Description

Technical Field

[0001] This utility model relates to the field of fuse technology, specifically to a convenient installation mechanism for high-voltage fuses. Background Technology

[0002] A fuse is an electrical device that breaks the circuit by melting its fusible element when the current exceeds a specified value. Fuses are current protection devices that utilize the principle that when the current exceeds a specified value for a certain period, the heat generated by the fuse itself melts the fusible element, thus breaking the circuit. Fuses are widely used in high and low voltage power distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, and are one of the most commonly used protective devices.

[0003] A known Chinese patent (application number: CN202122768280.9) discloses a self-locking high-voltage fuse, comprising an insulated outer cylinder and an inner cylinder for housing a fuse tube or fuse wire, and a self-locking mechanism. This self-locking mechanism includes a latch assembly and a socket-type lock cylinder. The latch assembly is installed at the lower end of the outer cylinder, and the socket-type lock cylinder is connected to the lower end of the inner cylinder. The socket-type lock cylinder and the inner cylinder form an assembly that can be inserted into or removed from the outer cylinder and the latch assembly. This assembly, in conjunction with the latch assembly, forms the self-locking mechanism and is used to lock or unlock the inner cylinder within the outer cylinder. This invention employs an internally and externally enclosed structure and an automatic locking function, completely avoiding the influence of the natural environment and external factors on the electrical and mechanical performance of the high-voltage fuse. It has unique advantages such as convenient and quick fuse replacement, simple operation, and overall reliability and durability.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned self-locking high-voltage fuse: the existing high-voltage fuse is usually installed and fixed by bolts, but the tightening of bolts depends on the experience of the construction personnel. If tools such as torque wrenches are not used, the tightness of different installation points may be inconsistent, which will affect the overall system reliability. Therefore, a convenient installation mechanism for high-voltage fuses is proposed. Utility Model Content

[0005] This utility model proposes a convenient installation mechanism for high-voltage fuses, which solves the problem in the existing technology where high-voltage fuses are usually installed and fixed with bolts. However, bolt tightening depends on the experience of the construction personnel. If tools such as torque wrenches are not used, the tightness of different installation points may be inconsistent, which will affect the reliability of the overall system.

[0006] The technical solution of this utility model is as follows: A convenient installation mechanism for a high-voltage fuse, comprising: two mounting plates;

[0007] A fixing plate is fixedly installed at the center of the top of the two mounting plates. Slots are provided on both sides of the fixing plate, and insert plates are inserted into the slots. A high-voltage fuse is provided on one side of the insert plate.

[0008] Two first triangular blocks are fixedly installed at the top and bottom of the insert plate. Multiple sliding rods are fixedly installed at the top and bottom of the fixed plate. One end of each sliding rod extends into the interior of the slot and is fixedly connected to a second triangular block. Multiple first springs are sleeved on the outer walls of the sliding rods. The top ends of the multiple first springs are connected to the inner wall of the slot, and the bottom ends of the multiple first springs are connected to the second triangular blocks.

[0009] Preferably, two first arc-shaped plates are fixedly installed on both sides of the two mounting plates, and a second arc-shaped plate is hinged to the end face of the two first arc-shaped plates.

[0010] Preferably, the top of the second arc-shaped plate is provided with a mounting groove, and a limit block is slidably connected inside the mounting groove.

[0011] Preferably, a second spring is fixedly installed on the inner bottom wall of the mounting groove, and the top end of the second spring is connected to the limiting block.

[0012] Preferably, the other end face of the two first arc-shaped plates is provided with an arc-shaped groove, and the second arc-shaped plate is inserted into the arc-shaped groove.

[0013] Preferably, the top of the two first arc-shaped plates is provided with multiple limiting holes, and the limiting block is inserted into one of the multiple limiting holes.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] During installation, the insert plate is inserted into the slot. Simultaneously, the first triangular block presses against the second triangular block, causing the second triangular block to move upwards. This causes the first spring to extend and retract, and the sliding rod to slide upwards. When the insert plate is fully inserted, the first spring drives the second triangular block to reset, causing it to contact the first triangular block and thus limit and fix the insert plate. For disassembly, pulling the sliding rod upwards moves the second triangular block upwards, allowing the insert plate to be pulled out of the slot, thus completing the removal of the high-voltage fuse. This achieves the goal of installing or removing the high-voltage fuse without the use of tools, effectively preventing issues caused by inconsistent tightness at different installation points that could affect the overall system reliability.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1 - Figure 5 A convenient installation mechanism for a high-voltage fuse includes: two mounting plates 1;

[0025] A fixing plate 2 is fixedly installed at the top center of two mounting plates 1. Slots 3 are provided on both sides of the fixing plate 2. Insert plates 4 are inserted into the slots 3. A high-voltage fuse 5 is provided on one side of the insert plate 4.

[0026] Two first triangular blocks 6 are fixedly installed at the top and bottom of the insert plate 4. Multiple sliding rods 7 are fixedly installed at the top and bottom of the fixing plate 2. One end of the multiple sliding rods 7 extends into the interior of the slot 3 and is fixedly connected to a second triangular block 8. Multiple first springs 9 are sleeved on the outer side wall of the multiple sliding rods 7. The top end of the multiple first springs 9 is connected to the inner wall of the slot 3, and the bottom end of the multiple first springs 9 is connected to the second triangular block 8.

[0027] The technical solution provided by this utility model is as follows: During installation, the insert plate 4 is inserted into the slot 3. At the same time as insertion, the first triangular block 6 presses against the second triangular block 8, causing the second triangular block 8 to move upward. The first spring 9 extends and retracts, and the slide rod 7 slides upward. When the insert plate 4 is inserted into the correct position, the first spring 9 drives the second triangular block 8 to reset, so that the second triangular block 8 abuts against the first triangular block 6, thus limiting and fixing the insert plate 4. During disassembly, by pulling the slide rod 7 upward, the second triangular block 8 moves upward. At this time, the insert plate 4 can be pulled out from the slot 3, thus completing the disassembly of the high-voltage fuse 5. This achieves the purpose of installing or disassembling the high-voltage fuse 5 without the use of tools, effectively preventing the problem of inconsistent tightness at different installation points affecting the overall system reliability.

[0028] Furthermore, two first arc-shaped plates 10 are fixedly installed on both sides of the two mounting plates 1. The end faces of the two first arc-shaped plates 10 are hinged to second arc-shaped plates 11. The top of the second arc-shaped plates 11 is provided with a mounting groove 12. A limit block 13 is slidably connected inside the mounting groove 12. A second spring 16 is fixedly installed on the inner bottom wall of the mounting groove 12. The top of the second spring 16 is connected to the limit block 13. The other end face of the two first arc-shaped plates 10 is provided with an arc-shaped groove 14. The second arc-shaped plates 11 are inserted into the arc-shaped groove 14. The top of the two first arc-shaped plates 10 is provided with multiple limit openings 15. The limit block 13 is inserted into one of the multiple limit openings 15.

[0029] Specifically, by attaching the first arc-shaped plate 10 to the utility pole at the required height, and then pressing the limiting block 13, the second spring 16 is retracted, causing the limiting block 13 to enter the mounting groove 12, and the second arc-shaped plate 11 is inserted into the arc-shaped groove 14. When the second arc-shaped plate 11 is inserted to a depth sufficient to fix the mounting plate 1 to the utility pole, the second spring 16 drives the limiting block 13 to reset, causing the limiting block 13 to insert into the limiting port 15, thereby limiting and fixing the first arc-shaped plate 10 and the second arc-shaped plate 11, thus achieving the purpose of installing the mounting plate 1. At the same time, through the multiple limiting ports 15, the size between the first arc-shaped plate 10 and the second arc-shaped plate 11 can be adjusted, thus allowing the mounting plate 1 to be installed on utility poles of different sizes.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
