Description

Technical Field

[0001] This utility model relates to the field of power surge protection boxes, and in particular to a redundant grounding structure for power surge protection boxes. Background Technology

[0002] A search of Chinese patents revealed publication number CN220233741U, which discloses a grounding structure and distribution box for a power distribution box. The box includes: a housing; at least one conductive element fixedly mounted on the housing; and a terminal block having multiple wiring holes spaced apart along its length, and threaded holes communicating with the wiring holes for screw assembly. One of the wiring holes is used to insert the conductive element, which is then fixed to the terminal block by screws. Because the conductive element can be assembled with any of the wiring holes on the terminal block, compared to existing technologies, users can flexibly adjust the installation position of the terminal block according to actual needs. Furthermore, since the conductive element is concealed by the terminal block, it is more aesthetically pleasing than the exposed mounting feet of existing technologies.

[0003] Existing grounding structures lack anti-loosening features. Generally, grounding conductors are connected to the power surge protection box via terminals, which are typically secured with bolts and clamps. During use, the conductors are easily loosened by external pulling, affecting connection stability and posing safety hazards. Furthermore, replacing the grounding rod is inconvenient, as the grounding plate and conductors are usually bolted together. Replacing the grounding rod requires tools, making the process cumbersome, increasing workload, and reducing efficiency. To address these issues, we propose a redundant grounding structure for the power surge protection box. Utility Model Content

[0004] The purpose of this utility model is to provide a redundant grounding structure for a power surge protection box, which has the advantages of anti-loosening function and easy replacement of grounding rods.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a redundant grounding structure for a power surge protector box, comprising a power surge protector box, a wiring mechanism provided on the surface of the power surge protector box, a fixed cylinder bolted to the bottom of the wiring mechanism, a threaded cylinder threaded to the surface of the fixed cylinder, a triangular groove provided on the inner wall of the threaded cylinder, a sliding rod slidably connected to the inner wall of the triangular groove, a first limiting plate fixedly sleeved on the surface of the sliding rod, a first spring fixedly connected between the first limiting plate and the inner wall of the fixed cylinder by a spring fixing member, a pressure plate bolted to one end of the sliding rod, and a wire provided between the pressure plates.

[0006] By adopting the above technical solution, after connecting the wire to the wiring mechanism, rotating the threaded cylinder causes the triangular groove to move. The movement of the triangular groove causes the sliding rod to move the pressure plate. The movement of the pressure plate presses and fixes the wire, which can achieve the purpose of preventing loosening, ensuring the stability of the connection and improving safety.

[0007] The present invention is further configured such that: the other end of the conductor is bolted to a mounting base; a grounding rod is slidably sleeved on the inner wall of the mounting base; a sliding cylinder is slidably sleeved on the surface of the mounting base; a second spring is sleeved on the surface of the mounting base; a trapezoidal groove is formed on the inner wall of the sliding cylinder; a snap-fit ​​rod is slidably connected to the inner wall of the trapezoidal groove; a second limiting plate is fixedly sleeved on the surface of the snap-fit ​​rod; a third spring is fixedly connected between the second limiting plate and the mounting base through a spring fixing member; and a snap-fit ​​groove is formed on the surface of the grounding rod, and the snap-fit ​​groove snaps into one end of the snap-fit ​​rod.

[0008] By adopting the above technical solution, the trapezoidal groove is moved by moving the sliding cylinder. The movement of the trapezoidal groove causes the locking rod to disengage from the locking groove under the action of the third spring, allowing the grounding rod to be removed and replaced. This method facilitates the replacement of the grounding rod, reduces workload, and improves replacement efficiency.

[0009] The present invention is further configured such that: the wiring mechanism includes a fixing block, the fixing block is bolted to the surface of the power supply surge protection box, a screw is threaded to the inner wall of the fixing block, a pressure plate is rotatably connected to one end of the screw, a conductive plate is bolted to the inner wall of the fixing block, and the wire is located between the conductive plate and the pressure plate.

[0010] By adopting the above technical solution and setting up a wiring mechanism, wiring can be easily completed.

[0011] The present invention is further configured such that: a retaining block is slidably sleeved on the inner wall of the mounting base, a conductive block is bolted to the inner wall of the mounting base, and the conductive block is electrically connected to the wire; a fourth spring is fixedly connected between the conductive block and the grounding rod through a spring fixing member.

[0012] By adopting the above technical solution, a clamping block, a conductor block, and a fourth spring are set up to clamp the grounding rod, preventing loosening and ensuring the stability of the connection.

[0013] The present invention is further configured such that a rubber pad is adhered to the surface of the pressing plate.

[0014] By adopting the above technical solution, rubber pads are installed to prevent damage to the wires.

[0015] The present invention is further provided that the surfaces of the threaded cylinder and the slide are provided with anti-slip texture.

[0016] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0017] The present invention is further configured such that an anti-detachment block is fixedly sleeved on the surface of the grounding rod.

[0018] By adopting the above technical solution and setting anti-detachment blocks, the stability of the grounding rod is improved.

[0019] The present invention is further configured such that one end of both the slide rod and the snap-fit ​​rod is arc-shaped.

[0020] By adopting the above technical solution, both the slide rod and the locking rod are designed with an arc shape at one end, making them easy to use.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the purpose of preventing loosening by connecting the wire to the wiring mechanism, rotating the threaded cylinder to move the triangular groove, which in turn causes the sliding rod to move the pressure plate, and the pressure plate to press and fix the wire. This ensures the stability of the connection and improves safety.

[0023] 2. This utility model uses a movable sliding cylinder to move the trapezoidal groove. The movement of the trapezoidal groove causes the locking rod to disengage from the locking groove under the action of the third spring, allowing the grounding rod to be removed and replaced. This method facilitates the replacement of the grounding rod, reduces workload, and improves replacement efficiency. Attached Figure Description

[0032] Example 1:

[0033] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A redundant grounding structure for a power surge protector box includes a power surge protector box 1. A wiring mechanism 2 is provided on the surface of the power surge protector box 1. A fixed cylinder 3 is bolted to the bottom of the wiring mechanism 2. A threaded cylinder 4 is threadedly connected to the surface of the fixed cylinder 3. A triangular groove 5 is formed on the inner wall of the threaded cylinder 4. A sliding rod 6 is slidably connected to the inner wall of the triangular groove 5. A first limiting plate 7 is fixedly sleeved on the surface of the sliding rod 6.

A pressure plate 9 is bolted to one end of the sliding rod 6. A wire 10 is arranged between the pressure plates 9. After connecting the wire 10 to the wiring mechanism 2, rotating the threaded cylinder 4 causes the triangular groove 5 to move. The movement of the triangular groove 5 causes the sliding rod 6 to move the pressure plate 9. The movement of the pressure plate 9 presses and fixes the wire 10, achieving the purpose of preventing loosening, ensuring the stability of the connection, and improving safety.

[0034] refer to Figure 4 The wiring mechanism 2 includes a fixing block 20, which is bolted to the surface of the power supply surge protection box 1. A screw 21 is threadedly connected to the inner wall of the fixing block 20. A pressure plate 22 is rotatably connected to one end of the screw 21. A conductive plate 23 is bolted to the inner wall of the fixing block 20, and the wire 10 is located between the wire 10 plate and the pressure plate 22. By setting the wiring mechanism 2, wiring is convenient.

[0035] refer to Figure 3 and Figure 5 A rubber pad 27 is bonded to the surface of the clamping plate 9. The rubber pad 27 is used to prevent damage to the wire 10.

[0036] refer to Figure 3 and Figure 6The surfaces of the threaded cylinder 4 and the slide cylinder 13 are provided with anti-slip textures 28. By setting the anti-slip textures 28, the hands are prevented from slipping and the operation is facilitated.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2 and Figure 6 The other end of the conductor 10 is bolted to a mounting base 11. A grounding rod 12 is slidably sleeved on the inner wall of the mounting base 11. A sliding cylinder 13 is slidably sleeved on the surface of the mounting base 11. A second spring 14 is sleeved on the surface of the mounting base 11. A trapezoidal groove 15 is opened on the inner wall of the sliding cylinder 13. A snap-fit ​​rod 16 is slidably connected to the inner wall of the trapezoidal groove 15. A second limiting plate 17 is fixedly sleeved on the surface of the snap-fit ​​rod 16. A third spring 18 is fixedly connected between the second limiting plate 17 and the mounting base 11 through a spring fixing member. A snap-fit ​​groove 19 is opened on the surface of the grounding rod 12, and the snap-fit ​​groove 19 snaps with one end of the snap-fit ​​rod 16. By moving the sliding cylinder 13, the trapezoidal groove 15 is moved. The movement of the trapezoidal groove 15 causes the snap-fit ​​rod 16 to disengage from the snap-fit ​​groove 19 under the action of the third spring 18, allowing the grounding rod 12 to be removed and replaced. This method facilitates the replacement of the grounding rod 12, reduces workload, and improves replacement efficiency.

[0039] refer to Figure 6 The inner wall of the mounting base 11 is slidably fitted with a clamping block 24, and the inner wall of the mounting base 11 is bolted with a conductive block 25, which is electrically connected to the wire 10. The conductive block 25 and the grounding rod 12 are fixedly connected by a fourth spring 26 through a spring fixing member. By setting the clamping block 24, the wire 10 and the fourth spring 26, they are clamped to the grounding rod 12 to prevent loosening and ensure the stability of the connection.

[0040] refer to Figure 1 and Figure 2 An anti-detachment block 29 is fixedly sleeved on the surface of the grounding rod 12. By setting the anti-detachment block 29, the stability of the grounding rod 12 is improved.

[0041] refer to Figure 5 and Figure 6 Both the slide rod 6 and the locking rod 16 have one end in an arc shape, which makes them easier to use.

[0042] Brief description of usage: After connecting and fixing the wire 10 to the wiring mechanism 2, rotate the threaded cylinder 4. The rotation of the threaded cylinder 4 causes the triangular groove 5 to move longitudinally. The movement of the triangular groove 5 causes the sliding rod 6 to move the pressing plate 9, thus pressing the wire 10. For disassembly, rotate the rotating cylinder in the opposite direction to reset the triangular groove 5. The reset of the triangular groove 5 causes the sliding rod 6, under the action of the first spring 8, to loosen the pressing plate 9, thus releasing the wire 10. The wire 10 can then be removed, completing the disassembly and achieving the purpose of preventing loosening. Move the sliding cylinder 13... The movement of the cylinder 13 causes the trapezoidal groove 15 to move. The movement of the trapezoidal groove 15 causes the locking rod 16 to disengage from the locking groove 19 under the action of the third spring 18. The grounding rod 12 is then removed, and a new grounding rod 12 is installed into the mounting base 11. The cylinder 13 is then released, and the cylinder 13, under the action of the second spring 14, causes the trapezoidal groove 15 to reset. The reset of the trapezoidal groove 15 causes the locking rod 16 to engage with the locking groove 19, thus fixing it in place and completing the installation. This facilitates replacement. The multiple grounding rods 12 and the redundant grounding design greatly improve reliability.
