The bottom end of the outer surface of the fixed slide rod 21 is movably connected to a locking device 27. A clamping guide block 26 is fixedly connected to the bottom surface of the slide plate 23.
[0026] In this embodiment, the anti-theft mechanism 2 is fixed to the bottom surface of the top cover 11 through the fixed slide rod 21. When the whole device is placed on the top of the manhole, the locking device 27 can be rotated to fit the bottom end of the outer surface of the fixed slide rod 21. At this time, the locking device 27 clamps the whole device at the edge of the manhole. At this time, a magnet with the same magnetism as the magnet 25 is placed on the top surface of the top cover 11. Under the condition of magnetic repulsion of the magnets, the magnet 25 drives the slide plate 23 at its bottom to move downward. Under the guiding action of the clamping guide block 26, the locking device 27 is clamped to prevent the locking device 27 from continuing to rotate, playing an anti-theft role.
[0027] Embodiment 2
[0028] As Figures 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the locking device 27 includes a fitting groove 272, the fitting groove 272 is closely attached to the bottom end of the outer surface of the fixed sliding rod 21, the side surface of the outer surface of the fitting groove 272 is fixedly connected with a locking block 271, a guiding arc surface 273 is arranged on the side surface of the locking block 271, the clamping guide block 26 is slidably connected to the side surface of the locking block 271, the other side surface of the locking block 271 is fixedly connected with a fixed block 274, the top surface of the fixed block 274 is fixedly connected with a rotating rod 275, and the top surface of the rotating rod 275 is fixedly connected with a top rotating block 276.
[0029] In this embodiment, by rotating the top rotating block 276 inside the hole on the top surface of the top cover 11 and not falling due to the presence of the anti - detachment block 15, inserting and rotating a card on the top surface of the top rotating block 276 can drive the fixed block 274 and the components on its side to rotate. When the fitting groove 272 rotates to a position where it is closely attached to the bottom end of the outer surface of the locking device 27, the movement will stop, and the whole device is clamped to the edge of the manhole, and is fixed at the current position through the clamping of the clamping guide block 26.
[0030] Embodiment 3
[0031] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the main body mechanism 1 includes a top cover 11, an anti - sway groove 12 is opened on the bottom surface of the top cover 11, a reinforcing rib 14 is fixedly connected inside the top cover 11, a telescopic lifting rod device 13 is fixedly connected inside the top surface of the top cover 11, a hole is opened inside the top surface of the top cover 11, an anti - detachment block 15 is fixedly connected to the bottom surface of the hole of the top cover 11, the rotating rod 275 is rotatably connected inside the anti - detachment block 15, the fixed sliding rod 21 is fixedly connected to the middle of the bottom surface of the top cover 11, the telescopic lifting rod device 13 includes a mounting block 131, the mounting block 131 is fixedly connected inside the top surface of the top cover 11, a sliding groove 132 is opened on the side surface of the mounting block 131, a slider 133 is slidably connected inside the sliding groove 132, a lifting rod 134 is fixedly connected to the side surface of the slider 133, and a water drainage port 135 is opened on the side surface of the lifting rod 134.
[0032] In this embodiment, the whole device is integrated through the top cover 11, the reinforcing rib 14 strengthens the bearing capacity of the top cover 11, the anti - sway groove 12 enables the top cover 11 to be clamped to the clamping block arranged on the manhole when installed, preventing the top cover 11 from rotating, the anti - detachment block 15 enables the top rotating block 276 to rotate without falling. The whole device with the released clamping can be lifted by holding the water drainage port 135 opened on the side surface of the lifting rod 134. During normal use, the water drainage port 135 can timely drain the accumulated water into the manhole, keeping the top cover 11 dry and increasing its service life.
[0033] Next, the working principle of this anti - theft manhole cover will be specifically described.
[0034] As Figures 1-5 shown, by placing the top cover 11 on the top surface of the manhole, inserting a card into the top surface of the top rotating block 276 and rotating it, the fixed block 274 and the components on its side can be driven to rotate. When the fitting groove 272 rotates to a position close to the bottom end of the outer surface of the locking device 27, the movement will stop, and the whole device is clamped on the edge of the manhole. At this time, a magnet with the same magnetism as the magnet 25 is placed on the top surface of the top cover 11. In the case of magnetic repulsion between the magnets, the magnet 25 drives the sliding plate 23 on its bottom surface to move downward. Under the guiding action of the clamping guide block 26, the locking device 27 is clamped to prevent the locking device 27 from continuing to rotate, playing a role in anti-theft. When the whole device needs to be removed, a magnet with opposite magnetism can be placed in the middle of the top surface of the top cover 11. At this time, the magnet 25 moves upward under the action of magnetic force, releasing the restriction on the locking block 271. At this time, rotating the top rotating block 276 in the reverse direction can release the clamping of the whole device. Then, by grasping the water outlet 135 opened on the side of the lifting rod 134 and lifting the water outlet 135, the whole device with the released clamping can be lifted.
[0035] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
