Preferably, the main scale is located in the middle of the base.

Preferably, the base is detachably connected to the bottom of the main scale.

Preferably, the base is provided with a through groove matched with the main scale, the side surface of the base is in threaded connection with a locking bolt, the locking bolt can be screwed into the through groove, and the base and the main scale are fixed through the locking bolt.

Preferably, the cross section of the base is in a convex shape with a narrow top and a wide bottom, the locking bolt is connected with the side face of the narrow side of the base, and when the locking bolt is screwed, the locking bolt abuts against the narrow side face of the main scale.

Through the technical scheme, the utility model discloses a degree of depth slide caliper, this degree of depth slide caliper have increased the width of main scale bottom through add a base in the bottom of main scale to improve the stability at the measurement of depth, improved the measuring degree of accuracy.

Other features and advantages of the present invention will be described in detail in the detailed description which follows.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Referring to fig. 1 and 2, the present embodiment discloses a depth vernier caliper, which includes a main scale 1, a depth scale 2, a vernier 3 and a base 4. The main scale 1, the depth scale 2 and the vernier scale 3 are conventional installation methods of vernier calipers in the prior art, and are not described herein.

Depth scale

2 and 3 fixed connection of vernier scale, vernier scale 3 can drive depth scale 2 from the bottom roll-off of main scale 1, and base 4 sets up in the bottom of main scale 1, and the bottom surface of base 4 flushes with the bottom surface of main scale 1, and the width of base 4 is greater than the width of main scale 1, and base 4 is provided with the through-hole that supplies depth scale 2 roll-off. When measuring, because the reason of base 4, the width increase of main scale 1 bottom, when measuring the degree of depth, have sufficient width surplus to supply the staff to operate the measurement, the condition of rocking appears when having avoided measuring, has improved the measuring degree of accuracy. Preferably, the main scale 1 is located in the middle of the base 4, so that when the width of the barrel or the groove is small, the base 4 can be spanned at the top of the barrel or the groove, two ends of the base 4 are respectively lapped at the top of the barrel wall or the groove wall, and the measurement is more accurate.

Referring to fig. 1-3, the base 4 is detachably connected to the bottom of the main scale 1, so that the base 4 can be detached to improve the applicability of the vernier caliper under the condition that the depth does not need to be measured. Referring to fig. 2, a through groove 5 matched with the main scale 1 is formed in the base 4, a locking bolt 6 is connected to the side face of the base 4 in a threaded manner, the locking bolt 6 can be screwed into the through groove 5, and the base 4 and the main scale 1 are fixed through the locking bolt 6. In this embodiment, the cross-section of the base 4 is in a convex shape with a narrow top and a wide bottom, so that the depth of the threaded hole and the length of the locking bolt 6 can be reduced, and the process difficulty is reduced. The locking bolt 6 is connected with the side surface of the narrower side of the base 4, and when the locking bolt 6 is screwed tightly, the locking bolt abuts against the narrower side surface of the main scale 1. That is, the lock bolt 6 abuts on the side of the main scale 1 indicating the thickness, and damage of the lock bolt 6 to the main scale 1 during locking is reduced.

Through the technical scheme, the utility model discloses a degree of depth slide caliper, this degree of depth slide caliper have increased the width of main scale 1 bottom through add a base 4 in the bottom of main scale 1 to improve the stability at the measurement of depth, improved the measuring degree of accuracy.
