Abstract

The utility model provides a laser and bubble combined level gauge which relates to a surveying and mapping instrument and is characterized in that: the laser and bubble combined level gauge is provided with a base, 3 to 4 adjusting bolts are uniformly distributed on the upper circular disc surface of the base, an adjusting disc is placed on the adjusting bolts, a bubble leveling pipe is embedded on the adjusting disc, the adjusting disc is provided with an upward center shaft, a rotating bearing is sheathed on the center shaft, and a laser beam transmitting device is fixed on the rotating bearing. With reasonable structure, the laser and bubble combined level gauge realizes convenient and accurate level measuring in places with poor light.

Description

Laser, bubble combined horizontal instrument

(1) technical field: the utility model relates to instrument of surveying and mapping, particularly a kind of laser, bubble combined horizontal instrument.

(2) background technology: at present, what measurement levels such as building operation, timber work were used is air-bubble level, needs the naked-eye observation bubble position, and overcast and rainy or that light is bad is indoor, then is difficult for seeing clearly, very inconvenience, and very easily cause error.

(3) summary of the invention: the purpose of this utility model will address the above problem exactly, and a kind of laser in overcast and rainy or the indoor also measurement level accurately and easily that light is bad, bubble combined horizontal instrument are provided.

Concrete scheme of the present utility model is: laser, bubble combined horizontal instrument, it is characterized in that: have an I-shaped base, disc face is evenly equipped with 3-4 and regulates bolt on the base, be shelved with an adjustment disk on it, be embedded with the bubble level pipe on the described adjustment disk, and have a central shaft that makes progress, be set with a rolling bearing on the described central shaft, be fixed with a laser beam emitter on the rolling bearing.

Described base is right cylinder, cube, the I-shaped or support rack type base of upper and lower surfacing.

1 circular bubble level pipe of setting-in or 2 cylindrical bubble level pipes on the described adjustment disk, when the cylindrical bubble level pipe of 2 of setting-ins, 2 cylindrical bubble level pipes are that mid point is 90 degree and arranges with the adjustment disk center, to guarantee the levelness of adjustment disk.

Described laser beam emitter has gauge tap, and is fixed with a circle or cylindrical bubble level pipe on the laser beam emitter, with the levelness that guarantees that the laser beam emitter is given off laser beam.

The spot radius that described laser beam emitter is launched is 0.5-1.0mm, with the degree of accuracy of controlling level point.

The utility model is rational in infrastructure, by the level of bubble level pipe adjusting self, utilizes the directed luminous performance characteristic of laser beam, and having realized also can the very convenient levelness of measuring measured target exactly in the bad place of light.

Fig. 1 is the main apparent direction structural representation of one of the utility model structure;

Fig. 2 is that one of the utility model structure is overlooked the direction structure synoptic diagram;

Fig. 3 is two main apparent direction structural representations of the utility model structure;

Fig. 4 is that two of the utility model structure is overlooked the direction structure synoptic diagram.

Among the figure: the 1-base, 2-regulates bolt, 3-adjustment disk, 4,5, the cylindrical bubble level pipe of 10-, 6-central shaft, 7-rolling bearing, 8-laser beam emitter, 9-switch, 11, the circular bubble level pipe of 12-.

(5) embodiment:

Embodiment 1: referring to Fig. 1, Fig. 2, the utlity model has an I-shaped base 1, disc face is evenly equipped with 4 and regulates bolt 2 (not completely shown among the figure) on the base 1, be shelved with an adjustment disk 3 on it, being embedded with on the described adjustment disk 3 with adjustment disk 3 centers is that mid point is two cylindrical bubble level pipes 4 of 90 degree layouts, 5, and has a central shaft that makes progress 6, be set with a rolling bearing 7 on the described central shaft 6, be fixed with a laser beam emitter 8 on the rolling bearing 7 with gauge tap 9, the spot radius that laser beam emitter 8 is launched is 1.0mm, also be fixed with a cylindrical bubble level pipe 10 on the laser beam emitter 8, promptly constitute the utility model.

Embodiment 2: referring to Fig. 3, Fig. 4, the utlity model has a support rack type base 1, disc face is evenly equipped with 3 and regulates bolt 2 on the base 1, be shelved with an adjustment disk 3 on it, be embedded with 1 circular bubble level pipe 11 on the described adjustment disk 3, and has a central shaft that makes progress 6, be set with a rolling bearing 7 on the described central shaft 6, be fixed with a laser beam emitter 8 on the rolling bearing 7 with gauge tap 9, the spot radius that laser beam emitter 8 is launched is 0.5mm, also be fixed with a circular bubble level pipe 12 on the laser beam emitter 8, promptly constitute the utility model.

The installation of the present utility model and the course of work:

1. adjustment disk 3 is shelved on the base 1 (firm for making it, the position of the adjusting bolt 2 on the corresponding base 1 of trying to get to the heart of a matter makes suitably depression in advance), 2 cylindrical bubble level pipes 4,5 (or circular bubble level pipe 11) on the observation adjustment disk 3, regulate the adjusting bolt 2 on the base 1, make the bubble in the cylindrical bubble level pipe 4,5 (or circular bubble level pipe) all be in the horizontal tube center, even adjustment disk 3 is parallel to the earth;

2. rolling bearing 7 is sleeved on the central shaft 6 on the adjustment disk 3;

3. observe the bubble in the cylindrical bubble level pipe 10 (or circular bubble level pipe 12), the levelness of further regulating rolling bearing 7 and laser beam emitter;

4. open gauge tap 9, laser beam emitter 8 gives off laser beam;

5. rotate rolling bearing 7, the laser beam that laser beam emitter 8 is sent is aimed at measurement target, can accurately measure the levelness of measured target by the hot spot on the observation measured target.
