Description

Technical Field

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

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

[0003] Current veterinary livestock disease detection devices generally include two methods of body fluid collection and detection: pharyngeal swab collection and anal swab collection. Anal swab collection has the least impact on livestock and has lower costs. A Chinese patent (application number 202410050417.2) discloses a veterinary livestock disease detection device, including a handle, an electrical button is provided on the handle, the handle is connected to a mounting column, a matching column is rotatably installed on the mounting column, and chucks are evenly installed on the ends of the matching column in a circumferential direction, and a sampling cotton swab is clamped and installed between the chucks. The device is characterized in that a raised strip is provided on the matching column, and a gear plate is slidably installed on the matching column. A pushing mechanism and a rotary driving mechanism are arranged between the gear plate and the mounting column, rigid pushing rods are evenly arranged on the gear plate, and a clamping assembly is arranged between the rigid pushing rod and the chuck. The gear plate moves back and forth along the matching column driven by the pushing mechanism, driving the clamping assembly to make the chucks move closer or separate from each other, thereby clamping and releasing the sampling cotton swab. The rotary driving mechanism drives the gear plate and the matching column to rotate, thereby driving the sampling cotton swab between the chucks to rotate and sample, solving the problem that the existing anal swab collection is mainly done manually using cotton swabs, which has low collection efficiency and is easy to contaminate the hands, and may cause cross infection. However, the use effect of automatic loading and unloading of cotton swabs cannot be achieved during collection, and the veterinarian still needs to manually load the cotton swab, which will also cause the hand to contact the collection end, causing cross infection.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] See also Figure 1 to Figure 15 In an embodiment of the present invention, a veterinary livestock disease detection device includes a body 1 and a handle 3 fixed to the body 1, a self-loading and unloading collection structure is provided in the cavity of the body 1, and a collection cotton swab 13 is clamped on the self-loading and unloading collection structure; The self-loading and unloading collection structure includes a driving mechanism installed in the cavity of the 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, wherein the clamping mechanism clamps one end of the collection cotton swab 13; When the driving mechanism is actuated, 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, it drives the linkage mechanism to move 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 is used to clamp the collection cotton swab 13, so that the collection cotton swab 13 moves with the moving seat 16 and rotates synchronously driven by the clamping mechanism.

[0033] In this embodiment, one end of the collection cotton swab 13 is clamped by the self-loading and unloading collection structure. Under the drive of the self-loading and unloading collection structure, the collection cotton swab 13 is extended outward from the cavity of the fuselage main body 1. The driving mechanism drives the movable seat 16 to move horizontally in the cavity of the fuselage main body 1. The movable seat 16 is equipped with a linkage mechanism and a clamping mechanism. The clamping mechanism clamps one end of the collection cotton swab 13. Therefore, during the movement of the movable seat 16, the linkage mechanism and the clamping mechanism will move synchronously. At the same time, the collection cotton swab 13 will move synchronously with the movable seat 16. Through the transmission of the linkage mechanism, the driving mechanism can be A part of the power is transmitted to the clamping mechanism, so that the clamping mechanism can clamp and loosen and adjust. When the moving seat 16 makes the collection cotton swab 13 move outward from the cavity of the fuselage main body 1, the clamping mechanism can clamp one end of the collection cotton swab 13, so that when the collection cotton swab 13 is extended out of the cavity of the fuselage main body 1, the other end can remain clamped and fixed. When the moving seat 16 resets, the clamping mechanism can loosen the clamped end of the collection cotton swab 13, so that the collection cotton swab 13 falls off by itself, which is used to detach the collection cotton swab 13 for use after the collection is completed, thereby improving the convenience of collection and use and improving the collection efficiency.

[0034] As a further solution of the present invention, a charging port 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; A control switch 4 is provided on the handle 3, and a steering adjustment paddle 5 is provided on the handle 3 above the control switch 4; A drop hole 12 is provided on the top of the fuselage main body 1 , and a feeding mechanism is installed on the fuselage main body 1 at the location of the drop hole 12 .

[0035] In this embodiment, a power supply assembly is provided on the body 1 at the position of the handle 3 to meet the energy supply needs of the body 1. The charging hole 2 provided on the body 1 is used to charge the power supply assembly to meet the recycling effect. Through the scale observation window 6 provided on the body 1, the extended length of the collection cotton swab 13 can be compared and observed to meet the precise collection effect. Through the control switch 4 provided on the handle 3, the movement of the self-loading and unloading collection structure can be controlled. By adjusting the steering adjustment paddle 5, the movement direction of the self-loading and unloading collection structure can be controlled to meet the adjustment needs.

[0036] As a further solution of the present invention, the feeding mechanism includes a storage bin 7 mounted on the body 1 and a rotating cylinder 10 slidably inserted into the storage bin 7, and a plurality of fitting slots adapted to the collection cotton swabs 13 are provided in an annular array on the rotating cylinder 10; One end of the rotating cylinder 10 is fixedly connected to a knob 9 via 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; A drop frame 11 is disposed at the bottom of the storage bin 7 , and the drop frame 11 is connected to the drop hole 12 .

[0037] In this embodiment, through the design of the feeding mechanism, after the previous collection cotton swab 13 is collected and detached, the knob 9 can be turned to make the engaging slot hole for placing the collection cotton swab 13 on the rotating cylinder 10 rotate to the position of the drop frame 11. Since the drop frame 11 and the drop hole 12 are connected, the collection cotton swab 13 will fall into the cavity of the main body 1, meeting the feeding and use requirements, improving the efficiency of the veterinarian in replacing the collection cotton swab 13 during collection, and thus being able to further improve the collection efficiency.

[0038] As a further solution of the present invention, the driving mechanism includes a screw 17 rotatably connected to 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 17, and the micro motor 18 is installed in the cavity of the fuselage main body 1; The other end of the screw rod 17 is fixedly connected to a first gear 19 , which meshes with a second gear 20 . The second gear 20 is fixedly connected to one end of a prismatic transmission shaft 21 , and the prismatic transmission shaft 21 is rotatably connected in the cavity of the fuselage body 1 .

[0039] In this embodiment, the screw 17 can be rotated in the cavity of the main body 1 by the rotation of the micro motor 18. Since one end of the screw 17 can drive the prismatic transmission shaft 21 through the engagement of the first gear 19 and the second gear 20, the prismatic transmission shaft 21 can rotate synchronously with the screw 17, meeting the driving requirements, so that the components on the prismatic transmission shaft 21 can operate under the drive of the micro motor 18.

[0040] As a further solution of the present invention, a second U-shaped frame 15 is fixedly connected to one side of the movable seat 16, a first U-shaped frame 14 is installed in the cavity of the fuselage main body 1 at a horizontal position on one side of the second U-shaped frame 15, and the first U-shaped frame 14 and the second U-shaped frame 15 are arranged to conflict with the collection cotton swab 13; The movable seat 16 is provided with a threaded hole 22 , a sliding hole 23 and a rotation groove 24 in sequence from bottom to top. The threaded hole 22 is threadedly connected to the screw rod 17 , and the sliding hole 23 is slidably connected to the prismatic transmission shaft 21 .

[0041] In this embodiment, the threaded hole 22 provided on the moving seat 16 is threadedly connected to the screw rod 17, and the sliding hole 23 provided on the moving seat 16 is slidably connected to the prismatic transmission shaft 21. Therefore, when the screw rod 17 rotates, the moving seat 16 is limited by the sliding hole 23 and the prismatic transmission shaft 21 and cannot rotate. Therefore, when the screw rod 17 rotates, the moving seat 16 can be driven to adjust horizontally in the cavity of the fuselage main body 1 to meet the driving requirements. When the moving seat 16 slides and adjusts, since the diameter of the sliding hole 23 provided on the moving seat 16 is larger than the prismatic transmission shaft 21, when the prismatic transmission shaft 21 rotates synchronously with the screw rod 17, the prismatic transmission shaft 21 can rotate smoothly inside the sliding hole 23, without hindering the rotation of the prismatic transmission shaft 21, thereby ensuring the adjustment effect of the moving seat 16.

[0042] As a further solution of the present invention, the linkage mechanism includes an overload protection component disposed at the sliding hole 23 opened on the movable seat 16, a gear ring 26 connected to the overload protection component, and a rotating seat 25 fixedly connected to the inner wall of the gear ring 26; The overload protection assembly includes a third gear 27 meshing with the gear ring 26 and an overload cylinder 28 rotatably connected to the third gear 27. A rotating ring 29 is provided on the inner wall of the third gear 27. A plurality of engaging grooves 30 are provided in an annular manner on the inner wall of the third gear 27 at the position of the rotating ring 29. A plurality of springs 31 are arranged in an annular array on the overload cylinder 28, one end of the spring 31 is fixedly connected to the overload cylinder 28, and the other end of the spring 31 is fixedly connected to a snap-fit ​​ball head 32, the snap-fit ​​ball head 32 is slidably connected in the rotating ring 29, the snap-fit ​​ball head 32 is correspondingly engaged with the snap-fit ​​groove 30, the rotating seat 25 and the gear ring 26 are both rotatably connected in the rotating groove 24, and a slot hole is opened on the overload cylinder 28 for slidingly sleeved with the prismatic transmission shaft 21.

[0043] In this embodiment, a slot is provided on the overload cylinder 28, which is slidably sleeved corresponding to the prismatic transmission shaft 21. Therefore, when the prismatic transmission shaft 21 rotates, the overload cylinder 28 can be driven to rotate. Because the overload cylinder 28 is sleeved on the prismatic transmission shaft 21, when the moving seat 16 is adjusted horizontally, the overload cylinder 28 can move synchronously with the moving seat 16 without hindering the rotation drive demand of the prismatic transmission shaft 21 for the overload cylinder 28. The overload cylinder 28 rotates on the inner wall of the third gear 27, and the engaging ball head 32 provided on the overload cylinder 28 is embedded in the engaging groove 30. When the overload cylinder 28 rotates, it can drive the third gear 27 to rotate synchronously, and the third gear 27 is meshed with the gear ring 26, so that the rotating seat 25 fixed on the inner wall of the gear ring 26 rotates on the moving seat 16. The engaging ball head 32 will be disengaged from the engaging groove 30, and the engaging ball head 32 will slide in the rotating ring 29 when overloaded, and the engaging ball head 32 will abut against the engaging groove 30 when overloaded, thereby forcing the engaging ball head 32 to abut against the spring 31 so that the spring 31 is squeezed and contracted in the slot hole on the outer wall of the overload cylinder 28 and maintains the rebound force. At this time, the engaging ball head 32 will be disengaged from the engaging groove 30, and the engaging ball head 32 will slide in the rotating ring 29, and the prismatic transmission shaft 21 will drive the overload cylinder 28 to rotate on the inner wall of the third gear 27, and the third gear 27 will not rotate with the overload cylinder 28, thereby realizing 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 so that the engaging ball head 32 is engaged in the engaging groove 30, so that when the overload cylinder 28 rotates, the third gear 27 can be driven to rotate again.

[0044] As a further solution of the present invention, the clamping mechanism includes a fixing ring 33 fixedly connected to the moving seat 16, a plurality of clamping plates 34 in an annular array and arranged in contact with one side of the fixing ring 33, and a positioning ring 35 arranged in contact with one side of the plurality of clamping plates 34; A sliding groove 36 is provided on one side of the fixing ring 33 close to the clamping plate 34, a sliding block 37 is fixedly provided on the corner of one side of the clamping plate 34, a connecting column 38 is fixedly provided at the center of the edge of the other side of the clamping plate 34, and a plurality of adjusting grooves 39 are provided in an annular array on the positioning ring 35; 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 .

[0045] 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.

[0046] 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.
