Description

Technical Field

[0001] This utility model relates to the field of warehouse door technology, specifically a modular large warehouse door that can be quickly assembled and disassembled. Background Technology

[0002] Large warehouse doors, as core components of logistics channels in industrial buildings, are typically composed of high-strength metal curtains, drive systems, and guide rails, and are mainly used to achieve rapid passage and spatial isolation.

[0003] Traditional designs employ fixed installation structures, relying on welding or riveting processes to rigidly connect the door frame to the building structure. This requires precise positioning during installation and cannot be adjusted later. Disassembly requires cutting or destructive removal, greatly increasing maintenance costs and modification difficulties. In addition, early door designs lacked modularity, making it difficult to adapt to different wall thicknesses or quickly replace damaged parts, further limiting flexibility and maintenance efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a modular large storage door that can be quickly assembled and disassembled. The modular large storage door includes a roller shutter body 1, a column 2 fixedly installed at the lower end of the roller shutter body 1, a first movable groove 3 for accommodating the roller shutter on the inner side of the column 2, an infrared transmitter 4 fixedly installed at the upper end of the roller shutter body 1, an infrared receiver 5 fixedly installed to the left side of the infrared transmitter 4, first clamping plates 6 movably installed at both ends of the roller shutter body 1, a second clamping plate 7 movably installed at the front side of the first clamping plate 6, anti-slip pads 8 fixedly installed on the inner sides of the first clamping plate 6 and the second clamping plate 7, and second movable grooves 9 for sliding of a movable rod 10 fixedly installed at both ends of the roller shutter body 1. Movable rods 10 are fixedly installed on the inner sides of the first clamping plate 6 and the second clamping plate 7. The first clamping plate 6 and the second clamping plate 7 clamp the wall through a rotating assembly. The main body 1 of the roller shutter door serves as an integral frame to support the lifting and lowering of the door and the integration of the components. The column 2 provides vertical support through its internal structure and restricts the displacement path of the roller shutter. The first movable groove 3 accommodates the raising and lowering of the roller shutter and allows the column height to be adjusted by cutting. The infrared transmitter 4 actively emits a horizontal detection beam. The infrared receiver 5 receives the beam and judges the horizontal status of the door to trigger the indicator light 20 to display green or red light. The first clamping plate 6 and the second clamping plate 7 increase the friction with the wall through the inner anti-slip pads 8. The second movable groove 9 guides the movable rod 10 to drive the clamping plate to slide in a directional manner. The movable rod 10 connects the clamping plate and the transmission mechanism and transmits mechanical force.

[0025] The rotating assembly includes a first rack 11. The first rack 11 is fixedly connected to the inner side of the first clamping plate 6 via a movable rod 10. The second rack 12 is fixedly connected to the inner side of the second clamping plate 7 via a movable rod 10. The tooth surfaces of the first rack 11 and the second rack 12 are opposite to each other. A gear 13 meshes between the first rack 11 and the second rack 12. A drive shaft 14 is connected to the gear 13. A first bevel tooth 15 is provided at the end of the drive shaft 14 away from the gear 13. A second bevel tooth 16 meshes with the front end of the first bevel tooth 15. The first rack 11 and the second rack 12 convert the rotation of the gear 13 into bidirectional linear motion through the relative tooth surface arrangement. The gear 13 meshes with the double racks and synchronously drives the clamping plate in the opposite direction. The drive shaft 14 connects the gear set and the first bevel tooth 15 to realize power transmission. The first bevel tooth 15 and the second bevel tooth 16 change the transmission direction through perpendicular meshing.

[0026] A connecting rod 17 is provided at the end of the second bevel tooth 16 away from the first bevel tooth 15. A handle 18 is rotatably provided at the front end of the connecting rod 17. Several through holes 19 are provided on the first clamping plate 6 and the second clamping plate 7. The first clamping plate 6 and the second clamping plate 7 are fixed to the wall by bolts and through holes 19. An indicator light 20 for displaying the receiving status of the infrared receiver 5 is provided at the front end of the roller shutter door body 1. The connecting rod 17 integrates the bevel tooth group and the handle 18 to form a manual operation link. The handle 18 controls the bevel tooth transmission and adjusts the clamping force by rotating input. The through holes 19 cooperate with the bolts to penetrate the clamping plate to achieve rigid fixation with the wall. The rotating assembly as a whole converts the rotational force into the clamping action of the clamping plate. The indicator light 20 provides real-time feedback of the horizontal calibration result through red and green light signals.

[0027] Working Principle: The roller shutter door body 1 is first placed in the predetermined installation position. The upright 2 serves as a structural support, fixed to the lower end of the roller shutter door body 1 and equipped with a first movable groove 3 to enhance the overall structural stability. The infrared transmitter 4 is located at the upper end of the roller shutter door body 1, transmitting a signal to the infrared receiver 5 opposite it. If the roller shutter door body 1 is correctly placed horizontally, the infrared receiver 5 will successfully receive the infrared signal, at which point the indicator light 20 will illuminate green, indicating normal reception. If the infrared receiver 5 does not receive a signal, the indicator light 20 will illuminate red, indicating the need for adjustment. At this time, the roller shutter door body 1 can be leveled by adjusting the upright 2. During operation, the user rotates the handle 18 counterclockwise. This action is transmitted to the first bevel gear 15 via the connecting rod 17 and then to the gear 13 via the transmission shaft 14. The gear 13 converts the rotational power into the opposite linear motion of the first rack 11 and the second rack 12, causing the first clamping plate 6 and the second clamping plate 7 to clamp against the wall. The anti-slip pad 8 enhances the clamping effect and prevents slippage. Once the required tightness is achieved, the first clamping plate 6 and the second clamping plate 7 are fixed to the wall with bolts and through holes 19, completing the installation process. Disassembly is performed in the reverse direction, i.e., rotating the handle 18 clockwise to loosen the clamping plates and remove the roller shutter door body 1.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
