2. because the good directionality of laser, monochromatic high brightness characteristic make a kind of easily, visual strong, measure be easy to, Laser plumb that precision is high replaces traditional plummet vertebra point to carry out the Laser plumb of measuring basis location.
3. when measuring, if the laser apparent dip greater than predetermined angle, exceeds the automatic setting range of Laser plumb, laser beam will glimmer, thereby the prompting user of service need readjust or install, and can increase work efficiency greatly like this.
Four, description of drawings:
Fig. 1 is a structural profile synoptic diagram of the present utility model.
Fig. 2 is the utility model battery case polycrystalline substance diagrammatic cross-section.
Five, embodiment
Referring to Fig. 1, Fig. 2, the utility model Laser plumb is made up of the battery case 1 of laying battery and Laser plumb hammer body 2, is connected by locking device 16 with Laser plumb hammer body 2 at battery case 1.Joint 3, circuit board 9, laser module 5, weight 8 and damping spring 10 are installed in the cavity in Laser plumb hammer body 2.Laser module 5 comprises the body 6 and the weight 8 that can send laser beam, and built-in laser instrument 7 is used to send laser beam in the body 6.Weight 8 is located at body 6 belows, is used to produce gravity, makes Laser plumb sagging naturally.Weight 8 belows are provided with magnet steel 20, and magnet steel 20 plays group Buddhist nun effect with weight 8.Inwall at joint 3 is provided with bearing 13, and the top of laser module 5 is provided with joint spider 12, and two axles of joint spider 12 are the body 6 of connection bearing 13 and laser module 5 respectively, thereby enough becomes a gimbal system 11, makes the laser module 5 can free sagging, swing.Be provided with shell 4 in the outside of Laser plumb hammer body 2, with the inner structure of protection Laser plumb hammer body 2.Shell 4 inwalls are provided with damping spring 10 at the relative position of laser module 5, are surrounded on body 6.The control utmost point and the circuit board 9 of damping spring 10 join.The effect of damping spring 10 has 2 points: the one, and damping; The 2nd, as a control utmost point, run into damping spring 10 when laser module 5 swings, laser beam flicker, prompting have surpassed indicating range, its indicating range is by the distance decision between damping spring 10 and the laser module 5, and the distance between damping spring 10 and the laser module 5 can not be zero.Hunting range in the present embodiment is ± 6.。Shell 4 is provided with switch 14; Circuit board 9 is connected with switch 14, joint 3 and damping spring respectively by winding displacement 15.Magnet steel 20 belows are installed cover glass 22 and bottom 24 successively, are used to protect magnet steel 20.Hook 21 also can be established in bottom 24 belows, can not hang a ceiling hammer on hook 21 when Laser plumb has electricity, can be used as common plummet and uses.
Be connected by automatic locking apparatus 16 between battery case 1 and the Laser plumb hammer body 2, guarantee that this Laser plumb in use can be because of battery case 1 and Laser plumb hammer body 2 loosening can't uses.Its concrete structure is: locking device 16 is arranged on the joint 3, comprises spring 17, dog screw 18 and sells 19; Battery case 1 bottom inside is provided with ring groove, and described ring groove below is provided with the perpendicular square groove that joins; Described pin 19, spring 17 are arranged at joint 3 tops, and described pin 19 is connected with spring 17, and described pin 19 is provided with the dog screw 18 with ring groove and square groove clamping.Lay pin 19 at joint 3 middle parts as blind hole, pin 19 is a T type projection.When battery case 1 tightens to the appropriate location downwards in the square groove of pin lug boss jacking battery case 1 under the effect of spring 17 of 19, battery case 1 can't be rotated, play the locking purpose, make the T type projection of pin withdraw from the ring groove of battery case 1 by downside pin 19, battery case 1 is promptly rotatable, reaches the purpose that unlocks.Between battery case 1 and Laser plumb hammer body 2, can establish 0 RunddichtringO 23 and play the water-tight effect.
