Abstract

The utility model relates to a tip depth vernier caliper and belongs to the metering too field. The tip depth vernier caliper comprises a main ruler and a measuring rod. The tip depth vernier caliper is characterized in that the measuring rod is in the shape of a tip. The tip depth vernier caliper can fully approach a recess position to be measured, realizes accurate measuring of recess depth and meets requirements of field use.

Description

The tip vernier depth gauge

Technical field:

The utility model relates to a kind of tip vernier depth gauge, belongs to the measurement instrument field.

Background technology:

Vernier depth gauge is checking tool indispensable in the quality control process, use is extensive and frequency is high, it is the effective tool of the meter planar defect degree of depth, the depth gage of market sale is unsuitable for the production reality of shaped steel, the square that the surveying work face of original vernier caliper measuring staff is, and the surveying work face is larger, be not suitable for measuring the degree of depth of tiny defect, the degree of depth that can't the Measurement accuracy defective namely can't be visited the end, extremely affects inspectoral correct judgement, thus correct operative norm.

Summary of the invention:

In view of the above problems, the purpose of this utility model is to provide a kind of tip vernier depth gauge, can realize the cup depth measurement accurately fully near measured defective locations, satisfies the on-the-spot requirement of using.

to achieve these goals, the technical scheme that the utility model is taked is the tip vernier depth gauge, include main scale, sounding rod, its design feature is that sounding rod is inserted in the middle of the swallowtail shape slot of main scale, be flexible connection with main scale, the swallowtail shape slot can be connected to sounding rod on main scale accurately, be not easy to come off, sounding rod hypomere front is triangular pointed, with the main scale surface of contact be one section inclined-plane of hypomere, the sounding rod lower surface is square, because sounding rod hypomere of the present utility model is pointed shape, so in use can visit the end, the degree of depth of Measurement accuracy defective, middle part, main scale lower end has a spill mouth, there is a fixed knob in the main scale stage casing, be equipped with one in gap between fixed knob and sounding rod and compress shell fragment.

Description of drawings:

Fig. 1 is front elevation of the present utility model;

Fig. 2 is A-A position, side of the present utility model partial sectional view;

Fig. 3 is vertical view of the present utility model.

Embodiment:

accompanying drawing provides a kind of embodiment of the present utility model, below in conjunction with accompanying drawing, the technical solution of the utility model is made a detailed description: the tip vernier depth gauge that the utility model provides, include main scale (1), sounding rod (2), its design feature is that sounding rod (2) is inserted in the middle of the swallowtail shape slot (6) of main scale (1), be flexible connection with main scale (1), sounding rod (2) hypomere front is triangular pointed, with main scale (1) surface of contact hypomere be one section inclined-plane, sounding rod (2) lower surface (5) is square, area can be 0.2mm * 0.2mm, middle part, main scale (1) lower end has a spill mouth, there is a fixed knob (3) in main scale (1) stage casing, be equipped with one in gap between fixed knob (3) and sounding rod (2) and compress shell fragment (4), during measurement, unscrew fixed knob (3), pull-up sounding rod (2), main scale (1) is placed on measured, press sounding rod (2), make most advanced and sophisticated near measured defective, infer at last gauge rod (2), make most advanced and sophisticated and testee close contact, knob (3) is tightened, read the data shown in scale.

Claims

1. tip vernier depth gauge, include main scale, sounding rod is characterized in that sounding rod is inserted in the middle of the swallowtail shape slot of main scale, is flexible connection with main scale, sounding rod hypomere front is triangular pointed, with main scale surface of contact hypomere be one section inclined-plane, the sounding rod lower surface is square, middle part, main scale lower end has a spill mouth, there is a fixed knob in the main scale stage casing, is equipped with one in the gap between fixed knob and sounding rod and compresses shell fragment.
