The measurement error is large, time-consuming and laborious, and is only suitable for general rough verticality measurement.
[0003] However, the existing high-precision digital display verticality measuring instruments have a complex structure, resulting in high equipment investment costs.

[0019] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] See also Figure 1 and Figure 2The utility model provides a simple high-precision verticality measuring instrument, which includes a ruler body 1 as a vertical reference, a ruler frame 3 installed on the ruler body 1 and capable of sliding relative to its extension direction, and a detection gauge 4 fixedly installed on the ruler frame 3 (specifically in this embodiment, the detection gauge 4 can be a traditional lever gauge, and of course a micrometer or other gauges can also be used). In this embodiment, the ruler frame 3 is a sleeve-shaped structure, which is installed on the ruler body 1 in a sleeve-shaped manner; the detection gauge 4 is installed on the ruler frame 3 through a bracket 01, and its working end contacts the surface to be measured, and the length of the ruler body 1 is set according to the length to be measured of the surface to be measured. Under normal circumstances, the length of the ruler body 1 should be greater than the length to be measured of the surface to be measured.
[0021] The end of the ruler body 1 is installed with a base 00 for fixing and supporting it. The base 00 can maintain the vertical state of the ruler body 1 and keep its state stable. The base 00 is provided with an installation groove for inserting the ruler body 1. During installation, the end of the ruler body 1 can be inserted into the installation groove.
[0022] During the inspection, the base 00 is placed on the platform so that the ruler body 1 is in a vertical position (to achieve calibration). The ruler frame 3 is held and moved along the ruler body 1. The moving ruler frame 3 will synchronously drive the output end of the detection table 4 to move in contact with the surface to be measured. During the movement, the distance deviation between the ruler body 1 and the surface to be measured is detected by the detection table 4 to indirectly reflect the verticality of the surface to be measured.
[0023] See also Figure 2 and Figure 4 Preferably, in order to prevent the ruler body 1 from falling out of the installation groove due to the movement of the ruler body 1 (the friction force during the movement of the ruler frame 3 may cause the ruler body 1 to move) during the measurement process, the utility model makes the following improvements: a positioning protrusion 11 is provided at the connecting end of the ruler body 1; a positioning piece 5 that cooperates with the positioning protrusion 11 is fixedly connected to the base 00. Specifically in this embodiment, the positioning piece 5 is a fixed cover, which is sleeved on the outside of the ruler body 1 and fixed to the base 00 by screws; the positioning piece 5 presses the positioning protrusion 11 to axially position the ruler body 1.
[0024] See also Figure 2 and Figure 3 In addition, after using the device, the user will lose control of the ruler frame 3, causing it to fall naturally, which may easily cause it to collide with the base 00, resulting in damage to the ruler frame 3, further affecting the accuracy of the detection; a buffer layer 6 is provided on the base 00 near the ruler body 1 to buffer its fall, and the falling ruler frame 3 can be buffered by the buffer layer 6. Specifically in this embodiment, the buffer layer 6 is an annular rubber ring.
[0025] Furthermore, since during the installation process, the ruler frame 3 and the ruler body 1 are installed with a gap (after installation, there is a gap between the inner wall of the ruler frame 3 and the outer wall of the ruler body 1), during the falling process, the ruler frame 3 does not have its bottom wall in uniform contact with the surface of the base 00, but under the gravity of the detection table 4, one side of the ruler frame 3 will preferentially contact the base 00, resulting in that during the collision, this part (the bottom wall of the ruler frame 3 close to the detection table 4) is subjected to a greater impact. In this regard, the above problem has not been solved. The present application makes the following improvements: the buffer layer 6 is provided with a protruding structure 31 at one end close to the detection table 4. The protruding structure 31 is also made of a buffering material, and the above (the bottom wall of the ruler frame 3 close to the detection table 4) is focused on buffering by the protruding structure 31. At the same time, in order to prevent the protruding structure 31 from affecting the detection of the detection table 4, a matching groove 311 that matches the protruding structure 31 is provided at the bottom of the ruler frame 3 to ensure that the bottom wall of the ruler frame 3 is in a horizontal state after falling.
[0026] In summary, the utility model provides a simple high-precision verticality measuring instrument, including a ruler body as a vertical reference, a ruler frame installed on the ruler body and capable of sliding relative to its extension direction, and a detection gauge fixedly installed on the ruler frame (specifically in this embodiment, the detection gauge can be a traditional lever gauge, and of course a micrometer or other gauges can also be used), wherein the ruler frame is a sleeve-shaped structure, which is installed on the ruler body in a sleeve-like manner; the detection gauge is installed on the ruler frame through a bracket, and its working end contacts the surface to be measured, and the length of the ruler body is set according to the length to be measured of the surface to be measured. Under normal circumstances, the length of the ruler body should be greater than the length to be measured of the surface to be measured. The utility model provides a verticality measurement structure with a relatively simple structure, which not only realizes measurement but also effectively solves the problem of collision between the ruler frame and the base during the release process.
[0027] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
