[0002] Doors are an important component of building envelope systems, with different design requirements and functions such as heat insulation, sound insulation, waterproofing, and fireproofing. Among them, wooden doors have the widest range of applications.
[0003] Traditional wooden doors are often connected by mortise and tenon joints or nails during production. However, there are still gaps between the wooden boards, which allow air to leak or water to seep into the room, affecting the door's airtightness and resulting in poor performance and reduced indoor insulation. Summary of the Invention
[0004] In view of the shortcomings of the prior art, this utility model provides a durable and sealed wooden door, which has the advantages of sealing gaps and being easy to use, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a durable and sealed wooden door, including a door frame, a limiting plate fixedly mounted on the outer wall of the door frame, a left mounting plate installed in the inner cavity of the door frame, an embedded plate movably sleeved in the inner cavity of the left mounting plate, a right mounting plate movably sleeved on the outer wall of the embedded plate, a sealing strip installed on the outer wall of the limiting plate, a sealing plate installed on the outer wall of the embedded plate, a pressure plate fixedly mounted on the outer wall of the sealing plate, a drive screw rotatably connected to the inner cavity of the door frame, a first movable seat threadedly connected to the outer wall of the drive screw, a second movable seat threadedly connected to the outer wall of the drive screw, a connecting plate rotatably connected to the outer wall of the first movable seat, an auxiliary plate rotatably connected to the outer wall of the second movable seat, a worm gear fixedly mounted on the outer wall of the drive screw, a closing plate fixedly mounted on the outer wall of the door frame, and a drive worm gear rotatably connected to the inner cavity of the closing plate.
[0006] As a preferred technical solution of this utility model: both the sealing strip and the sealing plate are made of natural rubber, and the two ends of the outer wall of the sealing strip are in contact with the outer walls of the limiting plate and the left mounting plate, respectively.
[0007] As a preferred technical solution of this utility model: both ends of the outer wall of the drive screw are equipped with external threads, and the directions of the external threads at both ends of the outer wall of the drive screw are opposite.
[0008] As a preferred technical solution of this utility model: the outer wall of the driving worm gear meshes with the outer wall of the worm wheel, and the outer wall of the connecting plate at the end away from the first moving seat is rotatably connected to the outer wall of the pressure plate.
[0009] As a preferred technical solution of this utility model: there are two pressure plates, and the two pressure plates are respectively installed at the upper and lower ends of the outer wall of the sealing plate.
[0010] As a preferred technical solution of this utility model: the outer wall of the auxiliary plate away from the second movable seat is rotatably connected to the outer wall of the pressure plate, and the two ends of the outer wall of the drive screw are rotatably connected to the inner cavity of the door frame respectively.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This durable, sealed wooden door uses a sealing plate positioned between the left mounting plate and the embedded plate, and another sealing plate positioned between the embedded plate of the right mounting plate. During the rotation of the drive screw, the pressure plate is driven, causing the pressure plate and sealing plate to fit against the gaps and seal them. Furthermore, the pressure applied to the sealing plate compresses the sealing strips between the left and right mounting plates and the limiting plate, further sealing any existing gaps and ensuring overall airtightness.
[0013] 2. This durable, sealed wooden door uses a drive worm gear connected to the inner cavity of the sealing plate. The drive worm gear drives the worm wheel, which in turn drives the drive screw to rotate. This applies pressure between the pressure plate and the sealing plate, making the sealing plate fit more tightly with the gap, thus better sealing the gap. This process only requires rotating the drive worm gear, which is very convenient. Attached Figure Description

[0021] Please see Figure 1 - Figure 5 A durable, sealed wooden door includes a door frame 1. A limiting plate 2 is fixedly mounted on the outer wall of the door frame 1. A left mounting plate 3 is installed in the inner cavity of the door frame 1. An embedded plate 4 is movably sleeved in the inner cavity of the left mounting plate 3. A right mounting plate 5 is movably sleeved on the outer wall of the embedded plate 4. A sealing strip 6 is installed on the outer wall of the limiting plate 2. A sealing plate 7 is installed on the outer wall of the embedded plate 4. A pressure plate 8 is fixedly mounted on the outer wall of the sealing plate 7. A drive screw 9 is rotatably connected to the inner cavity of the door frame 1. A first movable seat 10 is threadedly connected to the outer wall of the drive screw 9. A second movable seat 11 is threadedly connected to the outer wall of the drive screw 9. A connecting plate 12 is rotatably connected to the outer wall of the first movable seat 10. An auxiliary plate 13 is rotatably connected to the outer wall of the second movable seat 11. A worm gear 14 is fixedly mounted on the outer wall of the drive screw 9. A closing plate 16 is fixedly mounted on the outer wall of the door frame 1. A drive worm gear 15 is rotatably connected to the inner cavity of the closing plate 16.
[0022] In the above structure, the limiting plate 2 set on the outer wall of the door frame 1, and the left mounting plate 3, the embedded plate 4, and the right mounting plate 5 set in the inner cavity of the door frame 1, under the action of the left mounting plate 3, the embedded plate 4, and the right mounting plate 5, can close the inner cavity of the door frame 1 and form a complete wooden door.
[0023] In a preferred embodiment, both the sealing strip 6 and the sealing plate 7 are made of natural rubber, and the two ends of the outer wall of the sealing strip 6 are in contact with the outer walls of the limiting plate 2 and the left mounting plate 3, respectively.
[0024] In the above structure, by setting the limiting plate 2 on the outer wall of the left mounting plate 3 and the right mounting plate 5, pressure is applied to the outer wall of the left mounting plate 3, the embedded plate 4, and the right mounting plate 5 by the pressure plate 8 and the sealing plate 7, so that the outer wall of the left mounting plate 3 and the right mounting plate 5 fits against the inner wall of the limiting plate 2 and squeezes the sealing strip 6, causing the outer wall of the sealing strip 6 to deform, thereby better sealing the gap between the left mounting plate 3 and the right mounting plate 5 and the limiting plate 2.
[0025] In a preferred embodiment, both ends of the outer wall of the drive screw 9 are provided with external threads, and the directions of the external threads at both ends of the outer wall of the drive screw 9 are opposite.
[0026] In the above structure, the external threads provided at both ends of the outer wall of the drive screw 9 drive the second moving seat 11 and the first moving seat 10 when the drive screw 9 rotates, thereby changing the angle between the outer walls of the connecting plate 12 and the auxiliary plate 13, thus applying pressure to the outer walls of the pressure plate 8 and the sealing plate 7, so that the outer wall of the sealing plate 7 fits better into the gap between the left mounting plate 3 and the embedded plate 4 and the right mounting plate 5, thereby sealing the gap.
[0027] In a preferred embodiment: the outer wall of the drive worm 15 meshes with the outer wall of the worm wheel 14, and the outer wall of the connecting plate 12 at the end away from the first moving seat 10 is rotatably connected to the outer wall of the pressure plate 8.
[0028] In the above structure, the drive worm 15 is rotatably connected in the inner cavity of the closed plate 16, and the outer wall of the drive worm 15 meshes with the outer wall of the worm wheel 14. When the drive worm 15 is rotated, it can drive the worm wheel 14, thereby causing the worm wheel 14 to drive the rotation of the drive screw 9, and thus driving the first moving seat 10 and the second moving seat 11 during the rotation of the drive screw 9.
[0029] In a preferred embodiment, there are two pressure plates 8, and the two pressure plates 8 are respectively installed at the upper and lower ends of the outer wall of the sealing plate 7.
[0030] In the above structure, the pressure plates 8 set at the upper and lower ends of the outer wall of the sealing plate 7 rotate the driving worm 15, thereby driving the worm wheel 14 during the rotation of the driving worm 15, which in turn drives the rotation of the driving screw 9, and thus drives the second moving seat 11 and the connecting plate 12 during the rotation of the driving screw 9.
[0031] In a preferred embodiment: the outer wall of the auxiliary plate 13 away from the second movable seat 11 is rotatably connected to the outer wall of the pressure plate 8, and the two ends of the outer wall of the drive screw 9 are rotatably connected to the inner cavity of the door frame 1 respectively.
[0032] In the above structure, by using the auxiliary plate 13 provided on the outer wall of the second movable seat 11, when the drive screw 9 rotates, the second movable seat 11 and the first movable seat 10 can be driven respectively, and the first movable seat 10 and the second movable seat 11 can be brought closer to each other, thereby changing the angle between the connecting plate 12 and the auxiliary plate 13, thereby applying pressure to the pressure plate 8, so that the outer wall of the sealing plate 7 can better fit into the gap between the outer walls of the left mounting plate 3 and the embedded plate 4.
[0033] Working Principle: During the use of the above equipment, when the door frame 1 is in use, the left mounting plate 3, the embedded plate 4, and the right mounting plate 5 are respectively installed in the inner cavity of the door frame 1, so that the left mounting plate 3, the embedded plate 4, and the right mounting plate 5 form a complete door panel. Then, by rotating the drive worm 15, the outer wall of the drive worm 15 meshes with the outer wall of the worm wheel 14. Under the action of the drive worm 15, the worm wheel 14 is driven, which in turn causes the drive screw 9 to rotate under the action of the worm wheel 14. During the rotation of the drive screw 9, the second moving seat 11 and the first moving seat 10 are driven, so that the outer walls of the first moving seat 10 and the second moving seat 11 move along the outer wall of the drive screw 9. By changing the angle between the connecting plate 12 and the auxiliary plate 13, pressure is applied to the outer wall of the pressure plate 8, and the force is applied to the sealing plate 7 under the action of the pressure plate 8. This causes the sealing plate 7 to fit into the gap between the outer walls of the left mounting plate 3, the embedded plate 4, and the right mounting plate 5, thus better sealing the gap between them and ensuring better sealing. When the sealing plate 7 applies pressure to the outer walls of the left mounting plate 3, the embedded plate 4, and the right mounting plate 5, it also causes the left mounting plate 3 and the right mounting plate 5 to squeeze the sealing strip 6, thereby deforming the outer wall of the sealing strip 6 and better sealing the gap.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
