Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to an optical glass lens. Background Art

[0002] An optical glass lens is an optical element made of glass with a surface that is part of a sphere. As an optical element, the lens can focus light and form a real image or a virtual image. This is its most basic function. Real and virtual images are widely used in various optical instruments and equipment, and are widely used in equipment such as microscopes and telescopes.

[0003] When installing the lens, the staff usually installs the lens on the frame first, and then installs the frame on the microscope by means of threaded connection. In order to ensure the stable connection of the lens, the staff usually installs optical glue on the frame. Optical glue is a material specially used for bonding optical elements, and has the characteristics of high light transmittance, low scattering, and low refractive index. The optical glass lens can be firmly bonded to other optical elements or frames using optical glue, so as to achieve the effect of precise positioning and fixation. However, when the lens needs to be replaced, the staff needs to carbonize or soften the optical glue first, so as to facilitate the staff to remove the lens. When the staff removes the lens, a large amount of residual optical glue is easily attached to the inner wall of the frame, so that when the staff replaces the lens, the optical glue on the frame needs to be cleaned to ensure that the lens can be firmly installed on the frame after replacement. This is too troublesome, time-consuming and labor-intensive, and affects work efficiency. Therefore, the utility model is proposed to solve the above problems. Utility Model Content

[0024] It should be noted that a cross groove is provided on the upper surface of the turning handle, and the staff can use a tool to drive the turning handle to rotate, thereby driving the threaded rod 7 to rotate.

[0025] When the staff needs to replace the lens 3, the threaded rod 7 is rotated by rotating the handle, so that the threaded rod 7 is disengaged from the threaded groove on the upper surface of the bottom plate 2, so that the staff can take out the top plate 5, thereby releasing the limit of the top plate 5 on the upper surface of the lens 3, making it convenient for the staff to take out the lens 3 from the fixed tube 1, so as to replace the lens 3. After replacing the new lens 3, the top plate 5 is covered, and the handle is rotated to rotate the threaded rod 7, so that the threaded rod 7 can be connected with the thread on the inner wall of the threaded groove, so that the top plate 5 can limit the upper surface of the lens 3, thereby completing the replacement of the lens 3.

[0029] The rubber pad 10 is provided to protect the inner surfaces of the lens 3 on both sides, thereby preventing the surface of the lens 3 from being damaged due to the squeezing force when the top plate 5 is installed on the lens 3 .

[0030] The working principle of the above embodiment is as follows: when the staff needs to replace the lens 3, the threaded rod 7 is rotated by rotating the handle, so that the threaded rod 7 is disengaged from the threaded groove on the upper surface of the bottom plate 2, so that the staff can take out the top plate 5, thereby releasing the limit of the top plate 5 on the upper surface of the lens 3, making it convenient for the staff to take out the lens 3 from the fixed tube 1, so as to replace the lens 3. After replacing the new lens 3, the top plate 5 is covered, and the handle is rotated to rotate the threaded rod 7, so that the threaded rod 7 can be connected with the thread on the inner wall of the threaded groove, so that the top plate 5 can limit the upper surface of the lens 3, thereby completing the replacement of the lens 3, saving time and effort, and improving work efficiency.
