For achieving the above object, the technical scheme that the present invention takes is: a kind of suspender of laser measuring apparatus, it comprises the laser projections module, pedestal and frame body, wherein said laser projections module is installed on the frame body, described frame body is installed on the pedestal, the laser projections module is provided with a pair of first back shaft, described frame body is provided with the clutch shaft bearing that cooperates with first back shaft, frame body is provided with a pair of second back shaft along the direction vertical with first back shaft, frame body is provided with second bearing that cooperates with second back shaft, described first back shaft is vertical mutually with second back shaft, be provided with a magnet in base bottom, when described weight rocked, described magnet can adsorb weight.
The suspender of laser measuring apparatus of the present invention further is set to: described frame body comprises a main part and is immobilizated in the first gland portion on the main part that the main part and the first gland portion form the accepting hole of accommodating clutch shaft bearing.
The suspender of laser measuring apparatus of the present invention further is set to: the described first gland portion is installed on the main part by a pair of screw.
The suspender of laser measuring apparatus of the present invention further is set to: the main part of described frame body is circular, and the laser projections module is positioned at circular main part centre position.
The suspender of laser measuring apparatus of the present invention further is set to: described pedestal comprises two hold-down arms that be arranged in parallel mutually and is immobilizated in the second gland portion on the hold-down arm that the hold-down arm and the second gland portion form the accepting hole of accommodating second bearing.
The suspender of laser measuring apparatus of the present invention can also be set to: the described second gland portion is installed on the hold-down arm by a pair of screw.
Compared with prior art, the present invention has following beneficial effect: first back shaft of described laser projections module cooperates with the clutch shaft bearing of frame body can make the laser projections module swing, second back shaft of frame body cooperates with second bearing of pedestal can make the swing of laser projections module, simultaneously, the magnet of base bottom can adsorb weight, increased the sagging power of laser projections module, thereby make laser measuring apparatus penetrate the smooth and easy swing of module energy, measuring basis is more accurate, has improved the quality of product.In addition, gland portion installs by screw, makes assembly and disassembly convenient, and simple in structure.
[description of drawings]
Fig. 1 is the stereographic map of the suspender of laser measuring apparatus of the present invention.
Fig. 2 is the three-dimensional exploded view of the suspender of laser measuring apparatus of the present invention.
[embodiment]
See also Fig. 1 to shown in Figure 2, the present invention is a kind of suspender of laser measuring apparatus, and it comprises laser projections module 1, pedestal 2 and frame body 3.Wherein said laser projections module 1 is installed on the frame body 3, and it can produce laser beam and to projection all around, to being provided with a pair of first back shaft 11, the bottom that is positioned at this laser projections module 1 also is provided with a weight 12 in these laser projections module 1 front and back.Described frame body 3 is installed on the pedestal 2, it is circular, laser projections module 1 is positioned at the centre position of annular frame body 3, this frame body 3 comprises a main part 31 and is immobilizated in the first gland portion 32 on the main part, the main part 31 and the first gland portion 32 install mutual fixing and form the accepting hole 34 of accommodating a clutch shaft bearing 4 by a pair of screw 6, described first back shaft 11 matches with clutch shaft bearing 4, thereby make laser projections module 1 can along about to rocking, be provided with a pair of second back shaft 35 in this frame body 3 along the direction vertical with first back shaft 11.Described pedestal 2 comprises a pair of hold-down arm that is arranged in parallel 21 and is immobilizated in the second gland portion 22 on the hold-down arm 21, this second gland portion 22 is installed on the main part 31 by a pair of screw 6 and forms the accepting hole 23 of accommodating second bearing 5, described second back shaft 34 matches with second bearing 5, thereby makes the laser projections module 1 can be along front and back to rocking.Also be provided with the magnet 8 of the weight that can adsorb the laser projections module in pedestal 2 bottoms.Described magnet can produce permanent magnetic field, when laser projection device drive weight rocks, the magnetic induction line that described weight 12 energy septum magnets 8 produce, because electromagnetic induction principle, also can produce inductive electromagnetic on the described weight 12, and direction is opposite with magnet magnetic induction line direction, thereby magnet 8 and weight 12 are adsorbed mutually, increased the sagging power of laser projections module 1, made laser projection device static fast.
