The clamping arm is gradually locked under the push of the extrusion block. When the clamping arm is completely locked, the steel bar can be clamped. Then, the steel bar on one side of the second frame is clamped according to the above steps, and the positioning operation of the steel bar can be completed. By providing the clamping assembly, the positioning structure can be installed from various positions of the steel bar, thereby reducing the problem that when the positioning structure uses a sleeve, it can only be installed from the end, and further improving the convenience of disassembling the positioning structure.

[0015] 2. In the present utility model, by providing a connecting assembly, when installing the first frame and the second frame, the pressing frame is held down. The pressing frame pushes the load-bearing plate, the load-bearing plate pulls the fastening block, and compresses the compression spring. The fastening block is pulled and slides into the assembly cavity, and the compression spring is deformed by extrusion. When the fastening block completely slides into the assembly cavity, the second frame is pushed. The second frame pushes the retaining pin to insert into the limiting cavity. Then, the pressing frame is released. The pressing frame loses the pressure applied to the load-bearing plate, the load-bearing plate loses the pressure on the compression spring, and the compression spring rebounds without pressure and pushes the load-bearing plate to reset. The load-bearing plate pushes the fastening block to insert into the limiting cavity and locks the position of the retaining pin. Then, with the cooperation of the retaining pin and the fastening block, the second frame can be installed on the first frame. By providing the connecting assembly, the frames of the positioning structure can be disassembled, thereby further improving the disassembly efficiency of the positioning structure.

[0024] Next, specifically describe the specific settings and functions of its clamping assembly 4 and connection assembly 5.

[0025] In this implementation: The clamping assembly 4 includes a limit shaft 41, the limit shaft 41 is rotatably connected to the inner wall of the installation cavity 3, a clamping arm 42 is fixedly connected to the surface of the limit shaft 41, a damping pad 43 is fixedly connected to the inner circumference of the clamping arm 42, bidirectional lead screws 44 are rotatably connected to the inner walls of the frame 1 and the frame 2 located in the installation cavity 3, an extrusion block 45 is threadedly connected to the surface of the bidirectional lead screw 44, positioning rings 46 are fixedly connected to both ends of the bidirectional lead screw 44, and knobs 47 are fixedly connected to both ends of the bidirectional lead screw 44.

[0026] Specifically, the number of clamping arms 42 is two. The two clamping arms 42 are symmetrically arranged up and down with respect to the limit shaft 41. The clamping arms 42 are arc-shaped. The clamping arms 42 can be stably clamped on the surface of the steel bar under the extrusion of the extrusion block 45, so as to lock the positions of the first frame 1 and the second frame 2.

[0027] Specifically, the extrusion block 45 is slidably connected to the inner wall of the installation cavity 3. The extrusion block 45 penetrates the surface of the first frame 1. The number of extrusion blocks 45 is two. The two extrusion blocks 45 are symmetrically arranged left and right with respect to the bidirectional lead screw 44.

[0028] In this embodiment: The position of the clamping arm 42 can be locked by the extrusion block 45 under the action of the bidirectional lead screw 44 to ensure the clamping effect of the clamping arm 42.

[0029] Specifically, the positioning ring 46 is rotatably connected to the inner wall of the installation cavity 3. The arc surface of the knob 47 is provided with anti-slip lines. The bidirectional lead screw 44 can be operated by the staff through the knob 47, so that the bidirectional lead screw 44 can be rotated by the staff.

[0030] In this embodiment: The connecting component 5 includes a pin 51. The pin 51 is fixedly connected to the side surface of the second frame 2. An assembly cavity is formed on the surface of the pin 51. A load-bearing plate 52 is slidably connected to the inner wall of the assembly cavity of the pin 51. A compression spring 53 is fixedly connected to the surface of the load-bearing plate 52. The compression spring 53 is fixedly connected to the inner wall of the assembly cavity. A buckle 54 is fixedly connected to the surface of the load-bearing plate 52. A pressing frame 55 is fixedly connected to the side surface of the load-bearing plate 52. The pressing frame 55 penetrates the surface of the pin 51. A limiting cavity 56 is formed on the surface of the first frame 1. The pin 51 is inserted into the inner wall of the limiting cavity 56. The buckle 54 is inserted into the inner wall of the limiting cavity 56.

[0031] In this embodiment: The position of the load-bearing plate 52 can be restricted by the compression spring 53 to ensure the stability of the load-bearing plate 52 in the static state.

[0032] Specifically, the number of pins 51 is two. The two pins 51 are symmetrically arranged left and right with respect to the second frame 2. The side of the pin 51 close to the first frame 1 is chamfered. Through the cooperation of the pin 51 and the buckle 54, the first frame 1 and the second frame 2 can be installed together when the pin 51 is inserted into the limiting cavity 56.

[0033] Specifically, the side of the buckle 54 away from the load-bearing plate 52 is chamfered. The buckle 54 is slidably connected to the inner wall of the assembly cavity. The buckle 54 penetrates the surface of the pin 51.

[0034] In this embodiment: The position of the pin 51 located in the limiting cavity 56 can be restricted by the buckle 54 under the restriction of the load-bearing plate 52 and the limiting spring.

[0035] Working principle: When using the positioning structure to restrict the steel bar, ensure that the clamping arms 42 are in the unfolded state. Install the first frame 1 and the second frame 2 on the surface of the steel bar, and connect the first frame 1 and the second frame 2 with the aid of the connection device. When the first frame 1 and the second frame 2 are connected to each other, rotate the clamping arms 42. The clamping arms 42 push the damping pad 43 under the guidance of the limit shaft 41, and the damping pad 43 abuts against the surface of the steel bar. When the clamping arms 42 on both sides of the first frame 1 are in the closed state, rotate the knob 47 clockwise. The knob 47 rotates the bidirectional lead screw 44, and the bidirectional lead screw 44 meshes with the extrusion block 45. The extrusion block 45 moves in the direction of the clamping arms 42 under the action of the bidirectional lead screw 44 and pushes the clamping arms 42. The clamping arms 42 are gradually locked under the push of the extrusion block 45. When the clamping arms 42 are completely locked, the steel bar can be clamped. Then, clamp the steel bar on one side of the second frame 2 according to the above steps, and the positioning operation of the steel bar can be completed. By setting the clamping assembly 4, the positioning structure can be installed from various positions of the steel bar, thus reducing the problem that when the positioning structure uses a sleeve, it can only be installed from the end, and further improving the convenience of disassembling the positioning structure;

[0036] In addition, when installing the first frame 1 and the second frame 2, press and hold the pressing frame 55. The pressing frame 55 pushes the load-bearing plate 52. The load-bearing plate 52 pulls the buckle 54 and compresses the compression spring 53. The buckle 54 is pulled and slides into the assembly cavity, and the compression spring 53 is compressed and deformed. When the buckle 54 completely slides into the assembly cavity, push the second frame 2. The second frame 2 pushes the pin 51 into the limit cavity 56. Then release the pressing frame 55. The pressing frame 55 loses the pressure exerted on the load-bearing plate 52. The load-bearing plate 52 loses the pressure on the compression spring 53. The compression spring 53 rebounds without pressure and pushes the load-bearing plate 52 to reset. The load-bearing plate 52 pushes the buckle 54 into the limit cavity 56 and locks the position of the pin 51. Then, with the cooperation of the pin 51 and the buckle 54, the second frame 2 can be installed on the first frame 1. By setting the connection assembly 5, the frame of the positioning structure can be disassembled, thus further improving the disassembly efficiency of the positioning structure.
