Description
Technical field
The utility model belongs to field of lockset, relates to plug latch, especially a kind of GB three phase mains plug latch.
Background technology
Attaching plug is the media that power consumption equipment connects power supply, no matter is household electrical appliance or the various device in the commercial production in the daily life, all need connect power supply through attaching plug.When power consumption equipment does not use or to equipment, keeping in repair, pull up attaching plug, deenergization usually, attaching plug is placed near the power supply usually, exists the potential safety hazard that mistake connects thus; Particularly in commercial production, might cause very big loss even danger.Therefore, connect for fear of mistake, and play warning function, the measure of taking at present is that attaching plug is placed in the lock box with the attaching plug size match, and closed lock box also adopts padlock that lock box is locked.This mode need be put into lock box with attaching plug integral body, and the lock box volume is bigger, and profile is common, and it is limited to play warning function, and use neither be very convenient.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of GB three phase mains plug latch is provided, and this plug latch is convenient to use, good warning effect.
The utility model solves its technical problem and realizes through following technical scheme:
A kind of GB three phase mains plug latch; Comprise lock box, screw rod, screw, crushing block, laterally be shaped on the slot of three metal legs of plug-in mounting attaching plug at the positive middle part of lock box, in lock box, install a screw; This screw is vertically installed a screw rod in the engagement of lock box internal thread; A crushing block is adorned on the inner end top of this screw rod in lock box, and the front end of this crushing block is processed the wedge shape termination of mirror image symmetry, and this crushing block vertically slides in the made vertical guide groove in both sides in lock box; On the pairing lock box in the wedge shape termination of crushing block, be shaped on the wedge shape guide groove; Medium position is vertically installed a returning spring between the bottom face of the lower surface, wedge shape termination of crushing block and wedge shape guide groove; Two slots that connect the electric metal pin of the gap corresponding power plug between the made wedge shape guide groove both sides end face of the wedge shape termination two side ends face of crushing block and lock box are shaped on a vertical connecting to neutral conduit on the crushing block of the connecting to neutral metal leg slot of corresponding power plug.
And said screw rod installs one in the outer end of lock box and manually revolves handle.
And; Side manually revolving the lock box side at place is hinged with buckle closure through hinge; Movable end at buckle closure is shaped on lock hook, on the lock box of another side that cuts with scissors the dress buckle closure, is shaped on lock ring, and lock hook overlaps and encapsulates with lock ring and manually revolves handle when the buckle closure returning buckle is contained on the lock box.
Advantage of the utility model and beneficial effect are:
1, this plug latch adopts the mode of the plug metal leg directly being inserted the lock body lock, and is convenient to use, advantages of small volume.
2, this plug latch adopts and manually revolves the extruding force locking plug metal leg that produces engagement screws, can not scratch metal leg, adopts spring to reply the mode release, and is simple and practical, rational in infrastructure, design science.
3, this plug latch is hinged with buckle closure on lock box, but this buckle closure rotation and spiral-lock manually revolve and adopt the padlock locking, have the professional effect of plug latch, warning function is strong.

Embodiment
Below in conjunction with accompanying drawing, through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection range of the utility model with this.
A kind of GB three phase mains plug latch; Comprise lock box 6, buckle closure 2, screw rod 9, screw 8, crushing block 12; Laterally be shaped on the slot of 7 three metal legs of plug-in mounting attaching plug at the positive middle part of lock box; Side at the lock box upper side is hinged with buckle closure through hinge 3, is shaped on lock hook 1 at the movable end of buckle closure; On the lock box of another side that cuts with scissors the dress buckle closure, be shaped on lock ring 5, lock hook overlaps with lock ring and can adopt padlock that lock hook is locked on the lock ring when the buckle closure returning buckle is contained on the lock box.In the lock box of side, buckle closure place, install a screw; This screw is vertically installed a screw rod in the engagement of lock box internal thread; The outer end of this screw rod on lock box installs one and manually revolves 4; A crushing block is adorned on the inner end top of this screw rod in lock box, and the front end of this crushing block is processed the wedge shape termination of mirror image symmetry, and this crushing block is vertically slip in the made vertical guide groove 11 in both sides in lock box; On the pairing lock box in the wedge shape termination of crushing block, be shaped on wedge shape guide groove 14; Medium position is vertically installed a returning spring 13 between the bottom face of the lower surface, wedge shape termination of crushing block and wedge shape guide groove; Two slots that connect the electric metal pin of the gap corresponding power plug between the made wedge shape guide groove both sides end face of the wedge shape termination two side ends face of crushing block and lock box; On the crushing block of the connecting to neutral metal leg slot of corresponding power plug, be shaped on a vertical connecting to neutral conduit 10; This connecting to neutral conduit is vertically longer, to reserve the space of connecting to neutral metal leg length travel.
In the present embodiment, lock box adopts plastic production.
The utility model is exclusively used in GB three phase mains plug.
The operation principle of the utility model is:
Extract and insert: twisting is manually revolved screw rod is retreated; The crushing block of dress is pushed up in wedge shape termination that increases crushing block under the thrust of returning spring and the gap between the wedge shape guide groove in the screw rod inner end, at this moment attaching plug connect the electric metal pin, the connecting to neutral metal leg all can freely insert and extract.
Locking: twisting is manually revolved screw rod is advanced; The screw rod inner end promotes crushing block to the displacement of wedge shape guide groove direction; The wedge shape termination of crushing block and the distance between the wedge shape guide groove diminish, and make the attaching plug of insertion connect the electric metal pin and are squeezed in therebetween and fix, and realize connecing the locking of electric metal pin.Because the connecting to neutral conduit is vertically longer, so the connecting to neutral metal leg has enough upper and lower displacement distances, avoids docking the obstruction that the locking of electric metal pin is caused.
Lock: handle is manually revolved in buckle closure upset encapsulation, padlock is belonged on the lock ring, the realization stranger can not operate manually revolves handle.
