Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
As shown in fig. 1-5, the gravity type square lifting hole protection device comprises a square body 1, a mounting groove 2 is formed in the middle of the upper portion of the square body 1, a reserved hole 3 is formed below the mounting groove 2, the section of the reserved hole 3 is conical, a lifting hole 4 is formed in the middle of the lower end of the square body 1, the section of the lifting hole 4 is circular, the reserved hole 3 is communicated with the lifting hole 4 through a through groove 5, a cover plate 6 is arranged in the mounting groove 2 of the square body 1, a threaded rod 7 is inserted in the middle of the cover plate 6, the threaded rod 7 is movably connected with the cover plate 6, the lower portion of the threaded rod 7 extends into the lifting hole 4 and is fixedly connected with a limiting plate 8, when the threaded rod 7 rotates, the limiting plate 8 rotates along with the threaded rod 7 through transmission, two ends of the limiting plate 8 can be pressed against the inner top of the lifting hole 4, a fastening nut 9 is arranged above the cover plate 6, and when the fastening nut 9 rotates, the fastening nut 9 moves downwards and presses the cover plate 6, so that the reserved hole 3 can be stably covered on the cover plate 6.
