[0023] 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.

[0024] like Figures 1 to 4 As shown, the present invention provides an explosion-proof electrical control box button operation mechanism, including an electrical control box body 1, a box door 2, an operation panel 3, and operation buttons 4. The left side of the back of the electrical control box body 1 is movably connected to the left side of the box door 2 via a pivot pin. The back of the operation panel 3 is movably connected to the front of the box door 2. The front of the operation panel 3 is fixedly connected to the back of the operation buttons 4. A top protective plate 5 is fixedly connected to the top of the operation panel 3. A protective cover 6 is movably connected to the front of the operation panel 3. The diameter of the inner wall of the protective cover 6 is the same as the diameter of the top protective plate 5. Insert rods 7 are fixedly connected to both sides of the bottom of the protective cover 6. A rubber snap ring 8 is sleeved on the bottom of the surface of the insert rod 7. Insert connectors 9 are fixedly connected to both sides of the bottom of the operation panel 3. The insert connectors 9 are inserted into the insert rods 7. An adjustment mechanism 10 is provided on the right side of the front of the box door 2. A limit component 11 is fixedly connected to the top of the left side of the operation panel 3. Anti-detachment components 12 are fixedly connected to the top of both sides of the front of the operation panel 3.

[0025] refer to Figure 1 The adjustment mechanism 10 includes an adjustment groove 101, which is located on the right side of the front of the door 2. The top of the inner wall of the adjustment groove 101 is movably connected to a screw 102 via a shaft pin. The top of the surface of the screw 102 is threadedly connected to a screw sleeve 103. The front side of the left side of the screw sleeve 103 is fixedly connected to the top of the right side of the operation panel 3.

[0026] As a technical optimization of this utility model, by setting an adjustment mechanism 10, if the position of the operation panel 3 is too high when the user uses the operation button 4, causing arm fatigue when clicking the operation button 4, the user can rotate the screw 102 and use the threaded connection between the screw 102 and the screw sleeve 103 to make the screw 102 drive the screw sleeve 103 to move up and down for adjustment. Then the screw sleeve 103 will drive the operation panel 3 to move and adjust, so as to better suit the user's height for use.

[0027] refer to Figure 1 The limiting component 11 includes a limiting block 111. The front right side of the limiting block 111 is fixedly connected to the top left side of the operation panel 3. A limiting groove 112 is opened on the left side of the front of the door 2. The inner wall of the limiting groove 112 is slidably connected to the surface of the limiting block 111.

[0028] As a technical optimization of this utility model, by setting a limiting component 11, during the rotation of the screw 102, the sliding cooperation between the limiting block 111 and the limiting groove 112 can limit the rotation of the operation panel 3, preventing the screw 102 from directly driving the screw sleeve 103 to rotate, which would cause the screw sleeve 103 to drive the operation panel 3 to rotate and thus affect the stability adjustment of the operation panel 3.

[0029] refer to Figure 1 , Figure 3 and Figure 4 The anti-detachment component 12 includes an anti-detachment block 121. The outer side of the back of the anti-detachment block 121 is fixedly connected to the top of both sides of the front of the operation panel 3. Anti-detachment grooves 122 are provided on both sides of the protective cover 6. The inner wall of the anti-detachment groove 122 is slidably connected to the inner side of the surface of the anti-detachment block 121.

[0030] As a technical optimization of this utility model, by setting the anti-detachment component 12, when the protective plate moves up and down to open or close, the protective cover 6 can avoid the protective cover 6 moving too far and causing the protective cover 6 to detach directly from the operation panel 3 through the sliding cooperation of the anti-detachment block 121 and the anti-detachment groove 122, thereby further improving the stability of use.

[0031] refer to Figure 2 An embedded groove 13 is provided at the bottom right side of the front of the door 2. A transmission disc 14 is provided inside the embedded groove 13. The bottom of the screw 102 passes through the inside of the embedded groove 13 and is fixedly connected to the top of the transmission disc 14.

[0032] As a technical optimization of this utility model, by setting the embedded groove 13 and the transmission disk 14, when the user needs to rotate the screw 102, the screw 102 can be driven to rotate by rotating the transmission disk 14, which provides the user with a point of force to apply force to the screw 102. The embedded groove 13 provides a convenient place to store the transmission disk 14, thereby reducing the area occupied.

[0033] refer to Figure 2 The front of the door 2 is provided with a wiring groove 15. The rear side of the top of the top plate 5 and the rear side of the bottom of the operation panel 3 are both fixedly connected with rubber blocking strips 16. The outer side of the back of the rubber blocking strips 16 is fixedly connected with the two sides of the front of the door 2. The inner walls of the wiring groove 15 are provided with auxiliary heat dissipation holes 17. The wiring groove 15 is connected to the adjustment groove 101 and the limiting groove 112 through the auxiliary heat dissipation holes 17.

[0034] As a technical optimization of this utility model, by setting a wiring groove 15, the wiring groove 15 can be used to conveniently store the wires when the control panel is electrically connected to the internal equipment of the electrical control box 1. By setting a rubber blocking strip 16, the wiring groove 15 can be separated from the outside world to accommodate different heights of the control panel 3. By setting an auxiliary heat dissipation hole 17, the heat generated by the connected wires during use can be discharged through the auxiliary heat dissipation hole 17.

[0035] refer to Figure 2 The surface of the transmission disc 14 is provided with anti-slip grooves 18, and there are several anti-slip grooves 18 distributed at equal intervals.

[0036] As a technical optimization of this utility model, by setting the anti-slip groove 18, when the user needs to rotate the transmission disk 14, the user's hand can contact the transmission disk 14 through the anti-slip groove 18, thereby greatly improving the friction between the user's hand and the transmission disk 14 and avoiding slippage.

[0037] The working principle and usage process of this utility model are as follows: During the use of the electrical control box 1, the operation buttons 4 on the operation panel 3 are covered by the protective cover 6, which effectively prevents accidental touches. When the user needs to operate the operation buttons 4, the user can directly pull the protective cover 6 upwards, so that the top protective plate 5 is inside the protective cover 6. The protective cover 6 will cause the plug rod to disengage from the plug-in part 9, thus exposing the operation buttons 4 on the operation panel 3 for operation. After the operation is completed, the protective cover 6 is pulled downwards, so that the top protective plate 5 is on top of the protective cover 6, so as to reinforce the top of the protective cover 6. At the same time, the plug rod 7 is plugged into the plug-in part 9 and reinforced by the rubber snap ring 8 to ensure the stability of the connection. If the operation panel 3 is too high when the user uses the operation buttons 4, making it difficult to press the operation buttons 4, the user's arm will be strained. To prevent fatigue, the user can rotate the screw 102, which, through the threaded connection between the screw 102 and the screw sleeve 103, causes the screw 102 to move the screw sleeve 103 up and down for adjustment. The screw sleeve 103 then moves the control panel 3 to adjust for a more suitable height. During the rotation of the screw 102, the sliding engagement of the limiting block 111 and the limiting groove 112 limits the rotation of the control panel 3, preventing the screw 102 from directly rotating the screw sleeve 103 and causing the control panel 3 to rotate, thus affecting the stability of the control panel 3. When the protective plate moves up and down to open or close, the sliding engagement of the anti-detachment block 121 and the anti-detachment groove 122 prevents the protective cover 6 from moving too far and detaching from the control panel 3, further improving stability.

[0038] In summary, the button operating mechanism of this explosion-proof electrical control box, by setting up a protective cover 6, ensures that the operating buttons 4 on the control panel 3 are covered during the use of the electrical control box 1, thereby effectively preventing accidental touches. This solves the problems of numerous buttons on the explosion-proof electrical control box, which, being directly installed outside the control box without protective measures, are easily touched by personnel, affecting the operation of the electrical control box. Furthermore, the inability to easily adjust the operating height of the control buttons causes arm fatigue for shorter personnel, affecting usability.
