Abstract
Disclosed is a pipeline valve gate lock which comprises a lock cylinder. The valve gate lock is characterized by consisting of a cylindrical lock body formed by a left half block and a right half block, ring locking grooves are respectively arranged on the inner walls of the lower portions of the two half blocks, locking rings and backing rings are locked into the grooves, fixing plates are respectively arranged on the inner walls of the upper portions of the two half blocks, lock plungers with lock bolt grooves are fixed in the fixing plate of the right half block, the lock cylinder is fixed into the fixing plate of the left half block, lock bolt rotary moving grooves are disposed on the fixing plates corresponding to lock bolts, lock plunger holes are respectively disposed at two ends of the moving grooves; and length of the lock plungers match with the shape of the lock bolts to guarantee reliable opening and closing after the lock plungers are inserted into the lock plunger holes. When locked up, the valve gate lock is restricted because an upper position, a middle position and a lower position of the valve gate lock contact with a valve gate body, thereby having firm structure. As only lock holes of a product expose outside, other structures are all placed in the cylindrical lock body, thereby the valve gate lock can prevent human damage, and is safe and reliable. As the lock body is formed by the left half bock and a right half block and not restricted by environment, thereby having convenient use. Besides, the valve gate lock is suitable for being used to various valve gates, and has wide applicability and economic and practical effects.
Description
Technical field
The utility model relates to a kind of lockset, particularly a kind of pipeline valve door lock.
Background technique
At present, pipeline valve does not generally have locking device, and by mistake open and close, normally use easily by influence for particularly outdoor valve, the waste resource.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, and is safe and reliable, the pipeline valve door lock that applicability is wide.
The purpose of this utility model is achieved in that the pipeline valve door lock comprises lock core, it is characterized in that it is by the cylindrical shape lock body of being made up of its left and right halves, corresponding annular groove is arranged respectively on the lower inner wall periphery of its left and right halves, snap in the circular arc ring snap ring in the annular groove, gasket ring, corresponding semicircle fixed plate is arranged respectively on the upper inside wall periphery of its left and right halves, there is vertical semicircle orifice at the diametral plane center of semicircle fixed plate, wherein be fixed with horizontal locking bolt respectively in the fixed plate both sides of right half block, locking bolt outer end inner face has vertical lock tongue slot, fixed lock core in the intermediate radial of left side half block fixed plate, the lock core inner end connects vertical sheet dead bolt, have dead bolt rotary moveable groove on the fixed plate of corresponding dead bolt, the two ends of loose slot have the locking bolt hole, the length of locking bolt matches with the shape of dead bolt, guarantees can reliably open after locking bolt inserts the locking bolt hole, close.
The utility model is owing to adopt above design, during locking, the circular arc snap ring of bottom snaps in the spool block and the space between the valve bolt nut of valve, add gasket ring as required, about the restriction lock body, move left and right, the middle part is by plane contact on fixed plate lower plane and the valve seal nut, the restriction lock body moves down, circular hole by fixed plate surrounds the screw mandrel of valve and limits the lock body move left and right, and the plain cushion that the handle place is turned round by plane on the fixed plate and valve screw mandrel in top contacts with nut, and the restriction lock body moves up, product is except that lockhole exposes, other structure all in the cylindrical shape lock body, can prevent artificial destruction, and is safe and reliable.Lock body is made up of its left and right halves, is not subjected to environmental constraint, and is easy to use.Be fit to various valves and use, applicability is wide, and is economical and practical.
