Description
Technical field
The present invention relates to a kind of laser level more particularly to a kind of swashing with the warning device for detecting fuselage gradient
Light level.
Background technique
Laser level is widely applied in the fields such as architectural engineering, house decoration at present.Self-balancing type level can
There is provided automatic horizontal, vertical laser line of reference and be widely used.Self-balancing type level is divided into mechanical self-balancing and electronics certainly
Two kinds of balance.In mechanical self-balancing, using a pendulum, balance and stability is achieved the effect that by the gravity of pendulum itself.Pendulum
Hammering into shape itself has the range that freely swings, about at -5 ° to+5 °.When the placement angle of laser level goes beyond the scope, pendulum mass
Normal vertical state will no longer be reached, self-balancing system cannot reach self-balancing effect at this time, at this moment just body be needed to issue
Alarm reminds user to ajust level.
The alarm system of existing laser level is usually using mechanical：A kind of sheet metal being fixed on pendulum mass
Carry out detection alarm with fixed spring on circuit boards, when pendulum mass swing angle goes beyond the scope, sheet metal on pendulum mass and
Spring interface touching on circuit board, circuit conducting generate electric signal, alarm equipment alarm；It is under pendulum mass there are also a kind of mode
It holds pendulum periphery to use conductive rubber, metal ring is set on base internal wall, when pendulum mass swing goes beyond the scope, conductive rubber
It is contacted with metal ring, generates electric signal, alarm equipment alarm.Above two warning device mechanically generates electric signal
It alarms, relative complex in structure, precision is not high.
For example utility model CN204854737U discloses a kind of gravity pendulum laser line-cast instrument, which uses magnetic
The magnetic damping device of steel seat, damping fin and alarm circle composition controls pendulum hunting range, but equally exists above-mentioned mechanical alarm side
Structure is complicated for formula, the not high problem of precision；Utility model CN204831298U uses the side of installation alarm board on the outside of pendulum mass
Formula still falls within mechanical system alarm although overall structure is more compact, and measurement accuracy inclined for pendulum mass is not equally high；
Utility model patent CN206323510U discloses a kind of dress that can detecte laser level plummet precision, horizontal accuracy etc.
It sets, and includes the rack for installation detecting device, but the device structure is huge numerous and jumbled, is not suitable for making in small space
With excessively complicated structure is also unfavorable for daily maintenance；Patent of invention CN103712633B discloses a kind of laser level light
Laser beam position feedback is controlled servo electricity to industrial computer by linear CCD sensor by the method for line Self-regulation track
Machine drives spanner to adjust and swings the swing that bolt realizes laser bench, but due to equipped with multiple servo motors and complicated route knot
Structure, it is with high costs, it is unfavorable for marketing；Patent of invention CN104515512A discloses a kind of square laser level, though
So its is compact-sized, changes laser projection convenient for rotation and puts direction, but its do not have pendulum mass tilt angle it is excessive when alarm
Function.
In consideration of it, how to design a kind of precision is higher than tradition machinery formula laser level, but retains again mechanical swash simultaneously
The level of the simply small and exquisite advantage of light level structure, and there is gradient over range warning function, it is that this field is urgently to be resolved
A project.
Summary of the invention
The present invention provides a kind of laser level, including chassis bracket, pendulum, further includes warning device, wherein the report
Alarm device includes angular transducer and warning circuit, and the angular transducer is connected with the warning circuit, is fixed on the machine
On shell bracket, the warning circuit receives the angle of the angular transducer measurement, when the angle is greater than the set value alarm.
Further, 5 ° be the angle ranging from, when pendulum swing angle is more than -5 ° or+5 °, warning circuit alarm.
Further, angular transducer is acceleration transducer or one of gyro sensor or obliquity sensor.
The present invention can simply, fast and accurately detect the gradient of level fuselage, to the off-limits situation of angle
It alarms.

Specific embodiment
The specific embodiment that the invention will now be described in detail with reference to the accompanying drawings.In the explanation of following specific embodiments, in order to
Clearly show that structure and working method of the invention, will be described by many Directional words, but should by " preceding ",
The Word Understandings such as " rear ", "left", "right", "outside", "inner", " outside ", " inside ", " axial direction ", " radial direction " for convenience of term, without
It should be understood as word of limitation.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to
Limit the present invention.
Fig. 1 is the structural schematic diagram with the laser level of warning device.The level includes chassis bracket 1, fixed
Bracket 2, pendulum 3, cross axle 4, feature board 5, mode of laser group, 6, Laser Driven plate 7, power panel 8 and angular transducer 9.Figure
Shown in level use mechanical self-balancing approach, pendulum 3 is mounted on fixed bracket 2 by cross axle 4, fixed bracket 2
It is locked on chassis bracket 1, mode of laser group 6 is mounted in pendulum 3, connects Laser Driven plate 7, Laser Driven plate 7 and feature board
5, power panel 8 is connected, and feature board 5 and power panel 8 are each attached on chassis bracket 1, the setting of angular transducer 9 in feature board 5 or
On power panel 8, it is connected with warning circuit.
With putting for machine, pendulum 3 is swung, and reaches stable state by self gravity.When being well placed machine, angle sensor
Device 9 can measure the gradient that machine is put at this time, send warning circuit to, when measured angle is greater than the angle of setting
When, warning circuit alarm.
Angular transducer 9 can be acceleration transducer, gyro sensor or obliquity sensor.Angular transducer measurement
Angle precision be higher than mechanical structure, and the speed of angular transducer measurement is fast, does not need the cooperation of corresponding structure, machine
Structure is relatively easy, and simple alignment is only needed in production technology, does not need to carry out complicated debugging, convenient for production quick.
