Technical Field
[0001] This utility model relates to an image observation device, and more particularly to an observation device with an ergonomic tilt mechanism, belonging to the field of microscope technology. Background Technology
[0002] A microscope is an instrument primarily used to magnify tiny objects visible to the naked eye. The eyepiece is a visual optical device used to observe the image formed by the optical system in front, and is a component of visual optical instruments such as telescopes and microscopes. It further magnifies the real image obtained by the objective lens for observation. However, in conventional microscopes, the eyepiece tube is fixed to the microscope head shell. When people of different heights observe, the eyepiece tube cannot be adjusted up or down to change the observation angle, which is very inconvenient for observing the image. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing image observation devices, where the eyepiece tube is fixedly connected to the observation head, the observation head can rotate 360°, but the eyepiece tube cannot be adjusted up and down, which makes it inconvenient to observe the image. This invention provides an observation device with an ergonomic tilt mechanism, which allows the eyepiece tube to be connected to the observation head with an adjustable tilt angle, thus facilitating the observation of the image.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an observation device with an ergonomic pitch mechanism, comprising an eyepiece tube for mounting an eyepiece; further comprising a reflector A, a reflector B, a reflector frame A, a reflector frame B, a reducer base, a prism reflecting hole, a right bracket, a gear frame, an eyepiece tube connector, a drive gear, a transmission gear, a long shaft, short shaft A, short shaft B, short shaft C, driven gear A, and driven gear B; the reflector frame A is disposed at the rear of the reducer base; the reflector A is disposed on the reflector frame A;
[0005] The eyepiece tube connector is an integral structure, including an eyepiece tube connector body, a left curved arm, and a right curved arm. The left curved arm includes a short side A and a long side A perpendicular to each other. The right end of the short side A is fixedly connected to the left end of the eyepiece tube connector body, and the long side A is vertically downward. The right curved arm includes a short side B and a long side B perpendicular to each other. The left end of the short side B is fixedly connected to the right end of the eyepiece tube connector body, and the long side B is vertically downward. The long side A of the left curved arm and the long side B of the right curved arm are parallel to each other. Each of the lower ends of the left and right curved arms has a through hole.
[0006] The reflector frame B includes a left frame, a right frame, and a short shaft D; the left and right frames are located at the front of the reducer base, and the reflector B is located between the left and right frames; the left frame has a through hole A, and the right frame has a through hole B; the gear frame has a through hole C at the rear and a through hole D at the front; the right support has a through hole E at the front and a through hole F at the rear; a prism reflecting hole is located on the reducer base in the middle of the reflector frame A, and a micro-adjustment spring mounting hole is located in the middle of the reducer base in front of the prism reflecting hole;
[0007] The right side of the short shaft B is inserted into the through hole of the left curved arm and fastened, and the drive gear is sleeved on the left side of the short shaft B and fastened; when the eyepiece tube tilts up and down, it drives the short shaft B and the drive gear to rotate.
[0008] The long shaft is rotatably connected through holes C and F in the middle. The transmission gear is tightly connected to the left end of the long shaft and the left side of the gear carrier. The driven gear A is tightly fitted onto the long shaft through its central hole and is located on the right side of the gear carrier. When the driving gear meshes with the transmission gear and transmits power to the transmission gear through the action of force, it also drives the long shaft and the driven gear A to rotate.
[0009] The right curved arm passes through the middle of the short shaft C and is fastened. The left end of the short shaft C is inserted into the through hole E of the right bracket and is rotatably connected.
[0010] The short shaft A is inserted through the center hole of the driven gear B and is fastened thereto. The left end of the short shaft A is inserted into the through hole D of the gear carrier and is rotatably connected. The right end of the short shaft A passes through the through hole A to the right and is rotatably connected to the through hole A. After that, the right end face of the short shaft A is fastened to the middle of the left side of the reflector B. The short shaft D passes through the through hole B to the left and is rotatably connected to the through hole B. After that, the left end face of the short shaft D is fastened to the middle of the right side of the reflector B.
[0011] It also includes a stainless steel washer, an elastic washer, and a tension adjustment ring. The stainless steel washer, the elastic washer, and the tension adjustment ring are fitted from left to right on the right end of the short shaft C and press tightly against the lower end of the long side of the right bent arm to the left. The tension adjustment ring is tightly fitted with the short shaft C and is turned to adjust the tightness of the right bent arm.
[0012] The specimen imaging uses the principle of optical reflection. The light is transmitted through the prism reflection hole to the reflector A, then reflected by the reflector A to the reflector B, and finally reflected by the reflector B to the eyepiece.
[0013] It also includes a micro-adjustment spring and a spring cap. The lower half of the micro-adjustment spring is disposed in the micro-adjustment spring mounting hole, and its upper half extends upward. The spring cap is sleeved on the micro-adjustment spring, and the upper end of the spring cap rests on the lower surface of the reflector B. When the eyepiece tube is tilted to the appropriate desired angle, it is necessary to maintain and stabilize this angle to prevent changes in angle. Therefore, the micro-adjustment spring can play a role in preventing rotation, making the eyepiece more stable during observation.
[0014] It also includes a rotating ring and a pressure cap, which are disposed below the reducer base and around the prism reflection aperture. The rotating ring and pressure cap are used to fix the device to the microscope main unit.
[0015] It also includes a speed reducer cover and an eyepiece tube pitch cover. The speed reducer cover is located above the speed reducer base, and the eyepiece tube pitch cover is located in front of the speed reducer cover. The eyepiece tube passes through the middle of the eyepiece tube pitch cover.
[0016] Operating principle: When the eyepiece tube tilts up or down, the left curved arm drives the short shaft B and the drive gear to rotate; the drive gear meshes with the transmission gear, and the drive gear drives the transmission gear to rotate, which in turn drives the long shaft and the driven gear A to rotate; the driven gear A meshes with the driven gear B, and the driven gear A drives the driven gear B to rotate, which in turn drives the short shaft A to rotate, and the short shaft A drives the reflector B to rotate with the central shaft, thus realizing the long-distance transmission of power and ensuring that light is always transmitted from the prism reflection hole to the reflector A, then reflected to the reflector B, and finally reflected to the eyepiece.
