[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 One embodiment provided by this utility model:

[0024] A pipe inner diameter measuring instrument for construction engineering testing includes an inner diameter measuring instrument 1, a placement frame 11 fixedly connected to the surface of the inner diameter measuring instrument 1, a fixed upright 12 fixedly connected to the surface of the inner diameter measuring instrument 1, an extension mechanism provided on the surface of the placement frame 11, the extension mechanism including a guide block 2, the guide block 2 fixedly connected to the surface of the placement frame 11, an extension rod 21 slidably connected to the surface of the guide block 2, a connecting block 22 fixedly connected to the surface of the extension rod 21, an extension frame 23 fixedly connected to the surface of the connecting block 22, a limit bolt 24 threadedly connected to the surface of the guide block 2, and a measuring mechanism provided on the surface of the fixed upright 12. This extension mechanism can support the pipe by cooperating with the placement frame 11 and the extension frame 23, effectively supporting pipes of different lengths, avoiding the problem of long pipes being unable to be placed on the placement frame 11, and improving the adaptability of the pipe inner diameter measuring instrument.

[0025] Furthermore, the measuring mechanism includes a slider 3, which is slidably connected to the surface of the fixed rod 12. A movable block 31 is fixedly connected to the surface of the slider 3, a measuring rod 32 is fixedly connected to the surface of the movable block 31, a spring 33 is fixedly connected to the surface of the movable block 31, a movable rod 34 is fixedly connected to the surface of the spring 33, and a clamping plate 35 is fixedly connected to the surface of the movable rod 34. The movable rod 34 is slidably connected to the surface of the movable rod 34. The two sets of measuring rods 32 on the measuring mechanism will contact the inner wall of the pipe, thereby measuring the inner diameter of the pipe. The measuring rod 32 needs to change position for each measurement of the pipe. The measuring mechanism uses the spring 33 in conjunction with the slider 3, movable block 31, movable rod 34 and clamping plate 35 to form a clamping mechanism, which can quickly change the position of the measuring rod 32 on the fixed rod 12, thereby improving the inner diameter measurement efficiency of the pipe inner diameter measuring device.

[0026] Furthermore, a guide hole is provided on the surface of the guide block 2, and the extension rod 21 slides on the guide hole of the guide block 2. The extension rod 21 drives the extension frame 23 to slide synchronously through the connecting block 22. The extension rod 21 is located on one side of the inner diameter measuring instrument 1 and the placement frame 11, so that the extension rod 21 will not occupy the space of the pipe inner diameter measuring instrument when it is retracted.

[0027] Furthermore, a threaded hole is provided on the guide hole of the guide block 2, and the limiting bolt 24 is threadedly connected to the threaded hole of the guide block 2. The limiting bolt 24 slides through the threaded hole of the guide block 2 to the guide hole of the guide block 2, and the limiting bolt 24 presses against the surface of the extension rod 21 on the guide hole of the guide block 2. The limiting bolt 24 restricts the extension rod 21 from continuing to slide on the guide hole of the guide block 2 through friction, thereby restricting the position of the connecting block 22 and the extension frame 23 through the extension rod 21.

[0028] Furthermore, a triangular groove is provided on the surface of the placement rack 11. The placement rack 11 and the extension rack 23 have the same shape and are always parallel to each other. The extension rack 23 can change the distance between the placement rack 11 and the extension rack 23 by sliding. By changing the distance between the placement rack 11 and the extension rack 23, more different pipes can be placed, thus improving the adaptability of pipe placement.

[0029] Furthermore, a guide groove is provided on the surface of the fixed pole 12, and the slider 3 is slidably connected to the guide groove of the fixed pole 12. The movable block 31 slides and rises and falls on the surface of the fixed pole 12 through the slider 3. The movable block 31 drives the measuring rod 32 to rise and fall synchronously. There are two sets of measuring rods 32. The measuring rods 32 move to the inner wall of the pipe through sliding and rising. The inner diameter measuring instrument 1 detects the inner diameter of the pipe through the two sets of measuring rods 32.

[0030] Furthermore, a guide groove is provided on the surface of the movable block 31, and the movable rod 34 is slidably connected to the guide groove of the movable block 31. The elastic force of the spring 33 passes through the clamping plate 35, and one side of the clamping plate 35 is in contact with the surface of the fixed rod 12. Under the action of the elastic force of the spring 33, the movable rod 34 pulls the clamping plate 35 so that the clamping plate 35 is pressed against the surface of the fixed rod 12. At this time, the slider 3 is also pressed against the guide groove of the fixed rod 12, thus forming a clamping phenomenon, preventing the measuring rod 32 from continuing to slide on the fixed rod 12, so that the measuring rod 32 is temporarily fixed on the surface of the fixed rod 12.

[0031] Working principle: When encountering pipes of different lengths, the extension rod 21 slides on the surface of the placement frame 11 via the guide block 2. The extension rod 21 drives the extension frame 23 to slide on one side of the placement frame 11 via the connecting block 22, thereby changing the distance between the placement frame 11 and the extension frame 23. The distance between the placement frame 11 and the extension frame 23 is adjusted according to the length of the pipe. After the adjustment is completed, the limiting bolt 24 is rotated on the threaded hole of the guide block 2, so that the limiting bolt 24 restricts the position of the extension rod 21 on the guide block 2, thereby restricting the distance between the extension frame 23 and the placement frame 11. The placement frame 11, together with the extension frame 23, can effectively support pipes of different lengths, avoiding the problem of not being able to place the pipe on the placement frame 11 when encountering a longer pipe, thus improving the adaptability of the pipe inner diameter measuring device.

[0032] After the measuring rod 32 has moved, the elastic force of the spring 33 acts on the clamping plate 35 through the movable rod 34, causing the clamping plate 35 to press against one side of the fixed upright 12. The elastic force of the spring 33 acts on the slider 3 through the movable block 31, causing the slider 3 to press against one side of the guide hole of the fixed upright 12. This measuring mechanism, using the spring 33 in conjunction with the slider 3, movable block 31, movable rod 34 and clamping plate 35 to form a clamping mechanism, can quickly change the position of the measuring rod 32 on the fixed upright 12, thereby improving the inner diameter measurement efficiency of the pipe inner diameter measuring instrument.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
