Description

Technical Field

[0001] This utility model relates to the field of building construction surveying tools, and in particular to a masonry tool ruler for controlling the angle of brick walls. Background Technology

[0002] In construction engineering, controlling the angles of corners, slopes, and curved sections of brick walls has always been a challenging aspect of construction. Traditional methods often rely on plumb bobs and measuring tapes, which are not only cumbersome but also require at least two people working together, resulting in low efficiency. To improve efficiency and adaptability, tool rulers are now widely used. This tool typically consists of a main ruler and a secondary ruler that rotates within the main ruler. The angle between the secondary ruler and the main ruler is determined by rotating the secondary ruler. However, this type of tool ruler has a significant drawback: the secondary ruler is difficult to lock effectively after rotation, easily causing wobbling, leading to deviations in angle measurement, and ultimately affecting the accuracy and quality of masonry work. Utility Model Content

[0003] In order to overcome the shortcomings of existing technologies, this utility model provides a masonry tool ruler for controlling the angle of brick walls.

[0004] The technical solution of this utility model is as follows: A masonry tool ruler for controlling the angle of a brick wall includes: a main ruler and a secondary ruler, wherein the secondary ruler is rotatably disposed inside the main ruler, and the secondary ruler is provided with an angle locking mechanism for locking the angle of the secondary ruler after it has rotated inside the main ruler.

[0005] Preferably, the main ruler has a receiving cavity for accommodating the secondary ruler. The top and bottom side walls of the receiving cavity are each provided with a rotating cavity at intervals. The top and bottom of the secondary ruler are each provided with a rotating component at intervals, and each rotating component is rotatably disposed in its corresponding rotating cavity.

[0006] Preferably, each of the rotating cavities is spaced around the top and bottom sidewalls of the receiving cavity, and each of the rotating components is spaced around the top and bottom of the subscale.

[0007] Preferably, the vertical cross-sectional shape of the rotating component is spherical, and the shape of the rotating cavity is adapted to the shape of the rotating component.

[0009] Preferably, the ratchet has 72 teeth.

[0010] Preferably, the angle locking mechanism further includes: a knob and a locking block, the locking block being disposed in the mounting cavity and movably abutting against the locking block; the top surface of the main scale has a first through hole communicating with the mounting cavity, and one end of the knob enters the mounting cavity through the first through hole and is detachably connected to the locking block.

[0011] Preferably, a scale is provided around the top surface of the main scale, a second through hole is provided on the top surface of the main scale, a connecting rod is fixedly provided on the top surface of the ratchet, the connecting rod passes through the second through hole and exits the mounting cavity, and a pointer is fixedly provided on the connecting rod.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments: like Figure 1 , Figure 2 and Figure 5 As shown, a masonry tool ruler for controlling the angle of a brick wall includes a main ruler 10 and a secondary ruler 20, wherein the secondary ruler 20 is rotatably disposed inside the main ruler 10. Specifically, a receiving cavity 11 is formed inside the main ruler 10, and rotating cavities 13 are spaced apart on the top and bottom side walls of the receiving cavity 11. Rotating members 21 are spaced apart on the top and bottom of the secondary ruler 20, and each rotating member 21 is rotatably disposed within its corresponding rotating cavity 13. Through the above arrangement, the secondary ruler 20 can rotate within the rotating cavities 13 via the rotating members 21. During rotation, the receiving cavity 11 can also accommodate the secondary ruler 20. The number of rotating members 21 at the top and bottom of the secondary ruler 20 and the number of rotating cavities 13 on the top and bottom side walls of the receiving cavity 11 are both two, all horizontally spaced apart.

[0019] Among them, such as Figure 5 As shown, the vertical cross-sectional shape of the rotating component 21 is spherical, and the shape of the rotating cavity 13 is adapted to the shape of the rotating component 21. This arrangement increases the rotational resistance of the rotating component 21 within the rotating cavity 13.

[0020] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the auxiliary ruler 20 is provided with an angle locking mechanism, which includes a ratchet 22, a locking block 24, and an elastic element 23. To facilitate the installation of the ratchet 22, an installation cavity 12 is provided on the top side wall of the receiving cavity 11. One end of the elastic element 23 is fixedly connected to the side wall of the installation cavity 12, and the other end of the elastic element 23 is connected to the locking block 24. The elastic element 23 is a spring. The ratchet 22 is fixedly connected to the top surface of the auxiliary ruler 20, and the ratchet 22 is located inside the installation cavity 12. When the auxiliary scale 20 is rotated, the ratchet 22 rotates along with it. During this process, the teeth of the ratchet 22 press against the locking block 24, causing the locking block 24 to move closer to the side wall of the mounting cavity 12, and the elastic element 23 is compressed. After the teeth of the ratchet 22 have rotated past the locking block 24, the locking block 24 is no longer compressed. When the elastic element 23 returns to its original position, it drives the locking block 24 to return to its original position. The locking block 24 then engages with the teeth of the ratchet 22, thereby locking the angle of the auxiliary scale 20 after rotation. It should be noted that the auxiliary scale 20 can only be rotated clockwise within the rotating cavities 13 using the rotating parts 21. If the locking block 24 is rotated counterclockwise, it will jam the teeth of the ratchet 22, preventing the auxiliary scale 20 from rotating, thus improving the stability of the auxiliary scale 20 during rotation. Rotating the auxiliary scale 20 clockwise by 360° will return it to its original position.

[0021] To further improve the locking effect of locking block 24, such as Figure 1 , Figure 3 and Figure 4 As shown, the angle locking mechanism further includes a knob 25 and a locking block 26. The locking block 26 is disposed within the mounting cavity 12 and movably abuts against the locking block 24. A first through hole 15 communicating with the mounting cavity 12 is provided on the top surface of the main scale 10. One end of the knob 25 enters the mounting cavity 12 through the first through hole 15 and is detachably connected to the locking block 26. By rotating the knob 25, the knob 25 can drive the locking block 26 to rotate. It should be noted that the locking block 26 has two states, one being the initial state, such as... Figure 3 As shown, at this time, there is a gap between the locking block 26 and the locking block 24. The locking block 26 is vertically positioned within the mounting cavity 12 and will not interfere with the movement of the locking block 24. State two is the working state of the locking block 26, as shown... Figure 4As shown, rotating the knob 25 causes the locking block 26 to rotate clockwise, making the locking block 26 abut against the locking block 24. When the teeth of the ratchet 22 press against the locking block 24, the locking block 24 cannot move towards the side wall of the mounting cavity 12, and the locking block 24 cannot compress the elastic element 23, making the auxiliary ruler 20 unable to rotate, thereby further improving the locking effect of the locking block 24. The locking block 26 is provided with a threaded hole, and the knob 25 is provided with an external thread. After the knob 25 is inserted into the mounting cavity 12, the external thread of the knob 25 is screwed into the threaded hole, realizing a detachable connection between the two. It should be noted that the knob 25 is a rotary switch, a common structure used by those skilled in the art, such as the rotary switch in patent application number 202422348495.9. Of course, other rotary switches that can achieve the above functions can also be used. Therefore, the function and structure of the knob 25 will not be described in detail.

[0022] To facilitate viewing the angle after the vernier scale 20 is rotated, such as Figure 1 , Figure 2 and Figure 5 As shown, a scale 19 is provided around the top surface of the main scale 10. A second through hole 16 is provided on the top surface of the main scale 10. A connecting rod 17 is fixedly provided on the top surface of the ratchet 22. The connecting rod 17 passes through the second through hole 16 and exits the mounting cavity 12. A pointer 18 is fixedly provided on the connecting rod 17. When the secondary scale 20 drives the ratchet 22 to rotate, it synchronously drives the pointer 18 to rotate within the second through hole 16, so that the pointer 18 is positioned on the scale 19, thereby allowing direct reading of the rotation angle of the secondary scale 20.

[0023] Specifically, the ratchet 22 has 72 teeth, which can limit the rotation step angle of the vernier scale 20 to within 5°, thus effectively improving the accuracy of angle measurement.

[0024] In this embodiment, as Figure 2 As shown, a laser marking module 30 is provided at one end of the auxiliary ruler 20, and a control switch 31 electrically connected to the laser marking module 30 is provided on one side of the auxiliary ruler 20. Specifically, when the control switch 31 is turned on, the laser marking module 30 starts working and projects a measurement mark to accurately guide angle measurement and reduce manual line drawing. The use of the laser marking module 30 in conjunction with the switch is a common practice among those skilled in the art; therefore, its structure and principle will not be described in detail.

[0025] In this embodiment, a level bubble is provided in the middle of the top surface of the main ruler 10. This design integrates the level detection function into the tool ruler itself. By directly observing the state of the level bubble when the main ruler 10 is placed on the wall, it can be determined whether the wall is level, thereby reducing the number of tools that workers need to carry.

[0026] In this embodiment, the main ruler 10 has a length of 640 mm ± 2 mm, and bidirectional millimeter scales are provided on both sides of the top surface of the main ruler 10 for measuring the length of the bricks needed during the masonry process; the secondary ruler 20 has a length of 620 mm ± 2 mm; both the main ruler 10 and the secondary ruler 20 are made of aluminum alloy, and their surfaces are anodized to enhance their oxidation resistance. Example 2

[0027] Unlike Embodiment 1, each of the rotating cavities 13 is spaced around the top and bottom sidewalls of the receiving cavity 11, and each of the rotating members 21 is spaced around the top and bottom of the secondary ruler 20. There are eight rotating members 21 and eight rotating cavities 13. Four rotating members 21 and four rotating cavities 13 are respectively softly wrapped around the top surface of the secondary ruler 20 and the top sidewall of the receiving cavity 11, and the remaining four rotating members 21 and four rotating cavities 13 are respectively wrapped around the bottom surface of the secondary ruler 20 and the bottom sidewall of the receiving cavity 11. This increases the number of rotating slots and rotating member pairs 21, thereby improving the smoothness of rotation between the secondary ruler 20 and the main ruler 10.

[0028] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0029] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
