[0045] The active mechanism 3 includes an opening active rod 31, a closing active rod 32, an opening abutting structure 33, a closing abutting structure 34, an opening abutting plate 35 and a closing abutting plate 36. The opening active rod 31 and the closing active rod 32 are respectively slidably arranged in each of the fixed plates 11 along the length direction of the fixed plate 11. The opening active rod 31 and the closing active rod 32 are respectively provided with a pressing portion 37 at one end close to the sliding end 211. The pressing portion 37 extends out of the fixed plate 11. The two rotating plates 23 are respectively provided with ends of the openings 232 that are rotatably connected to one end of the two fixed plates 11 close to the pressing portion 37. The opening abutting structure 33 and the closing abutting structure 34 are respectively arranged in each of the fixed plates 11. The fixed plate 11 is provided with a accommodating groove 111 for accommodating the opening abutting structure 33 / closing abutting structure 34. The opening active rod 31 / the closing active rod 32 is respectively abutted against the opening abutting structure 33 at one end away from the pressing portion 37. The abutment structure 33 / closing abutment structure 34, the opening abutment plate 35 / closing abutment plate 36 are arranged on the rotating plate 23 and the opening abutment plate 35 / closing abutment plate 36 are respectively arranged close to the opening abutment structure 33 / closing abutment structure 34. When the pressing portion 37 arranged on the opening active rod 31 is pressed, the opening active rod 31 pushes the opening abutment structure 33, the opening abutment structure 33 pushes the opening abutment plate 35, and the opening abutment plate 35 drives the rotating plate 23 to rotate to a position where the horizontal height of the slide-out end 211 is lower than the position of the end of the drawer body 21 away from the slide-out end 211. When the pressing portion 37 arranged on the closing active rod 32 is pressed, the closing active rod 32 pushes the closing abutment structure 34, the closing abutment structure 34 pushes the closing abutment plate 36, and the closing abutment plate 36 drives the drawer body 21 to rotate to a position where the horizontal height of the slide-out end 211 is higher than the position of the end of the drawer body 21 away from the slide-out end 211.

[0046] Specifically, the opening abutment structure 33 / closing abutment structure 34 includes a rotating active rod 331 and a rotating driven rod 332. The end of the rotating driven rod 332 away from the pressing portion 37 is hinged to the side of the lower end of the accommodating groove 111 away from the pressing portion 37. The end of the rotating active rod 331 away from the pressing portion 37 is hinged to the middle of the rotating driven rod 332. The end of the rotating active rod 331 close to the pressing portion 37 is slidably connected to the bottom end of the side wall of the accommodating groove 111 through a sliding column 333. The side wall of the accommodating groove 111 is provided with two second sliding grooves along the length direction of the fixed plate 11 for respectively accommodating the two ends of the sliding column 333.

[0047] The notch of the accommodating groove 111 provided with the opening abutment structure 33 is set vertically upward, and the notch of the accommodating groove 111 provided with the closing abutment structure 34 is set vertically downward. When the pressing portion 37 set on the opening active rod 31 is pressed, the closing abutment plate 36 approaches and covers the notch of the accommodating groove 111, and the projection of the notch of the accommodating groove 111 on the closing abutment plate 36 completely falls into the closing abutment plate 36. When the pressing portion 37 set on the closing active rod 32 is pressed, the opening abutment plate 35 approaches and abuts the notch of the accommodating groove 111, and the projection of the notch of the accommodating groove 111 on the opening abutment plate 35 completely falls into the opening abutment plate 35.

[0048] When the drawer body 21 is in a closed state, the center of gravity of the drawer body 21 is located in the middle of the two rotating plates 23. Because the rotating point of the rotating plate 23 is located at the end with the opening 232, the horizontal height of the end of the drawer body 21 away from the slide-out end 211 is lower than the slide-out end 211 under the action of gravity. At this time, the opening abutment plate 35 is in a position abutting against the opening abutment mechanism and the closing abutment plate 36 is in a position away from the closing abutment mechanism. In the process of pushing the opening active rod 31, the opening active rod 31 pushes the rotating active rod 331, and the end of the rotating active rod 331 away from the rotating driven rod 332 moves along the pushing direction toward the direction close to the rotating driven rod 332 through the sliding column 333, and the rotating driven rod 332 is moved to the direction close to the rotating driven rod 332. The end of the rotating active rod 331 hinged by the moving rod 332 close to the pressing portion 37 is lifted by the rotating driven rod 332, and the rotating driven rod 332 abuts against the opening abutment plate 35 and lifts the rotating plate 23. The rotating plate 23 drives the drawer body 21 to rotate around the rotating axis and the end of the drawer body 21 away from the sliding end 211 is continuously lifted and higher than the sliding end 211. At this time, the drawer body 21 slides out of the rotating plate 23 along the length direction of the first sliding groove 231 under the action of gravity, and the closing abutment plate 36 continuously moves in the direction close to the closing abutment structure 34 until it abuts against the closing abutment structure 34, completing the rotation process of the drawer body 21 around the rotating axis. The drawer body 21 slides out of the rotating plate 23 to the final position, completing the sliding out process of the drawer body 21.

[0049] When the drawer body 21 completes the rotation process when opening, the closing abutment plate 36 pushes the rotating follower rod 332 of the closing abutment structure 34 into the accommodating groove 111, and at the same time, the rotating follower rod 332 pushes the rotating active rod 331, and the rotating active rod 331 pushes the closing active rod 32 to the initial position required for closing the drawer body 21, completing the initial preparation required for closing the drawer body 21.

[0050] Similarly, the working process of the drawer body 21 from the open state to the closed state can be obtained, which will not be repeated here.

[0051] By setting the open abutment plate 35 / closed abutment plate 36 to completely cover the notch of the accommodating groove 111 when abutting against the accommodating groove 111 of the rotating plate 23, the rotation position of the rotating plate 23 when the drawer body 21 is closed / opened is limitedly supported.

[0052] In one embodiment, rolling wheels can be rotatably connected at both ends of the sliding column 333 in the second sliding groove to reduce the friction resistance of the sliding column 333 when sliding in the second sliding groove to improve the convenience of pushing the active rod 31 to open / close the active rod 32.

[0053] In one embodiment, a fixing device for fixing the equipment can be set in the drawer body 21 to ensure that the equipment does not undergo relative displacement when the drawer body 21 moves or vibrates. The fixing device can be a fixing ring, a fixing buckle, a fixing clip, etc. The specific form of the fixing device depends on the specific structure of the equipment.

[0054] In order to facilitate the opening active rod 31 / closing active rod 32 to push the rotating active rod 331, as a further improvement, the opening active rod 31 / closing active rod 32 is provided with an abutment portion 38 at one end close to the rotating active rod 331, and the abutment portion 38 is a rectangular plate perpendicular to the axis of the opening active rod 31 / closing active rod 32.

[0055] As a further improvement, a spare handle 25 is provided on the outer side of the drawer body 21 away from the opening abutment structure 33 and the closing abutment structure 34 .

[0056] In order to prevent the active mechanism 3 from malfunctioning and causing the drawer body 21 to be unable to be opened / closed, a backup handle 25 is provided. When the active mechanism 3 fails, the drawer body 21 can be opened / closed by the backup handle 25.
