Description

Technical Field

[0001] This utility model relates to the field of rotary dehumidifier technology, specifically to an aluminum alloy hinged door for a rotary dehumidifier. Background Technology

[0002] In the field of rotary dehumidifiers, the design and use of the door cavity have always been important factors affecting the ease of maintenance and performance of the equipment. Currently, most rotary dehumidifiers on the market use a pressure block type door cavity with a single-opening mechanism.

[0003] This traditional door cavity design has many limitations in practical applications. Structurally, the door cavity is usually quite heavy, mainly due to its materials and design. The heavy door makes it difficult to open, requiring operators to exert considerable force to open it during equipment inspection or maintenance, increasing the difficulty of operation and labor costs.

[0004] In terms of opening and closing methods, existing door opening and closing mechanisms are cumbersome. The pressure block design requires multiple steps when opening and closing, such as releasing the pressure block and adjusting its position. This not only wastes time but also reduces work efficiency. Moreover, the cumbersome opening and closing method increases the risk of misoperation, which may cause unnecessary damage to the equipment.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0032] like Figures 1 to 9 As shown, an aluminum alloy hinged door for a rotary dehumidifier includes a mounting plate 2 with a door cavity 1, a hinge 4 screwed to one side of the mounting plate 2, a sealing strip 12 adhered to the inside of the door cavity 1, a door panel 3 mechanically connected to the hinge 4 and placed inside the door cavity 1, a first lock body 6 screwed to one side of the door panel 3 and having a locking tongue 60, a first lock block 8 screwed to the other end of the door cavity 1 and engaging with the first lock body 6, a fixing plate 83 located at one end of the first lock block 8 and for abutting against the locking tongue 60, a first inclined surface 82 located on one side of the fixing plate 83, and a rotatable insertable... A first handle 9 is mechanically connected to a first lock body 6 at one end and a lock tongue 60; wherein, a convex surface 13 is provided on one side of the lock tongue 60, and a groove 81 for abutting against the convex surface 13 is provided at one end of the fixing plate 83; when the first handle 9 is rotated in a first direction, the convex surface 13 and the groove 81 lock together when the first handle 9 is parallel to the ground, so that the door panel 3 and the door cavity 1 are locked together; when the first handle 9 is rotated in a second direction, the convex surface 13 leaves the groove 81, the lock tongue 60 leaves the fixing plate 83 along the first inclined surface 82, and when the first handle 9 is perpendicular to the ground, the door panel 3 and the door cavity 1 are unlocked.

[0033] like Figures 1 to 9As shown, in this embodiment, rotating the first handle 9 90° counterclockwise changes it from being perpendicular to the ground to being parallel to the ground, at which point the door panel 3 closes the door cavity 1, making the door cavity 1 closed. Rotating the first handle 9 90° clockwise changes it back from being parallel to the ground to being perpendicular to the ground, and the door cavity 1 is unlocked. It is worth noting that during the rotation, after the convex surface 13 leaves the groove 81, the latch 60 will rotate on the fixed plate 83 due to the rotation of the first handle 9, causing the convex surface 13 and the fixed plate 83 to create a gap through the first inclined surface 82, thus creating a gap between the door panel 3 and the door cavity 1. However, the door panel 3 will still be locked by the first lock body 6 through the first inclined surface 82 and cannot be fully opened until the first handle 9 rotates 90° counterclockwise. Afterwards, when the first handle 9 returns from parallel to the ground to perpendicular to the ground, causing the convex surface 13 to leave the first inclined surface 82, the user can apply an outward pulling force to the first handle 9 to unlock the first lock body 6 and the first lock block 8. One end of the door panel 3 rotates through the hinge 4, thereby opening the door cavity 1. By setting the first lock body 6 and the hinge 4 to cooperate, one end of the door panel 3 is fixedly connected to the door cavity 1. When it is necessary to open the door cavity 1 for maintenance, it is not necessary to remove the entire door panel 3. Only the first lock body 6 and the first lock block 8 need to be unlocked, simplifying the opening conditions and facilitating maintenance. In addition, by setting the convex surface 13 and the first inclined surface 82 to cooperate with each other, the user can rotate the first handle 9 when unlocking to create a gap between the door panel 3 and the door cavity 1, which can effectively release some of the pressure inside the inspection door and increase protection.

[0034] Specifically, one end of the first lock body 6 is provided with an assembly cavity 62 for assembling the lock tongue 60, one end of the lock tongue 60 is provided with a sector gear 63, and one end of the assembly cavity 62 is provided with a driven gear 64 for meshing with the sector gear 63; a limiting block 68 is provided on one side of the sector gear 63, and a limiting groove 15 is provided on one side of the assembly cavity 62 for inserting into the limiting block 68; the limiting block 68 moves within the limiting groove 15, which is used to limit the movement trajectory of the driven gear 64 and the sector gear 63. By setting the limiting block 68, the driven gear 64 and the sector gear 63 are effectively prevented from disengaging during use.

[0035] Specifically, one side of the first lock body 6 is provided with a circular hole 65 with a gear shaft 14. The gear shaft 14 passes through the circular hole 65 and enters the assembly cavity 62. The driven gear 64 is provided with a connecting hole 66 for insertion with the gear shaft 14. A friction plate 67 is adhered to the gear shaft 14. The friction plate 67 is located between the connecting hole 66 and the gear shaft 14. By setting the friction plate 67, the gear can be effectively prevented from rotating and slipping on the gear shaft 14, so that the user can effectively adjust the rotation angle of the first handle 9 on the first lock body 6 through the driven gear 64. It is worth noting that in this embodiment, the material of the friction plate 67 is ceramic composite material or carbon fiber reinforced plastic.

[0036] Specifically, one side of the door panel 3 is provided with a first pad 7 for screwing with the first lock body 6. In this embodiment, the first lock body 6 is located on the side of the door panel 3 facing outward, and the first pad 7 is located on the other side of the door panel 3. The first lock body 6 is provided with several screw holes with screws, and the first pad 7 is also provided with screw holes. The screw holes on the first lock body 6 and the screw holes on the first pad 7 cooperate with each other. The door panel 3 is provided with an opening for cooperating with the screw holes. The screw passes through the opening to screw the first lock body 6 and the first pad 7 together.

[0037] Specifically, in this embodiment, a second lock body 10 is provided on the other side of the door panel 3. The first lock body 6 and the second lock body 10 have the same shape and structure. A second handle 11 is mechanically connected to the second lock body 10. The second handle 11 has the same shape and structure as the first handle 9. The first lock body 6 and the second lock body 10 are parallel to each other on the plane where the door panel 3 is located. A second pad 70 is screwed to the other end of the door panel 3. The second pad 70 is used to screw the second lock body 10, so that the second lock body 10 is fixed to the door panel 3. It should be noted that the first pad 7 and the second pad 70 have the same shape and structure. A second lock block 80 is screwed to one end of the door cavity 1. The first lock block 8 and the second lock block 80 have the same shape and structure. The first lock block 8 and the second lock block 80 are parallel to each other on the plane where the mounting plate 2 is located. In this embodiment, by setting the first lock body 6 and the second lock body 10 to cooperate with each other, the sealing structure between the door panel 3 and the door cavity 1 in this embodiment is further strengthened.

[0038] Specifically, both the door cavity 1 and the door panel 3 are made of polyurethane foam board. One end of the door panel 3 has several first screw holes 30 with the same shape and structure, and the other end of the door panel 3 has several second screw holes 31 with the same shape and structure. One end of the first lock body 6 has an opening 69 that mates with and communicates with the first screw holes 30. A hexagonal bolt 61 is inserted into the opening 69. In this embodiment, by using polyurethane foam board as the manufacturing material for the door panel 3 and the door cavity 1, the door panel 3 and the door cavity 1 have excellent heat insulation performance, while reducing the thickness of the building's external envelope structure, thereby increasing the usable indoor area. Furthermore, it has strong resistance to deformation, is not prone to cracking, and has a stable and safe finish. The first screw holes 30 have three openings... There are three openings 69, and the three openings 69 have the same shape and structure. There are also three hexagonal bolts 61, and the three hexagonal bolts 61 have the same shape and structure. Rotating the hexagonal bolts 61 in the three openings 69 causes the hexagonal bolts 61 to pass through the first screw hole 30 and through the first pad 7, thereby fixing the first lock body 6 to the door panel 3. It should be noted that since the second lock body 10 has the same shape and structure as the first lock body 6, the second lock body 10 also has three openings, and there are also hexagonal bolts in the openings. Rotating the hexagonal bolts in the three openings of the second lock body 10 causes the hexagonal bolts to pass through the second screw hole 31 on the door panel and through the second pad 70, thereby fixing the second lock body 10 to the door panel 3.

[0039] Specifically, the hinge 4 is made of aluminum alloy, and at least two hinges 4 are provided; in this embodiment, two hinges 4 are provided, and both hinges 4 are used to connect the mounting plate 2 and the door panel 3. By providing two hinges 4, the door panel 3 is hinged to the mounting plate 2, reducing the difficulty of moving the door panel 3 on the mounting plate 2, while enhancing the connection strength between the mounting plate 2 and the door panel 3, thus enhancing the usability of this embodiment. It is worth noting that the hinge 4 includes a first connecting part and a second connecting part that are mechanically connected to each other. The first connecting part is screwed to the door panel 3 using a cylindrical head hexagon socket head cap screw, and the second connecting part is screwed to the mounting plate 2 using a cylindrical head hexagon socket head cap screw.

[0040] Working principle: When closing the door cavity 1, rotate the first handle 9 clockwise so that the latch 60 is perpendicular to the ground, and rotate the door panel 3 into the door cavity 1. Rotate the first handle 9 90° clockwise. When the first handle 9 changes from perpendicular to the ground to parallel to the ground, the latch 60 is parallel to the ground, and the convex surface 13 engages with the groove 81. Then, rotate the second handle 11 in the same way. When the second handle 11 changes from perpendicular to the ground to parallel to the ground, the door panel 3 closes the door cavity 1, so that the door cavity 1 is in a closed state.

[0041] When opening the door cavity 1, rotate both the first handle 9 and the second handle 11 counterclockwise by 90° in sequence. When both the first handle 9 and the second handle 11 return from parallel to the ground to perpendicular to the ground, the door cavity 1 is in the unlocked state. The user can apply an outward pulling force to the first handle 9 or the second handle 11 to unlock the first lock body 6 and the first lock block 8, and the second lock body 10 and the second lock block 80. One end of the door panel 3 rotates through the hinge 4, thereby opening the door cavity 1. During rotation, after the convex surface 13 leaves the groove 81, the locking tongue 60 on the first handle 9 will rotate on the fixed plate 83 through the rotation of the first handle 9, so that the convex surface 13 and the fixed plate 83 will have a gap through the first inclined surface 82. The first handle 9 and the second handle 9 are in the same state, which will cause a gap to appear between the door panel 3 and the door cavity 1. However, the door panel 3 will still be locked by the first lock body 6 and the second lock body 10 through the first inclined surface 82. At this time, the rotation of the first handle 9 and the second handle 11 is stopped, and the gas in the door cavity 3 flows out from the gap, thereby producing a pressure relief effect.
