Description

Technical Field

[0001] This utility model relates to the field of fuse holder fixing technology, and in particular to a fuse holder fixing device. Background Technology

[0002] Junction boxes play a vital role in modern electrical and communication systems. They not only improve signal transmission efficiency but also facilitate equipment installation and maintenance. Proper use of junction boxes allows for effective power management and distribution, better protection of wires, prevention of exposed wires, reduction of leakage risks, and prevention of accidental direct contact with wires, ensuring stable system operation. They are essential devices in circuit connections. However, when a fuse blows, or even worse, the fuse holder burns out, circuit repair requires replacing the fuse holder. Fuse holders are secured with screws, making disassembly and installation inconvenient. Improper disassembly of the junction box casing can lead to damage and insecure fixing, wasting repair time, incurring continued economic losses due to power outages, and creating safety hazards that seriously endanger personal safety.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a fuse holder fixing device, including an upper box 1, a lower box 2 slidably connected to the lower part of the upper box 1, the lower box 2 including a base plate 21, a branch pipe 23 fixedly connected to the upper part of the base plate 21, a protrusion 22 fixedly connected to the upper part of the base plate 21, a flat-bottomed screw 25 rotatably connected to the upper part of the protrusion 22, a fixing device 3 fixedly connected to the upper part of the base plate 21, the fixing device 3 including a concave plate 31, a fixing post 32 fixedly connected to the upper part of the concave plate 31, a fixing plate 36 fixedly connected to the upper part of the concave plate 31, a crescent plate 33 slidably connected to the inner side of the fixing plate 36, a sliding rod 34 fixedly connected to one side of the crescent plate 33, a spring 35 sleeved on the outer surface of the sliding rod 34, a pull block 37 fixedly connected to one side of the spring 35, and a fuse holder 4 slidably connected to the upper part of the fixing post 32.

[0020] In this embodiment, the crescent plate 33 and the fixing post 32 cooperate with each other, and the iron plate 42 is fixed between the two. By moving the crescent plate 33, the complete restriction of the iron plate 42 can be released, and the iron plate 42 can slide along the fixing post 32. Since the iron plate 42 is part of the fuse holder 4, the fuse holder 4 can be disengaged from the bottom concave plate 31. The crescent plate 33 and the fixing post 32 ensure that the fuse holder 4 will not move up and down, while the concave plate 31 ensures that the plastic shell 41 will not move around randomly. No screws are required for fixation, and disassembly is simple.

[0021] Example 2 like Figures 1-4As shown, the upper box 1 includes a slide plate 11, a slide plate 12 is slidably connected to the inner side of the slide plate 11, a column 13 is fixedly connected to the lower side of the slide plate 11, a sliding hole adapted to the bottom of the column 13 is provided above the branch pipe 23, one side of the crescent plate 33 is fixedly connected to one end of the spring 35, the outer surface of the slide rod 34 is slidably connected to the inner surface of the pull block 37, the fuse holder 4 includes an iron sheet 42, a plastic shell 41 is embedded and connected to one side of the iron sheet 42, a protrusion with the same diameter as the hole at one end of the iron sheet 42 is provided above the fixed column 32, a groove adapted to the bottom of the fuse holder 4 is provided above the concave plate 31, a through hole is provided on the side of the protrusion 22, two concave holes are opened at the bottom of the bottom plate 21 so as to be hung on the wall nail, a side notch plate 14 is fixedly connected to the lower side of the upper box 1, a semi-circular opening is provided on the side of the side notch plate 14, and a lower side plate 24 is fixedly connected to the upper side of the lower box 2, a semi-circular opening is provided on the side of the lower side plate 24.

[0022] In this embodiment, the sliding connection between the slide plate 12 and the slide rail plate 11 eliminates the need for repeated installation and disassembly of the upper box 1 during device maintenance, thus preventing the column 13 of the upper box 1 from breaking inside the branch pipe 23 due to improper operation and eliminating the risk of instability in the overall structure of the fixing device.

[0023] Working principle: like Figures 1-4 As shown, when replacing the wiring, the wire is inserted into the hole of the protrusion 22 through the notch in the side notch 14 on the side of the upper box 1 and the notch in the lower side plate 24 on the side of the lower box 2, and fixed with the flat-bottom screw 25. When the fuse blows or the fuse holder 4 burns out, pull the slide plate 12 to expose its internal structure, pull the pull block 37, the pull block 37 causes the spring 35 to contract, and then causes the slide rod 34 to slide within the pull block 37. The slide rod 34 is fixed on the crescent plate 33, so that the crescent plate 33 is away from the fixing post 32, and the fuse holder 4 can be removed from the fixing post 32. Replace the fuse holder 4 and connect it to the wire. Put the fuse holder 4 into the groove of the concave plate 31, release the force on the pull block 37, the spring 35 contracts, the crescent plate 33 returns to the initial position, fix the fuse holder 4, and close the slide plate 12.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
