Description

Technical Field

[0001] This utility model relates to the field of concrete mold measurement technology, specifically a multifunctional concrete mold size measurement tool. Background Technology

[0002] In existing technologies, the use of ordinary vernier calipers or depth gauges for dimensional calibration of concrete molds has the following limitations: For the four sides and diagonals of the bottom cavity of the mold, the extremely narrow operating space and the inability of the measuring claws to effectively extend and position themselves make the measurement process difficult and result in poor reading stability. Furthermore, traditional measuring tools are easily affected by residual concrete particles within the mold, impacting the accuracy of the measurement reference surface. Visual readings are also highly susceptible to introducing human error in poorly lit curing rooms.

[0003] Therefore, this utility model proposes a multifunctional concrete mold size measuring tool. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional concrete mold size measuring tool to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a multifunctional concrete mold size measuring tool, including a column located inside the mold, multiple fixed cylinders on the side of the column, sliding rods inside the fixed cylinders, and a measuring component inside the column that simultaneously pushes the multiple sliding rods out of the fixed cylinders.

[0005] Preferably, the measuring component includes an electric push rod located inside the column. The bottom end of the electric push rod is provided with a plate body one, and the other end is fixedly connected to the inner wall of the column. The bottom of the plate body one is provided with a vertical rod, and the outer wall of the vertical rod is provided with a plate body two. The cavity from the plate body two to the end of the slide rod is filled with liquid and maintained in a negative pressure state.

[0006] Preferably, the column has a fixing plate inside, and an air cavity is formed between the fixing plate and the plate body. The air in the air cavity is automatically filled by an air valve. The end of the slide rod has a chamber, which is connected to the air cavity between the fixing plate and the plate body through an air pipe.

[0007] Preferably, the end of the slide bar is sharp.

[0008] Preferably, the bottom of the slide bar is provided with a support column and is fixedly connected to it.

[0009] Preferably, the top of the column is provided with a handle.

[0010] This utility model has at least the following beneficial effects: In this invention, the measuring component pushes the sliding rods out of the fixed cylinder, allowing multiple sliding rods to slide out simultaneously, enabling rapid measurement of the internal dimensions of the mold. Simultaneously, as the plate moves downwards, air in the air cavity between the fixed plate and the plate is pushed out by the plate and enters the chamber at the end of the sliding rod through an air pipe. The expelled gas blows across the mold surface to be contacted, cleaning away residual concrete particles and other debris, ensuring the accuracy of the measurement reference plane. The sharp end of the sliding rod adapts to the narrow space of the mold, accurately reaching the inner wall. The support column at the bottom of the sliding rod prevents the measuring tool from tilting, ensuring reliable measurement results. This tool is minimally affected by residual concrete particles inside the mold, ensuring accurate measurement reference planes, reducing human error, and is suitable for environments with poor lighting. Furthermore, adjusting the extension length of the sliding rods allows for adaptation to molds of different sizes, demonstrating strong versatility and practicality.

[0012] 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.

[0013] Please see Figure 1-4This utility model provides a technical solution: a multifunctional concrete mold size measuring tool, including a column 1. A handle 10 is fixedly connected to the top of the column 1, allowing workers to easily grip the measuring tool and ensuring stability during the measurement process. The column 1 is located inside the mold. Multiple fixed cylinders 2 are fixedly connected to the side of the column 1. There are four fixed cylinders 2, symmetrically distributed around the center of the column 1. Sliding rods 3 are slidably connected inside each fixed cylinder. A measuring assembly is located inside the column 1 to simultaneously push the multiple sliding rods 3 out of the fixed cylinders 2. Through the measuring assembly, the ends of the multiple sliding rods 3 are pushed to the inner wall of the mold, thereby accurately obtaining the internal dimensions of the mold.

[0014] The measuring assembly includes an electric push rod 4 located inside the column 1. The bottom end of the electric push rod 4 is fixedly connected to a plate 5, and the other end is fixedly connected to the inner wall of the column 1. A vertical rod 6 is fixedly connected to the bottom of the plate 5, and a second plate 7 is fixedly connected to the outer wall of the vertical rod 6. Both plates 5 and 7 can slide freely inside the column 1. The cavity from plate 7 to the end of the slide rod 3 is filled with liquid and maintained under negative pressure. The electric push rod 4 can drive plate 7 downwards via the vertical rod 6, thereby using the pressure of the liquid to push the push rod to slide within the fixed cylinder 2. It is worth noting that because the slide rod 3 is pushed by pressurizing the liquid, the end of the slide rod 3 will only stop when it reaches the mold surface. This allows the tool to be used for trial mold measurements of different side lengths, improving its applicability.

[0015] Furthermore, a fixed plate 8 is provided inside the column 1 and slidably connected thereto. The outer wall of the fixed plate 8 is fixedly connected to the inner wall of the column 1. An air cavity is formed between the fixed plate 8 and the plate body 5. The air in this air cavity is automatically filled by an air valve. The end of the slide rod 3 has a chamber, which is connected to the air cavity between the fixed plate 8 and the plate body 5 through an air pipe. During the descent of the plate body 5, the plate body 5 will push out the air above the fixed plate 8, which will then enter the chamber at the end of the push rod through the air pipe and be discharged outwards. The discharged gas can blow the mold surface to be contacted, achieving the effect of cleaning the mold surface residue and making the measurement data more accurate.

[0016] The ends of the slide rods 3 are pointed. After both slide rods 3 reach the inner wall of the mold surface, the operator can remove the measuring tool and directly measure the distance between the ends of the two slide rods 3 to obtain the internal standard dimensions of the test mold. The pointed ends of the slide rods 3 can effectively handle mold surface testing with different shapes, improving the applicability of this tool. The bottom of the slide rods 3 is equipped with a support column 9 and is fixedly connected to it. The support column 9 will move synchronously with the slide rods 3 during movement, thereby increasing the support of the overall measuring tool and ensuring the verticality and accuracy of the measurement process.

[0017] Working principle: In use, the operator inserts the measuring tool into the mold using handle 10. The electric push rod 4 is then activated, causing plate 5 to move downwards. Plate 5, via the vertical rod 6, causes plate 7 to slide downwards simultaneously. Because the cavity between plate 7 and the end of the slide rod 3 is filled with liquid and maintained under negative pressure, the pressure of the liquid as plate 7 moves downwards pushes the slide rod 3 outwards within the fixed cylinder 2 until the end of the slide rod 3 reaches the inner wall of the mold.

[0018] As plate 5 moves downward, the air in the air cavity between fixed plate 8 and plate 5 is pushed out by plate 5, enters the chamber at the end of slide rod 3 through the air pipe, and then exits from the end of slide rod 3. The discharged gas blows the mold surface to be contacted, cleaning away residual concrete particles and other debris on the mold surface to ensure the accuracy of the measurement reference surface.

[0019] Once both opposing sliding rods 3 have reached the inner wall of the mold surface, the operator removes the measuring tool from the mold and directly measures the distance between the ends of the two sliding rods 3 to obtain the internal standard dimensions of the mold. The support column 9 at the bottom of the sliding rod 3 moves synchronously during the movement of the sliding rod 3, increasing the support of the overall measuring tool, ensuring the verticality and accuracy of the tool during measurement, and avoiding measurement errors caused by tool tilting.

[0020] Compared with existing technologies, this invention effectively solves the problems of narrow operating space, inability of measuring claws to effectively extend and position, susceptibility to interference from residual concrete particles, and human error that can be introduced by visual readings when using ordinary vernier calipers or depth gauges to measure the dimensions of concrete test molds. It improves the accuracy and efficiency of measurement and has wide applicability, and can be used for measuring test molds with different side lengths and shapes.
