Description

[0001] The utility model relates to the field of geodetic instrument manufacturing, in particular laser-based devices for creating reference axes intended for surveying in construction, for the assembly of technical equipment in the mechanical engineering industry, and in other industrial sectors where the use of a light plane and the transfer of markings in horizontal and vertical planes are required. A known line laser comprises a housing, a self-leveling platform with laser emission sources installed on it, lenses for converting the laser beams into a plane, a power supply and control system, and a mounting element for a tripod with an integrated 1 / 4-inch thread.

[0002] However, the design of the known line laser does not allow for the marking of uniform sections on the work surface. The most technically similar device with comparable functionality and effect, and which can be considered the closest analogue, is a line laser that includes a housing, a self-leveling mechanism, a laser emitter with a diffractive optical element, a power supply and control system, and a mounting bracket for a tripod.

[0003] However, the design of the known line laser has a narrow beam angle of the laser beam, which significantly limits the marking area, and the quality and intensity of the output from reference axes is low, which further reduces the application range of the device.

[0004] The purpose of the present utility model is to create a reliable device that enables the marking of uniform sections without compromising the quality and application range of a classic level, thereby expanding the application range of the line laser.

[0005] The technical result that solves the problem consists of equipping the line laser with laser emission sources and lenses for converting the laser beams into reference axes, wherein the laser emitter with the diffractive optical element is arranged orthogonally to each lens for converting the laser beams and the projections they emit are coaxial with the projection of the diffractive optical element.

[0006] Furthermore, the applicant set himself the task of providing the arsenal of tools used in the construction and assembly of engineering structures where the projection of axes and the transfer of markings in horizontal and vertical planes are required. Consequently, the additional technical result consists in the achievement of this purpose.

[0007] The stated task is achieved by equipping the line laser, which includes a housing, a self-leveling mechanism, a laser emitter with a diffractive optical element, a power supply and control system, and a mounting element for a tripod, with laser emission sources and lenses for converting the laser beams into reference axes, in accordance with the utility model application, wherein the laser emitter with the diffractive optical element is orthogonal is arranged for each lens to convert the laser beams and the projections they emit are coaxial with the projection of the diffractive optical element.

[0008] Investigations into patent applications and scientific and technical information sources show that the proposed line laser is unknown and therefore meets the criterion of "novelty".

[0009] The proposed line laser can be manufactured in any company specializing in this industry, as it requires well-known materials and standard equipment that are produced on a large scale by both domestic and foreign manufacturers.

[0010] This means that the specified laser level meets the criterion of "industrial applicability".

[0011] The proposed combination of essential features gives the specified laser level new properties that make it possible to solve the tasks set out, namely the creation of a reliable device that enables the marking of equal length sections without compromising the quality and application range of a classic level.

[0012] The claimed line laser thus meets the criterion of "industrial applicability". The proposed set of essential features gives the claimed line laser new properties that make it possible to solve the stated tasks, namely the creation of a reliable device that enables the marking of uniform sections without compromising the quality and application range of a conventional level.

[0013] Equipping the line laser with additional laser emission sources allows for an increase in the working range and the quality of the reference axis projections. Furthermore, the arrangement of the lenses for converting the laser beams into reference axes orthogonal to the laser emitter with the diffractive optical element, so that the projections they emit are coaxial with the projection of the diffractive optical element, makes it possible to avoid the eccentricity of the projections of the cylindrical lens with the diffractive optical element, thus ensuring the required uniformity of the sections in the work.

[0014] Thus, the totality of the essential features of the proposed line laser enables the achievement of the stated technical result, namely the equipping of the line laser with laser emission sources, lenses for converting the laser beams into reference axes, wherein The laser emitter with the diffractive optical element is arranged orthogonally to each lens for converting the laser beams, and the projections it emits are coaxial with the projection of the diffractive optical element. The proposed utility model is explained by the drawings: In Fig. - General view of the line laser in projection with a section and view of the projections. Fig.- Functional diagram of the optical elements of the line laser. The line laser comprises a housing 1, a self-leveling mechanism 2, a laser emitter 3 with a diffractive optical element 4, a power supply 5 and control system 6, a mounting element 7 for a tripod, laser emission sources 8, and lenses 9 for converting the laser beams into reference axes. The laser emitter 3 with the diffractive optical element 4 is arranged orthogonally to each lens for converting the laser beams, and the projections they emit are coaxial with the projection of the diffractive optical element 4. The line laser is used as follows: Before starting work with the specified laser level, it must first be mounted on a tripod or other accessory. The type of mounting is determined by the working conditions and the availability of mounting options.

[0015] Example 1: The pre-attached and switched-on level is aligned with the selected work surface. The simultaneous operation of the laser beams with cylindrical lens and diffraction element is selected. Then, equal-length sections are marked for subsequent installation, for example, of a metal frame made of guides. It is possible to mark a larger number of guides during a single installation of the level.

[0016] Example 2: The pre-attached and switched-on level is aligned with the selected work surface, the operation of the diffraction element with the net projection is selected, creating the possibility to distribute, for example, furniture, pictures, shelves, etc. evenly on the work surface.
