Description

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

Art

The present invention relates to a kind of lockset of safety door, 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, known various lockset is substantially similar or identical with the structure of the lockset in other field, all by simple several lock point, single copper lock core, shell body and locking bar are formed, and, the lockset of various safety door is the same with the lockset in other field, very for many years all carry over the traditional structure pattern of opening different locks with different keys always, along with people are to shelter security needs, more and more higher to the requirement of the anti-sledge performance of building safety door lock, and the anti-sledge performance of the safety door lockset of prior art is very low, some safety door latchs just can be pried open for 30 seconds, the shortest even just can pry open for 17 seconds, some safety door latchs can be opened mutually, the high-tech safety door latch had, pretty, also very fashion, but cannot withstand a single blow, anti-strike ability is very poor, there is lock point less in the safety door latch of prior art, the little material of lock diameter is soft, lock core is single thin, intensity and the low problem of hardness.

Summary of the invention

The object 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 compared with the safety door latch of prior art with better pick-proof performance, namely realize the new tactic pattern that a lock driven by five keys simultaneously, thus the object of the safe mass of the more reliable pick-proof performance of safety door latch can be reached.

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

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

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