Description

Technical Field

[0001] The utility model relates to the field of test tube cleaning, in particular to a multifunctional test tube cleaning rack. Background Art

[0002] Test tubes are one of the commonly used instruments in chemical laboratories, usually made of glass or plastic. After use, the used test tubes are inserted into a cleaning rack and then cleaned uniformly. In the laboratories of scientific research institutions, a large number of test tubes need to be cleaned every day. The cleaning rack can make the whole cleaning process more standardized and efficient. However, the existing cleaning racks only play the role of placing test tubes and cannot automatically brush the inner walls of test tubes with a brush, resulting in low cleaning efficiency of test tubes.

[0003] After retrieval, Chinese Patent Publication No.: CN218692368U discloses a test tube cleaning rack, which includes a mesh basket rack. A plurality of horizontal tubes are fixed on the inner bottom wall of the mesh basket rack. A plurality of water spray nozzles are connected to the upper surfaces of the plurality of horizontal tubes. Brush structures are provided at the tops of the plurality of water spray nozzles. The brush structures include vertical rods, and bristles are provided on the side walls of the vertical rods. In this utility model, a mesh basket rack is provided. A plurality of horizontal tubes are arranged inside the mesh basket rack. A plurality of water spray nozzles are connected to the upper surfaces of the plurality of horizontal tubes. A brush structure is provided above each water spray nozzle. A rotary drive structure for driving the brush structure to rotate is provided inside the water spray nozzle. A test tube support plate is provided above the plurality of horizontal tubes. The test tube is sleeved on the surface of the brush structure, and the test tube is fixedly supported by the test tube support plate. When water is pumped into the horizontal tubes by a cleaning machine, the water sprays out from the water spray nozzles and enters the inside of the test tube, and the water flow drives the fan blades to rotate, and the fan blades drive the brush to rotate to clean the test tube, thereby realizing full-automatic cleaning and improving the cleaning efficiency.

[0004] In the above technology, through its designed structure, although the brush can clean the inner wall of the test tube, its water outlet end is below the brush, and at the same time, the brush only rotates circumferentially inside the test tube simply.

[0036] Refer toFigure 1 - Figure 2 、 Figure 4 、 Figure 7 The fixing component includes a clamping plate 42. The part of the clamping plate 42 in contact with the test tube is made of rubber material to ensure the stability of clamping and avoid damage to the test tube. The clamping plate 42 is slidably connected to the inner wall of the cross plate 2. The rear end of the left surface of the clamping plate 42 is fixedly connected to a round rod 47. A first through groove 45 is formed in the inner wall of the cross plate 2, and the round rod 47 is slidably connected to the inner wall of the first through groove 45.

[0037] Refer to Figure 4 、 Figure 6 The disassembly component includes a bolt 51. The bolt 51 is a prior art, which is a rod-shaped structure with external threads on its outer wall and is adapted to the threaded hole 53 to ensure the stability of connection. The bolt 51 is threadedly connected through the front surface of the top end of the telescopic tube 38. A threaded hole 53 is formed in the front surface of the bottom end of the brush 32. The outer wall of the rear end of the bolt 51 is threadedly connected to the inner wall of the threaded hole 53. The disassembly component further includes a sealing ring 52. The sealing ring 52 is fixedly connected to the lower surface of the brush 32 and is adapted to the sealing groove 54 to ensure the sealing between the telescopic tube 38 and the brush 32.

[0038] Refer to Figure 2 - Figure 4 The cleaning component further includes a motor 34. The motor 34 is a prior art and can be implemented by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The motor 34 is fixedly connected through the bottom end of the rear surface of the base 1. A round plate 33 is fixedly connected to the rear surface of the motor 34. A sliding rod 36 is rotatably connected to the rear surface of the round plate 33. A sliding groove 37 is formed in the rear surface of the rectangular sliding plate 35. The outer wall of the rear end of the sliding rod 36 is slidably connected to the inner wall of the sliding groove 37. The sliding rod 36 is specifically rotatably connected to the eccentric position of the rear surface of the round plate 33. When the round plate 33 rotates, since the sliding rod 36 is arranged at the eccentric position of the round plate 33, the front end of the sliding rod 36 will reciprocally slide on the inner wall of the sliding groove 37, thus driving the rectangular sliding plate 35 to reciprocally slide up and down.

[0039] Refer to Figure 4 、 Figure 7The fixed component also includes a guide plate 41, which is slidably connected to the upper surface of the cross plate 2. A through groove 46 is provided on the right surface of the guide plate 41.

One end of the spring 44 is fixedly connected to the rear surface of the pull rod 43, and the other end of the spring 44 is fixedly connected to the front surface of the cross plate 2.

[0040] Working principle: During use, when the test tube needs to be cleaned, the test tube can be turned upside down and passed through the horizontal plate 2. Before passing through the horizontal plate 2, the guide plate 41 needs to be pushed to separate the multiple groups of splints 42. Only the pull rod 43 needs to be pulled, and the pull rod 43 will stretch the spring 44 and detach from the inner wall of the groove. At this time, the guide plate 41 will fall under gravity, so that the round rod 47 will move along the slope of the through groove 46, and the round rod 47 will drive the splint 42 to move, so that the test tube can smoothly pass through the horizontal plate 2 and be sleeved on the outer wall of the brush 32, and then the guide plate 41 can be pushed in the reverse direction, so that the multiple groups of splints 42 will fix the test tube, and then the pull rod 43 is loosened, and the spring 44 will pull the pull rod 43 in the reverse direction through its own elasticity to insert into the inner wall of the groove, thereby limiting the guide plate 41.

[0041] When cleaning, the external pipes can be connected to the water inlet pipe 31, and then flushing can be carried out. Water enters the inner wall of the brush 32 through the inner wall of the telescopic tube 38, and then the test tube is flushed through the multiple water outlet holes 39. In the flushing process, the motor 34 can be started, the motor 34 will drive the circular plate 33 to rotate, and the circular plate 33 will drive the slide bar 36 to rotate around its center of the circle. At the same time, the front end of the slide bar 36 will slide on the inner wall of the slide groove 37, so that the rectangular slide plate 35 will reciprocate up and down, and at the same time, the rectangular slide plate 35 will drive the telescopic tube 38 to telescope and reciprocate up and down, and the brush 32 will also reciprocate up and down to clean the inner wall of the test tube.

[0042] When the brush 32 needs to be replaced, the bolt 51 can be rotated with a tool until the bolt 51 is disengaged from the inner wall of the threaded hole 53, and the brush 32 can be removed. When installing, the brush 32 is inserted into the inner wall of the top end of the telescopic tube 38, and the threaded hole 53 is aligned with the bolt 51, and then the bolt 51 is rotated in the opposite direction.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
