Description

Technical Field

[0001] This utility model relates to the field of guardrail technology for pig farming, and more specifically, it relates to an adjustable guardrail for pig farming. Background Technology

[0002] In existing technologies, adjustable fences for pig farming are an important supporting facility for large-scale farms. They are mainly used for pen separation, passageway fencing, and security protection in pig farms, for zoned management and movement restriction of pigs at different growth stages. In actual breeding, pigs of different sizes, such as piglets, fattening pigs, and sows, have significantly different requirements for fence height. Piglets, being smaller, require lower fence heights for easy observation and management; fattening pigs, being of medium size, require moderate fence heights for effective enclosure; while sows and breeding pigs, being larger, require higher fence heights to ensure safety and protection. Furthermore, within the same breeding cycle, as pigs continue to grow and develop, their size increases, and the fence height needs to be adjusted accordingly to accommodate these changes. However, existing fence height adjustment methods typically use fixed structures, which cannot be flexibly and steplessly adjusted according to the actual size and specific needs of the pigs. This increases breeding costs and is inconvenient for daily management operations. The inability of fence height to flexibly match the actual size requirements of pigs affects the flexibility of breeding management.

[0003] Secondly, although some adjustable fences for pig farming on the market achieve stepless height adjustment through the cooperation of multiple components, these adjustable fences have defects such as simple adjustment mechanism design, insufficient fixing firmness, and lack of stability. After the fence is adjusted to the appropriate height and fixed, its fixing structure is easily affected by various external forces during actual use in the farm, such as the impact of pigs hitting the fence, the external force of pigs climbing and biting the fence, the operating force of the staff opening and closing the fence, and the water pressure impact of cleaning and disinfection operations. This can cause the originally adjusted and fixed fence fixing structure to shift and loosen, resulting in unexpected changes in the adjusted fence height. Problems such as the fence height being lowered and unable to effectively contain pigs, leading to pig escape, and the fence structure being unstable and posing safety hazards after the fixing is loose, not only seriously affect the use effect of the fence and the normal operation of farm management, but also require farm staff to check the fence condition and readjust and fix the height, increasing the workload of farm management and reducing the reliability and stability of the fence.

[0012] The present invention is further configured such that multiple anti-slip strips are provided on the outer side of the control sleeve, and multiple rubber strips are fixedly connected to the inner side of the action plate.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an adjustable guardrail for pig farming, which has the following beneficial effects: 1. By rotating a control sleeve with an action groove on the outside of the active sleeve, and connecting a mating sleeve to the control sleeve via threads on the outside of the active sleeve, and sliding a mating plate with an inclined mating groove on the inside of the active sleeve, the mating plate connects to a moving block, which in turn connects to a mating spring and an action plate. An auxiliary sleeve with an auxiliary groove is movably positioned within the active sleeve, and the moving block connects to the auxiliary block and slides within the auxiliary groove. An adjusting rod is slidably positioned within the adjusting sleeve, with its top connected to a crossbar and a sliding rod. This design achieves stepless height adjustment of the guardrail. During adjustment, rotating the control sleeve causes the mating sleeve to slide via threads. The mating sleeve then moves the auxiliary sleeve, pushing the moving block. The moving block causes the mating plate to slide along the inclined mating groove and expand outwards. The mating spring resets, releasing the action plate from the sliding rod. Sliding the sliding rod then adjusts the guardrail to any desired height. Operators only need to rotate the control sleeve and slide the sliding rod to achieve stepless adjustment, allowing for precise adjustment of the guardrail to any suitable height according to the actual needs of pigs of different sizes. Compared to existing technologies that use fixed structures and cannot be flexibly adjusted, this design effectively achieves a flexible match between the fence height and the pig's body size, improving the flexibility of breeding management.

[0014] 2. A multi-layered stable locking mechanism is established by using a fastening sleeve in conjunction with the moving rod, moving frame, and moving groove to limit the rotation of the control sleeve. A mating plate constrains the movement within an inclined mating groove, while the moving block and auxiliary block engage in an auxiliary groove. The actuating plate clamps and fixes the sliding rod with rubber strips. The rotating plate and fastening sleeve are locked together via longitudinal and transverse plates, creating a multi-layered stable locking mechanism. After adjustment, the actuating plate clamps the sliding rod with rubber strips to form the first layer of locking. Then, rotating the rotating plate resets the fastening sleeve, pushing the moving rod into the moving groove to form the second layer of locking. The fastening sleeve, moving rod, moving frame, and moving groove further restrict the rotation of the control sleeve to form the third layer of locking. The constraint of the mating plate in the inclined mating groove, combined with the limiting of the moving block and auxiliary block in the auxiliary groove, forms the fourth layer of protection. This multi-layered locking mechanism effectively resists the impact of pig collisions, the external forces from pig climbing and biting, the operational forces from operators switching on and off, and the water pressure impact from cleaning and disinfection. Compared with the shortcomings of existing technologies, such as simple adjustment mechanisms and insufficient fixing firmness, this design effectively prevents the fixing structure from shifting and loosening, avoids problems such as pigs escaping due to reduced fence height, and safety hazards caused by loose fence fixing, and improves the reliability and stability of fence use.

[0020] Please see Figures 1-5An adjustable guardrail for pig farming includes a support frame 1. An active sleeve 2 is fixedly mounted on the top and bottom of the support frame 1. A control sleeve 3 is rotatably mounted on the outer side of the active sleeve 2. A matching block 4 is fixedly mounted on one side of the active sleeve 2. A mating sleeve 5 is mounted on the outer side of the active sleeve 2. The outer wall of the mating sleeve 5 is movably connected to the inner wall of the control sleeve 3 via threads. A rotating plate 6 is rotatably mounted on the outer side of the active sleeve 2. A rotating groove 7 is formed on the rotating plate 6. A linkage block 8 is fixedly mounted on one side of the rotating plate 6. A linkage spring 9 connects the linkage block 8 and the matching block 4. A mating groove 10 is inclinedly formed on the inner side of the active sleeve 2. Multiple movement grooves 11 are formed on one side of the control sleeve 3. Multiple movement frames 12 are fixedly mounted on the outer side of the active sleeve 2. A lateral rotating rod 13 is provided, one end of which is inserted into a moving groove 11. A fastening sleeve 14 is provided on the outside of the active sleeve 2. A longitudinal plate 15 is connected to one side of the fastening sleeve 14. A transverse plate 16 is fixedly provided on one side of the longitudinal plate 15. Three transverse plates 16 are fixedly provided on one side of the longitudinal plate 15. A mating plate 17 is slidably provided in the mating groove 10. A moving block 18 is fixedly connected to one side of the mating plate 17. A mating spring 19 is connected to one side of the moving block 18. An actuating plate 20 is connected to the other end of the mating spring 19. An auxiliary sleeve 21 is movably provided in the active sleeve 2. An auxiliary groove 22 is opened on one side of the auxiliary sleeve 21. An auxiliary block 23 is connected to one side of the moving block 18. The auxiliary block 23 is slidably located in the auxiliary groove 22.

[0021] An adjusting sleeve 24 is fixedly provided on the inner side of the bracket 1. An adjusting rod 25 is slidably provided in the adjusting sleeve 24. A crossbar 26 is fixedly connected to the top of the adjusting rod 25. A sliding rod 27 is fixedly connected to the top of the crossbar 26. The sliding rod 27 slides through the main body sleeve.

[0022] In this embodiment, when the guardrail height needs to be adjusted, the rotating plate 6 is first rotated forward. Then, the rotating plate 6 drives the linkage block 8 on one side to rotate forward. The linkage block 8 then drives the linkage rod 36 on one side to rotate forward along the linkage hole 37. The linkage block 8 and the matching block 4 cooperate to compress the linkage spring 9. At the same time, the rotating plate 6 drives the rotating groove 7 and the thrust bearing 31 on one side to rotate forward. When the linkage spring 9 is compressed to its limit, the rotating groove 7 rotates to the position corresponding to the transverse plate 16. Then, the fastening sleeve 14 is pushed, so that the fastening sleeve 14 drives the inner sliding block 33 to slide along the sliding groove 32. The fastening sleeve 14 drives the longitudinal plate 15 and the transverse plate 16 on one side to gradually slide into the rotating groove 7. At the same time, the fastening sleeve 14 and the thrust bearing 31 cooperate to reset the spring 3. When the return spring 30 is compressed to its limit, the transverse plate 16 closest to the retaining sleeve 14 slides through the rotary groove 7 and slides to the other side of the rotary plate 6. At this time, the rotary plate 6 is released, and then the linkage spring 9 resets and pushes the linkage block 8, causing the linkage block 8 to drive one side of the linkage rod 36 to rotate in the opposite direction along the linkage hole 37 to reset. The linkage block 8 will also drive the rotary groove 7 and the thrust bearing 31 to rotate in the opposite direction to reset through the rotary plate 6, so that the rotary groove 7 rotates to a position that does not correspond to the longitudinal plate 15 and the transverse plate 16. At this time, the rotary plate 6 stops rotating, and the longitudinal plate 15, together with the transverse plate 16 closest to the retaining sleeve 14, limits the retaining sleeve 14 to one side of the rotary plate 6, so that the retaining sleeve 14 no longer limits one end of the moving rod 13. Then, rotating the control sleeve 3 forward causes the multiple moving grooves 11 on one side to rotate. The inner wall of each moving groove 11 then presses against one end of the moving rod 13. Due to the rounded corners of the inner wall of the moving groove 11 and the end of the moving rod 13, and the rotating connection between the moving rod 13 and the moving frame 12, the moving groove 11 extrudes one end of the moving rod 13, causing it to rotate within the moving frame 12 and the other end to rotate inward. Simultaneously, because the inner wall of the control sleeve 3 and the outer wall of the mating sleeve 5 are movably connected by threads, and because the cooperating block 35 and the cooperating groove 34 limit the rotation of the mating sleeve 5, the mating sleeve 5 causes the inner cooperating block 35 to slide along the cooperating groove 34, and the cooperating block 35 causes the inner auxiliary sleeve 21 to... The auxiliary sleeve 21 slides, and then the auxiliary block 23 moves through the auxiliary groove 22. The auxiliary block 23 then moves one side of the moving block 18. The moving block 18 then moves the guide rod 28, the guide groove 29, the mating spring 19, and the actuating plate 20. The moving block 18 also moves the other side of the mating plate 17 along the inclined mating groove 10. At the same time, the mating plate 17 moves the moving block 18 outward, causing the moving block 18 to move one side of the auxiliary block 23 outward along the auxiliary groove 22. This increases the distance between the moving block 18 and the actuating plate 20, causing the mating spring 19 to gradually return to its original position. When the mating spring 19 is fully returned to its original position, the moving block 18 will move the guide groove 29, the guide rod 28, the mating spring 19, and the actuating plate 20 outward.This causes the actuating plate 20 to no longer clamp the outer wall of the sliding rod 27. Then, the same steps are repeated at another location with the same structure. The sliding rod 27 is then slid, causing it to move the adjusting rod 25 along the adjusting sleeve 24 via the crossbar 26, thus achieving stepless adjustment of the guardrail height.

[0023] Please see Figures 3-5 As a further implementation of the overall device: a guide rod 28 is fixedly connected to one side of the action plate 20, and a guide groove 29 is opened in the moving block 18, with one end of the guide rod 28 slidably inserted into the guide groove 29.

[0024] A return spring 30 is movably sleeved on the outer side of the active sleeve 2. One end of the return spring 30 is connected to the fastening sleeve 14. A thrust bearing 31 is detachably installed on one side of the rotating plate 6. The other end of the return spring 30 is connected to the thrust bearing 31.

[0025] The active sleeve 2 has a sliding groove 32 on its outer side, and the fastening sleeve 14 has a sliding block 33 fixedly installed on its inner side. The sliding block 33 slides in the sliding groove 32.

[0026] The active sleeve 2 has a cooperating groove 34 on its side wall, and a cooperating block 35 is slidably disposed in the cooperating groove 34. The inner wall of the mating sleeve 5 is fixedly connected to the outer wall of the auxiliary sleeve 21 through the cooperating block 35.

[0027] A linkage rod 36 is connected to one side of the linkage block 8, and a linkage spring 9 is movably sleeved on the outside of the linkage rod 36. A linkage hole 37 is opened in the matching block 4, and one end of the linkage rod 36 slides into the linkage hole 37.

[0028] Multiple anti-slip strips 38 are provided on the outer side of the control sleeve 3, and multiple rubber strips 39 are fixedly connected to the inner side of the action plate 20.

[0029] More specifically, after the guardrail height is adjusted appropriately, the control sleeve 3 is first rotated in the reverse direction, causing the multiple moving slots 11 on one side to rotate in the reverse direction. Simultaneously, due to the threaded fit between the inner wall of the control sleeve 3 and the outer wall of the mating sleeve 5, the mating sleeve 5 causes the cooperating block 35 to slide in the reverse direction along the cooperating slot 34. At the same time, the cooperating block 35 causes the inner auxiliary sleeve 21 to slide in the reverse direction. The auxiliary sleeve 21 pushes one side of the moving block 18 to slide in the reverse direction, and the moving block 18 causes one side of the guide rod 28, guide slot 29, cooperating spring 19, and actuating plate 20 to slide in the reverse direction. Simultaneously, the moving block 18 causes the other side of the mating plate 17 to slide in the reverse direction along the mating slot 10, and the mating plate 17 causes one side of the moving block 18 to converge inwards. Then the moving block 18... The auxiliary block 23 on one side slides inward along the auxiliary groove 22, and the moving block 18 drives the guide groove 29, guide rod 28, cooperating spring 19, and actuating plate 20 to converge inward. Then, the inner wall of the actuating plate 20 gradually comes into contact with the outer wall of the slide rod 27, and the distance between the moving block 18 and the actuating plate 20 shortens, causing the guide rod 28 connected to one side of the actuating plate 20 to slide into the inner side of the guide groove 29. The actuating plate 20 and the moving block 18 cooperate to gradually press the cooperating spring 19. Then, the inner wall of the actuating plate 20 clamps the outer wall of the slide rod 27 through multiple rubber strips 39, thereby fixing the position of the active sleeve 2. At this time, the control sleeve 3 just drives the moving groove 11 to rotate and reset completely. At this time, the moving groove 11 rotates to the position corresponding to the original moving rod 13. Then, the rotary plate 6 is rotated forward again, and the rotary plate 6 drives the linkage block 8 on one side to rotate forward again. Then, the linkage block 8 drives the linkage rod 36 on one side to rotate forward along the linkage hole 37. The linkage block 8 and the matching block 4 cooperate again to squeeze the linkage spring 9. At the same time, the rotary plate 6 drives the rotary groove 7 and the thrust bearing 31 to rotate forward again. When the rotary groove 7 rotates to the position corresponding to the transverse plate 16, the reset spring 30 resets and pushes the fastening sleeve 14. Then, the fastening sleeve 14 drives the inner sliding block 33 to slide and reset along the sliding groove 32. The fastening sleeve 14 also drives the longitudinal plate 15 on one side and the three transverse plates 16 to slide and reset. At the same time, due to the chamfer design at one end of the fastening sleeve 14 and the rounded corner design at the end of the moving rod 13, ... One end of the rear retaining sleeve 14 gradually pushes the corresponding end of the moving rod 13 outward. Then, the moving rod 13 rotates back in the moving frame 12, causing the other end of the moving rod 13 to re-engage into the original moving groove 11. At this time, the return spring 30 is fully reset, and the other two transverse plates 16 move back to their original sides of the rotating plate 6. Then, the rotating plate 6 is released, and the linkage spring 9 resets again, pushing the linkage block 8 to reverse reset. The linkage block 8 then drives one side of the linkage rod 36 to reverse reset along the linkage hole 37. At the same time, the linkage block 8 drives the rotating groove 7 and one side of the thrust bearing 31 to reverse reset again through the rotating plate 6, causing the rotating groove 7 to reverse reset to a position that does not correspond to the longitudinal plate 15 and the transverse plate 16.Then, the longitudinal plate 15, in conjunction with its two corresponding transverse plates 16, supports the fastening sleeve 14 to one side of the rotating plate 6. Combined with the sliding block 33 and sliding groove 32, the fastening sleeve 14 is limited, preventing it from moving. The fastening sleeve 14, together with the moving rod 13, moving frame 12, and moving groove 11, forms a rotation limit on the control sleeve 3, preventing accidental rotation. Then, the same steps are repeated on another identical structure to ensure the structural stability after the guardrail height adjustment, ensuring the stable use of the guardrail.

[0030] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the height of the guardrail, firstly, rotate the rotary plate 6 in the forward direction. Then, the rotary plate 6 will drive the linkage block 8 on one side to rotate in the forward direction. Then, the linkage block 8 will drive the linkage rod 36 on one side to rotate in the forward direction along the linkage hole 37. The linkage block 8 will cooperate with the matching block 4 to compress the linkage spring 9. At the same time, the rotary plate 6 will drive the rotary groove 7 and the thrust bearing 31 on one side to rotate in the forward direction. When the linkage spring 9 is compressed to its limit, the rotary groove 7 will rotate to the position corresponding to the transverse plate 16. Then, push the fastening sleeve 14, so that the fastening sleeve 14 drives the inner sliding block 33 to slide along the sliding groove 32. And the fastening sleeve 14 drives the longitudinal plate 15 and the transverse plate 16 on one side to gradually slide into the rotary groove 7. The retaining sleeve 14, in conjunction with the thrust bearing 31, compresses the return spring 30. When the return spring 30 is compressed to its limit, the transverse plate 16 closest to the retaining sleeve 14 slides through the rotary groove 7 and to the other side of the rotary plate 6. At this point, the rotary plate 6 is released, and the linkage spring 9 resets, pushing the linkage block 8. This causes the linkage block 8 to drive one side of the linkage rod 36 to rotate in the opposite direction along the linkage hole 37. The linkage block 8, through the rotary plate 6, drives the rotary groove 7 and the thrust bearing 31 to rotate in the opposite direction, thus causing the rotary groove 7 to rotate and reset to a position that does not correspond to the longitudinal plate 15 and the transverse plate 16. At this point, the rotary plate 6 stops rotating, and the longitudinal plate 15, in conjunction with the transverse plate 16 closest to the retaining sleeve 14, limits the retaining sleeve 14. The control sleeve 3 rotates forward, causing the locking sleeve 14 to no longer limit one end of the moving rod 13. The control sleeve 3 then rotates, causing multiple moving grooves 11 on one side to rotate. The inner wall of the moving groove 11 presses against one end of the moving rod 13. Due to the rounded corners of the inner wall of the moving groove 11 and the end of the moving rod 13, and the rotating connection between the moving rod 13 and the moving frame 12, the moving groove 11 extrudes one end of the moving rod 13, causing it to rotate within the moving frame 12 and the other end to rotate inward. Simultaneously, because the inner wall of the control sleeve 3 and the outer wall of the mating sleeve 5 are movably connected by threads, and because the cooperating block 35 and the cooperating groove 34 limit the rotation of the mating sleeve 5, the mating sleeve 5 will... The inner cooperating block 35 slides along the cooperating groove 34, and the cooperating block 35 drives the inner auxiliary sleeve 21 to slide. Then, the auxiliary sleeve 21 drives the auxiliary block 23 to move through the auxiliary groove 22. The auxiliary block 23 then drives the moving block 18 on one side to move. The moving block 18 then drives the guide rod 28, guide groove 29, mating spring 19, and actuating plate 20 to move. The moving block 18 also drives the mating plate 17 on the other side to slide along the inclined mating groove 10. At the same time, the mating plate 17 drives the moving block 18 to spread outward, so that the moving block 18 drives the auxiliary block 23 on one side to slide outward along the auxiliary groove 22, thus increasing the distance between the moving block 18 and the actuating plate 20. Then, the mating spring 19 gradually returns to its original position.After the spring 19 is fully reset, the moving block 18 will drive the guide groove 29, guide rod 28, spring 19, and actuating plate 20 to slide outward, so that the actuating plate 20 no longer clamps the outer wall of the slide rod 27. Then, the same steps are repeated for another identical structure. Then, slide the slide rod 27, so that the slide rod 27 drives the adjusting rod 25 to slide along the adjusting sleeve 24 through the crossbar 26, thereby realizing stepless adjustment of the guardrail height.

[0031] After the guardrail height is adjusted appropriately, firstly, the control sleeve 3 is rotated in the reverse direction, causing the multiple moving slots 11 on one side to rotate in the reverse direction. Simultaneously, due to the threaded fit between the inner wall of the control sleeve 3 and the outer wall of the mating sleeve 5, the mating sleeve 5 will cause the cooperating block 35 to slide in the reverse direction along the cooperating slot 34. At the same time, the cooperating block 35 will cause the inner auxiliary sleeve 21 to slide in the reverse direction. The auxiliary sleeve 21 will push one side of the moving block 18 to slide in the reverse direction, and the moving block 18 will cause one side of the guide rod 28, guide slot 29, cooperating spring 19, and actuating plate 20 to slide in the reverse direction. Simultaneously, the moving block 18 will cause the other side of the mating plate 17 to slide in the reverse direction along the mating slot 10, and the mating plate 17 will cause one side of the moving block 18 to converge inwards. Then, the moving block 18 will drive a... The side auxiliary block 23 slides inward along the auxiliary groove 22, and the moving block 18 drives the guide groove 29, guide rod 28, cooperating spring 19, and actuating plate 20 to converge inward. Then, the inner wall of the actuating plate 20 gradually comes into contact with the outer wall of the slide rod 27, and the distance between the moving block 18 and the actuating plate 20 shortens, causing the guide rod 28 connected to one side of the actuating plate 20 to slide into the inner side of the guide groove 29. The actuating plate 20 and the moving block 18 cooperate to gradually press the cooperating spring 19. Then, the inner wall of the actuating plate 20 clamps the outer wall of the slide rod 27 through multiple rubber strips 39, thereby fixing the position of the active sleeve 2. At this time, the control sleeve 3 just drives the moving groove 11 to rotate and reset completely. At this time, the moving groove 11 rotates to the position corresponding to the original moving rod 13, and then... The rotating plate 6 is rotated forward again, and then the rotating plate 6 drives the linkage block 8 on one side to rotate forward again. Then the linkage block 8 drives the linkage rod 36 on one side to rotate forward along the linkage hole 37. The linkage block 8 and the matching block 4 cooperate again to squeeze the linkage spring 9. At the same time, the rotating plate 6 drives the rotating groove 7 and the thrust bearing 31 to rotate forward again. When the rotating groove 7 rotates to the position corresponding to the transverse plate 16, the return spring 30 returns to its original position and pushes the fastening sleeve 14. Then the fastening sleeve 14 drives the inner sliding block 33 to slide and return to its original position along the sliding groove 32. The fastening sleeve 14 also drives the longitudinal plate 15 on one side and the three transverse plates 16 to slide and return to their original positions. At the same time, due to the chamfer design at one end of the fastening sleeve 14 and the rounded corner design at the end of the moving rod 13, then... One end of the fastening sleeve 14 gradually pushes the corresponding end of the moving rod 13 outward. Then, the moving rod 13 rotates back in the moving frame 12, causing the other end of the moving rod 13 to re-engage into the original moving groove 11. At this time, the return spring 30 is fully reset, and the other two transverse plates 16 have moved back to their original sides of the rotating plate 6. Then, the rotating plate 6 is released, and the linkage spring 9 resets again, pushing the linkage block 8 to reverse reset. The linkage block 8 then drives one side of the linkage rod 36 to reverse reset along the linkage hole 37. At the same time, the linkage block 8 drives the rotating groove 7 and one side of the thrust bearing 31 to reverse reset again through the rotating plate 6, causing the rotating groove 7 to reverse reset to a position that does not correspond to the longitudinal plate 15 and the transverse plate 16.Then, the longitudinal plate 15, in conjunction with its two corresponding transverse plates 16, supports the fastening sleeve 14 to one side of the rotating plate 6. Combined with the sliding block 33 and sliding groove 32, the fastening sleeve 14 is limited, preventing it from moving. The fastening sleeve 14, together with the moving rod 13, moving frame 12, and moving groove 11, forms a rotation limit on the control sleeve 3, preventing accidental rotation. Then, the same steps are repeated on another identical structure to ensure the structural stability after the guardrail height adjustment, ensuring the stable use of the guardrail.
