Embodiment Construction

[0006] Such as figure 1 , figure 2 As shown, the outer ring 1 is U-shaped, and is installed on the base by a support rod, and the inner ring 2 is connected to the vertical rod for suspension; the outer ring 1 is connected to the same horizontal plane on both sides of the inner ring 2 through a rotating mechanism and is vertical. The rotating mechanism is a universal joint type, the rotating shaft 4 is set in the inner hole of the bearing 5 and is parallel to the axis center, the spacer ring 3 is connected to the rotating shaft 4 and one end withstands the inner ring inside the bearing 5, and the other end withstands the inner ring 2 , The hollow nut 6 withstands the outer ring on the outside of the bearing 5 . Rotating the hollow nut 6 can adjust the assembly gap, and can freely swing 360°, the rotation is flexible and stable, and the measurement accuracy is guaranteed.

Abstract

The present invention discloses an engineering measurement instrumentation which is a laser striping machine expansion cushion of a laser striping machine suitable for engineering project, building decorate ornament aspect horizontal / vertical base face and opposite vertex / ground reference point in measuring. An external ring (1) is fixed on a subbase by a support bar device, an inner ring (2) connects and hangs with a vertical rod; the external ring (1) is linked with two sides of the inner ring (2) on a same horizontal face and vertical. The instrumentation design a novel scientific cardan universal joint type compensation structure which can freely-swinging 360 degree, rotary movement flexible and stable, dependable performance for ensuring measurement precision and increasing progress and efficiency of construction greatly.

Description

Technical field: [0001] The invention relates to an engineering surveying instrument, in particular to a laser line marking compensator suitable for measuring horizontal and vertical reference planes and top and ground reference points in engineering and building decoration. Background technique: [0002] At present, in the construction industry, in order to meet the needs of building construction, the horizontal and vertical, as well as the cross and vertical conditions of buildings are often measured or detected, and laser marking instruments are used to obtain horizontal benchmarks, vertical benchmarks, and cross and vertical benchmarks. However, the laser marking instrument currently used has a complex structure, a large volume, is inconvenient to carry, and has a large homing negative difference. And the compensator used in the current similar product structure generally adopts a cylinder. After inserting into the corresponding oblique hole of the cross shaft frame, the...
