Led mounting base, adjustment mechanism with led mounting base and red dot sighting device with adjustment mechanism

Abstract

An LED mounting base, an adjustment mechanism with the LED mounting base and a red dot sighting device with the adjustment mechanism are provided in the present disclosure. The LED mounting base includes a sliding block base and a pedestal in which an LED chip is mounted at the middle of the front end surface thereof. A sliding slot parallel to the length direction of the pedestal is disposed on the front end surface of the sliding block base. One end of the sliding slot is a blind end, and the other end of the sliding slot is an open end. After the pedestal being disposed in the sliding slot, the front end surface of the pedestal is parallel to the front end surface of the sliding block base. The LED mounting base which is modular in design and more compact, is less affected by the gap. The resultant force generated when adjusted in the two-dimensional directions of up and down as well as the left and right is decomposed into a single direction. The increase of the frictional force caused by the resultant force of the spring force in different directions is eliminated, and the precision difference and the interference phenomenon of the adjustment mechanism due to parts gap caused by the tolerance transmission between the parts are eliminated. There is no skew or stagnation phenomenon caused by the adjustment in two directions. The processing difficulty of the parts is reduced, and the production efficiency is improved.
