Description

Technical Field

[0001] The present invention relates to the technical field of laser levels, and in particular to a laser level that is convenient for positioning. Background Art

[0002] In modern life, with the improvement of people's quality requirements for home life, laser measurement products are increasingly widely used in daily life. When construction workers perform tasks such as tile pasting on a construction wall, in order to ensure that the tiles can be neatly pasted on the construction wall, construction workers usually use a laser level. The laser level is vertically placed on the ground in front of the construction wall, and then the laser beam generated by the laser level is projected onto the wall, and a laser beam line projected on the wall is perpendicular to the ground. Construction workers can then neatly paste the tiles on the construction wall according to this straight laser beam on the wall. The laser level can generate multiple vertical and horizontal laser planes to determine the accuracy of the horizontal and plumb directions and is widely used in construction projects.

[0003] The laser level needs to be leveled before use. Currently, common laser levels cannot quickly position the laser level after leveling is completed, making the level prone to shaking during use and affecting the use effect. Therefore, we propose a laser level that is convenient for positioning to solve this problem. Summary of the Invention

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. In the present invention, for a laser level that is convenient for positioning, the laser level is placed at the usage position. Then, the pull ring is pulled downward to drive the pull rod and the plug rod to move downward, so that the plug rod disengages from the slot. Then, the threaded sleeve is rotated. The threaded sleeve drives the threaded column and the support plate to move up and down through the threaded transmission with the threaded column and under the guidance of the vertical rod. After the adjustment is completed, the pull ring is released, so that the plug rod moves upward under the action of the compression spring and inserts into the slot to lock the rotation of the threaded sleeve. The lengths of the three support legs are adjusted in sequence to adapt to the placement position.

[0026] 2. In the present invention, for a laser level that is convenient for positioning, by pressing the touch button, the horizontal laser emitter and the vertical laser emitter are controlled to start and emit laser rays. At the same time, the output end of the electric push rod is controlled to contract, thereby driving the locking disc to move downward. After the locking disc releases the locking of the counterweight plate, the counterweight plate rotates under the action of gravity, and the inner ring plate rotates within the middle ring plate and the middle ring plate rotates within the outer ring plate. The magnet is driven to move by the counterweight plate. The magnet drives the ball to move synchronously by magnetically attracting the ball. During the movement of the ball, the sliding seat is driven to move through the ball seat and the cross plate. When the sliding seat moves left and right, the circular shaft is driven to rotate through the engagement of the first rack and the second gear. When the sliding seat moves forward and backward, the cross beam and the mounting frame are driven to move forward and backward synchronously. Further, the vertical shaft is driven to rotate through the engagement of the first rack and the first gear. When the vertical shaft and the circular shaft rotate, the corresponding rotating box is driven to rotate. When the rotating box rotates, the two square plates move away from each other under the action of centrifugal force and drive the two control buttons to move away from each other.

[0027] 3. In the present invention, for a laser level that is convenient for positioning, as the mounting seat and the counterweight plate gradually return to the vertical state, the sliding seat stops moving, the circular shaft and the vertical shaft stop rotating, so that the rotating box stops rotating. The square plates reset under the elastic force of the connecting spring, causing the two control buttons to press against each other. When the four control buttons are simultaneously pressed, the output end of the electric push rod is extended, driving the locking disc to move upward. The rotation of the counterweight plate is restricted by the abutment of the locking disc against the bottom of the counterweight plate, thereby avoiding shaking during use.

[0028] 4. In the present invention, for the laser level that is convenient for positioning, by pulling down the sliding ring to drive the two clamping plates out of the clamping grooves, and then rotating the rotating ring to drive the baffle to move in a circular motion, so that the baffle is separated from the arc-shaped plate, thereby releasing the fixation of the transparent cover, and then the transparent cover can be moved upward for disassembly;

[0029] 5. In the present invention, for the laser level that is convenient for positioning, through the cooperation of the linkage mechanism and the locking mechanism provided, it can achieve automatic and rapid positioning work after the laser level is automatically leveled, ensuring the stability during subsequent use.

A rotating ring 204 is rotatably sleeved outside the circular track 203. Baffles 202 are fixedly installed on both sides of the top of the rotating ring 204, and the baffles 202 are in active abutment with the top of the corresponding arc-shaped plates 201;

[0064] In this embodiment, during use, the laser level is placed at the use position, and then the pull ring 406 is pulled downward to drive the pull rod 407 and the insertion rod 409 to move downward, so that the insertion rod 409 disengages from the insertion slot. Then the threaded sleeve is rotated. The threaded sleeve drives the threaded column 403 and the support disc 404 to move up and down through the threaded transmission with the threaded column 403 and under the guidance of the vertical rod 405. After the adjustment is completed, the pull ring 406 is released, so that the insertion rod 409 moves upward under the action of the compression spring 408 and inserts into the insertion slot to lock the rotation of the threaded sleeve. The lengths of the three support legs 4 are adjusted in sequence to adapt to the placement position;

[0065] Then the touch control button 603 is pressed to control the horizontal laser emitter 301 and the vertical laser emitter 302 to start and emit laser rays. At the same time, the output end of the electric push rod 602 is contracted, so as to drive the locking disc 6 to move downward. After the locking disc 6 releases the lock on the counterweight plate 5, the counterweight plate 5 rotates under the action of gravity, and the inner ring plate 303 rotates in the middle ring plate 304, and the middle ring plate 304 rotates in the outer ring plate 305, and the magnet 501 is driven to move by the counterweight plate 5. The magnet 501 drives the balls to move synchronously by magnetically attracting the balls.

When the sliding seat 10 moves left and right, the circular shaft 803 is driven to rotate through the meshing of the first rack 701 and the second gear 802. When the sliding seat 10 moves forward and backward, the cross beam 8 and the mounting frame are driven to move forward and backward synchronously. Furthermore, the vertical shaft 703 is driven to rotate through the meshing of the first rack 701 and the first gear 702. When the vertical shaft 703 and the circular shaft 803 rotate, the corresponding rotating boxes 9 are driven to rotate. When the rotating boxes 9 rotate, the two square plates 902 move away from each other under the action of centrifugal force and drive the two control buttons 901 to move away from each other;

[0066] As the mounting seat 3 and the counterweight plate 5 gradually return to the vertical state, the sliding seat 10 stops moving, the circular shaft 803 and the vertical shaft 703 stop rotating, so that the rotating boxes 9 stop rotating. The square plates 902 are reset under the elastic force of the connecting spring 903 so that the two control buttons 901 are pressed against each other. When the four control buttons 901 are simultaneously pressed, the output end of the electric push rod 602 extends, driving the locking disc 6 to move upward, and restricting its rotation through the abutment between the locking disc 6 and the bottom of the counterweight plate 5, thereby avoiding shaking during use;

[0067] Moreover, by pulling the sliding ring 208 downward, the two clamping plates 205 can be driven to disengage from the clamping grooves, and then by rotating the rotating ring 204, the baffle plate 202 can be driven to perform a circular motion, so that the baffle plate 202 is disengaged from the arc-shaped plate 201, thereby releasing the fixation of the transparent cover 2, and then the transparent cover 2 can be moved upward for disassembly.
