[0002] Veterinary laboratories are specialized laboratory facilities used for the diagnosis, prevention, control, and research of animal diseases. These laboratories, typically equipped with advanced equipment and specialized technicians, aim to improve animal health, ensure food safety, and promote the development of the livestock industry. Veterinary laboratories use sampling and testing, typically using swabs to collect blood or feces.

[0003] Existing sampling and testing devices used in livestock and veterinary laboratories require the swab to be completely placed in a test tube after sampling. The tail of the swab may contaminate the sample during subsequent processing, so the staff will break the swab. However, during the manual breaking process, the end of the swab will vibrate and easily fall out of the test tube. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a sampling and detection device for animal husbandry and veterinary laboratories.

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 - Figure 6 The sampling and testing device shown in the figure for animal husbandry and veterinary laboratories includes a test tube 1, a square tube 2 is fixedly installed on the top of the test tube 1, an opening is opened at the top of the square tube 2, a sliding cover mechanism 3 is installed above the square tube 2, and lifting mechanisms 4 are installed on both sides of the square tube 2. Two squeezing plates 20 are symmetrically arranged at the front end of the square tube 2, and the squeezing plates 20 are connected to the lifting mechanism 4. Through the cooperation of the sliding cover mechanism 3, the lifting mechanism 4 and the squeezing plates 20, when the opening at the top of the square tube 2 is opened, the staff can put the end of the swab into the square tube 2, and then the sliding cover mechanism 3, the lifting mechanism 4 and the squeezing plates 20 are gradually reset. The squeezing plate 20 has a squeezing effect on the broken part of the swab surface, so that the swab can be broken, and the end of the swab falls into the test tube 1 under the action of gravity.

[0021] The sliding cover mechanism 3 includes a top cover 6, which is slidably installed above the opening. A vertical plate 5 is provided at the rear of the square tube 2. The top of the vertical plate 5 is fixedly connected to the top cover 6, and the vertical plate 5 and the top cover 6 are combined into an L shape. A tension spring 7 is connected between the vertical plate 5 and the square tube 2. Connecting rods 8 are fixedly installed at both ends of the bottom of the vertical plate 5. Push blocks 9 are installed at the other ends of the two connecting rods 8, and the push blocks 9 are movably arranged in front of the square tube 2. When the staff presses the push block 9, the push block 9 gradually moves toward the direction of the vertical plate 5. At the same time, under the action of the connecting rod 8, the vertical plate 5 will move synchronously with the push block 9. The vertical plate 5 then drives the top cover 6 to slide on the surface of the opening, and the opening is gradually revealed, which is convenient for the staff to put the swab into the test tube 1. The tension of the tension spring 7 can reset the sliding cover mechanism 3.

[0022] A slide bar is provided at the bottom of the top cover 6, and a slide groove is provided on the inner wall of the opening. The slide bar is slidably engaged in the slide groove, thereby improving the smoothness of the top cover 6 sliding in the opening and ensuring the practicality and stability of the sliding cover mechanism 3.

[0023] The four end corners of the top cover 6 are fixedly provided with a clamping strip 10, which is slidably installed on the side of the square tube 2. A boss 11 is installed on the surface of the clamping strip 10 near one end of the pushing block 9. When the sliding cover mechanism 3 moves toward the rear of the square tube 2, the boss 11 will also move toward the rear of the square tube 2, and the horizontal height of the boss 11 does not change. The lifting mechanism 4 includes a connecting plate 16, and a path groove 12 is fixedly provided at the bottom of the connecting plate 16. The boss 11 is movably connected to the path groove 12. When the sliding cover mechanism 3 moves toward the rear of the square tube 2, the boss 11 will move in the path groove 12. A side panel 17 is provided, and a protruding plate 24 is fixedly provided at the bottom of the side panel 17. The protruding plate 24 is connected to the connecting plate 16 by bolts. A guide rod 18 is installed at the end of the surface of the side panel 17. A limit block 19 is fixed at the four end corners of the square tube 2. The surface of the guide rod 18 movably passes through the limit block 19. With the cooperation of the guide rod 18 and the limit block 19, the horizontal height of the lifting mechanism 4 can be changed. In the process of the sliding cover mechanism 3 moving toward the rear of the square tube 2, the boss 11 slides inside the path groove 12. When the boss 11 moves to different positions inside the path groove 12, the height of the lifting mechanism 4 will change.

[0024] Three paths are set inside the path groove 12, and the three paths are a first flat groove path 13, a second oblique groove path 14 and a third flat groove path 15. The first flat groove path 13 is close to the vertical plate 5, the third flat groove path 15 is close to the pushing block 9, and the second oblique groove path 14 is set between the first flat groove path 13 and the third flat groove path 15. When the boss 11 moves inside the first flat groove path 13, the horizontal height of the side plate 17 is higher than the square tube 2. When the boss 11 moves inside the second oblique groove path 14, the horizontal height of the side plate 17 will change. When the boss 11 moves inside the third flat groove path 15, the horizontal height of the side plate 17 is lower than the square tube 2.

[0025] The two squeezing plates 20 are respectively connected to the two side plates 17 by bolts. The adjacent surfaces of the two squeezing plates 20 are provided with inclined blocks 21. A groove 22 is provided under the inclined block 21. A squeezing wheel 23 is rotatably installed in the groove 22. The surface of the squeezing wheel 23 is provided with convex strips. When the opening is opened, the staff can insert the end of the swab into the opening, and the broken part of the swab surface is directly above the inclined block 21. After the tension of the tension spring 7 resets the sliding cover mechanism 3, the two side plates 17 gradually rise, and the squeezing wheel 23 has a squeezing effect on the broken part of the swab surface, so that the swab can be broken. The end of the swab falls into the test tube 1 under the action of gravity.

[0026] The surface of the pushing block 9 is provided with a matching arc edge 25, which corresponds to the surface of the test tube 1. When the staff pushes the pushing block 9 toward the surface of the test tube 1, the matching arc edge 25 can be close to the surface of the test tube 1, preventing the plane of the surface of the pushing block 9 from scratching the surface of the test tube 1.

[0027] Working principle: First, when the staff presses the push block 9, the push block 9 gradually moves toward the direction of the vertical plate 5. At the same time, under the action of the connecting rod 8, the vertical plate 5 will move synchronously with the push block 9. The vertical plate 5 then drives the top cover 6 to slide on the surface of the opening, and the opening is gradually revealed. In the process of the sliding cover mechanism 3 moving toward the rear of the square tube 2, the boss 11 slides from the third flat groove path 15 to the second inclined groove path 14, and then slides from the second inclined groove path 14 to the first flat groove path 13. After the opening is opened (the boss 11 is located in the first flat groove path 13), the horizontal height of the side plate 17 is lower than the square tube 2. Tube 2, then the staff inserts the end of the swab into the opening, and the broken part on the surface of the swab is just above the inclined block 21, and then the tension of the tension spring 7 can gradually reset the sliding cover mechanism 3. At this time, the boss 11 slides from the first flat groove path 13 to the second inclined groove path 14, and then slides from the second inclined groove path 14 to the third flat groove path 15. At this time, the horizontal height of the side plate 17 is higher than the square tube 2, and the two side plates 17 also gradually rise. The squeezing wheel 23 has a squeezing effect on the broken part on the surface of the swab, so that the swab can be broken, and the end of the swab falls into the test tube 1 under the action of gravity.
