Abstract

The invention provides a transmission mechanism. The transmission mechanism comprises a frame body, a lead screw, a driving part, a nut block and a connecting plate. The lead screw is vertically arranged on the frame body, and the two ends of the lead screw are rotationally connected with the frame body. The driving part is connected with the lead screw and used for driving the lead screw to rotate. The nut block is in threaded connection with threads of the lead screw, a connecting groove with two closed ends is formed in the side direction of the nut block, and the direction of the connecting groove is perpendicular to the axis of the lead screw. One end of the connecting plate is inserted into the connecting groove in a clearance fit mode through a rotationally-connected linkage pin, and the other end of the connecting plate is connected with a component to be driven. The nut block on the lead screw vertically moves on the lead screw along with rotation of the lead screw, downward movement or upward movement is determined according to the rotation direction of the lead screw, the nut block moves to drive the connecting plate to move, and the structure of a vertical staggered shaft transmission mechanism is simplified. The invention further provides an experiment tank comprising the above transmission mechanism.

Description

technical field

[0001] The present application relates to the technical field of experimental equipment, more specifically, to a transmission mechanism. The present application also relates to an experimental tank comprising the above transmission mechanism. Background technique

[0002] Turbine and worm is a commonly used mechanical mechanism that transmits rotational motion between two vertically intersecting axes in space. It is characterized by large transmission ratio and low noise, but it also has disadvantages such as high manufacturing cost, heavy structure, and long processing cycle. Especially for When the output shaft is only required to swing within a certain range and the transmission ratio is not high, the use of a worm gear mechanism is a waste of cost. In particular, in application scenarios such as the end cover switch of experimental equipment such as experimental tanks, a vertically staggered shaft transmission mechanism with a simple structure and low co...
