[0020] like Figures 1 to 4As shown, this utility model discloses a steel tape measure calibration device for easy reading, comprising an operating table 1, a moving mechanism 2, a mounting frame 3, and a calibration mechanism 4.

A second fixing mechanism is provided at the top right end of the operating table 1. When inspection is required, firstly, one end of the steel tape measure is placed on the first placement plate, and then the first screw is rotated so that the first pressure plate slides through the first slider until the bottom of the first pressure plate and the top of the tape measure are in close contact. Then, the operator adjusts the position of the second fixing mechanism, pulls the steel tape measure, and fixes it with the second fixing mechanism. Finally, the moving mechanism is started, and the mounting frame drives the inspection mechanism to start inspecting the steel tape measure. This allows the operator to quickly inspect steel tape measures of different specifications and lengths, thereby improving the convenience of the device and enhancing its practicality.

[0021] In a preferred embodiment of the above, the second fixing mechanism includes a second placement plate 11, two sets of hinge seats 12, a connecting block 13, a support plate 14, a fixing plate 15, a fixing block 16, a second pressure plate 17, a limiting component, an adjusting component, and a buffer component. The top right end of the operating table 1 is connected to the bottom of the second placement plate 11 via the adjusting component. The top right end of the second placement plate 11 is hinged to the bottom of the connecting block 13 via the two sets of hinge seats 12. The top of the connecting block 13 is connected to the rear end of the bottom of the support plate 14. The top front end of the second placement plate 11 is connected to the bottom of the fixing plate 15. The top of the fixing plate 15 is connected to the support plate 14 via the limiting component. The front end is tightly attached, the bottom of the support plate 14 is connected to the top of the fixing block 16, and the bottom of the fixing block 16 is slidably fitted through the buffer component and the top of the second pressure plate 17. The adjustment component is activated, the second placement plate is slid to the appropriate position, and then the steel tape measure is pulled so that the other end of the steel tape measure strip is placed on the second placement plate. Then the support plate is flipped, and the support plate is hinged through the connecting block and the hinge seat, causing the bottom of the second pressure plate and the top of the tape measure strip to be tightly attached.

The second slider 19 is slidably connected to the slide groove of the operating table 1. The top of the second slider 19 is connected to the bottom of the second placement plate 11. When the drive mechanism is started, the output end of the drive mechanism drives the second screw to start rotating. The second slider starts to drive the second placement plate to slide until it slides to the appropriate position, thereby realizing the automatic adjustment of the position of the steel tape measure, further improving the convenience and accuracy of the calibration process, and thus enhancing its practicality.

[0023] As a preferred embodiment of the above, the limiting component includes a third slider 21, a first spring 22, a pull rod 23, and a positioning block 24. The top of the fixing plate 15 is provided with a sliding groove, and the third slider 21 is slidably connected to the sliding groove of the fixing plate 15. A reserved hole is provided at the left end of the sliding groove of the fixing plate 15, and the right end of the pull rod 23 passes through the reserved hole and is connected to the left end of the third slider 21. The first spring 22 is provided on the outside of the pull rod 23. The top of the third slider 21 is connected to the bottom front end of the positioning block 24, and the bottom rear end of the positioning block 24 is slidably attached to the top of the support plate 14. When the operator pulls the pull rod, the third slider drives the positioning block to slide, and at the same time, the first spring is compressed, thereby limiting the support plate and enhancing its practicality.

[0024] As a preferred embodiment of the above, the buffer assembly includes multiple sets of damping rods 25 and multiple sets of connecting springs 26. The bottom of the fixing block 16 is provided with a groove, and the top of the groove of the fixing block 16 is uniformly connected to the top of the multiple sets of damping rods 25.

A set of connecting springs 26 is provided on the outer side of each of the multiple sets of damping rods 25, and the top of the second pressure plate 17 and the groove of the fixing block 16 are slidably fitted together. By extending and retracting the multiple sets of damping rods and multiple sets of connecting springs, wear on the ruler strip caused by compression can be effectively reduced, thus enhancing its practicality.

[0025] As a preferred embodiment of the above, it also includes two sets of rotating handles 27, with one set of rotating handles 27 respectively provided on the top of the first screw 8 and the left end of the pull rod 23; this allows the operator to quickly rotate the first screw or pull the pull rod, thus enhancing practicality.

This ensures that the steel tape measure can be placed along a predetermined trajectory, avoiding bending or twisting. This is crucial for maintaining measurement accuracy and thus enhances practicality.

[0027] As a preferred embodiment of the above, it also includes two sets of sponge pads 29, with the bottom of the first pressure plate 9 and the second pressure plate 17 respectively connected to the top of a set of sponge pads 29; this can effectively reduce the wear on the ruler strip caused by squeezing friction, thus enhancing practicality.

[0028] This utility model discloses a steel tape measure calibration device for easy reading. Its working principle is as follows: When calibration is required, firstly, one end of the steel tape measure strip is placed on the first placement plate. Then, by rotating the handle, the first screw is rotated, causing the first pressure plate to slide through the first slider until the bottom of the first pressure plate and the top of the tape measure strip are in close contact. Next, the operator activates the drive mechanism, which drives the second screw to rotate, causing the second slider to slide the second placement plate until it reaches the appropriate position. Then, the steel tape measure is pulled, securing the other end of the tape measure strip onto the second placement plate. The support plate is then flipped, hinged by a connecting block and a hinge seat, causing the bottom of the second pressure plate and the top of the tape measure strip to be in close contact. The pull rod is then released, and the first spring rebounds, causing the third slider to slide the positioning block until the bottom of the positioning block and the top front end of the support plate are in close contact, thus completing the fixing process. Finally, the moving mechanism is activated, and the mounting frame drives the calibration mechanism to begin testing the steel tape measure strip.
