Caliper

Abstract

To provide a caliper that simplifies the configuration for creating a protrusion on the jaws. [Solution] The pair of first jaws 23 and second jaws 24 have screw holes 23c and 24c formed along the longitudinal direction L of the main scale 21, which open to the inner surfaces 23a and 24a and have internal threads F formed on the inner circumferential surface. Bolts 25b and 26b are fitted into these screw holes 23c and 24c, and a portion of the bolts 25b and 26b protrudes from the inner surfaces 23a and 24a, thereby forming the first protrusion 25 and the second protrusion 26. In this way, the configuration for providing the first protrusion 25 and the second protrusion 26 on the first jaw 23 and the second jaw 24 can be simplified.

Claims

1. The main length extends in the longitudinal direction, A slider is attached to the main scale so as to be slidable along the longitudinal direction, It comprises a pair of jaws that protrude from the main scale and the slider, respectively, in a short direction perpendicular to the longitudinal direction, with their inner surfaces facing each other, A caliper characterized in that at least one of the pair of jaws has a screw hole formed along the longitudinal direction, opening to at least the inner surface and having an internal thread on its inner circumferential surface.

2. The bolt has a shaft portion with external threads formed on its outer surface, The caliper according to claim 1, characterized in that a protrusion is formed from the inner surface of the jaw by a part of the bolt in which the male thread of the shaft portion is fitted into the female thread of the screw hole.

3. The screw holes are opened on the outer surface of the jaw opposite to the inner surface in the longitudinal direction, and on the inner surface, respectively. The bolt has a head that protrudes outward from one end of the shaft in a direction perpendicular to the axis, The caliper according to claim 2, characterized in that the head is pressed against the outer surface by an axial force while the male thread of the shaft is fitted into the female thread of the screw hole.

4. The screw hole has a bottom surface on the side opposite to the inner surface in the longitudinal direction, and opens only to the inner surface. The bolt has a head that protrudes outward from one end of the shaft in a direction perpendicular to the axis, The caliper according to claim 2, characterized in that, when the male thread of the shaft is fitted into the female thread of the screw hole, the other end of the shaft is pressed against the bottom surface of the screw hole by an axial force.

5. The caliper according to any one of claims 1 to 4, characterized in that the jaws are provided with a plurality of different types of screw holes arranged in the short direction.

6. The main length extends in the longitudinal direction, A slider is attached to the main scale so as to be slidable along the longitudinal direction, A pair of jaws, each extending from the main scale and the slider in the short direction perpendicular to the longitudinal direction, with their inner surfaces facing each other, A bolt having a shaft portion inserted into a through hole that penetrates the longitudinal direction of at least one of the pair of jaws, The system includes a nut that is fitted onto the shaft portion to secure the bolt to the jaw, A caliper characterized in that a protrusion is formed on the inner surface of the jaw by a part of the bolt fixed to the jaw with the nut.

7. The main length extends in the longitudinal direction, A slider is attached to the main scale so as to be slidable along the longitudinal direction, A pair of jaws, each extending from the main scale and the slider in the short direction perpendicular to the longitudinal direction, with their inner surfaces facing each other, The device comprises a shaft member which is press-fitted into a through hole that penetrates the longitudinal direction of at least one of the pair of jaws, A caliper characterized in that a portion of the shaft member, which is press-fitted into the through hole, forms a protrusion that extends from the inner surface of the jaw.
