Description

Technical Field

[0001] This utility model relates to the field of power maintenance tools, specifically to an anti-fall-off grounding rod. Background Technology

[0002] In routine maintenance, repair, and emergency repair operations in industries such as power, it is necessary to de-energize and ground equipment to ensure safety. A grounding rod is a device used to connect to the equipment's conductors or lead-in wires, thereby grounding the equipment through a grounding wire.

[0003] For example, announcement number CN212462052U, entitled "A Quick-Operating Anti-Loss Grounding Rod," includes a grounding clamp, a movable clip, and an operating rod. By setting the movable clip, the wire can be clamped in the middle of the grounding clamp, and the movable clip is fixed in the desired position using threads. This prevents detachment during windy weather and ensures reliable contact between the wire and the ground wire. An elastic component inside the connecting cavity generates elastic force, increasing the normal friction of the threads and preventing loosening when the movable clip is clamping the wire. The connection point of the insulating rod has a protrusion and a positioning hole. When multiple insulating rods are joined, the protrusion engages with the positioning hole, allowing for quick and reliable connection, saving operation time. The use of threaded clamping and anti-slip technology makes operation simple, time-saving, and labor-saving, effectively preventing loosening and detachment, ensuring operator safety, and significantly improving work efficiency.

[0004] However, the existing anti-detachment grounding rod uses an elastic element for adjustment at the anti-detachment clip. This adjustment structure has poor stability and is extremely susceptible to external environmental influences after being fixed, which is not conducive to outdoor operation. Therefore, it does not meet the current requirements, and an anti-detachment grounding rod is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-fall-off grounding rod to solve the problem mentioned in the background art that the existing anti-fall-off grounding rod uses an elastic element for adjustment at the anti-fall-off clamp, which has poor stability and is extremely susceptible to external environmental influences after being fixed, making it unsuitable for outdoor operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-fall-off grounding rod, comprising: a wire clamp head, an opening on the lower surface of the wire clamp head, a clip installed inside the opening, an assembly installed on the lower surface of the opening, a telescopic fitting installed on the outer wall of the assembly, and a rod body installed at the lower end of the telescopic fitting.

[0007] Preferably, the card includes a U-shaped card head, the lower end of which is fitted with a card rod, and the outer wall of the card rod has a plurality of first card holes arranged vertically at intervals.

[0008] Preferably, the assembly includes a hollow cylinder that communicates with an opening, a threaded assembly end is provided at the upper end of the hollow cylinder, and a first mating hole is provided on the outer wall of the hollow cylinder.

[0009] Preferably, the telescopic assembly includes a telescopic cylinder, an assembly cylinder is installed on the upper top of the telescopic cylinder, a second mating hole is provided on the outer wall of the assembly cylinder, and the second mating hole, the first mating hole and the first locking hole are connected by bolts.

[0010] Preferably, the upper end of the assembly cylinder is provided with a threaded assembly port, which is assembled with the threaded assembly end.

[0011] Preferably, the outer wall of the telescopic cylinder is provided with a plurality of vertically spaced second locking holes, and the outer wall of the rod is provided with a third docking hole, the third docking hole and the second locking holes are connected by bolts.

[0012] Preferably, a base is installed at the bottom of the telescopic cylinder, and two sets of limiting guide blocks are symmetrically installed on the outer wall of the base. Limiting guide grooves are opened on the inner walls of both sides of the rod. The limiting guide blocks slide up and down in the limiting guide grooves, and a sealing limiting block is provided at the upper opening of the limiting guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the U-shaped clamp head of the clamp is located inside the clamp head, and the clamp rod is installed in the hollow cylinder through the opening. When it is necessary to adjust the height of the U-shaped clamp head, the U-shaped clamp head is pulled up or down by moving up and down. After adjusting to the required range, the first clamp hole and the first docking hole are aligned at this range. The telescopic cylinder is installed outside the assembly cylinder. After installation, its second docking hole is aligned with the first docking hole, so that the user only needs to install bolts at the second docking hole. By inserting the bolts into the second docking hole, the first docking hole and the first clamping hole in sequence, the clamp rod can be fixed at this position. After installation, it is more stable and firm. In the outdoor environment, it is not easy to be affected by vibration or wind, thus improving safety.

[0015] (2) In this utility model, the telescopic cylinder can move up and down inside the rod. By moving up and down, the length of the telescopic cylinder can be changed, thereby changing the length of the entire grounding rod. After the telescopic cylinder moves to the required range, the second locking hole and the third docking hole within the range are aligned and fixed by adding bolts, so that the telescopic cylinder is restricted and cannot move, thus improving stability. When the telescopic cylinder moves up and down inside the rod, the limiting guide blocks on both sides of the telescopic cylinder will slide in the limiting guide groove. By limiting the telescopic cylinder, the lifting and lowering displacement is made smoother and more stable. When sliding to the top opening, the limiting guide block will contact the sealing limiting block and stop. By limiting the maximum displacement range by the sealing limiting block, the telescopic cylinder is prevented from detaching from the rod, thus improving safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of an anti-detachment grounding rod, comprising: a wire clamp head 1, an opening 101 on the lower surface of the wire clamp head 1, a clamping element 2 installed inside the opening 101, an assembly 3 installed on the lower surface of the opening 101, a telescopic fitting 4 installed on the outer wall of the assembly 3, and a rod 5 installed at the lower end of the telescopic fitting 4. Specifically, the clamping element 2 includes a U-shaped clamp head 201, a clamping rod 202 installed at the lower end of the U-shaped clamp head 201, and multiple clamping elements arranged vertically at intervals on the outer wall of the clamping rod 202. The first locking hole 203, the assembly 3 includes a hollow cylinder 301, the hollow cylinder 301 is connected to the opening 101, the upper end of the hollow cylinder 301 is provided with a threaded assembly end 302, the outer wall of the hollow cylinder 301 is provided with a first docking hole 303, the telescopic assembly 4 includes a telescopic cylinder 401, the upper top of the telescopic cylinder 401 is installed with an assembly cylinder 404, the outer wall of the assembly cylinder 404 is provided with a second docking hole 406, the second docking hole 406, the first docking hole 303 and the first locking hole 203 are connected by bolts.

[0023] The U-shaped clamp head 201 of the clamp 2 is located inside the clamp head 1, and the clamp rod 202 is installed inside the hollow cylinder 301 through the opening 101. When the height of the U-shaped clamp head 201 needs to be adjusted, it can be raised or lowered by pulling the U-shaped clamp head 201 up or down. After adjusting to the required range, the first clamping hole 203 and the first docking hole 303 are aligned at this range. The telescopic cylinder 401 is installed outside the assembly cylinder 404. After installation, its second docking hole 406 is aligned with the first docking hole 303. This allows the user to simply install a bolt at the second docking hole 406. By inserting the bolt into the second docking hole 406, the first docking hole 303, and the first clamping hole 203 in sequence, the clamp rod 202 can be fixed in this position. The installation is more stable and secure. In outdoor environments, the clamp 2 is less likely to be affected by vibration or wind, thus improving safety.

[0024] Furthermore, such as Figure 2 , Figure 3 As shown, the upper end of the assembly cylinder 404 is provided with a threaded assembly port 405, which is assembled with the threaded combination end 302. The assembly cylinder 404 is combined with the threaded combination end 302 through the threaded assembly port 405, which makes it easier to assemble the assembly 3 with the telescopic assembly 4, and the assembly is more stable and firm. At the same time, it makes the part detachable, which is convenient for subsequent maintenance.

[0025] Please see Figure 4The telescopic cylinder 401 has several vertically spaced second locking holes 402 on its outer wall, and the rod body 5 has a third docking hole 501 on its outer wall. The third docking hole 501 and the second locking holes 402 are connected by bolts. The telescopic cylinder 401 can move up and down within the rod body 5. The length of the telescopic cylinder 401 can be changed by the up and down movement, thereby changing the length of the entire grounding rod. After the telescopic cylinder 401 moves to the required range, the second locking holes 402 and the third docking holes 501 within that range are aligned and fixed by adding bolts, so that the telescopic cylinder 401 is restricted and cannot move, thus improving stability.

[0026] Furthermore, such as Figure 4 As shown, a base 403 is installed at the bottom of the telescopic cylinder 401. Two sets of limiting guide blocks 407 are symmetrically installed on the outer wall of the base 403. Limiting guide grooves 503 are opened on the inner walls of both sides of the rod body 5. The limiting guide blocks 407 slide up and down within the limiting guide grooves 503. A sealing limiting block 502 is provided at the upper opening of the limiting guide grooves 503. When the telescopic cylinder 401 moves up and down within the rod body 5, the limiting guide blocks 407 on both sides of the telescopic cylinder 401 slide within the limiting guide grooves 503. The limiting guide grooves 503 restrict the telescopic cylinder 401, making its up and down movement smoother and more stable. When it slides to the top opening, the limiting guide blocks 407 will contact the sealing limiting block 502 and stop. The sealing limiting block 502 limits the maximum displacement range and prevents the telescopic cylinder 401 from detaching from the rod body 5, thus improving safety.
