In the closed door state, since the side frame 313 (such as a left side frame) of the second door frame 310 of the second door panel 300 and the side frame 213 (such as a right side frame) of the first door frame 210 of the first door panel 200 are facing each other inside and outside, the side frame 313 (such as the left side frame) of the second door frame 310 faces the second track 160 of the lower door frame 120 of the door frame 100 and has a first airtight block 410. The bottom of the first airtight block 410 is tightly attached to the top of the first fixing block 420, so that an airtight structure is formed at the bottom of the side frame 313 of the second door frame 310 to prevent the air outside the door from entering the room, thereby achieving an airtight effect.

In addition, please refer to Figures 2, 5 and 6 again. A side frame 313 (such as the left side frame) of the second door frame 310 faces the second track 160 of the door frame 110 above the door frame 100 and has the second airtight block 510. The second airtight block 510 faces the second fixed block 520 fixed to the second track 160 of the door frame 110 above the door frame 100. In the closed state, the top of the second airtight block 510 is in close contact with the bottom of the second fixed block 520 to form an upper airtight structure to prevent the air outside the door from entering the room, thereby achieving an airtight effect.

Please refer to FIG. 7, FIG. 8, and FIG. 11, which are the second embodiment of the rail-type sliding door airtight structure of the present invention, including a door frame 100, at least a first door panel 200, a second door panel 300, a lower airtight structure 400a, and an upper airtight structure 500a. The door frame 100 has an upper door frame 110 and a lower door frame 120 that are opposite to each other in vertical direction, and a left door frame 130 and a right door frame 140 that are opposite to each other in horizontal direction. The upper door frame 110 and the lower door frame 120 are provided with a first rail 150 and a second rail 160 that are opposite to each other in vertical direction. The first rail 150 and the second rail 160 are connected to each other in horizontal direction. 60, and the first track 150 is located on the outer side of the door frame 100, and the second track 160 is located on the inner side of the door frame 100. The outer periphery of the first door panel 200 has a first door frame 210, and the first door frame 210 has an upper frame 211 and a lower frame 212 respectively. The upper frame 211 and the lower frame 212 of the first door frame 210 can be moved along the first track 150 of the door frame 100. The outer periphery of the second door panel 300 has a second door frame 310, and the upper frame 311 and the lower frame 312 of the second door frame 310 can be moved along the second track 160 of the door frame 100. In the closed state, a side frame 313 (such as a left side frame) of the second door frame 310 of the second door panel 300 and a side frame 213 (such as a right side frame) of the first door frame 210 of the first door panel 200 face each other inside and outside.

Please refer to Figures 8, 9, 12 and 13 again. The lower airtight structure 400a includes a third airtight block 410a and a third fixed block 420a. A side frame 313 (such as the left side frame) of the second door frame 310 faces the second track 160 of the lower door frame 120 and is provided with the third airtight block 410a. The third fixed block 420a is fixed on the second track 160 of the lower door frame 120 of the door frame 100. The third fixed block 420a is horizontally provided with a first groove 421a. The first groove 421a is equipped with a first elastic strip 422a. In the closed state, the bottom of the third airtight block 410a is in close contact with the top of the first strip 422a.

The width of the left and right sides of the third fixed block 420a gradually shrinks away from the second door frame 310 to form two first guide parts 423a opposite to each other on the left and right. The third airtight block 410a extends a first resistance plate 411a facing the second track 160 of the lower door frame 120. When closing the door, the first resistance plate 411a is guided and resisted by the first guide part 423a, so that the second door frame 310 is further displaced to the inner side of the lower door frame 120 for close contact.

Please refer to FIG. 10, FIG. 11, FIG. 12 and FIG. 13 together. The upper airtight structure 500a includes a fourth airtight block 510a and a fourth fixing block 520a. A side frame 313 (such as a left side frame) of the second door frame 310 faces the second track 160 of the upper door frame 110 and is provided with a fourth airtight block 510a. The fourth fixing block 520a is fixed to the upper door frame 100. On the second track 160 of the door 110, the fourth fixed block 520a is horizontally provided with a second groove 521a, and the second groove 521a is equipped with a second elastic strip 522a. When the door is closed, the top of the fourth airtight block 510a is tightly attached to the bottom of the second strip 522a to form an upper airtight structure to prevent the air outside the door from entering the room, thereby achieving an airtight effect.

The width of the left and right sides of the fourth fixed block 520a gradually shrinks away from the second door frame 310 to form two second guide parts 523a opposite to each other on the left and right. The fourth airtight block 510a extends upwardly to the second track 160 of the upper door frame 110 to have a second resistance plate 511a. When closing the door, the second resistance plate 511a is guided and resisted by the second guide part 523a, so that the second door frame 310 is further displaced to the inner side of the upper door frame 110 for close contact.

With the above structure, please refer to FIG. 7, FIG. 8 and FIG. 9 again. In the closed state, since the side frame 313 (such as a left side frame) of the second door frame 310 of the second door panel 300 and the side frame 213 (such as a right side frame) of the first door frame 210 of the first door panel 200 are facing each other inside and outside, the side frame 313 (such as a left side frame) of the second door frame 310 faces the second track 160 of the door frame 120 below the door frame 100. There is a third airtight block 410a, which cooperates with a third fixed block 420a fixed on the second track 160 of the lower door frame 120 of the door frame 100, and the third fixed block 420a is horizontally provided with a first rubber strip 422a. When the door is closed, the bottom of the third airtight block 410a is tightly attached to the top of the first rubber strip 422a of the third fixed block 420a, effectively preventing the air outside the door from entering the room, so that the airtight effect can be achieved.

In addition, please refer to Figures 10 and 11. The side frame 313 (such as the left side frame) of the second door frame 310 faces the fourth airtight block 510a of the second track 160 of the door frame 110 above the door frame 100, and faces the fourth fixed block 520a fixed to the second track 160 of the door frame 110 above the door frame 100. In the closed state, the top of the fourth airtight block 510a is tightly attached to the bottom of the second rubber strip 522a of the fourth fixed block 520a to form an upper airtight structure, preventing the air outside the door from entering the room, and achieving an airtight effect.

It is worth mentioning that when closing the door, the first resisting plate 411a below the side frame 313 (such as the left side frame) of the second door frame 310 will be displaced by the first guide portion 423a of the third fixed block 420a, and the second resisting plate 511a above the side frame 313 (such as the left side frame) of the second door frame 310 will be displaced by the second guide portion 523a of the fourth fixed block 520a, so that the second door frame 310 is closer to the door frame 100 and fits tightly with the door frame 100 to achieve the purpose of airtightness.
