Detailed description of the invention
Below with reference to accompanying drawing, elaboration is further given to the utility model.
Refer to accompanying drawing 1 to accompanying drawing 4, this three-roller gate cored structure, it comprises: housing 1, the first electromagnet 2, second electromagnet 3, main shaft 10, ratchet 4, cam 12, the first locating part 5, second locating part 6, oil gear 7, spring assembly 8 and travel switch 9.
Refer to accompanying drawing 1, described ratchet 4 is installed on the through hole in the middle part of described housing 1, first electromagnet 2 and the second electromagnet 3 are installed on the housing 1 of ratchet 4 both sides respectively, and described oil gear 7 and spring assembly 8 are installed on the housing 1 outside the first electromagnet 2 and the second electromagnet 3 respectively; The first described locating part 5 is identical with the second locating part 6 structure, in L-type, ratchet 4 is supported in one end of first locating part 5, one end is connected to the first electromagnet 2 in addition, ratchet 4 is supported in one end of second locating part 6, and the other end is connected to the second electromagnet 3, and the middle part of the first locating part 5 and the second locating part 6 is installed on housing 1 respectively by a rotating shaft, described ratchet 4 and cam 12 are installed on same main shaft 10, and with main shaft 10 synchronous axial system; When detecting that user asks by signal, first electromagnet 2 action pulls the first locating part 5 to depart from ratchet 4, thus main shaft 10 is rotated, when main shaft 10 goes to 60 degree of central angles, main shaft 10 touches travel switch 9, travel switch 9 controls the first electromagnet 2 and resets, and drives the first locating part 5 action, makes it support ratchet 4, and, just relatively support cam 12 about the elastic tip of oil gear 7 and spring assembly 8, make main shaft 10 slowly turn over 60 degree of central angles, and stop.
Please accompanying drawings 1 and accompanying drawing 4 again, housing 1 is a sheet metal component, and the rectangular rib of housing 1 is wide, and its four corners are respectively provided with an installing hole, for housing 1 is fixedly installed in base.Housing central section is provided with a through hole, and this through hole is used for plug-in mounting main shaft 10, and main shaft 10 is set with ratchet 4 and cam 12 wherein, cam 12 is positioned at below ratchet 4, and ratchet 4 protrudes from housing 1 surface.
What the first electromagnet 2 was relative with the second electromagnet about 3 is installed on through hole both sides, and the first electromagnet 2 and the second electromagnet 3 can drive a movable axis separately, when electromagnet powers on, promotes movable axis, promotes locating part by movable axis.And the first locating part 5 is identical with the second locating part 6 structure, in L-type; For the first locating part 5, the bending flex point place of L-type first locating part 5 is installed on housing 1 by a rotating shaft is rotatable, one end of first locating part 5 is resisted against the emargintion place of ratchet 4, one end is connected to the movable axis that the first electromagnet drives in addition, when first electromagnet 2 powers on, the one end promoting the first locating part 5 departs from the breach of ratchet 4, thus makes main axis.And now, the second locating part 6 is in non-sour jujube and closes state, be restriction, the second locating part 6 rotates backward for preventing main shaft.
Refer to accompanying drawing 3, be provided with one stroke striker 11 between travel switch 9 and main shaft 10, cam 12 is supported in one end of the trip striker 11, and the other end, after moving right, can trigger travel switch 9.Travel switch 9 controls energising and the power-off of the first electromagnet 2 and the second electromagnet 3.
Further, refer to accompanying drawing 4, cam 12 is evenly three arc convex along axle center.Namely along axial line, outstanding three identical hearts are protruding, and whole circumference is divided into three parts, form three concave points and three raised points, raised points also claims summit simultaneously.The spring force of spring assembly 8 is greater than the pressure of oil gear 7 all the time.Therefore, the movable axis of and if only if spring assembly supports the concave point place of cam 12, when another summit supported by oil gear 7, rotating shaft just can be in stable state, when being in other states, oil gear 7 and spring assembly 8 acting in conjunction, make main shaft slowly enter stable state.
Please accompanying drawings 1 again, this ratchet 4 with 60 degree of central angles, is provided with arc notch at circumference place along axle center at equal intervals, and the first locating part 5 and the second locating part 6 are resisted against described arc notch.Main shaft 10 end is connected with a triroller gate bar, before main axis during 60 degree of central angles, manually restrictor bar is promoted by current personnel, rear 60 degree of central angles, jointly reset is completed by oil gear 7 and spring assembly 8, due to the cushioning effect of oil gear, restrictor bar rotates can be more steady, and clashing into sound also can be less.
Foregoing; be only preferred embodiment of the present utility model; not for limiting embodiment of the present utility model; those of ordinary skill in the art are according to central scope of the present utility model and spirit; can carry out corresponding flexible or amendment very easily, therefore protection domain of the present utility model should be as the criterion with the protection domain required by claims.
