Description

Technical Field

[0001] This utility model relates to the field of real estate measurement technology, and in particular to a high-precision real estate area measuring instrument. Background Technology

[0002] Land surveying is the work of measuring and mapping the topographic distribution and quantity of various types of land using surveying and remote sensing technologies. Land surveying is an important part of land management and includes cadastral surveying, topographic surveying, land use status surveying, land flatness surveying, and surveys of reserve land resources such as barren hills and wastelands.

[0003] Currently, when measuring land area or length, the traditional method of measuring with a tape measure often requires two workers to coordinate and work together. However, this method is labor-intensive and can easily cause the tape measure to deviate during measurement, making it difficult to achieve accurate measurements. Therefore, we propose a high-precision real estate area measuring instrument to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where traditional measuring methods require two workers to coordinate and use a tape measure, and the tape measure is prone to shifting. Therefore, this invention proposes a high-precision real estate area measuring instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision real estate area measuring instrument includes a support rod, a support ring fixedly installed at the bottom end of the support rod, a handle fixedly installed at the top end of the support rod, a rotating shaft rotatably connected through the support ring, and a roller fixedly sleeved on the rotating shaft. The measuring instrument also includes...

[0007] The measuring mechanism passes through and is connected to the support rod, and the bottom of the measuring mechanism is connected to one end of the rotating shaft.

[0008] The transmission mechanism is connected to the measuring mechanism and the other end of the rotating shaft respectively. The transmission mechanism is used to transmit the rotational power of the rotating shaft to the measuring mechanism, so that the measuring mechanism can operate.

[0009] The marking mechanism is located on one side of the support rod. The marking mechanism is used to mark the path of the roller during its movement.

[0010] In one possible design, the measuring mechanism includes a first winding wheel and a second winding wheel. The first winding wheel is fixedly mounted on one end of a rotating shaft. A connecting shaft is rotatably connected through a support rod. The second winding wheel is fixedly mounted on one end of the connecting shaft. The same measuring tape is wound around the first and second winding wheels. A sliding hole is provided on the support rod. A positioning component is installed on one side of the second winding wheel. One side of the positioning component passes through the sliding hole and extends to one side of the support rod. The positioning component is connected to one side of the support rod.

[0011] In one possible design, the positioning component includes a retaining ring fixedly installed on one side of the second reel, with multiple slots evenly spaced on the retaining ring, a push plate slidably connected through the sliding hole, and a retaining shaft fixedly installed on one side of the push plate, the retaining shaft being movably engaged with the multiple slots respectively.

[0012] In one possible design, a slide rod is slidably connected through the push plate to one side of the support rod. The slide rod is fixedly connected to one side of the support rod. A first magnet ring is fixedly installed at the bottom of the push plate, and a second magnet ring is fixedly installed at the bottom end of the slide rod. The sides of the first magnet ring and the second magnet ring that are close to each other are respectively set as N pole and S pole, and the first magnet ring and the second magnet ring attract each other.

[0013] In one possible design, the transmission mechanism includes two synchronous pulleys, which are respectively fixedly mounted on the other end of the rotating shaft and the other end of the connecting shaft, and the same synchronous belt is driven onto the two synchronous pulleys.

[0014] In one possible design, the marking mechanism includes a base plate with a mounting cover fixedly mounted on the top of the base plate. An adjustment assembly is installed inside the mounting cover, with one side of the adjustment assembly extending to the outside of the mounting cover and equipped with a laser light, and the top of the adjustment assembly extending above the mounting cover.

[0015] In one possible design, the adjustment assembly includes a screw rotatably connected to the inner wall of the bottom of the mounting cover, a movable plate slidably connected inside the mounting cover, a nut fixedly mounted on the top of the movable plate, one side of the movable plate extending to the outside of the mounting cover and fixedly connected to the laser lamp, the top end of the screw penetrating the movable plate, the nut and the inner wall of the top of the mounting cover and extending to the top of the mounting cover, and the screw and the nut being threadedly connected.

[0016] In one possible design, two anchor rods are symmetrically and slidably connected through the base plate, and the top ends of the two anchor rods are fixedly installed with the same pull plate.

[0017] In this application, the base plate is first pre-set at the starting point of the land survey. Then, the pull plate is pushed downwards, causing two anchor rods to move downwards, thus inserting the anchor rods into the soil and positioning the base plate. This provides a stable limit for the laser light. Then, rotating the screw, through the threaded transmission with the nut, causes the moving plate to move longitudinally, allowing for height adjustment of the laser light. This allows for adjustment of the laser light's height according to different terrain conditions during practical applications. After adjusting the laser light's position, the laser light is powered on. Then, the handle is used to push the roller along the straight line of light emitted by the laser light. When the measuring tape is wound around the first roller, it can drive the shaft to rotate. With the transmission cooperation of the two synchronous pulleys and the synchronous belt, it can drive the connecting shaft to rotate. At this time, the first roller and the second roller can rotate synchronously, so that the measuring tape located on the second roller can be wound around the first roller. As the measuring tape is wound, the scale lines set on it can measure the distance of the roller movement. Therefore, when the roller is pushed to roll on the ground, it can be convenient to measure the length of the ground. When the support rod is pulled to make the roller rotate in the opposite direction, it can drive the shaft to rotate in the opposite direction, so that the first roller and the second roller can rotate in the opposite direction, thereby winding the measuring tape onto the second roller.

[0018] When not in use, the push plate can be pushed to push the clamping shaft into the corresponding slot. At the same time, the first and second magnetic rings are in an attracted state, which can limit and brake the push plate, so that the clamping shaft is stably clamped to the slot. This can brake and limit the second winding wheel. At this time, the first winding wheel can be limited by the tape measure.

[0019] Beneficial effects: In this utility model, the high-precision real estate area measuring instrument, through the measuring scale mechanism, can push the support rod to make the roller roll on the ground, which can drive the rotating shaft to rotate. When the rotating shaft rotates, it can drive the first winding wheel to rotate, so that the tape measure located on the second winding wheel can be wound around the first winding wheel. As the tape measure is wound, the scale lines set on it can measure the distance of the roller movement. Therefore, when pushing the roller to roll on the ground, it can conveniently measure the length of the ground.

[0020] In this utility model, the high-precision real estate area measuring instrument, through a transmission mechanism, can drive the connecting shaft to rotate when the rotating shaft rotates with the rollers, under the transmission cooperation of two synchronous pulleys and a synchronous belt. Therefore, it can realize the unwinding of the measuring tape from the second roller, and when the support rod is pulled to make the rollers rotate in the opposite direction, it can drive the rotating shaft to rotate in the opposite direction, thereby making the first roller and the second roller rotate in the opposite direction, so as to rewind the measuring tape onto the second roller.

[0021] In this utility model, the high-precision real estate area measuring instrument, through the marking mechanism, can, after the base plate is pre-set at the starting point of land measurement, adjust the position of the laser lamp and then power on the laser lamp. At this time, the straight light emitted by the laser lamp can form a reference for the movement of the roller, so that the roller can maintain a straight line during the movement, thereby enabling accurate measurement of the size of the land.

[0022] This invention allows for convenient measurement of the length and distance of the ground by pre-setting a laser light at the starting point of land measurement and then moving a roller. Therefore, it is convenient for one person to perform the measurement. At the same time, with the light emitted by the laser light as a reference, the roller can be kept moving in a straight line, thereby ensuring the accuracy of the land measurement.

The positioning component includes a retaining ring 12 fixedly mounted on one side of the second winding wheel 7, with multiple equally spaced retaining slots 13 on the retaining ring 12. A push plate 15 is slidably connected through the sliding hole 19. A slide rod 14 located on one side of the support rod 1 is slidably connected through the push plate 15. The slide rod 14 is fixedly connected to one side of the support rod 1. A retaining shaft 16 is fixedly installed on one side of the push plate 15, and the retaining shaft 16 is movably engaged with multiple retaining slots 13. A first magnet ring 17 is fixedly installed at the bottom of the push plate 15, and a second magnet ring 18 is fixedly installed at the bottom end of the slide rod 14. The sides of the first magnet ring 17 and the second magnet ring 18 that are close to each other are respectively set as N pole and S pole, and the first magnet ring 17 and the second magnet ring 18 attract each other.

[0032] A transmission mechanism, connected to both the measuring mechanism and the other end of the rotating shaft 3, transmits the rotational power of the rotating shaft 3 to the measuring mechanism, enabling the measuring mechanism to operate. The transmission mechanism includes two synchronous pulleys 9, which are fixedly mounted on the other end of the rotating shaft 3 and the other end of the connecting shaft 6, respectively. The same synchronous belt 10 is fitted onto the two synchronous pulleys 9.

[0033] This application can be used in the field of real estate surveying technology, or in other fields applicable to this application.

[0034] Example 2: Reference Figure 5Based on Embodiment 1, an improvement is made to a high-precision real estate area measuring instrument, which is applied to the field of real estate measurement technology. A marking mechanism, located on one side of the support rod 1, is used to mark the path of the roller 4 during its movement. The marking mechanism includes a base plate 20, with a mounting cover 21 fixedly installed on the top of the base plate 20. An adjustment assembly is installed inside the mounting cover 21, with one side extending to the outside of the mounting cover 21 and housing a laser light 24. The top of the adjustment assembly extends above the mounting cover 21. The adjustment assembly includes a screw 22 rotatably connected to the inner wall of the bottom of the mounting cover 21. A movable plate 23 is slidably connected inside the mounting cover 21, with a nut 25 fixedly installed on the top of the movable plate 23. One side of the movable plate 23 extends to the outside of the mounting cover 21 and is fixedly connected to the laser light 24. The top end of the screw 22 passes through the movable plate 23, the nut 25, and the top inner wall of the mounting cover 21, extending above the mounting cover 21. The screw 22 is threadedly connected to the nut 25. Two anchor rods 27 are symmetrically and slidingly connected on the base plate 20, and the top of the two anchor rods 27 are fixedly installed with the same pull plate 26.

[0035] In practical use, firstly, the base plate 20 is set at the starting point of the land survey, and the height and position of the laser lamp 24 are adjusted so that the straight line light emitted by the laser lamp 24 forms a reference for the movement of the roller 4. Then, the laser lamp 24 is powered on, and the straight line light emitted by the laser lamp 24 can form a reference for the movement of the roller 4, so that the roller 4 can maintain a straight line during its movement. Next, the pull plate 26 is pushed down to move the two anchor rods 27 downward, inserting the anchor rods 27 into the soil to position the base plate 20, thereby stably limiting the laser lamp 24. Then, the support rod 1 is pushed to make the roller 4 roll on the ground, which can drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it can drive the first winding wheel 5 to rotate, so that the measuring tape 8 located on the second winding wheel 7 can be wound around the first winding wheel 5. As the measuring tape 8 is wound, the scale lines set on it can measure the distance moved by the roller 4. When braking and limiting are required, push the push plate 15 to push the clamping shaft 16 into the corresponding bayonet 13, thus braking and limiting the second winding wheel 7. At this time, under the attraction of the first magnetic ring 17 and the second magnetic ring 18, the push plate 15 can be limited and braked, so that the clamping shaft 16 and the bayonet 13 are stably clamped. At the same time, when the rotating shaft 3 rotates with the roller 4, it can drive the connecting shaft 6 to rotate under the transmission cooperation of the two synchronous pulleys 9 and the synchronous belt 10, so as to unwind the tape measure 8 from the second winding wheel 7. When the support rod 1 is pulled to make the roller 4 rotate in the opposite direction, it can drive the rotating shaft 3 to rotate in the opposite direction, so that the first winding wheel 5 and the second winding wheel 7 rotate in the opposite direction, and the tape measure 8 is wound onto the second winding wheel 7.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of the laser lamp 24 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
