Abstract

The invention relates to a laser level meter which comprises a transparent casing and two fixed rotating shafts, wherein each fixed rotating shaft is orthogonal with a symmetry axis in the vertical direction of the casing; the two fixed rotating shafts are mutually orthogonal; a heavy bob is pivoted to each fixed rotating shaft; at least one laser transmitter is arranged on the side face of each heavy bob; laser transmitted by each laser transmitter is parallel to a swing plane of the heavy bob and is orthogonal to a medial axis of the heavy bob; the laser transmitted by each laser transmitter irradiates on a transparent graduated disk which is arranged on the inner wall of the casing and corresponds to each laser transmitter. According to the laser level meter disclosed by the invention, the inclination angle of an object can be measured conveniently and accurately, and accurate measurement for top irregular objects can be realized.

Description

A kind of laser leveler

Technical field

The present invention relates to a kind of ergonomic measuring tool, especially, is a kind of level meter.

Background technology

Level meter conventional in current engineering survey is air-bubble level, in use, places it in testee top, observes the distance of bubble disalignment, thus judges that object to tilt how many angles relative to vertical.This instrument in use can not accurately measure angle of inclination, and not easily measures the irregular object in some tops.

Summary of the invention

For the problems referred to above, the object of this invention is to provide a kind of laser leveler, this invention can facilitate, measure inclined angle of object accurately, also can realize Measurement accuracy to top irregularly shaped object.

For solving the problem, technical scheme of the present invention is: this laser leveler comprises transparent shell, two fixed rotating shafts, and each described fixed rotating shaft is orthogonal with the axis of symmetry of housing vertical direction respectively, and two fixed rotating shafts are mutually orthogonal; The each pivot joint of each described fixed rotating shaft one piece of weight; Be provided with at least one generating laser in the side of each described weight, the laser of described laser transmitter projects is parallel to the swinging plane of weight, and is orthogonal to the axis of weight; The laser of each described laser transmitter projects is radiated on the transparent scale dish corresponding with each described generating laser in described inner walls.

As preferably, each described generating laser is placed on the top of weight side; Like this, weight is in swing process, and the displacement amplitude of generating laser is less, so that index dial arranges scale more easily.

As preferably, each described weight Side symmetrical places two generating lasers, and the laser of described laser transmitter projects is parallel to the swinging plane of weight, and is orthogonal to the axis of weight; So that carry out reading from all directions of described housing.

As preferably, described housing is rectangular in body; So that tested plane is close on the surface of all directions of housing.

As preferably, described index dial is formed by being atomized acrylic board, and groove is engraved in one side atomization acrylic plate deviating from described generating laser.

The invention has the beneficial effects as follows: when uprightly being placed by laser leveler, weight points to gravity direction, and now the laser of laser transmitter projects irradiates on zero groove of described index dial; When object measured by needs, laser leveler is placed on object upper flat region, or abutted against flattened region, object side, at this moment each weight rotates around each fixed rotating shaft and remains on gravity direction, each described generating laser rotates with weight, the laser of each described laser transmitter projects points to a certain numerical value on index dial corresponding to generating laser respectively, and these two numerical value are object angle of inclination relative to gravity direction in the rotational plane of weight; Object level can be realized according to angle of inclination adjustment object.This laser level structure is simple, and handled easily, accurately can read inclined angle of object, and less by the impact of testee shape.

embodiment:

Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail.

Embodiment one

In embodiment one shown in Fig. 1 to Fig. 3, this laser leveler comprises transparent pane body housing 1, two fixed rotating shafts X, Y, and each described fixed rotating shaft X, Y are orthogonal with the axis of symmetry of housing 1 vertical direction respectively, and two fixed rotating shafts X, Y are mutually orthogonal, the each pivot joint of each described fixed rotating shaft X, Y one piece of weight 3, weight 3 is positioned at the center of fixed rotating shaft X, Y, the part that each described weight 3 is connected with fixed rotating shaft X, Y is cylindrical, and lower end is conical, be provided with a generating laser 4 on the cylindrical lateral surface top of each described weight 3, the laser 41 that described generating laser 4 is launched is parallel to the swinging plane of weight 3, and is orthogonal to the axis of weight 3, the laser 41 that each described generating laser 4 is launched is radiated on the transparent scale dish 5 corresponding with each described generating laser 4 on described housing 1 inwall, described index dial is formed by being atomized acrylic board, groove is engraved in one side atomization acrylic plate deviating from described generating laser, when laser is penetrated on acrylic board, because acrylic board is to the scattering atomizing of laser, whole index dial is illuminated, the position of laser direct irradiation is in highlighted state simultaneously, like this, reading is carried out under being convenient to the environment of night or various dark, without the need to reoffering other auxiliary lighting apparatus.

When uprightly being placed by this laser leveler, weight 3 points to gravity direction, and the laser 41 that now generating laser 4 is launched irradiates on the central groove of described index dial 5; When object measured by needs, object upper flat region can will be placed on bottom laser leveler, or laser leveler side is abutted against flattened region, object side, at this moment each weight 3 is around each fixed rotating shaft X, Y rotates and remains on gravity direction, each described generating laser 4 rotates with weight 3, the laser 41 of two generating laser 4 transmittings points to a certain numerical value on the index dial 5 of generating laser 4 correspondence respectively, and these two numerical value are object angle of inclination relative to gravity direction in the plane that weight 3 rotates place; As the weight 3 in Fig. 2 and Fig. 3, turn an angle along Y roller bearing and X roller bearing respectively; According to angle of inclination adjustment testee, the upper surface level of object can be realized.This laser level structure is simple, and handled easily, accurately can read inclined angle of object, and less by the impact of testee shape.

Embodiment two

In the embodiment two described in Fig. 4, with embodiment one unlike: each described weight 3 Side symmetrical of the present invention places two generating lasers 4, the laser 41 that each generating laser sends is penetrated on the index dial 5 of correspondence, directly can observe the data index dial from multiple angle, this structure can reading determine angle of inclination more easily.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
