Description
Technical field
The utility model belongs to field of lockset, relates to plug latch, especially a kind of Europe superscript two-phase power supply plug latch.
Background technology
Attaching plug is the medium that power consumption equipment connects power supply, no matter is household electrical appliance in the daily life or the various device in the industrial production, all needs to connect power supply by attaching plug.When keeping in repair when power consumption equipment does not use or to equipment, usually pull up attaching plug, deenergization, attaching plug is placed near the power supply usually, exists thus the potential safety hazard that mistake connects; Particularly in industrial production, might cause very large loss even danger.Therefore, connect for fear of mistake, and play warning function, Adopts measure is that attaching plug is placed in the lock box that mates with the attaching plug size at present, and closed lock box also adopts padlock that lock box is locked.This mode need to be put into lock box with attaching plug integral body, and the lock box volume is larger, 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 this utility model is to overcome the deficiencies in the prior art, and a kind of Europe superscript two-phase power supply plug latch is provided, and this plug latch is convenient to use, good warning effect.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of Europe superscript two-phase power supply plug latch, comprise lock box, screw rod, screw, crushing block, fixing guide groove, laterally be shaped with the slot of two metal legs of plug-in mounting attaching plug at the positive middle part of lock box, in lock box, be fixedly mounted with a screw, this screw is vertically installed a screw rod in the engagement of lock box internal thread, the inner end top of this screw rod in lock box fills a crushing block, and this crushing block vertically slides in the made fixedly guide groove in lock box; Crushing block with fixedly between the guide groove the made slot of corresponding lock box jointly be shaped with a squeezing groove, the crushing block of squeezing groove both sides and fixedly between the guide groove mirror image symmetry returning spring vertically is installed respectively.
And the outer end of described screw rod on lock box is fixedly mounted with one and manually revolves handle.
And, be hinged with buckle closure at a side that manually revolves the lock box side at place by hinge, movable end at buckle closure is shaped with lock hook, and the lock box that fills another side of buckle closure in hinge is shaped with 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 present utility model and beneficial effect are:
1, this plug latch adopts the plug metal leg is directly inserted the mode that locks in the lock body, and convenient to use, volume is small and exquisite.
2, this plug latch adopts and manually revolves the extruding force locking plug metal leg that engagement screws is produced, and 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 at 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
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of Europe superscript two-phase power supply plug latch, comprise lock box 5, buckle closure 2, screw rod 9, screw 8, crushing block 10, fixing guide groove 13, laterally be shaped with the slot of 7 two 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 by hinge 3, is shaped with lock hook 1 at the movable end of buckle closure; The lock box that fills another side of buckle closure in hinge is shaped with lock ring 6, and 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, be fixedly mounted with 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 is fixedly mounted with one and manually revolves 4, the inner end top of this screw rod in lock box fills a crushing block, and this crushing block vertically slides in the made fixedly guide groove in lock box; Crushing block with fixedly between the guide groove the made slot of corresponding lock box jointly be shaped with a squeezing groove 12, the crushing block of squeezing groove both sides and fixedly between the guide groove mirror image symmetry returning spring 11 vertically is installed respectively.
In the present embodiment, lock box adopts plastic production.
The utility model is exclusively used in Europe superscript two-phase power supply plug.
Operation principle of the present utility model is:
Extract and insert: twisting is manually revolved screw rod is retreated, and the crushing block of screw rod dress that push up the inner end increases crushing block and the fixing gap between the guide groove under the thrust of returning spring, and the metal leg of attaching plug can freely insert and extract at this moment.
Locking: twisting is manually revolved screw rod is advanced, the screw rod inner end promotes crushing block to fixedly guide groove direction displacement, crushing block and the squeezing groove fixedly jointly made between the guide groove vertically distance diminish, and the attaching plug metal leg of insertion is squeezed in therebetween fix the locking of realization metal leg.
Lock: handle is manually revolved in buckle closure upset encapsulation, and on the lock ring of padlock place, the realization stranger can not operate manually revolves handle.
