[0020] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0021] As Figures 1-3 shown, an electrical control switch device convenient for disassembly, assembly and maintenance according to the present utility model includes an outer shell 1. A switch 2 is arranged inside the outer shell 1. Wiring screws 3 are arranged on the outer wall of the outer shell 1. A mounting part 4 is fixedly arranged on the other side of the outer shell 1. A clamping part 5 is slidably connected inside the mounting part 4. By the setting that the clamping part 5 is composed of a square plate and a U-shaped plate, when the square plate is driven by the threaded rod 6 to descend, the U-shaped plate can still limit the square plate, so that the clamping part 5 is always limited by the mounting part 4;

[0022] A threaded rod 6 is fixedly connected to the top of the clamping part 5. A threaded sleeve 7 is threadedly connected to the outer wall of the threaded rod 6. A limit sleeve 8 is rotatably connected to the outer wall of the threaded sleeve 7. Through the setting of the limit sleeve 8, the threaded sleeve 7 is limited to prevent the threaded sleeve 7 from shifting. The limit sleeve 8 is fixedly connected inside the mounting part 4. A gear 9 is rotatably connected inside the mounting part 4. The gear 9 is fixedly connected to the top of the threaded sleeve 7. A rack 10 is engaged with the outer wall of the gear 9. The rack 10 is slidably connected inside the mounting part 4. A connecting rod 11 is fixedly connected to the outer wall of the rack 10. One end of the connecting rod 11 away from the rack 10 is fixedly connected to a hinge part 12.

[0023] Among them, when the control switch needs to be installed on the installation rod of the electrical cabinet, the installation part 4 can be aligned with the installation rod and inserted on the outer wall of the installation rod, so that the installation rod presses the first connecting rod 13 and the second connecting rod 14, and further enables the first connecting rod 13 and the second connecting rod 14 to push the hinge part 12 to slide along the inside of the installation part 4, so that the hinge part 12 drives the connecting rod 11 to move together. The movement of the connecting rod 11 will drive the rack 10 to slide along the inside of the installation part 4, so that the rack 10 drives the gear 9 to rotate, and further enables the gear 9 to drive the threaded sleeve 7 to rotate, so that the threaded sleeve 7 drives the threaded rod 6 to move. The movement of the threaded rod 6 will push the clamping part 5 to move and clamp on the outer wall of the installation rod, so as to achieve the effect of quickly installing the control switch and facilitate the staff to quickly install the control switch. When the control switch needs to be disassembled for inspection and maintenance, the handle 15 can be pulled to slide along the outer wall of the installation part 4, so that the handle 15 pushes the rack 10 to move back to its original position. Further, the rack 10 drives the threaded sleeve 7 to reverse through the gear 9, so that the threaded sleeve 7 pulls the clamping part 5 back into the inside of the installation part 4 through the threaded rod 6, so as to achieve the effect of quickly disassembling the control switch and facilitate the staff to repair the control switch. At the same time, when the rack 10 moves back to its original position, it will pull the hinge part 12 to slide along the inside of the installation part 4 through the connecting rod 11, so that the hinge part 12 pushes the first connecting rod 13 and the second connecting rod 14 to return to the V shape again and push the control switch away from the outer wall of the electrical cabinet installation rod.

[0024] Further, the hinge member 12 is slidably connected inside the mounting member 4. A first connecting rod 13 is hinged inside the hinge member 12. One end of the first connecting rod 13 is hinged to a second connecting rod 14, and the second connecting rod 14 is hinged to the outer wall of the mounting member 4. A handle 15 is fixedly connected to the top of the rack 10. The number of the handles 15 is set to two, and both of the two handles 15 are slidably connected to the outer wall of the mounting member 4. A connecting member 16 is fixedly connected to the outer wall of the handle 15. Through the arrangement of the connecting member 16, the two handles 15 are connected, so that no matter which handle 15 the staff pulls, the other handle 15 will be pulled together and fixed by the connecting member 16, facilitating the staff to pull different handles 15 according to the actual situation. The connecting member 16 is inserted into the inside of the mounting member 4. A shaping plate 17 is fixedly installed inside the mounting member 4. The number of the shaping plates 17 is set to two, and one of them is installed inside the clamping member 5. The two shaping plates 17 are respectively installed at the top and bottom of the airbag 18. When the compression spring 19 pushes the airbag 18 to recover, the airbag 18 will be limited by the shaping plate 17 and successfully recover, preventing the situation where the compression spring 19 pushes the airbag 18 to recover, but the airbag 18 only deforms and does not recover. An airbag 18 is fixedly connected to the outer wall of the shaping plate 17. A compression spring 19 is fixedly installed inside the airbag 18. The airbag 18 is inserted into the clamping member 5. A siren 20 is fixedly connected to the top of the airbag 18, and the siren 20 is inserted into the shaping plate 17.

[0025] Further, when the clamping member 5 moves to clamp the mounting rod, if the clamping member 5 and the mounting rod approach to a certain distance, the clamping member 5 and the mounting rod will squeeze the shaping plate 17, causing the shaping plate 17 to squeeze the airbag 18 to contract. Furthermore, the airbag 18 squeezes the compression spring 19 to contract and discharges the internal gas through the siren 20, making the siren 20 emit a sound to remind the staff that the quick installation of the control switch is almost completed, so that the staff can reduce the force of pushing the control switch, preventing the staff from continuing to push the control switch forcefully, which may cause damage to the installation components such as the first connecting rod 13 and the rack 10; after the control switch is removed from the mounting rod of the electrical cabinet, the compression spring 19 will reset and push the airbag 18 and the shaping plate 17 to reset, enabling the airbag 18 to draw in external gas through the siren 20 and recover, waiting to be squeezed during the next installation.

[0026] The utility model is provided with a clamping member 5 and a threaded sleeve 7. When it is necessary to install a control switch, the mounting member 4 can be aligned and inserted onto the mounting rod, so that the mounting rod presses the first connecting rod 13 and the second connecting rod 14, and finally the clamping member 5 clamps onto the mounting rod, so as to achieve the effect of quickly installing the control switch. When it is necessary to disassemble the control switch, the handle 15 can be pulled to slide, and finally the clamping member 5 re-enters the interior of the mounting member 4, so as to achieve the effect of quickly disassembling the control switch;

[0027] The utility model is provided with an airbag 18 and a siren 20. When the clamping member 5 moves to clamp the mounting rod, if the clamping member 5 and the mounting rod approach to a certain distance, the clamping member 5 and the mounting rod will press the shaping plate 17, and finally make the siren 20 emit a sound to remind the staff to reduce the pushing control.
