Description

Pneumatic switch Technical Field The utility model relates to the field of electromechanical equipment, in particular to a pneumatic switch. Background The ventilation work is the key work of the safety production in various fields, particularly the working environment such as underground, and the working surface depends on the air supply and return of the air duct. With the progress and development of technology, ventilation equipment such as an air duct air-separating and dust-controlling system and other equipment disclosed in China patent 2024202091377 can realize auxiliary functions such as air separation, dust collection and the like in the ventilation process through multi-equipment linkage during operation. However, the control of the relevant electromechanical device is dependent on manual triggering or coordinated control triggering by a system, and there is no mechanical trigger switch like a travel switch, that is, a mechanical switch powered by wind power. The electromechanical equipment which causes linkage has operation hidden troubles such as untimely triggering and the like. There is currently no corresponding solution to this problem. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the pneumatic switch which has the advantages of simple structure and flexible assembly and can respond to the air supply or return state to trigger or link the electromechanical equipment. The device comprises an air bearing plate, wherein the air bearing plate is a panel member for receiving wind blowing; The wind-supporting plate is hinged on the machine body shell through a connecting rod, and a trigger switch is arranged in the machine body shell corresponding to the rotating stroke of the connecting rod. The effect that realizes with this is that the windward board rotates along its pin joint when accepting the windward, and based on trigger switch setting position and its rotation stroke correspondence, trigger switch is triggered. The utility model has the beneficial effects that a blank in the prior art is made up by a simple structure, the wind power mechanical trigger switch is realized, the wind power mechanical trigger switch is suitable for being arranged in ventilation equipment, and wind power trigger single equipment or multi-equipment linkage is realized by responding to the wind power. Drawings FIG. 1 is a schematic view of an air operated switch according to the present utility model; FIG. 2 is a schematic cross-sectional view of a pneumatic switch according to the present utility model; FIG. 3 is a schematic cross-sectional view from the top, and also from 3; reference numerals: 1-a machine body shell 2-a wind-supporting plate 3-a trigger rod 4-a return elastic body 5-a limit baffle 6-an assembly cavity 7-a connecting rod 71-a hinged connecting section 72-a panel connecting section 8-a trigger switch 9-a spring piece The achievement of the objects, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings, in conjunction with the embodiments. Detailed Description Referring to fig. 1 and 2, the pneumatic switch of the utility model comprises a wind-supporting plate 2, wherein the wind-supporting plate 2 is a panel member for receiving wind blowing; The wind-supporting plate 2 is hinged on the machine body shell 1 through a connecting rod 7, and a trigger switch 8 is arranged in the machine body shell 1 corresponding to the rotation travel of the connecting rod 7. The effect achieved in this way is that the wind-supporting plate 2 rotates along its hinge point when receiving wind flow, and the trigger switch 8 is triggered based on the setting position of the trigger switch 8 corresponding to the rotation travel thereof. In embodiment 1, the connecting rod 7 is of a split structure and comprises a hinged connection section 71 hinged in the machine body shell 1, a panel connection section 72 is arranged below the hinged connection section 71, and the wind-bearing plate 2 is fixedly arranged on the panel connection section 72. Further, the panel connecting section 72 is hinged or connected with the hinged connecting section 71 in a plugging manner.
