[0039] When operators want to disassemble or install larger-sized testing tools, they usually have to choose larger-sized pipe wrenches or chain pliers. However, larger-sized pipe wrenches or chain pliers are too heavy and inconvenient for operators to handle. In addition, frequently changing pipe wrenches or chain pliers to disassemble or install different-sized large-sized testing tools requires a lot of manpower and resources.
[0040] Based on practical experience and creative ability, the inventor designed a hook-shaped wrench for disassembly and assembly to improve the versatility, efficiency and reliability of the tool, save resources and simplify the manpower and material costs required for disassembly or installation.
[0041] like Figures 1 to 3 As shown, this application provides a hook-type wrench for disassembly and assembly, including a gripping part 1 and a locking part 2; the first end of the gripping part 1 is used for gripping, and the second end is arc-shaped; the locking part 2 is arc-shaped, and the first end of the locking part 2 is provided with a hook head 21 protruding from it, and the second end of the locking part 2 is detachably rotatably connected to the gripping part 1. The arc-shaped locking part 2 can rotate relative to the second end of the arc-shaped gripping part 1 at different preset angles to form different target inner edges 3, and the target inner edges 3 are used to fit the outer edge of the detection tool 4; wherein, the hook head 21 is on the same side as the target inner edge 3 for locking the detection tool 4.
[0042] Specifically, this application provides a hook-type wrench for disassembly and assembly, including a gripping part 1 and a locking part 2. It adopts a modular design concept, which facilitates the manufacturing, assembly and maintenance of the tool. At the same time, the modular design breaks through the design limitations of traditional large-size disassembly and assembly tools such as pipe wrenches or chain wrenches with large self-weight, improves the versatility of the tool and achieves lightweight design.
[0043] The first end of the gripping part 1 is used for gripping, which is the gripping position required for the operator to apply force. It can be provided with a structure such as frosted or granular protrusions to increase the friction coefficient of the surface of the first end of the gripping part 1, so that the first end of the gripping part 1 can effectively transmit force when the operator applies torque, prevent slippage or slippage, and improve the safety and reliability of the operation.
[0044] The second end of the gripping part 1 is arc-shaped, and the snap-fit part 2 is arc-shaped, so that the inner sides of the two structures can form an arc-shaped target inner edge 3 to fit the outer edge of the testing tool 4 with different outer diameters, so that a stable contact support surface is formed between the hook wrench for disassembly and assembly and the testing tool 4, ensuring the stability and reliability of torque transmission.
[0045] This application features a detachable, rotatably connected gripping part 1 and locking part 2, allowing the locking part 2 to rotate relative to the gripping part 1 at different preset angles. This enables the second arc-shaped end of the gripping part 1 and the inner arc side of the arc-shaped locking part 2 to form different target inner edges 3. This allows operators to utilize the hook-type wrench's adaptability to the outer edges of different sized and specifications of inspection tools 4 for disassembly or installation, improving the versatility of the disassembly and assembly tools provided by this application, reducing procurement and maintenance costs, avoiding frequent changes of handling tools, and improving work efficiency. During the assembly process of the gripping part 1 and locking part 2, the operator can rotate them relative to each other at the desired preset angle to form a suitable target inner edge 3 that fits the outer edge of the inspection tool 4 to be disassembled or installed. Then, fasteners 5 such as bolts, nuts, pins, and clamping pins are used to secure the connection between the two, completing the wrench assembly operation, followed by subsequent disassembly or installation work.
[0046] The hook head 21 protrudes from the first end of the snap-fit part 2 so that it can be accurately inserted into the hook hole or slot of the testing tool 4 during disassembly or installation operations, thereby achieving a rigid connection between the hook wrench for disassembly and installation and the testing tool 4, realizing reliable torque transmission, and ensuring stability and non-slippage during the disassembly or installation process.
[0047] In one embodiment, this application can use two hook wrenches for disassembly and assembly to complete the disassembly or assembly of the testing tool 4. The hook head 21 of one of the hook wrenches is inserted into one of the hook heads 21 or slots of the testing tool 4 to act as the back clamp of the other hook wrench, thereby fixing the testing tool 4. At the same time, the hook head 21 of the other hook wrench is inserted into the other hook head 21 or slot of the testing tool 4. The operator applies force through the hook wrench to complete the disassembly or tightening of the testing tool 4.
[0048] In another embodiment, this application can use a hook wrench for disassembly and assembly in conjunction with a caliper, pipe wrench, or similar tool to disassemble or install the testing tool 4. The caliper or pipe wrench acts as the back clamp of the hook wrench for disassembly and assembly to fix the testing tool 4. At the same time, the hook head 21 of the hook wrench is inserted into another hook head 21 or slot of the testing tool 4. The operator applies force through the hook wrench to complete the disassembly or tightening of the testing tool 4.
[0049] This application provides a hook-type wrench for disassembly and assembly, including a gripping part 1 and a locking part 2; the first end of the gripping part 1 is used for gripping, and the second end is arc-shaped; the locking part 2 is arc-shaped, and the first end of the locking part 2 is provided with a hook head 21 protruding from it, and the second end of the locking part 2 is detachably rotatably connected to the gripping part 1. The arc-shaped locking part 2 can rotate relative to the second end of the arc-shaped gripping part 1 at different preset angles to form different target inner edges 3, and the target inner edges 3 are used to fit the outer edge of the detection tool 4; wherein, the hook head 21 is on the same side as the target inner edge 3 for locking the detection tool 4. This application achieves modular design by setting a gripping part 1 and a locking part 2, which facilitates the manufacturing, assembly, and maintenance of the tool. It also breaks through the design limitations of traditional large-sized, heavy-duty pipe wrenches or chain wrenches, achieving lightweight design. Furthermore, this application features a detachable, rotatably connected gripping part 1 and locking part 2, allowing the locking part 2 to rotate relative to the gripping part 1 at different preset angles. This utilizes the arc-shaped second end of the gripping part 1 and the inner arc side of the arc-shaped locking part 2 to form different target inner edges 3. This allows operators to utilize the adaptability of the hook-type wrench to the outer edges of different sized and specifications of the testing tool 4 for disassembly or installation operations, improving the versatility of the disassembly and installation tool provided by this application, reducing procurement and maintenance costs, avoiding frequent changes of handling tools, and improving work efficiency. Moreover, the hook head 21 protrudes from the first end of the locking part 2, allowing it to accurately insert into the hook hole or slot of the testing tool 4 during disassembly or installation operations, achieving reliable torque transmission and ensuring stability and non-slippage during the disassembly or installation process. By applying this application, the problem of the large-size inspection tool 4 being too heavy to operate due to the large size of the pipe wrench or chain wrench, and the need to frequently change the pipe wrench or chain wrench to disassemble or install different sizes of large-size inspection tools 4, which requires a lot of manpower and resources, is solved.
[0050] like Figures 2 to 4 As shown, in some embodiments, the grip portion 1 includes a grip section 11 and a first latching section 12 connected to each other; the end of the grip section 11 facing away from the first latching section 12 is used for gripping; the first latching section 12 is arc-shaped to have a first latching inner edge 31, the first latching inner edge 31 is used to form a target inner edge 3 with the arc-shaped latching portion 2.
[0051] Specifically, in this application, the gripping part 1 includes a gripping section 11 and a first locking section 12 connected together. The end of the gripping section 11 facing away from the first locking section 12 is used for gripping, providing a longer lever arm for the operator, making the disassembly or installation process labor-saving and efficient. The first locking section 12 is arc-shaped with a first locking inner edge 31, which can form a partial contact with the outer edge of the testing tool 4 during disassembly or installation, so as to provide stable support and ensure the stability of torque transmission.
[0052] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the latching part 2 includes a second latching section 22 and a hook head 21 connected to each other. The hook head 21 protrudes from the first end of the second latching section 22, and the second end of the second latching section 22 is detachably rotatably connected to the first latching section 12. The second latching section 22 has a second latching inner edge 32, and the second latching inner edge 32 and the first latching inner edge 31 form a target inner edge 3. When the second latching section 22 rotates relative to the first latching section 12 at different preset angles, the second latching inner edge 32 and the first latching inner edge 31 form different target inner edges 3 to adapt to the outer edge of the detection tool 4 of different sizes.
[0053] Specifically, in this application, the snap-fit part 2 includes a second snap-fit section 22 and a hook head 21 connected to each other. The hook head 21 is disposed at the first end of the second snap-fit section 22 so that it can be accurately inserted into the hook hole or slot of the testing tool 4 during disassembly or installation operations, thereby achieving a rigid connection between the hook wrench for disassembly and installation and the testing tool 4, realizing reliable torque transmission, and ensuring stability and non-slippage during the disassembly or installation process.
[0054] The second snap-fit section 22 has a second snap-fit inner edge 32. The second snap-fit inner edge 32 can form a partial contact with the outer edge of the testing tool 4 during disassembly or installation to provide stable support and ensure the stability of torque transmission. The second snap-fit inner edge 32 and the first snap-fit inner edge 31 form a target inner edge 3. When the second snap-fit section 22 rotates relative to the first snap-fit section 12 at different preset angles, the second snap-fit inner edge 32 and the first snap-fit inner edge 31 form different target inner edges 3. This allows operators to use the characteristics of the hook-type wrench for disassembly and assembly to adapt to the outer edges of testing tools 4 of different sizes and specifications to achieve disassembly or installation operations. This improves the versatility of the disassembly and assembly tools provided in this application, reduces procurement and maintenance costs, avoids frequent replacement of handling tools, and improves work efficiency.
[0055] like Figure 4 and Figure 5 As shown, in some embodiments, the first snap-fit segment 12 has a first mounting hole 121 at one end opposite to the gripping segment 11; the second snap-fit segment 22 has a second mounting hole 221 at its second end; the first mounting hole 121 and the second mounting hole 221 are used to pass through fasteners 5 so that the second snap-fit segment 22 can be rotated relative to the first snap-fit segment 12 at different preset angles and then fastened.
[0056] Specifically, this application provides a first mounting hole 121 at the end of the first locking section 12 opposite to the gripping section 11, and a second mounting hole 221 at the second end of the second locking section 22. The configuration of the first mounting hole 121 and the second mounting hole 221 provides a precise assembly reference for the adjustable connection between the locking part 2 and the gripping part 1. Then, fasteners 5 such as bolts, nuts, pins, and clamping pins are used to achieve a tight connection between the two, thus completing the wrench assembly operation, so that subsequent disassembly or installation work can be carried out. In this way, the above configuration realizes the working mechanism of the hook wrench of this application for disassembly and assembly, which first adjusts to adapt to different outer diameter measuring tools 4, and then locks to form a stable torque transmission path, improving the versatility of the tool and improving work efficiency.
[0057] like Figures 1 to 5 As shown, in some embodiments, the gripping section 11 is integrally formed with the first locking section 12; the hook head 21 is integrally formed with the second locking section 22.
[0058] Specifically, this application improves the structural integrity of the grip section 1 by making the grip section 11 and the first locking section 12 integrally formed, reduces the connection interface or assembly gap, enhances the overall strength and rigidity of the grip section 1, avoids the risk of failure due to loose connection, deformation or breakage during high torque disassembly or installation, and also ensures the efficient transmission of torque from the grip section 11 to the first locking section 12, thereby improving the durability and reliability of the tool.
[0059] This application improves the structural integrity of the snap-fit part 2 by making the hook head 21 and the second snap-fit section 22 integrally formed, reducing the connection interface or assembly gap, and improving the overall strength and rigidity of the snap-fit part 2. At the same time, considering that the hook head 21 needs to withstand large shear forces and bending stresses during disassembly or installation, the integral forming design avoids safety hazards such as stress concentration and improves the impact resistance of the hook head 21 to ensure the stable transmission of torque from the gripping part 1 to the second snap-fit section 22 to the hook head 21.
[0060] like Figure 5 As shown, in some embodiments, the end of the hook 21 opposite to the second snap-fit section 22 has a first chamfer 211.
[0061] Specifically, this application provides a first chamfer 211 at the end of the hook head 21 that is away from the second locking section 22, in order to improve the alignment and smoothness of the hook head 21 when it is inserted into the hook hole or slot of the testing tool 4, thereby improving assembly efficiency. The first chamfer 211 forms a guide slope, which provides guidance when the hook head 21 approaches the hook hole or slot, thereby improving the ease of operation. At the same time, the first chamfer 211 can prevent scratching or damage to the testing tool 4 and extend the service life of the testing tool 4.
[0062] like Figure 5As shown, in some embodiments, the first end of the second snap-fit segment 22 is provided with a second chamfer 222 away from the outer edge of the hook head 21.
[0063] Specifically, this application provides a second chamfer 222 at the first end of the second locking section 22, which is opposite to the outer edge of the hook head 21. This makes the outer edge of the locking part 2 of the hook-type wrench smooth, avoiding scratches or cuts to the operator and improving tool safety. At the same time, the second chamfer 222 makes the outer edge of the locking part 2 rounded and smooth, improving the structural appearance quality.
[0064] like Figure 4 As shown, in some embodiments, a third chamfer 111 and a fourth chamfer 112 are provided at the connection position between the gripping section 11 and the first snap-fit section 12. The third chamfer 111 is connected to the inner edge 31 of the first snap-fit section, and the fourth chamfer 112 is located at the outer edge of the gripping section 1.
[0065] Specifically, this application provides a third chamfer 111 at the connection point between the grip section 11 and the first latching section 12. When the tool is in use, the third chamfer 111 is located on the inner side of the grip section 1 near the detection tool 4 to connect with the inner edge 31 of the first latching section. This provides a balanced surface at the connection point between the inner edge 31 of the first latching section and the grip section 11 to prevent scratching or damage to the detection tool 4 when the inner edge 31 of the first latching section contacts the detection tool 4, thereby extending the service life of the detection tool 4.
[0066] This application provides a fourth chamfer 112 at the connection point between the grip section 11 and the first locking section 12. When the tool is in use, the fourth chamfer 112 is located on the outer side of the grip section 1, away from the testing tool 4, and at the outer edge of the grip section 1. This provides a smooth outer edge at the connection point between the grip section 11 and the first locking section 12, preventing scratches or cuts to the operator and enhancing tool safety. Simultaneously, the third chamfer 111 and the fourth chamfer 112 make the grip section 1 overall rounded and smooth, improving the structural appearance quality.
[0067] like Figure 4 and Figure 5 As shown, in some embodiments, the first latching segment 12 has a first arcuate outer edge 122 at one end opposite to the gripping segment 11; the second latching segment 22 has a second arcuate outer edge 223 at its second end.
[0068] Specifically, this application provides a first arc-shaped outer edge 122 at one end of the first locking section 12 away from the gripping section 11, and a second arc-shaped outer edge 223 at the second end of the second locking section 22. This design eliminates sharp edges and improves operational safety when the operator installs the gripping part 1 and the locking part 2. At the same time, the arc-shaped outer edge design also prevents jamming or collision and scratching caused by sharp edges such as corners during the process of the locking part 2 rotating relative to the gripping part 1 to adjust the target inner edge 3, thus improving the smoothness of rotation adjustment.
[0069] like Figure 4 As shown, in some embodiments, the gripping section 11 has a through hole 113 at one end away from the snap-fit section.
[0070] Specifically, this application provides a through hole 113 at one end of the grip section 11 away from the locking section. This through hole 113 facilitates the storage and organization of the hook-type wrench used for disassembly and assembly. For example, the hook-type wrench can be suspended from a hook, tool rack, or tool cart via the through hole 113, making tool storage and management easier.
