Abstract

the application discloses a novel marble anti-theft lock head. In the technical scheme of the invention, the marble 3 adopts a plane (C) structure, and a return groove is machined on a single side, so that the absolute value of the cipher key amount of the marble is effectively improved, and the locking instability and the structural unbalance of undersize cipher key amount caused by that the marble 3 adopts a circular arc or V-shaped return groove to move up and down to feed and withdraw are avoided; the marble 6 uses a plane type port (sharp edge) to locate the drop groove, so that the locking safety performance is improved. The arrangement of the intervention sleeve 4 strengthens the reliability and the practicability of a marble cross (90-degree) double-linear motion control structure mode. The control structure mode of marble crossing (90-degree) double-linear motion can improve the key value to 5 mm and strengthen the functional reliability of the key amount; the marble locking control line is changed into a plane (C), and straight-edge return grooves (sharp edges) or cylindrical holes (sharp edges) are used for unlocking, so that the existing unlocking method can be completely rejected, meanwhile, the uniqueness of a key is strengthened, and the possibility of mutual unlocking is avoided.

Description

Novel cylinder anti-theft lock

Technical Field

the invention belongs to mechanical locks, and relates to a traditional anti-theft lock head with a marble as a control function. Belongs to the field of safety precaution.

Background

Various techniques exist for unlocking locks, such as: the lock has the advantages that the lock has a common point of single hook, impact, electric impact and the like, and the lock core is required to be fastened to generate pre-opening pressure, and then the position of a marble is forced to move to achieve the unlocking purpose; the traditional pin tumbler lock head controls pins to withdraw from a (straight line) interference area (a lock cylinder) under the action of a key to complete unlocking, a pin tumbler hole tangent line (the outer diameter of the lock cylinder) is a pin tumbler locking control line, and adjacent keys (key amount) (123456 and 113456 …) are mutually separated due to manufacturing reasons.

Disclosure of Invention

In order to reject the pre-fastening action in the technical level and prevent the mutual opening of keys, the invention adopts a control structure mode of marble intersection (90 degrees) double-linear motion and completely arranges the unlocking function in a marble system. The specific technical scheme is as follows: an arc-shaped or V-shaped groove 10 (a single groove) (see figure 4) is arranged at any centripetal position of an inner hole of the lock body and is communicated along the axis; two rows of marble holes which are vertical to each other are drilled on the lock core, the axial positions are equal, the marble 3 hole is communicated with the key groove, and the marble 6 hole is vertically communicated with the marble 3 hole. The bullet holes are respectively provided with a special-shaped main control bullet 3 and a locking bullet 6 (the end face is sharp) (comprising a multifunctional intervention sleeve 4). The cylinder 3 is provided with a C plane, and the D position is provided with an unlocking straight-edge return groove (sharp edge) or a cylindrical hole (sharp edge).

The working principle of the structure is as follows: under the action of the surface of the marble 3C, the marble 6 falls into the groove 10 of the lock body, and the lock core is in a locked state (see figure 2). When the key 9 is inserted, the marble 3 moves to the position where the center of the return groove at the position D coincides with the central axis of the marble 6, the lock core is in the openable position (see figure 3), at the moment, the key 9 is rotated, under the rotating force of the lock core, the marble 6 slides into the lock core by utilizing the arc or inclined surface of the groove 10 of the lock body to enter the return groove, and the lock is opened. The lock core is rotated to the position shown in figure 3, due to the action of the intervention sleeve 4, the spring force pulls the marble 6 out of the return groove and pushes the marble 6 into the lock body groove 10, the key is pulled out, in the intervention of the intervention sleeve 4 (the marble 3 is stopped to rotate possibly), the marble 6 is stably superposed with the plane C, and the marble 3 returns to the control position.

In the technical scheme of the invention, the marble 3 adopts a plane (C) structure, and a return groove is machined on a single side, so that the absolute value of the cipher key amount of the marble is effectively improved, and the locking instability and the structural unbalance of undersize cipher key amount caused by that the marble 3 adopts a circumferential arc or V-shaped return groove to move up and down to feed and withdraw are avoided; the marble 6 uses a planar port (sharp edge) to find a position falling groove, so that the locking safety performance is improved, and the lock core can still be firmly locked by a margin value (the accurate amount difference of the position finding falling groove) of 0.1 mm; the arrangement of the intervention sleeve 4 strengthens the reliability and the practicability of a marble cross (90-degree) double-linear motion control structure mode.

The control structure mode of marble crossing (90-degree) double-linear motion can improve the key value to 5 mm and strengthen the functional reliability of the key amount; the marble locking control line is changed into a plane (C), and straight-edge return grooves (sharp edges) or cylindrical holes (sharp edges) are used for unlocking, so that the existing unlocking method can be completely rejected, meanwhile, the uniqueness of a key is strengthened, and the possibility of mutual unlocking is avoided.

Detailed Description

The lock head comprises lock body 1 lock core 2, processes fluted 10 on the lock body 1, and processing has the key groove on the lock core, is equipped with in the lock core: a main control marble 3, a locking marble 6, an intervention sleeve 4, a spring 5 and a spring 7. The marble 3 and the spring 7 are sealed by a plug 8, and the marble 6, the intervention sleeve 4 and the spring 5 are coaxially assembled into a whole. The marble 3 falls on the bottom edge of the key groove under the pressure of the spring 7, the marble 3C plane is propped against the marble 6 to lock the lock core, and the intervention sleeve 4 is synchronously attached to the C plane under the pressure of the spring 5 to control the marble 3. The key 9 is inserted into the key groove, the lock core is rotated, and the lockset is unlocked. And (3) turning the lock core to an opening position, withdrawing the key, returning the marble 6 to a control position, and locking the lock core.
