Technical Field

[0001] The utility model relates to the technical field of crystal growth, in particular to a device for observing the crystal growth state. Background Art

[0002] A crystal is a structure in which a large number of microscopic material units (atoms, ions, molecules, etc.) are arranged in a certain regular order. Therefore, the arrangement rules and crystal morphology can be studied and judged from the size of the structural units. Crystals are very widely distributed. Among the solid crystal substances in nature, the vast majority are crystals. Gases, liquids, and amorphous substances can also be transformed into crystals under certain suitable conditions.

[0003] In the existing Chinese utility model patent "An Observation Device for Crystal Growth State" with the application number 201821275092.4, it is disclosed that "in this observation device for crystal growth state, by setting the observation cover 13, the high-power microscopic camera 15 can be fixedly connected to the observation cover 13 in advance through the threaded connection between the threaded pipe 16 and the fixing nut 17. And by setting the through holes 14 evenly distributed on the observation cover 13, the observation angle can be adjusted. By setting the electric push rod 2, the distance between the culture dish 7 and the high-power microscopic camera 15 can be adjusted, so that the observation effect is better and it is convenient for users to use." Among them, the way to adjust the observation angle of the high-power microscopic camera is to fix it on the through holes at different positions. Each adjustment requires removing and reinstalling the camera, which is rather troublesome. Summary of the Utility Model

[0027] Please refer to Figures 1-4 , the present invention provides a technical solution: a crystal growth state observation device, including an observation box 1, an observation cover 9 is arranged on the top of the observation box 1, an electric push rod 6 is fixedly installed in the observation box 1, the free end of the electric push rod 6 is fixedly connected with a tray 3, four groups of guide posts 4 passing through the tray 3 are fixedly connected to the bottom of the observation box 1, and the top ends of the guide posts 4 are fixedly connected to the inner wall of the observation box 1 through a fixed rod 2. A petri dish 7 is placed on the tray 3. By setting the electric push rod 6, the distance between the petri dish 7 and the high-power microscopic camera 8 can be adjusted, so that the observation effect is better and it is convenient for users to use.

[0028] Specifically, as Figure 1 and Figure 3As shown in the figure, a through groove 901 is provided in the middle of the observation cover 9. A hollow screw rod 10 passes through the through groove 901. A high-magnification microscopic camera 8 is fixedly connected to the bottom end of the hollow screw rod 10. One end of the cable 13 is electrically connected to the display screen 12. By setting the display screen 12, the observation process can be transmitted to the display screen 12 in the form of images, eliminating the need for operators to observe for a long time. Moreover, there is a preservation record and it can be viewed repeatedly to observe the growth state of the crystal. The other end passes through the hollow screw rod 10 and is electrically connected to the high-magnification microscopic camera 8. The top end of the hollow screw rod 10 is threadedly connected with a connecting rod 11 perpendicular to it. Both ends of the connecting rod 11 are fixedly connected with swing rods 15. The free end of one side swing rod 15 is rotatably connected to the bottom side of the observation cover 9. The other side of the observation cover 9 is fixedly connected with a T-shaped screw rod 17. The free end of the other side swing rod 15 is movably sleeved on the T-shaped screw rod 17. A nut 16 that abuts against the swing rod 15 is threadedly connected to the T-shaped screw rod 17. By setting the observation cover 9, the high-magnification microscopic camera 8 can be fixedly connected to the observation cover 9 through the hollow screw rod 10 by threading. After loosening the nut 16, rotating the swing rod 15 drives the connecting rod 11 and the high-magnification microscopic camera 8 connected to it to rotate on the observation cover 9. After adjusting to the appropriate angle, the nut 16 is tightened. The observation angle can be adjusted conveniently without repeatedly disassembling and assembling the camera, and the operation is convenient. The structure of this device is simple and compact. It not only facilitates the adjustment of the observation angle and distance, but also saves the crystal growth process in the form of images, which is convenient for users to use.

[0029] Specifically, as Figure 2 and Figure 4 shown, a clamping assembly 5 for fixing the culture dish 7 is provided on the tray 3. A number of limiting grooves 301 are provided on the tray 3. The clamping assembly 5 includes a cross rod 51, a guide rod 52, a spring 53 and a soft pad 54. The soft pad 54 is bonded to the inner side of the cross rod 51. The length of the guide rod 52 is greater than the length of the limiting groove 301. The cross rod 51 is slidably matched with the limiting groove 301. One end of the guide rod 52 is fixed to the bottom of the tray 3 through a fixed seat. The other end of the guide rod 52 passes through the cross rod 51. A spring 53 disposed between the fixed seat and the cross rod 51 is sleeved on the guide rod 52. Since the parameters of the four groups of springs 53 are the same, when the culture dish 7 is placed between the four groups of cross rods 51, the moving distances of the cross rods 51 are the same. Under the pressure of the spring 53, the culture dish 7 is centered and clamped. The cross rod 51 has a certain moving range in the limiting groove 301, which is suitable for clamping culture dishes 7 of different sizes, and has high versatility.

[0030] Specifically, as Figure 3 shown, sliding grooves 902 are provided on both sides of the through groove 901 at the top of the observation cover 9. A pulley 14 that is in rolling cooperation with the sliding grooves 902 is rotatably sleeved on the connecting rod 11, which plays a role in supporting the connecting rod 11 and improving the structural strength of the connecting rod 11 without affecting the movement of the connecting rod 11.

[0031] Working principle: When in use, first, when the culture dish 7 is placed between the four groups of cross bars 51, the moving distances of the cross bars 51 are the same. Under the pressure of the spring 53, the culture dish 7 is centered and clamped. Secondly, by setting the observation cover 9, the high-magnification microscopic camera 8 can be fixed to the observation cover 9 by threaded connection through the hollow screw rod 10 in advance. After loosening the nut 16, the swing rod 15 is rotated to drive the connecting rod 11 and the high-magnification microscopic camera 8 connected thereto to rotate on the observation cover 9. After adjusting to a suitable angle, the nut 16 is locked. The observation angle can be adjusted conveniently without repeatedly disassembling and assembling the camera, and the operation is convenient. At the same time, by setting the electric push rod 6, the distance between the culture dish 7 and the high-magnification microscopic camera 8 can be adjusted, so that the observation effect is better, which is convenient for the user to use. By setting the display screen 12, the observation process can be transmitted to the display screen 12 in the form of images, without the need for the operator to observe for a long time, and there is a preservation record, which can be viewed repeatedly to observe the growth state of the crystal. The structure of this device is simple and compact. It is not only convenient to adjust the observation angle and distance, but also saves the crystal growth process in the form of images, which is convenient for the user to use.
