Embodiment 1

[0024] refer to Figure 1-5 , a convenient drawing device for mechanical design, including a box body 1, two fixed rods 6 are fixedly installed on one side of the top of the box body 1, and the same drawing board 7 is installed rotating between the two fixed rods 6, the box body Two first screw mandrels 13 are rotatably installed on the top inner wall of 1, and the first gear 14 is fixedly sleeved on the two first screw mandrels 13 and the same movable plate 9 is threaded, and the bottom of the movable plate 9 is A vertical bar 3 is fixedly installed, and two fixed blocks 2 are fixedly installed on the inner wall of the bottom of the box body 1. There are movable holes between the two fixed blocks 2 and the box body 1, and the bottom ends of the two vertical bars 3 pass through The corresponding movable hole extends to the outside of the box body 1 and is fixedly equipped with two wheels 11. The top of the box body 1 is provided with a turning hole, and the first screw guide s...

Embodiment 2

[0026] In the present invention, the connecting gear 18 is fixedly sleeved on the first screw guide sleeve 19, and a first threaded hole is opened on one side of the box body 1, and the first threaded rod 16 is installed on the inner thread of the first threaded hole, and the first threaded rod 16 is installed on the first threaded hole. Both ends of the rod 16 extend to the outside of the first threaded hole and one end is rotatably equipped with a connecting rack 15 meshed with the connecting gear 18, and the other end is fixedly sleeved with a turntable 33, and the rotation of the turntable 33 drives the first threaded rod 16. The inward rotation of the first threaded rod 16 drives the inward movement of the connecting rack 15, and the connecting rack 15 drives the rotation of the connecting gear 18, the first screw guide sleeve 19, and the second gear 17.

[0027] In the present invention, the thread directions of the two first screw rods 13 are oppositely set, and two comp...

The convenient drawing device is simple in structure and convenient to use, is convenient to carry, can press and fix paper for drawing, and is convenient to use for drawing.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a convenient drawing device for mechanical design. Background technique [0002] Mechanical design is an important part of mechanical engineering, the first step in mechanical production, and the most important factor determining mechanical performance. The goal of mechanical design is to design the best machinery under various limited conditions (such as materials, processing capabilities, theoretical knowledge and calculation methods, etc.), that is, to make optimal designs. Optimal design needs to comprehensively consider many requirements, generally including: the best working performance, the lowest manufacturing cost, the smallest size and weight, the most reliable in use, the lowest consumption and the least environmental pollution. These requirements are often contradictory, and their relative importance varies with the type and application of the machinery. T...
