Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an air-release and electrically controlled synchronous switch. Background Art

[0002] For some places with high airtightness requirements, airtight doors are installed. After the airtight door is closed, the sealing strip needs to be filled to seal the edge of the airtight door to ensure that the gas in the room does not leak out. The airtight door generally uses a controller to control the inflation / deflation and door locking / unlocking. In the event of an emergency due to a control system failure, internal personnel need to urgently release the gas from the airtight door sealing strip through the deflation switch and release the access control through the electric control switch before they can open the airtight door to evacuate. However, the existing deflation switch and electric control switch are executed independently, so it is necessary to operate both switches in succession before evacuating, which increases the risk of people indoors in an emergency.

Specific embodiments

[0021] The following further describes the specific embodiments of the present utility model in conjunction with the drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As Figures 1-5 shown, 1. An air release and electric control synchronous switch, comprising a button housing 1, an integral button 2, an air release switch module 3 and a key switch 4; the integral button 2 is arranged at the first end of the button housing 1 and is slidably connected to the button housing 1; an exhaust hole 11 is formed on the wall surface of the button housing 1;

[0023] Both the air release switch module 3 and the key switch 4 are arranged in the button housing 1, the output end of the air release switch module 3 faces the second end of the button housing 1, and both the air release driving part 31 of the air release switch module 3 and the key part 41 of the key switch 4 face the integral button 2, so as to use the integral button 2 to synchronously drive the air release switch module 3 to move towards the second end of the button housing 1 and press the key part 41 of the key switch 4, and make the output end of the air release switch module 3 extend out of the button housing 1 and make the key switch 4 disconnect the circuit.

[0024] In the air release and electronically controlled synchronous switch, after the integrated button 2 is pressed, the integrated button 2 can simultaneously act on the air release driving part 31 of the air release switch module 3 and the button part 41 of the key switch 4, thereby driving the output end of the air release switch module 3 to extend outside the button housing 1, and realizing the action of the button part 41 of the key switch 4, so that the output end of the air release switch module 3 is inserted into the air pipe 6 located outside the button housing 1, conducting the air pipe 6. The gas of the airtight door sealing strip can enter the button housing 1 through the air pipe 6 and the output end of the air release switch module 3, and then be discharged through the exhaust hole 11 on the button housing 1, and the button part 41 of the key switch 4 is pressed to achieve the purpose of disconnecting the circuit, unlocking the airtight door electrolytically, and this action is realized synchronously. In this way, when applied to an airtight space, air release and electrolytic unlocking and opening of the airtight door can be achieved simultaneously, so that indoor personnel can quickly evacuate in an emergency and ensure the safety of indoor personnel.

[0025] It should be noted that, as Figure 3 shown, it further includes a return spring 5. The return spring 5 is arranged inside the button housing 1, and the first end of the return spring 5 is connected to the integrated button 2, and the second end of the return spring 5 is connected to the inner wall of the button housing 1. After the integrated button 2 is pressed, the integrated button 2 will apply a force to the return spring 5 to compress the return spring 5. After the integrated button 2 is released, the compression spring force of the return spring 5 can be used to reset the integrated button 2.

[0026] Preferably, as Figure 4 and 5 shown, the air release switch module 3 includes an air release insertion tube 32, a first switch housing 33, a baffle 34, a plug 35 and an air release button 36;

[0027] The air release insertion tube 32 is arranged at the output end of the air release switch module 3 and is communicated with the inside of the first switch housing 33; the first switch housing 33 is slidably connected to the button housing 1;

[0028] A baffle 34 is arranged inside the first switch housing 33 to divide the inside of the first switch housing 33 into an input chamber 341 and an output chamber 342. An air release port 331 is opened on the inner wall of the first switch housing 33 located in the output chamber 342, and a through hole 343 is opened in the center of the baffle 34; in this embodiment, the air release insertion tube 32 is communicated with the input chamber 341;

[0029] The first end of the plug 35 passes through the through hole 343 from the output cavity 342 towards the input cavity 341. The second end of the plug 35 is connected to the first end of the air release driving part 31. An insertion port is provided at the end of the first switch housing 33 away from the air release insertion tube 32. The air release driving part 31 is arranged in the insertion port so that the air release driving part 31 is slidably connected to the first switch housing 33. The air release button 36 is arranged outside the first switch housing 33 and is connected to the second end of the air release driving part 31. The air release button 36 faces the integrated button 2.

[0030] After pressing the integrated button 2, the integrated button 2 acts on the air release button 36, pushing the air release button 36 to move downward. Thus, the plug 35 is driven to move downward through the air release driving part 31. A sealing gasket 351 is provided at the first end of the plug 35. Before moving downward, the sealing gasket 351 is tightly attached to the baffle 34 to block the through hole 343. After the plug 35 moves downward, the sealing gasket 351 leaves the baffle 34, and the through hole 343 can communicate with the input cavity 341. In this way, the air release insertion tube 32, the input cavity 341, the through hole 343, the input cavity 341, and the air release port 331 are sequentially communicated. At this time, the air release button 36 will abut against the first switch housing 33. When the integrated button 2 continues to push the air release button 36 downward, the first switch housing 33 can be pushed to move downward, thereby driving the air release insertion tube 32 to move downward and extend out of the button housing 1 and insert into the air tube 6. Specifically, the air tube 6 is in a closed state before the air release insertion tube 32 is inserted. After the air release insertion tube 32 is inserted into the air tube 6, the air tube 6 can be conducted. This technology is prior art and will not be elaborated here again. In this embodiment, the air tube 6 is communicated with the space inside the airtight door sealing strip. After the air tube 6 is conducted, the airtight door sealing strip can be deflated.

[0031] Optionally, the air release switch module 3 further includes a telescopic spring 37. The telescopic spring 37 is sleeved on the outer wall of the plug 35, and the first end of the telescopic spring 37 is connected to the baffle 34, and the second end of the telescopic spring 37 is connected to the first end of the air release driving part 31. When the air release driving part 31 moves downward, the telescopic spring 37 will be compressed. After the air release driving part 31 loses the downward thrust, the spring force of the telescopic spring 37 can be used to push the air release driving part 31 and the air release button 36 to reset.

[0032] Specifically, a sealing ring 321 is sleeved on the outer wall of the air release insertion tube 32. In this way, after the air release insertion tube 32 is inserted into the air tube 6, it is not easy to leak air.

[0033] It is worth noting that, asFigure 1 and 2 As shown in 2 , the push-button switch 4 is a normally open switch. In this embodiment, the push-button switch 4 is a conventional switch. Pressing the button part 41 once can switch the push-button switch 4 between on and off, and the lock body of the airtight door is electrically connected to the power supply through the push-button switch 4. Under normal circumstances, the push-button switch 4 is in the normally open state, the circuit is disconnected, the lock body of the airtight door has no power and is in the unlocked state. The output end of the air release switch module 3 will also be inserted into the air pipe 6 located outside the button housing 1, and there is no gas in the airtight door seal strip, so that the airtight door can be opened. When the place needs to be used for work, the airtight door needs to be closed. At this time, the push-button switch 4 needs to be energized to lock the airtight door, and the output end of the air release switch module 3 is moved away from the air pipe 6 located outside the button housing 1, and the airtight door seal strip is inflated to achieve sealing. When the integrated button 2 is pressed in an emergency, the push-button switch 4 can be disconnected, and the airtight door seal strip can be deflated to unlock the airtight door.
