[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 6 The dustproof component of the mining cabinet instrument includes a dustproof mechanism installed inside the cabinet 1. The dustproof mechanism includes a mounting component 2 and several mounting boxes 3. Several mounting boxes 3 are installed sequentially on one side of the mounting component 2. The mounting component 2 is installed on the inner wall of the cabinet 1. A sealing cover 4 is connected to the opening on one side of the mounting box 3. A sealing gasket 5 is placed between the mounting box 3 and the sealing cover 4. A wire hole 301 is opened through the bottom of the mounting box 3.

[0021] like Figures 1 to 6 As shown, the main improvement of this utility model lies in enhancing the dustproof effect of the instruments inside the cabinet 1, such as... Figures 1 to 6 As shown, in the dustproof component of the mining cabinet instrument of this utility model, multiple mounting boxes 3 are installed inside the cabinet 1 through mounting component 2. Then, multiple instruments are placed into the mounting boxes 3 in sequence, and the connecting wires of the instruments are passed out from the wire hole 301 at the bottom of the mounting box 3 and connected to the components inside the cabinet 1 for monitoring. Finally, the sealing gasket 5 and the sealing cover 4 are installed in sequence at the opening of the mounting box 3 to complete the sealed installation of the instruments in the mounting box 3, reducing the possibility of dust entering the instruments inside the cabinet 1 during long-term use and improving the stability of the instruments. The installation position of the mounting component 2 can be adapted to the height of the observation window on the cabinet 1 door.

[0022] like Figures 3 to 6As shown, a rubber block 6 is fixedly connected to the bottom of the mounting box 3. A contraction hole 601, communicating with the wire-passing hole 301, is provided on the side of the rubber block 6 closest to the mounting box 3. By installing the rubber block 6 with the contraction hole 601 at the bottom of the mounting box 3, after the instrument's wires pass through the wire-passing hole 301, the contraction hole 601 inside the rubber block 6 tightly compresses the wires, thereby isolating the internal space of the mounting box 3 from the internal space of the cabinet 1 as much as possible, greatly improving the sealing and dustproof effect of the instrument within the mounting box 3.

[0023] like Figure 5 As shown, the contraction hole 601 is trumpet-shaped, with the larger end of the contraction hole 601 closer to the wire hole 301. The trumpet-shaped design of the contraction hole 601 allows the wire to pass through the wire hole 301 and out of the other end of the contraction hole 601 more smoothly, improving the efficiency of instrument installation.

[0024] like Figure 1 and Figure 2 As shown, the mounting assembly 2 includes a mounting plate 21 and several mounting bolts 22. The mounting bolts 22 pass through the four corners of the mounting plate 21 and are threadedly connected to the inner wall of the cabinet 1. By using multiple mounting bolts 22 to access the four corners of the mounting plate 21, instruments can be easily installed at any suitable location inside the cabinet 1, improving the applicability of instrument installation in mining cabinets.

[0025] like Figures 1 to 6 As shown, a splicing assembly connects the mounting plate 21 to the adjacent mounting box 3, and the mounting box 3 is spliced ​​and installed with the adjacent mounting box 3 via the splicing assembly. The splicing assembly facilitates the splicing and installation between the mounting box 3 and the mounting plate 21, as well as the splicing and installation between the mounting boxes 3.

[0026] like Figures 1 to 4 As shown, the sealing cover 4 is a transparent plate. Each of the four corners of the sealing cover 4 away from the mounting box 3 is connected to a hand-tightening bolt 41. The threaded rods of the four hand-tightening bolts 41 pass through the four corners of the sealing cover 4 and the four corners of the sealing gasket 5, respectively, and are then threadedly connected to the four corners of the mounting box 3. The use of a transparent sealing cover 4 ensures a dustproof seal inside the mounting box 3, while also allowing for direct observation of the internal instrument data from the outside. The four hand-tightening bolts 41 facilitate quick and easy installation of the sealing cover 4 onto the mounting box 3, ensuring that the instruments do not fall out after installation. It should be noted that the transparent sealing cover 4 can be made of acrylic sheet, which ensures transparency, provides structural strength, and has a low manufacturing cost, making it suitable for mass production.

[0027] like Figures 2 to 6As shown, the splicing assembly includes splicing blocks 7 and T-shaped inserts 71. The splicing blocks 7 and T-shaped inserts 71 are fixedly connected to both sides of the mounting box 3. The top of the splicing block 7 has a T-shaped slot 701 that matches the T-shaped insert 71. The side of the mounting plate 21 away from the cabinet 1 is also fixedly connected to the splicing block 7. When installing the mounting box 3 inside the cabinet 1, the mounting plate 21 is first fixed inside the cabinet 1. Then, the T-shaped inserts 71 on the side of the mounting box 3 are inserted from top to bottom into the T-shaped slots 701 of the splicing blocks 7 on the side of the mounting plate 21. Then, according to the number of instruments to be installed, one or more mounting boxes 3 are installed sequentially on the other side of the mounting box 3 in the same manner. The use of the splicing blocks 7 and T-shaped inserts 71 allows for the adaptive installation of one or more mounting boxes 3 as needed to supply instruments.

[0028] like Figures 2 to 6 As shown, both the mounting plate 21 and the mounting box 3 have protrusions 72 fixedly connected to the side near the T-shaped slot 701. The T-shaped insert 71 has a groove 702 on the side away from the mounting box 3, and the protrusions 72 and grooves 702 are matched. When the T-shaped insert 71 is inserted into the T-shaped slot 701, the T-shaped insert 71 is pressed downwards. When the protrusion 72 moves into the groove 702, it can simply limit the T-shaped insert 71 and the T-shaped slot 701, preventing the T-shaped insert 71 from falling out of the T-shaped slot 701 without human intervention.

[0029] like Figures 4 to 6 As shown, several springs 8 are fixedly connected to the inner wall of the mounting box 3 on the side away from the sealing cover 4. The other end of each spring 8 is fixedly connected to a pressing plate 9, which is slidably connected to the inner wall of the mounting box 3. When installing the instrument into the mounting box 3, the instrument is pressed against the side of the pressing plate 9 as needed, and then fully pushed into the mounting box 3. The instrument's wires are then led out of the mounting box 3 through the wire hole 301. The sealing cover 4 is then placed against the outside of the instrument, and the sealing cover 4 is fixed to the mounting box 3 using a hand-tightening bolt 41. The springs 8 push the pressing plate 9, preventing the instrument from shaking inside the mounting box 3 and ensuring that the instrument's display panel faces the sealing cover 4, thus facilitating the observation and recording of the instrument's monitoring data through the sealing cover 4.

[0030] like Figure 6 As shown, each of the four inner walls of the mounting box 3 has a limiting groove 302, and each of the four sides of the extrusion plate 9 is fixedly connected to a limiting block 10. The four limiting blocks 10 are slidably connected to the four limiting grooves 302 respectively. When the extrusion plate 9 moves telescopically within the mounting box 3, the sliding between the limiting blocks 10 and the limiting grooves 302 makes the telescopic movement of the extrusion plate 9 more stable and less prone to tilting.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
