Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a stainless steel digital caliper with a protection structure, including a ruler body 1 and a digital display vernier 2. A positioning hole 3 is opened on one side of the measuring end at the bottom of the ruler body 1. A tightening bolt 4 is movably installed inside the positioning hole 3. A first U-shaped protective shell 5 is movably installed on the surface of the tightening bolt 4. Bushings 6 are fixedly installed at the bottoms of both sides of the first U-shaped protective shell 5. An assembly plate 7 is movably installed on the surface of the tightening bolt 4 and outside the first U-shaped protective shell 5. A second U-shaped protective shell 8 is fixedly installed outside the assembly plate 7.

[0024] Among them, through the mutual cooperation of the tightening bolt 4, the first U-shaped protective shell 5, the bushing 6, the assembly plate 7, and the second U-shaped protective shell 8, the function of protecting the measuring end of the digital caliper is realized. Thus, the safety performance of the digital caliper can be increased, and damage to the measuring end caused by accidental collision or dropping during the use of the digital caliper can be avoided, thereby ensuring that the digital caliper always maintains a high-precision measuring ability during use.

[0025] A tightening nut 9 is engaged and connected to the surface of the tightening bolt 4 and outside the second U-shaped protective shell 8. A flexible protective sleeve 10 is fixedly installed outside the digital display vernier 2.

[0026] Among them, through the tightening nut 9, it is convenient to adjust the sensitivity of the first U-shaped protective shell 5 in cooperation with the assembly plate 7, so that the user can adjust the placement position of the first U-shaped protective shell 5 according to different measurement requirements. Through the flexible protective sleeve 10, the function of protecting the digital display vernier 2 is realized. Thus, the impact on the internal electronic devices of the digital display vernier 2 caused by impact or vibration can be reduced, and further the service life of the digital display vernier 2 is extended.

[0027] One side of the bottom measuring end of the digital display vernier 2 is provided with a U-shaped through hole 11, and an elastic clamping block 12 is movably installed inside the U-shaped through hole 11.

[0028] Among them, the U-shaped through hole 11 facilitates the cooperation with the elastic clamping block 12 to realize the function of limiting the triangular U-shaped protective sleeve 13, so as to ensure that the triangular U-shaped protective sleeve 13 comprehensively protects the bottom measuring end of the digital display vernier 2 and prevent the triangular U-shaped protective sleeve 13 from deviating during use.

[0029] Both ends of the elastic clamping block 12 are threadedly connected with a triangular U-shaped protective sleeve 13, and a limiting cylinder 14 is fixedly installed on the outer side of the triangular U-shaped protective sleeve 13.

[0030] Among them, the triangular U-shaped protective sleeve 13 facilitates the protection of the bottom measuring end of the digital display vernier 2, avoiding damage to the bottom measuring end of the digital display vernier 2 caused by vibration during the placement of the digital caliper or accidental dropping during the process. The limiting cylinder 14 facilitates the limitation of the spring 15 and prevents the spring 15 from detaching from the inside of the triangular U-shaped protective sleeve 13 during use.

[0031] A spring 15 is fixedly installed inside the limiting cylinder 14, and an elastic pad 16 is fixedly installed at one end of the spring 15.

[0032] Among them, the spring 15 facilitates the use of its deformable characteristics to improve the protection performance of the triangular U-shaped protective sleeve 13, further reducing the damage of the impact force to the digital caliper. The elastic pad 16 facilitates increasing the contact area between the spring 15 and the measuring end, thereby reducing the wear of the spring 15 on the measuring end. At the same time, it can also cooperate with the spring 15 to degrade the impact force, further improving the protection performance of the digital caliper.

[0033] An elastic push block 17 is fixedly installed at the bottom of the flexible protective sleeve 10 and on the side far from the measuring end.

[0034] Among them, the elastic push block 17 facilitates reducing the wear of the vernier by the user during use, and can also provide protection for one end of the bottom of the vernier.

[0035] Both the second U-shaped protective shell 8 and the triangular U-shaped protective sleeve 13 are slightly lower than the contact surface of the measuring end.

[0036] Working principle and usage process of the present utility model: When the digital caliper accidentally drops due to impact, the first U-shaped protective shell 5 absorbs the impact force on the measuring end at the top of the ruler body 1, the second U-shaped protective shell 8 absorbs the impact force on the measuring end at the bottom of the ruler body 1, the triangular U-shaped protective sleeve 13 absorbs the impact force on the measuring end at the bottom of the vernier, the spring 15 cooperates with the elastic pad 16 to degrade the impact received by the triangular U-shaped protective sleeve 13, the flexible protective sleeve 10 absorbs the impact force on the digital vernier 2. When measuring the inner diameter with the top measuring end, the first U-shaped protective shell 5 rotates to the inside of the second U-shaped protective shell 8 by rotating the bushing 6 on the surface of the fastening bolt 4, and then the inner diameter can be measured. At this time, the center of gravity of the digital caliper is at the second U-shaped protective shell 8. If the caliper accidentally drops, the first U-shaped protective shell 5 cooperates with the second U-shaped protective shell 8 to absorb the impact force on the whole digital caliper. After use, rotate the bushing 6 on the surface of the fastening bolt 4 again to make the first U-shaped protective shell 5 rotate to the top measuring end of the ruler body 1, move the digital vernier 2 to close to the measuring end of the ruler body 1 through the ruler body 1. The triangular U-shaped protective sleeve 13 protects the measuring end at the bottom of the digital vernier 2 during its movement in real time. At this time, the first U-shaped protective shell 5 protects the measuring ends at the top of the ruler body 1 and the digital vernier 2 simultaneously, and then the digital caliper can be put back for reuse.
