Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to a device for detecting inner and outer diameters of building pipe fittings. Background Art

[0002] In construction projects, pipe fittings are generally used to transport some liquids or gases. Due to the mutual movement between the medium in the pipe fittings and the inner wall of the pipe fittings, the inner wall of the pipe will be worn over time. The outer surface of the pipe fittings will also be worn due to sun, rain or other factors. When the inner or outer surface of the pipe fittings is worn to a certain extent, the pipe fittings will easily break and cannot meet the requirements of use. Therefore, it is usually necessary to regularly test the outer and inner diameters of the pipe fittings. In addition, during the construction inspection, the inner and outer diameters of the pipe fittings also need to be tested to ensure that they meet the construction quality requirements.

[0003] The Chinese utility model patent with announcement number CN217275939U discloses a tool for measuring inner and outer diameters of pipelines, including a rod body, a fixed scale, outer diameter scale lines, inner diameter scale lines, a level, a dial block, an inner diameter pointer, an outer diameter pointer, a moving scale, a dial block slide groove, a slider slide groove and a slider. The moving scale can slide on the rod body. After the fixed scale contacts the inner wall or outer wall of the pipeline, the moving scale can be made to contact the inner wall or outer wall of the pipeline by sliding the moving scale. At this time, the inner diameter or outer diameter of the pipeline can be obtained by observing the scale number on the inner diameter scale line indicated by the outer diameter pointer or the scale number on the outer diameter scale line indicated by the inner diameter pointer.

[0004] The device is provided with a rod body, a fixed ruler is horizontally fixedly connected to the bottom of one side of the rod body, a slider slot is opened on the rod body, a slider is slidably installed in the slider slot, and a moving ruler is horizontally fixedly connected to one side of the slider. When measuring the inner and outer diameters of the pipe fitting, the fixed ruler contacts the inner wall or outer wall of the pipe and then slides the moving ruler to measure the inner diameter or outer diameter of the pipe fitting. However, the device can only measure the inner diameter or outer diameter separately at a time, and the position of the moving ruler needs to be cut multiple times during the detection process, which is cumbersome to operate and has low measurement efficiency.

The motor 2 is fixedly arranged on the housing 1, and the output shaft of the motor 2 is connected and fixed to one end of the screw 3. The screw 3 is located in a slide groove 101 and is rotatably connected to the housing 1. Threaded sections in opposite directions are provided on both sides of the screw 3. Two groups of outer clamps 5 are respectively threadedly sleeved on one side of the screw 3. The connecting rod 4 is located in a slide groove 101 and is rotatably connected to the housing 1. The inner top plate 6 is provided with a through hole 1 601 matched with the screw 3 and a through hole 2 602 matched with the connecting rod 4. The spring 7 is provided in two groups and is respectively sleeved on one side of the connecting rod 4. Both ends of the spring 7 are respectively connected and fixed to the inner top plate 6 and the housing 1. The outer clamp 5 is provided with a through hole 3 501 matched with the spring 7. The clamping strips 401 are fixedly arranged on both sides of the connecting rod 4, and the inner wall of the through hole 2 602 is provided with a clamping groove 603 matched with the clamping strip 401.

[0028] In at least one embodiment, the clamping strips 401 are provided in multiple groups and are arranged at intervals along the circumference of the connecting rod 4 . By providing multiple groups of clamping strips 401 , the inner top plate 6 is limited at multiple points to ensure the stability of the inner top plate 6 .

[0029] In at least one embodiment, arc grooves are provided on adjacent sides of the two groups of outer clamping plates 5 outside the shell 1, and arc protrusions are provided on separated sides of the two groups of inner top plates 6 outside the shell 1. By providing the arc grooves and arc protrusions, it is convenient to abut the arc wall of the pipe fitting to ensure the detection accuracy.

[0030] In at least one embodiment, a rubber pad is fixedly provided on one side of the shell 1 close to the protruding end of the outer clamping plate 5. The rubber pad is provided to avoid damage to the shell 1 when it abuts against the pipe fitting, thereby ensuring safety.

[0031] In at least one embodiment, a second slide groove 102 is provided on the inner wall of the first slide groove 101 along the axial direction of the screw rod 3, and a clamping block 103 matched with the second slide groove 102 is fixedly provided on the outer splint 5 and the inner top plate 6.

[0033] In at least one embodiment, handles 8 are fixedly provided on both sides of the housing 1 to facilitate the staff to move the device.

[0034] When inspecting the inner and outer diameters of the pipe fitting, the staff starts the motor 2 on the shell 1, and the motor 2 drives the screw 3 to rotate. The screw 3 drives the two groups of outer clamping plates 5 to move away from each other along the axial direction of the screw 3 through the threaded sections in opposite directions on both sides. When the distance between the two groups of outer clamping plates 5 is larger than the outer diameter of the pipe fitting, the side of the shell 1 close to the protruding end of the outer clamping plate 5 is abutted against the open end of the pipe fitting, and then the motor 2 is started to reverse and drive the two groups of outer clamping plates 5 to move closer to each other, and clamp the outer wall of the pipe fitting. At this time, the two groups of inner top plates 6 are located in the middle of the slide groove 101 and the spring 7 is in a stretched state. Then the staff rotates the connecting rod 4 to make the connecting rod 4 drive the clamping strip 401 to rotate. When the clamping strip 401 rotates to align with the clamping groove 603 on the inner top plate 6, the inner Under the pulling force of the spring 7, the top plate 6 moves axially along the connecting rod 4 and approaches the inner wall of the pipe fitting, and finally abuts against the inner wall of the pipe fitting under the action of the spring 7. At this time, the distance between the two groups of inner top plates 6 and the two groups of outer clamping plates 5 can be read through the scale lines on the shell 1, so that the inner diameter and outer diameter of the pipe fitting can be measured simultaneously, which improves the detection efficiency. When it is necessary to switch the detection position, the pipe fitting is taken out and then the two groups of outer clamping plates 5 can drive the two groups of inner top plates 6 to move toward the middle of the slide groove 101 by reversing the motor 2. When the clamping strip 401 is disengaged from the clamping groove 603, the connecting rod 4 is rotated to make the clamping strip 401 and the clamping groove 603 misaligned, so as to limit the inner top plate 6 and restore it to its original state, which is convenient for measuring other positions of the pipe fitting and easy to operate.
