Five, embodiment
Embodiment 1
The present invention includes as Fig. 1: insurance carriage 1, loam cake 2, drop hammer 3, housing 4, push rod 5, the pallet 6 that drops hammer, carry out bar 7, base 8, spring 9 and rotary hook 10 and form.Housing 4 bottoms are symmetrically arranged with two some through holes 11, housing 4 upper inside wall are hinged with insurance carriage 1, pressure pin on the insurance carriage 1 places outside the housing 4, pressure pin is provided with knob, drop hammer and 3 place push rod 5 tops, push rod 5 passes the pallet 6 that drops hammer fixedlys connected with base 8, pallet 6 belows of dropping hammer are provided with and carry out bar 7, carrying out bar 7 two ends places respectively in the through hole 11, carry out bar 7 and be provided with dog hole, rotary hook 10 and push rod 5 lower hinge, the gib head end to the gravitational torque of pin joint greater than the gravitational torque of hook tail end to same pin joint, the gib head on the rotary hook 10 with carry out bar 7 on dog hole corresponding, carry out bar 7 belows and be provided with spring 9, spring 9 one ends are fixed on housing 4 inwalls, and the other end is fixedlyed connected with execution bar 7.Position and the adjustable number of carrying out the bar upper aperture save required execution stroke;
Push rod 5 of the present invention is vertically fixed to the center of base 8, and the pallet 6 that drops hammer can freely slide up and down on push rod 5.Insurance carriage 1 is articulated on housing 4 inwalls, and the pressure pin of insurance carriage 1 reaches housing 4 outsides, and insurance carriage 1 can swing up and down in housing 4 inside, and its limes superiors position is the level of state, and the smallest limit position is the vertical state.The external part of upper and lower promotion carriage 1 can be realized the conversion between these two kinds of location statuss, and can guarantee that the state of selecting is maintained.When insurance carriage 1 when being in horizontal level, 3 the bottom of dropping hammer that is in this carriage 1 center just in time steadily contacts with the upper surface of push rod 5, and this moment is if insurance carriage 1 breaks away to lower swing to drop hammer after 5, drops hammer 5 can staticly rest on the upper surface of push rod 5.Drop hammer 3 and the surface of contact of insurance between the carriage 1 match, can make drops hammer 3 realizes location automatically on carriage 1.
Rotary hook 10 is connected push rod 5 bottoms by a hinge axis, relies on its dead-load moment to rest on clockwise extreme position during free state.If the dog hole on the execution bar 7 is over against gib head, then can realize rising to the bait automatically, and can realize that carrying out bar 7 with steel closely contacts by the permanent magnet 12 that is fixed on the hook, thereby guarantee to be unlikely under the rotary hook 10 pallet 6 deadweight effects of dropping hammer at an upper portion thereof opposite spin rotary hook 10 and execution bar 7 are thrown off automatically.One end of spring 9 is fixed on housing 4 inwalls, the other end be connected to be positioned at carry out bar 7 bottoms with carry out on the spring carrier arm that bar 7 is made of one, whole execution bar 7 levels are through housing central authorities and can be free to slide at the through hole 11 that is arranged in two relative positions on housing 4 walls.
The center, upper surface of push rod 5 of the present invention is provided with a smooth normal cone of little tapering that raises up, and can match with the spill conicle that the same position, 3 bottoms of dropping hammer is provided with same shape.
During use, this trigger is fixed to by on warning target or the object, guarantees that it is in upright plummet state; Open loam cake 2, mention the pallet 6 that drops hammer, determine to carry out the impulse stroke of bar 7 and rotary hook 10 is hooked on the square hole of carrying out bar 7 correspondence courses, put down the pallet 6 that drops hammer; The carriage 1 that will drop hammer is adjusted to horizontal level and is made it be in locking state (promptly being in locking state behind the release button); To drop hammer 3 is put on the carriage 1, and assurance well contacts with carriage; Connect load; Cover loam cake 2; The carriage 1 that drops hammer is rotated down plumb position, and this moment, this trigger just was on the alert.If in the time of need moving this trigger, it is in a safe condition as long as the carriage 1 that drops hammer is rotated to horizontal level.
Housing 4 can be made the side installing type as required.
The course of work
When motion (vibration) appears in the object (object or target) of monitored or warning, this actuator under being on the alert will be with being moved by the warning object, be in dropping hammer of unstable equilibrium state 3 promptly can fall on push rod top, impact drop hammer pallet 6 make rotary hook 10 rotation and with carry out bar 7 and throw off, carry out bar 7 and will realize required trigger action at its through hole 11 generation high-speed motions under the spring action that is positioned at below it.
Embodiment 2
Be symmetrically arranged with through hole 11 on the housing 4 of the present invention, housing 4 upper inside wall are hinged with insurance carriage 1, pressure pin on the insurance carriage 1 places outside the housing 4, pressure pin is provided with knob, drop hammer and 3 place push rod 5 tops, push rod 5 passes the pallet 6 that drops hammer fixedlys connected with base 8, pallet 6 belows of dropping hammer are provided with and carry out bar 7, carrying out bar 7 two ends puts respectively in the through hole 11, carry out to be installed with on the bar 7 and stir crossbeam 12, be positioned on the inwall of carrying out bar 7 upper shell 4 and be hinged with rocking bar 10, the shift fork at rocking bar 10 both ends is slidingly connected with the end of stirring crossbeam 12 respectively, near stir through hole 11 on crossbeam 12 1 side bodies above or below be provided with permanent magnet.
Carry out bar 7 and be provided with axle 13 with rocking bar 10 hinge places, axle 13 at least one ends place housing 4 outsides, on axle 13, can obtain required angular displacement and certain moment, also fixed the shift fork of a disymmetry simultaneously in the rotating shaft of these rocking bar both sides, this shift fork can stir that to carry out bar mobile its through hole 11 in by being fixed to the horizontal curvature crossbeam of carrying out on the bar 7.For making rocking bar 10 under the pallet 6 deadweight effects of dropping hammer, be unlikely to rotate, on execution bar 7, fix a permanent magnet 9, thereby make execution bar 7 this magnet when initial position keep attracting state to make execution bar 7 remain on its initial threshold position with housing wall.
During use, this trigger is fixed to by on warning target or the object, guarantees that it is in upright plummet state; Open loam cake 2, mention the pallet 6 that drops hammer, move to initial position (limit on the left position as shown in Figure 5) carrying out bar 7, owing to carry out the effect of magnet on the bar 7, carry out bar and will be firmly held in this position this moment; Put down the pallet 6 that drops hammer; The carriage 1 that will drop hammer is adjusted to horizontal level and is made it be in locking state (promptly being in locking state behind the release button); To drop hammer 3 is put on the carriage 1, and assurance well contacts with carriage; On execution bar 7, connect load; Cover loam cake 2; The carriage 1 that drops hammer is rotated down plumb position, and this moment, this trigger just was on the alert.If in the time of need moving this trigger, it is in a safe condition as long as the carriage 1 that drops hammer is rotated to horizontal level.
The course of work
When motion (vibration) appears in the object (object or target) of monitored or warning, actuator under being on the alert will be with being moved by the warning object, be in dropping hammer of unstable equilibrium state 3 promptly can fall on push rod top, impact drop hammer pallet 6 make this pallet on push rod 5 to lower slider, promote to rotate in the axis hole of rocking bar 10 drive axles 13 on housing 4, realized angular displacement output thus; Simultaneously, the shift fork that is positioned at rocking bar 10 lower ends is stirred the crooked crossbeam of carrying out on the bar 7 12, drives to carry out in the through hole 11 of bar 7 on housing 4 and slides, and has realized required trigger action.
