Description

Technical Field

[0001] The utility model relates to the technical field of pipe detection, in particular to a device for detecting the inner diameter of a construction pipe. Background Art

[0002] During construction, it is necessary to lay water supply pipes, drainage pipes, rainwater pipes and other pipes. It is inevitable to use construction pipes of various materials. Whether the pipes entering the site are qualified directly affects the quality of the laid pipes. Therefore, it is necessary to conduct on-site inspection of the construction pipes before they enter the site, and the on-site inspection of the construction pipes includes the inner diameter inspection.

[0003] At present, the inner diameter of construction pipes is detected by manually using a vernier caliper to directly measure the inner diameter of the pipe to be tested. During the detection process, when the inner diameter of the pipe is measured by a vernier caliper, the measurement technique and human factors have a relatively large impact, and it cannot be guaranteed that the line connecting the two verniers passes through the center of the plastic pipe. Therefore, the distance between the two verniers may be smaller than the inner diameter of the pipe, resulting in low measurement accuracy. In addition, due to the different uses of pipes, their sizes and specifications are also diverse. The existing vernier caliper is difficult to meet the use requirements. Therefore, a construction pipe inner diameter detection device is proposed. Summary of the invention

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a device for detecting the inner diameter of a construction pipe, comprising a housing 1, a rotating disk 2 and a fixed disk 3, a rotating groove 11 is provided in the housing 1, the rotating disk 2 is installed in the rotating groove 11, a mounting groove 12 is provided on one side of the housing 1, the fixed disk 3 is installed in the mounting groove 12, a through hole 1 22 and a through hole 2 32 are respectively provided in the middle of the rotating disk 2 and the fixed disk 3, and a rotating rod 5 is passed through the through hole 1 22 and the through hole 2 32;

[0029] The rotating disk 2 is evenly provided with arc-shaped through holes 21, and the fixed disk 3 is evenly provided with straight holes 31. The arc-shaped through holes 21 are matched with the straight holes 31, and a connecting rod 4 runs through the arc-shaped through holes 21 and the straight holes 31.

[0030] The housing 1 forms an inner diameter detection mechanism through a rotating disk 2, a fixed disk 3, a connecting rod 4 and a rotating rod 5.

[0031] In this embodiment, specifically: the inner diameter detection mechanism composed of various structures can effectively measure the inner diameter of the pipeline, and the rotating disk 2 and the fixed disk 3 are supported by the shell 1. At the same time, the installed rotating disk 2 is rotated by the rotating rod 5 under the action of external force, thereby driving the connecting rod 4 connected to the rotating disk 2 and the fixed disk 3 to move horizontally, thereby effectively completing the detection of the inner diameter of the pipeline.

[0032] In the present embodiment, specifically: limiting holes 13 are evenly provided in the shell 1 and on the side adjacent to the rotating groove 11 and the mounting groove 12, receiving grooves 14 are evenly provided on the shell 1, and the limiting holes 13 are communicated with the receiving grooves 14. The limiting holes 13 can ensure the stable operation of the connecting plate 41 on the one hand, and can cooperate with the arc-shaped through hole 21 on the rotating disk 2 and the straight hole 31 on the fixed disk 3 on the other hand to effectively limit the running distance of the connecting plate 41, and the receiving groove 14 is used to receive the clamping head on the connecting plate 41 so that it can be completely embedded in the receiving groove 14, thereby not changing the outer diameter of the shell 1.

[0033] In this embodiment, specifically: a connecting plate 41 is welded on the connecting rod 4, and the connecting plate 41 passes through the limiting hole 13;

[0034] Among them, a ruler and a clamping plate 42 are respectively integrally formed at both ends of the connecting rod 4. The connecting rod 4 is made to move horizontally through the operation of the rotating disk 2, and then connected to the connecting plate 41 thereon for linkage. The ruler and scale lines set on the connecting rod 4 cooperate with each other, so that the inner diameter value of the pipeline can be obtained more conveniently. At the same time, the clamping plate 42 set on the connecting rod 4 can effectively prevent the connecting rod 4 from being separated from the running rotating disk 2.

[0035] In this embodiment, specifically: a "cross" shaped groove 23 is opened on the rotating disk 2 and located on the side of the second through hole 32 away from the fixed disk 3. The opened "cross" shaped groove 23 is used to receive the "cross" shaped block 51 on the rotating rod 5, and then the rotating disk 2 is driven to rotate by external force.

[0039] Working principle: When in use, the "cross"-shaped card block 51 is inserted into the "cross"-shaped groove 23, and the rotating rod 5 is rotated by external force to drive the rotating disk 2 to perform circular motion. At this time, the connecting rod 4 is driven by the arc-shaped through hole 21 opened on the rotating disk 2, and the running direction of the connecting rod 4 is limited by the straight hole 31 opened on the fixed disk 3, thereby realizing the horizontal operation of the connecting rod 4. At the same time, under the action of external force, multiple connecting rods 4 are synchronously linked to ensure the accuracy of the measurement of the inner diameter of the pipeline. When the connecting plate 41 is adjusted to contact the inner diameter of the pipeline, the value of the scale line where the ruler is located is read, and the two values ​​are added to the size of the shell 1 to accurately obtain the size of the inner diameter of the pipeline;

[0040] It should be further emphasized that when encountering a larger or smaller pipe, the "cross"-shaped clamping block 51 is disengaged from the "cross"-shaped groove 23 by pushing forward, and the corresponding inner diameter detection mechanism is independently selected according to the actual detection situation, and the "cross"-shaped clamping block 51 is inserted into the "cross"-shaped docking groove 52 of the rotating rod 5 of the selected inner diameter detection mechanism, and the inner diameter of the pipe is detected in the same manner as the above operation.
