Description

Technical Field

[0001] The utility model relates to the field of electromechanical equipment, in particular to a pneumatic switch. Background Art

[0002] Ventilation work is a key task for safe production in various fields. Specifically, in working environments such as underground, the working face depends on air ducts for air supply and return. With the progress and development of technology, ventilation equipment such as a duct air distribution and dust control system disclosed in Chinese Patent No. 2024202091377 can, during operation, through the linkage of multiple devices, achieve auxiliary functions such as air distribution and dust collection during ventilation.

[0003] However, the control of related electromechanical equipment still relies on manual triggering or collaborative control triggered by the system, and there is no mechanical trigger switch such as a travel switch, that is, a mechanical switch triggered by wind force. This results in potential operation hazards such as untimely triggering for the linked electromechanical equipment. Currently, there is still a lack of corresponding solutions to this problem. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a pneumatic switch with a simple structure, flexible assembly, capable of responding to the air supply or return state, and triggering or联动触发 electromechanical equipment.

[0005] The device includes a wind-receiving plate, which is a panel component that receives the wind.

[0006] The wind-receiving plate is articulated to the body shell through a connecting rod. Corresponding to the rotation stroke of the connecting rod, a trigger switch is also arranged inside the body shell.

[0007] The effect achieved thereby is that when the wind-receiving plate receives the wind current, it rotates along its hinge point, and based on the position of the trigger switch corresponding to its rotation stroke, the trigger switch is triggered.

[0008] The beneficial effect of the utility model is that the utility model fills a gap in the prior art with a simple structure, realizes a wind-force mechanical trigger switch, which is suitable for being arranged inside ventilation equipment, and responds to the air supply and return to achieve single-device or multi-device linkage triggered by wind force.

[0014] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0015] Reference Figure 1 , Figure 2 The wind-operated switch of this utility model includes a wind-receiving plate 2, which is a panel component that receives wind.

[0016] The air-bearing plate 2 is hinged to the outer shell 1 of the machine body via a connecting rod 7. A trigger switch 8 is also provided inside the outer shell 1 to correspond to the rotation stroke of the connecting rod 7.

[0017] The effect achieved is that when the air receiving plate 2 receives airflow, it rotates along its hinge point, and the position of the trigger switch 8 corresponds to its rotation stroke, and the trigger switch 8 is triggered.

[0018] In Example 1, the connecting rod 7 is a split structure, including a hinged connecting section 71 hinged inside the outer shell 1 of the machine body, a panel connecting section 72 is provided below the hinged connecting section 71, and the air-bearing plate 2 is fixedly installed on the panel connecting section 72.

[0019] Furthermore, the panel connecting section 72 and the hinge connecting section 71 are hinged or plugged in.

[0020] The effect achieved is that the panel area and orientation of the wind-bearing plate 2 can be flexibly adjusted according to the wind force and airflow direction.

[0021] In Example 2, a trigger rod 3 is slidably disposed inside the outer casing 1 of the machine body. The tail end of the trigger rod 3 is set to correspond to the rotation stroke of the connecting rod 7, and its end is set to correspond to the trigger switch 8.

[0022] Furthermore, the outer casing 1 of the machine body is provided with an assembly cavity 6, and the trigger rod 3 is slidably disposed in the assembly cavity 6;

[0023] A limiting baffle 5 is integrally provided on the trigger rod 3, and a return elastic body 4 is provided between the limiting baffle 5 and the assembly cavity 6.

[0024] Furthermore, the return elastic body 4 is a spring.

[0025] The limiting baffle 5 mentioned here is a baffle set in the inner cavity of the assembly cavity 6. Its outer diameter is larger than that through which the trigger rod 3 passes. The assembly hole is set in the assembly cavity; that is, it serves to prevent the trigger rod 3 from being out of position. The return spring is set between the limiting baffle 5 and the front of the inner cavity of the assembly cavity 6. The front here refers to the direction of the trigger switch 8 being forward.

[0026] The effect achieved is that the wind-bearing plate 2 automatically returns to its original position when there is no wind, thanks to the return spring.

[0027] In Example 3, a spring sheet 9 is also provided on the side of the trigger switch 8.

[0028] The effect achieved is that the trigger rod 3 is set at the tail end of the spring plate 9, which provides the trigger rod 3 with a limit stroke. That is, when the wind force is large, the trigger rod 3 will only press against the spring plate 9 and the outer shell of the trigger switch 8, and will not directly press against the button or response part of the switch, causing the button or response part to be damaged due to excessive pressure.

[0029] In Example 4, the trigger switch 8 is connected to a wireless signal transceiver.

[0030] The effect achieved is that the signal responds instantly after the switch is triggered, and multiple devices can be linked through wireless transmission and reception.
