Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a hardware size measuring device. Background Art

[0002] Hardware: Traditional hardware products, also known as "small hardware", refer to five metals: gold, silver, copper, iron, and tin. They can be made into works of art or metal devices such as knives and swords through manual processing. When processing precision hardware, its external dimensions need to be measured and inspected. The existing inspection method is generally that a worker holds the hardware in hand and another worker holds a measuring device in hand to measure it. On the one hand, when the worker is measuring, it is easy for the ruler to not align with the hardware, affecting the accuracy. On the other hand, when measuring the hardware, the worker needs to hold the hardware in hand for a long time, which can easily cause the worker's palm to be cut by the sharp part of the hardware, causing safety accidents.

[0003] In the prior art, the Chinese utility model with publication number: CN219829691U discloses a device for detecting the external dimensions of precision hardware, which relates to the field of hardware processing technology, including a base, two support frames for support are fixedly installed on the lower surface of the base, and a scale for measuring the external dimensions of the hardware is fixedly installed on one side of the upper surface of the base. In the utility model, the staff places the hardware to be measured and tested on the base, and the staff turns the hand wheel to drive the bidirectional threaded rod to rotate. The rotating bidirectional threaded rod drives the two sliders and the clamping plate to move along the side groove direction by screwing in the thread, so that the two clamping plates clamp and fix the hardware. Then the staff can record the scale value aligned on one side of the clamping plate to measure the external dimensions of the hardware. With the cooperation of the clamping plate and the scale, the staff does not have to hold the hardware in one hand and the measuring device in the other hand for measurement.

[0004] Although the above technical solution can perform fixed measurement on hardware, the hardware placed on the base may be affected by the side grooves and may be displaced during measurement. At the same time, bidirectional fixation may cause the hardware to shift at the moment of clamping. Although the reading value is convenient for viewing through a magnifying glass, it requires bidirectional reading, and calculation is required after reading the value, which reduces the efficiency of measurement. Therefore, we need to propose a hardware size measuring device. Utility Model Content
