The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model infanette base 2 retracting mechanisms comprise many foundation pipe 1, the base 2 that articulates with those bottom tubes 1 and an operating mechanism 3 that is arranged at base 2, and this operating mechanism 3 can drive described bottom tube 1 relative base 2 and be transformed into a stowed position from an expanded position.
Shown in Fig. 2,3, described base 2 is formed with a plurality of grooves 21 around it, be formed with an accommodation space 22 in the central, and groove 21 communicates with accommodation space 22.Each groove 21 is used for ccontaining each bottom tube 1 one end, by rivet (figure does not show) or blind rivet etc. similarly connector pass hole 212 on pivoted hole 11 and base 2 grooves 21 sidewalls on the bottom tube 1, thereby each bottom tube 1 is articulated in base 2.In addition, top, groove 21 end is formed with roof 211, make bottom tube 1 when expanded position relatively base 2 rotate down.And be formed with through hole 221 on accommodation space 22 sidewalls.
Described operating mechanism 3 comprises an operating parts 4, two clamping pieces 5, a fixture 6, two first elastic components and one second elastic component, and preferably, in the present embodiment, first elastic component is that torsion spring 7, the second elastic components are stage clip 8.
Two clamping pieces 5 are symmetrical arranged, and each clamping piece 5 one side is formed with draw-in groove 51, and relative opposite side is formed with storage tank 52, and each clamping piece 5 is formed with perforation 53, this perforation 53 and storage tank 52 perforations.And the roof 55 of clamping piece 5 is formed with second inclined-plane 56 with sidewall 54 junctions that storage tank 52 is set.
Shown in Fig. 2,3,4, during assembly operation mechanism 3, with second elastic component is that stage clip 8 places in the blind hole 44 of operating parts 4, make stage clip 8 lower end abutment in blind hole 44 diapire and be sheathed on boss 441 outer ends, be placed on then between two dividing plates 63 of fixture 6, pass the interstitial hole 65 of fixture 6 upper ends and the long slot bore 45 of operating parts 4 by rivet 9 again, operating parts 4 can be connected in fixture 6 up or down, make stage clip 8 between this rivet 9 and operating parts 4 blind holes 44 diapires, and perseverance make operating parts 4 with respect to fixture 6 down under normal conditions.In other embodiments, also can up be provided with from the diapire of operating parts 4 blind hole or, this second elastic component can be extension spring, one end of this extension spring is connected in rivet, the other end is connected in the diapire of fixture 6, and so under normal conditions, extension spring also can perseverance make operating parts 4 with respect to fixture 6 down.
Be the storage tank 52 that torsion spring 7 places clamping piece 5 again with first elastic component, use then rivet (figure do not show) or similarly other connectors pass lateral opening 66, clamping piece 5 perforation 53 and the torsion springs 7 of fixture 6 upper end side, thereby clamping piece 5 is connected in fixture 6, and clamping piece storage tank 52 is towards operating parts 4, an end of torsion spring 7 is resisted against the wall portion of clamping piece 5 storage tanks 52 like this, the other end is resisted against the dividing plate of fixture 6, and between dividing plate two ribs 64, the location of the torsion spring 7 of being more convenient for like this.
Then operating mechanism 3 is assembled in base 2, operating mechanism 3 is positioned in the accommodation space 22 of base 2, pass the hole 67 of through hole 221 and fixture 6 side wall lower ends on base 2 accommodation spaces 22 sidewalls with other similar connectors such as rivet (figure do not show) or screws, thereby fixture 6 is fixedly connected on base 2, is about to whole operation mechanism 3 and is connected in base 2.
As shown in Figure 2, under the general state, bottom tube 1 one ends are sticked in the draw-in groove 51 of clamping piece 5, operating parts 4 tops 41 are between two clamping pieces 5, and with the sidewall 54 of two clamping pieces 5 form against, two clamping pieces 5 can not be rotated, thereby bottom tube 1 base 2 rotations relatively are about to bottom tube 1 and are locked in the state that a relative base 2 launches.At this moment, torsion spring 7 is squeezed.
As shown in Figure 4, when needing the locking of release the lock bottom tube 1 relative base 2, pulling process spare 4 (direction as shown by arrow B) up, stage clip 8 is subjected to the power of rivet 9 and compresses, when operating parts 4 up moves to certain distance, its top 41 break away to two clamping pieces, 5 sidewalls 54 against, thereby two clamping pieces 5 rotate (direction as shown by arrow C) under the restoring force effect of torsion spring 7, driving the also relative base 2 of base 2 simultaneously is center of circle rotation with pivoted hole 11, when rotating to certain angle, the part that bottom tube 1 is sticked in the draw-in groove 51 breaks away from draw-in groove 51 fully, thereby bottom tube 1 can be further rotated a position that folds with respect to base 2, as shown in Figure 5, and when clamping piece 5 rotates to certain angle, its second inclined-plane 56 is run into the sidewall of operating parts 4 lower parts 42 and is formed conflict, thereby clamping piece 5 can not further rotate along the arrow C direction again.At this moment, the operating parts 4 of letting go again, it is moved down under the restoring force effect of stage clip 8, when clamping piece 5 move down certain apart from the time, first inclined-plane 43 of operating parts 4 contact with the roof 55 of two clamping pieces 5 form against, can not move down again, thereby operating parts 4 and two clamping pieces 5 are in a metastable state.
Preferable, for easy to operate, can on operating parts 4, connect a ribbon (figure does not show), when needing up pulling process spare 4, directly draw ribbon to get final product.
As shown in Figure 6, when needs launch bottom tube 1 once again, down push away the base retracting mechanism, make bottom tube 1 rotation, when rotating to certain angle, bottom tube 1 one ends stretch in the clamping piece draw-in groove 51 once again, at this moment, in the process that bottom tube 1 is further rotated, thereby its tube wall contacts its application of force with the inwall of clamping piece draw-in groove 51, thereby promptly 1 pair of clamping piece 5 application of forces pressure of bottom tube makes clamping piece 5 rotations (as shown by arrow D).Clamping piece 5 can produce a power up to operating parts 4 in the process of rotation, because the setting of stage clip 8, operating parts 4 can up have certain displacement; Clamping piece 5 is further rotated, its roof 55 breaks away from the conflict with operating parts 4 first inclined-planes 43, bottom tube 1 is further being pressed clamping piece 5 rotations, operating parts 4 moves down under the effect of stage clip 8 restoring forces, until the top 41 of operating parts 4 once again with the sidewall 54 of clamping piece 5 against, thereby once again bottom tube 1 is locked in the position that a relative base 2 launches, as shown in Figure 5.
Although embodiment of the present utility model is open as above, but it is not limited only to listed utilization in specification and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
