For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0019] See attached document Figure 1-5 A test tube cleaning device for a biomedical laboratory includes a water tank 1. A mounting column 5 is positioned at the top of the water tank 1. Guide grooves 6 are formed on both sides of the mounting column 5. A lifting ring 7 is slidably connected to the bottom of the inner wall of the mounting column 5. A return spring 12 is positioned between the lifting ring 7 and the mounting column 5. Rotating strips 8 are rotatably connected to both sides of the outer walls of the mounting column 5 and the lifting ring 7. A cleaning sponge 9 is positioned between the two rotating strips 8. A water groove 10 is formed on the outer wall of the cleaning sponge 9. A connecting hose 11 is positioned on one side of the cleaning sponge 9, and the connecting hose 11 passes through the lifting ring 7. A sealing cap 19 is provided on the outer wall of the water tank 1. When the lifting ring 7 moves downward along the mounting column 5, it compresses the return spring 12, causing the rotating strips 8 to change their angle, thus expanding the cleaning sponge 9 radially to fit against the inner wall of the test tube. The cleaning solution in the water tank 1 is pumped into the water groove 10 through the connecting hose 11. The moistened cleaning sponge 9 simultaneously performs physical friction and liquid rinsing during rotation. The elastic force of the return spring 12 ensures that the cleaning sponge 9 maintains moderate contact pressure with the inner wall of the test tube, avoiding scratches caused by rigid contact. After the sealing cap 19 is closed, it forms a closed cavity, preventing splashes of liquid containing biohazardous substances from spreading to the external environment. After cleaning is completed, the external force is removed, the return spring 12 pushes the lifting ring 7 to reset, and the rotating bar 8 retracts, causing the cleaning sponge 9 to detach from the test tube.

[0020] Furthermore, the water tank 1 is equipped with a partition 2 inside, a lifting device 3 inside, a drain outlet 4 at the top of the water tank 1, a motor inside the water tank 1, and the water tank 1 is divided into upper and lower layers by a partition. The upper layer of the water tank 1 is used to connect to the drain outlet 4, and the lower layer stores cleaning fluid, which is pumped into the water tank 10 through a water pump connected to a hose 11.

[0021] Furthermore, the outer wall of the mounting column 5 is provided with a meshing gear 13, the top of the water tank 1 is provided with a meshing toothed ring 18, the meshing toothed ring 18 is connected to the meshing gear 13, and the number of mounting columns 5 is set to multiple.

[0022] Furthermore, the top of the water tank 1 is provided with an installation pipe 14, and auxiliary grooves 15 are provided on both sides of the outer wall of the installation pipe 14. The output end of the motor is provided with a transmission screw 16, which is rotatably connected to the inner wall of the installation pipe 14. The outer wall of the transmission screw 16 is provided with a test tube clamping device 17. The meshing gear 13 refers to a gear structure fixed to the outer wall of the mounting column 5. It can be implemented using helical gears or spur gears, and its tooth profile matches that of the meshing gear ring 18 to transmit rotational power. This gear, through meshing with the gear ring, ensures the synchronous rotation of multiple mounting columns 5.

[0023] The meshing gear ring 18 refers to the ring gear component located on the top of the water tank 1. Specifically, it can be implemented using an internal gear ring structure with continuous teeth distributed on its inner circumference for simultaneous meshing with multiple meshing gears 13. This gear ring serves as a central transmission unit, driving all mounting columns 5 through a single power input.

[0024] The multiple mounting columns 5 refer to columnar support structures distributed circumferentially along the top of the water tank 1. They can be made of stainless steel or engineering plastics, and each mounting column 5 independently supports the cleaning sponge 9 and the lifting assembly. By increasing the number of mounting columns 5, parallel cleaning of multiple test tubes can be achieved.

[0025] The meshing relationship between the meshing gear 13 and the meshing toothed ring 18 ensures that all mounting posts 5 maintain the same angular velocity during rotation. When an external power drives the meshing toothed ring 18 to rotate, the teeth on the inner wall of the ring contact the meshing gear 13 of each mounting post 5, forcing the gears to rotate synchronously. The rotating gears then drive the mounting posts 5 to rotate at the top of the water tank 1, which in turn drives the cleaning sponge 9 to rotate, causing the inclined sponge to rotate inside the test tube. Multiple mounting posts 5 are evenly distributed along the top of the water tank 1, with each mounting post 5 corresponding to a test tube to be cleaned. Synchronous rotation ensures that the friction force on the inner wall of each test tube is uniform, preventing incomplete cleaning of some test tubes due to differences in rotation speed.

[0026] When the motor drives the lead screw 16 to rotate, the test tube clamping device 17 engages with the threaded connection of the lead screw 16 through the mating hole 1705, moving axially along the mounting tube 14. The sliding fit between the auxiliary groove 15 and the bracket 1704 forms a double-track guide, eliminating radial offset of the test tube clamping device 17 during lifting. The rotational connection design between the inner wall of the mounting tube 14 and the lead screw 16 disperses the transmission torque, preventing lead screw deformation due to uneven load. Driven by the lead screw 16, the test tube clamping device 17 achieves automated lifting, keeping the test tubes vertically positioned during cleaning, and replacing manual adjustment of the test tubes through mechanical linkage. Furthermore, the test tube clamping device 17 includes a placement ring 1701 with a placement groove 1702 inside. Rubber strips 1703 are provided on both sides of the inner wall of the placement groove 1702. A bracket 1704 is provided in the middle of the placement ring 1701, and the bracket 1704 is slidably connected to the auxiliary groove 15. A mating hole 1705 is provided in the middle of the bracket 1704, which engages with the transmission screw 16. When the test tube is vertically inserted into the placement groove 1702, its outer wall forms a three-point contact with the rubber strips 1703 on both sides. The radial pressure generated by elastic deformation keeps the test tube vertical. The bracket 1704, through the engagement of its sliding flange with the auxiliary groove 15, constrains the movement trajectory of the clamping device during lifting and lowering. When the transmission screw 16 rotates, the thread in the mating hole 1705 converts the rotational motion into linear displacement, driving the entire clamping device to move along the direction of the auxiliary groove 15. This structure allows the test tube to maintain a fixed posture during the cleaning process while also achieving precise lifting and lowering with the transmission system.

[0027] Furthermore, the lifting device 3 includes an auxiliary ring 301. An electric push rod is installed between the auxiliary ring 301 and the water tank 1. Four sliding holes 302 are provided inside the auxiliary ring 301. Pins 303 are installed on both sides of the top of each sliding hole 302, and these pins 303 are aligned with the lifting ring 7. The auxiliary ring 301 is driven by the electric push rod to move up and down, replacing the traditional manual adjustment method. The four sliding holes 302 are evenly distributed inside the auxiliary ring 301, forming symmetrically distributed guide channels, ensuring the lifting ring 7 maintains vertical stability during movement. When the electric push rod pushes the auxiliary ring 301 upward, the two pins 303 at the top of the sliding holes 302 contact the edge of the lifting ring 7, and the horizontal position of the lifting ring 7 is corrected in real time through mechanical limiting, ensuring that the cleaning sponge 9 maintains uniform contact with the outer wall of the test tube. This structure achieves precise control of the movement trajectory of the lifting ring 7 through the synergistic effect of electric drive and mechanical positioning. The test tube is placed inside the test tube clamping device 17 and fixed. Then the motor is started, and the motor drives the transmission screw 16 to rotate. The transmission screw 16 drives the test tube clamping device 17 and the test tube inside to move downward, so that the inner wall of the test tube contacts the cleaning sponge 9. Then the external drive rotating gear ring rotates, the rotating gear ring drives the rotating gear to rotate, the rotating gear drives the mounting column 5 to rotate, and the mounting column 5 drives the cleaning sponge 9 to clean the inside of the test tube. Then the water pump sends the cleaning liquid at the bottom of the water tank 1 into the water tank 10. The opening of the test tube is downward, and the liquid after tilting enters the top of the inner wall of the water tank 1 through the drain 4.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
