Technical Field

Background

All mechanical locks follow the principle of dislocation locking, and realize unlocking by mutually meshing a key groove of an active part (key) and a bulge of a passive part (locking part) to realize dislocation complementation; when the key is pulled out, the locking piece is dislocated to realize locking. Whether it is a spring lock, a reed lock or a keyless dial coded lock, it is not possible.

The lock core is the core of a mechanical lock, and more parts, such as a marble and a matched spring of the marble lock, and a locking plate and a matched spring of a reed lock, need to be added to improve the key amount, but the current lock core has limited space, and only can contain all locking functional parts by arranging part of the parts into the lock body, and the lock core needs manual assembly, and has high difficulty, high cost and low yield. The lock core and the lock body are synchronously assembled and connected into a whole, which is the most obvious characteristic of the traditional mechanical lock. Taking a common standard mortise lock as an example, the diameter of the lock hole is only 14mm at most, and the key amount does not exceed 5 × 4! Part of the springs and the pins or locking plates can only be arranged on the lock body, so that the key repetition rate is less than or equal to 1/1000, which becomes an industry standard; the traditional mechanical lock cylinder is manually assembled, and the more complex the lock cylinder, the higher the cost, the lower the yield and the easier the lock cylinder is to break down. This is the root cause that the lock core can not become an independent and integrated universal part.

Compared with the prior art, the integrated universal lock core is a cylindrical standard component, and can be fixed in a lock hole of a mortise lock and popularized to other locks. The lock core is novel in design, simple in structure and precise in matching, the matched key is equivalent to a clutch, the key is not inserted, and all functional parts are in a discrete state and can idle. The necessary procedures of gear engagement, unlocking and linkage can be completed in sequence only by a proper key, all the function pieces are precisely matched, the technical unlocking difficulty is very high, and the unique correct path for driving the lock linkage mechanism to unlock can be damaged by violence, so that the lock is the most obvious characteristic different from the traditional lock cylinder.

The scheme of the invention is explained in detail below:

the invention integrates all the parts in a sleeve in a limited space to form an independent lock cylinder assembly, which is not only very reliable, but also has the key amount theoretically up to 10 multiplied by 10! Actually, it is 6X 10! The combination of C (10,6) × a (6,6) × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 ═ 3628800 has been reached. Therefore, the key amount can be improved by at least 2 orders of magnitude compared with the traditional lock cylinder; the key is made of a semicircular arc stainless steel sheet with the thickness of about 0.8mm, a key hole in the anti-drilling cap is similar to the key, the width is only 1mm, the movable locking plate with a special shape can rotate in a forward direction or a reverse direction without limit, gear engagement can be realized only by matching with an adaptive key, unlocking or interlocking of the inner sleeve 2 and the outer sleeve 1 is completed, and after unlocking, the lock linkage mechanism is driven to finally complete opening or closing of the lock; the integrated universal lock core can be matched with standard mortise locks and most locks. The structure of the lock core of the invention determines that all parts can be produced by a non-cutting process and assembled automatically, all materials have the performance of water resistance and corrosion resistance, and the lock core has low cost, good quality and convenient standardization. The matched key is formed by bending stainless steel materials, and has high precision and good strength.

The scheme of the invention for realizing the aim is as follows: the lock core is an integrated universal piece and is fixed in a lock core hole of a traditional universal lock body through an outer sleeve 1, the outer sleeve 1 is internally provided with an inner sleeve 2 which can only do rotary motion, most of the anti-drilling cap 3 is embedded in the outer sleeve 1, and the rest of the anti-drilling cap is blocked at the outermost end of the outer sleeve 1 and can freely rotate, and the inner sleeve 2 is limited not to axially displace but can freely rotate; the inner sleeve 2 is internally provided with a non-circular upright post 5 with one end fixed at the center of the tail part of the inner sleeve 2, and functional parts such as a stator 7, a rotor 6, a hand feeling stator 7, a hand feeling rotor 9, a spring 8 and the like which are connected in series on the inner sleeve 2, the bulge at the tail end of the inner sleeve 2 is linked with a lock transmission mechanism, most of a lock latch 4 is clamped in a slotted hole of the inner sleeve 2 during locking, the rest part is in a slotted hole of the outer sleeve 1, and the excircle of the rotor 6 is propped against the lock; when the lock is unlocked, the lock bolt 4 is arranged in the slotted hole of the inner sleeve 2 and the grooves of all the movable plates 6, and the inner sleeve 2 and the outer sleeve 1 are unlocked; only the proper key can shift the corresponding moving piece 6, and then unlocking or locking is completed. Taking unlocking as an example, when a key is inserted into a lock core in a locking state through the anti-drilling cap 3 and rotates for a certain angle, all corresponding grooves of the movable plate 6 can be aligned firstly, the key continues to rotate until being aligned with a slotted hole of the inner sleeve 1, friction force generated by the rotation of the key acts on the inner sleeve 2 and forms a component force for the latch 4 clamped between the slotted hole of the inner sleeve 2 and the slotted hole of the outer sleeve 1, the latch 4 is extruded to move towards one end with small stress, and is gradually separated from the slotted hole of the outer sleeve 2 and enters virtual positions to wait for the grooves of the movable plate 6 until all the grooves are clamped between the slotted hole of the inner sleeve 2; continuing to rotate, completely separating the inner sleeve 2 from the constraint of the outer sleeve 1 to realize unlocking, and continuously rotating the inner sleeve 2 to drive the lock transmission mechanism to be linked to complete the door opening task; otherwise, the door can be closed; when the key is reversed, one moving plate 6 firstly contacts with the key bit to act on the latch 4 and drive the inner sleeve 2 and all the moving plate 6 grooves to move reversely until the inner sleeve 1 slot is aligned, the latch 4 is gradually squeezed into the slot of the outer sleeve 1, meanwhile, the moving plate 6 grooves are separated from the latch 4 gradually until the outer circles of all the moving plates 6 completely seal the inner side of the slot of the inner sleeve 2, and at the moment, the latch 4 is positioned between the inner sleeve 1 slot and the outer sleeve 1 slot to complete locking; the hand feeling moving piece 9 always rotates along with the key and is matched with the hand feeling fixed piece once per rotation to generate a hand feeling signal; when the interlocking of the inner sleeve 2 and the outer sleeve 1 is completed, the protrusion on the hand feeling moving piece is just matched with the recess of the hand feeling fixed piece 10, so that obvious hand feeling is generated, the locking is prompted to be completed, and the key can be safely drawn out. The foremost end of the key is maximized, and the moving plate is shifted when the key is extracted, so that the grooves of different moving plates 6 are in a staggered state.

The mating key is the only means to achieve the above opening/closing coherent action. The cross section of the matched key is in a semicircular arc shape, a stainless steel thin plate is preferred, the thickness is preferably 0.7-0.9mm, and teeth are arranged on two sides of the matched key;

the design principle of the invention is as follows: the integrated universal lock core and the key are applied to the clutch principle, the key is equivalent to one part of the clutch, only all clutch elements form a whole, and external force can be transmitted inwards and drives the lock linkage mechanism to realize door opening or door locking; the grooves of different moving plates 6 are usually staggered with each other and are not aligned with the slotted holes of the lock bolts 4 of the inner sleeve 2, and the fixed plates 7 are arranged between the adjacent moving plates 6, thereby not only playing a role of isolation and positioning, but also eliminating the mutual interference generated by the rotation between the moving plates 6; different depths of the teeth on the left/right sides of the key form a corresponding complementary relationship with different moving plates 6, and only when the proper key is inserted in place and rotated, all the moving plates 6 can be shifted one by one and the grooves of the moving plates are aligned. The friction generated by the rotation of the key is transmitted to the inner sleeve 2 and presses the lock bolt 4; when the lock core is locked, a small part of the latch 4 is positioned in the slotted hole of the outer sleeve 1, the rest of the latch 4 is positioned in the slotted hole of the inner sleeve 2, the inner sleeve 1 and the outer sleeve 1 are interlocked at the moment, and the lock is also in a locking state; only when the key is inserted and rotated, all the moving plates 6 are poked one by one and all the grooves are aligned, then the key is rotated until the slots of the inner sleeve 2 are aligned, at the moment, the lock latch 4 is extruded by the shearing component force of the slots of the inner sleeve 1 to enter the grooves of all the aligned moving plates 6, and most of the lock latch 4 is still left in the slots of the inner sleeve 2; the locking bolt 4 and the inner sleeve 2 can be completely separated from the constraint of the outer sleeve 1 by continuing to rotate, so that unlocking is realized, and the inner sleeve 2 simultaneously drives the locking transmission mechanism to be linked, so that the purpose of opening the door is realized; when the door needs to be closed, the key is reversed, at least one moving plate 6 contacts the right tooth of the key firstly, the moving plate 6 leads to push the latch 4 and then drives the inner sleeve 2 and the moving plate 6 to move reversely until the position of the slotted hole of the outer sleeve 1 is aligned, the latch 4 is extruded into the slotted hole of the outer sleeve 1, and the interlocking of the inner sleeve 1 and the outer sleeve 1 is completed; and when the key continues to rotate reversely, the right-side teeth are matched with all the moving pieces 6 again, and the right groove positions of all the moving pieces 6 which are staggered are aligned until the key rotates to align with the slotted hole of the inner sleeve 2, and the next unlocking is repeated. Thus by rotating continuously in time or counterclockwise. The periodic unlocking and locking process occurs every 360 degrees, and the continuous driving of the interlocking machine part linkage can be realized by repeating the action, so that the aim of opening or locking the door is realized. The hand-feeling moving piece 9 and the hand-feeling fixed piece 10 in the lock cylinder can provide prompt for correct operation, the hand-feeling moving piece 9 always rotates along with the key, when the inner sleeve and the outer sleeve are interlocked, the protrusions of the hand-feeling moving piece 9 and the recesses of the hand-feeling fixed piece 10 are matched periodically and generate obvious hand feeling, and a locking state is prompted; when the 'door locking' is confirmed to be completed, the key can be safely drawn out; and the recesses of different moving pieces 6 are dislocated when being extracted.

According to the invention, only a proper key can align all the grooves of the dislocated moving plate 6, so that the so-called 'gear shifting' is realized, then the lock bolt 4 is extruded out of the slotted hole of the outer sleeve 1 and enters the groove of the moving plate 6, and then the inner sleeve 1 and the outer sleeve 1 can be unlocked and the 'door opening' or 'door locking' task can be completed only by continuously forcibly rotating. The four-step ring is inserted, rotated, shifted and unlocked, and the unlocking cannot be completed as long as any step is wrong, and the door can not be opened or closed. When the key is removed, the groove of the rotor 6 cannot be aligned with the inner sleeve 2 to be shifted up, any external force cannot be correctly transmitted to the inner sleeve 2 to drive the inner sleeve to act, and the inner sleeve only can idle and cannot be unlocked naturally. Even if the inner sleeve 2 happens to be aligned with all the grooves of the moving plate 6, no power is used for extruding the latch 4 down to unlock the inner sleeve 1 and the outer sleeve 1, and the inner sleeve 2 cannot be rotated and opened.

The invention has unique structural design, and the lock body does not need to be provided with parts such as a spring 8 marble and the like which move in the radial direction; the anti-drilling cap 3 is blocked at the outer end of the outer sleeve 1 and can freely rotate, and the integrated lock core is hidden in the lock hole of the lock body, so that drilling and prying are effectively prevented; the C-shaped key hole on the anti-drilling cap 3 is less than 1mm wide, so that picking, smashing and vibration unlocking can be prevented, and all materials of the lock cylinder are waterproof and corrosion-resistant; the key amount of the invention is up to tens of millions of groups of unlocking technologies such as poking, picking, tinfoil, vibration and the like, the inner sleeve 2 cannot be driven to rotate even if violence is used, and the rotation of the inner sleeve is the only correct way for opening the door.

In addition, in order to meet the market demands for hierarchical management, a lock cylinder with segmented control can be adopted, and the structure of the lock cylinder is basically consistent except that the lock latch is divided into two segments (a front lock latch 41 and a rear lock latch 42), as shown in schematic diagrams 9 and 10:

the lock bolt 4 is divided into a front section and a rear section, which correspond to different moving pieces 6 respectively. The primary key controls the first stage, and the final key controls the first stage and the second stage simultaneously; when the second-stage latch is in the original state, the rear-stage latch is limited in the slotted hole of the inner sleeve and the corresponding movable sheet groove, can rotate randomly along with the inner sleeve 2 driven by the primary key and cannot enter the slotted hole of the outer sleeve 1; the primary key can only control the front-section bolt and complete the door opening/locking task; when the final key is inserted and rotated, the rear section latch is activated by the corresponding moving plate and can be extruded into the slotted hole of the outer sleeve; up to this point, the primary key is disabled, and then only the final key can be used to accomplish the "door open" or "door lock" task.

According to the integrated universal lock cylinder, due to the fact that a special structure is adopted, all movable parts (except the lock latch 4) are connected on the central upright post 5 in series, the spring 8 tightly presses the movable piece 6 and the fixed piece 7, axial displacement is extremely small, and the outer diameter of the movable piece 6 is in movable fit with the inner diameter of the inner sleeve 2; all locking elements are punched and formed, and the precision is high; more movable plates 6 and fixed plates 7 can be arranged under the same space condition, so that the combined key amount is improved by more than 2 orders of magnitude compared with the traditional mechanical lock core, and the safety is incomparable; the key hole is a narrow slit of a semicircular arc, the width is less than 1mm, and the key hole is of a gear structure, so that the unlocking of any existing technology can be prevented, the unlocking by using violent modes such as drilling, picking, prying, smashing, vibrating and the like can be prevented, the corrosion resistance and the water resistance are realized, and the reliability is extremely high; because the lock core needs to complete 4 coherent actions of key insertion, gear engagement, unlocking and unlocking in sequence, compared with the traditional lock which only has two actions of key insertion and unlocking, the lock core has the advantages that technical unlocking is very difficult, and the safety is greatly improved; because the integrated universal lock core does not need to manually install radial moving parts (such as the spring 8 and the marble) on the lock body, the integrated universal lock core can become a cylinder standard suite, not only can be quickly installed by utilizing the original lock hole of the mortise lock, but also can comprehensively replace the traditional lock core; the invention can adopt full-automatic production and assembly, greatly improves the precision, reliability and production efficiency of products, and reduces the failure rate and the cost; because the integrated universal lock cylinder has the advantages, the integrated universal lock cylinder can become an ideal matched product of an electronic lock, and a short plate with low safety of the conventional mechanical lock cylinder is supplemented.

In order to achieve the above purpose, the present invention further provides a key, a structure of the key 13 is shown in fig. 11, and the key 13 is a key matched with the integrated universal lock cylinder described in the above embodiments, and details are not repeated here.
