Description

Technical Field

[0001] This utility model belongs to the field of laser measurement technology, and specifically relates to a laser level. Background Technology

[0002] A laser level is an optical measuring tool that uses laser to project a baseline to achieve high-precision spatial positioning. It can significantly improve the work efficiency and long-distance measurement accuracy in fields such as building construction, interior decoration, and equipment installation, and has become a standard instrument in modern engineering.

[0003] However, laser levels need to be placed on a flat surface to ensure measurement accuracy. In practice, it is sometimes necessary to place the level on a higher platform to assist in measurement, raise the level to keep it relatively level with the object, and use a tripod or wall mount to drill holes in the wall to place the level. Currently, most of the level on the market uses a separate bracket design, which has systemic defects such as low leveling efficiency, poor environmental adaptability, and insufficient structural reliability. It is relatively troublesome to use and there is a risk of it falling. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] See Figures 1-7 This utility model provides a laser level, including a base 1, a bracket 3 and a level body 2; The base 1 has a receiving groove 4, and the receiving groove 4 has a support shaft 5. The bottom of the level body 2 has a reference plate 6. The level body 2 can rotate around the reference plate 6 as an axis. The reference plate 6 is sleeved on the support shaft 5. The top of the support shaft 5 has a limiting block 7. The support shaft 5 also has an adjusting piece 8 that contacts the upper surface of the reference plate 6. The bottom of the adjusting piece 8 and the limiting block 7 has an adjustment distance 9. The adjusting piece 8 and the reference plate 6 are both provided with an inclined gap 10 between them and the support shaft 5. The bottom of the reference plate 6 is provided with a collar 11 (the collar 11 and the bottom of the reference plate 6 can be integrally molded, see...). Figure 7 The bracket 3 can be stored in the receiving groove 4. One end of the bracket 3 is hinged to the receiving groove 4, and the middle of the other end of the bracket 3 is sleeved in the collar 11.

[0020] The bracket 3 of the laser level can be stored in the receiving groove 4 of the base 1, and one end of the bracket 3 is hinged to the receiving groove 4 (e.g., Figure 5As shown, a rotating shaft can be used for connection, but this structure is not limited to. The bracket 3 rotates outward along the hinge 31, allowing the bracket 3 to be raised, which in turn drives the reference plate 6 to move. The reference plate 6 is fitted into the support shaft 5, and there is an inclined gap 10 between the reference plate 6 and the support shaft 5 (i.e., the diameter of the inner ring of the reference plate 6 is larger than the diameter of the support shaft 5; the specific diameter is set according to the specific situation). The inclined gap allows the reference plate 6 to tilt during the lifting process, cooperating with the bracket 3 to adjust the angle of the level body 2. The upper surface of the reference plate 6 contacts the adjusting plate 8, and there is a certain distance (i.e., adjustment distance 9) between the adjusting plate 8 and the bottom of the limiting block 7, which limits the lifting height and maximum angle of the level body 2 (the maximum angle is when the adjusting plate 8 contacts the bottom of the limiting block 7). Therefore, the level body 2 is also lifted (as shown). Figure 6 , 7 As shown, when it needs to be retracted, the bracket 3 rotates inward along the hinge 31 and is stored in the receiving slot 4. The tilt angle and lifting height of this device can be varied according to the settings of different machines.

[0021] When activated, the laser level emits a laser to display crosshairs. Raising the support 3 allows the level to project at an elevation angle, raising the horizontal line. This structural design eliminates the need for a separate support 3, enabling the product to raise the horizontal line for measurement while maintaining accuracy and convenience.

[0022] An angle limiting device is provided on the side of the bracket 3 near the collar 11. That is, the bracket 3 has angle limiting inclined surfaces 12 on both sides of the collar 11. After the angle limiting inclined surfaces 12 come into contact with the bottom surface of the level body 2, they can be locked at a specific tilt angle and are not easy to tip over.

[0023] This laser level not only allows for convenient angle adjustment but also enables 360° rotation of the main body 2. Except for the leveling disc, the main body 2 and the reference disc 6 are in a sliding fit relationship. The main body 2 can rotate around the reference disc 6 as its central axis to achieve 360° rotation (e.g., ...). Figure 8 (As shown).

[0024] Specifically, a support frame 13 can be installed inside the level body 2. The inner edge of the support frame 13 is slidably connected to the outer edge of the reference plate 6. A laser generator 14 is also installed inside the level body 2.

[0025] In a preferred embodiment, the level body 2 also includes a housing 15, which is fitted over the support frame 13.

[0026] In a preferred embodiment, the front end of the outer casing 15 is provided with a laser glass window 16.

[0027] In a preferred embodiment, an instrument switch 17 is provided on one side of the housing 15.

[0028] In a preferred embodiment, a charging port 18 is provided on one side of the housing 15.

[0029] In a preferred embodiment, the top of the housing 15 is provided with a function adjustment button 19.

[0030] See Figure 1 , 2 As one implementation of this solution, the laser level adopts an integrated design of base 1, bracket 3, and level body 2. When the bracket 3 is stored, the base 1 and the bottom of the level body 2 are close together. The bottom of the level body 2 consists of a support frame 13 and a reference plate 6. The reference plate 6 is located in the middle of the support frame 13, and the inner edge of the support frame 13 is slidably connected to the outer edge of the reference plate 6. A laser generator 14 is located at the upper end of the reference plate 6 and is fixed on the support frame 13. A charging port (which can be a Type-C interface and connected to the circuit board on the support frame 13) is located on the left side of the support frame 13. An instrument switch (also connected to the circuit board on the support frame 13) is located on the right side of the support frame 13. A function adjustment button is located at the upper end of the support frame 13. The function adjustment button can be a push-button type, which connects to the relevant function circuit on the circuit board below when pressed. The circuit design is based on existing technology, and the above functions can all be implemented by existing technology, so they will not be described in detail here.

[0031] The integrated design of this utility model effectively avoids the cumbersome process of carrying and assembling an independent support 3, making it suitable for special construction scenarios. The device boasts strong overall integrity, facilitating transportation and storage, and enabling convenient "ready-to-use and deploy" operation. Once deployed, the angle limiting device of the support 3 reliably locks the level at a specific tilt angle, preventing it from tipping over. The support 3 works in conjunction with the rotation and tilting functions of the level body 2 to form a complete tilt measurement solution. Users can eliminate the need to create physical tilt references or rely on external auxiliary tools simply by operating this device, greatly simplifying the construction process for special projects such as stair railing installation and slope decoration. This allows a single person to quickly complete all operations, significantly reducing labor intensity and time costs, and improving construction efficiency.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
