Positioning mechanism and its carrying system

technical field

The utility model provides a positioning mechanism and its bearing system, in particular to a positioning mechanism and its bearing system which utilizes connecting rods to convert horizontal motions into vertical motions to achieve the positioning function.

Background technique

In a traditional positioning mechanism, a positioning pin is usually used to pass through a body and a fixed end to create constraints, thereby restricting the relative movement between the body and the fixed end.

However, the traditional positioning pin is separated from the body and the fixed end, which means that the positioning pin, the body and the fixed end are three independent unit components. Therefore, the user first needs to push the body to slide relative to the fixed end, and then drive the positioning pin to pass through the body and the fixed end to generate interference when the body slides to a preset position relative to the fixed end. Therefore, the user needs to perform relatively complicated steps to complete the installation and removal of the positioning pin, which makes the operation of the traditional positioning mechanism more inconvenient.
