure 12 arranged on the operating piece 1 can abut against the rotating part 21, the first direction is counterclockwise, and then it is not repeated. After the stop structure 12 abuts against the rotating part 21, the locking piece 2 and the dismounting piece 4 can be relatively fixed, and the fixed end 31, the free end 32 and the rotating part 21 form a clamping space for the dismounting piece 4, and the flexible piece 3 and the rotating part 21 can clamp the dismounting piece 4, at this time, the operator continues to rotate the operating piece 1 in the first direction to apply an effective force to the dismounting piece 4, and the rotating operating piece 1 can drive the dismounting piece 4 to rotate synchronously to loosen and dismount the dismounting piece 4.

[0038] When the dismounting piece 4 is in a narrow space, the rotating process of the operating piece 1 may be limited by the surrounding operation space, so that it cannot continue to rotate in the first direction, at this time, the operating piece 1 can be rotated in a second direction opposite to the first direction, the second direction is clockwise, and then it is not repeated. As shown, Figures 1-6 As shown, the operating piece 1 can rotate around the connecting shaft 11 and rotate relative to the rotating part 21 in the second direction, at this time, the stop structure 12 arranged on the operating piece 1 can be separated from the rotating part 21, the flexible piece 3 and the rotating part 21 loosen the dismounting piece 4, and the operating piece 1 rotating in the second direction does not drive the dismounting piece 4 to rotate in the second direction and tighten, and rotating the operating piece 1 in the second direction can also adjust the position of the rotating part 21 relative to the dismounting piece 4 to avoid the position limited by operation. When working in a narrow space, the dismounting tool provided by the utility model can complete the dismounting of the dismounting piece 4 in a smaller range of motion by repeating the above steps, the operation flexibility is higher, and the dismounting process is not easily disturbed by the space where the dismounting piece 4 is located.

[0039] The hollow structure can be arranged in the operation member 1, and the connecting shaft 11 is arranged in the hollow structure. The operation member 1 can be a hollow rod-shaped structure. In order to facilitate the installation of the locking member 2, an installation groove 14 can be arranged on the operation member 1, and the installation groove 14 is arranged on the side of the operation member 1 close to the to-be-detached member 4. In order to realize the rotational connection between the rotating part 21 and the connecting shaft 11, a through hole can be arranged on the rotating part 21, and the diameter of the connecting shaft 11 can be slightly smaller than the diameter of the through hole, so that the rotation of the rotating part 21 can be smoothly realized. The operation member 1 is also correspondingly provided with a mounting hole, and the diameter of the mounting hole can be slightly larger than the diameter of the through hole, so as to improve the stability of the connection between the connecting shaft 11 and the operation member 1. When the locking member 2 is installed on the operation member 1, the through hole and the mounting hole can be in communication with each other, so that the connecting shaft 11 can be arranged in the operation member 1 and the locking member 2. In order to avoid the position deviation of the connecting shaft 11 during the rotation of the rotating part 21 and to affect the detaching effect, a nut can be arranged at the position where the connecting shaft 11 passes through the operation member 1, so as to lock the connecting shaft 11 to the operation member 1.

[0040] As shown in Figure 2 In order to reduce the friction of the rotating part 21 during the rotation, a limiting groove 13 can be arranged on the side of the operation member 1 away from the to-be-detached member 4, and the direction of the slot opening of the limiting groove 13 and the installation groove 14 should be consistent. The locking member 2 is clamped between the installation groove 14 and the limiting groove 13, and the arrangement of the two on the opposite sides can also avoid the shaking or deviation of the locking member 2 during the rotation. The stop structure 12 is arranged in the limiting groove 13, and when the operation member 1 rotates in the first direction, the stop structure 12 arranged in the limiting groove 13 can abut against the rotating part 21.

[0041] In order to realize the detaching of the to-be-detached member 4, the locking member 2 needs to have a rotating part 21 that can abut against the to-be-detached member 4. In an embodiment, the rotating part 21 is in the shape of a boomerang, that is, the whole is in the shape of a flat V, and the operation member 1 can be provided with an operation end 15. The operation of the operation end 15 can drive the operation member 1 to rotate relative to the rotating part 21. In order to ensure that the force applied by the operation end 15 to the rotating part 21 can be uniformly transmitted to the to-be-detached object, a hole can be arranged at the V-shaped vertex of the rotating part 21, and a rotating shaft is arranged in the hole. Correspondingly, the depth of the installation groove 14 is greater than the depth of the limiting groove 13, so that the stop structure 12 arranged in the limiting groove 13 can play a role in stopping the rotating part 21. The groove bottom of the limiting groove 13 is located on the side close to the operation end 15, and when the operation member 1 rotates in the first direction, the stop structure 12 can abut against the position close to the V-shaped vertex of the rotating part 21. The stop structure 12 can be the groove bottom of the limiting groove 13, or a protruding structure arranged on the groove bottom of the limiting groove 13.

[0042] In order to enhance the connection between the detaching tool and the to-be-detached member 4 during the detaching process, as Figure 7As shown, a positioning surface 211 can be arranged at the V-shaped opening of the rotating part 21, and when disassembling, the positioning surface 211 can be close to the to-be-disassembled part 4. In an embodiment, the positioning surface 211 is in the shape of a circular arc, and the disassembling tool can be used to disassemble various circular parts, such as circular pipes or nuts, and when disassembling, the positioning surface 211 can be closely attached to the to-be-disassembled circular part.

[0043] A non-slip pad can be arranged on the positioning surface 211 to increase the friction between the positioning surface 211 and the to-be-disassembled part 4, so as to avoid relative sliding between the positioning surface 211 and the to-be-disassembled part 4 when the operating tool 1 is rotated. The non-slip pad can be made of rubber material. In order to facilitate the operator to rotate the operating tool 1 in the first direction or in the second direction, a non-slip layer can also be arranged on the operating tool 1, for example, a non-slip handle is sleeved on the outside of the operating tool 1. In other embodiments, a non-slip pattern can also be processed on the operating tool 1.

[0044] For the tool using a rigid part to disassemble, it is easy to cause scratches, indentations or abrasions on the surface of the to-be-disassembled part 4 during disassembly, and for the to-be-disassembled part 4 with an uneven surface, a convex or a concave, there is a large gap between the rigid disassembling tool and the to-be-disassembled part 4 during disassembly, and the disassembly is easy to slip. The flexible part 3 used in the utility model is not easy to leave marks on the surface of the to-be-disassembled part 4, and can better fit the to-be-disassembled part 4. Using the flexible part 3 to disassemble the to-be-disassembled part 4 can improve the success rate and disassembly efficiency of disassembly. The flexible part 3 can be a roller chain, which is provided with a plurality of chain links. In an embodiment, the outside of the chain is wrapped with a non-slip material to avoid the chain slipping on the surface of the to-be-disassembled part 4 during rotation of the operating tool 1, thereby affecting disassembly.

[0045] In addition to the rotating part 21, the locking part 2 also needs to have a first locking part 22 capable of being connected with the second locking part 321, so that when the operating tool 1 is rotated in the first direction, the flexible part 3 and the rotating part 21 can clamp the to-be-disassembled part 4. In order to simplify the connection process of the first locking part 22 and the second locking part 321, the first locking part 22 can be arranged as a hook, the second locking part 321 is arranged as a chain link, the chain link is provided with a pin shaft capable of cooperating with the hook, and when connected, the hook is hung on the pin shaft of the chain link, thereby realizing the connection and fixation of the first locking part 22 and the second locking part 321.

[0046] To adapt to disassembling different sizes of the to-be-disassembled part 4, at least two second locking parts 321 can be arranged at the free end 32 to expand the application range of the disassembling tool. When disassembling a to-be-disassembled part 4 of a larger size, the first locking part 22 can be connected with the second locking part 2 away from the fixed end 31, and when disassembling a to-be-disassembled part 4 of a smaller size, the first locking part 22 can be connected with the second locking part 2 close to the fixed end 31. During actual disassembling operation, after the selected second locking part 321 is connected with the first locking part 22, when the operating member 1 is rotated in the first direction, the flexible part 3 and the rotating part 21 can clamp the to-be-disassembled part 4.

[0047] In an embodiment, the operating member 1 is provided with a mounting boss 16, which is arranged at a side close to the operating end 15. The ratio of the distance from the mounting boss 16 to the connecting shaft 11 to the distance from the mounting boss 16 to the operating end 15 ranges from 1:5 to 1:4, which facilitates the operator to rotate the operating member 1 in the first direction or the second direction, improves the portability of operation, and enables the operating end 15 to exert a relatively small force to achieve the rotating purpose. The disassembling tool has a relatively good labor-saving performance. The fixed end 31 of the flexible part 3 is provided with a central through hole, and the mounting boss 16 is also correspondingly provided with a avoiding hole. When the fixed end 31 is connected with the mounting boss 16, the central through hole can be in communication with the avoiding hole, and a fastener can penetrate through the central through hole and enter the avoiding hole to realize the connection with the mounting boss 16. The fastener can be a pin shaft. The mounting boss 16 can fix the fixed end 31, and the first locking part 22 can lock the free end 32. The mounting boss 16 and the first locking part 22 can both be arranged at a side of the operating member 1 close to the to-be-disassembled part 4, i.e., the mounting boss 16 and the stop structure 12 are located at opposite sides of the operating member 1, so as to avoid the interference of the fixed flexible part 3 between the mounting boss 16 and the first locking part 22 with the rotating process of the operating member 1. The mounting boss 16 arranged at a side close to the to-be-disassembled part 4 can facilitate the flexible part 3 to lock the to-be-disassembled part 4.

[0048] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description.
