Abstract
The utility model relates to a gradient-measuring level. The utility model has the technical proposal characteristics that the utility model also comprises an auxiliary ruler, and a main ruler is hinged with the auxiliary ruler at the bottom. On the main ruler, the outer ring of a hinge axis is provided with an angle graduated disk, and a hinge axis of the auxiliary ruler is provided with an angle pointer. The upper part of the auxiliary ruler is provided with a draw rod, and the main ruler is provided with a hole for the draw rod. When the auxiliary ruler is pulled out, the draw rod needs to be inserted into the hole for the draw rod. On the main rule, the position of the hole for the draw rod is provided with a jack screw which is used for fixing the draw rod. Compared with the prior art, the utility model not only can measure the horizon and verticality, but also can measure the gradient. The gradient measurement is fast and accurate.
Description
The utility model relates to a kind of spirit-leveling instrument.
Surveyor's staff is the indispensable instrument of construction account, building operation, and two bubbles are arranged on it, and one is horizontal level, another vertical level, and obviously it can only survey level with vertical, can not survey slope (or tiltedly) degree.
The purpose of this utility model provides a kind of spirit-leveling instrument that can survey the gradient.
The purpose of this utility model is achieved in that on horizontal main scale, increases a secondary chi, and major and minor chi is in its bottom-hinged, on main scale, there is angle dial the outer ring of hinge axis, on the hinge axis of secondary chi angle indicator is arranged, and on the top of secondary chi pull bar is arranged, tie rod hole is arranged on main scale, when drawing back secondary chi, pull bar need be inserted in the tie rod hole, on main scale, on the position of tie rod hole jackscrew is arranged, be used for fixing pull bar.Using method is: when the survey level or when vertical, with horizontal bubble on the main scale or vertical bubble, when survey the gradient (or) during gradient, secondary chi is drawn back, and pull bar inserts in the tie rod hole, and main scale keeps vertical (or level), when secondary chi is consistent with measured object, with jackscrew pull bar is fixed, the gradient (or gradient) of this moment is exactly an angle between major and minor two chis, can read by angle scale.
The utility model is compared with existing level chi technology, not only can survey level or vertical, can also the deviational survey degree, and quick when deviational survey is spent, accurately.
Below in conjunction with accompanying drawing the utility model is done a step explanation.
Accompanying drawing is a structural representation of the present utility model.
Horizontal bubble 1 and vertical bubble 3 are arranged on the horizontal main scale 2, be respectively applied for the measurement level with vertical, feature of the present utility model is: it also has a secondary chi 5, major and minor chi is in its bottom-hinged 7, and on main scale, there is angle scale 8 outer ring of hinge axis 7, angle indicator 6 is arranged on the hinge axis of secondary chi, on the top of secondary chi pull bar 4 is arranged, tie rod hole 9 is arranged on main scale, when drawing back secondary chi, need pull bar is inserted in the tie rod hole, on main scale, jackscrew 10 is arranged on the position of tie rod hole, be used for fixing pull bar.Using method is: when the survey level or when vertical, with horizontal bubble on the main scale or vertical bubble, when survey the gradient (or) during gradient, secondary chi is drawn back, and pull bar inserts in the tie rod hole, and main scale keeps vertical (or level), when secondary chi is consistent with measured object, with jackscrew pull bar is fixed, the gradient (or gradient) of this moment is exactly an angle between major and minor two chis, can read by angle scale.
Claims (1)
1, a kind of spirit-leveling instrument that can survey the gradient has main scale, and horizontal bubble and vertical bubble are arranged on it, it is characterized in that: further comprising secondary chi, major and minor chi is in its bottom-hinged, on main scale, there is angle dial the outer ring of hinge axis, on the hinge axis of secondary chi, angle indicator is arranged, pull bar is arranged, tie rod hole is arranged on main scale on the top of secondary chi, when drawing back secondary chi, pull bar need be inserted in the tie rod hole, on main scale, on the position of tie rod hole jackscrew be arranged.
