[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a thickness detection device for plastic pipe production includes a handle 1, a handle hole 2 is formed on the handle 1, a dial mechanism is installed on the top of the handle 1, and the dial mechanism is used to display the pipe thickness. A measuring mechanism is arranged on the right-angle inner side of the handle 1, and the measuring mechanism is used to measure the wall thickness of the pipe. An adjusting mechanism is arranged on the measuring mechanism, and the adjusting mechanism is used to adjust and correct the measuring mechanism when the measuring mechanism is worn; a fixed seat 3 is fixedly installed on the top arc surface of the handle 1, a rotating arm 4 is rotatably installed on the outer wall of the fixed seat 3, a notch 5 is formed inside the rotating arm 4, and two movable columns 6 are symmetrically and fixedly connected to the outer periphery above the lifting column 7, and the two movable columns 6 are slidably connected to the inner wall of the notch 5.
[0021] In this embodiment: First, when measuring the pipe to be measured, a downward pressing force is applied to one end of the rotating arm 4 by the thumb. At this time, the rotating arm 4 rotates around the center of the fixed seat 3. At this time, the other end of the rotating arm 4 drives the notch 5 to rotate upward synchronously. The inner wall of the notch 5 squeezes the outer periphery of the movable column 6, and the movable column 6 pulls the upper half of the measuring mechanism upward to move, so that a sufficient distance is generated between the upper half and the lower half of the measuring mechanism. Then, the detection is closed, and then the pressure applied to the rotating arm 4 is removed. At this time, the upper half of the measuring mechanism resets downward, and the upper half and the lower half of the measuring mechanism clamp the inner and outer peripheries of the pipe wall. After clamping, the pipe wall thickness is displayed on the dial mechanism, and then it can be read to achieve the purpose of measuring the pipe wall thickness.
[0022] Please pay special attention to Figure 1 , Figure 2, the dial mechanism includes a support rod 8 fixedly connected to the top plane of the handle 1. One support rod 8 is of a hollow structure. The top of the support rod 8 is fixedly connected to a watch case 9. The inner side of the back plate of the watch case 9 is rotatably connected to a rotating shaft. A gear 17 is press-fitted on the outer wall of the rotating shaft. One end of the gear 17 is snap-connected to a torsion spring 18 between the inner side of the back plate of the watch case 9. The end of the rotating shaft away from the back plate is fixedly connected to a pointer 11. The inner circumference of the watch case 9 is fixedly connected to a dial 10. The rotating shaft is rotatably connected to the dial 10.
[0023] In this embodiment: When the measuring mechanism measures, the up-and-down movement of the upper half of the measuring mechanism drives the gear 17 to rotate. The gear 17 drives the rotating shaft to rotate. At this time, the end of the torsion spring 18 engaged with the gear 17 rotates with the gear 17. At this time, the torsion spring 18 is twisted. The rotating rotating shaft drives the pointer 11 to rotate. The value pointed to by the pointer 11 is the value of the pipe thickness.
[0024] Please refer specifically to Figure 1 、 Figure 3 and Figure 4 , the measuring mechanism includes a rotating column 12 and a lifting column 7 that penetrates through the hollow support rod 8, the watch case 9 from below the support rod 8 and extends above the watch case 9. A connecting column 15 is fixedly connected to the outer circumference of the rotating column 12. An annular tooth 16 is fixedly connected to the outer wall of the inner cavity of the watch case 9 where the lifting column 7 is located. The bottom end of the lifting column 7 is detachably connected to a spherical column 14. The lowest point on the outer circumference of the spherical column 14 in the reset state is in contact with the highest point on the outer circumference of the connecting column 15.
[0025] In this embodiment: When the lifting column 7 moves, the annular tooth 16 on its outer part meshes with the gear 17. The upward-moving lifting column 7 drives the annular tooth 16 to drive the gear 17 to rotate for measurement.
[0026] Please refer specifically to Figure 1 、 Figure 3 and Figure 4 , the adjusting mechanism includes a chute 22 opened on the right-angled vertical side of the handle 1. The top end of the inner wall of the chute 22 is rotatably connected to a stud 21 that penetrates to the lower part of the handle 1. The stud 21 is rotatably connected to the handle 1, and the bottom end of the stud 21 is fixedly connected to a knob 13. A slider 19 that is threadedly connected to the outer wall of the stud 21 and slides in the chute 22 is fixedly connected to the rotating column 12. The adjusting mechanism also includes a threaded hole opened at the bottom end of the lifting column 7 and recessed upward. A screw 20 is threadedly connected to the inner wall of the threaded hole. The bottom end of the screw 20 is integrally formed with the top of the spherical column 14.
[0027] In this embodiment: When measuring the wall thickness of the pipe, due to the long-term contact between the bottom of the ball column 14 and the outer circumference of the pipe, wear will occur. The wear will cause the overall height of the ball column 14 to decrease. Then, when the torsion spring 18 resets, the lifting column 7 and the ball column 14 will reset and move downward by an increased distance, resulting in excessive reset of the gear 17. At this time, the pointer 11 will rotate towards the maximum value direction and cannot return to zero, resulting in measurement deviation.
[0028] Therefore, when this situation occurs, by rotating the knob 13, the knob 13 drives the stud 21 to rotate. At this time, the slider 19 moves upward under the action of its internal thread. The upward-moving slider 19 drives the connecting column 15 to move upward. The upward-moving connecting column 15 pushes the ball column 14 upward until the pointer 11 returns to zero, thus avoiding measurement errors. Since the thread of the stud 21 has self-locking properties, it can prevent the connecting column 15 from moving during the measurement process.
[0029] When the ball column 14 is worn out excessively, the ball column 14 can be rotated. The ball column 14 drives the screw rod 20 to separate from the threaded hole, thereby replacing the ball column 14.
[0030] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
