Description

Technical Field

[0001] The utility model belongs to the field of building measurement, in particular to a device for measuring the building area of ​​a real estate. Background Art

[0002] Measuring the building area of ​​a property usually requires the use of a series of professional measuring tools and equipment, including but not limited to tape measures, laser rangefinders, levels, angle measuring instruments, etc. Among them, in daily household use, most people only use tape measures for measurement, because other instruments are relatively expensive and require certain professional knowledge to use.

[0003] When using a tape measure to measure an area, it is easy to measure the length and width, but it is very difficult to measure the height because the material of the tape measure itself is soft. If the user pulls the tape measure upward from the ground to measure, it cannot remain vertical after being pulled out to a certain length. If the tape measure is pulled downward, the user needs to climb to a higher place with the help of a ladder. On the one hand, ladders are not common in households. On the other hand, after being pulled downward for a long distance, the tape measure, whether it is a strip or a strip of steel, cannot remain straight. Utility Model Content

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0019] The real estate building area measuring device provided in this specific embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a ruler component and a splicing component, wherein:

[0020] The ruler bar component comprises a hard ruler 1 and a scale 2 arranged on the hard ruler 1, and the scale 2 is close to the bottom end of the hard ruler 1. That is, when in use, the bottom end of the hard ruler 1 is used to approach the measuring surface for measurement.

[0021] The splicing component includes a rectangular connecting strip 3 installed on the top of the hard ruler 1. The front and back and both sides of the rectangular connecting strip 3 are flush with the hard ruler 1, and its height is much smaller than the height of the hard ruler 1. In addition, the rectangular connecting strip 3 is provided with a snap-fit ​​mechanism 4 for keeping the hard ruler 1 without protruding structures for continuous splicing. Figure 2 As shown, the snap mechanism 4 includes a snap groove 401 that is distributed along the length direction of the rectangular connecting strip 3 and is in the shape of a hole. A movable snap rod 402 is snap-connected in the snap groove 401. The length of the snap rod 402 is equal to half of the length of the snap groove 401. Moreover, the snap rod 402 is an elastic rod. The diameter of the elastic rod is slightly larger than the diameter of the snap groove 401, so that the snap rod 402 can be elastically snapped with the snap groove 401. In this way, when splicing, the snap rod 402 can be inserted into another snap groove 401 for elastic snapping, so that the two hard rulers 1 are spliced ​​together. Since the length of the snap rod 402 is only half of the snap groove 401, after a part of it is inserted into another snap groove 401, the remaining length of the snap groove 401 where it is located is sufficient to accommodate another snap rod 402, so continuous splicing can be performed on the left and right sides.

[0022] In addition, if Figure 2 As shown, the top of the rectangular connecting strip 3 is provided with a limit groove 5 which is parallel to and communicates with the engaging groove 401, and the two ends of the limit groove 5 are close to the outer ends of the rectangular connecting strip 3 but not connected; in addition, the top of the engaging rod 402 is fixedly connected with a convex block 6 which passes through the limit groove 5 and protrudes above the rectangular connecting strip 3, and the convex block 6 is close to one end of the engaging rod 402. The engaging rod 402 can be easily pushed to move by the action of the convex block 6. In addition, on the one hand, the end of the two ends of the engaging rod 402 away from the convex block 6 is a semicircular structure to reduce the friction with the notch of the other engaging groove 401, so as to facilitate the insertion into the engaging groove 401 with less effort. On the other hand, the top of the convex block 6 is provided with a plurality of strip grooves 7 evenly distributed along its length direction, and these strip grooves 7 are constructed to form a resistance structure for increasing the friction with the user's hand, and further facilitating the pushing of the convex block 6 and the engaging rod 402.

[0023] In addition to the above, the rectangular connecting strip 3 and the snap-fit ​​mechanism 4 thereon can also be provided at the bottom of the hard ruler 1 to form a symmetrical assembly with the structure at the top of the hard ruler 1 to increase the splicing stability and reduce the possibility of the hard ruler 1 falling off after splicing.

[0024] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
