[0001] This invention relates to the field of door assembly technology, and particularly to an adjustable door crossbeam and a door body that can move accordingly. Background Technology

[0002] In modern architecture, beams are often used to enhance the structural stability of a building or between pillars. They are installed between two symmetrical pillars and can also be used for installing doors.

[0003] Chinese patent document CN106285315B discloses a door beam device with an adjustable camera, including a beam with a cavity inside. The beam's base plate has a movable groove in the middle. A connecting plate is located on the left side of the cavity and fixed to the inner wall of the cavity. An adjustment servo motor is fixed to the connecting plate. A second connecting plate is located in the cavity on the right side of the connecting plate and welded to the inner wall of the cavity. One end of an adjustment screw is hinged to the second connecting plate, and the other end is hinged to the right end face of the cavity.

A second door body component is provided on the right side of the top block. Racks are provided at both the front and rear ends of the top block. Two symmetrical straight plates are fixed at the left end of the top block. A locking post is fixed at one end of the two straight plates that are close to each other. The locking post cooperates with a locking groove. A movable door panel is fixed at the lower end of the top block.

[0015] Preferably, the second door component includes an L-shaped plate, and cleaning components are fixed at both the front and rear ends of the L-shaped plate, with both cleaning components being fixedly connected to the fixing plate.

A cleaning roller is fixed to the lower end of the gear three. A screw two is rotatably connected to the middle and right side of the top wall of the inner cavity of the grooved door panel, respectively.

[0017] Preferably, the two screws are connected by a belt, the cleaning roller and the left screw are connected by a belt, a vertical rod is fixed to the bottom wall of the inner cavity of the groove door panel, and a dust collection block is provided on the outer surface of the vertical rod and the two screws.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This device, through the structure connecting the pushing component, the stop block, the second door component, and the top block located within the cavity of the crossbeam groove, allows the movable door panel to slide between the two cleaning components, facilitating the opening of the door. The distance the movable door panel moves can be adjusted by the motor, thus adjusting the opening distance of the door. The motor drives the screw to rotate, causing the mating components to slide on the surfaces of the two fixed rods. Simultaneously, the locking pin is located within the slot cavity. Therefore, the top block and the movable door panel slide between the two cleaning components, and the two cleaning components limit the movement of the movable door panel, keeping it stable as it slides between them, thus opening the door.

[0020] This device, through the cooperation of the racks at both ends of the top block and the two cleaning components, allows the dust-collecting block and cleaning roller to wipe and clean the surface of the movable door panel as it moves to the right, keeping the surface of the movable door panel clean, and cleaning can be performed with each movement of the movable door panel; through the meshing between the rack and the gear three on the same side, the movement of the rack can drive the cleaning roller to rotate and clean the surface of the movable door panel. In addition, through the connection of the belt system, the cleaning roller and the two screws rotate together, and the dust-collecting block moves with the rotation of the screws to wipe the surface of the movable door panel and remove dust.

[0021] This device, through the cooperation of the rotating component, the starting component, and the second door component, can adjust the rotation angle of the door to adapt to different environments. By meshing gear two with gear one, the rotation angle of gear one can be adjusted when the output end of motor two rotates. Gear one is fixed to the fixed plate, and the fixed plate is fixed to the two grooved door panels, which can drive the second door component to rotate. The connecting plate on the lower side of the slide rod assembly is fixedly connected to the top block, and two locking strips hold the circular plate on the slide rod assembly. When the rotating rod rotates, it can push the slide rod assembly to rotate in the arc groove, which facilitates the adjustment of the angle of the moving door panel, so that the top block and the moving door panel rotate together with the second door component.

[0042] Specific mating components 54, such as Figure 5 As shown, the mating component 54 includes a slider 540, which is slidably connected to two fixed rods 52 and threadedly connected to a screw 53, facilitating movement of the slider 540 controlled by a motor 50. A mating block 541 is fixed to the right end of the slider 540. A slot 542 is provided on the right rear end of the mating block 541, with grooves on both the upper and lower sides of the slot 542. A mating groove 544 is provided on the left rear end of the mating block 541, which mates with the slot 542. 4. A locking block 543 is slidably connected to the inner cavity. The mating groove 544 is connected to the locking groove 542. The sliding locking block 543 can block the inner cavity space of the locking groove 542. Multiple springs 545 are fixed to the left end of the locking block 543. The multiple springs 545 are fixedly connected to the right end of the slider 540. A push block 546 is fixedly connected to the upper end of the locking block 543 through two fixed posts. The top wall of the mating groove 544 has a groove to facilitate the sliding of the two fixed posts, so that the push block 546 moves with the movement of the locking block 543.

[0043] Furthermore, such as Figure 6 As shown, the starting component 7 includes a second motor 70, which is fixedly connected to the right side wall of the inner cavity of the crossbeam slot block 1 via a mounting plate. The mounting plate is fixedly connected to the right side wall of the inner cavity of the crossbeam slot block 1, and a second gear 71 is fixed to the output end of the second motor 70.

[0044] Furthermore, such as Figure 6 — Figure 8 As shown, the rotating component 6 includes a connecting block 60 and a fixing block 61. The connecting block 60 is fixedly connected to the right side wall of the inner cavity of the crossbeam slot block 1. The fixing block 61 is fixedly connected to the motor 70 via a mounting plate. A rotating rod 63 is rotatably connected to the upper end of the fixing block 61. The upper end of the rotating rod 63 is rotatably connected to the top wall of the inner cavity of the crossbeam slot block 1. From top to bottom, the outer surface of the rotating rod 63 is provided with a rotating circular plate 68, a support plate 66, a gear 62, and a fixing plate 64. The rotating circular plate 68 is fixedly connected to the rotating rod 63, the support plate 66 is rotatably connected to the rotating rod 63, the gear 62 is fixedly connected to the rotating rod 63, and the fixing plate 64 is fixedly connected to the rotating rod 63.

[0045] The support plate 66 is fixedly connected to the left end of the crossbeam groove block 1. The upper end of the support plate 66 has a rectangular groove and an arc-shaped groove, which are connected. Specifically, as shown below... Figure 6 As shown, a sliding rod assembly 65 is slidably connected to the inner cavity of the rectangular groove. The sliding rod assembly 65 includes a sliding rod inside the rectangular groove and a circular plate fixedly connected to the sliding rod. A sliding piece 650 is fixed to the lower end of the sliding rod assembly 65, and the sliding piece 650 slides on the upper end of the fixed plate 64. A connecting plate 651 is fixed to the lower end of the sliding piece 650. The arc-shaped groove is a quarter-circle arc drawn with the rotating rod 63 as the center, which facilitates the sliding rod assembly 65 sliding in the inner cavity of the rectangular groove and then rotating in the arc-shaped groove.

[0046] In addition, the outer surface of the rotating circular plate 68 is provided with two symmetrical locking strips 67. The two locking strips 67 are fixedly connected to the rotating circular plate 68. In the initial state, the two locking strips 67 correspond to the rectangular groove at the upper end of the support plate 66. When the slide rod assembly 65 moves to the arc groove, it can clamp the circular plate. The left end of the support plate 66 is fixed with a stop block 660. The stop block 660 cooperates with the push block 546. The stop block 660 and the push block 546 are positioned opposite each other. The left end of the crossbeam groove block 1 is fixedly connected to the support plate 66 to prevent the support plate 66 from rotating. The two fixing rods 52 are fixedly connected to the left end of the support plate 66. The screw 1 53 is rotatably connected to the left end of the support plate 66. The gear 1 62 meshes with the gear 2 71. The upper end of the fixing plate 64 is provided with a sliding groove. The connecting plate 651 slides in the inner cavity of the sliding groove. Example

[0047] This embodiment provides a door that moves in sync with the aforementioned adjustable crossbeam, based on Embodiment 1.

[0048] like Figure 9 and Figure 10 As shown, a movable door includes a top block 31 fixedly installed at the lower end of a connecting plate 651. A second door component 4 is provided on the right side of the top block 31. The top block 31 and the second door component 4 are slidably connected. Both ends of the top block 31 are provided with racks 32. The two racks 32 are respectively embedded and fixed at the front and rear ends of the top block 31. Two symmetrical straight plates 33 are fixed at the left end of the top block 31. The ends of the two straight plates 33 that are close to each other are fixed with a locking post 34. The locking post 34 cooperates with the slot 542. In the initial state, the locking post 34 is located in the inner cavity of the slot 542, which facilitates the cooperating component 54 to push the movable door panel 30 to slide towards the second door component 4. The movable door panel 30 is fixed at the lower end of the top block 31.

[0049] Furthermore, such as Figure 11 As shown, the second door component 4 includes an L-shaped plate 40. The upper horizontal end of the L-shaped plate 40 cooperates with the movable door panel 30. Cleaning components 41 are fixed at both the front and rear ends of the L-shaped plate 40. The space between the two cleaning components 41 is used for the movable door panel 30 to slide. Both cleaning components 41 are fixedly connected to the fixed plate 64.

[0050] Specific cleaning components 41, such as Figure 12As shown, the cleaning component 41 includes a grooved door panel 410, a top block 31 that cooperates with the grooved door panel 410 on the same side, and a groove for the top block 31 to slide at the sliding contact position of the grooved door panel 410 and the top block 31. The grooved door panel 410 is fixed to the lower end of the fixing plate 64. A gear 3 411 is rotatably connected to the left side of the top wall of the inner cavity of the grooved door panel 410. The gear 3 411 is installed in the inner cavity of the grooved door panel 410 and will not affect the sliding of the moving door panel 30 and the top block 31 between the two grooved door panels 410. The gear 3 411 meshes with the rack 32 on the same side, so that when the top block 31 moves, it drives the gear 3 411 to rotate. A cleaning roller 412 is fixed to the lower end of the gear 3 411. A pulley is fixed to the upper side of the outer surface of the cleaning roller 412. A screw 2 413 is rotatably connected to the middle and right side of the top wall of the inner cavity of the grooved door panel 410, respectively.

[0051] The two screws 413 are connected by a belt. A double-groove pulley is fixed to the outer surface of the left screw 413, and a single-groove pulley is fixed to the outer surface of the right screw 413. The cleaning roller 412 is connected to the left screw 413 by a belt. The specific connection method is as follows: Figure 11 As shown, a vertical rod 414 is fixed to the bottom wall of the inner cavity of the recessed door panel 410. The outer surfaces of the vertical rod 414 and the two screw rods 413 are provided with a dust collection block 415. The vertical rod 414 and the dust collection block 415 are slidably connected, and the two screw rods 413 are threadedly connected to the dust collection block 415. The cleaning roller 412 and the two screw rods 413 rotate together, which allows the dust collection block 415 to move on the surface of the vertical rod 414. At the same time, the dust collection block 415 wipes the moving door panel 30 that enters between the two recessed door panels 410, keeping the surface of the moving door panel 30 clean. Holes or grooves for cleaning dust can be opened in the bottom wall of the inner cavity of the recessed door panel 410.

[0052] It should be noted that the cleaning roller 412, dust suction block 415, motor 1 50, motor 2 70 and gears in this device are all existing technologies, and their installation methods and control methods are also conventional technologies. This invention will not elaborate on them in detail.

[0053] Specific embodiments of the present invention: The present invention is an adjustable door beam and a movable door body, comprising an adjustable door beam and a movable door body that cooperates with it. When the present invention is applied, by starting the motor 50, the motor 50 drives the screw 53 fixed at the output end to rotate. The mating parts 54 on the outer surfaces of the screw 53 and the two fixed rods 52 slide towards one side of the door body part 4. When the mating parts 54 slide towards the door body part 4, the movable door panel 30 also slides towards the door body part 4 because the mating parts 54 cooperate with the locking post 34.

[0054] When the movable door panel 30 slides towards the door component 4, the locking post 34 is located in the inner cavity of the locking groove 542, and the connecting plate 651, which is fixed to the top block 31, slides in the groove at the upper end of the fixed plate 64, carrying the movable door panel 30 and the top block 31 to slide between the two cleaning components 41. The sliding rod assembly 65 slides from the inner cavity of the rectangular groove at the upper end of the support plate 66 to the inner cavity of the arc-shaped groove, such as... Figure 13 and Figure 14 As shown, when the upper circular plate of the slide rod assembly 65 is located between the two locking strips 67, the push block 546 contacts the support plate 66, and the push block 546 is pushed by the support plate 66 to move away from the support plate 66, thereby causing the locking block 543 to slide away from the support plate 66, so that the locking block 543 releases the blockage of the locking groove 542, allowing the locking post 34 to slide out from the inner cavity of the locking groove 542. The inner cavity of the locking groove 542 is matched with the diameter of the locking post 34, so that the locking post 34 can come out from the inner cavity of the locking groove 542 when rotating.

[0055] When the movable door panel 30 and the top block 31 slide between the two cleaning components 41, as Figure 15 As shown, the rack 32 meshes with the gear 411 on the same side. The movement of the rack 32 can drive the gear 411 to rotate, thereby causing the cleaning roller 412 at the lower end of the gear 411 to rotate, cleaning the movable door panel 30 that enters between the two L-shaped plates 40 and removing surface dust. In addition, under the action of the cleaning roller 412 and the two screws 413 being directly connected through the belt system, the dust suction block 415 can move on the surface of the upright 414 to wipe the surface of the movable door panel 30 and keep the surface of the movable door panel 30 clean.

[0056] When the movable door panel 30 is fully inserted between the two cleaning components 41, that is, when the slide rod assembly 65 moves to the connection point of the rectangular groove and the arc-shaped groove, then the second motor 70 is started, causing the second gear 71 at the output end of the second motor 70 to rotate. Through the engagement between the second gear 71 and the first gear 62, as... Figure 16 As shown, rotating rod 63 rotates, causing rotating disc 68 to rotate with two locking strips 67, and sliding rod assembly 65 located between the two locking strips 67 to the other side of arc groove. At the same time, fixing plate 64 rotates with the connected cleaning component 41 and the movable door panel 30 slid between the two cleaning components 41. The rotation angle is determined by the rotation of gear 2 71. Thus, movable door panel 30 and door body component 2 4 rotate together. When movable door panel 30 rotates, locking post 34 slides out from the inner cavity of locking groove 542. Then baffle 2 rotates with the rotation of movable door panel 30 and door body component 2 4.

[0057] Finally, when closing, motor 2 70 reverses, the structure on the fixed plate 64 and the slide rod assembly 65 return to the state between rotations, and at the same time, the locking post 34 returns to the inner cavity of the slot 542, motor 1 50 is started, motor 1 50 reverses, causing the mating part 54 to move towards the side of motor 1 50, the push block 546 and the stop block 660 separate, and the locking block 543 blocks the slot 542, so that the moving door panel 30 and the door body part 2 4 return to the initial state.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
