Specific embodiment
Fig. 1 is the structural schematic diagram of the laser level of the utility model, a kind of laser level 10, comprising: shell 1,
Bracket 2, pendulum mass 3, main control pcb board 4, alarm assemblies 5, transition pcb board 6, laser source 7, feedback component etc..
As shown in Figs. 1-2, bracket 2 is located inside shell 1, and bracket 2 includes frame upper and bracket lower part；Pendulum mass 3 is installed
In bracket lower part, laser source 7 is housed, laser source 7 is for emitting laser on pendulum mass 3.As in Figure 3-5, pendulum mass 3 passes through as universal
The structures such as connector are dangled in a manner of freely swinging to be hung on bracket 2, and can be swung in a certain range.Main control pcb board 4
Rack-mount portion, for exporting feedback signal；
Alarm assemblies 5, comprising: quoit 51, quoit 51 are mounted on the top of bracket 2, and further, quoit 51 welds
It connects on main control pcb board 4；Quoit 51 is electrically connected with main control pcb board 4；Also there is through hole 52, perforation on quoit 51
Hole 52 is circle；Further, through hole 52 passes through quoit 51 and main control pcb board 4.
Steel wire 53 has one end and free end, and steel wire 53 extends along the direction for being parallel to 3 length of pendulum mass, and wherein one end connects
It is connected on pendulum mass 3, free end passes through the through hole 52 of quoit 51, and further free end passes through quoit 51 and main control
Through hole 52 on pcb board 4；One end of steel wire 53 is electrically connected with transition pcb board 6.Specifically steel wire 53 is connected to transition pcb board
On 6, transition pcb board 6 is fixed on the side of pendulum mass 3, and transition pcb board 6 with main control pcb board 4 by being electrically connected, specifically transition
Pcb board 6 is electrically connected by conducting wire with main control pcb board 4.
When the pendulum mass tilt angle is more than preset range, steel wire 53 is contacted with quoit 51, and quoit 51 passes through steel
Silk 53 is connected with main control pcb board 4 so that main control pcb board 4 exports feedback signal.
Feedback component is for reversed feedback signal and is fed back, and specifically feedback component can be laser source 7, feedback component
It is also possible to individual component, such as buzzer or indicator light.When steel wire 53 and quoit 51 contact, feedback component receives anti-
Feedback signal is lighted with controlling the intermittent flashing of laser source 7 or buzzer call or indicator light.
As shown in figure 5, work as laser level when in the horizontal position, that is, when the laser rays emitted is in a horizontal position, steel
The center location of through hole 52 of the silk 53 in quoit 51, steel wire 53 are not contacted with quoit 51, at this time steel wire 53, quoit
51, main control pcb board 4 does not generate electrical connection, and laser level is not alarmed, and laser level works normally.
As shown in fig. 6-7, when laser level is in obliquity, steel wire 53 is tilted with pendulum mass 3, when pendulum mass 3 inclines
Predetermined position is tiltedly met or exceeded, steel wire 53 touches quoit 51, and steel wire 53, quoit 51, main control pcb board 4 is connected, main
Control pcb board 4 exports feedback signal to feedback component, and feedback component is made to work.Feedback component is used to remind operator, and laser is thrown
Line instrument is in obliquity, adjusts the levelness of laser level.
According to the different inclination alarm angles of setting, the through hole 52 of quoit 51 has various sizes of diameter, this reality
It applies 3 range of tilt angles of pendulum mass in example and is set as 0-5 degree.When pendulum mass 3 is tilted beyond 5 degree, steel wire 53 just can be with quoit 51
Contact.When the inclination of pendulum mass 3 is no more than 5 degree, steel wire 53 is not contacted with quoit 51.
