Description

Safety door five keyhole double-layer lock core inside-outside opening one-way two-level locks

Affiliated technical field

The present invention relates to the lockset that a kind of safety door is used, particularly a kind of safety door five keyhole double-layer lock core inside-outside opening one-way two-level locks.

Background technology

In the field of lockset that safety door uses, the structure of the lockset in known various lockset and other field is similar substantially or identical, all be by simple several lock points, single copper lock core, shell body and locking bar constitute, and, the lockset of various safety doors is the same with the lockset in other field, all continued the traditional structure pattern of opening different locks with different keys since a lot of years always, along with people to the shelter security needs, anti-sledge performance demands to the building safety door lock is more and more higher, and the anti-sledge performance of the safety door lockset of prior art is very low, and the safety door latch that has just can be pried open in 30 seconds, the shortest even just can pry open in 17 seconds, the safety door latch that has can be opened mutually, and the high-tech safety door latch that has is pretty, also fashion very, but cannot withstand a single blow, anti-strike ability is very poor, and the safety door latch of prior art exists the lock point few, the little material of lock diameter is soft, lock core is single thin, the problem that intensity and hardness are low.

Summary of the invention

The objective of the invention is to provide a kind of a kind of safety door five keyhole double-layer lock core inside-outside opening one-way two-level locks of comparing with the safety door latch of prior art with better pick-proof performance, realize that promptly five keys open the new tactic pattern of a lock simultaneously, thereby can reach the purpose of the safe mass of the more reliable pick-proof performance of safety door latch.

For realizing purpose of the present invention, a kind of safety door provided by the invention has 30 locks of 5 rows point with five keyhole double-layer lock core inside-outside opening one-way two-level locks, comprise: internal layer steel lock core, outer steel lock core, the larger-diameter steel lock that saves up and down, main casing, protecgulum, interior external-open gauche form rocking arm, the rear end protecting cover, circular pressing plate seat, pull bar, double lock bar, the locking bar fixed mount, the double lock bar rail bracket, rectangle pressing plate seat, wherein, at the internal layer lock core, on outer lock core and the main casing, design has 5 rows totally 30 counterbores and corresponding 30 coaxial apertures in angle is 5 central planes of 72 °; Design has 2 counterbores and 2 corresponding coaxial positioning holes on main casing, is used to the alignment pin of packing into, and design has the positioning track opening deep gouge of 2 72 ° of scopes on the external cylindrical surface of outer lock core, is used to the alignment pin of packing into; On the internal layer lock core, from external cylindrical surface to axis direction, on the circumference all on the position of 5 central planes of 72 ° of angles design 5 wide 2 millimeters open slots, i.e. 5 keyholes are arranged; Back end design at outer lock core has boss, external-open gauche form rocking arm in being used to pack into; Design has the centre bore of 42 millimeters of diameters on protecgulum, the front end boss of internal layer lock core is used to pack into, the front end face center design of protecgulum has boss, be used to pack in the centre bore of circular pressing plate seat, the design of the rear end face of protecgulum has boss, location in the front end counterbore of the main casing that is used to pack into, on the protecgulum also design 6 uniform locating holes are arranged, be used to pack into and be fixed on circular pressing plate seat, protecgulum and the welding of main casing ring week are located by connecting; Circular pressing plate seat is made of circular outer plate and 6 uniform welding of double-screw bolt, and rectangle pressing plate seat is made of rectangle outer plate and 6 uniform welding of double-screw bolt; On the double lock bar rail bracket design have 2 parallel to each other, and the locking bar orbit hole of axial line in same plane, design has 6 locating holes on rail bracket, is used to pack into and is fixed on rectangle pressing plate seat; Design has 2 axial lines parallel to each other on the locking bar fixed mount, and the locking bar rear end axis hole of axial line in same plane, and 2 locking bars are used to pack into; Pull bar is designed to rectangular shape, one end is designed to the open slot structure, the other end is designed to the thick middle plated construction, pin shaft hole has all been designed at the two ends of pull bar, the big end design of interior external-open gauche form rocking arm has big hole, be used to be contained in weld on the rear end boss of outer lock core and be located by connecting, the small end design of rocking arm has small sircle hole, is used for flexibly connecting with bearing pin with the back end of tie rod through hole.

The effect that safety door of the present invention is obtained with five keyhole double-layer lock core inside-outside opening one-way two-level locks is: because the internal layer lock core is the steel solid cylinder of high strength and hardness; and be designed to 30 locks of circumference 5 rows point; from the distance between 1 the nearest lock dot center line in internal layer lock core outer face to the is 24 millimeters; simultaneously; the width in each hole of 5 keyholes of internal layer lock core only is 2 millimeters; and the internal layer of an outer lock core lock core plays important protective effect; again because double lock bar; double lock bar rail bracket and pull bar all have very high intensity and hardness; and in the steel plate of safety door, connect; so; make safety door of the present invention increase substantially reliable pick-proof performance after adopting above technical scheme with the two lever locks of five keyhole double-layer core inside-outside opening one-ways; and easy to implement, thereby can reach the purpose of the more reliable safe mass of safety door latch.

Purpose of the present invention, feature and effect will be in conjunction with the embodiments, be described further with reference to accompanying drawing.
