Rocking handle type transmission device with spring

Abstract

The invention discloses a rocking handle type transmission device with a spring. The rocking handle type transmission device comprises a supporting seat (1), a transmission shaft (2), a crank shaft (3) and a bearing seat (4) located on the left side of the supporting seat (1); a rectangular groove (11) is formed in the right end face of the transmission shaft (2), and the crank shaft (3) is composed of a square head (9), a step shaft (10) and a square shaft (14) which are connected in sequence from right to left, wherein the square shaft (14) is matched with the rectangular groove (11); the square shaft (14) of the crack shaft (3) is located in a bearing hole (5) and sleeved with a spring (12), one end of the spring (12) is pressed on a check ring (7) in an abutted mode, the other end of the spring (12) is pressed on the square shaft (14) and the shoulder of the step shaft (10) in an abutted mode, and the square head (9) of the crank shaft (3) is located outside the supporting seat (1). The rocking handle type transmission device has the advantages that the structure is compact, it is guaranteed that under the situation that no electricity is provided, rising and falling of a platform are achieved, operation is simple, and when the device is not used, the square shaft can be automatically pulled out of the rectangular groove.

Description

technical field [0001] The invention relates to the technical field of a transmission device structure for a lifting meteorological antenna, in particular to a rocker type transmission device with a spring. Background technique [0002] In the technical field of meteorological monitoring, the meteorological antenna installed in the meteorological vehicle is usually used to detect weather changes in real time. When working, the meteorological antenna in the vehicle needs to be raised vertically from the vehicle, and the lifting mechanism for driving the meteorological antenna to rise The device mainly includes a motor, a reducer, a screw nut pair and a platform for installing a meteorological antenna. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to a vertically arranged screw rod. A nut is installed on the nut, and a horizontal platform is fixed on the nut. When the weather antenna is lifted, the moto...

Problems solved by technology

[0003] The weather vehicle operates in the field for a long time, and the battery alone is not enough to run the entire vehicle body, and there are often situations where the motor cannot be energized. In this emergency situation, the normal lifting of the weather station cannot be guaranteed, and there is no complete set of emergency measures
