Description

Technical Field

[0001] This utility model belongs to the field of fence technology, specifically a fence device to prevent pigs from escaping. Background Technology

[0002] Pigpen fencing is a facility built around a pigpen to restrict the pigs' movement and ensure their safety. It is typically made of sturdy materials such as metal, wood, or plastic, with sufficient height and strength to prevent pigs from jumping over or damaging it. In terms of application, pigpen fencing is widely used in various types of pig farms, from large-scale farms to small family-run operations. It is essential for rationally dividing the breeding areas, separating pigs at different growth stages and of different breeds, facilitating unified management and scientific feeding. At the same time, fencing also protects pigs from wild animals, reducing the risk of disease transmission, making it an indispensable infrastructure in the pig farming industry.

[0003] The existing pigpen fences cannot be adjusted in height according to the size of the pigs as they grow. As a result, the low fences are not effective in preventing the pigs from escaping once they grow up, making them ineffective. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a fence device to prevent pigs from escaping. It effectively solves the problem that the height of the existing pigpen fence cannot be adjusted according to the size of the pigs after they grow up, which makes it difficult for the low fence to effectively block the pigs as they grow up, and thus makes it easy for the pigs to escape.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fence device for preventing pig escape, comprising a base, rectangular sleeves fixedly installed at both ends of the top of the base, and several sleeves fixedly installed at equal intervals in the middle of the top of the base. Insert rods are fixedly installed at the inner bottom of two rectangular sleeves, and rectangular rods are fitted onto the surfaces of the two insert rods. Buffer springs are fixedly installed at the top of the two insert rods, and the tops of the two buffer springs are respectively fixedly connected to the inner tops of the two rectangular rods. Round rods are inserted into the interior of the several sleeves, and a support beam is fixedly installed between the tops of the several round rods and the two rectangular rods. A handle is provided on the upper part of one side of the middle sleeve, and transmission components are provided at both ends of the handle. The transmission components are connected to the two rectangular rods. When the handle is turned, power is output to the two rectangular rods through the transmission components, causing the two rectangular rods to move upwards and rise through the support beam, thereby increasing the interception height.

[0006] Preferably, the transmission assembly includes a shaft, which is fixedly installed in the middle of the throttle. Two bushings are rotatably installed on the surface of the throttle. The surfaces of the two bushings are fixedly connected to two sleeves through fixing heads. Gears are fixedly installed at both ends of the shaft. Ratchets are fixedly installed on the sides of the two gears that are far apart from each other. Positioning seats are rotatably installed on the sides of the two ratchet wheels that are far apart from each other. One end of the two positioning seats is fixedly connected to two rectangular sleeves respectively. A rack is meshed with one side of each of the two gears. Two racks are fixedly installed on one side of the two rectangular shafts respectively.

[0007] Preferably, each ratchet is provided with ratchet teeth on its upper part, and a bearing is fixedly installed at the upper end of each ratchet tooth. A rotating shaft is rotatably installed inside each of the two bearings. A positioning frame is rotatably installed at the ends of the two rotating shafts that are far apart from each other. One end of each positioning frame is fixedly connected to two rectangular sleeves. A pull ring is fixedly installed in the middle of one side of each of the two ratchet teeth.

[0008] Preferably, a transmission rod is rotatably mounted on the other side of each ratchet, a sliding sleeve is rotatably mounted on one end of each transmission rod, a sliding rod is inserted inside each sliding sleeve, one end of each sliding rod is fixedly connected to two rectangular sleeves, and a telescopic spring is sleeved on the surface of each sliding rod, with both ends of each telescopic spring fixedly connected to the sliding sleeve and the sliding rod, respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator drives the shaft to rotate inside the two bushings by turning the handle. When the shaft rotates, it drives the two ratchet wheels to rotate along the two positioning seats through the two gears. When the two gears rotate, they drive the two rectangular rods to move upward through the two racks. When the two rectangular rods move upward, they drive the two rectangular rods to move upward along the inside of the two rectangular sleeves through the support beam, and drive several round rods to move upward along the inside of the two sleeves. When the two ratchet wheels rotate, they will continuously push the two ratchet teeth due to the rotation in the direction of the two ratchet teeth. The two ratchet teeth will rotate upward along the two rotating shafts through the two bearings. When the two ratchet teeth rotate, they will push the sliding sleeve to slide along the surface of the sliding rod through the transmission rod, and at the same time squeeze the telescopic spring, so that the two ratchet wheels can only rotate in the direction of the two ratchet teeth. When rotating in the opposite direction of the ratchet teeth, they will be blocked, so as to lock the raising of the device and ensure its stability.

[0010] When the device needs to be lowered, the operator pushes the ratchet upwards via the pull ring, thereby releasing the limit on the two ratchet wheels. Then, under the gravity of several round rods, two rectangular rods, and the support beam, it moves downwards to reset and reduce its height. During the downward movement of the two rectangular rods, the two insert rods work together to compress the two buffer springs, and the elasticity of the two buffer springs provides cushioning to prevent damage to the device. This allows the height of the pigpen fence to be increased according to the size of the pigs as they grow, thus preventing the pigs from escaping, and it has a very good effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 6 The present invention includes a base 1, with rectangular sleeves 2 fixedly installed at both ends of the top of the base 1. Several sleeves 6 are fixedly installed at equal intervals in the middle of the top of the base 1. Insert rods 8 are fixedly installed at the bottom inner interior of each of the two rectangular sleeves 2. Rectangular rods 3 are fitted onto the surfaces of each of the two insert rods 8. Buffer springs 9 are fixedly installed at the top of each of the two insert rods 8. The tops of the two buffer springs 9 are respectively fixedly connected to the top inner interior of the two rectangular rods 3. Round rods 4 are inserted into the interior of each of the sleeves 6. A support beam 5 is fixedly installed between the round rods 4 and the tops of the two rectangular rods 3. A handle 7 is located on the upper part of one side of the sleeve 6 in the middle. Transmission components are located at both ends of the handle 7. The transmission components are connected to the two rectangular rods 3. When the handle 7 is turned, power is output to the two rectangular rods 3 through the transmission components, causing the two rectangular rods 3 to move upwards and rise through the support beam 5, thereby increasing the interception height.

[0022] In use, the operator drives the transmission component by turning the handle 7. When the transmission component is running, it moves the two rectangular rods 3 upward. As the two rectangular rods 3 move upward, they move along the inside of the two rectangular sleeves 2 through the support beam 5, and also move several round rods 4 upward along the inside of the two sleeves 6. The transmission component can also lock the device's height to ensure its stability. This allows the height of the pigpen fence to be increased according to the size of the pigs as they grow, thus preventing the pigs from escaping. It has a very good effect.

[0023] The transmission assembly includes a shaft 10, which is fixedly installed in the middle of a throttle 7. Two bushings 11 are rotatably mounted on the surface of the throttle 7. The surfaces of the two bushings 11 are fixedly connected to two sleeves 6 through fixing heads 12. Gears 13 are fixedly mounted at both ends of the shaft 10. Ratchets 15 are fixedly mounted on the side of the two gears 13 that are far apart from each other. Positioning seats 16 are rotatably mounted on the side of the two ratchet wheels 15 that are far apart from each other. One end of the two positioning seats 16 is fixedly connected to two rectangular sleeves 2 respectively. A rack 14 is meshed with one side of each of the two gears 13. The two racks 14 are fixedly mounted on one side of the two rectangular rods 3 respectively.

[0024] The operator drives the shaft 10 to rotate inside the two bushings 11 by turning the handle 7. When the shaft 10 rotates, it drives the two ratchet 15 to rotate along the two positioning seats 16 through the two gears 13. When the two gears 13 rotate, they drive the two rectangular rods 3 to move upward through the two racks 14. When the two rectangular rods 3 move upward, they drive the two rectangular rods 3 to move upward along the inside of the two rectangular sleeves 2 through the support beam 5, and drive several round rods 4 to move upward and rise along the inside of the two sleeves 6.

[0025] The upper part of each ratchet 15 is fitted with ratchet teeth 17, and the upper end of each ratchet tooth 17 is fixedly mounted with a bearing 19. The two bearings 19 are each rotatably mounted with a rotating shaft 18. The two rotating shafts 18 are each rotatably mounted with a positioning frame 20 at their opposite ends. One end of each positioning frame 20 is fixedly connected to two rectangular sleeves 2. A pull ring 25 is fixedly mounted in the middle of one side of each ratchet tooth 17. A transmission rod 21 is rotatably mounted on the other side of each ratchet tooth 17. A sliding sleeve 22 is rotatably mounted on one end of each transmission rod 21. A sliding rod 23 is inserted inside each sliding sleeve 22. One end of each sliding rod 23 is fixedly connected to two rectangular sleeves 2. A telescopic spring 24 is fitted on the surface of each sliding rod 23. Both ends of each telescopic spring 24 are fixedly connected to the sliding sleeve 22 and the sliding rod 23, respectively.

[0026] When the two ratchet wheels 15 rotate, they continuously push the two ratchet teeth 17 as they rotate in the same direction as the two ratchet teeth 17. This causes the two ratchet teeth 17 to rotate upwards along the two shafts 18 via the two bearings 19. When the two ratchet teeth 17 rotate, they push the sliding sleeve 22 to slide along the surface of the sliding rod 23 via the transmission rod 21, and simultaneously compress the telescopic spring 24. This ensures that the two ratchet wheels 15 can only rotate in the same direction as the two ratchet teeth 17. When they rotate in the opposite direction of the ratchet teeth 17, they will be blocked, thus locking the device to rise and ensuring its stability.

[0027] When the device needs to be lowered, the operator pushes the ratchet 17 upward through the pull ring 25, thereby releasing the limit on the two ratchet wheels 15. Then, under the gravity of several round rods 4, two rectangular rods 3 and support beam 5, it moves down to reset and reduce the height. During the downward movement of the two rectangular rods 3, the two insert rods 8 will cooperate to squeeze the two buffer springs 9. The elastic force of the two buffer springs 9 will buffer the movement and prevent the device from being damaged.
