Description

Technical Field

[0001] The utility model relates to the technical field of clean room transfer windows, in particular to a mechanical interlock transfer window for clean rooms. Background Technique

[0002] The mechanical interlock transfer window for clean rooms is a highly efficient and reliable item transfer device designed specifically for clean environments. It adopts a mechanical interlock mechanism to ensure that the two side doors of the transfer window cannot be opened simultaneously during the item transfer process. The transfer window usually consists of two side door bodies, an intermediate working area, and a mechanical interlock device. The mechanical interlock mechanism is the core part of the transfer window, which realizes the interlock function of the two side doors through a mechanical structure. When one side door is in the open state, the other side door will be locked and cannot be opened; only when this side door is completely closed can the other side door be unlocked and opened.

[0003] For example, the Chinese patent "A Transfer Window for Clean Rooms" with the publication number CN215108364U includes a table body, a window body is fixedly connected to the top of the table body, a placement opening is formed on one side of the window body, a transfer door is movably connected to one side of the window body, a fixing plate is fixedly connected to one side of the window body, a door handle is fixedly connected to one side of the transfer door, and a mounting plate is movably connected to the inner top wall of the window body; an ultraviolet sterilization lamp is fixedly connected to the bottom of the mounting plate, a mounting hole is formed in the bottom of the mounting plate, a bolt is movably connected to the inner wall of the mounting hole, a washer is movably connected to the outer wall of the bolt, a clamping groove is formed in the inner side wall of the window body, a clamping block is movably connected to the inner wall of the clamping groove, and a placement plate is fixedly connected to one side of the clamping block.

[0004] Although the above-mentioned prior art can realize the opening and closing of the transfer window, in actual use, on the one hand, it is difficult to lock the two end window doors to each other. If there is accidental touch during sample transfer, both end window doors may be opened, allowing the air in the environment to enter the interior of the window body, thereby contaminating the sample. On the other hand, it is difficult to clean the dust attached to the sample. After the sample is placed in the window body and disinfection operations are carried out, the dust attached to the sample is difficult to clean, thus affecting the sample test results. Therefore, it does not meet the existing requirements, and for this reason, we propose a mechanical interlock transfer window for clean rooms. Content of the Utility Model

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. With the first rotating hook and the second rotating hook, the window doors at both ends can be locked to each other. When the first window door needs to be opened, first pull the second pull rod, which drives the first rotating hook to rotate clockwise, and at the same time the first return spring is further compressed until the first rotating hook separates from the first upper clamping plate. At this time, pull the handle on the first window door to open the first window door, and at the same time the first return spring is reset. The reset of the first return spring pushes the first rotating hook to rotate counterclockwise until the rear end of the first rotating hook is clamped and fixed to the second upper clamping plate, thereby locking the second window door. When the second window door needs to be opened, first pull the first pull rod, which drives the second rotating hook to rotate counterclockwise, and at the same time the second return spring is further compressed until the second rotating hook separates from the second lower clamping plate. At this time, pull the handle on the second window door to open the second window door, and at the same time the second return spring is reset. The reset of the second return spring pushes the second rotating hook to rotate clockwise until the front end of the second rotating hook is clamped and fixed to the first lower clamping plate, thereby locking the first window door, avoiding the simultaneous opening of the window doors at both ends due to accidental touch, and thus reducing the pollution of the sample by the external environment.

[0015] 2. With the spray head and the air filter box, the dust on the sample can be cleaned. After the sample is placed in the window body and the first window door and the second window door are both closed and sealed, at this time, air is blown into the air inlet pipe by an external blower. The air flows into the air distribution box after being filtered by the air filter box. Multiple pipes inside the air distribution box are all connected to the spray head. At this time, the air flow sprays out from the spray head from the air distribution box, and the sprayed air flow cleans the dust on the sample. At the same time, the air flow is discharged from the window body through the air outlet pipe, making the air circulate, avoiding the interference caused by dust during sample detection, and thus improving the accuracy of the sample detection result.

[0016] 3. The utility model can disinfect samples evenly through a fixing frame and ultraviolet lamps. After the samples are placed inside the form and the dust on the samples has been removed, the ultraviolet lamps are powered on. At this time, multiple ultraviolet lamps on both sides disinfect and sterilize the samples, and the samples stay inside the form for more than 30 minutes. After the disinfection and sterilization are completed, the second window door is opened, and the samples are taken out of the form for subsequent operations. The multiple ultraviolet lamps make the ultraviolet irradiation more uniform, thus improving the disinfection and sterilization effect. BRIEF DESCRIPTION OF THE DRAWINGS
