Description

Technical Field

[0001] The utility model belongs to the field of measurement technology, in particular to a portable multi-purpose go / no-go gauge. Background Art

[0002] Go and no-go gauges are a type of gauge. They serve as a measurement standard and are used to inspect large quantities of products. In actual production, measuring large quantities of products individually with measuring instruments (such as vernier calipers, micrometers, and other graduated instruments) is tedious. Qualified products have a specific measurement range, and those within this range are considered qualified. Therefore, go and no-go gauges are used for measurement.

[0003] Currently, go / no-go gauges for measuring diameters are processed according to the actual size of the hole and then tested. However, one go / no-go gauge can only measure holes of one diameter. When faced with multiple holes of different diameters, a bunch of go / no-go gauges need to be prepared, which is troublesome to manage or carry. Summary of the Invention

When pressed, the trigger block drives the trigger rod to move downward, and the first elastic element is used to reset the trigger rod;

[0007] The trigger end also includes a measuring part, which includes several go / no-go gauges for detecting diameters and several pressure blocks. The go / no-go gauges and the pressure blocks are connected by a second elastic element. Several third elastic elements are also provided between the pressure blocks and the casing body. The third elastic elements are used to reset the pressure blocks.

[0008] Furthermore, one end of the second elastic element is fixedly connected to the pressing block, and the other end is fixedly connected to the go / no-go gauge.

[0009] Furthermore, a guide slope is provided on one side of the circumference of the go / no-go gauge, a matching slope is provided on the inner surface of the housing body, the go / no-go gauge enters the housing body outlet along the slope, and the head of the go / no-go gauge is provided with detection heads of different diameters.

[0010] Furthermore, a through hole is provided on the housing body, and a number is engraved on the trigger end, the number being the diameter size of the detection head, and the number is exposed through the through hole.

[0011] Furthermore, a bearing is provided in the housing body, and the bearing is used for the rotation of the limit block.

[0012] Beneficial effects of the utility model:
