Description

Technical Field

[0001] The utility model belongs to the technical field of poultry immunization equipment, in particular to a high-speed syringe. Background Art

[0002] Hatcheries, breeder farms, and poultry farms often conduct large-scale vaccinations. For example, intensive poultry farms perform eight avian influenza vaccinations annually on 50-day-old poultry. Animal vaccinations are often performed in batches, exacerbating the complexities and workload of traditional handheld syringes, as well as the risk of chick mortality from incorrect injections. Automatic injection machines offer a range of advantages for chick vaccination. They utilize a touch or photoelectric switch for automated puncture and dosing, significantly increasing injection speed.

[0003] The existing Chinese utility model patent application number 201820149902.5 discloses a continuous syringe needle assembly, comprising a syringe, a piston rod, a drive device, and a mounting bracket. The syringe is fixed to the mounting bracket, and the piston rod is inserted into the syringe. The drive device includes a power output end and an elastic member located between the power output end and the piston rod. After the power output end compresses the elastic member, the elastic member pushes the piston rod. When the power output end drives the piston rod to reset, the elastic member applies a force to the piston rod in the pushing direction. However, the syringe of the above-mentioned syringe is fixedly mounted on a fixed base. When the power output end drives the piston rod to move, it cannot drive the needle on the syringe to extend or retract, which is not conducive to improving the injection speed of the syringe. Moreover, when the above-mentioned syringe is performing high-speed continuous injection, the operating stability of the connection between the power output end and the piston rod is poor, and there is a delay in the reset of the piston rod, which affects the injection efficiency of the syringe.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] A high-speed syringe, such as Figures 1 to 4As shown, it includes a base 1, a sliding seat 19 provided at one end of the base 1, and a buffer block 10 provided at the other end of the base 1.

A first elastic element 17 is provided on the piston rod 23 at a position corresponding to the limit piece 18 and the syringe 12, and one end of the first elastic element 17 presses against the limit piece 18, and the other end presses against the syringe 12; a second elastic element 21 is provided on the sliding seat 19 at a position corresponding to the limit piece 18, and one end of the second elastic element 21 presses against the sliding seat 19, and the other end presses against the limit piece 18.

[0030] Exemplarily, the syringe body also includes a needle 11, which is mounted on the end of the syringe barrel that is different from the piston rod 23 and extends out of the base 1. A buffer block 10 can be fixed to the base 1 via screws. The provision of the buffer block 10 can provide effective buffering and protection for the moving mounting base 14, thereby improving the reliability of the mounting base 14 and the syringe body during high-speed movement and preventing the syringe body from moving or being damaged due to high-speed collisions.

[0031] In actual use, the stopper 18 and the piston rod 23 are connected by a threaded connection. The sliding seat 19 is provided with a stopper groove 29 that cooperates with the stopper 18. The stopper 18 and the stopper groove 29 engage with each other to achieve a stable connection between the piston rod 23 and the sliding seat 19, making it easier for operators to disassemble and assemble the primary and secondary syringes, and reducing the difficulty of use and maintenance of the device. In addition, those skilled in the art may also select other methods to achieve a stable connection between the sliding seat 19 and the piston rod 23 according to actual needs, which will not be described in detail here.

[0032] Preferably, an adjusting nut 16 that slidably cooperates with the piston rod 23 is provided on the syringe 12 at a position corresponding to the first elastic element 17, and the adjusting nut 16 is threadedly connected to the syringe 12. By threading the adjusting nut 16 to the syringe 12, the operator can adjust the resetting elastic force of the first elastic element 17 by turning the adjusting nut 16 to change the length of the adjusting nut 16 extending from the syringe 12, thereby enabling the first elastic element 17 to better support the limiter 18 and provide a resetting driving force for the piston rod 23, which is conducive to reducing the difficulty of resetting the piston rod 23 during high-speed movement and further improving the operational stability of the connection between the piston rod 23 and the sliding seat 19.

[0033] Preferably, the sliding seat 19 is provided with an assembly hole 27 for accommodating the second elastic element 21, and the sliding seat 19 is provided with a spring cap 22 that cooperates with the second elastic element 21 at one end facing the syringe body, and a rear locking cap 3 that cooperates with the second elastic element 21 at the other end. The rear locking cap 3 is detachably mounted on the sliding seat 19, and one end of the second elastic element 21 supports the spring cap 22, and the other end supports the rear locking cap 3; the spring cap 22 is slidably mounted on the sliding seat 19, and the sliding direction of the spring cap 22 is the same as the sliding direction of the sliding seat 19.

[0034] For example, the rear locking cap 3 is threadedly connected to the sliding seat 19, which not only facilitates replacement and maintenance of the second elastic element 21 by the operator, but also allows the operator to adjust the return force of the second elastic element 21 by screwing the rear locking cap 3. The spring cap 22 has an annular protrusion on one end that extends into the assembly hole 27. The assembly hole 27 can be constructed similar to a countersunk hole to limit the position of the spring cap 22. Those skilled in the art can also choose other methods to install the spring cap 22 according to actual needs to ensure stable sliding of the spring cap 22 on the sliding seat 19. This will not be described in detail here.

[0035] In actual application, both the first elastic element 17 and the second elastic element 21 can be compression springs, and grooves for engaging with the compression springs are provided on the spring cap 22 and the rear lock cap 3. The provision of the grooves helps to improve the stability and reliability of the second elastic element 21 during high-speed movement of the sliding block, thereby increasing the service life of the second elastic element 21.

[0036] Preferably, the drive assembly includes a cylinder 2 provided on the base 1, and the telescopic end of the cylinder 2 is connected to the rear locking cap 3 via a connector 4. Exemplarily, the cylinder 2 can be connected to the air supply system of an existing injection molding machine to realize the action of driving the cylinder 2, which will not be described in detail here. Among them, the fixed end of the cylinder 2 can be fixed to the adjustment seat by screws, one end of the connector 4 is threadedly connected to the telescopic end of the cylinder 2, and the other end is threadedly connected to the rear locking cap 3. Those skilled in the art can also choose other ways to install the connector 4 according to actual needs to achieve a stable connection between the telescopic end of the cylinder 2 and the rear locking cap 3, so that the telescopic end of the cylinder 2 can drive the sliding seat 19 to move stably through the connector 4 and the rear locking cap 3, which will not be described in detail here.

[0037] Preferably, a micro switch 7 for counting is also provided at a position on the base 1 corresponding to one side of the sliding seat 19, and the sliding seat 19 is provided with a toggle member 6 that cooperates with the micro switch 7; the toggle member 6 is installed on the sliding seat 19 by at least two connecting screws, and the toggle member 6 is provided with a long hole 5 that cooperates with the connecting screws; the length direction of the long hole 5 is the same as the moving direction of the sliding seat 19.

[0038] Exemplarily, the micro switch 7 can adopt an existing mechanical switch, and the micro switch 7 can be fixed on the adjustment seat by screws. By using the micro switch 7 in conjunction with the toggle member 6, the movement of the sliding seat 19 here can be detected, thereby determining the number of injections of the main syringe and the auxiliary syringe respectively, which is convenient for the operator to count.

[0039] In actual use, two connecting screws can be provided, and the sliding seat 19 is provided with screw holes that cooperate with the connecting screws. By using at least two connecting screws to install the toggle member 6, the stability of the toggle member 6 on the sliding seat 19 is improved, ensuring that the toggle member 6 can continuously and stably cooperate with the micro switch 7 to achieve counting. In addition, by providing the elongated hole 5 in the toggle member 6, the operator can also adjust the position of the toggle member 6 on the sliding seat 19 according to actual needs, ensuring that the toggle member 6 can better cooperate with the micro switch 7, which is conducive to improving the accuracy of the high-speed syringe counting.

[0040] Preferably, the mounting seat 14 is provided with an assembly groove 25 for accommodating the syringe 12, the syringe 12 is provided with a locking piece 15 at one end facing the sliding seat 19, and a flat portion 26 at the other end, and the mounting seat 14 is provided with a card groove 24 that cooperates with the locking piece 15, and the card groove 24 is connected to the assembly groove 25; the position of the mounting seat 14 corresponding to the flat portion 26 is provided with a pressure strip 13 that cooperates with the flat portion 26, and the pressure strip 13 is detachably mounted on the mounting seat 14.

[0041] For example, the pressure strip 13 can be fixed to the mounting seat 14 by fixing screws. In addition, the locking member 15 and the syringe 12 can be connected by a threaded connection. By installing the pressure strip 13 and the locking member 15 on the syringe 12, the pressure strip 13 can effectively limit the vertical position of the syringe 12, and the locking member 15 can effectively limit the horizontal position of the syringe 12 by engaging with the card slot 24, which is beneficial to improving the stability of the syringe 12 on the main mounting seat 14 or the auxiliary mounting seat 14.

[0042] Preferably, the base 1 is provided with a slide rail 8 that slides with the mounting seat 14 and the sliding seat 19. Exemplarily, the slide rail 8 is provided with a guide groove 9 that slides with the mounting seat 14 and the sliding seat 19, and the left and right sides of the sliding seat 19 are respectively provided with sliders 28. The slide rail 8 is provided with a slide groove 20 that cooperates with the slider 28, and the slide groove 20 is connected to the guide groove 9.

[0043] In actual use, the sliders 28 are fixed to the left and right sides of the sliding seat 19 to form an inverted T-shaped structure. The guide rail groove and its left and right sliding grooves 20 form a T-shaped groove that cooperates with the inverted T-shaped structure. This helps further improve the stability of the mounting seat 14 during the sliding process. By providing the guide grooves 9 on the guide rail, the guide grooves 9 can effectively guide the high-speed moving slider and mounting seat 14, ensuring that the slider can continuously and stably push the piston rod 23 and the syringe 12 on the mounting seat 14 to achieve continuous telescopic injection of the syringe 12.

[0044] Preferably, the slide rail 8 and the buffer block 10 are made of PP material. Compared with other materials, PP material (polypropylene) has better wear resistance and impact resistance, can improve the service life of the slide rail 8, and ensure the stability of the movement of the sliding seat 19 and the mounting seat 14.

[0045] The working principle of this high-speed injector is as follows:

[0046] The telescopic end of the cylinder 2 drives the sliding seat 19 to move. Due to the cushioning effect of the second elastic element 21 on the sliding seat 19 and the first elastic element 17 on the piston rod 23, the instantaneous movement speed of the piston rod 23 is reduced, slowing the speed at which the drug solution is ejected, increasing the poultry's adaptability to the drug and reducing its stress sensitivity. Furthermore, when the telescopic end of the cylinder 2 drives the sliding seat 19 to reset, the force exerted by the second elastic element 21 on the upper limit member 18 of the piston rod 23 does not immediately disappear, maintaining the piston rod 23 in the injection state and effectively reducing residual drug solution in the syringe 12. Simultaneously, the restoring force of the first elastic element 17 acts on the other side of the limit member 18, pushing the limit member 18 to reset the piston rod 23 and syringe 12, which helps to increase the reset speed of the piston rod 23 and syringe 12 and ensure the next movement of the piston rod 23.

[0047] The high-speed syringe described in this utility model has the advantages of fast injection speed and good vaccination effect. By slidably mounting both the mounting seat and the sliding seat on the base, and utilizing the first elastic element and the second elastic element to cooperate, the reset speed of the piston rod and the syringe is improved, ensuring the next piston rod movement. Thus, this syringe can improve the overall injection speed and injection efficiency of the syringe while ensuring the injection effect of the syringe body.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
