Abstract
The utility model relates to a testing instrument which applies a level gauge to measure the inclination. The utility model not only solves the problem of measuring the level as well as the gradient, but also has the advantages of reasonable structure, high precision, accurate readings and convenient carryover. The utility model is characterized in that the utility model uses a common ruler as a ruler body; one end of the ruler seat is hinged with the ruler body by a pin axle, and the other end is connected by a regulating mechanism; the graduated ruler is arranged on the ruler seat and is sheathed in the ruler body, and the scale line and the extension line of the reading indication line both pass through the center of the pin axle connected with the ruler seat and the ruler body. The regulating mechanism is a screw driving pair or a gear pair. The utility model is widely used for detection of the building installation engineering.
Description
The utility model belongs to uses the detecting instrument that level is measured degree of tilt.
The utility model patent (publication number CN2031917U) of horizontal slope device by name is though solved both energy measurement levels, the problem of the energy measurement gradient again, but still have following shortcoming as surveying instrument: (1) blade approaches and grows, on it plane again as the reading reference field must with the rotating shaft center line in same plane, not only manufacture difficulty is big for this, and yielding, precision is low.(2) regulate nothing connection or locking device between bolt one end-apparatus seat and the blade, cause reading inaccurate easily, when being used as guiding ruler, particularly evident.(3) graduated scale exposes, and breaks easily, and the scale mark direction does not have strict demand, and precision is low.
The purpose of this utility model provides a kind of rational in infrastructure, precision height, accuracy of reading, horizontal slope chi easy to carry.
Technical solution of the present utility model is as follows.The horizontal slope chi is made up of rod support, blade and two to three levels, one end of rod support and blade is hinged with bearing pin, the other end of rod support is provided with rule and governor motion, the other end of rod support and blade is connected with governor motion, there is rule to be enclosed within the blade on the rod support, have the reading hole on the blade, a side relative with the scale mark outward flange in the reading hole is carved with the reading index line, and the extended line of scale mark and reading index line is all by being connected the bearing pin center line of rod support and blade.
Governor motion can be worm drive pair (A type chi), and screw axial is fixed on the blade, and the vertical section of nut is contained in the slotted hole of rod support for circular, both can rotate in slotted hole, again slidably.
Governor motion also can be gear pair (Type B chi), and gear shaft is connected with blade, and sector gear is arranged on the rod support, and relative clamping screw between blade and rod support can be housed.
The reading hole can be opened on the cover board, and cover plate is fastened on the blade.
The utility model compare with original technology have rational in infrastructure, precision is high, the advantage of accuracy of reading.Simultaneously easy to carry, the life-span is long.

Fig. 2 is the utility model Type B chi synoptic diagram.
Fig. 3 is an A type chi governor motion partial enlarged drawing.
Fig. 4 is a Type B chi governor motion partial enlarged drawing.
Fig. 5 is the B-B cut-open view of Fig. 3.
Now in conjunction with the accompanying drawings the utility model specific embodiment is described as follows:
As Fig. 1, Fig. 2, shown in Figure 3, the horizontal slope chi is made up of rod support (4), blade (3) and level (1), (5), (10).Rod support (4) section Wei Shang shape, an end has rule (7).Blade (3) is the light water leveling ruler, above in the middle of level (5) is housed, both sides are equipped with level (1) and (10) respectively, the bottom section is
Shape, (4) De Shang shapes are relative with rod support.One end of blade (3) is hinged with bearing pin (2) and rod support (4), and the other end has the hole, and the rule (7) on the rod support (4) is enclosed within the hole, and reading cover plate (6) links to each other with blade (3) with screw (13).Be carved with reading index line (17) on the reading cover plate (6).The extended line of scale mark and reading index line is the center by bearing pin (2) all.The centre distance scale mark outward flange 500mm of bearing pin (2), the scale wire spacing is 0.5mm, the indicated value of slope of its every lattice is a per mille.
As Fig. 3, shown in Figure 5, the governor motion of A type chi is the worm drive pairs.Screw rod (16) is fixedlyed connected with handwheel (8), screw rod (16) is connected with blade (3) with set nut (9) with back-up ring (20), the vertical section of nut (15) is circular, be contained in the slotted hole (14) of rod support (4), when screw rod (16) rotates, nut (15) both can rotate in slotted hole (14), again slidably.During measurement rod support (4) is abutted against on the object being measured, rotary screw (16), nut (15) is constant with rod support (4) bottom surface distance, screw rod (16) promptly drives blade (3), rotate around bearing pin (2), treat level (5) when steam bubble is placed in the middle, indicated numerical value is the gradient of this measured object on the rule.When doing the guiding ruler use, operation and principle are identical, just the level difference of observing.
As shown in Figure 4, the governor motion of Type B chi is a gear pair, and sector gear (18) is an one with rule (7), and gear shaft (19) one ends are installed on the blade (3); The other end is installed on the reading cover plate (6), and spindle nose is fixedlyed connected with turn-knob (11).Rotate turn-knob (11) during measurement, gear shaft (19) just drives blade (3) and rotates around bearing pin (2), gets final product reading when observed level steam bubble is placed in the middle.For accuracy of reading is provided with clamping screw (12), with the relative locking of rod support (4) with blade (3).
The rod support of this horizontal slope chi and blade material are cast aluminium or cast iron.
