Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

Embodiment of the utility model multifunctional vernier caliper: as shown in Figure 1, the multifunctional vernier caliper comprises a main ruler 1 and a vernier 3, the upper left end of the main ruler 1 is provided with a first measuring internal jaw 11, and the lower left end is provided with a second A measuring outer claw 12, a second measuring inner claw 31 used in conjunction with the first measuring inner claw 11 is provided on the upper left end of the cursor, and a second measuring outer claw 31 used in conjunction with the first measuring outer claw 12 is provided on the lower side of the left end of the cursor 32. The front side of the main scale 1 is provided with a main scale line 13, and the vernier 3 is provided with a vernier scale line 33 used in conjunction with the main scale line 13. The right end of main ruler 1 is also provided with depth ruler 14. The structure introduced in this part is similar to the existing vernier caliper. Both the first measuring inner claw and the second measuring inner claw are provided with avoidance grooves to reduce the contact area between the inner claws and the object to be measured, so as to improve the measurement accuracy.

A crosshair laser 34 is arranged on the cursor, and the crosshair laser 34 is fixed on the cursor 3 by screws. There is a card slot on the lower side of the frame of the crosshair laser, and the card slot is locked on the vernier, and then fixed by screws. The horizontal line of the reticle that the reticle laser 34 sends is parallel to the main ruler 1, and the vertical line is perpendicular to the main ruler 1. The non-contact measurement between the caliper and the object to be measured can be realized by using the crosshair laser. The specific principle is as follows: when in use, place the main ruler 1 at a suitable position, place it horizontally, keep the main ruler still, and move the cursor 3, Make the vertical line of the cross laser line emitted by the laser tangent to the left end of the object to be measured, align it, record the reading of the caliper at this time, and then move the cursor so that the vertical line of the cross line emitted by the laser is tangent to the right end of the object to be measured , align, and record the reading at this time. The subtraction of the two readings before and after is the length of the object to be measured.

Furthermore, the first measuring outer claw is provided with a horizontal air bubble 2, which can judge the state of the caliper during use, not only can be used as a level, but also can improve the measurement accuracy of the caliper.
