Detailed description of preferred embodiment
Referring now to Fig. 1, the figure shows one according to a preferred embodiment of the invention structure do and the level meter 10 of operation.Level meter 10 preferably includes a main body 12, and this main body has a surface level 14, is used to measure a surface 16.Main body 12 is preferably made by the metal alloy with mechanical stability and wearing quality, and is such just as is known in the art.Surface level 14 has highly accurate flatness and smoothness usually.End cap 18 is made of plastics usually, the two ends of being fixed in main body 12 like that it can road as known in the art.
According to a preferred embodiment of the invention, an optics conveying element 30 is fixed on the main body 12, and this element is sent to the image of bubbler tube 20 on roughly parallel with measured surface 16 inspection surface 32.As shown in Figure 1, optics conveying element 30 preferably includes a reflecting surface 36, and this face is installed in the inside of a hollow space of main body 12, with bubbler tube 20 and inspection surface 32 at angle, this reflecting surface 36 with the image reflection of bubbler tube 20 to inspection surface 32.Reflecting surface 36 can be a for example polishing mirror or a prism.Best, on surface 34, cut out a window 38, thereby user 40 can observe the image of bubbler tube 20 on the inspection surface 32 easily.
Referring now to Fig. 2, the figure shows level meter 10 and tilt with an angle [alpha] with respect to tested vertical surface 16.On the direction of Fig. 2, as can be seen the lower limb of level meter 10 is moved apart surface 16 and make bubble 42 move, thereby the image of bubble 42 moves up on inspection surface 32 as can be seen towards user 40.This is because optics conveying element 30 on the direction of Fig. 2, is positioned on the bubbler tube 20.Should be understood that the coboundary that makes level meter 10 on the contrary moves apart surface 16 bubble 42 is moved away from user 40, thereby the image that can see bubble 42 moves down on inspection surface 32.
Referring now to Fig. 3, the figure shows that structure is according to another preferred embodiment of the invention done and the level meter 50 of operation.Level meter 50 is roughly the same with level meter 10, therefore components identical is adopted identical label.The difference of level meter 50 and level meter 10 be optics conveying element 52 be installed in bubbler tube 20 below, the importance of this variation is described with reference to Fig. 4.
Referring now to Fig. 4, the figure shows level meter 50 with respect to angle beta of tested vertical surface 16 inclinations.On the direction of Fig. 4, the lower limb of level meter 50 makes bubble 42 move towards user 40 away from the inclination on surface 16 as can be seen, thereby the image of visible bubble in bubble 42 moves down on inspection surface 32.This is because optics conveying element 52 is positioned at below the bubbler tube 20 on the direction of Fig. 4.On the contrary, when the coboundary that can know level meter 52 tilted away from surface 16, bubble 42 can move towards the direction away from user 40, thereby the image of bubble 42 on inspection surface 32 moved up.
Referring now to Fig. 5, the figure shows that structure is according to another preferred embodiment of the invention done and the part of the level meter 60 of operation.Level meter 60 is roughly the same with level meter 10, therefore components identical is adopted identical label.The difference of level meter 60 and level meter 10 is the image of set optics conveying element 62 scalable bubbler tubes 20.This can realize by for example in the centre of reflecting surface 36 and inspection surface 32 amplifying lens 64 being set.Lighting device 66 can be set, and for example electric light or light emitting diode (LED) are used for illuminating the image of bubbler tube 20.
Referring now to Fig. 6, the figure shows a part according to the level meter 70 of another preferred embodiment structure work according to the present invention and operation.Level meter 70 is roughly the same with level meter 10, therefore components identical is adopted identical label.Level meter 70 is that with the difference of level meter 10 set optics conveying element 72 can reduce the picture size of bubbler tube 20.This can realize by for example in the centre of reflecting surface 36 and inspection surface 32 reducing glass 74 being set.
Referring now to Fig. 7, the figure shows a part according to the level meter 80 of work of a preferred embodiment structure more of the present invention and operation.Level meter 80 is roughly the same with level meter 10, therefore components identical is adopted identical label.Level meter 80 is optics conveying element 82 by an electronic observation device 86 with the difference of level meter 10, and microcam for example is sent to the image of bubbler tube 20 on the screen 84, LCDs (LCD) for example, and this screen is positioned on the inspection surface 32.Optics conveying element 82 is without any need for reflecting surface.
Referring now to Fig. 8, the figure shows a part according to the level meter 90 of another preferred embodiment structure work according to the present invention and operation.Level meter 90 is roughly the same with level meter 10, therefore components identical is adopted identical label.Level meter 90 is that with the difference of level meter 10 set optics conveying element 92 is installed in the outside of level meter 90.Optics conveying element 92 preferably includes a reflecting surface 94, for example a mirror or prism, and to an inspection surface 96, this inspection surface is roughly parallel to measured surface 16 to this reflecting surface with the image reflection of bubbler tube 20.Reflecting surface 94 preferably can disassemble from level meter 90, and can be hinged with level meter 90 by a hinge 98.Therefore, optics conveying element 92 can be used as the circumscribed annex of level meter 90.
Optics conveying element 92 can have refractive power.For example, optics conveying element 92 can be curved surface, thereby the image of bubbler tube 20 is amplified or distortion.Optics conveying element 92 also can rotate around an axis 99 of bubbler tube 20.
Those skilled in the art will appreciate that the present invention not only be confined to above shown in described embodiment.And scope of the present invention also comprises above-mentioned combination of features and distortion, and their correction and variation, and these all are that those skilled in the art are obtainable by reading top description, and these features all are not included in the prior art.
