Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, and more specifically, to a moiré fringe popular science device. Background Technique

[0002] Technically speaking, moiré fringes are the visual result of interference between two lines or two objects at a constant angle and frequency. When the human eye cannot distinguish these two lines or two objects, only the interference pattern can be seen. The pattern in this optical phenomenon is the moiré fringe. Since the moiré fringe is an optical phenomenon and not easy to observe, demonstration equipment is needed during teaching for more intuitive teaching.

[0003] In the existing public technology, the application number is: CN201920954047.X, a moiré fringe popular science demonstration device, including a bottom box, an installation box and an installation frame. One side of the bottom box is inserted and connected with one end of an installation plug board. Two irradiation lamps are embedded at the top of the installation plug board. The top of the bottom box is fixedly connected with the bottom of the installation box, and the inside of the bottom box is communicated with the inside of the installation box. One side of the installation box is connected to the bottom figure. The top of the installation box is fixedly provided with an installation frame. A groove is opened in the middle of the installation frame. The bottom of the groove is communicated with the inside of the installation box, and side grooves are opened on both sides of the groove.

[0004] However, the above patent still has certain disadvantages in use: although it can enrich the overall popular science type by replacing the style of the bottom figure, when replacing the bottom figure, personnel need to open the installation box, and at this time, the internal structure of the installation box will be exposed, which increases the probability of damage to the bottom figure by external personnel, and then greatly reduces the use safety and service life of the device, and is not conducive to long-term use. The overall use effect is not very ideal.

[0005] In view of the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0029] According to an embodiment of the present utility model, a moiré fringe popular science device is provided.

[0030] Now, the present utility model will be further described in conjunction with the attached drawings and specific implementation manners. As Figures 1-4 shown, a moiré fringe popular science device according to an embodiment of the present utility model includes a popular science box 1 and an adjustment groove 4. On both sides of the interior of the popular science box 1, adjustment screws 5 are symmetrically installed. One end of the adjustment screw 5 penetrates through one side of the popular science box 1 and is connected to a knob 7. A moving plate 6 is sleeved on the outer periphery of the adjustment screw 5, and both ends of the moving plate 6 are slidably connected to the inner wall of the popular science box 1. An installation block 11 is rotatably connected between the moving plates 6. One end of the installation block 11 penetrates through one side of the moving plate 6 and is connected to an adjustment shaft 17. A number of groups of embedding grooves 13 are circumferentially formed on the surface of the installation block 11, and a bottom drawing 12 is clamped inside the embedding grooves 13. On the surface of one end of the adjustment shaft 17, insertion rods 19 are symmetrically slidably connected. The other end of the insertion rod 19 is welded to a pulling plate 16. A spring 18 is sleeved on the outer periphery of the insertion rod 19, and both ends of the spring 18 are fixedly connected to the surface of the pulling plate 16 and the surface of the adjustment shaft 17 respectively.

[0031] In one embodiment, a guiding groove 10 is formed at the top of the popular science box 1. A grating plate 9 is slidably connected inside the guiding groove 10. One end of the grating plate 9 penetrates through one side of the guiding groove 10 and is connected to a moving handle 8.

[0032] In one embodiment, a number of groups of limiting grooves 14 are evenly formed on one side surface of the popular science box 1. The setting of the limiting grooves 14 is to limit and fix the adjustment shaft 17, thereby ensuring the stability of the installation block 11.

[0033] In one embodiment, a sliding groove 15 for the movement of the adjustment shaft 17 is formed on one side surface of the popular science box 1. The setting of the sliding groove 15 is to facilitate the adjustment shaft 17 to move up and down under the movement of the installation block 11, thereby realizing the change of the bottom drawing 12 at different positions, enriching the pattern types of subsequent popular science, and improving the popular science effect.

[0034] In one embodiment, adjustment grooves 4 are symmetrically formed on both sides of the bottom end inside the popular science box 1. The setting of the adjustment grooves 4 is to facilitate the installation and adjustment of the irradiation plate 2.

[0035] In one embodiment, an irradiation plate 2 is slidably connected to the inner position of the adjustment groove 4, and a plurality of groups of lamp beads 3 are evenly installed at the top position of the irradiation plate 2.

[0036] In one embodiment, a groove for abutting the bottom map 12 against the grating plate 9 is provided at the top inner position of the science popularization box 1. The setting of the groove is to ensure that the bottom map 12 can abut against the surface position of the grating plate 9, thereby facilitating the subsequent movement of the grating plate 9, so as to realize the change of the pattern, and thus realize the popularization of moiré fringes.

[0037] In one embodiment, the size of the limiting groove 14 is the same as that of the insertion rod 19. The setting of the size is to ensure that the insertion rod 19 can be inserted into the limiting groove 14, thereby realizing the fixation of the adjustment shaft 17, and thus realizing the limitation of the adjusted mounting block 11, avoiding the movement of the mounting block 11 from affecting the popularization of moiré fringes.

[0038] Working principle: In the actual use process, the grating plate 9 can be moved by moving the handle 8, so that the grating plate 9 and the bottom map 12 below move relatively. At this time, the user can observe the change of the pattern, and thus can realize the popularization operation of moiré fringes. Then, the user can also drive the adjusting screw 5 by rotating the knobs 7 on both sides. Then, by rotating the adjusting screw 5, the moving plate 6 is moved downward. Next, the moving plate 6 will move the entire mounting block 11 downward. Then, the user can rotate the mounting block 11 by rotating the adjustment shaft 17, so that different types of bottom maps 12 at other different positions on the surface of the mounting block 11 face the position of the grating plate 9. Then, by reversing the adjusting screw 5, the mounting block 11 can be reset, so that the bottom map 12 fits with the grating plate 9, facilitating the subsequent formation of different pattern changes, thus enriching the overall popularization type and improving the popularization effect. And the adjustment of the bottom map 12 is realized inside the science popularization box 1 and will not be directly exposed outside. Therefore, the overall adjustment safety can be effectively improved, the structure damage can be avoided, and the service life can be extended. The whole device has the advantages of diversified popularization patterns, anti-destruction of pattern replacement, and good popularization effect.
