Abstract

The utility model provides a theft-proof lock with a cylindrical key for daily life, which is mainly composed of a plastic-covered steel wire (1), a lock shell (2) and a lock body (3). The utility model is characterized in that a cylindrical lock core sleeve (4), a static core (5) arranged in the core sleeve, a rotating core (6) movably matched with the static core, pins (7) arranged in the rotating core and the static core, pin springs (8) and a shifting disk (9) are arranged in the lock shell (3). The utility model has the advantages that the cylindrical lock core is adopted, the pins are covered in the cavity of the rotating core, and foreign matters can not open the lock. The shift-proof property and the drill-proof property of the utility model are better than any sheet structure lock, and the key matched with the lock has the characteristics of low mutually unlocking rate and imitation prevention.

Description

Theft-proof lock

The utility model relates to a kind of daily life lockset.

Commercially available lockset mostly is unidirectional and two-way billiards structure greatly at present, the key that is mated use should be a word and two-way sawtooth pattern mutually, has theftproof performance preferably though install the lockset of this lock core, but it exists more easily and is stirred unlatching by the robber with foreign matters such as steel wire or steel discs, there is the high and easily imitated weak point of mutual opening rate in the perhaps problem of opening with a lock behind the drilling tool drilling lock core, and key.

The purpose of this utility model provides a kind of anti-dialling with anti-drilling performance and all gets the extremely low and difficult imitated tube spoon theftproof lock of the mutual opening rate that further improves.

The utility model is realized by following measure:

Tube spoon theftproof lock is mainly by plastic wire rope (1), lock housing (2) and lock body (3) constitute, be fixed with cylinder lock core retainer plate (4) in the lock body (3), be arranged at the quiet core of lock (5) in the core retainer plate, with quiet core can be movingly commentaries on classics core (6), be distributed in the pin (7) that changes core and quiet in-core, spring (8) and dial (9), on cylindrical commentaries on classics core (6) is axial, an annular element that becomes one with it (16) is arranged, this annular element one end face directly upwards is evenly distributed with a plurality of column pin holes, one end face of quiet core (5) directly upwards has and changes the corresponding column pin hole of core annular element, pin (7) places quiet core respectively and changes in the column pin hole of core, spring (8) is arranged in the column pin hole of quiet core, and contacts with the end of pin.Changeing core places in the centre bore of quiet core, its annular element terminal surface contacts with quiet core front end face, form movingly, be provided with one at commentaries on classics core end and can and control the dial (9) that dead bolt (11) opens and closes with its unitary rotation, the boss (10) that has a nearly quadrant on dial one end face, rotate with changeing core by dial, boss is stirred dead bolt and is opened and closed.Quiet core is fastening by pin (17) and core retainer plate, and core retainer plate is packed in the lock body by lock body pin (13).Key (19) the one end that is used with above-mentioned lockset is a cylindrical shape, is axially arranged with on the outer wall of this end corresponding to the contraposition pin-and-hole (14) that changes core annular element column pin hole, and a square key (15) is arranged on outer wall.

Among the figure:

1 plastic wire rope, 2 lock housings, 3 lock bodies, 4 lock core covers, the quiet core of 5 locks, 6 change core, 7 pins, 8 springs, 9 dials, 10 dial boss, 11 dead bolts, 12 square keys, 13 lock body pins, 14 contraposition pin-and-holes, 15 key square keys, 16 annular elements, 17 pins, 18 latch bolt springs, 19 keys.

Below in conjunction with accompanying drawing the utility model is further described:

Tube spoon theftproof lock mainly is by plastic wire rope (1), lock housing (2) and lock body (3) constitute, in lock body (3), be fixed with being of kirsite system core retainer plate cylindraceous (4), be arranged at the quiet core of lock (5) in the core retainer plate, with quiet core can be movingly commentaries on classics core (6), be distributed in the pin (7) that changes core and quiet in-core, pin spring (8) and dial (9), on cylindrical commentaries on classics core (6), axially have one with its all-in-one-piece annular element (17), one end of annular element has a little keyway, radially be evenly distributed with 6 pin through holes on this end face, radially have on one end face of quiet core and change the corresponding column pin hole of core annular element, pin (7) places the interior pin spring (8) of column pin hole of quiet core and commentaries on classics core to be located in the quiet stem stem pin-and-hole respectively, and contact with the pin end, changeing core places in the centre bore of quiet core, its annular element terminal surface contacts with quiet core one end face and forms movingly, be provided with one at commentaries on classics core end and can and control the dial (9) that dead bolt (11) opens and closes with its unitary rotation, dial one end face is provided with the boss of a nearly quadrant, rotate with changeing core by dial, boss is stirred dead bolt and is opened and closed.The end that core retainer plate inserts key has a square groove, axially has the keyway of two symmetries on its another end wall, on quiet core one end wall a square key (12) is set, and this square key places in the keyway of core retainer plate end, in case quiet core rotates in core retainer plate.Quiet core is fastening by pin (17) and core retainer plate, and core retainer plate is packed in the lock body by lock body pin (13).Cylindrical with key (19) the one end that this lockset is used, have on the outer wall of this end corresponding to the contraposition pin-and-hole (14) that changes core annular element column pin hole, and be provided with a square key (15).

When tube spoon theftproof lock is opened, (at this moment lock is in blocking), pin changes core to the pin of quiet in-core owing to the effect of pin spring, it can not be rotated, the tubular key is axially inserted in the core retainer plate of lock body, make the pin length of spring compressed, the pin that changes core and quiet in-core is in the same plane, the clockwise direction screw key is 135 ° again, changes core this moment and drives dial clockwise direction rotation together, and the dial boss withstands dead bolt, make spring (18) compression in the dead bolt, dead bolt is in the enable possition, at this moment will extract in the lock body plug hole with the plug that plastic wire rope is connected as a single entity, and lockset is opened.

The utility model has the advantages that lock core adopts tubular structure, its pin is included in the chamber of turning to core, the use foreign matters is opened, thereby its theftproof performance is better than the lockset of any unidirectional and two-way billiards structure, the key that is mated simultaneously also have mutual opening rate low, be difficult for the characteristics of copying.
