The technical problem to be solved in the present invention provides a kind of multi-thread Laser Line Marker simple in structure, with low cost, and its body has Installation and Debugging convenient and processing and the easy characteristics that ensure of installation accuracy.
In order to solve the problems of the technologies described above, the invention provides a kind of multi-thread Laser Line Marker and comprise body, this body comprises: the vertical laser seat, the top of this vertical laser seat is provided with the laser instrument mounting groove of four concave shapes of alternate 90 ° of distributions successively, and the top of this vertical laser seat is provided with the groove lid; Cover relative be provided with V-type groove or dovetail groove with each laser instrument mounting groove at this groove; The vertical laser of graticule instrument is located between described laser instrument mounting groove and described V-type groove or the dovetail groove.
For making things convenient for Installation and Debugging, the vertical line degree adjusting bolt hole that the bottom surface of described laser instrument mounting groove is provided with a carrying bolt hole and is located at these both sides, the place ahead, carrying bolt hole; Be provided with the carrying bolt for the trunk portion that supports described vertical laser in the carrying bolt hole, each vertical line degree is regulated the vertical line degree that is provided with in the bolt hole for the vertical line degree of regulating described vertical laser output laser and is regulated bolt.
For convenient direction of regulating each vertical laser output laser, be respectively equipped with direction on the side of described laser instrument mounting groove and regulate bolt hole, all directions are regulated the direction that is provided with in the bolt hole for the direction of regulating described vertical laser output laser and are regulated bolt.
The present invention further provides and a kind ofly need not to adopt counterweight can make the vertical laser seat be in the multi-thread Laser Line Marker of plumbness, it comprises the body gravity centre adjustment mechanism, and this body gravity centre adjustment mechanism comprises: be located at the vertical laser seat top of graticule instrument a pair of bearing pin mount pad, be located at this to the bearing pin on the bearing pin mount pad, the suspension holdfast that is rotatably connected on balancing shaft on this bearing pin, is rotationally connected with the two ends of this balancing shaft; The axis of the horizontal laser on the axis of described bearing pin and the described vertical laser seat be arranged in parallel; In when assembling, the axis of bearing pin is crossing with the body center of gravity line of graticule instrument with the intersection point of the axis of balancing shaft, the body barycentre offset of graticule instrument can be adjusted to zero.
Further, the axis of described bearing pin and the axis of described horizontal laser are crossing with the vertical center line of described vertical laser seat simultaneously, to guarantee the balance of bearing pin both sides.
Further, the top end face of the bearing pin mount pad on the described vertical laser seat is provided with the bolt for fixing described bearing pin.Namely when Installation and Debugging, only need the intersection point of the axis of bearing pin and the axis of the balancing shaft body center of gravity line with the graticule instrument is intersected, at once the body barycentre offset of graticule instrument is adjusted to zeroly, use the described bearing pin of bolt more at this moment, namely finish installation.
The present invention further provides the convenient and reliability of a kind of with low cost, Installation and Debugging base micro-adjusting mechanism of multi-thread Laser Line Marker preferably, it comprises: concentricity axle is base, fine tuning dish and the revolving bed of upper and lower settings successively; Fine tuning dish is provided with the non-rectangular channel that radially arranges; The central authorities of described base are provided with circular trough, the madial wall of this circular trough is provided with a chute, be provided with trimming bolt and the slide block of threaded engagement each other in this chute, the outboard end of trimming bolt extends the sidewall of described circular trough, and the top of described slide block extends in the rectangular channel on the described fine tuning dish.
Further, for guaranteeing that when finely tuning fine tuning dish is suitable for being provided with a plurality of around the equally distributed column of described central shaft in the described circular trough around described central shaft rotation; Also be provided with on the fine tuning dish around described central shaft evenly distribute and with the described column fan looping pit of corresponding setting one by one, and each column extends corresponding fan looping pit.
Further, for guaranteeing to have moderate damping force between described fine tuning dish and the base, to guarantee the stability of fine setting, be provided with fixed ring piece between described fine tuning dish and the revolving bed, this fixed ring piece is provided with and the top of the described column mounting hole by bolt.
Technique scheme of the present invention has the following advantages compared to existing technology: in the body of (1) multi-thread Laser Line Marker of the present invention, vertical laser seat and groove lid are two parts, and it can be by mould one-shot forming respectively during production; That is: when producing, the V-type groove that the laser instrument mounting groove of four concave shapes of the alternate 90 ° of distributions successively on the vertical laser seat and having is oppositely arranged with each laser instrument mounting groove or the groove of dovetail groove lid, can be by respectively one-shot forming of mould, so its production technology is simple and convenient relatively, precision ensures easily and with low cost.During use, only need the vertical laser of graticule instrument is located between described laser instrument mounting groove and described V-type groove or the dovetail groove, and debug by the bolt of 5 diverse locations, can guarantee service precision.(2) a pair of bearing pin mount pad on vertical laser seat top is movably connected on the support that is made of described balancing shaft and suspension holdfast by a bearing pin.The body center of gravity line of the intersection point of the axis of bearing pin and the axis of balancing shaft and graticule instrument intersects, therefore when assembling, be suitable for the body barycentre offset of graticule instrument is adjusted to zero, need not to adopt counterweight to adjust the body barycentre offset simultaneously, reduced production cost, made things convenient for installation and debugging.(3) when carrying out the angular setting of graticule instrument, earlier by directly rotate back to swivel base to roughly towards mode finish coarse adjustment, adjust the position of slide block then by the rotary fine adjustment bolt, and then driving fine tuning dish trace rotation, and drive the rotation of revolving bed trace, when arriving corresponding angle, stop.Because in the coarse adjustment process, the bottom of revolving bed only with fine tuning dish generation kinetic friction; In trim process, only fine tuning dish and base edge generation kinetic friction, the problem that it does not exist damping to lose efficacy; Lost efficacy in case therefore solved damping ring plate of the prior art, just can't realize the defective of fine adjustment function, guaranteed its reliability.And base micro-adjusting mechanism of the present invention is simple in structure, with low cost, has Installation and Debugging characteristics easily simultaneously.
