Description

Technical Field

[0001] The present invention relates to the technical field of barrier nets, in particular to a barrier net for preventing small primates from climbing over. Background Art

[0002] Effectively restricting the range of small primates is crucial in animal management and research settings. However, current traditional barrier net technology has many limitations.

[0003] From a structural design perspective, traditional small primate barrier nets are mostly simple, static, fixed structures. Their surfaces are typically made of common materials, and the mesh size and cable strength are poorly designed. Small primates are agile and adept climbers. They use their flexible bodies and sharp claws to easily locate weak points in the net, such as larger mesh holes or cable connections. They can break through the barrier by climbing, pulling, or even biting through the cables, making such crossings extremely risky. This not only risks the animals escaping, posing a potential safety threat to nearby personnel and the environment, but also disrupts the normal order of animal management and research.

[0004] In terms of flexibility and adaptability, different species of small primates have significantly different behavioral habits and activity patterns. Furthermore, the need for barriers varies under different time and environmental conditions. However, traditional barrier nets have fixed functions and are difficult to adjust according to actual conditions. For example, during the breeding season, small primates are more active, their emotions are relatively unstable, and the risk of escape increases. Traditional barrier nets cannot meet the enhanced barrier requirements during this special period. Therefore, in response to the above-mentioned shortcomings, the present invention aims to address these problems and provide a barrier net that prevents small primates from climbing over.

The two limit card plates 14 are rotatably connected to the limit adjustment plate 15. The limit adjustment plate 15 is fixedly connected to the adjustment plate worm gear 17 through a rotating shaft. The outer surfaces of the side column 4 and the middle column 10 are provided with knobs 6. The knob 6 is fixedly connected to the knob worm gear 20 through a rotating shaft. The interiors of the side column 4 and the middle column 10 are both hollow structures. The interiors of the side column 4 and the middle column 10 are fixedly connected to worm brackets 19. The worm bracket 19 is rotatably connected to a worm 18. The two ends of the worm 18 are respectively meshed with the knob worm gear 20 and the adjustment plate worm gear 17. The outer surface of the middle column 10 is fixedly connected to a counter 9. The counter 9 is electrically connected to a proximity switch 21. The proximity switch 21 is fixedly connected to the side surface of the middle column 10.

[0031] A proximity switch 21 is located at the lower turning point of the annular guide groove 12, with its tip positioned at the bottom of the position-limiting plate 14. Both position-limiting plates 14 have slots on their outer surfaces, with two sets of slots located on the left and right sides of each plate. A stabilizing rod 22 is slidably connected to the outer arcuate edge of the position-limiting plate 14. The stabilizing rod 22 is slidably connected to the arcuate edge of the position-limiting adjustment plate 15, and the stabilizing rod 22 engages the left and right slots of the position-limiting plate 14. The annular guide groove 12 has a T-shaped cross-section, and a fixed pulley 23 is located within the annular guide groove 12.

[0032] The front and rear surfaces of the side columns 4 and the middle column 10 are fixedly connected with baffles 5, and the upper end surfaces of the front and rear groups of baffles 5 are connected to guide plates 7 through brackets. The inner side of the side column 4 is fixedly connected with a protective net 2, the other end of the protective net 2 is fixedly connected to the middle column 10, and the lower end of the protective net 2 is fixedly connected to a ground fixing pin 3. The mesh surface of the movable net 8 is slidably connected to the outer surfaces of the two support rods 11, and the base 1 is provided with multiple groups, and the end surface of the middle column 10 is fixedly connected to the base 1.

The outer surface of the baffle 5 is provided with a mounting hole for the knob 6, and the outer surface of the baffle 5 is provided with a mounting groove for the counter 9.

[0033] Working principle: When a small primate climbs the movable net, the net surface is forced to move downward, thereby driving the hook 13, the stabilizing rod 22 and the fixed pulley 23 to slide in the annular guide groove 12.

[0034] All equally spaced and active stabilizing rods 22 move with the movable net 8, sequentially passing the outer arc edge of the position-limiting plate 14. By rotating the knob 6 counterclockwise, the worm 18 drives the worm gear 17 of the adjustment plate, causing the position-limiting adjustment plate 15 to rotate to the left, exposing the right-side slot. At this point, when the stabilizing rods 22 are moved clockwise, they engage in the right-side slot, preventing the movable net 8 from moving further upward. However, when moving in the opposite direction, the stabilizing rods 22 can slide out along the outer arc edge of the position-limiting plate 14, achieving single-direction reciprocating rotation. Similarly, when the left-side slot of the position-limiting plate 14 is exposed, the stabilizing rods 22 engage in the left-side slot when they are moved counterclockwise.

[0035] When the knob 6 is adjusted so that the arc edge of the limit adjustment plate 15 is simultaneously released from the two slots, the left and right slots are exposed at the same time. When the stabilizing rod 22 is engaged with the corresponding slot, the arc surface at this rotation point is destroyed, so that the stabilizing rod 22 cannot slide smoothly, thereby achieving a completely locked state of the movable net 8.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
