Abstract

The utility model discloses a four-head multidirectional laser ground line instrument, which belongs to an instrument for drawing straight lines in buildings, in particular to the laser ground line instrument. The four-head multidirectional laser ground line instrument comprises laser generators, a base and a top cover, wherein the laser generators can emit linear laser beams, and a battery power supply device is arranged inside the base. The four-head multidirectional laser ground line instrument is characterized in that the T-shaped top cover is fixed in the center position of the base via screw threads through a central shaft rod, the tail parts of the laser generators are provided with sleeve rings to be sheathed on the central shaft rod arranged between the top cover and the base, the four laser generators can freely rotate around the central shaft rod in the same plane, and in addition, the periphery of the top cover is marked with angles, so crossed vertical lines and bisectrixes of any angle can be conveniently and fast drawn, the drawing and the reference of horizontal lines of the buildings are convenient, the precision is improved, the use is flexible and convenient, and the applicable places are wide.

Description

The multidirectional laser ground wire of four-head instrument

Technical field

The utility model belongs to the instrument of describing straight line in the building, particularly laser ground wire instrument.

Background technology

Paste timber floor in interior decoration, ceramic tile, marble, during wall brick etc., often use laser ground wire instrument, but existing laser ground wire instrument can only be dispersed the part straight line of certain angle, it is a kind of laser leveler of utility model patent of 200620071423.3 that China Patent No. is also arranged, comprise that both sides intersect vertically and the bottom surface is the base on plane, on the both sides that intersect vertically, be respectively equipped with perpendicular laser lamp socket, the laser lamp that can penetrate the laser rays that intersects vertically is installed in the laser lamp socket, the laser lamp socket is installed on the base, the corresponding horizon equipment in both sides that the laser lamp socket is provided with and intersects vertically, be provided with the 3rd laser lamp socket with position, laser lamp socket angle at 45 respectively, the laser lamp at the laser rays angle at 45 of the laser rays of ejaculation and all the other two laser lamps is installed in the 3rd laser lamp socket.In the utility model when work,, it is 90 ° mean line that three laser generators could be launched maximum angle, and promptly the angle of three laser beams is 45 °, can not change the angle between the laser beam arbitrarily.

The utility model content

In order to overcome the deficiency that existing laser ground wire instrument can not be launched the multi-angle ray, the utility model provides the multidirectional laser ground wire of a kind of four-head instrument, and the multidirectional laser ground wire of this four-head instrument is not only simple in structure, and easy to use, can to around launch ray at any angle, applied widely.

The technical scheme that its technical matters that solves the utility model adopts is: the multidirectional laser ground wire of a kind of four-head instrument, comprise the laser generator that to launch linear beam, there is the base of battery power supply inside, top cover, its structure is: the top cover of T shape is fixed on the base center by central shaft with screw thread form, the afterbody of described four laser generators has the collar to be socketed on the central shaft between top cover and the base, periphery at described top cover indicates angle, the both positive and negative polarity power supply plug of projection is arranged at the bottom of described four laser generators, is socketed in the groove type both positive and negative polarity of annular of base upper surface.

The multidirectional laser ground wire of above-mentioned four-head instrument, its structure is: there is switch the front end side of described laser generator.

The multidirectional laser ground wire of above-mentioned four-head instrument, its structure is that level meter is arranged on top cover.

The multidirectional laser ground wire of above-mentioned four-head instrument, home position has magnet in described base bottom.

The beneficial effects of the utility model are that the afterbody of described four laser generators has the collar to be socketed on the central shaft between top cover and the base, can rotate around circle core shaft like this, and angle is arranged on top cover, so just can be towards the intersection Laser emission straight line that adjusts five equilibrium from all directions, and the both positive and negative polarity power supply plug of projection is arranged at the bottom of four laser generators of the present utility model, be socketed in the groove type both positive and negative polarity of annular of base upper surface, this design is ingenious rationally, can also make things convenient for laser generator to rotate arbitrarily when can guarantee power supply, described base bottom home position has magnet, can conveniently be adsorbed on the metal objects, convenient horizontal drafting and reference improve degree of accuracy, can satisfy the accurately work of alignment of any requirement, such as being widely used in interior decoration, door and window is installed, pipeline laying, and equipment is installed, in ground laying and the constructing tunnel, be a kind of construction benchmark instrument rapidly and efficiently; The standardization five equilibrium that can also be applied to simultaneously hotel's dining table tableware such as puts at the workplace.
