Technical Field
[0001] The utility model relates to the technical field of pipe detection, in particular to a pipe equal division marking tool. Background Technique
[0002] In the daily work of the building materials test department, different building materials need to be detected. Generally, in pipe detection, it is necessary to equally divide according to the pipe diameter. For example, when the pipe diameter is small, the surface of the pipe needs to be evenly divided into 3 equal parts for marking during detection. Therefore, with the change of the pipe diameter, it is necessary to mark for 4 equal divisions, 6 equal divisions and 8 equal divisions.
[0003] At present, in pipe detection, there is a lack of professional tools for assisting pipe marking. When personnel mark on the pipe, they first make equal division marks along the pipe wall or the pipe ring, and then mark, which is rather cumbersome. Moreover, the angle ruler is prone to poor equal division accuracy during equal division, which is very inconvenient and affects the detection efficiency and accuracy. Content of the Utility Model

Limit sliding blocks are arranged at both the left and right ends inside the mounting seats, which is convenient for adjusting the position of the paintbrush seat.
[0008] Preferably, limiting sliding grooves are formed on both the left and right sides of the surface of the sliding rod. The limiting sliding grooves are slidably connected with limiting sliding blocks. A ball is rotatably connected to the lower end of the sliding rod. When the ball contacts the pipe, the friction is reduced, facilitating the movement of the auxiliary annular frame.
[0009] Preferably, the connection assembly includes a connection screw rod. The connection screw rod is in threaded connection with the mounting seat. A threaded hole is formed on the inner surface of the limiting sliding groove. One end of the connection screw rod extends to the outside of the mounting seat and is fixedly connected with a rotating handle.

A plurality of threaded holes are provided. Six and eight threaded holes are respectively provided in the two groups of displacement frames in an annular array. Thus, in the equal division of the pipe, according to the pipe size, scribing of three equal divisions, four equal divisions, six equal divisions, and eight equal divisions can be achieved.
[0011] Preferably, a pen hole is formed in the pen seat. The pen hole penetrates the pen seat from top to bottom. The limiting bolt is in threaded connection with the pen seat. One end of the limiting bolt extends to the inside of the pen hole, and the end face is designed with an arc structure, installing the paintbrush in the pen hole and using the limiting bolt to limit and lock the paintbrush. Beneficial effects
[0012] The utility model provides a tool for scribing equal divisions of pipes. Compared with the prior art, the following beneficial effects are achieved:

The displacement frame 3 is composed of a slide bar 31, a lower connecting plate 32, an upper connecting plate 33 and a guide rod 34. Two slide bars 31 are symmetrically arranged on both the front and rear sides of the auxiliary annular frame 1. The lower ends of the two slide bars 31 are fixedly connected through the lower connecting plate 32, and the upper ends of the two slide bars 31 are fixedly connected through the upper connecting plate 33. A guide rod 34 is arranged between the two upper connecting plates 33. The upper and lower ends of the guide rod 34 are respectively fixedly connected with the lower connecting plate 32 and the upper connecting plate 33. Limit chutes 311 are opened on both the left and right sides of the surface of the slide bar 31, and the limit chutes 311 are slidably connected with the limit sliders 22. A ball 312 is rotatably connected to the lower end of the slide bar 31. Two groups of displacement frames 3 are respectively arranged in a circular array of six and eight. Thus, in the equal division of pipes, according to the pipe size, marking of three equal divisions, four equal divisions, six equal divisions and eight equal divisions can be realized. Furthermore, according to the equal division requirements, the displacement frame 3 at the corresponding angle is adjusted so that the ball 312 fits with the surface of the pipe, which is convenient for the movement of the auxiliary annular frame 1;
[0021] A connecting component 4 is arranged between the displacement frame 3 and the mounting seat 2. The connecting component 4 includes a connecting screw 41 which is in threaded connection with the mounting seat 2. A threaded hole 42 is formed in the inner surface of the limiting sliding groove 311. One end of the connecting screw 41 extends to the outside of the mounting seat 2 and is fixedly connected with a rotating handle 43. The other end of the connecting screw 41 extends to the inside of the mounting seat 2 and is in threaded connection with the threaded hole 42. There are two sets of displacement frames 3, and the two displacement frames 3 are both distributed in an annular array. The guide rod 34 is slidably connected with the auxiliary annular frame 1. There are multiple threaded holes 42. When the displacement frame 3 is adjusted, the sliding rod 31 slides in the mounting seat 2, and then the rotating handle 43 is rotated to drive the connecting screw 41 to rotate and enter the threaded hole 42, so as to fix the position of the displacement frame 3, and the multiple threaded holes 42 can adapt to pipes of different sizes;

There are six and eight displacement frames 3 respectively arranged in an annular array in the two groups. Therefore, in the equal division of the pipe, according to the pipe size, scribing for trisecting, quadrisection, sexsection and octasection can be realized. Furthermore, according to the equal division requirement, the displacement frame 3 at the corresponding angle is adjusted so that the ball 312 fits the surface of the pipe. When the displacement frame 3 is adjusted, the sliding rod 31 slides in the mounting seat 2, and then the rotating handle 43 is rotated to drive the connecting screw 41 to rotate and enter the threaded hole 42, so as to fix the position of the displacement frame 3, and the multiple threaded holes 42 can adapt to pipes of different sizes. Then the auxiliary annular frame 1 is moved, and the paintbrush slides on the surface of the pipe, so that the scribing step in the detection of pipe fittings can be completed quickly and accurately, improving the practicability.
