A fixing frame 7 is provided on the top of the fixed plate 3 and the movable plate 6. A fastening screw 10 is embedded inside the fixing frame 7, and a pressure plate 15 is provided at the bottom of the fastening screw 10. The first measuring platform 1 and the second measuring platform 2 are connected to each other. The measuring platform 2 is externally connected to a U-shaped frame 14. A scale plate 28 is installed on the outside of the U-shaped frame 14. A telescopic rod 16 is provided inside the U-shaped frame 14. A spring 17 is provided on the outside of the telescopic rod 16. A pressure plate 15 is provided at the bottom of the spring 17. A top plate 19 is provided at the top of the telescopic rod 16. A pull rod 20 is installed on the top of the top plate 19. An extension plate 21 is provided on the outside of the U-shaped frame 14. A vertical plate 22 is provided at the bottom of the extension plate 21. The vertical plates 22 are symmetrically distributed. A shaft 23 is provided on the inside of the vertical plate 22. Due to the presence of the vertical plate 22, it is convenient to connect the shaft 23 to the extension plate 22. The extension plate 21 is connected to the other two, and the flattening roller 24 is sleeved on the outside of the shaft 23. The top of the extension plate 21 is provided with a push rod 27. The top of the first measuring table 1 and the second measuring table 2 are provided with scale lines 11, and a set of movable clamping structures and a set of immovable clamping and fixing structures are installed on the outside of the first measuring table 1. A U-shaped frame 14 and an auxiliary clamping and quick-limiting structure are installed on the outside of the measuring table structure. The flattening roller 24 structure is installed on the side of the U-shaped frame 14. First, the polyurethane pad to be measured is spread on the outside of the measuring table. To fix one end of the polyurethane pad, twist the fixed clamping structure. Then, twist the other movable clamping structure to press the extrusion plate 9 against the other side of the polyurethane pad. Pull the limiting structure with one hand, and pull the push rod 27 with the other hand to flatten the polyurethane pad using the flattening roller 24 structure. Release the pull rod 20 and press the pressing plate 15 at the top of the limiting structure against the end of the pad. In this way, the operator can obtain accurate values ​​by observing the scale plate 28. The accuracy is high during measurement. After the measurement is completed, remove the polyurethane pad from the measuring structure.

[0029] A sliding groove 5 is provided on the outside of the first measuring platform 1. A slider 4 is provided on the side of the movable plate 6.

A T-shaped groove 13 is provided on the outside of the first measuring platform 1 and the second measuring platform 2. The T-shaped plate 12 is embedded in the inside of the T-shaped groove 13. By installing the slider 4, the sliding groove 5, and the T-shaped plate 12 and the T-shaped groove 13, it is convenient for the movable plate 6 to move outside the first bearing platform, and at the same time, it is convenient for the U-shaped frame 14 to move outside the bearing platform structure.

[0030] The bottom of the fastening screw 10 is provided with a turntable 8, and the other side of the turntable 8 is provided with a pressing plate 9. The top of the pressing plate 15 is provided with a guide post 18, which passes through the U-shaped frame 14. The top of the U-shaped frame 14 is provided with a top plate 19. Due to the installation of the turntable 8, when the fastening screw 10 is tightened, the pressing plate 9 at the bottom will not flip over.

[0031] The first measuring platform 1 has a metal sheet 32 ​​on its exterior, and the second measuring platform 2 has a magnetic absorbing sheet 33 at its bottom. The magnetic absorbing sheet 33 magnetically attracts the metal sheet 32. By installing the metal sheet 32 ​​and the magnetic absorbing sheet 33, the first measuring platform 1 and the second measuring platform 2 can be initially spliced ​​together by strong ferromagnetic attraction.

[0032] The bottom of the first measuring platform 1 and the second measuring platform 2 are provided with threaded grooves 29. The threaded grooves 29 are connected to threaded blocks 30 by threads. The bottom of the threaded blocks 30 is provided with support rods 31. The side of the second measuring platform 2 is equipped with handles 26. The outer side of the second measuring platform 2 is provided with elastic limit blocks 25. Due to the installation of threaded blocks 30 and threaded grooves 29, it is convenient to install the support rods 31 at the bottom of the measuring platform structure by means of threaded connection.

[0033] The U-shaped frame 14 has a positioning groove 35 on its outside. A positioning rod 34 is embedded inside the positioning groove 35. A scale plate 28 is provided on the outside of the positioning rod 34. By installing the positioning rod 34 and the positioning groove 35, it is convenient to install the scale plate 28 on the outside of the U-shaped frame 14, and it is also convenient to replace it when it is damaged.

[0034] The working principle of the polyurethane pad size measuring device is as follows: When using this measuring device, the first measuring platform 1 and the second measuring platform 2 need to be flipped over first. Then, the support rod 31 is taken out, and the threaded block 30 is screwed to connect with the threaded groove 29. In this way, the support rod 31 structure can be installed at the bottom of the measuring platform structure, thereby supporting the measuring platform. However, in order to improve the accuracy of polyurethane pad measurement, the top of the first measuring platform 1 and the second measuring platform 2 is provided with scale lines 11, and a set of movable clamping structures is installed on the outside of the first measuring platform 1. The movable structure includes a slider 4, a moving plate 6, a fixed frame 7, a pressing plate 9, a turntable 8, and a fastening screw 10, and a set of immovable clamping and fixing structures. The movable structure includes a fixed plate 3, a fixed frame 7, a pressing plate 9, a turntable 8, and a fastening screw 10. A U-shaped frame 14 and an auxiliary fastening and limiting structure are installed on the outside of the measuring table structure. The auxiliary limiting structure includes a sliding U-shaped frame 14, a pressing plate 15, a telescopic rod 16, a spring 17, a guide column 18, a top plate 19, and a pull rod 20. A flattening roller 24 structure is installed on the side of the U-shaped frame 14, including an extension plate 21, a vertical plate 22, a shaft 23, and the flattening roller 24. First, the polyurethane pad to be measured is spread on the outside of the measuring table. Then, the fastening screw 10 is turned in the opposite direction to install one end of the polyurethane pad at the corner. The fastening screw 10 is then turned again to tighten it. According to the width of the polyurethane pad, the sliding plate on the side of the movable plate 6 is pulled into the groove. 5. Move the internal parts until the width is determined, then repeat the operation to press and fix the other corner with the clamping plate 15. Then, pull the pull rod 20 with one hand to move the limiting structure, and pull the push rod 27 on the other side to flatten the polyurethane pad by the flattening roller 24. Release the pull rod 20, hold the push rod 27 with the other hand, and pull the shaft 23 at the bottom of the vertical plate 22 to drive the external flattening roller 24 to flatten the pad. After the polyurethane pad is initially flattened, the operator releases the pull rod 20 and presses the clamping plate 15 onto the end of the pad. Since a spring 17 is installed on the top of the clamping plate 15, when the pull rod 20 is released, the clamping plate 15 at the bottom can quickly return to its original position under the elastic force of the spring 17. Personnel can obtain accurate values ​​by observing the scale plate 28 at the top of the scale line 11. The measurement is highly accurate and the operation is relatively simple. After the measurement of the paper roll pad is completed, first pull the lever 20 upward to remove the polyurethane pad from the bottom of the pressure plate 15. Then, tighten the fastening screws 10 to remove it from the bottom of the extrusion plate 9. Finally, when the measuring table is no longer needed, to facilitate the transfer of the measuring table, turn the support rod 31 in the opposite direction to remove it from the bottom of the first measuring table 1 and the second measuring table 2. Then, flip the first measuring table 1 and the second measuring table 2 over so that the magnetic suction plate 33 on the back can magnetically attract the metal plate 32. Then, rotate the elastic limit block 25 to limit the two. Hold the handle 26 to take it away and move it.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
