[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a quick-change explosion-proof top panel for a special gas cabinet, including a set-top box 1, a top panel 2, and a movable panel 3. The movable panel 3 is rotatably mounted on one end of the set-top box 1 via two sets of symmetrically distributed telescopic components. The movable panel 3 is installed on the top panel 2 via a disassembly component. The disassembly component includes several U-shaped grooves 4 evenly distributed on the four sides of the movable panel 3. Several fastening bolts 5 are welded to the inner wall of the top panel 2 at equal intervals. The positions of the fastening bolts 5 correspond to the positions of the U-shaped grooves 4, and the outer walls of the fastening bolts 5 are threaded with first fastening nuts 6. By inserting the fastening bolts 5 into the U-shaped grooves and then tightening the first fastening nuts 6, the movable panel 3 and the top panel 2 can be fixedly connected. During disassembly, the first fastening nuts 6 are unscrewed, and the fastening bolts 5 are removed from the U-shaped grooves, allowing for quick disassembly of the movable panel 3 and facilitating the replacement of electrical components on the movable panel 3 according to different needs.

[0022] When it is necessary to replace the electrical components on the movable panel 3 to meet different customized requirements, activate the telescopic cylinder 12. The telescopic cylinder 12 drives the top panel 2 to rotate around the hinge 8 through the connecting piece, opening the top panel 2. Unscrew the first fastening nut 6 and remove the fastening bolt 5 from the U-shaped groove of the movable panel 3 to disassemble the movable panel 3. Then, install the new movable panel 3 according to the requirements. Align the U-shaped groove on the movable panel 3 with the fastening bolt 5 on the top panel 2, insert it, and tighten the first fastening nut 6 to complete the replacement of the movable panel 3.

[0023] When internal electrical components need to be inspected and maintained, the telescopic cylinder 12 can be activated to open the top panel 2, similar to the above, to facilitate maintenance operations. After maintenance is completed, the telescopic cylinder 12 can be activated again to reset and close the top panel 2.

[0024] An opening 7 is provided on the top panel 2, and the outer diameter of the movable panel 3 is larger than the diameter of the opening 7.

[0025] The top panel 2 is rotatably mounted on one end of the set-top box 1 via a hinge 8. The set-top box 1 is fixedly installed on the top of the special gas cabinet body 9. The top panel 2 can be opened by rotating the hinge 8, which facilitates the replacement of the movable panel 3 and the inspection and maintenance of the internal electrical components.

[0026] The telescopic assembly includes a first U-shaped frame 10, a second U-shaped frame 11, a telescopic cylinder 12, and a connector. The first U-shaped frame 10 is fixedly connected to the inner wall of the top panel 2, and the second U-shaped frame 11 is fixedly connected to the inner wall of the bottom end of the set-top box 1. The two ends of the telescopic cylinder 12 are rotatably connected to the first U-shaped frame 10 and the second U-shaped frame 11 respectively through the connector. The telescopic cylinder 12 is connected to the first U-shaped frame and the second U-shaped frame through the connector, and can drive the top panel 2 to rotate around the hinge 8 to realize the opening and closing action of the top panel 2.

[0027] The connector includes a connector 13, a connecting post 14, and a second fastening nut 15. One end of the telescopic cylinder 12 is fixedly connected to the connecting post 14. The connecting post 14 and the output end of the telescopic cylinder 12 are both fixedly connected to the connector 13. One end of each of the two connectors 13 is fixedly connected to the connecting post 14. One end of each of the multiple connecting posts 14 is provided with a threaded groove 16. The multiple threaded grooves 16 are threaded with the second fastening nut 15. The second fastening nut 15 fixes the connecting post 14 to the first U-shaped frame and the second U-shaped frame, while ensuring that the connecting post 14 can rotate relative to each other, so that the telescopic movement of the telescopic cylinder 12 can be smoothly transmitted.

[0028] Multiple connecting posts 14 pass through the adjacent first U-shaped frame 10 and second U-shaped frame 11 respectively, and the multiple connecting posts 14 are rotatably connected to the adjacent first U-shaped frame 10 and second U-shaped frame 11 respectively. This connection method ensures the stability and flexibility of the telescopic component and ensures that the top panel 2 can open and close smoothly.

[0029] Finally, it should be noted that: all parts not described in this utility model are the same as or can be implemented using existing technology. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
