Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.To it is pointed out that described in the present embodiment multiple refers to two or more.
As shown in Figures 2 and 3, the one lock clutch of the utility model preferred embodiment, it comprises outer switch block 1, clutch ring 2, interior switch block 3 and elasticity on-of pin 4, outer switch block 1 radial direction is provided with outer switch block and drives boss 11 and clutch draw-in groove 12, the radial direction of clutch ring 2 is provided with on-of pin jack 21, wherein, the back-moving spring 42 that elasticity on-of pin 4 comprises clutch bayonet lock 41 and is sleeved on this clutch bayonet lock 41, driving mechanism can be adopted to drive elasticity on-of pin 4, elasticity on-of pin 4 is made to insert on-of pin jack 21 and clutch draw-in groove 12 successively slidably, interior switch block 3 radial direction is provided with interior switch block and drives boss 31, the first chimb collar 22 and the second chimb collar 23 that the two ends of clutch ring 2 are respectively equipped with, the first chimb collar 22 is provided with outer avoiding hollow groove 24, the second chimb collar 23 be provided with to drive with interior switch block boss 31 match in stopper slot 25, outer switch block 1 and interior switch block 3 insert in the centre bore of clutch ring 2 from the two end portions of clutch ring 2 respectively, and outer switch block drives boss 11 to be positioned at outer avoiding hollow groove 24, interior switch block drives boss 31 to be positioned at stopper slot 25.
The first chimb collar 22 and the second chimb collar 23 has been set up at the two ends of clutch ring 2, in the centre bore of outer switch block 1 and interior switch block 3 partial insertion clutch ring 2, form certain encirclement structure, as shown in Figure 3 and Figure 6, when door lock is in abnormal operational conditions, the encirclement respective outer side edges upper cover that the chimb collar of clutch ring 2 is formed and lower cover can externally switch block 1 and interior switch block 3 be formed and clamp down on power, make clutch ring difficult drop-off.
Clamp down on power in order to what strengthen the external switch block of clutch ring 1 and interior switch block 3 further, preferably, the first chimb collar 22 carries out clamping rotatably with outer switch block 1, and the second chimb collar 23 carries out clamping rotatably with interior switch block 3.Particularly, shown in composition graphs 2 and Fig. 4, the inner side of the first chimb collar 22 is provided with the first annular slot 221, and the outer edge of outer switch block 1 is provided with outer switch block bulge loop 13, outer switch block bulge loop 13 and the first annular slot 221 clamping, make outer switch block 1 can rotate relative to the first chimb collar 221.Particularly, the inner side of the second chimb collar 23 is provided with the second annular slot 231, and the outer edge of interior switch block 3 is provided with interior switch block bulge loop 32, and interior switch block bulge loop 32 and the second annular slot 231 clamping, make interior switch block 3 can rotate relative to the second chimb collar 23.Outer switch block drives boss 11 to be located on outer switch block bulge loop 13, and interior switch block drives boss 31 to be located on interior switch block bulge loop 32, to make structure rationalization.
The needs of R.H.flapped door and L.H.flapped door can be met in order to realize a lock body simultaneously, the first chimb collar 22 of the present embodiment is also provided with the outer stopper slot 222 driving boss 31 to match with interior switch block, as shown in Fig. 2, Fig. 4 and Fig. 5, this outer stopper slot 222 is relative with interior stopper slot position; The second chimb collar 23 is also provided with interior avoiding hollow groove 26, and this interior avoiding hollow groove 26 is relative with outer avoiding hollow groove 24 position; Clutch draw-in groove 12 comprises the first clutch draw-in groove 121 and the second clutch draw-in groove 122, first clutch draw-in groove 121 and the second clutch draw-in groove 122 in addition switch block drive the center line of boss 11 to be symmetrical arranged, the invariant position of clutch ring can be kept thus, outer switch block and interior switch block transposition can be realized left and right enabling.
As shown in Figure 6, the utility model additionally provides a kind of double quick door lock, it comprises upper cover 5, lower cover 6, door Internal handle, door outer handle, dead bolt push rod, dead bolt and above-mentioned lock clutch, this lock clutch is between upper cover 5 and lower cover 6, outer switch block 1 and interior switch block 3 are respectively equipped with handle drive hole, and handle drive hole is coaxial with the centre bore of clutch ring 2.
The course of work of Lock for two-wind door of the present utility model, for R.H.flapped door:
When elasticity on-of pin 4 and driving mechanism depart from, clutch bayonet lock 41 stretches out on-of pin jack 21 under the elastic force effect of back-moving spring 42, the idle running of outer switch block 1 can be realized, if outdoors, the counter-rotating of outer switch block 1 is driven by door handle, when outer switch block boss 13 contacts with the shelves limit of the first chimb collar 22, clutch ring is closed the door and is driven boss 28 can move together and withstand dead bolt push rod to moving outdoors, dead bolt push rod can be driven to moving outdoors, dead bolt to be inserted in lockhole, thus realize locking outdoors;
When inputting password or fingerprint by lock panel, during to connect driving mechanism, the elastic force that clutch bayonet lock 41 is overcome back-moving spring 42 by driving mechanism pushes on-of pin jack 21 and clutch bayonet lock 41, the afterbody of clutch bayonet lock 41 is blocked in the first clutch draw-in groove 121 thus realizes the interlock of outer switch block and clutch ring, now forward turning cell outer door handle, when outer switch block 1 and clutch ring 2 can be driven synchronously to operate clockwise, clutch ring opens the door to drive boss 27 to move together and withstand dead bolt push rod and move in door dead bolt is extracted from lockhole, thus realization opens door lock outdoors;
When indoor revolving door handle, interior switch block 3 and clutch ring 2 synchronous axial system can be driven, thus realize locking in door or unblanking.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
