The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

In a first aspect, as shown in fig. 1, 2 and 3, the present application provides an air duct port sealing device, including:

the sealing frame 100 is fixed on the air duct opening, and the inner side surface of the sealing frame 100 is provided with a lug 110;

the sealing cover 200 is provided with a first buckle 210 on the outer side, and the sealing cover 200 is detachably arranged on the sealing frame 100 through the buckling convex blocks 110 of the first buckle 210;

The heat insulator 300 is installed in the sealing cap 200.

Specifically, in the present application, the back surfaces of the sealing frame 100 and the sealing cover 200 are the surfaces of the sealing frame 100 and the sealing cover 200 facing the cabin inner cavity, and the front surfaces of the sealing frame 100 and the sealing cover 200 are the surfaces of the sealing frame 100 and the sealing cover 200 facing away from the cabin inner cavity.

More specifically, when the boot seal 200 needs to be pulled out, a pulling force is applied to the boot seal 200 such that the first buckle 210 presses the bump 110 to displace the bump 110, until the bump 110 leaves a space through which the first buckle 210 can pass, and then the first buckle 210 slides out from the edge of the bump 110, and the boot seal 200 is pulled out. Similarly, when the seal cover 200 needs to be pushed in, the seal cover 200 is pushed in the seal frame 100 after being aligned with the seal frame 100, and the pushing force applied to the seal cover 200 makes the protrusion 110 leave the space through which the first buckle 210 can pass, so that the first buckle 210 slides in from the edge, and the pushing process of the seal cover 200 is completed.

More specifically, the first snap 210 fastens the protrusion 110 when the sealing cap 200 is in the pushed-in state, enabling the sealing cap 200 to be firmly mounted on the air duct port when in the pushed-in state.

Preferably, the first fastener 210 and the protruding block 110 are provided in plurality, the plurality of first fasteners 210 are symmetrically disposed on two opposite outer sides of the sealing cover 200, the plurality of protruding blocks 110 are symmetrically disposed on two opposite inner sides of the sealing frame 100, so that the protruding blocks 110 and the first fasteners 210 can be stressed more uniformly when the sealing cover 200 is pulled out or pushed in, and the protruding blocks 110 and the first fasteners 210 are prevented from breaking.

More specifically, the heat insulator 300 is installed on the air passage port through the sealing cover 200, and since the temperature outside the shelter is higher than the temperature inside the shelter, the heat insulator 300 can prevent the heat outside the shelter from being transferred from the air passage port into the shelter, thereby enabling the inside of the shelter to be maintained at a low temperature.

In a more preferred embodiment, the inner side of the sealing frame 100 has a concave groove that mates with the first snap 210, and the bump 110 is located on the concave groove. The recessed groove ensures that the first snap 210 can be displaced in the direction of the sealing frame when the sealing cap 200 is pulled out or pushed in, and ensures that the bump 110 grips the first snap 210 when the sealing cap 200 is in the pushed-in state.

The sealing device for the air duct opening is provided with the sealing frame 100 with the first buckle 210 and the sealing cover 200 with the convex blocks 110, the convex blocks 110 are fastened by the first buckle 210, so that the sealing cover 200 can be firmly installed on the air duct opening when being in a pushing-in state, and the heat insulating piece 300 installed in the sealing cover 200 can prevent heat outside the shelter from being transferred into the shelter from the air duct opening, so that the inside of the shelter can keep low temperature.

In some preferred embodiments, the sealing frame 100 has a fold 120 on the back.

Specifically, when the sealing cap 200 is in a pushed-in state and contacts the back surface of the sealing frame 100, the bending portion 120 abuts against the back surface of the sealing cap 200, so that the push-in depth of the sealing cap 200 can be limited, and the sealing cap 200 is prevented from being pulled out difficultly and interfering with other structures inside the shelter due to the too deep push-in of the sealing cap 200. In this embodiment, the air duct port sealing device of the present application is provided with the bent portion 120 at the back of the sealing frame 100, and can limit the push-in depth of the sealing cap 200, thereby preventing the sealing cap 200 from being pulled out and the sealing cap 200 from interfering with other structures inside the shelter due to the too deep push-in of the sealing cap 200.

In some preferred embodiments, the seal housing 200 has a second snap 220 on the back thereof, and the insulation 300 is mounted to the seal housing 200 by the second snap 220.

In this embodiment, the air duct port sealing device of the present application is provided with the heat insulator 300 mounted on the sealing cover 200 through the second buckle 220, which enables the heat insulator 300 to be firmly mounted on the sealing cover 200, and has a simple structure, facilitating the mounting and dismounting of the heat insulator 300.

In some preferred embodiments, the front of the boot seal 200 has a recess 230 for pushing and pulling the boot seal 200.

Specifically, the groove 230 of the sealing cap 200 may be disposed on one side of the protruding portion or one side of the recessed portion of the sealing cap 200, in this embodiment, the front surface of the sealing cap 200 has a recessed portion recessed toward the air channel, and the groove 230 is disposed on the upper side of the recessed portion, so that the groove 230 faces downward, and dust accumulation of the groove 230 can be prevented.

In this embodiment, the air port sealing device of the present application is provided with the groove 230 for pushing and pulling the sealing cap 200, which enables the pushing and pulling process of the sealing cap 200 to be simplified.

As shown in fig. 4, in some preferred embodiments, a gap 310 is provided between the insulation 300 and the inner side of the seal housing 200;

the boot seal 200 has a notch 240 that communicates the front of the boot seal 200 with the gap 310.

Specifically, in order to prevent leakage of cold air, the conventional sealing cover 200 is closely attached to the duct port in the pushed-in state, and there is a negative pressure after the temperature in the shelter is lowered, so that the sealing cover 200 is difficult to be pulled out when the inside of the shelter is in a low temperature state. Therefore, in the present embodiment, the gap 240 and the gap 310 on the front side of the seal cover 200 are communicated to make the seal cover 200 not completely isolate the shelter, so that the negative pressure generated after the temperature in the shelter is reduced can be prevented, and the seal cover 200 can be pulled out smoothly when the temperature in the shelter is in a low-temperature state. The gap 240 and gap 310 form a channel small enough to transfer little heat from outside the shelter to the interior of the shelter without substantially affecting the maintenance of low temperatures in the shelter.

More specifically, the notch 240 may be located anywhere on the front of the boot seal 200 that is capable of communicating with the front of the boot seal 200 and the gap 310. Preferably, at least two notches 240 are provided and are symmetrically disposed at the junction between the front surface and the inner side surface of the seal cover 200, so as to prevent all notches 240 from being blocked when the heat insulator 300 is placed askew.

In this embodiment, the air duct port sealing device of the present application is provided with the gap 310 between the heat insulator 300 and the seal cover 200 and the notch 240 for communicating the front surface of the seal cover 200 with the gap 310, so that the seal cover 200 can be smoothly pulled out when the temperature in the shelter is low, because negative pressure is prevented from being generated after the temperature in the shelter is reduced.

In some preferred embodiments, the front face of the seal frame 100 has a spacer 130.

In this embodiment, the air duct port sealing device of the present application is provided with the cushion block 130 located on the front surface of the sealing frame 100, which can limit the pushing depth of the sealing cover 200 when pushing the sealing frame 100, and can prevent the sealing cover 200 from being pulled out difficultly and the sealing cover 200 from interfering with other structures inside the shelter due to the too deep pushing of the sealing cover 200. In some preferred embodiments, the front face of the boot seal 200 has a first flange 250.

Preferably, the sealing frame 100 has a second flange 140, and the first flange 250 is attached to the second flange 140 when the sealing cap 200 is in the pushed-in state.

In this embodiment, the air duct port sealing device of the present application is provided with the first flange 250 on the front surface of the sealing cap 200, so that the air duct port can be further sealed when the sealing cap 200 is in the pushed-in state; in addition, the air duct port sealing device of the present application is provided with the first flange 250 on the front surface of the sealing cover 200, so that the pushing depth of the sealing cover 200 when pushing into the sealing frame 100 can be limited, and the sealing cover 200 is prevented from being pulled out difficultly and interfering with other structures in the shelter due to the fact that the sealing cover 200 is pushed too deeply.

In some preferred embodiments, the air port sealing device further includes a magnet 400 mounted on the sealing cap 200.

Specifically, in order to prevent the pulled out boot seal 200 from being left free to cause its loss, it is necessary to properly place the pulled out boot seal 200.

More specifically, the shelter with the air duct opening is made of ferromagnetic metal. After the seal cover 200 is pulled out from the seal frame 100, the side with the magnet 400 is close to the shelter, so that the seal cover 200 is adsorbed on the shelter based on magnetism, and the seal cover 200 is prevented from being lost due to random placement.

The installation mode of the magnet 400 can be any installation mode capable of fixing the magnet 400 on the sealing cover 200, in this embodiment, the magnet 400 is buckled on the sealing cover 200, so that the magnet 400 can be firmly installed on the sealing cover 200, and the structure is simple, and the installation and the disassembly of the magnet 400 are convenient.

In this embodiment, the air duct port sealing device of the present application is provided with the magnet 400 mounted on the sealing cap 200, so that the pulled sealing cap 200 can be adsorbed on the shelter, and the sealing cap 200 can be prevented from being lost due to random placement.

The sealing frame 100 is fixedly installed on the air duct opening, and the implementation manner thereof may be an existing installation manner, and in this embodiment, the sealing frame 100 is connected with the air duct opening by screws.

Specifically, the air duct port is used for connecting the shelter and the refrigerating unit when the shelter is required to be filled with cold. When the cabin is not required to be filled with cold, the sealing cover 200 is pushed into the sealing frame 100 to seal the air duct opening, and when the cabin is required to be filled with cold, the sealing cover 200 is pulled out of the sealing frame 100, and the cabin is connected with the refrigerating unit through the air duct opening to be filled with cold.

According to the shelter provided by the application, the sealing frame 100 with the first buckle 210 and the sealing cover 200 with the convex blocks 110 are arranged, the convex blocks 110 are fastened by the first buckle 210, so that the sealing cover 200 can be firmly installed on the air duct opening when being in a pushing-in state, and the heat insulation piece 300 installed in the sealing cover 200 is arranged, so that heat outside the shelter can be prevented from being transferred into the shelter from the air duct opening, and the temperature in the shelter can be kept low.
