Description

Technical Field

[0001] The utility model belongs to the field of shutter door structures, and in particular relates to an improved shutter door. Background Art

[0002] The main feature of the shutter door is that the door body is composed of multiple independent door panels, which can be opened and closed as a whole. However, the existing shutter door technology has the following disadvantages:

[0003] 1. Door panel material problem: Most existing shutter doors use color steel plates to make door panels. Although this material has a low cost, it has poor corrosion resistance and is prone to rust. In a humid or corrosive gas environment, the service life of the door panel will be greatly shortened, affecting the appearance and service life of the door.

[0004] 2. Connection structure problem: Existing shutter doors usually use a connection structure to assemble the door panels together to achieve the linkage effect of the door body. However, the design and manufacture of this connection structure are relatively complicated, which makes the disassembly and assembly process of a single door body very troublesome and is not conducive to maintenance and replacement.

[0005] 3. Installation positioning problem: During the installation of existing shutter doors, each door body needs to be positioned and installed independently, which makes the entire installation process very cumbersome. Not only does it increase the installation time and cost, but it may also affect the use of the door due to inaccurate positioning.

[0006] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0030] refer to Figures 1 to 4 An improved shutter door includes a plurality of door bodies arranged side by side, and adjacent door bodies overlap each other. The door body includes a door panel 10 and a door frame 20, and the door panel 10 includes an XPS board 11, and an anti-corrosion plate 12 is mounted on the front and rear surfaces of the XPS board 11. The door panel 10 has good structural thermal insulation and corrosion resistance, which is conducive to extending the service life of the door body. A first sealing strip 13 is pasted around the door panel 10, and the sealing strip is located between the door panel 10 and the door frame 20, which can prevent dust or liquid from entering the door frame 20 or the door panel 10.

[0031] The door frame 20 includes a first frame strip 21 located on the left side of the door panel 10, a second frame strip 22 located on the right side of the door panel 10, and a third frame strip 23 located on the upper and lower sides of the door panel 10, and a blocking structure 30 is arranged on the second frame strip 22. The second sealing strip 25 is mounted on the side of the second frame strip 22 facing the adjacent door body, and the second sealing strip 25 is D-shaped, which is conducive to improving the sealing between the door bodies. The third frame strip 23 located on the lower side of the door panel 10 is equipped with a hinge 24. The hinge 24 is mounted on the outer side of the third frame strip 23 located on the lower side of the door panel 10, and the inner side of the third frame strip 23 is equipped with an L-shaped pad 26. The design of the L-shaped pad 26 allows the installation of the hinge 24 to be automatically positioned. At the same time, after adding this part, the firmness of the connection of the hinge 24 can be greatly improved. The door body can rotate around the hinge 24 when in use, and the design of the blocking structure 30 can achieve the effect of opening one door body to drive all the door bodies of the improved shutter door to open, so that all the door bodies form a whole.

[0032] Preferably, the anti-corrosion plate 12, the first frame strip 21, the second frame strip 22 and the third frame strip 23 are all made of FRP material. FRP is a glass fiber reinforced plastic material with good corrosion resistance and mechanical strength.

[0033] The third frame strip 23 is provided with notches 27 on both sides, and the notches 27 are used to match the first frame strip 21 or the second frame strip 22. The traditional 45-degree angle splicing structure requires that both sides of the first frame strip 21, the second frame strip 22 and the third frame strip 23 are all processed with a 45-degree bevel, which is labor-intensive. This design allows the manufacturer to only process the upper and lower third frame strips 23 to achieve the overall assembly of the door frame 20, reducing the processing steps and improving efficiency.

[0034] Furthermore, the blocking structure 30 is provided with a first connection hole 31, the first frame bar 21 is provided with a second connection hole 32, and the first connection hole 31 of the door body and the second connection hole 32 of the adjacent door body can be connected by fastening screws. While this structure plays a fixing role, the installation of the door body is made into an open overlapping structure, which is convenient for overlapping multiple door bodies, and the difficulty of installation is greatly reduced.

[0035] The blocking structure 30 is a limiting edge, so that the limiting edge and the surface pressure of the door frame 20 corresponding to the limiting edge are evenly distributed, so as to avoid deformation of the door frame 20 or the limiting edge when the adjacent door body is driven to rotate. The limiting edge is integrally formed with the second frame strip 22, and the bottom thickness of the limiting edge is greater than the top thickness of the limiting edge, so that the door frame 20 is neat and beautiful, and the limiting edge has sufficient structural strength.

[0036] refer to Figure 5 As another embodiment of the present utility model, the blocking structure 30 is a rotary block, and the rotary block is rotatably connected to the second frame bar 22. The design of the rotary block rotation enables the door body to rotate independently, which is convenient for maintenance.

[0037] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
