Description

Technical Field

[0001] The utility model belongs to the technical field related to medical experiments, and particularly relates to a medical experiment sampler. Background Technique

[0002] Medical inspection is a discipline that uses modern physical and chemical methods and means for medical diagnosis. It mainly studies how to provide a basis for clinical diagnosis and treatment through laboratory techniques and medical instrument equipment. Sampling is very crucial among them, which is related to the accuracy of the test results. In the process of sampling in medical experiments, a balanced and stable environment and equipment are required. When it is unbalanced, it will have a great impact on the accuracy of sampling and even affect the sampling results.

[0003] Chinese patent with publication number CN211262839U discloses a sampler for medical experiments that can accurately measure, including a sampling cylinder, a base, an arc-shaped fixing groove, and a threaded rod. On both sides of the top of the base, the arc-shaped fixing grooves perpendicular to the vertical direction are welded and fixed. On the base, the sampling cylinder movably penetrates through the inner wall of the arc-shaped fixing groove. The outer wall of the sampling cylinder fits and moves with the inner wall of the arc-shaped fixing groove. A rubber piston is movably arranged in the sampling cylinder. The center of the top of the rubber piston is rotationally connected to the threaded rod. The top of the threaded rod is threadedly penetrated through the top of the sampling cylinder and welded with a rotary handle. Fixed rods are adhesively fixed at symmetrical positions on the side wall of the sampling cylinder. Activity grooves matching the fixed rods are respectively opened in the arc-shaped fixing grooves. Screw holes are respectively arranged at the bottom of the activity grooves on the arc-shaped fixing grooves.

[0004] In the sampler of the above traditional technology, the sampling cylinder is fixed on the base, and the stability of sampling can be ensured through the base during sampling. However, in the actual use and operation process, there are still some deficiencies. For example, during sampling, the base needs to be placed above the liquid container, and then the sampling cylinder is used for stable sampling. However, when the liquid containers are at different heights or the liquid level height in the container cannot reach the required sampling amount, it is often necessary to further adjust the position of the sampling cylinder. Moreover, the sampling cylinder is fixed by symmetrically arranging two bolts at the lower end of the arc-shaped fixing groove, which is very inconvenient to adjust. Content of the Utility Model

When the sampling cylinder 6 is fixed, when sampling utensils with different heights or different liquid levels, only need to use the rocking handle 301 to rotate the rotating rod 305 to rotate inside the installation groove 304, so that the first bevel gear 306 on the rotating rod 305 meshes and drives the second bevel gear 307, and the first screw rod 303 connected to the second bevel gear 307 can rotate on the installation frame 2. Due to the rotation of the first screw rod 303, the placement plate 302 threadedly connected to the outer side can slide vertically up and down. After the liquid utensil is placed on the placement plate 302, it is convenient to make appropriate adjustments according to the sampling volume and the liquid level height, and there is no need to operate the fixing structure of the sampling cylinder 6. Therefore, it greatly facilitates the use and operation of experimenters;

[0024] The fixing mechanism 4 includes a fixing block 401. The fixing block 401 is fixedly installed on the front of the mounting frame 2. A square hole 402 is formed inside the fixing block 401, and a mounting cavity 405 is formed inside the fixing block 401. A clamping block 404 is slidably connected inside the mounting cavity 405. A second screw rod 407 is rotatably connected to the inner side of the front of the fixing block 401. One end of the second screw rod 407 is fixedly installed with a knob 406. The end of the second screw rod 407 away from the knob 406 extends into the inside of the mounting cavity 405. One end of the second screw rod 407 is threadedly connected to the clamping block 404. The end of the clamping block 404 away from the second screw rod 407 slidably extends into the inside of the square hole 402.

The rotation of the second screw rod 407 makes the clamping block 404 threadedly connected to the outside slide out from the mounting cavity 405 into the square hole 402, and the clamping grooves 403 on the clamping block 404 and the square hole 402 are engaged, so as to stably clamp and fix the sampling cylinder 6; a rubber layer is further provided inside the clamping groove 403, and the rubber layer can increase the friction-increasing effect with the outer surface of the sampling cylinder 6, thereby further enhancing the stability of clamping the sampling cylinder 6.

[0025] Reference Figure 1 , sliding rods 5 are symmetrically and fixedly installed inside the mounting frame 2. The placing plate 302 is slidably connected to the outside of the sliding rods 5. A threaded hole 8 is formed inside the placing plate 302. The placing plate 302 is threadedly connected to the first screw rod 303 through the threaded hole 8. By using the threaded connection between the placing plate 302 with the threaded hole 8 and the first screw rod 303, the placing plate 302 can vertically slide up and down on the sliding rods 5 of the mounting frame 2.

[0026] Reference Figure 1 , a placing groove 7 is formed at the upper end of the placing plate 302. The shape of the placing groove 7 is circular. By using the placing groove 7 on the placing plate 302, it is convenient to place the liquid container more stably.

[0027] Reference Figure 1, a screw groove 10 is provided at one end of the clamping block 404 away from the clamping groove 403. The clamping block 404 is threadedly connected to one end of the second screw rod 407 away from the knob 406 through the screw groove 10. Slide grooves 12 are symmetrically provided on the inner side of the installation cavity 405. A limiting frame 11 is fixedly installed on the outer side of one end of the clamping block 404 away from the clamping groove 403. The clamping block 404 is slidably connected to the slide groove 12 through the limiting frame 11. By threading one end of the second screw rod 407 with the screw groove 10 of the clamping block 404, the clamping block 404 can slide into the square hole 402 at the installation cavity 405 of the fixed block 401 to clamp the sampling cylinder 6. The limiting frame 11 on the outer side of one end of the clamping block 404 slides at the slide groove 12 of the installation cavity 405, which can slide and limit one end of the clamping block 404 in the installation cavity 405 to prevent it from coming out.

[0028] Reference Figure 3 and Figure 4 , one end of the fixed block 401 is fixedly connected to a fixing plate 9. The fixing plate 9 is fixedly installed on the installation frame 2 through screws. By using the fixing plate 9 with a round hole on the fixed block 401, it is convenient to fix the fixing plate 9 on the installation frame 2 with screws for use.

[0029] Principle and advantages of use: During the use process, when fixing the sampling cylinder 6, only need to insert the sampling cylinder 6 into the square hole 402 of the fixed block 401, and then rotate the knob 406, so that the knob 406 drives the second screw rod 407 to rotate on the fixed block 401. The rotation of the second screw rod 407 makes the clamping block 404 threadedly connected to the outside slide out from the installation cavity 405 into the square hole 402. By engaging the clamping block 404 with the clamping groove 403 with a rubber layer on the square hole 402, the sampling cylinder 6 can be stably clamped and fixed;

[0030] After the sampling cylinder 6 is fixed, place the liquid vessel in the placement groove 7 of the placement plate 302. When sampling vessels with different heights or different liquid levels, only need to use the crank 301 to rotate the rotating rod 305 to rotate inside the installation groove 304, so that the first bevel gear 306 on the rotating rod 305 meshes and drives the second bevel gear 307. The first screw rod 303 connected to the second bevel gear 307 can rotate on the installation frame 2. Due to the rotation of the first screw rod 303, the placement plate 302 threadedly connected to the outside can slide vertically up and down. After the liquid vessel is placed on the placement plate 302, it is convenient to make appropriate adjustments according to the sampling volume and the height of the liquid level.
