Description

Technical Field

[0001] The utility model belongs to the technical field of laser marking devices, in particular to a laser marking device for building construction. Background Art

[0002] The laser marking device uses laser to form a high-brightness fan-shaped surface. When the laser is projected onto an object, a high-brightness laser line is formed to provide marking guidance for the user. Due to the use of illumination, the tedious process of manual marking and marking is reduced, the production efficiency is improved, and the traces caused by manual marking are avoided. The principle is to emit a high-brightness laser line. After passing through the optical component, the laser line can be diffused into a uniform laser fan-shaped surface required by the user. When the fan-shaped surface is projected onto an object, a high-brightness laser line can be formed, which can be used for cutting and marking and other functions. However, the existing laser marking device has a rigid structure and cannot be flexibly adjusted, so it cannot adapt to operations and uses in various situations.

[0003] At the same time, the patent specification with announcement number CN 207180670 U discloses a focusable laser marker, including a shell, an imaging lens, a focusing lens, a laser diode, a driving circuit, a focusing lens seat and a laser fixing seat. The shell includes a front shell and a rear shell, and the front shell and the rear shell are both provided with a cavity. The focusing lens is arranged at one end of the focusing lens seat, and the laser diode is arranged at one end of the laser fixing seat. The imaging lens, the focusing lens seat and the laser fixing seat are arranged in sequence relative to the central axis of the shell, and the imaging lens and the focusing lens seat are arranged in the front shell cavity.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned adjustable-focus laser marking device has the following problems: although the utility model can adjust the focal length of the marking device, its angle, height, and overall structure cannot be adjusted, so that the marking device may not be usable when facing different situations, or the marking device may not be able to fully play its role. Its limitations are too high.

[0005] Therefore, a laser marking device for building construction is proposed to solve the above problems. Utility Model Content

[0025] Specifically, a laser lens 16 is fixedly provided on the outer side of the marking device body 15, and an adjustment component is rotatably provided on the outer side of the laser lens 16. The focal length of the laser emitted by the laser lens 16 can be adjusted by the adjustment component, thereby making the work more convenient.

[0026] Furthermore, a plurality of fixing plates 2 are fixedly arranged on the outer side of the fixing plate 1, and rotating buckles 11 are rotatably arranged on both sides of the top of the fixing plates 2, and the rotating buckles 11 are engaged with the mounting plate 12, and the rotating buckles 11 are used to fix the mounting plate 12 and the fixing plate 1, thereby ensuring the stability of the mounting plate 12 and the marking device body 15 on its top.

[0027] Furthermore, a groove 13 is provided on the top surface of the installation disk 12, and the groove 13 is located outside the rotating buckle 11. The groove 13 can be smoothly opened through the groove 13, so that the installation disk 12 can be removed for subsequent use.

[0028] It is worth noting that a knob 9 is threadedly connected to the outer side of the rotating shaft 8, and the knob 9 fits against the telescopic shaft 7. Turning the knob 9 can loosen the connection between the rotating shaft 8 and the telescopic shaft 7, thereby adjusting the length of the telescopic shaft 7, and the knob 9 plays a fixing role.

[0029] It is worth noting that a short shaft 17 is rotatably provided inside the mounting plate 12, and a sliding shaft 18 is slidably provided inside the short shaft 17.

[0032] Working principle and process:

[0033] Before using a laser marking device for construction, first, adjust the marking device structure according to the on-site use requirements. If there is a certain height requirement, turn the knob 9 to loosen the rotating shaft 8 and the telescopic shaft 7, and then adjust the length of the angle between the rotating shaft 8 and the telescopic shaft 7 to find a suitable working state. If the bottom surface is loose, the fixed foot 10 can be inserted into the soil for fixation, and then the threaded sleeve 6 is turned to loosen the connection between the fixed shaft 3 and the fixed sleeve 4, and then the height of the fixed disk 1 is adjusted. Here, the outer diameter of the thread of the threaded sleeve 6 is smaller than the inner diameter of the top thread of the fixed sleeve 4, so that the fixed shaft 3 and the fixed sleeve 4 can be locked, and the buffer groove 5 is used to buffer the conflict between the threads of the threaded sleeve 6 and the fixed sleeve 4. After all adjustments are completed, turn the adjusting sleeve 14 to adjust the tightness of the marking device body 15 and the mounting disk 12, and then turn the marking device. The device body 15 is connected to the laser lens 16 for angle adjustment to ensure the accuracy of the laser beam. If the height requirement of the work site is low, the connection between the rotating buckles 11 on both sides of the fixing plate 2 and the mounting plate 12 can be opened through the groove 13, and the mounting plate 12 and the marking device body 15 can be removed together, and then the short shaft 17 is taken out, and then the rotating sleeve 19 is rotated to adjust the angle of the sliding shaft 18, so as to level it to ensure the normal use of the fixed plate 1. After all adjustments are completed, the adjusting sleeve 14 is rotated to drive the marking device body 15 to rotate together, so as to adjust the angle of the laser lens 16 to ensure the accuracy of the laser beam. The utility model adjusts the height, angle, and overall structure of the marking device to adapt to different usage conditions, thereby ensuring the normal use of the marking device and the smooth completion of the work, reducing the limitations of the marking device, and improving work efficiency.
