At this time, rotating the rotating handle 202 can drive the right-side threaded column 104 to rotate, and then the hatch cover body 102 can be manually opened and closed. Even if the electrical components are damaged, the cargo can be stored and retrieved normally, thereby ensuring that the cargo storage and retrieval efficiency will not be affected by the damage to the electrical components.

[0028] Example 2

[0029] Reference Figure 2 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0030] In this embodiment, the inner cavity of the support frame 101 is provided with a accommodating cavity 107, and the rear ends of the two threaded columns 104 both penetrate into the inner cavity of the accommodating cavity 107. A DC motor 108 is fixedly connected to the right side of the back side of the inner cavity of the accommodating cavity 107, and the output shaft of the DC motor 108 is transmission-connected to the rear end of the right-side threaded column 104.

[0031] A synchronous wheel 109 is fixedly connected to the surface of the threaded column 104 and located in the inner cavity of the accommodating cavity 107. The two synchronous wheels 109 have equal diameters and are connected by a synchronous belt transmission.

[0032] like Figure 2As shown, when the DC motor 108 is running, it can drive the right threaded column 104 to rotate. Since the two synchronous wheels 109 have equal diameters and are connected by a synchronous belt transmission, when the right threaded column 104 rotates, it can cooperate with the two synchronous wheels 109 to drive the left threaded column 104 to rotate, so that the two threaded columns 104 rotate synchronously, and then the positions and angles of the two threaded sleeves 105 and the adjustment plate 106 can be adjusted synchronously, so that the hatch body 102 can be opened or closed smoothly.

[0033] Example 3

[0034] Reference Figure 1-3 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0035] In this embodiment, a movable ring 205 is slidably connected to the surface of the rotating handle 202 and the inner cavity of the accommodating groove 201, and both sides of the back of the movable ring 205 are movably connected to support frames 206 through bearings, and the sides of the two support frames 206 that are close to each other are fixedly connected to the docking plate 203.

[0036] A through slot 207 is provided on the right side of the support frame 101 . The inner cavity of the through slot 207 is movably connected to a threaded rod 208 through a bearing. The surface of the threaded rod 208 is threadedly connected to a threaded plate 209 . The left side of the threaded plate 209 is fixedly connected to the movable ring 205 .

[0037] A rotating block 210 is fixedly connected to the surface of the threaded rod 208 and located at the rear end of the threaded plate 209 , and a limiting plate and an anti-sliding block are fixedly connected to the surface of the rotating block 210 .

[0038] like Figure 1-3 As shown, by rotating the rotating block 210, the threaded rod 208 can be driven to rotate. When the threaded rod 208 rotates, the position of the threaded plate 209 can be adjusted. The threaded plate 209 then drives the movable ring 205 to move, so that the docking plate 203 can be inserted into the inner cavity of the slot 204, so as to dock the right threaded column 104 and the rotating handle 202, so that the two can rotate synchronously. The limit plate and the anti-sliding block facilitate the rotation of the rotating block 210 and prevent slipping during rotation.

[0039] During use, when the hatch cover body 102 needs to be opened or closed under normal conditions, the DC motor 108 can be started. The output shaft of the DC motor 108 can drive the right threaded column 104 to rotate. Since the two synchronous wheels 109 have equal diameters and are connected by a synchronous belt transmission, when the right threaded column 104 rotates, it can cooperate with the two synchronous wheels 109 to drive the left threaded column 104 to rotate, so that the two threaded columns 104 rotate synchronously, and then the positions and angles of the two threaded sleeves 105 and the adjustment plate 106 can be adjusted synchronously, so that the hatch cover body 102 can be opened or closed smoothly. When the DC motor 108 is damaged and cannot operate normally, the hatch cover body needs to be opened manually. 102, first rotate the rotating block 210, the rotating block 210 can drive the threaded rod 208 to rotate, and the threaded rod 208 can adjust the position of the threaded plate 209 when rotating, and the threaded plate 209 then drives the movable ring 205 to move, so that the docking plate 203 can be inserted into the inner cavity of the slot 204, so as to dock the right threaded column 104 and the rotating handle 202, so that the two can rotate synchronously. At this time, rotating the rotating handle 202 can drive the right threaded column 104 to rotate, and the right threaded column 104 cooperates with the two synchronous wheels 109 to drive the left threaded column 104 to rotate, so that the two threaded columns 104 rotate synchronously, thereby achieving the purpose of manually opening or closing the hatch cover body 102.
