[0002] A control cabinet is an electrical device. For complex control circuits, a large number of control switch units need to be installed centrally to facilitate automatic control or manual control. In order to improve the convenience and safety of using control switches, control cabinets are used. Complex circuits and switch units are installed in the control cabinet in an orderly manner, which not only protects the circuits but also facilitates maintenance and repair.

[0003] In actual use, most existing control cabinets use rotary locks to lock the cabinet doors. The structure is simple, which can not only ensure that the cabinet door and the control cabinet are firmly locked, but also facilitate the opening of the cabinet door. However, when opening the cabinet door, you need to hold the key to turn the rotary lock. If the switch cabinet is not in the power-off state, opening the cabinet door rashly will increase the risk of electric shock. Therefore, the cabinet door will be opened due to accidental release, which will obviously reduce the safety factor when the switch cabinet is used.

[0004] In view of this, the present application proposes a control cabinet anti-accidental touch release mechanism that can prevent the risk of electric shock and improve the safety factor. Summary of the invention

[0032] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Example

[0034] like Figure 1-Figure 4As shown, the utility model proposes a control cabinet anti-mistouch release mechanism, including a lock cover plate 1, on which a control component protection cover 2 and a lock protection cover 5 are fixedly installed, and a control circuit board 8 and a servo motor 9 are fixedly installed inside the above-mentioned control component protection cover 2. When the power inside the switch cabinet is cut off, the control circuit board 8 serves as a control unit to make the servo motor 9 enter a rotating state. In this state, the storage battery 10 fixed inside the control component protection cover 2 supplies power to the servo motor 9 to ensure that the servo motor 9 can operate normally after the internal circuit of the switch cabinet is cut off; a lifting regulator 7 is installed inside the control component protection cover 2, and the above-mentioned servo motor 9 and the lifting regulator 7 are fixedly installed inside the above-mentioned servo motor 9 and the lifting regulator 7. The adjuster 7 is in a meshing connection relationship, and then can drive the lifting adjuster 7 to move in the vertical direction; a rotary lock 6 is fixedly installed on the lock cover plate 1. When the lock cover plate 1 is fixed on the cabinet door of the switch cabinet, the above-mentioned rotary lock 6 serves as a locking structure of the cabinet door, and the lock hole end of the rotary lock 6 covers the inside of the lock protective cover 5. The bottom of the above-mentioned lifting adjuster 7 is fixedly installed with an anti-accidental touch baffle 3. When the internal circuit of the switch cabinet is in a power-on state, the bottom of the anti-accidental touch baffle 3 is inserted into the lock protective cover 5. At this time, the circular unlocking window 4 opened on the lock protective cover 5 is blocked by the anti-accidental touch baffle 3, so that the lock hole of the rotary lock 6 cannot be inserted with a key to unlock it.

[0035] Furthermore, the lifting regulator 7 is composed of a fixed frame plate 71, a pressure sensor 72, a limit rod 73, a lifting plate 74, a pressure probe rod 75 and a reciprocating screw rod 76. The above-mentioned fixed frame plate 71 is fixed on the lock cover plate 1, the limit rod 73 is fixed between the inner bottom wall of the control component protective cover 2 and the fixed frame plate 71, and the reciprocating screw rod 76 is rotatably installed between the inner bottom wall of the control component protective cover 2 and the fixed frame plate 71. There are at least two of the above-mentioned limit rods 73, and the lifting plate 74 is movably mounted on a plurality of limit rods 73, and the reciprocating screw rod 76 passes through the lifting plate 74 and is threadedly connected thereto. When the reciprocating screw rod 76 rotates, the limit rod 73 limits the lifting plate 74 in the horizontal direction to ensure its stable lifting and lowering movement, which can then drive the anti-mistaken touch baffle 3 fixed at the bottom of the lifting plate 74 to stably lift and lower.

[0036] Secondly, a second bevel gear 91 is fixedly installed on the output end of the servo motor 9, and a first bevel gear 761 is fixedly installed on the reciprocating screw 76. The above-mentioned first bevel gear 761 is meshed and connected with the second bevel gear 91. When the servo motor 9 enters the operating state, its output shaft can drive the reciprocating screw 76 to rotate, thereby ensuring the stability of the lifting and lowering movement of the lifting plate 74.

[0037] Furthermore, the above-mentioned pressure sensor 72 is fixed on the lower surface of the fixed frame plate 71, and the pressure sensor 72 is electrically connected to the control circuit board 8. A plurality of pressure probe rods 75 are fixed on the upper surface of the lifting plate 74. When the lifting plate 74 moves upward for a certain distance and the top of the pressure probe rod 75 touches the pressure sensor 72, the pressure sensor 72 transmits the received signal to the control circuit board 8, and then stops the servo motor 9 to prevent the anti-mistaken touch baffle 3 from being lifted to the highest position and then moving down quickly. When the staff inserts the key from the circular unlocking window 4 to unlock the door, the hand can be prevented from being pinched by the baffle.

[0038] It is worth mentioning that a circular docking groove 751 is bored on the top of the pressure probe 75, a circular docking column 752 is inserted at the notch of the circular docking groove 751, and a spring 754 is fixedly installed between the bottom of the circular docking groove 751 and the circular docking column 752, so that the circular docking column 752 can perform telescopic movement within the restricted range of the circular docking groove 751, and a rubber column head 753 is fixedly installed on the top of the circular docking column 752. After the pressure probe 75 contacts the pressure sensor 72, the rubber column head 753 can prevent indentations from being generated on the pressure sensor 72, and in the process of the spring 754 entering the compression state, it can prevent the pressure probe 75 from having hard contact with the pressure sensor 72, thereby improving the protection effect of the pressure sensor 72.

[0039] In this embodiment, first, when the internal circuit of the switch cabinet is in the power-on state, the servo motor 9 enters the non-operating state. At this time, the anti-accidental touch baffle 3 cannot move and is blocked in front of the lock hole of the rotary lock 6, and then the staff cannot use the key to unlock the rotary lock 6; when the internal circuit of the switch cabinet is in the power-off state, the control circuit board 8 receives the power-off signal and the battery 10 supplies power to the circuit board and the servo motor 9. At this time, the control unit installed on the control circuit board 8 can command and control the servo motor 9 to enter the operating state; the reciprocating screw rod 76 is driven to rotate by the servo motor 9, and then the lifting plate 74 can be driven to move upward. Since the anti-accidental touch baffle 3 is fixedly connected to the lifting plate 74 as a whole, the anti-accidental touch baffle 3 can move upward with the lifting plate 74. When the lock hole of the rotary lock 6 is no longer covered by the anti-accidental touch baffle 3, the staff can use the key to unlock the rotary lock 6 from the circular unlocking window 4. The anti-accidental touch release mechanism can eliminate the problem of accidents caused by human operating errors, avoid the risk of electric shock caused by human accidental touch to open the control cabinet, and effectively improve the safety factor of the control cabinet when in use.

[0040] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
