Description

Technical Field

[0001] This utility model relates to the technical field of steel ruler calibration table, specifically a steel ruler calibration table that is easy to position. Background Technology

[0002] The current method for calibrating laser rangefinders is to use a standard steel tape measure as the standard on a calibration platform. During the test, the laser rangefinder is fixed at the zero point of the standard steel tape measure. Standard reflectors are erected at different distances directly in front of the laser rangefinder. The instrument display value is read and manually recorded. The error at each test point is calculated. According to the calibration procedure, the data is processed to obtain the error values. Then, the error value with the largest absolute value error is taken as the calibration result to see if it is within the error range.

[0003] However, conventional steel ruler calibration stands are inconvenient for positioning and for adjusting the angle and height of the laser rangefinder. They are also not easy to adjust the overall height. Therefore, we propose a steel ruler calibration stand that is easy to position in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel ruler calibration table for easy positioning, comprising: a support table, a mounting plate bolted to the upper left end of the support table to provide load-bearing support, and a connecting seat placed on the upper side of the support table;

[0006] Also includes:

[0007] The mounting plate is provided with an adjustment structure and a lifting structure on its upper and lower sides, respectively. The adjustment structure includes an adjustment rod, a first connecting block, a limiting rod and a bearing plate, and the lifting structure includes a connecting column, a second connecting block, a second threaded rod and a sleeve.

[0008] The left longitudinal section of the connecting seat has an "L" shape, and the upper rear end of the connecting seat is integrally connected to a first limiting plate. The front middle end of the connecting seat has a connecting port, and an adjustment plate is slidably connected inside the connecting port.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7This utility model provides a technical solution: a steel ruler calibration platform for easy positioning, including a support platform 1, a mounting plate 2, an adjusting rod 3, a first connecting block 4, a limiting rod 5, a support plate 6, a connecting seat 7, a first limiting plate 8, a connecting port 9, an adjusting plate 10, a second limiting plate 11, a first threaded rod 12, a connecting column 13, a second connecting block 14, a second threaded rod 15, a sleeve 16, a mounting component 17, an adjusting seat 18, a distance measuring plate 19, and a standard ruler 20.

[0032] Example 1: Since existing methods exist, this example uses the following technical solution, such as... Figure 1 , Figure 2 and Figure 3 Since the connecting port 9 has an adjusting plate 10 that is slidably connected inside, and the first threaded rod 12 is threadedly connected to the upper front end of the connecting seat 7, and the second limiting plate 11 has a sliding structure at the upper end of the connecting seat 7 through the adjusting plate 10 and the first threaded rod 12, the laser rangefinder is placed at the upper end of the connecting seat 7, so that the rear end of the laser rangefinder abuts against the front end of the first limiting plate 8. The first threaded rod 12 is rotated so that it rotates at the front end of the second limiting plate 11, so that the first threaded rod 12 moves backward at the front end of the connecting seat 7, while the adjusting plate 10 slides backward inside the connecting port 9, so that the adjusting plate 10 drives the second limiting plate 11 to move backward at the upper end of the connecting seat 7 until the rear end of the second limiting plate 11 abuts against the front end of the laser rangefinder. The position of the laser rangefinder is limited by the first limiting plate 8 and the second limiting plate 11, so as to facilitate positioning.

[0033] Example 2: Since existing methods exist, this example uses the following technical solution, such as... Figure 1 and Figure 7 Since the lifting structure includes a connecting column 13, a second connecting block 14, a second threaded rod 15, and a sleeve 16, the bottom end of the support platform 1 is fixedly connected to the connecting column 13 at equal intervals, the lower end of the connecting column 13 is rotatably connected to the second connecting block 14, and the second threaded rod 15 is threadedly connected to the inside of the sleeve 16. The support platform 1 slides up and down on the upper side of the sleeve 16 through the second connecting block 14 and the second threaded rod 15. Therefore, by rotating the second connecting block 14 to make it rotate at the lower end of the connecting column 13, the second threaded rod 15 moves up and down inside the sleeve 16, adjusting the distance between the connecting column 13 and the sleeve 16, thereby easily adjusting the overall height.

[0034] Example 3: Since existing methods exist, this example uses the following technical solution, such as... Figure 1 , Figure 4 , Figure 5 and Figure 6The adjustment structure includes an adjustment rod 3, a first connecting block 4, a limiting rod 5, and a bearing plate 6. The left and right ends of the mounting plate 2 are symmetrically connected with adjustment rods 3 by threads. The outer surface of the adjustment rod 3 has a threaded structure. The limiting rod 5 is connected through the inner part of the outer end of the bearing plate 6. The bearing plate 6 is in a flipping structure on the upper side of the mounting plate 2 through the adjustment rod 3 and the limiting rod 5. Therefore, pushing the adjustment seat 18 allows it to move on the bearing platform 1, adjusting the distance between the ranging plate 19 and the laser rangefinder. When the height of the laser rangefinder needs to be adjusted, all the first connecting blocks 4 are rotated to make the adjustment rod 3 rise and fall on the mounting plate 2. When the adjustment rod 3 rises and falls, the distance between the bearing plate 6 and the mounting plate 2 is stopped. When the angle of the laser rangefinder needs to be adjusted, the two first connecting blocks 4 on the left are rotated to make the adjustment rod 3 rise. The adjustment rod 3 makes the first connecting block 4 rise, so that the first connecting block 4 makes the right end of the bearing plate 6 rise, so that the bearing plate 6 is in an inclined state, which facilitates the adjustment of the angle and height of the laser rangefinder. All the electrical components mentioned above are existing technologies and will not be described in detail here.
