Description

Technical Field

[0001] This application belongs to the field of lock technology, specifically relating to a deadbolt mechanism and lock. Background Technology

[0002] A lock typically includes a base and a handle mounted on the base. The handle is equipped with a deadbolt mechanism. Rotating the deadbolt mechanism rotates the deadbolt lever to control the extension or retraction of the deadbolt, thereby locking or unlocking the lock.

[0003] In related technologies, because the gap between the handle and the door frame is small, to prevent users from pinching their fingers when opening and closing the door, the user can adjust the installation position of the handle according to the door's opening direction to increase the gap between the handle and the door frame. However, after adjusting the handle's installation position, since the position of the deadbolt lever remains unchanged, the position of the deadbolt operating component also remains unchanged. This results in the deadbolt operating component not moving synchronously with the handle, and the gap between the deadbolt operating component and the door frame remains small, making it inconvenient for the user to grip and operate the deadbolt operating component.

[0004] Therefore, the related technology has the defect that the locking mechanism cannot move synchronously with the handle. Utility Model Content

[0005] The purpose of this application is to provide a deadbolt mechanism and lock that can solve the problem in related technologies that the deadbolt operating component cannot move synchronously with the handle.

[0006] In a first aspect, embodiments of this application provide a locking mechanism, including:

[0007] The deadbolt is used for driving the deadbolt of the lock.

[0008] A deadbolt connector is connected to the deadbolt actuating member, and the deadbolt connector is rotatably mounted on the base of the lock.

[0009] A deadbolt mechanism is rotatably mounted on the handle of the lock.

[0010] A movable component for being movably mounted on the handle;

[0011] The locking mechanism can switch between at least two positions as the handle is offset. The locking mechanism is driven to the moving component at each of the positions. The moving component is driven to the locking connector. The locking mechanism can drive the moving component to move, thereby causing the locking connector to rotate.

[0012] Secondly, this application also provides a lock, including a base, a handle, a deadbolt, and the aforementioned deadbolt mechanism. The handle is connected to the base, the deadbolt actuating member of the deadbolt mechanism is throttle-connected to the deadbolt, the deadbolt connecting member of the deadbolt mechanism is rotatably disposed on the base, the deadbolt operating member is rotatably disposed on the handle, and the moving component is slidably disposed on the handle.

[0013] In this embodiment, the movable component is movably mounted on the handle and is connected to the deadbolt operating component and the deadbolt connecting component respectively. Rotating the deadbolt operating component can drive the movable component to move, and the movement of the movable component can drive the deadbolt connecting component to rotate, thereby driving the deadbolt to rotate, thereby driving the deadbolt tongue to extend or retract, so as to realize deadbolt or unlock.

[0014] Because the deadbolt is connected to the moving component at at least two locations in the handle's offset direction, it means that the deadbolt can drive the deadbolt toggle to rotate at different locations in the handle's movement direction. This allows the user to adjust the installation position of the deadbolt as needed, increasing the gap between the deadbolt and the door frame, thus facilitating the user's grip and operation of the deadbolt. Simultaneously, it allows the deadbolt to move synchronously with the handle, helping to keep the deadbolt in a centered position on the handle. Attached Figure Description

[0043] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0044] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0045] The locking mechanism and lock provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0046] refer to Figures 1-18 The deadbolt mechanism 300 provided in this application embodiment may include a deadbolt toggle 360, a deadbolt connector 320, a deadbolt operation member 310, and a moving component 330.

[0047] The deadbolt 360 can be used to drive the deadbolt of the lock, and the deadbolt connector 320 can be connected to the deadbolt 360. The deadbolt connector 320 is rotatably mounted on the base 100 of the lock. The deadbolt operation 310 can be rotatably mounted on the handle 200 of the lock. By rotating the deadbolt operation 310, the deadbolt 360 can be driven to rotate, thereby driving the deadbolt to extend or retract, so as to realize the deadbolt and the deadbolt unlocking.

[0048] The movable component 330 is movably mounted on the handle 200, and the deadbolt operation member 310 can switch between at least two positions as the handle 200 is offset. The deadbolt operation member 310 is throttle-connected to the movable component 330 in each position. The movable component 330 is throttle-connected to the deadbolt connector 320, and the deadbolt operation member 310 can drive the movable component 330 to move, thereby causing the deadbolt connector 320 to rotate. Because the deadbolt operation member 310 is throttle-connected to the movable component 330, when the deadbolt operation member 310 is rotated, it drives the movable component 330 to move. Since the movable component 330 is throttle-connected to the deadbolt connector 320, the movement of the deadbolt movable component 330 can cause the deadbolt connector 320 to rotate, thereby causing the deadbolt actuator 360 to rotate, which can then drive the deadbolt tongue to extend or retract.

[0049] With this configuration, since the deadbolt 310 is connected to the moving component 330 at at least two positions in the offset direction of the handle 200, it means that the deadbolt 310 can drive the deadbolt 360 to rotate at different positions in the moving direction of the handle 200. This allows the user to adjust the installation position of the deadbolt 310 as needed to increase the gap between the deadbolt 310 and the door frame 400, thus facilitating the user's grip and operation of the deadbolt 310. Simultaneously, it allows the deadbolt 310 to move synchronously with the handle 200, thereby helping to keep the deadbolt 310 in a centered position on the handle 200.

[0050] In an optional embodiment of this application, the deadbolt operating member 310 is connected to the moving component 330 via a first gear 340, and the deadbolt connecting member 320 is connected to the moving component 330 via a second gear 350. This configuration improves the transmission stability and efficiency between the deadbolt operating member 310, the moving component 330, and the deadbolt connecting member 320.

[0051] Here, the first gear 340 can be coaxially connected to the deadbolt operating member 310, and the second gear 350 can be coaxially connected to the deadbolt connecting member 320. The second gear 350 can be disposed at the end of the deadbolt connecting member 320 opposite to the deadbolt actuating member 360, and the second gear 350 can be connected to the deadbolt connecting member 320 as an integral structure.

[0052] Optionally, the first gear 340 is provided with a protrusion 341, at least a portion of which can be embedded in the deadbolt 310 to achieve connection between the deadbolt 310 and the first gear 340. Further optionally, to improve the connection strength between the first gear 340 and the deadbolt 310, the first gear 340 can be provided with a fixing hole 342, through which a fixing screw 380 can pass to connect with the deadbolt 310 to fix the first gear 340 and the deadbolt 310.

[0053] In other embodiments, the deadbolt 310 can contact the movable component 330, and the deadbolt connector 320 can contact the movable component 330. Rotating the deadbolt 310 causes the movable component 330 to move due to friction between the deadbolt 310 and the movable component 330, and the deadbolt connector 320 causes the deadbolt connector 320 to rotate due to friction between the movable component 330 and the deadbolt connector 320. Alternatively, the locking operation member 310 can be connected to the moving component 330 via a first transmission wheel, and the locking connector 320 can be connected to the moving component 330 via a second transmission wheel. The first transmission wheel and the locking operation member 310 can be coaxially connected, and the second transmission wheel can be coaxially connected to the locking connector 320. The first transmission wheel can contact the moving component 330, and the second transmission wheel can contact the moving component 330. The first transmission wheel can drive the moving component 330 to move through the friction between the first transmission wheel and the moving component 330, and the moving component 330 can be driven to move through the friction between the moving component 330 and the second transmission wheel.

[0054] In one optional embodiment of this application, the moving component 330 may include a first connecting rack 331 and a second connecting rack 332, wherein the first connecting rack 331 may mesh with a first gear 340 and the second connecting rack 332 may mesh with a second gear 350.

[0055] The length direction of the first connecting rack 331 and the length direction of the second connecting rack 332 can both be parallel to the offset direction of the handle 200. Furthermore, the first connecting rack 331 and the second connecting rack 332 are distributed in a direction perpendicular to the offset direction of the handle 200, and the first connecting rack 331 and the second connecting rack 332 are connected by a fastener 333.

[0056] With this configuration, rotating the anti-locking operating member 310 can drive the first connecting rack 331 to move, the first connecting rack 331 can drive the second connecting rack 332 to move, the second connecting rack 332 can drive the second gear 350 to rotate, and thus drive the anti-locking connector 320 to rotate. At the same time, since the first connecting rack 331 and the second connecting rack 332 are distributed in a direction perpendicular to the offset direction of the handle 200, it is beneficial to reduce the space occupied by the moving component 330 in the offset direction of the handle 200, and thus it is beneficial to reduce the width of the handle 200.

[0057] In addition, the method of using the first connecting rack 331 and the second connecting rack 332 to drive the first gear 340 and the second gear 350 respectively has higher transmission accuracy and can achieve precise motion control compared to the method of using the first chain and the second chain to drive the first gear 340 and the second gear 350 respectively. Furthermore, the rack has high rigidity and can maintain stable transmission performance under high load, resulting in more stable transmission.

[0058] In other embodiments, the moving component 330 may also include a first chain and a second chain, a first gear 340 meshing with the first chain, and a second gear 350 meshing with the second chain. The length directions of both the first chain and the second chain may be parallel to the offset direction of the handle 200, and the first chain and the second chain are distributed in a direction perpendicular to the offset direction of the handle 200. The first chain and the second chain may be mounted on a fixing member 333, and the fixing member 333 is slidably connected to the handle 200.

[0059] In an optional embodiment, the protruding direction of the teeth of the first connecting rack 331 is the same as that of the teeth of the second connecting rack 332. This arrangement allows the rotation directions of the first gear 340 and the second gear 350 to be aligned, thereby ensuring that the rotation direction of the deadbolt 360 is the same as that of the deadbolt operating member 310. Compared to the arrangement described below where the protruding directions of the teeth of the first connecting rack 331 and the teeth of the second connecting rack 332 are opposite, this arrangement more easily adapts to the driving logic of the deadbolt tongue, thus eliminating the need to change the installation direction of the deadbolt operating member 310.

[0060] Of course, the protruding direction of the teeth of the first connecting rack 331 and the protruding direction of the teeth of the second connecting rack 332 can also be opposite.

[0061] In an optional embodiment, the first connecting rack 331 and the second connecting rack 332 can be located on the same plane. This allows the first gear 340 and the second gear 350 to be located on the same plane, thereby reducing the thickness of the handle 200. The fixing member 333 can be connected to the side of the first connecting rack 331 opposite to the anti-locking actuator 360 and the side of the second connecting rack 332 opposite to the anti-locking actuator 360, respectively. With this configuration, the fixing member 333 can avoid the first gear 340 and the second gear 350, thus avoiding interference with the installation and rotation of the first gear 340 and the second gear 350, and also maximizing the movement space of the moving component 330.

[0062] Of course, the first connecting rack 331 and the second connecting rack 332 may not be located on the same plane. Specifically, the first connecting rack 331 and the second connecting rack 332 may be spaced apart in the thickness direction of the handle 200. Alternatively, the first connecting rack 331, the second connecting rack 332 and the fixing member 333 may all be located on the same plane.

[0063] Optionally, the fixing member 333 may include a first fixing rod 3331 and a second fixing rod 3332. The two ends of the first fixing rod 3331 can be connected to the first connecting rack 331 and the second connecting rack 332, respectively. The two ends of the second fixing rod 3332 can also be connected to the first connecting rack 331 and the second connecting rack 332, respectively. Furthermore, the first fixing rod 3331 and the second fixing rod 3332 can be positioned close to the two ends of the first connecting rack 331. This arrangement improves the connection strength between the first connecting rack 331 and the second connecting rack 332, and also helps ensure a balance of forces on the first connecting rack 331 and the second connecting rack 332.

[0064] Optionally, the number of teeth and module of the first connecting rack 331 are the same as those of the second gear 350, and the number of teeth and module of the first gear 340 are also the same as those of the second gear 350. This ensures the matching of the moving component 330 with the first gear 340 and the second gear 350 respectively, thereby improving the stability of the transmission.

[0065] In another optional embodiment of this application, the moving component 330 may include a first connecting rack 331, with both the first gear 340 and the second gear 350 meshing with it. Furthermore, the length direction of the first connecting rack 331 may be parallel to the offset direction of the handle 200. This arrangement helps reduce the space occupied by the moving component 330 in the direction perpendicular to the offset direction of the handle 200. Moreover, compared to using a first chain to connect the first gear 340 and the second gear 350, the method of connecting the first connecting rack 331 with the first gear 340 and the second gear 350 provides higher transmission accuracy and enables precise motion control. Additionally, the rack has high rigidity, maintaining stable transmission performance under high loads, resulting in more stable transmission.

[0066] Of course, the moving component 330 may also include a first chain, and the first gear 340 and the second gear 350 may both be connected to the first chain. The length direction of the first chain may be parallel to the offset direction of the handle 200.

[0067] In an optional embodiment of this application, the deadbolt connector 320 may be provided with a first mounting groove 321 and a second mounting groove 322, and the first mounting groove 321 and the second mounting groove 322 may be intersected.

[0068] The aforementioned at least two positions may include a first position, a second position, and a third position. The first position may be used to be opposite to the middle position of the base 100 in the offset direction of the handle 200. The second and third positions may be located on both sides of the first position, respectively.

[0069] When the deadbolt 310 is in the first position, part of the deadbolt 360 can be embedded in the first mounting groove 321, that is, the deadbolt connector 320 can be connected to the deadbolt 360 through the first mounting groove 321.

[0070] When the deadbolt 310 is in the second or third position, a portion of the deadbolt toggle 360 ​​can be embedded in the second mounting groove 322, that is, the deadbolt connector 320 can be connected to the deadbolt toggle 360 ​​through the second mounting groove 322.

[0071] With this configuration, without changing the installation method of the deadbolt 360 and the deadbolt tongue, the deadbolt connector 320 can be connected to the deadbolt 360 regardless of whether the deadbolt connector 320 is in the first, second, or third position.

[0072] In other embodiments, the deadbolt connector 320 may only have a first mounting groove 321. When the deadbolt operating member 310 is in the first position, second position, or third position, the deadbolt connector 320 is connected to the deadbolt actuating member 360 through the first mounting groove 321. In this case, it is necessary to change the installation method of the deadbolt actuating member 360 and the deadbolt tongue so that the deadbolt tongue can adapt to the installation position and installation angle of the deadbolt actuating member 360.

[0073] Optionally, the first mounting slot 321 and the second mounting slot 322 can be perpendicular to each other. In this way, regardless of whether the deadbolt 310 is in the first, second, or third position, the deadbolt actuator 360 can be kept in a vertical position, thus eliminating the need for additional parts to adjust the mounting position of the deadbolt actuator 360.

[0074] Here, when the handle 200 is deflected to the left, the deadbolt 310 moves synchronously to the second position with the handle 200, and the moving component 330 can move synchronously with the handle 200. At this time, the moving component 330 can drive the deadbolt connector 320 to rotate 90° in the first direction, so that the second mounting groove 322 of the deadbolt connector 320 is opposite to the deadbolt actuator 360, so that the deadbolt connector 320 is connected to the deadbolt actuator 360 through the second mounting groove 322.

[0075] When the handle 200 is deflected to the right, the deadbolt operation member 310 moves synchronously to the third position with the handle 200, and the moving component 330 can move synchronously with the handle 200. At this time, the moving component 330 can drive the deadbolt connector 320 to rotate 90° in the opposite direction of the first direction, so that the second mounting groove 322 of the deadbolt connector 320 is opposite to the deadbolt actuator 360, so that the deadbolt connector 320 is connected to the deadbolt actuator 360 through the second mounting groove 322.

[0076] In this embodiment, the distance between the first position and the second position can be 11.8 mm, and the distance between the first position and the third position can also be 11.8 mm. The first gear 340 has 15 teeth and a module of 1, the second gear 350 has 15 teeth and a module of 1, so that when the moving component 330 has a travel distance L of 11.8 mm, it can drive the anti-locking connector 320 to rotate 90°. Here, the travel distance L ≈ 3.14 × 15 × 90° / 360°.

[0077] In an optional embodiment, the second gear 350 may be provided with an installation alignment mark 351. When the anti-locking operation member 310 is in the first position, the installation alignment mark 351, the center point of the first gear 340, and the center point of the second gear 350 can be located on the same straight line. With this configuration, the installation alignment mark 351 can serve as an indicator when assembling the first gear 340 and the second gear 350, so as to facilitate accurate installation of the first gear 340 and the second gear 350.

[0078] Of course, the second gear 350 may not have the installation alignment mark point 351.

[0079] In an optional embodiment, the deadbolt connector 320 may also be provided with a first connecting hole 323 and a second connecting hole 324. The first connecting hole 323 may communicate with the first mounting groove 321, and the second connecting hole 324 may communicate with the second mounting groove 322. The axis of the first connecting hole 323 and the axis of the second connecting hole 324 may both be perpendicular to the rotation axis of the deadbolt connector 320.

[0080] The locking mechanism 300 may further include a connecting pin 370. When the locking operation member 310 is in the first position, the locking actuating member 360 can be connected to the second connecting hole 324 via the connecting pin 370; when the locking operation member 310 is in the second or third position, the locking actuating member 360 can be connected to the first connecting hole 323 via the connecting pin 370. Here, the locking actuating member 360 is provided with a third connecting hole 361, through which the connecting pin 370 can pass.

[0081] This configuration improves the connection stability between the deadbolt 360 and the deadbolt connector 320.

[0082] Of course, the first connecting hole 323 and the second connecting hole 324 may not be provided on the deadbolt connector 320, the deadbolt mechanism 300 may not include the connecting pin 370, and the deadbolt actuator 360 is only inserted into the deadbolt connector 320 through the first mounting groove 321 or the second mounting groove 322.

[0083] Optionally, the connecting pin 370 can be a cotter pin. This securely connects the deadbolt 360 and the deadbolt connector 320, providing a certain holding force to prevent relative movement or loosening between the deadbolt 360 and the deadbolt connector 320. Furthermore, since the cotter pin has an opening, it can deform under force, thus facilitating installation and disassembly.

[0084] Based on the deadbolt mechanism 300 provided in the embodiments of this application, the embodiments of this application also provide a lock, which may include a base 100, a handle 200, a deadbolt tongue and the deadbolt mechanism 300 described in any of the above embodiments. The handle 200 may be connected to the base 100, the deadbolt actuating member 360 of the deadbolt mechanism 300 may be connected to the deadbolt tongue in a transmission manner, the deadbolt connecting member 320 of the deadbolt mechanism 300 is rotatably disposed on the base 100, the deadbolt operating member 310 is rotatably disposed on the handle 200, and the moving component 330 is slidably disposed on the handle 200.

[0085] In this embodiment, the handle 200 is used to connect to the door body 500 and the base 100, so as to allow the user to hold the handle 200 to open and close the door. Here, the handle 200 can be a rear handle, that is, the handle 200 can be located on the inside of the door body 500.

[0086] The beneficial effects achieved by the lock provided in this application embodiment are consistent with the beneficial effects achieved by the deadbolt mechanism 300 provided in this application embodiment, and will not be repeated here.

[0087] In an optional embodiment of this application, one of the moving component 330 and the handle 200 may be provided with a strip groove 334, and the other may be provided with a first sliding member 240. The first sliding member 240 may be located within the strip groove 334, and the first sliding member 240 and the strip groove 334 may slide relative to each other. Here, the length direction of the strip groove 334 may be the same as the offset direction of the handle 200.

[0088] Optionally, the movable component 330 may be provided with a strip groove 334, and the handle 200 may be provided with a first sliding member 240. With this configuration, since the movable component 330 is relatively thin, it is easier to process the strip groove 334.

[0089] In an optional embodiment, the handle 200 may include a handle body 210, an internal support 220 disposed on the handle body 210, and a decorative cover 230 covering the internal support 220. The handle body 210 may be connected to the base 100, the moving component 330 may be disposed on the internal support 220, and the deadbolt 310 may be rotatably disposed on the internal support 220. At least a portion of the deadbolt 310 may pass through the decorative cover 230 to extend beyond the handle 200, thereby facilitating user operation.
