Description

Technical Field

[0001] This utility model relates to the field of lifting door technology, specifically to a modular assembly lifting door panel structure. Background Technology

[0002] Lifting doors are large industrial doors that slide vertically or curvedly along tracks. They are widely used in factories, warehouses, logistics centers, and garages. Their core functions include saving space, as the door is flush with the ceiling when open, without occupying floor or lateral space.

[0003] Currently, in order to meet the rolling function of the lifting door, the door panel adopts a segmented design and is connected by hinges. However, the door panel connected by hinges has a small bending angle and low connection strength. Therefore, a modular assembly lifting door panel structure is proposed, in which multiple first sleeves are inserted into second sleeves, and the shaft passes through the first sleeves and the second sleeves to connect the galvanized steel door panels together. This results in a high rotation angle and high connection strength. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a modular assembly lifting door panel structure, in which multiple first sleeves are inserted into second sleeves, and a shaft passes through the first and second sleeves, connecting the galvanized steel door panels together, resulting in a high rotation angle and high connection strength.

[0005] The technical solution adopted by this utility model to solve its technical problem is a modular assembly lifting door panel structure, including a door panel assembly, a connecting assembly and an anti-detachment assembly. The door panel assembly includes a galvanized steel door panel, and the top and bottom of the galvanized steel door panel are provided with convex slots. A functional core is embedded inside the galvanized steel door panel. The connecting assembly includes an upper plate and a lower plate disposed between the galvanized steel door panels. A first support plate is welded to the bottom of the upper plate, and a first rod sleeve is welded at equal intervals to the bottom of the first support plate. A second support plate is welded to the top of the lower plate, and a second rod sleeve is welded at equal intervals to the top of the second support plate. A shaft is sleeved through the second rod sleeve and the first rod sleeve.

[0006] By adopting the above technical solution, the upper and lower clamping plates are connected to the top and bottom of the galvanized steel door panel through convex grooves, and the shaft is sleeved in the first and second sleeves, so that the galvanized steel door panel can be rotated while being connected together.

[0007] Specifically, the anti-detachment component includes an upper side plate and a lower side plate disposed at both ends of the upper and lower clamping plates. A through hole is provided at one end of both the lower side plate and the upper side plate, and a shaft is sleeved through the through hole.

[0008] Specifically, threaded grooves are provided at both ends of the upper and lower clamping plates.

[0009] Specifically, the steel-plated door panel has reinforcing ribs welded at equal intervals on both sides, and the functional core is made of polyurethane foam material.

[0010] Specifically, the galvanized steel door panel has grooves at the top and bottom on both sides of the convex groove.

[0011] The beneficial effects of this utility model are: The modular assembly lifting door panel structure described in this utility model allows the upper and lower clamping plates to be inserted into convex grooves, which can fix them to the top and bottom of the galvanized steel door panel. Multiple first rod sleeves are inserted into second rod sleeves, and a shaft is inserted into the first and second rod sleeves, thereby connecting the galvanized steel door panels together. This facilitates the rotation and bending of the galvanized steel door panels, with a large bending angle and high connection strength.

[0012] The modular assembly lifting door panel structure described in this utility model uses bolts to fix the upper and lower side panels to the two ends of the upper and lower retaining plates through threaded grooves. This is used to block the upper and lower retaining plates inserted into the convex grooves, preventing them from shifting or falling off. The bottom of the upper side panel and the top of the lower side panel are fitted with shafts through through holes, allowing the upper and lower side panels to rotate without affecting the rotation of the galvanized steel door panel.

[0016] Multiple first sleeves are inserted into second sleeves, and the shaft passes through both the first and second sleeves, connecting the galvanized steel door panels together. This allows for high rotation angles and high connection strength. Figure 1-5 As shown, the modular assembly type lifting door panel structure of this utility model includes a door panel assembly 1, a connecting assembly 2 and an anti-detachment assembly 3. The door panel assembly 1 includes a galvanized steel door panel 101. The top and bottom of the galvanized steel door panel 101 are provided with convex slots 102. A functional core 104 is embedded inside the galvanized steel door panel 101. The connecting assembly 2 includes an upper clamping plate 201 and a lower clamping plate 202 disposed between the galvanized steel door panels 101. A first support plate 204 is welded to the bottom of the upper clamping plate 201. A first rod sleeve 205 is welded at equal intervals to the bottom of the first support plate 204. A second support plate 206 is welded to the top of the lower clamping plate 202. A second rod sleeve 207 is welded at equal intervals to the top of the second support plate 206. A shaft 203 is sleeved through the second rod sleeve 207 and the first rod sleeve 205.

[0017] In use, the upper plate 201 and the lower plate 202 are connected to the top and bottom of the galvanized steel door panel 101 through the convex groove 102. The shaft 203 is sleeved in the first sleeve 205 and the second sleeve 207, so that the galvanized steel door panel 101 can rotate while being connected together.

[0018] For example, such as Figure 5 As shown, the present invention also includes the anti-detachment component 3, which includes an upper side plate 301 and a lower side plate 302 disposed at both ends of the upper plate 201 and the lower plate 202. One end of the lower side plate 302 and the upper side plate 301 is provided with a through hole 304, and a shaft post 303 is sleeved through the through hole 304.

[0019] In use, the rotatable upper side plate 301 and lower side plate 302 are fixed on the upper card plate 201 and lower card plate 202, which can block the upper card plate 201 and lower card plate 202 inserted into the convex card slot 102 without affecting the rotation of the galvanized steel door panel 101.

[0020] For example, such as Figure 4 As shown, the present invention also includes threaded grooves 208 at both ends of the upper plate 201 and the lower plate 202.

[0021] In use, the threaded groove 208 makes it convenient for personnel to use bolts to fix the upper side plate 301 and the lower side plate 302 to both ends of the upper clamping plate 201 and the lower clamping plate 202.

[0022] For example, such as Figure 3 As shown, the present invention also includes reinforcing ribs 103 welded at equal intervals on both sides of the galvanized steel door panel 101, and the functional core 104 is made of polyurethane foam material.

[0023] When in use, the reinforcing rib 103 is used to improve the strength and impact resistance of the galvanized steel door panel 101, and the functional core 104 made of polyurethane foam material can improve the heat insulation and sound insulation capabilities of the galvanized steel door panel 101.

[0024] For example, such as Figure 3 As shown, the present invention also includes grooves 105 on the top and bottom of both sides of the convex groove 102 of the galvanized steel door panel 101.

[0025] When in use, the groove 105 makes it easy for personnel to embed the sealing strip into the top and bottom of the galvanized steel door panel 101.

[0026] In use, the steel-plated door panel 101 is filled with polyurethane foam material, which can improve its heat insulation and sound insulation capabilities. The reinforcing ribs 103 welded at equal intervals on both sides of the steel-plated door panel 101 can improve its strength and impact resistance. Insert the upper card plate 201 and the lower card plate 202 into the convex card slot 102 to fix them to the top and bottom of the galvanized steel door panel 101. Insert multiple first rod sleeves 205 into the second rod sleeve 207 and insert the shaft 203 into the first rod sleeve 205 and the second rod sleeve 207, so that the galvanized steel door panel 101 can be connected together and the galvanized steel door panel 101 can be rotated and bent. After the upper plate 201 and the lower plate 202 are inserted into the convex slot 102, bolts are used to fix the upper side plate 301 and the lower side plate 302 to both ends of the upper plate 201 and the lower plate 202 through the threaded groove 208. This is used to block the upper plate 201 and the lower plate 202 inserted into the convex slot 102 and prevent them from shifting or falling off. The bottom of the upper side plate 301 and the top of the lower side plate 302 are sleeved with a shaft post 303 through the through hole 304, so that the upper side plate 301 and the lower side plate 302 can rotate and will not affect the rotation of the galvanized steel door panel 101.
