[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figures 1 to 3 As shown, an embodiment of the present invention provides a line drawing device, comprising a base frame 10, two support assemblies 20, and a line drawing assembly 30. The two support assemblies 20 are spaced apart along the extension direction of the base frame 10 and are capable of sliding along the extension direction of the base frame 10. The support assemblies 20 are used to support a tubular material, and the tubular material is capable of rotating relative to the support assemblies 20. The line drawing assembly 30 is fixed to the support assembly 20 and includes an adjustment structure 31 and a brush 32. The adjustment structure 31 is driven and connected to the brush 32, and the adjustment structure 31 is used to drive the brush 32 toward the tubular material.

[0047] Using the technical solution of the present application, the pipe is arranged on two support assemblies 20, and the adjustment structure 31 can drive the brush 32 to move in the direction close to the pipe. This arrangement can ensure the clarity of the line drawn by the brush 32, facilitating subsequent cutting. Moreover, during the line drawing process, only one staff member is required to rotate the pipe, reducing the operating cost of the staff member, improving the line drawing efficiency, and thus improving the subsequent cutting efficiency. In addition, because the distance between the two support assemblies 20 is adjustable, the line drawing device can adapt to pipes of different lengths, improving the versatility of the line drawing device.

[0048] Optionally, the paintbrush 32 may be a slate pencil.

[0049] like Figure 2 As shown, the adjustment structure 31 includes a fixing frame 311 , a driving structure 312 and a line drawing structure 313 .

[0050] The fixing bracket 311 is fixed on the supporting assembly 20 .

[0051] The driving structure 312 is fixed on the fixing frame 311, and the drawing structure 313 is arranged on the driving structure 312. The driving structure 312 is used to drive the drawing structure 313 to move toward the direction close to the pipe. The brush 32 is slidably arranged on the drawing structure 313, and the drawing structure 313 can drive the brush 32 to move toward the direction close to the pipe.

[0052] With such arrangement, both the driving structure 312 and the line drawing structure 313 can drive the paintbrush 32 to move, thereby facilitating adjustment of the position of the paintbrush 32 and ensuring the line drawing effect of the paintbrush 32 .

[0053] Specifically, the drive structure 312 includes a lead screw 3121 and a slider 3122. The lead screw 3121 is rotatably mounted on the fixed frame 311 and extends in the direction of extension of the fixed frame 311. The slider 3122 is sleeved on the lead screw 3121, with the bottom of the slider 3122 abutting the fixed frame 311. The lead screw 3121 can drive the slider 3122 to move in the direction of extension of the lead screw 3121. The line drawing structure 313 is fixed to the slider 3122.

[0054] When the lead screw drives the slider 3122 to move on the fixed frame 311, the line drawing structure 313 and the brush 32 move, so that the tip of the brush 32 can abut the surface of the pipe. When the pipe rotates on the support assembly 20, the pipe line drawing is completed. This arrangement makes the line drawing process quick and efficient, while also simplifying the structure, facilitating the rotation of the lead screw 3121, and thus facilitating the movement of the slider 3122. At the same time, because the bottom of the slider 3122 abuts the fixed frame 311, the slider 3122 is prevented from rotating.

[0055] The line drawing structure 313 includes a pen holder 3131 , a connecting block 3132 , a sliding rod 3133 and an elastic member 3134 .

[0056] The pen holder 3131 has a fixing hole and a sliding hole, and one end of the paintbrush 32 is fixed in the fixing hole.

[0057] The connecting block 3132 is fixed on the driving structure 312. The pen holder 3131 and the connecting block 3132 are spaced apart along the extension direction of the fixed frame 311. The connecting block 3132 is used to be set on the side of the pen holder 3131 close to the pipe. A through hole is set on the connecting block 3132, and the other end of the paintbrush 32 can be slidably inserted into the through hole.

[0058] One end of the sliding rod 3133 is fixedly connected to the connecting block 3132 , and the other end of the sliding rod 3133 is slidably disposed in the sliding hole.

[0059] One end of the elastic member 3134 is fixedly connected to the pen holder 3131 , and the other end of the elastic member 3134 is fixedly connected to the connecting block 3132 . The elastic member 3134 can provide an elastic force to drive the pen holder 3131 to move toward the connecting block 3132 .

[0060] With the above structure, the slide rod 3133 passes through the pen holder 3131. Since the brush 32 abuts against the tube, the elastic member 3134 is in a stretched state, which can continuously compensate for the consumption of the tip of the brush 32, so that the tip of the brush 32 can always fit the surface of the tube when drawing, ensuring the clarity of the drawn line.

[0061] Specifically, in the present application, the elastic member 3134 is a spring, and the spring is sleeved on the sliding rod 3133 .

[0062] like Figure 3 As shown, the line drawing structure 313 further includes a fixing member 3135 , which is threadedly connected to the pen holder 3131 and can abut against the paintbrush 32 to fix the paintbrush 32 on the pen holder 3131 , or the fixing member 3135 is screwed into the interior of the paintbrush 32 .

[0063] Specifically, in the present application, the fixing member 3135 is a screw.

[0064] Furthermore, the support assembly 20 includes a support frame 21 and two rollers 22 .

[0065] The support frame 21 is slidably disposed on the base frame 10, and the line drawing assembly 30 is fixed to the support frame 21. Two rollers 22 are rotatably disposed on the support frame 21, and the two rollers 22 are spaced apart along an extension direction perpendicular to the base frame 10, and the pipe is disposed between the two rollers 22.

[0066] Such an arrangement can ensure the stability of the pipe placed on the support assembly 20, prevent the pipe from falling from the support assembly 20, ensure the safety of the staff, and at the same time facilitate the rotation of the pipe, further reducing the operating difficulty of the staff.

[0067] Among them, there is a guide structure between the support frame 21 and the base frame 10 to guide the sliding of the support frame 21. Such an arrangement can ensure the stability of the support frame 21 during movement and prevent the support frame 21 from tilting during movement.

[0068] Specifically, a slide groove 11 is provided on the base frame 10, and the slide groove 11 extends along the extension direction of the base frame 10. A slide 23 is provided at the bottom of the support frame 21, and the slide 23 can be slidably passed through the slide groove 11. The slide groove 11 and the slide 23 cooperate to form a guide structure.

[0069] Such a configuration has a simple structure, is convenient for processing the base frame 10 and the support assembly 20, and is convenient for assembling the base frame 10 and the support assembly 20, and is easy to operate.

[0070] Furthermore, the support assembly 20 includes two support frames 21 , which are respectively arranged at both ends of the roller 22 . A fixing structure 40 is provided between the support assembly 20 and the base frame 10 so as to be fixed to the base frame 10 through the support assembly 20 .

[0071] The above structure facilitates the installation of the roller 22 and ensures the stability of the roller 22 when installed on the support frame 21.

[0072] The bottom of each of the two support frames 21 of the support assembly 20 is provided with a slide 23. The slide 23 has a vertical section 231 and a bent section 232. The vertical section 231 is slidably disposed within the slide groove 11, and the bent section 232 is disposed parallel to the base frame 10. The base frame 10 is provided with a plurality of locking holes 12. This arrangement facilitates the guidance of the support frames 21.

[0073] Optionally, the slide 23 has only one vertical section 231 , and the vertical section 231 is provided at one end of the bending section 232 .

[0074] Alternatively, two slide grooves 11 are provided on the base frame 10 , and the slide frame 23 has two vertical sections 231 . The two vertical sections 231 are respectively located at two ends of the bending section 232 , and the two vertical sections 231 are provided in a one-to-one correspondence with the two slide grooves 11 .

[0075] The staff can select the structure of the slide 23 according to the needs.

[0076] The fixing structure 40 includes a connecting plate 41 and a locking member 42 .

[0077] The ends of the connecting plate 41 respectively abut against the bent sections 232 of the two slides 23. A locking member 42 is provided through the connecting plate 41 and is threadedly connected to the locking hole 12, thereby securing the support assembly 20 to the base frame 10 via the slides 23 and support frame 21. This arrangement provides a simple structure, facilitates securing the support assembly 20, and facilitates changing the position of the fixing structure 40, making it easy to operate.

[0078] Specifically, the line drawing assembly 30 is disposed at the connection between one of the rollers 22 and the support frame 21, and is disposed toward the other roller 22, and extends away from the base frame 10. This arrangement facilitates marking of pipes while preventing interference between the line drawing assembly 30 and other structures, thereby ensuring normal marking operation of the line drawing assembly 30.
