Description

Technical Field

[0001] This utility model relates to the field of flatness testing, and in particular to an auxiliary tool for brick construction. Background Technology

[0002] Ensuring the flatness of the tiled surface is a crucial quality control step during brickwork installation. Existing flatness testing methods mainly include using tools such as rulers, spirit levels, or laser levels. Among these, rulers and spirit levels, as traditional testing methods, are simple to operate but have significant drawbacks: their accuracy relies on manual visual inspection, making it difficult to capture subtle variations in the brick surface. Especially when working on large areas, repeated tool movements are necessary, resulting in low efficiency and a high risk of missed detections. While laser levels offer high accuracy, they are expensive, complex to operate, and sensitive to lighting and dust conditions in the construction environment, making them unsuitable for rapid on-site testing.

[0003] Furthermore, while existing mechanical inspection tools can improve inspection efficiency to some extent, they generally suffer from problems such as complex structure, bulky size, and inconvenience in carrying. At the same time, these tools often lack intuitive real-time feedback mechanisms, requiring construction personnel to rely on experience to determine the inspection results, making it impossible to quickly and accurately locate uneven areas.

[0024] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0026] Reference Figure 1 This embodiment provides an auxiliary tool for brick construction, including a straight long rod 1 and a flatness measuring component 2 that can slide along the length of the long rod 1 and is used to detect the flatness of the surface of the object to be tested after the bricks are laid.

[0027] Specifically, the flatness measuring component 2 includes a slider 21 slidably disposed on one side of the long rod 1. The slider 21 has a sliding cavity 211 whose extension direction is perpendicular to the length direction of the long rod 1, and an inlet 212 disposed in the extension direction of the sliding cavity 211 and intersecting the sliding cavity 211.

[0028] Furthermore, a detection element 22 is provided inside the sliding cavity 211, which can slide along the extension direction of the sliding cavity 211. One end of the detection element 22 passes through the inlet / outlet 212, and a spring 23 is provided between the other end of the detection element 22 and the opposite surface of the sliding cavity 211.

[0029] In summary, when detecting the surface flatness of an object, the long rod 1 is positioned parallel to the surface of the object being tested above the flatness detection surface. The extension direction of the sliding cavity 211 is perpendicular to the surface of the object being tested. The detection element 22 is in a retracted state, and one end of the detection element 22 penetrating the inlet / outlet 212 is perpendicularly abutted against the surface of the object being tested. Furthermore, by controlling the sliding element 21 to slide along the length of the long rod 1, the change in the length of the portion of the detection element 22 extending outside the inlet / outlet 212 is observed. This change serves as the basis for determining whether the surface of the object being tested is flat. That is, when the sliding element 21 slides along the length of the long rod 1 to a protrusion on the surface of the object being tested, the detection element 22 is squeezed by the protrusion on the detection surface. The pressure further contracts into the sliding cavity 211, that is, when a protrusion is detected on the flatness detection surface of the object to be tested, the portion of the detection element 22 extending out of the inlet 212 shortens; while when the sliding element 21 slides along the length of the long rod 1 to the depression on the flatness detection surface of the object to be tested, since the detection element 22 is in a contracted state in the initial state, that is, in the initial state, the spring 23 is already compressed, therefore, when the sliding element 21 slides to the depression on the detection surface, the detection element 22 is further extended out of the sliding cavity 211 by the thrust generated by the recovery of the spring 23, that is, when a depression is detected on the flatness detection surface of the object to be tested, the portion of the detection element 22 extending out of the inlet 212 grows.

[0030] In some embodiments, the long rod 1 has through holes 11 arranged parallel to the extension direction of the sliding cavity 211 along its length. A damping slider 3 is disposed inside the through holes 11, and the surface of the damping slider 3 has display lines 31 arranged parallel to the length direction of the long rod 1. The frictional force generated by the contact between the damping slider 3 and the side wall of the through hole 11 is greater than its own weight, and it can maintain balance when not subjected to external forces other than gravity.

[0031] Furthermore, the long rod 1 has a through groove 12 that is perpendicular to the length direction of the long rod 1. The length of the through groove 12 covers the entire sliding path of the slider 21. The slider 21 and the damping slider 3 are respectively arranged on both sides of the opening of the through groove 12. On the side of the slider 21 opposite to the damping slider 3, there is a long slot hole 213 that communicates with the sliding cavity 211. The length direction of the long slot hole 213 is parallel to the extension direction of the sliding cavity 211. On the side of the detection element 22 opposite to the long slot hole 213, there is a lifting element 24 that communicates with the long slot hole 213.

[0032] Furthermore, a lifting channel 32 is provided on the side of the damping slider 3 opposite to the sliding member 21; one end of the lifting member 24 extending out of the long slot 213 extends into the lifting channel 32 and can abut against the two opposite surfaces of the lifting channel 32 to lift or press down the damping slider 3.

[0033] In summary, the display lines 31 on the damping sliders 3 arranged on one side of the long rod 1 continuously form a baseline for judging flatness. As the slider 21 slides on the long rod 1, when the slider 21 slides to the protrusion on the detection surface, the detection element 22 retracts into the sliding cavity 211, causing the lifting element 24 to rise. At this time, the lifting element 24 abuts against the contact surface on the lifting channel 32. As the lifting element 24 rises, it will further push the damping slider 3 to rise, that is, the corresponding display line 31 rises. Similarly, when the slider 21 slides to the recess on the detection surface, the detection element 22 is pushed outward from the sliding cavity 211 by the spring 23, causing the lifting element 24 to fall. At this time, the lifting element 24 abuts against the lower contact surface of the lifting channel 32. As the lifting element 24 falls, it will further push the damping slider 3 to fall, that is, the corresponding display line 31 falls. The construction worker only needs to observe the height of the display line 31 on the damping slider 3 arranged on one side of the long rod 1 after inspecting the corresponding test line of the entire long plate to find the corresponding depressions and protrusions on the test surface.

[0034] In some embodiments, the lifting channel 32 includes a positioning section 321 arranged parallel to the length direction of the long rod 1, and a lifting section 322 symmetrically arranged on both sides of the positioning section 321 and in a trumpet shape. The lifting member 24 has a curved surface 241 disposed within the lifting channel 32 and capable of abutting against two opposing surfaces of the lifting channel 32.

[0035] It is worth noting that the distance between the two opposing surfaces of the positioning section 321 corresponding to the lifting channel 32 should be equal to the diameter of the curved surface 241 of the lifting member 24. Both sides of the positioning section 321 corresponding to the lifting channel 32 are provided with flared, outwardly opening lifting sections 322. When the sliding member 21 moves from one end of the long plate to the other, the lifting member 24 can smoothly pass through the two lifting channels 32 as it moves between two adjacent damping sliders 3. During the movement of the lifting member 24 within the lifting channel 32, the lifting member 24 can rotate under the frictional action of the contact between the curved surface 241 and the sidewall of the lifting channel 32.

[0036] In some embodiments, one end of the damping slider 3 has an inclined surface 33 and a wedge 4 that slides and fits against the inclined surface 33. The inclined surface 33 of the damping slider 3 has a screw hole 331 and an adjusting bolt 5 is threadedly connected to it. The extension direction of the screw hole 331 is parallel to the sliding direction of the damping slider 3. The wedge 4 has a circular hole 41 that passes through the screw hole 331 and has an end face diameter larger than the end face diameter of the screw hole 331. The adjusting bolt 5 passes through the circular hole 41 and is threadedly connected to the screw hole 331.

[0037] Specifically, the head of the adjusting bolt 5 abuts against the upper surface of the wedge 4. During use, the adjusting bolt 5 is screwed down to press the head of the adjusting bolt 5 against the wedge 4. Furthermore, the wedge 4 engages with the inclined surface 33 of the damping slider 3. When the wedge 4 is pressed by the head of the adjusting bolt 5, guided by the inclined surface 33 of the damping slider 3, the wedge 4 will produce a displacement perpendicular to the adjusting bolt 5, thus increasing the overall width of the wedge 4 and the damping slider 3. This makes the contact between the damping slider 3 and the sidewall of the through hole 11 more compact, thereby increasing the friction between the damping slider 3 and the through hole 11. Through these operations, in actual use, the friction between the damping slider 3 and the through hole 11 can be adjusted by screwing down the adjusting bolt 5, ensuring that the damping slider 3 can maintain balance without the action of external forces other than gravity.

[0038] In some embodiments, a movable bead 25 is provided at one end of the detection element 22 that passes through the inlet / outlet 212. The movable bead 25 changes the contact friction between the detection element 22 and the detection surface of the object to be measured from sliding friction to rolling friction, reducing frictional resistance, reducing wear on the detection element 22, and making the movement of the sliding element 21 easier during detection. Furthermore, the smaller contact area improves measurement accuracy.

[0039] In some embodiments, the long rod 1 has an anti-detachment groove 13 arranged parallel to the length direction, and the sliding member 21 has an anti-detachment part 26 that extends into the anti-detachment groove 13 at one end and is hook-shaped.

[0040] In some embodiments, a support assembly 6 is also included, symmetrically arranged at both ends of the long rod 1. The support assembly 6 includes a support 61 and a connecting rod 62 disposed between the support 61 and the long rod 1. It is worth noting that when the spring 23 is fully extended, the end of the detection element 22 extending out of the inlet 212 should be lower than the bottom surface of the support 61. This ensures that when the surface of the object to be tested is flat, the support 61 is placed on the flatness detection surface of the object to be tested, and the end of the detection element 22 extending out of the inlet 212 can contact the flatness detection surface of the object to be tested, thus compressing the spring 23.

[0041] In practical applications, unevenness on the surface of the object under test is often not due to brick quality issues (i.e., defects in the brick itself, resulting in substandard surface flatness), but rather to uneven thickness of the cement filling between the brick and the object under test, causing one side of the brick to be higher than the other. This device can also detect unevenness on the surface of the object under test caused by this situation. Specifically, it can determine the higher or lower side of the brick by observing whether the part of the detection element 22 extending outside the inlet / outlet 212 is continuously increasing or decreasing, or by observing whether the display line 31 on the continuous damping slider 3 is continuously rising or falling.

[0042] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
