DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figure 1-5 As shown, a rat-proof air-locking door comprises a door frame, a door curtain 11 and a winding assembly for the retractable door curtain 11, wherein the winding assembly is mounted on the top of the door frame, and the top of the door curtain 11 is mounted on the winding assembly. The door curtain 11 further comprises two first rubber strips 12 and two second rubber strips 13 corresponding to the positions of the first rubber strips 12. The two first rubber strips 12 and the second rubber strips 13 are respectively located at the top and bottom of the door curtain 11, and the first rubber strips 12 are fixed to the door frame; the top and bottom of the door frame are respectively fixed with an upper servo electric cylinder 14 and a lower servo electric cylinder 15, and the two second rubber strips 13 are respectively fixed to the output end of the upper servo electric cylinder 14 and the output end of the lower servo electric cylinder 15; the upper servo cylinder 14 and the lower servo cylinder 15 can drive the second rubber strips 13 to move The first rubber strip 12 on the other side of the door curtain 11 cooperates with the first rubber strip 12 to clamp the door curtain 11; the door frame includes two column rails 21, a base frame 23 and a supporting square tube 22, the base frame 23 is fixed to the bottom of the column rail 21, the supporting square tube 22 is fixed to the top of the column rail 21, the upper servo electric cylinder 14 is fixed to the supporting square tube 22, and the lower servo motor 32 is fixed to the base frame 23; the winding assembly includes two wall panels 31, a motor 32 and a roller 33, the wall panel 31 is bolted to the top of the column rail 21, the motor 32 is fixed to the wall panel 31, the roller 33 is rotatably connected between the two wall panels 31, the output end of the motor 32 and the roller 33 are connected by a belt 34, and the top of the door curtain 11 is mounted on the roller 33;

[0024] When the staff needs to close the door, they only need to press the servo control box that controls the motor 32. The motor 32 drives the roller 33 through the belt 34, and the roller 33 unwinds the door curtain 11. The door curtain 11 will fall until the bottom pocket of the door curtain 11 touches the ground. At this time, the servo electric cylinder control box will receive the door closing signal, and the upper servo electric cylinder 14 and the lower servo electric cylinder 15 will push the second rubber bead 13, so that the first rubber bead 12 and the second rubber bead 13 sandwich the door curtain 11. At this time, the door curtain 11 is in a sealed state, which can prevent dust and small animals such as mice from entering the machine room.

[0025] To open the door, the operator simply presses the servo control box that controls the motor 32. The servo electric cylinder control box receives the door-opening signal, and the upper and lower servo electric cylinders 14 and 15 retract the second rubber bead 13. The first and second rubber bead 12 and 13 separate, releasing the door curtain 11 that was previously sandwiched between them. The motor 32 that controls the door curtain 11 receives the signal, and the door curtain 11 opens upward to the previously set opening height. At this point, the operator can enter and exit normally.

[0026] Further, such as Figure 2-3 As shown, a mouse guard 41 is detachably mounted on the base frame 23 , and a baffle 42 is detachably mounted on the bottom of the column track 21 . The mouse guard 41 and the baffle 42 are respectively located on both sides of the bottom of the door curtain 11 .

[0027] In this embodiment, when moving items into a room, the mouse guard 41 is welded with a square tube to form a base frame 23, allowing people to walk and move items without interference. The mouse guard 41 and baffle 42 are removable when needed. The load-bearing design saves time and effort when disassembling each time you enter or exit the room. The simple structure also facilitates assembly and disassembly.

[0028] Further, such as Figure 4-5 As shown, a counterweight steel plate 5 is fixed to the bottom of the door curtain 11 .

[0029] In this embodiment, preferably, a 5 cm long and 6 mm thick counterweight steel plate 5 is fixed to the bottom end of the door curtain 11 to act as a counterweight, so that the door curtain 11 remains taut and upright.

[0030] Further, such as Figure 1-5 As shown, a cover plate 61 is bolted to the wall panel 31 , a side sealing plate 62 is bolted to the sides of the two wall panels 31 away from each other, and a column sealing plate 63 is bolted to the column track 21 .

[0031] Further, such as Figure 2 As shown, the column track 21 is fixed with a polymer track 7 .

[0032] In this embodiment, the two sides of the door curtain 11 slide from the polymer track 7, and the polymer track 7 is on the column track 21, which better ensures the effectiveness of the door curtain 11 in terms of dustproof, mouse-blocking and other functions.

[0033] Furthermore, the distance between the bottom of the door curtain 11 and the ground is less than 1 cm.

[0034] Working principle: when the staff needs to close the door, they only need to press the servo control box of the control motor 32. The motor 32 drives the roller 33 through the belt 34, and the roller 33 unwinds the door curtain 11. The door curtain 11 will fall until the bottom pocket of the door curtain 11 touches the ground. At this time, the servo electric cylinder control box will receive the door closing signal, and the upper servo electric cylinder 14 and the lower servo electric cylinder 15 will push the second rubber strip 13, so that the first rubber strip 12 and the second rubber strip 13 will sandwich the door curtain 11 in the middle. At this time, the door curtain 11 is in The sealed state can prevent dust and small animals such as mice from entering the machine room. When opening the door, the staff only needs to press the servo control box of the control motor 32. At this time, the servo electric cylinder control box will first receive the door opening signal, and the upper servo electric cylinder 14 and the lower servo electric cylinder 15 will retract the second rubber bead 13. The first rubber bead 12 and the second rubber bead 13 will separate, and the door curtain 11 that was originally sandwiched in the middle will be released. The motor 32 that controls the door curtain 11 receives the signal and the door curtain 11 opens upward to the previously set opening height. At this time, staff can enter and exit normally.

[0035] When moving items into the room, the rat guard 41 is internally welded from square tubes to form a base frame 23, allowing people to walk and carry items without interference. The rat guard 41 and baffle 42 are removable when needed. The load-bearing design saves time disassembling each time you enter or exit the room. The simple structure facilitates assembly and disassembly. A 5cm long, 6mm thick counterweight steel plate 5 is fixed to the bottom of the door curtain 11 to act as a counterweight, keeping the door curtain 11 taut and upright. The two sides of the door curtain 11 slide on polymer rails 7, which are mounted on the column tracks 21, further ensuring the effectiveness of the door curtain 11's dustproof and rat-blocking functions.
