The embodiment of the application discloses a marine plotter. As shown in fig. 1, a marine plotter, including drawing set-square 1, the hypotenuse department of drawing set-square 1 is equipped with the horizontal ruler 2 that is on a parallel with 1 hypotenuse of drawing set-square, the surface of horizontal ruler 2 rotates jointly with the surface of drawing set-square 1 and is connected with two dwang 11, the rotation plane of dwang 11 is on a parallel with the surface of drawing set-square 1 and horizontal ruler 2, dwang 11 will promote horizontal ruler 2 and be close to or keep away from drawing set-square 1 in rotatory in-process, so drawing set-square 1 and horizontal ruler 2 will constitute the parallel ruler jointly, the combination that has realized drawing set-square 1 and parallel ruler uses.

As shown in fig. 2 to 4, the back of horizontal ruler 2 is connected with slider 21 along self length direction slides, slider 21 rotates through pivot 22 and is connected with vertical ruler 3, the rotation plane of vertical ruler 3 is on a parallel with the surface of horizontal ruler 2, vertical ruler 3 can rotate the horizontal ruler 2 of perpendicular to, horizontal ruler 2 and vertical ruler 3 will constitute the T square jointly this moment, thereby realized drawing set square 1, parallel ruler and T square three's combined use, made things convenient for marine graphics primitive's carrying and use.

The set square 1 and the horizontal ruler 2 of drawing all bond on the surface and are fixed with magnet piece 24, through the rotation of self when dwang 11 for horizontal ruler 2 moves and laminates in the hypotenuse of the set square 1 of drawing, this moment horizontal ruler 2 will adsorb each other fixedly with the magnet piece 24 on the set square 1 of drawing, make horizontal ruler 2 stably accomodate on the set square 1 of drawing, in order to avoid horizontal ruler 2 and the condition that takes place to scatter when the set square 1 of drawing need not to use.

It is worth noting that two magnet blocks 24 are provided on both the lateral straightedge 2 and the drawing cam 1, thereby improving the stability of the lateral straightedge 2 on the drawing cam 1.

As shown in fig. 1 and 2, the surface of the horizontal ruler 2 is connected with an illuminating lamp 26 through a mounting column 25, and the illuminating lamp 26 can face the drawing set square 1, the horizontal ruler 2 and the vertical ruler 3, so that a worker can normally read the numerical values on the drawing set square 1, the parallel ruler and the T-square under the dark condition.

The illuminating lamp 26 is connected with a plug 262 through a wire 261, and the plug 262 can be plugged into an external power supply, so that the illuminating lamp 26 is powered on; wire 261 spiral winding installs elasticity card ball 263 on the wire 261 on the erection column 25, be equipped with the joint groove 251 that supplies elasticity card ball 263 card to go into on the lateral wall of erection column 25, when the wire 261 need not to use, the wire 261 with the spiral winding on the erection column 25, elasticity card ball 263 with the joint in joint groove 251 for the wire 261 is by spacing fixed and difficult in disorder, has realized accomodating the stability of wire 261.

As shown in fig. 3 and 4, the back of the transverse straight scale 2 is provided with a dovetail groove 27 extending along the length direction of the transverse straight scale 2, and the slide block 21 is arranged in a dovetail shape and is embedded in the dovetail groove 27 in a sliding manner, so that the slide block 21 is connected with the transverse straight scale 2 in a sliding manner; the dovetail groove 27 penetrates through one end of the transverse straight edge 2, so that the slider 21 can be conveniently assembled and disassembled on the transverse straight edge 2.

The back bonding of horizontal ruler 2 is fixed with two limiting plates 28, one side that two limiting plates 28 are relative has enclosed into the storage area 281 that supplies vertical ruler 3 to slide to inlay to establish jointly with the back of horizontal ruler 2, when vertical ruler 3 need not to use, vertical ruler 3 can revolute 22 rotatory parallel to horizontal ruler 2, vertical ruler 3 slidable is embedded into in the storage area 281 this moment, make vertical ruler 3 be difficult for influencing the use of drawing set-square 1 and parallel ruler, and made things convenient for accomodating of plotter to carry.

One end of the transverse straight scale 2 penetrated by the dovetail groove 27 is in threaded fit with a blocking bolt 29, the tail part of the blocking bolt 29 can be rotatably embedded into the dovetail groove 27, and when the longitudinal straight scale 3 is stored in the storage area 281, the blocking bolt 29 can block the sliding block 21 from being separated from the dovetail groove 27, so that the stability of the longitudinal straight scale 3 in the storage area 281 is ensured.

A torsion spring 23 is wound on the rotating shaft 22, and two ends of the torsion spring 23 are respectively connected to the longitudinal straight edge 3 and the sliding block 21. When the longitudinal straightedge 3 is stored in the storage area 281, the torsion spring 23 will be in a deformed state, so that the longitudinal straightedge 3 abuts against one of the limiting plates 28, thereby improving the stability of the longitudinal straightedge 3 in the storage area 281.

When the slide block 21 slides to the end of the dovetail groove 27 far away from the blocking bolt 29, the longitudinal straight edge 3 will slide to be separated from the receiving area 281, and at this time, the torsion spring 23 will gradually return to the natural state, so that the longitudinal straight edge 3 is turned over to be perpendicular to the transverse straight edge 2, and the longitudinal straight edge 3 and the transverse straight edge 2 will jointly form a t-square for the navigation drawing work.

The implementation principle of the marine plotter in the embodiment of the application is as follows: when the drawing set square 1 is needed, a worker can directly use the drawing set square 1 in the drawing instrument; when the parallel ruler is needed, a worker rotates the rotating rod 11, and the rotating rod 11 pushes the transverse straight ruler 2 to be far away from the drawing set square 1 in the rotating process, so that the drawing set square 1 and the transverse straight ruler 2 jointly form the parallel ruler; when needs use the T chi, the workman breaks away from in storage area 281 with vertical ruler 3 pulling, and torsional spring 23 will reply to natural state gradually for vertical ruler 3 upset perpendicular to horizontal ruler 2, vertical ruler 3 will constitute the T chi jointly with horizontal ruler 2.

This application will draw set square 1, parallel ruler and T square three and combine to use together for drawing tool is difficult for losing or seeks inconvenience, has made things convenient for marine drawing tool's carrying and use.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
