[0002] Sheep quarantine is an important measure to ensure the health of sheep and prevent and control the spread of diseases. The sheep quarantine process usually includes declaration, acceptance, pre-slaughter inspection, and simultaneous quarantine. During the quarantine process, quarantine personnel will conduct detailed observation and inspection of the sheep's health status, mental state, respiratory state, movement state, and excrement characteristics. At the same time, sheep meat products must also meet relevant standards and requirements, such as no off-odor, no spoilage, no fishy smell, and a white appearance.
[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, most traditional sampling devices use syringes to sample sheep blood. However, after sampling, the plunger inside the syringe is exposed to the outside. When subjected to external force, the plunger may move, causing the sampled blood to be ejected from the needle, resulting in waste of the sampled blood. Therefore, those skilled in the art have provided a sampling device to solve the problems mentioned in the background art. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sampling device. After a threaded cap is threaded onto the lower outer surface of the sampling tube, a silicone gasket can be used to seal the sampling tube. At the same time, the threaded block and needle are installed by threaded connection, which allows for convenient replacement of the needle. The movable rod with the mounting block can be disassembled after sampling, thus better protecting the sample in the sampling tube.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A sampling device includes a sampling cylinder, a threaded cap threadedly fitted on the lower end face of the sampling cylinder, a piston disposed on the inner surface of the sampling cylinder, an mounting block disposed on the upper end face of the piston, a movable rod fixedly disposed at the midpoint of the upper end face of the mounting block, an embedded block movably disposed on both sides of the mounting block, a bidirectional screw rotatably embedded at the lower end midpoint of the mounting block, and a threaded block embedded in the lower end face of the threaded cap.
[0006] Furthermore, an embedding groove is provided at the midpoint of the upper end face of the piston, and the mounting block is movably disposed in the embedding groove.
[0007] Furthermore, the two embedded blocks are threaded onto the outer surface of the bidirectional screw at the midpoint of their upper ends, and the two embedded blocks are respectively fitted and connected to the inner walls on both sides of the embedded groove.
[0008] Furthermore, a silicone plug is fixedly provided on the lower end face of the piston, and the outer surface of the silicone plug is in contact with the outer surface of the sampling tube.
[0009] Furthermore, the threaded cap is threaded onto the lower outer surface of the sampling cylinder, and a silicone pad is embedded at the midpoint of the lower end face of the threaded cap.
[0010] Furthermore, a needle is fixedly installed at the midpoint of the lower end face of the threaded block, and the upper end of the needle penetrates the silicone pad. The threaded block is threadedly embedded at the midpoint of the lower end face of the threaded cap.
[0011] Furthermore, a pull ring is fixedly provided on the upper end face of the movable rod, and handles are fixedly provided on both sides of the upper outer surface of the sampling tube, and a scale plate is embedded in the outer surface of the sampling tube near the front end.
[0012] This utility model has the following beneficial effects: 1. The sampling device proposed in this utility model, after a threaded cap is threaded onto the lower outer surface of the sampling tube, can be used with a silicone plug and silicone pad to form a sealed space inside the sampling tube. At the same time, after the threaded block is threaded into the lower end face of the threaded cap, a needle fixed at the midpoint of the lower end face of the threaded block can pass through the silicone pad. After sampling is completed, the threaded block can be rotated to remove the needle from the silicone pad for recycling and cleaning. The silicone pad and silicone plug also provide better sealing for the sampling tube.
[0013] 2. The sampling device proposed in this utility model has a piston that is movable inside the sampling tube. A silicone plug can be embedded in the lower end face of the piston. The silicone plug can increase the sealing of the inner wall of the sampling tube after it fits against the inner wall. At the same time, after an embedding groove is opened on the upper end face of the piston, a movable rod with a fixed mounting block can be fixedly installed on the upper end face of the piston. After pulling the pull ring on the upper end face of the movable rod, the movable rod can drive the piston and silicone plug to move in the sampling tube. This can be used with the threaded block and needle to sample sheep. After sampling, the movable rod can be disassembled by rotating the bidirectional screw, so as to better store the sampling tube.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Reference Figures 1 to 7 A sampling device includes a sampling cylinder 1, a threaded cap 3 threadedly fitted on the lower end face of the sampling cylinder 1, a piston 8 disposed on the inner surface of the sampling cylinder 1, an mounting block 9 disposed on the upper end face of the piston 8, a movable rod 5 fixedly disposed at the midpoint of the upper end face of the mounting block 9, an embedded block 11 movably disposed on both sides of the mounting block 9, a bidirectional screw 12 rotatably embedded at the lower end midpoint of the mounting block 9, and a threaded block 6 embedded in the lower end face of the threaded cap 3.
[0018] Specifically, after a threaded cap 3 is installed on the lower end face of the sampling cylinder 1, the sampling cylinder 1 can be sealed with the silicone plug 10 and silicone pad 14, thereby sealing and storing the sampled sample. At the same time, the piston 8 can move the silicone plug 10 in the sampling cylinder 1 under the pull of the movable rod 5. After the movable rod 5 and the mounting block 9 are fixedly connected, the mounting block 9 and the piston 8 can be fitted together. After rotating the bidirectional screw 12 in the mounting block 9, the inner walls on both sides of the embedding block 11 and the embedding groove 13 can be fitted together, thereby fixing the movable rod 5 to the upper end of the piston 8, so that the movable rod 5 can drive the piston 8 to move in the sampling cylinder 1.
[0019] Reference Figure 5 and Figure 6 An embedding groove 13 is provided at the midpoint of the upper end face of the piston 8, and the mounting block 9 is movably disposed in the embedding groove 13.
[0020] Specifically, after the upper end face of the piston 8 is opened with the embedding groove 13, the mounting block 9 with the movable rod 5 fixed thereon can be embedded into the embedding groove 13. The mounting block 9 can be installed or removed from the movable rod 5 as needed.
[0021] Reference Figure 6 Two embedded blocks 11 are threaded onto the outer surface of the bidirectional screw 12 at the midpoint of their upper ends, and the two embedded blocks 11 are respectively fitted and connected to the inner walls on both sides of the embedded groove 13.
[0022] Specifically, after the bidirectional screw 12 is rotatably embedded inside the mounting block 9, the upper end of the insert block 11 can be threaded onto both sides of the outer surface of the bidirectional screw 12. When the bidirectional screw 12 rotates, it can drive the insert block 11 and the two sides of the insert groove 13 to engage, thereby fixing the mounting block 9 to the upper end of the piston 8.
[0023] Reference Figure 6 A silicone plug 10 is fixedly installed on the lower end face of the piston 8, and the outer surface of the silicone plug 10 is in contact with the outer surface of the sampling tube 1.
[0024] Specifically, after fixing the silicone plug 10 to the lower end face of the piston 8, the outer surface of the silicone plug 10 can be made to fit with the sampling tube 1, thereby enabling the silicone plug 10 to provide better sealing to the sampling tube 1.
[0025] Reference Figure 7 The threaded cap 3 is threaded onto the lower outer surface of the sampling tube 1, and a silicone pad 14 is embedded at the midpoint of the lower end face of the threaded cap 3.
[0026] Specifically, after the threaded cap 3 is threaded onto the lower outer surface of the sampling cylinder 1, it can be used with the silicone plug 10 and piston 8 to store the collected sample. At the same time, after the silicone pad 14 is embedded in the lower end face of the threaded cap 3, it can provide the sealing of the sampling cylinder 1. The silicone pad 14 is made of self-healing material and can be used for multiple punctures.
[0027] Reference Figure 2 and Figure 7 A needle 15 is fixedly installed at the midpoint of the lower end face of the threaded block 6, and the upper end of the needle 15 penetrates the silicone pad 14. The threaded block 6 is threadedly embedded at the midpoint of the lower end face of the threaded cap 3.
[0028] Specifically, by inserting and fixing the needle 15 through the threaded block 6 at the midpoint of the lower end face, the sampling tube 1 can better sample the sheep through the needle 15. At the same time, by fixing the threaded block 6 to the lower end face of the threaded rod using a threaded connection, the needle 15 and the threaded block 6 can be easily disassembled and installed, which allows for better replacement and cleaning of the needle 15.
[0029] Reference Figure 1 and Figure 2 A pull ring 4 is fixedly installed on the upper end of the movable rod 5. Handles 7 are fixedly installed on both sides of the upper outer surface of the sampling tube 1. A scale plate 2 is embedded in the front end of the outer surface of the sampling tube 1.
[0030] Specifically, after setting a pull ring 4 on the upper end of the movable rod 5, it can be used in conjunction with the handle 7 fixed on the outer surface of the sampling tube 1 to better use the sampling device. At the same time, the working method of the sampling device is similar to that of a traditional rotating drum. After embedding a scale plate 2 on the outer surface of the sampling tube 1, the staff can observe the amount of sample in the sampling tube 1.
[0031] Working principle: In use, the operator can thread the threaded block 6 of the fixed needle 15 into the lower end face of the threaded cover 3. At the same time, the threaded cover 3 is threaded onto the lower end of the outer surface of the sampling tube 1. The sampling device can then be used. Before use, the operator needs to press the movable rod 5 with the pull ring 4 to move the piston 8 and the silicone plug 10 to the position of the threaded cover 3 on the sampling tube 1. During the movement of the piston 8, the gas inside the sampling tube 1 can be discharged. After the gas is discharged, the end of the sampling device containing the needle 15 can be inserted into the vein of the sheep. After pulling the pull ring 4 with the handle 7, the sample can be taken. After the sample is taken, the threaded block 6 can be rotated to remove the needle 15 for recycling and cleaning. At the same time, the bidirectional screw 12 in the mounting block 9 can be rotated to remove the movable rod 5. The sampling tube 1 and the threaded cover 3 can then be used to store the sample.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
