Description

Technical Field

[0001] This invention relates to the field of power maintenance tools, and in particular to a multifunctional automatic power insurance maintenance tool. Background Technology

[0002] In the daily operation and maintenance and fault repair of power systems, voltage testers are a basic and essential safety testing tool widely used to determine whether electrical equipment or cables are energized. They are an important safeguard for the personal safety and standardized operation of power workers.

[0003] The core function of existing power testing tools is live-line detection, which means that by contacting the object being tested, the tool provides feedback on the live status based on its own light or sound prompts. However, in the actual power insurance maintenance process, workers often need to complete multiple consecutive operation steps. In addition to live-line verification, it often involves stripping the insulation layer of cables. Whether it is replacing faulty fuses, connecting new cables, or inspecting cable joints, the insulation layer on the surface of the cable must be accurately removed first to achieve effective connection or testing of conductive parts.

[0004] Traditional voltage testers do not have cable stripping capabilities, requiring maintenance personnel to carry specialized stripping tools such as wire strippers and electrician's knives. This increases the equipment burden on workers, especially in special scenarios such as working at heights or in confined spaces, where carrying and retrieving tools is even more inconvenient and may even affect work efficiency. Furthermore, frequent tool changes not only prolong the operation time of each repair but also increase the risk of tools falling due to cluttered placement, posing a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to address the following shortcomings in the prior art: traditional voltage testers do not have cable stripping function and are somewhat lacking in functionality. Therefore, this invention proposes a multi-functional automatic power insurance repair tool.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional automatic power fuse repair tool includes an insulating body. A conductive contact is fixedly installed at one end of the insulating body, and a rectangular rod is fixedly installed at the other end. The rectangular rod has multiple through holes for cables to pass through at equal intervals on its surface, and the diameter of the multiple through holes decreases sequentially. The rectangular rod has multiple sets of peeling components equidistantly arranged on its sidewalls. Each set of peeling components corresponds to a multiple perforation position. Each peeling component includes two sliding rods, two L-shaped blocks that are slidably fitted onto the two sliding rods, two arc-shaped blocks, and two peeling knives that are fixedly installed on the inner walls of the two arc-shaped blocks. The two sliding rods are fixedly installed on the left and right sides of the rectangular rod, respectively. The L-shaped blocks are connected to the rectangular rod through telescopic components. The top of each L-shaped block is provided with a locking component. The multiple sets of locking components are used to lock the multiple arc-shaped blocks.

[0007] Preferably, the telescopic component includes a telescopic spring sleeved on the slide rod, with both ends of the telescopic spring fixedly connected to the L-shaped block and the rectangular rod, respectively.

[0008] Preferably, a mounting block is fixedly installed at the end of the slide bar away from the rectangular bar, and the mounting block is used to restrict the separation of the L-shaped block from the slide bar.

[0009] Preferably, anti-slip pads are fixedly installed on both the left and right sides of the insulating body, and multiple anti-slip protrusions are fixedly installed at equal intervals on the surface of the anti-slip pads.

[0010] Preferably, protective components are provided at both ends of the insulating body, and the two sets of protective components are used to protect the conductive contact and the rectangular rod, respectively.

[0011] Preferably, the protective assembly includes two rotating rods and two protective frames respectively fixedly sleeved on the two rotating rods. A pair of fixing blocks are fixedly installed at both ends of the insulating body. The bottom ends of the multiple rotating rods are respectively rotatably installed on the upper surfaces of the two pairs of fixing blocks. Each pair of protective frames is used to cover the rectangular rod and the conductive contact. The upper surface of the insulating body is symmetrically provided with mounting openings. Threaded components are provided in the mounting openings. The two sets of threaded components are respectively used to control the rotation of the two pairs of rotating rods.

[0012] Preferably, the threaded component includes a T-shaped plate and two threaded rods symmetrically fixedly installed on the lower surface of the T-shaped plate. The top of the rotating rod is provided with a threaded groove that matches the thread on the surface of the threaded rod. The two threaded rods in each set of the protective components have opposite thread directions. The T-shaped plate is connected to the wall of the mounting opening through an elastic component.

[0013] Preferably, the elastic component includes multiple first spring rods, the two ends of which are fixedly connected to the lower surface of the T-shaped plate and the wall of the mounting opening, respectively.

[0014] Preferably, the locking assembly includes two second spring rods and two locking blocks respectively fixedly installed at the ends of the two second spring rods. The cross-section of the locking block is a right-angled triangle. The lower surface of the top of the L-shaped block is symmetrically provided with L-shaped openings. The two second spring rods are respectively horizontally fixedly installed in the two L-shaped openings. The outer wall of the arc-shaped block is provided with a slot for the top of the L-shaped block to be inserted. The left and right walls of the slot are provided with locking grooves for the locking blocks to be inserted.

[0015] Preferably, an L-shaped pull block is fixedly sleeved on one end of the second spring rod near the locking block, and the surface of the pull block is provided with anti-slip texture.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This tool uses an insulated body as its carrier. One end uses a conductive contact to perform the live detection function of a traditional voltage tester, while the other end uses a rectangular rod, a through-hole, and a matching stripping assembly to construct a cable stripping structure. This allows a single tool to simultaneously perform the dual core functions of "voltage testing + stripping". Compared to the traditional method of carrying multiple tools such as voltage testers and wire strippers, this tool significantly reduces the amount of equipment that maintenance personnel need to carry. It is especially suitable for special scenarios such as working at heights and in confined spaces, avoiding the burden of carrying and confusion caused by numerous tools, and significantly improving the efficiency of work preparation. 2. The rectangular pole has multiple through holes with progressively decreasing diameters, which can accommodate cables of different specifications. With multiple stripping components that correspond to each through hole, it can achieve precise stripping of cables of different diameters without the need to frequently change stripping tools, thus further expanding the applicability of the tool. 3. The locking assembly, through the cooperation of the second spring rod, the locking block, the arc block slot, and the locking groove, can quickly fix and unlock the arc block. The operation is simple and efficient, and it is convenient to quickly replace the peeling knife with severe wear. 4. The protective components at both ends of the tool's insulated body provide all-around protection for the conductive contacts and rectangular rod. When not in operation, the protective frame covers the conductive contacts and rectangular rod, preventing the conductive contacts from being damaged by collision or accidentally touching live parts, thus avoiding safety hazards. It also prevents the exposed peeler from causing cuts or foreign objects from blocking the opening, and forms an additional anti-fall buffer layer to prevent sharp parts from being directly impacted or damaged when dropped. Together with the structural strength of the insulated body, they together create a comprehensive safety barrier for operation and anti-fall protection. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-3 A multifunctional automatic power insurance repair tool includes an insulating body 1. A conductive contact 2 is fixedly installed at one end of the insulating body 1, and a rectangular rod 3 is fixedly installed at the other end. Multiple through holes 4 for cables to pass through are equidistantly opened on the surface of the rectangular rod 3, and the diameter of the multiple through holes 4 decreases sequentially.

[0021] Multiple peeling components are equidistantly arranged on the sidewalls of the rectangular rod 3. These components correspond to multiple perforations 4. Each peeling component includes two sliding rods 5, two L-shaped blocks 6 slidably mounted on the two sliding rods 5, two arc-shaped blocks 7, and two peeling blades 8 fixedly installed on the inner walls of the two arc-shaped blocks 7. The two sliding rods 5 are fixedly installed on the left and right sides of the rectangular rod 3, respectively. The L-shaped blocks 6 are connected to the rectangular rod 3 via telescopic components. Figure 7 As shown, the telescopic component includes a telescopic spring 9 sleeved on the slide rod 5. The two ends of the telescopic spring 9 are fixedly connected to the L-shaped block 6 and the rectangular rod 3, respectively. An installation block 10 is fixedly installed at the end of the slide rod 5 away from the rectangular rod 3. The installation block 10 is used to restrict the L-shaped block 6 from separating from the slide rod 5. The top of the L-shaped block 6 is provided with a locking component. Multiple sets of locking components are used to lock multiple arc-shaped blocks 7.

[0022] When it is necessary to determine whether electrical equipment or cables are energized, the operator holds the insulating body 1 as the gripping part and directly contacts the conductive contact 2 fixedly installed at one end of the insulating body 1 with the surface of the object being tested. The signal fed back by the voltage testing indicator module on the tool can quickly determine whether the object being tested is energized, thus completing the voltage testing operation.

[0023] When it is necessary to strip the cable, first select the through hole 4 with the matching diameter of the rectangular rod 3 according to the diameter of the cable to be stripped. Since the diameter of the multiple through holes 4 decreases in sequence, it can accurately adapt to cables of different specifications. After selecting the through hole 4, insert the end of the cable to be stripped into the through hole 4 from one side, so that the part of the cable to be stripped extends to the two arc blocks 7 of the stripping component corresponding to the through hole 4.

[0024] Then, the L-shaped blocks 6 on the two slide rods 5 corresponding to the through-hole 4 move closer to each other. The L-shaped blocks 6 slide along the slide rods 5 towards the rectangular rod 3, while compressing the telescopic spring 9 in the telescopic component sleeved on the slide rods 5, so that the arc-shaped blocks 7 connected at the top of the two L-shaped blocks 6 move closer to each other and fit against the cable surface. At this time, the stripping knife 8 fixed on the inner wall of the arc-shaped block 7 is in close contact with the cable insulation layer, and the stripping knife 8 will cut the cable insulation layer, thus completing the stripping operation.

[0025] Then remove the insulation layer of the cut cable and move the cable out of the through hole 4. After releasing the L-shaped block 6, the L-shaped block 6, the arc-shaped block 7 and the stripping knife 8 will move and reset quickly under the elastic potential energy of the telescopic spring 9.

[0026] Anti-slip pads 11 are fixedly installed on both the left and right sides of the insulating body 1, and multiple anti-slip protrusions 12 are fixedly installed at equal intervals on the surface of the anti-slip pads 11.

[0027] To improve grip stability, the anti-slip pad 11 is made of a high-friction elastic material that can fit snugly against the hand or insulating gloves. The evenly distributed anti-slip protrusions 12 further increase the roughness of the contact surface, effectively reducing the impact of hand sweat, oil, or dust in the working environment on grip, and preventing the tool from slipping during operations such as electrical contact, peeling and pulling.

[0028] Reference Figure 4 The insulating body 1 has protective components at both ends. Two sets of protective components are used to protect the conductive contact 2 and the rectangular rod 3, respectively. Each protective component includes two rotating rods 13 and two protective frames 14 fixedly fitted onto the two rotating rods 13. A pair of fixing blocks 15 are fixedly installed at both ends of the insulating body 1. The bottom ends of the multiple rotating rods 13 are rotatably mounted on the upper surfaces of the two pairs of fixing blocks 15. Each pair of protective frames 14 is used to cover the rectangular rod 3 and the conductive contact 2, respectively. The upper surface of the insulating body 1 has symmetrically opened mounting openings 16, each containing threaded components. Two sets of threaded components are used to control the rotation of the two pairs of rotating rods 13. Each threaded component includes a T-shaped plate 17 and two threaded rods 18 symmetrically fixedly installed on the lower surface of the T-shaped plate 17. Figure 8 As shown, the top of the rotating rod 13 is provided with a threaded groove 19 that matches the thread on the surface of the threaded rod 18. The two threaded rods 18 in each set of protective components have opposite thread directions. The T-shaped plate 17 is connected to the wall of the mounting port 16 through an elastic component. The elastic component includes multiple first spring rods 20, and the two ends of the multiple first spring rods 20 are fixedly connected to the lower surface of the T-shaped plate 17 and the wall of the mounting port 16, respectively.

[0029] The initial state of the protective components is a closed protective state. At this time, the conductive contact 2 at one end of the insulating body 1 and the rectangular rod 3 at the other end will be completely covered by the corresponding two sets of protective components. The two protective frames 14 in each set of protective components approach each other to form a closed space, which completely wraps the conductive contact 2, the rectangular rod 3 and the matching stripping components, thus achieving physical protection.

[0030] When tools are needed for voltage testing or cable stripping, the corresponding protective components must be opened first: the worker presses down on the T-shaped plate 17 at the corresponding position on the upper surface of the insulating body 1 with their fingers. After the T-shaped plate 17 is subjected to force, it compresses the multiple first spring rods 20 below it, causing the first spring rods 20 to contract and deform and store elastic potential energy. As the T-shaped plate 17 moves down, the two threaded rods 18 fixed on its lower surface move down synchronously. Since the surface thread direction of the two threaded rods 18 in each set of protective components is opposite, when the T-shaped plate 17 is rotated, the two threaded rods 18 will drive the two rotating rods 13 to rotate synchronously in opposite directions through the threaded engagement with the threaded groove 19. The rotating rods 13 rotate under the support of the fixed blocks 15 at both ends of the insulating body 1, causing the protective frame 14 fixedly sleeved on its surface to open to both sides, gradually exposing the conductive contact 2 or rectangular rod 3. The work can be completed when the protective frame 14 is opened to an angle that does not affect the operation.

[0031] When the work is completed and no tools are needed, the T-plate 17 is released. The T-plate 17 will quickly move upward and reset under the elastic potential energy of the multiple first spring rods 20. The two threaded rods 18 will also quickly move upward and reset. Through the cooperation of the threaded rods 18 and the threaded grooves 19, the rotating rod 13 is driven to rotate in the opposite direction, so that the two protective frames 14 move closer to each other until they cover the conductive contact 2 or the rectangular rod 3 again. The protective assembly returns to the initial closed protective state, completing the protection and locking of the core component.

[0032] In non-operational state, the protective frame 14 can completely cover the conductive contact 2 and the rectangular rod 3, effectively isolating impurities such as dust, oil, and moisture, preventing the conductive contact 2 from oxidizing and rusting, which would affect the accuracy of voltage detection, and preventing the through 4 on the rectangular rod 3 from being blocked by foreign objects and the blade of the peeling knife 8 from being damaged and dulled, significantly reducing the wear and tear of the core components and extending the overall service life of the tool.

[0033] When the conductive contact 2 is directly exposed, it is easily damaged by accidental contact with a live body or collision with a hard object. At the same time, there is a risk of electric shock caused by accidental contact by staff. The exposed peeler 8 may cause cuts to staff. The protective component avoids the above safety risks from the source through physical isolation, especially during tool transportation, storage and operation intervals, providing double safety protection for staff and tools themselves.

[0034] Meanwhile, if the tool is accidentally dropped during use, the closed protective frame 14 fits tightly, which can form a buffer when the tool is accidentally dropped, further protecting the internal components from impact damage.

[0035] Reference Figures 5-6 The locking assembly includes two second spring rods 21 and two locking blocks 22 respectively fixedly installed at the ends of the two second spring rods 21. The cross-section of the locking block 22 is a right-angled triangle, as shown below. Figure 9As shown, L-shaped openings 23 are symmetrically formed on the lower surface of the top of the L-shaped block 6. Two second spring rods 21 are horizontally fixedly installed in the two L-shaped openings 23 respectively. Figure 10 As shown, the outer wall of the arc-shaped block 7 is provided with a slot 24 for inserting the top of the L-shaped block 6. The cross-section of the slot 24 is rectangular. The left and right walls of the slot 24 are provided with locking slots 25 for inserting the locking block 22. An L-shaped pull block 26 is fixedly sleeved on one end of the second spring rod 21 near the locking block 22. The surface of the pull block 26 is provided with anti-slip texture.

[0036] The locking component is integrated between the L-shaped block 6 and the arc-shaped block 7. Through the cooperation of the second spring rod 21, the locking block 22, the slot 24, and the locking groove 25, the arc-shaped block 7 can be quickly fixed and unlocked. The operation process is as follows: Fixing the arc-shaped block 7: Align the top of the L-shaped block 6 with the slot 24 on the outer wall of the arc-shaped block 7 and insert it. During the insertion process, the groove wall of the slot 24 of the arc-shaped block 7 will squeeze the inclined surface of the locking block 22, pushing the locking block 22 to retract into the L-shaped opening 23, while compressing the second spring rod 21. When the top of the L-shaped block 6 is fully inserted into the slot 24, the two locking blocks 22 will correspond to the positions of the two locking slots 25 respectively. The locking blocks 22 will pop out under the action of the reset elastic force of the second spring rod 21 and accurately embed into the locking slot 25 of the groove wall of the slot 24. At this time, the arc-shaped block 7 and the L-shaped block 6 are firmly locked, and the peeling knife 8 maintains a stable cutting posture.

[0037] Unlocking operation of arc block 7: When it is necessary to adjust the position of arc block 7 or replace peeling knife 8, the operator pinches the L-shaped pull block 26 with his / her fingers. The anti-slip texture on the surface of pull block 26 can increase friction and prevent slippage. Then, control the two pull blocks 26 to move closer to each other. Pull block 26 drives the second spring rod 21 to retract, so that the locking block 22 disengages from the locking groove 25. At this time, the locking state of arc block 7 is released, and the top of L-shaped block 6 can be directly pulled out from slot 24 to complete the unlocking. The operation is simple and efficient, and it is convenient to quickly replace peeling knife 8 with more severe wear.

[0038] In this invention, the tool uses an insulating body 1 as a carrier. One end uses a conductive contact 2 to realize the live detection function of a traditional voltage tester, while the other end uses a rectangular rod 3, a through-hole 4, and a matching stripping assembly to construct a cable stripping structure. This allows a single tool to simultaneously possess the dual core functions of "voltage testing + stripping". Compared to the traditional mode of carrying multiple tools such as voltage testers and wire strippers, this tool significantly reduces the amount of equipment carried by maintenance personnel. It is especially suitable for special scenarios such as high-altitude operations and operations in confined spaces, avoiding the burden of carrying and confusion caused by numerous tools, and significantly improving the efficiency of work preparation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
