[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model discloses a fuse plug with a quick-release structure, comprising a plug 1 and a fuse 3, wherein an inspection port 12 is arranged on one side of the plug 1, a quick-release base 2 opposite to the inspection port 12 is arranged inside the plug 1, clamps 21 are arranged at both ends of the quick-release base 2, both ends of the fuse 3 are clamped in the inside of the clamps 21, a fixing seat 23 is arranged at one end of the quick-release base 2, an arc-shaped cover 22 is fixedly arranged on one of the clamps 21, a U-shaped cover 24 clamped in the fixing seat 23 is movably sleeved on the other clamp 21, and a cover plate 4 is movably arranged inside the inspection port 12.

[0025] Specifically, both sides of the fixing seat 23 are provided with a card slot 231 and a receiving slot 232 located on one side of the card slot 231, and both sides of the U-shaped cover 24 are provided with a card block 241 and a limiting plate 242 located on one side of the card block 241. One end of the card block 241 extends to the inside of the card slot 231, and one end of the limiting plate 242 extends to the inside of the receiving slot 232. A limiting rod 233 is fixedly arranged inside the receiving slot 232, and a limiting slot 243 is arranged inside the limiting plate 242 to be sleeved with the limiting rod 233. One end of the U-shaped cover 24 is provided with a spring 25 connected to a side wall of the fixing seat 23. The initial state of the spring 25 is a stretched state, so that the spring 25 continuously applies elastic force to drive the card block 241 to be firmly engaged with the card slot 231. Figure 3 and Figure 4 , when unlocking fuse 3, Figure 1 From the perspective of perspective, first pull the U-shaped cover 24 downward to drive the block 241 out of the slot 231, and the limit rod 233 cooperates with the limit groove 243, so that when the block 241 is out of the slot 231, it cannot be pulled further, and the operation is more convenient. After the block 241 is out of the slot 231, pull the U-shaped cover 24 to one side so that the block 241 is opposite to the receiving slot 232, and a slot with the same width as the limit groove 243 is opened inside the block 241 to avoid the limit rod 233. When the block 241 is opposite to the receiving slot 232, release the U-shaped cover 24, and the spring 25 pulls the U-shaped cover 24 to drive the block 241 to move toward the inside of the receiving slot 232. Figure 4Since the length of the receiving groove 232 is greater than the clamping groove 231, when the clamping block 241 is pulled to the inside of the receiving groove 232 by the spring 25, the U-shaped cover 24 rises significantly to break away from the shielding of the fuse tube 3, and one end of the fuse tube 3 can be taken out from the inside of the clamp 21 where the arc cover 22 is not set, and then the other end of the fuse tube 3 can be pulled out from the inside of the arc cover 22. The operation method is simple and quick.

[0026] Specifically, a pin 11 is provided on one side of the plug 1, and the pin 11 is used to connect to a socket.

[0027] Specifically, a circle of steps 13 is provided inside the inspection port 12, a sealing gasket 15 is provided on one side of the step 13, a groove 14 is provided on one side of the inner wall of the inspection port 12, a buckle 16 which is engaged with the cover plate 4 is provided inside the groove 14, the cover plate 4 is installed inside the inspection port 12 through the buckle 16, one side of the cover plate 4 is in contact with the sealing gasket 15, so that the inspection port 12 remains sealed, and the setting of the groove 14 makes it convenient for users to move the cover plate 4.

[0028] Specifically, a silicone connection belt 17 having one end connected to one side of the cover plate 4 is further provided inside the plug 1 . The provision of the silicone connection belt 17 prevents the cover plate 4 from falling off after being separated from the inspection opening 12 .

[0029] Specifically, one side of the cover plate 4 is provided with a corrugated portion 41 with one end extending to the interior of the groove 14 . The provision of the corrugated portion 41 facilitates the user to move the cover plate 4 .

[0030] For details, see Figure 3 Since the arc cover 22 does not need to be operated, the arc cover 22 is staggered with the inspection port 12 so that the fixing seat 23 and the U-shaped cover 24 are directly opposite to the inspection port 12, which greatly improves the operating space for users during maintenance and is more convenient to use.

[0031] To sum up, the fuse plug with a quick-release structure is limited by the arc cover 22 and one end of the fuse 3, and then the other end of the fuse 3 is limited by the U-shaped cover 24. The U-shaped cover 24 is continuously pulled by the spring 25. The arrangement of the card slot 231 and the limiting plate 242 can quickly operate the U-shaped cover 24 to disengage the limiting position of the fuse 3, thereby realizing rapid disassembly and assembly, and can maintain good stability even when subjected to impact and vibration, thereby meeting the needs of users. The fixing seat 23 and the U-shaped cover 24 are directly opposite to the inspection port 12, which greatly improves the operating space for users during inspection and is more convenient to use.
