Abstract

The utility model discloses a simple laser gradienter. Two or more than two laser light sources (7) are installed on a horizontal ruler (1) which is connected with a vertical ruler (3) through a connecting device; the lower end of the vertical ruler is connected with a plane rotation device which is provided with an adjustable support. The device has low expense, convenient application, thus solving the actual need of the engineering.

Description

The simple laser level meter

Technical field:

The utility model relates generally to the level meter that uses on a kind of engineering, particularly a kind of simple laser level meter that uses laser technology.

Background technology:

Usually on engineering, often run into the occasion of usage level instrument, during the window frame in for example architectural installation house, if window frame is longer, can't determine directly whether it is in same horizontal level from installation base surface that must be far away with surveyor's staff, usually use a kind of indigenous method, promptly use a transparent hose of filling water to determine two horizontal situations, be on the same surface level so that the basis of same longer window frame is installed than distant positions.Chance at other similar occasion usage level instrument is also more; But general more valuable level meter must be used by the professional person.General simple engineering project can't be equipped.Therefore a kind of easy, level meter easy to use is to need in the reality.

Summary of the invention:

The simple laser level meter that provides a kind of expense cheap, easy to use is provided the purpose of this utility model.

For achieving the above object, scheme of the present utility model is: two or more laser lamps source is installed on the horizontal ruler, horizontal ruler links to each other with a vertical scale by coupling arrangement, vertically the lower end of scale links to each other with a plane whirligig, and the plane whirligig is provided with adjustable bearing.

Adopt such scheme, promptly can use this device very easily, the source that adds the laser lamp source has multiple, thereby expense is cheap, thereby has realized the purpose of this utility model.

Below by diagram and embodiment scheme is described in more detail.

Description of drawings:

Fig. 1 is the front elevation of simple laser level meter;

Fig. 2 is the side view of simple laser level meter;

Fig. 3 is the horizontal ruler front elevation of simple laser level meter;

Embodiment:

Simple laser level meter as shown in Figures 1 and 2, comprise a horizontal ruler (1), scale (1) is an angle square, the last right-angle side middle part of angle square has a groove (2), the width of groove (2) cooperates with the width of a vertical scale (3) is movable, so that horizontal ruler (1) can move with respect to vertical scale (3), as shown in Figure 3.Vertically the straight trough (4) that extends along microscler direction is dug in the centre of scale (3), and on microscler direction, be carved with scale, a screw rod (5) passes straight trough (4) and opens screw hole at another right-angle side of scale (1), tightens nut and gets final product relative fixed, and loosen nut is promptly removable.Because groove (2) cooperates with the width employing activity of vertical scale (3), the gap is very little, therefore can prevent that scale (1) from being the canting of the turning axle left and right sides with the center line of screw rod (5), thereby guarantee the levelness of scale (1).

The last right-angle side of scale (1), the both sides that are positioned at groove (2) also respectively have a straight trough (6), with fastener a laser lamp source (7) are housed respectively on straight trough.Any laser aid of prior art can be adopted in described laser lamp source (7), but have in mind from economical and practical, the laser lamp source of present embodiment is a kind of commercially available laser toy lamp, this is a kind of simple laser device that can send a branch of ruddiness, range can both capture its light beam within 0.5 km, price has only several yuans, therefore can reach the cheap purpose of expense of the utility model requirement.Described laser lamp source (7) is a kind of tubular device, and inside is one group of optical lens and lamp source, and the outside is connected to and makes its luminous supply unit, and present embodiment uses 6 volts electric battery.An associated self-control pedestal (8) is installed in the outside of tubular device so that link to each other with straight trough on the horizontal ruler (1) by fastener, the bottom surface of pedestal (8) should with the light place plane parallel of laser lamp source (7) ejaculation, this is understandable.

Vertically the top of scale (3) is equipped with air bubble apparatus (9), be used for the level of means for correcting, owing to when making this device, require to have between vertical scale (3) and the horizontal ruler (1) strict verticality requirement, so when bubble (9) expression is horizontal, that is to say that horizontal ruler (1) is horizontal.

Vertically lower end and a plane whirligig of scale (3) join.Described plane whirligig comprises the base (10) of a band garden dish projection, have a circle groove (11) on the garden periphery of dish type heave foundation (10), a vertical scale fixed mount (12) has pit to match with garden dish type projection, on the fixed mount (12) with pin put in the groove (11), so that vertically scale (3) rotates along the center of the base (10) of band garden dish projection, play adjusting position.

Vertically the lower end of scale (3) is connected with fixed mount (12) by fastener.

Upward also have one group of uniform leg (13) coupled at base (10).Three or four of leg (13) installations all can.In its foot lower margin is installed and adjusts screw (14), so that regulate the level of whole device.

Each parts should guarantee enough making precision and installation accuracy when making, so that can reach the technical conditions of matching requirements, this is understandable.

When using this device, for example to determine whether one section larger-size installation base surface is on the same surface level, this device can be arranged on the appropriate location of the basal plane that will detect, and make bubble be in middle position by adjusting leg, represent that promptly horizontal ruler is horizontal, power-on then, there is the light beam of two redness on basal plane, to scan, by connecting a straight line between 2 luminous points, promptly represent horizontal line, if basal plane conforms to straight line, represent that then basal plane is in level, otherwise need to adjust.

Adopt this device promptly can avoid using expensive surveying instrument, avoided the inconvenience of using indigenous method to bring again, solved need of real project.

In sum, the utility model is effective.
