Example Embodiment

[0042] Specific embodiment one:

[0043] Combine below Figure 1-11 To explain the present embodiment, the present invention relates to a line drawing device, more specifically a geometric line drawing device, including a round seat 1, a line drawing pen 2, a door frame 3, a spring sleeve rod 4, and a slide rail rod 5. With the block 6, the line drawing pen 2 is always perpendicular to the paper surface. Compared with the hand animation line, the brush will tilt irregularly with the hand. The line drawing method perpendicular to the paper surface of the present invention draws more uniform lines.

[0044] The line drawing pen 2 is vertically slidably connected to the round seat 1. The upper end of the round seat 1 is provided with a door frame 3, the spring sleeve rod 4 is vertically slidably connected to the upper end of the door frame 3, and the lower end of the spring sleeve rod 4 It is fixedly connected to the upper end of the line drawing pen 2. The spring sleeve rod 4 is cov...

Example Embodiment

[0045] Specific implementation manner two:

[0046] Combine below Figure 1-11 To illustrate this embodiment, the manner in which the spring sleeve rod 4 can be pulled to the upper end and fixed is as follows:

[0047] The upper end of the spring sleeve rod 4 is hingedly connected with a support rod 7, the upper end of the door-shaped frame 3 is provided with a clamping slot 8, and the lower end of the support rod 7 abuts on the clamping groove 8, so that the spring sleeve rod 4 is pulled to the upper end and fixed; 7 can be rotated at the upper end of the spring sleeve rod 4, when the lower end of the support rod 7 abuts on the slot 8, the spring sleeve rod 4 is pulled to the upper end and supported, and then the line drawing pen 2 is lifted and fixed; making the support rod When 7 leaves the card slot 8, the spring sleeve rod 4 moves downward due to the force of the compression spring, so that the line drawing pen 2 moves downward to contact the paper to draw lines.

Example Embodiment

[0049] Specific implementation manner three:

[0050] Combine below Figure 1-11 To illustrate this embodiment, the two seat blocks 6 are fixedly connected with a horizontal rod 9, the right end of the rectangular frame 10 is provided with a convex head 11 at the front and rear ends, and the two horizontal rods 9 are slidably connected to the two convex On the head 11, the forward or backward movement of the circular seat 1 is controlled by the front and rear translation bar 12. The left end of the front and rear translation bar 12 is slidably connected to the left end of the rectangular frame 10 through a sliding groove structure, and the circular seat 1 is slidably connected in the left and right directions. Translation bar 12 on. The two horizontal rods 9 can respectively slide left or right on the two convex heads 11, thereby driving the two seat blocks 6 and the two sliding rail rods 5 to slide left or right, thereby driving the circular seat 1 and the painting When the li...

Abstract

The invention relates to a line drawing device, in particular to a geometric line drawing device. The device comprises a round seat, a wire drawing pen, a door-shaped frame, a spring sleeve rod, sliding rail rods and seat blocks, wherein the line drawing pen is always perpendicular to the surface of paper, and compared with manual line drawing, a drawing pen can irregularly incline along with hands, lines drawn by the line drawing mode perpendicular to the surface of the paper is more uniform. The line drawing pen is vertically and slidably connected to the round seat, the door-shaped frame isarranged at the upper end of the round seat, the spring sleeve rod is vertically slidably connected to the upper end of the door-shaped frame, the lower end of the spring sleeve rod is fixedly connected to the upper end of the line drawing pen, a compression spring sleeves the spring sleeve rod, a stop block is arranged at the lower end of the spring sleeve rod, the compression spring is positioned between the stop block and the door-shaped frame, the two sliding rail rods are fixedly connected between the two seat blocks, the left end and the right end of the round seat are both provided with notches corresponding to the sliding rail rods, the round seat is slidably connected to the two sliding rail rods, and the spring sleeve rod can be pulled to the upper end and fixed.

Description

technical field [0001] The invention relates to a line drawing device, more specifically a geometric line drawing device. Background technique [0002] The application number is CN201720024021.6, which discloses a geometric line drawing tool for teaching. The utility model discloses a geometric line drawing tool for teaching, including a first ruler board and a second ruler board, both of which are rectangular. One end of the first ruler is provided with a square slot, one end of the second ruler is inserted into the square groove and can reciprocate in the square groove; the other end of the first ruler is provided with a through hole A, and the other end of the second ruler One end is provided with a through hole B; one end of the first ruler plate is provided with a square slot and a fixing hole is provided, and a screw for fastening between the first ruler plate and the second ruler plate is pierced in the fixing hole; A plurality of round holes are evenly opened on the...
