Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of laboratory test tube cleaning device, and more particularly to a laboratory test tube cleaning device. Background Technology
[0002] Pathology is a fundamental medical science that studies the causes, mechanisms, and development of human diseases, as well as the morphological, structural, functional, and metabolic changes in the body during disease progression and the outcome of the disease. Test tubes are frequently used in experiments, and cleaning them is a repetitive and physically demanding task, especially when cleaning a large number of test tubes.
[0003] Chinese patent publication number CN222710413U discloses a test tube cleaning device for biological experiments, including a main body of the device. The main body includes a base box with a drainage hole on one side. A bracket is fixedly connected to the top of the base box, and glass plates are fixedly connected to the sides of the bracket. A crossbar is fixedly connected to the top of the bracket. By setting a cover plate and a rubber pad, after the test tubes are placed, the cover plate is closed. The rubber pad prevents the test tubes from hitting the cover plate due to the upward impact of water pressure and breaking, effectively increasing the safety of the device. The glass plates facilitate observation of the real-time status of the test tube cleaning. By setting a hook, a fixing shaft, and a latch, the latch can be rotated upward to hook the hook when the cover plate is closed, which can fix the cover plate and prevent it from being pushed open during the cleaning of the test tubes, effectively enhancing the practicality of the device.

[0012] The beneficial effects of this utility model are:
[0013] When in use, this experimental test tube cleaning device has the following advantages:
[0014] 1. In this solution, a support plate, rotating shaft, connecting column, brushing assembly, support frame, support cylinder, fixed rod, slide groove, bidirectional screw, knob, connecting rod, through hole, stop rod, connecting pipe, diverter pipe, nozzle, fixed box, driven bevel gear, drive shaft, driving bevel gear, liquid storage tank, pump body, and infusion pipe are installed. Test tubes are inserted upside down into the support cylinder, with the connecting shaft and brush bristles inside the test tube and the nozzle facing inwards. Rotating the knob drives the bidirectional screw, which in turn moves the connecting rods on both sides of the support cylinder in opposite directions. The push rod passes through the corresponding through hole to clamp and fix the tail of the test tube.

The drive motor drives the transmission shaft and the active bevel gear to rotate, and the driven bevel gear meshing with it rotates accordingly. As a result, the rotating shaft, connecting column and brushing assembly rotate as a whole. With the water flow rinsing, the brush bristles brush the inner wall of the test tube to improve the cleaning effect. At the same time, multiple test tubes can be cleaned at the same time, which improves the cleaning efficiency and saves time and effort.

After cleaning, the cleaning component can be disassembled. Unscrew the fixing bolts on both sides, remove the connecting bracket as a whole, clean the brush bristles, or replace it with a new cleaning component to avoid the brush bristles being severely damaged after long-term use, which would affect the subsequent test tube cleaning effect.
