[0001] The utility model relates to the technical field of building measurement, in particular to a building area measuring device. Background Art

[0002] With the progress of society, more and more buildings are being built. After the construction of a building is completed, the indoor building area of ​​the building needs to be measured and calculated. Generally, the operator uses a handheld infrared rangefinder to measure the length, width and height data of various places in the building, and then obtains the building area data after conversion.

[0003] The manual measurement method has the following disadvantages: when manually holding the infrared rangefinder for measurement, due to the poor stability of the hand, the laser emitted by the infrared rangefinder is prone to deflection, resulting in large errors in the measurement results; since the infrared rangefinder itself has a certain height, when measuring the height of the room, it is necessary to manually flip the infrared rangefinder upside down to measure the height below the infrared rangefinder and complete the measurement of the entire height. However, due to the poor stability of the hand, the height of the infrared rangefinder is easily changed during the flipping process, resulting in measurement errors. For this reason, we propose a building area measurement device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 , 2 4. The utility model provides a technical solution: a building area measuring device, including a mobile base 1 and an adjusting disk 5. A positioning sleeve rod 2 is fixedly installed on the top of the mobile base 1, and a lifting rod 3 is clamped inside the positioning sleeve rod 2. A locking knob 4 that cooperates with the lifting rod 3 is threadedly connected on the positioning sleeve rod 2. The overall height of the adjusting disk 5 can be adjusted by cooperating with the positioning sleeve rod 2 and the lifting rod 3. After the adjustment, the lifting rod 3 can be locked again by rotating the locking knob 4. A connecting ear 11 that cooperates with the lifting rod 3 is provided at the bottom of the adjusting disk 5. The connecting ear 11 is hinged to the top of the lifting rod 3. A locking knob 2 12 is threadedly connected to the connecting ear 11. After the adjusting disk 5 is adjusted to a vertical state, the end of the locking knob 2 12 is tightened into the corresponding locking hole 13 to achieve adjustment. The adjusting disk 5 is re-locked to ensure the stability of the infrared rangefinder 10 during measurement. An electric indexing disk 6 is fixedly installed on the top of the adjusting disk 5, and a mounting disk 7 is fixedly connected to the top of the electric indexing disk 6. The electric indexing disk 6 drives the mounting disk 7 to rotate to adjust the measuring direction of the infrared rangefinder 10. When the adjusting disk 5 is in a horizontal state, the distance between the two vertical walls can be measured. When the adjusting disk 5 is in a vertical state, the distance between the ground and the ceiling can be measured. An infrared rangefinder 10 is arranged in the middle of the top of the mounting disk 7. The horizontal or vertical state of the infrared rangefinder 10 is adjusted by the adjusting disk 5, and the measuring direction of the infrared rangefinder 10 is adjusted. Not only the area of ​​a certain side wall can be measured, but also the area of ​​a horizontal building can be measured.

[0023] See also Figure 5The connecting ear 11 is located at the center of the bottom of the adjusting disk 5. The adjusting disk 5 can rotate left and right with the connection point between the connecting ear 11 and the lifting rod 3 as the axis point. The infrared rangefinder 10 is adjusted to a vertical state through the adjusting disk 5, so that the infrared rangefinder 10 can measure the distance between the ground and the ceiling. Four groups of evenly distributed locking holes 13 are opened at the end of the lifting rod 3. The four groups of locking holes 13 are located on the surrounding side of the connection point between the lifting rod 3 and the connecting ear 11. After the adjusting disk 5 is adjusted to a vertical state, the end of the locking knob 12 is tightened into the corresponding locking hole 13 to achieve re-locking of the adjusting disk 5, thereby ensuring the stability of the infrared rangefinder 10 during measurement.

[0024] See also Figure 2 , 3 A positioning frame 8 for the infrared rangefinder 10 to be connected is provided on the top of the mounting plate 7, and the size of the positioning frame 8 is adapted to the infrared rangefinder 10. The position of the infrared rangefinder 10 is limited by the positioning frame 8 to ensure that the infrared rangefinder 10 can be stably connected to the top of the mounting plate 7, so that the infrared rangefinder 10 can work stably. The infrared rangefinder 10 is located at the center of the top of the mounting plate 7. Since the infrared rangefinder 10 itself has a certain size, when measuring the distance between the infrared rangefinder 10 and both sides of a certain building surface, the measured value can be added to the size of the infrared rangefinder 10 itself to ensure the measurement accuracy of the infrared rangefinder 10.

[0025] The top of the mounting plate 7 is provided with locking components 9 located on both sides of the positioning frame 8, and the locking components 9 include a mounting back plate 91, a locking claw 92, and a compression spring 93. The infrared rangefinder 10 is positioned by the positioning frame 8 and is restricted to be installed on the top of the mounting plate 7 by two sets of locking components 9, so as to ensure the stability of the infrared rangefinder 10 during operation and thereby improve the accuracy of the measurement. The mounting back plate 91 is fixedly mounted on the side of the positioning frame 8, and the locking claw 92 is movably mounted on the mounting back plate 91. The outer movable sleeve of the locking claw 92 is provided with a compression spring 93. The locking claw 92 is pulled to move toward the side close to the mounting back plate 91 to release the restriction of the locking claw 92 on the infrared rangefinder 10, so as to facilitate the disassembly and assembly of the infrared rangefinder 10 and reduce the difficulty of operation.

[0026] See also Figure 5 The mobile base 1 is provided with gaps around it to match the infrared rangefinder 10, so as to prevent the mobile base 1 from interfering with the infrared rangefinder 10 in ground measurement. Two sets of universal wheels 14 are movably installed on one side of the bottom of the mobile base 1, and two sets of directional wheels are movably installed on the other side. The universal wheels 14 are provided with brake plates, which facilitate the movement of the device through the universal wheels 14 and the directional wheels, and the device can be locked as a whole through the brake plates.

[0027] In summary, when the building area measuring device is used, the device is moved to the position to be measured by the universal wheel 14 and the directional wheel, and the position of the device is calibrated by the handheld level. For example, when measuring the area of ​​a certain side wall, the handheld level is placed on the top of the mounting plate 7 for calibration, so that the infrared rangefinder 10 is parallel to the side wall to be measured. After the device is calibrated, the position of the device is locked by the brake plate on the universal wheel 14, and the infrared rangefinder 10 is started. The infrared rangefinder 10 measures the distance between it and one side of the side wall to be measured, and the mounting plate 7 and the infrared rangefinder 10 are driven by the electric dividing plate 6 to rotate 180° to measure the distance between it and the other side of the side wall to be measured. The sum of the two sets of values ​​is the length dimension of the side wall to be measured; rotate the locking knob 12 to flip the adjusting disk 5 as a whole by 90 degrees, adjust the infrared rangefinder 10 to a vertical state, and after adjustment, tighten the locking knob 12 in the corresponding locking hole 13 to re-lock the adjusting disk 5, start the infrared rangefinder 10, and the infrared rangefinder 10 passes through the notch on the mobile base 1 to measure the distance between it and the ground. The electric dividing plate 6 drives the mounting plate 7 and the infrared rangefinder 10 to rotate 180° to measure the distance between it and the ceiling. The sum of the two sets of values ​​is the height dimension of the side wall to be measured, and the length dimension of the side wall to be measured is multiplied by the height dimension to calculate the area of ​​the side wall to be measured.
