Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, and more specifically, to a steel sliding door with high airtightness. Background Art

[0002] A sliding door is a common type of door. It can save space, is convenient to open and close, and is suitable for various occasions. The main structure of a sliding door includes a door frame, a door panel, a slide rail, rollers, sliders, etc. Among them, the door panel can move parallel on the slide rail through the rollers and sliders to achieve the opening and closing function.

[0003] At present, most of the sliding doors on the market use sealing fringes or rubber strips to improve airtightness. However, these sealing materials are prone to aging, wear, and shedding, resulting in a decrease in airtightness. Moreover, they will increase the frictional resistance during opening and closing, affecting the smoothness of pushing and pulling.

[0004] Therefore, how to design a steel sliding door with high airtightness, which can effectively block the penetration of air and water, reduce frictional resistance, improve service life and comfort, is an urgent problem to be solved in the current technical field. Summary of the Utility Model

[0005] The utility model provides a steel sliding door with high airtightness, which is convenient for opening and closing the door.

[0006] A steel sliding door with high airtightness, including a wall, is characterized in that: there is a door opening on one side of the wall, a door frame is fixed inside the door opening, the door frame matches the door panel, a cross plate is arranged at the upper end of the door frame fixed inside the door opening, and one end of a connecting rod one is hinged to the upper end of the door frame fixed inside the door opening;

[0007] The other end of the connecting rod one is hinged to one end of a triangular plate, the triangular plate is fixedly connected to the upper middle side of one side of a frame-shaped bracket, and the lower middle part of the vertical rod of the frame-shaped bracket is fixed with another triangular plate.

[0008] As a further limitation of this technical solution, the frame-shaped bracket includes two horizontal rods and one vertical rod, and the two horizontal rods and one vertical rod form a square frame-shaped bracket with one side open and the other three sides closed.

[0009] As a further limitation of this technical solution, one end of a connecting rod two is hinged to the end of the lower triangular plate, the other end of the connecting rod two is hinged to a slider, the slider is arranged inside a slide rail, the slide rail is fixedly connected to a motor, the slide rail and the motor are fixed on one side of the wall, the lower end of the slide rail is connected to a screw rod by a bearing, the screw rod is threadedly connected to the slider, and the lower end of the screw rod is fixedly connected to the output shaft of the motor.

[0010] As a further limitation of the present technical solution, the door panel is fixedly connected to the frame-shaped bracket, a round shaft is fixed on one side of the frame-shaped bracket, the round shaft is hinged to a moving block, and the moving block is slidably connected to a limiting groove.

[0011] As a further limitation of the present technical solution, the frame-shaped bracket is an aluminum alloy bracket.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0013] The automatic lifting and swinging and tight fitting between the door panel and the door frame are realized by using components such as triangular plates, connecting rods, and sliders;

[0014] The aluminum alloy bracket is adopted as the main material of the door panel and the door frame, which has the characteristics of high strength, corrosion resistance, wear resistance, and good appearance;

[0015] The motor is adopted to drive the slider to move on the slide rail, and the precise control is realized through the threaded connection between the screw rod and the slider, which not only saves manpower but also improves the safety and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will further explain the present utility model in conjunction with the appended Figures 1 - 4 drawings and embodiments.

[0023] Embodiment 1:

[0024] A steel sliding door with high airtightness, including a wall 1. On one side of the wall 1, there is a door opening 101. Inside the door opening 101, a door frame is fixed. The door frame matches a door panel 2. At the upper end of the door frame fixed inside the door opening 101, there is a cross plate 3. One end of a connecting rod one 11 is hinged to the upper end of the door frame fixed inside the door opening 101;

[0025] The other end of the connecting rod one 11 is hinged to one end of a triangular plate 10. The triangular plate 10 is fixedly connected to the upper middle side of one side of a frame-shaped bracket 5. The middle and lower part of the vertical rod of the frame-shaped bracket 5 is fixedly connected to another triangular plate 10.

[0026] A sealing strip connected end to end is arranged inside the door frame in the door opening 101 for cooperating with the door panel 2 to achieve sealing.

[0027] The frame-shaped bracket 5 includes two horizontal rods and one vertical rod, and the two horizontal rods and one vertical rod form a square frame-shaped bracket with one side open and the other three sides closed.

[0028] One end of a connecting rod two 8 is hinged to the end of the lower triangular plate 10. The other end of the connecting rod two 8 is hinged to a slider 7. The slider 7 is arranged in a slide rail 9. The slide rail 9 is fixedly connected to a motor 6. The slide rail 9 and the motor 6 are fixed on one side of the wall 1. The lower end of the slide rail 9 is connected to a screw rod 15 by a bearing. The screw rod 15 is threadedly connected to the slider 7. The lower end of the screw rod 15 is fixedly connected to the output shaft of the motor 6.

[0029] The motor 6 is a stepping motor, which is an existing product in the prior art and will not be elaborated further.

[0030] The door panel 2 is fixedly connected to the frame-shaped bracket 5. A round shaft 14 is fixed on one side of the frame-shaped bracket 5. The round shaft 14 is hinged to a moving block 13. The moving block 13 is slidably connected to a limit groove 12.

[0031] The working principle of this embodiment is as follows:

[0032] In use, turn on the motor 6. The rotation of the output shaft of the motor 6 drives the screw 15 to rotate. The screw 15 drives the slider 7 that is threadedly connected thereto to move. The slider 7 drives the second connecting rod 8 to swing. The second connecting rod 8 drives the triangular plate 10 to swing. The triangular plate 10 drives the lower ends of the frame-shaped bracket 5 and the door panel 2 to swing inward and upward to open. The door panel 2 drives the first connecting rod 11 to swing through the triangular plate on the upper side. The door panel 2 drives the round shaft 14 to move. The round shaft 14 drives the moving block 13 to slide in the limiting groove 12. After the door panel 2 is opened, control the motor 6 to stop working. When the door panel 2 needs to be closed, control the output shaft of the motor 6 to rotate in the reverse direction to make the door panel 2 return to its original position.
