Description

Technical Field

[0001] The utility model belongs to the technical field of microscope equipment, and in particular relates to an anti-pull light source push-pull device. Background Art

[0002] Among various types of LED fluorescent light sources for microscopes, integrated integrated fluorescent modules are becoming more and more popular in the market due to their small space occupation and simple control operation. The integrated module assembles the illumination lamp beads that provide excitation light in a specific band, the fluorescent color filter group that selectively filters the light, and the circuit components that control the lamp bead switch and lighting intensity in a small housing, and the housing is assembled in the limited space under the microscope objective turntable to play a role. The user switches different fluorescent illumination modules by pushing and pulling the rod to achieve imaging of different signal markers on the sample.

[0003] At present, the integrated LED fluorescent modules on the market usually fix the circuit components on the shell, such as travel switches, potentiometers, etc., and the optical parts such as lighting lamp beads and color filter groups need to be connected and fixed with the push-pull rod. By controlling the movement of the push-pull rod, the lamp bead lighting module of a specific band can be moved to the light outlet and lit, so as to achieve specific excitation of the sample. Therefore, the operator can achieve imaging of different marker signals by controlling the push-pull rod at different positions. In this design, because one end of the control wire of the lamp bead needs to be connected to the circuit component, that is, it is fixed in a specific position, so during the movement of the push-pull rod, the control line will follow it to move in the shell, and in a shell, there are often three or even four groups of different lamp bead lighting units, and the internal lines will increase exponentially. In the process of pushing and pulling back and forth, the line is very easy to be pulled and disconnected, resulting in the lamp bead being unable to be lit or controlled normally.
