Description

Technical Field

[0001] This utility model relates to the technical field of injection, and in particular to an injection device for animal husbandry and veterinary medicine. Background Technology

[0002] Many farms raise poultry and livestock, and if the numbers are large, veterinarians need to administer medication to prevent common diseases. Administering medication requires syringes, but commonly used syringes require both hands to draw the medication, making it difficult to control the precise amount drawn and injected into the animal. They cannot be used with one hand and are inefficient.

[0003] Therefore, those skilled in the art have provided an injection device for animal husbandry and veterinary medicine to solve the problems mentioned. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an injection device for animal husbandry and veterinary medicine.

[0005] The injection device for animal husbandry and veterinary medicine provided by this utility model adopts the following technical solution:

[0006] An injection device for animal husbandry and veterinary medicine includes a syringe with a piston rod inserted inside. A circular plate is fixedly installed at one end of the piston rod. A side plate is fixedly installed on the side of the circular plate. A threaded rod is fixedly installed on one side of the side plate. A second side plate is fixedly installed on the side of the syringe. The threaded rod passes through the second side plate. A limiting plate is fixedly sleeved on the threaded rod. A spring is also sleeved on the threaded rod and is positioned between the second side plate and the limiting plate. A rotating block is also threadedly installed on the threaded rod. The device can be operated with one hand and can also quantitatively draw and inject medication.

[0007] Preferably, a limit block is fixedly installed at the other end of the threaded rod to prevent the rotating block from disengaging from the threaded rod.

[0008] Preferably, two positioning posts are symmetrically fixedly installed on the side of the piston rod, and the two positioning posts are inserted into a limit frame to install the limit frame.

[0009] Preferably, two notches are symmetrically provided on the circular plate, and the limiting frame passes through the two notches to limit the position of the limiting frame. When the thumb is placed on the circular plate, the limiting frame can be moved by the upper surface of the thumb to speed up the absorption of the medicine.

[0010] In summary, this utility model has the following beneficial technical effects:

[0011] 1. Under the action of the spring, the circular plate and piston rod can be moved, and the negative pressure generated in the syringe can draw in the drug liquid. The amount of drug liquid drawn in is fixed and can be adjusted and controlled by the position of the rotating block. After the drug liquid is injected into the animal, the spring is in a compressed state and the drug liquid can be drawn in repeatedly. The force of pulling the piston rod can be converted into the force of pressing the spring. It is convenient to use, easy to use with one hand, and has high efficiency.

[0012] 2. When a large amount of liquid medicine needs to be drawn, the piston rod can be pushed outward with the thumb to speed up the drawing process. The limit bracket can be inserted into the positioning column for easy disassembly and assembly. It can be installed as needed. The notch can limit the limit bracket to prevent it from rotating.

[0016] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0017] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown in the drawings have been exaggerated or reduced in size; any dimensions are merely exemplary and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0018] This utility model discloses an injection device for animal husbandry and veterinary medicine.

[0019] An injection device for animal husbandry and veterinary medicine includes a syringe 1, a piston rod 11 inserted into the syringe 1, a circular plate 12 fixedly installed at one end of the piston rod 11, a side plate 13 fixedly installed on the side of the circular plate 12, a threaded rod 18 fixedly installed on one side of the side plate 13, a second side plate 14 fixedly installed on the side of the syringe 1, the threaded rod 18 passing through the second side plate 14, a limiting plate 15 fixedly sleeved on the threaded rod 18, and a spring 16 sleeved on the threaded rod 18, the spring 16 being disposed between the second side plate 14 and the limiting plate 15. A rotating block 17 is also threadedly installed on the threaded rod 18, allowing for single-handed operation and quantitative aspiration and injection of medication.

[0020] A limit block 19 is fixedly installed at the other end of the threaded rod 18 to prevent the rotating block 17 from disengaging from the threaded rod 18.

[0021] Two positioning posts 2 are symmetrically fixedly installed on the side of the piston rod 11. The two positioning posts 2 are inserted into the limit frame 21, which can be installed on the limit frame 21. Two notches 22 are symmetrically opened on the circular plate 12. The limit frame 21 passes through the two notches 22, which can limit the limit frame 21. When the thumb is placed on the circular plate 12, the limit frame 21 can be moved by the upper surface of the thumb to speed up the absorption of the medicine.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The implementation principle of the injection device for animal husbandry and veterinary medicine in this embodiment is as follows: A needle can be installed at the mouth of the syringe 1. Rotating the rotating block 17 can limit the threaded rod 18. Under the action of the spring 16, the circular plate 12 and the piston rod 11 can be moved. The negative pressure generated in the syringe 1 can draw in the medicine, and the amount drawn in is fixed and can be adjusted and controlled by the position of the rotating block 17. After the medicine is injected into the animal, the spring 16 is in a compressed state, and the medicine can be drawn in repeatedly. The force of pulling the piston rod 11 can be converted into the force of pressing the spring 16, which is convenient to use and easy to use with one hand. When a large amount of medicine needs to be drawn in, the thumb can be placed in the limiting frame 21. The piston rod 11 can be pushed outward by the thumb, which can speed up the drawing speed and make up for the lack of elasticity of the spring 16. The limiting frame 21 can be inserted into the positioning post 2 for easy disassembly and assembly. It can be installed selectively as needed. The notch 22 can limit the limiting frame 21 to prevent the limiting frame 21 from rotating.
