Technical Field

[0001] This utility model relates to the field of test tube cleaning technology, and in particular to a test tube cleaning device for school laboratories. Background Technology

[0002] A test tube cleaning device is a laboratory instrument used to automatically or semi-automatically clean, disinfect, and dry test tubes, ensuring that there are no residues on the inner walls of the tubes to maintain the accuracy of experimental results and the safety of reusing the tubes.

[0003] With its efficient, consistent, and safe cleaning performance, the test tube cleaning device can quickly process large numbers of test tubes, ensuring cleaning effectiveness while saving manpower and resources, improving laboratory work efficiency and space utilization, and enhancing laboratory safety by reducing human error and direct contact with harmful substances.

[0004] However, the following problems were found in the implementation of the relevant technology: When using existing test tube cleaning devices, they can generally only clean test tubes of a fixed size. When encountering test tubes of different sizes, they may be difficult to install due to size issues, thus making it impossible to use the test tube cleaning device to clean the test tubes. In view of this, a test tube cleaning device for school laboratories is provided to overcome the above defects. Utility Model Content

By setting the rotating motor, it is convenient to drive the fixed shell to rotate through the rotation of the rotating motor.

[0008] As a further description of the above technical solution: the two sides of the fixed shell are in contact with one side of the two clamping blocks, the knob is rotatably connected to the fixed shell, and the knob is rotatably connected to the clamping blocks. By setting the knob, it is convenient to drive the first drive gear to rotate by rotating the knob.

[0009] As a further description of the above technical solution: a threaded rod is fixedly connected to one side of the first driven gear, and there are two threaded rods. The threaded rods are helically connected to a moving block and a rubber block. By setting the threaded rods, it is convenient to drive the moving block to move by rotating the threaded rods.

[0010] As a further description of the above technical solution: the bottom end of the connecting shell is rotatably connected to a rotating sleeve, the inner side of the rotating sleeve is in contact with a water supply pipe, and the inner side of the connecting shell is provided with a water supply pipe. By providing a water supply pipe, it is convenient to rinse the test tube through the water supply pipe.

[0011] As a further description of the above technical solution: a micro motor is fixedly connected to the top of the inner side of the connecting shell, and a second drive gear is provided at the bottom of the inner side of the connecting shell. One end of the output shaft of the micro motor is fixedly connected to the top of the second drive gear.

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs a test tube cleaning device for school laboratories. Through a design and coordination, it combines components such as a fixed shell, a threaded rod, and a first driving gear. By rotating the knob, the first driving gear fixed to the knob is rotated. The rotation of the first driving gear then drives the first driven gear to rotate, which in turn drives the threaded rod to rotate. The rotation of the threaded rod causes the moving block to move towards the opposite direction, thereby causing the rubber block fixed to the moving block to come into contact with the test tube. Finally, the rubber block clamps and fixes test tubes of different sizes, preventing the test tubes from falling off during cleaning.

[0015] This utility model designs a test tube cleaning device for school laboratories. Through a design that combines components such as clamping blocks, a rotating motor, and an electric push rod, after the test tube is cleaned, the retraction of the electric push rod causes the clamping block fixed to the electric push rod to move downwards. Then, by activating the rotating motor, the fixed shell fixed to the output end of the rotating motor is rotated. By rotating the fixed shell, the test tube fixed to the fixed shell is rotated 180 degrees, so that the opening of the fixed shell faces the collection groove set at the top of the base plate, which facilitates the drainage of residual moisture inside the test tube after cleaning and accelerates the drying speed of the test tube.

By setting the second driven gear 19, it is convenient to drive the rotating sleeve 18 to rotate by rotating the second driven gear 19.

[0029] Working principle:

[0030] When using this invention, first insert the test tube to be cleaned into the round hole at the top of the fixed shell 9. Then, rotate the knob 8. The rotation of the knob 8 will cause the first driving gear 10 fixed at one end of the knob 8 to rotate. The first driving gear 10 is located inside the fixed shell 9 and meshes with the first driven gear 11. The rotation of the first driving gear 10 will cause the first driven gear 11 to rotate synchronously. The rotation of the first driven gear 11 will cause the threaded rod 12 fixed on the other side of the first driven gear 11 to rotate. The rotation of the two threaded rods 12 will cause the moving block 13, which is located inside the fixed shell 9 and slides against the fixed shell 9 and the round hole at the top of the fixed shell 9, to move towards each other. A rubber block 14 is fixed to one side of the movable block 13. Moving the movable block 13 causes the rubber block 14 to contact the side of the test tube inserted into the fixed shell 9, thus fixing the test tube in place and preventing it from easily shaking during cleaning. Several grooves are provided on one side of the rubber block 14, which increases the friction between the rubber block 14 and the test tube. After the test tube is fixed, the electric push rod 5 at the top of the base plate 1 is activated. The operation of the electric push rod 5 drives the clamping block 6 fixed to one end of the sliding rod of the electric push rod 5, the rotating motor 7 fixed to the clamping block 6, and the fixed shell 9 to move upwards synchronously. A connecting shell 2 is provided above the fixed shell 9, and the connecting shell 2 is fixedly connected to the base plate 1 via a support rod 4. A water supply pipe 15 is provided on the inner side of the connecting shell 2, and the water supply pipe 15 slides with the connecting shell 2. One end of the water supply pipe 15 extends to the outer side of the connecting shell 2 through a round hole opened at the bottom end of the connecting shell 2. A second driven gear 19 and a second driving gear 17 are provided on the inner side of the connecting shell 2. A rotating sleeve 18 is fixedly connected to the bottom end of the second driven gear 19. The rotating sleeve 18 covers the part of the water supply pipe 15 located on the outer side of the connecting shell 2. The top end of the second driving gear 17 is fixedly connected to one end of the output shaft of the micro motor 16. One end of the micro motor 16 is fixedly connected to the top end of the inner side of the connecting shell 2. When the top end of the fixed shell 9 contacts the bottom end of the connecting shell 2 under the drive of the electric push rod 5, the rotating sleeve 18 and part of the water supply pipe 15... The device will move accordingly to the inside of the test tube held by the fixed shell 9. Then, the micro motor 16 is activated, which drives the second drive gear 17 to rotate, thereby driving the second driven gear 19 to rotate synchronously. This, in turn, drives the rotating sleeve 18 to rotate, causing the wiping block fixed on the surface of the rotating sleeve 18 to contact the inner wall of the test tube. Combined with the rinsing of the water pipe 15, the inside of the test tube is effectively cleaned. After cleaning, the electric push rod 5 retracts, causing the fixed shell 9 to move downward. At this time, the rotating motor 7 located on one side of the clamping block 6 is activated. The rotation of the rotating motor 7 drives the fixed shell 9, which is fixed to the output shaft of the rotating motor 7, to rotate, thereby causing the test tube fixed by the fixed shell 9 to flip.By inverting the test tube, the moisture inside is poured into the collection groove 3 at the top of the base plate 1, thus accelerating the drying process.

[0031] In this utility model, the micro motor 16, the threaded rod 12, the rotary motor 7 and other components are all existing technologies, and their working principle is consistent with that of similar products on the market, so they will not be described in detail here.
