Abstract
The utility model relates to a level bar-a combined laser level bar. The existing level bar is that a ruler body is used for measuring, measuring range is limited, and an integral height error of a measured surface can not be relieved if multiple-point measuring is processed. The purpose of the utility model is to provide a combined laser level bar made by laser and optical principles. The structure of the utility model is shown by a figure 1, and the combined laser level bar is composed of a horizontal reference disc and a laser level bar. A laser emission hole (13) is arranged at the end of the laser level bar or an imagery changing lens (15) is arranged in the laser emission hole (13). A point or a line horizontal with the laser emission hole (13) and an image of vertical points can be formed on an object by transmitted laser, and an adjustable horizontal display panel (1) can be rotated for 360 DEG.
Description
The utility model relates to a kind of surveyor's staff---a combined laser surveyor's staff.Surveyor's staff is the survey instrument of people's Measuring Object horizontality commonly used in the production and construction process.Existing surveyor's staff is directly to utilize blade to come the Measuring Object horizontality, and therefore, its measurement range is limited.As carry out multimetering, then can not exempt measured whole height error.
The purpose of this utility model is to provide a kind of combined laser surveyor's staff that forms by laser and optical principle manufacturing.
Its structure of the utility model shown in Fig. 1-4, it by horizontal reference dish (Fig. 2), laser level chi (Fig. 3) and change the picture camera lens (15) combine.
The horizontal reference dish is shown face (1), shaft collar (2), screw rod (3), adjusting knob (4), is only locked screw (5) and dish seat (6) is formed by horizon adjustable.Level shows that bubble (7) is located at the centre position that horizon adjustable shows face (1); Horizon adjustable demonstration face (1) can be made 360 ° of any directions and rotate on shaft collar (2), and is provided with 360 ° of calibration grooves and numerical value on the garden cylinder of horizon adjustable demonstration face (1); The garden cylinder of shaft collar (2) is provided with the calibration zero line; Dish seat (6) center is provided with screw.
The laser level chi is made up of blade (8), parallel bubble (9), vertical bubble (10), laser diode (11), switch (12), laser emission port (13) and magnet steel (14).In horizontal transmitting aperture (13), can load onto and change picture camera lens (15), change picture camera lens (15) and be provided with two kinds; A kind of (I type) image is a horizontal line, and another kind of (II type) image is vertically upward or a downward vertical point.
When using the combined laser surveyor's staff, earlier with adjusting knob (4) adjusting screw(rod) (3), make horizon adjustable show the globule in the bubble (7) in the middle of the face (1) to the circle of garden, center, at this moment, horizon adjustable shows that face (1) is horizontality.The laser level chi is put to horizon adjustable demonstration face (1) last (globule in the parallel bubble (9) at laser level chi middle part places the centre position of parallel bubble (9)), simultaneously, make magnet steel (14) part place horizon adjustable to show in face (1) scope, and the rotation horizon adjustable shows face (1), make the laser level chi be provided with of laser emission port (13) towards object being measured, rotary switch (12) (opening) then, at this moment, on testee, promptly demonstrate an image that becomes the point of level with laser emission port (13); To change picture camera lens (15) (I type) laser emission port of packing into (13), and on testee, can demonstrate one and look like the image that camera lens (15) becomes the line of level with changing; Unload and change picture camera lens (15) (I type), pack into and change picture camera lens (15) (II type), promptly on the projected objects of vertical direction (up or down), demonstrate the image of a vertical point.If need testee is carried out calibration, only need the rotation horizon adjustable to show face (1), the calibration groove on the cylinder of adjusting horizon adjustable demonstration face (1) garden and the relative position of the calibration zero line on the cylinder of shaft collar (2) garden, and with only locking screw (5) location, can on testee, find corresponding laser emission point, finish the calibration requirement of testee; With adjusting knob (4) adjusting screw(rod) (3), can make the upper and lower adjusting in horizontal reference position of measurement; The laser level chi can be used for the level or the plumbness of Measuring Object separately by observing parallel bubble (9) or vertical bubble (10), and the combined laser surveyor's staff can be used by hole and the tripod that is located at dish seat (6) center.
This combined laser surveyor's staff mainly adopts metal material, laser diode and optical lens manufacturing to form.
The Laser emission distance of this combined laser surveyor's staff can reach 20-30 rice (shining the body harmless), and the horizon adjustable chi shows that face (1) can 360 ° of rotations.Therefore, be applicable to very much the horizontal survey of large tracts of land scope.The verticality of water detection flat spot, calibration and the higher object of measurement etc.
This combined laser surveyor's staff is easy to use, and point, line image are clear, the accuracy height.Therefore have practicality preferably and promotional value.
Claims (3)
1, a kind of combined laser surveyor's staff, it is characterized in that it is combined by horizontal reference dish and laser level chi: the horizontal reference dish is shown face (1), shaft collar (2), screw rod (3), adjusting knob (4), is only locked screw (5) and dish seat (6) is formed by horizon adjustable, shows that at horizon adjustable face (1) center is provided with level demonstration bubble (7); Horizon adjustable shows that face (1) can rotate on shaft collar (2), and is provided with 360 ° of scale division values on its face of cylinder; Laser level chi one end is provided with laser emission port (13), can level launch laser, and the image of light on object is a point.
2, combined laser surveyor's staff according to claim 1 is characterized in that can loading onto in laser emission port (13) and changes picture camera lens (15), and making the image of laser beam on object is a horizontal line or a point vertical with surface level.
3, combined laser surveyor's staff according to claim 1 and 2 is characterized in that being provided with in the laser level chi magnet steel (14).
