DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and examples.

[0017] A wind pressure resistant folding door, according to Figures 1-9 As shown, a wind-pressure-resistant folding door comprises a fixing assembly 1, a folding door leaf assembly 2 connected to the fixing assembly 1, a reinforcing track assembly 3 connected to the folding door leaf assembly 2, and a multi-point locking assembly 4 connected to the folding door leaf assembly 2; The fixing assembly 1 includes a frame 101 connected to the reinforcing track assembly 3, a concrete wall 106 connected to the frame 101, and fastening screws 105 connected to the concrete wall 106; The folding door assembly 2 includes a wall-mounted track rod 203 connected to the concrete wall 106, a cover plate 204 connected to the wall-mounted track rod 203, a second connecting member 202 connected to the wall-mounted track rod 203, and a first connecting member 201 connected to the second connecting member 202; The reinforced track assembly 3 includes a track groove 301 formed on the wall-mounted track rod 203, a roller 302 connected to the track groove 301, and a second connecting rod 303 connected to the first connecting member 201 and the second connecting member 202; The multi-point locking assembly 4 includes a first connecting seat 401 connected to the first connecting member 201 , a second connecting seat 402 connected to the first connecting member 201 , and a locking tongue 403 connected to the first connecting seat 401 .

[0018] according to Figure 1-Figure 3 The frame 101 is welded from high-strength structural steel. The surface of the first connecting member 201 and the second connecting member 202 is installed with a door panel 102. The door panel 102 is a rectangular structure. The door panel 102 is made of high-strength aluminum alloy and its surface is coated with corrosion-resistant material. The interior of the door panel 102 has a honeycomb structure.

[0019] It should be noted that high-strength structural steel has excellent yield strength and tensile strength, can provide excellent overall stiffness and load-bearing capacity, effectively resist bending and torsional stresses, can withstand huge loads without permanent deformation, and ensure the stability and safety of the structure.

[0020] according to Figure 2-Figure 3 The folding door assembly 2 also includes a fastening screw 105 connected to the concrete wall 106. The wall-mounted track rod 203 is connected to the concrete wall 106 through the fastening screw 105. A locking ring is sleeved on the outer side of the fastening screw 105. A cover plate 204 is installed on the top of the wall-mounted track rod 203, and the cover plate 204 is made of aluminum alloy.

[0021] It should be noted that the fastening screws 105 are screwed into the concrete wall 106 through pre-drilling, and the wall-mounted track rod 203 is firmly fixed to the concrete wall 106 by utilizing the bite force of the thread and the pressing force of the screw head on the wall-mounted track rod 203, thereby bearing the vertical and horizontal loads of the entire folding door assembly 2. The locking ring prevents the fastening screws 105 from loosening or falling off, and the cover plate 204 improves the aesthetics and protection.

[0022] according to Figure 3 A first connecting block 205 is installed at one end of the first connecting member 201 and the second connecting member 202, and a second connecting block 206 is installed at the other end of the first connecting member 201 and the second connecting member 202. Limiting protrusions are installed on the outer side of the first connecting block 205 and the inner side of the second connecting block 206.

[0023] It should be noted that the limiting protrusions can provide precise guidance, prevent components from being dislocated, reduce shaking during operation, and ensure the stability and safety of the door panel 102 during the opening and closing process.

[0024] according to Figure 2 The edges of the two adjacent door panels 102 are installed with sealing strips, which are in the shape of an "E" and are made of highly elastic and aging-resistant rubber. The edges of the top and bottom of the door panels 102 are installed with anti-wear blocks, which are made of high-strength and wear-resistant plastic.

[0025] It should be noted that the "E"-shaped sealing strip can fit tightly against the edges of adjacent door panels 102, effectively blocking the penetration of air, dust, noise, and light, which helps to maintain a clean, quiet, and comfortable indoor environment. The anti-wear block reduces the direct contact friction between the door panel 102 and these components during the sliding and folding process, reduces the sliding resistance, and makes the door leaf run more smoothly.

[0026] according to Figure 3-Figure 8The wall-mounted track rod 203 is integrally extruded from a high-strength, extra-thick aluminum alloy. The interior of the wall-mounted track rod 203 has a number of horizontal and vertical intersecting reinforcing ribs. The track groove 301 is T-shaped. A drainage groove is provided at the bottom of one end of the track groove 301 close to the bottom of the door panel 102. The surface of the drainage groove is coated with a hydrophobic and anti-corrosion material.

[0027] It should be noted that the high-strength and extra-thick aluminum alloy further enhances its structural load-bearing capacity and anti-deformation ability. The "T" shape greatly improves the track's resistance to bending and twisting. The drainage groove can effectively collect and discharge water droplets, condensed water or other liquid pollutants that enter the track groove 301, preventing accumulated water from corroding the track and pulley, or affecting the smooth operation of the door leaf due to accumulated water.

[0028] according to Figure 2-Figure 8 The roller 302 is made of high-strength and wear-resistant nylon material. A limit block is set inside the track groove 301. The roller 302 rolls on the inside of the limit block. The roller 302 and its connecting bracket are rotatably connected to the top of the second connecting rod 303. One end of the top and bottom of the adjacent door panel 102 is connected to the second connecting rod 303, and the other end of the top and bottom of the adjacent door panel 102 is connected to the first connecting rod 104. Buffer and shock-absorbing blocks are installed at both ends of the track groove 301 of the second connecting rod 303. The buffer and shock-absorbing blocks are made of silicone.

[0029] It should be noted that the roller 302 made of nylon has sufficient strength to withstand the weight of the door leaf and the impact force during movement, and is not easy to deform or break. The limit block accurately guides and prevents derailment, ensuring that the roller 302 rolls in the correct position in the track groove 301, preventing the roller 302 from deviating from the track or derailing during operation.

[0030] according to Figure 9 The lock tongue 403 is a cylindrical rod-shaped structure with multiple locking points. The lock tongue 403 is made of high-strength alloy. The lock tongue 403 is evenly distributed on the side of the first connecting seat 401. A number of lock holes are opened on the inner side of the second connecting seat 402. A stainless steel pipe is installed on the inner side of the lock hole. The front side of the first connecting seat 401 and the second connecting seat 402 is rotatably connected to the handle 103.

[0031] It should be noted that the high-strength alloy has extremely high hardness and toughness, can resist forced shearing, sawing or impact, and effectively prevent violent destruction. The stainless steel pipe has excellent wear resistance and can effectively prevent the inner wall of the lock hole from wearing and deforming due to long-term friction, ensuring that the lock tongue 403 is inserted smoothly and locked firmly.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
