Abstract

The utility model relates to a self-adjusting leveler which is mainly composed of a level seat, a light beam index device, a base, etc. The utility model is characterized in that the light beam index device arranged in a seat body which can be adjusted automatically and horizontally uses the good focusing function of the light beam to obtain the accurate and convenient effect on adjustment without the limitation of the space when the level correction is finished.

Description

The self-regulated level meter

The utility model relates to a kind of self-regulated level meter in the surveying instrument, is meant that a kind of light beam that utilizes locatees as index, and can advance the level measurement device of accuracy of measurement.

A workman must first sharpen his tools if he is to do his work well, installs at many civil constructions and machinery, and accurate horizontal survey is necessary and indispensable, and such as on civil engineering work: ground horizontal datum, template die set up, block group brick, adherent brick etc.; Decorateing on the engineering: indoor compartment, ceiling set up etc.; In mechanical engineering: the installation of large-scale machine-tool, overhead traveling crane engineering, gravity flow conveyor etc..In considerable occasion, good horizontal is measured the important foundation that operation is construction quality and safety.

The conventional practice of horizontal survey, it generally is the principle of utilizing the bubble come-up, judge that with eyesight whether the equilibrium position of bubble in it is used as the foundation of level with the buoy chamber of a pipe shape, or the water pipe of water is housed in utilizing more simply, examine opposite views, measure horizontal level with the principle that height of water level equates, as shown in Figure 1.

Above horizontal survey of lifting conventional practice is subjected to the restriction in space, can't use in apart from occasion long, and merely with the eyesight observation bubble practice of balance whether, its accuracy rate of measuring is very low with this kind.Moreover, on the horizontal level standard of level meter itself, conventional practice is to utilize several horizontal adjustment screws to rotate up and down and proofread and correct its inclination, whether observe bubble reaches in the equilibrium position as determining device horizontality foundation, yet ask for quite inconvenience of horizontal process with the horizontal adjustment screw, expend time in and seldom arrive calibration result, influence operating efficiency.

For this reason, the purpose of this utility model will provide a kind of and measure accurately, operation is simple and easy, utilize the level measurement device of light beam as the index location, and it has solved existing with the aforementioned many deficiencies such as distance limit that are subjected to that exist in the horizontal survey practice.

Realize that the utility model purpose is to have the horizontal pedestal of inside and outside axis of swing and base as agent structure of the present utility model by one, interior swinging center is provided with light beam generator can be from the light beam outgoing beam that portals, because the well focussed function of light beam, under long distance, still can have the location indicative function, cooperate outer pendular ring again, the extension one vertical body that weighs in the middle of the axis of swing in bracing frame reaches can be free arbitrarily to swinging to reach the action from level-off.The horizontal base body device can be done revolution use at any angle in 360 degree on base.

Describe in detail below in conjunction with accompanying drawing and as embodiment:

The utility model provides accompanying drawing as follows:

Fig. 1 is the synoptic diagram of traditional horizontal calibrating mode;

Fig. 2 is the three-dimensional view of the utility model embodiment;

Fig. 3 is a utilization synoptic diagram of the present utility model;

Fig. 4 is the sectional view of the utility model light beam pointer and the heavy body that hangs down.

Ask for an interview Fig. 2, the utility model mainly includes horizontal pedestal 10, base 30, also includes light beam pointer 20, and this horizontal pedestal 10 structurally can be divided into bracing frame 11, interior axis of swing 14, swings annulate shaft 13, angle scale 16 and a vertical heavy body 15 outward.On the angle scale 16 of movable rotation, can make scale indication angle, angle scale 16 is assembled in base 30 upper ends, can do 360 degree rotations, base 30 lower ends have several to adjust screw 31, can be for steadily setting up use, 17 is trip bolt, base can be installed foot rest 32 30 times, as shown in Figure 3, to make the support usefulness of this device, base 30 is in the form of annular discs, establishing horizontal pedestal 10 on it has the bracing frame 11 of two balanced configurations, 11 of bracing frames support an outer swing 12 by an outer swing annulate shaft 13, swing annulate shaft 13 outward and link to articulate with mode and bracing frame 11, and therefore feasible outer pendular ring 12 can move back and forth; In addition, axis of swing 14 in the pendular ring inner edge also links in the mode that articulates outside this, the direction that is provided with of interior axis of swing 14 just meets at right angles with aforesaid outer swing annulate shaft 13 and does backswing, interior axis of swing is hung a vertical heavy body 15 for 14 times, therefore, this heavy body 15 that hangs down can freely be done all around comprehensive swing and reach purpose from level-off, in addition, one bubble observation window (figure do not draw) also can be installed, with as device whether the affirmation of horizontality use.

Fig. 3 is the user mode figure of the utility model self-regulated level meter, and wherein horizontal pedestal has foot rest 32 10 times, and light beam 231 is the 21 conduct paths of both sides emitted light beams 231 to the left and right of portalling of the light beam from the utility model self-regulated level meter.

Fig. 4 is the sectional view of the utility model light beam pointer and the heavy body that hangs down, in the vertical heavy body 15 battery 22 is arranged, in light beam pointer 20, upper end one spherical 24 of vertical heavy body 15 is satisfied with in the depression 25 from top to bottom, depression 25 is the basipetal hollow circular cylinder in axle center, the lower end of hollow round column body also be a diameter than the diameter of spherical 24 is little hollow circular cylinder 26 hereinto, for spherical 24 swing in depression 25 freely.

Axis of swing 14 in light beam pointer 20 includes, one or two conventional beam generator 23 and the light beam at interior axis of swing 14 two ends portal 21.Light beam generator 23 is by condenser lens on the straight line of the axle center of interior axis of swing 14 to two light beams, 21 light beams 231 that penetrate that portal, and light beam generator 23 is by the battery supply power that is located in heavy body 15 inside of hanging down.The heavy body 15 that hangs down is that the female screw with the upper end screws togather to the pin thread of spherical 24 lower ends.

The utility model can accurately use this self-regulated level meter to horizontality for the user apace, but in practical operation the one-man service, improve effect.
