[0002] The deadbolt knob is a key component installed on a door lock, primarily used to control the movement of the bolt, enabling the door lock to lock and unlock. Specifically, the deadbolt knob consists of an interconnected knob and a lever. Users can manually rotate the knob to cause the lever to control the extension or retraction of the bolt, ensuring that the door lock can be quickly locked or unlocked when needed.

[0003] Currently, most deadbolt knobs are fixed to the lock housing using a retaining spring. While this installation method ensures a stable knob installation, it requires specialized retaining spring pliers for assembly, demanding a high level of skill from the installer. Slight mishandling can lead to an insecure or damaged retaining spring, affecting the overall performance and lifespan of the lock. Furthermore, the connection between the knob and the lever mostly relies on cotter pins. Connecting the knob and lever also requires additional tools and complex procedures. This not only increases installation complexity but can also prolong installation time and reduce production efficiency.

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] Figure 1 A schematic diagram of a locking knob 100 according to an embodiment of the present invention is shown. Figure 2 An exploded view of a locking knob 100 according to an embodiment of the present invention is shown. Figure 3 A cross-sectional view of a locking knob 100 according to an embodiment of the present invention is shown below, in conjunction with... Figures 1 to 3 Provide a detailed description.

[0040] like Figures 1 to 3 As shown, the deadbolt knob 100 includes a connecting cap 110, a knob 120, and a lever 130. The connecting cap 110 is located between the knob 120 and the lever 130 to achieve a secure connection between the knob 120 and the lever 130. Figure 4 A schematic diagram of a connecting cap 110 according to an embodiment of the present invention is shown. Figure 3 and Figure 4As shown, the connector 110 includes a first end 111 and a second end 112 opposite to each other. A first socket 113 is provided at the first end 111 of the connector 110, which allows a part of the knob 120 to be inserted. A second socket 114 is provided at the second end 112 of the connector 110, which allows a part of the paddle 130 to be inserted.

[0041] like Figures 1 to 4 As shown, the knob 120 includes an operating part 121 and a rotating shaft part 122. The operating part 121 is the part that the user directly contacts when rotating the knob 120. It can be designed in an ergonomic shape (e.g., cylindrical, cuboid, etc.), and its surface can be provided with anti-slip textures to provide a comfortable grip and facilitate easy rotation of the knob 120. The rotating shaft part 122 is used to connect the knob 120 to the connecting cap 110 and transmit power to the connecting cap 110, the paddle 130, etc. Specifically, one or more first latches 123 are provided on the rotating shaft part 122. The rotating shaft part 122 is inserted into the first insertion hole 113 of the connecting cap 110 and is engaged with the connecting cap 110 by the one or more first latches 123. One end of the paddle 130 ( Figure 2 The right end of the connector is the connecting end 131, used to connect the lever 130 and the connecting cap 110. Specifically, a second snap-fit ​​132 is provided at the connecting end 131 of the lever 130. The connecting end 131 of the lever 130 is inserted into the second through hole of the connecting cap 110 and is engaged with the connecting cap 110 by the second snap-fit ​​132. For the deadbolt knob 100 disclosed in this utility model, the insertion snap-fit ​​connection between the knob 120 and the connecting cap 110 and the lever 130 and the connecting cap 110 allows the installer to quickly connect the various components of the deadbolt knob 100 without the aid of tools, which is beneficial to improving the efficiency of installing the deadbolt knob 100 into the door lock 200.

[0042] Figure 4 A schematic diagram of a knob 120 according to one embodiment of the present invention is shown. Figure 4 As shown, the knob 120 has a hollow structure and a receiving cavity 124, which is located at one end of the rotating shaft 122 (the end away from the operating part 121). Figure 4 An opening is formed at the left end of the middle. Figure 5 A cross-sectional view of a connector cap 110 according to an embodiment of the present invention is shown. Figure 5 As shown, the first socket 113 and the second socket 114 on the connector cap 110 are interconnected, forming a through structure. Figures 3 to 5As shown, after the connecting end 131 of the lever 130 is inserted into the connecting cap 110 through the second through hole, at least a portion of the connecting end 131 extends into the receiving cavity 124 of the knob 120 through the opening at one end of the rotating shaft portion 122. Through the above design, the overall structure of the deadbolt knob 100 is more compact, effectively reducing the amount of material used, thereby reducing production costs.

[0043] According to one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, the first latch 123 can be a first protrusion 123' provided on the outer surface of the rotating shaft portion 122. Correspondingly, one or more first latching holes 115 are provided inside the connecting cap 110, and these first latching holes 115 communicate with the first insertion hole 113. The first latching hole 115 can be a through hole penetrating the wall of the connecting cap 110 (e.g., Figure 2 As shown, the first buckle 123 can also be a blind hole inside the connecting cap 110. When the rotating shaft 122 of the knob 120 is inserted into the first insertion hole 113, the first buckle 123 on the connecting part can precisely engage with the first buckle hole 115 in the connecting cap 110, thereby achieving a stable connection between the knob 120 and the connecting cap 110. Those skilled in the art will readily understand that the number of first buckles 115 can be the same as the number of first buckles 123, so that when the rotating shaft 122 of the knob 120 is inserted into the first insertion hole 113, each first buckle 123 has a matching first buckle 123. In some embodiments, the number of first buckles 115 can also be greater than the number of first buckles 123, thereby reducing assembly difficulty and improving assembly efficiency. In other embodiments, the first buckle 123 can also be a hole (through hole or blind hole) on the outer surface of the rotating shaft 122. Correspondingly, one or more protrusions that cooperate with the first buckle 123 can be provided inside the connecting cap 110 (on the wall of the first insertion hole 113).

[0044] According to one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, one or more elastic arms 125 are formed at the end of the rotating shaft portion 122 away from the operating portion 121, and a first latch 123 is disposed on the outer surface of the corresponding elastic arm 125. Specifically, these elastic arms 125 are formed by opening multiple slots at the end of the rotating shaft portion 122 away from the operating portion 121. Those skilled in the art will readily understand that the elastic arms 125 have a certain elastic deformation capability, which allows the rotating shaft portion 122 to undergo moderate deformation during insertion into the first insertion hole 113, thereby making the connection between the knob 120 and the connecting cap 110 easier. At the same time, the elastic arms 125 can still provide sufficient support for the first latch 123, ensuring a stable engagement between the first latches 123 and the first latch 123, thereby ensuring the stability and reliability of the connection between the knob 120 and the connecting cap 110.

[0045] According to one embodiment of the present invention, such as Figures 1 to 3 As shown, the knob 120 may also include a limiting portion 126, wherein the operating portion 121 is connected to one side of the limiting portion 126. Figures 1 to 3 (right side), the pivot 122 is connected to the other side of the limiting part 126 ( Figures 1 to 3 (Left side of the middle). The outer contour of the limiting part 126 can be designed as a circle, or as a square, regular pentagon, or other polygonal shape. This utility model does not limit the specific shape of the limiting part 126. It should be noted that the width of the limiting part 126 is greater than the width of the rotating shaft part 122. This effectively prevents the knob 120 from completely entering the door lock 200 when the deadbolt knob 100 is assembled into the door lock 200, thereby ensuring that the operating part 121 of the knob 120 is always located outside the door lock 200, which is convenient for user operation. In some embodiments, the operating part 121, the limiting part 126, and the rotating shaft part 122 of the knob 120 can be integrally constructed, for example, by injection molding. In other embodiments, the operating part 121, the limiting part 126, and the rotating part 122 of the knob 120 can be of a split structure, that is, they are manufactured separately and then fixed together by means of bonding, welding, threaded connection, etc.

[0046] According to one embodiment of the present invention, such as Figures 2 to 4 As shown, the second latch 132 can be a second locking hole 132' located at the connecting end 131 of the lever 130. The second locking hole 132' can be a through hole or a blind hole. Correspondingly, a second protrusion 116 is provided inside the connecting cap 110. When the connecting end 131 of the lever 130 is inserted into the second insertion hole 114, the second protrusion 116 in the connecting cap 110 precisely engages with the second locking hole 132', thereby achieving a stable connection between the lever 130 and the connecting cap 110. Optionally, the second protrusion 116 can be located, for example, at the bottom of the first insertion hole 113. When the connecting end 131 of the lever 130 enters the first insertion hole 113 from the second insertion hole 114, the second protrusion 116 precisely engages with the second latch 132. Preferably, there are two second protrusions 116, which are respectively located on opposite sides of the second insertion hole 114 to reduce assembly difficulty and improve assembly efficiency. As will be readily understood by those skilled in the art, in other embodiments, the second buckle 132 may also be a protrusion provided on the surface of the connecting end 131 of the lever 130. Correspondingly, a hole (through hole or blind hole) that mates with the second buckle 132 may be provided inside the connecting cap 110 (the wall of the second insertion hole 114).

[0047] According to one embodiment of the present invention, such as Figure 4As shown, the second protrusion 116 is an elastic structure, which gives it a certain elastic deformation capability. During the process of inserting the paddle 130 into the connecting cap 110 through the second socket 114, the second protrusion 116 can undergo moderate deformation, thereby making the connection between the paddle 130 and the connecting cap 110 easier.

[0048] Figure 6 An exploded view of a portion of the structure of a door lock 200 according to an embodiment of the present invention is shown. Figure 7 A cross-sectional view of a partial structure of a door lock 200 according to an embodiment of the present invention is shown below, in conjunction with... Figure 6 and Figure 7 Provide a detailed description.

[0049] like Figure 6 and Figure 7 As shown, the door lock 200 may include the deadbolt knob 100 as described above. The deadbolt knob 100 can be manually operated by the user to control the extension or retraction of the bolt, ensuring that the door lock 200 can be quickly locked or unlocked when needed.

[0050] According to one embodiment of the present invention, such as Figure 6 and Figure 7 As shown, the door lock 200 also includes a housing 210, which has a connection hole 211. When installing the deadbolt knob 100 onto the door lock 200, the knob 120 can be positioned on the outside of the housing 210, and then the pivot portion 122 of the knob 120 is inserted into the housing 210 through the connection hole 211 (the pivot portion 122 of the knob 120 passes through the connection hole 211), while the limiting portion 126 and the operating portion 121 of the knob 120 remain on the outside of the housing 210. Then, the connecting cap 110 is positioned on the inside of the housing 210 and snapped together with the pivot portion 122 of the knob 120. Under the action of the connecting cap 110, the knob 120 is stably installed on the housing 210. Afterwards, the connecting end 131 of the lever 130 can be inserted into the second insertion hole 114 of the connecting cap 110 to complete the connection between the lever 130 and the connecting cap 110.

[0051] Compared with the prior art, the embodiments of this utility model provide a deadbolt knob 100 and a door lock 200. By providing a first insertion hole 113 and a second insertion hole 114 on the connecting cap 110, a first snap-fit ​​123 on the rotating shaft portion 122 of the knob 120, and a snap-fit ​​on the connecting end 131 of the lever 130, quick engagement between the knob 120 and the connecting cap 110, and between the lever 130 and the connecting cap 110 are achieved. This design not only allows the deadbolt knob 100 to be quickly installed onto the door lock 200, but also eliminates the need for additional tools during installation, greatly simplifying the installation process. Therefore, this utility model effectively solves the problems of complex installation, strong tool dependence, and low production efficiency in the prior art, significantly improving production efficiency and reducing production costs.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
