Specific embodiment 1: as shown in Fig. 1 ~ Fig. 5, the invention discloses a kind of construction account verticality detection tool,
Including hand-held support, detection components and angle scale 10, the hand-held support includes T shape strut 1, handle 2, platform board 4 and three
Root feeler lever 3,1 one side surface of T shape strut is respectively perpendicular adjacent to three free end positions is fixed with a feeler lever 3, and described three
Root feeler lever 3 it is isometric setting and every 3 outer end of feeler lever be made as spherical surface, the handle 2 is fixed in another side surface of T shape strut 1
Between position, the platform board 4 is horizontally fixed between two feeler levers 3 being located above, and platform boards 4 are protruded in two 3 outer ends of feeler lever
Corresponding end surface, it includes cylinder that 4 center of platform board, which vertically offers circular hole 4-1 to install detection components, the detection components,
Shape shell 5, suspension plectane 6,7, two ring sealing plates 8 of upright bar and two sealing films 9, the cylindrical case 5 are vertically fixed on institute
It states in circular hole 4-1, the fitting of 5 inner sidewall of cylindrical case is fixed with outer ring magnet, and the suspension plectane 6 is coaxially located at cylindrical case 5
Interior, the fitting of 6 circumferential position of suspension plectane is fixed with interior ring magnet, the interior ring magnet excircle and the outer ring magnet inner periphery
Interval setting and homopolar-repulsion, described two 8 excircles of ring sealing plate seal with 5 upper and lower ends of cylindrical case fix respectively,
7 middle position of upright bar and the centre bore that suspension plectane 6 opens up are coaxially affixed, and described two sealing films 9 enclose respectively to be set as leaking
It is bucket-shaped to be sealed closing between two 8 inner peripherys of ring sealing plate and upright bar 7, each 9 big opening end of sealing film and corresponding ring
The sealing of 8 inner periphery of shape sealing plate is viscous fixed, and each 9 osculum end of sealing film and the sealing of 7 corresponding position of upright bar are viscous fixed, seals 9 interposition of film
Loose setting is set, does not influence the vertical state of upright bar 7, there is perfusion liquid 11 in cylindrical case 5,7 upper end of upright bar is fixed with pointer 7-
1,7 lower end of upright bar is fixed with weighted spherical ball 7-2, and the submergence of suspension plectane 6 is suspended in the perfusion liquid 11, and the angle scale 10 is installed
It is equipped on T shape strut 1 and with the pointer 7-1, angle scale 10 is equipped with vertical cut-off rule.
Specific embodiment 2: as shown in Fig. 2, present embodiment is made furtherly to specific embodiment one
Bright, 10 bottom of angle scale is equipped with slide 10-1, and the slide 10-1 is integrally formed with plectrum, the 1 upper surface water of T shape strut
Flat to be equipped with slideway 1-1, angle scale 10 is slidably arranged on the slideway 1-1 by slide 10-1.
