[0003] However, during the construction process, the length of the steel bars cannot meet the construction needs at one time, so the steel bars need to be continuously extended during the pouring process. During the extension, the construction workers need to connect the steel bars. During the connection process, due to the heavy weight of the steel bars, manual docking and positioning by the workers alone requires a lot of manpower. At the same time, there are problems such as displacement of the steel bars and falling from the workbench due to the inability of the workers to sustain their strength during the docking process, which greatly increases the risk of construction and reduces construction efficiency. Summary of the invention

[0036] like Figures 1 to 6 As shown, a steel bar positioning device of this embodiment includes a fixing frame 1, an extension mechanism 2, an adjustment mechanism 3 and a positioning mechanism 4, wherein:

[0037] The fixed frame 1 includes two L-shaped horizontal frames 11, a vertical frame 12 is connected between the two L-shaped horizontal frames 11, a storage groove 13 is provided in the L-shaped horizontal frame 11, and the four fixed frames 1 are connected to form a rectangular frame through an extension mechanism 2; a limiting groove 14 is provided on the vertical frame 12, and a sliding groove 15 is provided on the side wall of the L-shaped horizontal frame 11.

[0038] The extension mechanism 2 includes an extension plate 21, which is movably mounted in the receiving slot 13; sliding blocks 22 are respectively provided at both ends of the extension plate 21, and a plurality of elastic pins 23 are provided in the middle of the extension plate 21, the sliding blocks 22 are movably mounted in the slide slot 15, and the elastic pins 23 are retractably mounted in the receiving slot 13. Six elastic pins 23 are provided on each extension plate 21.

[0039] The adjustment mechanism 3 includes a threaded rod 31, which is arranged on the inner side of the vertical frame 12. A moving block 32 is threadedly mounted on the threaded rod 31. A first protrusion 33 is arranged at the other end of the moving block 32. A connecting hole 34 is arranged on the first protrusion 33. Limiting blocks 35 are arranged on both sides of the moving block 32. The limiting blocks 35 are movably mounted in the limiting groove 14. Rotating handles 36 are arranged at both ends of the threaded rod 31. Two moving blocks 32 are mounted on each threaded rod 31, and the internal threads of the two moving blocks 32 are in opposite directions.

[0040] The positioning mechanism 4 includes a U-shaped connector 41, which is movably mounted in the connecting hole 34. The open end of the U-shaped connector 41 is connected to the positioning frame 42. The two side walls of the positioning frame 42 are respectively provided with sliding holes 43. The sliding holes 43 are respectively equipped with sliding rods 44. The two sliding rods 44 are respectively provided with positioning members 45 at one end located in the positioning frame 42. The two ends of the positioning members 45 are respectively provided with guide members 46. The connection between the positioning frame 42 and the U-shaped connector 41 is provided with a second protrusion 47. The first protrusion 33 is provided with a convex curved surface, and the second protrusion 47 is provided with a concave curved surface. The convex curved surface and the concave curved surface are respectively provided with meshing teeth. The first protrusion 33 and the second protrusion 47 are meshed and assembled through the meshing teeth. A spring 48 is sleeved on the sliding rod 44. One end of the spring 48 is connected to the outer wall of the positioning member 45, and the other end is connected to the inner wall of the positioning frame 42. The positioning member 45 and the guide member 46 are both arc-shaped plates, and the guide member 46 is connected to the positioning member 45 in an outwardly inclined manner.

[0041] The steel bar positioning device of the utility model is provided with four fixing frames 1, and the four fixing frames 1 are connected to each other through eight extension plates 21 to form a rectangular parallelepiped frame. When in use, the staff places one end of the steel bar between the two positioning members 45. During the placement process, one end of the steel bar first contacts the side wall of the arc-shaped guide member 46. As the steel bar is placed, one end of the steel bar will slide along the side wall of the guide member 46, thereby entering between the two positioning members 45, so that the two positioning members 45 clamp and fix the steel bar under the action of the elastic force of the two springs 48, thereby facilitating the staff to perform subsequent processing of the steel bar. The device can also be adjusted as needed:

[0042] Angle adjustment: Apply external force to the U-shaped connector 41 according to the position of the steel bar. Under the action of the external force, the meshing teeth of the first protrusion 33 and the second protrusion 47 are disengaged, so that the staff can adjust the angle between the U-shaped connector 41 and the moving block 32. After the adjustment is completed, the U-shaped connector 41 is not affected by the external force, so that the meshing teeth of the first protrusion 33 and the second protrusion 47 are re-engaged, thereby fixing the moving block 32 and the U-shaped connector 41 to avoid changes in the angle between the moving block 32 and the U-shaped connector 41 during use. After the adjustment is completed,

[0043] Distance adjustment: Since the threads on the two moving blocks 32 are opposite, when the threaded rod 31 rotates, the moving directions of the two moving blocks 32 are opposite. Therefore, the threaded rod 31 can be rotated by rotating the handle 36 to adjust the position and distance of the two moving blocks 32 on the same threaded rod 31. When the staff rotates the threaded rod 31 to drive the two moving blocks 32 to move, the limiting groove 14 and the limiting block 35 cooperate to limit the horizontal angle of the two moving blocks 32, so that the two moving blocks 32 are always perpendicular to the fixed frame 11, thereby avoiding the blocking between the moving block 32 and the fixed frame 1 during the movement.

[0044] Extension adjustment: When the device needs to be extended, the four fixing frames 1 are pulled outward. During the pulling process, the fixing frames 1 move toward the two ends of the extension plate 21, and the inner side walls of the receiving slots 13 of the fixing frames 1 gradually release the limit on the elastic pins 23. As the elastic pins 23 move to the outside of the fixing frames 1, the inner side walls of the receiving slots 13 cannot lock the elastic pins 23, so that the elastic pins 23 pop out under the action of their own elastic force, limiting the position of the extension plate 21 and preventing the extension plate 21 from retracting into the receiving slots 13 during use. When the fixing frames 1 are extended, the four sliding blocks 22 are respectively located inside the slide slots 15 and slide, thereby preventing the extension plate 21 from detaching from the fixing frames 1 when the fixing frames 1 are extended.

[0045] It should be noted that the embodiments described herein are only partial embodiments of the present invention, rather than all implementations of the present invention, and the embodiments are only exemplary, and their role is only to provide a more intuitive and clear way to understand the content of the present invention, rather than to limit the technical solutions described in the present invention. Without departing from the concept of the present invention, all other implementation methods that ordinary technicians in the field can think of without creative work, and other simple replacements and various changes to the technical solutions of the present invention, all belong to the protection scope of the present invention.
