Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0022] like Figures 1 to 4 As shown, this utility model provides a portable rebar spacing measuring device, including a first measuring plate 1 and two sets of second measuring plates 2. The two sets of second measuring plates 2 are arranged opposite each other on both sides of the first measuring plate 1, and two sets of first connecting members 101 are correspondingly arranged on both sides of the first measuring plate 1. Each set of second measuring plates 2 has a second connecting member 102 on the side closest to the first measuring plate 1. The two sets of second measuring plates 2 are foldably connected to the two sets of first connecting members 101 of the first measuring plate 1 via the second connecting members 102. Measuring grooves 103 are correspondingly formed at the top of the first measuring plate 1 and the top of the measuring grooves 103. Limiting rails 104 are also provided at the top of the limiting rails 104 and the measuring grooves 103. Multiple sets of measuring pointers 3 are provided on the limiting rails 104, and the multiple sets of measuring pointers 3 can be slidably locked within the limiting rails 104. The first measuring plate 1 and the two sets of second measuring plates 2 form a foldable connection structure through the first connecting members 101 and the second connecting members 102. When the device is idle or in transport, the two sets of second measuring plates 2 can be folded together along the connecting parts towards the first measuring plate 1, reducing the overall size and allowing for easy one-handed handling or placement in a tool bag. In actual measurement scenarios, the second measuring plates 2 can be unfolded to form a laterally extended measuring surface with the first measuring plate 1, adapting to different densities of rebar arrangement and increasing the applicability of the device during measurement.

[0023] Meanwhile, the flip-out connection formed by the first connector 101 and the second connector 102 allows the second measuring plate 2 to have multiple degrees of freedom of rotation. In narrow construction spaces or areas with complex intersecting reinforcements, the second measuring plate 2 can rotate flexibly around the connection point to adjust to a state parallel or perpendicular to the reinforcement to be measured, thereby maintaining effective measurement of the target reinforcement.

[0024] The distance measuring groove 103 is longitudinally opened along the top of the first distance measuring plate 1 and the second distance measuring plate 2, providing a precise guide track for the distance measuring pointer 3. The bottom of the distance measuring pointer 3 is embedded in the groove, and during the sliding process, it is constrained by the groove wall and can only move horizontally along the direction of the rebar spacing, avoiding measurement errors caused by tilting or offset. The limiting rail 104 spans across the distance measuring groove 103, forming a closed track together with the groove wall, preventing the distance measuring pointer 3 from jumping upward or leaving the track during measurement; at the same time, multiple sets of distance measuring pointers 3 can slide within the limiting rail 104, and the positions of multiple rebars can be located simultaneously during measurement, directly obtaining the spacing between adjacent rebars without the need for multiple measurements and calculations, thus improving measurement efficiency.

[0025] like Figures 1 to 4 As shown, corresponding fixing holes are provided at the connection points of the two sets of first connecting members 101 and the two sets of second connecting members 102, and a limiting bolt 201 is inserted into each of the two sets of fixing holes. The combination of fixing holes and limiting bolts 201 fixes the connection between the first connecting member 101 and the second connecting member 102. When the first measuring plate 1 and the second measuring plate 2 are unfolded to the measuring angle, the limiting bolt 201 is inserted into the corresponding fixing hole to restrict the rotation of the second measuring plate 2 around the connection point, so that the measuring device forms a stable and rigid structure. During the measurement process, if the device is subjected to external force collision or movement, the second measuring plate 2 will not be displaced, ensuring stable and reliable measurement data. At the same time, by tightening or loosening the limiting bolt 201, the friction between the first connecting member 101 and the second connecting member 102 can be changed. When the limiting bolt 201 is in a semi-tightened state, the second measuring plate 2 will be subject to controllable resistance during the flipping process, which allows for manual adjustment of the angle and can maintain stability in any position. When measuring inclined reinforcing bars, the second measuring plate 2 can be adjusted to an angle parallel to the reinforcing bar and fixed, and the measuring posture can be maintained without additional support.

[0026] like Figures 2 to 3 As shown, two sets of second ranging plates 2 have two sets of limiting slots 301 facing each other. When the two sets of second ranging plates 2 are parallel and in contact, limiting slots 301 form limiting holes, and limiting knobs 302 are inserted into the limiting holes. When the two sets of second ranging plates 2 are folded and in parallel contact, the limiting slots 301 on both sides align to form limiting holes. After inserting the limiting knobs 302, the two sets of second ranging plates 2 are firmly fixed together. During the carrying or transportation of the device, the second ranging plates 2 will not unfold on their own due to shaking or collision, maintaining a compact shape, making it convenient for construction personnel to store in tool bags or hang on their waists; when storing, simply fold the second ranging plates 2 and align them so that the limiting slots 301 correspond to form holes, and insert the limiting knobs 302 to complete the fixation. Compared with complex buckle or screw structures, this method requires no additional tools, can be operated with one hand, shortens the device storage time, and improves ease of use.

[0027] like Figures 1 to 4As shown, multiple sets of distance measuring scales 401 are evenly arranged within the distance measuring groove 103, and the distance measuring pointer 3 is in contact with the distance measuring scales 401. The distance measuring scales 401 within the distance measuring groove 103 provide a quantitative standard for measuring rebar spacing. Each scale corresponds to a fixed length value. Multiple sets of distance measuring pointers 3, in conjunction with the distance measuring scales 401, can simultaneously measure multiple sets of rebar spacing. By placing multiple pointers against different rebars respectively, the difference in scale values ​​between adjacent pointers can be directly read, allowing multiple sets of data to be obtained in a single operation, thus shortening the measurement time.

[0028] like Figures 1 to 3 As shown, the top of the distance measuring pointer 3 is also provided with an assembly hole, through which a limiting pin 501 passes, and the limiting pin 501 contacts the limiting rail 104; an extension rod 601 is also provided on one side of the distance measuring pointer 3, and a distance measuring rod 602 is folded inside the extension rod 601. The limiting pin 501 passes through the assembly hole at the top of the distance measuring pointer 3, and forms a limiting structure after contacting the limiting rail 104. During measurement, the distance measuring pointer 3 is pushed along the limiting rail 104 to the edge of the reinforcing bar, and the limiting pin 501 is inserted to fix the pointer position, preventing it from shifting when reading the distance measuring scale 401, ensuring the accuracy of the measurement data; removing the limiting pin 501 allows the distance measuring pointer 3 to slide again, facilitating the adjustment of the measurement position.

[0029] The extension rod 601 on one side of the distance measuring pointer 3 is combined with the foldable distance measuring rod 602. When the conventional measurement range is insufficient, the distance measuring rod 602 can be extended to extend the measurement length. When measuring large-spacing steel bars or needing to cross obstacles, extending the distance measuring rod 602 allows the pointer to reach the target position without changing the measuring tool, thus expanding the applicable scenarios of the device. At the same time, the limiting pin 501, extension rod 601, and distance measuring rod 602 are detachable, and any damaged component can be replaced individually. If the limiting pin 501 is worn, it can be directly pulled out and replaced with a new one; if the distance measuring rod 602 is damaged, it can be disassembled and replaced in the folded state, without the need for an overall maintenance device, reducing maintenance and time costs.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the top of the first distance measuring plate 1 is also provided with two sets of mounting parts, and the mounting parts are rotatably equipped with handles 701. The two sets of mounting parts at the top of the first distance measuring plate 1 are equipped with rotatable handles 701. When carrying, the handles 701 can be folded against the plate surface to reduce the overall size of the device, making it easy to put into a tool bag or hang on the waist; when measuring, the handles 701 are rotated out, and the construction personnel can hold the device stably with one hand. In high-altitude operations or narrow spaces, the angle and position of the device can be adjusted by the handles 701 to accurately measure the spacing of the rebars, avoiding measurement errors caused by unstable hand grip. In addition, the force point provided by the handles 701 makes long-term measurement operations less tiring and improves work efficiency.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
