Background
The rapidly developed visual optical instrument is being rapidly applied to various fields such as industry, agriculture, medicine, military and the like, and gradually becomes an essential part in the life of people. In general, most of eyepiece systems are used to change the focal position of an eyepiece optical system by pulling or rotating the eyepiece frame (for example, chinese patent CN211528798U), so that the photosensitive surface of the display screen coincides with the focal plane of the eyepiece optical system. The former mode of focusing through pull eyepiece picture frame has advantages such as simple structure, convenient operation, but poor stability, interference killing feature are weak, lead to the image fuzzy because of outside touching very easily. The latter method of zooming by rotating the lens frame has a simple structure, but is inconvenient because the eyepiece cover rotates along with the lens frame during rotation. In addition, no matter the first drawing type or the second rotating type, the related equipment has the problems of poor sealing performance and the like, and can hardly be used in the environments of heavy fog, heavy rain, moist heat and the like. Therefore, it is very important to develop a new type of translation lens type focusing waterproof eyepiece.

Detailed Description
In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following description is further provided with reference to the specific embodiments and the accompanying drawings.
The translation lens type focusing waterproof eyepiece shown in the attached drawings 1-6 mainly comprises an eyepiece cemented lens 1, an eyepiece first lens 2, an eyepiece second lens 3, an eyepiece clamping ring 4, an eyepiece first spacer ring 5, an eyepiece second spacer ring 6, an eyepiece barrel 7, an eyepiece limit screw 8, an eyepiece seat 9, an eyepiece handwheel 10, an eyepiece handwheel clamping ring 11, an eyepiece cover 12, an eyepiece cover clamping ring 13, an OLED display screen 14, a sealing ring I15, a sealing ring II 16 and a sealing ring III 17. The eyepiece mount 9 is an assembly main body, and is kept stationary during focusing, and other parts are directly or indirectly fixed on the eyepiece mount 9.
As can be seen from fig. 1, the eyepiece cemented lens 1 is formed by combining 1 convex lens and 1 concave lens, the eyepiece first lens 2 is 1 convex lens, and the eyepiece second lens 3 is 1 convex lens. An eyepiece first spacer 5 and an eyepiece second spacer 6 are respectively arranged between the eyepiece second lens 3 and the eyepiece cemented lens 1 and between the eyepiece cemented lens 1 and the eyepiece first lens 2, a right-angle step-shaped eyepiece pressing ring 4 is arranged on the left side of the eyepiece second lens 3, and the right side of the eyepiece first lens 2 is pressed on the right-angle step inside the eyepiece sleeve 7, so that the three lenses are locked and sealed in the eyepiece sleeve 7 to form the eyepiece sleeve assembly. The eyepiece barrel assembly is coaxially sleeved in an eyepiece base 9 from right to left, a part of the eyepiece barrel assembly is left outside, an eyepiece hand wheel 10 is sleeved outside the eyepiece base 9, and the eyepiece hand wheel 10 is connected and driven with the eyepiece base 9 through multi-thread (coated with lubricating grease). The right end (end B) of the eyepiece handwheel 10 extends outwards to sleeve the eyepiece barrel 7, and is connected with the eyepiece barrel 7 through a clamping structure (a circle part, a step and an eyepiece handwheel pressing ring 11) at the right end to realize linkage. An OLED display screen 14 is hermetically connected to the side surface (A end) of the eyepiece base 9.
When the eyepiece hand wheel 10 is rotated, the eyepiece base 9 is not moved, and because the tail part (the part of the black oval circle in the figure 1) of the eyepiece hand wheel 10 is clamped by the eyepiece barrel 7 and the eyepiece hand wheel pressing ring 11 left and right, the eyepiece hand wheel 10 can only rotate spirally left or right under the action of the thread, and the eyepiece barrel 7 and the lenses inside the eyepiece barrel can not be driven to synchronously move left and right in parallel along with the rotation, so that the parallax compensation can be conveniently and quickly carried out. When the eyepiece barrel 7 is translated to the position where the eyepiece barrel reaches the maximum position (namely the edge of the limiting groove on the surface of the eyepiece barrel 7) when the eyepiece barrel is contacted with the eyepiece limiting screw 8, the eyepiece hand wheel 10 cannot be continuously rotated along the original direction at the moment, and only can be rotated in the opposite direction.
In order to ensure the waterproof, dustproof and sealing effects, the following multiple sealing measures are also adopted: 1. a sealant is coated at the joint of the eyepiece barrel 7 and the first eyepiece lens 2; 2. the eyepiece pressing ring 4, the eyepiece first spacer ring 5 and the eyepiece second spacer ring 6 are adopted in the lens barrel to fix and seal each lens, so that dust is prevented from entering the inside of the eyepiece; 3. the inner surface of the eyepiece handwheel 10 is in clearance fit with the outer surface of the eyepiece base 9 and the outer surface of the eyepiece barrel 7, and sealing rings with different specifications are fixedly arranged between the eyepiece base 9 and the connecting surface of the display screen of the external equipment.
The translation lens type focusing waterproof eyepiece is designed and produced, and the waterproof performance of a detected sample reaches the IP6 level.
