Linkage mechanism acting in opposite directions synchronously

Abstract

A linkage mechanism acting in opposite directions synchronously disclosed in the invention comprises a driving part with an internal space and driven by an external power source; a first actuating part disposed in the internal space; and a second actuating part disposed in the internal space. When the first actuating part and the second actuating part are synchronously driven by the driving part, the first actuating part and the second actuating part are relatively displaced close to each other in opposite directions or away from each other in opposite directions. Thereby, with a linkage relationship between the first actuating part and the second actuating part that act in opposite directions, an efficacy of rapid displacement and actions can be achieved.

Description

BACKGROUND OF THE INVENTIONField of Invention[0001]The invention is related to a linkage mechanism, and more particularly to a linkage mechanism acting in opposite directions synchronously.Related Art[0002]Taiwan utility model patent “Single Motor Driven Lifting Table Leg Structure” of No. M590010 is taken as an example for argumentation, which discloses that the leg of the lifting table comprises an inner frame sleeved in an outer frame, and one end thereof is fixed on a base. The inner frame is equipped with a screw assembly, which is driven by a power device and drives the outer frame to displace relative to the inner frame, so that a table plate located above the table leg can ascend and descend. However, because a stroke of the screw assembly for driving the outer frame to displace is very long and the stroke feed is very slow, it takes a long time to drive the table plate to ascend or descend, resulting in the problem of being unable to ascend and descend rapidly and to move q...

AI Technical Summary

Benefits of technology

The invention provides a linkage mechanism that works in opposite directions at the same time. This is achieved by using a linkage relationship between two actuating parts that act in opposite directions. As a result, the invention allows for faster displacement and actions. The second actuating part includes a second rod and a second connecting member that allows for sliding displacement of the second rod relative to the first rod. This further improves the stability of the connection and the relationship of actions between the two rods.

Problems solved by technology

However, because a stroke of the screw assembly for driving the outer frame to displace is very long and the stroke feed is very slow, it takes a long time to drive the table plate to ascend or descend, resulting in the problem of being unable to ascend and descend rapidly and to move quickly.
