DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figure 1-4 As shown, a building wall angle measuring device described in an embodiment of the present invention includes a measuring mechanism 1, and the measuring mechanism 1 includes: a main seat 11; a slide plate 12 slidably arranged inside the main seat 11; a rotating shaft 13 rotatably connected to the end of the slide plate 12; a movable plate 14 fixedly connected to the rotating shaft 13, and the main seat 11 and the slide plate 12 are both provided with an open groove for the movable plate 14 to rotate; an angle sensor 15 arranged on the slide plate 12 for detecting the rotation angle of the rotating shaft 13.

[0035] Specifically, the slide plate 12 is arranged parallel to the side wall of the main seat 11. Figure 1For example, the slide plate 12 can slide back and forth along the Z axis relative to the main seat 11, and the movable plate 14 can rotate in the XZ plane. The angle sensor 15 is preferably but not limited to a magnetic encoder for measuring the rotation angle. The movable plate 14 is provided with a display screen 16 for displaying the detection data of the angle sensor 15. The movable plate 14 is provided with a lifting hole. The staff can insert their fingers into the lifting hole and then pull the movable plate 14 to rotate the movable plate 14 out of the slide plate 12; initially, the movable plate 14 and the slide plate 12 are closed, and the angle between the two is 0.

[0036] When measuring the angle between the connected wall A and wall B, the main seat 11 is attached to the wall A so that the slide plate 12 in the main seat 11 is parallel to the wall A. It should be noted that when the main seat 11 is placed, the end of the main seat 11 is as close to the connection between the two walls as possible; the movable plate 14 is rotated and the slide plate 12 is slid until the movable plate 14 is attached to the wall B so that the movable plate 14 is parallel to the wall B. In this way, the slide plate 12 and the movable plate 14 are parallel to the two walls respectively, and the angle between the slide plate 12 and the movable plate 14 is the angle between the two walls. The angle of rotation of the rotating shaft 13 is detected by the angle sensor 15, and the display screen 16 is observed to directly obtain the angle data between the two walls, eliminating the trouble of removing the measuring device and then using a protractor or other device for measurement. The operation is quick and the work efficiency is high. It is suitable for measuring the angles of connected walls with acute angles, right angles and obtuse angles, and has good applicability.

[0037] like Figure 1-2 As shown, the measuring mechanism 1 further comprises abutment plates 17 respectively arranged on the main seat 11 and the movable plate 14 , and the two abutment plates 17 are respectively located on the back side of the main seat 11 and the movable plate 14 .

[0038] Specifically, Figure 2 As shown, the slide plate 12 is parallel to the left end wall of the abutment plate 17 on the main seat 11, and the movable plate 14 is parallel to the back wall of the abutment plate 17 arranged on the back of the movable plate 14. The existence of the abutment plate 17 allows the main seat 11 and the movable plate 14 to be normally attached to the two walls respectively when the rotating shaft 13 is away from the connection between the two walls, so as to ensure the normal progress of the measurement work.

[0039] like Figure 3 As shown, a slide groove for placing the movable plate 14 is provided in the slide plate 12 , and an origin limiting block 121 for limiting the movable plate 14 is provided in the slide groove.

[0040] Specifically, the origin limit block 121 is used to determine the initial position of the movable plate 14. When the movable plate 14 is rotated and retracted inside the slide plate 12, after the movable plate 14 is in contact with the origin limit block 121, the angle between the movable plate 14 and the slide plate 12 is 0, and the movable plate 14 is at the origin position.

[0041] like Figure 2-8 As shown, it also includes a positioning mechanism 2, which includes: a first magnetic conductive member 21 arranged inside the movable plate 14, the first magnetic conductive member 21 includes a cylindrical section and a flat plate end, the cylindrical section is coaxial with the rotating shaft 13, and the end of the cylindrical section extends to the outside of the rotating shaft 13; a second magnetic conductive member 22 arranged on the side wall of the slide plate 12, the second magnetic conductive member 22 is connected to the first magnetic conductive member 21; a magnetic conductive plate 23 arranged inside the main seat 11, the magnetic conductive plate 23 is located on the side where the first magnetic conductive member 21 and the second magnetic conductive member 22 are located; a magnetic block 24 slidingly arranged inside the movable plate 14, a distance is left between the magnetic block 24 and the first magnetic conductive member 21, and the magnetic block 24 contacts the first magnetic conductive member 21 after moving.

[0042] Specifically, the first magnetic conductive member 21 and the second magnetic conductive member 22 are both made of materials that can be magnetized by the magnetic block 24. After being magnetized, the magnetic conductive member has magnetic properties and is attracted to the magnetic conductive plate 23. Figure 3 and Figure 5 In the figure, the cylindrical section on the left side of the first magnetic conductive member 21 extends to the bottom of the rotating shaft 13, the bottom end of the second magnetic conductive member 22 extends to the bottom of the slide plate 12, the right side of the bottom end of the second magnetic conductive member 22 is connected to the bottom end of the cylindrical section in the first magnetic conductive member 21, and the magnetic conductive plate 23 is located on the inner bottom wall of the main seat 11; it should be noted that other structures that can also meet the requirement that the first magnetic conductive member 21, the second magnetic conductive member 22 and the magnetic conductive plate 23 are always in contact during the rotation of the rotating shaft 13 are suitable for the manufacture of the first magnetic conductive member 21, the second magnetic conductive member 22 and the magnetic conductive plate 23.

[0043] When measuring the wall angle, it is necessary to rotate the movable plate 14 so that the movable plate 14 is attached to the wall B. When the movable plate 14 rotates, it will drive the slide plate 12 to slide in the main seat 11. In order to improve the smoothness of the operation, initially, the movable plate 14 and the slide plate 12 are easy to move. However, this setting also creates a problem, that is, after the movable plate 14 is attached to the wall B in parallel, the easy-to-move feature of the movable plate 14 will cause the relative position of the two to be unstable, and the angle between the two may change; for scenes such as a small wall angle, it may be inconvenient to read data when the measuring device is attached to the wall. At this time, the measuring device needs to be taken out from between the walls. During the removal process, due to the unstable position of the movable plate 14 and the slide plate 12, the angle between the two may change, thereby affecting the measurement result. In order to improve this problem, a positioning mechanism 2 is provided.

[0044] Initially, the magnetic block 24 is not in contact with the first magnetic conductive member 21, the first magnetic conductive member 21 and the second magnetic conductive member 22 are not magnetic, and there is no magnetic attraction between the magnetic conductive plate 23 and the two magnetic conductive members, which will not hinder the normal movement of the slide plate 12 and the movable plate 14;

[0045] After the main seat 11 is attached to the wall A and the movable plate 14 is attached to the wall B, the magnetic block 24 is moved so that the magnetic block 24 contacts the first magnetic member 21, and the first magnetic member 21 and the second magnetic member 22 are magnetized. After the first magnetic member 21 and the second magnetic member 22 are magnetized, they are attracted to the magnetic plate 23, so that the slide plate 12 and the rotating shaft 13 are fixed inside the main seat 11, and then the movable plate 14 and the slide plate 12 are fixed together to form a stable overall structure. In this way, even if the measuring device is taken out from between the two walls for reading, the angle between the movable plate 14 and the slide plate 12 remains fixed, so that the angle data between the two walls can be accurately measured and read, thereby improving the above-mentioned problem.

[0046] like Figure 2-7 As shown, it also includes several groups of driving mechanisms 3 arranged on the movable plate 14, and the driving mechanism 3 includes: a detection plate 31 slidably arranged on the abutment plate 17; and a first spring 32 for pushing the detection plate 31 to extend to the outside of the abutment plate 17.

[0047] Specifically, the number of the driving mechanisms 3 is preferably but not limited to two groups, and the example of setting two detection plates 31 is used for explanation. Figure 2 In the embodiment, the two detection plates 31 are distributed along the X-axis, and the first spring 32 is used to push the detection plate 31 to move along the negative direction of the Z-axis and extend to the outside of the abutment plate 17 .

[0048] like Figure 2-7 As shown, the detection plate 31 is T-shaped, and the driving mechanism 3 also includes a recessed groove 33 provided on the abutment plate 17 corresponding to the detection plate 31. The two ends of the first spring 32 are respectively connected to the bottom of the recessed groove 33 and the detection plate 31. The detection plate 31 moves toward the inside of the abutment plate 17 and then sinks into the recessed groove 33.

[0049] Specifically, when the movable plate 14 is attached to the wall B, when the two detection plates 31 are in contact with the wall B and are squeezed into the sink 33, the two detection plates 31 are attached to the wall B. At this time, it means that the movable plate 14 is parallel to the wall B.

[0050] like Figure 2-9As shown, the driving mechanism 3 also includes: an inner sliding rod 34 fixedly connected to the magnetic block 24; a limit plate 35 fixedly connected to the inner sliding rod 34; a baffle 36 slidably arranged inside the movable plate 14, the baffle 36 is used to block the limit plate 35; and a return spring 37 arranged on the movable plate 14 for pushing the baffle 36 close to the limit plate 35.

[0051] Specifically, after pressing the two inner slide bars 34 and driving the magnet block 24 to move, the position of the magnet block 24 can be fixed, and the two inner slide bars 34 are pressed again, and the magnet block 24 can be moved back and reset; initially, the two baffles 36 block the two limit plates 35, thereby preventing the inner slide bars 34 and the magnet block 24 from moving. At this time, the magnet block 24 does not contact the first magnetic conductive member 21, and the two ends of the reset spring 37 are respectively connected to the limit plates 35 and the movable plate 14. It should be noted that the structure and installation position of the reset spring 37 are not limited to Fig. 9 Examples in .

[0052] like Figure 2-8 As shown, the inner slide rod 34 is movably inserted into the interior of the detection plate 31, and the positioning mechanism 2 also includes: a bevel plate 25 fixedly connected to the detection plate 31, the bottom of the bevel plate 25 is provided with a bevel, and the baffle plate 36 is provided with a slot corresponding to the bevel plate 25. After the detection plate 31 moves, the bevel plate 25 drives the baffle plate 36 away from the limit plate 35; a second spring 27 is arranged between the detection plate 31 and the limit plate 35.

[0053] Specifically, initially Figure 7 As shown, the bevel plate 25 is separated from the baffle plate 36, and the baffle plate 36 blocks the limit plate 35, thereby fixing the inner slide rod 34 and the magnet 24, and the magnet 24 is not in contact with the first magnetic conductive member 21; when the movable plate 14 is placed on the wall B, the detection plate 31 is squeezed into the sink groove 33 after contacting the wall. In this process, the first spring 32 and the second spring 27 are both compressed. After the detection plate 31 moves, the bevel plate 25 contacts the slot in the baffle plate 36 and squeezes the baffle plate 36 to move, so that the baffle plate 36 is separated from the limit plate 35. Only when the two detection plates 31 are in contact with the wall and are completely squeezed into the sink groove 33, the bevel plate 25 contacts the slot, driving the two baffle plates 36 to separate from the limit plate 35, and the magnet 24 will move under the push of the second spring 27. By setting up two detection plates 31, when both ends of the abutment plate 17 are completely in contact with the wall and the two detection plates 31 are squeezed into the sink 33, the magnetic block 24 is triggered to move to contact the first magnetic conductive member 21, so as to position the slide plate 12 and the movable plate 14, avoid accidental touching, and facilitate use.

[0054] After the magnetic block 24 contacts the first magnetic conductive member 21, the suction force between the two is not less than the force of the first spring 32 and the second spring 27, so that after the detection plate 31 is squeezed into the sink 33 by the wall, the detection plate 31 maintains a stable position under the suction force between the magnetic block 24 and the first magnetic conductive member 21.

[0055] like Figure 7 As shown, a space for operating the detection plate 31 is reserved in the sink 33 , and a limiting boss 26 is provided at the end of the inner slide rod 34 .

[0056] Specifically, when the detection plate 31 is reset, the staff can insert their fingers into the groove 33 and push the detection plate 31 outward. When the detection plate 31 moves toward the outside of the abutment plate 17, the inner slide rod 34 and the magnetic block 24 are driven to move outward through the limiting boss 26, so that the magnetic block 24 is separated from the first magnetic conductive component 21.

[0057] Embodiment 2: Figure 2-9 As shown, compared with Example 1, another implementation of the present invention is: the positioning mechanism 2 also includes: a blocking plate 28 slidably arranged inside the movable plate 14, the blocking plate 28 is blocked between the magnetic block 24 and the first magnetic conductive member 21; a transmission gear set 29 rotatably arranged inside the movable plate 14, and the transmission is carried out between the baffle plate 36 and the blocking plate 28 through the transmission gear set 29.

[0058] Specifically, the blocking plate 28 is made of non-magnetic material, and two blocking plates 28 are preferably provided. The two blocking plates 28 separate the space between the magnetic block 24 and the first magnetic conductive part 21, thereby blocking the magnetic field and reducing the magnetization of the first magnetic conductive part 21 under non-contact conditions. The transmission gear set 29 plays a role in amplifying the stroke. The transmission gear set 29 is preferably but not limited to two gear parts with different outer diameters. Rack sections are respectively provided on the baffle plate 36 and the blocking plate 28. The baffle plate 36 is meshedly connected to one of the gear parts, and the blocking plate 28 is meshedly connected to the other gear part. After the baffle plate 36 moves, the blocking plate 28 is driven to move by the transmission gear set 29, and the amplifying effect of the transmission gear set 29 is used to amplify the moving stroke of the blocking plate 28, so that the blocking plate 28 is completely separated from the magnetic block 24, so that the magnetic block 24 can pass through between the two blocking plates 28 and contact the first magnetic conductive part 21.

[0059] It should be noted that Figure 7For example, after the blocking plates 28 move to both sides and the magnetic block 24 moves to contact and attract the first magnetic conductive member 21, the two blocking plates 28 respectively rest on the left and right side walls of the magnetic block 24. When the magnetic block 24 moves back and is reset, the two blocking plates 28 also move back to between the magnetic block 24 and the first magnetic conductive member 21, and the baffle 36 also blocks it again. Of course, a slope can also be provided on the limit plate 35 to push the baffle 36 away from the inner slide rod 34, so as to further ensure that the limit plate 35 and the inner slide rod 34 can move back and be reset.

[0060] Working principle: When measuring the angle between the connected wall A and wall B, the main seat 11 is attached to the wall A, so that the slide plate 12 in the main seat 11 is parallel to the wall A, and the movable plate 14 is rotated and slid until the movable plate 14 is attached to the wall B, so that the movable plate 14 is parallel to the wall B. In this way, the slide plate 12 and the movable plate 14 are parallel to the two walls respectively, and the angle between the slide plate 12 and the movable plate 14 is the angle between the two walls. The rotation angle of the rotating shaft 13 is detected by the angle sensor 15. If conditions permit, the display screen 16 can be observed at this time, and then the angle data between the two walls can be directly obtained, which saves the trouble of removing the measuring device and then using a protractor and other devices for measurement. The operation is fast and the work efficiency is high;

[0061] When the movable plate 14 contacts the wall B, the detection plate 31 contacts the wall B and is squeezed into the sink 33 by the wall. When both detection plates 31 are squeezed into the sink 33, it indicates that the movable plate 14 is parallel to the wall B.

[0062] When the detection plate 31 is squeezed into the sink 33, the first spring 32 and the second spring 27 are both compressed. After the detection plate 31 moves inward, the bevel plate 25 contacts the slot in the baffle plate 36 and squeezes the baffle plate 36 to move, so that the baffle plate 36 is separated from the limit plate 35.

[0063] After the baffle plate 36 moves, the blocking plate 28 is driven to move by the transmission gear set 29, and the moving stroke of the blocking plate 28 is amplified by the amplification effect of the transmission gear set 29, so that the blocking plate 28 is completely separated from the magnetic block 24;

[0064] Without the restraint of the baffle 36, the magnetic block 24 passes through the two blocking plates 28 under the push of the second spring 27 and contacts the first magnetic conductive member 21, magnetizing the first magnetic conductive member 21 and the second magnetic conductive member 22. After being magnetized, the first magnetic conductive member 21 and the second magnetic conductive member 22 are attracted to the magnetic conductive plate 23, thereby fixing the slide plate 12 and the rotating shaft 13 inside the main seat 11, and then fixing the movable plate 14 and the slide plate 12 together to form a stable overall structure. At this time, the detection plate 31 also maintains a stable position under the suction force between the magnetic block 24 and the first magnetic conductive member 21, and the two blocking plates 28 are respectively against the left and right side walls of the magnetic block 24, and the movable plate 14 The positions of the slide plate 12 and the movable plate 14 can remain relatively unchanged, and the angle between the two is consistent with the angle between the two walls. Then the measuring device is taken out from between the two walls to read the angle value, which realizes the function of taking out the measuring device for reading when the angle between the walls is too small and it is not suitable to directly observe the display screen 16. In the process of taking out, the slide plate 12 and the movable plate 14 can still keep their positions fixed, ensuring that the measurement results do not change, and improving the problem of the measurement results being affected by the movement of the slide plate 12 and the movable plate 14; therefore, when the device is in use, regardless of whether it is necessary to take out the reading, the positioning work can ensure the stability of the measurement.

[0065] It should be noted that only when the abutment plate 17 on the movable plate 14 is completely in contact with the wall, that is, the movable plate 14 is in contact with and parallel to the wall, the two detection plates 31 are in contact with the wall and are completely squeezed into the sink 33, the bevel plate 25 will contact the slot, driving the two baffles 36 to separate from the limit plate 35, and the magnetic block 24 will move under the push of the second spring 27, and then trigger the magnetic block 24 to move to contact the first magnetic conductive part 21, so as to position the slide plate 12 and the movable plate 14, avoid the occurrence of accidental touching, and make the measurement more accurate and the use more convenient.

[0066] When the wall angle measurement is completed and the detection plate 31 needs to be reset, the staff member inserts his finger into the groove 33 and pushes the detection plate 31 outward. When the detection plate 31 moves toward the outside of the abutment plate 17, the inner slide rod 34 and the magnetic block 24 are driven to move outward through the limit boss 26, so that the magnetic block 24 is separated from the first magnetic conductive member 21, and the first magnetic conductive member 21 and the second magnetic conductive member 22 lose their magnetism and are no longer attracted to the magnetic conductive plate 23. Then the movable plate 14 can be easily rotated and retracted into the slide plate 12. When the movable plate 14 is rotated and retracted into the slide plate 12, after the movable plate 14 is fitted with the origin limit block 121, the angle between the movable plate 14 and the slide plate 12 is 0. At this time, the movable plate 14 is in the origin position, and the entire device has completed the reset and zeroing for the next use. The measuring device has a compact structure, fast operation, and is easy to carry and use.
