A column 7 abuts against the outer side of the control panel 4, and the column 7 is fixedly mounted on the inner wall of each sleeve plate 6. A screw 8 is fixedly mounted on the outer side of each sleeve plate 6. A through hole 9 is formed in each screw 8, which is inserted into two holes, 10 and 11 respectively. A positioning block 12 is fixedly mounted inside both holes 10 and 11, and a positioning groove 13 is inserted into each positioning block 12. The positioning groove 13 is located on the outer side of the screw 8. Hole 10 is located on the outer side of the door 2. The second insertion hole 11 is located on the outer side of the outer bracket 14. A nut 15 abuts against the outer side of the outer bracket 14, and the nut 15 is engaged with the outer side of the screw 8. A U-shaped groove 16 is provided on the outer side of the outer bracket 14. Two sleeve plates 6 are fitted onto the outer side of the control panel 4. The screw 8 is then passed through the interior of the first insertion hole 10 and the second insertion hole 11, with the positioning groove 13 fitted onto the outer side of the positioning block 12, and the nut 15 engaged with the outer side of the screw 8. Thus, the sleeve plates 6 and the outer bracket 14 can be directly fixed to the outer side of the door 2, thereby fixing the position of the sleeve plates 6. The U-shaped groove 16 on the outer bracket 14 can fix the probe head 5 to the U-shaped groove. Inside the slot 16, this structure is simple and easy to operate. It eliminates the need for drilling holes in multiple locations on the door 2, allowing for quick fixation of the control panel 4 and the probe head 5. The ends of the columns 7 abut against the outer side of the control panel 4. The columns 7 are evenly distributed on the inner walls of the two sleeve plates 6. The presence of the columns 7 creates a gap between the control panel 4 and the sleeve plates 6, facilitating heat dissipation during operation. The outer sides of the screws 8 abut against the interiors of the first insertion hole 10 and the second insertion hole 11, allowing the screws 8 to slide within these holes for easy connection between the sleeve plates 6 and the door 2. The outer side of the positioning block 12... The positioning blocks 12 are arranged in two sets, symmetrically distributed on the inner walls of the first insertion hole 10 and the second insertion hole 11. Through the cooperation between the positioning blocks 12 and the positioning groove 13, the positions of the sleeve plate 6 and the positioning blocks 12 can be guided and positioned. Grooves 17 are provided on the outer sides of both sleeve plates 6, and magnetic pieces 18 are fixedly installed inside the grooves 17. The grooves 17 and magnetic pieces 18 ensure that the two sleeve plates 6 do not fall apart when fitted onto the outside of the control panel 4. The fire warning device 3 described in this article is an existing device, therefore its principle and structure will not be described in detail here.

[0023] like Figure 3 and Figure 4As shown, a limiting hole 19 is provided on the outer side of the outer bracket 14. A T-shaped rod 20 is inserted into the limiting hole 19. A connecting plate 21 is fixedly installed at the end of the T-shaped rod 20. A protective plate 22 is fixedly installed on the outer side of the connecting plate 21. A rubber sheet 23 is fixedly installed on the protective plate 22. The T-shaped rod 20 can rotate inside the limiting hole 19. When personnel connect the control panel 4 and the probe head 5 through a cable, the protective plate 22 can be rotated and moved so that the rubber sheet 23 can abut against the outer side of the cable. The cable is squeezed between the outer bracket 14 and the rubber sheet 23, thereby securing the cable position without affecting the installation and subsequent use of the overall operation. The T-shaped rod 20 is close to the inner wall of the limiting hole 19, and the outer edge of the rubber sheet 23 is set in an inclined shape to facilitate the restriction of the cable position.

[0024] This utility model provides an electrical fire early warning device for low-voltage switchgear, the specific working principle of which is as follows:

[0025] In use, the cable is passed through the inside of the through hole 9, and then two sleeve plates 6 are fitted onto the outside of the control panel 4. During this process, the two sleeve plates 6 are connected together by the action of the magnetic piece 18. Then, the other end of the cable and the screw 8 are inserted into the inside of the first socket 10 and the second socket 11 in sequence. During this process, the positioning block 12 is inserted into the inside of the positioning groove 13, so that the sleeve plate 6 and the outer bracket 14 can abut against the outside of the box door 2. Then, the nut 15 is engaged with the outside of the screw 8 to fix the sleeve plate 6 and the outer bracket 14. Then, the operator connects the cable to the probe head 5 and places the probe head 5 inside the U-shaped groove 16. The position of the probe head 5 can be fixed by the nut. Then, the operator rotates the protective plate 22 so that the T-shaped rod 20 rotates inside the limiting hole 19. Then, the rubber piece 23 can be tightly attached to the outside of the cable, thereby limiting the position of the cable.

[0026] 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, the scope of which is defined by the appended claims and their equivalents.
