Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window connection equipment, in particular to an E-shaped upside-down invisible door. Background Art
[0002] Invisible doors are daily devices used to connect two spaces and allow relative rotation between them. In some logistics centers, factories, hospitals, restaurants, catering centers, etc., these doors need to have functions such as collision resistance, wind resistance, normally open, and automatic closing. Therefore, there is an urgent need for a more optimized invisible door that meets the usage functions.
[0003] The shortcomings of existing technical products: the hinges of invisible doors are mostly installed between the rectangular tube door frame and the door body. The hinge structure is exposed when the door is opened, so the aesthetics is poor; the wind resistance of the door leaf is poor when it is closed, unless the push or pull force for opening the door is increased in exchange for stronger wind resistance. An eccentric hinge structure is also used. When the door is open, the centers of the upper and lower hinge axes are not on the same vertical line and have a certain inclination angle. The door leaf has the potential energy to return to the closed position, and automatically closes the door in turn to improve wind resistance; the existing hinges have a reset function, but do not have a normally open function, and are inconvenient to use when they need to be normally open.

[0015] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:
[0016] See also Figure 1-3According to an embodiment of the utility model, an E-type inverted invisible door comprises an invisible door 1, an upper hinge 2 is installed in the invisible door 1 by screws, a metal connector 3 is connected to the bottom of the upper hinge 2 by screws, the metal connector 3 is fixedly connected to the door body 5 by an aluminum profile, the interior of the door body 5 is an aluminum honeycomb panel, the metal connector 3 at the lower corner of the door body 5 is connected to the stop-close groove 7 by screws, the stop-close groove 7 is installed on the lower bottom plate 8 by screws, and both sides below the door body 5 are fixedly installed with a teardrop-shaped anti-collision plate 9, the upper hinge 2 comprises a slot box cover 10, the top of the slot box cover 10 is fixedly connected to the door frame cross beam reinforcement plate 11 by screws, the door frame cross beam reinforcement plate 11 is fixedly connected to the aircraft sheet 13 by screws, the bottom of the aircraft sheet 13 is fixedly connected to the slot box base 14 by screws, and the slot box base 14 is connected to the slot box cover 10. The slot box cover 10 and the door frame crossbeam reinforcement plate 11 are fixedly connected by screws, and a square hole 12 is provided in the middle of the slot box cover 10 and the door frame crossbeam reinforcement plate 11, a V-shaped groove 15 is provided in the middle of the aircraft plate 13 along the width direction and the bulge enters the square hole 12, a round hole 16 is provided in the middle of the V-shaped groove 15, and a pair of first rollers 17 are slidably connected at both ends of the V-shaped groove 15, a roller shaft 18 is inserted through the middle of the first roller 17, and a cotter pin 19 is inserted through a small hole at the end of the roller shaft 18, and the middle of the roller shaft 18 passes through the through hole at the bottom end of the shaft 20 on the bottom plate, and the shaft 20 on the bottom plate passes through the round hole 16 and the square hole 12 in sequence on the top, and the stop and close slot 7 includes an installation base plate 21, and an installation block 22 is fixedly installed on the upper middle part of the installation base plate 21 by screws, and both ends of the installation block 22 are fixedly connected to a U-shaped frame 23 by screws, and the two arms of the U-shaped frame 23 are perpendicular to the installation floor 21.
[0017] Among them, the use of aluminum profiles and metal connectors 3 makes the door leaf bright in appearance, firm in structure, and consistent in specifications, which is suitable for mechanized large-scale production. The aluminum honeycomb panel not only ensures sufficient mechanical strength, but also meets the requirement of reducing the weight of the door body 5, and there is no need to increase maintenance costs for the rust of the door panel. The door frame crossbeam reinforcement plate 11 provides sufficient bearing capacity for the door body 5. When the door body 5 is in a closed state, the first roller 17 falls into the V-groove 15, so that the arc surface of the first roller 17 contacts and is subjected to force with the V-groove 15.
[0018] In this embodiment, the second roller 24 is installed at the inner end of the U-shaped frame 23 through a rotating member, and the second roller 24 is rollingly connected to the cross-shaped recessed block 6 below.

[0019] Among them, when the door body 5 is in a closed state, the second roller 24 falls into the groove of the cross-shaped recessed block 6, so that the arc surface of the second roller 24 contacts and is subjected to force with the cross-shaped recessed block 6. When the door body 5 rotates 90 degrees, the second roller 24 slides into the groove of the cross-shaped recessed block 6 again, thereby preventing the door body 5 from resetting.
[0020] When the door 5 is opened, the first roller 17 and the second roller 24 move to the upper plane of the cross-shaped concave block 6, so that the door leaf obtains a certain amount of potential energy (potential energy), thereby generating a force opposite to the direction of the door opening, and achieving the purpose of automatic recovery. When the door body 5 is opened to 90 degrees, the second roller 24 slides into the groove of the cross-shaped concave block 6 again, thereby preventing the door body 5 from being reset.
