Description

Technical Field

[0001] The utility model belongs to the technical field of transfer windows, and in particular relates to a transfer window which is convenient to open and close. Background Art

[0002] The transfer window is an auxiliary equipment of the clean room, which is mainly used for the transfer of small items between clean areas and between clean areas and non-clean areas, so as to reduce the number of times the clean room door is opened and minimize the pollution to the clean room.

[0003] Since the door of a conventional transfer window opens in a fan shape, it is very inconvenient to pull it because it does not conform to the natural movement posture of the hand. Moreover, when stuffing things in after opening it, the hand needs to be stretched as far as possible, so the head needs to avoid the top, which makes the operation of a conventional transfer window relatively difficult.

[0004] Therefore, we propose a transfer window that is easy to open and close to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that the conventional transfer window is difficult to operate, and proposes a transfer window which is easy to open and close.

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

[0007] A delivery window that is easy to open and close includes a top cover and a window frame, wherein the top cover is fixedly connected to the upper end of the window frame, a lifting door is slidably installed inside the window frame, a drawer is slidably installed at the lower part of the window frame, and the lower end of the lifting door is in rolling contact with the drawer. The drawer is pulled outward, so that the drawer acts upward on the lifting door, so that the lifting door rises and opens along the window frame, and then the product is placed on the drawer and pushed into the window frame, and the staff on the other side pulls out the product, avoiding a large arc window opening, making the window opening action smoother, and reducing the difficulty of reaching out to pick up the goods by extending the drawer, thereby improving the convenience of product delivery.

[0008] Preferably, the upper part of the window frame is rotatably connected with a guide wheel, and the guide wheel is in rolling contact with the lifting door. The guide wheel is used to reduce the resistance of the lifting door to the lifting movement.

[0009] Preferably, the window frame comprises a frame body, a fixed shaft and a limit block, wherein the fixed shaft is fixedly connected to the upper part of the frame body. The limit block is used to limit the drawer withdrawal range, thereby conveniently preventing the drawer from being completely withdrawn.

[0010] Preferably, the lifting door comprises a door frame, a first sealing strip, a transparent plate and a second sealing strip, wherein the first sealing strip is symmetrically fixedly connected to the side ends of the door frame, the transparent plate is fixedly connected to the lower part of the door frame, and the second sealing strip is fixedly connected to the lower end of the door frame. When the door frame is subjected to an upward force, the door frame is lifted upward along the guide wheel, so that the drawer is unfolded.

[0011] Preferably, the lifting door further comprises a roller, which is rotatably connected to the lower part of the door frame, and the roller is used to reduce the friction between the door frame and the drawer.

[0012] Preferably, the drawer includes a push-up frame, a sliding plate and a handle, and a groove is provided on the upper portion of the push-up frame. The handle is held and the sliding plate is pulled, and the sliding plate acts on the push-up frame, so that the push-up frame drives the lifting door to unfold. When the drawer is pulled out, the groove is used to stabilize the roller, so that the drawer can be kept in an unfolded state.

[0013] Preferably, the drawer further comprises a stop bar, and a height limiting bar is provided on the upper part of the push-lift frame. The height limiting bar is used for elevation, and the stop bar is used for positioning the product, so as to facilitate standardized operation.

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

[0015] 1. Pull the drawer outward so that the drawer acts on the lifting door upward, causing the lifting door to rise and open along the window frame. Then place the product on the drawer and push it into the window frame. The staff on the other side pulls out the product to avoid large-scale arc window opening, making the window opening action smoother. By extending the drawer, the difficulty of reaching out to pick up the goods is reduced, thereby improving the convenience of product delivery.

[0016] 2. The drawer includes a push-up frame, a sliding plate and a handle. A groove is provided on the upper part of the push-up frame. The sliding plate is pulled by holding the handle, and the sliding plate acts on the push-up frame, so that the push-up frame drives the lifting door to unfold. When the drawer is pulled out, the groove is used to stabilize the roller, so that the drawer can be kept in an unfolded state. BRIEF DESCRIPTION OF THE DRAWINGS
