Description
Technical field
The utility model relates to a kind of case lock, particularly a kind of lock of ammeter box.
Background technology
General common padlock or the drawer-lock of using of existing ammeter box prevents from arbitrarily to open chamber door.The shortcoming of this lock is: 1, because each lock all has specific key, make troubles for managerial personnel's unlatching chamber door.2, the long-term use especially used having under the aqueous vapor environment, gets rusty easily.3, on casing and chamber door, increase the maybe fixedly operation of lock body of mechanical snap, improved manufacturing cost.Use macromolecular material cast-in-block ammeter box for a kind of of present appearance, since fixing relatively more difficult with screw on casing and case lid, more be necessary to design a kind of kilowatt-hour meter box lock easy to use newly.
Summary of the invention
The purpose of this utility model provides a kind of kilowatt-hour meter box lock easy to use.
The technical scheme that realizes this purpose is, a kind of kilowatt-hour meter box lock easily, comprise lock body and key two parts of being installed on the ammeter box, lock body comprises "T"-shaped locking bar and nut, the top of locking bar is the disk that has boss, and the bottom is a cylindrical bar, and the screw thread that is connected with nut is arranged at the bottom of this cylindrical bar, key be one have handle in the disk of shrinkage pool is arranged, the boss shape on shrinkage pool on this disk and the lock body disk matches.
The aperture that parallels with disk plane is arranged on the boss of said lock body in the such scheme.The effect of this aperture is can carry out lead sealing after case locks.
The boss of said lock body is shaped as triangle or polygon in the such scheme.The selection of shape will be considered the convenience of processing and using.
The lock body mounting hole of step is arranged at the bottom of the case lid of said ammeter box and the case in the such scheme, and the mounting hole on the case lid is installed "T"-shaped locking bar, and the mounting hole at the bottom of the case is installed nut.
On near in the such scheme lock body mounting hole of said ammeter box case lid the sidewall aperture is arranged, there is Plastic cap the outer end of the lock body mounting hole at the bottom of the case.The effect of this aperture is to draw the lead sealing line, and the effect of plug is to make the nut location.
The lock body of said kilowatt-hour meter box lock and key can be with metal or plastics manufacturings in the such scheme.
The using method of this kilowatt-hour meter box lock easily is, at first that case lid and case bottom is good, make both lock body mounting hole alignment, respectively "T"-shaped locking bar and nut are put in the mounting hole, make again in the boss insertion shrinkage pool on the key on the locking bar, the key handle, locking bar is rotated thereupon, and its terminal screw thread just screws with nut, finishes the work of lock case, can pass through on the locking bar boss in case of necessity and the aperture on the case lid mounting hole sidewall, carry out the lead sealing of lock body.When needs are opened ammeter box, use the boss of key backward rotation locking bar to get final product.
This kilowatt-hour meter box lock easily and existing case lock relatively have following advantage: one, because key is special and general, is convenient to the supvr and uses; Two, because lock body separates fully with casing, saved the fixedly trouble of lock body; Three, simple in structure, reduce cost, and can use the plastics manufacturing, be difficult for getting rusty.
