(5) specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Illustrated a kind of lock electricity consumption type slide plate push-and-pull travel mechanism comprises housing 6, is fixed on the motor 7 on the housing and is installed in slide plate 5 on the housing slippingly; Pivot is equipped with power transmission shaft 10 on the housing 6, is connected transmission by gear train 9 between power transmission shaft 10 and the motor 7; Be set with on the power transmission shaft 10 can be axially movable slide block 13 and can promote the spring 12 that slide block 13 moves, spring 12 is arranged in the vacancy of slide block 13, spring 12 two ends are radially stretched in the axial groove of slide block 13 (in Fig. 1, spring 12 two ends and axial groove just in time are positioned at power transmission shaft 10 dead asterns, and be not shown.), spring 12 can only be moved axially can not rotate; Half place of the length of power transmission shaft 10 is fixed with cotter pilotage 11, and cotter pilotage 11 also is arranged in the vacancy of slide block 13, and cotter pilotage 11 two ends are radially stretched and established and can screw between the two adjacent rings of spring 12, and spring 12 is moved around on power transmission shaft 10 with positive and negative the transferring of cotter pilotage 11; One shifting block that can handle slide plate is arranged on the slide block 13, on the slide plate 5 therewith the shifting block corresponding position have a hole, shifting block stretches in this hole, moves and make slide block 13 drive slide plates 5.Slide plate 5 both sides are provided with the fixed leg 1 that can be fixed on the body, are equipped with on two guide strips, 4, two guide strips 4 by spacer 3 and screw 2 on the fixed leg 1 and are respectively equipped with gathering sill, and the projection on the slide plate 5 stretches in the gathering sill.Also being provided with on the slide block 13 can be by the shifting block 14 of other mechanism operating, and this shifting block 14 and the shifting block that can handle slide plate are separately positioned on the both sides of slide block 13.Be covered with cover plate 8 on the housing 6.
Design feature:
1, with spring 12 as actuated element, it is a kind of type of belt drive of flexibility.
2, spring 12 is again the parts of an energy storage, when slide plate 5 is obstructed because of external cause moves, that is to say when slide block 13 can't be mobile, still can shift to the other end to spring 12 by cotter pilotage 11 with the power transmission shaft 10 that motor 7 rotates.The spring 12 of this moment is tending towards by complete compressive state---the energy storage state, and in a single day slide plate 5 can move, and spring 12 will move into place slide block 13.This function has crucial practical value to the door lock series products, and maloperation when opening the door is being held up hand handle too at full tilt and handle off normal, the action of slide plate 5 are obstructed, and causes the failure of opening the door first, but this moment, spring 12 became the energy storage state.As long as allow handle automatically reset, door lock door opening state, opening the door once more will be successful.This point is incomparable for the push-and-pull travel mechanism that is power at present with the electromagnet.
3, can be arranged to channel status (being normally open) to door lock.The position that slide plate 5 pushes away or draws has been handled in the forward and reverse of motor 7 in this motor type slide plate push-and-pull travel mechanism, is controlling closing or opening of door lock.As long as do not give motor reversed polarity power supply instruction in software, slide plate 5 will keep the position of " drawing ", and door lock just is opening (channel status), even under the environment that vibrates or impact, also can guarantee the reliability of duty.This is just difficult realization of mechanism of power with the electromagnet, switches on regard to adhesive because of electromagnet, just becomes opening, as long as outage just becomes closed condition at once.The poor-performing of electromagnet anti-vibration and impact when adhesive in addition.
4, the compact conformation of this mechanism, volume is little, good rigidly, easy for installation.Link to each other with the body of door lock by fixed leg 1.Spacer 3 on the fixed leg 1 and guide strip 4 constitute the pattern of framework again, have enough non-yielding props and moving of slide plate 5, have strengthened the firmness of door lock.
