Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, and more specifically to a multi-purpose length measuring device. Background Art

[0002] Length measurement can be seen everywhere in many fields. The most common method is to measure objects directly with a ruler. Quality inspectors usually need to inspect the dimensions of processed workpieces to measure whether their dimensions meet the requirements of the drawings. Common rulers or vernier calipers have a single measurement effect, and the measuring tools need to be replaced many times during measurement, which increases the workload of operators.

[0003] Based on the above, the inventors have found that: when measuring the workpiece, due to the wide variety of length measurements, multiple length measuring tools need to be used. This may increase the labor intensity of the operator and the measurement error after long-term use, resulting in workpiece size measurement errors. Therefore, in view of this, the existing structure is studied and improved to provide a multi-purpose length measuring device, in order to achieve a more practical purpose. Utility Model Content

A tightening knob 14 is slidably connected inside the clamping block 7, and limiting blocks 15 are fixedly welded to the bottom of both sides of the tightening knob 14. Rubber blocks are fixedly connected to the outside of the two limit blocks 15. Several rollers 11 are rotatably connected inside the two grooves 10, which facilitates the grooves 12 to slide on the surface of the rollers 11, thereby improving the operability of the device.

[0028] See also Figure 1 The bottom of the slider 6 is flush with the bottom of the protective shell 1, and scales are respectively set on both sides of the top of the movable plate 2; the center end of one side of the push plate 5 is fixedly connected to one side of the movable plate 2 by bolts, and the gap between the two baffles 3 is smaller than the width of the push plate 5; the inner side of the clamping block 7 is on the same horizontal line with the other side of the protective shell 1, and one side of the movable plate 2 is on the same horizontal line with one side of the protective shell 1. For large items, it is not convenient to carry. The movable plate 2 is slid from one side of 1, and then the inner side of the slider 6 is close to one side of the item. The item is clamped by the slider 6 and the fixed plate 4, and the length of the item can be obtained from the top scale of the movable plate 2. For small items, they can be directly placed on the top of the protective shell 1, and the item is clamped by the clamping block 7 and the baffle 3, and the length of the item can be obtained from the top scale of the movable plate 2.

[0029] See also Figure 2 , Figure 3 The bottom of the two through grooves 8 is flush with the inner bottom of the protective shell 1, and the height of the groove 10 is consistent with the height of the slide groove 12; the gap between the two baffles 3 is smaller than the width of the clamping block 7, and the two protrusions 9 are tightly fitted to the bottom of the moving plate 2 and the top of the limiting plate 13. By setting 8, it is convenient to clean the inside of the protective shell 1. The two protrusions 9 are between the moving plate 2 and the limiting plate 13, which is convenient for the sliding of the moving plate 2. The width of the clamping block 7 is greater than the gap between the two baffles 3, which prevents the moving plate 2 from sliding out of the track, and is highly practical.

[0030] See also Figure 4The two limit blocks 15 are located below the groove 10, and the bottom of the tightening knob 14 is at the same height as the bottom of the two protrusions 9.
