DETAILED DESCRIPTION

[0048] The technical solutions of the present invention are further described in detail below through examples and in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0049] In animal husbandry and veterinary work, safely securing cattle is a critical step in ensuring the smooth implementation of inspections, treatments, or procedures. Cattle are large and powerful, and improper securing can result in injuries to personnel or stress-related injuries to the cattle themselves. Cattle health checks typically require securing their heads and bodies for temperature measurements, heart and lung auscultation, and observation of oral or surface lesions. Furthermore, securing the cattle's bodies during vaccinations and drug injections is necessary to prevent needle breakage from struggling due to pain. For example, securing the limbs of cattle is also necessary for hoof care, dehorning, or assisted childbirth.

[0050] According to existing technologies, cattle limbs are typically secured using a cattle stall or restraint. This involves driving the cattle into a dedicated restraint, where side panels or splints are used to secure the cattle's body, restricting their forward, backward, or left or right movement. However, existing restraints are typically fixed in a specific location, requiring the cattle to be driven into the restraint before being secured. This method is time-consuming and labor-intensive, and may also cause injury to the cattle.

[0051] To address the above-mentioned problems, the present invention aims to provide a non-injurious and flexible fixation device for cattle, used to restrict the movement of cattle limbs. The flexible fixation device comprises a bracket assembly capable of surrounding the cattle and an airbag assembly disposed on the bracket assembly. The bracket assembly comprises a plurality of vertical support rods and transverse support rods connecting the vertical support rods. The airbag assembly comprises an airbag unit 10 disposed on the transverse support rods, an air pump for inflating the airbag unit 10, and an air tube 11 connecting the air pump and the airbag unit 10.

[0052] The bracket assembly includes at least four vertical support rods arranged in a rectangular shape, and a transverse support rod is arranged between the two vertical support rods in the length direction. The vertical support rods and the transverse support rods together form a semi-enclosed frame structure. The cow can be placed inside the semi-enclosed frame structure. After inflation, the airbag unit 10 contacts the cow's limbs to limit the movement of the cow's limbs.

[0053] In this embodiment, Figure 1 、 Figure 5 As shown, the flexible fixing device of this embodiment can be moved into the cattle pen to fix the cattle, thereby improving the efficiency of cattle maintenance. Specifically, the vertical support rod refers to the support rod that is perpendicular to the ground when in use, and the horizontal support rod refers to the support rod that is parallel to the ground when in use.

[0054] The rack assembly includes at least four vertical support rods, which form a rectangle at the four corners. A transverse support rod connects the two vertical support rods in the longitudinal direction and the two vertical support rods at the rear end in the width direction. The vertical and transverse support rods form a semi-enclosed structure, with an open end in the width direction, allowing cattle to enter the rack assembly.

[0055] In some embodiments, the airbag unit 10 includes a rigid backplate and an extension region made of a flexible material. The backplate contacts the transverse support rods. When inflated, the extension region extends toward the center of the support assembly, allowing it to conform to the cow's limbs. The air pump can be an electric air pump. The air tube 11 includes a main pipe body and a diverter connector. The diverter connector can connect multiple main pipe bodies. The air tube 11 can connect the air pump and all airbag units 10.

[0056] During the specific implementation process, the support assembly can be moved around the cow to surround the cow, and then the air pump is used to inflate the airbag unit 10. The multiple airbags installed on the transverse support rods squeeze and fix the cow from all sides. The airbag unit 10 can be placed near the cow's limbs to prevent the cow from struggling and causing harm to people when the limbs are stressed. At this time, the cow can be maintained. After the work is completed, the airbag unit 10 can be deflated and the support unit can be removed. The airbag can be deflated through the deflation valve installed on the airbag unit 10 or the trachea 11.

[0057] Furthermore, the bracket assembly includes six vertical support rods arranged in a rectangular shape, including four corner support rods 12 arranged at the four corners of the rectangle and two side support rods 13 arranged between the two corner support rods 12 in the length direction; a transverse support rod connects the two corner support rods 12 in the length direction and the side support rod 13 between the two corner support rods 12;

[0058] The airbag assembly includes four airbag units 10, one of which is provided on each of the transverse support bars between the corner support bars 12 and the side support bars 13. After inflation, the four airbag units 10 contact the cow from both sides of its limbs in the direction of its head and tail.

[0059] The two ends of the bracket assembly are the front end and the rear end respectively. A connecting rod is provided between the two corner support rods 12 at the rear end. The air pump is provided on the connecting rod. The air pipe 11 connects the air pump and the four airbag units 10.

[0060] In this embodiment, the bracket assembly includes 6 vertical support rods, including 4 corner support rods 12 arranged at the four corners of the rectangle and 2 side support rods 13 arranged between the two corner support rods 12 in the length direction. The 6 vertical support rods are arranged to form a rectangle, including 2 long sides in the length direction and 2 short sides in the width direction, and the side support rod 13 is in the middle position in the length direction.

[0061] The airbag assembly includes four airbag units 10, positioned in pairs on opposite sides of the lengthwise direction. Specifically, each airbag unit 10 can be positioned on a transverse support rod between a corner support rod 12 and a side support rod 13. When inflated, the four airbag units 10 contact the cow from both sides of its limbs toward its head and tail. The inflated airbag units 10 primarily serve to support the cow's limbs.

[0062] In some embodiments, the airbag unit 10 can move on the transverse support rod to adjust its fore-aft position, adjusting its position to accommodate the position of the cow's limbs before inflation. Specifically, the transverse support rod is provided with a sleeve slider 20, which sleeves onto the outside of the transverse support rod and can slide along the length of the transverse support rod. The back panel of the airbag unit 10 is mounted on the sleeve slider 20.

[0063] In some embodiments, two transverse support rods are arranged parallel to the vertical support rod, and the back plate of the airbag unit 10 is installed on the two transverse support rods. After the airbag unit 10 is inflated, it can prevent the airbag unit 10 from deflecting or rotating.

[0064] The bracket assembly has a front and rear end, with a connecting rod between the two corner support rods 12 at the rear end. The air pump is mounted on the connecting rod, and the air pipe 11 connects the air pump and the four airbag units 10. The vertical and horizontal support rods of the bracket assembly form a semi-enclosed structure. The front end of the bracket assembly is open, allowing cattle to enter the interior of the bracket assembly through the front end.

[0065] Furthermore, a detachable head restraint assembly is provided between the two corner support bars 12 at the front end of the bracket assembly; the head restraint assembly includes two mouth connecting straps 21 for connecting the two corner support bars 12, two mouth airbags 22 provided between the two mouth connecting straps 21 and connected to the two mouth connecting straps 21 respectively, and two sliding buckles 23 sleeved on the outside of the two mouth connecting straps 21 and the two mouth airbags 22;

[0066] When the mouth airbag 22 is deflated, the sliding buckle 23 can slide on the mouth connecting belt 21 along the length direction of the mouth connecting belt 21; when the mouth airbag 22 is inflated, the airbag squeezes the sliding buckle 23 from both sides and thus cannot slide along the length direction of the mouth connecting belt 21;

[0067] The two mouth connecting belts 21 and the two mouth airbags 22 can be placed on the upper and lower sides of the cow's mouth respectively. When the mouth airbags 22 are deflated, the two sliding buckles 23 can be moved to the left and right sides of the cow's mouth respectively, and then inflating the mouth airbags 22 can limit the position of the cow's mouth. The mouth airbags 22 are connected to the air pump through the trachea 11.

[0068] In this embodiment, Figure 1 、 Figure 12 As shown, the head restraint assembly is used to connect with the cow's head to restrict the movement of the cow's head, preventing the cow from swinging its head in response to stress and causing harm to nearby people. Specifically, the head restraint assembly is detachably mounted at the front end of the bracket assembly. Before the bracket assembly is moved to a position surrounding the cow, the head restraint assembly is separated or partially separated from the front end of the bracket assembly, allowing the cow to enter the bracket assembly through an opening at the front end of the bracket assembly. After the bracket assembly is moved to a position surrounding the cow, the head restraint assembly is connected to the bracket assembly.

[0069] The mouth connecting strap 21 can be made of a textile material with low ductility, and the mouth airbag 22 can be made of a flexible and ductile material. The mouth airbag 22 can be installed on the mouth connecting strap 21 by bonding. One end of the mouth connecting strap 21 can be fixed to one corner support rod 12 by a locking member, and the other end of the mouth connecting strap 21 is connected to the other corner support rod 12 by a buckle or other detachable means. The sliding buckle 23 is a ring that is sleeved on the two mouth connecting straps 21 and the outside of the mouth airbag 22. Before the mouth airbag 22 is inflated, it can slide on the mouth connecting strap 21 to adjust its position. After the mouth airbag 22 is inflated, both sides of the sliding buckle 23 are squeezed by the inflation of the mouth airbag 22, so the position is fixed after inflation and cannot be adjusted.

[0070] When in use, the bracket assembly is first moved to a position surrounding the cow, with the cow inside the bracket assembly. The two ends of the mouth connecting belt 21 are then connected to the corner support rods 12. The two sliding buckles 23 on the mouth connecting belt 21 are then moved to the positions on both sides of the cow's mouth. The two mouth connecting belts 21 are then separated and sleeved on the upper and lower sides of the cow's mouth. The positions of the two sliding buckles 23 are simultaneously adjusted so that they are on the left and right sides of the cow's mouth. Finally, the mouth airbag 22 is controlled to inflate, and the position of the sliding buckle 23 is fixed. At the same time, the mouth connecting belt 21 can fix the cow's head. When the cow's head swings, the mouth connecting belt 21 can form a restraining force. The mouth airbag 22 is mainly used to connect the mouth connecting belt 21 to the cow in a flexible manner to avoid causing discomfort to the cow.

[0071] Furthermore, the head restraint assembly further includes a head connecting strap 24 and a head airbag 25 disposed on the head connecting strap 24; the two ends of the head connecting strap 24 are respectively connected to two sliding buckles 23, and the head airbag 25 can be placed between the head connecting strap 24 and the cow's head and limbs; the head airbag 25 is connected to the air pump through the trachea 11;

[0072] The head connecting belt 24 and the head airbag 25 can surround both sides of the cow's head and the back of the cow's neck. After the head airbag 25 is inflated, it can limit the position of the mouth airbag 22 to prevent the mouth airbag 22 from falling off.

[0073] In this embodiment, the head airbag 25 and the head connecting belt 24 are used to connect the mouth connecting belt 21 from the back of the cow's neck to prevent the mouth connecting belt 21 from falling off. The two ends of the head connecting belt 24 are respectively connected to the two sliding buckles 23.

[0074] In the specific implementation process, Figure 12 As shown, an air tube 11 connects the mouth airbag 22 and the head airbag 25 , and simultaneously inflates and deflates the mouth airbag 22 and the head airbag 25 .

[0075] Furthermore, one end of the nozzle connecting belt 21 is fixedly connected to one corner support rod 12, and the other end of the nozzle connecting belt 21 is movably connected to the other corner support rod 12; the corner support rod 12 is provided with a sleeve slider 20 sleeved on the outside of the corner support rod 12, and the sleeve slider 20 is provided with a first buckle 26, and the end of the nozzle connecting belt 21 is provided with a second buckle 27 matching the first buckle 26;

[0076] Before the mouth airbag 22 is inflated, the mouth connecting belt 21 is in a relaxed state, and the mouth connecting belt 21 and the corner support rod 12 are connected by the first buckle 26 and the second buckle 27; after the mouth airbag 22 is inflated, the mouth connecting belt 21 is tensioned, and the first buckle 26 and the second buckle 27 are locked.

[0077] In this embodiment, Figure 2 、 Figure 13 、 Figure 14 As shown, one end of the nozzle connecting strap 21 is fixedly connected to one corner support rod 12, and the other end of the nozzle connecting strap 21 is movably connected to the other corner support rod 12. The corner support rod 12 is provided with a sleeve slider 20 that sleeves onto the outside of the corner support rod 12. The sleeve slider 20 is provided with a first buckle 26. The end of the nozzle connecting strap 21 is provided with a second buckle 27 that matches the first buckle 26.

[0078] The first buckle 26 is a T-shaped buckle, and the length direction of the buckle is parallel to the length direction of the bracket assembly. The second buckle 27 has a T-shaped slot. The second buckle 27 needs to be inserted into the first buckle 26 from the front or back of the bracket assembly. The force direction of the buckle is the length direction of the mouth connecting belt 21, that is, the width direction of the bracket assembly.

[0079] Before the mouth airbag 22 is inflated, the mouth connecting belt 21 is in a relaxed state, and the mouth connecting belt 21 and the corner support rod 12 are connected by the first buckle 26 and the second buckle 27; after the mouth airbag 22 is inflated, it expands, the mouth connecting belt 21 is tightened, and the first buckle 26 and the second buckle 27 are locked.
