[0002] As a commonly used device in daily production and life, locks have a very wide range of scenarios. A lock device is usually fastened by two lock buckles to achieve the locking of the lock device. However, the lock device in the prior art usually has only one lock buckle that can be moved to unlock the lock. However, once the movable lock buckle cannot be moved due to a malfunction, the entire lock device is in a state where it cannot be opened. Therefore, how to design a lock device with both lock buckles movable has become a problem that needs to be solved urgently. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model discloses a locking device.

[0004] A lock device, comprising a first component with a first fastener and a second component with a second fastener, wherein the second fastener can move in a direction away from the first fastener, and when the lock device is fastened, the first fastener and the second fastener are fastened to each other, and further comprising a mounting block, wherein the first fastener is movably mounted on the mounting block, and an unlocking device is also provided on the mounting block;

[0005] The unlocking device includes an unlocking push rod for pushing the first fastener to move, a limit block for limiting the position of the unlocking push rod, and an unlocking knob for adjusting the position of the limit block; the position of the limit block is adjusted by rotating the unlocking knob so that the unlocking push rod can move or drive the unlocking push rod to move, and the movement of the unlocking push rod pushes the first fastener to move in a direction away from the second fastener.

[0006] Specifically, under normal circumstances, the lock device can be opened by moving the second fastener to separate it from the first fastener. However, when the second component fails and the second fastener cannot be moved, the unlocking device can be used to move the position of the first fastener to separate the first fastener from the second fastener, so as to achieve the purpose of unlocking.

[0007] Turn the unlocking knob, the unlocking knob drives the limit block to move, the limit block drives the unlocking push rod to move, and the unlocking push rod pushes the first fastener to move in a direction away from the second fastener, thereby releasing the locking state of the first fastener and the second fastener.

[0008] Preferably, the first fastener includes a connecting rod and a locking tongue arranged at the end of the connecting rod, the middle part of the connecting rod is rotatably connected to the mounting block, the unlocking push rod is in contact with the connecting rod, and the contact point is close to the end of the connecting rod without the locking tongue.

[0009] Specifically, the first fastener is provided with one end of a locking tongue which is engaged with the second fastener, the middle part of the connecting rod is rotatably connected to the mounting block and the unlocking push rod is in contact with the connecting rod, and the contact point is close to the end of the connecting rod where the locking tongue is not provided. Therefore, when the unlocking push rod applies force to the connecting rod, due to the lever principle, the locking tongue will tilt in a direction away from the second fastener, and the first fastener and the second fastener are released from the locked state.

[0010] Preferably, the unlocking knob passes through the limit block and is movably connected to the mounting block, and the unlocking push rod passes through the limit block and is movably connected to the mounting block;

[0011] An adjusting block is provided on one side of the unlocking knob close to the mounting block, an adjusting hole adapted to the adjusting block is provided on the limiting block, and a limiting hole for the unlocking push rod to pass through is provided on the limiting block;

[0012] By turning the unlocking knob, the adjusting block applies pressure to the adjusting hole to drive the movement of the limit block. The size of the limit hole along the movement direction of the limit block is larger than the size of the unlocking push rod along the movement direction of the limit block; the size difference between the limit hole and the unlocking push rod along the movement direction of the limit block is smaller than the maximum movement displacement of the limit block.

[0013] Specifically, the relative position between the limit hole and the unlocking push rod can be adjusted by rotating the unlocking knob. Since the size difference between the limit hole and the unlocking push rod along the movement direction of the limit block is smaller than the maximum movement displacement of the limit block, there are three position relationships between the unlocking push rod and the limit hole: when there is interference between the unlocking push rod and the limit hole and the position of the unlocking push rod cannot be moved (the unlocking push rod and the inner wall of the limit hole are against each other, resulting in the unlocking push rod being unable to move in the direction of pushing the first fastener), the first fastener and the second fastener remain in a locked state; when there is no interference between the unlocking push rod and the limit hole and the position of the unlocking push rod can move freely, the first fastener and the second fastener remain in a locked state if the unlocking push rod is not moved, and the locked state of the first fastener and the second fastener can be released by moving the unlocking push rod; in addition, the inner wall of the limit hole (the inner wall opposite to the inner wall that makes the position of the unlocking push rod unable to move) can also move with the unlocking push rod so that the first fastener and the second fastener remain separated.

[0014] Preferably, an unlocking push block is provided at one end of the unlocking push rod away from the mounting block, and the size of the unlocking push block is larger than the size of the limiting hole.

[0015] Specifically, the structure of the unlocking push block can make the movement of the unlocking push rod more convenient and labor-saving.

[0016] Preferably, the adjustment block is a centrally symmetrical structure, and the adjustment block has at least two protrusions extending outwardly along the circumferential direction, and when the protrusions rotate in a direction away from the unlocking push rod, the limit block moves in a direction away from the unlocking push rod.

[0017] Specifically, the purpose of adjusting the position of the limit block by rotation can be achieved by setting the adjustment block to a centrally symmetrical structure with a protrusion.

[0018] Preferably, the mounting block is provided with a through slot, and a portion of the connecting rod is located in the through slot and movably connected to the inner wall of the through slot.

[0019] Specifically, under this structure, the connection between the mounting block and the first fastener is stable, and assembly and disassembly are convenient.

[0020] Preferably, the middle portion of the connecting rod is rotatably connected to the inner wall of the through slot via a rotating device, and the rotating device comprises a rotating shaft disposed apart from the connecting rod, and a connecting portion connecting the rotating shaft and the connecting rod;

[0021] It also includes a reset device, which includes an elastic device wrapped around the rotating shaft, one end of the elastic device abuts against the connecting rod, and the abutment position between the elastic device and the connecting rod is close to the end of the connecting rod where the locking tongue is not provided, and the elastic device and the unlocking push rod are respectively arranged on both sides of the connecting rod; the elastic device is a torsion spring.

[0022] Specifically, when the unlocking push rod is in a freely movable position, the unlocking push rod is moved to separate the first fastener from the second fastener. At this time, the torsion spring and the unlocking push rod are pressed against each other. When the force on the unlocking push rod stops, the unlocking push rod will automatically reset under the action of the torsion spring.

[0023] Preferably, the first component further comprises a panel, the panel is fixedly connected to the mounting block, and the panel is provided with a groove for accommodating the limiting block.

[0024] Specifically, the structure provided with the panel can provide good protection for the internal structure of the lock device, preventing external impurities from entering the interior of the lock device and affecting the performance.

[0025] Preferably, the unlocking knob further comprises a rotating block, the rotating block is sunken into the panel, and a special-shaped rotating groove is provided on the rotating block; the unlocking push rod protrudes from the panel.

[0026] Specifically, the structure of setting the special-shaped rotating groove can facilitate the rotation of the rotating block on the one hand, and on the other hand, the relative position between the unlocking push rod and the limiting hole can be determined by the orientation of the special-shaped rotating groove with different morphological characteristics in each direction.

[0027] Compared with the prior art, the utility model is beneficial in that:

[0028] The structure of the unlocking device allows the first fastener to be movable. Therefore, when the lock cannot be unlocked by moving the second fastener, the lock can be unlocked by first rotating the unlocking knob and then pushing the unlocking push rod to move the first fastener. The lock can also be unlocked by directly driving the unlocking push rod to move the first fastener. This structure solves the problem that the traditional lock cannot be unlocked unless the second fastener fails, and the process of unlocking with the unlocking device is convenient and quick, which makes the lock device provided by the utility model have good practicality.

[0035] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, the lock device includes a first component with a first fastener 11 and a second component with a second fastener 21, the second fastener 21 can move in a direction away from the first fastener 11, when the lock device is fastened, the first fastener 11 and the second fastener 21 are fastened to each other, and also includes a mounting block 30, the first fastener 11 is movably mounted on the mounting block 30, and the mounting block 30 is also provided with an unlocking device;

[0037] like Figure 5As shown, the unlocking device includes an unlocking push rod 41 for pushing the first fastener 11 to move, and a limit block 42 for limiting the position of the unlocking push rod 41, and also includes an unlocking knob for adjusting the position of the limit block 42; the position of the limit block 42 is adjusted by rotating the unlocking knob so that the unlocking push rod 41 can move or drive the unlocking push rod 41 to move, and the movement of the unlocking push rod 41 pushes the first fastener 11 to move in a direction away from the second fastener 21.

[0038] Normally, the lock device can be opened by moving the second fastener 21 away from the first fastener 11. However, when the second component fails and the second fastener 21 cannot be moved, the unlocking device can be used to move the first fastener 11 away from the second fastener 21 to achieve the purpose of unlocking.

[0039] By turning the unlocking knob, the unlocking knob drives the limit block 42 to move, and the limit block 42 drives the unlocking push rod 41 to move. The unlocking push rod 41 pushes the first fastener 11 to move in a direction away from the second fastener 21, thereby releasing the locking state of the first fastener 11 and the second fastener 21.

[0040] like Figure 6 As shown, the first fastener 11 includes a connecting rod 13 and a locking tongue 12 arranged at the end of the connecting rod 13. The middle part of the connecting rod 13 is rotatably connected to the mounting block 30. The unlocking push rod 41 contacts the connecting rod 13, and the contact point is close to the end of the connecting rod 13 where the locking tongue 12 is not arranged.

[0041] The first fastener 11 is provided with one end of a locking tongue 12 which is engaged with the second fastener 21, the middle part of the connecting rod 13 is rotatably connected to the mounting block 30 and the unlocking push rod 41 is in contact with the connecting rod 13, and the contact point is close to the end of the connecting rod 13 where the locking tongue 12 is not provided. Therefore, when the unlocking push rod 41 applies force to the connecting rod 13, due to the lever principle, the locking tongue 12 will tilt in a direction away from the second fastener 21, and the first fastener 11 and the second fastener 21 will be released from the locked state.

[0042] The unlocking knob passes through the limit block 42 and is movably connected to the mounting block 30 , and the unlocking push rod 41 passes through the limit block 42 and is movably connected to the mounting block 30 ;

[0043] An adjusting block 44 is provided on one side of the unlocking knob close to the mounting block 30, an adjusting hole 45 adapted to the adjusting block 44 is provided on the limiting block 42, and a limiting hole 46 for the unlocking push rod 41 to pass through is provided on the limiting block 42;

[0044] By turning the unlocking knob, the adjusting block 44 applies pressure to the adjusting hole 45 to drive the movement of the limit block 42. The size of the limit hole 46 along the movement direction of the limit block 42 is larger than the size of the unlocking push rod 41 along the movement direction of the limit block 42; the size difference between the limit hole 46 and the unlocking push rod 41 along the movement direction of the limit block 42 is smaller than the maximum movement displacement of the limit block 42.

[0045] By rotating the unlocking knob, the relative position between the limit hole 46 and the unlocking push rod 41 can be adjusted. Since the size difference between the limit hole 46 and the unlocking push rod 41 along the movement direction of the limit block 42 is smaller than the maximum movement displacement of the limit block 42, there are three positional relationships between the unlocking push rod 41 and the limit hole 46: Figure 2 As shown, when there is interference between the unlocking push rod 41 and the limiting hole 46 and the position of the unlocking push rod 41 cannot be moved (the unlocking push rod 41 abuts against the inner wall of the limiting hole 46, causing the unlocking push rod 41 to be unable to move in the direction of pushing the first fastener 11), the first fastener 11 and the second fastener 21 remain in a locked state; Figure 3 As shown, when there is no interference between the unlocking push rod 41 and the limiting hole 46, and the position of the unlocking push rod 41 can be freely moved, the first fastener 11 and the second fastener 21 remain locked without moving the unlocking push rod 41, and the locking state of the first fastener 11 and the second fastener 21 can be released by moving the unlocking push rod 41; Figure 4 As shown, in addition, the inner wall of the limiting hole 46 (the inner wall opposite to the inner wall that prevents the unlocking push rod 41 from moving) can also move with the unlocking push rod 41 so that the first fastener 11 and the second fastener 21 remain separated.

[0046] An unlocking push block 47 is disposed at one end of the unlocking push rod 41 away from the mounting block 30 , and the size of the unlocking push block 47 is larger than the size of the limiting hole 46 .

[0047] The structure of the unlocking push block 47 can make the movement of the unlocking push rod 41 more convenient and labor-saving.

[0048] The adjusting block 44 is a centrally symmetrical structure, and at least two protrusions 51 extend outwardly along the circumferential direction of the adjusting block 44 . When the protrusions 51 rotate in a direction away from the unlocking push rod 41 , the limiting block 42 moves in a direction away from the unlocking push rod 41 .

[0049] The purpose of adjusting the position of the limit block 42 by rotating can be achieved by setting the adjustment block 44 to a centrally symmetrical structure with the protrusion 51 .

[0050] The mounting block 30 is provided with a through slot 31 , and a portion of the connecting rod 13 is located in the through slot 31 and movably connected to the inner wall of the through slot 31 .

[0051] In this structure, the connection between the mounting block 30 and the first fastener 11 is stable and easy to assemble and disassemble.

[0052] The middle part of the connecting rod 13 is rotatably connected to the inner wall of the through slot 31 through a rotating device, and the rotating device includes a rotating shaft 14 separated from the connecting rod 13 and a connecting part connecting the rotating shaft 14 and the connecting rod 13;

[0053] It also includes a reset device, which includes an elastic device 52 wrapped around the rotating shaft 14, one end of the elastic device 52 abuts against the connecting rod 13, and the abutment position of the elastic device 52 and the connecting rod 13 is close to the end of the connecting rod 13 where the lock tongue 12 is not provided, and the elastic device 52 and the unlocking push rod 41 are respectively arranged on both sides of the connecting rod 13; the elastic device 52 is a torsion spring.

[0054] When the unlocking push rod 41 is in a freely movable state, the unlocking push rod 41 is moved to separate the first fastener 11 from the second fastener 21. At this time, the torsion spring and the unlocking push rod 41 are pressed against each other. When the force on the unlocking push rod 41 stops, the unlocking push rod 41 will automatically reset under the action of the torsion spring.

[0055] The first component further includes a panel 60 , which is fixedly connected to the mounting block 30 . The panel 60 is provided with a groove 61 for accommodating the limiting block 42 .

[0056] The structure of the panel 60 can well protect the internal structure of the lock device and prevent external impurities from entering the interior of the lock device and affecting the performance; in addition, the structure of the groove 61 can also well stabilize the position of the limit block 42.

[0057] The unlocking knob further includes a rotating block 71 , which is sunken into the panel 60 and has a special-shaped rotating groove 72 ; the unlocking push rod 41 protrudes from the panel 60 .

[0058] The structure of providing the special-shaped rotating groove 72 can facilitate the rotation of the rotating block 71 on the one hand, and on the other hand, the relative position between the unlocking push rod 41 and the limiting hole 46 can be determined by the orientation of the special-shaped rotating groove 72 with different morphological characteristics in each direction.
