To ensure accuracy, laser levels typically require fine-tuning capabilities, allowing for minor adjustments when mounted on a tripod or other support system.
[0003] Traditional laser levels often face technical challenges and limitations when performing center fine-tuning. For example, some fine-tuning structures, due to a lack of reasonable motion trajectory planning, are prone to center position shifts during fine-tuning, thus affecting measurement accuracy. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a center fine-tuning structure for a laser level.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] A center fine-tuning structure for a laser level includes a rotating base with a base cover, and the level body is mounted on the base cover.
[0007] The base cover has an integrally formed fine-adjustment opening on its top rear side and an integrally formed stroke restriction opening on its top front side. The stroke restriction opening and the fine-adjustment opening are concentric arc-shaped structures.
[0008] The top of the rotating base is provided with an integrally formed housing part corresponding to the fine adjustment port. The housing part extends into the fine adjustment port and is adapted to the fine adjustment port.
[0009] A fine-tuning moving component is provided inside the fine-tuning movable port, and the fine-tuning moving component drives the housing part to move inside the fine-tuning movable port;

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 A center fine-tuning structure for a laser level includes a rotating base 1, which is used to mount the entire device on a tripod or other support structure. A base cover 2 is provided on the rotating base 1, and the level body 3 is mounted on the base cover 2.
[0024] The top rear side of the base cover 2 is provided with an integrally formed fine-tuning opening 4, and the top front side of the base cover 2 is provided with an integrally formed travel limiting opening 5. The travel limiting opening 5 and the fine-tuning opening 4 are concentric arc structures. A fine-tuning slider 8 is slidably connected inside the travel limiting opening 5. The movement trajectory of the fine-tuning slider 8 is consistent with the arc direction of the travel limiting opening 5. The fine-tuning slider 8 is fixedly connected to the rotating base 1. This concentric arc design makes the movement trajectory of subsequent components more accurate and stable, providing a basis for achieving precise center fine-tuning. The top of the rotating base 1 is provided with an integrally formed housing part 6 corresponding to the fine-tuning opening 4. The housing part 6 extends into the fine-tuning opening 4 and is adapted to the fine-tuning opening 4; ensuring that the relative movement between the rotating base 1 and the base cover 2 is smoother and more stable during fine-tuning. Among them, a fine-tuning moving component 7 is provided inside the fine-tuning opening 4, and the fine-tuning moving component 7 drives the housing part 6 to move within the fine-tuning opening 4.
[0025] The aforementioned structure, through the concentric arc-shaped fine-tuning port 4 and travel-limiting port 5, and the synergistic effect of the fine-tuning moving component 7 and the fine-tuning slider 8, enables the rotating base 1 to rotate precisely relative to a fixed center. Since the device is fixed to the tripod via the rotating base 1 during use, the base cover 2 actually moves relative to the rotating base 1, thereby achieving fine-tuning of the center position of the level body 3. This rotational movement around a fixed center effectively avoids the center position offset problem caused by inconsistent motion trajectories in traditional fine-tuning structures, greatly improving the measurement accuracy of the laser level.
[0026] like Figure 1 , 3As shown, the fine-tuning moving assembly 7 includes a hammer nut 71, with a screw 72 threadedly connected to the hammer nut 71. Both ends of the screw 72 are threadedly fixed to the sides of the base cover 2. A nut fastening sleeve 73 is fitted to the outer side of the hammer nut 71, and the screw 72 is inserted into the nut fastening sleeve 73. The nut fastening sleeve 73 is located inside the housing portion 6, with its sides near the ends of the screw 72 fitting against the inner wall of the housing portion 6. The housing portion 6 has insertion ports 61 on its sides near the ends of the screw, through which the screw 72 is inserted. By rotating the screw 72 in conjunction with the limiting positions of other structures, the hammer nut 71 moves along the extension direction of the screw 72, and the housing portion 6 moves within the fine-tuning movable opening 4 via the transmission of the nut fastening sleeve 72.
[0027] In addition, knobs 74 are fixedly connected to both ends of the screw 72 for easy rotation by the operator. The size of the insertion port 61 is larger than the diameter of the screw 72. This ensures that the screw 72 can smoothly drive the sleeve part 6 to move along the trajectory of the fine-tuning movable port 5 during rotation.
[0028] Furthermore, a protrusion 9 is provided on the top of the rotating base 1 corresponding to the fine-tuning slider 8. The protrusion 9 extends into the travel limit port 5, and the fine-tuning slider 8 is fixedly connected to the protrusion 9 by screws. During fine-tuning, the fine-tuning slider 8 slides within the travel limit port 5, serving to limit and guide, ensuring that the rotating base 1 is fine-tuned according to the predetermined trajectory, further improving the accuracy and stability of center fine-tuning. Moreover, the travel limit port 5 and the fine-tuning slider 8 are in two sets, further enhancing the stability and balance during the fine-tuning process.
[0029] Working Principle: When fine-tuning the center position of the laser level is required, the operator rotates the knobs 74 at both ends of the screw 72, causing the screw 72 to rotate. Since the hammer nut 71 is threadedly connected to the screw 72, according to the principle of threaded transmission, the hammer nut 71 will move along the axial direction of the screw 72. The nut fastening sleeve 73 on the outside of the hammer nut 71 cooperates with the housing part 6, allowing the hammer nut 71 to drive the housing part 6 to move within the fine-tuning port 4 during its movement. Because the housing part 6 and the rotating base 1 are integrally formed, the rotating base 1 will move accordingly with the movement of the housing part 6. Since the housing part 6 and the rotating base 1 are integrally formed, and the rotating base 1 is fixed on the tripod in a fixed position, it is actually the base cover 2 that moves relative to the rotating base 1, thereby achieving fine-tuning of the center position of the level body 3.
[0030] During fine-tuning, the fine-tuning slider 8, fixedly connected to the rotating base 1, slides within the travel limit opening 5. The arc-shaped structure of the travel limit opening 5 defines the movement trajectory of the fine-tuning slider 8, thereby limiting the range of motion of the rotating base 1, ensuring the stability and accuracy of the fine-tuning process, and preventing instrument damage or increased measurement errors due to excessive fine-tuning. Once the desired position is reached, stop rotating the knob 74. At this point, the center position of the laser level has been precisely adjusted to the required position, meeting the measurement requirements.
[0031] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
