Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, and in particular to an electrical cabinet with a power-off protection mechanism. Background Art

[0002] Electrical cabinets are made of steel and are used to protect components. Electrical cabinets are generally made of hot-rolled steel and cold-rolled steel. Cold-rolled steel is softer than hot-rolled steel and is more suitable for electrical cabinets. Electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] When the electrical cabinet is in use, the biggest problem is that the electrical components may have leakage. Most of the electrical cabinets on the market protect against leakage through shell insulation. Some of them also add a power-off protection structure to the electrical cabinet to avoid leakage. For example, an electrical cabinet with a power-off protection mechanism is published with announcement number CN111181031B. When the electrical components in the electrical cabinet body have leakage, the motor 1 is started, and the output shaft of the motor 1 rotates to drive the gear 1 to rotate. The rotation of the gear 1 drives the rack 1 to move. The movement of the rack 1 drives the dovetail slider 1 to slide along the slide rail. The dovetail slider works together to prevent the rack 1 from moving out. A pressing block 1 is fixed to one end of the rack 1. The movement of the rack 1 drives the pressing block 1 to move. , the pressing block presses the switch and the power is turned off, thereby preventing leakage. However, in actual use, the motor must be turned on before it can be driven to work, which is not in line with practical applications. At present, in order to avoid accidents caused by leakage, most of them use leakage protectors. By adding leakage protectors in the electrical cabinet, the power-off protection function is achieved. However, when installing the leakage protector, the wires are inserted into the installation position of the leakage protector and then tightened with bolts to press the wires. However, since the wiring harness of the wires is mostly composed of multiple copper wires, it is easy to cause the wiring harness of the wires to disperse after long-term extrusion, which makes it impossible to effectively connect and affect normal use. For this reason, we propose an electrical cabinet with a power-off protection mechanism. Summary of the invention

[0018] In this embodiment, the control part 3 includes a slip ring 31, which is slidably installed on the inner side of the mounting hole 6, a sleeve 32 is rotatably installed on the inner side of the slip ring 31, a cylinder 33 is rotatably installed on the inner side of the mounting hole 6, a spiral groove 34 and a vertical groove 35 are provided on the inner side of the cylinder 33, the spiral groove 34 and the vertical groove 35 are connected to each other, a fixing rod 36 is fixed on the inner side of the mounting hole 6, the fixing rod 36 passes through the sliding rod 37 and is slidably connected to the sliding rod 37, a connecting assembly 38 is provided on the surface of the sliding rod 37, the inner side of the cylinder 33 and the inner side of the mounting hole 6, a spiral spring 39 is fixed on the surface of the cylinder 33, and one end of the spiral spring 39 away from the cylinder 33 is fixed on the inner side of the mounting hole 6, a connecting spring 310 is fixed on the right side of the sliding rod 37, and one end of the connecting spring 310 away from the sliding rod 37 is fixed on the surface of the fixing rod 36.

[0019] Specifically, after the wire is inserted into the mounting hole 6, the wire is inserted into the sleeve 32. As the wire is pushed into the mounting hole 6, the wire moves to the right with the sleeve 32 and the slip ring 31. When the sleeve 32 abuts against the slide rod 37, the slide rod 37 is pushed to move together. The slide rod 37 passes through the connecting assembly 38, causing the cylinder 33 to rotate.

[0020] The connecting assembly 38 includes a fixing sleeve 381, which is fixed to the surface of the slide bar 37. The end of the fixing sleeve 381 away from the slide bar 37 is penetrated by the slider 382 and is slidably connected to the slider 382. A return spring 383 is fixed to the inner wall of the fixing sleeve 381. The end of the return spring 383 away from the fixing sleeve 381 is fixed to the slider 382. The end of the slider 382 away from the return spring 383 is inserted into the inner side of the spiral slide groove 34. A slot 384 is provided on one side of the slider 382. The slider 38 2 is fixed with a triangular block 385, a side surface of the fixing sleeve 381 is penetrated by a clamping rod 386 and is slidably connected with the clamping rod 386, a side surface of the fixing sleeve 381 is fixed with a spring 1 387, an end of the spring 1 387 away from the fixing sleeve 381 is fixed with the clamping rod 386, a side surface of the fixing sleeve 381 is fixed with a bracket 388, an end of the bracket 388 away from the fixing sleeve 381 is hinged with a support rod 389, an inner side of the sleeve 32 is fixed with a resisting rod 3810, and an inner side of the mounting hole 6 is fixed with a resisting block 3811.

[0021] Specifically, when the slide bar 37 is resisted and moved to the right, the slide bar 37 moves to the right with the fixed sleeve 381 and the slider 382, ​​and the slider 382 slides to the right along the spiral slide groove 34 on the inner side of the cylinder 33, causing the cylinder 33 to rotate. After the slide bar 37 moves a certain distance to the right, the slide bar 37 cannot continue to move. At this time, the resisting block 3811 resists on the triangular block 385, causing the triangular block 385 to retract into the fixed sleeve 381 with the slider 382, ​​thereby separating from the cylinder 33. At this time, the slot 384 on the side of the slider 382 moves to the position of the latch rod 386, and the latch rod 386 is inserted into the slot The slider 382 is limited in 384. When the slider 37 is no longer resisted, the slider 37 is reset to the left under the action of the connecting spring 310. When the slider 37 is completely reset with the fixing sleeve 381, the resisting rod 3810 resists on the support rod 389, so that the support rod 389 rotates at the position hinged with the bracket 388. The support rod 389 resists on the clamping rod 386, so that the clamping rod 386 moves to the side away from the slider 382, ​​thereby withdrawing from the clamping groove 384, releasing the limit on the slider 382, ​​and the slider 382 is reset under the action of the reset spring 383 and reinserted into the spiral slide groove 34.

[0022] The driven part 4 includes a ratchet disk 41, the ratchet disk 41 is fixed on the surface of the cylinder 33, a telescopic rod 42 is fixed on the inner side of the mounting hole 6, a pawl 43 is provided on the side of the telescopic rod 42 close to the ratchet disk 41, a spring 2 44 is fixed on the surface of the telescopic rod 42, one end of the spring 2 44 away from the telescopic rod 42 is fixed on the inner side of the mounting hole 6, a connecting rod 45 is hinged on the left side of the telescopic rod 42, one end of the connecting rod 45 away from the telescopic rod 42 is hinged on the right side of a moving rod 46, and the moving rod 46 is slidably installed on the inner side of the mounting hole 6.

[0023] Specifically, the pawl 43 can be stuck on the ratchet disk 41, so that the cylinder 33 can only rotate in one direction. When the slide rod 37 moves to the right and drives the cylinder 33 to rotate through the control slider 382, ​​the cylinder 33 reels the spiral spring 39, and under the action of the ratchet disk 41 and the pawl 43, the cylinder 33 cannot rotate in the opposite direction. When the slip ring 31 moves a certain distance to the right, the slip ring 31 can contact the moving rod 46, so that the moving rod 46 moves to the right. The moving rod 46 pulls the telescopic rod 42 to shorten through the connecting rod 45. The telescopic rod 42 separates from the ratchet disk 41 with the pawl 43, and the cylinder 33 can rotate in the opposite direction.

[0024] A clamping assembly 5 is provided on the right side and inside of the sleeve 32, and the clamping assembly 5 includes a turntable 51, which is rotatably installed on the right side of the sleeve 32, an arc groove 52 is provided on the left side of the turntable 51, and a guide groove 53 is provided on the right side of the sleeve 32. A guide rod 54 is slidably installed on the inner side of the guide groove 53, one end of the guide rod 54 is fixed to the clamping block 55, and the other end of the guide rod 54 is inserted into the inner side of the arc groove 52.

[0025] Specifically, when the turntable 51 rotates, since the guide rod 54 is limited by the guide groove 53, the guide rod 54 can only slide along the guide groove 53. The turntable 51 can contact the guide rod 54 through the arc groove 52 provided therein, so that the guide rod 54 slides along the guide groove 53, thereby driving the clamping block 55 to clamp the wire harness inserted into the sleeve 32.

[0026] An embedding groove 7 is provided on the right side of the rotating disk 51 , and a pushing block 8 is fixed on the surface of the cylinder 33 .

[0027] Specifically, when the sleeve 32 moves the turntable 51 to the right and the turntable 51 contacts the cylinder 33, the pushing block 8 on the surface of the cylinder 33 is in the embedding groove 7 on the right side of the turntable 51. When the cylinder 33 rotates, the cylinder 33 can push against the inner wall of the embedding groove 7 through the pushing block 8, thereby driving the turntable 51 to rotate together. When the turntable 51 cannot rotate, it can drive the sleeve 32 to rotate together, thereby tightening the wire harness inserted into the sleeve 32 to ensure a stable connection between the wire harness and the leakage protector 2.

[0028] A fastening assembly 9 is provided at the wiring point of the leakage protector 2, and the fastening assembly 9 includes a fixing frame 91, which is fixed at the wiring point of the leakage protector 2. A circular hole 92 is opened in the center of the fixing frame 91, and the fixing frame 91 is penetrated by a screw 93 and is threadedly connected to the screw 93. A rubber plate 94 is rotatably installed on the side of the screw 93 close to the center of the circular hole 92. By rotating the screw 93, the rubber plate 94 can be moved to the side close to the center of the circular hole 92 or the side away from the center of the circular hole 92, so as to tighten the wires connected to the leakage protector 2 and ensure the stability of the connection.

[0029] Based on the above embodiment, when wiring the leakage protector 2 , the corresponding wires are inserted into the corresponding mounting holes 6 on the leakage protector 2 .

[0030] When the wire is inserted into the mounting hole 6, the wire is inserted into the sleeve 32. As the wire is pushed into the mounting hole 6, the wire moves to the right with the sleeve 32 and the slip ring 31. When the sleeve 32 abuts against the slide bar 37, the slide bar 37 is pushed to move together. At this time, the slide bar 37 moves to the right with the fixing sleeve 381 and the slider 382. The slider 382 slides to the right along the spiral slide groove 34 on the inner side of the cylinder 33, causing the cylinder 33 to rotate. After the slide bar 37 moves a certain distance to the right, the slide bar 37 cannot continue to move. At this time, the abutment block 3811 abuts against the triangular block 385, causing the triangular block 385 to retract the slider 382 into the fixing sleeve 381, thereby separating from the cylinder 33. At this time, the slot 384 on the side of the slider 382 moves to the position of the clamping rod 386, and the clamping rod 386 is inserted into the slot 384 to limit the slider 382.

[0031] When the sleeve 32 moves the turntable 51 to the right, the turntable 51 and the cylinder 33 contact each other, and the pushing block 8 on the surface of the cylinder 33 is in the embedding groove 7 on the right side of the turntable 51. When the slip ring 31 moves to the right for a certain distance, the slip ring 31 can abut on the moving rod 46, so that the moving rod 46 moves to the right. The moving rod 46 shortens the telescopic rod 42 through the connecting rod 45, and the telescopic rod 42 separates from the ratchet disc 41 with the pawl 43, and the cylinder 33 can rotate in the opposite direction. The cylinder 33 rotates in the opposite direction under the action of the spiral spring 39, and the cylinder 33 drives the turntable 51 to rotate together through the pushing block 8 against the inner wall of the embedding groove 7. When the cylinder 33 rotates, the cylinder 33 can push the block 8 to contact the inner wall of the embedded groove 7 to drive the turntable 51 to rotate together. When the turntable 51 cannot rotate, the sleeve 32 can be driven to rotate together, so as to tighten the wire harness inserted into the sleeve 32 to ensure the stable connection between the wire harness and the leakage protector 2. By rotating the screw 93, the rubber plate 94 can be moved to the side close to the center of the circular hole 92 or away from the center of the circular hole 92 to tighten the wires connected to the leakage protector 2 to ensure the stability of the connection. The leakage protector 2 is screwed in with a screw to compress the wire harness to complete the connection with the wire harness.

[0032] When leakage occurs, the leakage protector 2 can start working to cut off the power supply, thus playing the role of power-off protection.

[0033] When it is necessary to remove the wire, just unscrew the screw, and the control screw 93 drives the rubber plate 94 to loosen the fixation of the wire, and pull the wire out of the mounting hole 6. At this time, since the clamping block 55 is in the state of clamping the wire, the wire moves with the sleeve 32 and the slip ring 31, so that it no longer conflicts with the slide bar 37. Under the action of the connecting spring 310, the slide bar 37 is reset to the left. When the slide bar 37 is fully reset with the fixing sleeve 381, the conflicting rod 3810 conflicts with the support rod 389, so that the support rod 389 rotates at the position hinged with the bracket 388, and the support rod 389 conflicts with the clamping rod 386, so that the clamping rod 386 moves to the side away from the slider 382, ​​so as to withdraw from the slot 384, release the limit of the slider 382, ​​and the slider 382 is reset under the action of the reset spring 383, and reinserted into the spiral slot 34, and the wire can be taken out, which is convenient to use.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
