The wide variety of tools increases the weight of the tool bag, making it inconvenient for maintenance personnel to carry. Furthermore, live-line work is highly dangerous, requiring a safe distance to be maintained during testing. Existing testing equipment is generally short, which increases the testing risk. Therefore, to ensure a safe distance during testing and improve the safety of users, a lightning protection device testing tool is proposed.

[0003] For example, a lightning protection device testing tool disclosed in the authorization announcement number CN219039153U includes a housing; a slider is slidably connected inside the housing, a first spring is provided on one side of the slider, a test pen rod is horizontally installed through the upper middle part of one side of the slider, and a spiral wire is provided on the other side of the slider, the spiral wire being fixedly connected to one end of the test pen rod;

[0004] Although it achieves the goal of pushing the positioning block into the positioning groove when the positioning block is flush with the positioning groove by the elastic force of the second spring, further limiting and fixing the test pen rod, making it convenient for staff to perform lightning protection device testing, after the test is completed, the positioning block can be pulled into the storage groove by the pull rod, and the slider can be pushed to the right and reset in the housing by the elastic force of the first spring, pulling the test pen rod into the housing, which can store the test pen rod and make it easy to carry;

[0005] However, this does not solve the problem that existing testing tools are not conducive to simultaneous deployment and folding for storage, and are not suitable for testing lightning protection devices from different distances, thus affecting the safety of use. Utility Model Content

[0006] The purpose of this utility model is to provide a lightning protection device testing tool to solve the problem mentioned in the background art that the testing tool is not convenient to be deployed and folded for storage, which is not conducive to testing lightning protection devices from different distances and affects the safety of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lightning protection device testing tool, comprising a left scale and a placement frame. One end of the left scale is provided with the placement frame, and the other end of the left scale is provided with a first locking pin, which is threadedly connected to the left scale. A closed groove is provided on the surface of the left scale on one side of the first locking pin. A right scale is provided outside the left scale. A movable shaft is provided at the end of the right scale near the left scale, and the right scale is movably connected to the left scale via the movable shaft. The movable shaft is slidably connected to the closed groove. The first locking pin is slidably connected to the open groove. A telescopic frame is provided on the side wall of the right scale. A limit frame is provided on the side wall of the placement frame. A limit pin is slidably provided inside the limit frame. A spring is provided on the surface of the limit pin, and both ends of the spring are connected to the limit pin and the limit frame, respectively.

[0008] Preferably, the telescopic frame is provided with a sliding rod inside, and the sliding rod is slidably connected to the telescopic frame.

[0009] Preferably, a tension spring is installed at one end of the slide rod, and the tension spring is connected to the telescopic frame.

[0010] Preferably, an electroscope is installed at the other end of the slide rod, and a slider is provided on the side wall of the slide rod, and the slider is slidably connected to the telescopic frame.

[0011] Preferably, the surface of the telescopic frame is provided with multiple sets of pin holes at equal intervals, and the slider is provided with a second locking pin inside.

[0012] Preferably, the second locking pin is threadedly connected to the slider, and the second locking pin can be inserted into the pin hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the detection tool not only realizes the linkage unfolding and folding storage, which facilitates the detection of lightning protection devices from different distances, reduces space occupation and is easy to carry, but also improves the safety of use;

[0014] When performing leakage current detection on lightning protection devices, a safe distance must be maintained. The tool is currently in a folded state. First, pull out the limiting pin, which compresses the spring to pull the pin out from inside the right scale. Rotate the right scale, which rotates around the movable shaft. Simultaneously, pull out the right scale, causing it to slide the movable shaft within the closed groove. When the open groove rotates to the first locking pin position, move the right scale in the opposite direction to insert the first locking pin into the open groove. Tighten the first locking pin. With the threaded connection between the first locking pin and the left scale, the right and left scales are fixed in the unfolded state. To fold and store them, repeat the above steps in reverse. Then, unscrew the second locking pin and push the slider, which in turn moves the sliding rod to extend... The telescopic frame slides internally, and the slide rod moves the electroscope. Simultaneously, the slide rod pulls the tension spring, moving the electroscope to the desired position. Afterward, the second locking pin is inserted through the slide rod into the pin hole and tightened, maintaining the electroscope in its current detection position. When the slide rod needs to be retracted into the telescopic frame, the second locking pin is unscrewed. With the elasticity of the tension spring, the slide rod retracts and resets. Holding the left ruler, the electroscope is placed on the surface of the lightning protection device to perform the detection. This tool can be used in both folded and unfolded states, corresponding to two different detection distances. This allows for more flexible detection of lightning protection devices, enabling simultaneous unfolding and folding for storage, reducing space occupation and making it easy to carry. It facilitates detection of lightning protection devices from different distances, improving safety during use. Attached Figure Description

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-6 This utility model provides an embodiment of a lightning protection device testing tool, including a left scale 2 and a placement frame 1. One end of the left scale 2 is provided with the placement frame 1, and the other end of the left scale 2 is provided with a first locking pin 4, which is threadedly connected to the left scale 2. A closed slide groove 8 is provided on the surface of the left scale 2 on one side of the first locking pin 4. A right scale 5 is provided on the outside of the left scale 2. A movable shaft 3 is provided on the end of the right scale 5 near the left scale 2, and the right scale 5 is movably connected to the left scale 2 through the movable shaft 3. The movable shaft 3 is slidably connected to the closed slide groove 8. The first locking pin 4 is slidably connected to the open slide groove 7. A telescopic frame 6 is provided on the side wall of the right scale 5. A limit frame 15 is provided on the side wall of the placement frame 1. A limit pin 17 is slidably provided inside the limit frame 15. A spring 16 is provided on the surface of the limit pin 17, and the two ends of the spring 16 are respectively connected to the limit pin 17 and the limit frame 15.

[0024] The telescopic frame 6 is provided with a slide rod 13 inside, and the slide rod 13 is slidably connected to the telescopic frame 6;

[0025] A tension spring 9 is installed at one end of the slide rod 13 and is connected to the telescopic frame 6. An electroscope 14 is installed at the other end of the slide rod 13. A slider 11 is provided on the side wall of the slide rod 13 and is slidably connected to the telescopic frame 6.

[0026] The surface of the telescopic frame 6 is provided with multiple sets of pin holes 10 at equal intervals, and the slider 11 is provided with a second locking pin 12 inside. The second locking pin 12 is threadedly connected to the slider 11, and the second locking pin 12 can be inserted into the inside of the pin hole 10.

[0027] When performing leakage current detection on lightning protection devices, a safe distance must be maintained. The tool is currently in a folded state. First, pull out the limiting pin 17, which compresses the spring 16, thus pulling the limiting pin 17 out of the right scale 5. Rotate the right scale 5, which rotates around the movable shaft 3. Simultaneously, pull out the right scale 5, causing the movable shaft 3 to slide within the closed slide groove 8. When the open slide groove 7 rotates to the position of the first locking pin 4, move the right scale 5 in the opposite direction to insert the first locking pin 4 into the open slide groove 7. At this point, tighten the first locking pin 4. With the first locking pin 4 threadedly connected to the left scale 2, the right scale 5 and the left scale 2 are fixed in the unfolded state. When it is necessary to fold them up for storage, repeat the above operation in reverse to fold the right scale 5 and the left scale 2 up. Then, unscrew the second locking pin 12, push the slider 11, and the slider 11 drives the slide rod 13 to slide inside the telescopic frame 6. The slide rod 13 drives the electroscope 14 to move, and at the same time, the slide rod 13 pulls the tension spring 9. After moving the electroscope 14 to the use position, the second locking pin 12 is then inserted. The slider 11 is inserted into the pin hole 10 and the second locking pin 12 is tightened to keep the electroscope 14 in its current detection position. When it is necessary to retract the slider 13 into the telescopic frame 6, the second locking pin 12 is unscrewed. Under the elastic cooperation of the tension spring 9, the tension spring 9 can drive the slider 13 to retract and reset. Holding the left scale 2, the electroscope 14 is placed on the surface of the lightning protection device. The electroscope 14 is a product of the same type as the Sankesong SKS-YDQ model. Its working principle is based on the electrostatic effect of like charges repelling each other. When a charged object comes into contact with the metal part of the electroscope, the charge... The charge is conducted to the metal foil, causing it to open due to carrying the same type of charge. The foil connects to the internal circuitry, emitting sound and light to alert the user, thus detecting whether the surface is charged and completing the inspection of the lightning protection device. The tool can be used in both folded and unfolded states, with each state corresponding to a different detection distance. This allows for more flexible inspection of lightning protection devices, enabling simultaneous unfolding and folding for storage, reducing space occupation and making it easy to carry. It facilitates inspection of lightning protection devices from different distances, improving safety during use.

[0028] Working principle: When performing leakage current detection on lightning protection devices, a safe distance must be maintained. The tool is currently in a folded state. First, pull out the limiting pin 17, which compresses the spring 16 to pull the limiting pin 17 out of the right scale 5. Rotate the right scale 5, which rotates around the movable shaft 3. While rotating the right scale 5, pull it out, causing the movable shaft 3 to slide inside the closed slide groove 8. When the open slide groove 7 rotates to the position of the first locking pin 4, move the right scale 5 in the opposite direction to insert the first locking pin 4 into the open slide groove 7. Tighten the first locking pin 4. With the threaded connection between the first locking pin 4 and the left scale 2, the right scale 5 and the left scale 2 are fixed in the unfolded state. When it needs to be folded for storage, repeat the above operation in the reverse direction to fold the right scale 5 and the left scale 2. Then, pull out the second locking pin 17. 2. Unscrew the slider 11 and push it. The slider 11 drives the slide rod 13 to slide inside the telescopic frame 6. The slide rod 13 drives the electroscope 14 to move. At the same time, the slide rod 13 pulls the tension spring 9. After the electroscope 14 is moved to the use position, insert the second locking pin 12 through the slider 11 into the pin hole 10 and tighten the second locking pin 12 to keep the electroscope 14 in the current detection position. When it is necessary to retract the slide rod 13 into the telescopic frame 6, unscrew the second locking pin 12. With the elastic cooperation of the tension spring 9, the tension spring 9 can drive the slide rod 13 to retract and reset. Hold the left scale 2 and place the electroscope 14 on the surface of the lightning protection device to complete the detection of the lightning protection device. This tool can be used in both folded and unfolded states. The two states correspond to two different detection distances, which can make the detection of lightning protection devices more flexible. The above is the complete usage of the lightning protection device detection tool.
