Detailed description of the invention
And the application is described in detail below with reference to the accompanying drawings in conjunction with the embodiments.Following embodiment only have expressed the preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the application's the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the application's design, any improvement of making on basis of the present invention and change are all within protection scope of the present invention.
Electromagnetic ground lock in the present invention, comprise housing, pedestal, a lock body chamber and a wire connection cavity is formed in the both sides of pedestal, in wire connection cavity, wiring terminal is installed, electric-magnetic lock mechanism is installed in lock body chamber, some microswitches 5 and grounding base, what be provided with the insertion of confession earth rod in described grounding base patches passage, electric-magnetic lock mechanism is arranged on the side of grounding base, the multiple hoodles 2 with the fit depressions of ground wire are provided with in lock body, wherein hoodle realizes spacing by electric-magnetic lock mechanism, also be provided with in lock body chamber and touch plug 6 and elastic component 3, some microswitches to be fixed on side by side in lock body chamber by holder and to be arranged on plug both sides, microswitch and constant with microswitch parallel distance is triggered by plug sidewall, plug is led by guide finger 4 and is resetted by elastic component.
Further, electric-magnetic lock mechanism is also provided with the electromagnetic lock ground stud for ground connection, is illustrated in figure 4 this ground connection electromagnetic lock earth wire pile organigram, ground wire 1, grounding base, adaptor 8 and wing nut 9; Wherein grounding base is provided with external thread sleeve 7 and forms an entirety with grounding base, adaptor 8 is provided with internal thread, coordinate with the external thread sleeve 7 of grounding base, earth wire pile is provided with ground wire 1 patchhole, the end face that ground wire 1 inserts backward step and earth wire pile external thread sleeve 7 fits, to be provided with externally threaded wing nut 9 screw-in to establish in female adaptor 8, the step pushing down ground wire 1 makes it closely be connected with earth wire pile, reaches the object of ground connection.Meanwhile, outside moisture and impurity is stoped to enter lock body structure by screw-threaded engagement.
Further; on pedestal; be provided with the protecgulum respectively as the shell of lock body chamber and wire connection cavity and bonnet, wherein bonnet is interlocked by draw-in groove and protecgulum, in use; open bonnet and implement patching operations with butted line chamber; now without the need to taking protecgulum apart, blocking mechanism part is protected, and when normally using; because the fastening effect of draw-in groove cannot to be uncapped operation to protecgulum when not taking bonnet apart, thus effectively prevent operating personnel from tearing protecgulum open by mistake and impacting latch portion.
Working method 1
In the use procedure of electric-magnetic lock mechanism, press latch switch by operator, the solenoid in blocking mechanism is energized, cause dynamic iron core action to remove spacing to hoodle, make hoodle mobile to be opened by the entrance of electromagnetic lock backward, now can carry out the insert action of ground wire.Operator inserts ground wire, screws the external thread sleeve of ground wire, and ground wire contacts with earth wire pile and forms path, promote to touch plug simultaneously, microswitch, externally mechanism's outgoing signal are triggered in plug side, complete after update until ground wire, operator unclamps latch switch, make the solenoid power-off in blocking mechanism, cause dynamic iron core to decline under the action of the spring, carry out spacing to hoodle, make ground wire locking in lock body, thus make the blocking function of electromagnetic lock.Corresponding with it, the method for getting ground wire is identical with aforesaid operations method.
When ground wire takes out from lock body, the effect that plug is directed through spring by guide finger resets, now plug resets and blocks ground wire entrance, protective action is played to ground wire entrance, stop outside moisture and impurity to enter lock body structure, thus achieve electromagnetic lock when using out of doors, no matter be in ground connection duty or under disconnecting armed state, all realize closing to ground wire entrance, prevent the function that foreign matter enters.
Further, because microswitch is arranged on plug both sides, when ground wire insertion promotion plug moves upward, plug sidewall triggers microswitch and constant with microswitch parallel distance, microswitch triggering and conducting stroke increases,, there is not overvoltage phenomenon, effectively extend the application life of microswitch in stable enhancing.
Working method 2
As shown in Figure 5, during installation, grounding base 10 is welded on on-the-spot earth conductor, then, adapter 13 is screwed on the grounding copper nut 12 on grounding base 10, until adapter end flat 22 develops with the plane 12 of grounding copper nut root, thus complete the in-site installation of earth wire pile, as shown in Figure 7, during use, after on-the-spot ground wire 1 passes through to adapter ground wire jack 11, together with wing nut 9 is screwed to the external screw thread 21 on adapter, and ground wire is fixed, ground wire 1 inserts the ground wire testing agency 14 in lock body, detection signal is passed by wiring terminal 15 by ground wire testing agency 14, thus complete the mounting of grounding wire.
When repeatedly releasably the end of a thread time, cause ground wire 1 to install loosely because wing nut 9 rubs for more than 21 time with the external screw thread on adapter, now, adapter 2 can be backed out, again change a new adapter and just can solve ground wire loosening problem is installed.
