[0031] The beneficial effects brought by the technical solution provided by the embodiment of the present application include at least:

[0032] A rotary lock may include: a lock housing, two locking claws, a lock head, two resetting elastic members, a transmission assembly and an unlocking drive member. When a pressing force (e.g., 20 kg) is applied to the cabinet door toward the inner side of the cabinet body, the lock head will move toward the inner side of the cabinet body, and the lock head column will move a small distance to disengage from the locking claw. At this time, rotating the locking claw to unlock only requires overcoming a small amount of rotational damping. No matter how much the pressing force on the cabinet door is, it will not affect the cabinet door opening after rotating to unlock. Similarly, the rotary lock will not automatically unlock after being hit by an external force.

[0033] When a large pulling force (for example, 20KG) pulls the door outward or pushes the door outward from the inside of the cabinet (for example, the user stuffs too many items into the cabinet and forcibly presses the door to close, the items will produce an extrusion force on the cabinet door toward the outside of the cabinet), the lock head will transfer the load force to the lock claw along the above-mentioned connecting line direction. Since the two lock claws are symmetrically arranged along the central axis of the opening, the load force will be decomposed into two extrusion forces on the lock claw. Since the eccentric cylindrical surface is lower eccentric, taking a lock claw (the lock claw 200 rotates in the clockwise direction when unlocking or closing) as an example, the extrusion force will produce a clockwise unlocking torque. At the same time, the extrusion force will also generate friction along the tangent direction of the eccentric cylindrical surface m1, forming a counterclockwise friction torque. When the eccentricity is less than the preset value, the friction torque generated by the extrusion force will be slightly greater than the unlocking torque generated by the extrusion force, that is, self-locking will occur. When the load force is large, it will not automatically unlock (that is, it will not unlock if you pull the door hard). At this time, if a small clockwise torque is applied to the lock claw, unlocking only requires overcoming a small amount of rotational damping and a small amount of friction torque (the remaining friction torque after balancing the unlocking torque generated by the squeezing force), so that the lock claw can be rotated clockwise to unlock. In this way, the problem of difficulty in unlocking the rotary lock under large load force is effectively solved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0060] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0063] Please refer to Figures 1 to 11 The rotary lock can be used in conjunction with a locker to open and close a door in the locker. The rotary lock can include: a lock housing 100, two locking claws 200, a lock head 300, two resetting elastic members 400, a transmission assembly 500, and an unlocking drive member 600. The lock head 300 can be connected to the door, and the lock housing 100 can be connected to the cabinet body.

[0064] The lock housing 100 in the rotary lock may have a cavity Q, and an opening a1 located at one side of the lock housing 100 and communicated with the cavity Q.

[0065] The two locking claws 200 in the rotary lock can be located in the cavity Q and can be located on both sides of the central axis L of the opening a1 in the lock housing 100. The first end D1 of each locking claw 200 can be rotatably connected to the lock housing 100, and the second end D2 of the locking claw 200 can have an eccentric cylindrical surface m1 (that is, the central axis of the eccentric cylindrical surface m1 and the rotation axis of the locking claw 200 are eccentric to a certain extent), and the central axis of the eccentric cylindrical surface m1 can be far away from the opening a1 of the lock housing 100 relative to the rotation axis of the first end D1 of the locking claw 200 (that is, the eccentric cylindrical surface m1 is a lower eccentric structure), and the first gap k1 and the second gap k2 distributed on both sides of the vertices of the two eccentric cylindrical surfaces m1 can be formed between the two eccentric cylindrical surfaces m1. Here, the first gap k1 and the second gap k2 can be distributed along the central axis L of the opening a1, and the first gap k1 can be closer to the opening a1 of the lock housing 100 relative to the second gap k2. It should be noted that the two locking claws 200 may be symmetrically arranged along the central axis L of the opening a1.

[0066] The two reset elastic members 400 in the rotary lock can be located in the cavity Q of the lock shell 100 and can correspond to the two locking claws 200 respectively. Each reset elastic member 400 can be connected to the corresponding locking claw 200 and the lock shell 100, and each reset elastic member 400 can be deformed during the rotation of the corresponding locking claw 200.

[0067] The lock head 300 in the rotary lock may have a cylindrical lock head rod 301 . When the rotary lock is in a locked state, the cylindrical surface of the lock head rod 301 and the two eccentric cylindrical surfaces m1 of the two locking claws 200 may be tangent to each other.

[0068] At least part of the transmission assembly 500 and the unlocking drive 600 in the rotary lock can be located in the cavity Q of the lock housing 100, and the transmission assembly 500 can be respectively connected to the first end D1 of the two locking claws 200 and the unlocking drive 600. The unlocking drive 600 can be configured to: drive the two locking claws 200 to rotate along the opening a1 away from the lock housing 100 and in different rotation directions through the transmission assembly 500, so that the lock rod 301 can be drawn out from between the two locking claws 200.

[0069] For example, Figures 8 to 10As shown, when the rotary lock switches from the unlocked state to the locked state, the cabinet door is pushed to drive the lock rod 301 to extend along the central axis L of the opening a1 into the first gap k1 between the two locking claws 200, and then the lock rod 301 is continuously pushed after contacting the eccentric cylindrical surface m1 of the locking claws, so that the lock rod 301 can drive the two locking claws 200 to rotate in different directions away from the opening a1 (i.e., one locking claw 200 can rotate in the clockwise direction and the other locking claw 200 can rotate in the counterclockwise direction). to); the locking claw 200 simultaneously drives the resetting elastic member 400 to deform during the rotation process; when the gap between the two locking claws 200 is larger than the diameter of the lock rod 300, the lock 300 can enter the lock housing 100 and the lock rod 300 is in the second gap k2 between the two locking claws 200; the locking claw 200 returns to the reset state under the action of the resetting elastic member 400, so that the two eccentric cylindrical surfaces m1 in the two locking claws 200 can be tangent to the cylindrical surface of the lock rod 301, and the lock is closed. At this time, the direction of the contact force between the eccentric cylindrical surface m1 of the locking claw 200 and the cylindrical surface of the lock rod 301 is the direction of the connecting line between the center of the cylinder of the lock rod 301 and the center of the eccentric cylindrical surface m1 of the locking claw 200.

[0070] Thus, when a pressing force (e.g., 20 kg) is applied to the cabinet door, the lock head 300 will move toward the cabinet body, and the lock head column 301 will move a small distance to disengage the lock claw 200. At this time, the rotation of the lock claw 200 to unlock the cabinet only needs to overcome a small amount of rotational damping. No matter how much the pressing force on the cabinet door is, it will not affect the cabinet door being opened after the rotation unlocking. Similarly, the rotary lock will not automatically unlock after being hit by an external force.

[0071] When a large pulling force (for example, 20 kg) pulls the door outward or pushes the door outward from the inside of the cabinet (for example, when the user stuffs too many items into the cabinet and forcibly presses the door to close, the items will produce an extrusion force toward the outside of the cabinet on the cabinet door), the lock head 300 will transfer the load force to the lock claw 200 along the above-mentioned connecting line direction. Since the two lock claws 200 are symmetrically arranged along the central axis L of the opening a1, the load force will be decomposed into two extrusion forces on the lock claw 200. Since the eccentric cylindrical surface m1 is lower eccentric, taking a lock claw 200 (the lock claw 200 rotates in the clockwise direction when unlocking or closing the lock) as an example, the extrusion force will generate a clockwise unlocking torque. At the same time, the extrusion force will also generate friction along the tangent direction of the eccentric cylindrical surface m1, forming a counterclockwise friction torque. When the eccentricity is less than the preset value, the friction torque generated by the extrusion force will be slightly greater than the unlocking torque generated by the extrusion force, that is, self-locking will occur. When the load force is large, the door will not automatically unlock (i.e., the door will not unlock if you pull it hard). At this time, if a small clockwise torque is applied to the lock claw 200, unlocking only requires overcoming a small amount of rotational damping and a small amount of friction torque (the remaining friction torque after balancing the unlocking torque generated by the squeezing force), and the lock claw 200 can be rotated clockwise to unlock. In this way, the problem of the difficulty of unlocking the rotary lock under large load force is effectively solved.

[0072] For example, when the rotary lock switches from the locked state to the unlocked state, the unlocking drive 600 can drive the two locking claws 200 to rotate in different directions away from the opening a1 through the transmission assembly 500 (i.e., one locking claw 200 still rotates in the clockwise direction, and the other locking claw 200 still rotates in the counterclockwise direction). When the gap between the two locking claws 200 is larger than the diameter of the lock rod 301, the lock rod can be pulled out from between the two locking claws 200. At the same time, the two locking claws 200 can return to the reset state under the action of the reset elastic member 400.

[0073] For examples, please refer to Fig.12 , Fig.12 : is a schematic diagram of the back of a rotary lock provided by an embodiment of the present application. The first end D1 of the locking claw 200 may have a rotation hole k3, and the resetting elastic member 400 may be a torsion spring, and the two ends of the torsion spring may be respectively fastened to the inner side wall of the rotation hole k3 and the lock housing 100, and the first end of the locking claw 200 may drive the torsion spring to deform during the rotation process. Or, as Figure 7 As shown, the reset elastic member 400 can be a spring sheet fixed in the cavity Q and distributed on the side of the locking claw 200 away from the opening a1. When the locking claw 200 rotates, the side of the locking claw 200 can press the spring sheet to deform the spring sheet. It should be noted that the embodiment of the present application does not specifically limit the implementation method of the reset elastic member 400, and it only needs to be able to realize the reset function of the locking claw 200.

[0074] It should be noted that if Fig.12 As shown, in order to ensure that the locking claw 200 is in the same position after each reset, the lock housing 100 may also have two supporting platforms T fixed on the inner wall of the cavity Q and corresponding to the two locking claws 200 respectively, and the supporting platforms T may be distributed on the side of the corresponding locking claw 200 facing the opening a1. In this way, after the locking claw 200 is reset, the side of the locking claw 200 may abut against the side of the corresponding supporting platform T, and the supporting platform T may provide stable support for the locking claw 200.

[0075] In the present application, the transmission assembly 500 in the rotary lock may have multiple optional implementations. The following embodiments are schematically described using two optional implementations as examples:

[0076] For the first optional implementation, please refer to Fig.13 , Fig.14 and Fig.15 , the outer side surface of the first end D1 of each locking claw 200 may have a plurality of first external teeth 201. The transmission assembly 500 may be distributed on the side of the locking claw 200 away from the opening a1 of the lock housing 100, and the transmission assembly 500 may include: two first gear components 501, a second gear component 502 and a first gear 503 respectively matched with the first external teeth 201 of the two locking claws 200, and the second gear component 502 may be matched and rotatably connected with one first gear component 501 and the first gear 503. The first gear 503 may be matched and connected with another first gear component 501 and the second gear component 502. Wherein, in the case where the number of the unlocking driving member 600 is one, the unlocking driving member 600 may be connected in transmission with the second gear component 502 or the first gear 503. For example, when the unlocking driving member 600 is in transmission connection with the second gear member 502, the unlocking driving member 600 can drive the second gear member 502 to rotate clockwise, and the second gear member 502 rotates clockwise while driving Fig.13 The first gear member 501 on the left rotates counterclockwise and the first gear 503 rotates counterclockwise; the first gear 503 rotates counterclockwise and drives Fig.13 The first gear member 501 on the right side rotates clockwise; finally, the two first gear members 501 cooperate with the two sets of first external teeth 201 to drive the two locking claws 200 to rotate in the clockwise and counterclockwise directions respectively. When the unlocking driving member 600 is connected to the first gear 503 in transmission, the unlocking driving member 600 can drive the first gear 503 to rotate counterclockwise while driving the second gear member 502 and Fig.13 The first gear component 501 on the right side rotates clockwise; finally, the two first gear components 501 cooperate with the two groups of first external teeth 201 to drive the two locking claws 200 to rotate in the clockwise and counterclockwise directions respectively.

[0077] When there are two unlocking driving members 600, the two unlocking driving members 600 can be respectively connected to the second gear member 502 and the first gear 503. In this way, the two unlocking driving members 600 can both realize the rotational drive of the locking claw 200 through the transmission assembly 500. It should be noted that when one unlocking driving member 600 is in a working state, the other unlocking driving member 600 is in a stopped working state.

[0078] In this application, if Fig.13 As shown, each first gear component 501 may include: a second gear 501a and a first incomplete gear 501b which are stacked and synchronously rotated, and the outer side surface of the first incomplete gear 501b may have multiple groups of second external teeth A1, and there may be a gap between each two adjacent groups of second external teeth A1, and the multiple groups of second external teeth A1 may be used to cooperate with multiple first external teeth 201 in the locking claw 200. In this way, the two first incomplete gears 501b on the left and right drive the two locking claws 200 to rotate toward the inside of the cavity Q, and the cabinet door is pulled out after the two locking claws 200 rotate to the right position. At this time, the two first incomplete gears 501b on the left and right continue to rotate, and when the first external teeth 201 in the locking claw 200 are opposite to the gap, the two locking claws 200 automatically rebound to the initial position under the action of the reset elastic member 400. For example, the second gear 501a may be a spur gear, the multiple groups of second external teeth A1 in the first incomplete gear 501b may be spur teeth, and the multiple first external teeth 201 cooperating with the multiple groups of second external teeth A1 may also be spur teeth.

[0079] The second gear component 502 may include: a third gear 502a and a fourth gear 502b which are stacked and synchronously rotated, the diameter and the number of teeth of the third gear 502a may be smaller than the diameter and the number of teeth of the fourth gear 502b, and the third gear 502a may be matched and connected with the first gear 503 and the second gear 501a. For example, the third gear 502a and the fourth gear 502b may be spur gears. Wherein, when the unlocking drive 600 is transmission-connected with the second gear component 502, the unlocking drive 600 may be matched and connected with the fourth gear 502b in the second gear component 502.

[0080] Optional, such as Fig.13 and Fig.14As shown, when the number of unlocking driving members 600 is one, the unlocking driving member 600 may be the first unlocking driving member 600a or the second unlocking driving member 600b. When the number of unlocking driving members 600 is two, the two unlocking driving members 600 may be the first unlocking driving member 600a and the second unlocking driving member 600b, respectively, and when the first unlocking driving member 600a is in a working state, the second unlocking driving member 600b may be separated from the first gear 503. The first unlocking driving member 600a may include: a first driving motor 601 and a first auxiliary transmission member 602, the first driving motor 601 and the first auxiliary transmission member 602 may be both located in the cavity Q of the lock housing 100, and the first auxiliary transmission member 602 may be respectively connected to the output shaft of the first driving motor 601 and the fourth gear 502b. In this way, when the first driving motor 601 is working, it drives the fourth gear 502b to rotate clockwise through the first auxiliary transmission member 601, thereby realizing the clockwise rotation of the third gear 502a.

[0081] The second unlocking drive member 600b may include: a mechanical unlocking rod 603, a second auxiliary transmission member 604 and a limiting member 605. Part of the mechanical unlocking rod 603 and the second auxiliary transmission member 604 may be located in the cavity Q, and another part of the mechanical unlocking rod 603 may be located outside the cavity Q of the lock housing 100. The second auxiliary transmission member 604 may be respectively connected to the mechanical unlocking rod 603 and the first gear 503. The limiting member 605 may be used to limit the mechanical unlocking rod 603 at a target position before driving the second auxiliary transmission member 604 to move. Among them, the mechanical unlocking rod 603 may be configured to: drive the first gear 503 to rotate through the second auxiliary transmission member 604 during the sliding process relative to the lock housing 100. In this way, when the mechanical unlocking rod 603 slides, it can drive the first gear 503 to rotate counterclockwise through the second auxiliary transmission member 604, thereby driving Fig.10 The first gear component 501 on the right side rotates clockwise and the second gear component 502 on the left side rotates clockwise, and finally the two locking claws 200 are driven to rotate by the first gear component 501 on the left side and the first gear component 501 on the right side. In addition, when the first driving motor 601 fails to start due to power failure, the user can conveniently unlock the rotary lock through the mechanical unlocking rod 603, which increases the flexibility of the rotary lock. Here, Fig.15 As shown, the side of the lock housing 100 has a first opening a2, and another part of the mechanical unlocking rod 603 can extend out of the cavity Q of the lock housing 100 through the first opening a2.

[0082] In this application, if Fig.15As shown, the first auxiliary transmission member 602 may include: a first bevel gear B1 and a first spur gear B2 which are stacked and synchronously rotated, and a second bevel gear B3, the second bevel gear B3 may be sleeved on the output shaft of the first drive motor 601 and may be matched with the first bevel gear B1, and the first spur gear B2 may be matched with the fourth gear 502b. In this way, when the first drive motor 601 drives the second bevel gear B3 to rotate counterclockwise, it also drives the first bevel gear B1 to rotate counterclockwise, and then drives the fourth gear 502b to rotate clockwise when the first spur gear B2 rotates counterclockwise.

[0083] The second auxiliary transmission member 604 may include: a plurality of third external teeth C1 fixed to the side of the mechanical unlocking rod 603 and cooperating with the first gear 503. The mechanical unlocking rod 603 may be configured to drive the first gear 503 to rotate through the plurality of third external teeth C1 during the process of extending out of the cavity Q relative to the lock housing 100.

[0084] For example, Fig.14 and Fig.15 As shown, the mechanical unlocking rod 603 may include: a first unlocking rod 603a, a transition connecting rod 603b and a second unlocking rod 603c, one end of the first unlocking rod 603a is located outside the cavity Q through the first opening a2, one end of the second unlocking rod 603c can be abutted against the lock housing 100, the first unlocking rod 603a and the second unlocking rod 603c are arranged in parallel and the first unlocking rod 603a is close to the first gear 503 relative to the second unlocking rod 603c, and the two ends of the transition connecting rod 603b are fixedly connected to the other end of the first unlocking rod 603a and the other end of the second unlocking rod 603c, respectively. The stopper 605 may include: a first abutment platform 605a and a first elastic element 605b, the first abutment platform 605a may be located on the side of the first gear 503 away from the first opening a2, the first abutment platform 605a may contact the side of the transition connecting rod 603b away from the first unlocking rod 603a and the second unlocking rod 603c, the first elastic element 605b may be sleeved on the second unlocking rod 603c and the two ends thereof respectively abut against the first abutment platform 605a and the lock housing 100. Here, a plurality of third external teeth C1 may be provided on the side of one end of the first unlocking rod 603a.

[0085] For example, Fig.15 As shown, the lock housing 100 may have a second abutment platform D3 fixed in the cavity Q, and one end of the second unlocking rod 603c may abut against the second abutment platform D3.

[0086] The second optional implementation method is Fig.16 and Fig.17As shown, the outer side surface of the first end D1 of each locking claw 200 may have a first abutment portion 202; the transmission assembly 500 may be distributed on the side of the two locking claws 200 away from the opening of the lock housing 100, and the transmission assembly 500 may include: an unlocking pusher 504 and a first unlocking swing rod 505, and the first end D4 of the first unlocking swing rod 505 may be rotatably connected to the lock housing 100. One end of the unlocking pusher 504 may have two push rods 504a that respectively contact the two first abutment portions 202 of the two locking claws 200, and the other end of the unlocking pusher 504 may contact the middle part of the first unlocking swing rod 505. In the case where the number of the unlocking driving member 600 is one, the unlocking driving member 600 cooperates with the second end of the first unlocking swing rod 505 or is tightly connected with the first end D4 of the first unlocking swing rod 505. In the case where there are two unlocking driving members 600, the two unlocking driving members 600 are respectively matched with the second end of the first unlocking rocker 505 and are fastened to the first end D4 of the first unlocking rocker 505. The unlocking driving member 600 is configured to: in the process of driving the second end of the first unlocking rocker 505 to rotate, the two push rods 504a in the unlocking push member 504 respectively push the two locking claws 200 to rotate in different directions away from the opening a1. Here, the other end of the unlocking push member 504 can have a first pin X1 that is in contact with the middle part of the first unlocking rocker 505, that is, in the process of switching from the locked state to the unlocked state, the unlocking driving member 600 drives the first unlocking rocker 505 to rotate in the clockwise direction, and can push the two push rods 504a in the unlocking push member 504 to move in the direction close to the opening a1 through the first pin X1, thereby pushing the first end D1 of the locking claw 200 to rotate, so that Fig.16 The locking claw 200 on the left side can rotate in a clockwise direction, and the locking claw 200 on the right side can rotate in a counterclockwise direction.

[0087] For example, Figures 18 to 22 As shown, the unlocking push member 504 may include: a first support rod 504b, a second support rod 504c and two push rods 504a, one end of the two push rods 504a is fixedly connected to the two ends of the first support rod 504b respectively, one end of the second support rod 504c is fixedly connected to the second support rod 504c, and the other end of the second support rod 504c can contact the middle part of the first unlocking swing rod. Among them, the extension direction of the push rod 504a can intersect with the extension direction of the first support rod 504b, and the extension direction of the second support rod 504c can intersect with the extension direction of the first support rod 504b. For example, the second support rod 504c can be perpendicular to the first support rod 504b and parallel to the push rod 504a, and the two push rods 504a and the first support rod 504b can be surrounded by a U-shaped frame.

[0088] For example, the lock housing 100 may have two first guide members D5 fixed in the cavity Q, and the two first guide members D5 may be slidably connected to the two push rods 504a, respectively. In this way, the first guide member D5 may provide a good guiding effect for the forward and backward movement of the push rod 504a, ensuring the stable contact between the push rod 504a and the lock claw 200.

[0089] Optional, such as Figures 16 to 22 As shown, the outer side surface of the first end D1 of each locking claw 200 may also have a second abutment portion 203; the rotary lock may also include: an anti-loosening component 700 installed in the cavity Q, a second unlocking rocker 800 and an anti-loosening resetting elastic member 900, one end of the anti-loosening component 700 may have two anti-loosening rods 701 that cooperate with the two second abutment portions 203 in the two locking claws 200, and the other end of the anti-loosening component 700 may have an abutment column 702. The second unlocking rocker 800 may have a first rod 801 and a second rod 802 that are cross-arranged, one end of the first rod 801 may be rotatably connected to the first end D4 of the first unlocking rocker 505 through a synchronous transmission member 1000, the other end of the first rod 801 may be fixedly connected to one end of the second rod 802, and the other end of the first rod 801 may be located on a side of the abutment column 702 close to the locking claw 200 and may contact the abutment column 702. The other end of the second rod 802 can extend to the side of the two locking claws 200 close to the opening a1 to cooperate with the lock rod 301 during the locking process of the rotary lock. In this way, the anti-loosening rod 701 can lock the lock claw 200 after abutting against the second abutting portion 203 of the lock claw 200, effectively solving the problem of accidental unlocking of the rotary lock under external force. And in the process of switching the rotary lock from the unlocked state to the locked state, the lock rod 301 enters the cavity Q from the opening a1 and first contacts the other end of the second rod 802 in the second unlocking rocker 800, and pushes the second unlocking rocker 800 to move in the direction away from the opening a1, and at the same time drives the anti-loosening component 700 to move in the direction away from the opening a1 through the cooperation with the abutting column 702, so as to ensure that the anti-loosening rod 701 will not affect the rotation of the lock claw 200; The other end of the rod 802 separates and contacts the locking claw 200 and then continues to move into the cavity. When the gap between the two locking claws 200 is larger than the diameter of the lock rod 300, the lock head 300 is able to enter the lock housing 100 and the lock rod 300 is in the second gap k2 between the two locking claws 200. The locking claw 200 returns to the reset state under the action of the reset elastic member 400, so that the two eccentric cylindrical surfaces m1 in the two locking claws 200 can be tangent to the cylindrical surface of the lock rod 301, thereby achieving locking.

[0090] The anti-loosening reset elastic member 900 can be located on a side of the anti-loosening member 700 close to the opening a1, and the two ends of the anti-loosening reset elastic member 900 can be connected to the anti-loosening member 700 and the lock housing 100 respectively. In this way, when the rotary lock is switched to the locked state, the anti-loosening reset elastic member 900 is stretched as the anti-loosening member 700 moves; after the rotary lock is switched to the locked state, the anti-loosening member 700 can move to the anti-loosening rod 701 and the second abutment portion 203 of the lock claw 200 under the rebound force of the anti-loosening reset elastic member 900. Here, the anti-loosening reset elastic member 900 can be a spring. For example, the lock housing 100 can have a support column Z1 fixed in the cavity Q, and one end of the anti-loosening reset elastic member 900 can be tightly connected to the support column Z1.

[0091] For example, the other end of the second rod 802 may have a bent head 802a, and one end of the bent head 802a connected to the second rod 802 is closer to the opening a1 than the other end of the bent head 802a. In this way, the lock rod 301 can cooperate with the bent head 802a in the second rod 802 to facilitate pushing the second unlocking swing rod 800.

[0092] It should be noted that the first abutting portion 202 and the second abutting portion 203 in the locking claw 200 can both be limiting grooves.

[0093] For example, the anti-loosening component 700 may include: a third support rod 703, a fourth support rod 704 and two anti-loosening rods 701, one end of the two anti-loosening rods 701 is fixedly connected to the two ends of the third support rod 703, one end of the fourth support rod 704 is fixedly connected to the third support rod 703, and the other end of the fourth support rod 704 may have an abutment column 702. Wherein, the extension direction of the anti-loosening rod 701 may intersect with the extension direction of the third support rod 703, and the extension direction of the fourth support rod 704 may intersect with the extension direction of the third support rod 703. For example, the fourth support rod 704 may be perpendicular to the third support rod 703 and may be arranged in parallel with the anti-loosening rod 701, and the two anti-loosening rods 701 and the third support rod 703 may be surrounded by a U-shaped frame. Here, the two anti-loosening rods 701 may be arranged in parallel. In addition, the other end of the anti-loosening reset elastic member 900 may be fastened to the third support rod 703.

[0094] For example, Fig.18 and Fig.19 As shown, the lock housing 100 may have two second guide members D6 fixed in the cavity Q, and the two second guide members D6 may be slidably connected to the two anti-loosening rods 701 respectively.

[0095] In the embodiments of the present application, Fig.19 and Fig. 20As shown, the synchronous transmission member 1000 may include: a plurality of first bevel teeth 1100 fixedly connected to the first end D4 of the first unlocking rocker 505, a plurality of second bevel teeth 1200 fixedly connected to one end of the first rod 801, and a planetary bevel gear 1300 connected to the lock housing 100. The plurality of first bevel teeth 1100 and the plurality of second bevel teeth 1200 may be rotatably connected to the planetary bevel gear 1300.

[0096] For example, the planetary bevel gear 1300 may include: a planetary frame 1301 and a planetary bevel gear body 1302, wherein the planetary frame 1301 may be fixed on the lock housing 100, and the planetary bevel gear body 1302 may be rotatably connected to the planetary frame 1301. The plurality of first bevel teeth 1100 and the plurality of second bevel teeth 1200 may be rotatably connected to the planetary bevel gear body 1302. The first unlocking rocker 505 with a fan-shaped bevel gear, the planetary bevel gear 1300, and the first rod 801 with a fan-shaped bevel gear form a differential gear train, and the number of complete teeth of the fan-shaped bevel gear is equal to the number of teeth of the planetary bevel gear, so that the first unlocking rocker 505 with a fan-shaped bevel gear and the first rod 801 with a fan-shaped bevel gear can rotate at the same speed, but in opposite directions. For example, when unlocking, under the action of the differential gear train, the first unlocking rocker 505 and the second unlocking rocker 800 rotate in opposite directions, so that the anti-loosening rod 701 first disengages from the limiting groove of the locking claw 200, and then the two push rods 504a push the two locking claws 200 to rotate and unlock. It should be noted that the process of locking and closing the rotary lock is opposite to the above process, which will not be repeated here.

[0097] Optional, such as Fig.16 and Fig.19 As shown, when the number of unlocking driving members 600 is one, the unlocking driving member 600 may be the third unlocking driving member 600c or the fourth unlocking driving member 600d. When the number of unlocking driving members 600 is two, the two unlocking driving members 600 may be the third unlocking driving member 600c and the fourth unlocking driving member 600d respectively. Wherein, the third unlocking driving member 600c includes: a second driving motor 606 and a third auxiliary transmission member 607, the second driving motor 606 and the third auxiliary transmission member 607 may be located in the cavity Q, the third auxiliary transmission member 607 may be connected to the output shaft of the second driving motor 606, and is used to cooperate with the second end of the first unlocking swing rod 505. In this way, the cooperation of the second driving motor 606 and the third auxiliary transmission member 607 can drive the second end of the first unlocking swing rod 505 to rotate clockwise, thereby pushing the unlocking push member 504 to move forward, and realizing automatic unlocking. For example, the second driving motor 606 may be a reduction motor.

[0098] The fourth unlocking driving member 600 includes: a mechanical unlocking swing rod 608, one end of which can be fixedly connected to the first end D4 of the first unlocking swing rod 505. In this way, the clockwise rotation of the mechanical unlocking swing rod 608 can also drive the second end of the first unlocking swing rod 505 to rotate clockwise, thereby pushing the unlocking pusher 504 to move forward and realize automatic unlocking. Here, the mechanical unlocking swing rod 608 can be arranged crosswise with the first unlocking swing rod 505.

[0099] In the present application, the third auxiliary transmission member 607 may include: a third bevel gear 607a, a fourth bevel gear 607b and a second spur gear 607c which are stacked and synchronously rotated and connected to each other, and a third spur gear 607d, wherein the third bevel gear 607a may be sleeved on the output shaft of the second drive motor 606 and cooperate with the fourth bevel gear 607b, and the second spur gear 607c may cooperate with the third spur gear 607d and rotated and connected. Among them, the side of the third spur gear 607d may have a pin Z2 for cooperating with the second end of the first unlocking swing rod 505. In this way, during the unlocking process of the rotary lock, the second drive motor 606 drives the third bevel gear 607a to rotate counterclockwise, and drives the fourth bevel gear 607b and the second spur gear 607c to rotate counterclockwise synchronously, and then drives the third spur gear 607d to rotate clockwise, and the second end of the first unlocking swing rod 505 is driven to rotate clockwise through the pin Z2, so as to push the unlocking pusher 504 to move forward.

[0100] In the embodiment of the present application, the rotary lock may further include: a control component 1500 and a travel switch 1400. The travel switch 1400 may be fixed in the cavity Q and located on the side of the first unlocking rocker 505 away from the lock pusher 504. The second drive motor 606 and the travel switch 1400 may be electrically connected to the control component 1500. In this way, after the third spur gear 607d rotates clockwise to push the unlocking pusher 504 forward through the pin Z2, the pin Z2 rotates to the travel switch 1400 and can contact the travel switch 1400. After detecting the position signal of the pin Z2, the travel switch 1400 can send the signal to the control component 1500. The control component 1500 can control the second drive motor 606 to stop rotating according to the signal, thereby avoiding the position error when the second drive motor 606 stops rotating and causing the switch to be locked in place. In addition, during the process of locking, the first unlocking swing rod 505 cannot contact the pin Z2 within the swingable range, and cannot drive the second drive motor 606 to reverse through the third spur gear 607d with the pin Z2, the fourth bevel gear 607b and the second spur gear 607c and the third bevel gear 607a that are synchronously rotated. This can prevent the lock head from driving the second drive motor 606 to reverse and be damaged when the lock is violently locked. It can also prevent the manual unlocking by rotating the first unlocking swing rod 505 through the mechanical unlocking swing rod 608, resulting in the influence of the second drive motor 606, resulting in too large torque and unable to unlock. In the embodiment of the present application, the control component 1500 is a control circuit, and can also be a printed circuit board. When the control component 1500 is a printed circuit board, the control circuit can be set on the printed circuit board.

[0101] It should be noted that the start and stop of the second drive motor 606 can be controlled by the terminal device or the switch component through the communication connection between the terminal device and the control component 1500, and / or a switch component electrically connected to the control component 1500 is set on the locker.

[0102] Optional, such as Fig. 22 As shown, the lock housing 100 may have an abutment platform D7 fixed in the cavity Q, and the rotary pin may also include: a spring-loaded door column T1 and an elastic element T2, one end of the spring-loaded door column T1 may abut against the abutment platform D7, and the other end of the spring-loaded door column T1 may extend out of the cavity Q of the lock housing 100. The elastic element T2 may be sleeved on the spring-loaded door column T1 and its two ends may contact the spring-loaded door column T1 and the abutment platform D7 respectively. Among them, the part of the spring-loaded door column T1 extending out of the cavity Q may be used to cooperate with the cabinet door, and in the process of closing the cabinet door, the spring-loaded door column T1 may be driven to shrink into the cavity Q and drive the elastic element T2 to compress. In this way, after the lock rod 301 and the lock claw 200 are released, the cabinet door may be ejected under the joint action of the spring-loaded door column T1 and the elastic element T2, thereby improving the convenience of using the rotary lock.

[0103] For example, the outer side surface of the spring post T1 may have a first annular supporting plate T11 and a second annular supporting plate T12 that are relatively arranged, the elastic element T2 may be located between the first annular supporting plate T11 and the second annular supporting plate T12 and its two ends may contact the first annular supporting plate T11 and the second annular supporting plate T12 respectively, and the side of the second annular supporting plate T12 facing away from the first annular supporting plate T11 may contact the abutment platform D7.

[0104] The embodiment of the present application also provides a locker, which may include: a cabinet door, a cabinet body (not shown in the figure), and a rotary lock, wherein a lock head 300 in the rotary lock may be installed on the cabinet door, and a lock shell 100 in the rotary lock may be installed in the cabinet body. In this way, the cabinet door and the cabinet body are opened or closed by the cooperation between the lock head 300 and the lock claw 200 in the lock shell 100.

[0105] Optional, such as Fig.23 and Fig.24 As shown, the lock housing 100 in the rotary lock may include: a base 101 and an upper cover 102 that are interlocked, the base 101 may have a connecting column 101a, and the first end D1 of the lock claw 200 may have a rotating hole k3 that is rotatably connected to the connecting column 101a. Here, the lock claw 200, the reset elastic member 400, the transmission assembly 500 and the unlocking drive member 600 can all be installed on the base 101. As for the installation method of the lock housing 100 and the cabinet, the embodiment of the present application takes the following three optional implementation methods as examples for schematic description:

[0106] In a first optional implementation, the connecting column 101a in the base 101 may have a first fastening hole k4, the upper cover 102 in the lock shell 100 may have a first through hole k5 connected to the first fastening hole k4, and the cabinet may have a second through hole (not shown in the figure) connected to the first fastening hole k4. The rotary lock may also include: a first fastener 2000, one end of which may pass through the second through hole in the cabinet and the first through hole k5 in the upper cover 102 in sequence and be fastened to the first fastening hole k4. In this way, the load force and tensile force received by the lock claw 200 can be decomposed into the first fastener 2000 that fixes the lock shell 100, and then directly act on the cabinet, and the lock shell 100 itself will basically not be affected by the load force, so as to avoid the undesirable phenomenon of deformation and damage of the lock shell 100 under the action of a large tensile force (for example, 450KG). For example, the first fastener 2000 may be a locking bolt.

[0107] In a second optional implementation, the base 101 may have a second fastening hole k6, and the cabinet may have a third through hole connected to the second fastening hole k6. The rotary lock may also include: a second fastener 3000, one end of which passes through the third through hole in the cabinet in turn and is fastened to the second fastening hole k6. For example, the second fastener 3000 may be a locking bolt.

[0108] In a third optional implementation, the connecting column 101a in the base 101 may have a first fastening hole, the upper cover 102 in the lock shell may have a first through hole k5 connected to the first fastening hole k4, and the cabinet may have a second through hole k6 connected to the first fastening hole k4. The rotary lock may also include: a first fastener 2000, one end of which may pass through the second through hole k6 in the cabinet and the first through hole k5 in the upper cover 102 in sequence and be fastened to the first fastening hole k4. In this way, the load force and tensile force on the lock claw 200 can be decomposed to the first fastener 2000 that fixes the lock shell 100, and then directly act on the cabinet, and the lock shell 100 itself will basically not be affected by the load force, thereby avoiding the undesirable phenomenon of deformation and damage of the lock shell 100 under the action of a large tensile force (for example, 450KG).

[0109] At the same time, as a further auxiliary connection, the base 101 may also have a second fastening hole k6, and the cabinet may have a third through hole connected to the second fastening hole k6. The rotary lock may also include: a second fastener 3000, one end of which passes through the third through hole in the cabinet in turn and is fastened to the second fastening hole k6.

[0111] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
