Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

It should be noted that, in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention, but not for requirements that the present invention must be constructed and operated in a specific direction, and therefore, the present invention should not be construed as being limited thereto. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1

As shown in fig. 1 to 2, an operating room pressure relief device comprises a pressure relief device, wherein the outer end of the pressure relief device is connected with a metal plate of a vehicle body, the pressure relief device 2 comprises a pressure relief port bracket 20 and a vent plate 22 which are arranged from inside to outside, and a plurality of pressure relief ports 201 penetrating through the pressure relief port bracket 20 are arranged on the pressure relief port bracket 20; each pressure relief opening 201 is rotatably connected with an intermediate rubber plate 21 for opening and closing the pressure relief opening 201, and the intermediate rubber plate 21 is positioned at one side close to the ventilation plate 22; the ventilation plate 22 is provided with a plurality of ventilation holes corresponding to the pressure relief openings 201.

This application is through middle offset plate, pressure release mouth support to and have the ventilating board in ventilation hole, can make gaseous automatic outflow outdoor because indoor outdoor pressure differential, reach the purpose of pressure release, prevent the damage that pressure caused the eardrum in the twinkling of an eye, it is specific, when indoor pressure is big, gaseous through the middle offset plate of pressure release mouth impact make middle offset plate rotate and open the pressure release mouth, and then make indoor pressure follow the ventilation hole outflow on the ventilating board.

Meanwhile, outdoor air flow cannot enter the room due to the blocking of the middle rubber plate, indoor air is prevented from being polluted by outdoor air, and the operation comfort level of operators is improved.

Further, pressure relief device 2 can the joint on automobile body panel beating 1, or pressure relief device 2 is connected with automobile body panel beating 1 through the bolt to guarantee that connection between them is stable.

Referring to fig. 2, the middle rubber plate 21 is hinged or connected with the pressure relief port bracket 20 by a limit buckle, preferably. And a gap barrier 202 used for limiting the middle rubber plate 21 is further arranged on the pressure relief opening 201, and the gap barrier 202 is positioned on one side far away from the ventilating plate 22.

In some further embodiments, the gap stop 202 is in the form of two vertically disposed bars, which do not impede the flow of the internal airflow outward.

When indoor atmospheric pressure is greater than outdoor atmospheric pressure, the air flows out from pressure release port 201 because the atmospheric pressure difference is automatic, so air current jack-up middle offset plate 21, middle offset plate 21 is the first direction around hinge pivoted direction this moment, the direction of rotation opposite with the first direction is the second direction, flow outdoor after air current jack-up middle offset plate 21, thereby reduce indoor atmospheric pressure, because set up a plurality of pressure release ports 201 on the pressure release port support 20, the clearance of every pressure release port 201 blocks 202 separation middle offset plate 21, make middle offset plate 21 can't rotate around the hinge with the second direction, so, after indoor pressure release, the air of outdoor inflow is blocked by middle offset plate 21, avoid outdoor air pollution to indoor.

Through this design, can avoid indoor air to suffer outdoor air's pollution, improve operating personnel operating comfort.

It should be noted that, as shown in fig. 2, each small rubber plate area in the middle rubber plate 21 covers a pressure relief port 201 and a vent hole, which are arranged to reduce the mass of each rubber plate, and when the difference between the indoor air pressure and the outdoor air pressure is small, the indoor air is enough to jack up the rubber plate.

In some further embodiments, the middle rubber plate 21 is made of rubber or silicone material, and the thickness of the middle rubber plate is 2mm. The number of the pressure relief ports 20 and the middle rubber plates 21 can be designed as required, and can be 6.

The working principle is as follows: when operating personnel is closing the indoor air pressure in the twinkling of an eye that the control chamber door in-process produced and being greater than outdoor air pressure, cause indoor to outdoor pressure differential this moment, at this moment, indoor air flows to outdoor through pressure release port 20, in-process at the play, air current jack-up middle offset plate 21, because the top of middle offset plate 21 is connected with the top of pressure release port support 20, make middle offset plate 21 bottom lift with the first direction rotation, the air current flows to outdoor from the clearance department that middle offset plate 21 bottom lifted, accomplish the process of indoor pressure release, after the pressure release, when wind blows to indoor, because, clearance barrier 202 between every pressure release port 201, these clearance barriers 202 the middle offset plate 21 bottom and moves toward the second direction, middle offset plate 21 plays the effect that the outside air current of separation got into indoor this moment, outside dust pollution indoor environment has been avoided.
