And that completes plugging member 4 pulls out process；Two gunpowder drivers 2 can also be oppositely arranged on the two sides of 5 upper surface of pedestal, and two gunpowder drive
The output shaft or piston of dynamic device 2 are oppositely arranged, and two interlinking lever ends being connected on two sliding blocks 3 can then be driven to move toward one another,
Journey is inserted through to complete plugging member 4.
Further, it is preferable to which offer respectively on the upper surface of disk 501 can be to sliding block for corresponding two sliding blocks 3 in embodiment
3 grooves 502 limited, two grooves 502 to open up axis parallel with the axis of 2 output shaft of gunpowder driver, then can will
3 Corresponding matching of sliding block is embedded in groove 502, and sliding can be corresponded in groove 502, and can be by being preferably provided with groove 502
Length controls the sliding distance of sliding block 3；It is further preferred that the gunpowder driver 2 in preferred embodiment includes trigger, combustion
Burn room and accommodating gunpowder in a combustion chamber, the electric signal gunpowder that ignites received by trigger and is started to work, generate air-flow push it is defeated
Shaft or piston stretch out, and are slided accordingly by output shaft or piston driving sliding block 3, then drive the end of two connecting rods into
The opposite or opposite movement of row, to amplify and pass the stroke of sliding block 3；Further, it is preferable to embodiment
The driving force of middle gunpowder driver 2 can carry out preferably according to the actual situation, correspondingly, the length of corresponding component such as connecting rod, shell 6
Size and the size of pedestal 5 can be selected accordingly.
And specifically, it is preferable to can be counted by following formula in embodiment through the amplified stroke distances l of stroke amplifying mechanism 1
It calculates,
In formula, l is the stroke distances that plugging member 4 moves after stroke amplifying mechanism 1 is to stroke amplification；N is stroke amplification
The setting quantity of stroke amplifying unit, N >=1 in mechanism 1；θ1It is that the axis of first connecting rod 101 and sliding block 3 slide under original state
The angle in direction；X is the stroke of gunpowder driver 2, i.e. the sliding distance of sliding block 3 (provides the output shaft of gunpowder driver 2 herein
Outwardly directed value is positive, and the value inwardly retracted is negative)；Length of the L between 101 both ends through-hole of first connecting rod.
Through above-mentioned formula as can be seen that in the case where sliding block 3 slides same distance, in stroke amplifying mechanism 1
The quantity for the stroke amplifying unit being arranged in series increases, and the stroke distances of plugging member 4 increase, so can be by being preferably provided with stroke
The setting quantity of amplifying unit, the big stroke driving of Lai Shixian actuator；And it is certain in the setting quantity of stroke amplifying unit

On block 3；Further, two sliding blocks 3 match with the output shaft of corresponding gunpowder driver 2 connect respectively, can be right by gunpowder driver 2
Sliding block 3 should be driven to slide, the end movement of respective link is then driven, so that the angle between two connecting rods arranged in a crossed manner occurs
Variation, i.e. two connecting rods change away from the vertical range of pedestal 5 one end to pedestal 5, to realize the conversion of stroke, then lead to
It crosses and is sequentially connected in series multiple stroke amplifying units in scissors away from one end of pedestal 5 in first stroke amplifying unit, constitute stroke
Enlarger 1, and drive plugging member 4 to move by stroke amplifying mechanism 1, amplified by multistage of the stroke amplifying mechanism 1 to stroke,
The slide displacement of 5 top shoe 3 of pedestal can be converted to substantially displacement of the plugging member 4 on 5 direction of vertical feet, realize actuator
The big stroke of upper plugging member 4 controls.
It is further preferred that the original state of actuator is as shown in fig. 1 in preferred embodiment, at this point, two sliding blocks 3 away from
From minimum, two connecting rod angles in each stroke amplifying unit are also minimum, and the plug end end of plugging member 4 protrudes from pressure spiral shell 7
End face, to complete the control of external component in the component outside plug end Corresponding matching insertion, such as control of external isolating device
System；It is further preferred that the end face of spiral shell 7 is pressed in the corresponding fitting at this time of the positive stop end end face of plugging member 4, the limit of plugging member 4 is realized；
Further, after two gunpowder drivers 2, which receive electric signal, starts to work, the output shaft difference of two gunpowder drivers 2 is mutual
Away from stretching, that is, drive two sliding blocks 3 mutually away from movement, then two connecting rod angles in each stroke amplifying unit become larger, plug
For part 4 to the shortening of the distance between pedestal 5, i.e. the side of the plug end of drive plugging member 4 to close pedestal 5 is mobile, so that plugging
The end face at end does not protrude from the end face of pressure spiral shell 7, completes plug end from the withdrawal process in external component, and then external component can be into
The corresponding work of row.
Certainly, it also can be used as the original state of actuator when plugging member 4 is as shown in Figure 2, under this state, the driving of two gunpowder
Device 2 is relatively arranged on the edge of pedestal 5 respectively, and output shaft or piston are oppositely arranged；The distance of two sliding blocks 3 is most when initial
Greatly, may make the distance of two sliding blocks 3 to reduce by the relative extension of two gunpowder drivers, 2 output shaft, then drive plugging member 4 to
It is moved away from the direction of pedestal 5, i.e., the plug end on plugging member 4 is stretched out from the first through hole on pressure spiral shell 7, and then insertion is outer
In portion's component, that completes plug end is inserted through journey, to realize the control of respective process.
The big stroke actuator based on gunpowder driving of the utility model is driven by setting stroke amplifying mechanism 1, gunpowder
Device 2 and sliding block 3 so that one end of stroke amplifying mechanism 1 is correspondingly connected on gunpowder driver 2 by sliding block 3, and are driven by gunpowder
The stretching band movable slider 3 of dynamic 2 output shaft of device or piston slides, and then by the corresponding transmitting of the sliding stroke of sliding block 3 and is amplified to
On plugging member 4 on 1 other end of stroke amplifying mechanism, it is driven to complete plug/unplug stroke to realize the corresponding control of external component；
And the pressure spiral shell 7 by offering first through hole in the middle part of the setting of one end of pedestal 5 in shell 6, so that the plug end of plugging member 4
It can correspond in the first through hole, then plugging member 4 is guided by the first through hole and plugged along the axial-movement of the first through hole
The movement of part 4, prevent because in each stroke amplifying unit two connecting rods be driven power it is inconsistent due to lead to the plug end or so of plugging member 4
Deviate, influence the precision of Corresponding matching connection, by pressing the setting of spiral shell 7 and first through hole, can effectively realize the accurate of plugging member 4
Plug/unplug, promotes the precision and efficiency of plugging member work, and can be put by the quantity and each stroke for being preferably provided with stroke amplifying unit
The driving trip of gunpowder driver can be converted to the big stroke of plugging member 4, to realize actuation by the length of connecting rod in big unit
The big stroke fast driving of device, the time of response is fast, and the accuracy of control is high, effectively reduces actuator in big stroke, big drive
Quality and volume under power, expand the sphere of action of actuator, reduce the application convenience and economy of actuator, tool
There is preferable application and popularization value.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not
To limit the utility model, any modification made within the spirit and principle of the present invention, equivalent replacement and change
Into etc., it should be included within the scope of protection of this utility model.
