[0019] Embodiment 1

[0020] Please refer to Figures 1-3 , a kind of automatic drawing-in machine pneumatic control switch device in the figure, including control switch body 101 and the air inlet hole 102 and two air outlet holes 103 of setting in the opposite two side walls of control switch body 101, still including the mounting pipe 2 of setting in the side wall of control switch body 101, mounting pipe 2 with the internal gas circuit of control switch body 101 is communicated and is set, mounting pipe 2 is equipped with the component for controlling the internal gas pressure of control switch body 101 and the detection component for the detection of the internal sealing of control switch body 101 is set in control component;

[0021] Control component includes the control plate 3 of setting in mounting pipe 2, control plate 3 side wall is equipped with the connecting component for being sealed with mounting pipe 2 Connection, mounting pipe 2 is equipped with the telescopic component for the telescopic of control plate 3;

[0022] It needs to be explained here: through the setting of control component, under the action of telescopic component, for when local gas leakage occurs in control switch body 101, ensure the pressure of the internal gas of control switch body 101, to further ensure the driving of piston to valve, electric appliance and other mechanical connecting pieces, in turn, ensure the continuity of the various actions control of automatic drawing-in machine pneumatic, simultaneously, under the action of detection component, it is convenient for staff to find the gas leakage problem of control switch body 101 and carry out corresponding processing in time.

[0023] It is worth noting that: control switch body 101 as prior art, its specific structure and working principle has been mastered by the person skilled in the art, here is not too much elaboration.

[0024] Please refer to Figure 2 andFigure 3 The connecting assembly in the drawing includes an annular sealing groove 401 opened in the side wall of the control plate 3, and the annular sealing groove 401 is provided with an annular sealing rubber ring 402;

[0025] It should be noted that the connecting assembly is arranged to ensure the sealing connection between the control plate 3 and the inner wall of the mounting pipe 2.

[0026] Please refer to Figure 2 and Figure 3 The telescopic assembly in the drawing includes a telescopic pipe 501 fixedly connected to the inner wall of the mounting pipe 2 away from the control switch body 101, the telescopic pipe 501 is slidingly connected with a telescopic rod 502, one end of the telescopic rod 502 is connected with the control plate 3, the other end of the telescopic rod 502 is located in the telescopic pipe 501, and the telescopic plate 503 is fixedly connected, the first spring 504 is arranged on the side of the telescopic plate 503 away from the telescopic rod 502, and the other end of the first spring 504 is connected with the bottom wall of the telescopic pipe 501.

[0027] It should be noted that the telescopic assembly is arranged to provide guidance and elastic extrusion pushing action for the movement of the control plate 3.

[0028] Working principle: when the control switch body 101 is in use, when external high-pressure air enters the control switch body 101, the air will enter the air path system of the switch through the air inlet, and when the pressure sensor installed in the air path system detects the preset pressure value, it will send a control signal to activate the switch. Once the switch is activated, the compressed air will be transmitted to the piston through the air path system, which will cause the piston to start moving, thereby driving the mechanical connecting member such as a valve, an electric appliance, etc. to switch its state, thereby changing the working state of the switch.

[0029] And when the state of the valve, the electric appliance, etc. is maintained, the compressed gas needs to be kept in the control switch body 101 to maintain the pressure state, so as to realize the continuous pushing force of the piston. Therefore, under the action of the high-pressure gas in the control switch body 101, the control plate 3 will be pushed to slide in the mounting pipe 2. At this time, the telescopic assembly will generate elastic force under the extrusion action.

[0030] When the control switch body 101 is in a high pressure state for a long time, the sealing element at the connection of the control switch body 101 will increase the risk of gas leakage due to high pressure. When gas leakage occurs at the connection of the control switch body 101, the elastic effect of the telescopic assembly will exert a reverse elastic pushing force on the control plate 3, so that the control plate 3 extrudes the gas in the control switch body 101, thereby ensuring the pressure of the gas in the control switch body 101, further ensuring the driving of the piston on the valve, the electric appliance and other mechanical connecting elements, thereby maintaining the working state of the valve, the electric appliance and other mechanical connecting elements, and further ensuring the control of various actions of the automatic threading machine. Under the action of the detection assembly, the worker can timely find the gas leakage problem of the control switch body 101 and perform corresponding processing.

[0031] Embodiment 2

[0032] Referring to Figure 3 , the embodiment further illustrates embodiment 1.

The detection pipe 601 is provided with a support assembly for supporting the detection plate 602.

[0033] It should be noted that the detection assembly is provided to facilitate the worker to timely find the gas leakage problem of the control switch body 101 and perform corresponding processing.

[0034] Referring to Figure 2 and Figure 3 , the support assembly in the figure includes a cross plate 701 fixedly connected to the inner wall of the detection pipe 601. The cross plate 701 is slidably connected with a support rod 702. One end of the support rod 702 is connected with the detection plate 602.

The control plate 3 is provided with a pushing assembly for pushing the support rod 702.

[0035] It should be noted that the support assembly is provided to provide elastic support for the detection plate 602.

[0036] Referring to Figure 2 and Figure 3 Figure 2 Figure 3 , the pushing assembly in the figure is a slope 8 opened in the opposite two side walls of the control plate 3.

[0037] It should be noted that the slope 8 is provided to push the support rod 702.

[0038] Working principle: when the external high pressure gas enters into the control switch body 101, the control switch body 101 inside pushes the control plate 3 to move in the installation pipe 2, in the process of the control plate 3 moving, when the control plate 3 abuts against the support rod 702, the detection plate 602 at one end of the support rod 702 will be pushed to move away from the installation pipe 2 under the interaction force of the inclined plane 8, when the pressure in the control switch body 101 is in the pressure maintaining state, the distance sensor 603 is used to measure the distance of the position of the detection plate 602;

[0039] When the control switch body 101 appears partial gas leakage, the pressure in the control switch body 101 will decrease, at this time, under the elastic action of the telescopic assembly, the control plate 3 will be pushed to move close to the control switch body 101, and then the pushing force to the support rod 702 is reduced, at this time, under the elastic action of the second spring 703, the detection plate 602 will be driven to move away from the distance sensor 603, when the distance sensor 603 detects that the moving distance of the detection plate 602 exceeds the set threshold, an electric signal will be sent to the controller, and then under the analysis and processing of the controller, the warning information will be sent to the worker, so that the worker can find the gas leakage problem of the control switch body 101 in time and carry out corresponding processing.
