Description

Technical Field

[0001] The utility model belongs to the technical field of external circulation laminar flow transfer equipment, in particular to an external circulation laminar flow transfer window. Background Art

[0002] Laminar flow transfer windows are mainly used in biological clean areas for the transfer of items. The main application places are: biopharmaceuticals, scientific research institutions, disease control centers, large hospitals, university research, biological cleanliness and various clean areas of application.

[0003] Since conventional laminar flow transfer windows lack a standardized operating correction structure, it is easy to cause the windows and doors on both sides to be opened at the same time, causing the air flow speed exchange on both sides to accelerate, thus causing the conventional laminar flow transfer windows to have a relatively low practicality.

[0004] To this end, we proposed an external circulation laminar flow transfer window to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of low practicability of conventional laminar flow transfer windows and proposes an external circulation laminar flow transfer window.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An external circulation laminar flow transfer window comprises a window frame, a baffle is fixedly connected to the side end of the window frame, a correction bolt is slidably installed between the baffle and the window frame, a window door is symmetrically slidably installed at the window of the window frame, a limit plate is fixedly connected to the lower outer end of the window frame, and the limit plate is in active contact with the window door. When the window door on one side of the window frame is pulled outward, when the correction bolt just deviates to the window door on this side, the window door is used to push the correction bolt to the window door on the other side, so that the other side of the correction bolt is blocked outside the window door, hindering the window door on the other side from opening, preventing the windows and doors on both sides from being opened at the same time, and realizing error avoidance through a simple structure, thereby improving practicality.

[0008] Preferably, the window frame comprises a frame body and a limit frame. The limit frame is used to limit the sliding range of the correction bolt, so as to prevent the correction bolt from sliding out and falling.

[0009] Preferably, the window frame further comprises a guide wheel, which is rotatably mounted on the lower part of the frame body. The guide wheel is used to roll on the window door, thereby reducing the sliding resistance of the window door and improving the smoothness of pulling the window door.

[0010] Preferably, the window frame further comprises a leather frame, which is symmetrically fixedly connected to the interior of the frame. The leather frame is used to block between the frame and the window door, thereby increasing the sealing between the window frame and the window door and reducing the interference of airflow on both sides.

[0011] Preferably, the window door comprises a glass frame and a handle, and the handle is fixedly connected to the outer end of the glass frame. The handle is held to pull the glass frame to slide, so that the window door on one side is opened, and the glass frame is blocked outside the correction bolt, so that the correction bolt blocks the window door on the other side, thereby preventing the windows and doors on both sides from being opened at the same time.

[0012] Preferably, the window door further comprises a roller, and the roller is rotatably mounted on the lower part of the glass frame, so as to reduce the sliding resistance between the glass frame and the frame body.

[0013] Preferably, the correction bolt comprises a push block and a slide rod, wherein the push block is symmetrically fixedly connected to the side end of the slide rod. When the glass frame acts on the push block, the push block pushes the slide rod, causing the slide rod to slide along the other side, so that the push block on the other side blocks the window door on the other side, facilitating automatic error correction.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. When the window door on one side of the window frame is pulled outward, when the correction bolt is just biased toward the window door on that side, the window door is used to push the correction bolt to the window door on the other side, so that the other side of the correction bolt is blocked outside the window door, hindering the opening of the window door on the other side, preventing the windows and doors on both sides from being opened at the same time, and achieving error avoidance through a simple structure, thereby improving practicality.

[0016] 2. Use the guide wheel to roll on the windows and doors to reduce the sliding resistance of the windows and doors and improve the smoothness of pulling the windows and doors.

[0017] 3. Use a leather frame to block between the frame and the window door to increase the sealing between the window frame and the window door and reduce the interference of airflow on both sides.

[0018] 4. Hold the handle and pull the glass frame to slide to open the window on one side. Use the glass frame to block the correction bolt so that the correction bolt blocks the window on the other side, thus preventing the windows on both sides from opening at the same time.

[0019] 6. When the glass frame acts on the push block, the push block pushes the slide bar, causing the slide bar to slide along the other side, so that the push block on the other side blocks the window door on the other side, facilitating automatic error correction.
