Technical Field
[0001] This utility model belongs to the field of container technology, specifically, it relates to a sealing and insulated container. Background Technology
[0002] With the development of the refrigerated logistics industry and the prevailing trend of energy conservation and emission reduction, users have increasingly higher requirements for the energy efficiency of insulated containers. A large proportion of insulated containers are equipped with door curtains to reduce heat exchange between the inside and outside of the container when the doors are opened and closed, thereby reducing energy consumption. Currently, sliding door curtains are mostly installed in separate units, such as... Figure 1 , Figure 2 As shown, the sliding door curtain is installed at the highest level of the rear top panel of the container. This type of installation has the following problems: the distance between the door curtain and the door end is large, which will cause a significant loss of internal volume; the height of the door curtain is the same as the height of the container's internal top panel, resulting in higher costs.
[0003] Therefore, developing a sealing plate and insulated container that allows the door curtain connected to the sealing plate to be closer to the door end, further increasing the container's volume, reducing the height of the door curtain, and thus lowering the cost of the door curtain, is a technical problem that urgently needs to be solved. Utility Model Content
[0004] The purpose of this utility model is to provide a sealing plate and an insulated container, which allows the door curtain connected to the sealing plate to be closer to the door end, further increasing the volume of the container body and reducing the height of the door curtain, thereby reducing the cost of the door curtain.
[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In one aspect, this utility model proposes a sealing plate, comprising: A horizontal extension, the first end of which is used to connect to the inner roof of the container; A vertical extension, the first end of which is connected to the second end of the horizontal extension; A door curtain mounting groove is formed on the vertical extension, the lower part of the door curtain mounting groove has an open end, the upper end of the door curtain can be installed in the door curtain mounting groove, and the lower end of the door curtain extends from the open end to the lower part of the container door end. The plug-in portion has a first end connected to the second end of the vertical extension portion, and the second end of the plug-in portion is used to plug into the heat insulation component of the rear frame lintel.
[0006] In some embodiments of this application, a movable cavity is formed in the door curtain mounting groove, and the movable cavity is in communication with the opening end; The movable cavity is provided with a positioning protrusion, which is used to define the relative position of the upper end of the door curtain and the movable cavity.
[0007] In some embodiments of this application, a closed end is formed at the upper part of the door curtain mounting groove, and the closed end is disposed opposite to the open end; The positioning protrusion includes two positioning protrusion components, which are respectively formed on both sides of the opening end; The positioning protrusion assembly includes a first positioning protrusion and a second positioning protrusion. The first positioning protrusion is disposed at one end of the open end, and the second positioning protrusion is disposed on the closed end corresponding to the position of the first positioning protrusion.
[0008] In some embodiments of this application, a blocking portion is also included, which is connected to the lower end of the vertical extension and extends from the lower end of the vertical extension to below the opening end.
[0009] In some embodiments of this application, a first reinforcing part is further included, one end of which is connected to the vertical extension and the other end of which is connected to the door curtain mounting groove.
[0010] In some embodiments of this application, a second reinforcing portion is also included, one end of which is connected to the horizontal extension portion, and the other end of which is connected to the door curtain mounting groove.
[0011] In some embodiments of this application, the door curtain mounting groove is connected to the side of the vertical extension near the container body; Alternatively, the door curtain mounting groove is connected to the side of the vertical extension near the outside of the container.
[0012] In some embodiments of this application, the horizontal extension, the vertical extension, the curtain mounting groove, and the insertion part are integrally formed.
[0013] In some embodiments of this application, a positioning recess is formed on the first end of the horizontal extension, the first end of the horizontal extension is used to be connected to the inner top plate of the container by fasteners, and the positioning recess is used to mark the connection position of the first end of the horizontal extension and the inner top plate of the container by the fasteners.
[0014] On the other hand, this application also relates to an insulated container, including the sealing plate described in any of the above claims.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are: A horizontal extension is provided, connecting to the inner top panel of the container. A vertical extension is also provided, with a door curtain mounting groove on it. The door curtain mounting groove is used to install the door curtain. By connecting the door curtain mounting groove to the vertical extension, the height of the door curtain mounting groove is reduced, thereby reducing the height of the door curtain. Since the cost of the door curtain is calculated based on its area and its unit price is relatively high, reducing the height of the door curtain can reduce the cost of the door curtain. By installing the door curtain on the vertical extension, the distance between the door curtain and the door end can be shortened, thereby further increasing the effective volume inside the container.

[0024] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0025] In some embodiments of this application, a sealing plate is involved. Figures 3 to 12 As shown, it includes a horizontal extension 100, a vertical extension 200, a curtain mounting groove 300, and a plug-in part 400.
[0026] The horizontal extension 100, the vertical extension 200, the door curtain mounting groove 300, and the insertion part 400 all extend along the direction of the container door end 550 and are connected to the inner top plate 510 of the container through the horizontal extension 100.
[0027] The horizontal extension 100 extends horizontally. The vertical extension 200 extends vertically. A first end of the horizontal extension 100 is connected to the inner roof 510 of the container. A second end of the horizontal extension 100 is connected to the first end of the vertical extension 200. The second end of the vertical extension 200 extends to the vicinity of the container floor 520.
[0028] like Figures 3 to 12 As shown, a curtain mounting groove 300 is formed on the vertical extension 200. The curtain mounting groove 300 is used to mount the curtain 530.
[0029] To facilitate the installation of the curtain 530, an opening end 310 is formed at the lower part of the curtain mounting groove 300. The upper end of the curtain 530 is installed in the curtain mounting groove 300, and the lower end of the curtain 530 extends from the opening end 310 to the bottom of the curtain mounting groove 300, extending to the vicinity of the container floor 520.
[0030] In order to connect with the rear frame lintel 540 of the container, the sealing plate also includes a plug-in portion 400, the first end of which is connected to the vertical extension 200, and the second end of which is used to plug into the heat insulation component 541 of the rear frame lintel 540.
[0031] A movable cavity 320 is formed within the door curtain mounting groove 300. The movable cavity 320 communicates with the open end 310. The upper end of the door curtain 530 moves along the movable cavity 320. The lower end of the door curtain 530 extends from the open end 310 and hangs down to the vicinity of the container floor 520.
[0032] In this application, the specific shape and structure of the upper end of the curtain 530 are not limited, as long as the upper end of the curtain 530 can move along the moving cavity 320. The upper end of the curtain 530 can roll relative to the moving cavity 320 by means of rolling friction, or the upper end of the curtain 530 can slide relative to the moving cavity 320 by means of sliding friction.
[0033] Here, we will take the example of a curtain 530 with two coaxially connected rollers 531 at the upper end for explanation.
[0034] Two coaxially connected rollers 531 are embedded in the moving cavity 320 and can roll along the moving cavity 320.
[0035] To prevent the roller 531 from shaking inside the moving cavity 320, which could cause the roller 531 to move into the opening end 310 and become stuck, a positioning protrusion is provided inside the moving cavity 320.
[0036] The positioning protrusion is used to define the relative position of the upper end of the curtain 530 and the moving cavity 320.
[0037] With two rollers 531 coaxially connected to the upper end of the curtain 530, the positioning protrusion may include two positioning protrusion assemblies 330.
[0038] A closed end 340 is formed on the side of the door curtain mounting groove 300 opposite to the open end 310.
[0039] An opening 310 is formed in the middle of the lower part of the curtain mounting groove 300. Two positioning protrusions 330 are respectively disposed at both ends of the opening 310. Thus, two rolling areas are formed between the two positioning protrusions 330 and the two inner sidewalls of the moving cavity 320, and the two rollers 531 roll along the two rolling areas respectively.
[0040] Specifically, the positioning protrusion assembly 330 includes a first positioning protrusion 331 and a second positioning protrusion 332'.
[0041] A first positioning protrusion 331 is provided at one end of the opening end 310. Another first positioning protrusion 331 is provided at the other end of the opening end 310.
[0042] The second positioning protrusion 332 is disposed on the closed end 340 at a position corresponding to the first positioning protrusion 331. Another second positioning protrusion 332 is disposed on the closed end 340 at a position corresponding to another first positioning protrusion 331.
[0043] The first positioning protrusion 331, the second positioning protrusion 332 and the inner wall of the moving cavity 320 form a rolling area, which limits the roller 531 within the rolling area and prevents the roller 531 from rolling to the opening end 310 and getting stuck.
[0044] In some embodiments of this application, since air and heat leakage occurs at the connection point between the upper end of the curtain 530 and the moving cavity 320, a blocking part 600 is connected to the lower end of the vertical extension 200. The blocking part 600 extends from the lower end of the vertical extension to below the opening end 310, thereby blocking the upper end of the curtain 530. This avoids direct communication between the upper end of the curtain 530 and the door end 550, reducing heat loss at this location.
[0045] Since the curtain mounting groove 300 is formed on one side of the vertical extension 200, the side wall connecting the open end 310 and the closed end 340 of the curtain mounting groove 300 is connected to the vertical extension 200. The curtain mounting groove 300 is connected to the vertical extension 200 through this connection. Furthermore, a curtain 530 is movably connected to the curtain mounting groove 300. The weight of the curtain 530 is entirely applied to the curtain mounting groove 300. Therefore, in order to ensure the stability of the connection between the curtain mounting groove 300 and the vertical extension 200, a first reinforcing part 710 is also provided. One end of the first reinforcing part 710 is connected to the vertical extension 200, and the other end of the first reinforcing part 710 is connected to the curtain mounting groove 300 and the vertical extension 200.
[0046] In some other embodiments of this application, the sealing plate includes a second reinforcing portion 720, one end of which is connected to the horizontal extension portion 100, and the other end of which is connected to the door curtain mounting groove 300.
[0047] The door curtain mounting groove 300 is connected to the side of the vertical extension 200 near the container body.
[0048] In some other embodiments of this application, the door curtain mounting groove 300 is connected to the side of the vertical extension 200 near the outside of the container body.
[0049] The horizontal extension 100, the vertical extension 200, the curtain mounting groove 300, and the insertion part 400 can be integrally molded and obtained by extrusion.
[0050] The insertion part 400 and the blocking part 600 extend and are disposed at the same horizontal level, and the insertion part 400 and the blocking part 600 extend in opposite directions and are connected at the lower end of the vertical extension part 200.
[0051] The insertion part 400 can be a horizontally extending thin plate that can be directly inserted into the heat insulation component.
[0052] Since the curtain mounting groove 300 is connected to the lower end of the vertical extension 200, the height of the curtain 530 connected to the curtain mounting groove 300 can be reduced. Since the cost of the curtain 530 is calculated by area and the cost of the curtain 530 is relatively high, reducing the height of the curtain 530 can reduce the cost of the curtain 530. Furthermore, since the sealing part 600 is provided, the loss of cold air at the upper end of the curtain 530 can be avoided.
[0053] A positioning recess 110 is formed on the first end of the horizontal extension 100. The first end of the horizontal extension 100 is used to connect with the inner top plate of the container by fasteners. The positioning recess 110 is used to mark the connection position of the first end of the horizontal extension 100 and the inner top plate of the container by fasteners.
[0054] On the other hand, this application also relates to an insulated container with the aforementioned sealing plate installed on the rear frame lintel 540 at its door end 550.
[0055] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0056] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.
[0057] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
