Description

Technical Field

[0001] The invention relates to the technical field of wall verticality measurement, in particular to a building wall verticality measurement device. Background Art

[0002] After the construction of the building wall is completed, it is necessary to check the verticality of the wall. The general measurement method is for the staff to measure with a 2-meter ruler. When measuring, the 2-meter ruler is placed on the surface of the wall and in close contact with the wall, and the verticality of the wall is judged by the data displayed on the dial.

[0003] Some existing wall verticality detection uses electronic equipment such as laser levels. Their use requires precise positioning first, and the positions of the initial point and the final point are used to determine whether the wall is vertical. However, if the center of the wall is concave or convex, it cannot be effectively detected. Its scope of use is limited, and installation requires a certain amount of time and adjustment. The 2-meter ruler is a frequently used verticality detection tool for house inspection or building verticality detection. The 2-meter ruler can effectively measure the verticality of various parts of the wall by directly attaching it to the wall. The principle of use of the 2-meter ruler is that the center line of the ruler is parallel to the edge line of the ruler, and the plumb line of the center line uses the principle of downward center of gravity. When the center line coincides with the plumb line, the ruler is vertical, and when the edge line coincides, the ruler is vertical. If the line fits tightly with the wall, it means that the verticality of the wall is good. Since the above-mentioned ruler uses the above-mentioned principle, even if the ruler is slightly tilted laterally when in use, since the wall is flat, the measured data is also representative to a certain extent, and the requirement for the inclination of the ruler is not high. However, this method can only be used for flat walls. In actual operation, some personnel sometimes set the wall to be an arc surface to meet different design requirements. The arc surface wall has high requirements for the verticality of the measuring area. During measurement, once the ruler is tilted in the lateral direction, the measurement data of the ruler is not accurate. The verticality of the ruler is corrected by human eye observation, which has errors. Therefore, a building wall verticality measuring device is proposed to address the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a device for measuring the verticality of a building wall to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] As an optional solution of the verticality measuring device for a building wall of the present invention, a verticality measuring device for a building wall includes a first ruler and a second ruler.

[0007] One end of the first ruler is rotatably connected to the second ruler via a connecting piece;

[0008] The outer sides of the first ruler and the second ruler are both equipped with anti-slip grips;

[0009] The outer side of the first ruler is respectively installed with a pointer adjustment screw, a movable pin and an instrument dial which are distributed in sequence up and down, and the outer side of the second ruler is installed with a level tube;

[0010] A placement slot is provided inside the first ruler and the second ruler, a third magnet is installed inside the placement slot, a rotating shaft fixedly connected to the first ruler and the second ruler is provided inside the placement slot, a rotating cylinder is rotatably connected to the outer side of the rotating shaft, a rotating plate is fixedly connected to the outer side of the rotating cylinder, the other end of the rotating plate on one side is fixedly connected to the display module, and the other end of the rotating plate on the other side is fixedly connected to the vertical correction module;

[0011] The vertical correction module includes a mounting frame, a connecting rope and a laser light, one side of the mounting frame is fixedly connected to the rotating plate, the center of the mounting frame is fixedly connected to the connecting rope, and the other end of the connecting rope is fixedly connected to the laser light, a first magnet is installed on the outside of the mounting frame, a quick anti-sway assembly is installed on one side of the mounting frame, a protection module is installed on the other side of the mounting frame, and a shielding plate is slidably connected to the bottom layer of the mounting frame;

[0012] The protection module comprises a first protection plate and a second protection plate, the outer side of the first protection plate is fixedly connected to the installation frame, the second protection plate is arranged below the first protection plate, a sliding plate is slidably connected to the interior of the first protection plate, and a connecting plate is fixedly connected to the bottom of the sliding plate, one end of the connecting plate is fixedly connected to a handle, and the outer side of the connecting plate is fixedly connected to the second protection plate;

[0013] The quick anti-sway assembly includes a fixing frame, a motor and a threaded shaft. The outer side of the fixing frame is fixedly connected to the installation frame, the inner side of the fixing frame is fixedly connected to the motor, the end of the main shaft of the motor is fixedly connected to the threaded shaft, the outer side of the threaded shaft is spirally connected to a threaded sleeve, and the other end of the threaded sleeve is fixedly connected to the anti-sway frame;

[0014] The display module comprises a display panel, a correction plate and a second magnet. One side of the display panel is fixedly connected to the rotating plate, and the correction plate and the second magnet are mounted on the upper surface of the display panel.

[0015] The principle of using a 2-meter ruler is to use the parallelism of the center line of the ruler and the edge line of the ruler, and the plumb bob of the center line uses the principle of the center of gravity pointing downward. When the center line coincides with the plumb line, the ruler is vertical. When the edge line fits tightly against the wall, it means that the verticality of the wall is good. Since the ruler uses the above principle, even if the ruler is slightly tilted laterally during use, since the wall surface is flat, the measured data is also representative to a certain extent, and the requirements for the inclination of the ruler are not high. However, this method can only be used for flat walls. In actual operation, some personnel sometimes set the wall surface to be an arc surface in order to meet different design requirements. The arc surface wall has high requirements for the verticality of the measurement area. During measurement, once the ruler is tilted in the lateral direction, the measurement data of the ruler is not accurate. The verticality of the ruler is corrected by human eye observation, which has errors. When the present invention is used, when measuring the verticality of the arc surface wall, the first ruler and the second ruler are first unfolded, and the instrument is calibrated. Then rotate the vertical correction module and the display module. At this time, the vertical correction module and the display module drive the rotating plate to rotate, and the rotating plate drives the rotating cylinder to rotate outside the rotating shaft. At this time, the first magnet and the second magnet on the outside of the vertical correction module and the display module are separated from the third magnet. At this time, the vertical correction module and the display module are extended and arranged horizontally, and one side of the first ruler and the second ruler are close to one side of the curved wall. By taking out the baffle plate and starting the quick anti-sway assembly, it can contact with the connecting rope at this time, and the connecting rope can be quickly stationary, and the laser light is stationary to ensure that the laser of the laser light is irradiated on the surface of the display board. When the laser point is located on the surface of the correction plate, it means that the first ruler and the second ruler are vertical. At this time, the measured data is accurate. When the laser points are located on both sides of the correction plate, it means that the first ruler and the second ruler are tilted. At this time, the positions of the first ruler and the second ruler need to be adjusted. This setting can ensure that the ruler can achieve accurate measurement of the curved wall when in use.

[0016] As an optional solution of the building wall verticality measuring device described in the present invention, a spring is arranged on the outer side of the connecting plate, one end of the spring is fixedly connected to the sliding plate, and the other end of the spring is fixedly connected to the first protective plate.

[0017] As an optional solution of the building wall verticality measuring device described in the present invention, a guide column is fixedly connected to the upper part of the second protective plate, and the outer side of the guide column is slidably connected to the first protective plate.

[0018] The sliding plate can be pulled upward by the spring to ensure that the first protective plate fits the second protective plate to protect the laser lamp. When the second protective plate moves, the guide column provided at this time can ensure that the second protective plate slides up and down stably.

[0019] As an optional solution of the building wall verticality measuring device described in the present invention, wherein: a guide plate is fixedly connected to the outer side of the threaded sleeve, and the outer side of the guide plate is slidably connected to the fixed frame.

[0020] As an optional solution of the building wall verticality measuring device described in the present invention, wherein: a side of the threaded sleeve away from the anti-sway frame is fixedly connected to a limiting plate.

[0021] When the threaded sleeve moves, the guide plate is used to ensure the stable movement of the threaded sleeve, and the limit plate is used to prevent the threaded sleeve from being separated from the fixed frame.

[0022] As an optional scheme of the building wall verticality measuring device described in the present invention, a sliding groove and a storage groove are provided on one side of the first ruler and the second ruler, the first ruler and the second ruler are respectively slidably connected to a sliding plate through the sliding groove, and a sliding block is fixedly connected to one side of the sliding plate, the outer side of the sliding block is fixedly connected to a fixed plate, the other end of the fixed plate is fixedly connected to a rejecting plate, one side of the sliding block is also fixedly connected to a fifth magnet, and a fourth magnet is installed at one end inside the sliding groove.

[0023] As an optional solution of the building wall verticality measuring device described in the present invention, the sliding groove is arranged in a J shape, and the receiving groove is arranged in an arc shape.

[0024] As an optional solution of the building wall verticality measuring device described in the present invention, one end of the rejection plate is set as a pointed end, and one side of the two groups of rejection plates is set in close contact with one side of the first ruler and the second ruler.

[0025] After the first ruler and the second ruler have been used for a period of time, the end surfaces that are close to the wall may be attached with impurities such as cement residues. The presence of solid impurities will cause one end of the first ruler and the second ruler to be unable to fit closely to the wall, thereby affecting the measurement accuracy. The fixed plate is driven to move by the sliding slider, and the fixed plate drives the rejection plate to detach from the storage groove, and the tip surface of the rejection plate is in close contact with the end surfaces of the first ruler and the second ruler that are in contact with the wall. At this time, the impurities on the measuring surface can be rejected to ensure the accuracy of the ruler measurement.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] When the present invention is used, when measuring the verticality of a curved wall, the first ruler and the second ruler are unfolded, and then the vertical correction module and the display module are rotated and extended, and one side of the first ruler and the second ruler is pressed against one side of the curved wall. By taking out the shielding plate and starting the quick anti-sway component, it can contact with the connecting rope, and the connecting rope can be quickly stationary to ensure that the laser of the laser lamp irradiates the surface of the display board. When the laser point is located on the surface of the correction plate, it means that the first ruler and the second ruler are vertical, and the measured data is accurate at this time. When the laser points are located on both sides of the correction plate, it means that the first ruler and the second ruler are tilted, and the positions of the first ruler and the second ruler need to be adjusted at this time. This setting can ensure that the rulers can achieve accurate measurement of the curved wall when in use;

[0028] When the laser light is lowered, the laser light will drive the connecting rope to swing back and forth. At this time, the motor is started to drive the threaded shaft to rotate, and then the threaded sleeve is moved, so that the inner side of the anti-sway frame contacts the connecting rope, so as to achieve the purpose of quickly stopping the laser light from shaking, ensuring that the laser light can be put into use quickly.

[0029] After use, the second protective plate is moved by pulling the handle, and then the laser lamp is placed inside the first protective plate and the second protective plate. The second protective plate can be moved up by the spring. At this time, the first protective plate and the second protective plate protect the laser lamp to prevent it from shaking and colliding at will and being damaged.

[0030] After the first ruler and the second ruler have been used for a period of time, the end surface that is close to the wall may be attached with impurities such as cement residues. The presence of solid impurities will cause one end of the first ruler and the second ruler to be unable to fit closely to the wall, thereby affecting the measurement accuracy. The fixed plate is driven to move by the sliding slider, and the fixed plate drives the rejection plate to detach from the storage groove, and the tip surface of the rejection plate is in close contact with the end surface of the first ruler 1 and the second ruler that is in contact with the wall. At this time, the impurities on the measuring surface can be removed to ensure the accuracy of the ruler measurement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] Example 1: Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the present invention provides a technical solution:

[0041] A device for measuring the verticality of a building wall comprises a first ruler 1 and a second ruler 2.

[0042] One end of the first ruler 1 is rotatably connected to the second ruler 2 via a connecting piece;

[0043] The outer sides of the first ruler 1 and the second ruler 2 are both provided with anti-skid grips 3;

[0044] The outer side of the first ruler 1 is respectively installed with a pointer adjustment screw 6, a movable pin 5 and an instrument dial 4 which are distributed in sequence up and down, and the outer side of the second ruler 2 is installed with a level tube 7;

[0045] The first ruler 1 and the second ruler 2 are provided with placement grooves inside, and the third magnets 13 are installed inside the placement grooves. The rotation shafts 12 fixedly connected to the first ruler 1 and the second ruler 2 are provided inside the placement grooves. The outer sides of the rotation shafts 12 are rotatably connected to the rotation cylinders 11, and the outer sides of the rotation cylinders 11 are fixedly connected to the rotation plates 10, wherein the other end of the rotation plate 10 on one side is fixedly connected to the display module 9, and the other end of the rotation plate 10 on the other side is fixedly connected to the vertical correction module 8;

[0046] The vertical correction module 8 comprises a mounting frame 801, a connecting rope 802 and a laser light 803. One side of the mounting frame 801 is fixedly connected to the rotating plate 10. The center of the mounting frame 801 is fixedly connected with the connecting rope 802, and the other end of the connecting rope 802 is fixedly connected with the laser light 803. A first magnet 804 is installed on the outside of the mounting frame 801. A quick anti-sway component 807 is installed on one side of the inside of the mounting frame 801. A protective module 805 is installed on the other side of the inside of the mounting frame 801. A shielding plate 806 is slidably connected to the bottom layer of the mounting frame 801.

[0047] The protection module 805 includes a first protection plate 8051 and a second protection plate 8052. The outer side of the first protection plate 8051 is fixedly connected to the installation frame 801. The second protection plate 8052 is arranged below the first protection plate 8051. The interior of the first protection plate 8051 is slidably connected to a sliding plate 8053, and the bottom of the sliding plate 8053 is fixedly connected to a connecting plate 8054. A handle 8055 is fixedly connected to one end of the connecting plate 8054. The outer side of the connecting plate 8054 is fixedly connected to the second protection plate 8052.

[0048] The above-mentioned quick anti-sway component 807 includes a fixed frame 8071, a motor 8072 and a threaded shaft 8073. The outer side of the above-mentioned fixed frame 8071 is fixedly connected to the installation frame 801, the inside of the above-mentioned fixed frame 8071 is fixedly connected to the motor 8072, the end of the main shaft of the above-mentioned motor 8072 is fixedly connected to the threaded shaft 8073, the outer side of the above-mentioned threaded shaft 8073 is spirally connected to a threaded sleeve 8074, and the other end of the threaded sleeve 8074 is fixedly connected to the anti-sway frame 8075;

[0049] The display module 9 includes a display panel 901 , a correction plate 902 and a second magnet 903 . One side of the display panel 901 is fixedly connected to the rotating plate 10 . The correction plate 902 and the second magnet 903 are mounted on the upper surface of the display panel 901 .

[0050] The principle of using a 2-meter ruler is to use the parallelism of the center line of the ruler and the edge line of the ruler, and the plumb bob of the center line uses the principle of the center of gravity pointing downward. When the center line coincides with the plumb line, the ruler is vertical. When the edge line fits tightly against the wall, it means that the verticality of the wall is good. Since the ruler uses the above principle, even if the ruler is slightly tilted laterally during use, since the wall surface is flat, the measured data is also representative to a certain extent, and the requirements for the inclination of the ruler are not high. However, this method can only be used for flat walls. In actual operation, some personnel sometimes set the wall surface to be an arc surface in order to meet different design requirements. The arc surface wall has high requirements for the verticality of the measurement area. During measurement, once the ruler tilts in the lateral direction, the measurement data of the ruler is not accurate. The verticality of the ruler is corrected by human eye observation, which has errors. When the present invention is used, when measuring the verticality of the arc surface wall, the first ruler 1 and the second ruler 2 are first unfolded, the instrument is calibrated, and then the vertical correction module 8 and the display module 9 are rotated. At this time, the vertical correction module 8 The display module 9 drives the rotating plate 10 to rotate, and the rotating plate 10 drives the rotating cylinder 11 to rotate outside the rotating shaft 12. At this time, the first magnet 804 and the second magnet 903 on the outside of the vertical correction module 8 and the display module 9 are separated from the third magnet 13. At this time, the vertical correction module 8 and the display module 9 are extended and arranged horizontally, and one side of the first ruler 1 and the second ruler 2 are close to one side of the curved wall. By taking out the shielding plate 806 and starting the quick anti-sway component 807, it can contact with its connecting rope 802 at this time, and the connecting rope 802 can be quickly stationary, and the laser light 803 is stationary to ensure that the laser of the laser light 803 irradiates the surface of the display board 901. When the laser point is located on the surface of the correction plate 902, it means that the first ruler 1 and the second ruler 2 are vertical. At this time, the measured data is accurate. When its laser point is located on both sides of the correction plate 902, it means that the first ruler 1 and the second ruler 2 are tilted. At this time, it is necessary to adjust the position of the first ruler 1 and the second ruler 2. This setting can ensure that the ruler can achieve accurate measurement of the curved wall when in use;

[0051] In this embodiment, the shielding plate 806 is pulled out, and when the laser lamp 803 is lowered, the laser lamp 803 will drive the connecting rope 802 to swing back and forth. At this time, the correction work cannot be performed, and the threaded shaft 8073 is driven to rotate by starting the motor 8072, thereby moving the threaded sleeve 8074 and extending the anti-sway frame 8075, so that the inner side of the anti-sway frame 8075 contacts the connecting rope 802, so as to achieve the purpose of quickly stopping the laser lamp 803 from shaking, and ensure that the laser lamp 803 can be put into use quickly. At the same time, the inner side of the anti-sway frame 8075 is set in an arc shape, and at this time it can contact the connecting rope 802 and gather to the center of the anti-sway frame 8075, so as to achieve rapid connection. The rope 802 stops shaking, and the laser light 803 is left still and then irradiates the display board 901 above the display module 9 below. When the irradiation point of the laser light 803 is located on the surface of the correction plate 902, it means that the first ruler 1 and the second ruler 2 are in a vertical state. When the irradiation point of the laser light 803 is located on both sides of the correction plate 902, it means that the ruler is tilted laterally. At this time, it is necessary to adjust the angle of the ruler to ensure the measurement accuracy. The correction plate 902 is in a rectangular frame setting. When the laser point of the laser light 803 is located on the front and back sides of the correction plate 902, the rulers are in a vertical state, but the wall may be tilted, and the rulers can measure its tilt data.

[0052] After use, the second protective plate 8052 is moved by pulling the handle 8055, and the handle 8055 simultaneously drives the sliding plate 8053 to compress the spring 8056, and then the laser lamp 803 is placed inside the first protective plate 8051 and the second protective plate 8052, and the second protective plate 8052 is moved upward under the action of the spring 8056. At this time, the first protective plate 8051 and the second protective plate 8052 protect the laser lamp 803 to prevent it from shaking and colliding at will and being damaged;

[0053] At the same time, when measuring the verticality of a flat wall, the vertical correction module 8 and the display module 9 are rotated. At this time, the first magnet 804 and the second magnet 903 inside the vertical correction module 8 and the display module 9 cooperate with the third magnet 13 inside the placement groove inside the ruler to achieve the purpose of fixing the vertical correction module 8 and the display module 9, ensuring that the ruler can perform normal verticality measurement of the flat wall;

[0054] In actual use, protective handles 3 are installed on the outer sides of the first ruler 1 and the second ruler 2 to prevent slipping and facilitate the staff to hold them. A connecting piece is provided between the first ruler 1 and the second ruler 2 for connection, and can be fixed by an external limit assembly (not shown in the figure). The level tube 7, pointer adjustment screw 6, movable pin 5 and instrument dial 4 are all inherent devices for ruler measurement and belong to existing products. Therefore, their internal structure and principle will not be described in detail here.

[0055] Example 2: This example is an improvement on Example 1. Figure 3 Specifically, a spring 8056 is provided on the outer side of the connecting plate 8054 , one end of the spring 8056 is fixedly connected to the sliding plate 8053 , and the other end of the spring 8056 is fixedly connected to the first protective plate 8051 .

[0056] A guide column 8057 is fixedly connected to the upper part of the second protective plate 8052 , and the outer side of the guide column 8057 is slidably connected to the first protective plate 8051 .

[0057] The sliding plate 8053 can be pulled upward by the spring 8056 to ensure that the first protective plate 8051 and the second protective plate 8052 fit together to protect the laser lamp 803. When the second protective plate 8052 moves, the guide column 8057 can ensure that the second protective plate 8052 slides up and down stably.

[0058] In this embodiment, a slot matching the laser lamp 803 is formed on the opposite end surfaces of the first protective plate 8051 and the second protective plate 8052 , and the laser lamp 803 can be placed therein to protect the laser lamp 803 .

[0059] Example 3: This example is an improvement on Example 2. Figure 4 Specifically, the outer side of the threaded sleeve 8074 is fixedly connected with a guide plate 8076, and the outer side of the guide plate 8076 is slidably connected with the fixed frame 8071.

[0060] The side of the threaded sleeve 8074 away from the anti-sway frame 8075 is fixedly connected to the limiting plate 8077.

[0061] When the threaded sleeve 8074 moves, the guide plate 8076 is used to ensure the stable movement of the threaded sleeve 8074, and the limit plate 8077 is used to prevent the threaded sleeve 8074 from being separated from the fixed frame 8071;

[0062] In this embodiment, the guide plate 8076 is arranged in a strip shape and is slidably connected to the fixed frame 8071, so it can serve the purpose of guidance. The diameter of the limiting plate 8077 is larger than the discharge port on one side of the fixed frame 8071 that matches the threaded sleeve 8074. The limiting plate 8077 serves the purpose of limiting and preventing the threaded sleeve 8074 from separating from the fixed frame 8071.

[0063] Example 4: This example is an improvement on Example 3. Figure 2 , Figure 7 and Figure 8Specifically, a slide groove 15 and a storage groove 19 are provided on one side of the first ruler 1 and the second ruler 2, and the first ruler 1 and the second ruler 2 are respectively slidably connected to a sliding plate 16 through the slide groove 15, and a slider 14 is fixedly connected to one side of the sliding plate 16, and a fixed plate 17 is fixedly connected to the outer side of the slider 14, and a rejection plate 18 is fixedly connected to the other end of the fixed plate 17, and a fifth magnet 21 is also fixedly connected to one side of the slider 14, and a fourth magnet 20 is installed at one end inside the slide groove 15.

[0064] The slide groove 15 is arranged in a J shape, and the receiving groove 19 is arranged in an arc shape.

[0065] One end of the above-mentioned rejection plate 18 is set to be pointed, and one side of the two groups of the above-mentioned rejection plates 18 is set to be in close contact with one side of the first ruler 1 and the second ruler 2.

[0066] After the first ruler 1 and the second ruler 2 have been used for a period of time, the end surfaces thereof that are in close contact with the wall may be attached with impurities such as cement residues. The presence of solid impurities will cause one end of the first ruler 1 and the second ruler 2 to be unable to fit closely with the wall, thereby affecting the measurement accuracy. The fixed plate 17 is driven to move by the sliding slider 14, and the fixed plate 17 drives the rejection plate 18 to separate from the storage groove 19, and the tip surface of the rejection plate 18 is in close contact with the end surfaces of the first ruler 1 and the second ruler 2 that are in contact with the wall. At this time, the impurities on the measuring surface can be rejected to ensure the accuracy of the ruler measurement.

[0067] In this embodiment, when cleaning impurities from one end face of the ruler, the slider 14 drives the sliding plate 16 to slide inside the slide groove 15, and the sliding plate 16 is located inside the first ruler 1 or the second ruler 2. At this time, the slider 14 can be prevented from being separated from the first ruler 1 or the second ruler 2. When the fifth magnet 21 on one side of the slider 14 is separated from the fourth magnet 20 inside the slide groove 15, the slider 14 moves along the track of the slide groove 15, and the slide groove 15 is arranged in a J shape. At this time, the slider 14 gradually slides out of the arc portion of the J-shaped groove and enters the vertical groove. At the same time, the slider 14 drives the rejection plate 18 on one side to separate from the storage groove 19 under the action of the fixed plate 17, and gradually separates from the one side of the ruler. The side in contact with the wall is in close contact. Since one side of the rejection plate 18 is set with a pointed tip, the width of the rejection plate 18 is the same as the thickness of the ruler. At this time, impurities on the surface of the ruler can be fully removed to ensure subsequent stable use without manual cleaning. The part of the ruler that cannot be cleaned at the bottom of the storage slot 19 can be cleaned manually. After use, the slider 14 slides to the arc portion of the slide slot 15, and the fifth magnet 21 on one side of the slider 14 is fixed with the fourth magnet 20 inside the slide slot 15, and the rejection plate 18 is located inside the storage slot 19. At this time, the measuring surface on one side of the ruler is guaranteed to be flat and accurate, ensuring the quality of subsequent use.
