Description

Technical Field

[0001] This utility model relates to the technical field of laser leveling, and in particular to a laser leveling device. Background Technology

[0002] In the construction industry, the flatness of the original ground, walls, and road surfaces must be assessed before decorating houses and paving roads. Professional methods must be used to ensure that the flatness meets certain standards; otherwise, warping, hollowing, and detachment of the paved surfaces may occur. After the construction work on the ground, walls, and roads is completed, their flatness must be inspected and accepted.

[0003] Laser leveling technology uses the principle of laser detection to measure whether a plane is uneven. In construction, lasers are commonly used to measure whether walls, floors, etc. are flat. It is widely used in construction, decoration and other fields. Traditional laser leveling devices do not have the function of adjusting the angle. They generally only have a single horizontal or vertical laser, which cannot adapt to different usage scenarios and brings inconvenience to the leveling of different building areas. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a laser leveling device that solves the problems of existing technologies where the angle cannot be adjusted and the single laser irradiation angle cannot adapt to different usage scenarios, thus causing inconvenience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A laser leveling device includes a support frame, an adjustable gimbal, and a laser leveling device;

[0007] The adjustable pan-tilt unit includes an adjustment box, an adjustment knob, a lifting column, a mounting platform, and a omnidirectional ball.

[0008] The lifting column is slidably disposed vertically within the adjusting box, and the omnidirectional ball is movably disposed above the lifting column.

[0009] The adjustment knob is located on the outer side of the adjustment box. The drive end of the adjustment knob is inserted into the adjustment box and connected to the lifting column for driving the lifting column to move up and down, thereby clamping the universal ball through the lifting column.

[0010] The mounting platform is positioned above the adjustment box, and a connecting column is provided on the bottom surface of the mounting platform. The connecting column is inserted into the adjustment box and fixedly connected to the universal ball.

[0011] The adjustment box is located at the top of the support frame, and the laser level is located on the mounting platform.

[0012] Preferably, the adjustment knob is connected to a drive shaft, the drive shaft is provided with drive teeth, and the side wall of the lifting column is provided with a lifting rack. The drive teeth are meshed with the lifting rack. The lifting column drives the drive shaft to rotate by rotating the adjustment knob, thereby performing lifting and lowering movements through the transmission between the drive teeth and the lifting rack.

[0013] Preferably, it also includes a locking nut, the drive shaft passes through the other side of the adjustment box, and the other end of the drive shaft is provided with a locking thread, and the locking nut is installed in conjunction with the locking thread.

[0014] Preferably, the top of the lifting column is provided with a lower elastic block, an upper elastic ring is provided between the universal ball and the top surface of the adjustment box, the universal ball is located between the upper elastic ring and the lower elastic block, and an arc groove is provided in the middle of the lower elastic block.

[0015] Preferably, the top and bottom of the lifting column are respectively provided with guide platforms, the outer wall of the guide platform is in contact with the inner wall of the adjustment box, and a compression spring is also provided between the guide platform at the top of the lifting column and the universal ball.

[0016] Preferably, an elastic rubber ring is also provided between the adjustment knob and the adjustment box.

[0017] Preferably, the bottom of the mounting platform is provided with an operating handle.

[0018] Preferably, the support frame includes a support column, an operating ring, a locking element, three linkage rods, and three support feet;

[0019] The operating ring is sleeved on the outer periphery of the support column and is slidably connected to the support column. The three support legs are arranged circumferentially at the bottom end of the support column, and one end of each support leg is hinged to the support column.

[0020] One end of each of the three linkage rods is hinged to the operating ring, and the other end is hinged to the middle of the support leg.

[0021] The locking element is disposed on the operating ring, and the locking element is used to lock with the support column to lock the operating ring.

[0022] Preferably, the top surface of the operating ring is circumferentially arranged with a plurality of clamping plates, the support column is slidably disposed on the inner sidewall of the clamping plates, the outer wall of the clamping plates is provided with threads, the thickness of the clamping plates gradually increases from top to bottom, the locking member is sleeved on the outer periphery of the clamping plates, and the locking member is threadedly connected to the clamping plates.

[0023] One of the above technical solutions has the following advantages or beneficial effects:

[0024] A laser leveling device, when in use, after placing the support frame on the ground, allows adjustment of the gimbal to change the illumination angle of the laser leveler. Adjusting a knob drives the lifting column to move up and down, moving it closer to or further away from the omnidirectional ball. When closer, the lifting column and the inner wall of the adjustment box compress and lock the omnidirectional ball, preventing it from rotating and fixing the current angle of the laser leveler. When the angle needs to be changed, adjusting the knob moves the lifting column away from the omnidirectional ball, freeing it from compression and allowing it to rotate. Rotating the mounting platform then adjusts the angle of the laser leveler, allowing for pitch, tilt, and other laser illumination methods to adapt to different usage scenarios and leveling operations.

[0034] The following is combined Figures 1 to 4 A laser leveling device according to an embodiment of the present invention includes a support stand 1, an adjustment gimbal 2, and a laser leveling device 3;

[0035] The adjustable gimbal 2 includes an adjustment box 21, an adjustment knob 22, a lifting column 23, a mounting platform 24, and a universal ball 25;

[0036] The lifting column 23 is slidably disposed within the adjusting box 21 in a vertical direction, and the omnidirectional ball 25 is movably disposed above the lifting column 23.

[0037] The adjustment knob 22 is located on the outer side of the adjustment box 21. The driving end of the adjustment knob 22 is inserted into the adjustment box 21 and is connected to the lifting column 23 for transmission. It is used to drive the lifting column 23 to move up and down, thereby clamping the universal ball 25 through the lifting column 23.

[0038] The mounting platform 24 is positioned above the adjustment box 21. A connecting post 26 is provided on the bottom surface of the mounting platform 24. The connecting post 26 is inserted into the adjustment box 21 and fixedly connected to the universal ball 25.

[0039] The adjustment box 21 is located at the top of the support bracket 1, and the laser leveling device 3 is located on the mounting platform 24.

[0040] Specifically, laser leveling technology uses laser detection to measure the unevenness of a surface. In construction, lasers are commonly used to measure the flatness of walls, floors, etc., and are widely applied in construction and decoration. Traditional laser leveling devices lack angle adjustment capabilities and generally only offer a single horizontal or vertical laser beam, making them unsuitable for different usage scenarios and causing inconvenience for leveling in various building areas. In this embodiment, after placing the support stand 1 on the ground, the illumination angle of the laser leveling device 3 can be changed by adjusting the pan-tilt head 2, thus adapting to different usage scenarios. Specifically, adjusting the knob 22 drives the lifting column 23. During the lifting and lowering movement, the lifting column 23 moves closer to or further away from the universal ball 25. When it moves closer to the universal ball 25, the inner walls of the lifting column 23 and the adjusting box 21 will press and lock the universal ball 25, preventing it from rotating and thus fixing the current angle of the laser leveling device 3. When it is necessary to change the angle of the laser leveling device 3, the lifting column 23 is moved away from the universal ball 25 by adjusting the knob 22. The universal ball 25 is no longer pressed and can rotate. At this time, rotating the mounting platform 24 can adjust the angle of the laser leveling device 3, allowing it to be illuminated by the laser in various ways such as pitching or tilting, thus adapting to leveling operations in different application scenarios.

[0041] Furthermore, the adjustment knob 22 is connected to a drive shaft 221, the drive shaft 221 is provided with drive teeth 222, and the side wall of the lifting column 23 is provided with a lifting rack 231. The drive teeth 222 are meshed with the lifting rack 231. The lifting column 23 drives the drive shaft 221 to rotate by rotating the adjustment knob 22, thereby performing lifting and lowering movements through the transmission between the drive teeth 222 and the lifting rack 231.

[0042] Specifically, in this embodiment, when it is necessary to adjust the angle of the laser leveling device 3, the adjustment knob 22 is turned, and the drive shaft 221 rotates. Since the drive gear 222 is meshed with the lifting rack 231, the drive gear 222 of the drive shaft 221 will drive the lifting rack 231, thereby causing the lifting column 23 to move. The meshing transmission between the drive gear 222 and the lifting rack 231 is stable and reliable, and the structure is stable.

[0043] Furthermore, it also includes a locking nut 27, the drive shaft 221 passes through the other side of the adjustment box 21, the other end of the drive shaft 221 is provided with a locking thread, and the locking nut 27 is installed in conjunction with the locking thread.

[0044] Specifically, in this embodiment, the locking nut 27 is connected to one end of the drive shaft 221. Tightening the locking nut 27 will pull the adjusting knob 22 towards the adjusting box 21 through the drive shaft 221, thereby locking the adjusting knob 22 and preventing it from rotating. This ensures that the lifting column 23 will not slip under swaying conditions, and avoids the problem of the universal ball 25 loosening, which would cause the laser leveling device 3 to loosen and change its angle. When it is necessary to adjust the angle of the laser leveling device 3, the locking nut is turned in the opposite direction, allowing the adjusting knob 22 to rotate freely. The adjusting knob 22 can then be used to adjust the lifting column 23 and change the tightness of the universal ball 25, thereby enabling the adjustment of the angle of the laser leveling device 3 and improving the stability of the laser leveling device 3 angle.

[0045] Furthermore, a lower elastic block 28 is provided at the top of the lifting column 23, an upper elastic ring 29 is provided between the top surface of the universal ball 25 and the adjustment box 21, the universal ball 25 is located between the upper elastic ring 29 and the lower elastic block 28, and an arc groove is provided in the middle of the lower elastic block 28.

[0046] Specifically, in this embodiment, the universal ball 25 is clamped by the upper elastic ring 29 and the lower elastic block 28. The elastic element is elastic and its material can be silicone. When the upper elastic ring 29 and the lower elastic block 28 are compressed, they deform and exert force on the universal ball 25, thereby pressing the universal ball 25 so that the universal ball 25 cannot rotate. The lower elastic block 28 has an arc groove in the middle, and the universal ball 25 is limited in the arc groove, effectively avoiding the problem of the universal ball 25 shifting.

[0047] Furthermore, the top and bottom ends of the lifting column 23 are respectively provided with guide platforms 210, the outer wall of the guide platform 210 is in contact with the inner wall of the adjustment box 21, and a compression spring 211 is also provided between the guide platform 210 at the top of the lifting column 23 and the universal ball 25.

[0048] Specifically, in this embodiment, guide platforms 210 are respectively provided at the top and bottom of the lifting column 23. The outer wall of the guide platform 210 is in contact with the inner wall of the adjustment box 21. The guide platform 210 is limited and guided by the inner wall of the adjustment box 21. When the lifting column 23 slides up and down, the guide platform 210 can ensure that the movement direction of the lifting column 23 remains vertical and does not deviate, further improving the stability and reliability of the structure. A compression spring 211 is provided between the guide platform 210 at the top of the lifting column 23 and the universal ball 25. The compression spring 211 can use its elastic potential energy to compress the universal ball 25, ensuring the universal ball 25 is under pressure, further improving the stability of the structure.

[0049] Furthermore, an elastic rubber ring 212 is provided between the adjustment knob 22 and the adjustment box 21.

[0050] Specifically, in this embodiment, when the locking nut 27 is rotated to tighten the adjusting knob 22 via the drive shaft 221, the adjusting knob 22 is pressed against the outer wall of the adjusting box 21 by the elastic rubber ring 212, thereby avoiding friction damage between the adjusting knob 22 and the adjusting box 21 and effectively protecting the structure from damage. At the same time, the elastic rubber ring 212 can increase the strength of tightening the adjusting knob 22 and can effectively prevent the adjusting knob 22 from sliding between the adjusting box 21 and causing loosening.

[0051] Furthermore, an operating handle 213 is provided at the bottom of the mounting platform 24.

[0052] Specifically, in this embodiment, when it is necessary to adjust the angle of the laser leveling device 3, the angle of the laser leveling device 3 can be adjusted by holding the operating handle 213, which makes the operation more convenient.

[0053] Furthermore, the support frame 1 includes a support column 11, an operating ring 12, a locking element 13, three linkage rods 14, and three support legs 15;

[0054] The operating ring 12 is sleeved on the outer periphery of the support column 11, and the operating ring 12 is slidably connected to the support column 11. The three support legs 15 are arranged circumferentially at the bottom end of the support column 11, and one end of the support leg 15 is hinged to the support column 11.

[0055] One end of each of the three linkage rods 14 is hinged to the operating ring 12, and the other end is hinged to the middle of the support foot 15.

[0056] The locking member 13 is disposed on the operating ring 12, and the locking member 13 is used to lock with the support column 11 to lock the operating ring 12.

[0057] Specifically, in this embodiment, the support leg 1 can be unfolded and folded. When the user is moving this laser leveling device, the support leg 15 can be folded up for easy handling and storage. It can be unfolded when needed. Specific operation: The locking member 13 is used to lock the operating ring 12 onto the support column 11. When it is necessary to move the operating ring 12, the locking member 13 must be released first, and then the operating ring 12 can be slid. The movement of the operating ring 12 will drive the middle part of the support leg 15 through the linkage rod 14, thereby causing the support leg 15 to rotate around its hinge point with the support column 11, thus achieving the purpose of folding or unfolding. After the support leg 15 is unfolded or folded, the locking member 13 locks the operating ring 12 onto the support column 11 to prevent the support leg 15 from swinging due to the random sliding of the operating ring 12. The operation is simple and convenient.

[0058] Furthermore, the top surface of the operating ring 12 is circumferentially arranged with a plurality of clamping pieces 121, the support column 11 is slidably disposed on the inner side wall of the clamping piece 121, the outer wall of the clamping piece 121 is provided with threads, the thickness of the clamping piece 121 gradually increases from top to bottom, the locking member 13 is sleeved on the outer circumference of the clamping piece 121, and the locking member 13 is threadedly connected to the clamping piece 121.

[0059] Specifically, in this embodiment, since the thickness of the clamping piece 121 gradually increases from top to bottom, the clamping force of the clamping piece 121 on the support column 11 can be changed by screwing the locking member 13. When the locking member 13 is screwed upward, the clamping force of the clamping piece 121 on the support column 11 decreases, and the operating ring 12 can be slid, thereby enabling the support foot 15 to unfold or fold. When it is necessary to lock the angle of the support foot 15, the locking member 13 can be screwed downward, and the clamping force of the clamping piece 121 on the support column 11 will increase, thereby preventing the operating ring 12 from sliding, thus locking the angle of the support foot 15 and preventing loosening.
