DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0032] like Figure 1-9 As shown, the present application provides: a door-to-top invisible door, comprising a door cover side panel, a door leaf and a wall panel, wherein the door cover side panel is connected to the side of the door opening, the wall panel is attached to the wall with the door opening formed thereon, and the front of the wall panel is flush with the front of the door leaf;

[0033] It also includes a door frame top plate, the top surface of the door frame top plate is connected to the top surface of the door opening through a connecting piece, the bottom surface of the door frame top plate is flush with the bottom surface of the ceiling keel, the door leaf is installed inside the door-shaped frame formed by the door frame top plate and the door frame side plates, and the door leaf is movably connected to one of the door frame top plate and the door frame side plates.

[0034] Among them, the connecting parts are expansion bolts, and the material of the door frame top plate is 24-layer veneer.

[0035] The present invention adjusts the height of the door frame top plate to be flush with the height of the ceiling keel, thereby forming a door-to-top invisible door. After the gypsum board is pasted on the ceiling keel and the bottom of the door frame top plate, when observed from the front, the appearance of the gap between the top of the door leaf and the door frame top plate is almost the same as the appearance of the corner between the ceiling keel and the wall. Because the top wall panel is not used, the technical problem of the gap between the door leaf and the top wall panel exposing the position of the door leaf in the traditional process is solved.

[0036] Furthermore, it is difficult to make the bottom surface of the door frame top plate flush with the bottom surface of the ceiling keel by using expansion bolts to connect the door opening and the door frame top plate. Therefore, the door frame top plate needs to be able to rise and fall slightly in the vertical direction and tilt at a slight angle.

[0037] The connecting part includes an elastic part connected to the door opening and a slot formed on the door frame top plate. The slots are located on both sides of the door frame top plate in the length direction. There are multiple slots and they are distributed side by side in the vertical direction. A protrusion is formed on the elastic part that can be inserted into any slot.

[0038] The construction workers can move the door frame top plate upwards so that the two slots are respectively engaged with the two protrusions, and then adjust the rising height of both sides of the door frame top plate in the length direction. The elastic part elastically deforms and then resets when passing through each slot, so that the protrusion is successively engaged with the inside of each slot, thereby gradually adjusting the height and inclination of the door frame top plate, and finally making the bottom surface of the door frame top plate flush with the bottom surface of the ceiling keel.

[0039] Furthermore, the present invention provides a specific embodiment of the elastic part: the elastic part is formed by a first substrate, the first substrate is a flat plate shape that fits the top surface of the door opening, the first substrate is connected to the door opening through expansion bolts, and the elastic part is symmetrically distributed on the first substrate, with the protrusions protruding outward.

[0040] The elastic member, the protrusion and the first substrate are an integrated metal member, wherein the elastic member is formed by punching and bending the first substrate through a stamping process, and the protrusion is formed by bending on the elastic member through a bending process.

[0041] Furthermore, the present invention provides a specific implementation of a card slot: the card slot is formed by a rigid member, the rigid member is in the shape of a vertical plate, the card slots are distributed side by side along the vertical direction on the rigid member, the rigid member is connected to the door frame top plate through a second substrate, the second substrate is in the shape of a flat plate and is embedded in the top surface of the door frame top plate.

[0042] The card slot, the rigid part and the second base plate are an integral metal part, and a stepped hole for embedding the rigid part and the second base plate is formed on the door frame top plate, wherein the second base plate is connected to the door frame top plate by screws, and the rigid part is punched and bent by a stamping process on the second base plate, and the rigid part is stamped twice to bend it and form a wavy surface, the valley of the wavy surface forms the card slot, and the two peaks of the wavy surface clamp the protrusion.

[0043] Furthermore, since the door cover top plate is liftable after being connected to the door opening through a connector, in order to prevent the door cover top plate from dropping after the decoration is completed, in the present invention, the ceiling keel and the door cover top plate are connected by a connecting rod that runs horizontally through the two.

[0044] Specifically, a plurality of second card slots are arranged side by side on the bottom surface of the door frame top plate, the second card slots are arranged horizontally and extend toward the ceiling keel, and a first card slot is provided on the bottom surface of the ceiling keel to form a through slot connected with the second card slot, and the connecting rod is a square wooden strip, which is embedded in the first card slot and the second card slot from bottom to top and connects the ceiling keel and the door frame top plate by nails.

[0045] Then, paste the ceiling gypsum board and door frame gypsum board on the ceiling keel and door frame top plate respectively and brush them flat. The ceiling gypsum board and door frame gypsum board can be an integrated piece. Finally, hang the door leaf to complete the decoration.

[0046] Furthermore, in order to solve the technical problem that the door frame side panels are easily separated from the sides of the door opening, in the present invention: the door frame side panels do not contact the sides of the door opening, and the door frame side panels are clamped between the sides of the door frame top panel and the sides of the door opening. In this way, as long as the door frame top panel does not separate from the door opening, the door frame side panels will not separate from the door opening.

[0047] Furthermore, in order to prevent the door leaf from protruding from the outside of the wall panel, causing the invisible door to be clearly visible, in the present invention: the wall panel covers the wall surface and passes over the two side edges of the door opening, and inwardly concave grooves are formed on both side edges of the front of the door leaf. The depth of the groove is equal to the thickness of the wall panel. When the door leaf is closed, the groove abuts against the wall panel, and at this time the front of the door leaf is flush with the front of the wall panel.

[0048] Furthermore, since the door leaf of the present invention is a door that extends from top to bottom, its weight exceeds that of a conventional door leaf. Therefore, its strength needs to be increased to prevent it from lateral warping: a plurality of reinforcing rods extending vertically and horizontally are embedded in the door leaf.

[0049] Specifically, the door leaf is formed by pressing a keel made of 24-layer veneer and a decorative panel made of wood-plastic board. An opening is reserved inside for inserting the reinforcing rod. The reinforcing rod is a 30*30*2mm square tube. The reinforcing rod is assembled into a rectangular frame shape inside the door leaf, and then a nail gun is used to connect the reinforcing rod and the keel.

[0050] A gap of about 90mm is reserved between the reinforcing rod and the top edge of the door leaf for installing the door closer. The door leaf is symmetrical on both sides, and door locks and hinges can be installed at will. Accordingly, a gap is also reserved between the reinforcing rod and the side edge of the door leaf for installing door locks and hinges.

[0051] Furthermore, in order to improve the sound insulation effect of the door leaf: the gap inside the door leaf is filled with sound insulation cotton, and the bottom of the door leaf is connected with a sound insulation strip.

[0052] Specifically, a groove is formed at the bottom of the door leaf, and the sound insulation strip is embedded in the groove, so that the sound insulation strip contacts the ground.
