Embodiment
Please refer to Fig. 1 to Fig. 3, it has disclosed the hydraulic pressure turning gear 10 of first embodiment of the invention.This turning gear 10 comprises shell 11, piston 12, transmission shaft 13, elasticity blocking piece 14 and bearing 15.Its middle (center) bearing 15 is installed on the two ends of shell 11 and surrounds a Seal cage 101 with shell 11, full of liquid in the sealing chamber 101, piston 12 is divided into first chamber 102 and second chamber 103 with Seal cage 101, and transmission shaft 13 is installed on the piston 12 and passes sealing chamber 101.
This shell 11 is cylindric, be formed with a plurality of vertical guide grooves 111 on the internal surface of shell 11 vertically, the two ends of the internal surface of shell 11 are formed with screw thread, the peripheral surface of shell 11 is provided with a plurality of fixed blocks 113, be formed with fixed hole on the fixed block 113, be used for shell 11 is fixed to the body (figure does not show) of an electronic equipment.
This piston 12 is circular, comprises that the tapped through hole 121 that runs through both ends of the surface and two are through the passage 122 of first chamber 102 and second chamber 103 and be arranged at raised line 123 on the outer circumferential face.Please refer to Fig. 3, the diameter of these passage 122 1 ends diminishes gradually, is frusto-conical, and the other end is formed with screw thread, two passages 122 opposite toward each other.This raised line 123 matches with vertical guide groove 111 of shell 11, makes the piston 12 can only be along the axial motion of shell 11.
This elasticity blocking piece 14 is in the passage 122 of piston 12, is used for this passage 122 of shutoff.Pressure on acting on elasticity blocking piece 14 is during less than a predetermined value, passage 122 shutoff; Pressure on acting on elasticity blocking piece 14 is during greater than predetermined value, and elasticity blocking piece 14 is compressed, and passage 122 is opened.In the present embodiment, elasticity blocking piece 14 comprises a spheroid 141, an elastic component 142 and a screw 143.This spheroid 141 is in the end that passage 122 diameters diminish, this screw 143 hollows and be installed on passage 122 screwed ends, this elastic component 142 is between this spheroid 141 and screw 143, and under the elastic force effect of elastic component 142, spheroid 141 stops up this passage 122.
Be formed with outside thread on this bearing 15, bearing 15 is installed on the two ends of shell 11 by this external thread spiro fastening, between shell 11 and bearing 15 seal washer 16 is installed also.
This transmission shaft 13 is formed with screw thread 131 at axial middle part, and an end 132 of transmission shaft 13 is polygonal column.Transmission shaft 13 is installed on the bearing 15, and screw thread 131 screws togather with the tapped through hole 121 of piston 12.This end 132 of transmission shaft 13 passes bearing 15 and reaches outside the shell 11, and cooperates with the polygonal hole 171 of a pivoted arm 17.This pivoted arm 17 is fixed in (figure does not show) on the lid of an electronic equipment, rotates this pivoted arm 17, and transmission shaft 13 rotate thereupon, because transmission shaft 13 and piston 12 screw togather, the rotation of transmission shaft 13 can drive the axial motion of piston 12 along transmission shaft 13.
When not rotating pivoted arm 17, elasticity blocking piece 14 is with passage 122 complete shutoff, and first chamber 102 of Seal cage 101 and second chamber 103 are isolated mutually, and liquid can not circulate in first chamber 102 and second chamber 103 mutually.When clockwise promotion pivoted arm 17, transmission shaft 13 turns clockwise, drive piston 12 to 102 motions of first chamber, compress the liquid of first chamber 102, pressure in first chamber 102 increases, producing a resistance stops pivoted arm 17 to rotate, when pressure is increased to above predetermined value, the spheroid 141 of liquid compressing elasticity blocking piece 14, spheroid 141 is to second chamber, 103 motion and compression elastic pieces 142, first chamber 102 and second chamber 103 of Seal cage 101 connect mutually, and this moment, liquid can be in first chamber 102 and 103 circulations of second chamber, and pivoted arm 17 can be rotated.When stopping the rotation pivoted arm 17, spheroid 141 moves to first chamber 102 under the effect of elastic component 142, blocking channel 122, and liquid can not circulate in first chamber 102 and second chamber 103 mutually, and rotating shaft 10 is fixed on current location.
In the above-described embodiment, pivoted arm 17 is not limited only to turn clockwise, and can be rotated counterclockwise, and principle is identical.
Please refer to Fig. 4 and Fig. 5, it has disclosed the hydraulic pressure turning gear 10 ' of second embodiment of the invention, this hydraulic pressure turning gear 10 ' is similar to the hydraulic pressure turning gear 10 in first mode of execution, different places is (because the symmetrical configuration among Fig. 4 and Fig. 5, below only the structure among Fig. 4 is described):
The passage 122 ' that connects first chamber 102 ' and second chamber 103 ' is formed on the shell 11 ', each passage 122 ' opposite shell 11 ' axisymmetric, it is big that passage 122 ' one end volume becomes, this end forms the aperture 104 ' of a connection first chamber 102 ', the structure of the passage 122 among this aperture 104 ' and first embodiment is identical, the elasticity blocking piece 14 ' identical with elasticity blocking piece 14 among first embodiment is arranged in this aperture 104 ' and stops up this aperture 104 ', thus blocking channel 122 '.
Rotating shaft 10 ' also comprises Sealing 19 ', sealing part 19 ' comprises a seal ring 191 ' and the adjutage 192 ' that is extended out by seal ring 191 ', sealing circle 191 ' is socketed on the transmission shaft 13 ' versatilely, this adjutage 192 ' stretches in the passage 122 ', and comprises the inclined-plane 193 ' that contacts with the spheroid 141 ' of elasticity blocking piece 14 '.Sealing 19 ' and shell 11 ' cooperate, thereby form Seal cage 101 '.
Rotating shaft 10 ' also is with elastic component 18 ', and this elastic component 18 ' is between seal ring 191 ' and the bearing 15 '.When pivoted arm 17 ' did not rotate, the adjutage 192 ' that elastic component 18 ' orders about Sealing 19 ' goed deep into passage 122 ', thereby the spheroid 141 ' of elasticity blocking piece 14 ' can not oppressed in inclined-plane 193 '.
When not rotating pivoted arm 17 ', elasticity blocking piece 14 ' is with passage 122 ' complete shutoff, and first chamber 102 ' of Seal cage 101 ' and second chamber 103 ' are isolated mutually, and liquid can not circulate in first chamber 102 ' and second chamber 103 ' mutually.When clockwise promotion pivoted arm 17 ', transmission shaft 13 ' turns clockwise, and drives piston 12 ' to the 102 ' motion of first chamber, compresses the liquid of first chamber 102 ', thereby promotes Sealing 19 ' to bearing 15 ' direction.During not greater than the resistance of elastic component 18 ', elastic component 18 ' produces resistance and stops Sealing 19 ' motion, thereby stops pivoted arm 17 ' rotation in thrust; When thrust during greater than the resistance of elastic component 18 ', seal ring 191 ' is to bearing 15 ' motion, inclined-plane 193 ' compression spheroid 141 ' on the adjutage 192 ', the feasible passage 122 ' perforation mutually that runs through first chamber 102 ' and second chamber 103 ' of Seal cage 101 ', this moment, liquid can circulate between first chamber 102 ' and second chamber 103 ', rotation pivoted arm 17 ', rotating shaft 10 ' is rotated.When stopping the rotation pivoted arm 17 ', Sealing 19 ' moves right under the effect of elastic component 18 ', and inclined-plane 193 ' leaves spheroid 141 ', and spheroid 141 ' moves upward under the effect of the elastic component 142 ' of elasticity blocking piece 14 ', blocking channel 122 ', rotating shaft 10 ' is positioned at the fixed position.
In the above-described embodiment, pivoted arm 17 ' is not limited only to turn clockwise, and can be rotated counterclockwise, and principle is identical.
