Between 131 and the tail end of pull rod 15, drawstring is passed through from spacing ring, is then limited ring guide and limit, and then drawstring is around rolling
Wheel 131, realization commutate again.The setting of reverse wheel group 13 can be prevented when drawstring is inclined by pulling at spacing ring because of drawstring with limiting
The side sidewall friction of position ring and cause drawstring to pull the problem of difficult, drawstring can change direction after reverse wheel group 13, and
It is rolling friction between drawstring and reverse wheel group 13 so that drawstring is from lighter, laborsaving, Yong Huke during any direction bracing wire
To pull drawstring from any direction so that bracing wire operation is more convenient, solves tradition and is only capable of from rear portion vertical pulling line, and from side
The problem of then being caused high effort for during bracing wire or even breaking drawstring.
In order to unlock the problem of signal wire is directly thrown away, causes subsequent operation to bother by existing electronic lock from rear portion,
Housing 1 is equipped with extends to connector 14 outside 1 rear end of housing out of housing 1, and connector 14 is hollow tubular structure, signal
Passed through after harness boundling from connector 14, all harness can be subjected to arrangement arrangement, only be needed connector in subsequent operation
Inserting for 14 pairs to operate.
In use, especially in charging process, charging gun is inserted into charging socket to the electric vehicle of the utility model
Afterwards, the electromagnet 2 of controller control electronic lock is powered, and band dynamic iron core 32 acts, and iron core 32 moves lock by bulb 6 and connection tape
Pin 31 acts, and due to the effect of bulb 6, the deflection of iron core 32 is not transferred to lock pin 31, and the deflection of lock pin 31 then passes through
Guide sleeve is corrected so that lock pin 31 can be accurately inserted into the lockhole of charging gun, locking is realized, at this time on lock pin 31
5 position of magnetic induction sensor that magnet 7 is set close to lower part, magnetic induction sensor 5 detect signal in place and will signals in place
Controller is fed back to, to notify user to know in time, similarly, in unlock, the magnetic induction sensor 5 on top also can will in place
Signal feeds back to controller；When the electronic lock failure after locking or power-off need emergency release, user can pull drawing manually
Rope 12, drawstring 12 pulls shifting part 9 to act and promote block machine 8 to act, and then retracts with pendulum lock pin 31, unclamps and draws after the completion of unlock
Rope 12, resetting spring 10 can drive drawstring 12 to be resetted；When pulling drawstring 12, due to the presence of reverse wheel group 13, use
Family can very easily be pulled from any direction.
In other embodiments：Magnet also can be replaced electromagnet to be not limited to permanent magnet；Also pull rod can be not provided with, this
When drawstring directly through housing, and stretch and sealing structure be set between housing, at this time reverse wheel group be set directly at drawstring from
The outgoing line position being pierced by housing is nearby；Reverse wheel group is that may be provided at the right side of drawstring outlet, may also be arranged on a left side
Side, as long as the position of reverse wheel group is located at the side of the remote lock pin of the reversal point position of drawstring；Spacing ring can be also not provided with,
Reversal point position is located at tie rod end and drawstring contact position at this time；Shifting part is by pull rod and casing with the guiding movement in housing
Mode also can be replaced the mode that shifting part carries out guiding movement cooperation with the guide rail set in inner walls, at this time without setting
