Description

A kind of laser level

Technical field

The utility model relates to a kind of device that is used for determining benchmark job face, is specifically related to a kind of laser level that is used to provide level and plumb datum.

Background technology

In building, decorative craft and other similar work, need to determine reference horizontal line, surface level and pedal line, vertical guide, various level meters have appearred thus, plumb aligner etc., at present, using more convenient then is laser level.

Laser level is used to provide horizontal line, pedal line, realizes operations such as orientation, location.Laser level commonly used is made of system of subject and support system, its system of subject mainly comprises vertical generating laser, horizontal laser light transmitter, vertical support frame, pendulum mass, interior ring, outer shroud and Anping system etc. in housing, the housing, and its support system mainly comprises micro-adjusting mechanism, base, supporting leg and holding turns.Send one to four vertical line by vertical laser during work, many vertical lines will constitute a cross curve very accurately at zenith, sending a fan angle by horizontal laser is the horizontal line of 120 degree, owing to have Anping system, so laser rays parallel with the vertical precision of being sent by instrument over the ground is very high, generally in ± 1mm/10m.Described system of subject is placed on the holding turns of support system, and system of subject can rotate freely on holding turns, cooperates micro-adjusting mechanism can make laser rays accurately aim at measured target.

At present the base of the laser level that uses is supported by the supporting leg of 3 outside extending obliquelies usually, and to guarantee the balance of main body, system of subject is positioned at the central authorities of support system.Therefore when need laser level to throw the vertical lasing area of metope, be subjected to the restriction of the supporting leg position of outwards stretching and be difficult to realization.

Summary of the invention

The utility model purpose provides a kind of can the support general work position realization stable equilibrium, can press close to the laser level that metope carries out work again.

For achieving the above object, the technical solution adopted in the utility model is: a kind of laser level, comprise system of subject, support system, described system of subject comprises housing, laser diode in the housing, support and Anping system, described support system is mainly by base, displacement disc, the translation locking mechanism, micro-adjusting mechanism and at least 3 supporting legs are formed, described system of subject is connected on the displacement disc by micro-adjusting mechanism, described displacement disc is connected with base by the translation locking mechanism, has the translation freedoms in the surface level between translation locking mechanism and base, and spacing by latch-up structure, described supporting leg is connected with base through the vertical plane angle adjustment mechanism.

Above, described micro-adjusting mechanism is used to regulate the relative position of system of subject, usually, in the prior art, system of subject is connected on the base by micro-adjusting mechanism, in the technique scheme, system of subject then is connected on the displacement disc by micro-adjusting mechanism, but the structure of micro-adjusting mechanism is identical with connected mode.The vertical plane at described supporting leg place can be regulated the angle with respect to base, and this adjustment structure for example can be that supporting leg is fixedlyed connected with base through the bolt that a vertical direction is provided with, and rotates supporting leg, can change the direction of supporting leg.Described translation locking mechanism make displacement disc relatively base adjust position and locking in the horizontal direction, have multiple structure to adopt at present, when selecting, consider installing space.

Optimized technical scheme, described translation locking mechanism comprises the fixed head of fixedlying connected with base, three retaining rings, disk and lock-screw, described base central authorities are provided with center pillar, fixed head is fixedlyed connected with middle column top, between base upper surface and fixed head, around the center pillar base plate of sheathed displacement disc successively, following retaining ring, middle retaining ring, upper locking ring and disk, constitute the translation gap between the base plate medium pore of displacement disc and the center pillar, in described on the retaining ring inner edge lower inclined plane respectively with upper locking ring, the outer rim inclined-plane contact matching of following retaining ring, lock-screw one end are butted on the middle retaining ring.

In the technique scheme, the housing of described system of subject is provided with two side covers, be provided with four horizontally disposed laser tubes in the described housing, the angle between adjacent laser tube is 90 degree, is respectively arranged with the laser tube that three spaces, 120 degree distribute along vertical guide in described each side cover.

In the technique scheme, the selection of laser tube, syndeton and control circuit are prior art, during work, instrument can be launched a surface level and two vertical guides, three lasing areas are vertical mutually, surface level is locked the linear laser butt joint of sending by four laser tubes that become 90 degree to distribute in the housing and is formed, and vertical guide is to be docked by three linear lasers that laser tube sent that become 120 degree to distribute in the side cover to form.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1, because support system of the present utility model has adopted travel mechanism, main body can move with respect to base, cooperates contractile supporting leg, make the vertical lasing area can press close to metope, construct, and this travel mechanism is simple in structure, not high to requirement on machining accuracy.

2, because the utility model can be launched a mutually perpendicular horizontal laser light face and two vertical lasing areas, the bearing accuracy height, and horizontal laser light face and vertical lasing area form by the common laser pipe, and simple in structure.
