Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling for tractor production, in particular to a simple adjustable wrench structure. Background Art

[0002] During tractor production, in order to ensure the convenience of nut installation, people will use a socket wrench to quickly rotate the outside of the nut to complete the fast rotation installation of the nut, shortening the time required for tractor assembly;

[0003] However, the existing wrenches still have certain usage defects during use. For nuts installed in electronic equipment, due to the compact location inside the electronic equipment and the narrow operating space, it is difficult and laborious to install the nuts using the existing socket tools.

[0004] Patent application publication number CN217572673U discloses a socket wrench, which can reduce the slippage of the limit plate and the end of the fixed column during the rotation of the socket wrench. The limit plate is made of plastic material, which can effectively reduce the temperature generated by the friction between the fixed column and the limit plate compared to metal material. The second limit member further limits the sliding range of the sleeve to prevent the sleeve from falling off from the two ends of the sliding rod. The operating part is used to connect the sliding rod with an electric screwdriver. Using the electric screwdriver to operate the socket wrench improves the efficiency of disassembling and assembling the nut and improves the transmission effect of the transmission part and the sleeve.

[0005] In the above-mentioned public patent, the socket wrench in the patent solves the above-mentioned problems, but the socket wrench in the patent still has the following problems. During the use of the socket wrench, the socket needs to be sleeved on the outside of the nut, and the texture inside the socket needs to match the outside of the nut. After that, the wrench can drive the socket to rotate, completing the rotation process of the socket driving the nut, and realizing the installation or disassembly of the nut. The internal texture of the socket is fixed, resulting in a single socket that can only be installed for nuts of the same size. During the process of nut installation, sockets of different sizes need to be used, and multiple sockets of different sizes need to be carried for use, which seriously affects the convenience of using the wrench.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original wrench structure. Utility Model Content

[0007] The purpose of the present utility model is to provide a simple adjustable wrench structure to solve the problem that the internal texture of the socket proposed in the above background technology is fixed, resulting in a single socket only being able to be installed for nuts of the same size. During the process of nut installation, sockets of different sizes need to be used, and multiple sockets of different sizes need to be carried for use, which seriously affects the convenience of using the wrench.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a simple adjustable wrench structure, comprising a wrench body and a wrench toothed disc fixedly mounted on the outside of the wrench body;

[0010] A limiting structure is provided inside the wrench toothed disc, and the limiting structure can clamp nuts of different sizes.

[0011] Preferably, the height of the adjusting nut is greater than the thickness of the wrench body, and the upper and lower ends of the adjusting nut are located on the outside of the wrench body. The internal thread of the adjusting nut is installed with a limiting screw, and the limiting screw is slidingly connected to the wrench through groove. The height of the adjusting nut is greater than the thickness of the wrench body, so that the upper and lower ends of the adjusting nut are located on the outside of the wrench body, which is convenient for manual rotation of the adjusting nut.

[0012] Preferably, the length of the limit screw is smaller than the length of the wrench slot, and the center axis of the limit screw and the wrench body are in the same straight line. When the wrench is not in use, the limit screw can be retracted into the inside of the slot to avoid collision at the opening of the limit screw and protect the limit screw.

[0013] Preferably, the limiting structure includes a limiting groove, a docking block and a docking groove, the limiting screw has a limiting groove at one end close to the wrench gear disc, the docking block is fixedly installed inside the wrench gear disc, and a docking groove is provided on the outside of the docking block, and a mounting nut is clamped and installed between the docking groove and the limiting groove, the size of the wrench groove is larger than the size of the mounting nut, and the left and right ends of the mounting nut are respectively clamped and connected with the docking groove and the limiting groove, and a protective airbag is nested inside the docking groove and the limiting groove. The size of the wrench groove is larger than the size of the mounting nut, so that the mounting nut can be located inside the wrench groove for clamping.

[0014] Preferably, the docking block and the limit screw are respectively located at the left and right ends of the mounting nut, and the docking block is located inside the wrench slot. The docking block and the limit screw are respectively located at the left and right ends of the mounting nut.

At this time, nuts of different sizes can be disassembled and assembled through the docking groove and the limit groove, shortening the tractor assembly time and improving the convenience of using the wrench;

[0021] 2. The main structure of the wrench is simple, which can reduce production costs while ensuring the simplicity of production and facilitating popularization and production. By providing protective airbags inside the docking block and the limit screw, the wear between the docking block, the limit screw and the nut can be reduced;

[0022] 3. Furthermore, by adjusting the distance between the butt joint and the limit groove, it is easier to use nuts of different sizes, changing the characteristic that traditional socket wrenches can only be used for nuts of a single size;

[0023] 4. Furthermore, when the butt joint groove and the limit groove are worn due to long-term use, the opening angle of the butt joint groove and the limit groove can be directly corrected by grinding, thereby extending the service life of the wrench;

[0024] 5. Furthermore, by separating the wrench body from the splicing plate, the wrench can be quickly disassembled and assembled, ensuring the convenience of maintenance of the wrench. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In a specific embodiment, Figures 1-6 As shown, the basic use process of the wrench is disclosed;

[0035] A wrench body 1 and a wrench toothed disc 2 fixedly mounted on the outside of the wrench body 1;

[0036] A wrench slot 3 is provided inside the wrench toothed disc 2, a wrench through slot 6 is provided inside the wrench body 1, and an adjusting nut 4 is rotatably installed inside the wrench through slot 6;

[0037] A limiting structure is provided inside the wrench toothed disc 2, and the limiting structure can clamp nuts of different sizes;

[0038] The height of the adjusting nut 4 is greater than the thickness of the wrench body 1, and the upper and lower ends of the adjusting nut 4 are located on the outside of the wrench body 1. The internal thread of the adjusting nut 4 is installed with a limit screw 5, and the limit screw 5 is slidably connected with the wrench through groove 6;

[0039] The length of the limiting screw 5 is less than the length of the wrench slot 6, and the center axis of the limiting screw 5 and the wrench body 1 are in the same straight line;

[0040] The limiting structure includes a limiting groove 10, a docking block 8 and a docking groove 9. The limiting groove 10 is opened at one end of the limiting screw 5 close to the wrench gear disc 2. The docking block 8 is fixedly installed inside the wrench gear disc 2, and a docking groove 9 is opened on the outside of the docking block 8, and a mounting nut 7 is clamped and installed between the docking groove 9 and the limiting groove 10. The size of the wrench groove 3 is larger than the size of the mounting nut 7, and the left and right ends of the mounting nut 7 are respectively clamped and connected with the docking groove 9 and the limiting groove 10. The size of the wrench groove 3 is larger than the size of the mounting nut 7, and the left and right ends of the mounting nut 7 are respectively clamped and connected with the docking groove 9 and the limiting groove 10, and a protective airbag 16 is nested and installed inside the docking groove 9 and the limiting groove 10.

[0041] When using the simple adjustable wrench structure to install the nut of the tractor, the wrench toothed disc 2 can be directly put on the outside of the mounting nut 7 that needs to be removed, and then the limiting screw 5 can be made to contact the mounting nut 7, and the limiting screw 5 and the docking block 8 can clamp the two sides of the mounting nut 7, so that the mounting nut 7 is fixed. At this time, the wrench body 1 can be rotated to drive the wrench toothed disc 2 to rotate, and the rotation of the wrench toothed disc 2 and the wrench body 1 can drive the limiting screw 5 and the docking block 8 to rotate, so that the mounting nut 7 is rotated, and the mounting nut 7 can be disassembled and assembled, thereby completing the use process of the wrench.

[0042] In one specific embodiment, Figures 1-6 As shown, the specific use process of the wrench is disclosed;

[0043] The docking block 8 and the limiting screw 5 are respectively located at the left and right ends of the mounting nut 7, and the docking block 8 is located inside the wrench slot 3;

[0044] The butt joint groove 9 and the limit groove 10 have the same opening angle, and the butt joint groove 9 and the limit groove 10 are arranged opposite each other;

[0045] The limiting screw 5 is slidably connected to the wrench through slot 6 , and the length of the limiting screw 5 is greater than the distance between the adjusting nut 4 and the docking block 8 .

[0046] When using this simple adjustable wrench structure to install the nut of the tractor, it is necessary to sleeve the wrench toothed disc 2 on the outside of the mounting nut 7 and make the wrench groove 3 located on the outside of the mounting nut 7. At this time, the adjusting nut 4 can be rotated to make the limiting screw 5 move inside the wrench through groove 6. During the movement of the limiting screw 5, it will approach the direction of the docking block 8. At this time, the limiting groove 10 outside the limiting screw 5 will contact the mounting nut 7, and the docking groove 9 will engage with a corner of the mounting nut 7 away from the limiting groove 10. At this time, the fixing process of the wrench to the mounting nut 7 is completed. After that, the mounting nut 7 can be rotated and installed by rotating the wrench body 1. At this point, the installation process of the wrench to the mounting nut 7 is completed, which effectively improves the convenience of using the wrench.

[0047] Based on the above embodiments, Figure 1-Figure 5 As shown, the process of applying the wrench to nuts of different sizes is disclosed;

[0048] When using the simple adjustable wrench structure, the distance between the limiting screw 5 and the docking block 8 can be adjusted to change the distance between the docking groove 9 and the limiting groove 10, thereby achieving the effect of installing the wrench for nuts 7 of different sizes;

[0049] Moreover, after the wrench has been used for a long time, the docking groove 9 and the limiting groove 10 will be worn, which can be directly polished with a file to ensure the opening angle of the docking groove 9 and the limiting groove 10, thereby extending the service life of the wrench and increasing the overall practicality.

[0050] Based on the above embodiments, Figure 1-Figure 7 As shown, the process of disassembling and maintaining the wrench is disclosed;

[0051] A maintenance structure is provided on the outside of the wrench body 1, and the maintenance structure can disassemble the wrench;

At the same time, a splicing groove 15 is provided on the outer side of the splicing block 12, and a return spring 14 is fixedly installed on the end of the limit block 13 close to the splicing plate 11, and the end of the limit block 13 away from the return spring 14 is engaged with the splicing groove 15.

[0053] When the wrench fails, the wrench can be disassembled and its internal structure can be replaced. At this time, it is necessary to directly pull the splicing plate 11 to separate it from the wrench body 1. At this time, the limiting block 13 will be squeezed by the splicing groove 15 to move toward the inside of the splicing plate 11 and squeeze the return spring 14. At this time, the return spring 14 will contract. After the limiting block 13 is separated from the splicing groove 15, the splicing plate 11 can be separated from the wrench body 1.

[0054] After that, the mounting nut 7 can be further rotated to make the limiting screw 5 move inside the mounting nut 7, and the limiting screw 5 will be separated from the inside of the wrench body 1. Then, the mounting nut 7 can be removed, thereby completing the disassembly process of the wrench. After that, the damaged or severely worn structure of the wrench can be replaced, thereby ensuring the convenience of maintenance of the wrench, and the disassembly of the wrench is completed by separating the splicing plate 11 from the wrench body 1, which effectively improves the convenience of disassembly and maintenance of the wrench.
