Embodiment
The invention discloses a kind of docking facilities that connects fast, realized between connected element and firmly having connected fast.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skills, not making the every other embodiment who obtains under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1-Figure 3, Fig. 1 is a kind of quick connection docking facilities embodiment's of the present invention structural representation; Fig. 2 is the structural representation of guide sleeve in Fig. 1; Fig. 3 is the structural representation of guide sleeve in Fig. 1, snap ring a and snap ring b combination.
The present invention connects docking facilities fast, comprise attachment plug 1 and the counterpart that is connected with its grafting cooperation, described connection counterpart comprises shell 6 for holding miscellaneous part, is arranged on spring b 10, fore-set 5, snap ring b 4, spring c 11, steel ball 8, snap ring a 3, spring a 9 and the guide sleeve 2 in described shell 6 in order, on described guide sleeve 2, offer be severally circumferentially uniformly distributed, for holding the positioning hole 22 of steel ball 8, on described plug 1, offer the locating slot 1111 of circumferential distribution.In addition, the present invention connects fast docking facilities and also comprises for removing and installing the plug pushing piece 7 in described attachment plug.
Spring c 11 is set in outside fore-set 5 equally, be arranged between the card platform 51 and boss b 41 of fore-set 5 ends settings, relative movement compression or reduction by card platform 51 with boss b 41, in the time that boss b 41 is relatively static, one end of spring c 11 is equivalent to being stuck in boss b 41 places, Compress Spring c 11 when card platform 51 moves to boss b 41, in the time that the external force of Compress Spring c 11 disappears, the restoring force push card platform 51 of spring c 11, and then drive fore-set 5 to moving with respect to boss b 41 opposite directions.
Spring a 9 is set in outside guide sleeve 2, be arranged on guide sleeve 2 ends arrange boss c 21 and snap ring a 3 on boss a 31 between, relative movement compression or reduction by boss c 21 with boss a 31, in the time that boss c 21 is relatively static, one end of spring a 9 is equivalent to being stuck in boss c 21 places, Compress Spring a 9 when boss a 31 moves to boss c 21, in the time that the external force of spring a 9 disappears, if now boss c 21 is relatively static, the restoring force of spring a 9 promotes boss a 31, and then drives snap ring a 3 to moving with respect to boss c 21 opposite directions.
In the present invention's one specific embodiment, the elasticity coefficient size of above-mentioned spring a 9, spring b 10 and spring c 11 is Ka < Kb < Kc, by so reasonable setting, make plug 1 be relatively easy to insert guide sleeve 2, connect docking thereby complete fast.In the time using plug pushing piece 7 to insert to promote plug 1 in shell 6, also make fore-set 5 hand over easily to promote plug 1 to depart from a whole set of counterpart that connects, reach the object of quick-detachment band connected element.
In the present invention's one specific embodiment, described positioning hole 22 is beveled aperture, and restriction steel ball 8 does not drop out from positioning hole 22 in the time of free state.Further, the perpendicular distance L of described guide sleeve 2 outer walls and described snap ring b 4 inwalls is less than the diameter of steel ball 8, thereby further limit the freely position of activity of steel ball 8, steel ball 8 can not fallen in the cavity being surrounded as by snap ring a 3, snap ring b 4, card platform 51 and guide sleeve 2.
In the present invention's one specific embodiment, described snap ring a 3 and snap ring b 4 are preferably Split type structure, the convenient assembling that connects the each parts of counterpart.Certainly, also described snap ring a 3 and snap ring b 4 can be designed to the entirety of integrative-structure, can realize equally connection docking and the disassembling section of apparatus of the present invention.
In the present invention's one specific embodiment, described plug 1 is column structure, and its head has the ramp structure inside contracting gradually, and described fore-set 5 ends offer the restraining groove 52 that stretches into and locate for plug 1 head.Thereby attachment plug 1 is inserted into behind guide sleeve 2 inside, and plug 1 head stretches into restraining groove 52, be conducive to plug 1 and be inserted into fast in connection counterpart, reduce plug-in mounting difficulty.
Therefore, the present invention by attachment plug be connected counterpart and connect parts to be connected, connect by additional means without borrowing, convenient to operation, can realize fast the connection to two parts.That the present invention also has is simple in structure, it is stronger to bear load capacity, and the durable feature such as reliable, is conducive to Reusability.In addition reasonable in design of the present invention, by taking-up instrument simple in structure can by plug be connected counterpart and separate, thereby reach the object of quick-detachment band connected element.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to these embodiments' multiple modification, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
