[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0028] like Figure 1 As shown, a boar restraint device with injury reduction function according to this application includes a fixation frame 1, a flexible fixation strap 2, a padding layer 3, an adjustment device 4, and a support column 5. The design of this boar restraint device aims to reduce the injury problem of boars during the restraint process.

[0029] The fixed frame 1 supports the entire restraint apparatus and provides structural stability. To ensure its strength and rigidity, the fixed frame 1 is typically made of metal alloy or high-strength plastic. The main function of the fixed frame 1 is to serve as the base of the entire device, to which all other components are connected via appropriate connection methods. For example, in practical applications, the fixed frame 1 can be a rectangular frame with a certain height to support the remaining components. The internal space of the frame is rationally designed to ensure sufficient space to accommodate and comfortably restrain the body shape of the breeding pig. Support columns 5, described later, are installed at the four corners of the fixed frame 1 to increase the ground clearance of the device and prevent an increased risk of potential damage to the pig's hooves and other parts due to rough ground.

[0030] Flexible restraint straps 2 are positioned on the restraint frame 1 and securely bind the boar to important physiological structures such as the neck and limbs. These straps are made of a soft synthetic material, offering good elasticity and durability. This material selection aims to evenly distribute the force across the skin surface while minimizing the potential for physical damage from localized pressure points. The flexible restraint straps 2 cover a large area of ​​the body contour and their tightness can be flexibly controlled via adjustment mechanisms located at the ends of the straps. Each strap has multiple sections of soft protective sheaths 10 embedded in its surface, which absorb shear stress generated during vigorous boar movements, preventing excessive stretching and tearing injuries at the restraint sites.

[0031] The padding layer 3 is disposed on the inner surface of the fixed frame 1. This padding layer 3 is composed of highly resilient polymer foam, and its thickness is determined according to the specific application scenario to provide a certain protective effect without affecting the overall size and specification requirements. The side of the padding layer 3 facing the object to be supported is constructed with a conforming curve, which can naturally deform with the shape of the pig's limbs to achieve a better support effect. This disperses the local pressure caused by the weight load, reduces the pig's psychological discomfort, helps maintain its relaxed state, and reduces the possibility of additional injuries caused by tension.

[0032] The adjustment device 4 is located at the joint between the ends of the flexible fixing belt 2. It is a complete system consisting of several locking parts that move and are fixed along the guide rail groove. It can flexibly adjust the binding firmness according to the differences in the size and scale of different varieties of individuals without causing abnormal compression. According to the actual situation, the user can easily and quickly achieve appropriate locking and loosening by manually operating the bolt-type quick-release switch, ensuring a safe and humane way to complete the operation procedure and achieve the goal.

[0033] Support columns 5 are placed at the four corners of the fixed frame 1. These components are designed to raise the overall equipment height, placing it above the horizontal floor level for operation, effectively isolating it from moisture, gravel, and sharp objects that could interfere with or damage the equipment. Specifically, tubular or block-shaped columns are used to achieve the intended purpose. Lightweight but appropriately hard metal materials are typically chosen to ensure stable placement while facilitating assembly, disassembly, maintenance, and repair.

[0034] Throughout the process, the boar restraint device of this application with damage reduction function solves the problem that under normal conditions, boars will cause abrasions and scratches on the body surface and even damage to deep soft tissues due to their large twisting and struggling behavior in resistance to restraint.

[0035] In one embodiment, reference Figure 1 and Figure 4 The present application discloses a restraining device for breeding pigs with injury reduction function, wherein the height of the fixing frame 1 is adjustable. To accommodate breeding pigs of different sizes and overcome the effects of uneven ground, the height of the fixing frame 1 can be adjusted according to specific needs. This adjustment is achieved by adjusting feet 6 installed at the bottom of the fixing frame 1. By changing the height of these adjusting feet 6, not only can the entire restraining device be ensured to be stable on the ground, but the overall structural height can also be flexibly adjusted, thereby providing a more suitable support environment for individual use and helping to reduce potential physical injury caused by accidents. More specifically, the adjusting feet 6 can be located at the bottom of the support column 5.

[0036] For example, the adjustable foot 6 is made of high-strength metal and is securely connected to the fixed frame 1 to ensure its stability. The adjustable foot 6 is designed with a threaded or hydraulic lifting mechanism, allowing operators to manually adjust it or quickly set it to the appropriate height using a special tool, depending on the actual situation. Specifically, the bottom of the fixed frame 1 has pre-drilled mounting holes to accommodate the adjustable foot 6, and the two are secured using anti-loosening screws or embedded connections, ensuring good performance even in applications requiring frequent adjustments or in rough environments.

[0037] Still referencing Figure 1 In one embodiment, the flexible restraint strap 2 of a boar restraint device with injury reduction function of this application is provided with an anti-slip pad 7 on its inner side. This anti-slip pad 7 effectively increases friction, preventing injury to the boar due to relative slippage of the restraint strap during restraint. This design cleverly combines the characteristics of the flexible restraint strap 2, further enhancing safety and comfort while ensuring restriction of the boar's movement. The anti-slip pad 7 is located on the inner surface area of ​​the flexible restraint strap 2 that directly contacts the boar, and its range is flexibly designed according to different boar sizes, providing a wide coverage area.

[0038] The anti-slip mat 7 is typically made of highly abrasion-resistant and soft materials, such as silicone or a high-elasticity fabric composite material, ensuring sufficient friction without increasing pressure or discomfort on the pig's skin. This anti-slip mat 7 is firmly attached to the flexible fixing strap 2 by adhesive or sewing, ensuring stability and long-term effectiveness throughout the entire maintenance period. Even with prolonged use, it maintains good grip performance, ensuring a durable and reliable anti-slip effect.

[0039] For example, a moderately thick anti-slip pad 7 can be laid on the inner layer of the flexible fixing band 2 and then glued and fixed using environmentally friendly high-strength adhesive. Alternatively, a cable compatible with the material of the flexible fixing band 2 can be used to tightly connect the two with dense pins. Regardless of the connection method chosen, a tight and stable bond between the two can be ensured, thereby achieving the ideal anti-slip effect.

[0040] In one embodiment, the padding layer 3 of a boar restraint device with damage reduction function of this application has varying thicknesses at different locations within the fixation frame 1. To better protect vulnerable areas of the boar, the padding layer 3 is relatively thicker at key stress points such as the head, neck, and abdomen, providing additional cushioning to reduce the risk of injury to these areas due to stress. This differentiated thickness treatment not only reflects attention to the animal's physiological characteristics but also demonstrates that the design process deeply considered how to mitigate the potential harm caused by concentrated pressure on livestock.

[0041] Specifically, a thicker padding layer 3 is installed near the head and abdomen of the fixed frame 1. This thick padding structure is significantly different from the thinner layer in ordinary locations, in order to meet the greater shock absorption requirements of these special parts. The thickness can effectively absorb and disperse the impact of external forces on these sensitive areas, avoiding tissue damage caused by localized pressure. This differentiated arrangement ensures an optimized configuration of overall safety and comfort.

[0042] For example, the required thickness can be achieved by using a highly elastic foam material as a base and then performing specific geometric deformation processing or layering techniques on it. For instance, during the manufacturing process, a template can be pre-set based on the body shape of the breeding pig, and grooves with sufficient height can be reserved in the head and abdomen areas to fill with thicker foam units. Then, the entire structure can be flattened and pressed into the final desired shape. Alternatively, two or more pieces of materials of different thicknesses can be combined and spliced ​​together, and accurately positioned and installed in place during the assembly stage of the fixed frame 1, so that the padding layer 3 can provide sufficient support in the corresponding positions without increasing the redundant volume in other areas.

[0043] In one embodiment, such as Figure 2 As shown, the adjustment device 4 of the boar restraint device with injury reduction function of this application also includes a tension sensor 8, which is connected to the control unit within the adjustment device 4. The tension sensor 8 is connected to the flexible restraint strap 2 and can sense and report the real-time tension state of the restraint strap to the control unit when the boar struggles. Based on this real-time data, the control system can respond promptly and dynamically fine-tune the tightness of the restraint strap through the adjustment device 4. This ensures that the restraint force remains moderate under various conditions, thereby achieving the necessary restraint function while avoiding the risk of injury caused by excessive pressure on the boar.

[0044] To achieve the above functions, a tension sensing module has been added to the structural design of the adjustment device 4. Specifically, the tension sensor 8 is installed near the joint of the fixing strap and integrated into a compact housing, compatible with the existing slide rails and buckles without hindering its operability. It is electrically connected to the control unit via a built-in signal line. When the sensor detects additional pulling on the fixing strap due to the animal's movements, it converts this information into an electrical signal and transmits it to the controller, triggering the micro-adjustment system to loosen or tighten the strap by an appropriate length to balance the change in external force, thereby achieving intelligent adjustment. In this way, even if the breeding pig suddenly struggles violently, it will not be injured or the device will malfunction.

[0045] In one embodiment, see specific reference. Figure 4The present application discloses a boar restraint device with injury reduction function, in which the support column 5 is equipped with an anti-slip pad 9 at its bottom. The anti-slip pad 9 significantly increases the friction between the support column 5 and the ground, thereby ensuring that the entire device remains stable and does not shift during use. The anti-slip pad 9 provides additional safety, especially when the boar struggles. This design effectively improves the stability and safety of the overall device, avoiding potential risks to operators and boars due to device slippage.

[0046] Specifically, the anti-slip pad 9 is located at the bottom end of the support column 5, and more specifically, it can be located at the bottom of the adjustable foot 6, and is effectively connected to the adjustable foot 6 by mechanical fixing. This anti-slip pad 9 is made of highly wear-resistant and tear-resistant material, providing excellent grip and reliable support even on rough or smooth surfaces. To ensure the durability and functionality of the anti-slip pad 7, materials with a high coefficient of friction, such as rubber or other high-performance synthetic materials, are preferred in material selection.

[0047] For example, the anti-slip pad 9 and the adjusting foot 6 are connected by nesting or adhesive bonding. For instance, the anti-slip pad 9 has a groove inside to accommodate the outer edge of the bottom of the adjusting foot 6, and then they are firmly joined together by strong adhesive or other fixing methods. This design ensures a tight fit between the two and facilitates future replacement or maintenance. At the same time, during installation, attention should be paid to the cleanliness and flatness of the anti-slip pad 7 surface to ensure maximum friction when in contact with the ground.

[0048] In one embodiment, such as Figure 1 As shown, the flexible fixing band 2 of the boar restraint device of this application, which has the function of reducing injury, is provided with multiple protective sleeves 10 on its surface. These protective sleeves 10 are not a continuous structure, but are divided into multiple independently movable segments. Each protective sleeve 10 is made of elastic material and is independently connected to the outer surface of the flexible fixing band 2. In this way, each protective sleeve 10 can be locally adjusted according to the amplitude and frequency of movement of different parts of the boar. When the boar struggles or moves, the protective sleeve 10 in a specific area will flexibly stretch or contract with the movement of that area. This independent segment design helps to prevent excessive traction caused by a single continuous protective sleeve 10, ensuring that the pressure of the protective sleeve 10 in contact with the skin remains uniform. Since each independent part corresponds to only a small area of ​​the body, it can better adapt to the slight morphological changes and twisting of that area, making the entire device more fitting and comfortable, and effectively reducing the risk of skin friction and pressure injury.

[0049] Specifically, the flexible fixing band 2 can be divided into several sections to accommodate the protective sleeves 10. Appropriate gaps are left between adjacent protective sleeve sections 10 to avoid interference, and they are indirectly connected as a single unit using flexible material. The end of each protective sleeve section 10 may be attached to the flexible fixing band 2 via Velcro or a similar mechanism, ensuring both secure coverage and allowing for relative sliding, enabling each part to freely adjust its position to adapt to the movement needs of the breeding pig.

[0050] In one embodiment, the fixing frame 1 of the boar restraint device of this application, which has a damage reduction function, has several protrusions 11 on its internal contact surface. More specifically, these protrusions 11 can be provided on the padding layer 3 and in areas on the inner side of the fixing frame 1 where the padding layer 3 is not provided. The main function of these protrusions 11 is to increase the friction between the fixing frame 1 and the boar's body surface. In this way, even if the boar attempts to move during restraint due to struggling or other reasons, it can be effectively prevented from sliding. In addition, the design of these protrusions 11 takes into account the characteristics of the boar's body surface, providing sufficient friction while avoiding direct pressure or excessive damage to the skin. To ensure safety, the fixing frame 1 has a robust overall structure and can be appropriately adjusted according to the actual body size and posture of the boar.

[0051] In practical applications, the protrusions 11 are evenly distributed on the internal contact surface of the fixed frame 1. From a material and structural perspective, these protrusions 11 are made of soft and elastic materials, such as silicone or TPU, ensuring a stable friction effect on the surface without causing unnecessary physical strain or discomfort due to excessive hardness. To achieve optimal performance, the protrusions 11 can be arranged in different shapes, such as circles, rhombuses, or stripes; at the same time, they maintain an appropriate spacing design. Furthermore, to avoid wear caused by prolonged contact, the material formulation and surface treatment process can be further optimized.

[0052] For example, in a specific technical solution, these protrusions 11 can be directly embedded into the padding layer 3 installed inside the fixed frame 1 through an in-mold molding process. The padding layer 3 itself is made of high-elasticity foam material, which not only enhances the overall structural stability, but also allows each protrusion 11 to fit properly with the changes in the body curve of the breeding pig, thereby achieving the above design intention more accurately and effectively.

[0053] In one embodiment, the outer surface of the pad 3 of a boar restraint device with damage reduction function is coated with an antibacterial material 12. This coating effectively inhibits bacterial growth, thereby ensuring the cleanliness and hygiene of the pad 3 during prolonged use. The pad 3 is located at the contact surface inside the fixing frame 1, in direct contact with the boar's body, providing cushioning and pressure relief during restraint. By applying the antibacterial material, not only are the health risks caused by bacterial proliferation reduced, but a safe and comfortable restraint environment for the boar is also ensured.

[0054] The coating is applied to the surface of bedding layer 3 using a special process and adheres tightly. The selected antibacterial material possesses excellent durability and stability, maintaining good performance even under frequent use and cleaning conditions. This material may include broad-spectrum antibacterial components such as silver ions to ensure effective killing of various common pathogens. The coating covers the entire external area of ​​bedding layer 3 without any gaps, ensuring that even under repeated friction or moisture, bedding layer 3 will not affect the health of the breeding pigs due to the growth of microorganisms inside.

[0055] For example, during the manufacturing stage, a liquid containing antibacterial agents can be evenly applied to the padding layer 3, which is made of highly elastic foam material, using spraying or dipping methods. Then, it is dried under appropriate temperature and humidity conditions to allow the antibacterial agents to fully penetrate and firmly adhere to the foam structure, thereby forming a strong and durable antibacterial protective layer. The padding layer 3, after this treatment, not only resists bacterial invasion but also retains its original soft, comfortable, and adaptable characteristics, effectively alleviating the stress felt by breeding pigs when restrained.

[0056] In one embodiment, the height of the support column 5 of the boar restraint device with injury reduction function is set to be greater than the width of the fixing frame 1. This design allows the fixing frame 1 to be placed more stably on the ground, avoiding potential injury to the boar due to shaking or movement. By reasonably matching the size of the fixing frame 1 and the length of the support column 5, the stability of the entire device is enhanced, while reducing the possibility of secondary injury to the boar due to accidental movement or tilting.

[0057] To improve the overall stability of the device, each support column 5 is placed at one of the four corners of the fixed frame 1, extending beyond the plane of the fixed frame 1 to effectively prevent the fixed frame 1 from tipping over. The support columns 5 are securely connected to the fixed frame 1, for example, through high-strength welding or by using fasteners such as bolts and flanges, ensuring that the entire restraint device remains stable even when the boars are moving vigorously. Furthermore, this design allows for a certain amount of space beneath the fixed frame 1, preventing direct contact between the pigs and the damp, cold ground, which could cause irritation or injury to their skin.

[0058] Specifically, by measuring common body shape parameters of breeding pigs and combining them with the site conditions, appropriate height dimensions and proportions are selected to ensure that the length of the support column 5 is sufficient to support the frame at a safe distance from the ground without hindering normal use during actual operation. At the same time, lightweight and durable materials such as stainless steel or aluminum alloy profiles are selected to construct the support column 5 to ensure the strength and stability of the structure. Then, precise installation techniques are used to complete the assembly of the support column 5 and the fixed frame 1.

[0059] In one embodiment, such as Figure 3 As shown, the fixing frame 1 of a boar restraint device with damage reduction function of this application has ventilation holes 13 on its side. These ventilation holes 13 are installed on the side of the fixing frame 1 opposite to the flexible fixing strap 2 and the padding layer 3. Specifically, the ventilation holes 13 are distributed throughout the side area of ​​the fixing frame 1 and are spaced apart to ensure uniform airflow. The diameter of each ventilation hole 13 is designed according to the required airflow, usually between 2 and 5 cm. The ventilation holes 13 are made of weather-resistant material to ensure that they are not easily damaged during long-term use, and are equipped with dustproof nets to prevent debris from entering the interior of the fixing frame 1.

[0060] Although Figure 3 In the diagram, these ventilation holes 13 are shown on the side of the fixed frame 1, but they can also be located on the back of the fixed frame 1, that is, on the side opposite to the flexible fixing strap 2 and the padding layer 3.

[0061] To further optimize airflow performance, the ventilation holes 13 can be adjusted or selected in specific shapes and arrangements according to different environmental conditions. For example, elliptical or rectangular ventilation holes 13 can be selected and staggered along the vertical direction to allow airflow to form circulation within the space, improving the cooling effect. In addition, to adapt to the needs of different scenarios, adjustable dampers can be installed to close or reduce the opening area of ​​the ventilation holes 13 when necessary, so as to better control temperature and air quality.

[0062] Specifically, the ventilation holes 13 can be directly formed into the material of the fixing frame 1 or constructed by embedding precast components, ensuring its sturdiness while facilitating manufacturing and processing. Furthermore, to ensure that the structural strength of the fixing frame 1 is not weakened, when setting multiple large-sized ventilation holes 13, the layout should be rationally planned and appropriate opening methods should be selected, such as efficient processing techniques like laser cutting or CNC milling. At the same time, considering waterproofing and corrosion resistance requirements, all opening edges must be meticulously treated to prevent rust or other forms of aging.

[0063] In one embodiment, a safety buckle 14 is provided at the connection point of the flexible restraint strap 2 of a boar restraint device with damage reduction function according to this application. The flexible restraint strap 2 is one of the main restraint components used to wrap around the key parts of the boar to restrict its movement. The introduction of the safety buckle 14 further ensures the safety and reliability of the restraint operation.

[0064] The safety buckle 14 is located at one end of the flexible fixing belt 2. It automatically locks when the belt completes the tensioning process, and this locking mechanism is triggered when the belt reaches the appropriate tension. Specifically, when the operator adjusts the flexible fixing belt 2 to the appropriate position and tightens it using the adjusting device 4, the metal buckle or plastic structure at one end of the belt will engage with the corresponding locking component at the other end. The two work together to form a locking structure, preventing accidental loosening that may occur due to external interference.

[0065] For example, this automatic locking function can be achieved by designing a spring pressure mechanism. In this implementation, a small spring is installed inside the latch, which is always in a preloaded state when no external force is applied. When the fixing strap reaches the set tightness threshold, the spring inside the latch is pressed into a fine-tuning hole and locked in its current shape; only through a special unlocking operation (such as using a special key or applying greater reverse pressure) can the latch be reopened to release the flexible fixing strap.

[0066] In actual operation, when using this device, the restraint frame 1 is first placed in a suitable position to ensure that the breeding pig has enough space to stand inside. Then, the breeding pig is guided or moved into the restraint frame 1, and the flexible restraint straps 2 are wrapped around the pig's neck, legs, and corresponding parts of its body to restrict excessive movement without causing pressure. The operator can adjust the tightness of the restraint straps using the adjustment device 4, ensuring a close fit without excessively restricting the pig's body. The padding layer 3 installed on the contact surface inside the restraint frame 1 provides additional cushioning for the breeding pig, reducing discomfort caused by prolonged confinement. Simultaneously, the support column 5 raises the restraint frame 1, preventing direct contact between the breeding pig and the ground, thereby reducing the risk of injury. Furthermore, the surface of the flexible restraint straps 2 is equipped with multiple soft protective sleeves 10, which can loosen locally when the breeding pig struggles, further reducing friction and pressure sores on the skin. Through this series of steps, the entire restraint device effectively reduces the risk of injury to the breeding pig during operation, ensuring its safety and comfort.

[0067] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
