Description

Technical Field

[0001] The invention relates to the technical field of locks, in particular to a safe lock body with an emergency key. Background Art

[0002] Safe door locks generally include ordinary pin locks, fingerprint locks and password locks. In order to improve the anti-theft performance, electric locks are more common. Electric locks have been widely used in people's lives. They generally include electronic control module control. When the electronic control module is unlocked, turning the handle can unlock it.

[0003] The existing Chinese patent with publication number CN104631960A discloses an electrically controlled semi-automatic lock including a three-way locking device, including a panel, a shell and an electrically controlled lock body, the electrically controlled lock body including an electronic control module and a bolt limiting mechanism and a locking device electrically connected thereto, a knob is provided on the panel, and the locking device is a three-way locking device, which includes a transverse bolt, a vertical bolt and a bolt movement mechanism located in the shell; the bolt movement mechanism includes a vertical transmission member, a transverse transmission member, a base, and a torque mechanism, the bolt limiting mechanism consists of an electromagnetic barrier rod and a limiting bayonet arranged at a position corresponding to the extended end of the electromagnetic barrier rod when the torque mechanism is locked, the electromagnetic barrier rod consists of an electromagnetic coil, a movable iron core and a barrier rod coaxially connected to the iron core, the iron core is extended or retracted by utilizing magnetic force generation or cancellation, thereby driving the barrier rod to extend or retract, and when the electromagnetic barrier rod is extended, it cooperates with the limiting bayonet on the torque mechanism to prevent the torsion mechanism from rotating, and when the electromagnetic barrier rod is retracted, the limiting effect is cancelled and the bolt movement mechanism is in a movable state. Its working process is: when unlocking, after the electromagnetic lever receives the unlocking signal from the electronic control module, the electromagnetic lever is energized and retracted, canceling the limiting effect on the torque mechanism, and manually rotating the knob on the panel drives the torque mechanism to rotate, and the torque mechanism then drives the transverse transmission member to move laterally into the shell, and the transverse lock bolt retracts into the shell. At the same time, the sliding connection between the transverse transmission member and the vertical transmission member causes the vertical transmission member to also move into the shell, and the vertical lock bolt retracts into the shell, thereby realizing three-way lock control unlocking.

[0004] However, the above-mentioned electric semi-automatic lock has the following disadvantages: since the movement of the electromagnetic lever is controlled by the electronic control module to achieve unlocking or locking, when the electronic control module fails, it may be impossible to unlock the lock, thereby affecting the use in an emergency. Summary of the invention

[0005] The purpose of the present invention is to provide a safe lock body with an emergency key, which adopts an electromagnetic control mechanism and a mechanical control mechanism to simultaneously control unlocking, has a two-way unlocking effect, and is more convenient to use in an emergency.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a safe lock body with an emergency key comprises a housing, a cover arranged on the housing, and an electronic control module, a handle body is rotatably arranged on the cover, a linkage plate is movably arranged in the housing, a lock column and a lock block are arranged on the linkage plate, the lock column is fixedly connected to the linkage plate, and the lock block is movably arranged on the linkage plate through a transmission component.

[0007] An electromagnetic control mechanism and a mechanical control mechanism are arranged in the shell, the electronic control module is electrically connected to the electromagnetic control mechanism, a torque assembly is arranged on the handle body, the torque assembly comprises a rotating sleeve fixedly connected to the handle body, a knob rotatably sleeved on the rotating sleeve, a linkage structure is arranged between the knob and the linkage plate, and when the knob is rotated, the linkage plate is driven to move relative to the shell;

[0008] A first clutch mechanism is provided between the electromagnetic control mechanism and the torque assembly, and a second clutch mechanism is provided between the mechanical control mechanism and the torque assembly. The electromagnetic control mechanism drives the knob and the rotating sleeve to rotate integrally through the first clutch mechanism, and the mechanical control mechanism drives the knob and the rotating sleeve to rotate integrally through the second clutch mechanism.

[0009] By adopting the above technical scheme, under normal conditions, the lock cylinder and the lock block extend out of the housing; when electronic unlocking is adopted, after the electronic control module passes the verification, the electromagnetic control mechanism is energized, and the electromagnetic control mechanism acts on the first clutch mechanism to make the knob and the rotating sleeve relatively fixed. At this time, the knob can be driven to rotate by turning the handle body, and the knob drives the linkage plate to move relative to the housing through the linkage structure, so that the lock block and the lock cylinder are retracted into the housing at the same time to achieve unlocking; when manual unlocking is adopted, the key is inserted into the mechanical control mechanism, and the mechanical control mechanism acts on the second clutch mechanism to make the knob and the rotating sleeve relatively fixed. At this time, the knob can be driven to rotate by turning the handle body, and the knob drives the linkage plate to move to achieve unlocking. The electromagnetic control mechanism or the mechanical control mechanism is used to control separately, so that the knob and the rotating sleeve are clutched. When the knob and the rotating sleeve are relatively integrated, the handle body can be turned to achieve unlocking, which has the effect of two-way unlocking. When the electromagnetic control mechanism cannot achieve unlocking, the mechanical control mechanism can be used to unlock, which is more convenient to use, suitable for emergency, and the structural design is more reasonable and ingenious.

[0010] The present invention is further configured as follows: the electromagnetic control mechanism includes an electromagnet assembly, the knob is provided with a mounting hole, the rotating sleeve is provided with a first notch corresponding to the mounting hole, the first clutch mechanism includes an electromagnetic baffle rod movably arranged in the mounting hole, when the electromagnetic control mechanism generates magnetic force on the electromagnetic baffle rod, the electromagnetic baffle rod extends into the mounting hole and the first notch, and a reset assembly is provided on the electromagnetic baffle rod, and the reset assembly ensures that the electromagnetic baffle rod always has a tendency to move away from the first notch.

[0011] By adopting the above technical solution, when the electromagnetic control mechanism is used to unlock, the electromagnet assembly is energized to generate a repulsive force on the electromagnetic barrier rod, and the electromagnetic barrier rod moves toward the first notch in the mounting hole. When the electromagnetic barrier rod passes through the first notch and the mounting hole at the same time, the knob and the rotating sleeve are relatively stopped. In this way, when the handle body is rotated, the rotating sleeve and the knob can be driven to rotate at the same time; when the knob is reset, the electromagnetic control mechanism no longer generates magnetic force, and the inner end of the electromagnetic barrier rod is driven by the reset assembly to disengage from the first notch, so that the knob and the rotating sleeve are separated and can rotate relative to each other again.

[0012] The present invention is further configured as follows: the mechanical control mechanism includes a lock core, the handle body is provided with a sliding hole, the second clutch mechanism includes a clutch plate slidably arranged in the sliding hole, the rotating sleeve is provided with a through hole for the clutch plate to slide radially, the knob is provided with a second notch corresponding to the through hole, the lock core is provided with a driving mechanism, and when the lock core rotates, the clutch plate is driven through the second notch by the driving mechanism.

[0013] By adopting the above technical solution, when the mechanical control mechanism is used to unlock the lock, the key is inserted into the lock core, and after the lock core is rotated, the clutch plate is moved relative to the through hole through the driving mechanism until one end of the clutch plate passes through the second notch. At this time, the clutch plate is simultaneously located in the through hole and the second notch, and the knob and the rotating sleeve are relatively stopped. In this way, when the handle body is rotated, the rotating sleeve and the knob can be driven to rotate at the same time.

[0014] The present invention is further configured as follows: the driving mechanism includes an eccentric column and a sliding groove, the eccentric column is arranged at the end of the lock core, and the sliding groove is opened in the clutch plate. When the lock core drives the eccentric column to rotate, the eccentric column moves relative to the sliding groove, causing the clutch plate to slide relative to the through hole.

[0015] The present invention is further configured as follows: a lug is provided on the side wall of the knob, and the linkage structure comprises a guide column provided on the lug and a strip hole opened on the linkage plate.

[0016] By adopting the above technical solution, when the knob is rotated, the guide column on the lug is driven to rotate, and the guide column rotates around the knob shaft, and the guide column slides in the strip hole, thereby driving the linkage plate to slide.

[0017] The present invention is further configured as follows: the transmission assembly includes a boss arranged on the linkage plate and an inclined groove opened on the locking block, and the side wall of the shell is provided with a side wall through-hole for the locking block to pass through. When the linkage plate slides, the locking block slides under the guiding action of the transmission assembly, and the sliding direction of the locking block is perpendicular to the sliding direction of the linkage plate.

[0018] By adopting the above technical solution, when the linkage plate moves, the boss is driven to move. Since the locking block is limited by the side wall perforation, it can only move axially along the side wall perforation. When the boss slides relative to the inclined groove, it drives the locking block to extend or retract relative to the side wall perforation.

[0019] The present invention is further configured as follows: a retaining ring is fixedly provided on the side wall of the electromagnetic retaining rod, a limit retaining ring cooperating with the retaining ring is provided in the mounting hole, and the reset assembly includes a reset spring sleeved on the electromagnetic retaining rod, and the reset spring enables the electromagnetic retaining rod to always have a movement tendency to extend out of the mounting hole.

[0020] By adopting the above technical solution, when the electromagnetic stop rod is no longer affected by the magnetic force of the electromagnetic control mechanism, the electromagnetic stop rod disengages from the first notch under the elastic force of the reset spring to achieve reset, and the limit stop ring and the stop ring resist each other to prevent the electromagnetic stop rod from disengaging from the mounting hole.

[0021] The present invention is further configured as follows: a mounting plate is arranged inside the housing, a first return torsion spring is arranged between the mounting plate and the knob; and a second return torsion spring is arranged between the handle body and the housing.

[0022] By adopting the above technical solution, when unlocking is completed, the handle body is released, and the handle body is reset under the elastic force of the second reset torsion spring, and the knob is reset under the elastic force of the first reset torsion spring. Both places are reset at the same time, and the reliability is high.

[0023] The present invention is further configured as follows: the lock core is coaxially arranged with the rotating shaft of the handle body, and the lock core is arranged in the handle body, a through hole communicating with the lock core is opened on the handle body, and a cover plate is detachably connected to the through hole.

[0024] By adopting the above technical solution, the cover plate is covered on the through hole without using a mechanical control mechanism. On the one hand, the cover plate can protect the lock core, and on the other hand, the aesthetics is also high. When the mechanical control mechanism is used to unlock the lock, the cover plate can be removed and the key can be inserted into the lock core.

[0025] The present invention is further configured as follows: a micro switch and an alarm device are arranged in the housing, the micro switch is electrically connected to the alarm device, and the micro switch is in contact with the linkage plate.

[0026] By adopting the above technical solution, the linkage plate retracts into the shell during the unlocking process. When the end of the linkage plate close to the micro switch contacts the micro switch, the alarm device is driven to emit an alarm sound or prompt tone to indicate that the lock has been unlocked.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. The electromagnetic control mechanism or mechanical control mechanism is used to control the knob and the rotating sleeve separately, so that the knob and the rotating sleeve are connected and engaged. When the knob and the rotating sleeve are relatively integrated, the handle body can be turned to unlock, which has the effect of two-way unlocking. When the electromagnetic control mechanism cannot unlock, the mechanical control mechanism can be used to unlock in an emergency. It is more convenient to use and the structural design is more reasonable and ingenious.

[0029] 2. The first reset torsion spring and the second reset torsion spring are used to control the reset of the knob and the handle body respectively, which has high reliability;

[0030] 3. The lock core is arranged in the handle body, which occupies less space and has a more reasonable structural design. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] A safe lock body with an emergency key, such as Figure 1-3 , Figure 5 As shown, it includes a housing 1 and a cover 2 arranged on the housing 1, a battery box 11 and an electronic control module 12 are also arranged on the housing 1, a mask 21 is arranged on the cover 2, a password unlocking panel 22 and a handle body 3 are arranged on the mask 21, a fixing plate 23 is fixedly connected to the outer wall of the cover 2 by bolts, a triangular mounting frame 24 is fixedly arranged on the fixing plate 23, the handle body 3 is rotatably connected to the cover 2 through the triangular mounting frame 24, and the connecting end of the handle body 3 extends into the housing 1. A connecting hole 31 is arranged on the side wall of the handle body 3, a second reset torsion spring 32 is arranged between the handle body 3 and the mask 21, one end of the second reset torsion spring 32 penetrates the connecting hole 31, and the other end of the second reset torsion spring 32 is fixed to the mask 21, and the second reset torsion spring 32 drives the handle body 3 to reset.

[0044] like Figure 4 and Figure 5As shown, a linkage plate 4 is movably arranged in the housing 1, and two horizontal locking columns 41 are fixedly connected to the left end of the linkage plate 4. Two opposite locking blocks 42 are also slidably arranged on the linkage plate 4 through a transmission assembly. The transmission assembly includes a boss 44 arranged on the linkage plate 4 and an inclined groove 421 opened in the locking block 42. The upper and lower side walls of the housing 1 are provided with side wall through holes 13 for the upper and lower locking blocks 42 to pass through. The left end of the housing 1 is provided with an end through hole 14 for the locking column 41 to pass through. When the linkage plate 4 moves to the right, the boss 44 is driven to move. Since the locking block 42 is limited by the side wall through hole 13, it can only move along the axial direction of the side wall through hole 13 (i.e. Figure 5 When the boss 44 slides relative to the inclined groove 421, the locking block 42 is driven to extend or retract relative to the side wall through hole 13.

[0045] like Figure 2 , Figure 6-9 As shown, an electromagnetic control mechanism is provided in the housing 1, and the electronic control module 12 is electrically connected to the electromagnetic control mechanism. The end of the handle body 3 extending into the housing 1 is fixedly connected with a hollow hexagonal column 33, on which a torque assembly is sleeved, and a strip-shaped avoidance hole 45 is provided on the linkage plate 4 to slide with the torque assembly. The torque assembly includes a rotating sleeve 6 sleeved on the hexagonal column 33, a knob 7 rotatably sleeved on the rotating sleeve 6, and the inner wall of the rotating sleeve 6 is provided with a hexagonal hole 61 adapted to the hexagonal column 33, and the rotating sleeve 6 is locked with the hexagonal column 33. The electromagnetic control mechanism includes an electromagnet assembly 5, a mounting hole 71 is provided on the side wall of the knob 7, a first notch 62 corresponding to the mounting hole 71 is provided on the rotating sleeve 6, and a first clutch mechanism is provided between the electromagnetic control mechanism and the torque assembly. The first clutch mechanism includes an electromagnetic blocking rod 8 movably arranged in the mounting hole 71, a blocking ring 81 is fixedly provided on the side wall of the electromagnetic blocking rod 8, and a reset spring 82 is also sleeved on the electromagnetic blocking rod 8, one end of the reset spring 82 abuts against the blocking ring 81, and the other end of the reset spring 82 abuts against the step on the inner wall of the mounting hole 71, and a limit retaining ring 711 that is limitedly matched with the blocking ring 81 is provided in the mounting hole 71, and the reset spring 82 makes the electromagnetic blocking rod 8 always have a movement tendency to extend out of the mounting hole 71. The electromagnetic control mechanism drives the knob 7 and the rotating sleeve 6 to rotate integrally through the first clutch mechanism.

[0046] like Figure 1 , Figure 7 , Fig. 9 and Fig.10As shown, a mechanical control mechanism is also provided in the housing 1, and a second clutch mechanism is provided between the mechanical control mechanism and the torque assembly. The mechanical control mechanism includes a lock core 9, which is coaxially arranged with the rotating shaft of the handle body 3, and the lock core 9 is arranged in the handle body 3. An eccentric column 91 is provided at the inner end of the lock core 9, and the lock core 9 extends into the hexagonal column 33, and a sliding hole 331 is radially opened on the side wall of the hexagonal column 33. The second clutch mechanism includes a clutch plate 92 slidably arranged in the sliding hole 331, and the clutch plate 92 is a rectangular parallelepiped as a whole, and a hole is opened on the clutch plate 92 for the eccentric column 91 to extend. The sliding groove 93 is inserted into the rotating sleeve 6, the side wall of the rotating sleeve 6 is provided with a through hole 63 for the clutch plate 92 to slide, and the side wall of the knob 7 is provided with a second notch 72 corresponding to the through hole 63. When the lock cylinder 9 rotates, the eccentric column 91 is driven to rotate, and the eccentric column 91 moves relative to the sliding groove 93. The clutch plate 92 is restricted by both sides of the sliding hole 331 and cannot rotate, so that the clutch plate 92 slides relative to the through hole 63, thereby driving the clutch plate 92 to pass through the through hole 63 and the second notch 72 in sequence. In this way, the mechanical control mechanism can drive the knob 7 and the rotating sleeve 6 to rotate integrally through the second clutch mechanism. A limiting column 94 is provided on the side wall of the lock cylinder 9, and an arc-shaped limiting groove 332 is correspondingly provided on the side wall of the hexagonal column 33. When the lock cylinder 9 rotates relative to the handle body 3, the limiting column 94 moves along the arc-shaped limiting groove 332 to limit the rotation angle of the lock cylinder 9. A through hole 34 communicating with the lock core 9 is formed on the handle body 3 , and a cover plate 10 is detachably connected to the through hole 34 .

[0047] like Figure 5-7 As shown, the side wall of the knob 7 is provided with a lug 73, and the lug 73 is provided with a guide column 731 extending toward the linkage plate 4, and the linkage plate 4 is provided with a strip hole 43, and the guide column 731 is slidably connected to the strip hole 43. When the knob 7 drives the lug 73 to rotate, the lug 44 slides along the strip hole 43, thereby driving the linkage plate 4 to move relative to the housing 1. A mounting plate 15 is provided in the housing 1, and a first reset torsion spring 74 is provided between the mounting plate 15 and the knob 7, and a fixing column 151 is provided on the mounting plate 15. The knob 7 is provided with a plug-in hole 75, and one end of the first reset torsion spring 74 is plugged into the plug-in hole 75, and the other end of the first reset torsion spring 74 is fixed to the fixing column 151.

[0048] like Figure 5 As shown, a micro switch 16 and an alarm device are provided in the housing 1, the micro switch 16 is electrically connected to the alarm device, and the micro switch 16 abuts against the right end of the linkage plate 4. During the unlocking process, the linkage plate 4 retracts into the housing 1, and when the end of the linkage plate 4 close to the micro switch 16 abuts against the micro switch 16, the alarm device is driven to emit an alarm sound or a prompt sound, indicating that the door has been unlocked.

[0049] The basic working principle of the present invention is as follows: under normal conditions, the lock column 41 and the lock block 42 extend out of the housing 1, that is, they are in a locked state; when electronic unlocking is adopted, a password is inputted into the password unlocking panel 22, and after the electronic control module 12 passes the verification, the electromagnet assembly 5 is energized to generate a repulsive force on the electromagnetic blocking rod 8, and the electromagnetic blocking rod 8 moves toward the first notch 62 in the mounting hole 71. When the electromagnetic blocking rod 8 passes through the first notch 62 and the mounting hole 71 at the same time, the knob 7 and the rotating sleeve 6 are relatively stopped. At this time, the knob 7 can be driven to rotate in a Figure 6 The knob 7 rotates counterclockwise, and the guide column 731 on the lug 73 rotates when the knob 7 rotates. The guide column 731 rotates around the knob 7 shaft, and the guide column 731 slides in the strip hole 43, so that the linkage plate 4 can slide, and the linkage plate 4 drives the lock column 41 and the lock block 42 to retract, thereby unlocking. When the unlocking is completed, the handle body 3 is released, and the handle body 3 is reset under the elastic force of the second reset torsion spring 32, and the knob 7 is reset under the elastic force of the first reset torsion spring 74. When re-locking, when the electromagnetic blocking rod 8 is no longer affected by the magnetic force of the electromagnetic control mechanism, the electromagnetic blocking rod 8 is separated from the first notch 62 under the elastic force of the reset spring 82 to reset, and the knob 7 is separated from the rotating sleeve 6, and can be relatively rotated again. The limit ring 711 and the retaining ring 81 resist each other, which can prevent the electromagnetic blocking rod 8 from being separated from the mounting hole 71. It should be noted that when the electromagnet assembly 5 is energized, the repulsive force generated by the electromagnet assembly 5 on the electromagnetic lever is always greater than the elastic force of the return spring 82 .

[0050] When manual unlocking is adopted, the key is inserted into the lock core 9. After the lock core 9 is rotated, the eccentric column 91 drives the clutch plate 92 to move until the clutch plate 92 is located in the through hole 63 and the second notch 72 at the same time, and the knob 7 and the rotating sleeve 6 are relatively stopped. In this way, when the handle body 3 is rotated, the rotating sleeve 6 and the knob 7 can be driven to rotate at the same time to realize the mechanical unlocking process. The movement process of the linkage plate 4 driven by the knob 7 is the same as that of the electronic unlocking and will not be repeated here.

[0051] Under normal use (i.e., without the need to use the emergency key to unlock), the cover plate 10 can be covered on the through hole 34. The hidden design can, on the one hand, protect the lock cylinder 9, and on the other hand, it is also more aesthetically pleasing. When the emergency key is used to unlock in an emergency, the cover plate 10 can be removed to expose the keyhole of the lock cylinder 9, and the key can be inserted into the lock cylinder 9. Non-professional users cannot know that the cover plate 10 can be opened to unlock the door with the key, thereby increasing safety.

[0052] An electromagnetic control mechanism or a mechanical control mechanism is used for control respectively, and a clutch mechanism is set between the knob 7 and the rotating sleeve 6. When the knob 7 and the rotating sleeve 6 are relatively integrated, the handle body 3 can be rotated to achieve unlocking, which has a two-way unlocking effect. When the electromagnetic control mechanism cannot achieve unlocking, the mechanical control mechanism can be used to unlock in an emergency. It is more convenient to use and the structural design is reasonable and ingenious.

[0053] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
