The longitudinal direction of the fitting groove 11 is the same as the longitudinal direction of the frame 1, the width direction of the fitting groove 11 is the same as the width direction of the frame 1, and the center of the fitting groove 11 coincides with the center of the frame 1.

The steel grating plates 2 are arranged in a rectangular plate shape, and the shape and the size of the steel grating plates 2 are the same as those of the embedded grooves 11. The steel grating plate 2 has a plurality of grating through holes 21, and the grating through holes 21 can allow liquid to pass through. When the frame 1 and the steel grating plate 2 are closed, the upper end surface of the steel grating plate 2 is flush with the upper end surface of the frame 1;

further, the two side walls arranged along the length direction in the embedding groove 11 are both provided with sliding grooves 13. I.e., the number of the slip grooves 13 is two. The slide groove 13 is located at one end in the longitudinal direction of the fitting groove 11. The slide groove 13 extends along the longitudinal direction of the fitting groove 11.

The sliding groove 13 is rotatably provided with a rotating shaft 3 at one end in the embedding groove 11. The axial direction of the shaft 3 is the same as the width direction of the fitting groove 11. Both ends of the rotation shaft 3 in the axial direction are fitted into the sliding grooves 13 so that the rotation shaft 3 can slide in a direction approaching or departing from the locking grooves 12. One end of the steel grating plate 2 in the length direction is sleeved outside the rotating shaft 3 to be rotatably connected with the rotating shaft 3.

The end face of the other end of the steel grating plate 2 in the length direction is fixedly provided with a locking block 22. The locking block 22 is rectangular.

The rotation restricting block 5 is provided in a rectangular ring shape to extend into the range of the fitting groove 11. The upper end face of the rotation limiting block 5 is abutted against the end face of the steel grating plate 2 embedded in the embedded groove 11 so as to limit the turnover angle of the steel grating plate 2, prevent the steel grating plate 2 from rotating to the lower part of the frame 1 due to the overlarge turnover angle, and facilitate the opening and closing of the steel grating plate.

The upper end surface of the rotation limiting block 5 is provided with an installation groove 51 for installing the elastic piece 6, and the installation groove 51 is positioned at one end of the rotation limiting block 5 close to the locking groove 12. An elastic member 6 is provided in the mounting groove 51, and the elastic member 6 provides the steel grating plate 2 with an elastic force in a direction away from the insertion groove 11. The number of the elastic elements 6 is at least one, and all the elastic elements 6 are positioned on one side of the rotation limiting block 5 far away from the rotating shaft 3. Preferably, the third elastic member 6 is a spring. When the elastic member 6 is in a free state, the end part of the elastic member 6 extends out of the mounting groove 51, and the elastic member 6 can retract under the pressure, so that the steel grating plate 2 and the rotation limiting block 5 are attached and abutted.

When the locking block 22 is disengaged from the locking slot 12, the resilient member 6 urges the steel grating 2 to slide away from the rotation-limiting block 5, thereby facilitating the opening of the steel grating.

Further, one end of the rotation limiting block 5, which is far away from the locking groove 12, is provided with a clamping groove 52 along the vertical direction. The catching groove 52 is located at a side of the rotation axis of the rotation plate 4 adjacent to the locking groove 12. The catching groove 52 communicates with the slide groove 13.
