Description

Technical Field

[0001] This utility model belongs to the field of measuring ruler technology, specifically relating to a measuring ruler for engineering supervision. Background Technology

[0002] A measuring ruler is a tool used in engineering to measure the levelness and verticality of walls. It is widely used in the construction of buildings and structures for measurement.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN221975963U discloses "an engineering measuring ruler", which includes a drum; a reset member is rotatably connected inside the drum, and a measuring tape wound around the outer periphery of the reset member is connected to the outer periphery of the reset member. An opening for the measuring tape to enter and exit is opened on the outer periphery of the drum, and a cleaning cover is installed on the outer periphery of the drum. A cleaning channel is opened inside the cleaning cover and communicates with the opening. The measuring tape passes through the opening and the cleaning channel. A brush for cleaning the surface of the measuring tape is rotatably connected inside the cleaning cover, and the reset member and the brush are connected by a linkage.

[0004] While existing measuring rulers can clean the measuring tape using rotating brushes—a structure driven by a linkage that allows the brushes inside the cleaning cover to rotate during measurement and return—effectively removing concrete and sewage from the measuring tape's surface, maintaining its flatness and clarity, and thus improving measurement accuracy, the fixed rotating connection between the brush handle and the cleaning cover means that once the brush bristles wear down, the entire cleaning cover needs to be replaced. This maintenance method significantly increases maintenance costs and is not conducive to the long-term, efficient use of the measuring ruler.

[0005] To address the aforementioned issues, this application proposes a measuring ruler for engineering supervision. Utility Model Content

[0027] In this invention, the limiting components allow for convenient and detachable installation of the first and second mounting plates onto the first and second L-shaped support frames. This facilitates the installation and replacement of the first and second brushes, avoiding the need to replace the entire cleaning structure due to brush wear, reducing maintenance costs, and improving the efficiency of the measuring ruler. Furthermore, the first and second brushes clean the outer wall of the measuring ruler when it is retracted, preventing residual dirt and ensuring the flatness and clarity of the measuring ruler surface. This also prevents impurities from entering the measuring ruler body, thereby improving the accuracy of the measurement results.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example

[0038] Please see Figures 1-5 This utility model provides the following technical solution: a measuring ruler for engineering supervision, including a measuring tape body 1, with mounting brackets 2 symmetrically fixed on both sides of the measuring tape body 1, and a first L-shaped support bracket 3 and a second L-shaped support bracket 4 respectively fixedly connected to the two mounting brackets 2; a first mounting plate 9 is provided on the first L-shaped support bracket 3, and a first brush 12 is provided on the first mounting plate 9; a second mounting plate 10 is provided on the second L-shaped support bracket 4, and a second brush 13 is provided on the second mounting plate 4; it also includes two sets of limiting components, respectively disposed on the first L-shaped support bracket 3 and the second L-shaped support bracket 4, for detachably installing the first mounting plate 9 on the first L-shaped support bracket 3, and for... The second mounting plate 10 is detachably mounted on the second L-shaped support frame 4. When the measuring ruler is pulled out for use, the first mounting plate 9 and the second mounting plate 10 can be respectively mounted on the first L-shaped support frame 3 and the second L-shaped support frame 4 through the limiting component, so that the first brush 12 and the second brush 13 respectively adhere to both sides of the outer wall of the measuring ruler. When the measuring ruler is retracted after measurement, if the outer wall of the measuring ruler is contaminated with concrete, sewage or other substances, the first brush 12 and the second brush 13 will clean it to avoid residual stains on the outer wall of the measuring ruler, ensure the flatness and clarity of the measuring ruler surface, and thus improve the accuracy of the measurement results.

[0039] Preferably, by Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the limiting component includes two flip plates 6, which are connected to the corresponding first L-shaped support frame 3 and second L-shaped support frame 4 via a rotating structure. Two symmetrical support plates 15 are fixed to one side of the flip plate 6, and a fixing rod 16 is fixed between the two support plates 15. A torsion spring 17 is sleeved on the fixing rod 16, and the two ends of the torsion spring 17 abut against the outer surface of the measuring tape body 1 and the side of the flip plate 6, respectively. When it is necessary to install the first mounting plate 9 and the second mounting plate 10, the flip plate 6 can be flipped to one side, so that the flip plate 6 can rotate on the first L-shaped support frame 3 and the second L-shaped support frame 4 via the rotating structure. When flipped over, the torsion spring 17 deforms and generates elastic force. Then, the first mounting plate 9 and the second mounting plate 10 are placed on the corresponding first L-shaped support frame 3 and the second L-shaped support frame 4, respectively. Under the action of the elastic force of the torsion spring 17, the flipping plate 6 automatically resets and squeezes and limits the first mounting plate 9 and the second mounting plate 10. At the same time, one side of the first mounting plate 9 and the second mounting plate 10 will abut against the extended part of the first L-shaped support frame 3 and the second L-shaped support frame 4, thereby restricting the horizontal movement of the first mounting plate 9 and the second mounting plate 10, making the first mounting plate 9 and the second mounting plate 10 more securely installed.

[0040] When it is necessary to disassemble and replace the first mounting plate 9 and the second mounting plate 10, it is only necessary to flip the flip plate 6 to one side. At this time, the torsion spring 17 deforms and generates elastic force, and the flip plate 6 separates from the first mounting plate 9 and the second mounting plate 10. Then, the first mounting plate 9 and the second mounting plate 10 can be removed from the first L-shaped support frame 3 and the second L-shaped support frame 4, and then the first brush 12 and the second brush 13 on the first mounting plate 9 and the second mounting plate 10 can be replaced. The operation is simple and quick, effectively avoiding the problem of having to replace the entire cleaning structure due to the wear of the brush bristles, thereby reducing maintenance costs and improving the efficiency of the measuring ruler.

[0041] Preferably, by Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the rotating structure includes: a pair of fixing blocks 18 respectively fixed to the first L-shaped support frame 3 and the second L-shaped support frame 4; rectangular holes 19 opened on the two fixing blocks 18; connecting rods 20 fixed to both sides of the flip plate 6; the connecting rods 20 are inserted into the rectangular holes 19, and the connecting rods 20 can move along the length direction of the rectangular holes 19; through the rotating structure, the flip plate 6 can be smoothly flipped on the first L-shaped support frame 3 and the second L-shaped support frame 4, and the movement of the connecting rods 20 in the rectangular holes 19 also ensures the stability of the flip plate 6 during flipping. The length of the rectangular holes 19 is reasonably designed, which allows the flip plate 6 to have enough flipping space and ensures the stability of the flip plate 6 during flipping, avoiding difficulties in installing or disassembling the first mounting plate 9 and the second mounting plate 10 due to unstable flipping.

[0042] Preferably, by Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the flip plate 6 has clearance openings 21 on both sides, and the length of the clearance openings 21 is greater than the length of the fixing block 18. By setting the clearance openings 21, when the flip plate 6 is flipped, the clearance openings 21 can provide enough space for the fixing block 18, avoiding interference between the flip plate 6 and the fixing block 18, thereby ensuring the smoothness of the flip plate 6 flipping, and further improving the convenience of installing or removing the first mounting plate 9 and the second mounting plate 10.

[0043] Preferably, by Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, dovetail grooves 8 are provided on one side of both flip plates 6, and dovetail sliders 11 that cooperate with the dovetail grooves 8 are provided on one side of both the first mounting plate 9 and the second mounting plate 10. When installing the first mounting plate 9 and the second mounting plate 10, the dovetail sliders 11 on the first mounting plate 9 and the second mounting plate 10 can be inserted into the dovetail grooves 8 on the two flip plates 6 respectively. Then, when the flip plates 6 are flipped and reset, they will squeeze and limit the first mounting plates 9 and the second mounting plates 10. Through the cooperation of the dovetail grooves 8 and the dovetail sliders 11, the first mounting plates 9 and the second mounting plates 10 can remain stable when squeezed by the flip plates 6, and are not easy to shake or fall off, which further improves the stability of the installation of the first mounting plates 9 and the second mounting plates 10.

[0044] Preferably, by Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the length of the first L-shaped support frame 3 is greater than the length of the flip plate 6, and the length of the flip plate 6 is the same as the length of the first mounting plate 9 and the second mounting plate 10. This design ensures that the flip plate 6 is not interfered with by the first L-shaped support frame 3 when flipping, and at the same time, the flip plate 6 can completely cover the first mounting plate 9 and the second mounting plate 10, ensuring the stability of the compression limit. In addition, the fact that the length of the flip plate 6 is the same as the length of the first mounting plate 9 and the second mounting plate 10 also ensures that the first mounting plate 9 and the second mounting plate 10 can be completely attached to the first L-shaped support frame 3 and the second L-shaped support frame 4 during installation, further improving the stability of the installation.

[0045] Preferably, by Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, a support column 5 is fixed between the first L-shaped support frame 3 and the second L-shaped support frame 4; the setting of the support column 5 further enhances the structural stability between the first L-shaped support frame 3 and the second L-shaped support frame 4, making the entire measuring ruler more stable and reliable in use.

[0046] Both the first L-shaped support frame 3 and the second L-shaped support frame 4 have arc-shaped openings 14 on their sides; the arc-shaped openings 14 make it easier for the operator to flip the flip plate 6 with their fingers, thus improving the convenience of operation.

[0047] Components not described in detail in this article are existing technologies.

[0048] The working principle and usage process of this utility model are as follows: When in use, the operator first inserts his finger into the arc-shaped opening 14 on the side of the first L-shaped support frame 3 and the second L-shaped support frame 4 and flips the flip plate 6 to one side. During the flipping process, the connecting rods 20 on both sides of the flip plate 6 will move and rotate along the length direction of the rectangular hole 19 on the fixing block 18. At the same time, the clearance openings 21 on both sides of the flip plate 6 provide sufficient space for the fixing block 18 to avoid interference between the two and ensure smooth flipping. At this time, the torsion spring 17 on the fixing rod 16 between the support plates 15 on one side of the flip plate 6 deforms and generates elastic force.

[0049] Next, the dovetail sliders 11 on one side of the first mounting plate 9 and the second mounting plate 10 are respectively inserted into the dovetail grooves 8 on the two flip plates 6, and the first mounting plate 9 and the second mounting plate 10 are respectively placed on the corresponding first L-shaped support frame 3 and the second L-shaped support frame 4. Then, the flip plate 6 is released, and under the action of the torsion spring 17, the flip plate 6 automatically resets, squeezing and limiting the first mounting plate 9 and the second mounting plate 10. At the same time, one side of the first mounting plate 9 and the second mounting plate 10 abuts against the extended part of the first L-shaped support frame 3 and the second L-shaped support frame 4, restricting their movement in the horizontal direction, thus completing the installation.

[0050] Afterwards, the staff can pull out the measuring tape body 1 to perform the measurement operation. When the measuring tape is retracted after the measurement is completed, if the outer wall of the measuring tape is contaminated with concrete, sewage or other substances, the first brush 12 on the first mounting plate 9 and the second brush 13 on the second mounting plate 10 will clean the two sides of the outer wall of the measuring tape in close contact to avoid stains and ensure the flatness and clarity of the measuring tape surface. This not only prevents impurities from entering the interior of the measuring tape body 1, but also improves the accuracy of the measurement results.

[0051] When the first brush 12 and the second brush 13 become worn and need to be replaced, the operator flips the flip plate 6 to one side through the arc-shaped opening 14 to separate the flip plate 6 from the first mounting plate 9 and the second mounting plate 10. Then, the first mounting plate 9 and the second mounting plate 10 are removed from the first L-shaped support frame 3 and the second L-shaped support frame 4 for replacement. The installation can be reinstalled according to the above installation steps. The operation is simple and quick, effectively reducing maintenance costs and improving the efficiency of the measuring ruler.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
