Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a depth vernier caliper disclosed in an embodiment of the present invention includes a caliper body 1. The ruler body 1 is provided with a vernier 2 in a sliding way. The vernier 2 is sleeved on the ruler body 1, so that the vernier 2 can slide along the length direction of the ruler body 1. The vernier 2 is symmetrically hinged with a support lug 3, and the rotation plane of the support lug 3 is parallel to the plane of the vernier 2. When the supporting ear 3 rotates to be vertical to the ruler body 1, the side surface of the supporting ear 3 is flush with the end surface of the vernier 2. The positioning piece is arranged on the vernier 2, and the positioning piece can fix the position of the vernier 2 on the ruler body 1, so that the vernier 2 cannot move. Scales are arranged on the ruler body 1 and the vernier 2.

When carrying or depositing, the staff rotates two support ears 3 for support ears 3 gather together towards the direction of being close to blade 1, makes support ears 3 and blade 1 be in the state that is parallel to each other, has reduced the size in shared space. When in use, the supporting ear 3 is rotated to be vertical to the ruler body 1.

Referring to fig. 1, the blade 1 includes a first blade 11 and a second blade 12 that are removably connected together. One end of the first ruler body 11 close to the second ruler body 12 is integrally formed with a threaded head 111, and one end of the second ruler body 12 close to the first ruler body 11 is provided with a threaded hole matched with the threaded head 111. The first blade 11 and the second blade 12 can be threaded together with the threaded head 111 and threaded hole.

When the ruler is carried or stored, the first ruler body 11 and the second ruler body 12 are separated and overlapped together, and then the two supporting ears 3 are rotated to be parallel to the ruler body 1. Accomodate the completion after, the utility model discloses a whole length all diminishes with longitudinal span, has reduced shared space. The first ruler body 11 and the second ruler body 12 are in threaded connection, the structure is simple, and the connection is convenient and fast.

Referring to fig. 1 and 2, the positioning member is provided as a fastening screw 4. A threaded hole is formed in the side surface of the cursor 2 so that the fastening screw 4 is screwed on the cursor 2. The fastening screw 4 can penetrate through the vernier 2 along the threaded hole and abut on the blade 1.

When the vernier 2 needs to be moved, the fastening screw 4 is rotated, so that the fastening screw 4 is separated from the ruler body 1. When the vernier 2 needs to be fixed, the fastening screw 4 is rotated, so that the end face of the fastening screw 4 is tightly abutted against the ruler body 1, and the vernier 2 is fixed on the ruler body 1.

Referring to fig. 2, in order to facilitate the use of the worker and reduce the operation difficulty, a protrusion 31 is fixedly disposed at one end of the support lug 3 close to the hinge shaft. The supporting ear 3 is rotated, when the projection 31 is abutted on the vernier 2, the supporting ear 3 and the ruler body 1 are kept perpendicular to each other.

Further, referring to fig. 2, in order to make the supporting ear 3 more firmly rotated to be perpendicular to the blade 1, a first magnet 51 is embedded in the protrusion 31, and a second magnet 52 is embedded in both sides of the cursor 2. When the bump 31 abuts against the cursor 2, the first magnet 51 and the second magnet 52 are attached together, and the first magnet 51 and the second magnet 52 are attracted to each other under the action of attraction of opposite magnetic poles.

Referring back to fig. 1, in order to enable the first blade 11 and the second blade 12 to be connected together when separated, a fixing clip 13 is integrally formed at one end of the second blade 12 facing away from the threaded hole. The fixing clip 13 is of a C-shaped structure, is made of rigid materials and has certain elasticity, so that the first ruler body 11 can be clamped on the fixing clip 13 when the first ruler body 11 is separated from the second ruler body 12.

Further, referring to fig. 1, a hanging rope 14 is fixedly disposed on the fixing clip 13 for the convenience of carrying by the worker.

The implementation principle of the embodiment is as follows: when stored, the first blade 11 and the second blade 12 are rotated apart. The support ears 3 are rotated so that the two support ears 3 converge toward the blade 1. The first blade 11 is clamped to the retaining clip 13 so that the first blade 11 and the second blade 12 overlap.

In use, the first blade 11 is removed from the retaining clip 13 and the threaded head 111 is screwed into a threaded hole in the second blade 12. The two support lugs 3 are rotated so that the projection 31 abuts on the cursor 2, and the first magnet 51 and the second magnet 52 are attracted to each other to fix the support lugs 3.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
