Detailed implementation manners

[0029] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar reference numerals. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated otherwise that a certain sequence must be followed.

[0031] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0032] As Figures 1-10 shown, an embodiment of the present application provides a non-alignment connection assembly, including: a first connector 10 and a second connector 20.

[0033] An assembly cavity 11 and a plurality of first teeth 12 are provided inside the first connector 10. The plurality of first teeth 12 are fixed to the cavity wall of the assembly cavity 11, and the plurality of first teeth 12 enclose a circle of teeth, and a tooth groove 13 is formed between adjacent first teeth 12.

[0034] At least one second tooth 21 is provided on the second connector 20, and the second tooth 21 meshes with the tooth groove 13. It can be understood that one tooth groove 13 corresponds to one second tooth 21.

[0035] Two inclined first tooth surfaces 14 are formed at one end of the first tooth 12 facing the second connector 20, and the two inclined first tooth surfaces 14 are symmetrically distributed about the axis of the first connector 10.

[0036] In the non-alignment connection assembly in the embodiment of the present application, by providing the inclined first tooth surface 14 on the first tooth 12, when the first tooth 12 and the second tooth 21 are meshed, the guiding effect is directly exerted through the inclined first tooth surface 14, and the second tooth 21 is placed in the tooth groove 13 formed by the first tooth 12. The symmetrically distributed first tooth surfaces 14 enable the first tooth 12 and the second tooth 21 to provide a guiding effect regardless of which first tooth surface 14 during meshing connection. Without considering the connection direction problem when the teeth of the first connector 10 and the second connector 20 are meshed, and without deliberately rotating or turning to a suitable angle, the meshing of the teeth of the first connector 10 and the second connector 20 can be achieved. The designed non-alignment connection assembly effectively improves the connection efficiency when the first connector 10 and the second connector 20 are meshed and connected, and avoids the occurrence of meshing failure.

[0037] It should be noted that when it is necessary to determine the orientation of the first connector 10 and the second connector 20, specifically, reference can be made toFigures 4-10 the orientation directions of the first connecting member 10 and the second connecting member 20 in Figure 4 as an example, the side of the first connecting member 10 facing the second connecting member 20 refers to the downward side of the first connecting member 10. Similarly, the side of the second connecting member 20 facing the first connecting member 10 refers to the upward side of the second connecting member 20.

[0038] such as Figure 3 shown, two inclined second tooth surfaces 22 are formed at one end of the second tooth portion 21 facing the first connecting member 10, and the two inclined second tooth surfaces 22 are symmetrically distributed about the axis of the second connecting member 20. When two symmetrically distributed tooth surfaces (collectively referred to as the first tooth surface 14 and the second tooth surface 22) are provided on both the first tooth portion 12 and the second tooth portion 21, when the first tooth portion 12 and the second tooth portion 21 are engaged, regardless of the docking angle between the first connecting member 10 and the second connecting member 20, the first tooth portion 12 and the second tooth portion 21 can be quickly engaged. For example Figures 1-4 shown, the first connecting member 10 and the second connecting member 20 are in a sleeved relationship. After the first connecting member 10 and the second connecting member 20 are sleeved, if the second tooth portion 21 is directly aligned with the tooth groove 13, the engagement between the first tooth portion 12 and the second tooth portion 21 can be more directly achieved. If the second tooth portion 21 abuts against the first tooth portion 12, since both the first tooth portion 12 and the second tooth portion 21 have two symmetrically distributed and inclined tooth surfaces to play a guiding role, the second tooth portion 21 can also directly slide into the tooth groove 13 through the first tooth surface 14. During this process, there is no need to rotate or turn at an appropriate angle, and the teeth can be quickly aligned and engaged, effectively improving the operation efficiency.

[0039] such as Figures 2-4 shown, a first tooth line 15 is shared on the side where the two first tooth surfaces 14 are close to each other. Along the radial direction from the side far from the axis of the first connecting member 10 to the side close to the axis of the first connecting member 10, the first tooth line 15 is continuously distributed away from the second connecting member 20. And / or, a second tooth line 23 is shared on the side where the two second tooth surfaces 22 are close to each other. Along the radial direction from the side far from the axis of the second connecting member 20 to the side close to the axis of the second connecting member 20, the second tooth line 23 is continuously distributed away from the first connecting member 10.

[0040] The structural design principles of the first tooth line 15 and the second tooth line 23 are the same. Taking Figure 3For example, on the end face of the second connecting member 20 close to the first connecting member 10, a docking plate 24 is provided. On the end face of the docking plate 24 far from the second connecting member 20, a second tooth portion 21 is fixed. The docking plate 24 has a relatively larger radial dimension, which can provide sufficient installation space for the second tooth portion 21. The end face of the docking plate 24 where the second tooth portion 21 is fixed is perpendicular to the axis of the second connecting member 20. Based on the structural layout of the second tooth line 23, the second tooth line 23 is inclined with respect to the end face of the docking plate 24 where the second tooth portion 21 is fixed, that is, the second tooth line 23 is inclined with respect to the axis of the second connecting member 20. Similarly, the first tooth line 15 is also inclined with respect to the axis of the first connecting member 10.

[0041] When at least one of the first tooth line 15 and the second tooth line 23 is inclined, when the first tooth portion 12 and the second tooth portion 21 are engaged, there is a point contact between the first tooth line 15 and the second tooth line 23, with a smaller contact area, which is convenient for the second tooth portion 21 to slide into or enter the tooth groove 13 through the first tooth surface 14 on the first tooth portion 12, and thus the engagement between the first tooth portion 12 and the second tooth portion 21 can be quickly achieved.

[0042] As Figure 3 shown, preferably, the second tooth portion 21 is configured as a pair, and the pair of second tooth portions 21 are symmetrically distributed about the axis of the second connecting member 20. When the second tooth portion 21 is configured as a pair, first of all, the number is small, which can reduce the contact area when all the second tooth portions 21 on the second connecting member 20 are in contact with all the first tooth portions 12 on the first connecting member 10, and is convenient for the second tooth portion 21 to enter the tooth groove 13. It should be noted that here only the situation when the second tooth portion 21 is in contact with the first tooth portion 12 is analyzed, not that when the first connecting member 10 and the second connecting member 20 are connected, the second tooth portion 21 and the first tooth portion 12 will definitely be in contact. In addition, there may also be the situation where the second tooth portion 21 directly enters the tooth groove 13 as mentioned above. The pair of second tooth portions 21 are symmetrically distributed about the axis of the second connecting member 20, so that after the second tooth portion 21 is placed in the tooth groove 13, there is a more stable connection effect between the first connecting member 10 and the second connecting member 20.

[0043] Specifically, the first connecting member 10 is tubular or cylindrical, and the second connecting member 20 is columnar. After the first connecting member 10 and the second connecting member 20 are connected, they can be coaxially distributed, that is, the connected first connecting member 10 and second connecting member 20 can share the same axis.

[0044] For example, as Figures 1-2 and Figure 4As shown, the first connecting member 10 is cylindrical. A plurality of first tooth portions 12 are fixed to the bottom of the cylinder of the first connecting member 10, and the plurality of first tooth portions 12 are distributed in an array around the axis of the first connecting member 10. A second tooth portion 21 is provided on the end face of the second connecting member 20 close to the first connecting member 10. When a docking plate 24 is provided on the second connecting member 20, the second tooth portion 21 can be fixed through the end face of the docking plate 24. The radial dimension or the outer peripheral shape of the docking plate 24 is adapted to the internal structure of the first connecting member 10. At this time, the radial dimension of the second connecting member 20 can be relatively smaller than that of the docking plate 24, and enough assembly space is provided for the second tooth portion 21 through the docking plate 24. The rod-shaped second connecting member 20 can play a connecting role. Take Figure 4 as an example to illustrate the application advantages of the misalignment-free connection assembly designed in the present application. At this time, the specific application scenario of the misalignment-free connection assembly is that the second connecting member 20 acts as a rotating shaft, and the second connecting member 20 is fixedly connected to the member to be rotated 30. When the second connecting member 20 rotates, it can drive the member to be rotated 30 to rotate synchronously. The member to be rotated 30 is, for example, a bobbin, and multiple turns of wire are wound on the bobbin. By rotating the second connecting member 20, the bobbin can release the wire or increase the number of turns of the wound wire. The cylindrical first connecting member 10 is placed upside down and sleeved with the second connecting member 20. The second tooth portion 21 is snapped into the tooth groove 13 to realize the connection between the first connecting member 10 and the second connecting member 20. At this time, rotating the first connecting member 10 can rotate the second connecting member 20 synchronously. When it is necessary to place the second tooth portion 21 in the tooth groove 13, the first connecting member 10 and the second connecting member 20 can be directly sleeved at any angle. This process does not require rotating the first connecting member 10 to a suitable angle. Through the structural design of the second tooth portion 21 and the first tooth portion 12, the misalignment-free function can be realized.

[0045] For another example, as Figures 5-10 shown, the first connecting member 10 is tubular, and a plurality of first tooth portions 12 are fixed to the side wall inside the assembly cavity 11. At this time, the plurality of first tooth portions 12 are also distributed in an array around the axis of the first connecting member 10. The entire internal space of the tubular first connecting member 10 is the so-called assembly cavity 11. At this time, the tubular first connecting member 10 is axially divided into three sections, which are the head section, the tail section, and the middle section in sequence. The plurality of first tooth portions 12 can be fixed to the head section, the tail section, or the middle section of the tubular first connecting member 10. It is specifically set according to the usage requirements, and the present application does not make specific limitations.

[0046] As Figures 5-10 shown, the second tooth portion 21 is fixed to the outer side wall of the second connecting member 20 or the end face of the second connecting member 20 close to the first connecting member 10.

[0047] As Figures 5-7As shown, preferably, a tapered toroidal surface 16 is provided inside one end of the first connecting member 10 close to the second connecting member 20, and the space enclosed by the tapered toroidal surface 16 communicates with the assembly cavity 11. Through the tapered toroidal surface 16, a preliminary guiding function can be exerted, facilitating the entry of the second connecting member 20 or the second tooth portion 21 on the second connecting member 20 into the assembly cavity 11. Combining with the shape design of the first tooth portion 12 and the second tooth portion 21, a further guiding function can be exerted to align the second tooth portion 21 and the tooth groove 13 faster and more conveniently, effectively improving the connection efficiency when the first connecting member 10 and the second connecting member 20 are meshed and connected, and avoiding the occurrence of meshing failure.

[0048] The non-alignment connection assembly designed in this application, in addition to being used for realizing the rotation of the to-be-rotated member 30 introduced above, can also have other application scenarios. For example, it can also be applied to household kettles, electric cookers, etc. A household kettle generally includes a kettle and a base. When boiling water, the kettle filled with water needs to be placed on the base to start the switch to heat the water. In this process, the power connection port at the bottom of the kettle needs to be aligned with the power connection port at the top of the base to heat the water. During the alignment process, the kettle needs to be rotated back and forth to find a suitable angle to align the power connection port of the kettle with the power connection port of the base. However, if the household kettle adopts the non-alignment connection assembly designed in this application, with the first connecting member 10 of this application placed at the power connection port of the base and the second connecting member 20 placed at the power connection port at the bottom of the kettle, during use, the kettle can be directly placed on the base, and the connection between the first connecting member 10 and the second connecting member 20 can be easily achieved without repeatedly rotating the kettle to find a suitable angle.

[0049] The above uses specific examples to elaborate on this application, which is only used to help understand this application and does not limit this application. For those skilled in the technical field to which this application belongs, based on the idea of this application, several simple deductions, deformations or substitutions can also be made.
