Description

Technical Field

[0001] This invention belongs to the field of lock technology, and specifically relates to a lock. Background Technology

[0002] Locks are primarily used for installation on door frames, locking the door by having the latch on the door engage with the recess in the lock. A lock includes a lock body, a latch, a brake shaft, and control components. The latch is mounted on the main shaft and can rotate around it. The brake shaft works in conjunction with the latch to either allow the latch to rotate around the main shaft or prevent it from doing so. The brake shaft is limited by a slider; when the slider yields to the brake shaft, the latch can rotate around the main shaft. Whether the slider yields to the brake shaft depends on the positional relationship between the slider and the brake element. The control components drive the movement of the brake element, which in turn changes the positional relationship between the slider and the brake element.

[0003] Specifically, locks are classified into two types based on whether the latch can rotate around the main shaft after being powered on: power-on unlocking and power-off locking, and power-on locking and power-off unlocking. Power-on unlocking and power-off locking means that the latch can rotate and the lock can be opened after being powered on, but the latch cannot rotate and the lock cannot be opened after being powered off.

[0004] In existing technologies, such as Figure 1 As shown, the lock body is connected to a sleeve 01, which has several ball grooves containing spheres. The brake ring 02 (the aforementioned brake element) has several arc grooves on its ring wall. When the brake ring 02 is adjusted so that its arc grooves contact the spheres, the large diameter section of the moving bolt 03 can slide into the sleeve 01, and the slider can move towards the brake ring 02. When the brake ring 02 is adjusted so that its ring wall contacts the spheres, the large diameter section of the moving bolt 03 is blocked by the spheres, and the slider cannot move towards the brake ring 02. The existing technology has the disadvantage of inconvenient adjustment, and the presence of the spheres can easily cause jamming during adjustment. Summary of the Invention

[0005] In order to solve all or some of the above problems, the present invention aims to provide a lock with the advantage of convenient adjustment, which can achieve the state adjustment of the lock by rotating the brake ring to change the relative position of the mating block and the non-circular groove.

[0006] According to one aspect of the present invention, a lock is provided, comprising a lock body, a latch, a connecting rod, a slider, a slider return spring, a brake shaft assembly, and a control assembly, wherein the control assembly is used to control the movement of the connecting rod within the lock body, and the connecting rod is capable of returning to its original position after the force exerted by the control assembly is removed;

[0007] It also includes a base connected to the lock body, the base being connected to a brake ring, the brake ring having a non-circular groove, and the portion of the slider near the brake ring being a mating block that matches the non-circular groove; the connecting rod is engaged with the brake ring, and the movement of the connecting rod can drive the brake ring to rotate, and the rotation of the brake ring can change the relative position of the mating block and the non-circular groove.

[0008] Furthermore, an adjusting block is connected to the outer ring wall of the brake ring, the adjusting block is provided with a groove, and the connecting rod is connected to a protrusion that cooperates with the groove. The protrusion extends into the groove to drive the brake ring to rotate.

[0009] Furthermore, there are two grooves. When the protrusion is located in one of the grooves, the mating block can enter the non-circular groove; when the protrusion is located in the other groove, the mating block cannot enter the non-circular groove.

[0010] Furthermore, the connecting rod is connected to an adjusting member via two fasteners, the protrusion is provided on the adjusting member, one of the fasteners on the adjusting member is provided with an arc-shaped groove, the arc-shaped groove is centered on the pivot of the other fastener; each groove on the adjusting block is provided with a clearance groove for the protrusion to leave the groove.

[0011] Furthermore, the base includes a base plate and side plates located on both sides of the base plate. Each side plate is fixedly connected to the lock body, and the brake ring is rotatably connected to the base plate. The base plate is provided with two indicator holes, and the brake ring is connected to a state adjustment member. The head of the state adjustment member extending out of the base plate has a mating groove that mates with the indicator holes. When the mating groove is aligned with one of the indicator holes, the mating block can enter the non-circular groove; when the mating groove is aligned with the other indicator hole, the mating block cannot enter the non-circular groove.

[0012] Furthermore, each of the side plates is provided with a slot, and the end of the brake ring near the bottom plate is connected to a mating plate. The two sides of the mating plate are arc-shaped structures that mate with the two slots. Both the mating plate and the bottom plate are provided with semi-circular rings, and a number of spheres are provided in the ring formed by the two semi-circular rings.

[0013] Furthermore, each of the side plates is connected to an extension plate, and the slider is located between two of the extension plates; each of the extension plates is provided with a clearance hole.

[0014] Furthermore, a fixing block is fixedly connected inside the brake ring, and a non-circular groove is formed between the fixing block and the ring wall of the brake ring. The fixing block is provided with a first inclined surface at both ends near the non-circular groove. Along the direction near the non-circular groove, the first inclined surface is inclined in the direction away from the slider. The mating block is provided with a second inclined surface at one end near the first inclined surface, which mates with the first inclined surface.

[0015] Furthermore, both sides of the latch are provided with brake shaft assemblies that cooperate with the latch. The slider is located between the two brake shaft assemblies. The portion of the brake shaft of each brake shaft assembly near the slider is a tapered structure. The side of the slider near each brake shaft is provided with a third inclined surface that cooperates with the tapered structure. The two brake shaft assemblies approach each other, and the tapered structure and the third inclined surface cause the slider to move closer to the brake ring.

[0016] Furthermore, the brake ring has a return spring groove on the side near the slider, one end of the slider return spring is located in the return spring groove, and the other end of the slider return spring is connected to the slider.

[0019] The present invention can conveniently adjust the state of the lock by setting the mating block and the non-circular groove. Specifically, the state of the lock can be adjusted by rotating the brake ring to change the relative position of the mating block and the non-circular groove. Attached Figure Description

Detailed Implementation

[0031] To better understand the purpose, structure, and function of this invention, a lock according to this invention will be described in further detail below with reference to the accompanying drawings.

[0032] Locks are categorized into two types based on whether the latch can rotate around the main shaft after being powered on: power-on unlocking and power-off locking, and power-on locking and power-off unlocking. Taking unlocking after being powered on as an example, after power is off, the brake shaft blocks the latch's rotation direction, the slider blocks the brake shaft's movement direction, and the braking component (such as the brake ring) blocks the slider's movement direction. Therefore, the slider cannot move to allow the brake shaft to move, and the brake shaft cannot move to allow the latch to rotate. Thus, the latch cannot rotate, meaning the lock cannot be opened after power is off. After power is applied, the control component controls the brake ring to rotate. The rotation of the brake ring changes the relative position between the brake ring and the slider. At this time, the slider can move towards the brake ring to allow the brake shaft to move. The brake shaft can move, and the latch can rotate. Therefore, the lock can be opened after power is applied.

[0033] like Figure 2 , Figure 3 , Figure 4As shown, this invention illustrates a lock according to an embodiment of the present invention, including a lock body, a latch 11, a connecting rod 04, a slider 09, a slider return spring, a brake shaft assembly 08, and a control assembly. The latch 11 cooperates with the brake shaft assembly 08. When the latch 11 is subjected to the force of the latch tongue, it tends to rotate. Along the rotation direction of the latch 11 during unlocking, the brake shaft assembly 08 is located in front of the latch 11's direction of movement. Therefore, when the latch 11 is subjected to the force of the latch tongue and tends to rotate, the latch 11 exerts a corresponding force on the brake shaft assembly 08, causing the brake shaft assembly 08 to tend to move. Whether the brake shaft assembly 08 can move depends on the slider 09 and the brake ring 02. When the slider 09 can move towards the brake ring 02, that is, when the slider can make way for the movement of the brake shaft assembly, the brake shaft assembly 08 can move, and the latch can rotate.

[0034] As mentioned above, whether the brake shaft assembly 08 can move depends on the slider 09 and the brake ring 02. Specifically, the control component is used to control the movement of the connecting rod 04 in the lock body. The connecting rod 04 can reset after the force of the control component 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 towards the brake ring to not being able to move towards the brake ring, or from not being able to move towards the brake ring to being able to move towards the brake ring.

[0035] This embodiment also includes a base 05 connected to the lock body. The base 05 is connected to the brake ring 02. The brake ring 02 has a non-circular groove. The part of the slider 09 near the brake ring 02 is a mating block 091 that matches the non-circular groove. The rotation of the brake ring 02 can change the relative position of the mating block 091 and the non-circular groove.

[0036] Specifically, in this embodiment, as Figure 6 , Figure 7 , Figure 9 , Figure 10 As shown, the brake ring 02 has a non-circular groove. The part of the slider 09 near the brake ring 02 is a mating block 091 that matches the non-circular groove of the brake ring 02. Therefore, when the mating block 091 is aligned with the non-circular groove, the mating block 091 can enter the non-circular groove. At this time, under the action of the latch 11, the slider 09 can move towards the brake ring 02, so that the mating block 091 can enter the non-circular groove and the lock can be opened. When the mating block 091 is not aligned with the non-circular groove, under the action of the latch 11, the mating block 091 cannot enter the non-circular groove and the lock cannot be opened.

[0037] Furthermore, the linkage 04 and the brake ring 02 work together to move the linkage 04 and 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 change the relative position of the mating block 091 and the non-circular groove, thereby changing the state of the lock, such as changing from the unlocked state to the locked state, or from the locked state to the unlocked state.

[0038] The control component includes a solenoid and a movable spindle disposed inside the solenoid. The solenoid is used to generate a magnetic field, and the movable spindle is used to move under the action of the magnetic field to drive the connecting rod 04 to move. A connecting rod return spring 07 is provided between the connecting rod 04 and the lock body. The connecting rod return spring 07 is used to drive the connecting rod to return to its original position after the magnetic field disappears. The resetting of the connecting rod drives the brake ring to return to its original position.

[0039] Specifically, when the solenoid is energized, it generates a magnetic field. The moving spindle moves under the action of the magnetic field, pushing the connecting rod 04 to rotate, 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 button 07. The reset of the connecting rod 04 drives the brake ring 02 to rotate again, thereby realizing the reset of the brake ring 02.

[0040] Taking the case where the force of the control component disappears and the mating block 091 aligns with the non-circular groove as an example, the lock is in an openable state. When energized, the connecting rod 04 moves, causing the brake ring 02 to rotate. As the brake ring 02 rotates, the mating block 091 is no longer aligned with the non-circular groove, and the lock cannot be opened. In other words, the corresponding lock is energized locking and de-energized unlocking. Taking the case where the force of the control component disappears and the mating block 091 is not aligned with the non-circular groove as another example, the lock is in an inaccessible state. When energized, the connecting rod 04 moves, causing the brake ring 02 to rotate. As the brake ring 02 rotates, the relative position of the mating block 091 and the non-circular groove changes. When the connecting rod 04 moves to its limit position, the brake ring 02 stops rotating, and the mating block 091 aligns with the non-circular groove. At this point, the lock can be opened, and the corresponding lock is energized unlocking and de-energized locking.

[0041] The embodiments of the present invention change the state of the lock by adjusting the brake ring 02 to change the relative position of the mating block 091 and the non-circular groove, which has the advantage of convenient adjustment.

[0042] In one specific embodiment, such as Figure 7 , Figure 10 As shown, an adjusting block 021 is connected to the outer ring wall of the brake ring 02, and the adjusting block 021 is provided with a groove 022; 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.

[0043] In this embodiment, the connecting rod 04 drives the brake ring 02 to rotate through the cooperation of the groove 022 and the protrusion 061. Specifically, the adjusting block 021 is connected to the outer ring wall of the brake ring 02, and the adjusting block 021 is provided with a groove 022. The connecting rod 04 is connected to a protrusion 061, which extends into the groove 022. When the connecting rod 04 moves, it pushes the adjusting block 021 through the protrusion 061, thereby causing the adjusting block 021 and the brake ring 02 to rotate.

[0044] In one specific embodiment, there are two grooves 022. When the protrusion 061 is located in one of the grooves 022, the mating block 091 can enter the non-circular groove; when the protrusion 061 is located in the other groove 022, the mating block 091 cannot enter the non-circular groove.

[0045] This embodiment is provided with two adjustment grooves to facilitate adjustment of the lock's state, such as adjusting the lock to open when powered on or to open when powered off.

[0046] 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 case where the mating block can enter the non-circular groove when the connecting rod extends into one of the grooves as an example, the lock in this case is a power-off unlocking type. After power is applied, the connecting rod moves, causing 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 after power is applied. Correspondingly, the case where the mating block cannot enter the non-circular groove when the connecting rod extends into the other groove corresponds to a power-off locking and power-on unlocking type lock.

[0047] In this embodiment, by adjusting the position of the protrusion 061 within different grooves 022, the type of lock can be changed. Specifically, the lock can be adjusted from a power-off locking to a power-on unlocking to a power-off unlocking to a power-on locking, or vice versa.

[0048] In one specific embodiment, such as Figure 2 As shown, the connecting rod 04 is connected to the adjusting member 06 via two fasteners, as follows: Figure 11 As shown, a protrusion 061 is provided on the adjusting member 06. One of the fasteners on the adjusting member 06 is provided with an arc groove 062, with the arc groove 062 centered on the rotation axis of the other fastener. Each groove 022 on the adjusting block 021 is provided with a clearance groove for the protrusion 061 to leave the groove 022.

[0049] In this embodiment, the connecting rod 04 is connected to the adjusting member 06 by two fasteners, and the protrusion 061 is provided on the adjusting member 06. Therefore, the movement of the connecting rod 04 can drive the adjusting member 06 to move. The protrusion 061 on the adjusting member 06 extends into the groove 022, thereby pushing the brake ring 02 to rotate.

[0050] like Figure 11 As shown, one of the fasteners on the adjusting member 06 has an arc-shaped groove 062. This arc-shaped groove 062 is centered on the pivot of another fastener. Therefore, when it is necessary to move the protrusion 061 from one groove 022 to another groove 022, loosen the fastener and rotate the adjusting member 06 so that the adjusting member 06 moves away from the groove 022 through the clearance groove. Then, rotate the brake ring 02 and the adjusting member 06 so that the protrusion 061 of the adjusting member 06 can extend into another groove 022 through another clearance groove. Finally, tighten the fastener. As an alternative, three adjusting blocks 021 can be set, and a groove 022 is formed between two adjacent adjusting blocks 021. This setting does not require a separate clearance groove.

[0051] The state of the lock can be adjusted by setting the adjusting part 06, the arc groove 062 and the two grooves 022.

[0052] In one specific embodiment, such as Figure 6 As shown, the base 05 includes a base plate 051 and side plates 052 located on both sides of the base plate 051. Each side plate 052 is fixedly connected to the lock body, and the brake ring is rotatably connected to the base plate; as shown... Figure 8 As shown, the base plate 051 is provided with two indicator holes 121. The brake ring 02 is fixedly connected to a state adjustment member 12. The head of the state adjustment member 12 extending out of the base plate 051 has a mating groove that mates with the indicator holes 121. When the mating groove is aligned with one of the indicator holes 121, the mating block 091 can enter the non-circular groove; when the mating groove is aligned with the other indicator hole 121, the mating block 091 cannot enter the non-circular groove.

[0053] In this embodiment, the base 05 includes a base plate 051 and a side plate 052. The base 05 is fixed to the lock body through the side plate 052. The base plate 051 is provided with two indicator holes 121. The brake ring 02 is connected to a state adjustment component 12. The mating groove of the state adjustment component 12 and the indicator holes 121 cooperate to facilitate the adjustment of the lock state.

[0054] Specifically, for example, when the lock is in the power-off locked and power-on unlocked state, that is, when the power is off, the non-circular groove is not aligned with the mating block 091. At this time, the mating groove is set to be aligned with the indicator hole 121 on the right. Therefore, when it is necessary to adjust the state of the lock, 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 so that the mating groove is aligned with the indicator hole 121 on the left, then adjust the protrusion of the adjusting member 06 into another groove 022, and finally tighten the fastener.

[0055] In this embodiment, the matching groove between the indicator hole 121 and the state adjustment member 12 facilitates the adjustment of the lock's state.

[0056] As an alternative, the mating groove of the head of the state adjustment component 12 can be set as a mating protrusion. Alternatively, in specific implementation, a screw can be used as the state adjustment component, and the screw can be fixed to the brake ring by passing through the bottom plate.

[0057] In one specific embodiment, such as Figure 5 As shown, each side plate 052 is provided with a slot, and the brake ring 02 is connected to a mating plate at one end near the bottom plate 051. The two sides of the mating plate are arc-shaped structures that mate with the two slots. Both the mating plate and the bottom plate 051 are provided with semi-circular rings, and several spheres 10 are provided in the ring formed by the two semi-circular rings.

[0058] As mentioned above, the connection between the base 05 and the brake ring 02 is a rotatable connection. Specifically, the side plate 052 is provided with a slot, and the brake ring 02 is provided with a mating plate at one end near the base plate 051. The outer circumference of the mating plate is locked in the slot, and the mating plate can rotate in the two slots. Thus, the brake ring 02 can rotate relative to the base 05 through the setting of the mating plate and the slot.

[0059] Both the base plate 051 and the mating plate are provided with semi-circular rings. Two semi-circular rings form a circular ring. Several spheres 10 are provided inside the circular ring. The arrangement of the spheres 10 reduces the friction force when the brake ring 02 rotates, making the rotation of the brake ring 02 smoother.

[0060] In one specific embodiment, each side plate 052 is connected to an extension plate 053, and the slider 09 is located between two extension plates 053; each extension plate 053 is provided with a clearance hole 0531.

[0061] In this embodiment, the extension plate 053 is provided to limit the slider 09 between the two extension plates 053. 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.

[0062] In one specific embodiment, such as Figures 3-4 As shown, both sides of the latch 11 are provided with brake shaft assemblies 08 that cooperate with the latch 11. The slider 09 is located between the two brake shaft assemblies 08. The part of the brake shaft of each brake shaft assembly near the slider is a tapered structure. The side of the slider 09 near each brake shaft is provided with a third inclined surface that cooperates with the tapered structure. The two brake shaft assemblies 08 approach each other, and the tapered structure and the third inclined surface cause the slider 09 to move towards the brake ring 02.

[0063] Specifically, in this embodiment, both sides of the latch 11 are provided with brake shaft assemblies 08 that cooperate with the latch 11, so that both sides of the latch 11 can contact the brake shaft assembly 08, which solves the problem of twisting and deformation caused by one side of the latch 11 contacting the brake shaft 081, and improves the service life of the lock; secondly, since both sides of the latch 11 are in contact with the brake shaft assembly 08, the latch 11 can withstand greater force, so that the lock can be used in places where greater force is required.

[0064] Secondly, the slider 09 is located between the two brake shaft assemblies 08, and each side of the slider 09 near each brake shaft assembly 08 has a third inclined surface that mates with the brake shaft assembly 08. Therefore, when the latch 11 is rotated, the latch 11 exerts a force on the brake shaft 081 of the brake shaft assembly 08, causing the brake shafts 081 to tend to move closer to each other. If the lock is in the openable state, the two brake shafts 081 can move closer to each other, thereby acting on the third inclined surface of the slider 09 through the clearance hole 0531 on the extension plate 053, causing the slider 09 to move towards the brake ring 02 to make way for the brake shafts 081. That is, the slider 09 moves from... Figure 3 The state shown transforms into Figure 4 The lock is opened by adjusting the state of the lock.

[0065] In one specific embodiment, a fixing block 023 is fixedly connected inside the brake ring 02. The aforementioned non-circular groove is formed between the fixing block 023 and the ring wall of the brake ring 02. The fixing block 023 is provided with a first inclined surface 024 at both ends near the non-circular groove. Along the direction near the non-circular groove, the first inclined surface 024 is inclined away from the slider 09. The mating block 091 is provided with a second inclined surface 0911 at one end near the first inclined surface 024, which mates with the first inclined surface 024.

[0066] In this embodiment, the non-circular groove is formed by fixing block 023 fixedly connected to the inner ring wall of brake ring 02. In specific implementation, fixing block 023 can be an arc-shaped block, a fan-shaped block, or a semi-circular block, etc.

[0067] The engagement of the first inclined surface 024 and the second inclined surface 0911 facilitates the disengagement of the slider 09 from the first inclined surface 024. Specifically, when the brake ring 02 rotates, the first inclined surface 024 of the brake ring 02 slides on the second inclined surface 0911 of the slider 09. When the sliding reaches the alignment of the mating block 091 with the non-circular groove, the mating block 091 can slide into the non-circular groove. Furthermore, it makes adjusting the lock's state more convenient. Specifically, under the action of the slider return spring, the slider 09 is in a state where the mating block 091 is away from the non-circular groove. When it is necessary to adjust the lock to the locked state, rotating the brake ring 02 causes the first inclined surface 024 of the brake ring 02 to slide on the second inclined surface 0911 of the slider 09, preventing the mating block 091 from aligning with the non-circular groove.

[0068] In one specific embodiment, the brake ring 02 is provided with a reset spring groove 025 on the side near the slider 09, one end of the slider reset spring is located in the reset spring groove 025, and the other end of the slider reset spring is connected to the slider 09.
