[0031] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0032] Screws are indispensable industrial necessities in daily life: such as tiny screws used in cameras, glasses, clocks, televisions, electronics, etc.; general screws used in televisions, electrical products, musical instruments, furniture, etc.; large screws and nuts are used in engineering, construction, and bridges; transportation equipment, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on earth, the function of screws will always be important.

[0033] like Figure 1 As shown, Figure 1 This is a schematic diagram of the installation status of the voltage regulator, in which A is a screw, B is a flange, and the voltage regulator is a Freda RTZ-50 / 0.4Q type (vertical, horizontal) or RTZ-31 / 50Q type (vertical, horizontal). The voltage regulator is installed on the ground with the rear part close to the wall, so that the rear part of multiple screws A is blocked by the wall and the front part is blocked by flange B, so that the operating space of the screws A is small.

[0034] In the maintenance of the pressure regulator, the necessary step for the maintenance of the shut-off valve and the replacement of the O-ring is to disassemble the shut-off valve. However, in the actual application of the pressure regulator, due to the limitations of the design and the geographical location of the installation, the existing wrench maintenance tools cannot be used well when disassembling and assembling screw A. Either the disassembly stroke is slow or the tool is too long or the operator cannot exert the normal corresponding force. The only way to disassemble and install is to slowly disassemble and install, and it is impossible to "show your hands and feet" to implement the operation.

[0035] The torque wrench repair tool provided in the present application extends into a relatively narrow screw operating space through a socket wrench. One end of the socket wrench is socketed on the nut of the screw, and the other end extends out of the operating space and engages with the hexagonal wrench. Rotating the hexagonal wrench drives the socket wrench to rotate, and then the screws are disassembled and installed, ensuring the maintenance and work efficiency of mechanical equipment.

[0036] The specific structure of the torque wrench repair tool provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0037] Reference Figure 2-Figure 6 As shown, the embodiment of the present application provides a torque wrench maintenance tool, including a socket wrench 1 and a hexagonal wrench 2. The main body of the hexagonal wrench 2 can be a straight-shaped, V-shaped or L-shaped. The socket wrench 1 adjusts the screw, and the hexagonal wrench 2 is clamped with the socket wrench 1. The hexagonal wrench 2 drives the socket wrench 1 to rotate, thereby installing or removing the screw;

[0038] like Figure 2 and Figure 3 As shown, the sleeve wrench 1 includes a sleeve assembly 10, a connecting rod assembly 20 and a hexagonal clamping block 30. The two ends of the connecting rod assembly 20 in the length direction are respectively connected to the sleeve assembly 10 and the hexagonal clamping block 30. The sleeve assembly 10 is sleeved with the nut end of the screw, and the inner wall of the sleeve assembly 10 is clamped with the nut of the screw. The hexagonal wrench 2 is clamped with the hexagonal clamping block 30, and the hexagonal wrench 2 drives the hexagonal clamping block 30, the connecting rod assembly 20, the sleeve assembly 10 and the screw to rotate;

[0039] like Figure 3 As shown, the sleeve assembly 10 includes a hexagonal sleeve 11 and a plurality of screws 12;

[0040] The hexagonal sleeve 11 can be a stainless steel sleeve, and its inner wall has six clamping planes. The clamping planes of the hexagonal sleeve 11 are provided with screw holes, and the screw rods 12 are screwed into the screw holes. The ends of multiple screw rods 12 extend from the outside to the inside into the inner cavity of the hexagonal sleeve 11, and the inner ends of multiple screw rods 12 are clamped with the side walls of the screw nuts.

[0041] Reference Figure 4 As shown, in some embodiments, three screws 12 are provided on the hexagonal sleeve 11, and the three screws 12 are evenly distributed around the axis of the hexagonal sleeve 11. The three screws 12 extend into the hexagonal sleeve 11 with equal lengths, and the inner ends of the three screws 12 are all clamped with the side walls of the screw nuts.

[0042] In some embodiments, six screw rods 12 are provided on the hexagonal sleeve 11, and the six screw rods 12 are evenly distributed around the axis of the hexagonal sleeve 11. The six screw rods 12 extend into the hexagonal sleeve 11 with equal lengths, and the inner ends of the six screw rods 12 are all clamped with the side walls of the screw nuts.

[0043] Reference Figure 3 and Figure 4 As shown, in some embodiments, the inner end of the screw rod 12 is rotatably connected to a splint 13, and the splint 13 is a plate body with a certain strength. By rotating the screw rod 12, the position of the splint 13 can be adjusted so that the spacing between multiple splints 13 matches the size of the screw to be operated. When installing or removing the screws, the outer walls of the multiple splints 13 are all clamped with the side walls of the screw nut.

[0044] In some embodiments, a slider 14 is provided at the end of the clamping plate 13, and the slider 14 can be a square slider. A slide groove 15 is provided on the inner wall of the end of the sleeve assembly 10, and the slider 14 is slidably connected to the slide groove 15;

[0045] When the screw rod 12 is rotated clockwise, the screw rod 12 drives the splint 13 to move outward, causing the slider 14 to slide outward in the slide groove 15. The slider 14 limits the splint 13 to prevent the splint 13 from rotating when the screw rod 12 is rotated; conversely, when the screw rod 12 is rotated counterclockwise, the splint 13 moves inward, and the slider 14 slides inward in the slide groove 15, thereby meeting the requirements of installing or removing screws of different types.

[0046] Reference Figure 4 As shown, in some embodiments, the inner wall of the sleeve assembly 10 is provided with an avoidance groove 16, the size of which matches the clamping plate 13. When the screw 12 is rotated clockwise to reach the limit position, the clamping plate 13 is inserted into the avoidance groove 16 and completely enters the avoidance groove 16.

[0047] Reference Figure 3As shown, in some embodiments, a connecting column 17 is provided at the end of the hexagonal sleeve 11. The connecting column 17 can be made of stainless steel and can be an integral structure with the hexagonal sleeve 11. The connecting column 17 and the connecting rod assembly 20 are detachably connected.

[0048] Reference Figure 5 As shown, in some embodiments, the connecting rod assembly 20 includes an outer tube body 21 and an inner rod body 22, the inner rod body 22 is inserted into the outer tube body 21, and the outer tube body 21 and the inner rod body 22 cannot rotate relative to each other. For example, the outer tube body 21 is a square tube body, and the inner rod body 22 is a square rod body. Both the outer tube body 21 and the inner rod body 22 can be made of stainless steel.

[0049] The top end of the outer tube body 21 is connected to the sleeve assembly 10, the inner rod body 22 is plugged into the outer tube body 21, and the bottom end of the inner rod body 22 extends out of the outer tube body 21 and is connected to the hexagonal clamp block 30;

[0050] The inner rod body 22 is plugged into the outer tube body 21. By adjusting the length of the inner rod body 22 extending out of the outer tube body 21, the length of the connecting rod assembly 20 can be adjusted, thereby adjusting the overall length of the socket wrench 1 to meet the needs of different usage locations.

[0051] In some embodiments, in order to facilitate fixing the length of the inner rod body 22 extending out of the outer tube body 21, a plurality of first fixing holes may be provided on the inner rod body 22, and the plurality of first fixing holes are arranged equidistantly in sequence along the length direction of the inner rod body 22, and a second fixing hole is provided at the bottom of the outer tube body 21, and bolts are inserted into the second fixing holes and the first fixing holes to fix the inner rod body 22 relative to the outer tube body 21.

[0052] In some embodiments, a limit groove 23 is provided on the outer wall of the inner rod body 22, and the limit groove 23 is a vertically arranged slide groove. A limit block 24 is provided on the inner wall of the outer tube body 21, and the limit block 24 can be a square card block. The limit block 24 is slidably connected to the limit groove 23, thereby preventing the outer tube body 21 and the inner rod body 22 from rotating relative to each other, reducing the friction loss between the outer tube body 21 and the inner rod body 22, and allowing the inner rod body 22 to extend and retract smoothly.

[0053] In some embodiments, a first through hole 25 is provided on the upper side wall of the outer tube body 21, and the connecting column 17 can be a square plug that matches the outer tube body 21. A second through hole 18 is provided on the connecting column 17. The connecting column 17 is plugged into the outer tube body 21, and bolts pass through the first through hole 25 and the second through hole 18 to fix the connecting column 17 and the outer tube body 21.

[0054] According to the above technical features, the working principle of the torque wrench repair tool provided by this application in actual application scenarios is:

[0055] like Figure 1 and Figure 6As shown in the figure, A is a screw and B is a flange. Before using the torque wrench maintenance tool to disassemble and assemble the screw A, adjust the multiple screws 12 according to the size of the screw A so that the spacing of the multiple clamping plates 13 matches the size of the screw A, and adjust the length of the connecting rod assembly 20 according to the size of the flange B;

[0056] To disassemble and assemble screw A, the staff member takes the socket wrench 1 and the hexagonal wrench 2 with both hands respectively, and sleeves the hexagonal socket 11 onto the screw A, so that the outer walls of the multiple clamping plates 13 are all engaged with the side walls of the nut of screw A. At this time, the hexagonal clamping block 30 is located in the unobstructed area below the flange B, and the hexagonal wrench 2 is engaged with the hexagonal clamping block 30. When the hexagonal wrench 2 is rotated forward, the socket wrench 1 and the screw A can be driven to rotate counterclockwise, so that the screw A is separated from the cut-off valve, thereby realizing the rapid disassembly of the screw A; conversely, when the hexagonal wrench 2 is rotated backward, the socket wrench 1 and the screw A can be driven to rotate clockwise, so that the screw A is screwed into the cut-off valve, thereby realizing the rapid installation of the screw A.

[0057] The torque wrench repair tool provided in the present application extends into a relatively narrow screw operating space through a socket wrench 1. One end of the socket wrench 1 is sleeved on the nut of the screw, and the other end extends out of the operating space and is engaged with the hexagonal wrench 2. Rotating the hexagonal wrench 2 drives the socket wrench 1 to rotate, and then the screws are disassembled and installed, ensuring the maintenance and work efficiency of mechanical equipment.

[0058] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0059] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
