Description

Technical Field

[0001] The invention relates to the technical field of unlocking equipment, in particular to a single-handle explosion-proof key unlocking mechanism and a single-handle explosion-proof key. Background Art

[0002] In the power error prevention system, locks are usually used for management and control to protect various types of power equipment from arbitrary use and damage. In order to increase the unlocking and locking authority of the locks, smart keys are usually used to authorize the locks to unlock. Therefore, the unlocking module in the key plays a key role in the authorization process.

[0003] Existing unlocking modules use electromagnetic components to provide driving force for authorization elements. Solenoids are often used as driving elements for smart keys because of their simple structure. However, solenoids require large inductance and current to provide electromagnetic force when working. For some places with explosion risks, their large current and inductance values ​​cannot meet the minimum requirements of explosion-proof standards. If the inductance and current values ​​of the solenoid are reduced, the driving force will be insufficient and the action cannot be completed. In addition, the characteristics of the solenoid itself also have the disadvantage of being unlocked by impact or knocking. Therefore, for occasions with high explosion-proof requirements, a more stable and reliable unlocking module is needed. Summary of the invention

[0004] The main purpose of the present invention is to provide a single-handle explosion-proof key unlocking mechanism and a single-handle explosion-proof key to solve the problem that the unlocking module in the prior art is not suitable for occasions with explosion-proof requirements.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a single-handle explosion-proof key unlocking mechanism is provided, comprising: a shell, an opening is provided on the shell; an unlocking rod, which can be installed at the opening from the inner side of the shell, and a part of the unlocking rod can extend from the opening; an unlocking head for docking with the transmission member of the lock core, the unlocking head is connected to an end of the unlocking rod extending out of the shell; a locking shaft for cooperating with the insertion hole of the lock core, the locking shaft sleeve is arranged on the outer side of the unlocking rod; a locking assembly, the locking assembly is movably arranged in the shell, and has a locking position that hinders the relative rotation between the unlocking rod and the locking shaft, and an unlocking position that avoids the relative rotation between the unlocking rod and the locking shaft; a motor assembly, the motor assembly is threadedly driven connected to the locking assembly, and can drive the locking assembly to move axially to drive the locking assembly to telescopically move between the locked position and the unlocked position.

[0006] Furthermore, the motor assembly includes a drive motor and a screw, the screw is drivingly connected to the output shaft of the drive motor, the screw and the locking assembly both have a threaded structure and are threadedly matched, and the drive motor drives the locking assembly to move via the screw so that the locking assembly moves between a locked position and an unlocked position.

[0007] Furthermore, one end of the screw rod facing the locking assembly has a protrusion, and when the locking assembly and the screw rod are threadedly engaged to an extreme position, the protrusion abuts against the locking assembly to limit the relative position between the locking assembly and the screw rod.

[0008] Furthermore, the locking assembly includes a locking part and a transmission part, a first limiting structure is provided between the locking part and the transmission part, the first limiting structure limits the relative rotation between the locking part and the transmission part, and a second limiting structure is provided between at least one of the locking part and the transmission part and the unlocking rod, the second limiting structure limits the relative rotation of the locking part and the transmission part relative to the unlocking rod.

[0009] Further, the first limiting structure includes a first protrusion and a first groove, one of the locking part and the transmission part has a first protrusion, and the other of the locking part and the transmission part has a first groove, the first groove extends along the axial direction of the motor assembly, and the first protrusion is located in the first groove. When the transmission part moves away from the unlocking rod under the drive of the motor assembly, the first protrusion abuts against the side walls of the first groove, and the transmission part drives the locking part to withdraw from the unlocking rod and the locking shaft through the first protrusion and the first groove to avoid relative rotation between the unlocking rod and the locking shaft.

[0010] Furthermore, the second limiting structure includes a second protrusion and a second groove, one of the unlocking rod and the locking part has a second protrusion, and the other of the unlocking rod and the locking part has a second groove, the second groove extends along the axial direction of the motor assembly, and the second protrusion is located in the second groove. When the locking part moves axially, the second protrusion moves in the second groove.

[0011] Furthermore, the locking assembly also includes an elastic member, both ends of which are respectively in contact with the locking part and the transmission part, and provide elastic force for the locking part and the transmission part to move away from each other. The unlocking rod and the locking shaft respectively have a locking hole and a locking notch for the locking assembly to extend into. The unlocking rod and the locking shaft have an alignment state in which the locking hole and the locking notch are circumferentially aligned, and a circumferential staggered state in which the locking hole and the locking notch are circumferentially aligned. When the unlocking rod and the locking shaft are in the staggered state, the locking part abuts against the end of the locking shaft under the action of the elastic member and remains in the unlocked position.

[0012] Furthermore, the spacing distance between the locking part and the transmission part is smaller than the initial length of the elastic member, the elastic member is always in a compressed state, and provides elastic force for the locking part and the transmission part to move away from each other. When the single-handle explosion-proof key unlocking mechanism unlocks the lock cylinder, the motor assembly acts in the reverse direction, the transmission part compresses the elastic member, and the locking part abuts against the locking shaft; when the single-handle explosion-proof key unlocking mechanism resets itself, the locking part moves to the locked position under the action of the elastic member.

[0013] Furthermore, the unlocking head is sleeved on the outside of the unlocking rod, and along the axial direction of the unlocking rod, the locking shaft is located between the unlocking head and the housing to control the axial movement of the locking shaft.

[0014] Furthermore, the unlocking rod includes a first section, a second section and a third section connected in sequence along the axial direction, the first section is used to install the unlocking head, the second section is used to install the locking shaft, the locking hole is located on the circumferential side of the second section, and the third section is used to install the motor assembly, and the diameters of the first section, the second section and the third section increase successively.

[0015] Furthermore, the single-handle explosion-proof key unlocking mechanism also includes a detection component, and at least one of the unlocking rod, the locking component and the motor component cooperates with the detection component. The detection component determines the state of the single-handle explosion-proof key unlocking mechanism by detecting at least one of the unlocking rod, the locking component and the motor component.

[0016] Furthermore, the detection component includes a photoelectric detection element located on one side of the locking component. The locking component has a detection end. When the locking component is in the locked position or the unlocked position, the detection end triggers the photoelectric detection element. The photoelectric detection element detects the detection end to determine the state of the single-handle explosion-proof key unlocking mechanism.

[0017] Furthermore, the detection component includes a magnetic part and a sensing part. The magnetic part is connected to the locking shaft and moves synchronously. The sensing part is arranged in the shell. When the unlocking rod rotates, the sensing part senses the position change of the magnetic part to determine the state of the single-handle explosion-proof key unlocking mechanism.

[0018] Furthermore, the single-handle explosion-proof key unlocking mechanism also includes: a conductive electrode for electrically connecting to an electrical lock, the conductive electrode being located on the side of the shell; a power supply and code reading coil for supplying power to the lock core and reading and identifying codes, the power supply and code reading coil being arranged in the shell; a transmission communication module for communicating and interacting with the control end, the transmission communication module being arranged in the shell; a control board, the control board being electrically connected to the conductive electrode, the power supply and code reading coil, the transmission communication module and the motor assembly to control the action of the single-handle explosion-proof key unlocking mechanism.

[0019] According to another aspect of the present invention, a single-handle explosion-proof key is provided, comprising the above-mentioned single-handle explosion-proof key unlocking mechanism.

[0020] The technical solution of the present invention is applied, and a motor assembly is adopted, and the motor assembly and the locking assembly are driven by a threaded drive to realize driving the locking assembly. Specifically, when not unlocked, the locking assembly is in the locked position. At this time, the locking assembly extends into the unlocking rod and the locking shaft at the same time, so that the locking assembly is stopped between the locking shaft and the unlocking rod, so that the locking shaft and the unlocking rod cannot rotate relative to each other, and even if the unlocking rod is inserted into the insertion hole of the lock core, it cannot rotate to achieve unlocking; and when unlocking, the motor assembly is actuated, and the motor assembly drives the locking assembly to move through the thread, so that the locking assembly moves axially, thereby switching to the unlocking position, and the locking assembly withdraws from the unlocking rod and the locking shaft, and the locking assembly is no longer stopped between the locking shaft and the unlocking rod, so that the locking shaft and the unlocking rod can rotate relative to each other. At this time, due to the cooperation between the locking shaft and the insertion hole of the lock core, the locking shaft is restricted and cannot rotate, while the unlocking rod can rotate, so that the unlocking head drives the transmission member of the lock core to rotate, thereby achieving unlocking of the lock core; after unlocking, the locking assembly can be maintained in the unlocking position. The above-mentioned setting adopts the motor drive mode, which meets the explosion-proof standards of the scene while ensuring stable and reliable normal unlocking and locking control, and can be used in occasions with explosion-proof standards. At the same time, compared with the traditional solenoid drive, the motor drive is more stable and reliable, avoiding the problem of unlocking failure when being knocked and dropped. In addition, this embodiment also designs the specific structure of the locking component, so that the motor component and the locking component can achieve both drive unlocking and unlocking retention, and can also achieve the effect of automatic reset.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0038] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0039] In order to solve the problem that the unlocking module in the prior art is not suitable for occasions with explosion-proof requirements, the present invention provides a single-handle explosion-proof key unlocking mechanism and a single-handle explosion-proof key. The single-handle explosion-proof key has the following single-handle explosion-proof key unlocking mechanism.

[0040] like Figures 1 to 12 The single-handle explosion-proof key unlocking mechanism shown in the figure includes a shell 10, an unlocking rod 20, an unlocking head 24 for docking with the transmission member of the lock core, a locking shaft 30 for cooperating with the jack of the lock core, a locking assembly 40 and a motor assembly 50. The shell 10 is provided with an opening; the unlocking rod 20 can be installed at the opening from the inner side of the shell 10, and a part of the unlocking rod 20 can extend from the opening; the unlocking head 24 is connected to the end of the unlocking rod 20 extending out of the shell 10; the locking shaft 30 is sleeved on the outside of the unlocking rod 20; the locking assembly 40 is movably arranged in the shell 10, and has a locking position that hinders the relative rotation between the unlocking rod 20 and the locking shaft 30, and an unlocking position that avoids the relative rotation between the unlocking rod 20 and the locking shaft 30; the motor assembly 50 is threadedly driven connected to the locking assembly 40, and can drive the locking assembly 40 to move axially to drive the locking assembly 40 to telescopically move between the locked position and the unlocked position.

[0041] The present embodiment uses a motor assembly 50, and the motor assembly 50 and the locking assembly 40 are driven by a threaded drive to drive the locking assembly 40. Specifically, when not unlocked, the locking assembly 40 is in the locked position. At this time, the locking assembly 40 simultaneously extends into the unlocking rod 20 and the locking shaft 30, so that the locking assembly 40 is stopped between the locking shaft 30 and the unlocking rod 20, so that the locking shaft 30 and the unlocking rod 20 cannot rotate relative to each other, and even if the unlocking rod 20 is inserted into the jack of the lock core, it cannot rotate to unlock; when unlocking, the motor assembly 50 is actuated, and the motor assembly 50 is driven. 50 drives the locking assembly 40 to move by threading, so that the locking assembly 40 moves axially, thereby switching to the unlocking position, and the locking assembly 40 withdraws from the unlocking rod 20 and the locking shaft 30, and the locking assembly 40 is no longer blocked between the locking shaft 30 and the unlocking rod 20, so that the locking shaft 30 and the unlocking rod 20 can rotate relative to each other. At this time, since the locking shaft 30 cooperates with the jack of the lock core, the locking shaft 30 is restricted from rotating, while the unlocking rod 20 can rotate, so that the unlocking head 24 drives the transmission part of the lock core to rotate, and the lock core is unlocked; after unlocking, the locking assembly 40 can remain in the unlocking position. The above-mentioned setting method adopts the motor drive method. Under the premise of ensuring stable and reliable normal unlocking control, it meets the explosion-proof standard of the scene and can be used in occasions with explosion-proof standard requirements. At the same time, compared with the traditional solenoid drive, the motor drive is more stable and reliable, avoiding the problem of unlocking failure when being knocked and dropped. In addition, the present embodiment designs the specific structure of the locking assembly 40 so that the motor assembly 50 and the locking assembly 40 can achieve both drive unlocking and unlocking retention, as well as automatic resetting.

[0042] The locking assembly 40 of this embodiment includes a locking part 41 and a transmission part 42, wherein the transmission part 42 cooperates with the motor assembly 50, and the locking part 41 cooperates with the unlocking rod 20 and the locking shaft 30. Of course, the locking assembly 40 is not limited to the method of this embodiment, and an integral structure or the like may also be adopted. Since this embodiment adopts the locking assembly 40 to simultaneously extend into or withdraw from the unlocking rod 20 and the locking shaft 30 to achieve the effect of stopping rotation and avoiding, the locking hole 21 and the locking notch 31 for the locking assembly 40 to extend into are respectively provided on the unlocking rod 20 and the locking shaft 30 of this embodiment, and the locking part 41 of the locking assembly 40 can extend into the locking hole 21 and the locking notch 31, thereby achieving the effect of hindering the relative rotation between the unlocking rod 20 and the locking shaft 30. Of course, in addition to the method of opening holes and notches, the method of two convex columns abutting against each other may also be adopted to achieve the effect of stopping rotation.

[0043] In this embodiment, the motor assembly 50 and the locking assembly 40 are driven and connected by threaded matching. Specifically, the motor assembly 50 includes a driving motor 51 and a screw 52. The driving motor 51 can be fixedly arranged on the housing 10 or the unlocking rod 20 by means of a motor bracket and other components, and the screw 52 is drivingly connected to the output shaft of the driving motor 51. The screw 52 and the transmission part 42 both have a threaded structure and the two are threadedly matched with each other. In this way, when unlocking, the driving motor 51 drives the screw 52 to rotate, and the rotation of the screw 52 drives the transmission part 42 to move axially through the threaded matching, so that the locking part 41 moves between the locked position and the unlocked position. Of course, the specific structural form of the threaded matching is not limited to the above-mentioned method in this embodiment, and other threaded structures, such as gear racks, can also be used to achieve drive matching.

[0044] like Figure 3 As shown, in the present embodiment, the end of the screw rod 52 facing the transmission part 42 has a spherical protrusion 521, and the middle of the transmission part 42 is not completely hollow, but forms a blind hole structure, and the inner wall of the blind hole has a thread, so as to cooperate with the thread of the screw rod 52. Due to the blind hole structure, when the transmission part 42 and the screw rod 52 are threaded to the extreme position, the locking assembly 40 is in the unlocking position. At this time, the protrusion 521 abuts against the bottom wall of the blind hole, so that the screw rod 52 and the transmission part 42 cannot continue to rotate relative to each other, thereby limiting the relative position between the transmission part 42 and the screw rod 52, avoiding the situation where the threads of the transmission part 42 and the screw rod 52 are too engaged and stuck, and ensuring the overall smooth movement.

[0045] In this embodiment, a first limiting structure is provided between the locking part 41 and the transmission part 42, and the first limiting structure limits the relative rotation between the locking part 41 and the transmission part 42. At the same time, a second limiting structure is provided between at least one of the locking part 41 and the transmission part 42 and the unlocking rod 20, and the second limiting structure limits the relative rotation of the locking part 41 and the transmission part 42 relative to the unlocking rod 20. In this way, the first limiting structure can prevent the locking part 41 and the transmission part 42 from relative rotation and can only move axially, while the second limiting structure can prevent at least one of the locking part 41 and the transmission part 42 from relative rotation with the unlocking rod 20, thereby making the locking part 41, the transmission part 42, and the unlocking rod 20 only able to move axially relative to each other and unable to rotate circumferentially, thereby ensuring the reliability of the movement of the locking part 41 and the transmission part 42.

[0046] In this embodiment, the locking assembly 40 includes a locking portion 41, a transmission portion 42 and an elastic member 43. Figure 4As shown, the locking portion 41 adopts a locking pin, which has a locking end 411. The locking end 411 can extend into or out of the locking hole 21 and the locking notch 31. The locking end 411 of this embodiment adopts a long columnar shape and is located at one end of the locking portion 41 close to the unlocking rod 20. Since the locking end 411 cooperates with the locking hole 21 and the locking notch 31, the specific size of the locking end 411 can be matched with the size of the hole formed by the locking hole 21 and the locking notch 31, ensuring that a part of the locking end 411 is located in the locking hole 21 and the other part is located in the locking notch 31. Therefore, the locking end 411 can extend into and out of the locking hole 21 and the locking notch 31 to achieve the effect of locking or unlocking the relative rotation between the unlocking rod 20 and the locking shaft 30. Figure 5 As shown, the transmission part 42 as a whole adopts a sleeve-shaped structure, more specifically a nut structure. A blind hole is opened on the end face of one end of the transmission part 42, and the blind hole has an internal thread, so as to cooperate with the screw rod 52 to achieve the effect of threaded drive cooperation with the motor assembly 50. When the motor assembly 50 is actuated, the transmission part 42 can be driven axially by the screw rod 52. The elastic member 43 is arranged between the locking part 41 and the transmission part 42, and the two ends of the elastic member 43 are respectively in contact with the locking part 41 and the transmission part 42. The elastic member 43 of this embodiment adopts a spring, and the spacing distance between the locking part 41 and the transmission part 42 is less than the initial length of the elastic member 43, so that the elastic member 43 is always in a compressed state, and then the spring always provides the locking part 41 and the transmission part 42 with elastic force to move away from each other, so that the spring always gives the locking part 41 elastic force to extend into the locking hole 21 and the locking notch 31, so that the locking part 41 always has a movement tendency to extend into the locking hole 21 and the locking notch 31, so that automatic resetting can be achieved by the spring when resetting. In order to ensure that the spring is always in a compressed state, the transmission part 42 is supported by the screw 52 during installation so that the spring is slightly compressed by the locking part 41 and the transmission part 42, and the spring's own elastic force makes the screw 52 and the transmission part 42 tangent to each other's threads, so as to ensure that the screw teeth between the two are in a critical meshing state. At the same time, guide columns are arranged in the locking part 41 and the transmission part 42 , and the spring is sleeved on the guide columns, so as to ensure that the elastic force of the spring acts on the locking part 41 and the transmission part 42 .

[0047] In this embodiment, in addition to the elastic member 43, a first limiting structure is also provided between the locking portion 41 and the transmission portion 42, and when unlocking, the transmission portion 42 drives the locking portion 41 to move to the unlocking position through the first limiting structure. Figure 4 and Figure 5As shown, the first limiting structure includes a first protrusion 421 and a first groove 412. One of the locking part 41 and the transmission part 42 has the first protrusion 421, and the other of the locking part 41 and the transmission part 42 has the first groove 412. The first protrusion 421 is located in the first groove 412, and the first groove 412 extends along the axial direction of the motor assembly 50. In this way, when unlocking, the driving motor 51 is activated to drive the screw rod 52 to rotate, and the screw rod 52 drives the transmission part 42 to move axially in a direction away from the unlocking rod 20. At this time, the first protrusion 421 and one end side wall of the first groove 412 abut against each other, and then when the transmission part 42 continues to move axially, the locking part 41 can be driven to move to the unlocking position through the abutment between the first protrusion 421 and the first groove 412, thereby exiting the locking hole 21 and the locking notch 31, and realizing the effect of self-unlocking of the single-handle explosion-proof key unlocking mechanism. In the above process, since the first protrusion 421 can only move in the first groove 412 along the extension direction of the first groove 412, the reliability of the transmission part 42 driving the locking part 41 to move axially is ensured, circumferential rotation is avoided, and the smoothness and reliability of the movement are ensured.

[0048] At the same time, the first groove 412 also has a certain length, so that with the arrangement of the elastic member 43, when the single-handle explosion-proof key unlocking mechanism itself is unlocked and the lock cylinder is rotated to unlock, the unlocking rod 20 rotates while the locking shaft 30 does not rotate, so that the locking hole 21 and the locking notch 31 are circumferentially staggered. At this time, the locking end 411 can no longer extend into the locking hole 21 or the locking notch 31, but presses against the end surface of the locking shaft 30, and the driving motor 51 reverses and resets, driving the screw rod 52 and the transmission part 42 to move in the opposite direction for reset. At this time, the locking part 41 is pressed against the locking shaft 30 and cannot be reset, so the movement of the transmission part 42 compresses the spring, and the spring is compressed The kinetic force of the transmission part 42 is stored, and at the same time, the first protrusion 421 moves in the first groove 412; when the single-handle explosion-proof key unlocking mechanism is removed from the lock core after use, the unlocking rod 20 rotates in the opposite direction as a whole, and the locking shaft 30 remains stationary. At this time, due to the reverse rotation of the unlocking rod 20, the locking hole 21 and the locking notch 31 are realigned, and the locking end 411 can extend into the locking hole 21 and the locking notch 31, so that the locking part 41 automatically extends into the locking hole 21 and the locking notch 31 under the action of the spring, thereby realizing the automatic resetting of the single-handle explosion-proof key unlocking mechanism. The overall process is simple, reliable and effective, and no electronic detection means are required for resetting.

[0049] The cooperation between the first protrusion 421 and the first groove 412 plays the role of stopping rotation, connecting, giving way, guiding, etc., that is, the stopping and guiding role of limiting the relative rotation of the locking part 41 and the transmission part 42, the connecting role of driving the locking part 41 to move, the giving way role of providing space for the axial relative movement of the locking part 41 and the transmission part 42 when resetting, etc. In this embodiment, the unlocking lever 20, the locking part 41 and the transmission part 42 of the locking assembly 40, and the motor assembly 50 have the same axial direction, and their axes are arranged parallel to each other.

[0050] Optionally, in this embodiment, a first protrusion 421 is provided on the outer circumference of the transmission part 42, and a first groove 412 is provided on the circumference of the locking part 41. Of course, the settings can also be interchanged, that is, the first groove 412 is provided on the transmission part 42, and the first protrusion 421 is provided on the locking part 41. At the same time, a plurality of first protrusions 421 and first grooves 412 are provided, and the two are respectively arranged at intervals along the circumference of the transmission part 42 and the locking part 41, so that the force balance between the transmission part 42 and the locking part 41 can be ensured, and the reliability of the transmission between the two can be ensured.

[0051] Similar to the cooperation between the first protrusion 421 and the first groove 412, Figure 4 and Figure 6As shown, in this embodiment, a similar second limiting structure is also provided between the unlocking rod 20 and the locking part 41. Specifically, the second limiting structure includes a second protrusion 413 and a second groove 22. One of the unlocking rod 20 and the locking part 41 has the second protrusion 413, and the other of the unlocking rod 20 and the locking part 41 has the second groove 22. The second groove 22 extends along the axial direction of the motor assembly 50. The second protrusion 413 is located in the second groove 22. When the locking part 41 moves axially, the second protrusion 413 moves in the second groove 22. Similar to the functions of the first protrusion 421 and the first groove 412 mentioned above, the second protrusion 413 and the second groove 22 between the unlocking rod 20 and the locking part 41 mainly play the role of stopping rotation, guiding, limiting, and connecting, ensuring that the locking part 41 can only move along the axial direction of the unlocking rod 20, thereby preventing the locking assembly 40 from rotating relative to the unlocking rod 20 and the housing 10 as a whole, and ensuring the reliability of axial movement. At the same time, when the unlocking rod 20 rotates, the locking part 41 is driven to rotate together, so that the locking end 411 of the locking part 41 is staggered with the locking notch 31 on the locking shaft 30. In this embodiment, a second protrusion 413 is provided on the outer peripheral side of the locking part 41, and a second groove 22 is provided on the peripheral side of the unlocking rod 20. Of course, they can also be arranged interchangeably. At the same time, a plurality of second protrusions 413 and second grooves 22 are also provided, and the two are respectively arranged at intervals along the circumference of the locking part 41 and the unlocking rod 20. Since the first groove 412 and the second protrusion 413 are provided on the peripheral side of the locking part 41, it is preferred to alternately arrange the first groove 412 and the second protrusion 413 in sequence along the circumference of the locking part 41. In addition to being arranged between the unlocking rod 20 and the locking part 41, the second limiting structure can also be arranged between the transmission part 42 and the unlocking rod 20, or the above two types can be arranged at the same time.

[0052] The specific structural forms of the above-mentioned protrusions and grooves can be set as needed. This embodiment adopts a buckle and slot structure, and can also adopt a column pin, magnetic steel, pin and other structures.

[0053] It should be noted that when the single-handle explosion-proof key unlocking mechanism of this embodiment unlocks the lock cylinder and rotates, the locking shaft 30 cannot rotate due to the cooperation with the lock cylinder jack, while other components including the unlocking rod 20, the unlocking head 24, the housing 10, the locking assembly 40, and the motor assembly 50 rotate together. Therefore, the rotation in the above-mentioned stop rotation is relative to the unlocking rod 20, the unlocking head 24, the housing 10, the motor assembly 50, etc., and does not include the locking shaft 30. The shape and structure of the locking shaft 30 can be adapted to the jack, for example, Figure 8 As shown, in this embodiment, two ribs are provided on the side of the locking shaft 30 so as to cooperate with the lock cylinder.

[0054] like Figure 6 and Figure 7As shown, in this embodiment, the unlocking rod 20 is relatively fixedly connected to the housing 10, and one end of the unlocking rod 20 extends out of the housing 10, so that it can cooperate with the unlocking head 24. The side of the unlocking rod 20 has a locking hole 21, and the locking hole 21 is connected to the outer peripheral side of the unlocking rod 20. Correspondingly, the locking notch 31 is connected to the inner side of the locking shaft 30, so that the locking hole 21 can be connected to the locking notch 31. The locking hole 21 and the locking notch 31 of this embodiment are respectively set to a semi-cylindrical structure, and can also radially penetrate the corresponding components, so as to cooperate with the columnar shape of the locking end 411. There is an alignment state between the unlocking rod 20 and the locking shaft 30, in which the locking hole 21 and the locking notch 31 are circumferentially aligned, and a staggered state between the locking hole 21 and the locking notch 31. When the unlocking rod 20 and the locking shaft 30 are in the alignment state, the locking hole 21 and the locking notch 31 are butted together to form a completed cylindrical hole, and the locking end 411 can freely extend in and out. When the unlocking rod 20 and the locking shaft 30 are in the staggered state, the single-handle explosion-proof key unlocking mechanism unlocks the lock core, and the locking end 411 cannot be independently unlocked. The locking hole 21 and the locking notch 31 are re-aligned when the single-handle explosion-proof key unlocking mechanism resets itself, and the locking end 411 can automatically extend into the locking hole 21 and the locking notch 31 under the action of the elastic member 43, thereby automatically moving to the locked position to achieve automatic reset.

[0055] The unlocking head 24 of this embodiment is connected to the end of the unlocking rod 20 extending out of the housing 10. The middle part of the unlocking head 24 has a through hole, and one end of the unlocking rod 20 extends into the through hole. The unlocking head 24 is fixed to the top of the shaft of the unlocking rod 20 by a pin shaft. The outer side of the unlocking head 24 has a protruding limit ear and a multi-functional notch groove and other structures, so as to dock with the transmission parts such as the pin of the lock core. Since the single-handle explosion-proof key unlocking mechanism may cooperate with different lock cores, the unlocking head 24 adopts a detachable and replaceable setting mode, so that different unlocking heads 24 can be replaced to correspond to different lock cores to achieve customized use.

[0056] Optionally, the number of locking holes 21 and locking notches 31 can be set as needed. In this embodiment, two locking holes 21 and two locking notches 31 are provided, and the locking holes 21 and locking notches 31 are separated one by one. The locking holes 21 and locking notches 31 are spaced along the circumference of the unlocking rod 20 and the locking shaft 30. Correspondingly, two locking ends 411 are also provided in this embodiment, and they correspond one by one to the locking holes 21 and the locking notches 31. That is to say, the locking holes 21, the locking notches 31, and the locking ends 411 are arranged one by one to ensure reliable matching.

[0057] like Figure 2 As shown, in the present embodiment, since the unlocking head 24 and the locking shaft 30 are both sleeved on the outside of the unlocking rod 20, the present embodiment adopts a setting mode in which the locking shaft 30 is located between the unlocking head 24 and the housing 10 along the axial direction of the unlocking rod 20. In this way, one end of the locking shaft 30 abuts against the housing 10, and the other end abuts against the unlocking head 24, so that the axial movement of the locking shaft 30 can be limited and controlled.

[0058] In this embodiment, the unlocking rod 20 includes a first section 231, a second section 232 and a third section 233 connected in sequence along the axial direction, and the diameters of the first section 231, the second section 232 and the third section 233 are increased in sequence, wherein the first section 231 is used to install the unlocking head 24, and the unlocking head 24 can abut on the step surface between the first section 231 and the second section 232, thereby realizing the installation and positioning of the unlocking head 24; the second section 232 is used to install the locking shaft 30, and one end of the locking shaft 30 abuts on the unlocking head 24 The other end can be abutted on the housing 10, or on the step surface between the second section 232 and the third section 233. The locking hole 21 is located on the peripheral side of the second section 232, close to one end of the third section 233; the third section 233 is used to install the motor assembly 50, and the second groove 22 is arranged on the peripheral side of the third section 233. The second section 232 and the third section 233 both have a hollow structure, so that components such as the locking portion 41 can be passed through the unlocking rod 20 to achieve cooperation with the locking hole 21 and the locking notch 31.

[0059] The third section 233 of this embodiment also includes a transition section, a main section and an installation section connected in sequence, wherein the transition section is connected to the second section 232, the diameter of the transition section is larger than the diameter of the second section 232, the transition section plays a transition role, the main section is the main section, the second groove 22 is located on the side of the main section, and the installation section is used to install the motor bracket to achieve the installation and fixation of the drive motor 51. The installation section can adopt any structural form such as a bracket, a frame, a plate, etc., as long as it can achieve the installation and fixation of components such as the drive motor 51.

[0060] Of course, the specific structural form of the unlocking rod 20 is not limited to the above-mentioned method in this embodiment. It can adopt other structural forms as needed. For example, the unlocking rod 20 is directly set as an equal-diameter rod, and its end is integrally processed to form an unlocking head 24 with a specific shape structure, etc.

[0061] In this embodiment, the single-handle explosion-proof key unlocking mechanism further includes a detection component, and at least one of the unlocking rod 20, the locking component 40 and the motor component 50 cooperates with the detection component, and the detection component determines the state of the single-handle explosion-proof key unlocking mechanism by detecting at least one of the unlocking rod 20, the locking component 40 and the motor component 50. The detection components of this embodiment include two groups, one of which cooperates with the locking component 40 to detect the unlocking state of the single-handle explosion-proof key unlocking mechanism itself by detecting the locking component 40, and the other group cooperates with the unlocking rod 20 to detect the state of the unlocking cylinder of the single-handle explosion-proof key unlocking mechanism by detecting the unlocking rod 20. Of course, other detection components can also be added as needed.

[0062] Specifically, one group of detection components includes a photoelectric detection element located on one side of the locking component 40. The side of the transmission part 42 of the locking component 40 has a detection end. As the transmission part 42 moves axially, the photoelectric detection element can determine the position of the transmission part 42 by detecting the position of the detection end. When the locking component 40 is in the locked position or the unlocked position, the detection end triggers the photoelectric detection element. The photoelectric detection element detects the detection end, thereby determining the unlocking state of the single-handle explosion-proof key unlocking mechanism itself, performing corresponding information feedback and controlling the action of the drive motor 51. The photoelectric detection element can detect based on the principle of identifying color difference, such as making the slider transmission part 42 white, and the surrounding related parts such as the screw 52 black, and so on. Another group of detection components includes a magnetic element 61 and an induction element. The magnetic element 61 is connected to the locking shaft 30 and moves synchronously. This embodiment is provided with a fixing frame 90, which is fixedly connected to the locking shaft 30. The fixing frame 90 is embedded with one or more magnetic elements 61, such as Fig. 9 As shown; the sensing element is arranged in the housing 10, and the sensing element can judge the relative rotation between the locking shaft 30 and the unlocking rod 20 by detecting the position of the magnetic element 61. When the unlocking rod 20 rotates, the sensing element senses the change in the position of the magnetic element 61, thereby judging the rotation state of the unlocking rod 20 and the single-handle explosion-proof key unlocking mechanism when unlocking the lock cylinder, and performing corresponding information feedback. The magnetic element 61 of this embodiment is made of magnetic steel, and the sensing element is made of Hall element. The specific structure of the detection component is not limited to the above-mentioned method, and other structures and types of detection components can be used as needed, and only the detection of specific components can be realized, so as to reflect the state of the single-handle explosion-proof key unlocking mechanism.

[0063] In this embodiment, the single-handle explosion-proof key unlocking mechanism further includes a conductive electrode 70, a power supply code reading coil, a transmission communication module and a control board 80. The conductive electrode 70 is used to be electrically connected to an electrical lock to realize power supply and other operations, and the conductive electrode 70 is located on the side of the housing 10; the power supply code reading coil is used to supply power to the lock core and read the code for identification, and the power supply code reading coil is arranged in the housing 10; the transmission communication module is used to communicate and interact with the control end, and the transmission communication module is arranged in the housing 10; the control board 80 is electrically connected to the conductive electrode 70, the power supply code reading coil, the transmission communication module and the motor assembly 50 to control the action of the single-handle explosion-proof key unlocking mechanism. This embodiment is provided with two control boards 80, one of which is in a ring shape and is sleeved outside the unlocking rod 20. It is provided at the end of the housing 10 facing the unlocking head 24 through a cover plate, and carries components such as a power supply code reading coil, a Hall element for position detection, and a transmission communication module; the other control board 80 is located below the unlocking rod 20, and carries a photoelectric detection component for detecting the position of the transmission part 42, thereby controlling the start and stop of the driving motor 51. The two control boards 80 are connected together through a flexible circuit.

[0064] The use process of the single-handle explosion-proof key unlocking mechanism of this embodiment is as follows:

[0065] like Fig.10 As shown, when the single-handle explosion-proof key unlocking mechanism itself is not unlocked, the locking hole 21 is aligned with the locking notch 31, the locking assembly 40 is in the locked position, the locking end 411 extends into the locking hole 21 and the locking notch 31, and is stopped between the unlocking rod 20 and the locking shaft 30, so that the unlocking rod 20 and the locking shaft 30 cannot rotate relative to each other.

[0066] like Fig.11 As shown, when the single-handle explosion-proof key unlocking mechanism unlocks itself, when the operator inserts the single-handle explosion-proof key unlocking mechanism into the lock core, the feedback signal is triggered to start the drive motor 51, and the drive motor 51 drives the screw rod 52 to rotate. The screw rod 52 drives the transmission part 42 to move axially through the threaded fit, and the transmission part 42 moves in a direction away from the unlocking head 24. The movement of the transmission part 42 makes the first protrusion 421 and the first groove 412 abut against each other, thereby driving the locking part 41 to move in a direction away from the unlocking head 24, and the locking assembly 40 moves to the unlocking position. The locking end 411 exits the locking hole 21 and the locking notch 31, thereby no longer blocking the relative rotation between the locking shaft 30 and the unlocking rod 20, so that the unlocking rod 20, the housing 10 and other components can rotate, thereby driving the transmission part of the lock core to rotate to unlock the lock core. At the same time, when the screw rod 52 drives the transmission part 42 to move axially to the predetermined limit position, the photoelectric detection part detects the detection end, indicating that the locking assembly 40 moves to the position, and the control board 80 controls the drive motor 51 to stop, completing the self-unlocking. The operator then rotates the housing 10 and the unlocking rod 20 to unlock the lock cylinder.

[0067] like Fig.12 As shown, when the lock cylinder is unlocked, the locking shaft 30 does not rotate due to the cooperation with the insertion hole, and it rotates relatively with the unlocking rod 20, so that the locking hole 21 and the locking notch 31 are circumferentially staggered. At the same time, as the unlocking rod 20 rotates, the sensor detects the change in the position of the magnetic member 61, thereby determining that the lock cylinder is unlocked. At this time, the trigger signal is fed back to the drive motor 51, and the drive motor 51 starts and rotates in the reverse direction, driving the screw rod 52 to rotate, and the transmission part 42 is driven by the screw rod 52 to move in the direction close to the unlocking head 24. At this time Since the locking end 411 cannot extend into the locking hole 21 or the locking notch 31, the locking end 411 abuts against the end face of the locking shaft 30, and the locking portion 41 cannot move axially. Therefore, the movement of the transmission portion 42 will squeeze the elastic member 43, causing the elastic member 43 to be compressed. The compressed elastic member 43 generates elastic force to react on the transmission portion 42, so that the transmission portion 42 and the screw thread of the screw 52 are in a critical state of engagement. At this time, the drive motor 51 drives the screw 52 to idle, thereby achieving the goal of stopping the drive motor 51 without providing a signal.

[0068] When the single-handle explosion-proof key unlocking mechanism resets itself, the operator starts to rotate the housing 10 and the unlocking rod 20 to the initial state. At this time, the locking hole 21 and the locking notch 31 are realigned, and the locking end 411 can be inserted into the locking hole 21 and the locking notch 31 again. The locking end 411 automatically extends into the locking hole 21 and the locking notch 31 under the elastic force of the elastic member 43, and the locking assembly 40 automatically switches back to the locked position. At this time, the entire components of the single-handle explosion-proof key unlocking mechanism are reset and returned to the locked position. Fig.10 When the lock cylinder is pulled out, the same feedback signal that starts the drive motor 51 when the lock cylinder is unlocked commands the drive motor 51 to stop, thereby completing the entire unlocking action.

[0069] It should be noted that, the multiple in the above embodiments refers to at least two.
