Description

Mechanical damping time-limiting lock without rotating key

Technical Field

The invention belongs to the field of anti-theft locks, and particularly relates to a mechanical damping time-limiting lock without a rotating key.

Background

Although the existing anti-theft locks in the market have various shapes and varieties, most of the locks rotate the key to drive the lock cylinder to rotate to complete the unlocking action. The basic principle of the lock is that the lock core is locked by the marble in the lock core, so that the lock core cannot rotate, and other mechanisms of the lock cannot be driven to operate, and the lock cannot be unlocked. The lock is limited by a lock core structure and a key structure, and the marble in the lock core is generally very small and can be easily twisted off, so that a lawless person can take the lock with the lock, and the lawless person uses a tool similar to a key to insert into the lock core to forcibly rotate, so that the marble is twisted off, the lock core can be rotated, the anti-theft lock can be opened, and the lock is locked in a large potential safety hazard. The invention discloses a mechanical damping time-limited lock without a rotating key, which is different from the prior lock in the basic technical principle. When the key is inserted into the lock, the pins on the lock core are unlocked without rotating the key, the lock core automatically bounces under the action of the lock core spring, the lock core lock plunger on the lock core unlocks the unlocking handle, and the unlocking is completed by rotating the unlocking handle. The lock core is protected by the shell, that is to say, the weakest lock core and the pins on the lock are protected, and the lock core and the pins cannot be damaged by external force. The external force wants to open by force and can only rotate the handle of unblanking, and the handle of unblanking is locked by the lock core set bar on the lock core, and the lock core set bar is not restricted by lock core structure and key structure, and volume and intensity are all bigger, and the intensity of lock core set bar is greater than the intensity of handle of unblanking, therefore want to open by rotating the handle of unblanking by force often, the handle of unblanking will at first protectively initiatively break, and lock core set bar still keeps the locking to the handle of unblanking, and the lock still can not be opened. Therefore, the mechanical damping time-limiting lock without the need of rotating the key has stronger capacity of preventing the damage of violence means.

The invention patent of the patent publication No. CN101463675B, composite spring type poking-proof lock without key rotation, also adopts a similar technical scheme of lock core fixing, but it is different from the present invention: 1. the comparison file is a U-shaped lock, but the invention is an anti-theft door lock, and the technical field is different; 2. the invention adopts a two-stage locking technical scheme that a lock cylinder lock bolt on a lock cylinder locks an unlocking handle and a marble on the lock cylinder locks the lock cylinder, and compared with the technical scheme that an unlocking handle or similar technical characteristics are not available in a comparison document, the two-stage locking technical scheme is obviously different from the two-stage locking technical scheme; 3. the invention has mechanical damping time-limiting unlocking technology.

In a second aspect, a lock designed to be fine and precise is at risk of being opened technically, provided that it is long enough. In reality, lawless persons have strong unlocking technology, and technical unlocking can be realized by a certain tool under the condition of not damaging the lockset. The principle of technical unlocking is that factors such as machining precision errors of the lock are utilized, all the marbles cannot be stressed simultaneously in a locking state, a tool is utilized to dial different sensed resistance of each marble and sound generated when a lock core slightly moves in unlocking, the position of each marble is adjusted to an unlocking position one by one, and technical unlocking is achieved, but the process needs a long time. The mechanical damping time-limited lock without the need of rotating the key achieves the purpose of time-limited unlocking by utilizing the mechanical characteristics of non-Newtonian fluid and the slow rebound hysteresis effect of the mechanical damping device. The overtime lock is unlocked when a key is inserted, then the mechanical damping device controls the overtime slow rebound, the time of the overtime slow rebound is the limited unlocking time of the invention, if the unlocking is not finished before the mechanical damping device slowly rebounds, the overtime lock of the anti-theft lock can be automatically locked, and thus the unlocking can not be realized even if the position of a marble is regulated by a lawbreaker. The slow rebound time of the mechanical damping device is generally less than a few seconds, and the adjustment of the positions of all the marbles in such a short time is almost impossible, so that the mechanical damping time-limiting lock without a key has strong technical unlocking prevention capability.

The invention patent of the publication No. CN105370103A, namely a door lock unlocked in limited time, and the invention patent of the publication No. CN102191884A, namely an advanced anti-theft door lock unlocked in limited time and free of false alarm, relate to the technology of unlocking in limited time, but the limited time control system adopts an electric control system, so that the defect of failure in power failure exists, and the invention is essentially different from the mechanical damping limited time system.

Disclosure of Invention

The purpose of the invention is: according to the mechanical damping time-limiting lock without rotating the key, the key and the lock cylinder do not need to rotate, so that the anti-theft lock has strong capacity of preventing violent damage; and the lock also has the function of unlocking in a limited time, can be automatically locked and cannot be unlocked after the specified time, and has stronger capacity of preventing technical unlocking.

The invention relates to a mechanical damping time-limiting lock without a rotating key, wherein a key hole slider is arranged in a key hole to seal the key hole, and the position of a marble can not be adjusted from the outside. When the lock is unlocked, a key or other unlocking tools are inserted into the key hole, the key hole sliding block in the key hole is pushed to move, the marble can be exposed, the key hole sliding block drives the mechanical damper to move, and the mechanical damper drives the overtime lock to unlock. If a correct key matched with the lock is inserted, the lock core marble can be immediately unlocked, the lock core bounces to drive the lock core lock bolt to unlock the unlocking handle, and the unlocking handle is twisted to complete the unlocking process; if the inserted correct key which is not matched with the lock is not used, the lock cylinder cannot be bounced immediately, but the overtime lock is slowly rebounded under the action of the overtime lock rebounding spring under the control of the mechanical damper, if the lock cannot be unlocked before rebounding of the damper, the lock cylinder can be locked by the overtime lock, the lock cylinder cannot be bounced even if the position of the lock cylinder marble is adjusted, the lock cylinder lock bolt still locks the unlocking handle, the unlocking handle cannot rotate, and therefore the lock cannot be unlocked. When the lock is unlocked, a key or an unlocking tool needs to be pulled out, the key hole sliding block rebounds to the initial position, the key is inserted again, the marble position is adjusted before the overtime lock rebounds and locks, the lock cylinder bounces, the unlocking handle is unlocked, and otherwise the lock cylinder can be continuously locked by the overtime lock.

The invention is characterized in that:

1. according to the mechanical damping time-limited lock, the lock core and the key do not need to rotate, so that the lock core can be positioned in the door plate, only the hole slightly larger than the cross section of the key is reserved on the door plate, and the key is inserted into the key hole of the lock core through the hole in the door plate to realize unlocking. Therefore, if a lawbreaker wants to insert a tool similar to a key into the lock cylinder to forcibly rotate, the unlocking tool is firstly twisted off by the thick door plate, and even if the lawbreaker can twist by using the similar tool, the lawbreaker only destroys the key hole of the lock body, the lock cylinder part still cannot be influenced, and the lock cylinder still cannot be unlocked.

2. According to the mechanical damping time-limiting lock without rotating the key, the key and the lock cylinder do not need to rotate, so that the lock cylinder can be designed to be larger, and more marbles can be arranged. The quantity of the marbles is increased, more time is spent for realizing technical unlocking by adjusting the positions of the marbles, the difficulty is higher for lawless persons, the risk of unlocking and stealing is higher, and the anti-theft performance of the lock is higher. In addition, the number of the marbles is increased, and the key arrangement combination forms are increased, for example, as shown in the figure 16: 4 key marble length combinations are the same, 5 marbles are provided, the combination form of the key is 4, the power of 5 is 1024 combinations, and the repeated situation is easy to occur; 15 marbles, the 15 power of combination form 4 is 1073741824 combinations, and more than 10 hundred million combinations are almost impossible to repeat. The quantity of marbles is increased, and the quantity of key combinations is exponentially increased. The number of the keys is large, the condition that the keys are mutually opened can be reduced, and the anti-theft performance of the lock is improved.

3. The invention relates to a mechanical damping time-limiting lock without a rotating key, 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-shaped damper, a double-gear damper and a single-gear damper, and 3 forms of the damper are specifically introduced as follows:

the damper is a barrel-shaped damper, as shown in fig. 3, and includes a damper housing, a driving shaft, a piston disposed on the driving shaft, and the like, and a damping medium is disposed in a piston cavity formed by the damper housing and the piston, and the damping medium is a non-newtonian fluid, oil, air, elastic particles, and other substances used in the existing damper technology, and therefore, will not be described in detail in this specification (hereinafter referred to as damping medium). When the driving shaft moves fast, the damping medium inside cannot flow out in time or pressure can be transmitted to the damper shell due to the non-Newtonian fluid mechanics property 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. As shown in fig. 1, when a key or an unlocking tool or any other object enters the keyhole, the keyhole slider is pushed to move, and then drives the damper driving shaft to move, or the keyhole slider and the damper driving shaft are integrated (i.e. the damper driving shaft is located in the keyhole to play a role in closing the keyhole and moving along with the key, and the keyhole slider is the damper driving shaft). Because damping force exists between the key hole sliding block and the shell, the damper shell can move along with the driving shaft and the key, the damper shell is separated from the overtime lock bolt, and the overtime lock is unlocked. 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 overtime lock spring, the 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 the damping force, and the short rebound time is the time-limited unlocking time of the invention. The damper shell rebounds and resets, the damper can be contacted with the overtime lock, and pushes the overtime lock bolt to be inserted into the overtime lock bolt inserting groove on the lock cylinder lock bolt, the lock cylinder is locked, and the lock cannot be unlocked. At the moment, if the inserted key is the correct key matched with the lock, the lock cylinder can be immediately bounced under the action of the lock cylinder spring, the lock cylinder lock plunger releases the locking of the unlocking handle, and the unlocking handle can rotate to complete unlocking.

The damper is a double gear damper, as shown in fig. 7, and comprises: the damper comprises a large gear, a small gear and the like, wherein a sealing cavity is formed between the large gear and the small gear, and parts of the large gear and the small gear, which are positioned in the sealing cavity, are respectively provided with non-smooth structures such as blades or protrusions and the like for improving the force transmission efficiency. 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. 6, a rack is arranged on the keyhole slider and meshed with one gear on the damper, and a rack is also arranged on the overtime lock latch and 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 overtime lock bolt is driven to move, and the lock of the overtime lock on the lock core is released. Similarly, after the key is inserted to the bottom, the keyhole sliding block can not move any more, at the moment, the overtime lock bolt can rebound to the original direction under the action of the overtime lock spring, because the damping force exists between the two gears, the rebound process is carried out slowly, and the short rebound time is the time-limited unlocking time of the invention.

The damper is a single gear damper, as shown in fig. 9, and includes a housing, a gear, a shaft, etc., where the gear is disposed on any one of the housing and the shaft, the housing and the shaft form a sealed cavity, and 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 since the damping medium uses a non-newtonian fluid, an oil, air, elastic particles, etc. of the existing damper technology, it is not specifically described in this specification (hereinafter referred to as a damping medium). The shaft and housing also form a fluid coupling-like structure. As shown in fig. 8, the gear is arranged on the housing, the shaft is fixedly arranged on the overtime lock sliding block and can not rotate, the single-gear damper is arranged on the overtime lock sliding block, the shaft of the single-gear damper can not rotate and is fixedly arranged on the overtime lock sliding block, 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, the key hole sliding block can drive the overtime lock sliding block to move under the action of the damping force, the overtime lock sliding block moves to remove extrusion on the overtime lock, the overtime lock plunger moves under the action of the overtime lock plunger separating spring, and the lock of the overtime lock on the lock core is removed. Similarly, after the key is inserted to the bottom, the keyhole sliding block can not move any more, at the moment, the overtime lock sliding block can rebound to the original direction under the action of the overtime lock spring, because of the existence of damping force between the shaft and the gear, the rebound process is carried out slowly, and the short rebound time is the time-limited unlocking time of the invention. In addition, it should be noted that the single gear damper refers to only one gear on the damper, and is different from the double gear damper, and not only one single gear damper can be arranged in one lock, but a plurality of single gear dampers can be arranged in the mechanical damping time-limiting lock without a rotating key according to actual needs.

4. According to the mechanical damping time-limited lock without the need of rotating the key, the overtime lock and the key hole sliding block are flexibly connected through the damper and are not rigidly connected. When the lock is unlocked, a key is required to be inserted at a higher speed, the overtime lock can be released only by pushing the keyhole slide block to move, the inserting speed of the key is higher, because of the mechanical property of non-Newtonian fluid, the shearing stress of the key is higher, the damping force of the damper is higher, the relative displacement of the damper is smaller, the time required by the rebound of the damper is longer, and the limited time of unlocking is also relatively longer; 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, and the overtime lock can not be unlocked 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 overtime lock can not be unlocked, the lock can be kept in a locked state all the time, and the lawless persons can not unlock the lock. Therefore, the invention has stronger anti-theft performance.

5. The invention relates to a mechanical damping time-limiting lock without a key, which is characterized in that a key hole sliding block similar to the cross section of the key is arranged in a lock hole of a lock cylinder as shown in figure 4, the key hole sliding block is connected with a damper or is connected with the damper through structures such as racks, and the damper is connected with an overtime lock or can be contacted with the overtime lock. As shown in the left figure 1 of the attached figure 4, the keyhole slide block is approximately T-shaped and is positioned in the keyhole, the keyhole is closed after the complete reset, and the marble cannot be seen from the outside; or as shown in the left 2 of the attached figure 4, the keyhole slide block is cylindrical and is positioned in the keyhole, the keyhole is closed after the complete reset, and the pin tumbler is abutted against the keyhole slide block, so that the position of the pin tumbler cannot be adjusted from the outside. 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 damper to move or rotate, and the damper drives the overtime lock to unlock temporarily. If the correct key matched with the lock is inserted, the lock core can be bounced at one moment to complete the unlocking process; if the inserted correct key matched with the lock is the other unlocking tool, the lock cylinder cannot bounce in a short time, the overtime lock can slowly rebound and lock under the action of the return spring, the lock cylinder is locked by the overtime lock, and the lock cannot be opened to achieve the time-limited function.

6. According to the mechanical damping time-limiting lock without a key, as shown in the attached figure 5, the lock cylinder is connected with the outside only through the lock cylinder button, the lock cylinder button is not fixedly connected with the lock cylinder, and the lock cylinder can be locked only by pressing the lock cylinder button to press the lock cylinder when the lock is used. When the lock cylinder button is pulled, the lock cylinder button is separated from the lock cylinder, the pulling force cannot be transmitted to the lock cylinder, and the lock cylinder cannot be pulled to realize unlocking, so that the lock cylinder of the anti-theft lock has stronger anti-destructive property. Meanwhile, in order to prevent lawless persons from colliding and pressing the lock cylinder button, force is transmitted to the lock cylinder through the lock cylinder button, the marble is cut off, and the lock cylinder is damaged. The anti-theft lock can also use any one of the following anti-collision technologies on the lock core button and the lock core to protect the lock core and the marble: 1. When the lock core is pressed by the lock core button to be locked, the lock core button is pressed to be in contact with the lock body, namely if the lock core button is pressed again, the pressure can be borne by the lock body, the pressure cannot be applied to the lock core, and the lock core and the marbles cannot be damaged; 2. when the lock core is pressed by the lock core button to be locked, the lower part of the lock core can be contacted with the lock body, namely if the lock core button is pressed again, the pressure is transmitted to the lock body by the lock core, the lock body bears the pressure and the impact, the marble is not stressed, and the lock core and the marble cannot be damaged; 3. when the lock is locked, the bottom of the lock cylinder lock bolt is tightly contacted with the unlocking handle, namely if the lock cylinder button is pressed again, the pressure is transmitted to the unlocking handle and the door plate through the lock cylinder lock bolt, and the door plate bears the pressure and the impact; 4. the lock cylinder lock bolt can be designed into a T shape or an inverted cone shape with a large upper part and a small lower part, so that the pressure impacting the button of the lock cylinder is transmitted to the lock body through the lock cylinder lock bolt without damaging the lock cylinder and the marble. Any one or more of the 4 protection modes can protect the lock core and the marble from being damaged, and the invention strengthens the protection of the most precise and fragile lock core and marble of the lock, so that the invention has stronger capacity of preventing violent damage.

7. According to the mechanical damping time-limiting lock without a key, the key hole sliding block is provided with an anti-collision design, 1, as shown in fig. 4, the upper part of the key hole sliding block is provided with a T-shaped protrusion, when a lawless person uses other unlocking tools to collide and damage the key hole sliding block, the T-shaped protrusion on the upper part of the key hole sliding block is contacted with the lock body, and the impact force is borne by the lock body; 2. When a correct matched key is inserted for unlocking, the lower part of the key hole sliding block can be moved to be close to the lock body, when a lawbreaker uses other unlocking tools to collide and damage the key hole sliding block, the lower part of the key hole sliding block can be contacted with the lock body, and the impact force is borne by the lock body.

8. The mechanical damping time-limiting lock without the need of rotating the key has stronger capacity of preventing technical unlocking. The principle of technical unlocking is that factors such as machining precision errors of the lock are utilized, all the marbles cannot be stressed simultaneously in a locking state, and a tool is utilized to dial different sensed resistance of each marble and sound generated when a lock core slightly moves during unlocking, so that the position of each marble is adjusted to an unlocking position one by one, and technical unlocking is realized. According to the mechanical damping time-limited lock without a key, after the lock core is locked by the overtime lock, all the marbles on the lock core are not stressed, and therefore, the lock core cannot move and cannot make a sound even if the positions of the marbles are adjusted, and whether the positions of the marbles are adjusted or not cannot 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 overtime lock if the correct key cannot be copied, and the unlocking can not be completed if the lock is locked beyond the limited time. The key or the unlocking tool must be pulled out, the damper is completely reset after the keyhole slide block rebounds, the matched correct key is inserted again, and the unlocking is completed before the damper rebounds (namely within the unlocking limited time).

Detailed Description

The mechanical damping time-limiting lock without a rotary key is described in detail in the following with the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

A mechanical damping time-limiting lock cylinder damper type without a rotating key. As shown in the attached figure 1, the mechanical damping time-limiting lock without the rotating key of the invention comprises: the lock body 2, the lock core 1, the marble 14, the lock core button 17, the lock core lock bolt 16, the unlocking handle 8 and the key hole sliding block 3 are composed of a driving shaft of a barrel-shaped damper, namely the driving shaft of the damper is the key hole sliding block 3, a key hole sliding block spring 7, the damper 5 and the overtime lock 4. The lock core 1 is arranged on the lock body 2, and the lock core and the lock body are provided with marbles 14 (common atomic marbles are selected in the embodiment, and most marbles in the prior art, including atomic marbles, compound marbles and the like, can be used for the marbles of the invention). The lock core spring 15 is arranged between the lock core and the lock body, the lock core can be bounced along the axial direction under the action of the lock core spring to unlock the unlocking handle 8 by the lock core lock bolt 16, the lock core button 17 and the lock core lock bolt 16 are respectively arranged at two ends of the lock core, and the lock core lock bolt is provided with an overtime lock bolt slot.

The lock body 2 is provided with a key hole 31, a key hole slider 3 is arranged in the key hole 31, a key hole slider spring 7 is arranged between the key hole slider 3 and the lock body 2, the key hole slider is connected with a damper 5, a damper shell 51 is contacted with the overtime lock 4, the overtime lock bolt is extruded into an overtime lock bolt slot on the lock cylinder bolt 16, and the overtime lock locks the lock cylinder bolt, so that the lock cylinder cannot be bounced, namely cannot be unlocked.

The unlocking handle 8 is connected with other mechanisms of the lock (the other mechanisms of the lock use the existing door lock technology, are not technical innovation of the invention, and therefore are not specifically described in the specification), the unlocking handle is rotated for unlocking, and the unlocking handle is provided with a lock cylinder lock bolt slot, and the lock cylinder lock bolt is inserted into the slot for locking the unlocking handle.

As shown in fig. 3, the damper is a barrel-shaped damper, and includes a damper housing 51, a driving shaft, i.e., a keyhole slider 3, a piston 52 disposed on the driving shaft, and a damping fluid hole 53 disposed on the piston, and air is disposed in a piston cavity 54 formed by the housing and the piston as a damping medium.

As shown in fig. 10, when a proper key is inserted into the key hole, the key hole slider 3 is pushed to move, the key hole slider drives the piston 52 to move, when the moving speed acting on the piston 52 is high, the damping medium in the piston cavity cannot flow out through the damping fluid hole 53 on the piston in time, the pressure is transmitted to the damper shell, the damper shell moves along with the driving shaft and the key, the damper shell is separated from the overtime lock plunger, and the overtime lock is unlocked. When the moving speed is high or low, damping media and the like in the damper can flow out through the damping liquid hole to absorb pressure, and the damper shell can keep static and only the key hole slide block moves. After the key is inserted to the bottom, the key can not move the key hole slide block and can not move any more, at the moment, the damper shell can rebound to the original direction under the action of the overtime lock spring, the damping liquid in the piston cavity flows into the other piston cavity through the damping liquid hole 53, the rebound process is slow due to the existence of the damping force, and the short rebound time is the time-limited unlocking time of the invention. The damper housing rebounds back and returns back and the damper housing 51 will contact the overtime lock 4 and push the overtime lock bolt to insert into the overtime lock bolt slot on the lock cylinder bolt 16, locking the lock cylinder and making it impossible to unlock the lock. At the moment, if the inserted key is the correct key matched with the lock, the lock cylinder can be immediately bounced under the action of the lock cylinder spring, the lock cylinder lock plunger releases the locking of the unlocking handle, and the unlocking handle can rotate to complete unlocking.

As shown in fig. 11, if a key is not inserted, the lock cylinder cannot bounce within a limited unlocking time, and the lock cylinder is locked back after time passes, and then even if the positions of the pins are adjusted correctly, the lock cylinder cannot bounce, and the lock cylinder lock bolt still locks the unlocking handle and cannot unlock.

Example 2

A mechanical damping time-limiting lock double gear damper type without a rotating key. The damper in this embodiment is a double gear damper, and the specific structure thereof includes as shown in fig. 7: a large gear 57, a small gear 56 and the like, wherein a sealed cavity is arranged between the large gear and the small gear, blades 55 are respectively arranged on the parts of the large gear and the small gear which are positioned in the sealed cavity, and non-Newtonian fluid type silicon oil is arranged in the sealed cavity as a damping medium.

As shown in fig. 12, when a correct key is inserted into the key hole, the key hole slider 3 is pushed to move, and then the key hole slider drives the small gear 56 of the damper to rotate, because damping force exists between the two gears on the damper, the large gear 57 also rotates, so that the overtime lock 4 is driven to move, and the lock of the lock cylinder by the overtime lock is released. The lock core springs up rapidly under the effect of lock core spring, releases the locking to the handle of unblanking, and the handle of unblanking can be unblanked to the rotation.

As shown in fig. 13, if a key is not inserted, the lock cylinder cannot bounce within a limited unlocking time, and the lock cylinder is locked back after time passes, and then even if the positions of the pins are adjusted correctly, the lock cylinder cannot bounce, and the lock cylinder lock bolt still locks the unlocking handle and cannot unlock.

The difference of this embodiment compared with embodiment 1 is also shown in fig. 6, the unlocking handle 8 is changed from the traditional handle shape to the knob shape; when the lock core is pressed and locked by the lock core button 17, the lock core button is pressed to be in contact with the lock body, namely if the lock core button is pressed again, the pressure can be borne by the lock body and can not act on the lock core, so that the lock core and the marble are protected; the keyhole slider spring is changed from a compression type to a tension type. The above differences are all based on the simple changes and substitutions of the claims and the specification of the present invention, and all belong to the protection scope of the present invention.

Example 3

A mechanical damping time-limited lock single gear damper type without a rotating key. The damper in this embodiment is a single-gear damper, and the specific structure thereof includes as shown in fig. 9: gear 58, housing 51 and shaft 59. The gear is shown arranged in one piece on a housing, which housing and shaft are provided with vanes 55 in the part of the formed sealed chamber, respectively, in which non-newtonian fluid and elastomeric particulate crop damping medium are arranged.
