Description

Technical Field

[0001] The invention belongs to the technical field of building planning, and in particular relates to a curved edge measuring tool for building planning. Background Art

[0002] When planning and designing a building, it is often necessary to measure the building's walls to ensure smooth construction. During building measurement, irregular curved edges are unavoidable, so these edges need to be measured before subsequent construction can proceed based on the measurement results.

[0003] In existing technologies, architectural measurement tools are often limited to a single function. For example, a level can only measure the levelness of a wall, while a distance meter can only measure the length and width of a wall. Therefore, it is crucial to provide a tool that can measure both curved edges and the vertical inclination of a wall. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a curved edge measurement tool for architectural planning, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The embodiment of the present invention is implemented as follows: a curved edge measuring tool for architectural planning includes a mounting base, a connecting flange provided on a side wall of the mounting base; and further includes:

[0006] A first detection module, comprising a rotating disk rotatably mounted on a mounting base, the rotating disk further being provided with a first limiting unit for fixing the rotating disk to the mounting base, connecting bases being symmetrically provided on upper and lower sides of the rotating disk, the rotating disk further being provided with a plurality of measuring lines, and the mounting base further being provided with an indicator line for indicating the degree of the measuring lines;

[0007] The second detection module is provided with two groups, and the two groups of the second detection modules are symmetrically arranged on the upper and lower sides of the rotating disk. The second detection module includes a connecting block, each of the connecting blocks is connected to the connecting seat through a group of retractable connecting units, a detection rod is installed in the connecting block along the horizontal direction, and the connecting block is also provided with a second limiting unit for fixing the detection rod in the connecting block, a roller is rotatably installed at both ends of the detection rod, and a measuring plate is also provided at both ends of the detection rod, and a second spring is connected between the measuring plate and the connecting block, and a displacement sensor for detecting the position change of the measuring plate is also provided on the connecting block.

[0008] A further technical solution is that the first limiting unit includes an adjusting bolt installed on the rotating disk, a limiting cam is sleeved on the adjusting bolt, two guide seats are symmetrically provided on both sides of the limiting cam, a push rod is installed in the guide seat for radial sliding along the rotating disk, and a first spring is provided between the guide seat and the push rod, and a limiting top block is provided at one end of the push rod close to the outer edge of the rotating disk.

[0009] According to a further technical solution, the connecting unit includes an electric telescopic rod installed on the connecting seat, the telescopic end of the electric telescopic rod is connected to a connecting plate, and the connecting block is installed on the connecting plate.

[0010] A further technical solution is that the second limiting unit includes a limiting plug, which is slidably installed in a second mounting groove opened in the connecting block, and the limiting plug is connected to the interior of the second mounting groove through a third spring. A limiting hole matching the limiting plug is also opened on the detection rod, and an adjustment member for adjusting the position of the limiting plug is also provided in the second mounting groove.

[0011] According to a further technical solution, the adjusting member is an electromagnet.

[0012] According to a further technical solution, the limit top block is further provided with a control unit for controlling the on / off state of the regulating member;

[0013] When the limiting top block contacts the inner wall of the mounting seat, the control unit controls the adjusting member to be in a power-on state;

[0014] 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.

[0015] A further technical solution is that 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 the 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 provided in the first mounting groove.

[0016] An embodiment of the present invention provides a curved edge measurement tool for architectural planning. When in use, the device has two working states:

[0017] One method is to detect the vertical inclination of a building wall. Specifically, when the first limiting unit is inactive (i.e., the first limiting unit does not secure the rotating disk to the mounting base), the rotating disk can rotate freely within a vertical plane on the mounting base. Simultaneously, the second limiting unit secures the detection rod in the connecting block, preventing it from sliding. It is also important to note that the sliding direction of the connecting block is perpendicular to the plane of rotation of the rotating disk. The relative positions of the second detection modules are first adjusted using the connecting unit to ensure an appropriate spacing between the two sets of second detection modules. The two sets of second detection modules are then placed against the wall, and the rollers in the second detection modules come into contact with the wall. If the wall is tilted, the angle of rotation of the rotating disk can be determined by observing the specific degree of the indicator line corresponding to the indicator scale line, thereby measuring the overall inclination of the wall. It should be noted that in the initial state, the indicator line corresponds to the "0" mark on the scale line, and the connecting base is in a vertical position. The second method is used to detect irregular curved edges of buildings. Specifically, the first limiting unit is in operation (i.e., it secures the rotating disk to its initial position on the mounting base), preventing it from rotating. Simultaneously, the second limiting unit releases the detection rod's restraint, allowing it to slide within the connecting block. Again, the connecting unit is used to adjust the relative position of the second detection modules, ensuring an appropriate spacing between the two sets. The two sets can then be placed against the wall. It's important to note that in this case, only one roller on the detection rod needs to be placed against the wall. The second spring on the wall side is compressed to a certain degree (perhaps halfway), and the initial position of the detection plate is recorded using a displacement sensor. The device is then moved along the wall, causing the roller to move along the wall. During this process, the roller pushes the detection rod to slide within the connecting block, influenced by the undulations of the wall. This in turn drives the detection plate to move synchronously, with the displacement sensor recording the position changes in real time. By combining data collected along the wall's path with position data recorded by the displacement sensor, the shape of the building's curved edges can be mapped. The device is versatile and can meet a variety of building inspection needs. It offers simple operation, a wide range of applications, high efficiency, and excellent results.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] like Figure 1-Figure 5 As shown, a curved edge measuring tool for building planning provided by one 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:

[0028] A first detection module 2 includes a rotating disk 21 rotatably mounted on the mounting base 1, and the rotating disk 21 is further provided with a first limiting unit 3 for fixing the rotating disk 21 on the mounting base 1. Connecting seats 22 are symmetrically provided on the upper and lower sides of the rotating disk 21. The rotating disk 21 is further provided with a plurality of measuring lines 23, and the mounting base 1 is further provided with an indicator line 24 for indicating the degree of the measuring lines 23;

[0029] 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, and 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 installed in the connecting block 51 in a horizontal sliding 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. A displacement sensor 55 for detecting the position change of the measuring plate 53 is also provided on the connecting block 51.

[0030] 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.

[0031] When in use, the device has two working states:

[0032] One method is to detect the vertical inclination of a building wall. Specifically, when the first limiting unit 3 is in the inactive state (i.e., the first limiting unit 3 does not secure the rotating disk 21 to the mounting base 1), the rotating disk 21 can rotate freely within a vertical plane on the mounting base 1. Simultaneously, the second limiting unit 6 secures the detection rod 52 within the connecting block 51, preventing it from sliding. Furthermore, it should be noted that the sliding direction of the connecting block 51 is perpendicular to the plane in which the rotating disk 21 rotates. First, the relative position of the second detection modules 5 is adjusted using the connecting unit 4 to ensure an appropriate spacing between the two sets of second detection modules 5. Then, the two sets of second detection modules 5 are placed against the wall, and the rollers 56 in the second detection modules 5 come into contact with 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 measurement line 23, 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 base 22 is in a vertical state.

[0033] The second method is to detect irregular curved edges of buildings. Specifically, the first limiting unit 3 is in operation (i.e., it secures the rotating disk 21 to the mounting base 1 in its initial position), preventing the rotating disk 21 from rotating. Simultaneously, the second limiting unit 6 releases the restraint on the detection rod 52, allowing it to slide within the connecting block 51. At this point, the connecting unit 4 is used to adjust the relative position of the second detection modules 5, ensuring an appropriate spacing between the two sets of second detection modules 5. The two sets of second detection modules 5 can then be placed against the wall. It should be noted that only one roller 56 on the detection rod 52 needs to be placed against the wall. The second spring 54 on the side closest to the wall is compressed to a certain degree (perhaps halfway), and the initial position of the detection plate 53 is recorded by the displacement sensor 55. The device is then moved along the wall, causing the roller 56 to move along the wall. During this process, affected by the undulations of the wall, roller 56 pushes detection rod 52 to slide within connecting block 51. This in turn causes detection plate 53 to move synchronously, with displacement sensor 55 recording the position changes of detection plate 53 in real time. By combining the movement data along the wall with the position data recorded by displacement sensor 55, the shape of the building's curved edge can be mapped.

[0034] 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 provided on both sides of the limiting cam 31. A push rod 34 is installed in the guide seat 33 for radial sliding along the rotating disk 21, and a first spring 36 is provided between the guide seat 33 and the push rod 34. A limiting top block 35 is provided at one end of the push rod 34 close to the outer edge of the rotating disk 21.

[0035] 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 closer to the center of the rotating disk 21, and causes the end of the push rod 34 closer 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 allowed 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. At this time, the limit block 35 does not contact the mounting base 1. When the position of the rotating disk 21 is to be fixed, it is only necessary to rotate the adjusting bolt 32. 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. The push rod 34 can then push the limit block 35 to tightly abut against the inner ring of the mounting base 1, thereby fixing the rotating disk 21.

[0036] 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 the connecting plate 42, and the connecting block 51 is installed on the connecting plate 42.

[0037] In this embodiment of the present invention, during use, it is only necessary to control the electric telescopic rod 41 to extend and retract. The electric telescopic rod 41 can drive the connecting block 51 to move synchronously via the connecting plate 42, thereby adjusting the distance between the second detection module 5 and the rotating disk 21. By simultaneously controlling the two sets of connecting units 4 to extend and retract, the spacing between the two sets of second detection modules 5 can be adjusted, so that the two sets of second detection modules 5 can simultaneously contact locations at different heights on the building wall. This can be used to detect the inclination of different locations on the building wall, and can also simultaneously measure curved edges at different heights.

[0038] 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, which 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. 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.

[0039] In an embodiment of the present invention, the adjusting member 63 is an electromagnet. During use, the position of the limiting plug 61 can be adjusted by simply 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 causes the limiting plug 61 to be completely retracted into the second mounting groove 511, and the detection rod 52 can now 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 pushes a portion of the limiting plug 61 into the limiting socket 521, thereby fixing the detection rod 52 in the connecting block 51 and preventing it from sliding.

[0040] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the limiting top block 35 is further provided with a control unit 7 for controlling the on / off state of the regulating member 63;

[0041] When the limiting top block 35 contacts the inner wall of the mounting base 1, the control unit 7 controls the adjusting member 63 to be in the energized state;

[0042] 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.

[0043] In this embodiment of the present invention, the control unit 7 controls the on / off state of the adjustment member 63 to meet various detection functions. Specifically, when the limiting top block 35 contacts the inner wall of the mounting base 1, the rotating disk 21 is fixed and cannot rotate. At this time, the control unit 7 controls the adjustment member 63 to be in the energized state, allowing the detection rod 52 to slide freely within the connecting block 51, thereby enabling detection of the curved and undulating state of the building wall surface.

[0044] 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 adjustment member 63 to be in the 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.

[0045] 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, which 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, and 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.

[0046] 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 pressure block 71 to extend outside the limit block 35. At this time, the pressure block 71 does not contact the push switch 73, and the push switch 73 cannot control the power supply of the adjustment member 63. As the limit block 35 slides toward the side closer to the inner wall of the mounting base 1 until the limit block 35 and the inner wall of the mounting base 1 are tightly abutted, the pressure block 71 is pressed into the first mounting groove 351, and the pressure block 71 abuts against the push switch 73, pressing the push switch 73, thereby controlling the power supply of the adjustment member 63 through the push switch 73.

[0047] 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 base 1, and the rotating disk 21 can rotate freely in a vertical plane on the mounting base 1. At the same time, the elastic force of the fourth spring 72 will cause a part of the pressure block 71 to extend outside 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 into the limit socket 521, so that the detection rod 52 is fixed in the connecting block 51 and 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, use the connecting unit 4 to adjust the relative position of the second detection modules 5 so that the two sets of second detection modules 5 are spaced appropriately apart. Then, place the two sets of second detection modules 5 against the wall, bringing the rollers 56 of the second detection modules 5 into contact with 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 noted that, in the initial state, the indicator line 24 corresponds to the "0" mark on the measuring line 23, and the connecting base 22 is in a vertical position.

[0048] When inspecting irregular curved edges of a building, the rotating disk 21 needs to be fixed to the mounting base 1 in its initial state via the first limiting unit 3. Specifically, simply rotating the adjusting bolt 32 will cause the limiting cam 31 to rotate, causing the large end of the adjusting bolt 32 to abut 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. The push rod 34 then pushes the limiting top block 35 to abut against the inner ring of the mounting base 1, thereby securing the rotating disk 21. When the limiting top block 35 abuts against the inner wall of the mounting base 1, the pressure block 71 is pressed into the first mounting groove 351. The pressure block 71 abuts against the push switch 73 and presses the push switch 73, thereby controlling the power supply of the adjusting member 63 via the push switch 73. When the adjustment member 63 is energized, its magnetic attraction causes the stopper 61 to fully retract into the second mounting slot 511, allowing the detection rod 52 to slide freely within the connecting block 51. Similarly, the relative position of the second detection modules 5 is adjusted using the connecting unit 4, ensuring an appropriate spacing between the two sets of second detection modules 5. The two sets of second detection modules 5 can then be placed against the wall. It should be noted that at this point, only one roller 56 on the detection rod 52 needs to be placed against the wall. The second spring 54 on the wall side is compressed to a certain degree (possibly halfway), and the initial position of the detection plate 53 is recorded by the displacement sensor 55. The device is then moved along the wall, causing the roller 56 to move along the wall. During this process, affected by the undulations of the wall, the roller 56 pushes the detection rod 52 to slide within the connecting block 51, causing the detection rod 52 to move synchronously with the detection plate 53, with the displacement sensor 55 recording the position changes of the detection plate 53 in real time. 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.

[0049] 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 scope of protection of the present invention.
