The technical purpose of the invention is realized by the following technical scheme: a plastic pipe scribing device comprises two flexible belts which are not in contact with each other, are parallel to each other and are aligned at two ends, wherein sliding grooves are formed in the same side of the two flexible belts, the sliding grooves extend along the length direction of the flexible belts, a U-shaped sliding block is arranged on the two flexible belts in a sliding mode through the two sliding grooves formed in the two flexible belts, a movable rod penetrates through the sliding block in a movable mode, the movable rod penetrates through the two flexible belts, a scribing part is embedded into the penetrating end of the movable rod, traces can be left on a plastic pipe after the scribing part is in contact with the plastic pipe, a pressing part is arranged at one end, far away from the scribing part, of the movable rod, and the pressing part and the movable rod form a T-shaped structure.

Furthermore, a plurality of suckers are arranged on one side, away from the sliding groove, of each of the two flexible belts.

Furthermore, a spring is sleeved at the position of the movable rod between the pressing part and the sliding block.

Furthermore, a flange which protrudes outwards along the radial direction of the movable rod is integrally and fixedly arranged at the position of the movable rod between the scribing part and the sliding block.

Furthermore, a convex tooth structure which is meshed with each other is arranged between the sliding contact surfaces of the sliding groove and the sliding block.

In conclusion, the invention has the following beneficial effects:

according to the plastic pipe scribing device, the two flexible belts are attached to the outer wall of the plastic pipe, the pressing part is pressed, the scribing part is in contact with the outer wall of the plastic pipe, the sliding block slides along the sliding groove, the scribing part is scribed on the outer wall of the plastic pipe, the sliding direction of the sliding block is limited by the sliding groove, the moving route of the scribing part is stable, and accordingly the scribing part can be scribed on the outer wall of the plastic pipe stably and clearly.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a plastic tubing scribing apparatus includes two non-contact, parallel flexible belts 1 with two aligned ends, a sliding groove 2 is formed on the same side of each of the two flexible belts 1, the sliding groove 2 extends along the length direction of the flexible belt 1, a U-shaped sliding block 4 is slidably disposed on each of the two flexible belts 1 through the two sliding grooves 2 formed on the two flexible belts, a movable rod 5 movably penetrates through the sliding block 4, the movable rod 5 penetrates between the two flexible belts 1, a scribing portion 8 is embedded in the penetrating end of the movable rod 5, a trace can be left on the plastic tubing after the scribing portion 8 contacts the plastic tubing, a pressing portion 6 is disposed at one end of the movable rod 5 far from the scribing portion 8, and the pressing portion 6 and the movable rod 5 form a T-shaped structure.

By the technical scheme, when marking, firstly two flexible belts 1 are attached to the outer wall of the plastic pipe, then the pressing part 6 is pressed to extend the movable rod 5 towards the direction of the pipe material until the scribing part 8 at the other end of the movable rod 5 is contacted with the pipe material, then, while keeping the pressing part 6 pressed and sliding the slider 4 along the slide groove 2, the scribing part 8 moves along with the slider 4, and the scribing part 8 performs scribing around the pipe, since the sliding of the slider 4 is restricted by the slide groove 2, the sliding path is fixed, so that the scribing path of the scribing part 8 is also fixed and stable, the scribing part 8 can scribe on the outer wall of the plastic pipe stably and clearly without deflection and interruption, after the scribing is finished, the two flexible belts 1 are slightly straightened and then taken down from the pipe, and the whole process is very convenient.

Furthermore, a plurality of suckers 3 are arranged on one sides of the two flexible belts 1 far away from the sliding groove 2, and when the flexible belts 1 are attached to the outer wall of the plastic pipe, the suckers 3 can be firmly attached to the outer wall of the pipe, so that the two flexible belts 1 can be positioned, and the two flexible belts 1 can be firmly attached to the pipe even if not held by hands during scribing.

Further, the movable rod 5 is located and has cup jointed spring 7 in the position department of pressing between portion 6 and the slider 4 of pressing, presses portion 6 pressurized after, and spring 7 is compressed and produces reverse elastic action, loosens and presses portion 6 after, under the effect of spring 7's reverse elastic action, presses portion 6 and can get back to original position rapidly, and then has realized the automatic re-setting of movable rod 5.

Further, a flange 9 protruding outward in the radial direction of the movable rod 5 is integrally and fixedly arranged at a position of the movable rod 5 between the scribing portion 8 and the slider 4, and the flange 9 can prevent the movable rod 5 from being separated from the slider 4 and falling out.

Furthermore, a mutually meshed convex tooth structure is arranged between the sliding contact surfaces of the sliding chute 2 and the sliding block 4, and the convex tooth between the sliding chute 2 and the sliding block 4 does not influence the sliding motion between the sliding chute and the sliding block, but can ensure that the sliding block 4 cannot be separated from the sliding chute 2.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
