Description

Technical Field

[0001] This utility model relates to the field of fireproof roller shutter door chain maintenance technology, and in particular to a fireproof roller shutter door chain anti-rust lubrication maintenance device. Background Technology

[0002] Fire-resistant roller shutters are a common fire safety facility in buildings, typically used in commercial buildings, factories, warehouses, and other places. They are used to prevent the spread of fire in the event of a fire. They are usually made of fire-resistant materials, such as stainless steel, aluminum alloy, or galvanized steel sheet. The roller shutters are raised and lowered by electric or manual means. When a fire occurs, the fire-resistant roller shutters will automatically descend to close the passage and prevent flames, heat, and toxic gases from spreading to other areas, thereby protecting the safety of people and property.

[0003] The chain of a fire-resistant rolling shutter door is an important component inside the door. It is connected to the electric or manual operating system of the door and its function is to transmit power through the chain, enabling the fire-resistant rolling shutter door to rise, fall, or close smoothly and reliably. However, the chain of a fire-resistant rolling shutter door will be affected by friction during long-term use. If it is not lubricated, the chain will wear down, resulting in reduced working efficiency and even breakage.

[0004] Chinese patent discloses a chain lubrication and protection device for fireproof roller shutter doors (authorization announcement number CN213298782U). This patented technology novelly incorporates an installation hole, protective pad, spherical tube, folding tube, connecting ring, lubricant bottle, bottle mouth connecting short tube, limiting ring, fixing ring, and fixing rod. This allows lubricant to be dripped from the bottom of the spherical tube onto the outside of the chain, lubricating the chain, reducing chain noise and preventing jamming, and making the rolling and stretching of the fireproof roller shutter door more stable.

[0005] However, most existing fire-resistant roller shutter doors use conduits to directly deliver lubricating oil to the chain, resulting in uneven lubrication and affecting the chain's normal operation. For example, the aforementioned prior art uses a conduit to deliver lubricating oil to the chain. In practical applications, this method leads to uneven lubrication, resulting in poor rust prevention and lubrication, thus affecting the normal use of the fire-resistant roller shutter door. Therefore, those skilled in the art provide a rust prevention and lubrication maintenance device for fire-resistant roller shutter door chains to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rust-proof lubrication and maintenance device for fireproof rolling shutter door chains, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fireproof rolling shutter door chain anti-rust lubrication and maintenance device, comprising: a liquid storage cylinder and an inlet pipe and an outlet pipe arranged from top to bottom outside the liquid storage cylinder; a connecting pipe is provided at the lower end of the outlet pipe; a connecting sleeve is provided outside the connecting pipe; and a connecting plate is connected to the lower end of the connecting pipe; outlet holes are symmetrically opened on the front surface of the connecting plate; a coating brush is inclinedly arranged on the lower surface of the connecting plate; a heating sleeve is fitted outside the liquid storage cylinder; a heat insulation sleeve is fitted outside the heating sleeve; a motor is installed on the outside of the liquid storage cylinder; a rotating shaft is connected to the drive end of the motor; stirring rods are symmetrically arranged on the outside of the rotating shaft; and a scraper is connected to one end of the stirring rod.

[0008] As a further technical solution of this utility model, the heating jacket is symmetrically provided with electric heating tubes inside, and the heat insulation jacket is provided with glass fiber material inside.

[0009] As a further technical solution of this utility model, at least six stirring rods are symmetrically arranged on the outside of the rotating shaft, and the outside of the scraper is in contact with the inside of the liquid storage cylinder.

[0010] As a further technical solution of this utility model, the connecting sleeve is threaded to the outside of the liquid outlet pipe and the connecting pipe, and a valve is provided on the outside of the liquid outlet pipe.

[0011] As a further technical solution of this utility model, the connecting plate has a channel inside, the connecting pipe is interconnected with the channel, and the liquid outlet is also interconnected with the channel.

[0012] As a further technical solution of this utility model, the heat insulation sleeve is symmetrically provided with support rods on the outside, and the lower end of the support rods is connected to an installation plate.

[0013] This utility model provides a rust-proof lubrication and maintenance device for fireproof roller shutter door chains, which has the following advantages compared with the prior art:

[0014] 1. This design provides a rust prevention and lubrication maintenance device for fireproof rolling shutter door chains. A connecting sleeve connects the connecting pipe to the liquid outlet pipe, and the connecting pipe is connected to the channel inside the connecting plate. When the valve is opened, lubricating oil can enter the connecting pipe through the liquid outlet pipe and finally be discharged outward through the liquid outlet hole onto the coating brush. By using the coating brush to contact the chain of the fireproof rolling shutter door, the lubricating oil can be evenly applied to the chain, achieving the purpose of maintenance. It is highly practical.

[0015] 2. This design provides a fireproof rolling shutter door chain anti-rust lubrication maintenance device. Through the heat insulation sleeve and heating sleeve, the lubricating oil inside the storage tank can be heated and insulated to prevent freezing in cold weather. Furthermore, the operation of the motor causes the stirring rod outside the rotating shaft to stir the lubricating oil inside the storage tank, preventing the lubricating oil from settling and separating, and ensuring the uniformity and stability of the lubricating oil.

[0026] Please see Figure 1-4 This utility model provides a technical solution for a fireproof rolling shutter door chain anti-rust lubrication and maintenance device, comprising: a liquid storage cylinder 1 and an inlet pipe 12 and an outlet pipe 11 arranged from top to bottom outside the liquid storage cylinder 1. A connecting pipe 31 is provided at the lower end of the outlet pipe 11, and a connecting sleeve 32 is provided outside the connecting pipe 31. A connecting plate 3 is connected to the lower end of the connecting pipe 31. The front surface of the connecting plate 3 has symmetrically opened outlet holes 34, and a coating brush 33 is inclinedly arranged on the lower surface of the connecting plate 3. A heating sleeve 43 is sleeved outside the liquid storage cylinder 1. A heat insulation sleeve 4 is attached, and a motor 2 is installed on the outside of the liquid storage tank 1. The drive end of the motor 2 is connected to a rotating shaft 21. A stirring rod 22 is symmetrically arranged on the outside of the rotating shaft 21. One end of the stirring rod 22 is connected to a scraper 23. This arrangement allows the lubricating oil inside the liquid storage tank 1 to be introduced into the connecting plate 3 through the liquid outlet pipe 11 and the connecting pipe 31, and discharged outward through the liquid outlet hole 34 onto the coating brush 33. The coating brush 33 can be a rubber brush. In this way, the chain can be rust-proofed and lubricated by contacting the chain through the coating brush 33, thereby improving the service life of the chain.

[0027] like Figure 3 As shown, electric heating tubes are symmetrically arranged inside the heating jacket 43, and glass fiber material is arranged inside the heat insulation jacket 4. Support rods 41 are symmetrically arranged outside the heat insulation jacket 4. The lower end of the support rod 41 is connected to the mounting plate 42. The mounting plate 42 can be installed on the fireproof roller shutter door box using bolts. The heat insulation jacket 4 can be supported by the support rod 41. In this way, the heating tubes inside the heating jacket 43 can be heated by an external power source to heat the lubricating oil inside the liquid storage cylinder 1.

[0028] like Figure 4As shown, at least six stirring rods 22 are symmetrically arranged on the outside of the rotating shaft 21, and the outside of the scraper 23 contacts the inside of the liquid storage cylinder 1. This arrangement allows the stirring rods 22 to stir the lubricating oil inside the liquid storage cylinder 1 to make the heating uniform, and the scraper 23 can clean the inner wall of the liquid storage cylinder 1.

[0029] like Figure 1 and Figure 2 As shown, the connecting sleeve 32 is threaded to the outside of the outlet pipe 11 and the connecting pipe 31. A valve 111 is provided on the outside of the outlet pipe 11. A channel is opened inside the connecting plate 3. The connecting pipe 31 communicates with the channel, and the outlet hole 34 also communicates with the channel. This arrangement uses the connecting sleeve 32 to connect the connecting pipe 31 and the outlet pipe 11. By opening the valve 111, the lubricating oil inside the storage cylinder 1 can be discharged into the channel inside the connecting plate 3. The valve 111 can be a solenoid valve. The lubricating oil in the channel can be discharged onto the coating brush 33 through the outlet hole 34 to facilitate subsequent chain lubrication.

[0030] The working principle of this utility model is as follows: When using the fireproof rolling shutter door chain anti-rust lubrication maintenance device, firstly, install the device onto the housing in the fireproof rolling shutter door via the mounting plate 42. After installation, rotate the threaded connecting sleeve 32 to connect the connecting pipe 31 to the outlet pipe 11. When it is necessary to apply lubricating oil to the fireproof rolling shutter door chain for anti-rust lubrication, open the valve 111 to allow the lubricating oil inside the storage cylinder 1 to enter the connecting pipe 31 through the outlet pipe 11, and finally discharge it outward through the outlet hole 34 onto the coating brush 33. By using the coating brush 33 to contact the chain of the fireproof rolling shutter door, the lubricating oil can be evenly applied to the chain. This invention achieves the purpose of maintenance. In cold weather, the heat insulation sleeve 4 and heating sleeve 43 can heat and insulate the lubricating oil inside the storage tank 1 to prevent freezing. The operation of the motor 2 causes the stirring rod 22 outside the rotating shaft 21 to stir the lubricating oil inside the storage tank 1, preventing the lubricating oil from settling and separating, and ensuring the uniformity and stability of the lubricating oil. It should be noted that the electrical appliances used in this invention are all externally powered and are existing products. Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the device will not be described in detail here.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
