Embodiment
Below in conjunction with above-mentioned accompanying drawing said stepping rotary device structure and principle are done further elaboration.
Referring to figs. 1 to Fig. 7; Shown in these accompanying drawings; The stepping whirligig of said television screen; Contain outside base plate 12, rotating shaft 3 and the axle sleeve 2, also be provided with driveshaft 15, lock pin 10, dead bolt 6, dead bolt fixed cover 13, button 4, screen link 1, spring, button nut 14 and lock pin nut 11; The left end of said driveshaft 15 is socketed with spring and lives and are connected with the pillow platform 9 on the base plate; Middle right-hand member rests on the supporting station 7 and gear 28 interlocks on teeth 19 and the axle sleeve 2 is arranged; The lower end of axle sleeve 2 be fixed on rotating shaft 3 sockets on the base plate; The top is connected with screen link 1, and said dead bolt fixed cover 13 is connected with connecting base 8 on being arranged on base plate 12, and said lock pin 10 passes strip hole 18 backs that are arranged on the driveshaft and lives and are inserted in the spacing hole 32 of dead bolt fixed cover 13 lower ends; Its lower end is with spring 52, and the other end of spring 52 offsets with the lock pin nut 11 that is connected on the base plate; Said dead bolt 6 is set in another spacing hole 31 on the dead bolt fixed cover 13, has on it and inconsistent position, lock pin 10 tops; The top of dead bolt fixed cover 13 is equipped with button 4, and 6 of button 4 and dead bolts are placed with spring 5.
The lower end of said axle sleeve 2 is connected with gear 28, and the top is provided with the attachment hole of ability and the pairing of screen link;
Said base plate 12 is provided with pillow platform 9, connecting base 8 and supporting station 7, and below connecting base, is provided with through hole 30; Said rotating shaft 3 vertically is fixed on the floor 12;
The left end of said driveshaft 15 has a cylinder bar 16; The center portion at middle part is provided with a strip hole 18 that passes upper and lower surfaces; The last trailing flank of stating strip hole 18 is provided with the straight-tooth tooth 20 of plurality of continuous, and following trailing flank is provided with some alternate lockholes 17, and the right angle of the center of lockhole 17 and said straight-tooth tooth is in the face of neat; Be Fig. 3,4 the position at dotted line ab place, the right-hand member front be provided with some teeth 19 can with gear 28 interlocks;
The top of said dead bolt fixed cover 13 is provided with button cavities 34, and the lower end is provided with two spacing holes 31,32, and 31,32 of spacing holes have the portion of joining to form dead bolt and the inconsistent space of lock pin.
Said dead bolt 6 have the middle part protruding touch platform 26; The upper and lower end face that touches platform 26 respectively has a cylinder, and the upper prop body is used for interspersed spring 5, and the bottom of lower prop is provided with an inclined plane part 24 and a vertical plane portion 25; Be tenon shape, the lower end surface of touching platform 26 is dead bolt 6 and inconsistent position, lock pin 10 tops.
The left side wall of above-mentioned lockhole 17 is straight planes, the right side wall be by at the bottom of the hole to oblique inclined-plane, aperture, and the aperture greater than the hole at the bottom of.
With reference to accompanying drawing 8,9,10,11, shown in these figure, a step cycle of said stepping whirligig is divided locking state, release threshold state, released state, four continually varying processes of locking threshold state; The working principle of these four processes is following, in above-mentioned assembly process, can know, the locking key 22 of lock pin 10 has been inserted in the said lockhole 17 during assembling; And tightly be pressed in the lockhole 17 by spring 51 locking keys 22; Promptly be in locking state this moment, and under this state, dead bolt 6 is by tongue 23 jack-up; Driveshaft can not move right (elastic force of spring pushes away driveshaft 15 from left to right); This moment as press the button 4, the dead bolt 6 promotion tongue 23 that will descend moves down, when moving down into locking key 22 and in lockhole 17, withdraw from fully just; Straight planar surface portion 25 existing sub-fractions and said straight-tooth tooth 20 right angle faces on the dead bolt 6 are interlockingly connected, and this is the release threshold state; The purpose that is provided with like this is to avoid in the process that presses the button; The bad phenomenon that screen rotates suddenly rapidly takes place; Continue to pin button and be displaced downwardly to the bottom surface that the dead bolt bottom contacts straight-tooth tooth 20 this moment; Certain distance has been withdrawed from locking key 22 this moment in lockhole 17, this is a released state, although certain distance has been withdrawed from locking key 22 this moment in lockhole 17; But owing to straight planar surface portion on the dead bolt 6 25 and straight-tooth tooth 20 right angle faces still are interlockingly connected, so driveshaft still can not move right under this state; If this moment is release button, because the spring 51 of this moment has been pressed very tightly, so its elastic force that makes progress is greater than from the downward elastic force of spring 5; So can be rapidly through tongue 23 with dead bolt 6 jack-up, just in the moment of this jack-up because dead bolt is decorporated fully required time of straight-sided flank will be slightly than required time of locking key 22 entering lockholes 17 before a bit; Move right so driveshaft is no longer restricted; When locking key 22 risings contacted driveshaft 15, just in time other touched with the inclined-plane of lockhole 17 at the top of locking key 22 distance that driveshaft moves right mutually, guarantees to get into the locking threshold state; This moment, driveshaft moved right continuing; Promote gear 28 through the teeth on its right-hand member 19 and rotate, thereby realize display screen is rotated once in set angle, when locking key 22 slides in the lockhole 17 fully along the inclined-plane; Driveshaft is locked at this, repeats to press the button also can screen progressively be rotated to the angle of wanting.When needs are done the rotation of putting direction, press the button and just can break screen off with the fingers and thumb and do backward rotation with hand, its principle is appreciated that in the structural relation of the released state of Fig. 8; Because under released state; Though driveshaft can not move right, being moved to the left is to realize, reason is under this state; Locking key 22 is fully away from lockhole 17; And the opposite on straight plane, dead bolt lower end is the inclined-plane, although straight-tooth tooth 20 also will be inconsistent with this inclined-plane in the process that moves to left, counter-rotationally carries out smoothly because spring 5 can compressed cause have ensured.
