DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail in combination with the drawings. The drawings are simplified schematic views, only the basic structure of the utility model is schematically shown, therefore, only the structure related to the utility model is shown.

[0023] Please refer to Figures 1-5 , a measuring scale for house corner surveying, including measuring box body 1, the measuring box body 1 is rectangular frame body, be equipped with a plurality of sliding grooves 11 in the measuring box body 1, be equipped with sliding plate 12 in the sliding groove 11, when the one side of sliding plate 12 is blocked, the whole moves to the other side, the bottom of measuring box body 1 is equipped with groove 14, the folding measuring rod 3 is equipped in the groove 14, under normal circumstances, the measuring rod 3 is retracted in the groove 14.

[0024] In actual measurement use, the house corner can be circular arc, when measuring the circular arc corner, take the measuring box body 1 and push to the arc corner (specifically refer to Figure 6 ), at this time, the sliding plate 12 in contact with the circular arc corner moves to the opposite direction, after moving, the profile of the arc corner will be shown on the sliding plate 12; finally, the arc of the sliding plate 12 can be measured, and the construction qualification can be known by comparing the measurement data; in addition, when the house corner is a right angle, open the measuring rod 3 in the groove 14, when the measuring rod 3 is perpendicular to the measuring box body 1, it can be compared with the right-angled house corner, and the perpendicularity of the house corner can be measured by the measuring rod 3 and the measuring box body 1; therefore, the whole can be applicable to arc corners and perpendicular corners, and the measurement use range is increased.

[0025] In use, in order to avoid the sliding plate from being separated from the measuring box body 1, a limiting protrusion 13 is arranged at one end or both ends of the sliding plate 12, which extends upward along the height direction of the sliding plate 12, and the sliding plate 12 is blocked by the limiting protrusion 13 when moving in the sliding groove 11, so as to avoid the sliding plate 12 from being separated from the measuring box body 1, thereby meeting the repeated measurement use.

[0026] Further, the measuring box body 1 is further provided with a multi-section positioning mechanism at the side away from the limiting protrusion 13, which is used for pressing the extended sliding plate 12, and the positioning mechanism comprises an L-shaped fixed plate 2, a screw rod 21, a pressing plate 22 and a pressing strip 24, the L-shaped fixed plate 2 is arranged on the surface of the measuring box body 1 and flush with the outer wall, the pressing plate 22 is arranged on the outer side of the measuring box body 1, the upper surface of the pressing plate 22 is provided with a bearing 23, and the lower surface is provided with the pressing strip 24, one end of the screw rod 21 penetrates through the L-shaped fixed plate 2 and cooperates with the bearing 23, and the rotation of the screw rod 21 drives the pressing plate 22 and the pressing strip 24 to ascend and descend, and when the pressing plate 22 moves downward, the pressing strip 24 is pressed on the upper surface of the sliding plate 12, wherein the pressing strip 24 is an elastic rubber strip.

[0027] In the embodiment, the positioning mechanism is used for measuring the arc-shaped corner, and when a plurality of sliding plates push the arc-shaped corner, the sliding plate 12 moves in the opposite direction, at this time, the profile of the arc-shaped corner is displayed, at this time, the screw rod 21 is rotated, the screw rod 21 drives the pressing plate 22 and the pressing strip 24 to move downward, so that the pressing strip 24 is pressed on the upper surface of the sliding plate 12, at this time, the pressed sliding plate cannot move in the sliding groove 11, that is to say, after being pressed, the profile of the arc-shaped corner is limited, so as to avoid affecting the measurement accuracy.

[0028] The measuring box body 1 can also be used for continuous arc-shaped corner measurement, and the profile of the continuous arc-shaped corner can be reflected on a plurality of sliding plates 12, and the comparison accuracy is ensured after measurement.

[0029] In addition, one end of the measuring rod 3 is hinged in the recess 14 through a hinge shaft 31, the recess 14 is provided with a locking bolt 33 at the side away from the hinge shaft 31, the locking bolt 33 extends into the measuring rod 3 through the side wall, and after extension, the measuring rod is folded in the recess, when the measuring rod 3 is folded through the locking bolt 33, the bottom surface of the measuring box body 1 is flush with the surface of the measuring rod 3, at this time, the flush bottom surface can be used for measuring the flatness of the wall of the house.

[0030] Since the measuring rod 3 is hinged through the hinge shaft, the measuring rod 3 can rotate 0-180° with the hinge shaft 31 as the center, and can be suitable for wall corner measurement of different angles, and the surfaces of the two sides of the recess 14 and the measuring rod 3 are provided with scales 32, which can also be used for measuring length after being unfolded.

[0031] As Figure 7When the measuring rod 3 is perpendicular to the measuring box body 1, it can be used to detect the perpendicular corner of the house, and when the measuring rod 3 is folded into the groove 14 or fully unfolded, it can be used to detect the wall flatness and length of the house, thereby increasing the use range.

[0032] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Other different forms of changes or variations can be made on the basis of the above description for those skilled in the art. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
