[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a flange joint inside a recycled concrete pole, comprising a No. 1 flange 1, a No. 2 flange 3, a No. 1 connecting pipe 2 and a No. 2 connecting pipe 4. The side wall of the No. 1 connecting pipe 2 is rotatably mounted with the No. 1 flange 1, the side wall of the No. 2 flange 3 is fixed with the No. 2 connecting pipe 4, the No. 1 flange 1 is provided with a positioning mechanism 5 for conveniently limiting the No. 1 flange 1 and the No. 2 flange 3, and the No. 1 connecting pipe 2 is provided with an adjusting mechanism 6 for rotating the No. 1 flange 1.

[0024] Specifically, the positioning mechanism 5 includes a slide groove 501, a slider 502, a hinge rod 503, a transmission ring 504, a return spring 505 and a positioning block 506; the slide groove 501 is arranged on the side of the No. 1 flange 1 close to the No. 1 connecting pipe 2, and the slide groove 501 is slidably mounted with a slider 502 on the inner wall, the slider 502 is hinged with a hinge rod 503, the end of the hinge rod 503 away from the slider 502 is hinged with a transmission ring 504, and the slider 502 is fixed with a positioning block 506 on the side away from the No. 1 connecting pipe 2, and the slider 502 and the positioning block 506 are provided in two groups, and the two groups of sliding The block 502 and the positioning block 506 are symmetrically arranged with the center line of the first flange 1 in the vertical direction as the symmetry axis. The side of the positioning block 506 close to the first flange 1 is an arc-shaped surface, and the center point of the two groups of positioning blocks 506 is the same center point as the center point of the first flange 1 and the second flange 3. A reset spring 505 is fixed on the side of the slider 502 away from the positioning block 506. The side of the reset spring 505 away from the slider 502 is fixed to the inner wall of the slide groove 501. By setting the reset spring 505, the slider 502 can be reset, and then when it is necessary to reset When the No. 1 flange 1 and the No. 2 flange 3 are connected, the transmission ring 504 is pushed to approach the No. 1 flange 1, which will cause the transmission ring 504 to squeeze the hinge rod 503, so that the hinge rod squeezes 503 to press the two sets of sliders 502 away from each other, driving the two sets of positioning blocks 506 away from each other, so that the No. 1 flange 1 and the No. 2 flange 3 can be aligned. By loosening the transmission ring 504, the slider 502 can be reset because the reset spring 505 is in a stretched state, so that the two sets of positioning blocks 506 are close to each other, and the positioning blocks 506 can be aligned with the No. 1 flange 1 and the No. 2 flange 3. The outer wall of the flange 3 fits together, which has the effect of positioning the No. 1 flange 1 and the No. 2 flange 3, preventing the No. 1 flange 1 and the No. 2 flange 3 from being displaced when installing bolts in the bolt holes of the flange 1 and the No. 2 flange 3, making it inconvenient to insert the bolts into the bolt holes; and when the No. 2 flange 3 needs to be removed from the No. 1 flange 1, the transmission ring 504 is pushed, and the two sets of positioning blocks 506 are moved away from each other through the hinge rod 503 and the slider 502, so that the positioning of the No. 2 flange 3 can be released and the No. 2 flange 3 can be removed.

[0025] Specifically, the adjustment mechanism 6 includes a threaded groove 601, a threaded sleeve 602, a sleeve 603 and a sleeve rod 604. The outer wall of the No. 1 connecting pipe 2 is provided with a threaded groove 601, and the outer wall of the threaded groove 601 is threadedly connected with a threaded sleeve 602. The sleeve 603 is fixed to the side of the threaded sleeve 602 close to the No. 1 flange 1. The sleeve rod 604 is slidably installed on the inner wall of the sleeve 603. The end of the sleeve rod 604 away from the threaded sleeve 602 is fixed to the transmission ring 504. When the transmission ring 504 is pushed to move, the sleeve rod 604 can be moved out of the sleeve 603. When it is necessary to adjust the positioned No. 1 flange 1 When installing flange No. 1 and flange No. 2 3, it is necessary to align the bolt holes on flange No. 1 and flange No. 3. By rotating the threaded sleeve 602 forward, the sleeve 603 can be driven to rotate, so that the sleeve rod 604 can be rotated, and then the positioning mechanism 5 can be driven to rotate, so that flange No. 1 can be rotated. When the bolt hole on flange No. 1 is rotated to be aligned with the bolt hole on flange No. 2 3, the rotation of the threaded sleeve 602 can be stopped. Since the threads have a self-locking function, flange No. 1 can be fixed, making it convenient for the staff to perform connection operations.

[0026] Working principle: When in use, pushing the transmission ring 504 toward the No. 1 flange 1 will cause the transmission ring 504 to squeeze the hinge rod 503, so that the hinge rod squeezes 503 to press the two sets of sliders 502 away from each other, driving the two sets of positioning blocks 506 away from each other, and then the No. 1 flange 1 and the No. 2 flange 3 can be aligned. By loosening the transmission ring 504, the reset spring 505 is in a stretched state, so that the slider 502 can be reset, and the two sets of positioning blocks 506 can be close to each other, and then the positioning blocks 506 can be fit with the outer walls of the No. 1 flange 1 and the No. 2 flange 3, which has the effect of positioning the No. 1 flange 1 and the No. 2 flange 3, preventing the No. 1 flange 1 and the No. 2 flange 3 from being displaced when installing bolts in the bolt holes of the No. 1 flange 1 and the No. 2 flange 3, which will affect the connection effect between them.

[0027] By rotating the threaded sleeve 602 forward, the sleeve 603 can be driven to rotate, so that the sleeve rod 604 can be rotated, and then the positioning mechanism 5 can be driven to rotate, so that the No. 1 flange 1 can be rotated. When the bolt holes on the No. 1 flange 1 are rotated to align with the bolt holes on the No. 2 flange 3, it is convenient for the staff to perform the connection operation.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
