Description

Technical Field

[0001] This utility model belongs to the field of animal husbandry technology, and specifically relates to a fence structure for sheep farming. Background Technology

[0002] Animal husbandry, as an important component of agriculture, primarily involves raising livestock and poultry through grazing, penning, or a combination of both. Sheep farming, due to its scale and economic value, occupies a crucial position within the animal husbandry system. In sheep farming, to achieve orderly management of the flock and prevent them from wandering off or being attacked by predators, fencing structures have become an indispensable infrastructure for sheep farms. However, currently available sheep farming fencing structures have revealed many limitations in practical use, particularly in height adjustment and assembly, making it difficult to meet the needs of different farming scenarios (such as lamb rearing, adult sheep rearing, etc.). To address the needs of sheep farming and different site layouts, targeted improvements have been made in related technical fields. For example, Chinese patent CN220587160U discloses a fence structure for sheep farming. This structure uses components such as a support base, reinforcing plate, pull-out railing, first load-bearing rod, and second load-bearing rod. By using a second fixing bolt passing through a third threaded hole and screwing into a fourth threaded hole, the height between the pull-out railing and the fence frame can be adjusted. This solves the problem of fixed height in traditional fences to a certain extent and provides a new approach to fence use in sheep farming.

[0003] However, the fence structure disclosed in the aforementioned patent still has significant defects and shortcomings in practical applications, making it difficult to fully meet the needs of efficient and flexible use in sheep farming scenarios: Firstly, the overall structural design is relatively simple, and the assembly of multiple fence units relies excessively on screws for fixing. This prevents the assembly process from being flexible and quick to assemble according to the specific needs of the actual farming site's size and shape, greatly reducing the efficiency of fence construction. Secondly, the screw connection method is highly dependent on disassembly and assembly tools, requiring specialized tools for each disassembly and assembly, making the operation cumbersome. Furthermore, during long-term outdoor use, dust, dirt, and other impurities easily accumulate in the thread gaps, easily leading to thread sticking and locking, further increasing the difficulty of disassembly and assembly, and complicating fence maintenance, adjustment, and other aspects. The existing structure suffers from several drawbacks: firstly, it is inconvenient to use; secondly, it lacks angle adjustment capabilities. When there are corners, irregular boundaries, or when the fence layout angle needs to be adjusted according to the breeding plan, the existing structure cannot achieve flexible angle combination installation. It can only be adapted by cutting or additional welding, which not only damages the integrity of the fence structure but also increases construction costs and operational complexity, severely limiting its applicability in diverse breeding site layouts. It is evident that the deficiencies of the existing sheep breeding fence structure in terms of assembly flexibility, disassembly convenience, and angle adaptability have become important factors restricting the efficient construction and management of sheep breeding sites. Therefore, further improving the design of the existing sheep breeding fence structure to solve the above-mentioned technical problems has important practical significance and application value.

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a fence structure for sheep farming to solve the problems raised in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fence structure for sheep farming includes a base frame, with hinge slots on both sides of the base frame. A rotating shaft is rotatably connected inside the hinge slot, and a snap-fit ​​mechanism is rotatably connected to the outer surface of the rotating shaft. A telescopic fence is installed on the outer side of the rotating shaft through the snap-fit ​​mechanism.

[0007] The locking mechanism includes a side frame, which is fixedly installed on the outside of the rotating shaft. Limiting card groups are fixedly installed at both the upper and lower ends of the side frame. An insert plate is inserted inside the side frame. The limiting card groups and the insert plate are interlocked with each other. The insert plate is fixedly installed on both sides of the telescopic fence.

[0008] As a preferred technical solution, the limiting card assembly includes a sliding groove and a card slot. The sliding groove is opened at the upper and lower ends of the side frame. A limiting spring is fixedly connected inside the sliding groove. A movable block is fixedly installed at the outer end of the limiting spring. The movable block is slidably connected inside the sliding groove. A side shaft is fixedly connected to the outer side of the movable block. A limiting card plate is fixedly installed through the side frame at the end of the side shaft. The card slot is opened at the top and bottom of the insertion plate. A card block is fixedly connected to the inner side of the limiting card plate. The card block is inserted into the inner side of the card slot.

[0009] As a preferred technical solution, an elliptical guide plate is rotatably connected to the front of the side frame, and a disassembly guide arm is fixedly installed on the front of the movable block. The elliptical guide plate and the disassembly guide arm are connected by a transmission.

[0010] As a preferred technical solution, a bridge-type handrail is fixedly connected to the front of the elliptical guide plate, and an installation guide slope is provided on the outer side of the card block.

[0011] As a preferred technical solution, the telescopic fence includes a frame, which is fixedly installed on the inner side of two insert plates. Fence sleeves are fixedly installed in a linear arrangement at equal intervals inside the frame. Extension fence tubes are slidably connected inside each fence sleeve. A top plate is fixedly installed on the top of each extension fence tube, and a limit component is fixedly installed in the middle of the back of the top plate.

[0012] As a preferred technical solution, the limiting component includes a fixed arm and a vertical plate. The fixed arm is fixedly installed on the middle of the back of the top plate, and the vertical plate is fixedly installed on the middle of the back of the frame. The vertical plate has locking holes arranged linearly at equal intervals in the middle. The lower end of the fixed arm is threadedly connected to a limiting screw. The end of the limiting screw is inserted into the locking hole. The limiting screw is a hand-tightening screw.

[0013] As a preferred technical solution, both ends of the back of the top plate are fixedly installed on the baffle, the baffle is located in the gap between each fence sleeve, the bottom of the frame is fixedly installed with an installation plate, and the four corners of the installation plate are provided with installation holes, which are countersunk holes.

[0014] In summary, the present invention has the following main advantages:

[0015] First, during the application of this technical solution, by setting up a snap-fit ​​mechanism and a rotating shaft and hinge groove structure, the base frame can be fixed and the rotating shaft adjusted first during use. Then, the snap-fit ​​mechanism can be used to quickly assemble the telescopic fence with the base frame. The assembly does not require screws or special tools. At the same time, pushing the telescopic fence can drive the rotating shaft to rotate and adjust the angle without cutting or welding the fence. This achieves the effect of improving assembly efficiency and enhancing the flexibility of angle adjustment. It solves the problems of low efficiency and poor flexibility caused by the reliance on screws in the existing fence assembly, as well as the need to damage the structure at corners to adjust the angle.

[0016] Secondly, during the application of this technical solution, by setting up a telescopic fence, a hand-tightened limiting screw, and a stop, the height can be adjusted by pushing the top plate to drive the extension fence tube to slide, and then fixed by the hand-tightened screw. No special tools are required. The stop can also cover the gaps in the fence to prevent cattle and sheep from squeezing out. When disassembling, rotating the elliptical guide plate can release the locking, and the return spring ensures the reliability of subsequent assembly. Thus, it achieves the effects of convenient height adjustment, enhanced fence restraint effect, and reduced disassembly and assembly difficulty. It solves the problems of existing technologies where fence height adjustment depends on special tools, is prone to thread locking, and is inconvenient to disassemble and assemble, and gaps can easily cause cattle and sheep to escape.

[0023] Example

[0024] refer to Figures 1 to 5 The fence structure for sheep farming in this embodiment includes a base frame 1. Both sides of the base frame 1 are provided with hinge grooves 2. The interior of the hinge groove 2 is rotatably connected to a rotating shaft 3. The outer surface of the rotating shaft 3 is rotatably connected to a snap-fit ​​mechanism 4. A telescopic fence 5 is installed on the outside of the rotating shaft 3 through the snap-fit ​​mechanism 4.

[0025] The snap-fit ​​mechanism 4 includes a side frame 41, which is fixedly installed on the outside of the rotating shaft 3. Limiting clips 42 are fixedly installed at both the upper and lower ends of the side frame 41. Insert plates 43 are inserted inside the side frame 41, and the limiting clips 42 and insert plates 43 are interlocked. Insert plates 43 are fixedly installed on both sides of the telescopic fence 5. During application, the device first provides basic support for the overall structure through the base frame 1. When it is necessary to connect the telescopic fence 5 to the base frame 1, the rotating shaft 3 can be placed in the hinge slots 2 on both sides of the base frame 1 using the cooperation of the rotating shaft 3 and the hinge slots 2. At this time, the rotating shaft 3 can rotate flexibly within the hinge slots 2. This design creates conditions for subsequent adjustment of the angle of the telescopic fence 5, avoiding the problem that the fixed angle of traditional fences is difficult to adapt to different sites. Subsequently, the snap-fit ​​mechanism 4 is used to connect the telescopic fence 5 to the rotating shaft 3. The side frame 41 of the telescopic fence 5 is fixed to the outside of the pivot 3, and the upper and lower ends of the side frame 41 are provided with limiting card groups 42. Simply insert the insert plates 43 on both sides of the telescopic fence 5 into the side frame 41, and the limiting card groups 42 will engage with the insert plates 43. No additional fasteners such as screws are needed, and no special tools are required. The telescopic fence 5 and the pivot 3 can be quickly assembled and fixed, which greatly improves the assembly efficiency and solves the problem of cumbersome and time-consuming assembly of traditional fences. In subsequent use, if it is necessary to adjust the layout angle of the telescopic fence 5, simply push the telescopic fence 5, which will drive the side frame 41 and the pivot 3 to rotate synchronously in the hinge groove 2 until the desired angle is adjusted. The whole process is simple to operate and does not require disassembly or modification of the fence structure, further enhancing the flexibility of fence use and meeting the needs of different breeding site layouts.

[0026] refer to Figure 5The limiting block 42 includes a slide groove 421 and a slot 422. The slide groove 421 is located at the upper and lower ends of the side frame 41. A limiting spring 423 is fixedly connected inside the slide groove 421. A movable block 424 is fixedly installed at the outer end of the limiting spring 423. The movable block 424 is slidably connected inside the slide groove 421. A side shaft 425 is fixedly connected to the outer side of the movable block 424. A limiting plate 426 is fixedly installed through the side frame 41 at the end of the side shaft 425. The slot 422 is located at the top and bottom of the insert plate 43. A locking block 427 is fixedly connected to the inner side of the limiting plate 426. The locking block 427 is inserted into the inner side of the slot 422. The front of the side frame 41 is rotatably connected. An elliptical guide plate 428 is provided, and a disassembly guide arm 429 is fixedly installed on the front of the movable block 424. The elliptical guide plate 428 and the disassembly guide arm 429 are connected by a transmission. A bridge-type handrail is fixedly connected to the front of the elliptical guide plate 428. An installation guide slope is provided on the outer side of the locking block 427. During the application of this device, when the telescopic fence 5 is connected to the side frame 41 through the locking mechanism 4, the limiting locking group 42 plays a key role. When the insert plates 43 on both sides of the telescopic fence 5 are inserted into the side frame 41, the insert plates 43 will first contact the installation guide slope on the outer side of the locking block 427. This slope can guide the insert plates 43 to advance smoothly, and at the same time push the locking block 427 to move outward. The limiting plate 426 moves synchronously, and the limiting plate 426 pulls the movable block 424 to slide in the slide groove 421 via the side shaft 425. During the sliding process, the movable block 424 compresses the limiting spring 423 in the slide groove 421, causing the limiting spring 423 to store elastic potential energy. As the insert plate 43 is continuously inserted, when the slots 422 at the top and bottom of the insert plate 43 are aligned with the locking block 427, the limiting spring 423 releases its elastic potential energy, pushing the movable block 424 to slide in the opposite direction. The movable block 424 drives the limiting plate 426 and the locking block 427 to reset via the side shaft 425. The locking block 427 inserts into the slot 422, completing the locking and fixing of the insert plate 43 and the side frame 41. The process requires no screws or special tools, greatly improving assembly convenience and solving the problem of cumbersome disassembly and assembly of traditional screw connections. If disassembly is required, the operator can hold the bridge-type handrail on the front of the elliptical guide plate 428 and rotate the elliptical guide plate 428. The elliptical guide plate 428 and the disassembly guide arm 429 on the front of the movable block 424 form a transmission engagement, driving the disassembly guide arm 429 to move. The disassembly guide arm 429 pulls the movable block 424 to compress the limit spring 423, causing the locking block 427 to disengage from the locking slot 422, and the insert plate 43 can be pulled out from the side frame 41. The disassembly operation is simple and labor-saving, further enhancing the flexibility of the fence and meeting the needs of subsequent maintenance or layout adjustment.

[0027] refer to Figures 1-4The telescopic fence 5 includes a frame 51, which is fixedly installed inside two insert plates 43. Fence sleeves 52 are fixedly installed inside the frame 51 in a linear arrangement at equal intervals. Extended fence tubes 53 are slidably connected inside each fence sleeve 52. A top plate 54 is fixedly installed on the top of each extended fence tube 53. A limit component 55 is fixedly installed in the middle of the back of the top plate 54. The limit component 55 includes a fixed arm 551 and upright plates 552. The fixed arm 551 is fixedly installed in the middle of the back of the top plate 54, and the upright plates 552 are fixedly installed in the middle of the back of the frame 51. The upright plates 552 are linearly arranged at equal intervals in the middle of their respective sections. The device has a locking hole 553, and the lower end of the fixed arm 551 is threadedly connected to a limiting screw 554. The end of the limiting screw 554 is inserted into the locking hole 553. The limiting screw 554 is a hand-tightening screw. Both ends of the back of the top plate 54 are fixedly installed on the baffle 555. The baffle 555 is located in the gap between each fence sleeve 52. The bottom of the frame 51 is fixedly installed with an mounting plate 556. Mounting holes 557 are provided at the four corners of the mounting plate 556. The mounting holes 557 are countersunk holes. During the application of this device, when adjusting the height of the telescopic fence 5 to adapt to different breeding needs, it can be done by operating the frame 51. In conjunction with the extension fence tube 53, when the fence needs to be raised, the top plate 54 is pushed upwards. The top plate 54 will cause the extension fence tube 53, which is fixed at the bottom, to slide along the inner wall of the fence sleeve 52 inside the frame 51 until the fence is adjusted to the required height. At this time, the height is fixed by means of the limiting component 55. Since the fixing arm 551 of the limiting component 55 is connected to the top plate 54 and the upright plate 552 is connected to the frame 51, it is only necessary to rotate the hand-tightening limiting screw 554 at the lower end of the fixing arm 551 and screw its end into the corresponding height locking hole 553 on the upright plate 552 to lock the relative position of the extension fence tube 53 and the fence sleeve 52. The entire height adjustment process requires no special tools and is easy to operate, solving the problem of traditional fences where the height is fixed or adjusted by tools. During fence use, the baffles 555 at both ends of the back of the top plate 54 can cover the gaps between the fence sleeves 52, preventing cattle and sheep from squeezing out of the gaps and ensuring the fence's restraining effect on the flock. At the same time, the mounting plate 556 at the bottom of the frame 51 can be connected to the ground or a fixed structure through the countersunk holes at its four corners, enhancing the overall installation stability of the telescopic fence 5, preventing the fence from shifting during use, further improving the reliability of the fence and meeting the needs of long-term breeding scenarios.

[0028] Operating Principle and Advantages: When using this device for sheep farming fencing, the first step is to assemble and install the fencing. The base frame 1 is fixed, utilizing its role as the foundation support for the entire fencing structure to provide a stable platform for subsequent component installation. The hinge slots 2 on both sides of the base frame 1 are specifically designed to provide installation positions for the rotating shaft 3. After the rotating shaft 3 is rotatably connected inside the hinge slot 2, its design allows free rotation within the slot, laying a crucial foundation for subsequent fencing angle adjustment. Next, the snap-fit ​​mechanism 4 is installed. By fixing the side frame 41 of the snap-fit ​​mechanism 4 to the outside of the rotating shaft 3, the side frame 41 and the rotating shaft 3 form a synchronous linkage structure. The limiting latches 42 fixed at the upper and lower ends of the side frame 41 are the core component for quick connection with the telescopic fence 5. The return spring fixed inside the slide groove 421 generates a continuous elastic thrust on the movable block 424 within the slide groove 421, pushing the movable block 424 to slide along the inner wall of the slide groove 421. The side... The shaft 425 moves synchronously with the movable block 424, which in turn drives the limiting plate 426 at the end of the side shaft 425 to move together. When the insert plates 43 fixed on both sides of the telescopic fence 5 are inserted into the side frame 41, they trigger the locking block 427 fixed on the inner side of the limiting plate 426 to accurately insert into the slots 422 opened at the top and bottom of the insert plate 43, completing the locking and fixing of the insert plate 43 and the side frame 41. Finally, the telescopic fence 5 and the base frame 1 are quickly assembled. In this process, by opening the installation guide slope on the outside of the locking block 427, the resistance when the insert plate 43 is inserted into the side frame 41 can be effectively reduced, and the insert plate 43 can be more smoothly inserted into the side frame 41, which significantly improves the ease of installation. Compared with the problem of poor assembly flexibility and low efficiency caused by screw fixing in the background technology, this technical solution achieves rapid assembly by setting the locking mechanism 4. No screw connection is required. The entire assembly process does not require special tools. The operation steps are simple and the assembly time is greatly shortened, thus effectively solving the problem of low assembly efficiency and poor flexibility of existing fences.

[0029] After the fence is assembled, the height of the telescopic fence 5 can be adjusted according to different actual breeding needs such as lamb breeding and adult sheep feeding. In this device, the frame 51 of the telescopic fence 5 is fixed inside the two insert plates 43. The frame 51 provides a space for the extension fence tube 53 through the fence sleeves 52 arranged linearly at equal intervals inside. The extension fence tube 53 can slide up and down along the inner wall of the fence sleeve 52. Through this sliding cooperation, the overall height of the fence can be directly changed. When the fence height needs to be adjusted, push the top plate 54. The top plate 54 will drive the extension fence tube 53 fixed at its bottom to slide synchronously along the inner wall of the fence sleeve 52 until the fence is adjusted to the required height.The adjusted height is then fixed using the limiting component 55. The fixing arm 551 of the limiting component 55 is fixed to the middle of the back of the top plate 54. The upright plate 552 fixed to the middle of the back of the frame 51 provides multiple height fixing positions through the equally spaced linearly arranged locking holes 553 in its middle. By rotating the limiting screw 554 threaded to the lower end of the fixing arm 551, which is a hand-tightening screw, no special tools are required. By screwing the end of the limiting screw 554 into the locking hole 553 of the corresponding height, the relative fixation of the extension fence tube 53 and the fence sleeve 52 can be achieved, thus completing the adjustment and locking of the fence height. At this time, the baffles 555 fixed at both ends of the back of the top plate 54 are located in the gaps between the fence sleeves 52. Since gaps will naturally form between the fence sleeves 52 after the frame 51 and the fence sleeves 52 are assembled, the baffles 555 can block these gaps to prevent cattle and sheep from squeezing out of the fence during the breeding process, ensuring the restraint effect of the fence on the flock, strengthening the restraint effect of the fence on the flock, and thus ensuring the safety and management order of the flock during the breeding process. This height adjustment design not only meets the fence height requirements of different breeding scenarios, but also avoids the problems mentioned in the background art by setting a hand-tightened limit screw 554. Because the screw connection requires specialized tools for disassembly and assembly, and long-term use can easily lead to thread lock-up, this device reduces the tool requirements for operators and makes fence height adjustment more convenient. When there are corners in the breeding site or the fence layout angle needs to be adjusted according to the breeding plan, the fence angle can be adjusted. This device utilizes the rotational connection between the base frame 1 and the rotating shaft 3. When the telescopic fence 5 is pushed, the telescopic fence 5 will drive the rotating shaft 3 to rotate along the inner wall of the hinge groove 2 of the base frame 1 through the snap-fit ​​mechanism 4. During the rotation of the rotating shaft 3, it will simultaneously drive the side frame 41 fixed to it and the telescopic fence 5 snapped to the side frame 41 to rotate together. The fence can be adjusted to the required angle without cutting or welding it. This allows for layout adaptation to different angles and meets the needs of irregular sites. In the background technology, existing fences lack angle adjustment function and need to be cut or welded at corners, which not only damages the integrity of the fence structure but also increases construction costs and operational complexity. However, this technical solution achieves flexible adjustment of the fence angle by setting a cooperative structure between the rotating shaft 3 and the hinge groove 2, without damaging the fence structure. This greatly improves the adaptability of the fence to diverse breeding sites and effectively solves the problem of difficult angle adjustment of existing fences.

[0030] When the fence needs to be disassembled for maintenance, layout adjustment, or reuse, disassembly and disassembly can be carried out. This device can achieve disassembly by operating the disassembly and assembly parts of the snap-fit ​​mechanism 4. Rotating the elliptical guide plate 428 on the front of the side frame 41, the bridge-type handrail fixed on the front of the elliptical guide plate 428 facilitates the operator's application of force, reducing the physical consumption of disassembly and assembly operations and improving operational convenience; the elliptical guide plate 428 and the disassembly and assembly guide arm 429 fixed on the front of the movable block 424 form a transmission connection, and the elliptical guide plate 428 rotates. When the guide arm 429 is pushed to move horizontally, the guide arm 429 in turn drives the movable block 424 to slide in the opposite direction along the inner wall of the slide groove 421 against the elastic force of the return spring. The movable block 424 drives the limiting plate 426 to move synchronously through the side shaft 425, so that the locking block 427 fixed inside the limiting plate 426 is disengaged from the slot 422 of the insert plate 43, and the locking and fixing of the insert plate 43 and the side frame 41 is released. At this time, the insert plate 43 can be pulled out from the side frame 41, and the telescopic fence 5 can be separated from the base frame 1. If further disassembly of the telescopic fence 5 is required, the end of the limit screw 554 can be disengaged from the locking hole 553 of the upright plate 552 by rotating the hand-tightened limit screw 554. Then, the top plate 54 can be pulled to retract the extension fence tube 53 into the fence sleeve 52, thus completing the disassembly and storage of the fence. In addition to providing thrust during assembly, the return spring of the locking mechanism 4 can also automatically reset the locking block 427 after disassembly, ensuring the reliability of the locking fixation during subsequent reassembly. The entire disassembly process does not require special tools and can be completed with simple operation, avoiding the problem of thread lock-up. This makes the maintenance, adjustment and reuse of the fence more convenient, thus completely solving the defects of the inconvenience of disassembly and assembly of existing fences. In addition, the mounting plate 556 fixed at the bottom of the frame 51 can be used to connect the frame 51 to the ground or other fixed structures through the countersunk holes opened at its four corners, further improving the overall installation stability of the telescopic fence 5, preventing the fence from shifting during use, and ensuring the stability of the entire fence structure during long-term use.
