Description

Technical Field

[0001] This application relates to the field of laser measurement electronic equipment, and in particular to a laser marking device with angle line length marking function. Background Technology

[0002] Currently, accurate distance measurement is crucial for ensuring project quality in fields such as construction, interior design, and decoration. Traditional measuring tools, such as rulers and measuring tapes, while convenient and easy to use, fall short when dealing with complex spatial geometry, especially long distances and irregular shapes. With technological advancements, laser rangefinders have become widely used in these fields due to their efficiency and convenience. However, most existing laser rangefinders on the market can only measure distances in horizontal and vertical directions, lacking the ability to measure distances in inclined directions. This significantly limits their application potential in a wider range of scenarios.

[0003] Currently, laser rangefinders on the market mainly include several types such as handheld single-point rangefinders and multi-functional laser rangefinders. Handheld single-point rangefinders calculate the straight-line distance between the target object and the instrument by emitting a single laser beam and receiving the reflected signal, suitable for simple two-point distance measurements. Multi-functional laser rangefinders add angle measurement functionality, using a built-in angle sensor to assist in calculating distance values ​​in different directions; however, they still struggle to meet the need for precise measurement of light path length at tilt angles in specific situations. Furthermore, these instruments are typically large, complex to operate, inconvenient to carry, and relatively expensive, hindering widespread adoption.

[0004] While existing technologies can largely meet the distance measurement needs of daily life, some significant limitations and shortcomings remain. Firstly, the measurement range is limited, especially when measuring distances in inclined directions. Secondly, accuracy is not high, particularly in outdoor environments or under poor lighting conditions, where the accuracy of laser rangefinders is easily affected. Finally, these devices are too simplistic in function and cannot adapt well to diverse working environments, often requiring the use of multiple different measuring tools to complete tasks, causing considerable inconvenience to users.

[0005] In order to simultaneously measure horizontal beams and beams tilted at different angles, this application provides a laser marking device with angle line length marking function.

[0006] The laser marking device with angle line length marking function provided in this application adopts the following technical solution:

[0007] A laser marking device with angle line length marking function includes a horizontal rangefinder group and a vertical rangefinder group. The bottom of the horizontal rangefinder group is hinged to a positioning rotating disk for rotating the horizontal and vertical rangefinder groups. The bottom of the positioning rotating disk is fixed to a telescopic rod for adjusting the height of the positioning rotating disk. The other end of the telescopic rod is fixed to a base. The middle part of the horizontal rangefinder group is hinged at the center of the positioning rotating disk. The vertical rangefinder group is located on the side of the horizontal rangefinder group away from the positioning rotating disk. The middle part of the vertical rangefinder group passes through the horizontal rangefinder group and is hinged at the center of the positioning rotating disk.

[0011] Optionally, the vertical distance measuring instrument group includes a first vertical distance measuring instrument for length measurement, a second vertical distance measuring instrument, and a vertical sliding group for adjusting the horizontal distance between the first vertical distance measuring instrument and the second vertical distance measuring instrument.

[0018] By adopting the above technical solution, the slide groove is used to embed the first horizontal rangefinder and the second horizontal rangefinder, so that the first horizontal rangefinder slides along the slide groove, and the second horizontal rangefinder slides along the slide groove, thus preventing the first horizontal rangefinder and the second horizontal rangefinder from rotating along the screw axis.

[0022] By adopting the above technical solution, the one-dimensional laser rangefinder can accurately measure distances with a small error range.

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a laser marking device with angle line length marking function. (Refer to...) Figure 1 The laser marking device with angle line length marking function includes a horizontal rangefinder group 1, a vertical rangefinder group 2 hinged to one side of the horizontal rangefinder group 1, and a positioning rotating disk 3 hinged to the other side of the horizontal rangefinder group 1. The positioning rotating disk 3 is disc-shaped, and a telescopic rod 4 for height adjustment of the positioning rotating disk 3 is fixed to the side of the positioning rotating disk 3 away from the horizontal rangefinder group 1. A base 5 is fixed to the bottom of the telescopic rod 4. The horizontal rangefinder group 1, which rotates around the positioning rotating disk 3, is aligned with the horizontal laser line to be measured to realize the length measurement. The vertical rangefinder group 2, which rotates around the positioning rotating disk 3, is used to realize the length measurement of the inclined laser line at a specified angle to the horizontal laser line, thereby realizing the simultaneous completion of the measurement data of the horizontal laser line and the inclined laser line without changing the equipment.

[0032] Reference Figure 2 The horizontal rangefinder group 1 includes a first horizontal rangefinder 11, a second horizontal rangefinder 12, and a horizontal sliding group 13. The first horizontal rangefinder 11 measures the length of the horizontal laser line to be measured located to the left of the origin, and the second horizontal rangefinder 12 measures the length of the horizontal laser line to be measured located to the right of the origin. The first horizontal rangefinder 11 is fixedly connected to the left side of the horizontal sliding group 13, and the first horizontal rangefinder 11 is fixedly connected to the right side of the horizontal sliding group 13. The horizontal sliding group 13 can control the first horizontal rangefinder 11 and the second horizontal rangefinder 12 to slide towards or away from each other, thereby expanding the length measurement range. The maximum value of the expanded measurement range is the sum of the sliding distances of the first horizontal rangefinder 11 and the second horizontal rangefinder 12.

[0033] Reference Figure 2 The horizontal sliding assembly 13 includes a horizontal sliding plate 131, the middle of which is hinged to the center of the positioning rotary disk 3. A first horizontal rangefinder 11 is provided on the left side of the horizontal sliding plate 131, and a second horizontal rangefinder 12 is provided on the right side of the horizontal sliding plate 131. An equidistant adjustment assembly 132 is provided between the first horizontal rangefinder 11 and the second horizontal rangefinder 12 for adjusting the first horizontal rangefinder 11 and the second horizontal rangefinder 12. The equidistant adjustment assembly 132 is used to realize the equidistant sliding adjustment of the first horizontal rangefinder 11 and the second horizontal rangefinder 12 relative to the middle of the horizontal sliding plate 131, thereby expanding the measurement range of length.

[0034] Reference Figure 2The equidistant adjustment group 132 includes two fixed bases 1321. The fixed base 1321 on the left is bolted to the first horizontal rangefinder 11, and the fixed base 1321 on the right is bolted to the second horizontal rangefinder 12. A screw 1322 is connected through the bottom of the two fixed bases 1321. The threaded section of the screw 1322 includes two threaded sections with opposite directions of rotation. The threaded section on the left is threaded to the fixed base 1321 on the left, and the threaded section on the right is threaded to the fixed base 1321 on the right. The two opposite threaded sections control the corresponding two fixed bases 1321 to slide equidistantly towards or away from each other.

[0035] Reference Figure 2 A groove 133 is provided in the middle of the horizontal sliding plate 131. The first horizontal rangefinder 11 is slidably connected to the left half of the groove 133, and the second horizontal rangefinder 12 is slidably connected to the right half of the groove 133. The groove 133 is used to restrict the rotation of the first horizontal rangefinder 11 and the second horizontal rangefinder 12 along the screw 1322.

[0036] Reference Figure 2 The vertical sliding assembly 23 includes two vertical fixed bases 231. The top vertical fixed base 231 is bolted to the first vertical rangefinder 21, and the bottom vertical fixed base 231 is bolted to the second vertical rangefinder 22. A vertical adjusting screw 232 is provided between the two vertical fixed bases 231. The threaded section of the upper half of the vertical adjusting screw 232 is threaded to the upper vertical fixed base 231, and the threaded section of the lower half of the vertical adjusting screw 232 is threaded to the lower vertical fixed base 231. When the vertical adjusting screw 232 is rotated and adjusted, the first vertical rangefinder 21 and the second vertical rangefinder 22 slide towards each other / away from each other, thereby realizing the distance adjustment between the first vertical rangefinder 21 and the second vertical rangefinder 22 for measuring the length of different inclined laser lines.

[0037] Reference Figure 2 The first horizontal rangefinder 11, the second horizontal rangefinder 12, the first vertical rangefinder 21, and the second vertical rangefinder 22 are one-dimensional laser rangefinders. The first horizontal rangefinder 11 and the second horizontal rangefinder 12 measure the length of horizontal laser lines of different lengths, and the first vertical rangefinder 21 and the second vertical rangefinder 22 measure the length of inclined laser lines of different lengths.

[0038] The implementation principle of a laser marking device with angle line length marking function in this application embodiment is as follows: The operator places the base 5 on the platform and uses the telescopic rod 4 to adjust the position of the center of the positioning rotating disk 3. According to the angle of the horizontal laser line, the horizontal sliding plate 131 is rotated clockwise / counterclockwise so that the straight line formed by the first horizontal rangefinder 11 and the second horizontal rangefinder 12 coincides with the horizontal laser line. The screw 1322 is rotated to make the first horizontal rangefinder 11 and the second horizontal rangefinder 12 at both ends of the screw 1322 move towards each other at equal distances / away from each other, thereby completing the measurement of the length of the horizontal laser at different lengths. After the measurement is completed, the vertical rangefinder group 2 is adjusted so that the straight line between the first vertical rangefinder 21 and the second vertical rangefinder 22 coincides with the inclined laser line. After the coincidence, the vertical adjustment screw 232 is rotated to adjust the distance between the first vertical rangefinder 21 and the second vertical rangefinder 22, thereby measuring the length of the inclined laser line at different lengths.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
