Description

Technical Field

[0001] This invention relates to the field of door lock technology, and in particular to a deadbolt structure and a door lock. Background Technology

[0002] In door and window hardware, the deadbolt mechanism of door locks is mainly divided into two types:

[0003] 1. Includes locking components, driving components that drive the locking components, housing, and rotating wheel; when it is necessary to lock or unlock the door lock, the lock cylinder or simple lock cylinder drives the driving components to rotate and swing, and the driving components then drive the locking components to directly or indirectly lock the rotating wheel, restricting the rotation of the rotating wheel (releasing the rotating wheel when unlocking), thereby achieving the function of locking or unlocking.

[0004] 2. Includes locking components, housing, rotating wheel, and transmission components that move in conjunction with the rotating wheel; when it is necessary to lock or unlock the door lock, the locking components are moved by the lock cylinder or simple lock cylinder, and the locking components lock the transmission components that are connected to the rotating wheel, thereby indirectly restricting the rotation of the rotating wheel (releasing the rotating wheel when unlocking), thus achieving the function of locking or unlocking;

[0005] Both of the above solutions require necessary structures such as locking components and driving or transmission components to be realized, resulting in complex structures, inconvenient assembly, and high costs. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a deadbolt structure and door lock.

[0012] In one specific embodiment, the notch is arc-shaped.

[0013] In one specific embodiment, the deadbolt is a flat strip, and the protrusion is located in the middle section of the deadbolt.

[0014] In one specific embodiment, the longitudinal cross-section of the protrusion is M-shaped.

[0015] In one specific embodiment, the first notch and the second notch have the same structure, and the first notch is U-shaped.

[0016] In one specific embodiment, the locking structure further includes a locking tongue assembly and a spring; the locking tongue assembly is movably connected to the second housing, and one end of the rotating wheel is throttle-connected to the locking tongue assembly and the other end abuts against the spring.

[0017] The advantages of the deadbolt structure of the present invention compared with the prior art are: by simultaneously locking the first notch, the notch groove and the second notch by the deadbolt component, deadbolt is achieved, which simplifies the deadbolt structure of conventional door locks, reduces product costs and improves product assembly efficiency.

[0046] See Figures 1 to 16 As shown, the present invention discloses a specific embodiment of a deadbolt structure applied to a lock box, specifically including a first housing 10, a second housing 20, a rotating wheel 30, and a deadbolt member 40; the first housing 10 is provided with a first through hole 11, and the edge of the first through hole 11 is provided with a first notch 12; the second housing 20 is provided with a second through hole 21, and the edge of the second through hole 21 is provided with a second notch 22; the rotating wheel 30 is located between the first through hole 11 and the second through hole 21, and the rotating wheel 30 is rotatably connected to the first through hole 11 and the second through hole 21; the edge of the rotating wheel 30 is provided with a notch groove 31; when the deadbolt member 40 simultaneously engages the first notch 12, the notch groove 31, and the second notch 22, deadbolt is achieved.

[0047] Specifically, the deadbolt 40 simultaneously engages the first notch 12, the notch groove 31, and the second notch 22 to achieve deadbolt locking, which simplifies the deadbolt structure of conventional door locks, reduces product costs, and improves product assembly efficiency.

[0048] In one embodiment, the rotating wheel 30 is further provided with a polygonal through hole 32.

[0049] Specifically, the polygonal through hole 32 is used to connect to the drive shaft of the door handle, so that when the door handle is turned, the rotating wheel 30 can be driven to rotate.

[0050] Example 1, see Figures 1 to 7 As shown:

[0051] In one embodiment, the anti-locking member 40 is provided with a protrusion 41, which is used to lock the first notch 12, the notch groove 31 and the second notch 22.

[0052] Specifically, in use, the anti-locking member 40 passes through the notch 31 and penetrates the first through hole 11 and the second through hole 21. In the unlocked state, the protrusion 41 is located between the first housing 10 and the second housing 20 or outside the first housing 10 and the second housing 20. At this time, the rotation diameter of the anti-locking member 40 at the thickness plane position of the first housing 10 and the second housing 20 is smaller than the diameter of the first through hole 11 and the second through hole 21. At this time, rotating the wheel 30 can drive the anti-locking member 40 to rotate together. The first side wing 33 of the wheel 30 is connected to the drive arm 521 of the latch assembly 50, which drives the latch 51 to retract into the second housing 20 along the channel hole 23. After the force of rotating the wheel 30 is released, the wheel 30 is reset to the initial position under the action of the spring 60.

[0053] In one embodiment, the deadbolt structure further includes a latch assembly 50 and a spring 60; the latch assembly 50 is movably connected to the second housing 20, and one end of the rotating wheel 30 is connected to the latch assembly 50 in a transmission manner, while the other end abuts against the spring 60.

[0054] Specifically, when the rotating wheel 30 is rotated, the rotating wheel 30 drives the locking tongue assembly 50 to move. At this time, the spring 60 is compressed. When the force of rotating the rotating wheel 30 is released, the rotating wheel 30 returns to its initial position under the elastic force of the spring 60.

[0055] In one embodiment, the latch assembly 50 includes a latch 51 and a latch body 52. ​​The second housing 20 is provided with a channel hole 23 corresponding to the latch 51. The latch body 52 is provided with a drive arm 521. One end of the rotating wheel 30 is provided with a first side wing 33 and the other end is provided with a second side wing 34. The first side wing 33 is connected to the drive arm 521 in a transmission manner, and the second side wing 34 abuts against the spring 60.

[0056] Specifically, when the rotating wheel 30 is rotated, the first side wing 33 drives the drive arm 521 to move, causing the locking tongue 51 to retract into the second housing 20 along the channel hole 23. At this time, the spring 60 is compressed. When the force of rotating the wheel 30 is released, the second side wing 34 moves under the elastic force of the spring 60, driving the rotating wheel 30 to return to the initial position.

[0057] In one embodiment, a limiting protrusion 341 is provided on the second side wing 34, and one end of the spring 60 is sleeved on the limiting protrusion 341, so that when the spring 60 is compressed or extended, its movement direction is always in a straight line, so that the elastic force of the spring 60 remains stable, and the movement stroke of the second side wing 34 is consistent.

[0058] In one embodiment, the second housing 20 is further provided with a support block 24, one end of the spring 60 abuts against the support block 24 and the other end abuts against the second side wing 34.

[0059] Specifically, a cavity for placing the spring 60 is formed between the support block 24 and the second housing 20. One end of the spring 60 abuts against the support block 24 and the other end abuts against the second side wing 34, so that when the spring 60 is compressed or extended, its movement direction is always in a straight line, ensuring the stability of the elastic force of the spring 60.

[0060] In one embodiment, the support block 24 is also provided with a protrusion for limiting the spring 60, which can effectively prevent the spring 60 from shifting.

[0061] In one embodiment, a limiting plate 511 is provided on the side of the locking tongue 51 near the support block 24. When the locking tongue 51 retracts into the second housing 20, the limiting plate 511 abuts against the support block 24, thereby limiting the position.

[0062] In one embodiment, the second housing 20 is further provided with connecting posts 25. One connecting post 25 is located on the side of the second side wing 34 away from the spring 60. When the wheel 30 is in the initial position, the second side wing 34 abuts against the connecting post 25, which serves as a limit to prevent the second side wing 34 from disengaging from the spring 60. Another connecting post 25 is located on the side of the drive arm 521 away from the latch 51. When the latch 51 retracts into the second housing 20, the drive arm 521 abuts against the connecting post 25, which also serves as a limit. The first housing 10 is connected to the connecting post 25 by screws to achieve the connection between the first housing 10 and the second housing 20.

[0063] In one embodiment, the latch 51 and the latch body 52 are integrally formed, which has high strength and only requires one set of molds for production, thus reducing production costs.

[0064] In one embodiment, the rotor 30, the first side wing 33 and the second side wing 34 are integrally formed structures, which have high strength and only require one set of molds for production, thus reducing production costs.

[0065] In one embodiment, both the outer sides of the first through hole 11 and the second through hole 21 are provided with grooves, and the rotating wheel 30 is rotatably connected to the grooves, resulting in a compact structure and strong sealing performance.

[0066] In one embodiment, the deadbolt 40 is a deadbolt bar.

[0067] Specifically, the deadbolt 40 is a flat strip, and the protrusion 41 is located in the middle section of the deadbolt 40.

[0068] In one embodiment, the longitudinal cross-section of the protrusion 41 is M-shaped.

[0069] Specifically, the M-shaped protrusion 41 has high strength and good locking effect.

[0070] In one embodiment, the first notch 12 and the second notch 22 have the same structure, and the first notch 12 is U-shaped.

[0071] Specifically, the U-shaped notch facilitates the up-and-down movement of the protrusion 41, and when the protrusion 41 is locked in the notch, the U-shaped notch is subjected to uniform force, resulting in a more stable locking effect.

[0072] Preferably, the notch 31 is also U-shaped to correspond to the shape of the anti-locking member 40.

[0073] Specifically, when it is necessary to lock the door, the position of the deadbolt bar is moved (either along the length direction or perpendicular to the length direction) so that the protrusion 41 of the deadbolt bar simultaneously locks the first notch 12, the notch groove 31 and the second notch 22, so that the rotating wheel 30 cannot rotate, thereby realizing the deadbolt operation.

[0074] Example 2, see Figures 8 to 10 As shown:

[0075] In one embodiment, the anti-locking member 40 is rotatably configured, and the anti-locking member 40 is provided with a first recess 42 and a second recess 43. When the first recess 42 and the second recess 43 are opposite to the first notch 12 and the second notch 22, the anti-locking is achieved.

[0076] Specifically, the locking mechanism of the anti-locking member 40 is changed from movement to rotation. The anti-locking member 40 has a recess at the position corresponding to the notch of the first housing 10 and the second housing 20. In the unlocked state, the recess of the anti-locking member 40 faces the notch of the housing. At this time, the rotating wheel 30 can be rotated. After the anti-locking member 40 rotates 180 degrees, the recess of the anti-locking member 40 faces away from the notch of the housing. At this time, the anti-locking member 40 is stuck in the notch of the housing, thus achieving anti-locking.

[0077] In one embodiment, the deadbolt 40 is cylindrical, and the first recess 42 and the second recess 43 are located in the middle section of the deadbolt 40.

[0078] Specifically, the first recess 42 and the second recess 43 are located in the middle section of the anti-locking member 40, which facilitates manual rotation of the anti-locking member 40.

[0079] In one embodiment, the notch 31 is arc-shaped to correspond to the shape of the anti-locking member 40, so that the anti-locking member 40 can rotate within the notch 31.

[0080] Specifically, the only structural difference between the rotating wheel 30 in Embodiment 2 and the rotating wheel 30 in Embodiment 1 is the shape of the notch groove 31.

[0081] Example 3, see Figures 11 to 16 As shown:

[0082] In one embodiment, the locking structure is applied to the transmission assembly, which further includes a transmission member 70. The transmission member 70 is slidably connected to the first housing 10 and the second housing 20, and is drively connected to the rotating wheel 30.

[0083] Specifically, when the rotating wheel 30 is rotated, the rotating wheel 30 drives the transmission component 70 to move along the first housing 10 and the second housing 20.

[0084] In one embodiment, the end of the rotating wheel 30 near the transmission member 70 is provided with a driving part 35, and the transmission member 70 is provided with a groove 71 corresponding to the driving part 35, and the driving part 35 is slidably connected to the groove 71.

[0085] Specifically, the upper and lower ends of the drive unit 35 are provided with drive protrusions 351, which are slidably connected to the slide groove 71. When the rotating wheel 30 is rotated, the drive protrusions 351 slide in the slide groove 71 and drive the transmission component 70 to move.

[0086] In one embodiment, the first housing 10 and the second housing 20 are further provided with an extended protrusion 26 at one end near the transmission member 70. The transmission member 70 is slidably connected to the inner side of the extended protrusion 26 at the upper and lower ends, resulting in a compact structure.

[0087] In one embodiment, the locking structure further includes a cover plate 80, which is connected to the first housing 10 and the second housing 20.

[0088] Specifically, the cover plate 80 is connected to the outside of the extended protrusions 26 at the upper and lower ends to limit the sliding of the transmission member 70 in a specified direction.

[0089] Specifically, the deadbolt 40 is strip-shaped or columnar, passing through the notch 31 and penetrating the first through hole 11 and the second through hole 21. When the door lock is not deadbolted, the deadbolt 40 is only in the notch 31 of the wheel 30 and can rotate with the wheel 30. When it is necessary to deadbolt the door lock, the deadbolt 40 is moved to the outside of the wheel 30, so that the deadbolt 40 is simultaneously in the first notch 12, the notch 31 and the second notch 22. At this time, the wheel 30 is restricted from rotating, thereby realizing the deadbolt function.

[0090] The present invention also discloses a door lock, including the deadbolt structure as described above.

[0091] Specifically, the deadbolt 40 simultaneously engages the first notch 12, the notch groove 31, and the second notch 22 to achieve deadbolt locking, which simplifies the conventional door lock structure, reduces product costs, and improves product assembly efficiency.

[0092] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
