Description

Technical Field

[0001] This invention belongs to the field of rodent barrier technology, specifically referring to an adjustable rodent barrier. Background Technology

[0002] A rodent barrier is a physical barrier installed at the bottom of a door, mainly used to prevent small animals such as rats from squeezing into critical areas such as electrical rooms, kitchens, and warehouses through door gaps. The height requirements vary greatly depending on the location. Food warehouses usually require a minimum height of 60 cm, while electrical rooms usually require 40 cm. It is usually fixed to the door frame with a slot and installed with expansion nails or rivets. When needed, the rodent barrier can be slid into the slot, and when not in use, it can be removed without affecting the opening and closing of the door.

[0003] Rat barriers are usually not adjustable. Existing technology discloses a new type of rat barrier, application number CN201710294969.8. This application has a simple structure, is easy to operate, and has high sensitivity. It can realize the intelligent, automatic, and rapid opening and closing of the rat barrier, which greatly improves work efficiency. However, this application cannot know whether rats will crawl through the rat barrier after installation. It usually relies on the experience of the staff for installation, and the effect of the rat barrier is not intuitive. Therefore, there is a need to propose an adjustable rat barrier. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an adjustable rodent barrier, which effectively solves the technical problems of existing rodent barriers being difficult to adjust the rodent-blocking height and difficult to simulate the rodent-blocking effect.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an adjustable rodent barrier, including a flip-up door panel, a fixed door frame, a rodent barrier simulation structure capable of simulating the movement of a rodent, a flip-up rodent barrier component, and an electromagnetic structure. The fixed door frame is set on a plane, the flip-up door panel is hinged to the fixed door frame in two groups, the rodent barrier simulation structure is set on the fixed door frame and the flip-up door panel, the flip-up rodent barrier component is set on the fixed door frame, and the electromagnetic structure is set on the fixed door frame.

[0006] Preferably, the rodent-blocking simulation structure includes a door panel test shell, a door panel electromagnet, a door panel fluid cavity, a corrugated telescopic end, a door panel mounting side plate, a door frame test shell, a door frame electromagnet, a door frame fluid cavity, a door frame mounting side plate, and magnetorheological fluid. The door panel mounting side plate is arranged in two groups on the flip door panel. The door panel test shell is fixedly arranged on the door panel mounting side plate. The corrugated telescopic end is arranged on the door panel test shell. The door panel electromagnet is arranged on the inner wall of the door panel test shell. The door panel fluid cavity is arranged inside the door panel test shell. The door frame mounting side plate is arranged in two groups on the fixed door frame. The door frame test shell is arranged on the door frame mounting side plate. The door frame fluid cavity is arranged inside the door frame test shell. The door frame electromagnet is arranged on the inner wall of the door frame fluid cavity. A deformation-encasing bag made of plastic is provided in the door frame fluid cavity. The deformation-encasing bag is filled with magnetorheological fluid. The corrugated telescopic end enables the door panel test shell to extend at a wide angle, and it can adaptively extend and retract in conjunction with the flip door panel.

[0007] Preferably, a silicone sleeve is provided between the door panel test housing and the door frame test housing, allowing the magnetorheological fluid to move peristally within the silicone sleeve by encapsulating the deformation bag.

[0008] Furthermore, the outer wall of the door frame test housing is provided with scale lines for reading the remaining magnetorheological fluid in the door frame fluid cavity.

[0009] Furthermore, the flip-up rodent-blocking assembly includes an electric push rod, a flip-up rodent-blocking plate, a sliding height-increasing component, and a sliding height-increasing groove. The electric push rod is hinged to the fixed door frame via a base. The flip-up rodent-blocking plate is hinged to the bottom of the fixed door frame via a hinge. The output end of the electric push rod is hinged to the side wall of the flip-up rodent-blocking plate. The sliding height-increasing component is fitted and slidably disposed on the top of the flip-up rodent-blocking plate. The sliding height-increasing groove is formed on the sliding height-increasing component, so that this solution can use the sliding height-increasing grooves of multiple sets of sliding height-increasing components to stack, thereby adjusting the protection height of the rodent-blocking plate. The silicone sleeve can pass through the gap between the fixed door frame and the flip-up rodent-blocking plate when the flip-up door is closed.

[0010] Preferably, the electromagnetic structure includes a closing electromagnet and an iron sheet, with the closing electromagnet located at the top of the fixed door frame and the iron sheet located at the top of the flip-up door panel.

[0011] Furthermore, the door panel mounting side panel and the door frame mounting side panel are provided with self-adhesive labels for mounting the door panel test housing and the door frame test housing.

[0012] Furthermore, the door panel electromagnet and the magnetorheological fluid are magnetically connected, and the door frame electromagnet and the magnetorheological fluid are also magnetically connected.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides an adjustable rodent barrier, effectively solving the technical problems of existing rodent barriers being difficult to adjust in height and difficult to simulate rodent-blocking effect. This method brings the following advantages: (1) To solve the technical problem that existing rodent-blocking plates cannot simulate the rodent-blocking effect, this invention proposes a rodent-blocking simulation structure. First, the door panel test shell and the door frame test shell are respectively installed on the flip door panel and the door frame mounting side plate with adhesive. The corrugated telescopic end allows the door panel test shell to extend at a wide angle, and it can adaptively extend and retract in conjunction with the flip of the door panel. The silicone sleeve can pass through the gap between the fixed door frame and the flip rodent-blocking plate. At this time, the magnetorheological fluid and the encapsulated deformation bag are both in the fluid cavity of the door frame. When the flip door panel is closed, the silicone sleeve is still located in the gap between the fixed door frame and the flip rodent-blocking plate. At this time, there is no other substance in the silicone sleeve. When the door panel electromagnet is activated, the magnetorheological fluid tends to creep towards the door panel electromagnet through the encapsulated deformation bag in the silicone sleeve. If the gap between the fixed door frame and the flip rodent-blocking plate is not enough to allow the magnetorheological fluid to move, the magnetorheological fluid will move towards the door panel electromagnet through the encapsulated deformation bag in the silicone sleeve. If the magnetorheological fluid and the deformable bag can pass through, it indicates that the mouse cannot squeeze through the gap between the fixed door frame and the flip-up mouse barrier. If the gap between the fixed door frame and the flip-up mouse barrier allows the magnetorheological fluid and the deformable bag to pass through, the door frame electromagnet is activated. The magnetorheological fluid then tends to move through the deformable bag into the silicone sleeve towards the door frame electromagnet. The amount of magnetorheological fluid remaining in the door frame fluid cavity can be read through the scale to determine whether the mouse can pass through the flip-up mouse barrier. If the amount of magnetorheological fluid remaining in the door frame fluid cavity is less than before, the mouse can pass through the flip-up mouse barrier. If the amount of magnetorheological fluid remaining in the door frame fluid cavity remains unchanged, the mouse cannot pass through the flip-up mouse barrier. This simulates the activity of a mouse. This scheme uses the semi-fluid properties of the magnetorheological fluid to simulate the biological characteristics of a mouse and intuitively demonstrates the mouse-blocking effect.

[0014] (2) The closing electromagnet, in conjunction with the iron plate, makes the flip door panel close more stably; (3) Start the electric push rod to retract the output end of the electric push rod, which will drive the flip-up rat guard plate to flip and close, thereby achieving the purpose of blocking the rat; (4) This solution can be stacked by using the sliding height grooves of multiple sets of sliding height-increasing parts to adjust the protection height of the rodent barrier and achieve adjustable height.

[0020] like Figures 1-4 As shown, the present invention provides an adjustable rodent barrier, including a flip-up door panel 1, a fixed door frame 2, a rodent-blocking simulation structure 3, a flip-up rodent-blocking assembly 4, and an electromagnetic structure 5. The fixed door frame 2 is disposed on a plane, the flip-up door panel 1 is hinged to the fixed door frame 2 in two groups, the rodent-blocking simulation structure 3 is disposed on the fixed door frame 2 and the flip-up door panel 1, the flip-up rodent-blocking assembly 4 is disposed on the fixed door frame 2, and the electromagnetic structure 5 is disposed on the fixed door frame 2.

[0021] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the rodent-blocking simulation structure 3 includes a door panel test housing 6, a door panel electromagnet 7, a door panel fluid cavity 8, a corrugated telescopic end 9, a door panel mounting side plate 10, a door frame test housing 11, a door frame electromagnet 12, a door frame fluid cavity 13, a door frame mounting side plate 14, and a magnetorheological fluid 15. The door panel mounting side plate 10 is arranged in two groups on the flip door panel 1. The door panel test housing 6 is fixedly arranged on the door panel mounting side plate 10. The corrugated telescopic end 9 is arranged on the door panel test housing 6. The door panel electromagnet 7 is arranged on the inner wall of the door panel test housing 6. The door panel fluid cavity 8 is arranged on the door panel test housing 14. Inside the outer casing 6, the door frame mounting side plates 14 are arranged in two groups on the fixed door frame 2. The door frame test casing 11 is arranged on the door frame mounting side plates 14. The door frame fluid cavity 13 is arranged inside the door frame test casing 11. The door frame electromagnet 12 is arranged on the inner wall of the door frame fluid cavity 13. The door frame fluid cavity 13 is provided with a wrapping deformation bag 17, which is made of plastic and filled with magnetorheological fluid 15. The door panel test casing 6 can be extended at a wide angle through the corrugated telescopic end 9, and can adaptively extend and retract in conjunction with the flipping of the flipping door panel 1.

[0022] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a silicone sleeve 16 is provided between the door panel test housing 6 and the door frame test housing 11, and the magnetorheological fluid 15 can move peristally inside the silicone sleeve 16 by wrapping the deformation bag 17.

[0023] like Figure 6 and Figure 7 As shown, the outer wall of the door frame test housing 11 is provided with scale lines 18 for reading the remaining magnetorheological fluid 15 in the door frame fluid cavity 13.

[0024] like Figures 1-5 As shown, the flip-up rodent-blocking assembly 4 includes an electric push rod 19, a flip-up rodent-blocking plate 20, a sliding height-increasing component 21, and a sliding height-increasing groove 22. The electric push rod 19 is hinged to the fixed door frame 2 via a base. The flip-up rodent-blocking plate 20 is hinged to the bottom of the fixed door frame 2 via a hinge. The output end of the electric push rod 19 is hinged to the side wall of the flip-up rodent-blocking plate 20. The sliding height-increasing component 21 is fitted and slidably disposed on the top of the flip-up rodent-blocking plate 20. The sliding height-increasing groove 22 is formed on the sliding height-increasing component 21, so that this solution can use the sliding height-increasing grooves 22 of multiple sets of sliding height-increasing components 21 to be stacked, thereby adjusting the protection height of the rodent-blocking plate. The silicone sleeve 16 can pass through the gap between the fixed door frame 2 and the flip-up rodent-blocking plate 20 when the flip-up door panel 1 is closed.

[0025] like Figures 1-4As shown, the electromagnetic structure 5 includes a door-closing electromagnet 23 and an iron plate 24. The door-closing electromagnet 23 is located on the top of the fixed door frame 2, and the iron plate 24 is located on the top of the flip door panel 1.

[0026] like Figure 6 and Figure 7 As shown, the door panel mounting side plate 10 and the door frame mounting side plate 14 are provided with self-adhesive tape 25 for mounting the door panel test housing 6 and the door frame test housing 11; the door panel electromagnet 7 and the magnetorheological fluid 15 are magnetically connected, and the door frame electromagnet 12 and the magnetorheological fluid 15 are magnetically connected.

[0027] In practical use, the door panel test housing 6 and the door frame test housing 11 are first installed on the flip door panel 1 and the door frame mounting side panel 14 respectively using adhesive tape 25. The corrugated telescopic end 9 allows the door panel test housing 6 to extend at a wide angle, adapting to the flipping of the door panel 1. The silicone sleeve 16 can pass through the gap between the fixed door frame 2 and the flipping rodent barrier 20. At this time, the magnetorheological fluid 15 and the encapsulating deformation bag 17 are both in the fluid cavity 13 of the door frame. When the flipping door panel 1 is closed, the silicone sleeve 16 is still located between the fixed door frame 2 and the flipping rodent barrier 20. When the gap between the fixed door frame 2 and the flip-up mouse barrier 20 is too small, and there is no other substance inside the silicone sleeve 16, the door electromagnet 7 is activated. The magnetorheological fluid 15 then tends to creep through the deformable bag 17 inside the silicone sleeve 16 towards the door electromagnet 7. If the gap between the fixed door frame 2 and the flip-up mouse barrier 20 is insufficient for the magnetorheological fluid 15 and the deformable bag 17 to pass through, it indicates that the mouse will also be unable to squeeze through the gap. Conversely, if the gap between the fixed door frame 2 and the flip-up mouse barrier 20 is large enough for the magnetorheological fluid 15 and the deformable bag 17 to pass through... If the door frame electromagnet 12 is activated, the magnetorheological fluid 15 will tend to creep towards the door frame electromagnet 12 through the deformation bag 17 inside the silicone sleeve 16. The amount of magnetorheological fluid 15 remaining in the door frame fluid cavity 13 can be read through the scale line 18 to determine whether the mouse can pass through the flip-up mouse barrier 20. If the amount of magnetorheological fluid 15 remaining in the door frame fluid cavity 13 has decreased compared to before, the mouse can pass through the flip-up mouse barrier 20. If the amount of magnetorheological fluid 15 remaining in the door frame fluid cavity 13 remains unchanged, the mouse cannot pass through the flip-up mouse barrier 20. The rat barrier 20 is used to simulate the activity of rats. This design uses the semi-fluid properties of the magnetorheological fluid 15 to simulate the biological characteristics of rats and intuitively demonstrate the rat-blocking effect. The closing electromagnet 23, together with the iron plate 24, can make the flip door 1 close more stably. Activating the electric push rod 19 causes the output end of the electric push rod 19 to retract, thereby driving the flip rat barrier 20 to flip and close, thus achieving the purpose of blocking rats. This design can use the sliding height grooves 22 of multiple sets of sliding height-increasing parts 21 to be stacked to adjust the protective height of the rat barrier, achieving adjustability.
