Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical instrument technology, and more specifically, to a protective structure for optical instruments. Background Technology
[0002] Optical instruments are composed of one or more optical devices. They are mainly divided into two categories: one is optical instruments that form real images, such as slide projectors and cameras; the other is optical instruments that form virtual images, such as telescopes, microscopes, and magnifying glasses. Because most optical instruments are precision instruments, they cannot be subjected to external impacts, otherwise it will affect their detection accuracy during use.
[0003] However, most traditional optical instruments do not have protective structures, which means that they cannot be protected after use, making them susceptible to damage from falling objects or other factors.
[0004] Furthermore, its moisture-proof performance is poor. If the instrument comes into contact with liquid and is left untreated for an extended period of time, it is prone to mold growth, which will affect its subsequent use. Utility Model Content

[0033] More specifically, the user can rotate the bevel gear 8 by turning the rocker arm 7. The bevel gear 8 will then drive the lead screw 6 to rotate, causing the lifting plate 2 to lower the instrument body 3 and allow it to enter the protective shell 1 for protection, reducing the impact of dust. After the instrument body 3 enters the protective shell 1, the two opening and closing covers 9 can be moved and closed by the cooperation of the guide post 12 and the strip hole 11, thereby shielding and protecting the upper part of the instrument body 3 for better protection. Finally, the connecting plate 15 is sleeved on the outer end of the threaded post 14 and fixed by the clamping nut 16 to secure the two opening and closing covers 9 for easy use.
[0034] Please see Figures 3-6 As an embodiment for drying the instrument body 3: a vent 17 is provided on the lower end face of the protective shell 1 at the middle position. A frame 18 is fixedly provided on the outer end of the vent 17 at the lower end face of the protective shell 1. A mounting groove 19 is provided on both sides of the inner wall of the frame 18.

[0035] Specifically, when the instrument body 3 enters the interior of the protective shell 1, the heat lamp 21 can be turned on to gradually increase the temperature inside the protective shell 1 to dry the instrument body 3 and prevent it from getting damp. In addition, by setting the vent 17, the interior of the protective shell 1 can be kept ventilated to prevent the air pressure from rising and causing damage to the instrument body 3, which would affect its normal use later.
[0036] Please refer to Figure 1 As a further embodiment to keep the bottom of the device breathable: pads 24 are fixedly provided on the lower end face of the protective shell 1 and on both sides.
[0037] Specifically, the pad 24 can support the protective shell 1 to ensure air circulation at its bottom, thereby keeping the interior of the protective shell 1 ventilated, increasing drying efficiency, and preventing the instrument body 3 from getting damp.
[0038] In summary, when using the entire device: the user can rotate the rocker arm 7 to rotate the bevel gear 8, which in turn drives the lead screw 6 to rotate, causing the lifting plate 2 to lower the instrument body 3 into the protective shell 1 for protection. Then, the guide post 12 and the strip hole 11 work together to move the two opening and closing covers 9 to close them, thereby shielding and protecting the upper part of the instrument body 3 for better protection.
