Description

Vernier caliper

Technical Field

The utility model relates to a measurement technique, concretely relates to can measure slide caliper of minor diameter inner groove aperture size.

Background

The vernier caliper has the advantages of simple structure, wide application and convenient use, can meet the measurement requirement of general precision, and is widely applied to the production of various industries; taking a vernier caliper with a measuring range of 0 to 150mm as an example, the conventional vernier caliper is composed of a main scale and a vernier assembly capable of sliding on the main scale, wherein an inner measuring claw and an outer measuring claw are respectively arranged on the main scale and the auxiliary scale and are used for measuring the inner diameter and the outer diameter.

However, in some structures having arc-shaped grooves, the positions of the grooves are hidden, the space is narrow, the size of the grooves is difficult to measure, and the measurement range and the width of the clamping tip of the conventional inner groove caliper are not practical for measuring the size of the inner grooves, so that a vernier caliper which can be used for measuring the size of the inner grooves with small diameters and is simple and convenient to use is needed.

Disclosure of Invention

The purpose of the invention is as follows: the utility model provides a measure slide caliper of slot size in minor diameter for solve the narrow and small slot in space and be difficult to the measuring problem.

The technical scheme is as follows:

in order to achieve the purpose, the invention provides the following technical scheme:

the vernier caliper comprises a main scale with scale marks, a vernier caliper arranged on the main scale in a sliding mode, an outer measuring claw and an inner measuring claw which are arranged on one end of the vernier caliper, and a depth gauge arranged at the other end of the vernier caliper.

Preferably, the inner measuring claw is provided with a groove, and the groove is used for extending into the groove to be measured.

Preferably, the height of the clamping head is 0.7mm, and the width of the clamping head is 1.5 mm; the height of the groove is 12.8mm, and the width is 1.5 mm.

Has the advantages that:

the utility model provides a slide caliper is through supplementing processing to standard slide caliper, reforms transform interior measuring card point, under the prerequisite that does not change current measuring range, can use in the measurement of minor diameter inner groove hole.

The utility model provides a vernier caliper has solved the measurement problem of minor diameter inner groove hole to the measuring tool is simple and convenient, and the transformation method is simple, practices thrift the cost.

fig. 2 is an enlarged view of the jaw of the vernier caliper.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, which refer to fig. 1 to 2.

As shown in fig. 1-2, the utility model provides a vernier caliper's structure chart for measure the diameter size of interior slot, including the main scale that has the scale sign, slide and locate vernier scale on the main scale, locate outer measuring jaw and interior measuring jaw on vernier caliper one end, and locate the depth gauge of the vernier caliper other end, disassemble standard vernier caliper, carry out the processing of benefit to the blade, the interior bayonet catch of chi claw, make interior measuring jaw be equipped with the groove part, be equipped with convex dop on the interior measuring jaw, the height of dop is 0.7mm, and the width is 1.5 mm; the height of the groove is 12.8mm, and the width is 1.5 mm.

Claims (3)

1. The vernier caliper comprises a main scale with scale marks, a vernier caliper arranged on the main scale in a sliding mode, an outer measuring claw and an inner measuring claw which are arranged on one end of the vernier caliper, and a depth gauge arranged at the other end of the vernier caliper.

2. A vernier caliper as claimed in claim 1, wherein said inner measuring jaw is provided with a recess for extending into the groove to be measured.
