Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a device for measuring height difference and longitudinal spacing. Background Art

[0002] Vernier caliper is a measuring tool for measuring length, inner and outer diameter, and depth. It consists of a main scale and a sliding vernier attached to the main scale. It has the characteristics of simple structure, easy use, medium accuracy, and a large measuring range. It can be used to measure the inner diameter, outer diameter, length, width, thickness, depth, and hole spacing of parts. It has a wide range of applications and is a universal measuring tool.

[0003] Generally speaking, vernier calipers are used to measure relatively regular objects. However, when there is a height difference between the positions (generally referring to the length) of the objects to be measured, the length of the two measuring needles of the vernier caliper is limited. When there is an obstruction between the two measured points, the measurement is difficult to carry out; and when there is a height difference, the accuracy of the longitudinal spacing cannot be guaranteed. Therefore, a device for measuring the height difference and the longitudinal spacing is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a device for measuring height difference and longitudinal spacing, which can simultaneously measure the longitudinal spacing and height difference between two measuring points, reduce the influence of the measured object itself on the measurement, and the set level bubble can further ensure the accuracy of the measurement.

[0005] The technical solution to achieve the purpose of the utility model is: a device for measuring height difference and longitudinal spacing, including a vernier main scale, a vernier scale is slidably connected to the surface of the vernier main scale, a level bubble is provided on one side of the vernier main scale and the vernier scale, an extension block is fixedly connected to the other side of the vernier scale, the extension block is the same length as the bending part of the main scale, and a second main scale is provided on the main scale and the extension block.

[0006] In some embodiments, an empty slot is formed on the extension block, the second main scale is located in the empty slot, and the second main scale is fixed in the empty slot by bolts.

[0007] In some embodiments, a digital display vernier is slidably connected to the surface of the second main scale, and a probe is fixedly connected to one side of the digital display vernier.

[0008] Compared with the prior art, the utility model has the following significant advantages:

[0009] Firstly, the utility model combines several main rulers and moves the probes of two second main rulers during measurement, so that the measurement process is no longer hindered by the height difference between the objects, and the longitudinal distance and height difference between the two measurement points can be obtained at the same time. Meanwhile, several level bubbles can also ensure the accuracy of the measurement results.

[0010] Second: The utility model, by adding two second main scales on the vernier scale and the vernier main scale, and level bubbles arranged on the vernier scale and the vernier main scale, when there is an obstruction between the two measured points, the probes attached to the two second main scales are respectively arranged on the two measured points, and the level bubble is used as a reference. The position of the level bubble is observed to determine whether the positions of the two probes are balanced at this time, and then the readings of the two digital display vernier scales are respectively obtained. At this time, the difference between the readings of the two digital display vernier scales is the height difference between the two measured points.

[0011] The invention solves the problem of inaccurate and inconvenient measurement of the existing vernier caliper when measuring objects with objects blocking or with height differences between two measured points. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides a device for measuring height difference and longitudinal spacing through improvement. The technical solution of the utility model is:

[0020] like Figure 1 As shown, a device for measuring height difference and longitudinal spacing includes a vernier main scale 1, a vernier scale 2 is slidably connected to the surface of the vernier main scale 1, scales are set on both the vernier main scale 1 and the vernier scale 2, and level bubbles 3 are set on one side of the vernier main scale 1 and the vernier scale 2. There are three level bubbles 3 in total, two of which are set on the vernier main scale 1, and the two level bubbles 3 are respectively set at the head and tail ends of the vernier main scale 1, and the remaining level bubble 3 is set on the vernier scale 2. An extension block 4 is fixedly connected to the other side of the vernier scale 2. To ensure that the starting positions of the two second main scales 5 are the same and the measurement results are accurate, the extension block 4 is the same length as the bending part of the main scale, and the second main scale 5 is set on the main scale and the extension block 4.

[0021] like Figure 2 As shown, in one embodiment, an empty slot is provided on the extension block 4, and the second main scale 5 is located in the empty slot. The second main scale 5 is fixed in the empty slot by bolts. The same method is also used to fix another second main scale 5 on the same vernier main scale 1, ensuring that there is no error in the relative positions of the two second main scales 5, thereby ensuring the accuracy of measurement.

[0022] like Figure 3 As shown, in one embodiment, a digital display vernier 6 is slidably connected to the surface of the second main scale 5, a display screen is provided on the digital display vernier 6, a probe 7 is fixedly connected to one side of the digital display vernier 6, and a groove for accommodating the probe 7 is provided on the second main scale 5.

[0023] The specific working method is: when the device for measuring height difference and longitudinal spacing is used, the user first determines the two points to be measured, that is, the two points contacted by the two probes 7, first moves the vernier scale 2, and when the vernier scale 2 drives one of the second main scales 5 to reach the measuring point position, then adjusts the digital display vernier scales 6 on the two second main scales 5. After completing the above adjustment, while ensuring that the positions of several level bubbles 3 are centered, the scale reading on the main scale is the longitudinal spacing of the measured parts, and the difference between the readings of the two digital display vernier scales 6 is the measured height difference.

[0024] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
