Abstract

The utility model relates to a national standard two-phase attaching plug lock. The middle of a side face of a lock box is longitudinally provided with inserting slots which are used for inserting two metal feet of an attaching plug. A nut is fixedly installed on the lock box and is used for installing a threaded rod in a thread engagement mode in the lock box. An inside end of the threaded rod inside the lock box is manufactured into a conical head. The lock box at two sides of the threaded rod conical head is respectively provided with an extrusion block and a fixed block in sequence along the radial direction. The fixed blocks installed on outside ends of the two extrusion blocks are fixedly installed on the lock box respectively. A release spring is respectively installed between one extrusion block and one fixed block. The gaps between the extrusion blocks and the fixed blocks correspond to the inserting slots on the lock box. Due to the fact that the metal feet of the attaching plug are directly inserted into a lock body to lock, the national standard two-phase attaching plug lock has the advantages of being convenient and fast to use, small in size, reasonable in structure, and scientific in design. Besides, the national standard two-phase attaching plug lock is provided with professional effect of a plug lock, and is strong in caution function.

Description

A kind of GB two-phase power supply plug latch

Technical field

The utility model belongs to field of lockset, relates to plug latch, especially a kind of GB two-phase power supply 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 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 realizes through following technical scheme:

A kind of GB two-phase power supply plug latch; Comprise lock box, buckle closure, screw rod, screw, crushing block, fixed block, vertically be shaped on the slot of two metal legs of plug-in mounting attaching plug at the middle part, a side of lock box, on lock box, install a screw; This screw is installed a screw rod in the engagement of lock box internal thread; Conehead is processed in the inner end of this screw rod in lock box, on the lock box of screw rod conehead both sides, radially is separately installed with a crushing block and a fixed block successively, and the two pairs of crushing blocks and fixed block mirror image are symmetrical set; The opposite face of two crushing blocks is processed the conical surface that matches with the conehead of screw rod inner end; The fixed block that install the outer end of two crushing blocks is packed on the lock box respectively; Returning spring all is installed, crushing block and the fixed block made slot of the corresponding lock box in gap before between crushing block and the fixed block.

And the outer end of said screw rod on lock box installs one 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 two-phase power supply plug latch; Comprise lock box 4, buckle closure 2, screw rod 10, screw 8, crushing block 11, fixed block 12; Vertically be shaped on the slot of 6 two metal legs 5 of plug-in mounting attaching plug at the middle part, a side of lock box; Side in the lock box another side is hinged with buckle closure through hinge 3, is shaped on lock hook 9 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 1, 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.On this side of buckle closure place lock box, install a screw, this screw is installed a screw rod in the engagement of lock box internal thread, and the outer end of this screw rod on lock box installs one and manually revolve 7, and conehead 14 is processed in the inner end of this screw rod in lock box; Radially both sides are separately installed with a pair of crushing block and fixed block successively on the lock box of position, screw rod inner end, and the inboard is a crushing block, and the outside is a fixed block, and the two pairs of crushing blocks and fixed block mirror image are symmetrical set; The opposite face of two crushing blocks is processed the conical surface that matches with the conehead of screw rod inner end; The fixed block that install the outer end of two crushing blocks is packed on the lock box respectively; Returning spring 13 all is installed, crushing block and the fixed block made slot of the corresponding lock box in gap before between crushing block and the fixed block.

In the present embodiment, lock box adopts plastic production.

The utility model is exclusively used in GB two-phase power supply plug.

The operation principle of the utility model is:

Extract and insert: twisting is manually revolved screw rod is retreated; The made conehead in screw rod inner end breaks away from the made conical surface of crushing block opposite face; But the crushing block that makes two radial displacements receives returning spring thrust and merges together, and the metal leg of attaching plug can freely insert and extract this moment.

Locking: twisting is manually revolved screw rod is advanced; The made conehead in screw rod inner end gets into the made conical surface of crushing block opposite face; But and the crushing block that makes two radial displacements receive conehead extruding and respectively to the both sides displacement; The attaching plug metal leg that is inserted between crushing block and the fixed block is squeezed in to be fixed therebetween, realizes the locking of metal leg.

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.
