In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0024] See also Figure 1-6 The utility model provides a technical solution: a mechanical interlocking device for electrical equipment, including an electrical cabinet door body 1, a lock core 2, an electrical cabinet door switch 3, a main power switch 5, a plurality of control buttons 6 and two display screens 15, a push block 4 is arranged on the front side of the electrical cabinet door body 1, a connecting mechanism 7 is arranged on the front side of the push block 4, and the number of the connecting mechanisms 7 is two;

[0025] The connecting mechanism 7 includes two fixed columns 701, two swivels 702 and a connecting rod 703. The rear sides of the two top fixed columns 701 are fixedly connected to the front side of the push block 4, the bottom left fixed column 701 is fixedly connected to the front side of the main power switch 5, the rear side of the bottom right fixed column 701 is fixedly connected to the front side of the electrical cabinet door switch 3, the side of the swivel 702 close to the connecting rod 703 is fixedly connected to the connecting rod 703, and the swivel 702 is rotatably sleeved on the surface of the fixed column 701.

[0026] In this embodiment: the main power switch 5 and the electrical cabinet door switch 3 are connected by the push block 4 and the connecting rod 703. When the push block 4 is moved downward to rotate the electrical cabinet door switch 3 to open the electrical cabinet door body 1, the main power switch 5 will be forced to be in a closed state, thereby preventing illegal operators from opening the electrical cabinet door body 1 to inspect the interior of the electrical cabinet without turning off the main power switch 5. This avoids the problem that the electrical cabinet door switch 3 of most existing electrical cabinets when the electrical cabinet door body 1 is opened is not connected to the main power switch 5. When the electrical cabinet door body 1 is opened to inspect the interior of the electrical cabinet, it cannot be guaranteed that the main power switch 5 is in a closed state at this time. At this time, when operating the interior of the electrical cabinet, there is a great safety hazard.

[0027] As a technical optimization solution of the utility model, a slide groove 11 is opened inside the electrical cabinet door body 1, and a moving block 9 is fixedly connected to the rear side of the push block 4. The rear side of the moving block 9 extends to the interior of the slide groove 11 and is slidably connected to the interior of the slide groove 11.

[0028] In this embodiment, the push block 4 can be easily moved by sliding the moving block 9 inside the slide groove 11, thereby achieving the effect of facilitating the movement of the push block 4.

[0029] As a technical optimization solution of the utility model, anti-slip grooves 12 are opened on both sides of the inner wall of the slide groove 11, and anti-slip blocks 10 are fixedly connected on both sides of the moving block 9. The side of the anti-slip block 10 close to the anti-slip groove 12 extends to the interior of the anti-slip groove 12 and is slidably connected to the interior of the anti-slip groove 12.

[0030] In this embodiment: when the push block 4 moves downward, the anti-slip block 10 slides inside the anti-slip groove 12, so as to prevent the moving block 9 from being separated from the slide groove 11, so that the movement of the push block 4 is more stable, and the push block 4 is prevented from being separated from the slide groove 11, thereby achieving the effect of preventing the push block 4 from being separated from the slide groove 11.

[0031] As a technical optimization solution of the utility model, the top and bottom of the push block 4 are fixedly connected with a fixed block 16, and a limit button 13 is provided on the front side of the fixed block 16. The rear side of the limit button 13 passes through the fixed block 16 and is in close contact with the front side of the electrical cabinet door body 1, and the surface of the limit button 13 is connected to the internal thread of the fixed block 16.

[0032] In this embodiment: by rotating the limit button 13, the limit button 13 is connected to the internal thread of the fixed block 16. When the limit button 13 is rotated, the limit button 13 can be moved to be in close contact with the front side of the electrical cabinet door body 1. At this time, the friction between the anti-slip block 10 and the inner wall of the second slide groove 11 can be increased, and the anti-slip block 10 can be limited, thereby limiting the push block 4, achieving the effect of limiting the push block 4.

[0033] As a technical optimization solution of the utility model, a twist block 14 is fixedly connected to the front side of the limit button 13 , and a shift block 8 is fixedly connected to the front side of the push block 4 .

[0034] In this embodiment: by holding the screw block 14, rotating the screw block 14 can drive the limit button 13 to rotate, and by holding the shift block 8, moving the shift block 8 can move the push block 4, thereby achieving the effect of conveniently rotating the limit button 13 and moving the push block 4.

[0035] As a technical optimization solution of the utility model, the rear side of the fixing block 16 contacts the front side of the electrical cabinet door body 1, and the push block 4, the dial block 8, the twist block 14, the fixing block 16 and the limit button 13 are all made of insulating materials.

[0036] In this embodiment: since the push block 4, the shift block 8, the twist block 14, the fixed block 16 and the limit button 13 are all made of insulating materials, the push block 4, the shift block 8, the twist block 14, the fixed block 16 and the limit button 13 can be made to have an insulating function, thereby improving safety and achieving the effect of making the push block 4, the shift block 8, the twist block 14, the fixed block 16 and the limit button 13 have an insulating effect.

[0037] As a technical optimization solution of the present invention, the connecting rod 703 is made of a non-elastic material.

[0038] In this embodiment, since the connecting rod 703 is made of an inelastic material, deformation of the connecting rod 703 can be avoided, and the connecting rod 703 can drive the main power switch 5 and the electrical cabinet door switch 3 to rotate quickly and decisively, thereby avoiding deformation of the connecting rod 703.

[0039] Working principle: First, when it is necessary to open the electrical cabinet door 1 to inspect the interior of the electrical cabinet, hold the dial block 8 and pull the dial block 8 downward. At this time, the push block 4 will slide inside the slide groove 11 through the moving block 9, and the anti-slip block 10 will slide inside the anti-slip groove 12, so that the push block 4 can move downward. When the push block 4 moves downward, it can drive the connecting rod 703 to move downward. The connecting rod 703 is rotatably sleeved on the surface of the fixed column 701 through the swivel 702. The connecting rod 703 can rotatably connect the main power switch 5 and the push block 4, and the electrical cabinet door switch 3 and the push block 4, and move the push block 4 downward until the bottom of the moving block 9 contacts the bottom of the inner wall of the slide groove 11. The connecting rod 703 can push the main power switch 5 to turn downward to close and the electrical cabinet door switch 3 to turn downward to open the electrical cabinet door body 1. When the push block 4 moves downward, the anti-slip block 10 slides inside the anti-slip groove 12 to prevent the moving block 9 from disengaging from the slide groove 11, making the movement of the push block 4 more stable. After the main power switch 5 is turned downward to close and the electrical cabinet door switch 3 is turned downward to open the electrical cabinet door body 1, the bottom screw block 14 is rotated. The rotation of the screw block 14 can drive the limit button 13 to rotate. The limit button 13 is connected to the internal thread of the fixing block 16. When the limit button 13 is rotated, the limit button 13 can be moved to a position tightly connected to the front side of the electrical cabinet door body 1. The anti-slip block 10 is in close contact with the inner wall of the second slide groove 11, and the friction between the anti-slip block 10 and the inner wall of the second slide groove 11 is increased, so that the anti-slip block 10 can be limited, thereby limiting the push block 4, preventing the main power switch 5 from accidentally turning upward to open, and connecting the main power switch 5 and the electrical cabinet door switch 3 through the push block 4 and the connecting rod 703. When the push block 4 is moved downward to rotate the electrical cabinet door switch 3 to open the electrical cabinet door body 1, the main power switch 5 will be forced to be in a closed state, preventing illegal operators from opening the electrical cabinet door body 1 to inspect the inside of the electrical cabinet without turning off the main power switch 5, and avoiding the problem that the electrical cabinet door switch 3 of most existing electrical cabinets does not align with the main power switch 5 when the electrical cabinet door body 1 is opened. When the electrical cabinet door 1 is opened to inspect the interior of the electrical cabinet, it cannot be guaranteed that the main power switch 5 is in the off state. At this time, there is a great safety hazard when operating the interior of the electrical cabinet. Since the push block 4, the dial block 8, the twist block 14, the fixed block 16 and the limit button 13 are all made of insulating materials, the push block 4, the dial block 8, the twist block 14, the fixed block 16 and the limit button 13 have insulation functions to improve safety. Since the connecting rod 703 is made of inelastic material, the deformation of the connecting rod 703 can be avoided, which facilitates the connecting rod 703 to drive the main power switch 5 and the electrical cabinet door switch 3 to rotate decisively. It should be noted that the instruction manual is attached Figure 1 The main power switch 5 is in the on state and the electrical cabinet door switch 3 is in the off state.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
