Description

Technical Field

[0001] This utility model relates to the field of precision optical instruments, and in particular to a microscope holder. Background Technology

[0002] The microscope stand is an important component of a microscope, mainly used to support and fix the microscope's arms, stage, focusing system, and other parts, ensuring the microscope's stability and operational flexibility.

[0003] Early systems employed traditional rigid support structures, using metals such as brass, cast iron, or wooden brackets. Height and angle were adjusted manually with screws, and stability depended on material strength and machining precision. Manual focusing mechanisms were used, employing gears, racks, or micrometers for coarse and fine focusing. These traditional methods had limitations: they were susceptible to vibration, had low adjustment accuracy, and were prone to wear and tear with prolonged use.

[0004] To address the problems existing in the background art, this utility model provides a microscope holder. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a microscope holder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A microscope holder includes a rear base, a front base, and a lens holder frame. The rear base and the front base are connected to each other. The lens holder frame is fixed to the outside of the front base. The holder also includes a helical gear shaft and a helical rack. The helical rack is vertically disposed in the front base. The helical gear shaft passes through the center of the rear base from the side and meshes with the helical rack. Handwheels are connected to both ends of the helical gear shaft. Rotating the handwheels drives the helical gear shaft to move vertically along the helical rack. The rear base moves vertically with the helical gear shaft.

[0008] Furthermore, the bottom surface of the helical rack is separated from the front base, and the front base is provided with locking posts, which engage with the two sides of the helical rack.

[0009] Furthermore, the distance between the bottom surface of the helical rack and the front base is 0.5mm.

[0010] Furthermore, damping slide bars are provided on both sides of the inner wall of the rear base.

[0011] Furthermore, vertical grooves are provided on both sides of the inner wall of the rear base, and the damping slide rod is engaged in the vertical grooves.

[0012] Furthermore, a connecting plate is provided on the rear side of the rear base, and the connecting component assembly is connected to the connecting plate.

[0013] Furthermore, the connecting assembly includes a connector base, a screw assembly, and a screw seat. One end of the screw seat passes through the circular hole of the connector base, the connecting base abuts against the connecting plate, and the screw assembly passes through the screw hole of the connecting plate and is fixedly connected to the screw hole of the screw seat.

[0014] Furthermore, the screw assembly includes a screw and a washer.

[0015] Furthermore, the helical gear shaft has threads at both ends, and the handwheel is fixedly connected to the two ends of the helical gear shaft via the threads.

[0016] Furthermore, the damping slide is a nylon damping slide, and the helical rack is a nylon helical rack.

[0017] The beneficial effects of this utility model are as follows: the progressive meshing of the helical rack and helical gear shaft makes the transmission process smooth, and automatically reduces the compensation gap to reduce backlash, improves adjustment accuracy, and can withstand greater loads and increase service life; the suspended structure of the gear rack increases the elastic space during transmission, making the transmission smoother.
