Rotation, when this is in contact with it the second turnover panel 3200 and is in moving condition, between the second turnover panel 3200 and support wheel 3500
Rolling friction can more easily complete the movement for folding or being unfolded so as to reduce frictional force.
In the present embodiment, the line between this 2 support wheels 3500 is parallel with shaft 3400.Wherein, support wheel 3500
Lower than height locating for shaft 3400, this to fold completely in the first turnover panel 3100 and the second turnover panel 3200 locating height
Afterwards, the first turnover panel 3100 and the second turnover panel 3200 will not protrude from the upper surface of framework.
To drive shaft 3400 to rotate, worm screw, shaft 3400 are fixedly installed on the output shaft of turn drive motor 3600
Upper synchronous rotation is provided with worm gear, worm and wheel engagement.
Wherein, in the present embodiment, be it is more intuitive and clearly structure is illustrated, shaft is not shown in Fig. 3
Opening and closing driving mechanism is not shown in 3400 and turn drive motor 3600, Fig. 7.
Referring to Fig. 8, Fig. 9 and Figure 10, the table structure is flexible, can reduce occupied space, facilitates storage and transport.
Since desk includes openable and closable first plywood 2100 and the second plywood 2200 and folding first turnover panel
3100 and second turnover panel 3200, it is possible to make the minimum of desk by operating as follows: make to be unfolded by opening and closing driving mechanism
The first turnover panel 3100 and the second turnover panel 3200 fold;Later, starting, which can congratulate driving mechanism, makes open 2100 He of the first plywood
Second plywood 2200 closure.To prevent the first plywood 2100 and the second plywood 2200 to the first turnover panel 3100 and the second turnover panel 3200
Folding interfere, the first plywood 2100 and the second plywood 2200 phase again can be made by opening and closing driving mechanism before being folded
Carry on the back mobile a distance.At this point, the usable floor area of desk is small, demand when can satisfy fewer in number.
When need to meet number it is more in the case where using the needs of desk when, then can proceed as follows: by opening
Closing driving mechanism opens the first plywood 2100 of closure and the second plywood 2200, and turns over spacing between the two greater than first
The width of plate 3100 and the second turnover panel 3200;Later, start turn drive motor 3600, so that 3100 He of the first turnover panel folded
The expansion of second turnover panel 3200, at this point, the upper surface of the first turnover panel 3100 and the second turnover panel 3200 is upward, and the two is supported on
In framework 1100.
In the present embodiment, positioning pin can be set in the opposite side of the first plywood 2100 and the second plywood 2200,
Correspondingly, the first turnover panel 3100 and the second turnover panel 3200 are set relative to two sides of the first plywood 2100 and the second plywood 2200
It is equipped with and the one-to-one location hole of positioning pin, wherein positioning pin and location hole clearance fit.In the first turnover panel 3100 and second
After turnover panel 3200 is fully deployed, positioning pin on the first plywood 2100 and the second plywood 2200 is respectively aligned to the first turnover panel 3100
With the location hole of second 3,200 two sides of turnover panel, it finally can also restart an opening and closing driving mechanism, so that the first plywood
2100 and second plywood 2200 move towards, until be bonded completely with the first turnover panel 3100 and the second turnover panel 3200, meanwhile, make phase
In the positioning pin insertion location hole answered, so that the first plywood 2100, the second plywood 2200, the first turnover panel 3100 and second turn over
Plate 3200, four when in a horizontal state, can keep it is more stable also, avoid during using desk, first
The case where turnover panel 3100 and the second turnover panel 3200 are overturned.
Due to being provided with positioning pin and location hole, then also being needed before folding the first turnover panel 3100 and the second turnover panel 3200
Starting an opening and closing driving mechanism is moved away from the first plywood 2100 and the second plywood 2200, so that positioning pin is from location hole
It completely disengages, later, can just facilitate the folding work for executing the first turnover panel 3100 and the second turnover panel 3200.
In the present embodiment, framework 1100 can choose using rectangle frame.Wherein, table leg 1200 may be provided with 4, and divide
It is placed on four corners of framework 1100.
