Description

TECHNICAL FIELD

[0001] The utility model relates to building door and window technical field, specifically for a kind of pressure relief window for dustless workshop. BACKGROUND

[0002] Dustless workshop refers to the closed space that through air filtration, pressure control, temperature and humidity regulation and other means, the pollutants such as particulate, harmful gas, bacteria in air are controlled in specific range, and pressure relief window is the key equipment in dustless workshop pressure control system, when the pressure difference between inside and outside workshop is too large, it is automatically or manually opened, releases excess pressure, protects workshop structure and equipment safety, and in emergency such as fire, explosion, rapidly relieves pressure, reduces accident risk.

[0003] However, in actual use process, we find that pressure relief window directly contacts between window body and frame when opening and closing, which not only generates huge noise, affects the comfort of working environment, but also causes window body deformation, sealing strip wear and other problems due to long-term collision, thereby shortens the service life of pressure relief window, in addition, part of manually closed pressure relief window lacks hand anti-pinch device, and staff is easily pinched finger due to window body sudden closing when operating, and there is great safety hazard, these problems reduce the reliability of equipment, and therefore, we propose a kind of pressure relief window for dustless workshop.

[0008] A buffer assembly arranged between the frame body and the upper pressure relief window, for avoiding rapid impact on the frame body when closing and opening the upper pressure relief window to the maximum angle.

[0009] In some embodiments, the buffer assembly comprises an arc-shaped plate arranged on the side surface of the upper pressure relief window, the top end of the arc-shaped plate is provided with a piston plate, the side edge of the frame body is provided with an arc-shaped shell, and the piston plate is movably arranged on the inner wall of the arc-shaped shell.

[0010] In some embodiments, the arc-shaped shell is provided with a rubber cylinder I on the inner side of the frame body, and the arc-shaped shell is provided with a rubber cylinder II on the inner side of the arc-shaped plate, and the rubber cylinder I and the rubber cylinder II are connected with the inside of the arc-shaped shell, and the two sides of the arc-shaped shell are provided with through grooves which are connected with each other, and the upper pressure relief window is provided with an anti-pinch part for limiting when the lower pressure relief window is closed.

[0011] In some embodiments, the anti-pinch part comprises a conical bottom rod movably arranged in the inside of the upper pressure relief window, and the top of the lower pressure relief window is provided with a circular groove, and the bottom end of the conical bottom rod is movably arranged in the inside of the circular groove.

[0012] In some embodiments, the side of the frame body is provided with an arc-shaped side block, the top end of the conical bottom rod is movably arranged on the outer surface of the arc-shaped side block, and the outer surface of the conical bottom rod is sleeved with a spring, and one end of the spring is arranged on the top of the upper pressure relief window.

[0013] In some embodiments, the bottom of the upper pressure relief window is provided with a groove, the inner wall of the groove is provided with a fixed rod on both sides, the top of the lower pressure relief window is provided with a rotating block, and the inside of the rotating block is movably arranged on the outer surface of the fixed rod.

[0015] The utility model at least has the following beneficial effects:

[0016] 1. By dividing the window body into an upper pressure relief window and a lower pressure relief window, and cooperating with the anti-pinch part, when the window body is not completely closed, the upper and lower pressure relief windows are kept relatively independent movement through the movable connection structure, which not only effectively avoids the risk of injuring the staff during the window body closing process, but also significantly improves the safety of operation.

[0017] 2. By arranging the buffer assembly, when the upper pressure relief window is quickly opened, the window body can smoothly move in the initial stage and is almost not affected by resistance, and when the window body approaches the frame body, the buffer assembly starts to play a role, so that the window body slowly rotates, avoiding violent collision with the frame body. Similarly, in the closing process, the window body will also enter the buffer state before approaching complete closure, slowly moving to ensure smooth closing, which not only effectively reduces the impact force and noise between the window body and the frame body, but also significantly prolongs the service life of the pressure relief window.

[0033] The arc-shaped shell 41 is provided with a rubber cylinder I 43 on the inner side of the frame 1, and the arc-shaped shell 41 is provided with a rubber cylinder II 44 on the inner side of the arc-shaped plate 42, and the rubber cylinder I 43 and the rubber cylinder II 44 are both connected with the inside of the arc-shaped shell 41, and the arc-shaped shell 41 is provided with a through groove 45 on both sides, which are connected with each other, and the upper pressure relief window 2 is provided with an anti-pinch part 5 for limiting when the lower pressure relief window 3 is closed, and when opening and closing, the piston plate 46 can push the gas in the arc-shaped shell 41 out through the rubber cylinder I 43, and when closing, the gas is pushed out through the rubber cylinder II 44, and since the rubber cylinder I 43 and the rubber cylinder II are both open at both ends, the gas is not as much as in the arc-shaped shell 41, thus producing a buffering effect.

[0034] The anti-pinch part 5 comprises a conical bottom rod 52 movably arranged in the inside of the upper pressure relief window 2, the top of the lower pressure relief window 3 is provided with a circular groove 51, the bottom end of the conical bottom rod 52 is movably arranged in the inside of the circular groove 51, and the bottom end of the conical bottom rod 52 is provided with a cone, so as to facilitate the insertion into the inner wall of the circular groove 51.
