Description

Technical Field

[0001] The present invention relates to the technical field of wall verticality detection, and particularly to a portable wall verticality calibrator. Background Art

[0002] Wall verticality detection is a key link in building construction, decoration and quality acceptance, directly affecting the structural safety, service function and appearance quality of buildings. Wall verticality refers to the degree of deviation of the wall surface from the plumb line, usually expressed in millimeters per meter or percentage. During the construction process, if the wall is excessively inclined, it may make it difficult to carry out subsequent processes (such as door and window installation, veneer material fitting), and even lead to safety hazards such as structural instability and cracking. Therefore, accurate and efficient verticality detection tools are of great significance for ensuring project quality and construction efficiency.

[0003] Currently, common wall verticality detection methods mainly rely on traditional tools such as plumb lines, laser levels and electronic inclinometers. The plumb line method is simple to operate, but limited by the accuracy of manual visual inspection, easily interfered by environmental factors (such as wind), and it is difficult to quantify the deviation value; although the laser level can provide a high-precision reference line, it is easily blocked in a complex construction site, and the equipment has a large volume and insufficient portability; although the electronic inclinometer can digitally display the inclination angle, it usually needs to be directly attached to the wall surface and cannot adapt to irregular surfaces or high-altitude working environments. In addition, existing devices mostly focus on single measurement functions and lack real-time feedback and automatic calibration mechanisms, resulting in low detection efficiency. Especially during continuous multi-point measurement, it is necessary to repeatedly adjust the device position, which is time-consuming and laborious. To address the above problems, there is an urgent need for a portable detection device with high integration, convenient operation, strong adaptability and automatic compensation function to meet the needs of the modern construction industry for efficient and accurate detection tools. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a portable wall verticality calibrator, which overcomes the deficiencies of the prior art and effectively solves the problem that existing devices mostly focus on single measurement functions and lack real-time feedback and automatic calibration mechanisms, resulting in low detection efficiency.

The wall verticality positioning plate is arranged on the inner wall of the clamping plate. The bidirectional screw rod is rotatably connected to the bottom of the outer wall of one side of the slide rail, and symmetrically distributed L-shaped folding plates are screwed on the outer wall of the bidirectional screw rod. The wall inclination confirmation assembly is arranged between the wall verticality positioning plate and the L-shaped folding plate.

[0008] Preferably, the horizontal adjustment mechanism includes a positioning member, a first elastic compensator, a horizontal adjustment assembly, and a spirit level. Among them, the positioning member, the first elastic compensator, and the horizontal adjustment assembly are all installed between the base and the horizontal platform, and the spirit level is placed on the top of the horizontal platform.

[0009] Preferably, the positioning member includes a ball sleeve and a sphere. Among them, the ball sleeve is welded to the center of the top outer wall of the base, the sphere is welded to the center of the bottom outer wall of the horizontal platform, and the sphere is slidably matched with the ball sleeve.

[0010] Preferably, the first elastic compensator includes hanging rods respectively fixedly connected to the top outer wall of the base and the inner wall of the horizontal platform, and a first spring hanging between the two hanging rods.

[0011] Preferably, the horizontal adjustment assembly includes an internally threaded sleeve rotatably connected to the top outer wall of the base, a turntable fixedly connected to the outer wall of the internally threaded sleeve, and a screw rod screwed on the inner wall of the internally threaded sleeve, and the horizontal platform abuts against the top outer wall of the screw rod.

[0012] Preferably, the verticality dial includes a clamp seat slidably connected to the outer wall of one end of the boom, a dashboard installed on the top outer wall of the clamp seat, and a clock hand rotatably connected to the inner wall of one end of the clamp seat. Among them, a fastening knob is screwed on the outer wall of the boom near the clamp seat, and one end of the fastening knob abuts against the outer wall of the clamp seat.

[0013] Preferably, the second elastic compensator includes a sliding sleeve, a forward push spring, and a pull-back spring. Among them, the sliding sleeve is welded to the bottom outer wall of the boom, the forward push spring and the pull-back spring are respectively installed on the outer walls of both ends of the sliding sleeve, and one outer wall of the forward push spring and the pull-back spring is welded to the outer wall of the cross column. Among them, the cross column is in a trend of being stressed in the direction towards the wall.

[0014] Preferably, the wall inclination confirmation component includes a horizontal wedge, a vertical wedge, a connecting column, and a second spring.

[0018] 1. In the portable wall perpendicularity calibrator of the present invention, the second elastic compensation member provided in the perpendicularity monitoring mechanism includes a forward push spring and a pull-back spring. The two cooperate to act on the cross column, making it always closely attached to the wall surface. This design can automatically compensate for the pressure fluctuations caused by slight unevenness of the wall surface or the sliding of the device, ensuring a constant contact force during the measurement process and reducing human errors. At the same time, the cooperation of the bidirectional lead screw and the L-shaped folding plate enables the synchronous opening and closing of the symmetrical L-shaped folding plates by rotating the bidirectional lead screw, quickly adapting to different wall thicknesses and further improving the measurement stability.

[0019] 2. In the portable wall perpendicularity calibrator of the present invention, the wall inclination confirmation component uses the meshing mechanism of the inclined surfaces of the horizontal wedge and the vertical wedge. When the wall inclination exceeds the threshold, the connecting column is pushed by the second spring, causing the vertical wedge and the horizontal wedge to be locked, triggering the mechanical lock. This structure can quickly determine the excessive inclination without relying on electronic sensors, significantly improving the identification efficiency of unqualified walls, especially suitable for noisy or low-light environments.

The wall inclination confirmation assembly 97 is provided between the wall verticality positioning plate 94 and the L-shaped folding plate 96.

[0032] In this embodiment, the slide rail 5 is fixedly connected to the top of the support frame 4 by screws, and the slide table 6 can slide along the slide rail 5. The arm frame 7 is fixed to one side of the slide table 6. The verticality dial 8 at one end thereof includes a clamp table base 81, a dial plate 82 and a pointer 83. The pointer 83 reflects the wall inclination angle through mechanical linkage. The cross column 92 slides in the sliding sleeve 911 of the second elastic compensator 91.

[0036] The horizontal adjustment assembly 33 includes an internally threaded sleeve 331 rotatably connected to the outer wall of the top of the base 1, a turntable 332 fixedly connected to the outer wall of the internally threaded sleeve 331, and a screw rod 333 screwed on the inner wall of the internally threaded sleeve 331, and the horizontal platform 2 abuts against the outer wall of the top of the screw rod 333.

[0037] Refer to Figure 3 , Figure 5 A handle 10 is welded to the outer wall of one side of the base 1, and a plurality of pads 12 are arranged in an array on the outer wall of the bottom of the base 1.

[0038] In this embodiment, a plurality of pads 12 are provided at the bottom of the base 1 to adapt to uneven ground. The horizontal platform 2 is connected to the ball socket 311 of the base 1 through a sphere 312 to form a universal joint, allowing the horizontal platform 2 to tilt in multiple directions. In the first elastic compensation member 32, the hanging rods 321 are respectively fixed to the top of the base 1 and the inner wall of the horizontal platform 2, and the first spring 322 is hung between the two hanging rods 321 to form an elastic support. The turntable 332 of the horizontal adjustment assembly 33 drives the internally threaded sleeve 331 to rotate, drives the screw rod 333 to lift, pushes a partial area of the horizontal platform 2, and observes the leveling state in combination with the spirit level 34.

[0039] Refer to Figure 6 , the verticality dial 8 includes a clamp base 81 slidably connected to the outer wall of one end of the boom 7, a dial 82 installed on the outer wall of the top of the clamp base 81, and a pointer 83 rotatably connected to the inner wall of one end of the clamp base 81. Among them, a fastening knob is screwed on the outer wall of the end of the boom 7 close to the clamp base 81, and one end of the fastening knob abuts against the outer wall of the clamp base 81.

[0040] Embodiment 3, refer to Figures 7 - 8 , the second elastic compensation member 91 includes a sliding sleeve 911, a forward spring 912 and a pulling-back spring 913. Among them, the sliding sleeve 911 is welded to the outer wall of the bottom of the boom 7, the forward spring 912 and the pulling-back spring 913 are respectively installed on the outer walls of both ends of the sliding sleeve 911, and one ends of the forward spring 912 and the pulling-back spring 913 are welded to the outer wall of the cross column 92. Among them, the cross column 92 is in a trend of being stressed in the direction towards the wall.

[0041] The wall inclination confirmation component 97 includes a horizontal wedge 971, a vertical wedge 972, a connecting column 973, and a second spring 974. Among them, there are two horizontal wedges 971, which are respectively welded to the outer walls on both sides of the wall verticality positioning plate 94. The vertical wedge 972 is closely attached to the inclined surface of the horizontal wedge 971. The connecting column 973 is welded to the bottom outer wall of the vertical wedge 972 of the horizontal wedge 971, and the connecting column 973 is slidably connected to the inner wall of the L-shaped folding plate 96. The second spring 974 is fixedly connected between the connecting column 973 and the L-shaped folding plate 96.

[0042] In this embodiment, when the bidirectional lead screw 95 rotates, the symmetric L-shaped folding plates 96 move synchronously along the thread to adjust the clamping width. When the wall is inclined, the cross column 92 pushes the wall verticality positioning plate 94, driving the horizontal wedge 971 to squeeze the vertical wedge 972. If the inclination exceeds the limit, the connecting column 973 compresses the second spring 974 and triggers the wedge to be stuck, directly locking the abnormal state through mechanical interference, and the operator can immediately identify the unqualified wall.

[0043] Refer to Figure 4 , a horizontal groove 11 is opened at the center of the top outer wall of the horizontal platform 2, and the spirit level 34 is placed on the inner wall of the horizontal groove 11.

[0044] The handle 10 is welded to the side wall of the base 1, which is convenient for single-handed carrying; the spirit level 34 is embedded in the horizontal groove 11 to provide an intuitive horizontal indication.

[0045] Working principle:

[0046] Equipment leveling: Place the base 1 near the wall to be measured and initially stabilize it through the cushion block 12. Rotate the turntable 332 to adjust the height of the screw 333, and observe the spirit level 34 until the horizontal platform 2 is in a horizontal state. The universal connection between the ball socket 311 and the sphere 312 allows for quick fine-tuning.

[0047] Contact positioning: Push the sliding table 6 along the slide rail 5 to the target height, loosen the fastening knob to adjust the position of the dial gauge holder 81, and align the pointer 83 with the detection point. The cross column 92 is closely attached to the wall surface under the action of the forward spring 912, and the clamping plate 93 and the wall verticality positioning plate 94 are synchronously attached.

[0048] Inclination detection: If the wall is inclined, the cross column 92 moves backward under the reaction force, driving the pointer 83 to deflect, and the dial 82 displays the specific deviation value. At the same time, the displacement of the wall verticality positioning plate 94 is transmitted to the vertical wedge 972 through the horizontal wedge 971. When the inclination exceeds the limit, the second spring 974 between the connecting column 973 and the L-shaped folding plate 96 is compressed, and the wedge is engaged and locked to provide a physical alarm.
