Description

Technical Field

[0001] This invention belongs to the field of building rodent control technology, and relates to a single-sided flip-up doorway rodent barrier and its method. Background Technology

[0002] In water conservancy projects, auxiliary buildings, power distribution rooms, and material warehouses typically require rodent barriers at doorways to prevent rodents from entering and gnawing on cables and damaging equipment, thus ensuring the safe operation of the facilities. Existing rodent barriers mainly suffer from three types of defects: First, traditional fixed rodent barriers are mostly integral plug-in structures, usually more than 50cm high. When people pass through or move equipment, they need to lift and disassemble them repeatedly, which is cumbersome and inefficient. In addition, they can easily become obstacles to passage in emergency evacuation scenarios, which does not meet the emergency evacuation requirements of fire doors. Secondly, existing electric flip-up rodent barriers rely on motors, sensors, and power supply systems, which are complex in structure and have a high failure rate. In humid and dusty industrial environments, they are prone to problems such as circuit corrosion and sensor malfunction. Furthermore, they cannot work properly when the power is off, resulting in insufficient reliability. At the same time, electric structures are costly and difficult to maintain. Third, most flip-up rodent barriers do not have one-way limits and can be pushed from both the inside and outside, allowing rodents to push open the barrier from the outside and enter, resulting in insufficient reliability in preventing rodents. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a single-sided flip-up doorway rodent barrier and method, which is purely mechanical and passive, single-sided flip-up, and has both reliable rodent prevention and unobstructed passage capabilities.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a single-sided flip-up doorway rat barrier, which includes a left column, a right column, a flip-up rat barrier, a one-way flipping assembly, and a catch; the left column and the right column are symmetrically fixed to the walls on both sides of the doorway, and the two ends of the flip-up rat barrier are rotatably connected to the lower part of the two columns through the one-way flipping assembly; the one-way flipping assembly restricts the flip-up rat barrier to flip in one direction only along the opening direction of the door to a horizontal ground-facing state; the catch is set on the inside of the column, and when the flip-up rat barrier is in the vertical rat-blocking state, the catch is engaged in the positioning groove on the side of the flip-up rat barrier to achieve vertical positioning of the flip-up rat barrier.

[0005] The one-way flipping assembly includes a flipping assembly housing, a flipping assembly inner shaft, and a return spring; the flipping assembly housing is fixed to the inside of the column by flipping assembly fixing bolts.

[0006] The inner shaft of the flip assembly is inserted inside the flip assembly housing and is fixedly connected to the end of the flip rodent guard plate.

[0007] The reset spring is fitted on the outside of the inner shaft of the flip assembly, with one end connected to the outer shell of the flip assembly and the other end connected to the inner shaft of the flip assembly, providing a restoring force for the flipped mouse guard to rotate to a vertical position.

[0008] The rodent-blocking post is L-shaped to prevent the flip-over rodent-blocking board from flipping inwards into the doorway.

[0009] Both the left and right columns have elongated mounting holes on their backs, which are then fixedly connected to the doorway wall or the side of the door frame using expansion bolts.

[0010] The flip-up rodent guard is filled with a lightweight reinforcing core material.

[0011] The surface of the flip-up rodent barrier is coated with an anti-corrosion and moisture-proof coating.

[0012] When the flip-up rodent barrier is flipped to a horizontal position, the difference in elevation between its upper surface and the ground is no more than 5mm.

[0013] The method for using a single-sided flip-up doorway rodent barrier as described above includes the following steps: S1, On-site layout and positioning, marking the installation positions of the two side columns to ensure they match the door opening and closing path; S2, fix the two columns symmetrically to the walls on both sides of the doorway with expansion bolts, and adjust the height so that the bottom of the rodent barrier is in contact with the ground when it is vertical; S3, the one-way flipping component is pre-installed on the lower part of the column through the flipping component fixing bolts, the coaxiality is adjusted to ensure smooth flipping, and the installation depth of the door leaf ball is adjusted to ensure reliable vertical positioning and moderate flipping resistance; S4, during daily use, the flip-up rodent barrier remains vertical under the action of the return spring and is positioned by the ball to prevent rodents from entering; S5: When personnel pass through or move equipment, gently push the rat guard outward to overcome the resistance of the ball bearings, and then flip the rat guard outward to lay flat, allowing unobstructed passage. S6. After passage is complete, the rodent barrier automatically returns to the vertical position under the action of the return spring, and the ball automatically engages in the positioning groove to complete the positioning. No additional manual operation is required throughout the process.

[0014] The main beneficial effects of this invention are as follows: It operates purely mechanically without power, ensuring high reliability. The entire process relies on mechanical structure for rotation and positioning, eliminating the need for motors, sensors, and power supply lines. This eliminates the problems of circuit failures and power outages. It is also moisture-proof, dustproof, and has a long service life, making it suitable for complex industrial environments.

[0015] The single-sided flip design balances rodent prevention and passage; it flips only to the side in the direction the door opens, with an inner limit block, ensuring that rodents cannot enter from the outside, while allowing passage from inside to outside by simply pushing it flat, making it unobstructed for moving equipment and emergency evacuation.

[0016] It is highly adaptable to installation and easy to modify; the whole is a modular structure, which can be fixed to both sides of the existing door opening with bolts, without the need for large-scale modification of the wall and door, and can directly replace the traditional fixed rodent barrier.

[0017] The reset buffer design provides a good user experience; the reset spring automatically resets, there is no extra noise during daily use, and the structure is stable after vertical positioning, making it less prone to displacement due to collisions. Attached Figure Description

Detailed Implementation

[0023] like Figures 1-5 A single-sided flip-up doorway rat barrier includes a left column 1, a right column 2, a flip-up rat barrier 3, a one-way flipping assembly 4, and a catch 6. The left column 1 and the right column 2 are symmetrically fixed to the walls on both sides of the doorway. The two ends of the flip-up rat barrier 3 are rotatably connected to the lower part of the two columns through the one-way flipping assembly 4. The one-way flipping assembly 4 restricts the flip-up rat barrier 3 to flip in one direction only along the opening direction of the door leaf 7 to a horizontal ground-facing state. The catch 6 is set on the inside of the column. When the flip-up rat barrier 3 is in the vertical rat-blocking state, the catch 6 is engaged in the positioning groove on the side of the flip-up rat barrier 3 to achieve vertical positioning of the flip-up rat barrier 3.

[0024] Preferably, the ball 6 uses an elastic clip to automatically position the rodent barrier in a vertical state, maintaining a stable rodent barrier state without the need for an additional power source.

[0025] In a preferred embodiment, the unidirectional flipping assembly 4 includes a flipping assembly housing 43, a flipping assembly inner shaft 41, and a return spring 42; the flipping assembly housing 43 is fixed to the inside of the column by flipping assembly fixing bolts 5.

[0026] In a preferred embodiment, the inner shaft 41 of the flip assembly is inserted inside the outer shell 43 of the flip assembly and is fixedly connected to the end of the flip rodent guard plate 3.

[0027] In a preferred embodiment, the return spring 42 is fitted onto the outside of the inner shaft 41 of the flip assembly, with one end connected to the outer shell 43 of the flip assembly and the other end connected to the inner shaft 41 of the flip assembly, providing a restoring force for the flipping rodent guard 3 to rotate to a vertical state.

[0028] Preferably, the inner shaft 41 of the flipping assembly is fixedly connected to the end of the rodent barrier as the flipping pivot, and the reset spring 42 is fitted on the outer side of the inner shaft. When the rodent barrier is stepped on during passage, the spring stores energy, and after the personnel pass through, it automatically drives the rodent barrier to rotate back to its original position, without the need for manual lifting.

[0029] In a preferred embodiment, the rodent-blocking post is L-shaped to prevent the flip-up rodent-blocking plate 3 from flipping inwards towards the doorway.

[0030] In a preferred embodiment, both the left column 1 and the right column 2 have elongated mounting holes on their backs, which are then fixedly connected to the doorway wall 8 or the side of the door frame using expansion bolts.

[0031] In a preferred embodiment, the flip-up rodent guard 3 is filled with a lightweight reinforcing core material.

[0032] Preferably, the flip-up rodent barrier 3 adopts a galvanized steel composite structure, which has moderate weight and strong impact resistance.

[0033] In a preferred embodiment, the surface of the flip-up rodent barrier 3 is provided with an anti-corrosion and moisture-proof coating.

[0034] Preferably, the surface is treated with anti-corrosion and moisture-proof measures to make it suitable for humid environments such as water conservancy projects and underground spaces.

[0035] In a preferred embodiment, when the flip-up rodent shield 3 is flipped to a horizontal position, the difference in elevation between its upper surface and the ground is no more than 5mm.

[0036] Preferably, when flipped to a horizontal position, the board surface is basically flush with the ground, with no obvious height difference, allowing for unobstructed passage.

[0037] Example 1, The single-sided flip-up doorway rodent barrier is designed for doorways that require both rodent protection and emergency passage. It is especially suitable for places equipped with fire doors, such as water conservancy ancillary rooms and power distribution rooms. The whole structure adopts a pure mechanical modular structure, which can achieve single-sided flip-up passage and vertical positioning rodent blocking without external power supply.

[0038] The core of this rodent barrier consists of five main parts: left column 1, right column 2, flip-up rodent barrier 3, one-way flip-up component 4, and ball bearing 6. Together with the flip-up component fixing bolt 5, it achieves complete functionality.

[0039] As shown in Figures 2 and 4, the one-way flip assembly 4 is the core component for achieving flipping and resetting, and is fixed to the inside of the column by the flip assembly fixing bolts 5. The one-way flip assembly 4 includes a flip assembly housing 43, a flip assembly inner shaft 41, and a reset spring 42; the flip assembly inner shaft 41 is installed inside the flip assembly housing 43, and its outer end is fixedly connected to the end of the flipping rodent guard plate 3, so that the flipping rodent guard plate 3 can rotate around the flip assembly inner shaft 41; the reset spring 42 is fitted on the outside of the flip assembly inner shaft 41, one end is engaged in the positioning groove of the flip assembly housing 43, and the other end is synchronously connected to the flip assembly inner shaft 41, providing a restoring force for the flipping rodent guard plate 3 to rotate back to the vertical state.

[0040] Referring to Figure 3, Figure 5 As shown, the catch ball 6 is embedded at the corresponding height position on the inner side of the column. When the flipped rat barrier 3 is in a vertical state, the steel ball of the catch ball 6 is locked into the corresponding positioning groove on the side of the column 1 and 2 under the action of the internal spring, realizing the vertical positioning of the rat barrier and preventing the rat barrier from being accidentally overturned by external force. When people push the flipped rat barrier 3 from inside to outside, the pushing force is greater than the locking force of the catch ball, the steel ball retracts and exits the groove, and the flipped rat barrier 3 can be flipped out smoothly and finally laid flat on the ground to form an unobstructed passage surface. There is no need to remove the rat barrier, and it can be passed quickly in case of emergency evacuation.

[0041] Both the left-side post 1 and the right-side post 2 are made of galvanized steel sheet bent into an L-shape, with vertical elongated mounting holes on the back. They can be directly fixed to the doorway wall 8 on both sides of the doorway or the side of the existing door frame using expansion bolts. The position can be slightly adjusted up and down during installation to adapt to doorways of different sizes. The flip-up rodent barrier 3 adopts a double-layer galvanized steel sheet composite structure with a honeycomb reinforcing core inside. The overall height is 550mm, which meets the rodent barrier height requirements and has sufficient structural strength to prevent deformation.

[0042] Example 2, In the preferred embodiment, the rodent-blocking method of the single-sided flip-up doorway rodent barrier as described above includes the following steps: S1, On-site layout and positioning, marking the installation positions of the two side columns to ensure compatibility with the opening and closing path of door leaf 7; S2, fix the two columns symmetrically to the walls on both sides of the doorway with expansion bolts, and adjust the height so that the bottom of the rodent barrier is in contact with the ground when it is vertical; S3, pre-install the one-way flipping component 4 on the lower part of the column through the flipping component fixing bolt 5, adjust the coaxiality to ensure smooth flipping, and at the same time adjust the installation depth of the door leaf 7 and the ball 6 to ensure reliable vertical positioning and moderate flipping resistance; S4, during daily use, the flip-up rodent barrier 3 remains vertical under the action of the return spring 42 and is positioned by the ball 6 to prevent rodents from entering; S5, when personnel pass through or transport equipment, gently push the rat guard plate 3 outward to overcome the resistance of the ball 6 and then flip the rat guard plate outward to lay it flat, so that they can pass through without obstruction; S6. After passage is completed, the rodent barrier automatically returns to the vertical position under the action of the return spring 42, and the ball 6 automatically engages in the positioning groove to complete the positioning. No additional manual operation is required throughout the process.

[0043] The above method, through a structural design of pure mechanical unidirectional flipping and ball-positioning, achieves stable rodent blocking and unobstructed passage of the rodent barrier without relying on electricity. It is perfectly suited to the usage needs of places such as water conservancy ancillary rooms and power distribution rooms, effectively solving the passage pain points of traditional rodent barriers and the reliability problems of electric rodent barriers, and has significant practical value and promotion prospects.

[0044] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The embodiments and features described in these embodiments can be arbitrarily combined without conflict. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
