Description

Technical Field

[0001] The utility model relates to the technical field of drug injection pumps, in particular to a high-precision animal drug injection pump. Background Technique

[0002] The veterinary drug injection pump is a pump instrument designed specifically for animal medical treatment. It can accurately, microscopically, evenly, and continuously pump a small amount of liquid medicine into the animal body, so that the medicine maintains an effective blood drug concentration in the body. The structure of the veterinary drug injection pump usually includes a stepper motor and its driver, a lead screw and a nut, a syringe, and a control system. At present, veterinary drug injection pumps are divided into split injection pumps and integrated injection pumps.

[0003] When the split veterinary drug injection pump is in use, due to the split design between its main unit and the injection part, it has the advantage of being easy to store and has better portability. However, the split veterinary drug injection pump also has the following problems when in use. Specifically, when the injection part is in use, it is necessary to inject the medicine into the animal body through a syringe. However, due to the independent design of the injection part, the stability of the injection part itself is poor during the injection process, which will affect the injection accuracy. In view of this, we propose a high-precision animal drug injection pump. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related technologies to some extent. For this reason, an object of the utility model is to propose a high-precision animal drug injection pump, which improves the accuracy of the injection pump when injecting and treating animals by installing the split injection part on the top of the main unit.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A high-precision animal drug injection pump includes a main unit. A wire is provided at the rear side of the main unit, and a fixed seat is fixed on the top of the main unit. Fixing grooves are opened at both ends of the fixed seat.

[0007] A detachable split injection part is provided on the top of the main unit. The split injection part includes a mounting seat. A connecting groove is opened at the bottom of the mounting seat, and the fixed seat is inserted into the connecting groove and is detachably connected to the connecting groove. Strip-shaped grooves are opened on both sides of the connecting groove. An installation cavity is opened above the strip-shaped groove at the rear side, and a motor is installed in the installation cavity. A groove is opened on the top of the mounting seat, and a lead screw is rotatably installed in the groove. The output shaft of the motor is coaxially key-connected to the lead screw. A push plate that can move horizontally is threadedly connected to the lead screw, and a placement groove is opened on the front end surface of the push plate.

[0008] At both ends of the top of the mounting base, two connecting seats are fixed. At the top of the front connecting seat, a first clamping seat is fixed. At the top edge of the first clamping seat, an adjusting threaded rod is rotatably installed. A second clamping seat that can be lifted is threadedly connected to the adjusting threaded rod. A syringe is clamped between the first clamping seat and the second clamping seat, and the piston rod of the syringe is inserted into the placement groove.

[0009] In addition, the high-precision animal drug injection pump proposed according to the above application may also have the following additional technical features:

[0010] Specifically, two connecting rods are fixed in the strip-shaped grooves. A slider is slidably installed between the two connecting rods. Springs for pressing against the slider are sleeved on the connecting rods; on one side wall of the slider close to the fixed seat, fixed blocks are fixed, and the fixed blocks are inserted and matched with the corresponding fixed grooves.

[0011] Specifically, on the side wall of the slider facing away from the fixed seat, an L-shaped pulling plate is fixed, and the end of the pulling plate passes through the outer wall of the mounting base.

[0012] Specifically, a plurality of heat dissipation grooves are opened at the rear ends of both side walls of the mounting base, and the heat dissipation grooves communicate with the mounting cavity.

[0013] Specifically, on the two opposite end faces of the first clamping seat and the second clamping seat, clamping grooves are opened, and the clamping grooves are arc-shaped.

[0014] Specifically, two guide rods are fixed between the two connecting seats. The guide rods pass through the push plate and are slidably connected to the push plate, and the guide rods are fixed to the connecting seats by bolts.

[0015] Specifically, the cross-sectional shape of the fixed seat is rectangular, and the size of the fixed seat is adapted to the size of the connecting groove.

[0016] Specifically, the slider and the fixed block are of an integrally formed structure, and the size of the slider is adapted to the size of the strip-shaped groove.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] The split injection part can be installed on the top of the main body under the mutual cooperation of structures such as the fixed seat and the fixed block. When injecting and treating animals, the split injection part installed on the top of the main body has better stability, thereby improving the accuracy of the injection pump when injecting and treating animals; when the split injection part is not in use, the split injection part can be directly and quickly disassembled from the top of the main body, which is conducive to separately storing structures such as the main body and the split injection part, and improves the portability of the device.

The split injection part 2 includes a mounting seat 20. A connecting groove 201 is formed at the bottom of the mounting seat 20, and the fixing seat 11 is inserted into the connecting groove 201 and is detachably connected to the connecting groove 201; Strip-shaped grooves 200 are formed on both sides of the connecting groove 201; An installation cavity 202 is formed above the strip-shaped groove 200 at the rear side, and a motor 24 is installed in the installation cavity 202; A groove 204 is formed on the top of the mounting seat 20, and a lead screw 23 is rotatably installed in the groove 204, and the output shaft of the motor 24 is coaxially key-connected to the lead screw 23; A push plate 25 that can move horizontally is threadedly connected to the lead screw 23, and a placement groove 250 is formed on the front end face of the push plate 25; Two connecting seats 21 are fixed at both ends on the top of the mounting seat 20. A first clamping seat 210 is fixed on the top of the front connecting seat 21. An adjusting screw rod 211 is rotatably installed at the top edge of the first clamping seat 210. A second clamping seat 212 that can move up and down is threadedly connected to the adjusting screw rod 211. A syringe 26 is clamped between the first clamping seat 210 and the second clamping seat 212, and the piston handle of the syringe 26 is inserted into the placement groove 250. Two connecting rods 28 are fixed in the strip-shaped grooves 200, and a slider 27 is slidably installed between the two connecting rods 28. Springs 29 for pressing against the slider 27 are sleeved on the connecting rods 28; Fixing blocks 270 are fixed on one side wall of the slider 27 close to the fixing seat 11, and the fixing blocks 270 are inserted and matched with the corresponding fixing grooves 110. Through the insertion and matching of the fixing blocks 270 and the fixing grooves 110, the fixing seat 11 and the mounting seat 20 can be connected and fixed, thus ensuring the connection stability between the split injection part 2 and the main unit 1.

[0031] In this embodiment, an L-shaped pulling plate 271 is fixed on the side wall of the slider 27 facing away from the fixing seat 11, and the end of the L-shaped pulling plate 271 passes through the outer wall of the mounting seat 20. The L-shaped pulling plate 271 facilitates pulling the slider 27 to move, and this design improves the convenience of operation.

[0032] In this embodiment, a plurality of heat dissipation grooves 203 are formed at the rear ends of both side walls of the mounting seat 20, and the heat dissipation grooves 203 communicate with the installation cavity 202. The arrangement of the heat dissipation grooves 203 is beneficial to the heat dissipation of the installation cavity 202 and ensures the stable operation of the motor 24.

[0033] In this embodiment, clamping grooves are formed on the two opposite end faces of the first clamping seat 210 and the second clamping seat 212, and the clamping grooves are arc-shaped. The arc-shaped clamping grooves facilitate clamping and fixing syringes of different sizes.

[0034] In this embodiment, two guide rods 22 are fixed between the two connecting seats 21. The guide rods 22 pass through the push plate 25 and are slidably connected to the push plate 25, and the guide rods 22 are fixed to the connecting seats 21 by bolts. The arrangement of the guide rods 22 increases the stability and smoothness of the horizontal movement of the push plate 25.

[0035] In this embodiment, the cross-sectional shape of the fixed seat 11 is rectangular, and the size of the fixed seat 11 is adapted to the size of the connecting groove 201.

[0037] It can be understood that the main body 1 and the fixed seat 11 are fixedly connected by bolts. The bolt fixation method ensures the firm connection between the fixed seat 11 and the main body 1. At the same time, the bolt connection method also has the advantage of being easy to disassemble and assemble.

[0038] It should be added that the wire 10 in this embodiment is electrically connected to structures such as the motor 24, which is an existing conventional technology and will not be elaborated here.

[0039] During specific use, the user first inserts the connecting groove 201 into alignment with the fixed seat 11. At the same time, the user pulls the pull plates 271 to both sides. The pull plates 271 drive the slider 27 to move horizontally along the two connecting rods 28, and the spring 29 is simultaneously compressed by the slider 27. At this time, the slider 27 drives the fixed block 270 to disengage from the connecting groove 201, and at the same time, the fixed seat 11 is inserted into the connecting groove 201. Subsequently, the user releases the pull plates 271 on both sides. Under the elastic action of the spring 29, the slider 27 moves along the two connecting rods 28, and at the same time, the slider 27 drives the fixed block 270 to insert into the fixing groove 110. Under the restriction of the fixed block 270, the fixed seat 11 is fixed to the connecting groove 201, and the split injection part 2 is fixed to the main body 1.
