Abstract

The utility model discloses a mechanical lock, and relates to locksets. The mechanical lock aims at solving the problem that an existing lockset with a single lock cylinder is poor in antitheft performance. The mechanical lock comprises a first lock cylinder, a second lock cylinder, leaf springs, a spring bolt, a lock body, a plurality of springs and a plurality of marbles. The first lock cylinder is arranged inside the second lock cylinder. The lock body, the first lock cylinder and the second lock cylinder are provided with a plurality of marble holes. Three marbles and a spring are installed inside each marble hole. The leaf springs matched with the marbles are installed between the first lock cylinder and the second lock cylinder. The spring bolt is arranged on the second lock cylinder. A key hole is formed in the first lock cylinder. The radial cross section of the tail end of the first lock cylinder is composed of a semi-circle and a sector with the angle of 135 degrees, wherein the semi-circle and the sector have the same center of the circle. The radial cross section of the tail end of the second lock cylinder is in a semi-circle-ring shape, wherein the outer diameter of the semi-circle-ring shape is equal to the radius of the sector with the angle of 135 degrees. The inner diameter of the semi-circle-ring shape is equal to the radius of the semi-circle. The first lock cylinder is matched with the second lock cylinder. The mechanical lock can not be opened by other tools except for a key, and safety of the mechanical lock is ensured.

Description

Mechanical lock

Technical field

The utility model relates to a kind of lockset.

Background technology

The lockset that is generally used in door and window or cupboard at present normally arranges lock core in lock body, be provided with members such as spring and hoodle in the lock core, the locking effect that snaps into by spring, hoodle, and when key inserts, hoodle is held and lockset is opened, the lockset that this kind is commonly used, owing to utilize unlocking tool it can be pried open, the robber uses better simply instrument just hoodle can be held and lockset is opened, and does not have anti-theft feature.

The utility model content

The utility model is the relatively poor problem of lockset anti-theft feature of the present single lock core of solution, and then proposes a kind of mechanical lock.

The utility model is to address the above problem the technical scheme of taking to be: mechanical lock comprises first lock core, second lock core, reed, dead bolt, lock body, a plurality of springs and a plurality of pellet shot from a slingshot, first lock core is contained in second lock core, lock body, first lock core and second lock core are provided with a plurality of pellets shot from a slingshot hole, in each pellet shot from a slingshot hole pellet shot from a slingshot and spring are housed, the reed that cooperates with pellet shot from a slingshot is installed between first lock core and second lock core, dead bolt is contained on second lock core, be provided with keyhole at first lock core, the radial section of the first lock core tail end constitutes by the semicircle that partly has the phase concentric and 135 ° are fan-shaped, the radial section of the tail end of second lock core be semi-round ring shape wherein the external diameter of semi-round ring shape equal 135 ° of fan-shaped radiuses, the internal diameter of semi-round ring shape equals semicircular radius, and first lock core cooperates with second lock core.

The beneficial effects of the utility model are: the utility model is simple in structure, by two-stage lock core combination, can prevent that any unlocking tool from prying open, and reaches best antitheft effect.
