Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and in particular to an automatic leveling adjustable height horizontal laser line laying device. Background Technology

[0002] A laser level is a common tool in construction and decoration, used to measure horizontal lines and check whether a surface is level. Currently, most laser levels can only measure horizontal lines at a certain height, or they can be fixed to an extended bracket or pole, and the height of the bracket or pole can be adjusted to measure horizontal lines at different heights. In order to ensure that the laser level is set horizontally, the operator needs to observe the position of the bubble in the bubble tube while rotating the corresponding adjustment knob, and finally make the bubble in the bubble tube centered between the two graduation lines to achieve leveling.

[0003] A search revealed patent CN102679965B, which discloses a height-adjustable crosshair laser level. The method involves roughly setting up a telescopic tripod to the desired height. Six leveling buttons are located between the fixed and movable bases. Using a universal level, rotating these buttons adjusts the distance between the fixed and movable bases, achieving levelness. Then, rotating the lifting adjustment knob moves the graduated lifting rod up and down, accurately adjusting the crosshair laser beam to the desired height. However, this manual leveling method requires repeated adjustments and introduces visual errors when observing the bubble position in the universal level, reducing accuracy. It also demands great patience and skill from the operator, especially on uneven surfaces where instrument stability is poor. The leveling process is time-consuming, laborious, and prone to errors, resulting in low overall measurement efficiency. Furthermore, this height adjustment method is cumbersome, reducing operator efficiency, and frequent adjustments to the lifting rod can damage it. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic leveling adjustable height laser leveling device that overcomes the shortcomings of existing laser levels, such as cumbersome operation, easy damage to the lifting rod, poor stability, low measurement accuracy, and low work efficiency. It achieves the goals of simple operation, reduced instrument damage, improved instrument stability, high measurement accuracy, and high work efficiency.

[0007] Furthermore, the self-standing pointer and the first pointer correspond to the scale of the first dial, with the bottommost scale of the first dial set to 0°, and each 1° mark being a scale mark.

[0008] Furthermore, the second dial is hollow inside, the second gear ring is located inside the second dial, and a third pointer is provided on the upper surface of the rotating disk. The third pointer corresponds to the scale of the second dial, and each 5° mark is used. The base of the third dial is a solid base, while the other parts are hollow inside. The second bearing is located below the first gear ring, and the fixed seat is equipped with a second pointer. The second pointer corresponds to the scale of the third dial. The third dial uses a scale mark of 1°.

[0015] The present invention adopts the above technical solution and has the following advantages compared with the prior art: When in use, open the tripod and adjust the laser device to a vertical state. The counterweight keeps the gravity rod in a vertical state under the action of gravity. When the self-plumbing pointer coincides with 0° on the first scale, it proves that the fixed seat is in the vertical direction. Then, lock the third locking device and the fifth locking device in sequence to achieve automatic leveling and reduce the leveling steps.

[0016] After leveling, rotating the fourth locking device drives the second gear, second gear ring, rotating disk, balance ring, gravity bar, fixed base, and laser device to rotate, allowing the laser device to perform a coarse horizontal angle adjustment and lock. Then, rotating the second locking device drives the first gear, first gear ring, fixed base, and laser device to rotate, allowing the laser device to perform a fine horizontal angle adjustment and lock. Finally, vertically rotating the laser device adjusts the vertical angle. Once in place, rotating the first locking device locks the laser device. The operation is simple and improves the operator's work efficiency. By setting a stabilizing bar, the stability of the instrument can be improved, while effectively reducing instrument damage and improving measurement accuracy. Attached Figure Description

[0031] Instructions for use: When in use, open the tripod 20 and adjust the laser device 1 to a vertical position. The counterweight 18 will keep the gravity rod 10 in a vertical position under the action of gravity. When the self-dipole pointer 4 coincides with 0° on the first scale 3, it proves that the fixed seat 2 is in the vertical direction. Then, lock the third locking device 12 and the fifth locking device 37 in sequence to achieve automatic leveling and reduce the leveling steps.

Finally, rotating the laser device 1 vertically adjusts the vertical angle. After it is in place, rotating the first locking device 6 locks the laser device 1.
