Description

Measuring calipers for building

Technical Field

The utility model relates to a building measuring equipment field specifically is a measurement calliper for building.

Background

The existing application numbers are: chinese patent of CN201721399436.8 discloses a measurement calliper for building, including being used for two measuring support arms, two the support arm is articulated through the articulated shaft, measurement calliper for building still includes two fixed arms, the fixed arm is established in two support arm one sides and is articulated through the articulated shaft, and every fixed arm holds the end including being used for the stiff end that offsets with the wall body and being used for supplying the measurer to hold to avoid two support arms crooked and influence the measurement accuracy in measurement process.

On the basis of the above technique, the utility model provides an another technical scheme to avoid two support arms crooked influence measurement accuracy's problem in the measurement process.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main objective provides a measurement calliper for building, problem in can effectual solution background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a measurement calliper for building, including being used for two measuring support arms, two the support arm passes through the articulated shaft and articulates, still includes the horizon bar, two support arms set up in the hole at horizon bar middle part, the both ends and the interior hole internal surface of articulated shaft rotate to be connected, the internal surface symmetric position of horizon bar both sides rotates and is connected with adjustable stabilizer blade, still be provided with the spirit level post pipe of horizontal direction and vertical direction on the horizon bar, during the use, adjust the interval of stabilizer blade to measuring hole center, make the articulated shaft be located the position at hole center, then through observing the spirit level post pipe, adjust the stabilizer blade, make the horizon bar parallel with the wall, in order to avoid two support arms crooked influence measurement accuracy's problem in the measurement process.

Furthermore, the stabilizer blade includes and is connected the internal thread sleeve pipe with the internal surface rotation of horizon bar, and internal thread sleeve pipe internal surface threaded connection has the screw rod of using with it cooperation, and the one end joint that the screw rod is located the horizon bar below has the fixed foot with the wall body fixed, observes the spirit level post pipe promptly, and the interval of horizon bar both ends and wall body is adjusted to rotatory screw rod to realize the purpose that horizon bar and wall body are parallel.

Furthermore, the fixed feet are sucking discs, so that the supporting feet can be conveniently fixed on a flat wall surface.

Furthermore, the fixing feet are nail claws, so that the supporting feet can be fixed on the uneven wall surface conveniently.

The working principle and the beneficial effects are as follows: through adjusting the interval of stabilizer blade to measuring hole center for the articulated shaft is located the position at hole center, then through observing the spirit level column pipe, adjusts the stabilizer blade, makes the horizon bar parallel with the wall, in order to avoid two support arms crooked influence measurement accuracy's in the measurement process problem.

Drawings

Fig. 1 is a schematic view of the partial cross-sectional structure of the present invention.

In the figure: 1. a support arm; 2. hinging a shaft; 3. a horizontal bar; 4. a level vial; 5. an internally threaded sleeve; 6. A screw; 7. and fixing the feet.

Detailed Description

The invention will be better understood from the following examples.

The drawings in the specification show the structure, ratio, size, etc. only for the purpose of matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and not for the purpose of limiting the present invention, so the present invention does not have the essential meaning in the art, and any structure modification, ratio relationship change or size adjustment should still fall within the scope covered by the technical content disclosed in the present invention without affecting the function and achievable purpose of the present invention. Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

As shown in fig. 1, a measurement calliper for building, including being used for two support arms 1 of measuring, two support arm 1 is articulated through articulated shaft 2, still include horizon bar 3, two support arms 1 set up in the hole at horizon bar 3 middle part, the both ends and the interior internal surface of articulated shaft 2 rotate and are connected, the internal surface symmetric position of horizon bar 3 both sides rotates and is connected with adjustable stabilizer blade, still be provided with the spirit level post pipe 4 of horizontal direction and vertical direction on the horizon bar 3, during the use, the interval of stabilizer blade to measuring hole center has been adjusted, make the articulated shaft be located the position at hole center, then through observing the spirit level post pipe, adjust the stabilizer blade, make horizon bar and wall parallel, in order to avoid two support arms crooked problem that influences the measurement accuracy in the measurement process.

Wherein, the stabilizer blade includes and is connected internal thread sleeve pipe 5 with 3 internal surface rotations of horizon bar, and 5 internal surface threaded connection of internal thread sleeve pipe have the screw rod 6 that uses with it cooperation, and the one end joint that screw rod 6 is located the horizon bar 3 below has the fixed foot 7 fixed with the wall body, observes the spirit level post pipe promptly, and the interval of horizon bar both ends and wall body is adjusted to rotatory screw rod to realize the purpose that horizon bar and wall body are parallel.
