Description

Earth center springless idle lever lock cylinder

Technical Field

The invention relates to the field of locks, in particular to a spring-free idle lever lock cylinder with a geocentric structure.

Background

At present, mechanical locks widely applied to high-grade anti-theft facilities (such as safes, safety boxes and the like) and having high safety coefficients mainly comprise two types, namely a safe disc coded lock and a switch gear blade lock. For a safe disc coded lock containing 3 coded discs, the 3 coded discs are respectively a driving disc, a No. 1 driven disc and a No. 2 driven disc from inside to outside. Each disk is provided with a rectangular notch with the same size, so that the lock bolt tumbler can fall into the notch under the condition of achieving the password, and the unlocking is realized. The code grade of the disc coded lock is general, and the code grade of the 3-disc 100-code disc coded lock is 100 ten thousand. But the defect is relatively obvious, taking 3 disks with equal radius and a disk coded lock without false notches as an example, the position of the notch is judged according to slight change of torque force required by twisting the coded disk by using an old code pushing method, and then the unlocking can be completed by aligning to the three notches. Taking 3 disks of the disc coded lock with different radiuses and false notches as an example, the disc differences of the No. 1 passive plate and the No. 2 passive plate are calculated by a calculation formula by using a novel code pushing method, and the calculation can be carried out by matching with the tolerance, so that the correct code combination is found to complete unlocking. For the switch gear blade lock, the structure matching is firm and ingenious, the password combination grade is higher, but the blade can be also aimed by the technical opening tool. In addition, the blade moving space of the switch gear blade lock is limited, so that the reserved position of the lock pin is insufficient, the lock pin cannot be too long, and the success rate of prying and pressing opening is greatly increased. The principle of mechanical locks such as spring locks and blade locks of civil anti-theft facilities (such as anti-theft doors) is simple, the mechanical locks are easy to be targeted by technical opening tools, the password level is mostly about ten million levels, and the protection of high security level cannot be effectively achieved.

Compared with the prior art, the invention has the advantages that: the anti-theft lock is suitable for high-grade anti-theft products such as safes, safe cases, anti-theft doors and the like, and is not suitable for being used as a common cabinet lock, a common box lock and the like without anti-theft value due to the fact that the requirement on manufacturing accuracy is slightly high. The shaft lever is used for completing locking, and the locking technology such as a pin key, a side column and the like in the prior art is not used, so that the spring structure is completely separated, and the self stress is avoided. Therefore, the technical opening tool cannot judge opening by force according to the spring force of the lock cylinder. The shaft lever is locked in a messy code state by means of gravity, and rotation is completed by means of external force applied by a key. The lock core is reset by the artificial external force, but not the spring force of the spring reset by the position of the bolt toggle piece. The bottom of the inner side of the lock body is provided with an anti-riot groove, and broken parts fall into the groove due to violent damage, so that an obstacle can be formed between the lock core and the lock body, and the lock core is prevented from re-entering. Meanwhile, three unlocking modes of technical unlocking, technical lock breaking and violent lock breaking are prevented, and the safety level is extremely high. The traditional lock uses displacement to define the password, and changes the displacement to influence the rotation, and finally uses the rotation to define the password, so that the password grade quantity is huge. In the case where the process accuracy is sufficient, a situation in which the number of combinations of ciphers is reduced due to process limitations can be avoided. Therefore, under the condition of huge password level, the password utilization rate is improved.

As an improvement, the shaft lever track is a space occupied by the shaft lever when rotating, and taking a five-shaft lever lock as an example, the five-shaft lever lock is a first shaft lever track, a second shaft lever track, a third shaft lever track, a fourth shaft lever track, a fifth shaft lever track and a sixth shaft lever track from front to back. Before the password is pushed inwards to the lock core, the five shaft levers only occupy the front five shaft lever rails. After the code is pushed inwards, the shaft lever moves backwards by one rail unit along with the lock cylinder, and the last five rails are occupied at the moment.

As an improvement, the anti-explosion groove is positioned at the bottom of the inner side of the lock body, when parts in the lock are damaged in a technical lock breaking and violent lock breaking mode, broken parts in the lock can fall into the groove, an obstacle is formed between the lock cylinder and the lock body, and even the lock cylinder is completely locked, so that the lock cylinder cannot be pushed inwards, and further unlocking cannot be completed.

As an improvement, the shaft lever channel is a channel for the shaft lever to pass through the lock body, and is a first, a second, a third, a fourth and a fifth shaft lever channel from front to back. When the key is inserted and rotated to achieve the shaft lever code angle, the shaft lever can achieve the same angle with the shaft lever channel at the rear side of the shaft lever, so that the shaft lever can pass through the channel at the rear side of the shaft lever when the lock cylinder is pushed in and is not blocked by the lock body. Therefore, the lock takes whether the lock core can be pushed inwards or pulled outwards as the basis for judging whether the password is achieved.

As an improvement, the dummy shaft lever passage is a notch with a certain angle and is not a passage which completely penetrates through the lock body. The function is to prevent the lock core from pushing in the tool to give a given stress, then the tool is extended into the key track, the shaft lever is pushed and rotated on the shaft lever track, and the shaft lever track is found through the stress change, thereby realizing the technical opening purpose. In the face of technical opening, it has the function of mixing with the shaft lever channel.

As an improvement, the lock body fixing rod and the outer lock cylinder fixing rod can be connecting rods which play a fixing role in a screw structure, a mortise and tenon structure metal rod, a welding mode and the like.

As an improvement, the shaft lever completely depends on gravity to reach a code messing state in a locking state, and the key is inserted and rotated to reach a code state by means of torque provided by rotation of the key bit, so that the shaft lever is completely separated from the elastic force of the spring.

As an improvement, the internal cylinder structure can in any case perform a 360 ° idle rotation in the groove of the internal wall of the external cylinder assembly, which is repeated by means of the push and pull forces exerted by the key. The lock has no spring structure, completely breaks away from the elastic force of the spring, so that the damage of a technical unlocking tool and an electric drill drilling mode cannot be assisted, and the technical unlocking and violent lock breaking by the means are effectively prevented.

As an improvement, the recognizer and the key front section identification hole can play a key recognition function, and the axial rotation angle of the recognizer bulge is matched with the key front end groove, so that the code grade is increased, and the mutual opening fault-tolerant rate of the keys is reduced. In addition, the identifier (see the attached figure five) occupies the space of the middle shaft position of the key track at the innermost side of the internal lock core, and can prevent a technical unlocking tool from extending into the key track of the lock core to apply force to the fifth shaft lever to rotate, so that the technical unlocking is prevented.

The shaft lever rail 2 is a space occupied by the shaft lever when the shaft lever rotates, and takes a five-shaft lever lock as an example, and is a first shaft lever rail, a second shaft lever rail, a third shaft lever rail, a fourth shaft lever rail, a fifth shaft lever rail and a sixth shaft lever rail from front to back. Before the password is pushed inwards to the lock core, the five shaft levers only occupy the front five shaft lever rails. After the code is pushed inwards, the shaft lever moves backwards by one rail unit along with the lock cylinder, and the last five rails are occupied at the moment.

The anti-riot groove 4 is located the inboard bottom position of lock body, and when meetting the mode destruction lock of broken lock of technique, violence broken lock and destroying the part in the lock, broken part fragment can fall into the inslot in the lock, forms the obstacle between lock core and lock body, locks the lock core completely even, makes the lock core can not the internal propulsion, and then can't accomplish the unblock.

The shaft lever channel 5 is a channel for a shaft lever to pass through the lock body, and is a first, a second, a third, a fourth and a fifth shaft lever channel from front to back. When the key is inserted and rotated to achieve the shaft lever code angle, the shaft lever can achieve the same angle with the shaft lever channel at the rear side of the shaft lever, so that the shaft lever can pass through the channel at the rear side of the shaft lever when the lock cylinder is pushed in and is not blocked by the lock body. Therefore, the lock takes whether the lock core can be pushed inwards or pulled outwards as the basis for judging whether the password is achieved.

The dummy shaft lever passage 6 is a slot with a certain angle and is not a passage which completely penetrates through the lock body. The function is to prevent the lock core from pushing in the tool to give a given stress, then the tool is extended into the key track, the shaft lever is pushed and rotated on the shaft lever track, and the shaft lever track is found through the stress change, thereby realizing the technical opening purpose. In the face of technical opening, it has the function of mixing with the shaft lever channel.

The lock body fixing rod 9 and the outer lock cylinder fixing rod 14 can be connecting rods which play a fixing role in a screw structure, a mortise and tenon structure metal rod, a welding mode and the like.

The shaft lever 17 is completely dependent on gravity to reach a code messing state in a locking state, and a key is inserted and rotated to reach a code state by means of torque provided by rotation of key teeth, so that the key completely breaks away from the elastic force of a spring.

The inner lock core structure (the inner lock core front baffle plate 19, the inner lock core 21 and the bolt toggle piece 23) can complete 360-degree idle rotation in the inner wall groove of the outer lock core (the upper assembly 12 and the outer lock core lower assembly 10) under any condition, and the re-advancement depends on the pushing force and the pulling force exerted by the key. The lock has no spring structure, completely breaks away from the elastic force of the spring, so that the damage of a technical unlocking tool and an electric drill drilling mode cannot be assisted, and the technical unlocking and violent lock breaking by the means are effectively prevented.

The recognizer 24 and the key front section identification hole 27 can play a key recognition function, and the axial rotation angle of the recognizer bulge is matched with the groove at the front end of the key, so that the code grade is increased, and the mutual opening fault-tolerant rate of the key is reduced. In addition, the identifier (see the attached figure five) occupies the space of the middle shaft position of the key track at the innermost side of the internal lock core, and can prevent a technical unlocking tool from extending into the key track of the lock core to apply force to the fifth shaft lever to rotate, so that the technical unlocking is prevented.

The invention comprises the following steps: put into outer lock core lower part with interior lock core (including the spring bolt and dial the piece) and baffle before the interior lock core, later according to figure 1, as shown in figure 3, insert the axle lever back with the last subassembly axostylus axostyle of one outer lock core and insert the axostylus axostyle groove of the last subassembly of one outer lock core of back, until the subassembly is accomplished to assemble on the outer lock core, later with outer lock core subassembly alignment from top to bottom, insert outer lock core dead lever outer lock core fixed rod groove and accomplish fixedly, will control the lock body and fix with the lock body dead lever in lock core both sides and can accomplish the equipment.

The unlocking principle is as follows: the key is inserted to the deepest part, the key is rotated by 135 degrees clockwise (the key rod and the front side of the upper assembly of the first outer lock cylinder are provided with corresponding scale marks, and the scale marks are rotated to be aligned, so that the scale marks are not mixed with the structure of the lock, and the scale marks are not marked in the figure), the shaft lever is rotated by a corresponding angle to form a consistent angle with a shaft lever channel on the lock body at the rear side of the shaft lever, and the shaft lever can pass through the channel at the rear side of the shaft lever and is not blocked by the lock body. The key is pushed inwards to drive the lock cylinder and the lock tongue poking piece to move backwards, and the lock tongue poking piece is pushed out from the rear of the lock body and extends into the lock tongue rotating device. Then the key is rotated (clockwise unlocking, counterclockwise locking) to complete the final unlocking (locking). And after the key is rotated clockwise to align the scale marks, the lock cylinder is pulled outwards. At the moment, the key track of the front baffle of the inner lock cylinder is different from the key track of the inner lock cylinder, so that the lock cylinder can be pulled back to the original position by applying stress when being pulled outwards, and the key is rotated again until the inner lock cylinder is coincided with the key track of the front baffle to pull out the key.

Password level: the earth center springless idle lever lock cylinder shown in the figure is a five-shaft lever. According to the calculation mode of the password combination, the effective rotation angle interval of each shaft lever is 18 degrees to 46 degrees (the range of the rotation angle interval can be expanded by changing the size of parts), the shaft lever cannot pass through the shaft lever channel at the rear side of the shaft lever only by rotating by 1.5 degrees, and each shaft lever has at least 14 passwords in the effective interval by taking 2 degrees as password difference for eliminating errors. The lock core has five shaft levers, so the number of cipher codes is 14⁵And (4) seed preparation. The lock body length of the five-shaft lever lock is 33.5 mm. The total number of the passwords of the earth-centered springless idle lever lock cylinder is huge, so that the total number of the passwords can be correspondingly reduced, the size of parts can be increased, and the damage resistance of the earth-centered springless idle lever lock cylinder can be improved. The structural design can be made into two composite structures of a one-way lever lock (namely, a lever lock with an axial lever only on the upper side shown in the attached drawing) and a two-way lever lock with axial levers on the upper side and the lower side (namely, a lever lock with axial levers on the upper side and the lower side, which is similar to a two-way blade lock of a safe).

Detailed description of the component structure:

the shaft lever track is a space track occupied by the shaft lever when rotating, and is a first shaft lever track, a second shaft lever track, a third shaft lever track, a fourth shaft lever track, a fifth shaft lever track and a sixth shaft lever track from front to back. Before the password is not achieved to carry out the internal pushing of the lock core, the five shaft levers of the lock core only occupy the front five shaft lever rails, after the password is achieved to carry out the internal pushing, the shaft levers move backwards one rail unit along with the lock core, and at the moment, the rear five rails are occupied.

And the lock cylinder outer protrusion track is used for matching with the lock cylinder outer protrusion balance track to move.

The anti-explosion groove is a groove structure for preventing mechanical parts in the lock from being damaged by violently breaking the lock through external force. When the lock body or the lock core is broken by violent lock breaking methods such as drilling by an electric drill and the like, broken parts in the lock body and the lock core can fall into the groove. Therefore, the lock core is locked and the axial movement of the lock core is prevented between the lock core and the lock body, so that the lock can not be unlocked by destroying the lock by violence.

The shaft lever channel is a channel for the shaft lever to pass through the lock body and is a first, a second, a third, a fourth and a fifth shaft lever channel from front to back. When the key is inserted and rotated to achieve the shaft lever code angle, the shaft lever can achieve the same angle with the shaft lever channel at the rear side of the shaft lever, so that the shaft lever can pass through the channel at the rear side of the shaft lever when the lock cylinder is pushed in and is not blocked by the lock body.

The dummy shaft lever passage is a slot with a certain angle and is not a passage which completely penetrates through the lock body. The function is to prevent the lock core from pushing in the tool to give a given stress, then the tool is extended into the key track, the shaft lever is pushed and rotated on the shaft lever track, and the shaft lever track is found through the stress change, thereby realizing the technical opening purpose. In the face of technical opening, it has the function of mixing with the shaft lever channel.

The lock body fixing rod can be a connecting rod for fixing the left lock body and the right lock body in a screw structure, a mortise and tenon structure metal rod, a welding mode and the like.

The inner side of the lower component of the outer lock cylinder is provided with corresponding inner wall grooves of the outer lock cylinder at positions corresponding to the bulges of the inner lock cylinder, so that the inner lock cylinder can idle in the outer lock cylinder, and the relative positions of the inner lock cylinder and the outer lock cylinder are fixed.

The inner wall groove of the outer lock cylinder corresponds to the protruding position of the inner lock cylinder.

The upper assembly of the external lock cylinder is respectively a first, a second, a third, a fourth, a fifth and a sixth upper assembly of the external lock cylinder from front to back. The inner side of the lock core is provided with corresponding outer lock core inner wall grooves at positions corresponding to the inner lock core bulges, so that the inner lock core can idle in the outer lock core, and the relative position of the inner lock core and the outer lock core can be fixed.

The outer lock cylinder fixing rod can be a connecting rod for fixing the upper outer lock cylinder component and the lower outer lock cylinder component in a screw structure, a mortise and tenon structure metal rod, a welding mode and the like.

The external lock core shaft lever is a rotating shaft for rotating the shaft lever. The pad-shaped bulge of the shaft lever of the external lock cylinder can limit the distance of the forward and backward movement of the shaft lever and ensure that the movement error of the shaft lever is reduced to a controllable range. And when the lock core is pushed by external force, a resistance is given to the shaft lever, so that the shaft lever of the external lock core is protected.

The outer lock core shaft rod groove plays a role in fixing the outer lock core shaft rod and splicing the components on the adjacent outer lock cores.

The shaft lever and the length of the key have a corresponding rotation angle relationship. The longer the key bit, the greater the rotation angle of the shaft lever (within the valid interval) the same angle of rotation of the key, so as to achieve a specific combination of codes, which is a specific component to achieve the codes. The shaft lever takes the shaft lever track as a boundary, is short at the top and long at the bottom, and can naturally droop to a vertical state under the action of gravity so as to achieve messy code locking. The edge of the shaft lever channel can be subjected to corner cutting treatment, so that the shaft lever channel is smoother to pass through.

The external lock cylinder shaft lever track can enable the shaft lever to rotate on the external lock cylinder shaft lever, and the structure can be matched with the bearing for increasing the rotation performance of the external lock cylinder shaft lever track.

The front baffle of the inner lock cylinder is independent from the inner lock cylinder, and the bulge of the front baffle and the first bulge of the inner lock cylinder are positioned in a groove. The rotation of the inner lock cylinder does not influence the rotation of the front baffle of the inner lock cylinder, and stress can be provided for the lock cylinder to be pulled outwards after the unlocking and locking are completed. The lock core can also independently rotate to idle, so that the damage of a technical unlocking tool and an electric drill drilling mode cannot be helped, the technical unlocking and violent lock breaking by the means can be effectively prevented, and the lock core can be protected.

A key rail for a space where a key is inserted and extracted and rotated in the inner cylinder.

The inner lock cylinder can be driven by the key to rotate, so that a bolt toggle piece (which is integrally designed with the inner lock cylinder and is split into two parts for facilitating structure display) behind the inner lock cylinder is driven to rotate, and the bolt toggle piece is pushed out and pushed out from the rear of the lock body after unlocking is completed, so that the bolt toggle piece extends into the bolt rotating device to complete unlocking and locking.

The inner lock core is raised, so that the relative position between the inner lock core and the outer lock core is fixed.

The lock tongue shifting piece can idle together with the inner lock cylinder before the password is pushed inwards, but the lock tongue shifting piece rotates because the lock tongue shifting piece is positioned in the lock body at the moment, the lock tongue rotating device cannot be influenced, and the unlocking and the locking cannot be finished. After the password is pushed inwards, the bolt toggle piece is pushed out from the rear of the lock body, and at the moment, the bolt toggle piece extends into the bolt rotating device and influences the rotation of the bolt rotating device, so that the unlocking and locking are completed.

And an identifier having a certain geometry and a certain rotation angle and corresponding to the identification hole of the front end of the key. Every key and tool to lock recognizer assorted shape and angle are all inequality, and when the unmatched key inserts the back, the recognizer can not get into the identification hole of key front end, causes the key can't insert completely, and then can't exert external force to the fifth lever of inside or even all shaft levers, consequently can not accomplish and open the shutting to increase the password grade, and reduced the fault-tolerant rate of opening each other of key. Meanwhile, the length of the recognizer corresponds to that of the fifth shaft lever track, so that a technical unlocking tool can be prevented from extending into the lock core key track to apply force to the fifth shaft lever to rotate, and technical unlocking is prevented.

Each key tooth edge is subjected to corner cutting treatment, so that mechanical movement between the key tooth and the shaft lever is smoother.

The identification hole is matched with the identifier on the bolt toggle piece.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the above-described embodiment is only one of the embodiments of the present invention, and the actual configuration is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
