It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] like Figure 1 As shown, a plastic product length measuring device includes a ruler 1 and a slide 2. The slide 2 is arranged in the middle of the ruler 1. Slide bars 21 are symmetrically arranged inside the slide 2. An indicating component 3 sliding along the slide bar 21 is arranged inside the slide 2. There are several indicating components 3. A positioning component 4 for positioning the indicating component 3 is arranged in the middle of the indicating component 3.

[0023] According to the above structure, when measuring plastic pipes, align the ruler 1 with the pipe for measurement. After measuring a calibration position, slide the indicating component 3 to the corresponding position, and then position the indicating component 3 through the positioning component 4, so as to calibrate the measuring length of the calibration position, and then measure the next calibration position according to the above method. This measuring instrument can measure multiple calibration targets and has strong practicality.

[0024] like Figure 2 As shown, scale lines 11 are provided on both sides of the bottom end of the ruler 1.

[0025] According to the above structure, both sides of the ruler 1 can be measured, which is convenient for measurement.

[0026] like Figure 3 and 4 As shown, the indicating component 3 includes a T-shaped slider 31, and two slide bars 21 are slidably connected to the two sides of the T-shaped slider 31 respectively. The top of the T-shaped slider 31 is fixedly connected to a top plate 32, a circular hole 33 is provided in the middle of the top plate 32, and a circular ring 34 is fixedly connected to the top of the top plate 32. The side walls of the circular ring 34 are symmetrically provided with arc-shaped pointers 35.

[0027] According to the above structure, when calibrating the measurement scale, the T-shaped slider 31 is slid, and the top plate 32 and the ring 34 on the top plate 32 slide with the T-shaped slider 31, and the arc-shaped pointer 35 on the side wall of the ring 34 stops sliding when it slides to the calibration scale.

[0028] like Figure 4 and 5 As shown, the positioning assembly 4 includes two symmetrically arranged extrusion blocks 41, both sides of the T-shaped slider 31 are provided with a placement groove 42, the two extrusion blocks 41 are slidably connected to the inside of the two placement grooves 42, a central groove 43 is provided in the middle of the top of the T-shaped slider 31, one end of the placement groove 42 is connected to the side wall of the central groove 43, a cylinder 44 is slidably connected inside the central groove 43, the top of the cylinder 44 passes through the circular hole 33 and the circular ring 34 in sequence, the top of the cylinder 44 is fixedly connected to a pulling handle 47, and the cylinder 4 4 is symmetrically provided with an extrusion piece 48 for extruding the extrusion block 41, and the extrusion piece 48 includes an arc plate 481 fixedly connected to the bottom of the side wall of the cylinder 44, and the side wall of the arc plate 481 is fixedly connected with V-shaped elastic sheets 482 equidistantly distributed around the axis of the cylinder 44, and a groove is provided on one side of the extrusion block 41, and an arc-shaped groove 45 is provided in the middle of the groove, and a spring 46 is fixedly connected inside the cylinder 44, and the two ends of the spring 46 are fixedly connected to the top of the inner wall of the cylinder 44 and the bottom end of the center groove 43, respectively.

[0029] According to the above structure, after the sliding T-shaped slider 31 stops, the pulling handle 47 is pressed downward, the cylinder 44 is pressed downward and the extrusion spring 46 is fixed. After the cylinder 44 moves downward, the V-shaped elastic sheet 482 is compressed while moving downward. When the V-shaped elastic sheet 482 is compressed, the extrusion block 41 is pressed against one side of the slide bar 21, so that the T-shaped slider 31 can be positioned at the corresponding position. As the cylinder 44 moves downward, the inflection point of the V-shaped elastic sheet 482 moves to the inside of the arc-shaped groove 45 to prevent the cylinder 44 from being bounced upward. After the scale is recorded, the pulling handle 47 is pulled upward, thereby pulling the cylinder 44 upward, and the inflection point of the V-shaped elastic sheet 482 is pulled out of the arc-shaped groove 45. When the V-shaped elastic sheet 482 is pulled out of the groove on one side of the extrusion block 41, the extrusion block 41 and the slide bar 21 are loosened, and the T-shaped slider 31 can be slid to reset.

[0030] The working principle of the utility model is as follows: when measuring plastic pipes, align the ruler 1 with the pipe for measurement. After measuring a calibration position, slide the indicating assembly 3 to the corresponding position, and then position the indicating assembly 3 through the positioning assembly 4, so as to calibrate the measuring length of the calibration position, and then measure the next calibration position according to the above method. The measuring device can measure multiple calibration targets and has strong practicality. When calibrating the measurement scale, slide the T-shaped slider 31, the top plate 32 and the ring 34 on the top plate 32 slide with the T-shaped slider 31, and stop sliding when the arc pointer 35 on the side wall of the ring 34 slides to the calibration scale. After the T-shaped slider 31 stops sliding, press the pull handle 47 downward, and press the cylinder 44 downward to make sure that it is in a fixed position. The squeezing spring 46 and the cylinder 44 move downward, and the V-shaped elastic sheet 482 is compressed while moving downward. The V-shaped elastic sheet 482 is compressed and presses the squeezing block 41 against one side of the slide bar 21, so that the T-shaped slider 31 can be positioned at the corresponding position. As the cylinder 44 moves downward, the turning point of the V-shaped elastic sheet 482 moves to the inside of the arc-shaped slot 45 to prevent the cylinder 44 from being bounced upward. After the scale is recorded, the pulling handle 47 is pulled upward to pull the cylinder 44 upward, and the turning point of the V-shaped elastic sheet 482 is pulled out of the arc-shaped slot 45. When the V-shaped elastic sheet 482 is pulled out of the groove on one side of the squeezing block 41, the squeezing block 41 and the slide bar 21 are loosened, and the T-shaped slider 31 can be slid to reset.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
