Fig. 4 is the stereo amplification figure of the utility model dipteron formula perpetual calendar counter neutral gear.
Fig. 5 is the three-dimensional assembly diagram of the utility model dipteron formula perpetual calendar counter.
Embodiment
Please refer to Fig. 1 to Fig. 5, this dipteron formula perpetual calendar counter comprises base plate 10, be installed in loading plate 20 in this base plate 10, be installed in left wing plate 30 on the loading plate 20 and right wing plate 40, neutral gear 50 and the shade top cover 60 on loading plate 20 tops.
This base plate 10 is ellipticity substantially.
This loading plate 20 is embedded in base plate 10, and the end face of these loading plate 20 bottoms is provided with keys of computer (not label), and the bottom surface of bottom is provided with the circuit board (figure does not show) of counter and perpetual calendar; The projection 28 of the outstanding cylindrical shape of these loading plate 20 center upper portion, loading plate 20 center upper portion are provided with a reference column 26 near the place, below of this projection 28, these loading plate 20 top peripheries are provided with three fixed orifices 22, offer the stopper slot 24 of fan arc near the left side of projection 28.
This left wing plate 30 has a disk 31, and its central authorities offer cylindrical hole 36, and cylindrical hole 36 peripheries are convexly equipped with flange 34.Form one section internal tooth 38 on the inner periphery of this disk 31, bend out a L shaped positive stop hook 32 (can with reference to figure 3) downwards near an end of internal tooth 38 on the disk 31; This disk 31 is connected with left wing 33.
This right wing plate 40 has a disk 41, and its central authorities offer cylindrical hole 46, forms one section external tooth 48 between the inner periphery of this disk 41 and the cylindrical hole 46; This disk 41 is connected with right flank 43.
Please refer to Fig. 4, this neutral gear 50 has chassis 52, forms one section gear teeth 522 on its excircle, form on the chassis 52 with this chassis 52 concentric take over a business 54, take over a business also to form one section gear teeth 542 on 54 excircles, chassis 52 offers axis hole 51 with the circle centre position of taking over a business 54.
These top cover 60 inside surfaces stretch out three fixed legs 62 downwards.
Loading plate 20 is housed in the base plate 10, and the cylindrical hole 36 of left wing plate 30 is set in projection 28 outsides of loading plate 20, and positive stop hook 32 is located in the stopper slot 24, makes that left wing plate 30 can be with respect to loading plate 20 rotations; The cylindrical hole 46 of right wing plate 40 is set in flange 34 outsides of left wing plate 30, makes that right wing plate 40 can be with respect to left wing plate 30 rotations; The axis hole 51 of this neutral gear 50 is movably set in reference column 26 outsides of loading plate 20, and internal tooth 38 engagements of the gear teeth on its chassis 52 522 and left wing plate 30, takes over a business external tooth 48 engagements of the gear teeth 542 and right wing plate 40 on 54; Three fixed legs 62 of top cover 60 are fixed in the fixed orifice 22 of loading plate 20.Thereby all component-assembled are got up.
Owing to left wing plate 30 and right wing plate 40 intermesh by neutral gear 50, when with left wing plate 30 (right wing plate 40) when outwards rotating to an angle, right wing plate 40 (left wing plate 30) also can rotate to an angle simultaneously in the opposite direction simultaneously, thereby guarantees that two wing plates can open identical angle simultaneously; The amplitude of opening is then owing to the position limitation of the positive stop hook on the left wing plate 30 32 in the stopper slot 24 of loading plate 20 has suitable maximum open angle.
This apparatus structure is simple, and volume is small and exquisite, and has two wings, has certain specious degree.
