Description

Technical Field

[0001] The utility model relates to the technical field of folding doors, and particularly relates to a sound-insulating, heat-insulating and flame-retardant folding door. Background Art

[0002] Folding doors can be divided into two types according to different styles: side-hung folding doors and push-pull folding doors. Among them, the push-pull folding door can push each door panel to the side of the door frame, which has the characteristic of less occupied space, so it has more application scenarios. It is mainly applicable to the partition and screen uses in places such as workshops, shopping malls, office buildings, exhibition halls and home decoration. It can be installed for both internal and external doors, and can effectively play the role of dust prevention and shielding. However, general folding doors are mostly made of hollow aluminum plates or sandwich panels, and some rolling folding doors only have a layer of iron sheet, so their sound insulation and heat insulation effects are poor, and they do not have decorative effects. When a fire occurs, the door panels will be heated to a high temperature and it is difficult to open. There is a need for a new type of folding door to solve the above problems. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a sound-insulating, heat-insulating and flame-retardant folding door, which includes end plates. One side of the end plate is hinged to the door frame, and the other side of the end plate is hinged to the first one of several mutually hinged middle plates. The last middle plate is hinged to the tail plate. Corresponding half grooves are opened on the hinged sides between each plate, and the half grooves are hinged through hinge blocks. The hinge blocks communicate with the inner cavities of each plate. Each plate is provided with a charging and discharging port at the bottom, which communicates with the bottom of the inner cavity, and the charging and discharging port can be connected to a water delivery mechanism.

[0004] Furthermore, the hinge block is embedded into the notch formed by two adjacent half grooves. A group of rotary seal joints are arranged on both sides of the hinge block. The same group of rotary seal joints are respectively located on the top surface and the bottom surface of the hinge block. The top disc of the rotary seal joint is located in the inner cavity of each plate, and the bottom surface of the disc is attached to the surface of the cavity through a sealing ring.

[0005] Furthermore, a single-row rubber strip is provided on the surface of the end plate, the middle plate and the tail plate facing the door frame. When the folding door is closed, the single-row rubber strip is clamped into the double-row rubber strip on the door frame surface.

[0006] Furthermore, the water delivery mechanism includes a water pump. The water outlet pipe of the water pump is threadedly connected to one of the charging and discharging ports, the water inlet pipe of the water pump is connected to a heat dissipation water tank with a filter, and the input pipe of the heat dissipation water tank is threadedly connected to the other charging and discharging port.

[0007] Furthermore, the end plate, the middle plate and the tail plate are made of transparent materials, and decorations are provided in the cavities of each plate. The average density of the decorations is the same as that of water.

[0008] Furthermore, a handle is provided at the center of the surface of the tail plate, and door locks are embedded in the top surface and the bottom surface of the tail plate. The lock tongues of the door locks cooperate with the holes on the door frame.

[0009] The beneficial effects of the present utility model are as follows: Each door panel of the utility model is filled with clear water with a high specific heat capacity for isolation, and is sealed with single and double row rubber strips. Compared with ordinary iron hollow folding doors, it has the effects of sound insulation, heat insulation and flame retardancy. The clear water inside the folding door can be circulated through the infusion mechanism, which can further enhance the heat insulation effect and keep the clear water inside the door clean. The folding door can be made of transparent material and decorated with ornaments to improve the aesthetic effect and has a decorative function. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] As Figures 1 to 3As shown in the figure, a sound-insulating, heat-insulating and flame-retardant folding door includes an end plate 1. One side of the end plate 1 is hinged to a door frame 2, and the other side of the end plate 1 is hinged to the first one of several mutually hinged intermediate plates 3. The last intermediate plate 3 is hinged to a tail plate 4. A handle 401 is provided at the center of the surface of the tail plate 4. Door locks 10 are embedded in the top and bottom surfaces of the tail plate 4, and the lock tongues of the door locks 10 cooperate with the holes on the door frame 2. Corresponding half grooves are opened on the hinged sides between the plates, and the half grooves are hinged through hinge blocks 5. The hinge blocks 5 are embedded in the notch formed by two adjacent half grooves. A group of rotary sealing joints 501 are provided on both sides of the hinge block 5. The same group of rotary sealing joints 501 are respectively located on the top and bottom surfaces of the hinge block 5. The top discs of the rotary sealing joints 501 are located in the inner cavities of the plates, and the bottom surface of the disc is attached to the surface of the cavity through a sealing ring.

[0018] In this embodiment, single-row rubber strips 7 are provided on the surfaces of the end plate 1, the intermediate plates 3 and the tail plate 4 facing the door frame 2. When the folding door is closed, the single-row rubber strips 7 are clamped into the double-row rubber strips 8 on the frame surface of the door frame 2. Each plate is made of a transparent material, and ornaments 9 are provided in the cavities of each plate. The average density of the ornaments 9 is the same as that of water. A charging and discharging port 6 communicating with the bottom of the inner cavity is opened at the bottom of each plate. The charging and discharging port 6 can be connected to a water conveying mechanism. The water conveying mechanism includes a water pump. The water outlet pipe of the water pump is threadedly connected to one of the charging and discharging ports 6, and the water inlet pipe of the water pump is connected to a heat dissipation water tank with a filter. The input pipe of the heat dissipation water tank is threadedly connected to the other charging and discharging port 6.
