[0038] like Figures 1 to 4 As shown, the building block quick connection structure provided by the embodiment of the present application includes a first connection part 10 and a second connection part 20. Figure 3 , Figures 5 to 8 As shown, the first connecting portion 10 is provided with an insertion hole 11, and a plurality of guide ribs 12 are provided on the hole wall of the insertion hole 11 along the circumferential direction, and the extension direction of each guide rib 12 is consistent with the hole axis direction of the insertion hole 11, and a first buckle structure 13 is provided on the inner wall of the insertion hole 11. Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, the second connecting portion 20 is provided with a plug rod 21, and the outer side wall of the plug rod 21 is provided with a second buckle structure 23 and a plurality of guide grooves 22 distributed along the circumferential direction, and the extension direction of each guide groove 22 is consistent with the axial direction of the plug rod 21, and the guide grooves 22 are arranged one by one with the guide ribs 12. The second buckle structure 23 and the first buckle structure 13 are buckled with each other to prevent the plug rod 21 from slipping out of the insertion hole 11.

[0039] The building block quick-connect structure of the present application is applied to the educational toys that need to be assembled by children before they can play. The children only need to insert the plug-in rod 21 of the second connecting part 20 into the plug-in hole 11 of the first connecting part 10 to complete the assembly work. In the building block quick-connect structure, since the hole wall of the plug-in hole 11 is provided with a plurality of guide ribs 12 along the circumferential direction, and the outer side wall of the corresponding plug-in rod 21 is provided with a second buckle structure 23 and a plurality of guide grooves 22 distributed along the circumferential direction, and the guide grooves 22 and the guide ribs 12 are arranged one by one, therefore, when the children insert the plug-in rod 21 into the plug-in hole 11, through the positioning function and the guiding function between the guide groove 22 and the guide rib 12, it is convenient for the children to quickly align the plug-in rod 21 with the plug-in hole 11, and it is also possible for the children to quickly and accurately insert the plug-in rod 21 into the plug-in hole 11, thereby efficiently completing the assembly work, helping to enhance the children's confidence in hands-on operation, and achieving the educational purpose of combining education with entertainment. Furthermore, when a child inserts the plug-in rod 21 into the insertion hole 11 , the second buckle structure 23 and the first buckle structure 13 will be buckled with each other, thereby preventing the plug-in rod 21 from slipping out of the insertion hole 11 , thereby ensuring the connection stability of the building block quick-connect structure.

[0040] like Figure 8 As shown, the insertion hole 11 includes a first hole wall 111, a second hole wall 112, a third hole wall 113 and a fourth hole wall 114 distributed in sequence along the circumferential direction. The first hole wall 111 and the third hole wall 113 are arranged opposite to each other, and the second hole wall 112 and the fourth hole wall 114 are arranged opposite to each other. That is to say, the cross-sectional profile of the insertion hole 11 is roughly rectangular. Therefore, the insertion hole 11 is also called a square hole, so that the first connecting portion 10 is easy to demold during injection molding, and the injection molding process efficiency is high. And, as Figure 6 and Figure 8 As shown, the first hole wall 111 and the third hole wall 113 are each provided with at least one guiding rib 12, and the first buckling structure 13 is provided on the second hole wall 112 and / or the fourth hole wall 114. Corresponding to the contour shape of the insertion hole 11, as shown in FIG. Fig. 9 and Fig.10As shown, the plug-in rod 21 includes a first outer wall 211, a second outer wall 212, a third outer wall 213 and a fourth outer wall 214 which are sequentially distributed along the circumferential direction. The first outer wall 211 and the third outer wall 213 are arranged opposite to each other, and the second outer wall 212 and the fourth outer wall 214 are arranged opposite to each other. The cross-sectional profile of the plug-in rod 21 is also roughly rectangular. Therefore, the plug-in rod 21 is also called a square rod, and the plug-in rod 21 is designed as a central control rod-shaped structure with a hollow cavity 26. In addition, the first outer wall 211 and the third outer wall 213 are respectively provided with a guide groove 22, and the second buckle structure 23 is arranged on the second outer wall 212 and / or the fourth outer wall 214. When the plug-in rod 21 of the second connecting part 20 is inserted into the insertion hole 11 of the first connecting part 10, the square hole can limit the square rod, so that the plug-in rod 21 cannot rotate relative to the insertion hole 11, and the insertion is stable.

[0041] like Fig. 9 and Fig.10 As shown, at one end of the guide groove 22 for inserting the guide rib 12, two opposite groove walls are provided with a first guide slope 221. When the plug-in rod 21 of the second connection part 20 is inserted into the insertion hole 11 of the first connection part 10, the first guide slope 221 is used to guide the end of the guide rib 12 to slide into the guide groove 22. This can greatly facilitate children to insert the plug-in rod 21 into the insertion hole 11, reduce the requirements for children's operating flexibility when connecting the plug-in rod 21 and the insertion hole 11, and enable children to quickly complete the plug-in operation.

[0042] like Figure 8 As shown, the second hole wall 112 is provided with a plurality of first limiting ribs 14 spaced apart from each other, and the extending direction of each first limiting rib 14 is consistent with the hole axis direction of the insertion hole 11. Figure 6 and Figure 8 , the fourth hole wall 114 is provided with a plurality of spaced second limiting ribs 15, and the extension direction of each second limiting rib 15 is consistent with the hole axis direction of the insertion hole 11. When the plug-in rod 21 is inserted into the insertion hole 11, the plurality of first limiting ribs 14 abut against one of the second outer wall 212 and the fourth outer wall 214, and the plurality of second limiting ribs 15 abut against the other of the second outer wall 212 and the fourth outer wall 214 (in the embodiment of the present application, the first limiting rib 14 abuts against the second outer wall 212, and the second limiting rib 15 abuts against the fourth outer wall 214). In other words, the plurality of first limiting ribs 14 and the plurality of second limiting ribs 15 form a clamping state for the plug-in rod 21, and have the function of guiding the plug-in rod 21 to slide into the insertion hole 11, and cooperate with the guiding effect between the guide rib 12 and the guide groove 22, so that children can conveniently, quickly, and accurately insert the plug-in rod 21 into the insertion hole 11.

[0043] Furthermore, each guide rib 12 abuts against the bottom surface of the corresponding guide groove 22. In addition, the first limiting rib 14 abuts against the second outer side wall 212, and the second limiting rib 15 abuts against the fourth outer side wall 214. In this way, the upper, lower, left, and right positions of the plug-in rod 21 relative to the plug-in hole 11 are restricted, and the plug-in rod 21 will not swing freely in the plug-in hole 11, which helps children to complete the plug-in smoothly.

[0044] In some embodiments of the present application, Figure 8 As shown, the number of the first limiting ribs 14 is two, and a first buckle structure 13 is provided between the two first limiting ribs 14. Alternatively, in some other embodiments of the present application, the number of the second limiting ribs 15 is two, and a first buckle structure 13 is provided between the two second limiting ribs 15. Alternatively, in some other embodiments of the present application, the number of the first limiting ribs 14 is two, and a first buckle structure 13 is provided between the two first limiting ribs 14, and the number of the second limiting ribs 15 is two, and a first buckle structure 13 is provided between the two second limiting ribs 15.

[0045] Furthermore, in the embodiment of the present application, the second outer wall 212 and the fourth outer wall 214 are both provided with a second buckling structure 23. Therefore, whether the second outer wall 212 of the plug-in rod 21 is inserted into the insertion hole 11 with the fourth outer wall 214 facing downward, or the fourth outer wall 214 of the plug-in rod 21 is inserted into the insertion hole 11 with the second outer wall 212 facing downward, the plug-in rod 21 can be smoothly inserted into the insertion hole 11 under the joint action of the guiding cooperation between the guide rib 12 and the guide groove 22, and the restriction of the plug-in rod 21 by the first limiting rib 14 and the second limiting rib 15, and the second buckling structure 23 is buckled onto the first buckling structure 13 to restrict the plug-in rod 21 from slipping out of the insertion hole 11.

[0046] like Figure 6 As shown, each first limiting rib 14 has one end facing the opening of the insertion hole 11, each second limiting rib 15 has one end facing the opening of the insertion hole 11, and each guide rib 12 has one end facing the opening of the insertion hole 11. Such a design can make the plug-in rod 21 more smoothly introduced into the insertion hole 11, so that children can quickly and accurately complete the plug-in.

[0047] In the embodiment of the present application, the first buckle structure 13 is a through hole that passes through the outer wall of the first connecting portion 10 and the hole wall of the insertion hole 11. Fig. 9 and Fig.10As shown, the second buckling structure 23 includes an elastic arm 231 and a protrusion 232. The first end of the elastic arm 231 is connected to the plug-in rod 21, and the protrusion 232 is arranged at the second end of the elastic arm 231. A second guide slope 233 is arranged on the side of the protrusion 232 facing the first end of the elastic arm 231. In the process of inserting the plug-in rod 21 into the insertion hole 11, the second guide slope 233 is squeezed by the opening edge of the insertion hole 11, so that the elastic arm 231 is elastically deformed, and the protrusion 232 sinks into the insertion hole 11. When the protrusion 232 moves to the first buckling structure 13 (i.e., the through hole), the protrusion 232 is inserted into the through hole under the elastic force of the elastic arm 231, thereby completing the locking to prevent the plug-in rod 21 from slipping out of the insertion hole 11. When the plug-in rod 21 needs to be pulled out of the insertion hole 11 , the protrusion 232 only needs to be pressed to make the protrusion 232 completely withdraw from the through hole, and then the plug-in rod 21 is pulled out with force to get out of the insertion hole 11 .

[0048] According to another aspect of the present application, a toy (not shown) is provided. Specifically, the toy includes the aforementioned building block quick-connect structure.

[0049] The toy provided in the embodiments of the present application is, for example, a robot dog. The building block quick-connect structure is applied to the assembly of the calf structure of the robot dog, thereby assembling the calf structure of the robot dog conveniently and quickly.

[0050] At this time, in the robot dog, the lower leg structure of the robot dog includes a leg and a foot, and the leg includes a first component 110, a second component 120 and a third component 130. Specifically, the first end 101 of the first component is the first connecting portion 10, and the foot is the second connecting portion 20. Figures 2 to 5As shown, the second end 102 of the first component is provided with an assembly space 103, and the assembly space 103 is used to install the joint motor. The surrounding wall of the assembly space 103 forms a first sleeve structure, and a notch 104 is provided on the top of the surrounding wall of the first sleeve structure, and the inner wall of the assembly space 103 is provided with a connecting ear 105 and a positioning bayonet 106. The second component 120 is provided with a second sleeve structure, and a covering panel 121 extends from the outer wall of the second sleeve structure, and a snap-on protrusion 122 is provided on the inner wall of the second sleeve structure. The first sleeve structure is passed into the sleeve space 123 of the second sleeve structure, and the snap-on protrusion 122 is located in the notch 104. The third component 130 is provided with a positioning buckle 131 and a connecting column 132. The connecting column 132 is locked with the connecting ear 105 by means of the screw 140, so that the third member 130 restricts the second sleeve structure from being separated from the first sleeve structure. At this time, the notch 104 and the edge of the third member 130 form a slide groove, and the snap-on protrusion 122 can slide in the slide groove, that is, the second sleeve structure can rotate relative to the first sleeve structure. When the shutdown motor is installed and placed in the assembly space 103, the second sleeve structure is rotated so that the snap-on protrusion 122 is snapped into the corresponding slot of the joint motor, thereby restricting the joint motor from being separated from the assembly space 103. At this time, the cover panel 121 overlaps with the shaft of the first member 110, and the cover panel 121 can cover the through hole (that is, covers the first snap-on structure 13).

[0051] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
