[0020] 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.

[0021] Please see Figures 1-3A graduated laser level for climbing vines includes a base 1, which is circular in shape. A matching top cover 2 is nested on the base 1. The circular base 1 and top cover 2 fit together in a compact and smooth-rotating manner, supporting 360° omnidirectional measurement and adapting to complex construction environments. The outer edge of the top cover 2 is engraved with angle graduations 21 from 0-90°, allowing users to directly read the rotation angle without additional tools, achieving fast and accurate angle measurement. A transparent window 22 with a crosshair axis is located at the top center of the top cover 2 for easy centering and calibration, making it particularly suitable for scenarios requiring precise positioning.

[0022] A dual-axis bubble level 3 is integrated into the top of the cover 2, allowing users to simultaneously observe the horizontal and vertical states, thus improving leveling efficiency. The base 1 houses a mainboard 4, a laser emitter module 5, and a battery module 6. The laser emitter module 5 is electrically connected to the mainboard 4 via wires, and the battery module 6 powers the entire device. The laser emitter module 5 includes two laser emitters 51 located at the inner boundary of the base 1, maximizing the emission angle and reducing central obstruction. The dual emitters can achieve more uniform coverage through intersecting beams, reducing blind spots.

[0023] In this embodiment, angle scale 21 is directly etched on the outer edge of the upper cover 2, and a transparent window 22 with a central crosshair axis is used to achieve simultaneous angle measurement and laser positioning, reducing repetitive positioning processes. The nested structure of the circular base 1 and the upper cover 2 allows the dual-axis bubble level 3 and the laser emitter module 5 to form a spatially orthogonal layout. Combined with the intelligent control of the mainboard 4, different measurement modes can be switched.

[0024] The bottom of the base 1 is equipped with a wall-climbing adsorption mechanism 7, which allows the equipment to be firmly adsorbed onto surfaces such as walls, glass, and metal, freeing up the user's hands and adapting to high-altitude or narrow space operations.

[0025] Specifically, the wall-climbing adsorption mechanism 7 includes an air pump 71 installed inside the base 1. A bottom protective cover 72 is installed at the bottom of the base 1, and EPDM foam 73 is installed inside the bottom protective cover 72. The air pump 71 is connected to the internal cavity of the EPDM foam 73 via a hose. The elasticity of the EPDM foam 73 allows it to be compressed during air extraction, further reducing the cavity volume and enhancing sealing. Its porous structure does not directly participate in gas storage or extraction, but rather serves as a sealing medium and buffer layer, adapting to minor unevenness on the wall surface. The base 1 is equipped with a check valve structure 74 and a release button 75. The check valve structure 74 is connected to the air pump 71 via a hose, and a rubber sheet is placed inside the check valve structure 74. The release button 75 is used to release the adsorption state.

[0026] During adsorption, the entire device and bottom protective cover 72 are attached to the wall. The suction pump 71 is activated, drawing air from the internal cavity of the EPDM foam 73 through a hose, reducing the internal air pressure. As the air pressure decreases, the EPDM foam 73 is compressed and deformed, causing the bottom protective cover 72 to fit tightly against the wall, forming an initial seal. The suction pump 71 continues to draw air, creating a negative pressure inside the EPDM foam 73. The external atmospheric pressure firmly presses the entire device against the wall. The check valve structure 74 is closed to prevent backflow of air. The elastic seal of the EPDM foam 73 ensures that the vacuum level does not decrease, and the device is firmly adsorbed onto the wall by the pressure difference between atmospheric pressure and the internal vacuum.

[0027] When the adsorption is released, press the degassing button 75. External air quickly enters the internal cavity of the EPDM foam 73, the internal and external air pressures are restored to balance, the EPDM foam 73 returns to its original shape, the bottom protective cover 72 separates from the wall, and the equipment can be moved or removed freely.

[0028] In addition, the transparent window 22 is made of high-strength transparent material, namely polycarbonate (PC), which is impact-resistant and has good light transmission. A removable battery cover 8 is provided on the outer side of the base 1 corresponding to the battery module 6.

[0029] 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.
