Embodiment
See also Fig. 1 and Fig. 2; The utility model provides a kind of twin axle pivot device of tool limit function; Be arranged at one have a loam cake and a base folding electronic product (figure does not show), it mainly is made up of one first rotating shaft 11, one second rotating shaft 12, one first torque force device 21, one second torque force device 22, one first fixing frame 31, one second fixing frame 32, a stop mechanism 40 and 50 of limit structures.
First rotating shaft 11 of the utility model has a first axle part 111 and one first joint 112, and second rotating shaft 12 has a second axle part 121 and one second joint 122.First rotating shaft 11 and second rotating shaft 12 laterally arrange in the axial direction.
Wherein first torque force device 21 is arranged on the first axle part 111 rotary torsion is provided, and second torque force device 22 is arranged on the second axle part 121 rotary torsion is provided.First torque force device 21 and second torque force device 22 have a plurality of shell fragments 211,221 that are socketed on the first axle part 111 and the second axle part 121 respectively, and sealed and fixing with a set screw nut 212,222 and the first axle part 111 and the second axle part 121 respectively.First torque force device 21 and second torque force device 22 are oppressed one first auto-closing wheel, 213 and 1 second auto-closing wheel 223 respectively, make the relative base of loam cake when closed state and maximum opening state, have the auto-closing function.First auto-closing wheel, 213 and second auto-closing wheel 223 contacts with support plate 512 outer side surfaces respectively, and is respectively equipped with corresponding projection 213a, 223a (shown in Figure 1A) and recess 512a on the surface of contact betwixt, to reach the auto-closing function; This function can be referring to explaining in the case before relevant.
The utility model first fixing frame 31 lock seaming are in loam cake, and fixedly sleeved and together rotate with first joint 112 of first rotating shaft 11.Second fixing frame, 32 lock seaming are in base, and with second joint 122 of second rotating shaft 12 fixedly sleeved and with together rotate.
The person of advancing, limit structure 50 has a pair of support plate 511,512, is provided with one first limit cam 521, one second limit cam 522 and a transfer strip 53 betwixt.First limit cam 521 is provided with one first position-limitting mouth 521a and is sheathed on the first axle part 111 and together rotates, and second limit cam 522 is provided with one second position-limitting mouth 522a and be sheathed on the second axle part 121 and together rotate.Transfer strip 53 has the wheel portion 533 that can swing; Be articulated on support plate 511 and 512 with the minor axis 534 of both sides and can swing, and establish one first limiting stopper 531 and one second limiting stopper 532 between first limit cam 521 and second limit cam 522 to evagination in wheel portion 533.
When the 411 and first backstop salient point 511a interference of first backstop wheel, transfer strip 53 swings embed in the first position-limitting mouth 521a first limiting stopper 531, limit first rotating shaft 11 and can't rotate, and only second rotating shaft 12 is rotatable; When the 412 and second backstop salient point 511b interference of second backstop wheel, transfer strip 53 swings, second limiting stopper 532 embeds in the second position-limitting mouth 522a, limits second rotating shaft 12 and can't rotate, and only first rotating shaft 11 is rotatable.Its action is with following explanation.
In addition; Prominent respectively a pair of first guide block 531a and a pair of second guide block 532a of establishing in first limiting stopper 531 on the transfer strip 53 of limit structure 50 and second limiting stopper, 532 bi-side; Should together rotate and the second guide block 532a stretches into this respectively in the guide groove 511c that offers respectively on the support plate 511,512, the 512c the first guide block 531a, with restriction transfer strip 53 hunting ranges.
See also the breakdown action figure of Fig. 3 to the utility model shown in Figure 6.Shown in Fig. 3; Also cooperate shown in Figure 7ly, tie up to loam cake and base at closed state, just 0 when spending; Because second limiting stopper 532 of transfer strip 53 embeds in the second position-limitting mouth 522a; Limiting second rotating shaft 12 can't rotate, and only first rotating shaft 11 can be rotated shown in arrow, and the relative base of loam cake is opened.Referring to shown in Figure 4; When first rotating shaft 11 turns to 120 when spending, second fixing frame 32 turns to solid line position from dotted line position, cooperates shown in Figure 8; The first sector unit 411a of first backstop wheel 411 keeps out mutually with the first backstop salient point 511a and produces interference, and first rotating shaft 11 can not be rotated again.
As open the application of force again; Then, utilize second limit cam, 522 outer rims to push against second limiting stopper 532 because second limiting stopper 532 of second position-limitting mouth 522a of second limit cam 522 and transfer strip 53 begins to break away from, as shown in Figure 5; Transfer strip 53 is swung to arrow G 1 direction; Make first limiting stopper 531 embed the first position-limitting mouth 521a of first limit cam 521, limit first rotating shaft 11 and can't rotate, only second rotating shaft 12 is rotatable; At this moment, rotate second rotating shaft 12 to 180 degree, make second fixing frame 32 turn to solid line position from dotted line position.Though first rotating shaft 11 has its rotation of backstop of stop mechanism 40 on opening direction; If first limiting stopper 531 of limit structure 50 does not embed in the first position-limitting mouth 521a of first limit cam 521; When reversed closed action, first rotating shaft 11 possibly misrouted moving, cause action to have some setbacks.
Afterwards, as shown in Figure 6, because second rotating shaft 12 is not limited and sustainable rotation, it is as shown in the figure to upper/lower positions that second fixing frame 32 is rotated to.
In like manner, when reversed closed action, because second rotating shaft 12 is not limited and can rotates earlier; But when going to when being similar to position shown in Figure 4; The second sector unit 412a and the second backstop salient point 511b of second backstop wheel 412 keep out and interference in the stop mechanism 40 at this moment, and second rotating shaft 12 can not be rotated, and close the application of force as opening again; Then because first limiting stopper 531 of first position-limitting mouth 521a of first limit cam 521 and transfer strip 53 begins disengaging; Utilize first limit cam, 521 outer rims to push against first limiting stopper 531 and make transfer strip 53 swings, make second limiting stopper 532 embed the second position-limitting mouth 522a of second limit cam 522, limit second rotating shaft 12 and can't rotate; Only first rotating shaft 11 is rotatable, and goes to operating position as shown in Figure 3.
Apparently; The utility model utilizes the interoperation of stop mechanism 40 and limit structure 50; When closure or openness move, first rotating shaft 11 and second rotating shaft 12 can be rotated in regular turn, rotate moment amounts of rotation difference simultaneously and cause the speed speed drop to be arranged and move the problem that has some setbacks and got rid of; No matter make and when closure or openness move, good operating effect to be arranged.
To sum up institute is old, and the twin axle pivot device of the tool limit function that the utility model provided meets patent novelty and progressive important document fully, files an application in the whence in accordance with the law.
