[0002] A syringe is a common medical tool. The process of drawing in and injecting gas or liquid with a needle is called injection. A syringe consists of a barrel with a small hole at the front end and a piston core rod that matches it. It is used to inject a small amount of liquid or extract it from areas that cannot be reached by other methods. When the core rod is pulled out, the liquid or gas is sucked into the barrel through the small hole at the front end, and when the core rod is pushed in, the liquid or gas is extruded.

The output shaft of the driving motor is fixedly connected to the bidirectional threaded rod.

[0014] Further, a method for positioning a syringe for veterinary use in animal husbandry is as follows:

[0015] S1: Narrow the space: The hollow fixing frame drives the limit sliding plate to move synchronously. The limit sliding plate will drive the isosceles trapezoidal plate to move synchronously. The isosceles trapezoidal plate will contact the triangular block. The isosceles trapezoidal plate will cause the fixing spring to undergo compressive deformation. At this time, the isosceles trapezoidal plate slides in the sliding groove. And so on. When the rectangular plate no longer descends, the isosceles trapezoidal plate will no longer move. At this time, the isosceles trapezoidal plate will be stuck on the corresponding triangular block. At this time, the space above the rectangular plate will become smaller, and the pig can be effectively controlled and positioned.

[0016] S2: Clamp the head: The positioning spring will drive the U-shaped mounting plate to descend. The U-shaped mounting plate will stop moving when it touches the back of the pig. At this time, due to the continuous descent of the limit sliding plate, the positioning spring will undergo compressive deformation. At this time, the U-shaped mounting plate will fit more tightly against the back of the pig. The descent of the U-shaped mounting plate will drive the adjusting T-shaped screw rod to descend. The adjusting T-shaped screw rod will drive the L-shaped hollow plate to descend. The L-shaped hollow plate will drive the syringe to descend. When the U-shaped mounting plate stops moving, the position of the syringe is exactly at the neck of the pig.

[0017] S3: Fix the syringe: insert the syringe into the L-shaped hollow plate, and insert the needle into the pig's neck, then rotate the T-shaped fixing screw, which drives the rubber blocks to clamp the syringe to ensure the stability of the syringe and prevent it from rotating, and then push the drug in to ensure the stability of the syringe during the injection process;

[0018] S4: Releasing livestock: After the injection is completed, the drive motor is started again to separate the two L-shaped clamping plates. At this time, the rectangular block is slid downward. The rectangular block will contact the two T-shaped plates during the descent process. The T-shaped plates will move away from each other under the action of their inclined surfaces until the limiting holes on the rectangular block contact the two T-shaped plates. At this time, the T-shaped plates will slide into the limiting holes to complete the initial fixation of the rectangular block. During the descent of the rectangular block, the connecting rod will be driven down, and the connecting rod will drive the two isosceles trapezoidal plates to approach each other. The isosceles trapezoidal plates will slide into the sliding groove. At this time, the isosceles trapezoidal plates will not lock the triangular block, and then pull the rectangular block away from the limiting sliding plate. The rectangular block will drive the limiting slide plate to move, and the limiting slide plate will drive the hollow fixing frame to move. When the limiting slide plate moves to the initial position, the limiting slide plate is pulled out from the hollow fixing frame to release the injected pig.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a syringe positioning device for animal husbandry and veterinary medicine. The pig is driven onto a fixed frame, and then a limit slide is inserted into the hollow fixed frame. When the pig stands on the rectangular plate, the rectangular plate descends under the action of gravity. At this time, the force spring is compressed and deformed, and the rectangular plate drives the special-shaped rod to descend. The special-shaped rod drives the limit sliding plate to descend. The limit sliding plate drives the synchronous plate to descend. The synchronous plate drives the long plate to descend. The long plate drives the hollow fixed frame to move in a direction close to the limit sliding plate. The hollow fixed frame drives the limit slide to move synchronously. The limit slide will drive The isosceles trapezoidal plate moves synchronously, and the isosceles trapezoidal plate will contact the triangular block. The isosceles trapezoidal plate will cause the fixed spring to be compressed and deformed. At this time, the isosceles trapezoidal plate will slide in the sliding groove first, and so on. When the rectangular plate no longer drops, the isosceles trapezoidal plate will no longer move. At this time, the isosceles trapezoidal plate will be stuck on the corresponding triangular block. At this time, the space above the rectangular plate will become smaller, which can effectively control and position the pig, avoiding the tingling sensation during injection and causing the pig to become irritable, causing it to move around and break the needle of the syringe, affecting the injection process;

[0021] (2) In a syringe positioning device for livestock and veterinary use according to the present invention, during the downward movement of the limit sliding plate, the positioning spring will be driven downward, and the positioning spring will drive the U-shaped mounting plate downward. When the U-shaped mounting plate touches the back of the pig, it will stop moving. At this time, due to the continuous downward movement of the limit sliding plate, the positioning spring will undergo compressive deformation. At this time, the U-shaped mounting plate will fit more closely to the back of the pig. The downward movement of the U-shaped mounting plate will drive the adjusting T-shaped screw downward, and the adjusting T-shaped screw will drive the L-shaped hollow plate downward. The L-shaped hollow plate will drive the syringe downward. When the U-shaped mounting plate stops moving, the position of the syringe is exactly at the neck of the pig. The position of the syringe can be positioned at the neck of the pig according to the height of the pig, thereby improving the positioning efficiency and accuracy.

[0022] (3) In a syringe positioning device for livestock and veterinary use according to the present invention, then start the driving motor. The driving motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod will drive two L-shaped clamping plates to approach each other until the two L-shaped clamping plates clamp and position the head of the pig, ensuring the stability of the pig's head during injection and avoiding the difficulty of injection caused by the shaking of the pig's head during injection. After the positioning of the syringe is completed, then rotate the adjusting T-shaped screw. The adjusting T-shaped screw drives the L-shaped hollow plate to make fine adjustments to ensure that the syringe is aligned with the neck of the pig. Insert the syringe into the L-shaped hollow plate and insert the needle into the neck of the pig. Then rotate the T-shaped fixing screw. The T-shaped fixing screw drives the rubber blocks to approach each other to clamp the syringe, ensuring the stability of the syringe and preventing it from rotating. Then push in the drug to ensure the stability of the syringe during injection and improve the success rate of injection.

[0023] (4) In a syringe positioning device for livestock and veterinary use according to the present invention, after the injection is completed, start the driving motor again to separate the two L-shaped clamping plates. At this time, slide the rectangular block downward. During the downward movement of the rectangular block, it will contact the two T-shaped plates. The T-shaped plates will move away from each other under the action of their inclined surfaces until the limit holes on the rectangular block contact the two T-shaped plates. At this time, the T-shaped plates will slide into the limit holes to complete the preliminary fixation of the rectangular block. During the downward movement of the rectangular block, it will drive the connecting rod downward, and the connecting rod will drive the two isosceles trapezoidal plates to approach each other. The isosceles trapezoidal plates will slide into the sliding grooves. At this time, the isosceles trapezoidal plates will not lock the triangular block. Then pull the rectangular block in the direction away from the limit sliding plate. The rectangular block will drive the limit sliding plate to move, and the limit sliding plate will drive the hollow fixing frame to move. When the limit sliding plate moves to the initial position, pull out the limit sliding plate from the hollow fixing frame to release the pig after the injection is completed.

C-shaped limiting plates 2 are fixedly installed on the left inner wall and the right inner wall of the fixed frame 1 respectively. A plurality of triangular blocks 3 are fixedly installed on the inner walls of the two C-shaped limiting plates 2 close to each other. Limiting chutes 4 are respectively opened on the top inner wall and the bottom inner wall of the two triangular blocks 3. It also includes:

[0039] The limiting mechanism 5, the limiting mechanism 5 includes a hollow fixed frame 501 arranged in a plurality of limiting chutes 4, the hollow fixed frame 501 is slidably connected with the plurality of limiting chutes 4, and limiting springs 502 are respectively fixedly installed on the inner walls of the backs of the two U-shaped limiting plates 2. The front ends of the two limiting springs 502 are fixedly connected with the hollow fixed frame 501. A limiting slide plate 503 is slidably installed in the hollow fixed frame 501. The limiting slide plate 503 is adapted to the plurality of limiting chutes 4. Two sliding grooves 504 are formed in the limiting slide plate 503. Fixed springs 505 are respectively fixedly installed on the inner walls of the mutually remote sides of the two sliding grooves 504. Isosceles trapezoidal plates 506 are respectively fixedly installed at the mutually remote ends of the two fixed springs 505. The mutually remote ends of the two isosceles trapezoidal plates 506 respectively extend outside the two sliding grooves 504 and are respectively slidably connected with the two sliding grooves 504.

[0040] As Figure 3 、 Figure 5 and Figure 6 shown, connecting rods 507 are respectively rotatably installed on the fronts of the two isosceles trapezoidal plates 506. A U-shaped slide plate 508 is fixedly installed on the front of the limiting slide plate 503. A rectangular block 509 is slidably sleeved on the U-shaped slide plate 508. The rectangular block 509 is hinged with the two connecting rods 507. Two limiting holes 510 are respectively formed on the left side and the right side of the rectangular block 509.

[0041] During the process of the rectangular block 509 descending, it will drive the connecting rods 507 to descend. The connecting rods 507 will drive the two isosceles trapezoidal plates 506 to approach each other. The isosceles trapezoidal plates 506 will slide into the sliding grooves 504. At this time, the isosceles trapezoidal plates 506 will not lock the triangular blocks 3.

[0042] As Figure 2 and Figure 6 shown, a fixing mechanism 6 is arranged on the front of the limiting slide plate 503. The fixing mechanism 6 includes two strip-shaped blocks 601 fixedly installed on the front of the limiting slide plate 503. T-shaped plates 602 are respectively slidably penetrated through the two strip-shaped blocks 601. The mutually approaching ends of the two T-shaped plates 602 are both in the shape of isosceles trapezoids. Expansion springs 603 are respectively sleeved on the two T-shaped plates 602. The mutually remote ends of the two expansion springs 603 are respectively fixedly connected with the two T-shaped plates 602. The mutually approaching ends of the two expansion springs 603 are respectively fixedly connected with the two strip-shaped blocks 601. A rectangular groove 604 is formed on the bottom inner wall of the fixed frame 1. A stress spring 605 is fixedly installed on the bottom inner wall of the rectangular groove 604. The top end of the stress spring 605 is fixedly installed with a rectangular plate 606. The rectangular plate 606 is slidably connected with the rectangular groove 604.

[0043] Drive the pig onto the fixing frame 1, then insert the limiting sliding plate 503 into the hollow fixing frame 501. When the pig stands on the rectangular plate 606, under the action of gravity, the rectangular plate 606 descends, and at this time, the stress spring 605 undergoes compressive deformation.

[0044] As Figure 2 shown, a special-shaped rod 607 is fixedly installed on the back of the rectangular plate 606. The special-shaped rod 607 passes through the fixing frame 1 and is slidably connected to the fixing frame 1. A limiting sliding plate 608 is fixedly installed at the bottom end of the special-shaped rod 607. The left and right sides of the limiting sliding plate 608 respectively extend into the C-shaped fixing plate 101 and are slidably connected to the C-shaped fixing plate 101. A synchronous plate 609 is fixedly installed on the front surface of the limiting sliding plate 608. A long plate 610 is hingedly installed at the bottom end of the synchronous plate 609. The bottom end of the long plate 610 is hinged to the hollow fixing frame 501.

[0045] The rectangular plate 606 drives the special-shaped rod 607 to descend, the special-shaped rod 607 drives the limiting sliding plate 608 to descend, the limiting sliding plate 608 drives the synchronous plate 609 to descend, the synchronous plate 609 will drive the long plate 610 to descend, and the long plate 610 will drive the hollow fixing frame 501 to move towards the direction close to the limiting sliding plate 608.

[0046] As Figure 2 、 Figure 7 and Figure 8 shown, a positioning mechanism 7 is arranged at the bottom end of the limiting sliding plate 608. The positioning mechanism 7 includes a positioning spring 701 fixedly installed at the bottom end of the limiting sliding plate 608. A C-shaped mounting plate 702 is fixedly installed at the bottom end of the positioning spring 701. Two limiting T-shaped round rods 703 are fixedly installed at the top of the C-shaped mounting plate 702. Both of the two limiting T-shaped round rods 703 pass through the limiting sliding plate 608 and are slidably connected to the limiting sliding plate 608. A strip-shaped mounting groove 704 is formed in the C-shaped mounting plate 702. An adjusting T-shaped screw rod 705 is rotatably installed in the strip-shaped mounting groove 704. The front end of the adjusting T-shaped screw rod 705 extends outside the C-shaped mounting plate 702. An L-shaped hollow plate 706 is sleeved on the adjusting T-shaped screw rod 705.

[0047] During the descending process of the limiting sliding plate 608, it will drive the positioning spring 701 to descend, and the positioning spring 701 will drive the C-shaped mounting plate 702 to descend. When the C-shaped mounting plate 702 touches the pig's back, it will stop moving. At this time, due to the continuous descent of the limiting sliding plate 608, the positioning spring 701 will undergo compressive deformation, and at this time, the C-shaped mounting plate 702 will fit more tightly against the pig's back.

[0048] As Figure 8As shown, a syringe 707 is slidably installed through an L-shaped hollow plate 706. Two rubber blocks 708 are slidably installed in the L-shaped hollow plate 706. One end of each of the two rubber blocks 708 close to each other is in contact with the syringe 707. T-shaped fixing screws 709 are respectively rotatably installed on the sides of the two rubber blocks 708 away from each other. One end of each of the two T-shaped fixing screws 709 away from each other extends outside the L-shaped hollow plate 706 and is threadedly connected to the L-shaped hollow plate 706.

[0049] The lowering of the U-shaped mounting plate 702 will drive the adjusting T-shaped screw 705 to lower. The adjusting T-shaped screw 705 will drive the L-shaped hollow plate 706 to lower. The L-shaped hollow plate 706 will drive the syringe 707 to lower. When the U-shaped mounting plate 702 stops moving, the position of the syringe 707 is exactly at the neck of the pig at this time. The syringe 707 can be positioned at the neck of the pig according to the height of the pig, thereby improving the positioning efficiency and accuracy.

[0050] As Figure 1 and Figure 2 As shown in FIGS. and, a clamping mechanism 8 is provided on the back surface of the fixing frame 1. The clamping mechanism 8 includes a strip-shaped long groove 801 opened on the back surface of the fixing frame 1. A bidirectional threaded rod 802 is rotatably installed in the strip-shaped long groove 801. The right end of the bidirectional threaded rod 802 extends outside the fixing frame 1. Two L-shaped clamping plates 803 are threadedly sleeved on the bidirectional threaded rod 802. A driving motor 804 is fixedly installed on the right side of the fixing frame 1. The output shaft of the driving motor 804 is fixedly connected to the bidirectional threaded rod 802.

[0051] Then start the driving motor 804. The driving motor 804 drives the bidirectional threaded rod 802 to rotate. The bidirectional threaded rod 802 will drive the two L-shaped clamping plates 803 to approach each other until the two L-shaped clamping plates 803 clamp and position the head of the pig, ensuring the stability of the pig's head during injection and avoiding the difficulty of injection caused by the shaking of the pig's head during injection.

[0052] As Figure 1 - Fig. 9 As shown in FIGS. -,, a method for positioning a syringe for veterinary use in animal husbandry is as follows:

[0053] S1: Narrow the space: The hollow fixing frame 501 drives the limit sliding plate 503 to move synchronously. The limit sliding plate 503 will drive the isosceles trapezoidal plate 506 to move synchronously. The isosceles trapezoidal plate 506 will contact the triangular block 3. The isosceles trapezoidal plate 506 will cause the fixing spring 505 to undergo compressive deformation. At this time, the isosceles trapezoidal plate 506 slides in the sliding groove 504. And so on. When the rectangular plate 606 no longer descends, the isosceles trapezoidal plate 506 will no longer move. At this time, the isosceles trapezoidal plate 506 will be stuck on the corresponding triangular block 3. At this time, the space above the rectangular plate 606 will become smaller, and the pig can be effectively controlled and positioned.

[0054] S2: Clamping head: The positioning spring 701 drives the U-shaped mounting plate 702 to descend. The U-shaped mounting plate 702 stops moving when it touches the back of the pig. At this time, since the limit sliding plate 608 continues to descend, the positioning spring 701 will undergo compressive deformation. At this time, the U-shaped mounting plate 702 will fit more closely to the back of the pig. The descent of the U-shaped mounting plate 702 drives the adjusting T-shaped screw 705 to descend. The adjusting T-shaped screw 705 drives the L-shaped hollow plate 706 to descend. The L-shaped hollow plate 706 drives the syringe 707 to descend. When the U-shaped mounting plate 702 stops moving, the syringe 707 is exactly positioned at the neck of the pig.

[0055] S3: Fixing the syringe 707: Insert the syringe 707 into the L-shaped hollow plate 706, and insert the needle into the neck of the pig. Then rotate the T-shaped fixing screw 709. The T-shaped fixing screw 709 drives the rubber blocks 708 to move closer to each other to clamp the syringe 707, ensuring that the syringe 707 is stable and does not rotate. Then push in the drug to ensure the stability of the syringe 707 during the injection process.

[0056] S4: Releasing the livestock: After the injection is completed, start the drive motor 804 again to separate the two L-shaped clamping plates 803. At this time, slide the rectangular block 509 downward. During the descent of the rectangular block 509, it will contact the two T-shaped plates 602. The T-shaped plates 602 will move away from each other under the action of their inclined surfaces until the limit holes 510 on the rectangular block 509 contact the two T-shaped plates 602. At this time, the T-shaped plates 602 will slide into the limit holes 510 to complete the preliminary fixation of the rectangular block 509. During the descent of the rectangular block 509, it drives the connecting rod 507 to descend. The connecting rod 507 drives the two isosceles trapezoidal plates 506 to move closer to each other. The isosceles trapezoidal plates 506 slide into the sliding grooves 504. At this time, the isosceles trapezoidal plates 506 do not lock the triangular block 3. Then pull the rectangular block 509 in the direction away from the limit sliding plate 608. The rectangular block 509 drives the limit sliding plate 503 to move. The limit sliding plate 503 drives the hollow fixing frame 501 to move.

8. A method for using a syringe positioning device for animal husbandry and veterinary medicine, using the syringe positioning device for animal husbandry and veterinary medicine as claimed in claim 7, characterized in that: The method steps are as follows: S1: Narrow the space: The hollow fixing frame (501) drives the limit sliding plate (503) to move synchronously. The limit sliding plate (503) drives the isosceles trapezoidal plate (506) to move synchronously. The isosceles trapezoidal plate (506) contacts the triangular block (3), and the isosceles trapezoidal plate (506) compresses the fixing spring (505). At this time, the isosceles trapezoidal plate (506) slides in the sliding groove (504). By analogy, when the rectangular plate (606) stops descending, the isosceles trapezoidal plate (506) will no longer move. At this time, the isosceles trapezoidal plate (506) gets stuck on the corresponding triangular block (3). At this time, the space above the rectangular plate (606) becomes smaller, and the pigs can be effectively controlled and positioned; S2: Clamp the head: The positioning spring (701) drives the U-shaped mounting plate (702) to descend. The U-shaped mounting plate (702) stops moving when it touches the pig's back. At this time, since the limit sliding plate (608) continues to descend, the positioning spring (701) compresses. At this time, the U-shaped mounting plate (702) clings more tightly to the pig's back. The descent of the U-shaped mounting plate (702) drives the adjusting T-shaped screw rod (705) to descend. The adjusting T-shaped screw rod (705) drives the L-shaped hollow plate (706) to descend. The L-shaped hollow plate (706) drives the syringe (707) to descend. When the U-shaped mounting plate (702) stops moving, the syringe (707) is exactly at the pig's neck; S3: Fix the syringe (707): Insert the syringe (707) into the L-shaped hollow plate (706) and insert the needle into the pig's neck. Then rotate the T-shaped fixing screw rod (709). The T-shaped fixing screw rod (709) drives the rubber blocks (708) to move closer to each other to clamp the syringe (707) to ensure that the syringe (707) is stable and does not rotate. Then push in the drug to ensure the stability of the syringe (707) during the injection process; S4: Releasing the livestock: After the injection is completed, the driving motor (804) is started again to separate the two L-shaped clamping plates (803). At this time, the rectangular block (509) is slid downward. The rectangular block (509) will contact the two T-shaped plates (602) during the descent process. The T-shaped plates (602) will move away from each other under the action of their inclined surfaces until the limiting holes (510) on the rectangular block (509) contact the two T-shaped plates (602). At this time, the T-shaped plates (602) will slide into the limiting holes (510) to complete the preliminary fixation of the rectangular block (509). During the descent process of the rectangular block (509), the connecting rod (509) will be driven. 7) descends, the connecting rod (507) drives the two isosceles trapezoidal plates (506) to approach each other, and the isosceles trapezoidal plates (506) slide into the sliding groove (504). At this time, the isosceles trapezoidal plates (506) will not lock the triangular block (3), and then pull the rectangular block (509) in the direction away from the limiting sliding plate (608), and the rectangular block (509) drives the limiting slide plate (503) to move, and the limiting slide plate (503) drives the hollow fixed frame (501) to move. When the limiting slide plate (503) moves to the initial position, the limiting slide plate (503) is pulled out from the hollow fixed frame (501) to release the injected pig.
