[0030] Example:
[0031] Please see Figures 1-4 An experimental apparatus for ultraviolet-induced fungal mutagenesis includes an experimental cabinet body 1, with a movable cabinet door 2 rotatably connected to the outer end of the experimental cabinet body 1. Four evenly distributed ultraviolet irradiation lamps 3 are installed at the top of the inner wall of the experimental cabinet body 1. Two lifting bars 4 are fixedly connected to the left and right inner walls of the experimental cabinet body 1. Lifting blocks 5 are slidably connected to the outer ends of the lifting bars 4. A partition 6 is installed inside the lifting blocks 5. In actual use, an appropriate number of lifting blocks 5 and partitions 6 can be set in the 1 according to the needs of the experiment. A through hole 7 is drilled at the outer end of the lifting block 5. A positioning block 8 is slidably connected to the through hole 7. A connecting plate 9 is fixedly connected inside the lifting block 5. The connecting plate 9 is located outside the positioning block 8. A screw 10 is threadedly connected to the connecting plate 9. The screw 10 is located at the outer end of the positioning block 8 and is rotatably connected to the positioning block 8. Multiple evenly distributed positioning grooves 11 that match the positioning blocks 8 are drilled at the outer ends of the lifting bars 4.
[0032] Please see Figures 3-4The outer end of the lifting bar 4 has two symmetrical grooves 401. The end of the lifting block 5 near the lifting bar 4 is fixedly connected to a slider 501. The slider 501 is located in the groove 401 and is slidably connected to the groove 401. By setting the groove 401 and the slider 501, the sliding between the lifting block 5 and the lifting bar 4 can be made more stable. At the same time, it can also make it difficult for the lifting block 5 and the lifting bar 4 to separate after the partition 6 is removed. The contact points between the lifting block 5 and the partition 6 are fixedly connected to buffer pads 502. The buffer pads 502 are made of rubber material. By setting the buffer pads 502, the possibility of damage to the partition 6 in the lifting block 5 can be reduced, thereby improving the service life of the partition 6.
[0033] Please see Figure 5 The positioning block 8 has spherical grooves at both its upper and lower ends, with ball bearings rotatably connected within these grooves. By using these grooves and ball bearings, the positioning block 8 can slide more smoothly within the through hole 7, making it easier for it to engage with the positioning groove 11 and thus improving the efficiency of technicians. A rotating groove 802 is cut at the end of the positioning block 8 near the screw 10, and a rotating block 1001 is fixedly connected to the end of the screw 10 near the positioning block 8. The rotating block 1001 matches the rotating groove 802. By setting the rotating block 1001 and... The rotating groove 802 ensures that the screw 10 and the positioning block 8 will not separate when they rotate relative to each other. As the screw 10 rotates into the connecting plate 9, it pushes the positioning block 8 through the through hole 7 and into the positioning groove 11, thus locking the position of the partition 6. The outer end of the screw 10 is fixedly connected with multiple evenly distributed anti-slip patches 1002. The surface of the anti-slip patches 1002 is engraved with anti-slip texture. By setting the anti-slip patches 1002, the technicians are less likely to slip when rotating the screw 10, thereby improving the work efficiency of the technicians.
[0034] When using this invention, technicians insert the partition 6 into the lifting block 5 and move the lifting block 5 and partition 6 upwards along the lifting bar 4. After selecting a suitable position, the technicians rotate the screw 10, causing the screw 10 to push the positioning block 8 through the through hole 7 and continue into the positioning groove 11, thereby locking the position of the partition 6. Then, the fungal culture dish to be induced is placed on the partition 6, and the ultraviolet irradiation lamp 3 is turned on to irradiate the culture dish on the partition 6. Finally, the two movable cabinet doors 2 are closed, thus starting the ultraviolet mutagenesis experiment on the fungus. Compared with the prior art, this invention can flexibly adjust the layout of the experimental space by adjusting the position of the lifting block on the lifting bar, thereby improving the space utilization rate.
[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
