Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of structure is simple, the door lock of switch electricity meter box easily.

For achieving the above object, the utility model provides following technical scheme: a kind of door lock of electricity meter box, comprise casing and case lid, wherein: described case lid is provided with latch-up structure, described latch-up structure comprises and turns core, brace and two locking bars, described brace two ends are provided with screwed hole, described locking bar one end is provided with connecting hole, locking bar is threadedly connected to brace through described connecting hole by screw, described brace is fixedly connected on and turns on core, the described core that turns is rotationally connected with case lid, described casing is provided with two snap closes, described snap close is provided with the lockhole passed for locking bar.

By adopting technique scheme, rotation turns core and brace can be driven to rotate, thus drive locking bar enters the lockhole on snap close, realize the locking of case lid, simple to operate, can frequent switch easily during use, when electricity meter box often opened by needs, easy to use, avoid opening situation about all will first unblank at every turn; Brace is provided with screwed hole, thus can be directly fixed by screw, clamping locking bar, structure is simple, is connected firmly; Adopt the setting of double-rod structure, blocking effect is better, also avoids causing excessive pressure to single rod member and bending; Direct employing locking bar is connected with brace, eliminate intermediate transmission structure, save space, and structure is simpler.

The utility model is set to further: described brace is also provided with and prevents from rotating excessive block.

By adopting technique scheme, block can be conflicted with case lid when rotating to certain angle, thus stop rotation, the rotation being set to brace of block provides suitable scope, avoiding brace rotates excessively, make the position of locking bar produce larger skew, the situation that even two bars collide with each other occurs.

The utility model is set to further: described lockhole is set to elongate holes, and described lockhole width is identical with locking bar width.

By adopting technique scheme, brace is when rotating, and locking bar position is the way moving that lockhole direction and snap close in-plane occur, and lockhole being set to strip can hold, moving direction arrange width from, hold the motion of locking bar lockhole in-plane; Lockhole width is identical with locking bar width, decreases the size of lockhole on the one hand, takies less space, also makes the fixing more stable of case lid on the other hand, avoids the situation of case lid pitching.

The utility model is set to further: the lockhole of two described snap closes is coaxial, and described locking bar bending is arranged.

By adopting technique scheme, snap close lockhole is coaxial, two snap closes are positioned at two positions on same one side of casing, process convenient, location comparison is fixed, and takies less space, the bending of locking bar is arranged, the position of the other end of locking bar is made to be displaced to the position of snap close, rational in infrastructure, take up room less.

The utility model is set to further: described locking bar is provided with chamfering at the other end of relative junction plate.

By adopting technique scheme, the setting of chamfering makes coordinating of the lockhole of locking bar and snap close more steady, avoids less offset occurring and stopping that locking bar enters, the situation generation that latch-up structure cannot normally be worked.

The utility model is set to further: described case lid is also provided with guide pad, and described guide pad is provided with the pilot hole passed for locking bar.

The utility model is set to further: described guide pad is set to two pieces, and lays respectively at snap close both sides.

By adopting such scheme, pilot hole is identical with keyhole shape, uses pilot hole that locking bar can be helped better to locate, make the position more accurate stable of locking bar, and lock time, reduce case lid stressed time, the arm of force that locking bar is stressed, avoids locking bar to be out of shape under the effect of external force and fractures.
