Detailed Implementation

[0037] Please refer to the attached document. Figure 1 - Figure 6This application illustrates an adjustable multi-tube steel pipe auxiliary marking and positioning device provided in an embodiment of the present application, used to assist in marking steel pipes. Specifically, it includes: a frame 1 and a side wheel assembly 6. A pen clamping assembly 2 is provided at the top center of the frame 1. The pen clamping assembly 2 is used to fix and clamp the marking pen 7. When the frame 1 moves, it drives the marking pen 7 to draw lines on the side of the pipe 3. Two sets of side wheel assemblies 6 are provided, and the two sets of side wheel assemblies 6 are installed on the two sides of the frame 1 respectively. The two sets of side wheel assemblies 6 slide on the two sides of the pipe 3. The distance between the two sets of side wheel assemblies 6 is adjustable to adapt to use on pipes 3 of different diameters.

[0038] like Figure 1 As shown, the frame 1 is mounted above the pipe 3, and two sets of side wheel assemblies 6 are on both sides of the pipe 3. The tip of the marking pen 7 is located on the pipe 3. The user manipulates the frame 1 to move along the axis of the pipe 3. Under the constraint of the two sets of side wheel assemblies 6, the movement of the frame 1 and the marking pen 7 is more stable, ensuring the standard and continuity of the marking.

[0039] In one embodiment, to facilitate the user's manipulation of the frame 1, a pull rod 4 is fixedly connected to the front side of the frame 1. This allows the user to grasp the pull rod 4 to manipulate the frame 1, making it more convenient to use.

[0040] In one embodiment, in order to keep the tie rod frame 4 in a horizontal state, a height positioning member 5 is installed at the center of the tie rod frame 4, and the bottom of the height positioning member 5 abuts against the side of the tube 3, thus preventing the frame 1 from flipping over.

[0041] Specifically, the height positioning component 5 includes: a column 501 and a stop block 502.

[0042] A mounting hole is provided at the center of the tie rod bracket 4. The column 501 is located inside the mounting hole and is fixed with screws. In actual use, the screws are loosened, the height of the column 501 is adjusted up and down, and then the screws are tightened to fix the column 501. The abutment block 502 is fixedly connected to the bottom end of the column 501, and the bottom end of the abutment block 502 is provided with an arc-shaped opening. The arc-shaped opening can be locked on the upper side of the pipe 3, so that the height positioning part 5 is located in the middle of the pipe 3, further ensuring that the marking pen 7 is in the middle of the pipe 3.

[0043] In one embodiment, the pen clamping assembly 2 includes: a circular hole 201 at the center of the top of the frame 1, a clamping metal sheet 202, an annular member 203, an elastic member 204, and a ring post 206.

[0044] Several ring-shaped clamping metal pieces 202 are fixedly connected to the inner side of the circular hole 201. The clamping metal pieces 202 are in an inclined state. The ring-shaped clamping metal pieces 202 constitute the central area for clamping the marking pen 7. The ring 203 is fixedly connected to the bottom of the frame 1 through the elastic member 204. The ring 203 can press the elastic member 204 upward, so that the ring 203 can move elastically. The top of the ring 203 is fixedly connected to the ring post 206 located below the elastic member 204.

[0045] The user pushes the ring 203 upward, causing the ring 203 to compress and deform the elastic element 204. The ring 203 moves upward, which in turn causes the ring column 206 fixed to the ring 203 to compress and hold the metal sheet 202 upward. The holding metal sheet 202 deforms, and the central area formed by several ring-shaped holding metal sheets 202 becomes larger. The marking pen 7 is inserted into the central area, and the ring 203 is released. Under the action of the elastic element 204, the ring 203 and the elastic element 204 move downward, and the holding metal sheet 202 clamps and fixes the marking pen 7 in a U-shape.

[0046] To facilitate pushing the annular part 203 upward, a side ear bracket 205 is fixedly connected to the side of the annular part 203. In actual use, the annular part 203 can be pushed upward by pressing the side ear bracket 205 with two fingers.

[0047] In one embodiment, the side wheel assembly 6 includes: a threaded post 601, a nut 602, a wheel frame 604, and a spring 603.

[0048] The threaded post 601 is slidably connected to the side of the frame 1, and the part of the threaded post 601 located on the outside of the frame 1 is threaded with a nut 602. The nut 602 is used to restrict the threaded post 601 from moving inward. The back of the wheel frame 604 is fixedly connected to the end of the threaded post 601 located on the inside of the frame 1, and a side wheel 605 is rotatably mounted on the wheel frame 604. A spring 603 is sleeved on the threaded post 601 and located between the back of the wheel frame 604 and the inside of the frame 1. The spring 603 causes the threaded post 601, the wheel frame 604, and the side wheel 605 to move inward, so that the side wheel 605 abuts against the outside of the pipe 3.

[0049] In one embodiment, the side wheel assembly 6 includes: a threaded post 601, a wheel frame 604, a side wheel body 605, and two second nuts.

[0050] The threaded post 601 is slidably connected to the side of the frame 1, and the threaded post 601 is threaded with a second nut on both the inner and outer sides of the frame 1. The threaded post 601 is fixed to the frame 1 by the two second nuts. Moreover, the relative position of the threaded post 601 and the frame 1 can be adjusted by adjusting the two second nuts. The back of the wheel frame 604 is fixedly connected to the end of the threaded post 601 located on the inner side of the frame 1, and a side wheel 605 is rotatably mounted on the wheel frame 604.
