Description
Technical field
The utility model relates to a kind of portable unit, is specifically related to a kind of portable laser large wall plastering flatness testing fixture.
Background technology
In construction work, large wall plastering surface evenness and common degree of plainness for wall surface generally adopt guiding ruler or clearance gauge to measure inspection, but the measuring point that check result is often chosen with survey crew and guiding ruler arrangement method have close relationship, inspection of plastering for large area metope often cannot check and put in place, and easily occurs error.
Utility model content
Utility model object: the utility model object is for the deficiencies in the prior art, provides a kind of portable laser large wall plastering flatness testing fixture.
Technical scheme: portable laser described in the utility model large wall plastering flatness testing fixture, comprise master and hold bar, connecting link and laser beam emitting device, described master holds the two ends that bar and laser beam emitting device are individually fixed in described connecting link, and the light source line of described laser beam emitting device holds rod axis perpendicular to described master; Described master holds bar and is made up of laminating section and glissile segment successively, and described connecting link can move radially and/or axial-rotation along described glissile segment, and described laminating section has right angle groove in the axial direction.
Preferably, described connecting link comprises the first anchor ear, linkage section and the second anchor ear, and described first anchor ear and described second anchor ear are fixed on described linkage section both sides, described first anchor ear axis and described second anchor ear axes normal.
Preferably, inside described first anchor ear, be provided with rubbing surface, guarantee that described first anchor ear and described glissile segment surface of contact have certain tautness.
Preferably, described glissile segment is provided with scale area, is convenient to connecting link and moves axially accurately on the main glissile segment holding bar according to error permissible value of plastering.
Compared with prior art, its beneficial effect is the utility model: the utility model volume is little, draw materials simple, makes and easy to carry, can fast and convenient inspection wall plastering flatness, and flatness Checking on effect is directly perceived, and degree of accuracy is higher.Special in large span wall plastering flatness, it is convenient to check.

Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1: a kind of portable laser large wall plastering flatness testing fixture, comprise master and hold bar 1, connecting link 2 and laser beam emitting device 3, main hold the two ends that bar 1 and laser beam emitting device 3 are individually fixed in connecting link 2, and the light source line of laser beam emitting device 3 holds bar 1 axis perpendicular to main; The main bar 1 that holds is made up of laminating section 12 and glissile segment successively, and connecting link 2 moves radially and/or axial-rotation along glissile segment, can detect the flatness of whole metope, and laminating section 12 is provided with right angle groove in the axial direction, is close to body of wall corner.
Wherein: connecting link 2 is made up of the first anchor ear 21, linkage section 22 and the second anchor ear 23, the first anchor ear 21 and the second anchor ear 23 are fixed on linkage section 22 two ends, the first anchor ear 21 axis and the second anchor ear 23 axes normal.
Be provided with rubbing surface inside first anchor ear 21, guarantee that the first anchor ear 21 and glissile segment surface of contact have certain tautness.
Glissile segment is provided with scale area 11, and connecting link 2 can move axially on the main glissile segment holding bar 1 accurately according to error permissible value of plastering.
Comprise during concrete use as under type:
A) right angle groove in laminating section 12 is close to body of wall corner, is plastering within the scope of error permissible value, regulating position and the angle of connecting link 2 according to the scale area 11 on glissile segment.
B) open laser beam emitting device 3, if wall plastering is within the scope of error permissible value, laser spots will be projeced into other metopes of metope end or occur without incident point on examined metope; If wall plastering exceeds error permissible value, laser spots will be incident upon on the metope of protrusion; If metope depression exceedes permissible value, laser beam will become greatly, easily by naked eyes identification with metope spacing.
C) after finishing using, laser beam emitting device 3 is closed, take off portable laser large wall plastering flatness testing fixture.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
