Description

Technical Field

[0001] This invention belongs to the field of building measurement technology, and specifically relates to a measuring device for measuring building area. Background Technology

[0002] During urban redevelopment and demolition, it is necessary to measure the houses to be demolished. When measuring the interior area, a measuring tape is required, and two people are needed to work together. In addition, when measuring the height of the house, ladders and other tools are needed to climb to a high place and take the measurement. The measurement is time-consuming, and in order to ensure the accuracy of the data, multiple measurements are required and the average value is taken, which further increases the working time. Therefore, the existing technology needs further improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a portable measuring device that can measure multiple data points at once, shortening measurement time and reducing manpower for house area surveying.

[0004] A measuring device for measuring the area of ​​a building includes a first vertical plate and a second vertical plate. A rotating roller is rotatably connected to one edge of the surface of the first and second vertical plates. The rotating roller is hollow inside, and a hydraulic cylinder is fixedly sleeved inside the lower part of the rotating roller. The cylinder body is fixed inside the lower part of the rotating roller. The extension rod of the hydraulic cylinder faces upward and is connected to a first extension rod. Both the hydraulic cylinder extension rod and the first extension rod are provided with length scale values. Several first measuring tape holders are provided on the vertical edge of the first vertical plate along its length direction. The first measuring tape is placed in a first measuring tape holder, which has a through hole for the tape measure to pass through. The other end of the first measuring tape is equipped with a gravity fixing component. Several second measuring tape holders are placed on the vertical edge of the second upright plate along its length. The second measuring tape holders are placed in a second measuring tape holder, which has a through hole for the tape measure to pass through. The other end of the second measuring tape is equipped with a gravity fixing component.

[0005] Furthermore, the adjacent side surfaces of the first and second upright plates are provided with magnets that can attract each other.

[0006] Furthermore, the gravity fixing component includes a gravity block, with a vertical rod on the upper surface of the gravity block. The end of the first or second measuring tape can be detachably connected to the vertical rod. The lower surface of the gravity block is provided with a replaceable adhesive ring and a detachable suction cup. The adhesive ring is a plastic ring with adhesive on both sides of its axial surface. The adhesive is covered with a tear-off film. The lower surface of the gravity block is provided with a groove for the upper end of the suction cup to be connected. The suction cup is facing downwards, and the upper end of the suction cup is provided with an external thread. The groove is provided with an internal thread that mates with the external thread, forming a detachable suction cup structure.

[0007] Furthermore, the upright has several strip-shaped through holes, the length direction of which is the same as the length direction of the upright. The ends of the tapes of the first and second measuring tapes are connected to circular cards that can pass through the strip-shaped through holes.

[0008] Furthermore, the first measuring tape holder and the second measuring tape holder are located on adjacent surfaces of the first and second upright plates, respectively.

[0009] This invention uses a first upright plate and a second upright plate to fix several first and second measuring tape placement boxes. The first and second measuring tapes are placed in the first and second measuring tape placement boxes respectively. The first and second measuring tapes can measure the width or length of the interior of a house. Moreover, multiple first and second measuring tape placement boxes can be used at the same time to obtain multiple data at once, eliminating the need for repeated measurements. Furthermore, the height of the house can be measured by means of a hydraulic cylinder telescopic rod and a first telescopic rod. It is convenient to use. When not in use, the first and second upright plates can be combined and the gravity fixing components can be removed to reduce storage space and facilitate carrying. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1

[0018] like Figure 1-7The measuring device shown includes a first vertical plate 1 and a second vertical plate 2. A rotating roller 3 is rotatably connected to one edge of the surface of the first vertical plate 1 and the second vertical plate 2. The rotating roller 3 is hollow inside, and a hydraulic cylinder 4 is fixedly sleeved inside the lower part of the rotating roller 3. The cylinder body of the hydraulic cylinder 4 is fixed inside the lower part of the rotating roller 3. The hydraulic cylinder telescopic rod 401 faces upward and is connected to the first telescopic rod 402. Both the hydraulic cylinder telescopic rod 401 and the first telescopic rod 402 are provided with length scale values. Three first measuring tape placement boxes 5 are provided on the vertical edge of the first vertical plate 1 along its length direction. Several first measuring tape placement boxes 5 are arranged vertically along the vertical edge of the first vertical plate 1. The first measuring tape 6 is placed in a first measuring tape holder 5, which is evenly spaced along the length of the edge. The first measuring tape holder 5 has a through hole 10 for the tape of the first measuring tape 6 to pass through, and the other end of the first measuring tape 6 has a gravity fixing member 7. Three second measuring tape holders 8 are arranged along the vertical edge of the second upright plate 2, and are evenly spaced along the length of the vertical edge. A second measuring tape 9 is placed in each of the second measuring tape holders 8, which has a through hole 10 for the tape of the second measuring tape 9 to pass through, and the other end of the second measuring tape 9 has a gravity fixing member 7. The adjacent sides of the first upright plate 1 and the second upright plate 2 are provided with mutually attractive magnetic pieces 11. The gravity fixing component 7 includes a gravity block 71. A vertical rod 72 is provided on the upper surface of the gravity block 71. The end of the vertical rod 72 can be detachably connected to either the first measuring tape 6 or the second measuring tape 9. A replaceable adhesive ring 73 and a detachable suction cup 74 are provided on the lower surface of the gravity block 71. The adhesive ring 73 is a plastic ring 731, with adhesive adhering to both sides of its axial surface. A tear-off film covers the adhesive. The suction cup 74 faces downwards and has an external thread at its upper end. A groove 75 is provided at the lower part of the gravity block 71 for the upper end of the suction cup 74 to connect to. An internal thread in the groove 75 engages with the external thread at the upper end of the suction cup 74, forming a detachable structure between the gravity block 71 and the suction cup 74. The vertical rod 72 has three strip-shaped through holes 76, the length of which is the same as the length of the vertical rod 72. Circular cards 77 that can pass through the strip-shaped through holes 76 are connected to the ends of the tapes of both the first measuring tape 6 and the second measuring tape 9. The first measuring tape holder 5 and the second measuring tape holder 8 are respectively located on adjacent surfaces of the first upright plate 1 and the second upright plate 2. The measuring tape used in this invention is a commercially available metal measuring tape with an automatically retractable tape.

[0019] In use, first pass the circular card 77 through the strip-shaped through hole 76, aligning the thicker side of the circular card 77 with the strip-shaped through hole 76. Then, ensure the axial radius of the circular card 77 is greater than the width of the strip-shaped through hole 76. Place the gravity block 71 of the gravity fixing component 7 on one edge of the wall where the distance needs to be measured. If the ground is a floor, peel off the tear-off film on both sides of the adhesive ring 73, and stick one side of the adhesive ring 73 to the lower surface of the gravity block 71, while sticking the other side of the adhesive ring 73 to the floor. Then, pull the first measuring tape 6 or the second measuring tape 9 to place the first upright plate 1 and the second upright plate 2 at the angle between the corners of the wall. Calculate the measured dimensions. During the calculation, add the height of the measuring tape box to the measuring tape dimensions. If measuring the height of the room, first pull out the first telescopic rod 402, then adjust the hydraulic cylinder 4 to extend the hydraulic cylinder telescopic rod 401. Add the length of the extended hydraulic cylinder telescopic rod 401 to the length of the first telescopic rod. The length of the first telescopic rod 402 is fixed after reaching its maximum length, and is simply the length of the hydraulic cylinder telescopic rod 401. When not in use, the gravity fixing component 7 is removed, and the two adjacent magnetic plates attract each other, causing the first upright plate 1 and the second upright plate 2 to close together. At this time, the positions of the first measuring tape holder 5 and the second measuring tape holder 8 are staggered, which ensures that the distance between the first upright plate 1 and the second upright plate is closer when they are closed, which is beneficial for the magnetic plates 11 to attract each other.
