Description

Technical Field

[0001] This utility model relates to the technical field of power construction inspection, and in particular to an insulating tool for power construction inspection. Background Technology

[0002] Insulation tools are used in high-voltage lines. The quality of insulation directly affects the stability and safety of the line. Their function is to help users check whether the insulation performance of electrical equipment meets safety standards, thereby reducing the occurrence of electrical accidents.

[0003] The Chinese Patent Network discloses an insulating tool for power construction testing, publication number CN217981583U. It includes two symmetrically arranged clamping bodies and a first handle and a second handle fixedly connected to their rear ends. Both the first and second handles have anti-slip sleeves fitted around their rear ends. The clamping bodies are divided into a current detection section, a clamping section, and a shearing section from front to back. The current detection section includes a housing containing a Hall current sensor. Limiting rods are symmetrically arranged at the top and bottom of the rear side wall of the housing, with springs connected to the rear ends of the limiting rods. A connecting part is provided between the first and second handles near the front end. This device, by incorporating the current detection section, clamping section, and shearing section, enables multi-functional use of the tool. Furthermore, the rear first and second handles and the anti-slip sleeves are all made of insulating material, effectively preventing injury to the user.

[0004] The solution also has the following problems: the insulating tool cannot be folded after use, which takes up a lot of space when stored. This is especially inconvenient when carrying a lot of tools during testing, thus affecting the efficiency of testing. Therefore, it has certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a power construction insulation testing tool. Utility Model Content

[0006] The purpose of this utility model is to provide an insulation testing tool for power construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrical construction testing insulation tool, comprising a clamp body, connecting blocks symmetrically installed on both sides of one outer end of the clamp body, a support frame installed on the outer end of the connecting blocks away from the clamp body, a semi-circular arc groove formed on one outer side of the support frame, a rotating block installed between the inner sidewalls of the support frame, a threaded rod installed on the wider outer side of the rotating block and inside the semi-circular arc groove, a fastening nut installed on the outside of the threaded rod, and an insulating handle installed on the narrower outer side of the rotating block.

[0008] Preferably, a fixing post is installed on the outer end of the insulating handle away from the rotating block, a strap is installed on one of the fixing posts, and a return spring is installed between the outer sides of the two support frames. When the strap is wrapped between the two fixing posts, the distance between the two insulating handles is reduced to the shortest distance and the return spring is compressed.

[0009] Preferably, a current sensor is installed on the outer side of the clamp body away from the two connecting blocks, and a display screen is embedded on the outer end of one of the insulating handles.

[0010] Preferably, the two outer sides of the rotating block are rotatably connected to the inner sidewall of the support frame, and the threaded rod slides synchronously inside the semi-circular groove when the rotating block rotates, and the rotating block can be rotated 180 degrees inside the support frame.

[0011] Preferably, the outer annular surface of the threaded rod is threadedly connected to the inner sidewall of the fastening nut, and when the fastening nut rotates outside the threaded rod, the outer side of the fastening nut will press against the outer side of the support frame.

[0012] Preferably, one end of each of the two inner side walls of the clamp is provided with a clamping groove, the inner side wall of the clamping groove is provided with a serrated shape, and the end of each of the two inner side walls of the clamp away from the clamping groove is provided with a shearing groove, one side of the inner side wall of the shearing groove is provided with a triangular blade shape.

[0013] In summary, this utility model has the following beneficial technical effects: When the strap is loosened, the return spring, due to its own elastic recovery deformation, generates an outward thrust that pushes the two support frames away from each other, thereby increasing the distance between the two insulating handles. The clamp body then opens and can be controlled by the two insulating handles. When the strap is wrapped around the two fixed posts, the two insulating handles can be fixed together, making it convenient to store the tool. The rotation degree of the rotating block inside the support frame allows the insulating handles to be rotated to a position that is basically parallel to the clamp body, greatly reducing the overall size of the tool and making it easy to carry and store. When the rotating block rotates to the required angle, the operator tightens the fastening nut. The fastening nut will move along the axial direction of the threaded rod and gradually approach the support frame, exerting a squeezing effect on the outside of the support frame, preventing the rotating block from rotating arbitrarily due to external force during use, ensuring the stability and reliability of the tool during use, making it convenient to operate and more practical.

[0016] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0017] An insulation testing tool for power construction, referring to Figure 1 - Figure 4 The device includes a clamping body 1. Connecting blocks 2 are symmetrically installed on both sides of one outer end of the clamping body 1. A support frame 3 is installed on the outer end of the connecting blocks 2 away from the clamping body 1. A semi-circular groove 301 is opened on one outer side of the support frame 3. A rotating block 4 is installed between the inner side walls of the support frame 3. A threaded rod 5 is installed on the wider outer side of the rotating block 4 and inside the semi-circular groove 301. A fastening nut 6 is installed on the outside of the threaded rod 5. An insulating handle 7 is installed on the narrower outer side of the rotating block 4.

[0018] Reference Figure 1 - Figure 3 A fixing post 8 is installed on the outer end of the insulating handle 7 away from the rotating block 4. A strap 9 is installed on one of the fixing posts 8. A return spring 10 is installed between the outer sides of the two support frames 3. When the strap 9 is wrapped between the two fixing posts 8, the distance between the two insulating handles 7 is reduced to the shortest distance and the return spring 10 is compressed. When the clamp 1 needs to be used, the strap 9 is removed from one of the fixing posts 8. When the strap 9 is loosened, the return spring 10 will generate an outward pushing force due to its own elastic recovery deformation, pushing the two support frames 3 away from each other, thereby increasing the distance between the two insulating handles 7. The clamp 1 then opens and can be controlled by the two insulating handles 7. When the strap 9 is wrapped around the two fixing posts 8, the two insulating handles 7 can be fixed together, making it convenient to store the tool.

[0019] Reference Figure 1 - Figure 2A current sensor 11 is installed on the side of the clamp 1 away from the two connecting blocks 2. A display screen 12 is embedded on the outer end of one of the insulating handles 7. When conducting power construction inspection, the current sensor 11 contacts the live object, and the current sensor 11 converts the detected current signal into an electrical signal and transmits it to the display screen 12. The display screen 12 processes and displays the received electrical signal. The operator can intuitively understand the current detected situation by observing the value on the display screen 12, thereby judging the operating status of the power equipment or line.

[0020] Reference Figure 1 - Figure 4 The outer two sides of the rotating block 4 are rotatably connected to the inner wall of the support frame 3. When the rotating block 4 rotates, the threaded rod 5 slides synchronously inside the semi-circular groove 301. The rotating block 4 can rotate 180 degrees inside the support frame 3. Because the rotating block 4 is rotatably connected to the inner wall of the support frame 3, when the operator applies external force to the insulating handle 7, the rotating block 4 will rotate around the rotation axis inside the support frame 3. The threaded rod 5 slides in the semi-circular groove 301 as the rotating block 4 rotates, playing a guiding and limiting role in the rotation range. The rotating block 4 can rotate 180 degrees inside the support frame 3, allowing the insulating handle 7 to be rotated to a position basically parallel to the clamp 1, greatly reducing the overall size of the tool and making it easy to store in a tool bag or toolbox, saving space and facilitating its use. For carrying and storage, the outer ring surface of the threaded rod 5 is threadedly connected to the inner wall of the fastening nut 6. When the fastening nut 6 rotates outside the threaded rod 5, the outside of the fastening nut 6 will press against the outside of the support frame 3. When the rotating block 4 rotates to the required angle, the operator tightens the fastening nut 6. Because the threaded rod 5 and the fastening nut 6 are threadedly connected, when the fastening nut 6 is tightened, the fastening nut 6 will move along the axial direction of the threaded rod 5, gradually approaching the support frame 3 and exerting a pressing effect on the outside of the support frame 3. The frictional force generated by this pressing fixes the rotating block 4 at the current angle, preventing the rotating block 4 from rotating randomly due to external force during use, ensuring the stability and reliability of the tool during use, and ensuring that the operator can accurately and stably perform power construction testing operations.

[0021] Reference Figure 1 - Figure 3The clamping body 1 has symmetrical clamping grooves 13 on one end of each of its two inner side walls. The inner side wall of the clamping groove 13 has a serrated shape. The clamping body 1 has a shearing groove 14 on one end of each of its two inner side walls away from the clamping groove 13. One side of the inner side wall of the shearing groove 14 is shaped like a triangular blade. When using this tool for clamping operations, the object to be clamped is placed into the clamping groove 13. The serrated design of the inner side wall of the clamping groove 13 increases the friction between the object and the clamp, making the clamping more stable and preventing the object from slipping during clamping. When a shearing operation is required, the object to be sheared is placed into the shearing groove 14. The clamping body 1 is closed by operating the insulating handle 7. The triangular blade-shaped structure on one side of the inner side wall of the shearing groove 14 applies shearing force to the object and cuts it. This tool has multiple functions, meets different operational needs in power construction, and improves the practicality and versatility of the tool.

[0022] The implementation principle of the electrical construction testing insulation tool of this utility model embodiment is as follows: When using the tool, when the clamp 1 needs to be used, the binding strap 9 is removed from one of the fixed posts 8. After the binding strap 9 is released, the return spring 10 generates an outward pushing force due to its own elastic recovery deformation, pushing the two support frames 3 away from each other, thereby increasing the distance between the two insulating handles 7. The clamp 1 then opens and can be controlled by the two insulating handles 7. When the binding strap 9 is wrapped around the two fixed posts 8, it can fix the two insulating handles 7 together, making it convenient to store the tool. When using the tool for clamping operations, the object to be clamped is placed into the clamping groove 13. The serrated design of the inner wall increases the friction between the object and the clamp, making the clamping more stable and preventing the object from slipping during clamping. When a cutting operation is required, the object to be cut is placed into the cutting groove 14, and the clamp 1 is closed by operating the insulating handle 7. The triangular blade-shaped structure on one side of the inner wall of the cutting groove 14 applies a shearing force to the object and cuts it. This achieves multiple functions of the tool, meets different operational needs in power construction, and improves the tool's practicality and versatility. During power construction inspection, the current sensor 11 comes into contact with the energized object. The current sensor 11 converts the detected current signal into an electrical signal and transmits it to the display screen 12. The display screen 12 displays the received signal. The received electrical signal is processed and displayed. The operator can intuitively understand the current status by observing the value on the display screen 12, thereby judging the operating status of the power equipment or line. Since the rotating block 4 is rotatably connected to the inner wall of the support frame 3, when the operator applies external force to the insulating handle 7, the rotating block 4 will rotate around the rotation axis inside the support frame 3. The threaded rod 5 slides in the semi-circular groove 301 as the rotating block 4 rotates, playing a guiding and limiting role in the rotation range. The rotating block 4 can be rotated 180 degrees inside the support frame 3, so that the insulating handle 7 can be rotated to a position that is basically parallel to the clamp body 1, which greatly reduces the overall size of the tool and makes it easy to store it in a tool bag or The toolbox is space-saving and easy to carry and store. When the rotating block 4 is rotated to the required angle, the operator tightens the fastening nut 6. Since the threaded rod 5 is connected to the fastening nut 6 by threads, when the fastening nut 6 is tightened, the fastening nut 6 will move along the axial direction of the threaded rod 5, gradually approaching the support frame 3 and exerting a squeezing effect on the outside of the support frame 3. The frictional force generated by this squeezing fixes the rotating block 4 at the current angle, preventing the rotating block 4 from rotating randomly due to external force during use, ensuring the stability and reliability of the tool during use, and ensuring that the operator can accurately and stably perform power construction testing operations. It is convenient to operate and has better practicality. The external helix opening angle of the threaded rod 5 is 20 degrees, and the thread self-locking condition meets the following formula calculation: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
