With the development of the industrial society, various vernier calipers meet different measurement requirements, and various vernier calipers can finish the measurement of objects with different shapes, thereby bringing great convenience to accurate measurement.

However, although the above vernier caliper brings great convenience in measurement, when the length and the concave depth of a concave object are required to be measured when the concave object with different concave depths is encountered, a vernier caliper specially used for measuring the concave portion is required to be used. And if the concave depth difference is large, the groove vernier calipers with different specifications are replaced, and the measuring working efficiency is influenced.

In order to improve the above technical problem, the following embodiments provide a multifunctional measuring jaw vernier caliper.

Referring to fig. 1 and fig. 2, the present embodiment provides a multi-functional vernier caliper 10, which includes a caliper body 100, a vernier 200, at least one auxiliary component 300, and at least one measuring group 400.

The measuring group 400 comprises two measuring claws 401 respectively arranged on the ruler body 100 and the vernier scale 200; at least one measuring jaw 401 of each measuring group 400 is provided with an auxiliary fitting 300;

The auxiliary fitting 300 is arranged in the measuring group 400 of the multifunctional measuring jaw vernier caliper 10, and the auxiliary fitting can keep an included angle with the measuring surface 402, so that the auxiliary fitting can cooperate with the measuring jaw 401 in the same measuring group 400 to measure the size of the concave part. Meanwhile, the two measuring claws 401 in the same measuring group 400 can measure the size of the plane part only by means of the mutual matching of the respective measuring surfaces 402. Namely, the multifunctional measuring jaw vernier caliper 10 can realize the measurement of a plane part and a concave part, and one measuring tool realizes two measuring modes. In conclusion, the multifunctional vernier caliper 10 can simultaneously measure the plane part and the concave part, and has simple operation mode and high measurement efficiency.

Please refer to fig. 1 to 4 for further details of the multi-function vernier caliper 10.

In the present embodiment, the body 100 of the multi-function vernier caliper 10 includes a main scale 110 and a depth scale 120. The main scale 110 is slidably connected to the vernier 200, and the depth gauge 120 is located at one end of the main scale 110 away from the vernier 200 in the longitudinal direction. The main scale 110 and the vernier scale 200 are fastened by fastening screws.

Further, as can be seen from the figure, the multi-function vernier caliper 10 includes two measurement sets 400, an inner measurement set 400 and an outer measurement set 400. Inner measuring set 400 includes two oppositely disposed inner measuring jaws 410 and outer measuring set 400 includes two oppositely disposed outer measuring jaws 420. The measuring surface 402 of the inner measuring jaw 410 is located on the side of the two measuring jaws 401 facing away from each other, and the measuring surface 402 of the outer measuring jaw 420 is located on the side of the two measuring jaws 401 facing each other.

As can also be seen from fig. 2 and 3, in the present embodiment of the invention, the auxiliary fitting 300 can be flush with the measuring surface 402 of the measuring jaw 401.

The arrangement mode that the auxiliary fitting 300 is flush with the measuring surface 402 enables the measuring surface 402 of the measuring jaw 401 with the auxiliary fitting 300 to be directly used as a surface of a measuring plane in the second state, so that interference of the auxiliary fitting 300 in plane measurement of the measuring jaw 401 is avoided. On the other hand, the manner that the auxiliary fitting 300 is flush with the measurement surface 402 is also beneficial to ensuring the integrity and the flatness of the whole measurement surface 402, that is, in the second state, the surface of the measurement claw 401 on the side of the measurement surface 402 is a complete plane.

It is understood that, in other embodiments of the present invention, in the second state, the auxiliary fitting 300 may also have a preset distance from the measuring surface 402, and such arrangement can ensure that the auxiliary fitting 300 is completely retracted into the measuring jaw 401. This is merely an example and is not limiting.

Further, in the present embodiment of the present invention, the auxiliary fitting 300 can be flush with the surface of the plate 403 of the measuring claw 401.

Therefore, the space utilization rate of the measuring claw 401 is improved, and the overall visual perception is better.

It is understood that in other embodiments, the auxiliary fitting 300 may be a protruding plate 403, as long as the auxiliary fitting 300 can cooperate with the measuring jaw 401 to measure the concave portion, which is merely an example.

Further, at least two auxiliary fittings 300 are arranged on one measuring jaw 401; and the lengths of the auxiliary fittings 300 are different from each other. Such auxiliary fittings 300 can realize the measurement of concave parts with different depths, and the cooperation of the auxiliary fittings 300 with different lengths can adapt to more measurement environments. For example, in the case where a single-side space is narrow and a large length is not suitable, a shorter auxiliary fitting 300 may be used on one side and a longer auxiliary fitting 300 may be used on the other side.

In the present embodiment of the present invention, two auxiliary fittings 300 are disposed on one measuring jaw 401; two auxiliary fittings 300 are provided on both sides of the measuring jaw 401, respectively, in the thickness direction of the measuring jaw 401. The two auxiliary fittings 300 are arranged on the plate surfaces 403 on the two sides of the measuring claw 401, so that the auxiliary fittings 300 can be switched between the first state and the second state conveniently, and the measuring efficiency is improved.

It should be understood that, in other embodiments, the auxiliary fitting 300 may be embedded in the measuring surface 402 of the measuring jaw 401 in the second state, as long as the auxiliary fitting 300 can cooperate with the measuring jaw 401 to perform the measurement of the concave portion, which is merely an example and is not limited herein.

Further, the measurement set 400 includes at least one pair of auxiliary members 300; each pair of auxiliary fittings 300 is respectively provided on two measuring jaws 401 in the measuring set 400, and each pair of auxiliary fittings 300 is symmetrically arranged. This arrangement allows each measuring jaw 401 in each measuring group 400 to function as a concave portion measuring tool using the auxiliary fitting 300.

It is understood that in other embodiments of the present invention, one measuring jaw 401 in the measuring group 400 may have an auxiliary fitting 300, while the other measuring jaw 401 is not provided with an auxiliary fitting 300. When the size of a concave part needs to be measured, the auxiliary fitting 300 is unfolded and extended into the concave part, and the other measuring claw 401 in the same measuring group 400 abuts against the plane part of the measuring object. This also enables measurement of a single concave portion.

It should be noted that, in the present embodiment, two inner measuring jaws 410 of the multi-function measuring jaw vernier caliper 10 are respectively provided with two oppositely arranged auxiliary fittings 300, and two sides of the thickness of each inner measuring jaw 410 are respectively provided with two auxiliary fittings 300 (respectively named as a first auxiliary fitting 301 and a second auxiliary fitting 302) with different lengths.
