Description

Technical Field

[0001] This utility model relates to the field of laser levels, and in particular to a laser level pendulum body. Background Technology

[0002] Laser levels are widely used for various horizontal, vertical, and angular measurements due to their high precision, intuitiveness, and portability. The pendulum, as the core component of the laser level, is mainly responsible for maintaining the stability and accuracy of the laser module.

[0003] Currently, in laser level pendulums, the laser module is installed in a pre-reserved groove on the pendulum body by bolts. After installation, the laser module is fine-tuned through multiple pre-reserved adjustment holes to determine the final installation position. Because the laser module is installed by bolts and then manually fine-tuned, its installation accuracy is difficult to guarantee, which in turn makes it difficult to guarantee the accuracy of the laser emitted by the laser module during subsequent use.

The first end of each receiving cavity has a protrusion, and the second end of each receiving cavity is an operating hole. The horizontal laser module and the vertical laser module are respectively provided with a vertical adjustment structure and a horizontal adjustment structure on the side facing the operating hole.

[0006] In one embodiment, the horizontal laser module and the vertical laser module include a mounting base, an adjusting nut movably mounted on the front end of the mounting base, and a lens mounted between the mounting base and the adjusting nut. The vertical adjustment structure or the horizontal adjustment structure is disposed on the side of the mounting base away from the adjusting nut and facing the operating hole.

[0008] In one embodiment, the horizontal laser module and the vertical laser module further include abutting springs at both ends that abut against the mounting base and the lens, respectively.

[0009] In one embodiment, the protrusion corresponding to the horizontal laser module is provided with a horizontal slot, and the protrusion corresponding to the vertical laser module is provided with a vertical slot.

[0025] This utility model provides a laser level pendulum body.

[0026] like Figure 1-3As shown, the laser level provided in this embodiment includes a pendulum body 10, a horizontal laser module 30, and a vertical laser module 20. The pendulum body 10 has two axially opened receiving cavities 11. The horizontal laser module 30 and the vertical laser module 20 are disposed in the receiving cavities 11. The first end of the receiving cavity 11 has a protrusion 12, and the second end of the receiving cavity 11 is an operation hole 13. The horizontal laser module 30 and the vertical laser module 20 are respectively provided with a vertical adjustment structure and a horizontal adjustment structure on the side facing the operation hole 13.

[0027] In this embodiment, the laser level pendulum includes a pendulum body 10, a horizontal laser module 30, and a vertical laser module 20. The pendulum body 10 has two axially oriented receiving cavities 11. The horizontal laser module 30 and the vertical laser module 20 are disposed within the receiving cavities 11. The first end of each receiving cavity 11 has a protrusion 12, and the second end of each receiving cavity 11 is an operation hole 13. The horizontal laser module 30 and the vertical laser module 20 are respectively provided with a vertical adjustment structure and a horizontal adjustment structure on the side facing the operation hole 13. Therefore, in this technical solution, the user can adjust the illumination light of the horizontal laser module 30 and the vertical laser module 20 at the operation hole 13 through the vertical and horizontal adjustment structures. Furthermore, since the adjustment is performed on the side away from the protrusion 12, it is very convenient to adjust them, improving convenience.

[0028] The horizontal laser module 30 and the vertical laser module 20 each include a mounting base 21, an adjusting nut 22 movably mounted on the front end of the mounting base 21, and a lens 23 installed between the mounting base 21 and the adjusting nut 22. The vertical adjustment structure or the horizontal adjustment structure is located on the side of the mounting base 21 opposite to the adjusting nut 22 and facing the operating hole 13. In this embodiment, the positions of the lasers emitted by the vertical laser module 20 and the horizontal laser module 30 can be adjusted using the vertical adjustment structure and the horizontal adjustment structure, respectively.

[0029] Specifically, the mounting base 21 includes an axially extending first connecting cylinder 24, the inner wall of which has a first connecting thread 241. The adjusting nut 22 includes an axially extending second connecting cylinder 25, the outer wall of which has a second connecting thread 251 that mates with the first connecting thread 241. The horizontal laser module 30 and the vertical laser module 20 also include abutment springs 26 at both ends abutting against the laser module body 27 and the lens 23, respectively, on the mounting base 21. The vertical and horizontal adjustment structures are used to change the position of the lens 23 through the engagement of the first connecting thread 241 and the second connecting thread 251, thereby adjusting the laser beam.

[0030] In the above embodiment, a horizontal slot 121 is provided on the protrusion 12 corresponding to the horizontal laser module 30, and a vertical slot 122 is provided on the protrusion 12 corresponding to the vertical laser module 20. The horizontal adjustment structure includes two first adjusting screws 31 connected to the mounting base 21, and the line connecting the two first adjusting screws 31 is perpendicular to the horizontal slot 121. The vertical adjustment structure includes two second adjusting screws connected to the mounting base 21, and the line connecting the two second adjusting screws is perpendicular to the vertical slot 122. When the horizontal laser module 30 and the vertical laser module 20 are turned on, the light emitted by them forms a cross. When it is necessary to adjust the height of the horizontal laser emitted by the horizontal laser module 30, only the two first adjusting screws 31 need to be adjusted to achieve the vertical adjustment of the horizontal laser. Correspondingly, when it is necessary to adjust the left and right position of the vertical laser emitted by the vertical laser module 20, only the two second screws need to be adjusted to achieve the left and right adjustment of the vertical laser.

[0031] In addition, the bottom of the pendulum body is provided with a threaded interface for connecting with external threads, which facilitates the installation of the laser level pendulum body.

[0032] It is understandable that the focus of this application is on how to adjust the position of the laser, while the emission of the laser (i.e. the working principle of the laser module) is not the direction of improvement of this application. At the same time, the working principle is also the prior art, and the laser module in the prior art can be directly adopted. Therefore, this application will not elaborate on it.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
