Description

Technical Field

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

[0002] As a key component for ensuring the safety and privacy of homes, offices, and other private spaces, the rationality of door lock design and ease of use directly affect the user experience. Among the many door lock structures, the deadbolt function is one of the core mechanisms for achieving internal privacy protection and quick unlocking in emergencies, and it is usually activated by a knob or lever located on the inside of the door.

[0003] In existing door lock designs, the structure of deadbolt knobs generally suffers from several defects that negatively impact user experience. First, most traditional deadbolt knobs are designed to only rotate in one direction (usually clockwise) to lock. This one-way operation design presents significant inconvenience. For left-handed users, the unidirectional rotation contradicts their natural hand habits, resulting in stiff and awkward operation. Furthermore, in emergencies (such as when needing to quickly open the door for escape), users may forget or confuse the correct rotation direction due to panic. This limitation increases operation time and can even trigger panic, posing a safety hazard. Second, existing deadbolt knobs generally lack clear tactile feedback or a distinct sense of position. When users turn the knob, the rotation process is usually smooth and without a sense of progression; there is no clear, perceptible physical positioning between the unlocked and fully locked states. This lack of tactile feedback prevents users from accurately determining whether the knob has been turned to the correct position by feel, often requiring visual confirmation or excessive force in uncertain situations, raising concerns about damaging the internal mechanisms. This not only reduces the certainty and security of the operation, but also makes the entire locking process lack a sense of quality and sophistication. Utility Model Content

[0004] Therefore, it is necessary to address the common defects in the structure of deadbolt knobs in existing door lock designs that affect user experience, and to provide a new type of deadbolt knob structure and door lock.

[0005] A novel door lock deadbolt knob structure includes a lock housing and a manual knob mounted on the lock housing. The manual knob is connected to a bolt, which is used to control the opening and closing of the door lock. The manual knob includes a toggle part, a mounting part, and a connecting part. The toggle part is used to allow the user to rotate the manual knob. The mounting part is used to allow the manual knob to be mounted on the lock housing. The connecting part is used to connect the bolt. The mounting part is annular and includes alternating first protrusions and first grooves. The lock housing includes a through hole that engages with the manual knob. The edge of the through hole is provided with a mating part that engages with the mounting part. The mating part includes alternating second protrusions and second grooves. The second protrusions engage with the first grooves, and the second grooves engage with the first protrusions.

[0006] In use, the aforementioned novel door lock deadbolt knob structure engages with both the first protrusion and the second groove. When the user rotates the manual knob via the toggle mechanism, the knob can be rotated continuously in either a clockwise or counterclockwise direction. Each first protrusion must slide out of the currently engaged second groove and pass over one second protrusion before engaging with the next second groove; similarly, each second protrusion must slide out of the currently engaged first groove and pass over one first protrusion before engaging with the next first groove. This rotation process enables bidirectional continuous rotation and provides the user with clear tactile and audible feedback (a "click" sound), i.e., a distinct "gear feel," allowing the user to confirm whether the operation is in place without visual inspection, thus improving the certainty and experience of the operation. Because the mating structure between the first protrusion and the second groove, and between the first groove and the second protrusion, is periodically symmetrical, the manual knob is no longer limited to a specific direction of rotation. Users can freely choose to rotate the manual knob clockwise or counterclockwise to lock or unlock it, based on their own habits or instinctive reactions in emergency situations. This greatly improves the intuitiveness, convenience, and safety of the operation, especially catering to the needs of left-handed users.

[0007] In one embodiment, the number of the first protrusion, the first groove, the second protrusion, and the second groove are all four.

[0008] In one embodiment, a first sliding surface is provided between adjacent first protrusions and first grooves, and the first sliding surface is a curved surface.

[0009] In one embodiment, a second sliding surface is provided between adjacent second protrusions and second grooves, and the second sliding surface is a curved surface.

[0010] In one embodiment, there are two of each of the first protrusion, the first groove, the second protrusion, and the second groove.

[0011] In one embodiment, the second protrusion is provided with a notch that matches the first protrusion, the notch including a first inclined surface and a second inclined surface that are inclined.

[0012] In one embodiment, the actuating part includes an actuating element and a cover, the cover being circular, and the length of the actuating element being greater than the diameter of the cover.

Detailed Implementation

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] This utility model discloses a novel door lock deadbolt knob structure.

[0019] like Figures 1 to 5 As shown, the novel door lock deadbolt structure includes a lock housing 10 and a manual knob 20 mounted on the lock housing 10. The manual knob 20 is connected to a bolt, which is used to control the opening and closing of the door lock. The manual knob 20 includes a toggle part 21, a mounting part 22, and a connecting part 23. The toggle part 21 is used to allow the user to rotate the manual knob 20. The mounting part 22 is used to mount the manual knob 20 onto the lock housing 10. The connecting part 23 is used to connect the bolt. The mounting part 22 is annular and includes alternating first protrusions 221 and first grooves 222. The lock housing 10 includes a through hole 11 that mates with the manual knob 20. The edge of the through hole 11 is provided with a mating part 12 that mates with the mounting part 22. The mating part 12 includes alternating second protrusions 121 and second grooves 122. The second protrusions 121 mate with the first grooves 222, and the second grooves 122 mate with the first protrusions 221.

[0020] In use, the novel door lock deadbolt structure engages with the first protrusion 221 and the second groove 122, and vice versa. When the user rotates the manual knob 20 via the toggle part 21, the knob can be rotated continuously in either a clockwise or counterclockwise direction. Each first protrusion 221 must slide out of the currently engaged second groove 122 and pass over one second protrusion 121 before engaging with the next second groove 122; similarly, each second protrusion 121 must slide out of the currently engaged first groove 222 and pass over one first protrusion 222 before engaging with the next first groove 222. This rotation process enables bidirectional continuous rotation and provides the user with clear tactile and auditory feedback (a "click" sound), i.e., a clear "gear feel," allowing the user to confirm whether the operation is in place without visual inspection, thus improving the certainty and experience of the operation. Because the mating structure of the first protrusion 221 and the second groove 122, and the first groove 222 and the second protrusion 121, is periodically symmetrical, the manual knob 20 is no longer limited to a specific rotation direction. Users can freely choose to rotate the manual knob 20 clockwise or counterclockwise to lock or unlock it according to their own habits or instinctive reactions in emergency situations. This greatly improves the intuitiveness, convenience, and safety of operation, especially catering to the needs of left-handed users.

[0021] In a preferred embodiment, there are four of each of the first protrusion 221, the first groove 222, the second protrusion 121, and the second groove 122. By setting the number of each of the first protrusion 221, the first groove 222, the second protrusion 121, and the second groove 122 to four, the manual knob 20 provides a clear sense of each gear position for every 90 degrees of rotation. This allows the manual knob 20 to be used to set multiple gear positions such as "on", "45 degrees locked", and "90 degrees locked (full lock)", or to provide more frequent feedback within a single stroke, resulting in a more refined operating feel and higher structural strength and stability.

[0022] Furthermore, a first sliding surface is provided between adjacent first protrusions 221 and first grooves 222, and the first sliding surface is curved. By setting the first sliding surface as curved, the resistance experienced by the user when rotating the manual knob 20 is smooth and gradual, rather than an abrupt step change. This significantly improves the smoothness of the rotation process, brings a better feel, and at the same time reduces the impact and wear between parts, thereby improving the durability of the manual knob 20.

[0023] Furthermore, a second sliding surface is provided between adjacent second protrusions 121 and second grooves 122, and the second sliding surface is curved. By setting the second sliding surface as curved, the second sliding surface cooperates with the first sliding surface, which further ensures the smoothness and fluidity of the entire rotation process of the manual knob 20, thereby achieving a soft and clear gear shift feel and extending the service life of the manual knob 20.

[0024] In another preferred embodiment, the number of the first protrusion 221, the first groove 222, the second protrusion 121, and the second groove 122 are all two. By setting the number of the first protrusion 221, the first groove 222, the second protrusion 121, and the second groove 122 to two, the manual knob 20 provides a tactile feedback for each 180-degree rotation. This is suitable for scenarios where only two distinct states, "on" and "off," are required. This reduces the manufacturing complexity and cost of the new door lock deadbolt knob structure while still providing the core bidirectional operation and basic position feedback functions.

[0025] Furthermore, the second protrusion 121 is provided with a notch 1211 that mates with the first protrusion 221. The notch 1211 includes a first inclined surface 12111 and a second inclined surface 12112. When the user rotates the manual knob 20, the first protrusion 221 first slides into the notch 1211 of the second protrusion 121 and "briefly pauses" in the notch 1211, thus providing the user with the first stage of feedback (e.g., a light "click"), indicating to the user that "the operation has started but is not yet complete." The user needs to continue applying rotational force to make the first protrusion 221 slide out of the notch 1211 and finally pass over the second protrusion 121, falling into the second groove 122, completing the entire action and receiving the second stage of feedback. This two-stage feedback mechanism effectively prevents accidental unlocking or locking due to unintentional or too light touches, improving security.

[0026] The actuating part 21 includes an actuating element 211 and a cover 212. The cover 212 is circular, and the length of the actuating element 211 is greater than the diameter of the cover 212. Because the cover 212 is circular, it has a neat and aesthetically pleasing appearance. The length of the actuating element 211 is greater than the diameter of the cover 212, forming a prominent force application point. This allows the user to easily and accurately locate and actuate the manual knob 20 even when it is difficult to observe (such as in the dark) or when their hands are wet, greatly improving the convenience and reliability of operation.

[0027] This utility model also discloses a door lock, which includes the aforementioned novel door lock deadbolt knob structure. Because this door lock includes the aforementioned novel door lock deadbolt knob structure, it fundamentally solves the problems of traditional door locks having a single deadbolt operation and unclear feedback. This door lock can provide users with a two-way, smooth deadbolt operation experience with clear position feedback, meeting the usage habits of different user groups, and providing a faster and more intuitive operation method in emergencies, thereby significantly improving the door lock's competitiveness, ease of use, and security performance in the market.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
