Description

A multifunctional caliper

technical field

The utility model relates to a measuring tool, in particular to a multifunctional caliper.

Background technique

At present, the widely used calipers are generally composed of main ruler, auxiliary ruler, depth ruler, inner caliper group and outer caliper group. The length of the auxiliary ruler is less than the length of the main ruler. The auxiliary ruler is in a shape that matches the main ruler. It is clamped and tightly attached to the outer wall of the main ruler. Fixed on the main ruler. The depth gauge is installed on the inner wall of the auxiliary ruler and is parallel to the main ruler. There is a groove corresponding to the position and shape of the depth ruler on the outer wall of the main ruler. When the auxiliary ruler moves on the main ruler, the depth ruler remains in this groove and follows with Sub-ruler moves. Such as the following comparison documents:

Reference Document 1 (CN2831040Y) discloses a caliper that can simultaneously measure and write functions and is more convenient to carry. The caliper is a hollow cylinder with a flat scale surface, and the auxiliary ruler is a shape that matches the main ruler, which is clamped and close to the outer wall of the main ruler. The depth ruler is installed on the inner wall of the auxiliary ruler and is parallel to the main ruler. There is a groove corresponding to the position and shape of the depth gauge. When the auxiliary ruler moves on the main ruler, the depth ruler remains in this groove and moves with the auxiliary ruler. There is a pen in the cavity of the main ruler, and the tip of the pen extends out of the main ruler. cavity. The depth gauge can be folded to shorten the length, the outer measuring claws of the main ruler and the auxiliary ruler can be folded to the inner measuring claw position, and a hook is installed on the outer wall position on the back of the auxiliary ruler.

Reference document 2 (CN102865790A) discloses a vernier caliper, which includes a main ruler and a vernier. At the same time, the main ruler is provided with a scale, and a window is opened on the vernier on one side of the scale of the main ruler, and the window is provided with a standard. The window is provided with a convex lens.

Reference 3 (US08966779B2) A bidirectional vernier caliper includes a main scale and a vernier having a sliding channel, wherein the main scale is inserted into it. Since the front and back of the main ruler have scale layers respectively, and the front and rear sides of the vernier are provided with scale layers, the vernier caliper is convenient for left-handed and right-handed users.

In the above three comparison documents, we can find that these calipers only have a single measurement function, but in actual use, it is often necessary to draw a circle and a straight line at the same time. There are many tools, which are inconvenient to carry and easy to miss and lose. Therefore, a single-function caliper can no longer meet people's needs.
