Description

Technical Field

[0001] This utility model relates to the technical field of laboratory glassware washing tools, and in particular to a multifunctional adjustable brush head test tube brush. Background Technology

[0002] In laboratory research and analysis testing in fields such as chemistry, biology, and medicine, glassware such as test tubes are the basic tools for carrying reactions and holding samples. After use, the inner walls of these glasswares often have residues attached to them. Cleaning the glasswares is a key prerequisite for ensuring the accuracy and precision of experimental results. Residues on the inner walls of the glasswares may lead to cross-contamination, reaction interference, large detection deviations, or even safety accidents.

[0003] Currently, cleaning such glassware mainly relies on the traditional tool of test tube brush. Test tube brush is a cleaning tool specially designed for laboratory glassware such as test tubes. It consists of a wire brush handle and nylon or pig bristle bristles. Its core function is to efficiently remove residues from the inner wall of the glassware, ensuring the cleanliness of the glassware and guaranteeing the accuracy of the experiment.

[0004] Existing test tube brushes have fixed brush head dimensions, which cannot be adapted to test tubes of different diameters. Multiple brushes are required, which is costly and space-consuming. Furthermore, the length of the brush handle is not adjustable, making it unsuitable for cleaning test tubes of different depths. Therefore, a multifunctional adjustable brush head test tube brush is proposed to solve the above problems. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 and Figure 2An embodiment of this utility model is provided: a multifunctional adjustable brush head test tube brush, including a shell 4, an inner shell 5 slidably connected inside the shell 4, an inner rod 7 rotatably connected inside the inner shell 5, a connecting component installed on the right side of the inner rod 7, a brush head 8 installed on the right side of the connecting component, and a bristle bundle 9 fixedly connected to the right side of the brush head 8. The brush head 8 can be quickly connected and disassembled through the connecting component to facilitate the replacement of the bristle bundle 9.

[0037] The connecting assembly includes a first sleeve 13, which is fixedly connected to the right side of the inner rod 7. A second threaded sleeve 14 is slidably connected to the outer side of the inner rod 7. A second sleeve 15 is threadedly connected to the inner side of the second threaded sleeve 14. The second sleeve 15 is fixedly connected to the left side of the brush head 8. After the first sleeve 13 and the second sleeve 15 are engaged, the second threaded sleeve 14 is tightened to the outer side of the second sleeve 15 by threads, thereby fixing the brush head 8 on the inner rod 7.

[0038] Reference Figure 1 , Figure 5 and Figure 6 An outer rod 6 is installed inside the outer shell 4. The inner shell 5 is slidably connected to the outside of the outer rod 6. The inner rod 7 is slidably connected to the inside of the outer rod 6. A retaining ring 17 is fixedly connected to the outside of the inner rod 7. The retaining ring 17 is rotatably connected to the inside of the inner shell 5. A locking assembly is installed on the right side of the outer shell 4. The inner shell 5 drives the inner rod 7 to move through the retaining ring 17, so that the inner rod 7 slides inside the outer rod 6 to achieve length extension and retraction adjustment. The length is then fixed by locking the assembly.

[0039] Reference Figure 1 and Figures 3-7 The locking assembly includes a threaded tube 10, with multiple clamping blocks 11 fixedly connected to the right side of the threaded tube 10. A threaded sleeve 12 is threadedly connected to the outer side of the threaded tube 10, and the threaded sleeve 12 is slidably connected to the outer side of the inner shell 5. After adjusting the length, the threaded sleeve 12 is tightened onto the outer side of the threaded tube 10, thereby clamping the clamping blocks 11 to lock the inner shell 5. A handle 1 is fixedly connected to the left side of the outer shell 4, and a motor 3 is installed inside the handle 1. The left side of the outer rod 6 is fixedly connected to the output end of the motor 3. Multiple locking strips 16 are fixedly connected to the outer side of the inner rod 7, and a sliding groove 18 is opened inside the outer rod 6. The rod 7 and the retaining strip 16 are slidably connected inside the slide groove 18. The motor 3 provides power to drive the outer rod 6 to rotate. The outer rod 6 drives the inner rod 7 to rotate through the retaining strip 16, thereby driving the brush head 8 and the bristle bundle 9 to rotate, so as to clean the inner wall of the test tube. The handle 1 has a battery 2 installed inside to power the motor 3. The handle 1 has a power button 19 installed on the outside. The power button 19, the battery 2 and the motor 3 are electrically connected. The power button 19 controls the rotation of the brush head 8 and the bristle bundle 9. The power button 19 is embedded in the handle 1 to prevent the power button 19 from being pressed by foreign objects when not in use, which would cause it to work ineffectively.

[0040] Working principle: The motor 3 drives the outer rod 6, inner rod 7 and brush head 8 to rotate in sequence, thereby rotating the bristle bundle 9 to brush and clean the inner wall of the test tube. After the first clamp 13 and the second clamp 15 are engaged, the second threaded sleeve 14 is tightened on the outside of the second clamp 15 by threads, thereby fixing the brush head 8 on the inner rod 7, realizing quick replacement and installation of the bristle bundle 9.

[0041] When the inner shell 5 slides inside the outer shell 4, the inner shell 5 will drive the inner rod 7 to move through the retaining ring 17, so that the inner rod 7 slides inside the outer rod 6 for length adjustment. The threaded sleeve 12 is tightened on the outside of the threaded tube 10 through the thread, so that the clamping block 11 clamps the inner shell 5 for locking to fix the length.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
