Description

Laser Line Marker

Technical field

The utility model relates to a kind of Laser Line Marker, is used for engineering, building decoration aspect level, vertical reference face and to top, the mensuration of reference point over the ground, belongs to the laser surveying instrument technical field.

Background technology

Be widely used in the Laser Line Marker of engineering survey, building decoration aspect at present, mainly comprise casing assembly, rotating base assembly, suspension gear, the laser module constitutes.Wherein suspension gear is by the cross assembly, the suspention bearing assembly that inner and outer ring or joint spider constitute, the weight assembly is formed, the suspention bearing assembly that inner and outer ring or joint spider constitute connects solid through vertical columns and rotating base assembly, cross assembly lower end is connected with the weight assembly, the radium-shine module of top fixed laser of cross assembly, cross assembly under the laser module is connected suspention with the suspention bearing assembly that inner and outer ring or joint spider constitute, the vertical and horizontal suspention axle fulcrum of the suspension gear of the Laser Line Marker of this structure is in the medium position of cross assembly, utilizes universal gravitation to rely on the gravity of weight self to realize the automatic leveling of instrument.But because the cross modular construction in this Laser Line Marker is complicated, the requirement on machining accuracy height, form the variation of concentric reducer behind the fixing different laser module, the directly swing of influence suspention axle, precision quality is not easy to improve, for this reason, need constantly to regulate mass ratio up and down, to guarantee the reseting precision of suspension gear.Cause the assembly technology complexity, poor stability once assembles qualification rate and has only about 65 percent, causes a large amount of discards of reprocessing, and makes the cost cost high.

Summary of the invention

The purpose of this utility model is in the medium position of cross assembly because of the vertical and horizontal suspention axle fulcrum in its suspension gear at existing Laser Line Marker, thereby exist the cross modular construction complicated, the requirement on machining accuracy height, the assembly technology complexity, poor stability, it is low once to assemble qualification rate, cause a large amount of discards of reprocessing, make the high deficiency of cost cost, provide simple in structure, can simplify assembly technology, a kind of Laser Line Marker that helps improving reseting precision and stability and reduce the cost cost.

The purpose of this utility model is achieved through the following technical solutions, a kind of Laser Line Marker, mainly comprise casing assembly, rotating base assembly, suspension gear, vertically constitute to the laser module to laser module and level, wherein suspension gear is by the cross assembly, the suspention bearing assembly, the weight assembly is formed, the suspention bearing assembly connects solid through column and rotating base assembly, the fulcrum that it is characterized in that the cross assembly is arranged on nearly upper end, the suspention bearing assembly is connected suspention with the fulcrum of cross assembly upper end, and fixed vertical is to the laser module on the cross assembly below the fulcrum.

The utility model is the change to suspension point structure in the existing Laser Line Marker suspension gear, be arranged on nearly upper end by fulcrum with cross assembly in the suspension gear, the suspention bearing assembly is connected suspention with the fulcrum of cross assembly upper end, fixed vertical is to the laser module on the cross assembly below the fulcrum, overcome fully in the existing structure and constantly regulated the technical matters of mass ratio up and down because of vertically being arranged on the needs that bring on the above cross assembly of fulcrum to the laser module, the suspension gear center of gravity moves down, the assembly technology advantages of simple, the swing reseting precision that helps instrument increases substantially, one time the index qualification rate can reach more than 90 percent, greatly reduce repair rate, saved production cost, help saving energy and reduce the cost, the utility model is rational in infrastructure, dependable performance, not only improve the precision and the class of product, also improved economic benefit.
