Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cold storage door technology, and in particular to a fiberglass cold storage door. Background Technology
[0002] Cold storage doors are special industrial doors installed in cold storage equipment and frozen warehouses for insulation and sealing. During use, cold storage doors are often equipped with viewing glass to facilitate observation of the inside of the cold storage from the outside. However, the viewing glass is located on one side of the cold storage and is prone to icing, which reduces the visibility of the viewing glass and reduces the ease of use of the cold storage door.
[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN222849569U) for a high-insulation cold storage viewing door. The door includes a door body with an installation groove at its front end. Window bases are inserted into the four inner walls of the installation groove. Pressure strips are snapped onto both ends of the window bases. An observation component is fixedly connected between two pressure strips. The observation component includes three single-layer tempered glass panes. Two installation strips are fixedly connected between two adjacent single-layer tempered glass panes, forming a vacuum cavity between them. A fixed frame is fixedly connected to the lower end of the middle single-layer tempered glass pane. A liquid crystal touch screen is fixedly embedded in the front end of the fixed frame. Using this observation component and other structures, frequent opening of the door to enter the cold storage is unnecessary, effectively preventing cold air leakage and condensation. However, this cold storage door does not consider the phenomenon that the viewing glass located on one side of the cold storage is prone to icing, reducing the visibility of the viewing glass and decreasing the ease of use of the cold storage door. Utility Model Content
[0004] The purpose of this utility model is to provide a fiberglass cold storage door to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass cold storage door, comprising:
[0006] The cold storage door is made of fiberglass. A sealing frame is connected to the side of the cold storage door. A fixed through groove is opened on the side of the cold storage door near the sealing frame. The inner cavity of the fixed through groove is equipped with two horizontally symmetrically arranged viewing glass.
[0007] The cleaning assembly is installed in the fixed through groove of the cold storage door and is used to clean the viewing glass. The cleaning assembly includes a fixed plate and two connecting plates. The opposite sides of the two connecting plates are welded to the cold storage door. The curved surface of the fixed plate is connected to the two connecting plates. The side of the fixed plate is rotatably connected to a rotating rod through a bearing. The two ends of the rotating rod are respectively connected to a rotating disk and a cleaning plate for cleaning the viewing glass.
[0008] Preferably, the side of the cleaning plate closest to the rotating rod makes sliding friction contact with the viewing glass, and the side of the cleaning plate makes sliding friction contact with the fixing plate.
[0009] Preferably, the curved surfaces of both viewing glass panes are connected to the cold storage door body, and the adjacent sides of the two viewing glass panes are respectively connected to a fixed plate and two connecting plates.
[0010] Preferably, the upper part of the cold storage door is connected to a positioning slide plate, and a positioning slide rail is embedded in the side of the positioning slide plate.
[0011] Preferably, the lower part of the cold storage door is provided with a support component, which includes a support slide plate and a support rail.
[0012] Preferably, the top surface of the support slide plate is connected to the cold storage door, and two symmetrically arranged wedge plates are slidably connected to both sides of the support slide plate.
[0013] Preferably, the support slide rail is located on the adjacent side of the two wedge plates, and the bottom surface of the support slide plate is slidably connected to the support slide rail.
[0014] Preferably, the vertical height of the support slide rail is the same as the vertical height of the two wedge plates.
[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0016] This fiberglass cold storage door features two viewing windows, allowing users to observe the interior of the cold storage from the outside. However, during use, ice easily forms on the side of the viewing windows located within the cold storage, reducing visibility. Thanks to the design of the cleaning assembly, ice crystals condensing on the surface of the viewing windows can be removed, improving visibility and thus enhancing the ease of use of the cold storage door. With the connection of the rotating rod, rotating the rotating disc rotates the cleaning plate, allowing it to scrape away the ice crystals on the surface of the viewing windows, further improving visibility. The fixing plate and two connecting plates secure the rotating position of the rotating rod, strengthening the structural stability of the cold storage door's components.
[0017] This fiberglass cold storage door, thanks to its support component design, provides support for the door body. The support rails and two wedge plates are all installed on the ground, increasing the length of the support slide plate connected to the door body and sliding along the rails, thus enhancing the door's stability. Since the support rails and wedge plates are all ground-mounted, they do not obstruct normal entry and exit, while also strengthening the door's stability. Furthermore, the vertical extension height of the support rails is the same as that of the two wedge plates, allowing rollers to smoothly pass through the door, further improving the door's ease of use.
[0018] This fiberglass cold storage door, thanks to its positioning rails and sliding plate design, provides further stability for the movement of the door. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0031] Please see Figures 1 to 4 A fiberglass cold storage door, in this embodiment including:
[0032] The cold storage door 1 is made of fiberglass. The cold storage door 1 includes a door frame, door edge, and door panel, all of which are made of fiberglass. The cold storage door 1 is not the subject of this utility model and will not be described in detail. A sealing frame 2 is connected to the side of the cold storage door 1. A fixing groove is opened on the side of the cold storage door 1 near the sealing frame 2. The inner cavity of the fixing groove is provided with two horizontally symmetrically arranged viewing glass 3. The two viewing glass 3 are the same size.
[0033] The cleaning component 4 is installed in the fixed through groove of the cold storage door 1 and is used to clean the visible glass 3. The cleaning component 4 includes a fixed plate 41 and two connecting plates 44. The opposite sides of the two connecting plates 44 are welded to the cold storage door 1. The curved surface of the fixed plate 41 is connected to the two connecting plates 44. The two connecting plates 44 are arranged vertically symmetrically with the fixed plate 41 as the axis. The side of the fixed plate 41 is rotatably connected to a rotating rod 42 through a bearing, so that the fixed plate 41 fixes the rotation position of the rotating rod 42.
[0034] The rotating rod 42 has a rotating disk 45 and a cleaning plate 43 for cleaning the viewing glass 3 connected to its two ends respectively. Since the viewing glass 3 is prone to icing on the side near the cold storage, the cleaning plate 43 is located on the side of the viewing glass 3 near the cold storage. This allows the cleaning plate 43 to scrape the surface of the viewing glass 3, thereby scraping away the ice crystals that have condensed on the surface of the viewing glass 3, improving the visibility of the viewing glass 3, and thus improving the ease of use of the cold storage door. The two connecting plates 44 are used to fix the position of the fixing plate 41. When the cold storage door is closed, since the cleaning plate 43 is located inside the cold storage, the rotating disk 45 is located outside the cold storage. The rotating disk 45 can be rotated from the outside. During the transmission process, the cleaning plate 43 rotates around the rotating rod 42 as the axis, thereby cleaning the ice crystals that have condensed on the surface of the viewing glass 3.
[0035] The cleaning plate 43 has sliding friction contact with the viewing glass 3 on the side near the rotating rod 42, and the side of the cleaning plate 43 has sliding friction contact with the fixing plate 41. When the cold storage door is closed, the side of the fixing plate 41 near the cold storage and the side of the two connecting plates 44 near the cold storage are flush with the side of the two viewing glasses 3 near the cold storage, providing conditions for the cleaning plate 43 to fully scrape and clean the surface of the viewing glass 3. The curved surfaces of the two viewing glasses 3 are connected to the cold storage door body 1, and the adjacent sides of the two viewing glasses 3 are connected to the fixing plate 41 and the two connecting plates 44 respectively. The upper part of the cold storage door body 1 is connected to the positioning slide plate 5, and the side of the positioning slide plate 5 is slidably connected to the positioning slide rail 6, so that the positioning slide plate 5 moves along the path of the positioning slide rail 6, thereby fixing the movement path of the cold storage door body 1.
[0036] A support component 7 is provided at the lower part of the cold storage door 1. Thanks to the design of the support component 7, the movement of the cold storage door 1 can be further fixed. The existing cold storage door slide rail and slide plate are usually designed in the middle of the cold storage door 1, which often results in a small slide plate area and reduces the movement stability of the cold storage door 1. The support component 7 includes a support slide plate 71 and a support slide rail 72. The top surface of the support slide plate 71 is connected to the cold storage door 1. Two symmetrically arranged wedge plates 73 are slidably connected to both sides of the support slide plate 71. The support slide plate 71 and the two wedge plates 73 are installed on the ground, so that the support slide rail 72 can pass through the cold storage entrance, thereby increasing the contact area between the support slide plate 71 and the support slide rail 72 and enhancing the movement stability of the cold storage door. The support slide rail 72 is set on the adjacent side of the two wedge plates 73. The bottom surface of the support slide plate 71 is slidably connected to the support slide rail 72. The vertical height of the support slide rail 72 is the same as the vertical height of the two wedge plates 73.
[0037] To perform cleaning, the rotating disk 45 is manually rotated. With the connection of the rotating rod 42, the cleaning plate 43 rotates around the rotating rod 42 as the axis, scraping away the ice crystals condensed on the surface of the viewing glass 3 and improving the visibility of the viewing glass 3. Thanks to the design of the fixed plate 41 and the two connecting plates 44, the rotation of the rotating rod 42 can be supported, and the structural stability of the cold storage door components can be strengthened.
[0038] For support, the support slide rail 72 and the two wedge plates 73 are installed on the ground, allowing the support slide rail 72 to pass through the entrance of the cold storage. This allows the support slide plate 71, which moves along the path of the support slide rail 72, to be directly connected to the cold storage door 1. The support slide plate 71 can be adjusted according to actual usage requirements, thereby enhancing the movement stability of the cold storage door 1.
[0039] Regarding the specific locking and fixing issue after the cold storage door 1 is moved, the locking and fixing structure is not part of the content to be protected by this utility model and will not be described in detail.
[0040] Working principle
[0041] When in use, the rotating disk 45 rotates and the cleaning plate 43 rotates around the rotating rod 42 as the axis to scrape and clean the ice crystals condensed on the surface of the visible glass 3, thereby improving the visibility of the visible glass 3. The fixing plate 41 and the two connecting plates 44 are used to support and fix the rotation position of the rotating rod 42.
[0042] This causes the positioning slide plate 5 to move along the path of the positioning slide rail 6, and the support slide plate 71 to move along the path of the support slide rail 72. At the same time, the support slide plate 71 slides on the adjacent sides of the two wedge plates 73, so that the cold storage door 1 can be moved stably.
