Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to a horizontal positioning calibrator for wall construction. Background Technology

[0002] In construction and interior decoration projects, wall leveling and calibration are crucial for ensuring construction quality, directly impacting the accuracy and aesthetics of subsequent processes such as decorative panel installation, pipeline laying, and furniture placement. Therefore, precise, convenient, and stable leveling and calibration tools have become a core requirement for construction workers.

[0003] An existing utility model patent (publication number: CN220136267U) discloses a wall flatness testing level, comprising a measuring ruler body. The measuring ruler body includes a horizontal calibration bubble, a first vertical calibration bubble, and a second vertical calibration bubble. The horizontal calibration bubble is located in the middle of the measuring ruler body, and the first and second vertical calibration bubbles are located at opposite ends of the measuring ruler body. Handle holes are symmetrically arranged on both sides of the horizontal calibration bubble. This utility model wall flatness testing level, by incorporating a horizontal calibration bubble, a first vertical calibration bubble, a second vertical calibration bubble, and a plumb bob measuring component, can perform multi-functional measurements of wall flatness and verticality. The operation method is simple and convenient, and the device integrates multiple functions and is easy to carry.

[0004] The spirit levels cited in the above-mentioned patents rely heavily on calibration bulbs for reading, and the calibration accuracy is easily affected by the observation angle and ambient light. Furthermore, the minimum division value of the calibration bulb is relatively large, making it difficult to accurately identify minute deviations in wall level, resulting in large positioning errors and making it unsuitable for high-precision construction scenarios.

[0005] Based on this, we propose a horizontal positioning calibrator for wall construction. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a horizontal positioning calibrator for wall construction.

[0007] According to the present invention, a horizontal positioning calibrator for wall construction includes a handle, a mounting platform fixedly connected above the handle, an adjustment component installed above the mounting platform, and a calibration component installed on the mounting platform surface of the adjustment component. The mounting platform has an internal sliding groove, and an adjusting screw is threaded to the end of the mounting platform. The adjusting screw passes through the sliding groove and is threaded through a sliding plate. The sliding plate is fixedly connected to the top of the mounting platform and slides axially inside the sliding groove.

[0008] The calibration assembly includes a calibration needle, which is bolted to the surface of the mounting platform. A rotating plate is movably connected to the upper surface of the mounting platform. The surface of the rotating plate has a scale, and the scale that forms a straight line with the calibration needle is the calibration line. A tightening nut is threaded onto the surface of the rotating plate, and a calibration plate is fixedly connected to the outer side of the rotating plate.

[0009] Preferably, the adjusting screw and the sliding plate are threaded transmission structures. When the adjusting screw rotates around its own axis, the sliding plate is driven to slide axially along the slide groove by the thread force. The sliding of the sliding plate can simultaneously drive the mounting platform to adjust its position along the sliding direction of the sliding plate, thereby realizing the adjustment of the lateral positioning distance of the grip.

[0010] Preferably, the operator holds a handle to control the entire device. By rotating the adjusting screw in the adjustment assembly, the screw and the sliding plate are connected via a threaded transmission structure, causing the sliding plate to slide axially along the groove inside the mounting platform. Since the sliding plate is fixedly connected above the mounting platform, its sliding motion synchronously moves the mounting platform, adjusting the position of the handle for easy gripping.

[0011] Preferably, the calibration components are provided in two sets, one set is installed at the front end of the mounting platform and the other set is installed at the middle of the mounting platform.

[0012] Preferably, when the nut is tightened onto the surface of the rotating plate, the rotating plate is not locked in place, and adjustable rotational damping is provided to the rotating plate. This damping allows the rotating plate to maintain its current position when no external force is applied, and to rotate around its movable connection point with the mounting platform when driven by an external force.

[0013] Preferably, when the wall surface to which the calibration plate is attached is not level, the calibration plate is driven by the tilting force of the wall surface to rotate synchronously, thereby causing the calibration needle and the calibration line to be relatively offset, so as to intuitively display the horizontal deviation of the wall surface.

[0014] Preferably, before testing, the damping is adjusted by tightening the nut in the calibration assembly. The nut is threaded onto the surface of the rotating plate, not locking it in place, but providing adjustable rotational damping. This damping allows the rotating plate to maintain its current position when no external force is applied, preventing positional shifts due to slight equipment vibration during testing. Simultaneously, it ensures that the rotating plate can flexibly rotate around its movable connection point with the mounting platform when driven by external force, guaranteeing timely calibration response.

[0015] Preferably, during testing, the calibration plate in the calibration assembly is tightly fitted against the wall to be tested. If the wall is level, the calibration line on the rotating plate is aligned with the calibration needle, which is bolted to the mounting platform, and the absence of horizontal deviation can be confirmed by the scale on the rotating plate surface. If the wall is not level, the inclined wall will exert a lateral force on the calibration plate, causing the calibration plate to rotate synchronously with the rotating plate fixed to it. In this case, the position of the calibration needle remains unchanged, and the calibration line on the rotating plate will be offset relative to the calibration needle. The operator can intuitively and accurately obtain the degree of horizontal deviation of the wall by reading the offset value on the scale, thus completing the horizontal positioning calibration.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Compared to existing levels that rely on calibration bubbles, this patented invention effectively avoids interference from observation angle and ambient light on calibration results through a linked structure of "calibration plate-calibration needle-scale". When the wall surface is slightly tilted, the calibration plate drives the rotating plate to rotate synchronously, causing a noticeable relative offset between the calibration line and the fixed calibration needle. Construction workers can accurately read the deviation value through the scale, and the minimum deviation recognition capability far exceeds the graduation range of the calibration bubble. This design directly solves the problem of large positioning errors in existing tools, and can accurately adapt to processes with stringent requirements for horizontal accuracy, such as the installation of decorative panels and pipeline laying, ensuring the accuracy and aesthetics of subsequent construction.

[0017] 2. The tightening nut designed in this utility model provides adjustable rotational damping, ensuring that the rotating plate can stably maintain its current position when no external force is applied, avoiding calibration position deviation caused by slight equipment shaking, while also allowing flexible rotation under the force of the wall, ensuring timely calibration response. This structure eliminates the need for construction personnel to frequently adjust the equipment posture, reducing errors caused by operational instability; at the same time, the calibration needle is fixed by bolt locking, making its position less prone to loosening, further ensuring the stability of the calibration benchmark, making each test result highly reliable, and providing a stable guarantee for construction quality.

[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0021] like Figures 1-6 As shown, a horizontal positioning calibrator for wall construction provided by this utility model includes a handle 1, a mounting platform 2 fixedly connected above the handle 1, an adjustment component 3 installed above the mounting platform 2, and a calibration component 4 installed on the mounting surface 31 of the adjustment component 3. The mounting platform 31 has a sliding groove 32 inside, and an adjusting screw 33 is threaded to the end of the mounting platform 31. The adjusting screw 33 passes through the sliding groove 32 and is threaded through the sliding plate 34. The sliding plate 34 is fixedly connected to the top of the mounting platform 2 and slides axially inside the sliding groove 32.

[0022] It should be noted that the adjusting screw 33 and the sliding plate 34 are threaded transmission structures. When the adjusting screw 33 rotates around its own axis, it drives the sliding plate 34 to slide axially along the slide groove 32 through the thread force. The sliding of the sliding plate 34 can synchronously drive the mounting platform 2 to adjust its position along the sliding direction of the sliding plate 34, thereby realizing the adjustment of the lateral positioning distance of the grip 1.

[0023] The specific technical solution involves the operator holding the handle 1 to control the entire device. By rotating the adjusting screw 33 in the adjusting assembly 3, the screw 33 engages with the sliding plate 34 via a threaded transmission structure, causing the sliding plate 34 to slide axially along the groove 32 inside the mounting platform 31. Since the sliding plate 34 is fixedly connected above the mounting platform 2, its sliding motion synchronously moves the mounting platform 2, adjusting the position of the handle 1 for easy gripping by the user.

[0024] The calibration assembly 4 includes a calibration needle 41, which is locked to the surface of the mounting platform 31 by bolts 42. A rotating plate 43 is movably connected to the upper surface of the mounting platform 31. The surface of the rotating plate 43 is provided with a scale 44. The scale 44 and the calibration needle 41 form a straight line, which is the calibration line 45. A tightening nut 46 is threadedly connected to the surface of the rotating plate 43. A calibration plate 47 is fixedly connected to the outer side of the rotating plate 43.

[0025] It should be noted that there are two sets of calibration components 4. One set of calibration components 4 is installed at the front end of the mounting platform 31, and the other set is installed at the middle position of the mounting platform 31.

[0026] Furthermore, when the nut 46 is screwed onto the surface of the rotating plate 43, the rotating plate 43 is not locked in place. Adjustable rotational damping is provided to the rotating plate 43, which enables the rotating plate 43 to maintain its current position when no external force is applied, and to rotate around its movable connection point with the mounting platform 31 when driven by an external force.

[0027] When the wall surface against which the calibration plate 47 is attached is not level, the calibration plate 47 is driven by the tilting force of the wall surface to rotate the rotating plate 43 synchronously, thereby causing the calibration needle 41 and the calibration line 45 to be relatively offset, so as to visually display the horizontal deviation of the wall surface.

[0028] Specifically, before testing, the damping is adjusted by tightening the nut 46 in the calibration assembly 4. The nut 46 is threaded onto the surface of the rotating plate 43, but does not lock the rotating plate 43 in place; instead, it provides adjustable rotational damping. This damping allows the rotating plate 43 to maintain its current position when no external force is applied, preventing positional shifts caused by slight equipment vibrations during testing. Simultaneously, it ensures that the rotating plate 43 can flexibly rotate around its movable connection point with the mounting platform 31 when driven by an external force, guaranteeing timely calibration response.

[0029] More specifically, during testing, the calibration plate 47 in the calibration assembly 4 is tightly fitted against the wall to be tested. If the wall is level, the calibration line 45 on the rotating plate 43 is aligned with the calibration needle 41, which is fixed to the mounting platform 31 by bolts 42. The absence of horizontal deviation can be confirmed by the scale 44 on the surface of the rotating plate 43. If the wall is not level, the inclined wall will exert a lateral force on the calibration plate 47. The calibration plate 47 will drive the rotating plate 43, which is fixedly connected to it, to rotate synchronously. At this time, the position of the calibration needle 41 remains unchanged, and the calibration line 45 on the rotating plate 43 will be offset relative to the calibration needle 41. The construction personnel can intuitively and accurately obtain the degree of horizontal deviation of the wall by reading the offset value on the scale 44, and complete the horizontal positioning calibration.

[0030] Working principle: Lateral positioning adjustment principle: The operator holds the handle 1 to control the entire equipment. By rotating the adjusting screw 33 in the adjusting assembly 3, the screw 33 and the sliding plate 34 are connected by a threaded transmission structure, causing the sliding plate 34 to slide axially along the groove 32 inside the mounting platform 31. Since the sliding plate 34 is fixedly connected above the mounting platform 2, the sliding of the sliding plate 34 will synchronously drive the mounting platform 2 to move, thereby adjusting the position of the handle 1 for easy gripping by the user.

[0031] Principle of horizontal deviation detection: Before testing, the damping is adjusted by tightening the nut 46 in the calibration assembly 4. The nut 46 is threaded onto the surface of the rotating plate 43, but does not lock the rotating plate 43 in place; instead, it provides adjustable rotational damping. This damping allows the rotating plate 43 to maintain its current position when no external force is applied, preventing positional shifts caused by slight equipment vibrations during testing. Simultaneously, it ensures that the rotating plate 43 can flexibly rotate around its movable connection point with the mounting platform 31 when driven by an external force, guaranteeing timely calibration response.

[0032] During testing, the calibration plate 47 in calibration assembly 4 is tightly fitted against the wall to be tested. If the wall is level, the calibration line 45 on the rotating plate 43 is aligned with the calibration needle 41, which is fixed to the mounting platform 31 by bolts 42. The absence of horizontal deviation can be confirmed by the scale 44 on the surface of the rotating plate 43. If the wall is not level, the inclined wall will exert a lateral force on the calibration plate 47. The calibration plate 47 will drive the rotating plate 43, which is fixedly connected to it, to rotate synchronously. At this time, the position of the calibration needle 41 remains unchanged, and the calibration line 45 on the rotating plate 43 will be offset relative to the calibration needle 41. The construction personnel can intuitively and accurately obtain the degree of horizontal deviation of the wall by reading the offset value on the scale 44, and complete the horizontal positioning calibration.
