[0050] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0051] The first aspect of the present utility model provides a connecting component 101, which is used for assembling toys, especially for aerospace models 10, space station models 20, etc. The assembling toy may include a first component and a second component, and the connecting component 101 is used for connecting the first component and the second component.

[0052] As Figures 1 to 4 , the connecting component 101 according to an embodiment of the present utility model includes a first connecting portion 102, and the first connecting portion 102 includes a first positioning portion 1022 and at least two first positioning protrusions 1021. The first positioning portion 1022 has a first mating surface, the first mating surface extends along the axial direction of the connecting component 101 and is arranged along the circumferential direction of the connecting component 101, and at least two first positioning protrusions 1021 are distributed along the circumferential direction and protrude from the first mating surface.

Among them, the first component may have a first mating portion, the first connecting portion 102 can be sleeved with the first mating portion, and the first positioning protrusion 1021 abuts against the first mating portion in the radial direction. Among them, the first mating surface of the first positioning portion 1022 faces the first mating portion.

[0054] For example, the first mating portion includes a first mounting opening, the outer peripheral surface of the first positioning portion 1022 is configured as the aforementioned first mating surface, the first positioning portion 1022 passes through the first mounting opening, and the first positioning protrusion 1021 abuts against the inner side surface of the first mounting opening; for another example, the first positioning portion 1022 has an interface, the inner peripheral surface of the interface is configured as the aforementioned first mating surface, the first mating portion passes through the interface, and the first positioning protrusion 1021 abuts against the outer side surface of the first mating portion.

[0055] The connecting component 101 according to an embodiment of the present utility model can realize the quick connection between the first component and the second component. By fixing with the first positioning protrusion 1021, the contact area between the first connecting portion 102 and the first mating portion can be reduced, avoiding the difficulty in assembling the first connecting portion 102 and the first component due to production errors, avoiding over-positioning, and improving the stability and connection strength of the assembly structure.

[0056] According to the structure of the first positioning portion 1022 in the present utility model and the different assembly methods of the first positioning portion 1022 and the first component, the first mating surface in the present utility model can have different embodiments.

[0057] In some embodiments, the first positioning portion 1022 has an outer peripheral surface, and the first positioning portion 1022 can be configured to pass through a corresponding structure of the first component. Wherein, the outer peripheral surface of the first positioning portion 1022 is configured as a first mating surface. At this time, the stable mating with the corresponding structure can be achieved through the first positioning protrusion 1021 to improve the connection strength.

[0058] Optionally, as Figure 1 and Figure 2 , one end of the first mating surface in the axial direction is provided with a positioning surface 107. The positioning surface 107 is arranged along the periphery of the first mating surface and extends in a direction perpendicular to the first mating surface. The mating surface can be configured to extend towards the outside of the first positioning portion 1022. During the assembly process, the first component can abut against the positioning surface to avoid over-positioning. Among them, the mating surface can be configured as a plane.

[0059] In other embodiments, the first positioning portion 1022 has an inner peripheral surface, and the corresponding structure of the first component can be configured to pass through the inside of the inner peripheral surface of the first positioning portion 1022. The inner peripheral surface is configured as a first mating surface. Of course, the above descriptions are only some embodiments of the present invention and do not limit the protection scope of the present invention. For example, the first positioning portion 1022 can also be configured as a ring, and both the outer peripheral surface and the inner peripheral surface of the first positioning portion 1022 are configured as the first mating surface.

[0060] Optionally, one end of the first mating surface in the axial direction is provided with a positioning surface 107. The positioning surface is arranged along the periphery of the first mating surface and extends in a direction perpendicular to the first mating surface. The mating surface can be configured to extend towards the inside of the first positioning portion 1022. During the assembly process, the first component can abut against the positioning surface to avoid over-positioning. Among them, the mating surface can be configured as a plane.

[0061] Taking the outer peripheral surface of the first positioning portion 1022 being configured as the first mating surface as an example, the structure of the first connecting portion 102 in the present invention can include but is not limited to the following embodiments.

[0062] Embodiment 1

[0063] As Figure 1 and Figure 2 , the first positioning portion 1022 is provided with a cavity, the first positioning portion 1022 is configured as a hollow structure surrounding the cavity, and the outer peripheral surface of the first positioning portion 1022 is configured as the first mating surface. The consumables of the first positioning portion 1022 can be reduced, the weight of the first positioning portion 1022 can be reduced, the molding of the first positioning portion 1022 can be facilitated, the consumables of the first positioning portion 1022 can be reduced, and the cost can be reduced.

[0064] Among them, in the first example, the first positioning protrusion 1021 is provided on the outer peripheral surface of the first positioning portion 1022. In the second example, the first positioning portion 1022 includes multiple segments distributed around the cavity, and the outer side surface of at least one segment is provided with the first positioning protrusion 1021. When the first connecting portion 102 is assembled and connected to the first component, the first positioning portion 1022 can elastically deform, and the abutting strength between the first positioning protrusion 1021 and the inner peripheral surface of the first mounting opening can be improved, which facilitates the assembly and disassembly of the first connecting portion 102 and the first component. In the third example, the first positioning portion 1022 includes multiple segments distributed around the cavity, and the first positioning protrusion 1021 is provided between adjacent segments. When the first connecting portion 102 is assembled and connected to the first component, the segment provided with the first positioning protrusion 1021 can elastically deform, so as to stably abut the first positioning portion 1022 against the inner peripheral surface of the first mounting opening, facilitating the assembly and disassembly of the first connecting portion 102 and the first component. In the fourth example, as Figure 2 , the first positioning portion 1022 is provided as a closed or unclosed ring extending around the cavity, and the first positioning protrusion 1021 is provided on the outer peripheral surface of the first positioning portion 1022. The stable connection between the first connecting portion 102 and the first component can be realized, and the stability and structural strength of the cooperation between the first connecting portion 102 and the first component can be improved. In the fifth example, the first positioning portion 1022 is provided as a closed or unclosed ring extending around the cavity, the first positioning protrusion 1021 is provided on the outer peripheral surface of the first positioning portion 1022, and the first positioning portion 1022 has a slot 1033, and the slot 1033 is provided on at least one side of the first positioning protrusion 1021 along the circumferential direction of the first positioning portion 1022. When the first connecting portion 102 is assembled and connected to the first component, the first positioning portion 1022 can elastically deform, so as to stably abut the first positioning portion 1022 against the inner peripheral surface of the first mounting opening, facilitating the assembly and disassembly of the first connecting portion 102 and the first component.

[0065] In addition, as Figure 1 and Figure 2, the first connecting portion 102 may include reinforcing ribs to improve the structural strength of the first connecting portion 102. In some examples, the first connecting portion 102 further includes a first reinforcing rib 1051, and the first reinforcing rib 1051 connects to the inner peripheral surface of the first positioning portion 1022. This can improve the structural strength of the first positioning portion 1022, facilitating the socket fitting of the first positioning portion 1022 inside the first mounting opening, achieving stable assembly of the first positioning portion 1022 and the first component, and enhancing the structural strength and stability of the connection between the first component and the second component. In still other examples, the first connecting portion 102 further includes an annular rib 1053 and a second reinforcing rib 1052. The annular rib 1053 is provided inside the first positioning portion 1022, and the second reinforcing rib 1052 is connected between the first positioning portion 1022 and the annular rib 1053. This can further improve the structural strength of the first connecting portion 102. By providing the first reinforcing rib 1051, the annular rib 1053, and the second reinforcing rib 1052, during the plugging and unplugging or use process, excessive deformation of the first positioning portion 1022 is avoided, and the surrounding bone of the first positioning portion 1022 is not easily broken after excessive use, thus preventing mating failure. The excessive deformation of the first positioning portion 1022 is avoided, enhancing the service life and strength of the first positioning portion 1022.

[0066] Embodiment 2

[0067] The first positioning portion 1022 is provided as a solid structure, which can improve the structural strength of the first positioning portion 1022, facilitate multiple disassembly and assembly between the first connecting portion 102 and the first component, avoid damage to the first connecting portion 102, and enhance the service life of the first positioning portion 1022 and the structural strength of the connection with the first component.

[0068] Embodiment 3

[0069] At least one end of the first positioning portion 1022 along the axial direction is provided with an end plate. Herein, the first positioning portion 1022 can be provided as a hollow structure or a solid structure, which can effectively reduce the weight and material loss of the first positioning portion 1022 and effectively improve the connection stability between the first positioning portion 1022 and the first component.

[0070] In addition, in the present utility model, through the structural design of the first positioning protrusion 1021, stable and rapid assembly of the first connecting portion 102 and the first component can be conveniently achieved. The structure of the first positioning protrusion 1021 in the present utility model may include but is not limited to the following examples.

[0071] Such as Figures 1 to 4, Example 1, the first positioning protrusion 1021 is set as a strip extending along the axial direction of the first positioning portion 1022. When the first connecting portion 102 is inserted and connected to the first mounting opening, the first positioning protrusion 1021 with a strip structure extending along the axial direction can facilitate the quick assembly of the first connecting portion 102 and the first mounting opening, effectively improving the assembly structure strength and stability between the first connecting portion 102 and the first component.

[0072] For example Figures 1 to 3 , Example 2, the first positioning protrusion 1021 is set as a block spaced apart from both axial ends of the first positioning portion 1022.

[0073] Example 3, the end of the first positioning portion 1022 protrudes from the first positioning protrusion 1021. The end of the first positioning portion 1022 can first cooperate with the first mounting opening to achieve pre-positioning between the first positioning portion 1022 and the first component. When the first connecting portion 102 is assembled with the first component, the end of the first positioning portion 1022 can be first inserted and fitted into the first mounting opening. Since the end of the first positioning portion 1022 protrudes from the first positioning protrusion 1021, the first positioning portion 1022 can be conveniently inserted and fitted into the first mounting opening, thereby completing the pre-positioning of the first positioning portion 1022 and the first component. Subsequently, the first positioning portion 1022 is continuously inserted into the first mounting opening to complete the stable cooperation between the first connecting portion 102 and the first component, so that the quick assembly of the first connecting portion 102 and the first component can be realized, and the stability of the assembly between the connecting portion and the first component can be improved.

[0074] Example 4, for example Figures 1 to 3 , the first positioning protrusion 1021 is set as an inclined surface with gradually decreasing protrusions on both circumferential sides of the first positioning portion 1022. It can reduce the contact area between the first positioning protrusion 1021 and the inner circumferential surface of the first mounting opening, avoid the difficulty in stably assembling the first connecting portion 102 and the first component due to production errors, and at the same time improve the assembly efficiency and connection strength between the first connecting portion 102 and the first component.

[0075] Example 5, for example Figures 1 to 3 , the end face of the first positioning protrusion 1021 is set as a wedge-shaped surface. Combining with the attached Figure 1 , the end face of the first positioning protrusion 1021 is inclined towards the center of the first positioning portion 1022 along the insertion direction of the first connecting portion 102. Here, the insertion direction refers to the direction in which the first connecting portion 102 is inserted into the first mounting opening during the insertion and fitting process between the first connecting portion 102 and the first component. By setting the wedge-shaped guiding structure, when the first connecting portion 102 is inserted into the first mounting opening, it can undergo elastic deformation, so as to facilitate the quick insertion of the first connecting portion 102 into the first mounting opening, effectively improving the assembly efficiency of the first connecting portion 102 and the first component.

[0076] In addition, in order to further achieve the stable assembly of the first connecting portion 102 and the first component, the above examples can be set separately, or at least two of the above examples can be combined to form a new connecting structure, all of which are within the protection scope of the present utility model.

[0077] In some embodiments, such as Figure 2 , the first connecting portion 102 has a first end and a second end close to the second component, wherein the first end is farther from the second component than the second end. The outer side surface of the first positioning portion 1022 includes a first circumferential surface and a second circumferential surface distributed axially from the first end to the second end, and the second circumferential surface is connected to the first circumferential surface and is configured as a straight surface or a gradually expanding inclined surface. Thereby, it can facilitate the connection between the connecting component 101 and the first component, improve the strength of the connecting structure, and also improve the structural strength of the first connecting portion 102.

[0078] Optionally, the height of the first positioning protrusion 1021 in the axial direction is not less than 1 mm. The first connecting rib connected behind the first positioning protrusion 1021 (which can be a complete circle, or an arc or a straight line. The first connecting rib limits the outer shape, but it must be smaller than the inner wall size of the first fitting portion), and the height of the first connecting rib is not less than 1 mm. The number of the first positioning protrusions 1021 can be at least two, and the protrusion height of the first positioning protrusion 1021 relative to the outer circumferential surface of the first positioning portion 1022 is not less than 0.1 mm. Preferably, the protrusion height of the first positioning protrusion 1021 relative to the outer circumferential surface of the first positioning portion 1022 is not less than 0.2 mm. In addition, the radial dimension of the outer circumferential surface of the first positioning portion 1022 is smaller than the radial dimension of the inner circumferential surface of the first mounting opening, and the difference between the radial dimension of the outer circumferential surface of the first positioning portion 1022 and the radial dimension of the inner circumferential surface of the first mounting opening is not less than 0.2 mm.

[0079] Such as Figure 2 and Figure 3 , in some embodiments, the connecting component 101 further includes a second connecting portion 103. The second connecting portion 103 and the first connecting portion 102 are respectively disposed at opposite ends of the connecting component 101. The second connecting portion 103 includes a second positioning portion 1032 and at least two second positioning protrusions 1031. The second positioning portion 1032 has a second mating surface, the second mating surface extends axially along the connecting component 101 and is arranged circumferentially along the connecting component 101, and at least two second positioning protrusions 1031 are distributed along the circumferential direction and protrude from the second mating surface.

[0080] The second connecting portion 103 can be configured to have the same or a similar structure as the first connecting portion 102, and the structure of the second connecting portion 103 can be obtained by referring to the structure of the first connecting portion 102. For example, the second positioning portion 1032 has an outer peripheral surface, and the second positioning portion 1032 can be configured to pass through a corresponding structure of the second component, wherein the outer peripheral surface of the second positioning portion 1032 is configured as a second mating surface. At this time, stable mating with the corresponding structure can be achieved through the second positioning protrusion 1031 to improve the connection strength.

[0081] In some other embodiments, the second positioning portion 1032 has an inner peripheral surface, and the corresponding structure of the second component can be configured to pass through the inner side of the inner peripheral surface of the second positioning portion 1032, and the inner peripheral surface is configured as a second mating surface. Of course, the above description is only some embodiments of the present invention and is not a limitation on the protection scope of the present invention. For example, the second positioning portion 1032 can also be configured as a ring, and both the outer peripheral surface and the inner peripheral surface of the second positioning portion 1032 are configured as second mating surfaces.

[0082] Optionally, the height of the second positioning protrusion 1031 in the axial direction is not less than 1 mm. The second connecting rib connected behind the second positioning protrusion 1031 (which can be a complete circle, an arc or a straight line. The second connecting rib limits the outer shape, but it must be smaller than the inner wall size of the second mating portion), and the height of the second connecting rib is not less than 1 mm. The number of the second positioning protrusions 1031 can be at least two, and the protruding height of the second positioning protrusion 1031 relative to the outer peripheral surface of the second positioning portion 1032 is not less than 0.1 mm. Preferably, the protruding height of the second positioning protrusion 1031 relative to the outer peripheral surface of the second positioning portion 1032 is not less than 0.2 mm.
