[0022] The utility model discloses a fuse holder that is easy to install and fix. It is mainly used when the fuse needs to be replaced, which is troublesome and has low disassembly efficiency. Moreover, the fuse holder is easy to become loose from the panel during long-term use, which may cause certain unexpected scenes.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A fuse holder that is easy to install and fix, comprising a control panel 1 and a fuse 2 arranged inside the control panel 1, a plug shell 3 is fixedly connected to the top of the control panel 1, a pressure plate 16 is slidably connected to the inside of the plug shell 3, and a locking mechanism for clamping and limiting the fuse 2 is arranged below the control panel 1; locking mechanism: the locking mechanism comprises an upper spring sheet 4 and a lower spring sheet 5 arranged inside the plug shell 3, a fixing rod 6 is fixedly connected to the side of the upper spring sheet 4, and a wedge block 7 is fixedly connected to the bottom of the fixing rod 6; a shell 17 is fixedly connected to the bottom of the control panel 1, a moving rod 10 is slidably connected to the inside of the shell 17, one end of the moving rod 10 is fixedly connected to the rotating plate 9, and a limiting plate 11 is also fixedly connected to the inside of the shell 17, a plurality of groups of slide grooves are arranged inside the limiting plate 11, a plurality of groups of slide columns 12 are arranged inside the slide grooves, and a clamping plate 13 is fixedly connected to the lower end of the slide column 12.

[0024] In this solution, the upper spring sheet 4 and the lower spring sheet 5 move relative to each other, so that the stability between the fuse 2 and the control panel 1 can be improved. At the same time, the wedge block 7 can push the moving rod 10 to drive the rotating plate 9 to rotate inside the housing 17. During the rotation of the rotating plate 9, the sliding column 12 slides inside the limit plate 11, so that the clamping plate 13 can be driven to perform secondary clamping on the bottom of the fuse 2, which can not only improve the stability of the installation of the fuse 2, but also help to increase the disassembly speed of the staff, and the work efficiency is high.

[0025] Among them, by mirroring the upper spring sheet 4 and the lower spring sheet 5, the rebound force after the two are fitted together can be maximized, and the contact stability between the fuse 2 and the control panel 1 can be improved. By driving the rotating plate 9 to move the multiple sets of clamping plates 13 sliding on the surface, the bottom of the fuse 2 can be clamped again, which can further improve the stability of the connection between the fuse 2 and the control panel 1.

[0026] Reference Figure 2 , Figure 3 and Figure 4 The clamping plate 13 is slidably connected to the rotating plate 9, a spring column 8 is arranged between the moving rod 10 and the control panel 1, the upper spring sheet 4 and the lower spring sheet 5 are slidably connected to the plug shell 3, two groups of copper plates 14 are arranged below the fuse 2, the upper spring sheet 4 and the lower spring sheet 5 are mirror-imaged inside the plug shell 3, and six groups of sliding columns 12 and clamping plates 13 are distributed above the rotating plate 9.

[0027] Among them, the clamping plates 13 evenly distributed above the rotating plate 9 can not only limit and fix the fuse 2 and the control panel 1, but also assist the staff to disassemble them quickly, making the installation convenient.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The clamping plate 13 is made of a material with high hardness, a gasket 15 is provided on the surface of the fuse 2, the fuse 2 is threadedly connected to the control panel 1 and the plug shell 3, the upper spring sheet 4 and the lower spring sheet 5 are made of a material with high elasticity, and the fixing rod 6 is slidably connected to the control panel 1 and the plug shell 3.

[0029] The connection position between the fuse 2 and the control panel 1 can be protected by providing the gasket 15 .

[0030] Working principle: When in use, insert the fuse 2 into the plug shell 3 and the control panel 1, and then use a screwdriver to drive the fuse 2 to rotate inside the control panel 1. When the fuse 2 rotates, it will move downward to push the pressure plate 16 to slide downward inside the fuse 2. At this time, the pressure plate 16 pushes the upper spring sheet 4 to squeeze the lower spring sheet 5. When the fuse 2 rotates, the upper spring sheet 4 and the lower spring sheet 5 are completely in contact. The two can generate a large rebound force, which will push the fuse 2 in the opposite direction, so that the fuse 2 is closely connected to the control panel 1, and the stability is high;

[0031] At the same time, when the upper spring sheet 4 moves downward, it drives the fixing rod 6 to move, and the movement of the fixing rod 6 pushes the wedge block 7 to move downward. The wedge block 7 pushes the moving rod 10 to slide inside the shell 17 through the inclined surface. The movement of the moving rod 10 drives the rotating plate 9 to rotate. The rotating plate 9 limits the sliding column 12 through the sliding groove provided inside and the limiting plate 11 provided above, which can drive the clamping plate 13 to clamp and fix the bottom of the fuse 2, which can further improve the stability of the fuse 2 installed inside the control panel 1, and has high safety.

[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
