Abstract

The utility model relates to a spirit level which uses a semicircular or arcuate weight dropper which can rotate around the fulcrum shaft of the spirit level as the level gauge. The levelness is indicated through a gear wheel and an indicating needle. The utility model has the advantages that the manufacturing technique of the level gauge is simple, and the levelness and the verticality can be measured with the same spirit level.

Description

Level-meter

The utility model relates to a kind of level meter, is used to measure levelness, degree of tilt or the verticality of point-to-point transmission.

Known level meter is made up of framework and the level, the scale that are contained on the framework.Its level is one and is filled with liquid but has the curved glass pipe of air gap.For example frame level on the market and Woodworker leveler come to this.The shortcoming of this level meter is a level manufacturing process complexity, and reading is directly perceived inadequately, and can only do low-angle measurement.

The purpose of this utility model provides a kind of level meter, and its level manufacturing process is simple, reading is directly perceived, and can do the arbitrarily angled measurement from the level to the vertical.

Task of the present utility model realizes with following method: the level with the half garden shape that can rotate around its fulcrum or arc weight are made level meter is fixed with a gear, this gear and the pinion that is contained on the framework on weight.Pointer is housed on the pinion wheel, corresponding scale is arranged on the framework.

The utility model has the advantages that its level manufacturing process is simple, directly perceived with pointer indication reading, can measure at any angle.

The utility model will be further described below in conjunction with accompanying drawing:

(1) is that framework, (2) are that index dial, (3) are that pointer, (4) are that pinion wheel, (6) are that arc weight, (7) are that weight fulcrum, (5) are that gear, (8 of being fixed on the weight) are bottom lines as shown in the figure.

Because the imaginary on line at the center of gravity of arc weight (6) and the center of fulcrum (7) keeps vertical under the weight effect, the variable angle of the bottom line (8) of this root pedal line and framework (1) can make the pinion wheel (4) that is installed on the framework turn over corresponding angle by the gear (5) that is fixed on the weight (6).Pinion wheel (4) just drives fixed thereon pointer (3) thereby makes corresponding corner and can read visual indication on index dial.Gear (5) the employing gear wheel that is fixed on the weight (6) is to make convenient reading directly perceived for the minute angle that makes bottom line (8) changes the corner that pointer (3) is made greatly.When increasing measuring accuracy, can adopt by needs the engagement of multiple sets of teeth wheel.

Semicircle or arc weight (6) can adopt flake structure, makes of process for stamping, and manufacturing process is simple, measures verticality, degree of tilt or levelness, and is available same as level meter, only needs to mark corresponding scale on index dial and gets final product.

Claims (2)

1, a kind of level meter, form by framework and the level, the scale that are contained on the framework, it is characterized in that: level [6] is can be around the semicircle or arc weight of its fulcrum [7] rotation, be fixed with gear [5] on the level, gear [5] and pinion wheel [4] engagement that is contained on the framework are equipped with pointer [3] on the pinion wheel [4].

2, level meter according to claim 1 is characterized in that: the semicircle or arc weight (6) of forming level is with metal.
