Description

Technical Field

[0001] The present invention relates to a detection device, specifically a veterinary livestock disease detection device. Background Art

[0002] A veterinary livestock disease detection device is a device used to detect and diagnose various diseases that livestock may be infected with, and is used to collect and detect whether there are pathogens (such as viruses, bacteria, parasites, etc.) of certain infectious diseases in the animal body. These detection devices are widely used in the livestock industry, animal farms, and veterinary clinics to improve the efficiency of livestock health management and ensure the safety of meat and dairy products.

[0003] Currently, the general veterinary livestock disease detection devices generally include two methods of collecting and detecting body fluids, namely pharyngeal swab collection and anal swab collection. Among them, anal swab collection has the least impact on livestock and lower costs. Chinese Patent Application (Application No. 202410050417.2) discloses a veterinary livestock disease detection device, including a handle, on which an electrical button is provided. The handle is connected to a mounting post, on which a mating post is rotatably mounted. The end of the mating post is circumferentially and evenly provided with chucks, and a sampling cotton swab is clamped between the chucks. It is characterized in that a raised strip is provided on the mating post, a gear disk is slidably mounted on the mating post, a pushing mechanism and a rotary driving mechanism are provided between the gear disk and the mounting post, rigid pushing rods are evenly provided on the gear disk, and a clamping assembly is provided between the rigid pushing rods and the chucks. The gear disk moves back and forth along the mating post under the drive of the pushing mechanism, driving the clamping assembly to make the chucks approach or separate from each other, realizing the clamping and loosening of the sampling cotton swab. The rotary driving mechanism drives the gear disk and the mating post to rotate, and then drives the sampling cotton swab between the chucks to rotate for sampling, solving the problem that the existing anal swab collection mainly uses a cotton swab collected manually, with low collection efficiency and easy contamination of the hands, which may cause cross-infection. However, the automatic loading and unloading of the cotton swab cannot be achieved during collection, and the veterinarian still needs to manually load the cotton swab, which will also cause the hands to come into contact with the collection end, resulting in cross-infection. Summary of the Invention

[0016] The other end of the screw rod is fixedly connected to a first gear, the first gear meshes with a second gear, and the second gear is fixedly connected to one end of a rhombic transmission shaft. The rhombic transmission shaft is rotatably connected in the cavity of the fuselage main body.

[0017] The veterinary livestock disease detection device as described above: One side of the moving seat is fixedly connected with a second U-shaped frame. Inside the cavity of the fuselage main body at the horizontal position on one side of the second U-shaped frame, a first U-shaped frame is installed. The first U-shaped frame and the second U-shaped frame are in contact with the collection cotton swab;

[0018] On the moving seat, a threaded hole, a sliding hole, and a rotating groove are sequentially arranged from bottom to top. The threaded hole is in threaded connection with a screw rod, and the sliding hole is in sliding connection with a rhombic transmission shaft.

[0019] The veterinary livestock disease detection device as described above: The linkage mechanism includes an overload protection component arranged at the position of the sliding hole opened on the moving seat, a toothed ring connected to the overload protection component, and a rotating seat fixedly connected to the inner wall of the toothed ring;

[0020] The overload protection component includes a third gear meshing with the toothed ring and an overload cylinder rotatably connected inside the third gear. A rotating ring is opened on the inner wall of the third gear, and a plurality of engaging grooves are annularly opened on the inner wall of the third gear at the position of the rotating ring.

[0021] The veterinary livestock disease detection device as described above: A plurality of springs are annularly arranged on the overload cylinder.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] By setting a self-loading and unloading collection structure inside the fuselage main body, it is possible to achieve self-loading and unloading clamping of the collection cotton swab. By setting a feeding mechanism at the top of the fuselage main body, the feeding mechanism can control the collection cotton swabs to fall one by one into the fuselage main body. Then, under the clamping of the self-loading and unloading collection structure, one end of the collection cotton swab can be clamped. Driven by the self-loading and unloading collection structure, the collection cotton swab can extend out of the fuselage main body. During the extension process, the self-loading and unloading collection structure can drive the collection cotton swab to rotate, which is convenient for making the collection cotton swab adhere to a sufficient amount of livestock body fluid when collecting livestock anal swabs, facilitating later detection and use. After the collection is completed, by pulling the fuselage main body, the collection cotton swab is drawn out of the livestock body, and then through the reset of the self-loading and unloading collection structure, the collection cotton swab can fall off automatically, avoiding the operator from taking and loading and unloading the collection cotton swab, resulting in hygienic infection, improving hygienic safety. Through the design, it can prevent veterinarians from touching the end of the fuselage main body when disassembling and assembling the cotton swab, causing hand contamination, and can improve the collection efficiency during disease detection.

Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0045] Please refer to Figures 1 to 15 , in the embodiments of the present invention, a livestock disease detection device for veterinarians includes the main body of the fuselage 1 and a grip 3 fixed to the main body of the fuselage 1. A self-loading and unloading collection structure is arranged in the cavity of the main body of the fuselage 1, and a collection cotton swab 13 is clamped on the self-loading and unloading collection structure;

[0046] The self-loading and collecting structure includes a driving mechanism installed in the cavity of the fuselage main body 1, a moving seat 16 connected to the driving mechanism, a linkage mechanism installed on the moving seat 16 and connected to the driving mechanism, and a clamping mechanism installed on the linkage mechanism. The clamping mechanism clamps one end of the collecting cotton swab 13.

[0047] When the driving mechanism operates, it is used to make the moving seat 16 move horizontally in the cavity of the fuselage main body 1. During the horizontal movement of the moving seat 16, the linkage mechanism is driven to act synchronously. The linkage mechanism transmits a part of the power of the driving mechanism to the clamping mechanism to make it rotate on the linkage mechanism. The clamping mechanism acts to clamp the collecting cotton swab 13, so that the collecting cotton swab 13 moves with the moving seat 16 and rotates synchronously under the drive of the clamping mechanism.

[0048] In this embodiment, one end of the collecting cotton swab 13 is clamped by the self-loading and collecting structure. Driven by the self-loading and collecting structure, the collecting cotton swab 13 extends outwards from the cavity of the fuselage main body 1. Driven by the driving mechanism, the moving seat 16 moves horizontally in the cavity of the fuselage main body 1. A linkage mechanism and a clamping mechanism are installed on the moving seat 16. The clamping mechanism clamps one end of the collecting cotton swab 13. Therefore, during the movement of the moving seat 16, the linkage mechanism and the clamping mechanism will move synchronously. At the same time, the collecting cotton swab 13 will move synchronously with the moving seat 16. Through the transmission of the linkage mechanism, a part of the power of the driving mechanism can be transmitted to the clamping mechanism, enabling the clamping mechanism to adjust the clamping and loosening. When the moving seat 16 moves the collecting cotton swab 13 outwards from the cavity of the fuselage main body 1, the clamping mechanism can clamp one end of the collecting cotton swab 13, so that when the other end of the collecting cotton swab 13 extends out of the cavity of the fuselage main body 1, it can be kept clamped and fixed. When the moving seat 16 moves in the reset direction, the clamping mechanism can loosen the clamped end of the collecting cotton swab 13, causing the collecting cotton swab 13 to fall off, which is used to separate the collecting cotton swab 13 after collection, improving the convenience and efficiency of collection.

[0049] As a further solution of the present invention, a charging hole 2 is provided at one end of the fuselage main body 1, and scale observation windows 6 are provided on both sides of the fuselage main body 1.

[0050] A control switch 4 is provided on the grip 3, and a steering adjustment dial 5 is provided on the grip 3 above the control switch 4.

[0051] A falling hole 12 is provided at the top of the fuselage main body 1, and a feeding mechanism is installed on the fuselage main body 1 at the position of the falling hole 12.

[0052] In this embodiment, a power supply component is provided at the position of the grip 3 on the fuselage main body 1 to meet the energy supply and use of the fuselage main body 1. The charging hole 2 provided on the fuselage main body 1 is used to charge the power supply component to achieve the effect of recycling. Through the scale observation window 6 provided on the fuselage main body 1, the extended length of the collection swab 13 can be observed and compared to meet the accurate collection use effect. Through the control switch 4 provided on the grip 3, the movement of the self-loading and unloading collection structure can be controlled. Through the adjustment of the steering adjustment dial 5, the movement direction of the self-loading and unloading collection structure can be controlled to meet the adjustment use requirements.

[0053] As a further solution of the present invention, the feeding mechanism includes a storage bin 7 installed on the fuselage main body 1 and a rotating cylinder 10 slidably inserted inside the storage bin 7. A plurality of fitting groove holes adapted to the collection swab 13 are annularly arrayed on the rotating cylinder 10;

[0054] One end of the rotating cylinder 10 is fixedly connected to a knob 9 through a fixed shaft. A threaded cover 8 is rotatably connected to the fixed shaft between the knob 9 and the rotating cylinder 10, and the threaded cover 8 is threadedly connected to one end of the storage bin 7;

[0055] A dropping frame 11 is provided at the bottom of the storage bin 7, and the dropping frame 11 is communicated with the dropping hole 12.

[0056] In this embodiment, through the design of the feeding mechanism, after the previous collection swab 13 is collected and separated, by rotating the knob 9, the fitting groove hole for placing the collection swab 13 opened on the rotating cylinder 10 can be rotated to the position of the dropping frame 11. Since the dropping frame 11 is communicated with the dropping hole 12, the collection swab 13 will drop into the cavity of the fuselage main body 1 to meet the feeding use requirements and improve the replacement efficiency of the collection swab 13 by veterinarians during collection, thereby further improving the collection efficiency.

[0057] As a further solution of the present invention, the driving mechanism includes a screw rod 17 rotatably connected in the cavity of the fuselage main body 1 and a micro motor 18 whose output shaft is coaxially fixed to one end of the screw rod 17. The micro motor 18 is installed in the cavity of the fuselage main body 1;

[0058] The other end of the screw rod 17 is fixedly connected to a first gear 19. The first gear 19 meshes with a second gear 20. The second gear 20 is fixedly connected to one end of a rhombic transmission shaft 21, and the rhombic transmission shaft 21 is rotatably connected in the cavity of the fuselage main body 1.

[0059] In this embodiment, by the rotation of the micro motor 18, the screw 17 can be rotated within the cavity of the fuselage main body 1. Since one end of the screw 17 can drive the rhombus transmission shaft 21 through the meshing of the first gear 19 and the second gear 20, the rhombus transmission shaft 21 can rotate synchronously with the screw 17 to meet the driving use requirements, enabling the components on the rhombus transmission shaft 21 to operate under the drive of the micro motor 18.

[0060] As a further solution of the present invention, a second U-shaped frame 15 is fixedly connected to one side of the moving seat 16. A first U-shaped frame 14 is installed in the cavity of the fuselage main body 1 at the horizontal position on one side of the second U-shaped frame 15. The first U-shaped frame 14 and the second U-shaped frame 15 are arranged in contact with the collection cotton swab 13.

[0061] Threaded holes 22, sliding holes 23 and rotating grooves 24 are sequentially arranged on the moving seat 16 from bottom to top. The threaded holes 22 are threadedly connected with the screw 17, and the sliding holes 23 are slidably connected with the rhombus transmission shaft 21.

[0062] In this embodiment, the threaded holes 22 provided on the moving seat 16 are threadedly connected with the screw 17, and the sliding holes 23 opened on the moving seat 16 are slidably connected with the rhombus transmission shaft 21. Therefore, when the screw 17 rotates, the moving seat 16 is limited by the sliding holes 23 and the rhombus transmission shaft 21 and cannot rotate. Therefore, when the screw 17 rotates, it can drive the moving seat 16 to be horizontally adjusted within the cavity of the fuselage main body 1 to meet the driving requirements. When the moving seat 16 is slidably adjusted, since the diameter of the sliding holes 23 opened on the moving seat 16 is larger than that of the rhombus transmission shaft 21, when the rhombus transmission shaft 21 rotates synchronously with the screw 17, the rhombus transmission shaft 21 can smoothly rotate inside the sliding holes 23 without hindering the rotation use of the rhombus transmission shaft 21, ensuring the adjustment use effect of the moving seat 16.

[0063] As a further solution of the present invention, the linkage mechanism includes an overload protection component arranged at the position of the sliding holes 23 opened on the moving seat 16, a toothed ring 26 connected to the overload protection component, and a rotating seat 25 fixedly connected to the inner wall of the toothed ring 26.

[0064] The overload protection component includes a third gear 27 meshing with the toothed ring 26 and an overload cylinder 28 rotatably connected inside the third gear 27. A rotating ring 29 is opened on the inner wall of the third gear 27, and a plurality of engaging grooves 30 are annularly opened on the inner wall of the third gear 27 at the position of the rotating ring 29.

[0065] A plurality of springs 31 are arranged in an annular array on the overload cylinder 28. One end of each spring 31 is fixedly connected to the overload cylinder 28, and the other end of each spring 31 is fixedly connected to a clamping ball head 32. The clamping ball head 32 is slidably connected within the rotating ring 29, and the clamping ball head 32 is correspondingly fitted into the clamping groove 30. Both the rotating seat 25 and the toothed ring 26 are rotatably connected within the rotating groove 24. A slot hole corresponding to the rhombic transmission shaft 21 is formed in the overload cylinder 28 for slidingly sleeving.

[0066] In this embodiment, a slot hole corresponding to the rhombic transmission shaft 21 is formed in the overload cylinder 28. Therefore, when the rhombic transmission shaft 21 rotates, it can drive the overload cylinder 28 to rotate. Also, since the overload cylinder 28 is sleeved on the rhombic transmission shaft 21, when the moving seat 16 is horizontally adjusted and moved, the overload cylinder 28 can move synchronously with the moving seat 16 without interfering with the rotational driving requirement of the rhombic transmission shaft 21 for the overload cylinder 28. The overload cylinder 28 rotates on the inner wall of the third gear 27. The clamping ball head 32 provided on the overload cylinder 28 is fitted into the clamping groove 30. When the overload cylinder 28 rotates, it can drive the third gear 27 to rotate synchronously. The third gear 27 meshes with the toothed ring 26, so that the rotating seat 25 fixed to the inner wall of the toothed ring 26 rotates on the moving seat 16. During overload, the clamping ball head 32 will abut against the clamping groove 30, thereby forcing the clamping ball head 32 to abut against the spring 31, causing the spring 31 to be compressed and contracted within the slot hole on the outer wall of the overload cylinder 28 and maintaining a resilient force. At this time, the clamping ball head 32 disengages from the engagement with the clamping groove 30, and the clamping ball head 32 will slide within the rotating ring 29. The rhombic transmission shaft 21 drives the overload cylinder 28 to rotate on the inner wall of the third gear 27, and the third gear 27 does not follow the overload cylinder 28 to rotate, thus achieving overload protection, improving the transmission use effect, and meeting the clamping use of the collection cotton swab 13. When the overload force disappears, the spring 31 rebounds, causing the clamping ball head 32 to be engaged in the clamping groove 30 again, so that when the overload cylinder 28 rotates, it can drive the third gear 27 to rotate followingly again.

[0067] As a further solution of the present invention, the clamping mechanism includes a fixed ring 33 fixedly connected to the moving seat 16, a plurality of clamping plates 34 arranged in an annular array and abutting against one side of the fixed ring 33, and a positioning ring 35 abutting against one side of the plurality of clamping plates 34;

[0068] A sliding groove 36 is formed on one side of the fixed ring 33 close to the clamping plates 34. A sliding block 37 is fixedly provided at the corner of one side of the clamping plate 34, and a connecting column 38 is fixedly provided at the center of the edge of the other side of the clamping plate 34. A plurality of adjusting grooves 39 are formed in an annular array on the positioning ring 35;

[0069] The sliding blocks 37 on one side of the clamping plates 34 are slidably connected in the corresponding sliding grooves 36 , the connecting columns 38 on the other side of the clamping plates 34 are slidably connected in the corresponding adjustment grooves 39 , and the positioning ring 35 is fixedly connected to one end of the rotating seat 25 .

[0070] In this embodiment, the clamping mechanism of this scheme is the same as the mechanical iris mechanism in the prior art, and no further details will be given here. The outer wall of the fixing ring 33 is fixedly connected to the movable seat 16, and the positioning ring 35 is fixedly connected to one end of the rotating seat 25. When the rotating seat 25 rotates, the movable seat 16 remains stationary, so the rotation of the rotating seat 25 causes the positioning ring 35 to rotate accordingly. When the positioning ring 35 rotates to cause the multiple clamping plates 34 to close and clamp one end of the collection cotton swab 13, it is in an overload state at this time. Through the design of the overload protection component, the positioning ring 35 can be kept in a tightly clamped state without the problem of loosening. When the feeding mechanism unloads the collection cotton swabs 13 one by one, the collection cotton swabs 13 will fall on the first U-shaped frame 14 and the second U-shaped frame 15. Since the U-shaped bottom of the second U-shaped frame 15 is flush with the center of the multiple clamping plates 34, the bottom of the first U-shaped frame 14 is provided with a corresponding groove for one end of the collection cotton swab 13 to be embedded The U-shaped frame 14 is provided with a plurality of clamping plates 34 for holding the cotton swab 13. The clamping plates 34 are provided on the first U-shaped frame 14 to hold the cotton swab 13 in place.

[0071] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
