Description

Technical Field

[0001] This invention belongs to the field of access control technology, specifically relating to an access control device for building security management. Background Technology

[0002] Fixed closing devices used at openings in buildings and structures typically open and close by rotating one side of the device around an axis. Currently, when installing a closing body on a building, the rotation direction of the closing body must first be determined according to the building's design. Once the closing body is installed, it can only be opened by rotating around an axis from one side. Traditional closing bodies cannot achieve this when special circumstances require opening from the other side. Summary of the Invention

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figure 1-16 As shown:

[0046] A building security management access control device includes a closing body 4, a cooperating frame 5, and an access control closing assembly 1. The closing body 4 includes a rotating housing 417 and a locking rod 418. The cooperating frame 5 includes a receiving groove 51 and a locking groove 511. The rotating housing 417 is slidably connected to the inner side of the closing body 4. The locking rod 418 is slidably connected to the inner side of the rotating housing 417. The receiving groove 51 is provided on the inner side of the cooperating frame 5 at a position opposite to the rotating housing 417. The locking groove 511, which communicates with the receiving groove 51, is also provided on the inner side of the cooperating frame 5. The locking groove 511 can cooperate with the locking rod 418.

[0047] In an optional embodiment, the closing body 4 further includes a control rod 41, a limiting rod 411, a limiting hole 412, a sliding housing 413, a sliding block 414, a second compression spring 415, a trapezoidal block 416, a limiting ring 419, and a third compression spring 4191. The control rod 41 is slidably connected to the inner side of one end of the closing body 4, and the limiting rod 411 is slidably connected to the inner side of one end of the control rod 41. The inner side of the closing body 4 also has two limiting holes 412 that can cooperate with the limiting rod 411. Both ends of the control rod 41 are fixedly connected to the sliding housing 413, and a sliding block 414 is fixedly connected to the outer side of one end of the sliding housing 413. The movable locking block 414, the sliding housing 413, and the sliding locking block 414 are all slidably connected to the inner side of the closed body 4. The left and right ends of the control rod 41 are fixedly connected to trapezoidal blocks 416. A second compression spring 415 is fixedly connected between the outer side of one end of the trapezoidal block 416 and the inner side of one end of the sliding housing 413. A rotating housing 417 is fixedly connected to the outer side of one end of the sliding housing 413. The upper and lower ends of the rotating housing 417 are slidably connected to locking rods 418. A limit ring 419 is fixedly connected to one end of the locking rod 418. A third compression spring 4191 is fixedly connected between the outer side of one end of the limit ring 419 and the inner side of one end of the rotating housing 417.

[0048] In this embodiment: the closing body 4 can be a door body or a window body, and the cooperating frame 5 can be a door frame or a window frame. When moving the control rod 41, the limiting rod 411 first needs to be pulled out of the limiting hole 412, but the limiting rod 411 should not be separated from the control rod 41. At this time, the limiting rod 411 can drive the control rod 41 to move. Taking the control rod 41 moving from the right to the left as an example, the limiting rod 411 is separated from the limiting hole 412 on the right side. After moving the control rod 41 to the left, the limiting rod 411 is inserted into the limiting hole 412 on the left side, so that the control rod 41 can be stably fixed in this position after moving and will not move arbitrarily. The movement of the control rod 41 will drive the sliding housings 413 on the left and right sides to move. When the body 413 moves, it will also be affected by the sliding block 414. The sliding block 414 can limit the movement of the sliding housing 413. The movement of both sliding housings 413 will drive the rotating housing 417 to move. Both rotating housings 417 will move from right to left. The rotating housing 417 on the right will separate from the receiving groove 51 on the right side of the mating frame 5 and move towards the inside of the closed body 4 until the rotating housing 417 is completely inside the closed body 4. At the same time, the rotating housing 417 on the left will move out of the closed body 4 and enter the receiving groove 51 on the left side of the mating frame 5. Thus, the closed body 4, which was originally connected through the right side of the mating frame 5, is now connected through the left side of the mating frame 5.

[0049] In the operation where the control rod 41 drives the two sliding housings 413 to move, taking the movement of the control rod 41 from right to left as an example, assuming that the right rotating housing 417 is still on the right side of the mating frame 5, while the left rotating housing 417 is on the inner left side of the closed body 4, when the control rod 41 moves from right to left, the control rod 41 will drive the right trapezoidal block 416 to move. The movement of the right trapezoidal block 416 will overcome the elastic force of the second compression spring 415. Since the locking rod 418 on the inner side of the rotating housing 417 is engaged with the locking groove 511, the rotating housing 417 cannot move at this time. The inability of the right rotating housing 417 to move will lead to the right side... The sliding housing 413 also cannot move. At this time, although the second compression spring 415 on the right is compressed, it will not cause the sliding housing 413 on the right to move. When the trapezoidal block 416 on the right moves completely away from the locking rod 418, the third compression spring 4191 on the right can drive the two limiting rings 419 on the right to move towards each other. Thus, the limiting rings 419 drive the two locking rods 418 to move towards each other, so that the two locking rods 418 on the right disengage from the locking groove 511 on the right and completely enter the inner side of the rotating housing 417 on the right. At the same time, when the control rod 41 moves from right to left, the following sliding housing 413, sliding block 414, trapezoidal block 416, and rotating housing 417 move away from each other. 17. The locking rod 418, limit ring 419, third compression spring 4191, receiving groove 51, and locking groove 511 all specifically refer to the left side. The control rod 41 will push the trapezoidal block 416 to move to the left. The leftward movement of the trapezoidal block 416 will drive the second compression spring 415, thereby driving the sliding housing 413 to move. The movement of the sliding housing 413 will drive the rotating housing 417 to move, causing the rotating housing 417 to enter the inner side of the receiving groove 51. When the leftward movement of the sliding housing 413 is restricted by the sliding block 414 and cannot move, the rotating housing 417 will drive the locking rod 418 to be in the position corresponding to the locking groove 511. At this time, the control rod 41 will still continue to move to the left. Moving the trapezoidal block 416 further will cause the second compression spring 415 to be stretched. The trapezoidal block 416 will continue to move to the left and contact the locking rod 418. The inclined surface of the trapezoidal block 416 will push the two locking rods 418 to move in opposite directions, so that the trapezoidal block 416 moves and drives the limiting ring 419 to overcome the elastic force of the third compression spring 4191 and move to extend to the outside of the rotating housing 417 until the locking rod 418 moves and engages with the locking groove 511. This completes the disengagement of the locking rod 418 on the right side of the closed body 4 from the mating frame 5, while the locking rod 418 on the left side of the closed body 4 engages with the mating frame 5, thus changing the original opening from the right side to the left side of the closed body 4.

[0051] In an optional embodiment, the access control closure assembly 1 includes an access control component 2, which includes a key 21, a friction ring 211, a string 212, a vibrating tube 213, and a conductive sheet 214. One end of the key 21 is provided with a friction ring 211 with a different coefficient of friction. The friction ring 211 can generate vibration by sliding friction with the string 212. A conductive liquid with a uniform flow rate is introduced into the inner side of the vibrating tube 213. After the vibration of the string 212 is transmitted to the vibrating tube 213, it can cause the conductive liquid discharged from the vibrating tube 213 to change its trajectory according to the vibration frequency. The conductive liquid with the changed trajectory can contact the two conductive sheets 214 that are close to each other in a fixed and changing pattern.

[0059] In this embodiment: Fixed closing devices used at openings of buildings or similar structures generally have anti-theft functions. Traditional closing devices are mainly opened by key 21, fingerprint, magnetic card, etc. Generally speaking, a closing device can be opened by different fingerprints or magnetic cards. For a closing device opened by key 21, there can be multiple keys 21, but all keys 21 are the same. Through reverse engineering, traditional closing devices have corresponding cracking methods. As cracking methods are continuously developed, the security of traditional closing devices gradually decreases.

[0060] The access control closure assembly 1 is a completely new unlocking method that is difficult to crack using traditional methods, thus improving security. The access control closure assembly 1 unlocks by changing the shape of the water flow through vibration. The shape change of the water flow is dynamic and needs to be changed in a time sequence, thus increasing the difficulty of cracking. By combining physical and electronic methods, it cannot be cracked by either physical or electronic means alone. Furthermore, it abandons the traditional solid-state physical method for encryption and instead uses a combination of variable non-solid-state physical and electronic methods for encryption. Without the key 21, the variable physical method cannot be copied, thus increasing security.

[0061] When the access control closing assembly 1 is installed on the door, and the door needs to be unlocked using the key 21, the key 21 must first be inserted into the inner side of the inner lock tube 22. When the key 21 is inserted into the inner side of the inner lock tube 22, it will first contact the limit head 311, aligning the long locking strip 325 on the key 21 with the slot 321. This allows the mating pin 324 to be inserted into the inner side of the inner rotating block 32, so that the inner wall of the inner rotating block 32 contacts the outer end face of the mating pin 324. At this time, the long locking strip 325 passes through the slot 321 and then the key 21 is turned. The key 21 will drive the partition 323, which will drive the mating pin 324 to rotate. The rotation of the mating pin 324 will drive the long locking strip 325 to rotate. Since the long locking strip 325 has already passed through the inner rotating block 32 and is not in contact with the inner rotating block, the key 21 is now in contact with the inner rotating block 32. At point 32, the long locking bar 325 can rotate and contact the inner rotating block 32 through the partition 323, thus preventing the key 21 from directly contacting the limiting head 311 and reducing friction. After rotating a certain angle, the long locking bar 325 will contact the limiting post 322. Continuing to rotate the long locking bar 325 will drive the limiting post 322 to rotate as well. The rotation of the limiting post 322 will drive the inner rotating block 32 to rotate, which will pull the pull cable 33. After being pulled, the pull cable 33 will pull the locking post 331 to move, causing the two locking posts 331 to move towards each other. The movement of the locking posts 331 will drive the spring seat 334 to move against the elastic force of the first compression spring 335, ultimately causing the locking posts 331 to move and separate from the inner locking tube 22, thus preventing contact. The limiting head 311 can move, at which point the elastic force of the first tension spring 312 can be released. The first tension spring 312 will drive the limiting head 311 to move. During the movement of the limiting head 311, it will drive the locking post 331 to move together. Due to the influence of the elastic force of the first compression spring 335, the locking post 331 will move tightly against the inner wall of the inner locking tube 22 during the movement. In order to reduce the sliding resistance between the inner locking tube 22 and the locking post 331, a steel ball 332 that can rotate inside is embedded in the inner side of the top of the locking post 331. Through the rolling of the steel ball 332, the resistance between the locking post 331 and the inner locking tube 22 can be reduced. The movement of the limiting head 311 will drive the inner rotating block 32, thereby driving the long locking strip 325 to move. When the long locking strip 325 moves, it drives the mating post 324, which in turn moves the partition 323. The partition 323 then moves the key 21. Furthermore, the limiting head 311 also moves the movable tube 31. Since one end of the movable tube 31 is closed and sealed, while the other end is open, a fixed tube 313 is slidably sealed inside the opening of the movable tube 31. A small through hole 314 is provided on the fixed tube 313. Therefore, when the movable tube 31 moves, the air inside the movable tube 31 needs to be expelled through the small through hole 314 to allow the movable tube 31 to move relative to the fixed tube 313. However, the air expulsion speed through the small through hole 314 is limited. Therefore, when the movable tube 31 moves due to the elastic force of the first tension spring 312…The moving speed of the movable tube 31 is more stable, and the time required for the movable tube 31 to reach its maximum stroke is also basically consistent. Therefore, the time it takes for the key 21 to move inside the inner locking tube 22 each time is also basically consistent. Due to the influence of the elastic force of the first tension spring 312, although the moving speed of the key 21 inside the inner locking tube 22 cannot be absolutely uniform, the speed change pattern of the key 21 is basically consistent each time.

[0062] After the key 21 moves inside the inner locking tube 22, it drives the friction ring 211 into the inner side of the inner locking tube 22, where it comes into contact with the string 212. The friction ring 211 can be a single piece, but the coefficient of friction can vary at different positions on its upper side. Alternatively, it can be composed of multiple friction rings 211 of different lengths, the same diameter, and different coefficients of friction. After the friction ring 211 rubs against the string 212, the string 212 will vibrate at different frequencies due to partial sliding contact with the friction ring 211 at different coefficients of friction. The vibrations of the string 212 at different frequencies are transmitted to the panel 222 through the connecting post 224. The two panels 222 are connected and fixed by a rigid side panel 221, creating a hollow space between the upper and lower panels 222. Vibration between the two lower panels 222 can be transmitted through the air in the hollow section, avoiding vibration transmission loss caused by the connecting column 224 and the conductive plate 225 being connected to the same panel 222. The vibration of the lower panel 222 will drive the conductive plate 225 to vibrate, and the vibration of the conductive plate 225 will drive the vibration tube 213 to vibrate. Before this, conductive liquid should be pre-filled inside the circulation housing 23. The amount of conductive liquid inside the circulation housing 23 should not be excessive, so as not to obstruct the conductive liquid sprayed from the vibration tube 213. Then, the water pump 232 is energized. After the water pump 232 is energized, it will draw out the conductive liquid inside the circulation housing 23 and then enter the inside of the vibration tube 213 through the circulation water pipe 231 and then through the flexible connecting ring 233, so that the conductive liquid flows from the vibration tube 213. The liquid ejected from the inner side of the vibrating tube 213 is better vibrated by the flexible connecting ring 233. Under the vibration of the vibrating tube 213, the liquid ejected from the vibrating tube 213 will change shape, and different shapes will be formed at different frequencies. When the vibrating tube 213 is not vibrating, the ejected liquid is parabolic or straight. When the vibrating tube 213 vibrates at a certain frequency, the ejected liquid can take on various shapes, such as wave shape and spiral shape. As the frequency changes, the conductive liquid will also change. The conductive liquid with the changed shape will come into contact with the conductive sheet 214. That is, the parabolic or straight liquid cannot come into contact with the conductive sheet 214, but the tip of the spiral shape will come into contact with the conductive sheet 214. Because the two conductive sheets 214 are mutually The conductive sheets 214 are arranged in groups of close proximity and at equal intervals. Therefore, when the deformed conductive liquid comes into contact with a group of conductive sheets 214, two conductive sheets 214 in that group will become electrically connected. This electrical connection generates an electrical signal. As the vibration frequency changes, the shape of the liquid also changes. The changing liquid will come into contact with different conductive sheets 214, thus generating different electrical signals. The continuously changing electrical signal will change over time, and its generation and disappearance will exhibit a fixed variation over time. When the pattern of this electrical signal change matches the pre-set data in the access control closing assembly 1, the unlocking operation can be performed, and the access control closing assembly 1 can open the mechanical lock.The access control closure assembly 1 can open the mechanical lock by energizing the motor in an existing smart mechanical lock, thereby driving the mechanical lock open. Alternatively, it can be opened in other ways. The access control closure assembly 1 in this invention only concerns how to match it with the key 21. The access control closure assembly 1 can be unlocked using different keys 21; that is, the friction coefficient arrangement of the friction rings 211 on different keys 21 can be different, as long as the electrical signal generated by unlocking with the key 21 can successfully match the preset data in the access control closure assembly 1.

[0063] As can be seen from the above working principle, when key 21 is inserted into the inner side of the access control closing assembly 1, with the help of auxiliary component 3, key 21 can move at a constant speed after being inserted into the inner lock tube 22. The moving speed of key 21 does not need to be absolutely constant, but the speed change should be the same each time. Only when the speed change of key 21 is the same each time can it be identified. It should be understood that if the moving speed of key 21 changes, even if it is the same key 21, the generated electrical signal will change.

[0064] Because the bottom of the conductive sheet 214 is designed with a sharp structure, when the liquid no longer actively contacts the conductive sheet 214, it can drip down quickly, thereby quickly disconnecting the conductive sheet 214 and breaking the electrical connection.

[0065] After key 21 successfully unlocks the door, pull key 21 outwards. Key 21 will move the partition 323, which in turn moves the mating post 324. The mating post 324 will move the long locking strip 325, which in turn moves the inner rotating block 32. As the inner rotating block 32 moves towards its initial position, it will move the limiting head 311. When the limiting head 311 reaches its initial position, the position of the engaging post 331 will correspond to the engaging hole 333, allowing the engaging post 331 to move. At this time, the elasticity of the first compression spring 335 can be released. The first compression spring 335 will push the spring seat 334 to move back to its original position. The spring seat 334 will then move the engaging post 331 into the inner side of the engaging hole 333, thereby restricting the position of the limiting head 311 again. During the process of inserting 31 into the engagement hole 333, the movement of the engagement pin 331 will drive the pull wire 33, which in turn will drive the limit head 311 to rotate. Therefore, when the hand that is turning the key 21 feels the reverse force transmitted by the key 21, it can be turned in the same direction to make the key 21 rotate to the initial position. Alternatively, it can be lifted and turned. However, if the key 21 is turned prematurely, it should not be made to make the key 21 drive the long locking strip 325 to engage with the strip groove 321. Otherwise, the key 21 will disengage from the inner rotating block 32, and the limit head 311 will not be able to return to its original position. After the limit head 311 is fixed in its original position by the engagement pin 331, the key 21 can be turned further to make the key 21 rotate and drive the long locking strip 325 to engage with the strip groove 321. Then the key 21 can be pulled out to complete the unlocking operation.

[0066] By installing a filter sponge 315 inside the fixed tube 313, dust inside the fixed tube 313 and the movable tube 31 can be reduced, keeping their insides clean.
