Description

Technical Field

[0001] The present invention relates to the technical field of building facilities, and more particularly to a modular splicing steel door that can be quickly assembled and disassembled. Background Art

[0002] Modular splicing steel doors are a type of door that is quickly assembled using standardized steel modules (such as door frames, door panels, lock components, etc.) to allow for flexible disassembly and reorganization. They are often used in places and scenarios that require frequent renovations.

[0003] Traditional modular steel doors utilize standardized steel modules with fixed dimensions. Therefore, modular steel doors must be fitted with a door opening of appropriate dimensions. Consequently, the reserved door opening dimensions are quite strict. In the event of an inappropriate door opening, the modular steel door must usually be replaced with a suitable one, increasing the cost of using the door. Installing the modular steel door using gap filling instead of replacing it requires additional time and labor, defeating the purpose of using modular steel doors in the first place.

[0007] Furthermore, side filling panels are inserted into the front and back surfaces of the side supplementary panels.

[0008] Furthermore, a corner supplementary plate is slidably inserted into the top end of the side filling plate, and the tops of the two corner supplementary plates are respectively fixedly connected with a top connecting plate and a top connecting splint.

[0009] Furthermore, a first sliding groove is provided on the surface of the top connecting splint, and a connecting column is fixedly connected to the upper surface of the top connecting plate, and the connecting column is slidably connected to the inside of the first sliding groove.

[0010] Furthermore, a support block is fixedly connected to the interior of the upper end of the side filling plate located in the front, and a corner positioning screw is rotatably connected to the interior of the support block. The top end of the corner positioning screw is threadedly inserted into the bottom end of the corner supplementary plate, and the bottom end of the corner positioning screw is fixedly connected to a first hexagonal head.

[0011] Furthermore, both ends of the top supplementary plate are slidably connected to the top side supplementary plates, and both ends of the top supplementary plate are threadedly inserted with top side positioning screws, and the ends of the two top side positioning screws that are away from each other are respectively rotatably connected to the ends of the two top side supplementary plates that are close to each other, and the ends of the two top side positioning screws that are away from each other are fixedly connected to a third hexagonal head.

[0012] Furthermore, a disassembly and assembly mechanism is provided on the surface of the door panel, and the disassembly and assembly mechanism includes a sliding rod fixedly connected to the back of the door panel, a second hinge is provided on the surface of the sliding rod, the second hinge is composed of two leaves, the two leaves of the second hinge are respectively fixedly connected with a slide plate and a hook plate, the slide plate is slidably connected to the surface of the sliding rod, and a card plate is fixedly connected to the back of one side of the door frame.

[0013] Furthermore, there are two door panels, and the two door panels are rotatably connected via a first hinge.

[0014] Furthermore, the back sides of the two door panels close to one end are respectively fixedly connected with an arc-shaped plug plate and an arc-shaped accommodating plate, the arc-shaped plug plate is inserted into the interior of the arc-shaped accommodating plate, and the upper end of the arc-shaped accommodating plate is fixedly connected with a rubber clamp.

[0015] Furthermore, the rubber clamp is sleeved on the surface of the arc-shaped inserting plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This solution uses three frame positioning screws to drive the corresponding three moving plates to move to the left, right and top respectively, so that the top supplementary plate and the two side supplementary plates are respectively against the top and both sides of the door opening, which can fix the door frame in the door opening and achieve rapid installation of the door frame.

[0019] (3) This solution allows the slide plate to move downward along the path of the sliding rod, moving the hook plate into the card plate, so that the hook plate can be hooked on the card plate to complete the rapid installation of the door panel. When the door panel is to be disassembled, the slide plate can be moved upward to separate the hook plate from the card plate, thus completing the rapid disassembly of the door panel, thereby realizing the rapid installation and disassembly of the door panel.

[0020] (4) This solution allows the two door panels to be folded together through the first hinge for easy handling and transportation. The friction between the rubber clamp and the arc-shaped insert can provide resistance when folding the door panels, reducing the speed and force of folding the door panels, thereby preventing the door panels from slipping out of the hands during folding and causing the door panels to clamp the hands or other objects of the staff, thereby improving the safety of operation and not affecting the convenience of its installation and removal.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 7 A modular splicing steel door that can be quickly installed and disassembled includes a door panel 1 and a door frame 2, wherein the door panel 1 is arranged inside the door frame 2, and a frame positioning mechanism is arranged inside the door frame 2. The frame positioning mechanism includes two side supplementary plates 319 that are slidably connected to the inside of both sides of the door frame 2, and the top of the door frame 2 is slidably connected to the top of the door frame 2, so that the top supplementary plate 303 and the two side supplementary plates 319 are respectively against the top and both sides of the door opening, so that the door frame 2 can be fixed in the door opening.

[0037] Among them, the front surfaces of the left side, right side and upper end of the door frame 2 are all provided with second sliding grooves 315, and the interiors of the three second sliding grooves 315 are slidably connected with movable plates 312, and the three movable plates 312 are respectively fixedly connected to the top supplementary plate 303 and the two side supplementary plates 319. The front surfaces of the left side, right side and upper end of the door frame 2 are all fixedly connected with support plates 313, and the surface of the support plate 313 is rotatably connected with a frame positioning screw 311, and the frame positioning screw 311 is inserted into the internal thread of the movable plate 312, and the three frame positioning screws 311 can be used to drive the corresponding three movable plates 312 to move toward the left side, right side and upper end respectively, and the end of the frame positioning screw 311 away from the support plate 313 is fixedly connected with a second hexagonal head 314.

[0038] Among them, the front and back surfaces of the side supplementary plates 319 are both inserted with side filling plates 301, the top of the side filling plates 301 is slidably inserted with a corner supplementary plate 302, the tops of the two corner supplementary plates 302 are respectively fixedly connected with a top connecting plate 309 and a top connecting splint 310, the surface of the top connecting splint 310 is provided with a first slide groove 308, the upper surface of the top connecting plate 309 is fixedly connected with a connecting column 307, the connecting column 307 is slidably connected to the inside of the first slide groove 308, and when one of the corner supplementary plates 302 moves, the other can be synchronously driven. The corner supplementary plate 302 is movable, which reduces the installation steps and does not affect the operation of other steps. The upper end of the side filling plate 301 located in the front is fixedly connected to the support block 305. The support block 305 is internally rotatably connected to the corner positioning screw 304. The top end of the corner positioning screw 304 is threadedly inserted into the bottom of the corner supplementary plate 302. The corner positioning screw 304 can be used to make the corner supplementary plate 302 rest against the top of the door opening. The bottom end of the corner positioning screw 304 is fixedly connected to the first hexagonal head 306. Using a wrench to rotate the first hexagonal head 306 can rotate the corner positioning screw 304.

[0039] Among them, the top side supplementary plates 316 are slidably connected to the inside of both ends of the top supplementary plate 303, and the corners can be filled by the top side supplementary plates 316 and the corner supplementary plates 302 to improve the airtightness of the door frame 2 after installation. The top side positioning screws 317 are threadedly inserted into the inside of both ends of the top supplementary plate 303, and the ends of the two top side positioning screws 317 that are away from each other are respectively rotatably connected to the ends of the two top side supplementary plates 316 that are close to each other. The top side supplementary plates 316 can be pressed against the sides of the corner supplementary plates 302 by the top side positioning screws 317. The ends of the two top side positioning screws 317 that are away from each other are fixedly connected to the third hexagonal head 318. The top side positioning screw 317 can be rotated by using a wrench to rotate the third hexagonal head 318.

[0040] By adopting the above technical solution, when installing the steel door, the door frame 2 is set in the door opening to be installed, and the door panel 1 is set in the door frame 2. Then, a wrench is used to rotate the second hexagonal head 314, and the three frame positioning screws 311 can be used to drive the corresponding three movable plates 312 to move to the left, right and upper ends respectively, pushing the top supplementary plate 303 and the two side supplementary plates 319 out of the door frame 2 respectively, so that the top supplementary plate 303 and the two side supplementary plates 319 are respectively pressed against the top and both sides of the door opening, and the door frame 2 can be fixed in the door opening.

[0041] After the door frame 2 is fixed, the side filling plate 301 is removed from the side supplementary plate 319, and then a wrench is used to rotate the first hexagonal head 306, so that the corner supplementary plate 302 can be driven to move upward through the corner positioning screw 304, so that the corner supplementary plate 302 is against the top of the door opening, and then a wrench is used to rotate the third hexagonal head 318, so that the top side supplementary plate 316 can be driven to extend from the top supplementary plate 303 through the top side positioning screw 317, so that the top side supplementary plate 316 is against the side of the corner supplementary plate 302, and the top side supplementary plate 316 and the corner supplementary plate 302 can be used to fill the corner that cannot be blocked by the side supplementary plate 319 and the corner supplementary plate 302, thereby greatly improving the airtightness of the door frame 2 after installation.

[0042] like Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, the disassembly and assembly mechanism is arranged on the surface of the door panel 1, and the disassembly and assembly mechanism includes a sliding rod 405 fixedly connected to the back of the door panel 1, and the surface of the sliding rod 405 is provided with a second hinge 407, and the second hinge 407 is used to realize the opening and closing of the door panel 1 during use. The second hinge 407 consists of two leaves, and the two leaves of the second hinge 407 are respectively fixedly connected with a slide plate 408 and a hook plate 409, and the slide plate 408 is slidably connected to the surface of the sliding rod 405, and the back of one side of the door frame 2 is fixedly connected with a clamping plate 406, so that the hook plate 409 is hooked on the clamping plate 406, which can complete the quick installation of the door panel 1.

[0043] Among them, the number of the door panels 1 is two, and the two door panels 1 are rotatably connected by a first hinge 401. The two door panels 1 can be folded by the first hinge 401 for easy handling and transportation. The backs of the two door panels 1 close to one end are fixedly connected with an arc-shaped plug plate 402 and an arc-shaped accommodating plate 403 respectively. The arc-shaped plug plate 402 is inserted into the interior of the arc-shaped accommodating plate 403, and the upper end of the arc-shaped accommodating plate 403 is fixedly connected with a rubber clamping ring 404. The rubber clamping ring 404 can provide resistance when folding the door panel 1, reduce the speed and force when folding the door panel 1, and improve the safety of operation. The rubber clamping ring 404 is mounted on the surface of the arc-shaped plug plate 402.

[0044] By adopting the above technical solution, after completing the installation of the door frame 2, the two door panels 1 are unfolded and set in the door frame 2, and then the slide plate 408 is moved downward along the path of the sliding rod 405, so that the hook plate 409 is moved to the card plate 406, and the hook plate 409 can be hooked on the card plate 406 to complete the rapid installation of the door panel 1, and the second hinge 407 is used to realize the opening and closing of the door panel 1 during use.

[0045] When the door panel 1 is disassembled, the slide plate 408 is moved upward to disengage the hook plate 409 from the clamping plate 406, thereby removing the door panel 1 from the door frame 2. The first hinge 401 is then used to rotate the two door panels 1, and the two door panels 1 can be folded for easy handling and transportation. During the folding process of the door panel 1, since the door panel 1 is made of steel and is relatively heavy, it is easy for the door panel 1 to slip out of the hand when folded directly, causing the door panel 1 to clamp the operator's hand or other objects. Therefore, the rubber clamp ring 404 can restrain the curved insert plate 402. The friction between the rubber clamp ring 404 and the curved insert plate 402 can provide resistance when folding the door panel 1, reduce the speed and force of folding the door panel 1, and improve the safety of the operation.

[0046] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
