Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a bottom frame drainage structure for a side-pressure sealing door. Background Technology

[0002] Based on the opening and closing method, doors and windows can be divided into sliding, casement, and lift-type. Sliding doors and windows can form a large ventilation opening after sliding open, and are widely used in daily life. However, due to their sliding structure, sliding doors and windows have poor sealing performance, making it difficult to meet the requirements of some environments with high usage requirements.

[0003] Currently, some sliding doors and windows can achieve side-pressure sealing. When these doors and windows slide to close, they gradually move towards the door frame, and the sealing strip on the door and window presses tightly against the door frame, thereby improving the sealing performance when the door and window are closed. In existing side-pressure sealing doors and windows, double sealing is generally achieved by setting sealing strips on both the indoor and outdoor sides. However, the sealing strip on the side closer to the outside is prone to aging and water ingress. For example, in the patent document with publication number CN214697496U, the sealing between the sash and the frame is insufficient, which cannot achieve a good sealing effect. Rainwater can easily enter the guide rail position along the outer sealing strip position. If the rainwater that seeps into the guide rail position cannot be discharged in time, it will soak the guide rail assembly and affect the service life of the accessories. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a bottom frame drainage structure for a side-pressure sealing door, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A bottom frame drainage structure for a side-pressure sealed door includes a sealed door frame and a side-pressure sash. The sealed door frame is formed by a frame profile, and the side-pressure sash is formed by a sash profile. A multi-seal structure including at least one layer of water-blocking rubber strip is provided between the sash profile and the frame profile.

[0006] The frame profile includes an outer frame profile, an inner frame profile, and a heat insulation strip sandwiched between the outer frame profile and the inner frame profile. The outer frame profile is provided with a foot pedal plate facing the inner side of the sealed door frame. The sealed door frame is provided with a drainage structure that connects to the outdoor side below the foot pedal plate. The drainage structure is located on the outdoor side of the water-blocking strip.

[0007] As an improvement to the above solution, the heat insulation strip is provided with a snap-fit ​​groove in the direction of the inner side of the sealed door frame, and the bottom of the water-blocking strip is fixed in the snap-fit ​​groove.

[0008] As an improvement to the above solution, the multi-seal structure includes an outer sealing strip that snaps between the foot pedal and the fan body profile, an inner sealing strip that snaps onto the fan body profile, and a water-blocking strip that is vertically fixed to the frame profile.

[0009] As an improvement to the above solution, the drainage structure includes a drainage cavity disposed within the outer frame profile and drainage holes and seepage holes communicating with the outside. The bottom of the drainage cavity is provided with a slope sloping towards the outside. The seepage holes are disposed on the side of the drainage cavity closer to the interior. The drainage holes are disposed on the outer decorative surface of the outer frame profile, and a backflow preventer cover is provided corresponding to the location of the drainage holes.

[0010] As an improvement to the above solution, the outer frame profile is provided with a connecting part extending towards the inner side of the sealed door frame, and a shock-absorbing rubber strip is sandwiched between the end of the connecting part and the foot pedal buckle plate.

[0011] As an improvement to the above solution, the inner frame profile is provided with a fixing groove at the position facing the inner side of the sealed door frame, and an accessory profile is fixedly provided in the fixing groove. The accessory profile includes a guide rail profile and a groove profile.

[0012] As an improvement to the above solution, the fan body profile is a thermally broken profile with a clamp-shaped opening. The clamp-shaped opening near the outside is in contact with and adheres to the outer sealing strip and the water-blocking strip. The inner side of the clamp-shaped opening is engaged with the inner sealing strip.

[0013] The beneficial effects of this utility model are as follows: the side-pressure fan body and the sealed door frame body achieve triple sealing protection through the outer sealing strip, the inner sealing strip, and the water-blocking strip. Among them, the outer sealing strip, the inner sealing strip, and the water-blocking strip all come into contact with and adhere to the fan body profile during sealing to play a sealing and waterproof role. The water-blocking strip is snapped onto the heat insulation strip to form a high-level water barrier on the outside of the guide rail profile, and a drainage structure is opened in the outer frame profile to effectively prevent rainwater from entering the guide rail. The shock-absorbing strip between the foot pedal and the outer frame profile plays a shock-absorbing role. Attached Figure Description

The foot pedal plate 5 is provided on the outer frame profile 31 corresponding to the bottom of the sealing door frame 1. Decorative plates are provided on the side and top of the sealing door frame 1. The drainage structure is set below the foot pedal plate 5. The frame profile 3 is provided with a water-blocking strip 34 on the inner side of the drainage structure, which effectively prevents rainwater from seeping into the interior and guides rainwater to be discharged to the outside.

[0022] In the technical solution of the frame profile 3 of this utility model, the frame profile 3 includes an outer frame profile 31, an inner frame profile 32, and a heat insulation strip 33 sandwiched between the outer frame profile 31 and the inner frame profile 32. The outer frame profile 31 is provided with a foot pedal plate 5 in the direction of the inner side of the sealed door frame 1. The sealed door frame 1 is provided with a drainage structure that communicates with the outdoor side below the foot pedal plate 5. The drainage structure is provided on the outdoor side of the water-blocking rubber strip 34.

[0023] It should be noted that the side pressure fan body 2 is aligned with the inner frame profile 32, and a slide rail assembly is provided between the side pressure fan body 2 and the inner frame profile 32, so that the side pressure fan body 2 slides along the length direction of the inner frame profile 32. The outer frame profile 31 is provided with a drainage structure, and a water-blocking strip 34 is provided on the heat insulation strip 33 between the outer frame profile 31 and the inner frame profile 32 to serve as a separator and prevent external liquid from entering the position of the inner frame profile 32.

[0024] Furthermore, in the above scheme, the heat insulation strip 33 is provided with a snap-fit ​​groove 331 in the direction of the inner side of the sealing door frame 1, and the bottom of the water-blocking strip 34 is fixed in the snap-fit ​​groove 331.

[0025] In the technical solution of the multi-seal structure of this utility model, the multi-seal structure includes an outer sealing strip 51 that is snapped between the foot pedal plate 5 and the fan body profile 4, an inner sealing strip 41 that is snapped on the fan body profile 4, and a water-blocking strip 34 that is vertically fixed on the frame profile 3.

[0026] It should be noted that the outer sealing strip 51 is snapped onto the inner side of the foot pedal plate 5, the water-blocking strip 34 is snapped onto the heat insulation strip 33, and the inner sealing strip 41 is snapped onto the inner edge of the clamp-shaped opening 42.
