[0002] When planning and designing a building, it is usually necessary to measure the walls of the building to ensure that the construction can proceed smoothly. When measuring a building, it is inevitable to encounter irregular curved edges, so it is necessary to measure the irregular curved edges before the later construction can be carried out based on the measurement results.

[0003] In the prior art, most of the building measurement tools have relatively simple functions. Most of them can only realize a specific function. For example, a level can only measure the horizontality of a wall, and a distance meter can only measure the length and width of a wall. Therefore, it is very necessary to provide a tool that can measure the curved edge and the vertical inclination of a wall. Summary of the invention

[0007] According to a further technical solution, the connection unit comprises an electric telescopic rod installed on a connection seat, a telescopic end of the electric telescopic rod is connected to a connection plate, and the connection block is installed on the connection plate.

[0008] According to a further technical solution, the second limiting unit includes a limiting plug, which is slidably installed in a second mounting groove in the connecting block, and the limiting plug is connected to the interior of the second mounting groove through a third spring, and a limiting hole matching the limiting plug is also provided on the detection rod, and an adjustment member for adjusting the position of the limiting plug is also provided in the second mounting groove.

[0009] According to a further technical solution, the adjusting member is an electromagnet.

[0010] According to a further technical solution, a control unit for controlling the on / off state of the adjusting member is also provided in the limit top block; When the limiting top block contacts the inner wall of the mounting seat, the control unit controls the adjusting member to be in a powered-on state; When the limiting top block is not in contact with the inner wall of the mounting seat, the control unit controls the adjusting member to be in a power-off state.

[0011] According to a further technical solution, the control unit includes a pressure block, which is installed in a first mounting groove opened on the limiting top block, and the first mounting groove is opened on a side of the limiting top block close to the outer edge of the rotating disk, the pressure block is connected to the interior of the first mounting groove through a fourth spring, and a push-type switch is also arranged in the first mounting groove.

[0012] An embodiment of the present invention provides a curved edge measuring tool for building planning. When in use, the device has two working states: One is used to detect the vertical inclination of the building wall. Specifically, at this time, the first limit unit is in an inoperative state (that is, the first limit unit does not fix the rotating disk on the mounting seat), and the rotating disk can rotate freely in a vertical plane on the mounting seat.

If the wall is tilted, at this time, by observing the specific degree of the indicator line corresponding to the indicator measurement line, the angle of rotation of the rotating disk can be determined, thereby measuring the overall inclination of the wall. It should be additionally added that in the initial state, the indicator line corresponds to the "0" scale on the measurement line, and the connecting seats are all in a vertical state. The second is to detect the irregular curved edge of the building. Specifically, at this time, the first limiting unit is in working state (that is, the first limiting unit fixes the rotating disk on the mounting seat in the initial state), and the rotating disk cannot rotate. At the same time, the second limiting unit will release the limit on the detection rod, so that the detection rod can slide in the connecting block. At this time, the relative position of the second detection module as a whole is also adjusted by the connecting unit so that the two groups of second detection modules are at a suitable distance, and then the two groups of second detection modules can be abutted against the wall. It should be noted that at this time, only one roller on the detection rod needs to be abutted against the wall, and the second spring close to the wall side is compressed to a certain extent (it can be compressed to a half-way state), and the initial position of the measuring plate is recorded by the displacement sensor. Then the device is moved along the direction of the wall so that the roller moves along the direction of the wall. In this process, affected by the ups and downs of the wall, the roller will push the detection rod to slide in the connecting block, and the detection rod will drive the measuring plate to move synchronously, and the position change of the measuring plate is recorded in real time by the displacement sensor. By combining the data of movement along the wall and the position data recorded by the displacement sensor, the shape of the curved edge of the building can be mapped. The device has various functions and can meet various building inspection needs. It is easy to operate, has a wide range of applications, high work efficiency and good use effect.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1-Figure 5 As shown, a curved edge measuring tool for building planning provided by an embodiment of the present invention includes a mounting base 1, a connecting flange 11 is provided on the side wall of the mounting base 1; and further includes: A first detection module 2, the first detection module 2 comprises a rotating disk 21 rotatably mounted on the mounting seat 1, and the rotating disk 21 is also provided with a first limiting unit 3 for fixing the rotating disk 21 on the mounting seat 1, and the rotating disk 21 is symmetrically provided with connecting seats 22 on the upper and lower sides, and the rotating disk 21 is also provided with a plurality of measuring lines 23, and the mounting seat 1 is also provided with an indicating line 24 for indicating the degree of the measuring line 23; The second detection module 5 is provided with two groups, and the two groups of the second detection modules 5 are symmetrically arranged on the upper and lower sides of the rotating disk 21. The second detection module 5 includes a connecting block 51, each of the connecting blocks 51 is connected to the connecting seat 22 through a group of retractable connecting units 4, a detection rod 52 is slidably installed in the connecting block 51 along the horizontal direction, and the connecting block 51 is also provided with a second limiting unit 6 for fixing the detection rod 52 in the connecting block 51, a roller 56 is rotatably installed at both ends of the detection rod 52, and a measuring plate 53 is also provided at both ends of the detection rod 52, and a second spring 54 is connected between the measuring plate 53 and the connecting block 51, and a displacement sensor 55 for detecting the position change of the measuring plate 53 is also provided on the connecting block 51.

[0018] In the embodiment of the present invention, the mounting base 1 can be connected to a related mobile device in the prior art via the connecting flange 11, thereby driving the entire device to move along a specified path to meet different detection requirements.

[0019] When in use, the device has two working states: One is to detect the vertical inclination of the building wall. Specifically, at this time, the first limiting unit 3 is in an inoperative state (that is, the first limiting unit 3 does not fix the rotating disk 21 on the mounting base 1), and the rotating disk 21 can rotate freely in a vertical plane on the mounting base 1. At the same time, the second limiting unit 6 will fix the detection rod 52 in the connecting block 51, so that the detection rod 52 cannot slide. In addition, it should be mentioned that the sliding direction of the connecting block 51 is perpendicular to the plane of rotation of the rotating disk 21. First, the relative position of the second detection module 5 as a whole is adjusted by the connecting unit 4, so that the two groups of second detection modules 5 are at a suitable distance, and then the two groups of second detection modules 5 can be abutted against the wall, and each roller 56 in the second detection module 5 will contact the wall. If the wall is tilted, at this time, by observing the specific degree of the indicator line 24 corresponding to the indicator measurement line 23, the angle of rotation of the rotating disk 21 can be determined, thereby measuring the overall inclination of the wall. It should be additionally added that, in the initial state, the indicator line 24 corresponds to the “0” mark on the measuring line 23 , and the connecting seat 22 is in a vertical state.

[0020] The second is to detect the irregular curved edge of the building. Specifically, at this time, the first limiting unit 3 is in working state (that is, the first limiting unit 3 fixes the rotating disk 21 on the mounting seat 1 in the initial state), and the rotating disk 21 cannot rotate. At the same time, the second limiting unit 6 will release the limit on the detection rod 52, so that the detection rod 52 can slide in the connecting block 51. At this time, the relative position of the second detection module 5 as a whole is also adjusted by the connecting unit 4, so that the two groups of second detection modules 5 are at a suitable distance, and then the two groups of second detection modules 5 can be abutted against the wall. It should be noted that at this time, only one roller 56 on the detection rod 52 needs to be abutted against the wall, and the second spring 54 on the side close to the wall is compressed to a certain extent (it can be compressed to a half-way state), and the initial position of the measuring plate 53 is recorded by the displacement sensor 55. Then the device is moved along the direction of the wall, so that the roller 56 moves along the direction of the wall. In this process, affected by the fluctuation of the wall surface, the roller 56 will push the detection rod 52 to slide in the connecting block 51, and the detection rod 52 will drive the measuring plate 53 to move synchronously, and the position change of the measuring plate 53 will be recorded in real time through the displacement sensor 55. By combining the data moving along the direction of the wall surface and the position data recorded by the displacement sensor 55, the shape of the curved edge of the building can be measured.

[0021] like Figure 1 and Figure 5 As shown, as a preferred embodiment of the present invention, the first limiting unit 3 includes an adjusting bolt 32 installed on the rotating disk 21, and a limiting cam 31 is sleeved on the adjusting bolt 32. Two guide seats 33 are symmetrically arranged on both sides of the limiting cam 31. A push rod 34 is installed in the guide seat 33 along the radial sliding direction of the rotating disk 21, and a first spring 36 is arranged between the guide seat 33 and the push rod 34. A limiting top block 35 is arranged at one end of the push rod 34 close to the outer edge of the rotating disk 21.

[0022] In the embodiment of the present invention, when no external force is applied, the elastic force of the first spring 36 causes the push rod 34 to move toward the side close to the center of the rotating disk 21, and causes the end of the push rod 34 close to the center of the rotating disk 21 to always abut against the edge of the limit cam 31. When the rotating disk 21 is to be able to rotate freely, it is only necessary to make the small end of the limit cam 31 abut against the ends of the two push rods 34, and at this time, the limit top block 35 does not contact the mounting seat 1. When the position of the rotating disk 21 is to be fixed, it is only necessary to rotate the adjusting bolt 32, and the adjusting bolt 32 can drive the limit cam 31 to rotate, so that the large end of the adjusting bolt 32 abuts against the end of the push rod 34, thereby pushing the push rod 34 to slide toward the side away from the center of the rotating disk 21, and the push rod 34 can push the limit top block 35 to abut against the inner ring of the mounting seat 1, thereby fixing the rotating disk 21.

[0023] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, the connecting unit 4 includes an electric telescopic rod 41 installed on the connecting seat 22, the telescopic end of the electric telescopic rod 41 is connected to a connecting plate 42, and the connecting block 51 is installed on the connecting plate 42.

[0024] In the embodiment of the present invention, when in use, it is only necessary to control the electric telescopic rod 41 to extend and retract, and the electric telescopic rod 41 can drive the connecting block 51 to move synchronously through the connecting plate 42, so as to adjust the distance between the second detection module 5 and the rotating disk 21. By controlling the two groups of connecting units 4 to extend and retract at the same time, the distance between the two groups of second detection modules 5 can be adjusted, so that the two groups of second detection modules 5 can contact positions at different heights on the building wall at the same time, which can be used to detect the inclination between different positions on the building wall, and can also measure the curved edges at different heights at the same time.

[0025] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the second limiting unit 6 includes a limiting plug 61, and the limiting plug 61 is slidably installed in the second mounting groove 511 opened in the connecting block 51, and the limiting plug 61 is connected to the inside of the second mounting groove 511 through a third spring 62, and a limiting hole 521 matching the limiting plug 61 is also opened on the detection rod 52, and an adjusting member 63 for adjusting the position of the limiting plug 61 is also provided in the second mounting groove 511.

[0026] In an embodiment of the present invention, the adjusting member 63 is an electromagnet. When in use, the position of the limit plug 61 can be adjusted by controlling the power on and off state of the adjusting member 63. When the adjusting member 63 is in the power-on state, the magnetic attraction of the adjusting member 63 will cause the limit plug 61 to be completely retracted into the second mounting groove 511, and the detection rod 52 can slide freely in the connecting block 51. When the adjusting member 63 is in the power-off state, the elastic force of the third spring 62 will push a part of the limit plug 61 to be inserted into the limit plug hole 521, so that the detection rod 52 is fixed in the connecting block 51 and cannot slide.

[0027] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the limit top block 35 is further provided with a control unit 7 for controlling the on / off state of the regulating member 63; When the limiting top block 35 contacts the inner wall of the mounting seat 1, the control unit 7 controls the adjusting member 63 to be in a powered state; When the limiting top block 35 is not in contact with the inner wall of the mounting base 1 , the control unit 7 controls the adjusting member 63 to be in a power-off state.

[0028] In the embodiment of the present invention, the power-on and power-off states of the adjusting member 63 are controlled by the control unit 7, which can be used to meet different detection functions. Specifically, when the limit top block 35 contacts the inner wall of the mounting base 1, the rotating disk 21 is fixed and can no longer rotate. At this time, the control unit 7 controls the adjusting member 63 to be in the power-on state, so that the detection rod 52 can slide freely in the connecting block 51, which can be used to detect the curved edge undulation state of the building wall.

[0029] When the limiting top block 35 is not in contact with the inner wall of the mounting base 1, the rotating disk 21 can rotate freely on the mounting base 1, and the control unit 7 controls the adjusting member 63 to be in a power-off state, so that the detection rod 52 can be fixed in the connecting block 51. At this time, the vertical inclination of the wall can be detected through the cooperation of the upper and lower sets of second detection modules 5.

[0030] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the control unit 7 includes a pressure block 71, and the pressure block 71 is installed in a first mounting groove 351 opened on the limiting top block 35, and the first mounting groove 351 is opened on the side of the limiting top block 35 close to the outer edge of the rotating disk 21, the pressure block 71 is connected to the inside of the first mounting groove 351 through a fourth spring 72, and a push-type switch 73 is also provided in the first mounting groove 351.

[0031] In the embodiment of the present invention, when no external force is applied, the elastic force of the fourth spring 72 causes a portion of the pressing block 71 to extend out of the limit top block 35, and at this time, the pressing block 71 does not contact the push switch 73, and the push switch 73 cannot control the power supply of the adjusting member 63. As the limit top block 35 slides toward the side close to the inner wall of the mounting seat 1 until the limit top block 35 is tightly pressed against the inner wall of the mounting seat 1, the pressing block 71 will be pressed into the first mounting groove 351, and the pressing block 71 will contact and press the push switch 73, thereby controlling the power supply of the adjusting member 63 through the push switch 73.

[0032] Working principle: When in use, when the vertical inclination of the building wall is to be detected. At this time, the small end of the limit cam 31 abuts against the ends of the two push rods 34, the limit top block 35 does not contact the inner ring of the mounting seat 1, and the rotating disk 21 can rotate freely in a vertical plane on the mounting seat 1. At the same time, the elastic force of the fourth spring 72 will cause a part of the pressure block 71 to extend to the outside of the limit top block 35, and at this time the pressure block 71 does not contact the push switch 73, and the push switch 73 cannot control the adjustment member 63 to be energized. When the adjustment member 63 is in the power-off state, the elastic force of the third spring 62 will push a part of the limit plug 61 to be inserted into the limit plug 521, so that the detection rod 52 is fixed in the connection block 51 and cannot slide. In addition, it should be mentioned that the sliding direction of the connection block 51 is perpendicular to the plane of rotation of the rotating disk 21. First, the relative position of the second detection module 5 as a whole is adjusted by the connection unit 4 so that the two groups of second detection modules 5 are at a suitable distance, and then the two groups of second detection modules 5 can be placed against the wall, and each roller 56 in the second detection module 5 will contact the wall. If the wall is tilted, the angle of rotation of the rotating disk 21 can be determined by observing the specific degree of the indicator line 24 corresponding to the indicator measuring line 23, thereby measuring the overall inclination of the wall. It should be additionally supplemented that, in the initial state, the indicator line 24 corresponds to the "0" scale on the measuring line 23, and the connecting seat 22 is in a vertical state.

[0033] When the irregular curved edge of the building is to be detected, the rotating disk 21 needs to be fixed on the mounting base 1 in the initial state through the first limiting unit 3. Specifically, it is only necessary to rotate the adjusting bolt 32, and the adjusting bolt 32 can drive the limiting cam 31 to rotate, so that the large end of the adjusting bolt 32 abuts against the end of the push rod 34, thereby pushing the push rod 34 to slide to the side away from the center of the circle of the rotating disk 21, and the push rod 34 can push the limiting top block 35 to abut against the inner ring of the mounting base 1, thereby fixing the rotating disk 21. When the limiting top block 35 abuts against the inner wall of the mounting base 1, the pressing block 71 will be pressed into the first mounting groove 351, and the pressing block 71 will abut against the push switch 73 and press the push switch 73, so that the adjusting member 63 is controlled to be energized through the push switch 73. When the adjusting member 63 is in the power-on state, the magnetic attraction of the adjusting member 63 will make the limiting plug 61 completely retract into the second installation groove 511, and the detection rod 52 can slide freely in the connecting block 51. Then, the relative position of the second detection module 5 as a whole is adjusted by the connecting unit 4 so that the two groups of second detection modules 5 are at a suitable distance, and then the two groups of second detection modules 5 can be abutted against the wall. It should be noted that at this time, only one roller 56 on the detection rod 52 needs to be abutted against the wall, and the second spring 54 close to the wall side is compressed to a certain extent (can be compressed to a half-way state), and the initial position of the measuring plate 53 is recorded by the displacement sensor 55. Then, the device is moved along the direction of the wall so that the roller 56 moves along the direction of the wall. In this process, after being affected by the ups and downs of the wall, the roller 56 will push the detection rod 52 to slide in the connecting block 51, and the detection rod 52 will drive the measuring plate 53 to move synchronously, and the position change of the measuring plate 53 is recorded in real time by the displacement sensor 55. By combining the data of movement along the direction of the wall and the position data recorded by the displacement sensor 55, the shape of the curved edge of the building can be mapped.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
