Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1～3 show schematically show according to a kind of scalable plug of the lock pin of embodiment of the present utility model.As figure
Shown, this device includes lid 60, lower cover 10, lock pin 301, and insulate push rod 30, rocking bar 70, spring 80 and accordingly circuit mould
Block.
As shown in figs. 2 to 4, lower cover 10 corresponds to lock pin 301 and is provided with manhole appendix 108, and two manhole appendix 108 both sides are respectively
It is formed with guiding projection 101, guiding projection 101 is respectively equipped with conductive touch panel 20, conductive touch panel 20 extends guiding projection 101
And be provided with connecting hole (in figure is not noted), connecting hole can supply wiring, make this conductive touch panel 20 and plug other conducting channels or
Person's function circuit board electrically connects.Also it is formed with boss 109, boss 109 is provided with shrinkage pool 1091 between two manhole appendixs 108；Boss
Pore size between 109 with guiding projection 101 is consistent with manhole appendix, and it can stop and this for lock pin 301, and plays and lead
To effect, it is to avoid deviate manhole appendix 108 and action failure when lock pin 301 motion.
As shown in figures 2-3, lock pin 301 vertically bends and is formed with conducting block 302, and is close to insulate in conducting block 302 back side
Push rod 30 is fixedly installed on insulation push rod 30 two ends, makes the distance between two lock pins 301 and the distance between manhole appendix 108 phase
Deng.Insulation push rod 30 top is additionally provided with rotating disk 40, and insulation push rod 30 is provided with connecting hole, and rotating disk 40 one side is provided with perpendicular to rotating disk 40
One connecting post, connecting post neatly inserts the connecting hole of insulation push rod 30, so that connecting post ending vertical is thought in connecting post outer
Extend the spacing ring being formed greater diameter than connecting hole on insulation push rod 30, this spacing ring can limit rotating disk 40 and come off, thus,
Rotating disk 40 just can be articulated and connected in insulation push rod 30, and rotating disk 40 another side is then provided with polygonal grooves, with respect on rotating disk 40
Polygonal grooves, rocking bar 70 end is additionally provided with polygon projection.
As shown in figures 2-3, upper lid 60 is provided with screwed hole 601, and the screw rod of rocking bar 70 corresponds to described screwed hole 601 and sets
There is external screw thread, the screw rod of rocking bar 70 is installed on upper lid 60 by screw thread cooperation.
As shown in figures 2-3, it is additionally provided with guide post 50 between upper lid 60 and lower cover 10, described insulation push rod 30 is additionally provided with leads
Xiang Kong, guide post 50 passes through the pilot hole of insulation push rod 30.Spring 80 one end 80 is fixed at the shrinkage pool 1091 on boss 109
Interior, lock pin 301 inserts manhole appendix 108 and is connected to the insulation push rod 30 of lock pin 301 upper end and is placed on spring 80, by spring
80 are headed on and so that it is offseted with rocking bar 70 end face, and now spring 80 is in nature elongation state, and lock pin 301 end is just shunk in entering
108 inside edges portalled, specifically, lock pin 301 closes in shell.When needing plug insertion jack, can will insert
Manhole appendix 108 alignment receptacles of head, and so that plug joint face is fitted and receptacle face；Rotating rocker 70, then the spiral shell of rocking bar 70
Bar, due to the matching relationship with the screw thread of upper lid 60, also moves downward while rocking bar 70 own rotation, the polygon of its end
Due to coordinating with the polygonal grooves on rotating disk 40, thus, the rotation of rotating disk 40, rotating disk 40 are also stirred in the rotation of rocking bar 70 to projection
Down pushed away, moved downward, promote insulation push rod 30 make it overcome the power of spring 80 to move downward, simultaneously drive lock pin 301 to
Lower motion, lock pin 301 stretches out and inserts jack, thus reaching the purpose of plug insertion socket, moves downward in lock pin 301
At the limit, conducting block 302 is fitted with conductive touch panel 20, namely lock pin 301 is electrically connected with other circuit in shell, so that lock pin
Realize plug during the jack of 301 insertion sockets in the connection of power supply, reach the purpose that electrical equipment connects conduction with power supply.Guide post 50
Play the effect of guiding, make the stable movement of insulation push rod 30 accurate, it is to avoid lock pin 301 deviates manhole appendix 108.When needs are extracted
During plug, only need opposite direction pivots rocker 70, then rocking bar 70 drives motion upwards to drive insulation push rod 30 to move upwards, absolutely simultaneously
Edge push rod 30 is also promoted by spring 80 makes it move upwards；Now lock pin 301 toward shell contract and depart from jack realize plug with
The detached purpose of jack, spring 30 can head on insulation push rod 30 motion all the time and make its ends contact with rocking bar 70 all the time, keep away
Exempt from that gap occurs, affect kinematic accuracy.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality
New protection domain.
