Description

Telescopic level meter

Technical field

The utility model belongs to the survey instrument field, relates in particular to a kind of telescopic level meter.

Background technology

The existing level instrument is used for judging whether level of certain determinand, but the existing level instrument often length fix, can not adapt to well for the measurement occasion that needs extension length, and then influence measuring accuracy.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of telescopic level meter is provided.

The technical solution of the utility model is: a kind of telescopic level meter, comprise outer chi, and outer chi is provided with spirit bubble, in the outer chi gear assembly is housed, and the gear assembly engagement is arranged on the tooth bar on the telescopic arm, and an end of telescopic arm also is connected with upright arm.

As of the present utility model a kind of preferred, respectively be provided with a guide-track groove on the top inner wall of outer chi and the bottom interior wall, two guide-track grooves are slidingly matched respectively and are arranged on two guide rails on the telescopic arm.

As of the present utility model a kind of preferred, gear assembly includes the odd number intermeshed gear, and the two ends of gear are equipped with rotation axis, and the rotation axis rotation hole interior with being arranged on outer chi matches.

As of the present utility model a kind of preferred, upright arm is provided with projection, and projection is connected to the groove that is arranged on the telescopic arm.

As of the present utility model a kind of preferred, also be provided with fixed orifice and chute on the upright arm.

As of the present utility model a kind of preferred, the shape of cross section of guide-track groove, guide rail, projection and groove is trapezoidal or arc or square.

As of the present utility model a kind of preferred, the cross sectional shape of chute is a waist shape.

In sum, the utlity model has following advantage:

1, the utility model will be provided with the outer chi of spirit bubble as fixed part, gear set is placed in the outer chi again, and rotatablely moving of gear set changed into the rectilinear motion of tooth bar by the rack-and-pinion transmission, telescopic arm will change with respect to the length of outer ruler end part so, so Zheng Ti length will change, thereby can adapt to the application of different occasions.When not using this to implement when novel, telescopic arm can be drawn in outside in the chi, can be convenient for carrying.

2, the utility model is provided with guide rail on telescopic arm, and the guide rail guide-track groove in the outer chi that is slidingly matched can be avoided the friction of telescopic arm and outer chi inwall, has improved sport efficiency, and is more laborsaving during use.

3, the utility model is designed to the odd number intermeshed gear with gear assembly, so when a telescopic arm slides, driven the rotation of gear assembly, gear assembly drives another telescopic arm again and slides, and the gear set that comprises the odd number gear makes that the direction of motion of two telescopic arms is opposite, just motion in the other direction of another telescopic arm when the motion of telescopic arm so easy and simple to handlely like this need not to operate simultaneously two telescopic arms.

The connected mode of 4, the utility model is preferred upright arm and telescopic arm makes that both connections are more firm.

5, upright arm links to each other with the object that needs the detection of vertical degree, because upright arm is perpendicular with the direction of outer chi spirit bubble, thereby can be converted into verticality the measurement levelness, has simplified operation.And can conveniently regulate installation dimension by chute and fixed orifice, to adapt to the UUT of different length.

6, the utility model is the also preferred cross sectional shape of guide-track groove, guide rail, projection and groove makes when cooperating more firm.

Embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.

Shown in Fig. 1 to 6, a kind of telescopic level meter, the outer chi 1 of cube that comprises hollow, outer chi 1 is provided with spirit bubble 1a, in the outer chi 1 gear assembly 2 is housed, gear assembly 2 includes 1 gear 2a, and the two ends of gear 2a are equipped with rotation axis 2a1, and rotation axis 2a1 matches with rotation hole 1c in being arranged on outer chi 1.Gear 2a engagement is arranged on the tooth bar 3a on the telescopic arm 3, and an end of telescopic arm 3 also is connected with upright arm 4.Respectively being provided with a cross sectional shape on the top inner wall of outer chi 1 and the bottom interior wall is trapezoidal guide-track groove 1b, and two guide-track groove 1b are slidingly matched respectively and are arranged on two cross sectional shapes on the telescopic arm 3 is trapezoidal guide rail 3b.Upright arm 4 is provided with protruding 4a, and protruding 4a is connected to the groove 3c that is arranged on the telescopic arm 3.The shape of cross section of projection 4a and groove 3c is trapezoidal.Also be provided with fixed orifice 4b and chute 4c on the upright arm 4.The cross sectional shape of chute 4c is a waist shape.

The utility model can be used for the installation of outdoor machine of air-conditioner, and what waste time and energy most in the installation of outdoor machine of air-conditioner is straight to the levelling of air-conditioning erecting frame in the high-altitude.The utility model can directly reach operations such as regulating the air conditioning room distance in the indoor levelling of finishing the air-conditioning erecting frame, and its method is as follows:

The first step is opened and is taken out outer chi 1, and telescopic arm 3 is pulled out from outer chi 1.
