Abstract
The utility model discloses a vernier caliper, which comprises a main scale and a vernier, wherein the main scale is provided with outer measuring jaws, inner measuring jaws and a depth indicator, wherein one sides of the inner measuring jaws, which are used for measurement, are provided with chutes, and the chutes are provided with measuring pins. As the technical scheme is adopted, the two measuring pins are enabled to slide out of the inner measuring jaws and extend into holes to carry out the measurement. The vernier caliper disclosed by the utility model is capable of measuring the minor-diameter holes into which the inner measuring jaws cannot extend. The method is simple and fast, the use is convenient and the measuring accuracy is high.
Description
Technical field
The utility model relates to a kind of vernier caliper, relates in particular to a kind of vernier caliper of surveying the small-bore.
Background technology
Interior measuring claw generally is housed on the existing vernier caliper, it is very convenient when measuring claw is used for measuring the aperture in described, but when measuring less hole, some apertures, because the size of interior measuring claw itself is bigger than the diameter of measured hole, interior measuring claw can't stretch in the hole, and the size of this aperture can't accurately be measured, and general the employing estimated or estimation, can't guarantee precision, and never have the size that suitable survey instrument is accurately measured this aperture on the market now.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of vernier caliper that can measure the small-bore is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vernier caliper, comprise main scale and the vernier that is installed on the described main scale, and described main scale is provided with measuring claw in first, and described vernier is provided with measuring claw in second; The measurement limit of the measuring claw and the second interior measuring claw is provided with chute in described first, is slidingly fitted with surveyingpin in the described chute.
As a kind of improvement, described interior measuring claw is provided with upper limit position block and the lower position block that limits described surveyingpin position.
As a kind of improvement, described surveyingpin is provided with locking device.
Owing to adopted technique scheme, the utility model can stretch into surveyingpin in the hole and measure by surveyingpin being skidded off outside the interior measuring claw, it is less that the utility model can be measured diameter, and interior measuring claw can't stretch into the hole in the hole, the method simple and fast, easy to use, the measuring accuracy height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the first interior measuring claw among Fig. 1;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the sectional view at A-A place among Fig. 2;
Among the figure: the 100-main scale; Measuring claw in the 200-; The 300-vernier; The 201-surveyingpin; The 202-chute; The 203-upper limit position block; The 204-lower position block; The 205-check nut.
Embodiment
As shown in Figure 1, present embodiment comprises main scale 100 and the vernier 300 that is installed on the described main scale 100, and described main scale is provided with measuring claw in first, and described vernier is provided with measuring claw in second;
Shown in Fig. 2, Fig. 3 and Fig. 4 are common, in described first in the measuring claw and second the measurement limit of measuring claw be provided with chute 202, be slidingly fitted with surveyingpin 201 in the described chute 202.Measuring claw 200 is provided with upper limit position block 203 and the lower position block 204 that limits described surveyingpin 201 positions in described.
Described surveyingpin 201 is provided with locking device, and in the present embodiment, described locking device is a check nut 205.
Owing to adopted technique scheme, the utility model can stretch into surveyingpin in the hole and measure by two surveyingpins being skidded off outside the interior measuring claw, it is less that the utility model can be measured diameter, and interior measuring claw can't stretch into the hole of measuring in the hole, method simple and fast, easy to use, the measuring accuracy height.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
