[0009] The door entry sealing structure provided by the present utility model has the first side plate with an extended length greater than that of the second side plate, and the third side plate with an extended length less than that of the fourth side plate. The frame and the sash frame can enclose to form a cavity for the first mounting block to install the frame seal strip and the second mounting block to install the sash seal strip. When the sash frame and the frame are closed, the frame seal strip and the sash seal strip can be pressed and abutted, thereby sealing the indoor and outdoor spaces, helping to ensure the indoor and outdoor sealing effect, and thus reducing the indoor energy loss. In addition, the pressing position of the frame seal strip and the sash seal strip is the enclosed cavity, which can provide an ideal pressing tolerance space for the frame seal strip and the sash seal strip, helping to reduce the occurrence of the situation where the seal strip fails to seal due to production and installation reasons.

[0010] Further, the frame is provided with a first card slot and a second card slot. The extending direction of the first card slot is parallel to that of the second card slot. The first card slot is arranged on one side of the first side plate facing the second side plate. The opposite ends of the frame seal strip are provided with a first clamping block and a second clamping block. The first clamping block can be clamped and fixed in the first card slot, and the second clamping block can be clamped and fixed in the second card slot.

[0011] Further, one side of the first mounting block facing the frame seal strip is provided with a first reverse buckle position, and one side of the frame seal strip facing the first mounting block is provided with a first reverse buckle. The first reverse buckle can be inserted into the first reverse buckle position.

[0012] Further, the number of both the first reverse buckle position and the first reverse buckle is at least two, and at least two first reverse buckles can be respectively inserted into the first reverse buckle positions.

[0013] Further, the frame seal strip is provided with a plurality of first buffer cavities, and the plurality of first buffer cavities are spaced on the frame seal strip.

[0014] Further, the second mounting block is provided with two third card slots, and the two third card slots are spaced on the second mounting block.

[0027] The following disclosure provides many different implementation manners or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various implementation manners and / or settings discussed.

[0028] A sealing structure for an entrance door disclosed by the present utility model is mainly applied to seal doors and windows. By reserving a cavity between the door leaf and the door frame for installing the sealing strip, a relatively wide position can be provided for installing and fixing a large-area sealing strip. When the door leaf and the door frame are closed, the large-area sealing strips of both can be pressed against each other, thereby sealing the indoor and outdoor spaces, helping to ensure the indoor and outdoor sealing effect, and thus reducing indoor energy loss.

[0029] Refer to the attached Figure 1 、attached Figure 2 、attached Figure 3, in one embodiment, the household door sealing structure includes a frame 100, a sash frame 200, a frame rubber strip 300 and a sash rubber strip 400. The frame 100 includes a first side plate 110 and a second side plate 120 which are oppositely arranged. The first side plate 110 faces the outdoor side, and the extending length of the first side plate 110 is greater than that of the second side plate 120. A first mounting block 130 is further provided between the first side plate 110 and the second side plate 120. The sash frame 200 includes a third side plate 210 and a fourth side plate 220 which are oppositely arranged. The third side plate 210 faces the outdoor side, and the extending length of the third side plate 210 is less than that of the fourth side plate 220. A second mounting block 230 is further provided between the third side plate 210 and the fourth side plate 220. The sash frame 200 is rotatably arranged on the frame 100, and the sash frame 200 can be rotated to make the second mounting block 230 parallel to the first mounting block 130. The frame rubber strip 300 is arranged on one side of the first mounting block 130 facing the second mounting block 230. The sash rubber strip 400 is arranged on one side of the second mounting block 230 facing the first mounting block 130, and the sash rubber strip 400 can be rotated with the sash frame 200 to abut against the frame rubber strip 300.

[0030] Specifically, the hardness of both the sash rubber strip 400 and the frame rubber strip 300 can be 55. A hardness of 55 is not too hard to cause a high rebound effect when the frame 100 and the sash frame 200 are closed, which affects the use experience.

[0031] As can be seen from the above, for the household door sealing structure provided by the present utility model, since the extending length of the first side plate 110 is greater than that of the second side plate 120, and the extending length of the third side plate 210 is less than that of the fourth side plate 220, the frame 100 and the sash frame 200 can enclose to form a cavity for the first mounting block 130 to install the frame rubber strip 300 and the second mounting block 230 to install the sash rubber strip 400. When the sash frame 200 and the frame 100 are closed, the frame rubber strip 300 and the sash rubber strip 400 can be pressed and abutted, thereby sealing the indoor and outdoor spaces, which helps to ensure the indoor and outdoor sealing effect and thus reduce the indoor energy loss. In addition, the pressing position of the frame rubber strip 300 and the sash rubber strip 400 is the enclosed cavity, which can provide an ideal pressing tolerance space for the frame rubber strip 300 and the sash rubber strip 400, and helps to reduce the occurrence of the situation where the rubber strip sealing fails due to production and installation reasons.

[0032] Refer to the attached Figure 4, while the frame rubber strip 300 uses a large-area rubber strip for abutting and sealing, a relatively soft rubber strip with a hardness of 55 is used. The frame rubber strip 300 is prone to displacement due to deformation during the pressing action, resulting in sealing failure. For this reason, in one embodiment, the frame 100 is provided with a first card slot 141 and a second card slot 142. The extending direction of the first card slot 141 is parallel to the extending direction of the second card slot 142. The first card slot 141 is provided on one side of the first side plate 110 facing the second side plate 120. Opposite ends of the frame rubber strip 300 are provided with a first clamping block 310 and a second clamping block 320. The first clamping block 310 can be clamped and fixed in the first card slot 141, and the second clamping block 320 can be clamped and fixed in the second card slot 142.

[0033] With the above technical solution, the first clamping block 310 and the second clamping block 320 are respectively clamped and fixed in the first card slot 141 and the second card slot 142, and the frame rubber strip 300 is fixed and limited from two opposite directions, reducing the occurrence of displacement due to deformation when the frame rubber strip 300 is pressed and abutted against the sash rubber strip 400.

[0034] In one embodiment, a first reverse buckle position 131 is provided on one side of the first mounting block 130 facing the frame rubber strip 300, and a first reverse buckle 330 is provided on one side of the frame rubber strip 300 facing the first mounting block 130. The first reverse buckle 330 can be inserted into the first reverse buckle position 131.

[0035] With the above technical solution, the first reverse buckle 330 fixes the frame rubber strip 300 by inserting into the first reverse buckle position 131. When the frame rubber strip 300 is pressed and abutted against the sash rubber strip 400, it can withstand the pressing force brought by the sash rubber strip 400, reducing the occurrence of the frame rubber strip 300 accidentally deforming and detaching from the first mounting block 130.

[0036] In one embodiment, the number of both the first reverse buckle positions 131 and the first reverse buckles 330 is at least two, and at least two first reverse buckles 330 can be respectively inserted into the first reverse buckle positions 131.

[0037] With the above technical solution, increasing the number of the first reverse buckles 330 and the first reverse buckle positions 131 helps to enhance the connection stability between the first mounting block 130 and the frame rubber strip 300.

[0038] In one embodiment, the frame rubber strip 300 is provided with a plurality of first buffer cavities 340, and the plurality of first buffer cavities 340 are spaced apart on the frame rubber strip 300.

[0039] By adopting the above technical solution, the first buffer cavity 340 can increase the deformation of the frame glue strip 300, which helps to enhance the fatigue strength of the frame glue strip 300, thereby extending the buffering time of the frame glue strip 300; in addition, multiple first buffer cavities 340 are arranged at intervals on the frame glue strip 300, which helps to ensure the structural strength of the frame glue strip 300.

[0040] The fan rubber strip 400 uses a large-area rubber strip for abutment sealing and a relatively soft rubber strip with a hardness of 55. The fan rubber strip 400 is easily deformed and displaced as the pressing action occurs, thereby causing the seal to fail. To this end, in one embodiment, the second mounting block 230 is provided with a third card slot 240, the number of the third card slot 240 is two, and the third card slot 240 is arranged at intervals on the second mounting block 230, and the fan rubber strip 400 is provided with a third card block 410, the number of the third card block 410 is two, and the two third card blocks 410 can be respectively engaged and fixed in the two third card slots 240.

[0041] By adopting the above technical solution, the two third blocks 410 are respectively engaged and fixed in the two third slots 240, and the fan rubber strip 400 is fixed and limited from two relative directions, thereby reducing the deformation and displacement when the frame rubber strip 300 and the fan rubber strip 400 are pressed and abutted.

[0042] In one embodiment, a second inverted snap-in position 231 is provided on the side of the second mounting block 230 facing the fan rubber strip 400 , and a second inverted snap-in position 420 is provided on the side of the fan rubber strip 400 facing the second mounting block 230 . The second inverted snap-in position 231 can be inserted into the second inverted snap-in position 231 .

[0043] By adopting the above technical solution, the second inverted buckle 420 fixes the fan rubber strip 400 by inserting into the second inverted buckle position 231. When the frame rubber strip 300 and the fan rubber strip 400 are pressed and abutted, it can withstand the pressing force brought by the frame rubber strip 300, thereby reducing the occurrence of accidental deformation of the fan rubber strip 400 and detachment from the second mounting block 230.

[0044] In one embodiment, the number of the second inverted buckle positions 231 and the number of the second inverted buckles 420 are both at least two, and at least two second inverted buckles 420 can be inserted into the second inverted buckle positions 231 respectively.

[0045] By adopting the above technical solution, increasing the number of the second undercuts 420 and the second undercut positions 231 helps to enhance the connection stability between the second mounting block 230 and the fan rubber strip 400.

[0046] In one embodiment, the extension length of the frame seal strip 300 decreases from close to the first side plate 110 to far away from the first side plate 110 , and the extension length of the fan seal strip 400 increases from close to the third side plate 210 to far away from the third side plate 210 .

[0047] With the above technical solution, when the frame rubber strip 300 and the sash rubber strip 400 are pressed and abutted, the pressing force gradually increases, which helps to reduce the sudden feeling of closing the door and thus improves the user's door-closing texture.

[0048] In one embodiment, the sash rubber strip 400 is provided with a second buffer cavity 430, and the extension length of the second buffer cavity 430 is arranged in an increasing manner from near the third side plate 210 to far from the third side plate 210.

[0049] With the above technical solution, the second buffer cavity 430 can increase the deformation amount of the sash rubber strip 400, which helps to improve the fatigue strength of the sash rubber strip 400 and thus prolong the buffer action time of the sash rubber strip 400.
