Abstract
The utility model relates to a lock core structure of a spring lock adopting a pentagonal key, which belongs to the technical field of novel lock manufacture. The lock core structure consists of an outer sleeve, a lock core, balancing springs, an outer spring, a spring reed, an opening sealing strip, an eccentric shaft, an insertion pin pulling rod, a positioning pin, a rest spring and the pentagonal key, wherein the lock core is inserted into the outer sleeve and is tightly propped to rotate by the reset spring, the rotating angle is positioned through the positioning pin, the balancing springs are arranged in the lock core, the outer spring is arranged in the outer sleeve, the spring reed is propped on the outer spring, and the opening sealing strip is fixed on the outer sleeve arranged outside the spring reed. When the lock core structure is used, the pentagonal key is inserted into a lock core hole matched with the pentagonal key, the lock core can only rotate when the lengths of the balancing springs arranged on five edges corresponding to tooth-shaped grooves all conform to the outer circle surface of the lock core, the insertion pin pull rod is pulled to do displacement by the eccentric shaft, and the lock is unlocked. The unlocking and the new key making difficulty is increased, the safety is improved, and the lock core structure has the advantages of reasonable design, novel structure and the like and is convenient to use.
Description
Technical field
The utility model relates to a kind of cylinder of spring lock structure of five jiaos of type keys, belongs to novel lockset manufacturing technology field.
Background technology
In the middle of the lockset of frame for movement, cylinder lock accounts for major part, in order to prevent to fake or lawless person's the behavior of unblanking, lock core structure has carried out many distortion, and cross recess is arranged, keyhole shape such as half slot, but the time not length counterfeit or fake producer will appear, so will bring in constant renewal in.
Summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of cylinder of spring lock structure of simple in structure, easy to use, five jiaos of type keys with anti-pirate of the open function is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of cylinder of spring lock structure of five jiaos of type keys, and by overcoat, lock core, the trim pellet shot from a slingshot, outer pellet shot from a slingshot, pellet shot from a slingshot spring, sealing strip, eccentric shaft, latch pull bar, alignment pin, return spring and pentagon key are formed, wherein, lock core inserts in the overcoat, and holds out against revolution by return spring, angle of revolution, alignment pin location, the trim pellet shot from a slingshot is packed in the lock core, and outer pellet shot from a slingshot is packed in the overcoat, and the pellet shot from a slingshot spring withstands on the outer pellet shot from a slingshot, sealing strip is fixed in outer the putting in the pellet shot from a slingshot spring outside, eccentric shaft is located at the inner face of lock core, and the through hole of latch pull bar one end penetrates on the eccentric shaft, and the pentagon key inserts in the lock core.
Described five jiaos of type keys have the seamed edge of five projections, wherein there is a seamed edge to be longer than or to be shorter than other seamed edge, orientation when inserting with normal key, emboss pit on every seamed edge all separately and the trim pellet shot from a slingshot in the pairing lock core match, make the external surface of trim pellet shot from a slingshot concordant with the lock core outer round surface.
The described outer return spring groove and the return spring, five that are provided with and cooperation corresponding with lock core of putting arranged the pellet shot from a slingshot holes, and be provided with the alignment pin that cooperates with the lock core locating slot, the overcoat external surface can cooperate with the lockset of Any shape, forms by five novel locksets that seamed edge is key operated.
When the utility model uses, five jiaos of type keys are inserted in the lock core hole that cooperates with it, and when the length of the trim pellet shot from a slingshot of all the serrate slot correspondences on five seamed edges was all consistent with the lock core outer round surface, lock core can rotate, and by the displacement of eccentric shaft pulling latch pull bar, thereby open lockset.When any one serrate slot of any seamed edge of five jiaos of type keys and trim pellet shot from a slingshot do not match, all cause the pellet shot from a slingshot pin to be gone in the pellet shot from a slingshot hole, lock core can not rotate, increased the difficulty of unblanking with new bitting, improved safety, had reasonable in design, novel structure, advantage such as easy to use.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, overcoat, 2, lock core, 3, the trim pellet shot from a slingshot, 4, outer pellet shot from a slingshot, 5, the pellet shot from a slingshot spring, 6, sealing strip, 7, eccentric shaft, 8, the latch pull bar, 9 alignment pins, 10, return spring, 11, the pentagon key.
The specific embodiment
Embodiment: structure as shown in drawings, by overcoat 1, lock core 2, trim pellet shot from a slingshot 3, outer pellet shot from a slingshot 4, pellet shot from a slingshot spring 5, sealing strip 6, eccentric shaft 7, latch pull bar 8, alignment pin 9 and pentagon key 10 are formed, wherein, lock core 2 inserts in the overcoat 1, and hold out against revolution by return spring 10, angle of revolution, alignment pin 9 location, trim pellet shot from a slingshot 3 is packed in the lock core 2, outer pellet shot from a slingshot 4 is packed in the overcoat 1, pellet shot from a slingshot spring 5 withstands on the outer pellet shot from a slingshot 4, and sealing strip 6 is fixed in outer the putting in pellet shot from a slingshot spring 5 outsides, and eccentric shaft 7 is located at the inner face of lock core 2, the through hole of latch pull bar 8 one ends penetrates on the eccentric shaft 7, and pentagon key 11 inserts in the lock core 2.Described five jiaos of type keys have the seamed edge of five projections, wherein there is a seamed edge to be longer than or to be shorter than other seamed edge, orientation when inserting with normal key, emboss pit on every seamed edge all separately and the trim pellet shot from a slingshot in the pairing lock core match, make the external surface of trim pellet shot from a slingshot concordant with the lock core outer round surface.The described outer return spring groove and the return spring, five that are provided with and cooperation corresponding with lock core of putting arranged the pellet shot from a slingshot holes, and be provided with the alignment pin that cooperates with the lock core locating slot, the overcoat external surface can cooperate with the lockset of Any shape, forms by five novel locksets that seamed edge is key operated.During use, five jiaos of type keys are inserted in the lock core hole that cooperates with it, and when the length of the trim pellet shot from a slingshot of all the serrate slot correspondences on five seamed edges was all consistent with the lock core outer round surface, lock core can rotate, and by the displacement of eccentric shaft pulling latch pull bar, thereby open lockset.When any one serrate slot of any seamed edge of five jiaos of type keys and trim pellet shot from a slingshot do not match, all cause the pellet shot from a slingshot pin to be gone in the pellet shot from a slingshot hole, lock core can not rotate, increased the difficulty of unblanking with new bitting, improved safety, had reasonable in design, novel structure, advantage such as easy to use.
