Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to shown in Fig. 1 to Fig. 3, according to embodiment of the present utility model, provide a kind of inside diameter measurement instrument.This inside diameter measurement instrument comprises detection piece 10 and protector 20, wherein, detection piece 10 is for measuring the aperture of the through hole of object under test 100, protector 20 is arranged on the periphery of detection piece 10, detection piece 10 is protected, strengthen the intensity of inside diameter measurement tool body, avoid detection piece 10 in moving process, wear and tear or damage, improved the serviceable life of inside diameter measurement instrument.
In the present embodiment, protector 20 comprises protection cylinder portion 21, and detection piece 10 is arranged in the internal cavities of protection cylinder portion 21, and detection piece 10 is implemented to safeguard function.
Refer again to shown in Fig. 2, protector 20 also comprises cover plate portion 22, and this cover plate portion 22 is arranged on the first end of protection cylinder portion 21, and in cover plate portion 22, is provided with the threaded hole 23 being communicated with internal cavities; Inside diameter measurement instrument also comprises screw rod 30, and this screw rod 30 is located in threaded hole 23, and the first end of this screw rod 30 is connected with detection piece 10, during use, can make detection piece 10 stretch out protection cylinder portion 21 by rotary screw 30, and then realize its measurement function.Preferably, the end away from detection piece 10 of screw rod 30 is provided with stop block 40, by the effect of stop block 40, can prevent screw rod 30 landing from threaded hole 23, improves reliability and the security of the inside diameter measurement instrument of the present embodiment.
Preferably, detection piece 10 in the present embodiment comprises a plurality of go-no go gauges 11, the plurality of go-no go gauge 11 is fixedly connected sequentially, and the range of a plurality of go-no go gauges 11 is along successively decreasing away from the direction of cover plate portion 22, use the inside diameter measurement instrument of the present embodiment, can measure the different through hole in multiple aperture, simple in structure, be easy to carry.
Preferably, the center line of the threaded hole 23 in the present embodiment overlaps with the center line of protection cylinder portion 21, guaranteeing that detection piece 10 can reduce the volume of the internal cavities of protection cylinder portion 21 swimmingly stretching out to realize its measurement function from protection cylinder portion 21 when, and then reduce whole inside diameter measurement instrument volume, be easy to carry and carry.
