Description

Technical Field

[0001] The utility model relates to a splash-proof structure, in particular to a sample splash-proof structure for a friability tester. Background Art

[0002] A friability tester is a key instrument for evaluating the brittleness of pharmaceutical tablets or pills under mechanical stress, which is particularly important in the field of traditional Chinese medicine. Due to their complex ingredients, traditional Chinese medicine tablets and pills are prone to breakage or pulverization during processing, transportation, and storage. Friability testing can simulate these conditions to ensure the quality and stability of drugs. The use of a sample splash-proof structure is to protect the integrity of the medicinal material components, prevent sample loss and cross-contamination caused by the scattering of debris, thereby improving the accuracy of test results. The splash-proof structure can also ensure the cleanliness of the test environment, meet the standards and regulations of the traditional Chinese medicine industry, and ultimately guarantee the quality and safety of drugs.

[0003] In most cases, the existing splash-proof structures place the drugs in a container inside the instrument for tumbling detection to determine the hardness of the tested drugs. However, after continuous use, the container for placing the drugs needs to be cleaned. But each time, professional tools are required to remove the container for cleaning, which is not only time-consuming and laborious but also reduces the practicality of the instrument. Therefore, a sample splash-proof structure for a friability tester is proposed to solve the above problems. Summary of the Invention

Detailed implementation mode

[0021] The following combines the accompanying drawings and embodiments to further elaborate on the present utility model in detail. However, the protection scope of the present utility model is not limited by the embodiments.

[0022] As Figure 1 、 Figure 2 and Figure 3 shown, the sample anti-splash structure of the friability tester of the present utility model includes a body 1. A control panel 2 is fixedly connected to one side of the body 1. Symmetrically arranged transmission shafts 3 are rotatably connected inside the body 1. A sleeve 4 is sleeved on the outer wall of the transmission shaft 3. A protective cover 5 is fixedly connected to the outer wall of the sleeve 4. A first spring 6 is fixedly connected inside the transmission shaft 3. One end of the first spring 6 is fixedly connected to a hinge block 7. Symmetrically arranged connecting rods 8 are rotatably connected to the inner wall of the hinge block 7. One side of the outer wall of the connecting rod 8 is rotatably connected to a hinge seat 9. One side of the outer wall of the hinge seat 9 is rotatably connected to a positioning block 10. The positioning block 10 penetrates the transmission shaft 3 and is slidably connected inside the sleeve 4. A protective cover 11 is slidably connected to the outer wall of the protective cover 5. An adjustment assembly 12 for quickly disassembling the protective cover 5 is installed inside the protective cover 11. An arc plate 17 is fixedly connected to the inner wall of the protective cover 5; the adjustment assembly 12 includes a bolt 1201. The bolt 1201 is rotatably connected inside the protective cover 11. The bolt 1201 is attached to one side of the hinge block 7. The bolt 1201 is threadedly connected inside the transmission shaft 3. A knob 1202 is fixedly connected to one side of the outer wall of the bolt 1201.

[0023] By placing the medicine above the arc-shaped plate 17, firmly sleeving the sleeve 4 on the transmission shaft 3, and then fixing it through the engagement of the positioning block 10, it is ensured that the medicine will not shift or loosen during the transmission process. Subsequently, by installing the protective cover 11, the entire structure is comprehensively protected, effectively preventing the possible splashing phenomenon of the medicine during the detection process, and ensuring the cleanliness and safety of the experimental environment. When the body 1 is started, the protective cover 5 immediately starts to operate, thereby achieving the precise detection of the medicine. When it is necessary to remove the protective cover 5, by rotating the knob 1202, the bolt 1201 slowly disengages from the inside of the transmission shaft 3. Since the bolt 1201 separates from one side of the hinge block 7, the pressure of the first spring 6 is released. At this time, the reaction force of the first spring 6 pushes the hinge block 7 to move outward, further driving the connecting rod 8 to start rotating. As the connecting rod 8 rotates, the hinge seat 9 also rotates accordingly, and finally drives the positioning block 10 to gradually disengage from the inside of the sleeve 4, thus successfully completing the removal operation of the protective structure. This process not only ensures the safety and effectiveness of the operation, but also greatly facilitates the subsequent maintenance and cleaning work.

[0024] As Figure 3 , Figure 4 and Figure 5 shown, on one side of the outer wall of the transmission shaft 3, a fixed block 13 is fixedly connected, and the fixed block 13 is fixedly connected with a telescopic rod 14; one end of the telescopic rod 14 is fixedly connected with a fixed ring 15, and a second spring 16 is sleeved on the outer wall of the telescopic rod 14; on one side of the outer wall of the protective cover 5, a hinge 18 is fixedly connected, and on one side of the hinge 18, a protective door 19 is fixedly connected; on one side of the outer wall of the protective door 19, a clamping block 20 is fixedly connected, and the clamping block 20 is arranged on the adjacent side of the arc-shaped plate 17; on the outer wall of the protective cover 5, a buckle 21 is fixedly connected, and the buckle 21 is snap-connected with the clamping block 20; the inner diameter of the protective cover 11 is larger than the outer diameter of the protective cover 5, and the protective cover 11 covers the outer wall of the protective cover 5.

[0025] By opening the buckle 21 to disengage it from the outer wall of the clamping block 20, the operation becomes more flexible; at this time, the protective door 19 can easily rotate to one side with the support of the hinge 18, so as to conveniently put the medicine into the protective cover 5, simplifying the operation steps; during the disassembly process, the reaction force of the second spring 16 starts to take effect, pushing the telescopic rod 14 to perform telescopic movement, driving the fixed ring 15 to slide along the outer wall of the transmission shaft 3; the smooth movement of the fixed ring 15 enables the protective cover 5 to smoothly disengage from the transmission shaft 3, thereby realizing the disassembly of the protective cover 5. This mechanism not only improves the convenience and efficiency of the operation, but also ensures the stability and safety of the device.

[0026] The working principle of the present utility model is as follows: When in use, the buckle 21 is opened to disengage it from the outer wall of the clamping block 20. At this time, the protective door 19 is pulled to rotate on one side of the hinge 18. Then, the medicine is placed above the arc-shaped plate 17. Next, the sleeve 4 is sleeved on the transmission shaft 3 and fixed by the positioning block 10, and then it is protected by the protective cover 11, thus achieving the effect of preventing the medicine from splashing. Furthermore, by starting the machine body 1, the protective cover 5 is operated to achieve the detection effect; When it is necessary to remove the protective cover 5, the knob 1202 is rotated to make the bolt 1201 disengage from the inside of the transmission shaft 3. Since the bolt 1201 disengages from one side of the hinge block 7, the first spring 6 will lose pressure. At this time, the reaction force of the first spring 6 is used to push the hinge block 7 to move. Then, through the movement of the hinge block 7, the effect of driving the connecting rod 8 to rotate is achieved. Next, the connecting rod 8 drives the hinge seat 9 to rotate, thus achieving the effect of driving the positioning block 10 to disengage from the inside of the sleeve 4. At this time, the reaction force of the second spring 16 drives the telescopic rod 14 to expand and contract, thus achieving the effect of driving the fixing ring 15 to slide on the outer wall of the transmission shaft 3. At this time, the movement of the fixing ring 15 can achieve the effect of pushing the protective cover 5 to disengage from the transmission shaft 3.
