[0035] In the embodiments of the present utility model, please refer to 6 and Figure 7The auxiliary structure 4 includes a baffle 41, the diameter of which matches the diameter of the circular hole 301, the baffle 41 fits the inner wall of the circular hole 301, the arc surface of the baffle 41 is fixedly connected with two ear plates 42, the side of the ear plate 42 is provided with a screw hole 43, the upper end of the anchor rod 5 is fixedly connected with two fixing seats 44, the side of the fixing seat 44 is threaded with a screw 45, the screw 45 is adapted to the size of the screw hole 43, by setting the auxiliary structure 4, after the anchor rod 5 is docked with the anchor pipe 1, the personnel can easily adjust the baffle 41 to seal the circular hole 301, and then the parts in the circular hole 301 can be sealed and protected. , effectively improving the service life of the internal parts of the circular hole 301, one end of the screw 45 is fixedly connected with a guide block 46, and the guide block 46 has a conical structure. Since the guide block 46 fixed at one end of the screw 45 is small in size, the screw 45 can be easily inserted into the screw hole 43, and the arc surface of the baffle 41 is fixedly connected with a sealing ring 47, the lower surface of the sealing ring 47 is in contact with the upper end of the anchor rod 5, and the sealing ring 47 can block the small gap between the baffle 41 and the anchor rod 5, thereby improving the sealing effect of the connection between the anchor rod 5 and the baffle 41, thereby further improving the sealing effect of the baffle 41 on the circular hole 301.

[0036] The working principle of a detachable anchor bolt structure provided by the utility model is as follows: when the anchor bolt is needed, the anchor pipe 1 is first installed to the specified position, and the anchor pipe 1 is poured into the concrete layer. When the anchor rod 5 needs to be installed, the anchor rod 5 is first placed inside the anchor pipe 1, and then the screw rod 302 is rotated with the help of the anti-slip groove 311. The screw rod 302 drives the adjusting ring 303 to move downward. During the process of the screw rod 302 driving the adjusting ring 303 to move, the positioning plate 307 fixed on the positioning ring will move along the arc surface of the positioning rod 308, so that the adjusting ring 303 has a rotational offset during the movement process. The adjusting ring 303 drives the pressing block 304, and the pressing block 304 squeezes the plug block 305 until the plug block 305 is squeezed into the insertion hole 306, and the rotation of the screw rod 302 can be stopped. At this time, the installation of the anchor rod 5 is completed. When the anchor rod 5 needs to be removed, the screw rod 302 is rotated in the opposite direction with the help of the anti-slip groove 311, so that the screw rod 302 drives the adjusting ring 303 to move upward. When the adjusting ring 303 drives the pressure block 304 to separate from the plug block 305, the spring 310 can pull the plug block 305 to quickly move away from the socket 306 until the plug block 305 is separated from the socket 306, thereby achieving the effect of being able to quickly remove the anchor rod 5. When the plug block 305 is separated from the socket 306, the anchor rod 5 can be taken out of the anchor rod 5, thereby completing the removal of the anchor rod 5. By setting the adjustment structure 3, the fixing effect between the anchor rod 5 and the anchor pipe 1 is improved, thereby improving the pull-out resistance of the anchor bolt, and personnel can easily remove the anchor rod 5, thereby improving the practicality of the anchor bolt structure.

[0037] When it is necessary to adjust the baffle 41 to seal the circular hole 301, the baffle 41 is first moved to drive the ear plate 42, and the ear plate 42 is placed on the inner wall of the fixing seat 44. After the screw 45 is aligned with the screw hole 43 on the side of the ear plate 42, the screw 45 is rotated to insert into the screw hole 43, and the baffle 41 can be installed. Since the guide block 46 fixed at one end of the screw 45 is small in size, the screw 45 can be easily inserted into the screw hole 43. The sealing ring 47 can block the small gap between the baffle 41 and the anchor rod 5, thereby improving the sealing effect of the connection between the anchor rod 5 and the baffle 41, thereby further improving the sealing effect of the baffle 41 on the circular hole 301. By setting the auxiliary structure 4, after the anchor rod 5 is docked with the anchor pipe 1, the personnel can easily adjust the baffle 41 to seal the circular hole 301, and then the parts in the circular hole 301 can be sealed and protected, effectively improving the service life of the parts inside the circular hole 301.
