Description
Technical field
It the utility model is related to survey field, and in particular to one kind is laid flat measurement bar automatically.
Background technology
Various walls, the column of building, are generally required and horizontal plane.It is most of to use three in practical operation
Angle square, but set square structure is single, inconvenient for operation, not only time-consuming but also cumbersome, operating efficiency is low.
The content of the invention
In order to solve the above problems, the utility model provides one kind and is laid flat measurement bar automatically.
The technical solution of the utility model is：One kind is laid flat measurement bar automatically, and cavity, the both sides of cavity are provided with pedestal
Slide rail is provided with, support bar is slidably arranged in cavity, and support bar is connected with horizontally disposed cross bar by axis of rotation, torsion spring
It is set in rotating shaft and is fixedly connected with support bar and cross bar；The both sides of cross bar are articulated with weight, and the weight of both sides is symmetrical on rotating shaft；
Weight head is provided with light source emitter, and the upper surface of weight head is provided with light exit wound of bullet, vertical curve is provided with movement weight rod, erects
Intersect with light exit wound of bullet one end of straight line.
Further, the left and right ends of the cross bar are provided with hook portion, and hook portion phase is provided with the upper-lower position of vertical bar
The snap ring of adaptation.
Further, it is provided with Hygrothermograph on the cross bar.
Further, the cross bar is made up of metal material.
The beneficial effects of the utility model are：The utility model is sent out by the light source emitter of weight from light exit wound of bullet
Go out, light overlaps with vertical curve, in work progress is built, can carry out measuring for verticality, high sensitivity, it is ensured that the standard of detection
True property.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of weight.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, the present embodiment is not formed to this
The limitation of utility model.
As shown in figure 1, a kind of be laid flat measurement bar, including pedestal 1, support bar 2, cross bar 3, rotating shaft 4, torsion spring 5, weight automatically
6th, weight is first 7, light source emitter 8, light exit wound of bullet 9, movement weight rod 10, vertical curve 11, Hygrothermograph 12, hook portion 13, snap ring 14.
Cavity is provided with pedestal 1, the both sides of cavity are provided with slide rail, and support bar 2 is slidably arranged in cavity.Support bar
2 are rotatablely connected with horizontally disposed cross bar 3 by rotating shaft 4, and cross bar 3 is made up of metal material.Torsion spring 5 is set in rotating shaft 4 solid
Determine connection support bar 2 and cross bar 3, when cross bar 3 is partial to side under external force, discharge external force, the screen resilience of torsion spring 5 makes horizontal stroke
Bar 3 is horizontal positioned.The both sides of cross bar 3 are articulated with weight 6, and the weight 6 of both sides is symmetrical on rotating shaft 4.As shown in Fig. 2 weight first 7
Light source emitter 8 is provided with, the upper surface of weight first 7 is provided with light exit wound of bullet 9, vertical curve 11 is provided with movement weight rod 10,
Intersect with light exit wound of bullet 9 one end of vertical curve 11.Light source is sent by light exit wound of bullet 9, light and the weight of vertical curve 11 of both sides
During conjunction, it can detect that cross bar 3 is horizontal positioned.
Hygrothermograph 12 is provided with cross bar 3, while levelness is measured with vertical spend, additionally it is possible to measure humidity and temperature
Degree.
The left and right ends of cross bar 3 are provided with hook portion 13, accordingly, snap ring 14 are provided with the upper-lower position of vertical bar 2, turn
Dynamic cross bar 3, the hook portion 13 of the both sides of cross bar 3 is hung on the snap ring 14 of vertical bar 2, cross bar 3 is placed vertically, and weight 6 turns around axle
Move and be maintained at gravity direction, light source is sent by light exit wound of bullet 9, and engineering construction is carried out by the perpendicularity of light.
It is described above, only it is preferred embodiment of the present utility model, is not used in limitation the utility model, this area skill
Art personnel can make various modifications or equivalent substitution to the utility model in essence of the present utility model and protection domain,
This modification or equivalent substitution also should be regarded as in the protection domain of technical solutions of the utility model.
