[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on November 27, 2023, with application number 2023115984534 and title “Lock,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present disclosure belongs to the technical field of locks, and particularly relates to a lock. Background Art

[0004] The lock is primarily designed to be installed on a door frame, locking the door by inserting a bolt on the door body into a recess in the lock. The lock comprises a lock body, a latch, a brake shaft, and a control assembly. The latch is mounted on a main shaft and can rotate about it. The brake shaft and latch cooperate to enable or disable rotation of the latch about the main shaft. The brake shaft is limited by a slider. When the slider gives way to the brake shaft, the latch can rotate about the main shaft. Whether the slider gives way to the brake shaft depends on the positional relationship between the slider and the brake. The control assembly is used to drive the brake, and this movement can change the positional relationship between the slider and the brake.

[0005] Specifically, the lock is divided into two situations according to whether the lock buckle can rotate around the main axis after power is turned on and locked; power is turned on and locked and unlocked by power off. Among them, power is turned on and unlocked by power off means that the lock buckle can rotate and the lock can be opened after power is turned on, and the lock buckle cannot rotate and the lock cannot be opened after power is turned off.

[0006] In the prior art, as shown in FIG1 , a lock body is connected to a sleeve 01 , which is provided with a plurality of ball grooves, in which balls are provided. The annular wall of a brake ring 02 (i.e., the aforementioned brake member) is provided with a plurality of arc grooves. When the brake ring 02 is adjusted so that the arc grooves of the brake ring 02 come into contact with the balls, the large-diameter section of the movable pull bolt 03 can slide into the sleeve 01 , and the slider can move toward the direction close to the brake ring 02 . When the brake ring 02 is adjusted so that the annular wall of the brake ring 02 comes into contact with the balls, the large-diameter section of the movable pull bolt 03 is blocked by the balls, and the slider cannot move toward the direction close to the brake ring 02 . The prior art has the disadvantage of being inconvenient to adjust, and the presence of the balls easily leads to a stuck situation during the adjustment process. Summary of the Invention

[0034] Preferred embodiments of the present disclosure

[0035] In order to better understand the purpose, structure and function of the present invention, a lock of the present invention is further described in detail below with reference to the accompanying drawings.

[0036] Depending on whether the lock catch can rotate around the main axis after power is applied, the lock can be divided into two situations: power-on unlocking and power-off locking, and power-on locking and power-off unlocking. Taking unlocking after power is applied as an example, after power is applied, the brake shaft blocks the rotation direction of the lock catch, the slider blocks the movement direction of the brake shaft, and the brake component (such as the brake ring) blocks the movement direction of the slider. Therefore, the slider cannot move to make way for the movement of the brake shaft, and the brake shaft cannot move to make way for the rotation of the lock catch, and the lock catch cannot rotate, which means that the lock cannot be opened after power is applied. After power is applied, the control component controls the rotation of the brake ring. The rotation of the brake ring changes the relative position between the brake ring and the slider. At this time, the slider can move toward the direction close to the brake ring to make way for the movement of the brake shaft. The brake shaft can move and the lock catch can rotate, so the lock can be opened after power is applied.

[0037] As shown in Figures 2, 3 and 4, a lock according to an embodiment of the present disclosure is shown, comprising a lock body, a lock catch 11, a connecting rod 04, a slider 09, a slider return spring, a brake shaft assembly 08 and a control assembly; wherein the lock catch 11 cooperates with the brake shaft assembly 08, and when the lock catch 11 is subjected to the force of the lock tongue, it will have a tendency to rotate. Along the rotation direction of the lock catch 11 when unlocking, the brake shaft assembly 08 is located in front of the movement direction of the lock catch 11. Therefore, when the lock catch 11 is subjected to the force of the lock tongue and has a tendency to rotate, the lock catch 11 will generate a corresponding force on the brake shaft assembly 08, and the brake shaft assembly 08 has a tendency to move under this force; whether the brake shaft assembly 08 can move depends on the slider 09 and the brake ring 02. When the slider 09 can move in the direction close to the brake ring 02, that is, the slider can make way for the movement of the brake shaft assembly, the brake shaft assembly 08 can move, and the lock catch can rotate.

[0038] From the above, it can be seen that whether the brake shaft assembly 08 can move depends on the slider 09 and the brake ring 02. Specifically, the control assembly is used to control the movement of the connecting rod 04 in the lock body. The connecting rod 04 can be reset after the force of the control assembly disappears. The connecting rod 04 cooperates with the brake ring 02. The movement of the connecting rod 04 can drive the brake ring 02 to rotate. The rotation of the brake ring will cause the slider to change from being able to move in the direction close to the brake ring to being unable to move in the direction close to the brake ring, or from being unable to move in the direction close to the brake ring to being able to move in the direction close to the brake ring.

[0039] This embodiment also includes a base 05 connected to the lock body, the base 05 is connected to the brake ring 02, a non-circular groove is provided in the brake ring 02, the part of the slider 09 close to the brake ring 02 is a matching block 091 matching the non-circular groove, and the rotation of the brake ring 02 can change the relative position of the matching block 091 and the non-circular groove.

[0040] Specifically, in this embodiment, as shown in Figures 6, 7, 9 and 10, a non-circular groove is provided in the brake ring 02, and the part of the slider 09 close to the brake ring 02 is a matching block 091 that matches the non-circular groove of the brake ring 02. Therefore, when the matching block 091 is aligned with the non-circular groove, the matching block 091 can enter the non-circular groove. At this time, under the action of the lock buckle 11, the slider 09 can move in the direction close to the brake ring 02, so that the matching block 091 can enter the non-circular groove and the lock can be opened; when the matching block 091 is not aligned with the non-circular groove, under the action of the lock buckle 11, the matching block 091 cannot enter the non-circular groove, and the lock cannot be opened.

[0041] Again, the connecting rod 04 cooperates with the brake ring 02 so that the movement of the connecting rod 04 can drive the brake ring 02 to rotate, thereby changing the position of the non-circular groove. The change in the position of the non-circular groove will cause the relative position of the matching block 091 and the non-circular groove to change, thereby changing the state of the lock, for example, from an unlocked state to a locked state, or from a locked state to an unlocked state.

[0042] Among them, the control component includes a solenoid and a movable core shaft arranged in the solenoid. The solenoid is used to generate a magnetic field, and the movable core shaft is used to move under the action of the magnetic field to drive the connecting rod 04 to move; a connecting rod reset spring 07 is provided between the connecting rod 04 and the lock body. The connecting rod reset spring 07 is used to drive the connecting rod to reset after the magnetic field disappears, and the connecting rod reset drives the brake ring to reset.

[0043] Specifically, the solenoid can generate a magnetic field after being energized. The moving core shaft moves under the action of the magnetic field to push the movement of the connecting rod 04, thereby realizing the rotation of the brake ring 02; when the power is cut off, the connecting rod 04 is reset under the action of the connecting rod reset yellow 07, and the reset of the connecting rod 04 drives the brake ring 02 to rotate again, thereby realizing the reset of the brake ring 02.

[0044] Taking the example of the situation where the force of the control component disappears and the matching block 091 is aligned with the non-circular groove, the lock is in a state that can be opened. After power is turned on, the connecting rod 04 moves to drive the brake ring 02 to rotate. The brake ring 02 rotates and the matching block 091 is no longer aligned with the non-circular groove. At this time, the lock cannot be opened, that is, the corresponding lock is locked when power is turned on and unlocked when power is turned off; taking the example of the situation where the force of the control component disappears and the matching block 091 is not aligned with the non-circular groove, the lock is in a state that cannot be opened. After power is turned on, the connecting rod 04 moves to drive the brake ring 02 to rotate. The relative position of the brake ring 02 and the matching block 091 of the non-circular groove changes. When the connecting rod 04 moves to the extreme position, the brake ring 02 no longer rotates, and the matching block 091 is aligned with the non-circular groove. At this time, the lock can be opened, that is, the corresponding lock is unlocked when power is turned on and locked when power is turned off.

[0045] The disclosed embodiment changes the relative position of the matching block 091 and the non-circular groove by adjusting the brake ring 02, thereby changing the state of the lock, which has the advantage of convenient adjustment.

[0046] In a specific embodiment, as shown in Figures 7 and 10, an adjustment block 021 is connected to the outer ring wall of the brake ring 02, and a groove 022 is provided on the adjustment block 021; the connecting rod 04 is connected to a protrusion 061 that cooperates with the groove 022, and the protrusion 061 extends into the groove 022 to drive the brake ring 02 to rotate.

[0047] In this embodiment, connecting rod 04 drives brake ring 02 to rotate by cooperating with groove 022 and protrusion 061. Specifically, adjustment block 021 is connected to the outer ring wall of brake ring 02. Adjustment block 021 is provided with groove 022, and connecting rod 04 is connected with protrusion 061. Protrusion 061 extends into groove 022. When connecting rod 04 moves, protrusion 061 pushes adjustment block 021, thereby rotating adjustment block 021 and brake ring 02.

[0048] In a specific embodiment, there are two grooves 022. When the protrusion 061 is located in one of the grooves 022, the matching block 091 can enter the non-circular groove; when the protrusion 061 is located in the other groove 022, the matching block 091 cannot enter the non-circular groove.

[0049] In this embodiment, two adjustment grooves are provided to facilitate adjustment of the state of the lock, for example, adjusting the lock to open when power is on, or adjusting the lock to open after power is off.

[0050] Specifically, when the connecting rod extends into one of the grooves, the mating block can enter the non-circular groove; when the connecting rod extends into the other groove, the mating block cannot enter the non-circular groove. Taking the example of the case where the mating block can enter the non-circular groove when the connecting rod extends into one of the grooves, the lock in this case is of the power-off unlock type. When power is applied, the connecting rod moves, driving the brake ring to rotate. The rotation of the brake ring changes the relative position of the mating block and the non-circular groove, that is, the lock is locked when power is applied. Correspondingly, when the connecting rod extends into the other groove, the mating block cannot enter the non-circular groove, corresponding to the lock type of power-off lock and power-on unlock.

[0051] In this embodiment, the specific type of the lock can be changed by adjusting the protrusion 061 to be located in different grooves 022, that is, the lock can be adjusted from power-off locked and power-on unlocked to power-off unlocked and power-on locked, or the lock can be adjusted from power-off unlocked and power-on locked to power-off locked and power-on unlocked.

[0052] In a specific embodiment, as shown in Figure 2, the connecting rod 04 is connected to the adjusting member 06 through two fasteners. As shown in Figure 11, the protrusion 061 is provided on the adjusting member 06, and an arc groove 062 is provided at one of the fasteners on the adjusting member 06. The arc groove 062 takes the rotating axis of the other fastener as the center; each groove 022 on the adjusting block 021 is provided with an avoidance groove for the protrusion 061 to leave the groove 022.

[0053] In this embodiment, the connecting rod 04 is connected to the adjusting member 06 by two fasteners, and the protrusion 061 is set on the adjusting member 06, so that the movement of the connecting rod 04 can drive the movement of the adjusting member 06; the protrusion 061 on the adjusting member 06 extends into the groove 022 to promote the rotation of the brake ring 02.

[0054] As shown in FIG11 , an arcuate groove 062 is provided at one of the fasteners on the adjusting member 06 . The arcuate groove 062 is centered on the rotation axis of the other fastener. Therefore, when it is necessary to move the protrusion 061 from one groove 022 to another groove 022 , the fastener is loosened and the adjusting member 06 is rotated so that the adjusting member 06 leaves the groove 022 through the escape groove. The brake ring 02 and the adjusting member 06 are then rotated so that the protrusion 061 of the adjusting member 06 passes through the other escape groove and extends into the other groove 022 . Finally, the fastener is adjusted. As an alternative, three adjusting blocks 021 can be provided, with a groove 022 formed between two adjacent adjusting blocks 021 . This arrangement does not require a separate escape groove.

[0055] The state of the lock can be adjusted by arranging the adjusting member 06 , the arc-shaped slot 062 and the two grooves 022 .

[0056] In a specific embodiment, as shown in Figure 6, the base 05 includes a bottom plate 051 and side plates 052 located on both sides of the bottom plate 051, each side plate 052 is fixedly connected to the lock body, and the brake ring is rotatably connected to the bottom plate; as shown in Figure 8, two indicator holes 121 are provided on the bottom plate 051, and the brake ring 02 is fixedly connected to the state adjustment member 12, and the head of the state adjustment member 12 extending out of the bottom plate 051 has a matching groove that matches the indicator hole 121. When the matching groove is aligned with one of the indicator holes 121, the matching block 091 can enter the non-circular groove; when the matching groove is aligned with the other indicator hole 121, the matching block 091 cannot enter the non-circular groove.

[0057] In this embodiment, the base 05 includes a bottom plate 051 and a side plate 052, and the base 05 is fixed to the lock body through the side plate 052; two indicator holes 121 are provided on the bottom plate 051, and the brake ring 02 is connected to the state adjustment part 12, and the matching groove of the state adjustment part 12 and the indicator hole 121 cooperate to facilitate the adjustment of the state of the lock.

[0058] Specifically, for example, the lock is in the power-off locked and power-on unlocked state, that is, after power is off, the non-circular groove is not aligned with the mating block 091. The mating groove is set to be aligned with the indicator hole 121 on the right. Therefore, when the state of the lock needs to be adjusted, first loosen the fastener, then rotate the adjusting member 06 so that the protrusion of the adjusting member 06 leaves the groove 022 where it is located, rotate the brake ring 02 to align the mating groove with the indicator hole 121 on the left, then adjust the protrusion of the adjusting member 06 to the other groove 022, and finally tighten the fastener.

[0059] In this embodiment, the state of the lock is easily adjusted by the cooperation between the indicating hole 121 and the cooperation groove of the state adjustment member 12 .

[0060] As an alternative, the matching groove on the head of the state adjustment member 12 can be set as a matching protrusion. Secondly, in the specific implementation, a screw can be used as the state adjustment member, and the screw can be passed through the bottom plate and fixed on the brake ring.

[0061] In a specific embodiment, as shown in Figure 5, each side plate 052 is provided with a groove, and the end of the brake ring 02 close to the bottom plate 051 is connected to a matching plate. The two sides of the matching plate are arc-shaped structures that match the two grooves. Semi-circular rings are provided on the matching plate and the bottom plate 051, and a number of balls 10 are provided in the circular ring formed by the two semi-circular rings.

[0062] As can be seen from the above, the connection between the base 05 and the brake ring 02 is a rotating connection. Specifically, a slot is provided on the side plate 052, and a matching plate is provided at one end of the brake ring 02 close to the bottom plate 051. The outer circumference of the matching plate is clamped in the slot, and the matching plate can rotate in the two slots. Therefore, the purpose of the brake ring 02 being able to rotate relative to the base 05 is achieved through the setting of the matching plate and the slot.

[0063] Again, semicircular rings are provided on the bottom plate 051 and the matching plate. The two semicircular rings form a circular ring. Several balls 10 are provided in the circular ring. The setting of the balls 10 reduces the friction force when the brake ring 02 rotates, making the rotation of the brake ring 02 smoother.

[0064] In a specific embodiment, each side plate 052 is connected to an extension plate 053 , and the slider 09 is located between the two extension plates 053 ; each extension plate 053 is provided with a clearance hole 0531 .

[0065] In this embodiment, the extension plate 053 is provided to limit the slider 09 between the two extension plates 053 , and the clearance hole 0531 of the extension plate 053 is used to allow the brake shaft 081 of the brake shaft assembly 08 to pass through the clearance hole 0531 of the side plate 052 and contact the slider 09 .

[0066] In a specific embodiment, as shown in Figures 3 and 4, brake shaft assemblies 08 cooperating with the lock buckle 11 are provided on both sides of the lock buckle 11, and the slider 09 is located between the two brake shaft assemblies 08. The part of the brake shaft of each brake shaft assembly close to the slider is a conical structure, and the side of the slider 09 close to each brake shaft is provided with a third inclined surface cooperating with the conical structure. When the two brake shaft assemblies 08 approach each other, the slider 09 generates a movement tendency close to the brake ring 02 through the conical structure and the third inclined surface.

[0067] Specifically, in this embodiment, both sides of the lock buckle 11 are provided with brake shaft assemblies 08 that cooperate with the lock buckle 11, so that both sides of the lock buckle 11 can contact the brake shaft assembly 08, solving the problem of twisting and deformation caused by the contact between one side of the lock buckle 11 and the brake shaft 081, thereby improving the service life of the lock; secondly, both sides of the lock buckle 11 are in contact with the brake shaft assembly 08, so the lock buckle 11 can withstand greater force, so that the lock can be used in places where it needs to withstand greater force.

[0068] Secondly, the slider 09 is located between the two brake shaft assemblies 08, and the slider 09 is provided with a third inclined surface that cooperates with the brake shaft assembly 08 on one side close to each brake shaft assembly 08. Therefore, when the lock buckle 11 is rotated, the lock buckle 11 generates a force on the brake shaft 081 of the brake shaft assembly 08, so that the brake shaft 081 has a tendency to move closer to each other. If the lock is in a state where it can be opened, the two brake shafts 081 can approach each other, thereby acting on the third inclined surface of the slider 09 through the makeshift hole 0531 on the extension plate 053, so that the slider 09 moves toward the direction close to the brake ring 02 to make way for the brake shaft 081, that is, the slider 09 is transformed from the state shown in Figure 3 to the state of Figure 4, thereby realizing the opening of the lock.

[0069] In a specific embodiment, a fixed block 023 is fixedly connected inside the brake ring 02, and the aforementioned non-circular groove is formed between the fixed block 023 and the ring wall of the brake ring 02. The fixed block 023 is provided with a first inclined surface 024 at both ends close to the non-circular groove. Along the direction close to the non-circular groove, the first inclined surface 024 is inclined in the direction away from the slider 09; the end of the mating block 091 close to the first inclined surface 024 is provided with a second inclined surface 0911 that cooperates with the first inclined surface 024.

[0070] In this embodiment, the non-circular groove is formed by fixing a fixing block 023 to the inner ring wall of the brake ring 02. In specific implementation, the fixing block 023 may be an arcuate block, a fan-shaped block, a semicircular block, or the like.

[0071] The cooperation of the first inclined-plane 024 and the second inclined-plane 0911 can make it easy to disengage the slider 09 from the first inclined-plane 024. That is, when the brake ring 02 rotates, the first inclined-plane 024 of the brake ring 02 slides on the second inclined-plane 0911 of the slider 09. When sliding to the matching block 091 and aligning with the non-circular groove, the matching block 091 can slide into the non-circular groove in a favorable manner. Secondly, it is more convenient to adjust the state of the lock. Specifically, the slider 09 is in the state where the matching block 091 leaves the non-circular groove under the effect of the slider return spring. When the lock is adjusted to the locked state, rotating the brake ring 02 makes the first inclined-plane 024 of the brake ring 02 slide on the second inclined-plane 0911 of the slider 09 so that the matching block 091 is no longer aligned with the non-circular groove.

[0072] In a specific embodiment, a return spring groove 025 is provided on one side of the brake ring 02 close to the slider 09 , one end of the slider return spring is located in the return spring groove 025 , and the other end of the slider return spring is connected to the slider 09 .
