A type of roller shutter door lintel

Abstract

This utility model relates to the field of roller shutter door technology and discloses a roller shutter door lintel, including a roller shutter door lintel body. A set of cleaning mechanisms is symmetrically arranged at the bottom of the roller shutter door lintel body, and a set of auxiliary mechanisms is symmetrically arranged on the surface of the cleaning mechanisms. The cleaning mechanism includes a groove frame, which is fixed to the bottom of the roller shutter door lintel body. This new solution effectively sweeps and cleans both sides of the door curtain entering the roller shutter door lintel body by setting a set of brush assemblies. At the same time, the vacuum pump body provides suction force so that the dust raised after sweeping enters the hollow brush frame through the through holes on the surface of the hollow brush frame. Then, it passes through the connection port, transmission pipe one, vacuum pump body, and transmission pipe two in sequence, and finally enters the collection box for unified collection, improving the cleaning effect and effectively preventing foreign objects and dust attached to the door curtain surface from entering the interior of the roller shutter door lintel body, thus effectively protecting the internal components of the roller shutter door lintel body.

Description

Technical Field

[0001] This utility model belongs to the field of roller shutter door technology, specifically a roller shutter door lintel. Background Technology

[0002] A roller shutter door is a door with multiple articulated door panels linked together, rotating up and down around a central roller at the top of the door within fixed tracks. The lintel provides support and a fixed foundation for the roller shutter door's roller, motor, and other components, ensuring their stable operation and smooth, stable raising and lowering of the roller shutter door.

[0003] Existing roller shutter doors easily bring foreign objects and dust adhering to the surface of the door curtain into the lintel when rolling up. This causes the foreign objects and dust to get stuck between the roller shutter door's roller shaft, guide rails, or transmission components. When the roller shutter door rises and falls, these foreign objects and dust increase the frictional resistance between the components, causing the roller shutter door to jam, make abnormal noises, or even fail to rise and fall normally. To address this, we propose a roller shutter door lintel design. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a roller shutter lintel, which effectively solves the problem that existing roller shutters easily bring foreign objects and dust attached to the surface of the shutter into the lintel when rolling up. This causes the foreign objects and dust to get stuck between the roller shutter's roller shaft, guide rail, or transmission components. When the roller shutter is raised or lowered, these foreign objects and dust increase the frictional resistance between the components, causing the roller shutter to jam, make abnormal noises, or even fail to rise or fall normally.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller shutter door lintel, including a roller shutter door lintel body, a set of cleaning mechanisms symmetrically arranged at the bottom of the roller shutter door lintel body, and a set of auxiliary mechanisms symmetrically arranged on the surface of the set of cleaning mechanisms. The cleaning mechanism includes a slot frame, the slot frame is fixedly installed at the bottom of the roller shutter door lintel body, a card plate is engaged inside the slot frame, a brush assembly is connected to the bottom of the card plate, a connection port is fixedly connected to the middle of one side of the brush assembly, a transmission pipe is connected to the end of the connection port away from the brush assembly, a vacuum pump body is connected to the end of the transmission pipe away from the connection port, a second transmission pipe is provided at the top of the vacuum pump body, and a limit frame is connected to the end of the second transmission pipe away from the vacuum pump body.

[0006] Preferably, the cleaning mechanism further includes a collection box, which is fitted into the limiting frame, and the vacuum pump body and the bottom of the collection box are provided with a support frame.

[0007] Preferably, the brush assembly is composed of a hollow brush frame and several brush clusters. The hollow brush frame has several through holes on its surface near the brush clusters, and the connection port is connected to the hollow brush frame.

[0008] Preferably, the limiting frame is inverted U-shaped, and a slot is provided at the top center of the limiting frame for connecting the transmission pipe and the collection box.

[0009] Preferably, the auxiliary mechanism includes a cylindrical frame, a set of cylindrical frames are symmetrically fixed to the surface of the slot frame, a limit rod passes through the inside of the set of cylindrical frames, a set of limit ring plates are symmetrically fixedly sleeved on the surface of the limit rod, and a spring is provided on one side of the limit ring plate.

[0010] Preferably, the card plate surface has a limiting groove that matches the end of the limiting rod, and the end of the limiting rod passes through one side of the slot frame and is matched and engaged in the limiting groove on the card plate surface.

[0011] Preferably, the limiting rod is formed into an elastic structure by a limiting ring plate, a spring, and a cylindrical frame, and the outer wall of the limiting ring plate is in contact with the inner wall of the cylindrical frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting up a set of brush components, the system effectively sweeps and cleans both sides of the curtain entering the roller shutter lintel. At the same time, the vacuum pump provides suction, causing the dust raised after sweeping to enter the hollow brush holder through the through holes on the surface of the hollow brush holder. Then, it passes through the connection port, transmission pipe one, vacuum pump body, and transmission pipe two in sequence, and finally enters the collection box for unified collection. This improves the cleaning effect and effectively prevents foreign objects and dust attached to the curtain surface from entering the interior of the roller shutter lintel, thus effectively protecting the internal components of the roller shutter lintel.

[0014] 2. By pulling the limiting rod outward, the end of the limiting rod is effectively disengaged from the inside of the clamping plate. At this time, there is no restraint between the clamping plate and the slot frame, and the clamping plate can be directly disengaged from the slot frame for quick disassembly. During installation, the clamping plate is inserted into the slot frame after pulling the limiting rod outward. Then, the limiting rod is released. Due to the spring rebound force, the end of the limiting rod quickly pops out and effectively engages with the inside of the clamping plate, thereby achieving quick positioning and fixation of the clamping plate and brush assembly.
