Description

Technical Field

[0001] The utility model relates to the technical field of sealed doors, in particular to a double-sealed structure door. Background Art

[0002] Due to the low temperature in northern my country in winter, building insulation is particularly important. In building insulation projects, in addition to building wall insulation projects, building door and window insulation is also a factor that must be considered. Since the building door body needs to be frequently opened and closed in a low temperature environment, the insulation effect of the building door body must be ensured. Existing insulation doors usually use sealing strips to seal between the door body and the door frame to achieve the insulation effect. However, the current door body and the door frame are only sealed by one sealing strip, and the sealing conditions are single. In addition, since the door body needs to be frequently opened and closed, the sealing strip is prone to deformation or aging after a period of use, affecting the sealing effect.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1 and attached Figure 2 The present embodiment provides a double-sealing structure door, including a door frame 1 and a door body 2. The door frame 1 is provided with a first sealing area and a second sealing area, and the first sealing area and the second sealing area are distributed in a stepped manner on the inner side of the door frame 1. The door body 2 is provided with a first sealing member and a second sealing member, and the first sealing member cooperates with the first sealing area for sealing, and the second sealing member cooperates with the second sealing area for sealing.

[0019] Specifically, the first sealing area and the second sealing area are both integral structures with the door frame 1, and the first sealing area is located inside the second sealing area. In the direction perpendicular to the door body 2, the first sealing area and the second sealing area are distributed front and back, and the second sealing area is located on the side close to the opening direction of the door body 2. The first sealing area and the second sealing area are respectively provided with a first card slot 3 and a second card slot 4, and the first card slot 3 and the second card slot 4 are both integral structures with the door frame 1, and the opening directions of the first card slot 3 and the second card slot 4 are both toward the door body 2. The first card slot 3 and the second card slot 4 are respectively provided with a first sealing strip 5 and a second sealing strip 6. The first sealing area and the second sealing area are distributed in a stepped manner, which effectively increases the contact area between the door frame 1 and the door body 2, and at the same time, a step structure can be formed between the door body 2 and the door frame 1. By providing the first sealing strip 5 and the second sealing strip 6 at the step, the door gap can be double-sealed perpendicular to the door gap direction, which effectively increases the sealing and heat preservation effect of the door body 2.

[0020] Preferably, the first sealing member is a pressing plate 9, which seals with the first sealing strip 5, and the second sealing member is a rubber strip A10. The door frame 1 is provided with a rubber strip B11 that cooperates with the rubber strip A10, and the rubber strip B11 seals with the second sealing strip 6 and the rubber strip A10 respectively. The rubber strip A10 and the rubber strip B11 are fixed through the connecting groove, and the rubber strip B seals with the second sealing strip and the rubber strip A respectively.

[0021] Specifically, the pressing plate 9 is an integral structure with the door body 2. After the door body 2 is closed, the pressing plate 9 can squeeze the first sealing strip 5 to form a sealing structure at the first sealing area. The side of the rubber strip B11 is provided with a protrusion, which is sealed on the surface of the second sealing strip 6. The rubber strip B11 can be sealed at the second sealing area by squeezing the rubber strip A10 and the second sealing strip 6, further increasing the sealing effect between the door body 2 and the door frame 1.

[0022] Preferably, a sealing head 16 is provided on the surface of the rubber strip A10 on one side close to the second sealing strip 6 , and a sealing groove 15 matching with the sealing head is provided on the surface of the rubber strip B, and the sealing head 16 is sealed in the sealing groove 15 .

[0023] Specifically, the sealing groove 15 is located on the side of the rubber strip B11 close to the second sealing strip 6, and the sealing groove 15 is a right-angle groove. The sealing head 16 is an integral structure with the rubber strip A10 and protrudes from the rubber strip A10. When the door body is closed, the sealing head 16 acts on the two surfaces of the right-angle sealing groove 15 to form a bidirectional sealing structure, which effectively increases the sealing effect between the rubber strip A10 and the rubber strip B11. In addition, the structure of matching the groove type and the protrusion can prevent the rubber strips from rubbing against each other during the closing process of the door body, causing the rubber strip to be lost and affecting the service life of the rubber strip.

[0024] At the same time, a cavity 17 is provided inside the rubber strip A10 and the rubber strip B11. The cavity 17 can provide a larger deformation space for the rubber strip A10 and the rubber strip B11, which is convenient for the rubber strip A10 and the rubber strip B to deform, thereby increasing the sealing effect.

[0025] Preferably, the door body 2 is further provided with a third card slot 7 , and a third sealing strip 8 is provided in the third card slot 7 .

[0026] Specifically, the first sealing strip 5, the second sealing strip 6 and the third sealing strip 8 in the present embodiment are all rubber sealing strips, the portion of the door frame 1 between the first card slot 3 and the second card slot 4 adopts a planar structure, and the third sealing strip 8 is sealed between the first card slot 3 and the second card slot 4, and can be isolated in the first sealing area and the second sealing area, thereby further increasing the sealing effect between the door frame 1 and the door body 2.

[0027] Preferably, a connection bridge 13 is provided inside the door body 2 and the door frame 1, and the connection bridge 13 is connected to the door body 2 and the door frame 1 respectively through buckles.

[0028] Specifically, the connecting bridge 13 can form a partition inside the door body 2 and the door frame 1, so that a cavity is formed inside the door body 2 and the door frame 1, which effectively reduces the heat exchange efficiency and increases the thermal insulation effect.

[0029] Preferably, a baffle 12 is provided at the edge of the door body 2, and a wind deflector 15 is provided inside the baffle.

[0030] Specifically, the baffle 12 is arranged on the outside of the door body 2, and the wind shield 15 is made of a rubber strip, which acts on the gap between the door body 2 and the door frame 1 to block the door gap, effectively reduce the airflow entering the door gap, and increase the thermal insulation effect.

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
