The structural states of fig. 16(1), fig. 11-13 and fig. 2 correspond to each other, which is a schematic connection structure of each component when the device is not unfolded, at this time, the first rack 202d is meshed with the third gear 202c, and the teeth of the fourth gear 203a are located in the stop zone 203b-2 of the second rack 203b, and the structural states of fig. 16(2), fig. 14 and fig. 3 correspond to each other, which is a schematic connection structure of each component when the device is unfolded at the first stage, at this time, the first rack 202d is meshed with the third gear 202 c.
The specific process from undeployed to first-stage deployment is that the convex edges 101f-4 are pulled towards two sides, the first rack 202d drives the third gear 202c to rotate so that the main board rises to the position shown in fig. 2, when the main board stops, the end stop block of the first rack 202d contacts the side edge of the box body 101, the first rack 202d cannot move outwards any more, and meanwhile, the first rack 202d exceeds the range of the third gear 202c and is not meshed with the third gear 202c, as shown in fig. 16 (2); and because the teeth of the fourth gear 203a are located in the stop region 203b-2 of the second rack 203b, the second rack 203b does not affect the rotation of the third gear 202c in the process.
Fig. 16(3), fig. 15 and fig. 4 correspond to the structural states, which are schematic of the connection structure of the components when the device is expanded in the second stage, and the specific process from the first stage to the second stage is that after the first stage is expanded, the toggle block 203b-1 is toggled to move the second rack 203b to both sides, in this process, the fourth gear 203a reaches the transmission area 203b-2 from the stop area 203b-2, the fourth gear 203a is engaged with the second rack 203b, the fourth gear 203a is rotated by the movement of the second rack 203b, because the third gear 202c is coaxially arranged with the fourth gear 203a, the third gear 202c rotates, and in the first stage expansion process, the first rack 202d is disengaged from the third gear 202c, and therefore, the first rack 202d will not affect the second stage expansion process; then the main plate 102 is continuously lifted under the trigger transmission of the second rack 203b,
the flange 101f-4 is configured to facilitate the application of force to the flange 101f-4 by a user.
The lateral surface of the second rack 203b is also provided with a transverse groove, and the transverse groove is connected with a transverse boss arranged on the lateral wall of the second lateral groove 101c to support and limit the second rack 203 b.
The process of closing the device is to first retract the second rack 203b and then retract the top plate 101 f.
