However, the current power switches are usually knife switches or air switch gate valves, and their closing mechanisms are just simple mechanical mechanisms. The gate valve can be closed or closed by pushing or pulling. Especially in the work area or living area where there are many people, in this case, there is no on-duty personnel, the on-duty personnel leave the post or the safety sign falls, and special situations such as the risk of accidental closing are very likely to occur, and safety accidents caused by this are also common.

[0016] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model discloses a circuit assembly anti-closing mechanism, comprising a housing 1, wherein the housing 1 comprises a front panel, and two opposite side panels 5 are integrally connected to both sides of the front panel;
[0018] A screw hole is provided on one side panel 5, a screw rod 4 is passed through the screw hole, a safety slot 43 is provided in the middle of the screw rod 4, and a gasket 42 is provided at one end of the screw rod 4;
[0019] A base 3 is fixedly arranged on the side panel 5 above the screw hole. A positioning hole 31 is opened on the base 3. A positioning pin 2 is passed through the positioning hole 31. A locking hole 21 is also arranged at the bottom of the positioning pin 2.
[0020] The effect achieved in this way is that the shell 1 covers the front of the switch, the screw 4 is rotated to make the gasket 42 press against the switch housing, that is, the shell 1 is fixed on the switch as a whole, the positioning pin 2 is passed through the positioning hole 31 and the safety slot 43 in sequence, and finally the mechanical lock is hung in the lock hole 21. The positioning pin 2 cannot be pulled out, that is, the screw 4 cannot rotate in this state, so that the shell 1 is always covered on the switch panel, and the effect of preventing the switch from closing is achieved.
[0021] Furthermore, the side panel 5 is wider at the top and narrower at the bottom, and is chamfered at the corners.
[0022] The effect achieved thereby is to make the device more suitable for knife gate valves, that is, to fit the housing of knife gate valves more closely.
[0023] Furthermore, the safety slot 43 is in the form of a long through slot opened on the rod body of the screw rod 4 .
[0024] Preferably, the screw rod 4 has fine and dense teeth.
[0025] Furthermore, the positioning pin 2 is in the form of a vertically bent curved rod, and its outer diameter is smaller than the safety slot 43 .
[0026] The effect achieved in this way is that, corresponding to the position of the positioning hole 31, during the process of the screw 4 rotating one circle, there are at least two locking positions that are convenient for the positioning pin 2 to pass through, and because the outer diameter of the positioning pin 2 is smaller than the safety slot 43, the constraint on the final rotation angle of the screw 4 is extremely low, thereby achieving the effect of facilitating the passing of the positioning pin 2.
[0027] Furthermore, a hand-tightening sleeve 41 is provided at one end of the screw rod 4, and a gasket 42 is rotatably provided at the other end.
[0028] Preferably, the screw rod 4 is rotatably provided with a gasket 42 via a bearing.
[0029] Furthermore, the gasket 42 is a rubber gasket 42, and anti-skid patterns or anti-skid particles are arranged on the outer surface thereof.
[0030] Furthermore, an anti-closing mark is provided on the front of the housing 1.
[0031] When the utility model is used, the shell 1 covers the front of the switch, and the switch mentioned here includes an independent switch blade and an air switch arranged in a row. When corresponding to the air switches arranged in a row, one side panel 5 is inserted into the gap between the multiple air switches, and the other side panel 5 blocks the end of the row of air switches;
[0032] The screw rod 4 is rotated to make the gasket 42 press against the switch housing, that is, the housing 1 is fixed on the switch as a whole, and the positioning pin 2 is passed through the positioning hole 31 and the safety slot 43 in sequence, and finally the mechanical lock is hung in the lock hole 21. The positioning pin 2 cannot be pulled out, that is, the screw rod 4 cannot rotate in this state, so that the housing 1 is always covered on the switch panel, thereby achieving the effect of preventing the switch from being closed.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
