Description
Technical Field
The invention belongs to the technical field of safety locks, and particularly relates to an anti-theft fireproof safety lock body, a fingerprint lock and a door structure.
Background
The existing incompatibility between the prior burglary-resisting door and the fireproof door brings much trouble to the society for selecting products, and causes great waste and economic loss. The door must be theft-proof when the objects are heavy-counted, such as money adding room and equipment room in the bank business place, but the items all suffer from the trouble during fire-fighting inspection. The fireproof door can be opened easily from inside without using any tools such as keys in case of fire, is provided with a sign with a use prompt at a remarkable position, and can be opened manually at the inner side and the outer side of the fireproof door.
The anti-theft safety door is provided with an anti-theft lock, and the anti-theft lock which meets the GA/T73 and GA374 standards is required to be arranged. Among them, GA/T73-2015 in "mechanical anti-theft Lock" requires: "Key-operated locks should not have the function of enabling the main lock tongue to be unlocked without a key after locking. The main lock tongue is locked, and then the lock can be opened only by a key, so that the manual quick opening cannot be realized from the inside.
The biggest conflict points between the current national standard GB17565-2007 general technical Condition for anti-theft safety doors and GB50016-2014 building design fireproof Specification and GB12955-2008 fireproof door are as follows: the collision of door leaf locks on quick opening. When the anti-theft safety door requires the anti-theft lockset to be in an anti-theft state, the inside and outside of the door body are both required to be opened by a key when the main lock tongue stretches out, so that the anti-theft performance is improved; the fireproof door safety door is required to be opened manually and quickly (commonly called as one-key opening) from the inner side of the protection surface of the door body, so that people on the inner side of the protection surface can escape quickly under the condition of fire, and the conflict can be easily solved through structural adjustment.
The current market demands for doors combining fire protection and theft protection. The same protective door in the current market simultaneously passes through the detection method of theft prevention and fire prevention: when an enterprise sends a security door to a security inspection mechanism for anti-theft detection, the lockset is in a complete locking state, quick opening cannot be realized from the inner side of a protection surface, and an anti-theft performance report is obtained in the state; when the fire protection inspection mechanism is sent to conduct fire protection inspection, the door lock is in an incompletely locked state, and a fire protection performance detection report is obtained in the incompletely locked state. That is, the fire-proof and theft-proof performance of the fire-proof and theft-proof door is the result of the door being in two different states respectively. Thus, fire and burglary doors are marketed as such, but are not substantially in compliance with the current relevant standards.
When personnel exist in the house, the fireproof requirement is mainly considered, and the lockset considers a fireproof mode, namely, the lockset can be quickly opened from the inside; when no personnel are in the house, the anti-theft requirement is considered, and the lockset and the locking point are locked. The user suggests a use mode on the premise of comprehensively evaluating the safety risk, and the anti-theft mode can be technically started if personnel exist in the house. Thus, the mess of detaching the fireproof door and installing the burglary-resisting door in the market can be solved.
Most electronic locks can be opened manually and quickly from inside, and meanwhile, after the electronic locks are roasted at high temperature, the electronic locks are easy to melt, and the electronic locks cannot be opened quickly, so that the electronic locks are quite unsafe from the viewpoint of fire safety. Therefore, the lock body structure is improved to solve the problem that the functions of the existing anti-theft door and the existing fireproof door are contradictory, and the lock body is a crucial component for the anti-theft door, so that the lock body with both anti-theft and fireproof functions is required to be provided, and the potential safety hazard of the existing anti-theft door and the existing fireproof door in the current market is fundamentally solved.
However, most lock body devices in the prior art have a single-key single-lock core structure, and aiming at safes for storing important document data or financial objects, the lock body devices are required to have good anti-theft performance, and two people are required to arrive at the scene at the same time for unlocking, so that Chinese patent CN111287584a discloses a novel double-key linkage safe lock and a design method of a lock chip. However, it is mainly used in safe deposit box locks, which are not suitable for door locks, so that it is highly desirable to provide an anti-theft fireproof safety lock body to solve the above problems.

The handle mechanism 7 may cooperate with the first lock cylinder linkage assembly 52 and the second lock cylinder linkage assembly 62 for switching between the locked and unlocked states of the main bolt 2, the first bolt 3, and the oblique bolt 4.
More specifically, the first lock cylinder linkage assembly 52 includes a first sliding vane 521 disposed near the first lock cylinder hole 51, a first shifting plate 523 capable of moving synchronously with the first sliding vane 521, a second sliding vane 522 capable of engaging with the first sliding vane 521 for transmission, a linkage rod 524 capable of moving along the length direction of the housing 1 under the driving of the first shifting plate 523, and a transmission rod 525. The second sliding tooth piece 522 is meshed with the handle mechanism 7 for transmission, and the second sliding tooth piece 522 is connected with the main lock tongue 2 for transmission. One end of the linkage rod 524 is fixedly connected with the handle mechanism 7, the transmission rod 525 is arranged in parallel with the linkage rod 524 up and down, and two ends of the transmission rod 525 are respectively in transmission fit with the handle mechanism 7 and the second lock cylinder linkage assembly 62, so that the first lock tongue 3 of the handle mechanism 7 is switched between a locking state and an unlocking state.
The second lock core linkage assembly 62 comprises a rotating piece 621 arranged close to the second lock core hole 61, a first mounting plate 31 fixedly connected with the first lock tongue 3, a rotating tooth 623 coaxially connected with the rotating piece 621 through a first shaft body 622, and a gear 624 meshed with the rotating tooth 623 for transmission; the first mounting plate 31 is provided with a chute 311 and a travel groove 312, the travel groove 312 extends along the width direction of the housing 1, the chute 311 has a head end close to the first lock cylinder hole 51 and a tail end close to the second lock cylinder hole 61, and the distance between the tail end and the first lock tongue 3 is smaller than the distance between the head end and the first lock tongue 3. The rotating member 621 is rotatably connected to the housing 1 through a first shaft 622, the first shaft 622 protrudes vertically upward from the surface of the rotating member 621, and a first toggle post 625 is further vertically protruded from the side surface of the rotating member 621, the first toggle post 625 may be protruded into the chute 311, and the first shaft 622 may be vertically protruded into the travel slot 312.
When the rotating piece 621 rotates relative to the housing 1, the rotating teeth 623 are driven to rotate together, as shown in fig. 8, so as to realize meshing transmission of the rotating teeth 623 and the gears 624. To achieve a driving engagement of the drive rod 525 and the second lock cylinder linkage assembly 62, the drive rod 525 has a tooth segment 526 thereon, the tooth segment 526 being capable of meshing with the gear 624 for driving.
In order to achieve the function that the second lock core mechanism 6 cannot control the handle mechanism 7 in the reverse direction, the transmission rod 525 is provided with a idle stroke position, specifically in this embodiment, a square hole 527 is formed at one end of the transmission rod 525 near the handle mechanism 7, the length of the square hole 527 is greater than the length of a part of the handle mechanism 7 extending into the square hole 527, and in the unlocking state, the part of the handle mechanism 7 extending into the square hole 527 is a distance from the edge of the square hole 527. So that the drive rod 525 and the handle mechanism 7 are not driven when the second lock cylinder linkage assembly 62 drives the first lock tongue 62 to switch to the locked state.
The first lock tongue 3, the main lock tongue 2 and the inclined lock tongue 4 are sequentially positioned on one side of the shell 1, and a second lock tongue 8 is further arranged at a position close to the inclined lock tongue 4, and the second lock tongue 8 is driven by the transmission component 82 to switch between an locking state and an unlocking state. The transmission assembly 82 comprises a top-bottom rod 821 which can be connected with the main bolt 2 in a transmission way, a special-shaped piece 823 which is connected to the shell 1 in a rotating way through a second shaft 822, a second mounting plate 81 which is connected with the bolt two 8, a driving chute 824 which is arranged at one end of the top-bottom rod 821, which is close to the main bolt 2, a second stirring column 825 which is arranged at one end surface, which is close to the bolt two 8, and a notch 826 which is formed on the special-shaped piece 823 and is used for the second stirring column 825 to stretch in, and a through groove 827 which extends along the length direction of the shell 1, as shown in fig. 7 and 8. A bar-shaped groove 811 for the second shaft 822 to vertically extend and a third toggle post 812 which can downwardly extend into the through groove 827 are formed in the second mounting plate 81, and the bar-shaped groove 811 extends in the width direction of the housing 1.
When the main lock tongue 2 is retracted into the housing 1, the third toggle post 22 connected to the main lock tongue mounting plate 21 is in the driving chute 824, so that the top-bottom rod 821 is driven to move towards the inner side of the housing 1, the top-bottom rod 821 is moved towards the left side close to the main lock tongue 2, the special-shaped piece 823 is driven to rotate anticlockwise, and the third toggle post 812 moves along with the through groove 827, so that the second lock tongue 8 is retracted towards the inner side of the housing 1, namely, the second lock tongue 8 is also switched to the unlocking state.
As shown in fig. 3 and 7, the handle mechanism 7 includes a lower handle pulling piece 71 capable of being meshed with the second sliding tooth piece 522 for transmission, and an upper handle pulling piece 72, where the upper handle pulling piece 72 has a first fin leg 721 and a second fin leg 722, the first fin leg 721 can be fixedly connected with the linkage rod 524, the second fin leg 722 can be in transmission fit with the oblique bolt 4 for driving the oblique bolt 4 to retract into the housing 1, the oblique bolt 4 extends out of the housing 1 and can be driven by a spring, and its specific structure is that the prior art can be realized, and details are not repeated.
The handle mechanism 7 has a handle 75 and a handle hole 73, and as shown in fig. 6, the inner ring of the handle lower blade 71 forms a first inner abutment surface 713 and a second inner abutment surface 714, in other words, the inner ring of the handle lower blade 71 forms at least two abutment surfaces disposed at intervals. When the handle mechanism 7 unlocks the main bolt 2, the first bolt 3 and the inclined bolt 4, the handle hole 73 abuts against the first inner abutting surface 713; when the handle mechanism 7 locks the main lock tongue 2, the first lock tongue 3 and the inclined lock tongue 4, the handle hole 73 abuts against the second inner abutting surface 714; and when the first cylinder linkage assembly 52 drives the main bolt 2 to switch to the locked state, the handle lower plectrum 71 and the handle hole 73 are not driven.
The lock further comprises a counter lock mechanism 9 located between the first lock cylinder hole 51 and the second lock cylinder hole 61, and the counter lock mechanism comprises a counter lock bolt 91 and a counter lock hole 92, and specific functions are realized in the prior art and are not repeated.
In the process of unlocking the main lock tongue 2 by the first lock core mechanism 5, a key extends into the first lock core hole 51 to drive the first sliding tooth piece 521 to rotate clockwise and drive the second sliding tooth piece 522 to rotate anticlockwise, and the main lock tongue mounting plate 21 retracts into the shell 1, so that the main lock tongue 2 retracts into the shell 1, and unlocking of the main lock tongue 2 is realized. At the same time, the top-bottom rod 821 moves to the left side near the main bolt 2, and the special-shaped piece 823 rotates anticlockwise, so that the second bolt 8 moves and retracts into the housing 1, i.e. the second bolt 8 is also switched to the unlocking state. Similarly, when the second sliding tooth 522 rotates counterclockwise, the engaged lower handle shifter 71 rotates clockwise, but at this time, the lower handle shifter 71 only idles in a virtual position between the first inner abutment surface 713 and the second inner abutment surface 714, and does not drive the handle mechanism 7 to rotate, the first lock core mechanism 5 cannot control the movement of the handle mechanism 7 in the opposite direction through the lower handle shifter 71, and each time the first lock core mechanism 5 drives the lower handle shifter 71 to rotate, the virtual position between the first inner abutment surface 713 and the second inner abutment surface 714 is completely removed, so that the next operation of the handle mechanism 7 is exactly in the abutment position with the lower handle shifter 71. When the sliding tooth piece one 521 rotates clockwise, the first shifting piece 523 also rotates clockwise, so that the linkage rod 524 is driven to slide, the upper shifting piece 72 of the handle is pulled to rotate clockwise, the purpose of unlocking the inclined lock tongue 4 is achieved, when unlocking is completed, after external force to the handle mechanism 7 is stopped, the inclined lock tongue 4 can extend out of the shell 1 through the reset spring on the inclined lock tongue 4, and the upper shifting piece 72 of the handle, the linkage rod 524 and the first shifting piece 523 are driven to return to the initial position. The process of switching from the unlocking state to the locking state is opposite and will not be described again.
The process of unlocking the main bolt 2 by the handle mechanism 7 is that the handle hole 73 rotates clockwise to drive the lower handle shifting piece 71 to rotate synchronously and drive the second sliding tooth piece 522 to rotate anticlockwise, the main bolt mounting plate 21 retracts into the shell 1, so that the main bolt 2 retracts into the shell 1, and unlocking of the main bolt 2 is realized.
