Digital microscope tube automatic slide down maintenance method
If the digital microscope is used improperly, the focusing mechanism will loosen and the lens barrel will automatically slide down. The solution to this problem is as follows: (This maintenance method can help you quickly repair the microscope)
1 Lighter handling of downturns
Hold each hand tightly with a coarse quasi-focus spiral (fine adjustment hand wheel), hold your left hand tightly, and tighten the coarse focus screw clockwise with your right hand, and the situation will improve (be careful not to use too much force).
2 How to deal with serious downturns
Place the digital microscope on the table with the arm facing you, turn the barrel up to the highest position, and then slowly pull the lens barrel upwards until it is unplugged. Then hold a coarse quasi-focus spiral with both hands, hold the left hand tightly, and hold the other coarse focal screw in the right hand and rotate it counterclockwise until it is removed (the left coarse quasi-focus spiral is integral with the axis of rotation). , and then the left hand grips the coarse quasi-focus cock spiral together with the rotating shaft and draws out. After extracting, it will be found that the upward and downward movement of the lens barrel is controlled by the gear on the shaft and the gear on the lens barrel to control, and the focusing mechanism is too loose to cause the mirror The automatic sliding of the cylinder is caused by the small friction between the shaft and the sleeve. There is grease lubrication between the shaft and the sleeve.
Due to the large amount of use, the amount of butter is reduced, and the shaft is also subjected to a certain amount of wear and thinning. If only adding butter does not solve the problem, the author's approach is to take a thin and tough line (such as a construction line or shoe repair line) to divide it into very thin, many strands, but the whole is still one.
One end of this wire divided into many turns is made into a thin knot on the right end of the shaft, and the remaining wire is wound around the shaft. If it is not easy to get caught, you can apply some butter on the wire first. Too much of the line to prevent the shaft from getting too thick to get into the sleeve. Apply a layer of butter to the shaft of the tangled wire, put it in the sleeve, and install the coarse quasi-focus screw and the lens barrel. The digital microscope can then be used normally.
This method is also applicable to other optical microscopes such as fluorescence microscopes, stereo microscopes, biological microscopes, and the like.
