[0024] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0027] Example The present invention provides a steel bar positioning tool suitable for different steel bar spacings, such as Figure 1-2 As shown, the structure includes a fixed rod 1, which is a columnar body with a horizontal axis under normal conditions. The fixed rod 1 includes a length limiting portion 11 and two position limiting portions 12. The position limiting portions 12 are respectively arranged at both ends of the length limiting portion 11, and the length limiting portion 11 and the two position limiting portions 12 are integrally formed; the position limiting portions 12 are distributed in the axial direction of the length limiting portion 11, and are respectively fixedly connected to one end of the length limiting portion 11.

[0028] As an embodiment, the length limiting portion 11 is in the shape of a circular columnar structure. It is understood that the shape is not limited, the length limiting portion 11 is a rectangular parallelepiped, and its cross-section can be rectangular, elliptical, etc.; the tubular length limiting portion 11 can facilitate the movement of the fixing rod 1, and facilitate the staff to move the tool faster; the rectangular length limiting portion 11 has better stability.

[0029] The limiting portion 12 is a columnar structure, and one end close to the length limiting portion 11 is fixedly connected to the length limiting portion 11; when subjected to a force that is always perpendicular to the axial direction of the limiting portion 12, the end of the limiting portion 12 away from the length limiting portion 11 is bent until it is perpendicular to the length limiting portion 11; when the force is removed, the limiting portion 12 does not recover and maintains the state after the force; when subjected to a force that causes the limiting portion 12 to return to its original position, the end of the limiting portion 12 away from the length limiting portion 11 is bent until the limiting portion 12 and the length limiting portion 11 are on the same axis; when the force is removed, the limiting portion 12 returns to a normal state.

[0030] It can be understood that in the present invention, the limiting portion 12 is arranged at both ends of the length limiting portion 11, and after being bent by force, it can be perpendicular to and fixed to the length limiting portion 11; when the limiting portion 12 is subjected to a force that causes the limiting portion 12 to return to its original position, the limiting portion 12 is bent by force, the force is cancelled, the limiting portion 12 and the length limiting portion 11 are on the same axis, and the limiting portion 12 returns to its original position.

[0031] like Figure 1-3 As shown, two positioning rods 2 are arranged on the fixed rod 1, and the two positioning rods 2 are located on the same side of the fixed rod 1, and the positioning rod 2 and the fixed rod 1 are perpendicular to each other; a sliding hole 21 is opened at one end of the positioning rod 2, and the sliding hole 21 is coaxially arranged with the length limiting portion 11 of the fixed rod 1, and the positioning rod 2 and the fixed rod 1 are slidingly connected through the sliding hole 21. When the positioning rod 2 slides, the two positioning rods 2 slide along the axial direction of the fixed rod 1.

[0032] It can be understood that in the present invention, the positioning rod 2 can slide on the fixing rod 1, wherein the positioning rod 2 and the steel bar are in contact with each other, and the relative distance between the two positioning rods 2 is observed by the sliding distance of the positioning rod 2 on the fixing rod 1, thereby limiting the distance between the two steel bars.

[0033] like Figure 1-3 As shown, one end of the positioning rod 2 close to the fixing rod 1 is threadedly connected with a positioning bolt 22, the positioning bolt 22 is coaxially arranged with the positioning rod 2, the end of the positioning bolt 22 abuts against the fixing rod 1, and the relative position of the positioning rod 2 and the fixing rod 1 is limited to remain unchanged; a scale line 3 is provided on the side of the fixing rod 1 away from the positioning rod 2, and the starting position of the scale line 3 is the middle of the length limiting portion 11.

[0034] As an embodiment, an inner scale 4 is provided on one side of the fixing rod 1 close to the positioning rod 2 , and the starting position of the inner scale 4 is the middle of the length limiting portion 11 .

[0035] It can be understood that, in the present invention, the positioning rod 2 slides to the specified position, the side of the two positioning rods 2 that are away from each other abuts against the steel bar, the positioning bolt 22 is screwed so that the end of the positioning bolt 22 abuts against the fixing rod 1, and the relative position of the positioning rod 2 and the fixing rod 1 is limited to not change, and then the length is observed through the scale line 3, and the scale line 3 is observed from the middle of the limiting portion 12 toward the two ends of the fixing rod 1, which is the distance between the two positioning rods 2; when the side of the two positioning rods 2 that are close to each other abuts against the steel bar respectively, the positioning bolt 22 is screwed so that the end of the positioning bolt 22 abuts against the fixing rod 1, and the relative position of the positioning rod 2 and the fixing rod 1 is limited to not change, and then the length is observed through the internal scale 4, which is the distance between the two positioning rods 2; the limitation method is the distance measurement between the positioning rods 2 and the distance measurement outside the positioning rods 2, and the force mode is different.

[0036] like Figure 1-4 As shown, a locking device 5 is provided at one end of the positioning rod 2 close to the fixed rod 1, and the locking device 5 includes two locking rods 51 and a stop component 6. The axis of the locking rod 51 is horizontally arranged, and the ends of the two locking rods 51 are rotatably connected to different positioning rods 2 respectively, and the other ends of the two locking rods 51 are close to each other and the two locking rods 51 are rotatably connected; the stop component 6 includes a stop threaded rod 61, and the axis direction of the stop threaded rod 61 is parallel to the positioning rod 2. A stop block 62 is provided at the position of the fixed rod 1 corresponding to the stop threaded rod 61, and the stop block 62 is fixed to the fixed rod 1, and the stop block 62 is threadedly connected to the stop threaded rod 61; a locking plate 63 is provided at the position of any locking rod 51 corresponding to the stop threaded rod 61, and the locking plate 63 is an arc-shaped plate-shaped structure. The locking plate 63 is fixed to one end of the locking plate 63 away from the fixed rod 1 and rotates synchronously with the locking rod 51, and the end of the stop threaded rod 61 close to the locking rod 51 abuts against the locking plate 63.

[0037] As an example, Figure 1-5 As shown, the stop component 6 includes a stop hook 64 and a stop column 66. The bent end of the stop hook 64 abuts against the fixed rod 1. A stop hole 65 is opened on the stop hook 64. The stop holes 65 are arranged in an array along the length direction of the stop hook. The stop column 66 is fixed to one end of any locking rod 51 away from the positioning rod 2. The stop column 66 is inserted into the stop hole 65 and is rotatably connected.

[0038] It can be understood that, in the present invention, the position of the locking rod 51 can be flexibly adjusted through the rotational connection design of the two locking rods 51. When the other ends of the two locking rods 51 are close to each other and rotationally connected, they can form a stable locking structure to firmly lock the positioning rod 2 in a position near the fixing rod 1. This design allows the positioning rod 2 to be firmly fixed as needed to prevent it from accidentally moving or loosening.

[0039] The design that the locking plate 63 rotates synchronously with the locking rod 51 enables the locking plate 63 to accurately adjust its position as the locking rod 51 rotates, thereby providing wider applicability.

[0040] Design of the stop threaded rod 61 and the stop block 62: By rotating the stop threaded rod 61, the contact force between the stop threaded rod 61 and the locking plate 63 can be adjusted, thereby achieving accurate locking of the position of the locking rod 51. This design not only increases the stability of the locking position, but also provides additional safety protection.

[0041] Design of the stop hook 64 and the stop post 66: As another embodiment, the bent end of the stop hook 64 abuts against the fixing rod 1 to ensure the stability of the stop hook 64; and the stop post 66 is inserted into the stop hole 65 and is rotatably connected, allowing the locking rod 51 to be fine-tuned within a certain range. This design ensures the firmness of the locking position and provides sufficient flexibility.

[0042] The implementation method of a steel bar positioning tool suitable for different steel bar spacings in the present application embodiment is as follows: The principle is: Strong adaptability: Through the limiting part 12 on the fixing rod 1, the tool can flexibly adapt to steel bars with different spacings. The limiting part 12 can be bent when subjected to a force perpendicular to the axial direction, and remain bent after the force is removed, which enables the tool to fit closely to steel bars with different spacings. By sliding the positioning rod 2, the positioning rod 2 and the limiting part 12 and the positioning rod 2 abut against each other, and the relative position of the steel bars is limited to not change, thereby providing a stable positioning effect.

[0043] High precision: The positioning rod 2 and scale line 3 (or inner scale 4) set on the tool allow workers to accurately measure and locate the spacing between the steel bars. By sliding the positioning rod 2 and observing the scale line 3, the distance between the two steel bars can be quickly and accurately determined, thus meeting the precision requirements in construction.

[0044] Easy operation: The sliding connection between the positioning rod 2 and the fixing rod 1 and the design of the positioning bolt 22 allow the staff to easily adjust the position of the positioning rod 2 and lock it in the desired position. In addition, the introduction of the locking device 5 (including the locking rod 51, the stop member 6, etc.) further simplifies the operation process and improves work efficiency.

[0045] Good stability: Whether through the threaded connection between the stop threaded rod 61 and the stop block 62, or through the rotational connection between the stop hook 64 and the stop column 66, the locking device 5 can provide a stable locking effect. This ensures that the positioning rod 2 will not accidentally move or loosen due to external forces after being locked in position, thereby ensuring the stability and safety of the construction.

[0046] Versatility: The tool provided by the present invention is not only suitable for measuring and locating the spacing between steel bars, but can also adapt to different construction requirements by adjusting the position of the positioning rod 2 and the state of the locking device 5. For example, the position of the positioning rod 2 can be fixed by screwing the positioning bolt 22, or the locking rod 51 and the stop member 6 can be adjusted to adapt to steel bars of different sizes.

[0047] Easy to carry and store: The design of the tool makes it easy to carry and store. Parts such as the fixing rod 1 and the positioning rod 2 can be assembled together compactly for easy transportation and storage. In addition, due to the selection of materials and the design of the structure, the tool also has high durability and corrosion resistance, and can maintain its performance for a long time.

[0048] In summary, the steel bar positioning tool suitable for different steel bar spacings provided by the present invention has the advantages of strong adaptability, high versatility, high precision, simple operation, good stability, versatility, and easy carrying and storage.
