Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of real estate measurement, in particular to a real estate size registration benchmark. Background Art
[0002] Real estate refers to objects that occupy a fixed position in space by natural properties or legal provisions and whose economic value will be affected by movement, including land, land fixtures, land products that have not yet been separated from the land, and other objects that are attached to the land by nature or man and cannot be separated; in order to fully reflect the basic situation of real estate and the division of ownership boundaries, and facilitate land utilization, planning, management and decision-making, we usually survey and map it, which requires the use of various surveying and mapping equipment. Surveying poles are one of the measuring tools. The main body of the real estate is generally in the shape of a pole, and the surface is usually coated with red and white to mark the measuring points.
[0003] The existing real estate dimension registration poles often encounter the following problems during use. Specifically, the pole is usually a long straight rod with a fixed measuring range. In order to increase the measuring range, the existing method is to replace the above-mentioned rod with a telescopic rod. However, due to the cross-sectional size and length limitations of the outermost rod of the telescopic rod, its telescopic length is limited, that is, its measuring range is actually fixed, which is inconvenient to use. In addition, after the existing rod is fixed, it can only measure a measuring point in a single vertical direction and cannot quickly measure the vertical distance between two measuring points located in different vertical directions. In addition, there is often a certain distance between the rod and the measuring point in the horizontal plane, which results in the reading of the value based on the scale on the rod being not fast and accurate enough.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0046] See attached Figure 1 , Attachment Figure 3 and attached Figure 5The embodiment of the utility model discloses a real estate size registration benchmark, including a base 1, at least one rod body 2, an indicating assembly 3, a locking assembly 4, and a leveling mechanism 5. The base 1 is arranged horizontally, and the middle part of the base 1 is rotatably connected to a rotating member 6. The surface formed when the rotating member 6 rotates is located in the horizontal plane; the rod body 2 is arranged vertically, and different rod bodies 2 are detachably connected in the vertical direction. The bottom of the lowest rod body 2 is detachably connected to the top of the rotating member 6. A guide portion 21 and a height scale 22 are provided on the rod body 2. The guide portion 21 and the height scale 22 are both arranged and adjacent in the vertical direction. The two guide parts 21 abut against each other; the indicating component 3 is arranged horizontally and is connected to the guide part 21 with a damping slide, which is used to indicate the measuring point and cooperate with the height scale 22 to obtain the height of the measuring point; the locking component 4 is installed on the base 1 and is arranged corresponding to the rotating part 6, which is used to fix the relative position of the base 1 and the rotating part 6; the leveling mechanism 5 includes a spirit level 51 and multiple leveling components 52, which are all arranged on the base 1, and the spirit level 51 is used to detect the levelness of the base 1. The bottom of the leveling component 52 abuts the ground, which is used to adjust the distance between the bottom of the base 1 and the ground.
[0047] In actual use, the base 1 is placed near the measuring point, and the base 1 is adjusted to a horizontal state through the leveling mechanism 5. Specifically, the distance between each part of the bottom of the base 1 and the ground is adjusted through multiple leveling components 52, and then the level 51 is used to determine whether the base 1 is in the horizontal plane. After the base 1 is leveled, the rod body 2 is rotated in the horizontal plane through the rotating member 6, and the indicating component 3 is moved in the vertical direction through the guide part 21 until the indicating component 3 is aligned with the measuring point. At this time, according to the height scale 22 corresponding to the indicating component 3, the height of the measuring point can be quickly and accurately obtained. When it is necessary to measure another measuring point in the same vertical direction, the relative position of the base 1 and the rotating member 6 can be fixed by the locking component 4, so that the indicating component 3 can move up and down in the same vertical plane. When it is necessary to measure another measuring point in a different vertical direction, the rotating part 6 can continue to be rotated in the horizontal direction and the indicating assembly 3 can be moved in the vertical direction to measure the height of the other measuring point. After the measurement is completed, the vertical distance between the two measuring points can be quickly obtained based on the numerical difference. In addition, since different rod bodies 2 are detachably connected in the vertical direction, a guide portion is provided on the rod body 2 and two adjacent guide portions 21 in the vertical direction abut against each other, so the indicating assembly 3 can be moved directly from one guide portion 21 to another adjacent guide portion 21, thereby increasing the moving range of the indicating assembly 3. In general, by using the real estate dimension registration benchmark, the measuring range can be increased, which facilitates the accurate measurement of the height of a specified measuring point and the vertical distance between two measuring points located in different vertical directions.
[0048] It should be noted that this application does not limit the specific method and structure of the detachable connection of different rod bodies 2 in the vertical direction, which can be flexibly selected according to actual needs. In this embodiment, the bolt connection method is selected, which has the advantages of simple structure, reliable connection, and easy disassembly and assembly.
[0049] See attached Figure 3 Furthermore, the spirit level 51 can be embedded in the base 1 to keep the base 1 flat.
[0050] See attached Figure 1 , Attachment Figure 3 and attached Figure 6 The specific structure and indication method of the indicating component 3 are not limited in this application and can be selected according to actual needs. For example, in order to be able to obtain the distance between two measuring points, the following design is made in this embodiment. Specifically, the base 1 is provided with an angle scale 101 corresponding to the rotating member 6, and the rotating member 6 is provided with a pointer 61 corresponding to the angle scale 101. The indicating component 3 is a telescopic rod with a length scale, so that the real estate size registration benchmark can measure the distance between two measuring points located in different spatial positions.
[0051] Through the design of the above structure, since the indicator component 3 is a telescopic rod with a length scale, the horizontal distances between the two measuring points and the rod body 2 can be measured according to the indicator component 3, which are named here as the first side and the second side. The angle between the first side and the second side in the horizontal direction can be obtained according to the cooperation between the pointer 61 and the angle scale 101, and the vertical distance between the two measuring points can be obtained according to the height scale 22. By combining the above parameters, the actual distance between the two measuring points can be calculated.
[0052] It should be noted that, since the telescopic rod with a length scale is a prior art and has a relatively simple structure, it is not shown in the drawings in this application.
[0053] Furthermore, the following design is carried out in this embodiment. Specifically, the height scale 22 on each rod body 2 is the same, and different rod bodies 2 are provided with coatings of different colors.
[0054] Through the design of the above structure, since the height scales 22 on each rod body 2 are the same, when different rod bodies 2 are connected and assembled, there is no need to sort them according to the different height scales 22, and they can be used as they please, which is convenient and fast; after the connection is completed, since different rod bodies 2 are provided with coatings of different colors, it is easy to distinguish different rod bodies 2, easy to determine the specific number of rod bodies 2, and also easy to read the value; as to why it is easy to read the value, specifically, since the height scales 22 on different rod bodies 2 are the same, the value cannot be directly read according to the height scale 22 corresponding to the indicating assembly 3, but the height scale 22 corresponding to the indicating assembly 3 plus the number of rod bodies 2 below is multiplied by the total value of the height scale 22 on each rod body 2, and the sum of the above results is the actual height of the measuring point, so the number of rod bodies 2 can be quickly distinguished and determined, and the result can be calculated more conveniently and quickly.
[0055] See attached Figure 4 and attached Figure 5 There are various structures that can be used for guiding, and one of them is introduced in this embodiment. Specifically, the guide part 21 is a T-shaped guide rail, and a slot 23 corresponding to the guide part 21 is provided on the other side of the rod body 2 relative to the guide part 21, so that the guide part 21 on one rod body 2 can be inserted into the slot 23 on the other rod body 2.
[0056] Through the design of the above structure, on the basis of the guide portion 21 satisfying the guidance, different rod bodies 2 can also be connected in the horizontal direction through the cooperation of the slot 23, which is convenient for storage.
[0057] See attached Figure 1 and attached Figure 6 There are various ways and structures for indicating a measuring point in the horizontal direction. In addition to the telescopic rod-style indicating assembly 3, this embodiment introduces another structure. Specifically, the indicating assembly 3 includes a slider 31 and a laser emitter 32. The slider 31 is connected to the guide portion 21 with a damping sliding so that the slider 31 can move along the extension direction of the guide portion 21; the laser emitter 32 is detachably connected to the slider 31 and can emit light in the horizontal plane to indicate the measuring point. The total weight of the slider 31 and the laser emitter 32 is less than the friction between the slider 31 and the guide portion 21 to prevent the slider 31 from automatically sliding down.
[0058] Through the design of the above structure, compared with the telescopic rod structure, the measurement point can be indicated more conveniently, quickly and accurately by light; it should be noted that the laser emitter 32 alone cannot measure the horizontal distance between the measurement point and the rod body 2. If you want to measure the above parameters, you need to use a laser rangefinder; further, this application does not limit the detachable connection method between the laser emitter 32 and the slider 31, which can be flexibly selected according to actual conditions. For example, the use of a magnetic connection method can make its disassembly and assembly more convenient and quick.
[0059] See attached Figure 1 , Attachment Figure 3 and attached Figure 7 In order to fix the relative position of the rotating member 6 and the base 1, the locking assembly 4 is designed as follows in this embodiment. Specifically, a first threaded hole 102 corresponding to the rotating member 6 is provided on the side of the base 1. The locking assembly 4 includes a locking bolt 41 and a handle 42. The locking bolt 41 is engaged in the first threaded hole 102; the handle 42 is provided at the end of the locking bolt 41 away from the rotating member 6.
[0060] Through the design of the above structure, when the handle 42 is rotated, the locking bolt 41 can rotate accordingly and move closer to abut and lock the rotating member 6, or move away from and release the locking of the rotating member 6; it has the advantages of simple structure and easy operation.
[0061] See attached Figure 3 There are various types of spirit levels 51, and one of them is introduced in this embodiment. Specifically, the spirit level 51 uses a ruler-type spirit level 51, and there are two spirit levels 51 and their extension directions intersect with each other.
[0062] Through the design of the above structure, the cross-sectional line of the base 1 passing through the first level 51 can be adjusted to the horizontal plane through the cooperation of the leveling component 52 and the first level 51, and then the cross-sectional line of the base 1 passing through the second level 51 can be adjusted to the horizontal plane through the cooperation of the leveling component 52 and the second level 51. Since the above two cross-sectional lines intersect with each other and are both located in the horizontal plane, it can be determined that the base 1 is also in the horizontal plane.
[0063] See attached Figure 1 -Attached Figure 3 And attached Figure 8 , Attachment Figure 9 There are many structures that can adjust the distance between a certain part of the bottom of the base 1 and the ground. One of them is introduced in this embodiment. Specifically, a plurality of second threaded holes 103 and a plurality of guide holes 104 are provided on the base 1. The second threaded holes 103 and the guide holes 104 correspond to each other one by one and are all vertically arranged. The leveling assembly 52 includes an adjusting bolt 521, a guide rod 522, and a support member 523. The adjusting bolt 521 is engaged in the second threaded hole 103; the guide rod 522 is slidably connected to the guide hole 104; the top of the support member 523 is rotatably connected to the adjusting bolt 521 and fixedly connected to the guide rod 522, and the bottom of the support member 523 abuts the ground for support.
[0064] Through the design of the above structure, by rotating the adjusting bolt 521, the support member 523 and the base 1 can move toward each other along the extension direction of the guide rod 522, thereby changing the distance between the support member 523 and the base 1. Since the support member 523 abuts the ground, the distance between a certain part of the bottom of the base 1 and the ground can be changed in the above manner, so that the base 1 can be adjusted to a horizontal plane in conjunction with the level 51.
[0065] See attached Figure 2 , Attachment Figure 8 and attached Figure 9 In actual use, the ground cannot be absolutely level, and is often uneven or even has a certain slope. If the support member 523 is a plane, it cannot be placed firmly. For example, when the slope is large, the support member 523 with a planar structure is in line contact with the ground, and it is easy to tilt and fall. In order to solve the above problem, the following design is made in this embodiment. Specifically, the support member 523 includes a fixing member 5231 and a tripod bracket 5233. The top of the fixing member 5231 is rotatably connected to the adjusting bolt 521 and fixedly connected to the guide rod 522. The bottom of the fixing member 5231 is embedded with a universal ball 5232; the top of the tripod bracket 5233 is connected to the universal ball 5232, and the bottom is against the ground.
[0066] Through the design of the above structure, no matter what the terrain is, the tripod 5233 can adapt to the ground and abut the ground under the weight of the real estate size registration pole, thereby forming a firm support for the base 1 and other components, preventing the entire real estate size registration pole from tilting and falling.
