3. The invention relates to a mechanical damping time-limiting lock with idle lock cylinder, which adopts a mechanical damper to realize the purpose of time-limiting unlocking, the damper selected by the invention is any one of a barrel damper, a double-gear damper and a single-gear damper, and the damping time-limiting mechanism has 4 technical schemes according to different types and installation positions of the dampers, and the following specifically introduces 4 forms of the damping time-limiting mechanism:

the damper is a single-gear damper, and the single-gear damper is arranged on a damper sliding block. As shown in fig. 1 and 3, the damping time-limiting mechanism comprises a single-gear damper, a damper sliding block and a damping time-limiting spring, the single-gear damper is arranged on the damper sliding block, and the single-gear damper comprises: housing, gears, shafts, etc. The gear is disposed on any one of the housing and the shaft, the housing and the shaft form a sealed cavity, a non-smooth structure such as a vane or a protrusion is disposed in the sealed cavity to improve the force transmission efficiency, and a damping medium is disposed in the sealed cavity, and is not specifically described in this specification since the damping medium is a non-newtonian fluid, oil, air, elastic particles, and the like, which are used in the conventional damper technology (hereinafter referred to as a damping medium). The shaft and the housing form a fluid coupling-like structure. As shown in fig. 3, the gear is arranged on the shell, the single-gear damper is arranged on the damper sliding block, the shaft of the single-gear damper is fixed on the damper sliding block in a non-rotatable manner, the key hole sliding block is provided with a rack, and the gear on the single-gear damper is meshed with the rack on the key hole sliding block. When any object such as a key or an unlocking tool enters the key hole, the key hole sliding block can be pushed to move, the key hole sliding block drives the gear on the single gear damper to rotate, the torsion can be transmitted to the shaft through a damping medium when the gear rotates, the shaft cannot rotate, the shaft can transmit certain resistance to the gear, and the resistance is larger when the gear rotates at a higher speed due to the mechanical property of non-Newtonian fluid. Therefore, under the action of damping force, the keyhole slide block can drive the damper slide block to move, the damper slide block does not push against the lower part of the lock cylinder clutch any more when moving, the lock on the lock cylinder clutch is released, and the lock cylinder clutch can enter the V-shaped groove of the marble. After the key is inserted to the bottom, the keyhole slide block can not move any more, at the moment, the damper slide block can rebound to the original direction under the action of the damping time-limiting spring, the rebound process is carried out slowly due to the existence of the damping force between the shaft and the gear, and the short rebound time is the time-limiting unlocking time of the invention. At the moment, if the inserted key is the correct key matched with the lock, the V-shaped grooves on the pins on the lock core can be arranged into a straight line, the lock core can immediately enter the lock core through separation and reunion, and the lock core is connected with the unlocking shifting piece, so that the lock core can drive the unlocking shifting piece to rotate, and unlocking is completed.

And the damper is a barrel-shaped damper, as shown in the attached figures 6 and 7, the damping time-limiting mechanism comprises: barrel-shaped attenuator, damping time limit spring, barrel-shaped attenuator include: the damper comprises a damper shell, a driving shaft, a piston arranged on the driving shaft and the like. A damping medium is arranged in a piston cavity formed by the damper shell and the piston, and the damping medium is a non-newtonian fluid, oil, air, elastic particles and other substances in the existing damper technology, so that the damping medium is not specifically described in the specification (hereinafter referred to as the damping medium). The two ends of the driving shaft extend out of the damper shell, one end of the driving shaft extends into the key hole to form a key hole sliding block, and when the driving shaft moves fast, the damping medium inside the driving shaft cannot flow out in time or pressure can be transmitted to the damper shell due to the non-Newtonian fluid mechanics characteristic of the damping medium. When the driving shaft moves slowly, the damping medium in the damper can flow from one piston cavity to the other piston cavity to absorb pressure, and the damper shell can be kept static and only the driving shaft moves. When any object such as a key or an unlocking tool enters the key hole, the key hole sliding block can be pushed to move (namely, the driving shaft of the damper moves), the damper shell can move along with the driving shaft and the key due to the existence of damping force between the key hole sliding block and the shell, the damper shell or a device for locking the clutch of the lock cylinder arranged on the damper shell is separated from the clutch of the lock cylinder, the lock cylinder is unlocked in the clutch mode, and the damper can enter the lock cylinder under the action of the lock cylinder clutch spring. After the key is inserted to the bottom, the keyhole sliding block can not move any more, at the moment, the damper shell can rebound to the original direction under the action of the damping time-limited spring, damping liquid in the piston cavity can slowly flow into the other piston cavity from one piston cavity, the rebound process is slowly carried out due to the existence of damping force, and the short rebound time is the time-limited unlocking time of the invention. At the moment, if the inserted key is the correct key matched with the lock, the V-shaped grooves on the pins on the lock core can be arranged into a straight line, the lock core can immediately enter the lock core through separation and reunion, and the lock core is connected with the unlocking shifting piece, so that the lock core can drive the unlocking shifting piece to rotate, and unlocking is completed. If a matched correct key is not inserted, the lock core clutch cannot immediately enter the lock core, the damper shell rebounds to reset, the damper shell returns to the lower part of the lock core clutch again, the lock core clutch cannot enter the lock core again, the lock core clutch is locked, and the lock cannot be unlocked again.

And thirdly, the damper is a double-gear damper, as shown in the attached figures 8 and 9, the damping time-limiting mechanism comprises: double gear damper, time-limited slider, damping time-limited spring, double gear damper includes: bull gears, pinion gears, and the like. A sealed cavity is formed between the large gear and the small gear, and the parts of the large gear and the small gear, which are positioned in the sealed cavity, are also respectively provided with non-smooth structures such as blades or protrusions and the like for improving the force transmission efficiency, and the sealed cavity is internally provided with a damping medium which uses non-Newtonian fluid, oil, elastic particles and other substances of the existing damper technology, so that the damping medium is not specifically described in the specification (hereinafter referred to as the damping medium). When any one gear rotates, the torsional force is transmitted to the other gear through the damping medium, and the action principle of the hydraulic coupler is similar to that of a hydraulic coupler. As shown in fig. 9, a rack is arranged on the keyhole slider and meshed with one gear on the damper, a rack is also arranged on the same time-limited slider, and the rack on the time-limited slider is meshed with the other gear on the damper. When any object such as a key or an unlocking tool enters the key hole, the key hole sliding block can be pushed to move, the key hole sliding block drives one gear of the damper to rotate, and because damping force exists between the two gears on the damper, the other gear can also rotate, so that the time-limited sliding block is driven to move, and the lock of the damping time-limited mechanism on the lock core clutch is released. Similarly, after the key is inserted to the bottom, the keyhole sliding block can not move any more, at the moment, the time-limited sliding block rebounds to the original direction under the action of the damping time-limited spring, because the damping force exists between the two gears, the rebounding process is carried out slowly, and the short rebounding time is the time-limited unlocking time of the invention.

And fourthly, the damper is a single-gear damper, and the single-gear damper is arranged on the key hole sliding block. As shown in fig. 10 and 11, the damping time-limiting mechanism includes a single gear damper, a time-limiting slider, and a damping time-limiting spring, the single gear damper is disposed on the keyhole slider, and the single gear damper includes: housing, gears, shafts, etc. The damper housing and the shaft form a sealed cavity, a non-smooth structure such as a vane or a protrusion is arranged in the sealed cavity to improve the force transmission efficiency, and a damping medium is arranged in the sealed cavity, and the damping medium is a non-Newtonian fluid, oil, air, elastic particles and other substances in the existing damper technology, so that the damping medium is not specifically described in the specification (hereinafter referred to as the damping medium). The shaft and housing also form a fluid coupling-like structure. As shown in fig. 11, the gear is arranged on the housing, the single-gear damper is arranged on the keyhole slide block, the shaft of the single-gear damper is fixed on the keyhole slide block in a non-rotatable manner, the time-limited slide block is provided with a rack, and the gear on the single-gear damper is meshed with the rack on the time-limited slide block. When any object such as a key or an unlocking tool enters the key hole, the key hole sliding block can be pushed to move, the key hole sliding block drives the single-gear damper to move, the gear of the key hole sliding block is meshed with the gear on the time-limited sliding block, so the time-limited sliding block can be driven to move under the action of damping force, the time-limited sliding block does not abut against the lower part of the lock cylinder clutch any more, the lock cylinder clutch is released from locking, and the lock cylinder clutch can enter the V-shaped groove of the marble. After the key is inserted to the bottom, the keyhole slide block can not move any more, at the moment, the damper slide block can rebound to the original direction under the action of the damping time-limiting spring, the rebound process is carried out slowly due to the existence of the damping force between the shaft and the gear, and the short rebound time is the time-limiting unlocking time of the invention.

4. According to the mechanical damping time-limiting lock with the idle lock cylinder, the damping time-limiting mechanism is flexibly connected with the key hole sliding block through the damper and is not rigidly connected. When the lock is unlocked, a key is inserted at a higher speed, and the key hole sliding block is pushed to move so as to release the locking of the clutch of the lock cylinder. The faster the key is inserted, because of the mechanical property of the non-Newtonian fluid, the larger the shear stress is, the larger the damping force of the damper is, the smaller the relative displacement of the damper is, the longer the time required by the rebound of the damper is, and the relatively longer the unlocking limited time is; if the key is inserted too slowly, because of the mechanical property of the non-Newtonian fluid, the shearing stress of the key is smaller, the damper between the overtime lock and the key hole sliding block can absorb the mutual acting force and relative displacement, the lock cylinder clutch can not be unlocked and can not move all the time, namely, when lawless persons slowly move the key hole sliding block to adjust the marbles one by one to try to prolong the unlocking time, the lock cylinder clutch can be always kept in a locked state, and the lawless persons can not unlock the lock. Therefore, the mechanical damping time-limiting technology has stronger practicability and reliability.

5. The mechanical damping time-limiting lock with the idle lock cylinder has strong capacity of preventing technical unlocking. The principle of technical unlocking is that the position of each marble is adjusted to an unlocking position one by using factors such as machining precision errors of the lock, so that the technical unlocking is realized, but the process needs a long time. According to the mechanical damping time-limiting lock with the idle lock core, after the lock core is locked by the damping time-limiting mechanism to be in clutch, even if the position of a marble is adjusted, the lock core can not be in a V-shaped groove of the marble, so that whether the position of the marble is adjusted or not can not be judged from the outside of the lock. There is no way to determine the shape of the key by adjusting the pins without seeing the key, and there is no way to duplicate the key. The unlocking can hardly be completed within the unlocking time limited by the damping time-limiting mechanism if a correct key cannot be copied, and the mechanism can lock the lock cylinder clutch and cannot unlock the lock if the damping time-limiting mechanism exceeds the limited time. The key or the unlocking tool must be pulled out, the damper is completely reset after the key hole slide block rebounds and resets, and then a matched correct key is inserted, so that the damping time limit mechanism unlocks the lock cylinder clutch, the position of the marble is adjusted before the damper rebounds (namely within the unlocking limit time), the lock cylinder clutch enters the lock cylinder to connect the lock cylinder and the unlocking plectrum, and the key is rotated to complete unlocking.
