Description

Technical Field

[0001] This application relates to the field of laboratory equipment technology, and in particular to a test tube cleaning device for chemical laboratories. Background Technology

[0002] In the daily operation of a laboratory, the cleaning of various instruments is a crucial step in ensuring the smooth progress of experiments and the accuracy and reliability of results. Among these, test tubes, as one of the most basic and frequently used experimental instruments, directly impact the conduct of subsequent experiments through their cleaning effectiveness and efficiency. For a long time, the cleaning of test tubes has faced the challenge of inconvenient operation.

[0003] Currently, most laboratories use a traditional and simple method for cleaning test tubes, typically rinsing them in a regular water tank. While this method can remove some visible stains from the surface and interior of the test tubes, it has several significant drawbacks. Firstly, due to the lack of effective positioning devices, the test tubes are left to move freely in the tank, making them prone to shaking and tipping over. Secondly, the faucets in regular water tanks are usually in fixed positions. However, test tubes of different sizes have varying requirements for water flow. Fixed faucet positions cannot be flexibly adjusted to meet these needs, forcing cleaning personnel to constantly adjust the test tube positions, which undoubtedly reduces cleaning efficiency and increases the difficulty and labor intensity of the process.

[0021] This application provides a test tube cleaning device for a chemical laboratory, such as... Figures 1 to 4 As shown, the test tube cleaning device for a chemical laboratory includes: a base 1 with a water tank 7 on top; a support rod 2 vertically mounted on the top of the base 1; a lifting assembly 6 mounted on the side wall of the base 1; a support plate 3 fitted onto the outer wall of the support rod 2 and connected to the output end of the lifting assembly 6, the support plate 3 being able to move up and down axially along the support rod 2; a connecting block 4 located at the end of the support plate 3 away from the support rod 2, its bottom connected to a spray pipe 5, and its side wall connected to a water pipe from an external water source; two clamping assemblies 9 symmetrically distributed on both sides of the center line of the water tank 7, one end of each clamping assembly 9 fixed to the base 1; and two clamping blocks 8 respectively located at the free ends of the two clamping assemblies 9, forming an area between the two clamping blocks 8 for clamping the test tubes.

[0022] It should be noted that this application uses the lifting assembly 6 to drive the support plate 3 to rise and fall axially along the support rod 2, thereby adjusting the connecting block 4 and the spray pipe 5 to a suitable height. External water is supplied to the connecting block 4 through a water pipe and sprayed out from the spray pipe 5. Using the clamping assemblies 9 symmetrically distributed on both sides of the center line of the water tank 7, the clamping blocks 8 at their free ends are manipulated to clamp and fix the test tubes in a specific area, thereby achieving precise rinsing of the test tubes at different heights. Therefore, this device effectively solves the problems of inability to position the test tubes and difficulty in adjusting the fixed water outlet position in traditional test tube cleaning. It can flexibly adjust the height of the spray pipe 5 according to the test tube specifications and the degree of contamination, accurately position the test tubes for efficient cleaning, reduce cleaning difficulty and labor intensity, and improve cleaning efficiency and quality.

[0023] In this embodiment, the lifting assembly 6 includes a motor 601, a transmission rod 602, and a transmission cylinder 603. The motor 601 is fixedly connected to the side wall of the base 1. The output end of the motor 601 is coaxially connected to the transmission rod 602. The transmission cylinder 603 is sleeved on the outer wall of the transmission rod 602, and the side of the transmission cylinder 603 away from the motor 601 is connected to the support plate 3. The outer wall of the transmission rod 602 is provided with external threads, and the inner cavity of the transmission cylinder 603 is provided with internal threads that match the external threads.

[0024] It should be noted that when the height of the support plate 3 and the spray pipe 5 needs to be adjusted to accommodate the cleaning requirements of different test tubes, the motor 601, which is fixedly connected to the side wall of the base 1, is activated. The motor 601 operates, and its output end begins to rotate. Since the output end of the motor 601 is coaxially connected to the transmission rod 602, it drives the transmission rod 602 to rotate synchronously. The outer wall of the transmission rod 602 is provided with external threads, while the inner cavity of the transmission cylinder 603 is provided with matching internal threads. During the rotation of the transmission rod 602, according to the principle of threaded transmission, the transmission cylinder 603 will move along the axial direction of the transmission rod 602 under the interaction of the threads. Furthermore, because the side of the transmission cylinder 603 away from the motor 601 is connected to the support plate 3, the movement of the transmission cylinder 603 will drive the support plate 3 to move axially up and down along the support rod 2 vertically set at the top of the base 1, thereby achieving the adjustment of the height of the support plate 3 and the connecting block 4 and spray pipe 5 connected to it. Therefore, by using the motor 601 drive and threaded transmission, this application can precisely control the lifting height of the support plate 3 and the spray pipe 5, thereby accurately adjusting the spray pipe 5 to the most suitable rinsing position according to test tubes of different specifications and with different contamination conditions, ensuring comprehensive and effective cleaning of the inside of the test tubes, and improving the accuracy and targeting of the cleaning.

[0025] In this embodiment, the clamping assembly 9 includes a connecting plate 901, a positioning block 902, a spring 904, and two positioning rods 903. One end of the connecting plate 901 is fixedly connected to the clamping block 8, and the other end is fixed with two positioning rods 903 at intervals along its length. The positioning block 902 is fixed to the base 1, and the ends of the two positioning rods 903 away from the connecting plate 901 pass through the positioning block 902 and slide with it. The extension direction of the positioning rods 903 is parallel to the clamping movement direction of the clamping block 8. The two ends of the spring 904 are connected to the positioning block 902 and the connecting plate 901, and the elastic clamping force on the test tube is generated by the compression deformation of the spring 904.

[0026] It should be noted that when the test tube needs to be clamped, the operator overcomes the elastic force of the spring 904 and pulls the connecting plate 901 outward. The connecting plate 901 drives the two positioning rods 903, which are fixedly connected to it, to slide within the positioning block 902 along a direction parallel to the clamping movement of the clamping block 8. At this time, the spring 904 is compressed. After the test tube is placed between the two clamping blocks 8, the connecting plate 901 is released. Under the elastic force of the spring 904 restoring its deformation, the spring 904 pulls the connecting plate 901. The connecting plate 901 drives the positioning rods 903 to slide in the opposite direction within the positioning block 902, thereby causing the clamping block 8 to move towards the test tube, ultimately achieving elastic clamping of the test tube. Therefore, this application utilizes the elastic clamping force generated by the compression deformation of the spring 904 to clamp the test tube. This elastic clamping method can automatically adjust the clamping force according to the size and shape of the test tube, avoiding damage to the test tube due to excessive clamping force, while also ensuring the stability of the clamping and effectively protecting the safety of the test tube during the cleaning process.

[0027] Of course, this application is not limited to the above structure. The clamping assembly 9 in this embodiment includes a connecting plate 901, a spring 904, and two positioning rods 903. One end of the connecting plate 901 is fixedly connected to the clamping block 8, and the other end is slidably connected to the two positioning rods 903 at intervals along its length, so that the connecting plate 901 can move axially along the positioning rods 903. The ends of the two positioning rods 903 away from the connecting plate 901 are fixedly connected to the side wall of the water tank 7, providing stable support and guidance for the movement of the connecting plate 901, and the extension direction of the positioning rods 903 is parallel to the clamping movement direction of the clamping block 8. The two ends of the spring 904 are respectively connected to the side wall of the water tank 7 and the side of the connecting plate 901 away from the clamping block 8. When it is necessary to clamp the test tube, the operator overcomes the elastic force of the spring 904 and pushes the connecting plate 901 along the positioning rod 903 in a direction away from the side wall of the water tank 7. At this time, the spring 904 is compressed. After the test tube is placed between the two clamping blocks 8, the connecting plate 901 is released. Under the elastic force of the spring 904 restoring its deformation, the spring 904 pulls the connecting plate 901. The connecting plate 901 moves along the positioning rod 903 in a direction closer to the side wall of the water tank 7, thereby causing the clamping blocks 8 to move towards the test tube, and finally achieving elastic clamping of the test tube.

[0028] In this embodiment, the inner side of the clamping block 8 is provided with an anti-slip rubber layer. The clamping surface of the clamping block 8 is an arc-shaped structure adapted to the outer wall of the test tube.

[0029] It should be noted that the anti-slip rubber layer significantly increases the friction between the clamping block 8 and the outer wall of the test tube, effectively preventing the test tube from slipping or shifting due to water flow impact or operational vibration during the cleaning process, thus ensuring the stable operation of the cleaning work.

[0030] In this embodiment, a drain hole is provided at the bottom of the water tank 7, and the drain hole is connected to an external drainage pipe. The drain hole at the bottom of the water tank 7 is connected to the external drainage pipe, which can discharge the wastewater after cleaning the test tubes in a timely and smooth manner, avoiding the accumulation of wastewater in the water tank 7, and preventing wastewater backflow or bacterial growth that may affect subsequent cleaning and the laboratory environment.

[0031] In this embodiment, the spray pipe 5 has a multi-hole spray structure, and its axis is parallel to the axis of the clamping block 8 that holds the test tube. The multi-hole spray pipe 5 and the parallel axis of its axis with the test tube axis can make the water flow uniform and comprehensive on the inner wall of the test tube, achieving efficient and thorough rinsing without dead corners, significantly improving the cleaning effect and efficiency of the test tube, and ensuring the cleanliness quality of laboratory equipment.

[0032] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0033] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
