Abstract
The utility model provides a screw antitheft lock and key, which is characterized in that the lock comprises a traditional spring lock device and a screw leading device; the traditional spring lock device is at the inner, the screw leading device is at the outer, and the both are installed concentrically, the screw leading device comprises a shell and a screw rod in the shell, and the outer end of the shell is provided with a keyhole; the key comprises a cylinder and a handle, and the cylinder is provided with a screw groove and opening teeth fitting with the screw rod. The screw antitheft lock and key provided by the utility model provide has the advantages that the keyhole contains the screw rod, so there is no moving space for a key or a universal key, and the utility model prevents unlocking by the universal key.
Description
Technical field:
The utility model relates to mechanical lock and key.
Background technology:
At present conventional lock is widely used is cylinder lock, but it makes professional unlock staff or thief rely on certain non-key-shaped tool (or title master key) because of axially inserting key operated intrinsic shortcoming, under the situation of not destroying lockset, easily lock is opened.Therefore, the theftproof performance of conventional lock is poor, usually make us feel dangerous.
Summary of the invention:
The purpose of this utility model provides a kind of theftproof lock, and ' can prevent technology unlockings such as MASTERKRY effectively, be that the antitheft level of lockset reaches a new height.
The utility model provides a kind of spiral theftproof lock and key, it is characterized in that: lockset is made of traditional spring lock device (1) and spiral gatherer (2), tradition spring lock device (1) is in the lining, spiral gatherer (2) outside, both coaxial settings, spiral gatherer (2) is by screw rod (22) formation of housing (21) and housing (21) lining, and keyhole (25) is arranged on the outer end of housing (21); Key (3) is to constitute by cylindrical shell (31) with (32), the helicla flute (33) that matches with screw rod (22) is arranged on the cylindrical shell (31) and open tooth (34).During work, key (3) inserts lockset through keyhole (25), when key (3) cylindrical shell (31) touches the helicoid of screw rod (22), under axial compression, the spiral part of screw rod (22) enters the helicla flute (33) of key (3), screw rod (22) rotates, make key (3) enter spring lock device (1) by spiral gatherer (2), unlatching tooth (34) unlocking spring lock device (1) on the key (3), languid is stirred by the lock core (12) of spring lock device (1) in the termination of key (3).
Spiral theftproof lock and key that the utility model provides, the lift angle of its screw rod (22) and helicla flute (33) is 15 °～70 °, is preferably 20 °～40 °, to obtain certain resistance.
Spiral theftproof lock and key that the utility model provides can be equipped with lining (23) between its housing (21) and screw rod (22), to prevent screw rod (22) wearing and tearing.
Spiral theftproof lock and key that the utility model provides can be equipped with rolling bearing (24) between its housing (21) and lining (23), lining (23) rotates with screw rod (22), reduce the wearing and tearing of lining (23).
Spiral theftproof lock and key that the utility model provides, its spring lock device (1) can have many row's pellets shot from a slingshot (11), at keyhole (25) correspondingly many teeth groove are arranged, and correspondingly many rows' unlatching tooth (34) is arranged on the key (3), to strengthen theftproof performance.
The spiral theftproof lock that the utility model provides and the advantage of key are: owing in the keyhole screw rod is housed, does not just have the radially movable space of key or MASTERKRY, thereby prevent to unblank with MASTERKRY.
Description of drawings:
Fig. 1 is the structural representation of spiral theftproof lock;
Fig. 2 is the structural representation of key.
The specific embodiment:
Embodiment 1
Lockset is made of traditional spring lock device (1) and spiral gatherer (2), tradition spring lock device (1) is in the lining, spiral gatherer (2) outside, both coaxial settings, spiral gatherer (2) is to be made of the lining (23) of housing (21) and housing (21) lining and screw rod (22), very close to each other between lining (23) and the screw rod (22), being provided with between lining (23) and the housing (21) on the outer end of rolling bearing (24), housing (21) has keyhole (25); Key (3) is to constitute by cylindrical shell (31) with (32), the helicla flute (33) that matches with screw rod (22) is arranged on the cylindrical shell (31) and open tooth (34); The lift angle of the helicla flute (33) of the spiral part of screw rod (22) and key (3) cylindrical shell (31) is 20 °.
During work, key (3) inserts lockset through keyhole (25), when key (3) cylindrical shell (31) touches the helicoid of screw rod (22), under axial compression, the spiral part of screw rod (22) enters the helicla flute (33) of key (3), screw rod (22) rotates with lining (23), make key (3) enter spring lock device (1) by spiral gatherer (2), unlatching tooth (34) unlocking spring lock device (1) on the key (3), languid is stirred by the lock core (12) of spring lock device (1) in the termination of key (3).
Because keyhole (25) lining does not have radially movable space, thereby prevents to unblank with MASTERKRY.
Lockset is made of traditional spring lock device (1) and spiral gatherer (2), tradition spring lock device (1) is in the lining, spiral gatherer (2) outside, both coaxial settings, spiral gatherer (2) is to be made of the lining (23) of housing (21) and housing (21) lining and screw rod (22), very close to each other between lining (23) and the screw rod (22), being provided with between lining (23) and the housing (21) on the outer end of rolling bearing (24), housing (21) has keyhole (25); Key (3) is to constitute by cylindrical shell (31) with (32), the helicla flute (33) that matches with screw rod (22) is arranged on the cylindrical shell (31) and open tooth (34); The lift angle of the helicla flute (33) of the spiral part of screw rod (22) and key (3) cylindrical shell (31) is 25 °, there are three row's pellets shot from a slingshot (11) spring lock device (1) lining, be mutually 120 °, keyhole (25) has three teeth groove that are mutually 120 °, has three rows to be mutually 120 ° unlatching tooth (34) on the key (3).
During work, key (3) inserts lockset through keyhole (25), when key (3) cylindrical shell (31) touches the helicoid of screw rod (22), under axial compression, the spiral part of screw rod (22) enters the helicla flute (33) of key (3), screw rod (22) rotates with lining (23), make key (3) enter spring lock device (1) by spiral gatherer (2), unlatching tooth (34) unlocking spring lock device (1) on the key (3), languid is stirred by the lock core (12) of spring lock device (1) in the termination of key (3).
Because screw rod is equipped with in keyhole (25) lining, does not just have the radially movable space of key or MASTERKRY, thereby prevent to unblank with MASTERKRY.
