[0034] See also Figures 1 to 7 , an animal-powered transport stretcher attachment device, including a fixed seat 1, a supporting mechanism 2, a fixing rope and a lifting mechanism 3.

[0035] The fixing seat 1 is used for being fixedly mounted on the back of livestock, and the fixing seat 1 plays the role of a saddle. Specifically, when the fixing seat 1 is used for being fixed on the back of a horse, the structure of a saddle can be adopted.

[0036] Two support mechanisms 2 are provided, fixedly connected to the ends of the fixed base 1 (i.e., both sides of the fixed base 1 in the figure). The support mechanisms 2 can be bent at multiple locations and can maintain the bent state after bending. After bending, the support mechanisms 2 are in contact with the livestock's back, so that the support mechanisms 2 on both sides and the fixed base 1 in the middle wrap the livestock's back. The support mechanisms 2 can be locked after bending by shape structure or other mechanisms.

[0037] There are two lifting mechanisms 3, which are respectively connected to the support mechanism 2 on the same side, and the lifting frame is used to lift the stretcher. A plurality of fixing ropes (not shown) are provided, which are connected to the end of the support mechanism 2 away from the fixing base 1.

[0038] In this embodiment, the fixed seat 1 is placed on the back of the livestock. By adjusting the supporting mechanisms 2 on both sides, the supporting mechanisms 2 are aligned with the sides of the livestock's back. This reduces the shaking of the stretcher during the transportation of the injured and sick, improves the comfort of the injured and sick during transportation, and reduces the occurrence of secondary injuries. In addition, the supporting structure, fixed seat 1, and lifting mechanism 3 are rigid as a whole. This allows the entire weight of the livestock carrying the injured and sick to be distributed across the livestock's back by the device, reducing damage to the livestock. In contrast, the traditional method of fixing two stretchers with ropes on both sides of the livestock's back, the flexible connection can cause the stretcher to squeeze towards the middle of the livestock, causing livestock injuries.

[0039] In addition, fur can be placed between the fixing seat 1 and the back of the livestock to avoid damage to the livestock.

[0040] In one embodiment, the support mechanism 2 includes a bending component 21 and a locking component 22 .

[0041] The bending assembly 21 is bendable. The bending method of the bending assembly 21 can be a flexible bendable structure or a plurality of rigid parts hinged in sequence. There are two sets of bending assemblies 21 arranged in parallel with each other. The two sets of bending assemblies 21 are in contact with the back of the livestock at the same time to prevent a single set of bending assemblies 21 from shaking like a rope and being unreliable. The two ends of the bending assembly 21 ( Figure 2 The upper and lower ends of the bracket are respectively connected to the fixing seat 1 and the lifting mechanism 3.

[0042] The locking assembly 22 is connected to the bending assembly 21 and is used to lock the bending assembly 21 after it is bent. The bending assembly 21 is bent to form a certain angle, and after the locking assembly 22 locks it, the bending assembly 21 is maintained at the angle.

[0043] In this embodiment, the fixing seat 1 is placed on the back of an animal, and the bending component 21 fits against the back of the animal under the action of gravity and is then locked by the locking component 22 .

[0044] In one embodiment, the bending assembly 21 includes a transition member 211 , a first connecting rod 212 , and a second connecting rod 213 .

[0045] The transition member 211 is provided with one or more coaxially arranged first and second inward-rotating sleeves 211b, 211c, and a fixed sleeve 211a. The fixed sleeve 211a is rotatably mounted on opposite ends of the first and second inward-rotating sleeves 211b, 211c. Two annular retaining grooves 211d are defined on the inner wall of the fixed sleeve 211a. Restricting rings 211e are sleeved on the outer walls of the first and second rotating sleeves. The two retaining rings 211e are respectively loosely fitted into the two annular retaining grooves 211d on the inner wall of the fixed sleeve 211a, allowing the first and second inward-rotating sleeves 211b, 211c to rotate around a fixed axis within the fixed sleeve 211a.

[0046] At least one first connecting rod 212 is provided, and at least one second connecting rod 213 is provided. The first connecting rod 212 and the second connecting rod 213 are arranged in an interval (interval arrangement means repeated arrangement in the following order: one first connecting rod 212, one second connecting rod 213, one first connecting rod 212, one second connecting rod 213, etc.). A transition member 211 is located between adjacent first connecting rods 212 and second connecting rods 213, and adjacent first connecting rods 212 and second connecting rods 213 are connected by a transition member 211. The end of the first connecting rod 212 is connected to the first inward-rotating sleeve 211b, and the end of the second connecting rod 213 is connected to the second inward-rotating sleeve 211c.

[0047] In this embodiment, the adjacent first connecting rod 212 and the second connecting rod 213 rotate around the axis of the transition member 211 therebetween to form a certain angle, resulting in bending.

[0048] In one embodiment, the locking assembly 22 includes a locking prism 221 and a locking rod 222 .

[0049] The inner holes of the first inwardly rotating sleeve 211b and the second inwardly rotating sleeve 211c are both prismatic holes 211f, and the locking assembly 22 is provided with multiple groups corresponding to the transition member 211;

[0050] There are two locking prisms 221, which respectively fit with the inner wall of the first inner rotating sleeve 211b on both sides and slide along the center line. The locking prisms 221 slide with the prismatic hole 211f. Figure 3 The upper and lower ends of the locking rod 222 are respectively connected to the locking prisms 221 on both sides. The diameter of the locking rod 222 is smaller than the diameter of the locking prism 221. The connection between the locking prism 221 and the locking rod 222 is a prismatic boss (the cross-section of the prismatic boss gradually decreases) structure, which facilitates the transition and also plays a guiding role, making it easy to enter the prismatic hole 211f of the second inward rotating sleeve 211c.

[0051] In this embodiment, the locking rod 222 is pushed to move axially, and the locking prism 221 slides and is located in the prismatic holes 211f of the first inward-rotating sleeve 211b and the second inward-rotating sleeve 211c at the same time, thereby preventing the first inward-rotating sleeve 211b from rotating relative to the second inward-rotating sleeve 211c, thereby achieving locking.

[0052] In one embodiment, the locking assembly 22 further includes a force storage member 223 , which includes a mounting rod 223 a , a driving assembly 224 , an actuating rod 223 b , an actuating ring 223 c and a mating ring 223 d .

[0053] The two ends of the mounting rod 223a are respectively connected to the first connecting rod 212 or the second connecting rod 213 on both sides, the driving assembly 224 is connected to the mounting rod 223a, two executing rods 223b are provided, and the executing rods 223b are respectively connected to the two ends of the driving assembly 224, two executing rings 223c are provided, and the two executing rings 223c are both slidably mounted on the locking rod 222, and the executing ring 223c is connected to the executing rod 223b on the same side, and two mating rings 223d are provided, and the mating rings 223d are both sleeved on the locking rod 222.

[0054] The two execution rings 223c are located between the two matching rings 223d; the driving assembly 224 pushes the execution ring 223c on one side to apply a continuous force to the matching ring 223d.

[0055] In this embodiment, the prismatic holes 211f in the first inward-rotating sleeve 211b and the second inward-rotating sleeve 211c are not aligned at all times, and the locking prism 221 cannot complete the locking every time. Therefore, a driving assembly 224 is provided to push the single-sided execution ring 223c to apply a continuous force to the mating ring 223d, thereby applying a continuous force to the locking rod 222. Once the angle between the first connecting rod 212 and the second connecting rod 213 is slightly adjusted manually, the prismatic holes 211f of the first inward-rotating sleeve 211b and the second inward-rotating sleeve 211c are aligned, and the locking rod 222 moves under the above-mentioned force, and the locking prism 221 can quickly complete the locking.

[0056] In one embodiment, the drive assembly 224 includes a drive block 224a, a guide rod 224b, and a square rod 224c.

[0057] A square placement hole 224d is provided on the driving block 224a, and square blocking rings 224e that shrink inward are provided at both ends of the placement hole. Two square rods 224c are provided, and the ends of the square rods 224c are respectively slid from the two square blocking rings 224e and inserted into the placement holes. The other ends of the two square rods 224c are connected to the actuator rod 223b.

[0058] A reversing ring 224f is sleeved on the outer periphery of the opposite ends of the two square rods 224c, and a guide hole 224g of the center line of the cylinder is opened at the opposite ends of the two square rods 224c. The two ends of the guide rod 224b are slidably inserted into the two guide holes 224g, and a guide spring 224h is sleeved on the guide rod 224b, and the two ends of the guide spring 224h are respectively abutted against the ends of the two square rods 224c; U-shaped channels 224i are opened on both sides of the inner wall of the placement hole to communicate with it; an elastically retractable U-shaped block 224j is provided in the U-shaped channel 224i; a reversing wedge block 224k is respectively connected to the two ends of the U-shaped block 224j; the inclined surface of the reversing wedge block 224k faces the orifice of the placement hole; there are two reversing wedge blocks 224k on both sides of one of the reversing rings 224f.

[0059] In this embodiment, the U-shaped block 224j can be elastically extended and retracted from the U-shaped channel 224i; Figure 5 , pushing the lower square rod 224c upward, the reversing ring 224f on the lower square rod 224c abuts against the reversing wedge block 224k below the two U-shaped blocks 224j, causing the two U-shaped blocks 224j to retract. As the U-shaped block 224j retracts, the upper reversing ring 224f is no longer constrained and can move upward, and then the lower reversing ring 224f2 enters the encirclement of the two U-shaped blocks 224j; the lower reversing ring 224f abuts against the upper end of the reversing wedge block 224k. At this time, the lower square rod 224c exerts an external force on the upper square rod 224c through the guide spring 224h, and the upper direction rod drives the external locking rod 222 to move upward through the upper actuator rod 223b; similarly, operating in the opposite direction once can drive the locking rod 222 to move downward; the application of unidirectional external force can be achieved, and the external force application is continuous until the locking rod 222 is driven into place.

[0060] In addition, the elastic expansion and contraction method of the U-shaped block 224j can be referred to Figure 5 The U-shaped block 224j is divided into two parallel cross bars and a bottom plate; a hole is opened on the cross bar; a positioning rod is provided at the bottom of the U-shaped channel 224i corresponding to the hole of the cross bar; one end of the positioning rod is slidably inserted into the hole on the corresponding cross bar; and then a telescopic spring is provided on the positioning rod, and the two ends of the telescopic spring are respectively connected to the cross bar and the bottom of the U-shaped channel 224i.

[0061] In one embodiment, the lifting mechanism 3 includes a lifting bar 31 , a telescopic rod 32 and a clamping assembly 33 .

[0062] Both ends of the lifting bar 31 are connected to the first connecting rod 212 or the second connecting rod 213 respectively. The lifting bar 31 is provided with a receiving groove 311 along its length.

[0063] Two telescopic rods 32 are provided, and the ends of the telescopic rods 32 are hinged to the bottom of the receiving slot 311 .

[0064] Preferably, the telescopic rod 32 comprises a square telescopic inner rod 321 and a square telescopic outer rod 322. The end of the square telescopic inner rod 321 is hinged to the bottom of the storage slot 311; the square telescopic outer rod 322 is slidably mounted on the square telescopic inner rod 321 through a hole at one end. The square telescopic inner rod 321 is provided with an elastically retractable protrusion 323; the square telescopic outer rod 322 has a telescopic hole corresponding to the protrusion 323, which fits into the protrusion 323. Its structure is similar to that of an umbrella pole.

[0065] There are two clamping assemblies 33, which are connected to the end of the telescopic rod 32 away from the lifting bar 31. The clamping assemblies 33 are used to clamp the stretcher. The clamping assemblies 33 can clamp the stretcher by shape or by mechanical structure.

[0066] In this embodiment, the telescopic rod 32, which supports the stretcher, can be retracted and rotated into the storage slot 311 when not in use, taking up less space. When the telescopic rod 32 is extended, the side walls of the storage slot 311 can also provide support for the telescopic rod 32, thereby allowing the telescopic rod 32 to be extended to a maximum of 90 degrees, which is beneficial for supporting the stretcher.

[0067] In one embodiment, the clamping assembly 33 includes a clamping block 331 , a slider 332 , a tension spring 333 and a blocking column 334 .

[0068] The clamping block 331 is fixedly connected to the telescopic rod 32. The clamping block 331 is provided with a mounting cavity 335. The clamping block 331 is provided with a limit opening 336. The limit opening 336 is connected to the mounting cavity 335. The lateral dimension of the limit opening 336 is smaller than that of the mounting cavity 335. The slider 332 is slidably installed in the mounting cavity 335. The two ends of the tension spring 333 are respectively connected to the side wall of the mounting cavity 335 and the slider 332. The tension spring 333 applies tension to the slider 332. The blocking column 334 is connected to the slider 332. The blocking column 334 is away from the end of the slider 332 ( Figure 7 The upper end of the slider (in the middle) passes through the stop opening 336 and is connected to a triangular block 337. The stop opening 336 restricts the slider 332 from escaping from the mounting cavity 335 and allows it to slide only within the cavity 335. Triangular block 337 has a triangular cross-section, and its upper end faces an inclined surface facing the telescopic rod 32. Its function is similar to that of a wedge-shaped block. When the stretcher lands on triangular block 337, it guides it down onto the telescopic rod 32.

[0069] In addition, two L-shaped openings 312 are provided on the lifting bar 31, and the L-shaped openings 312 are connected to the receiving groove 311. Figure 6As shown. In this embodiment, after the telescopic rod is extended, when the stretcher is placed, one of the two long rods of the stretcher is placed on the telescopic rod at one end of the lifting bar. The other long rod of the stretcher abuts against the upper inclined surface of the triangular block, thereby pushing the slider to slide and stretching the tension spring. When the long rod falls onto the telescopic rod, the slider drives the blocking column toward the long rod under the action of the tension spring, and the triangular block clamps the long rod. The clamping assembly is not only used to clamp the stretcher, but also has a fixing effect on the telescopic rod when it is retracted into the storage slot. When the telescopic rod is retracted into the storage slot, the blocking column engages with the L-shaped opening to prevent the telescopic rod from slipping out of the storage slot.
