Embodiment

[0024] see figure 1 and figure 2 , an integrated track meter plotting device, comprising a housing 1, a pen 2 and a pen lifting structure 3. The brush lift-off structure 3 includes an armature 31 and a coil 32 . The armature 31 is in the shape of a strip, and a limiting block 311 is fixed at one end of the armature 31 . During specific implementation, threaded holes are provided on the limit block 311, and an external thread is provided on the fixed end of the armature 31 and the limit block 311. The threaded fixing between the limit block 311 and the armature 31 is convenient for installation and disassembly. Bit block 311. Preferably, the limiting block 311 is a round iron block, and the round iron block is easy to obtain, which is convenient for controlling the manufacturing cost. The other end of the armature 31 passes through the housing 1 and expands to form an enlarged end 312 , so that the armature 31 and the limiting block 311 form an "I" shape as a whole. In th...

Abstract

The invention discloses an integrated plotting device for a track plotter. The integrated plotting device comprises a shell body, a plotting pen and a plotting pen lifting structure, wherein the plotting pen lifting structure comprises an armature and a coil; the armature is strip-shaped, a limit block is fixed to one end of the armature, and the other end of the armature penetrates through the shell body and then is expanded to form an expanded end, so that the armature and the limit block are I-shaped as a whole; the coil is located in the shell body, and sleeves the armature; a return spring is arranged between the limit block and the shell body, and sleeves the armature, and the two ends of the return spring are connected with the limit block and the shell body separately; and the plotting pen is fixed to the expanded end of the armature. The structure of the plotting device for the track plotter can be simplified, and direct control over the plotting pen is realized, so that the control accuracy for the plotting pen is improved.

Description

technical field [0001] The invention relates to the field of navigation, in particular to an integrated track meter drawing device. Background technique [0002] The track meter is one of the main supporting equipment in the navigation system of ships and warships. It can automatically and continuously display the navigation information on the chart according to the course and distance information provided by the gyro compass and the log, or the positioning information provided by other navigation equipment. Draw the track and mark of the ship's navigation, so that the navigator can intuitively understand the current position, the degree of deviation and the safety degree of the future sea area. It plays a very important role for ships and warships to sail in the sea. [0003] The existing track meter drawing device controls the falling and lifting of the paint pen through lever control. Specifically, the painting pen is connected to one end of the lever, and the other end...
