Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1-4, a drawing table for machine design and manufacture includes a support plate 7, a support frame 1 and a drawing board 6, wherein the support frame 1 is fixedly mounted at the bottom of the support plate 7, the drawing board 6 is hinged on the support plate 7 through a hinge 4, and the drawing board 6 can rotate relative to the support plate 7; a worm 9 and a worm wheel 15 are rotatably arranged on the carrier plate 7, the worm wheel 15 and the worm 9 are engaged with each other and can realize relative self-locking; a gear 10 is fixedly linked on the rotation center of the worm wheel 15, an adjusting rod 8 is meshed on the gear 10, one end of the adjusting rod 8 is rotatably installed on the drawing board 6, the worm 9 is further rotated to drive the worm wheel 15 to rotate, the worm wheel 15 is further rotated to drive the gear 10 to drive the adjusting rod 8 to move, and further angle adjustment between the drawing board 6 and the support board 7 is further realized under the pushing action of the adjusting rod 8; thereby greatly facilitating the drawing operation of different people; the worm 9 is fixedly connected with a connecting rod 11, the other end of the connecting rod 11 is fixedly provided with a knob 3, and the rotation of the worm 9 is further driven by rotating the knob 3.

Furthermore, the adjusting rods 8 are arranged in an arc shape, and the radius center of the arc shape is superposed with the rotation center of the hinge 4; thereby making the drawing protection board 6 more fluent when rotated.
