Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical lens detection, in particular to a compressive strength test device for optical lenses. Background Art
[0002] When optical lenses are used in glasses, telescopes, microscopes and camera lenses, they may face unexpected pressure shocks, so it is necessary to conduct compressive strength tests on optical lenses. This is mainly to determine the maximum load that the lens material can withstand without breaking when subjected to external pressure. This experiment is of great significance for evaluating the mechanical strength and tolerance of lens materials.
[0003] The existing optical lens compressive strength test device usually requires placing the optical lens on an inspection table, and then controlling the lower pressure plate through a loading device to pressurize the optical lens, so as to test the compressive strength of the optical lens. However, the existing device has a high cost and high energy consumption when performing pressure testing, and the operation is relatively complicated.
[0004] Therefore, in order to solve the above problems, an optical lens compressive strength test device has been developed which can reduce test costs, reduce energy consumption, has high simplicity and flexibility, and is relatively easy to operate. Utility Model Content

[0006] The technical scheme is as follows: An optical lens compressive strength test device comprises a connecting frame, an inspection table, a display screen, a limit assembly, a fixed hollow column, a pressure column, a reset spring, a first one-way valve, a connecting pipe, a squeezing ball, a second one-way valve and an exhaust assembly.

Under the action of the first one-way valve and the second one-way valve, the squeezing ball is pressed to allow air to enter the fixed hollow column through the connecting pipe, thereby squeezing the pressure column, so that the pressure column slides downward to pressurize the optical lens on the inspection table, and the pressure value is displayed on the display screen.
[0007] More preferably, the limiting assembly includes a guide fixing frame and a compression spring. The lower part of the connecting frame is symmetrically and slidingly connected to the guide fixing frame. The guide fixing frame is connected to the connecting frame with a compression spring. The guide fixing frame is pulled to slide toward the side away from each other, and the compression spring is compressed. The optical lens is placed on the inspection table. Under the action of the compression spring, the guide fixing frame is driven to slide toward the side close to each other to squeeze and limit the optical lens.
[0008] More preferably, the guide fixing frame is provided with a knob to facilitate pulling the guide fixing frame to slide.
[0009] More preferably, adjacent sides of the guide fixing frame are both arc-shaped structures.
[0010] More preferably, the exhaust assembly includes an exhaust pipe and a valve, the exhaust pipe is connected to the upper front side of the fixed hollow column, and the valve is rotatably connected to the exhaust pipe. After the experiment is completed, the valve is rotated to allow the air in the fixed hollow column to be discharged through the exhaust pipe, thereby completing the pressure relief operation.
[0011] More preferably, an anti-slip groove is provided on the valve.
[0012] The beneficial effects are: 1. The utility model presses the squeezing ball to allow air to enter the fixed hollow column through the connecting tube, thereby squeezing the pressure column, causing the pressure column to slide downward to pressurize the optical lens on the inspection table, which can reduce testing costs, reduce energy consumption, has high simplicity and flexibility, and is relatively easy to operate.
[0013] 2. The utility model pulls the guide fixing frame to slide to the side away from each other, compresses the compression spring, and then places the optical lens on the inspection table. Under the action of the compression spring, the guide fixing frame is driven to slide and reset to the side close to each other, thereby achieving the effect of clamping and limiting the optical lens on the inspection table.
