DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1: An enrichment chamber 8 is installed at the top of the base 1, a threaded rod 11 is movably installed inside the enrichment chamber 8, a rotating seat 16 is installed at the bottom end of the threaded rod 11, a sealing cover 17 is installed at the bottom end of the rotating seat 16, a handwheel 12 is installed at the top of the threaded rod 11, a ventilation pipe 15 is installed at the top of the sealing cover 17, a filter screen 14 is installed at the top of the ventilation pipe 15, an injection pipe 9 is installed at the top of the sealing cover 17, a threaded cover 10 is installed at the top of the injection pipe 9, a handle 13 is movably installed at the top of the enrichment chamber 8, a support pad 4 is installed at the bottom end of the base 1, and the threaded rod 11 is meshed with the inside of the enrichment chamber 8 through a threaded groove.

[0020] Specifically, Figure 1 and Figure 3 As shown, the threaded rod 11 can be driven to rotate by shaking the hand wheel 12. Since the threaded rod 11 is connected to the inside of the enrichment chamber 8 through threaded engagement, when the threaded rod 11 rotates, the bottom end of the threaded rod 11 will move up and down inside the enrichment chamber 8. Since the bottom end of the enrichment chamber 8 is installed with a sealing cover 17 through a rotating seat 16, when the bottom end of the threaded rod 11 moves up and down inside the enrichment chamber 8, the sealing cover 17 can be driven to move synchronously. Since a ventilation pipe 15 and an injection pipe 9 are respectively installed on both sides of the top of the sealing cover 17, and the outer sides of the ventilation pipe 15 and the injection pipe 9 are respectively slidably installed inside the enrichment chamber 8, the sealing cover 17 will not rotate inside the enrichment chamber 8, but will only move up and down. By controlling the sealing cover 17 Moving downward can seal the top of the culture dish placed in the enrichment chamber 8 to prevent the liquid in the culture dish from leaking during the movement of the device. The culture dish can be ventilated through the ventilation tube 15, and impurities in the air can be filtered through the filter 14. By opening the threaded cover 10 installed on the top of the injection tube 9, the culture solution can be injected into the culture dish placed under the sealing cover 17 through the injection tube 9, thereby avoiding the need to take the culture dish out of the enrichment chamber 8 and then add culture solution, and avoiding the liquid in the culture dish from leaking, thereby ensuring the accuracy of the biological enrichment results. Since a handle 13 is movably installed on the top of the enrichment chamber 8, the entire device can be conveniently carried by the handle 13.

[0021] Embodiment 2: A support slide bar 25 is installed inside the base 1, and a second slide bar 26 is provided on the outer sliding sleeve of the support slide bar 25. A pull-out plate 18 is installed on the top of the second slide bar 26. A double-threaded screw rod 3 is installed inside the pull-out plate 18, and a first slide bar 5 is respectively provided on the outer sides of both ends of the double-threaded screw rod 3. The two first slide bars 5 are respectively connected to the double-threaded screw rod 3 through threaded engagement. A clamping plate 2 is installed on the top of the first slide bar 5. A mounting groove 19 is provided on one side of the pull-out plate 18, and a knob 2 is installed inside the mounting groove 19. 0, slide plates 21 are respectively installed on both sides of the pull-out plate 18, a transparent door panel 23 is installed on one side of the pull-out plate 18, and a handle 22 is installed on one side of the transparent door panel 23, a rotation limit rod 7 is respectively installed on both sides of the enrichment chamber 8, and the rotation limit rod 7 is used in conjunction with the transparent door panel 23, a limit slide groove 24 is respectively opened on both sides of the inner wall of the enrichment chamber 8, and the limit slide groove 24 is used in conjunction with the slide plate 21, the output end of the knob 20 extends into the interior of the pull-out plate 18, and the output end of the knob 20 is connected to one end of the double-threaded rod 3.

[0022] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the culture dish is placed on the top of the pull-out plate 18, and then the double-threaded rod 3 is driven to rotate by rotating the knob 20. The rotation of the double-threaded rod 3 can drive the two clamping plates 2 to slide relative to each other at the top of the base 1, thereby clamping the two sides of the culture dish, thereby preventing the culture dish from shaking randomly above the pull-out plate 18. The situation inside the enrichment chamber 8 can be observed at all times through the transparent door panel 23, and the pull-out plate 18 can be pulled out of the enrichment chamber 8 through the handle 22. When pulling out, the second slider 26 will slide along the installation direction of the supporting slider 25. At the same time, the slides 21 installed on both sides of the pull-out plate 18 will slide in the limiting slide groove 24, thereby ensuring the stability of the pull-out plate 18 during the process of being pulled out. The rotating limiting rods 7 installed on both sides of the rotating enrichment chamber 8 can limit one side of the transparent door panel 23, thereby preventing the pull-out plate 18 from automatically sliding out of the enrichment chamber 8 during the movement of the device.

[0023] Working principle: When in use, the pull-out plate 18 is drawn out from the inside of the enrichment chamber 8, and then the biological enrichment culture dish is placed on the top of the pull-out plate 18, and then the double-threaded rod 3 is driven to rotate by rotating the knob 20. The rotation of the double-threaded rod 3 can drive the two clamping plates 2 to slide relative to each other on the top of the base 1, thereby clamping the two sides of the culture dish, thereby preventing the culture dish from shaking randomly above the pull-out plate 18. Then, the pull-out plate 18 is sent into the enrichment chamber 8 together with the culture dish, and the transparent door panel 23 is limited by rotating the rotation limit rod 7. The sealing cover 17 can be driven to move downward inside the enrichment chamber 8 by shaking the hand wheel 12. By controlling the downward movement of the sealing cover 17, the top of the culture dish placed inside the enrichment chamber 8 can be The culture dish is sealed to prevent the liquid inside the culture dish from leaking during the movement of the device. The culture dish can be ventilated through the ventilation tube 15. By opening the threaded cover 10 installed on the top of the injection tube 9, the culture solution can be injected into the culture dish placed under the sealing cover 17 through the injection tube 9, thereby avoiding the need to take the culture dish out of the enrichment chamber 8 and then add culture solution, avoiding the liquid inside the culture dish from leaking, and ensuring the accuracy of the biological enrichment result. Subsequently, the entire device can be carried by the handle 13 installed on the top of the enrichment chamber 8. Therefore, the biological sample can be quickly enriched through the high device, and liquid will not leak during the biological enrichment process, thereby improving the accuracy of the biological enrichment result.
