Adjust the height of the locating piece up and down, and install a measuring piece on the digital caliper; the bottom ends of the locating piece and the measuring piece are semi-conical, and the planes of the two semi-conical shapes are relatively arranged; during measurement, due to the positioning piece and the measuring piece The bottom of the measuring piece is semi-conical, and it cannot be guaranteed that the axis of the semi-cone coincides with the axis of the measuring hole. It is easy to cause inaccurate measurement and affect the processing accuracy, and the sharp corner of the semi-cone is easy to hurt people. Therefore, We have developed a hole measuring caliper, which can accurately measure the distance between two holes, and can measure the length, which is safe to use.

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Accompanying drawing 1 is the front view of measuring hole distance caliper described in the utility model;

Accompanying drawing 2 is the enlarged right view of Fig. 1;

Accompanying drawing 3 is the partial enlarged view of place A in Fig. 1;

Among them: 1. Ruler body; 11. Fixed jaw; 12. Adjustable cone; 2. First sliding body; 21. Moving jaw; 3. Second sliding body; 31. Moving cone; 4. Elastic lock piece.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1-3 is the measuring hole distance caliper described in the utility model, comprises the ruler body 1 that cross-section is I shape and is marked with scale; The upper side of described ruler body one end is provided with fixed jaw 11, and the lower side is provided with An adjustable cone 12 that can slide up and down; the upper side of the ruler body is provided with a first sliding body 2 that can slide left and right, and the lower side is provided with a second sliding body 3 that can slide left and right. The first sliding body 2 and the second sliding body 3 are respectively provided with scales, and through the scales on the ruler body 1, the distance between the two holes and the length of the parts can be read quickly, and can be accurate to the wire; the first sliding body 2 The movable jaw 21 corresponding to the fixed jaw 11 is arranged on the top, and the length of the part is clamped by the fixed jaw 11 and the movable jaw 21; The movable cone 31, because the movable cone 31 is arranged in the middle part of the second sliding body 3, the stress of the second sliding body 3 is relatively uniform, and the sliding is relatively stable; the adjustable cone 12 and the movable cone 31 The cone head is downwards, and the adjustable cone 12 slides up to be as high as the movable cone 31. By placing the adjustable cone 12 and the movable cone 31 in the hole to be measured, the distance between the two holes is measured, and Through the sufficient contact between the cone surface and the hole, it can be ensured that the axis of the adjustable cone 12 or the movable cone 31 coincides with the axis of the measuring hole, which improves the measurement accuracy; the first sliding body 2 and the second sliding body 3 The outer ends are respectively provided with elastic locking blocks 4; the bottom of the elastic locking blocks 4 is flat and has a slope with the side of the ruler body 1, the slope is 5-10 degrees, and the elastic locking blocks 4 are pressed during the measurement. The first sliding body 2 or the second sliding body 3 is fixed on the ruler body 1 by friction force, which is convenient for reading.

When in use: when measuring holes of the same size, first place the adjustable cone 12 and the moving cone 31 in the hole to be measured so that the cone surface is fully in contact with the hole, and then move the adjustable cone 12 up to meet the moving cone Body 31 equal height, finally read the measured value.

When measuring holes of different sizes, first place the adjustable cone 12 and the moving cone 31 in the hole to be measured so that the cone surface is fully in contact with the hole, and then adjust the adjustable cone 12 up and down to make the ruler body 1 and the two holes measured parallel to the plane, and finally read the measured value.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The hole measuring distance caliper described in the utility model can accurately measure the distance between the two holes and the length of the parts by placing the adjustable cone and the moving cone in the hole to be measured and fully contacting the hole. Simple, easy to use and safe.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
