[0023] Please refer to Figure 2 The hinge 3 comprises a connecting plate 31 and a mounting plate 32, the connecting plate 31 is fixedly connected with the door panel 1, the mounting plate 32 is fixedly connected with the door frame 2, one end of the mounting plate 32 close to the door panel 1 is fixedly installed with a ball screw 4, the connecting plate 31 is movably sleeved with the ball screw 4, the bottom of the connecting plate 31 outside the ball screw 4 is rotatably connected with the top of a ball nut 5, the ball nut 5 is spirally raised along the ball screw 4, thereby pushing the connecting plate 31 and the door panel 1 to rise, the door panel 1 is lifted a distance from the ground, the outer wall at the top of the ball screw 4 is a smooth rod, so as to prevent the connecting plate 31 from continuously rising to the top along the ball screw 4, and the ball nut 5 and the ball screw 4 are damaged due to mutual extrusion.

[0024] Please refer to Figure 3 and Figure 4 The lower part of the connecting plate 31 is transversely provided with a sliding groove I 311, a sliding block 6 is arranged in the sliding groove I 311, the sliding block 6 is movably connected with the connecting plate 31, the sliding block 6 is movably sleeved with a clamping block I 61, a compression spring 62 is arranged between the inner side end of the clamping block I 61 and the inner wall of the sliding block 6, the two ends of the compression spring 62 are fixedly connected with the clamping block I 61 and the side wall of the sliding block 6 respectively, a blind hole 51 is circumferentially arranged on the side wall of the ball nut 5, the blind hole 51 is located at the same height as the clamping block I 61, and the shape of the blind hole 51 is matched with the shape of the outer end of the clamping block I 61, the sliding block 6 is pushed to the ball nut 5 to make the clamping block I 61 tightly contact with the side wall of the ball nut 5, the door panel 1 is rotated to drive the connecting plate 31 and the sliding block 6 to move synchronously, when the clamping block I 61 passes through the blind hole 51, the clamping block I 61 enters the blind hole 51 under the elastic force of the compression spring 62, so that the ball nut 5 rotates synchronously with the door panel 1 and the connecting plate 31, and the ball nut 5 lifts the connecting plate 31 and the door panel 1 to climb upward along the ball screw 4.

[0025] Please refer to Figure 3 and Figure 5, the side wall of the ball nut 5 above the blind hole 51 is provided with a clamping block II 52 in the circumference, the structure of the clamping block II 52 is same with the clamping block I 61, the clamping block II 52 is movably connected with the ball nut 5, a spring for pushing the clamping block II 52 out is arranged in the clamping block II 52, the spring is used for pushing the clamping block II 52 out and resetting, the function of the spring is same with the compression spring 62. A sliding groove II 321 is horizontally arranged on the side wall of the mounting plate 32 at the same height corresponding to the clamping block II 52, the sliding groove II 321 is located on the upper side of the shaft center of the ball screw 4 (taking the direction as an example), a limiting column 7 is arranged in the sliding groove II 321, the limiting column 7 is movably connected with the mounting plate 32, the limiting column 7 is moved to one end of the sliding groove II 321 close to the ball nut 5, when the clamping block II 52 passes through the limiting column 7, the clamping block II 52 is tightly abutted against the side surface of the limiting column 7, so that the ball nut 5 is prevented from rotating back. Figure 5

[0026] The use method (working principle) of the utility model is as follows:

[0027] When the bottom surface of the door plate 1 is embedded with sundries and the sundries cannot be taken out, the sliding block 6 is pushed to the direction of the mounting plate 32, the clamping block I 61 is tightly abutted against the outer wall of the ball nut 5, and the limiting column 7 is moved to one end of the sliding groove II 321 close to the ball nut 5. The door plate 1 is opened, the door plate 1 drives the connecting plate 31 and the sliding block 6 to synchronously rotate, when the clamping block I 61 passes through the blind hole 51, the clamping block I 61 enters the blind hole 51 under the elastic force of the compression spring 62, the door plate 1 and the connecting plate 31 drive the ball nut 5 to synchronously rotate, the ball nut 5 climbs upwards along the ball screw 4 and simultaneously lifts the connecting plate 31 and the door plate 1 above to move upwards, and the door plate 1 is lifted away from the ground.

[0028] When the door plate 1 is opened and then closed, the door plate 1 and the hinged part 3 drive the sliding block 6 to rotate back, the ball nut 5 cannot rotate back due to the abutment and limiting of the side wall of the limiting column 7 to the side wall of the clamping block II 52, the door plate 1, the connecting plate 31 and the ball nut 5 stop rising, the clamping block I 61 moves back with the connecting plate 31 and is separated from the original blind hole 51. The door plate 1 is opened and closed repeatedly, so that the door plate 1, the mounting plate 32 and the ball nut 5 continuously rise, until there is enough space between the bottom surface of the door plate 1 and the bottom surface to take out the sundries.

[0029] After the sundries are cleaned, the door plate 1 is slightly opened, the limiting column 7 is separated from the clamping block II 52, the limiting column 7 is pushed to one end far away from the ball nut 5, the ball nut 5 loses the limiting and rotates under the action of gravity, the ball nut 5 can also be pushed to accelerate the rotation, the door plate 1, the connecting plate 31 and the ball nut 5 fall to the original position, the sliding block 6 is reset, the door plate 1 is repeatedly opened and closed without driving the ball nut 5 to rotate, and the door plate 1 does not float up and down to wear the door frame 2 in normal use.​
