Description

Technical Field

[0001] This application relates to the technical field of engineering cost estimation, and in particular to a multifunctional engineering cost estimation drawing measurement device. Background Technology

[0002] In cost estimation for various engineering projects, including construction, municipal engineering, and installation, drawing measurement is a crucial preliminary step for quantity calculation, cost accounting, and construction plan development. Staff must frequently perform high-precision measurements on various parameters in the drawings, such as line segment lengths, node spacing, and included angles, and record the measurement data accurately and in real time to ensure the reliability of subsequent cost calculations.

[0003] A search revealed that Chinese Patent Publication No. CN221882398U discloses a multifunctional engineering cost drawing measurement device, which includes an L-shaped support and a surveying mechanism. The surveying mechanism is arranged on the outside of the L-shaped support, and the surveying mechanism includes a measuring component arranged on one side of the L-shaped support. An auxiliary component is installed on the outside of the measuring component.

[0004] Regarding the aforementioned related technologies and existing similar devices, the inventors have discovered the following shortcomings: ordinary rulers only have basic length measurement functions, which are limited in functionality; although some existing multi-functional devices integrate multiple measurement modules, the measurement and recording processes are separated, requiring staff to use separate tools such as notebooks and pens to record data after measurement, which not only increases tool switching costs but also easily leads to mismatches between measurement data and corresponding points due to memory bias and recording delays; furthermore, when measuring multiple points, the lack of a stable synchronous positioning structure easily leads to data confusion and omissions, affecting the accuracy of cost calculations; at the same time, existing devices often suffer from problems such as inconvenient component disassembly, insufficient positioning accuracy, and limited ability to adapt to different specifications of drawings, making it difficult to meet the efficient measurement needs of complex engineering cost scenarios.

[0020] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0021] This application discloses a multifunctional engineering cost drawing measurement device. For example...

Lengths of 300mm, 500mm, and 1000mm are available, with a thickness of 5-10mm, balancing structural strength and portability. One side of the ruler 1 features graduation lines 2 along its length. These graduation lines are laser-etched and filled with wear-resistant ink, achieving a precision of 0.1mm to ensure clear legibility even after long-term use. An embedded protractor 18, made of acrylic, is fixed to one end of the ruler 1. The protractor has a measuring range of 0-180° and a precision of 0.5°, enabling accurate angle measurement. A flexible clamp-type pen holder 17 is fixed to the side of the ruler 1 furthest from the graduation lines 2. The clamping distance of the pen holder 17 is adjustable from 8-15mm to accommodate different pen sizes. At least one pointer plate 6 is detachably installed above the ruler 1. The pointer plate 6 is made of transparent PC material with a thickness of 2-3mm. The free end is set as a pointed structure to facilitate accurate pointing to the measurement point of the scale line 2. The transparent material can avoid obscuring the lines below the drawing.

[0022] See Figure 3 , Figure 4 As shown, a vertical rod 5 is fixedly installed at one end of the pointing plate 6. The vertical rod 5 is made of stainless steel with a passivated and rust-proof surface, and has a diameter of 8-12mm, balancing rigidity and rust resistance. A groove 3 is formed inside the ruler 1 along its length. Several through holes 4 are formed at the upper end of the ruler 1 along its length, communicating with the groove 3 and all being elongated. The lower end of the vertical rod 5 is slidably positioned within the groove 3, allowing it to move along the length of the groove 3 to accommodate measurement needs at different locations. A limiting component is provided at the lower end of the vertical rod 5, including a first protrusion 7 and a second protrusion 8. The first protrusion 7 and the second protrusion 8 are symmetrically fixedly connected to both sides of the lower end of the vertical rod 5 and are both perpendicular to the vertical rod 5. The first protrusion 7 and the second protrusion 8 are made of the same material as the vertical rod 5 and are integrally formed, resulting in a stable structure.

[0023] See Figure 4 , Figure 5As shown, the sidewall of the through hole 4 at the corresponding position of the first convex plate 7 has several grooves 9 of matching size, and the sidewall of the through hole 4 at the corresponding position of the second convex plate 8 has several grooves 10 of matching size. The length of the first convex plate 7 is 1.2-1.5 times the length of the second convex plate 8, and the width of the second convex plate 8 is 1.2-1.5 times the width of the first convex plate 7. The thickness of both the first and second convex plates is 1-2mm, and stable positioning is achieved through differential size design. The lower ends of the first convex plate 7 and the second convex plate 8 are provided with a 30-45° guide chamfer to facilitate insertion into the grooves. The grooves 9 and 10 are evenly distributed along the sidewall of the through hole 4, the distance between two adjacent grooves 9 and two adjacent grooves 10 is 10-20mm, and the depth of both grooves 9 and 10 is 2-3mm, allowing for flexible adjustment of the installation position and number of the guide plate 6.

[0024] See Figure 1 , Figure 2 , Figure 3 As shown, a fastening assembly is provided between the upper part of the vertical rod 5 and the ruler 1. The fastening assembly includes a fastening plate 11, which is sleeved on the vertical rod 5 and located between the pointer plate 6 and the ruler 1. The fastening plate 11 is threadedly connected to the vertical rod 5. The fastening plate 11 is made of ABS plastic and has anti-slip textures with a depth of 0.3-0.5mm evenly arranged on the outer circumference, which makes it easy to tighten by hand and achieve stable fixation of the pointer plate 6.

[0025] See Figure 3 , Figure 4 As shown, a recording component is detachably mounted on the upper end of the vertical rod 5. The recording component includes a pressing plate 12, a sticky note roll 16, and a connecting shaft 13. Both the pressing plate 12 and the connecting shaft 13 are made of ABS plastic. A locking block 14 is fixedly mounted below the pressing plate 12. The locking block 14 is made of elastic PP plastic and has good elastic deformation capability. The locking block 14 and the pressing plate 12 are fixedly connected by the connecting shaft 13. The locking block 14 and the connecting shaft 13 pass through one end of the sticky note roll 16. The sticky note roll 16 is made of tearable waterproof paper and can rotate freely when fitted onto the connecting shaft 13. A slot 15 is provided on the upper end of the vertical rod 5 at the corresponding position of the locking block 14. The locking block 14 and the slot 15 are elastically engaged to facilitate the replacement and fixation of the sticky note roll 16.

[0026] The implementation principle of the multifunctional engineering cost drawing measurement device in this application is as follows: Component Installation: When installing the guide plate 6, align the protrusions 7 and 8 at the lower end of the vertical rod 5 with the corresponding grooves 9 and 10 on the side wall of the through hole 4. Use the guide chamfer at the lower end of the protrusions to assist insertion, allowing the lower end of the vertical rod 5 to extend into the slide groove 3. Rotate the guide plate 6 to rotate the vertical rod 5 and protrusions 7 and 8 synchronously, causing the protrusions to misalign with their corresponding grooves. The difference in size between protrusions 1 and 2 provides a limiting effect, preventing the vertical rod 5 from detaching from the ruler 1. If multiple guide plates 6 need to be installed, repeat the above operation using different groove groups, adjusting the guide plate spacing according to measurement requirements. For disassembly, rotate the guide plate 6 in the opposite direction to align the protrusions with the grooves, then pull out the vertical rod 5 and the guide plate 6.

[0027] Measurement and positioning: Move the guide plate 6 along the slide 3 according to the measurement point. When the pointed free end of the guide plate 6 accurately points to the target point of the scale line 2, rotate the fastening plate 11 clockwise to make the fastening plate 11 fit tightly against the upper surface of the ruler 1, and fix the guide plate 6 stably to avoid displacement during the measurement process. If it is necessary to measure the angle, the target angle data can be directly read through the protractor 18 at one end of the ruler 1.

[0028] Data recording: After the measurement is completed, the writing pen placed on the pen holder 17 can be used to record the measurement points, data and related notes on the sticky note roll 16 of the corresponding pointing plate 6, so as to realize the synchronization of measurement and recording. When the sticky note roll 16 is used up or needs to be replaced, press the pressing plate 12 to make the elastic block 14 disengage from the slot 15, and the recording component can be removed to replace the sticky note roll 16. After the replacement is completed, align the block 14 with the slot 15 and press it to realize the elastic snap-fit ​​fixation.

[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
