DETAILED DESCRIPTION

[0042] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that, under the premise of no conflict, the following described embodiments or technical features can be combined in any manner to form new embodiments.

[0043] In the description of the present application, it should be noted that, for orientation words, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0044] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0045] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] The existing combination toy has the following defects: the current combination toy generally adopts a mode similar to a jigsaw puzzle, i.e., a corresponding protrusion and a through groove are arranged on the structure and the connecting piece respectively to realize the splicing, the protrusion needs to be inserted into the through groove in the axial direction, and the clamping is realized by deformation, which is relatively inconvenient, and after a long time of use, the protrusion and the through groove are prone to plastic deformation, thereby affecting the connection stability, and the connection mode limits the relative movement and relative rotation between the two after the splicing is completed, and the flexibility is poor and not convenient.

[0047] As an improvement, as shown in the accompanying drawings, Figures 1-23 the preferred embodiment of the present application is:

[0048] A combination toy comprises a structure 1 and a connecting piece 2, the structure 1 is provided with at least one connecting groove 11, the connecting piece 2 is adapted to enter and exit the connecting groove 11 in the radial direction, the inner wall of the connecting groove 11 is provided with a clamping protrusion 12, the connecting piece 2 is provided with a clamping groove 21, the clamping protrusion 12 is adapted to be inserted into the clamping groove 21 and clamped with the clamping groove 21, and the structure 1 and the connecting piece 2 are adapted to rotate relative to each other with the clamping protrusion 12 as the hinge center.

[0049] In the prior art, the protrusion needs to be inserted into the through groove in the axial direction, that is, sufficient operating space needs to be left in the axial direction of the position where the connecting piece 2 needs to be installed, but when building a complex structure, the structure 1 is often spliced in the axial direction of the position, at this time it is difficult to smoothly realize the connection between the connecting piece 2 and the structure 1, which is very inconvenient. To this end, the present application adopts the technical means of arranging the connecting groove 11 which can be inserted in the radial direction on the structure 1 and arranging the corresponding connecting piece 2, thereby improving the traditional axial insertion to radial insertion, so that the connecting piece 2 and the structure 1 can be connected in the same horizontal plane without occupying longitudinal space, and the operation is more convenient.

[0050] Further, in the prior art, the main way to realize clamping is through the extrusion deformation of the protrusion and the through groove, and during the insertion process, the protrusion as a whole deforms with the inner wall of the through groove, the force is large, and it is laborious to insert, which is very inconvenient for children. To this end, the structure 1 and the connecting piece 2 in the present application are connected by the clamping protrusion 12 and the clamping groove 21, only the clamping protrusion 12 part will be extruded with the connecting piece 2, so this way is more labor-saving and more convenient to operate, and the use of extrusion deformation of the protrusion and the through groove will inevitably cause plastic deformation after a long time of use, at this time the force between the protrusion and the through groove will be smaller, which will affect the stability of the connection, and the clamping protrusion 12 and the clamping groove 21 in the present application can effectively avoid this problem.

[0051] More importantly, in the prior art, when the structural member 1 and the connecting member 2 are combined, the relative position between the two is completely fixed, that is, the relative position of the structural member 1 and the connecting member 2 after being connected is fixed, and the only human-operable space is the combination and disassembly, which is low in flexibility and relatively rigid. In this regard, the clamping protrusion 12 in the present application can also serve as the hinge center for the relative rotation of the structural member 1 and the connecting member 2, so that after being combined, the user can still manually rotate the structural member 1, thereby building more shapes, being higher in flexibility, and being more diverse in play.

[0052] As shown in Figure 4 and Figure 5 , in the present embodiment, the clamping protrusion 12 comprises a limiting section 121, and the clamping groove 21 comprises a limiting cavity 211, when the connecting member 2 is inserted into the connecting groove 11, the limiting section 121 is adapted to be inserted into the limiting cavity 211 and clamped with the limiting cavity 211. The above structure is simple, easy to operate and stable.

[0053] Further, as shown in Figures 4-8 , in the present embodiment, the clamping groove 21 further comprises a guide cavity 212 extending outward from the limiting cavity 211, the limiting section 121 is adapted to be preferentially inserted into the guide cavity 212, and the guide cavity 212 is adapted to guide the limiting section 121 into the limiting cavity 211, and the clamping protrusion 12 further comprises a reinforcing section 122 extending inward from the limiting section 121, and the reinforcing section 122 is adapted to be inserted into the guide cavity 212 and clamped with the guide cavity 212. The guide cavity 212 functions to realize the pre-positioning of the limiting section 121, when the limiting section 121 is inserted into the clamping groove 21, it will be directly inserted into the guide cavity 212, and along the guide cavity 212, the limiting section 121 can be smoothly inserted into the limiting cavity 211, thereby facilitating the operation of the user, and the limiting section 121 is further provided with the reinforcing section 122 adapted to the guide cavity 212, when the limiting section 121 cooperates with the limiting cavity 211, the reinforcing section 122 will simultaneously realize the cooperation with the guide cavity 212, thereby further increasing the stability during connection.

[0054] As shown in Figure 4As shown, in the embodiment, the limiting section 121 comprises a first curved surface 1211 and a second curved surface 1213 respectively arranged at the front and rear ends, and a flat surface 1212 arranged in the middle. The curved surfaces arranged at the front and rear ends of the limiting section 121 have the following effects: 1. When the connecting piece 2 is inserted, the connection between the limiting section 121 and the clamping groove 21 is more smooth and labor-saving; 2. When the limiting section 121 is rotated, the front end and the rear end of the limiting section 121 preferably contact the inner wall of the limiting cavity 211, and the curved surface can make the resistance of the inner wall of the limiting cavity 211 to the limiting section 121 smaller when rotating, that is, effectively ensure that the connecting piece 2 and the structural piece 1 can rotate relatively, and the rotation is more smooth and labor-saving. The flat surface 1212 has the effect that when the limiting section 121 contacts the clamping groove 21, the contact part is mainly the flat surface 1212, and the smooth flat surface can make the resistance smaller when contacting, thereby facilitating insertion.

[0055] Further, as shown in Figure 3 In the embodiment, the thickness of the connecting piece 2 is X1, and the width of the connecting groove 11 is X2, and X1 is less than X2. The above structure makes the connecting piece 2 and the inner wall of the connecting groove 11 have a certain gap, so that when inserted, the surface of the connecting piece 2 does not contact the inner wall of the connecting groove 11, and no friction force is generated, thereby making the insertion of the connecting piece 2 more labor-saving and smooth.

[0056] The more important effect of the above structure is that, as shown in Figure 9 When the connecting piece 2 is completely inserted into the connecting groove 11, because the connecting piece 2 and the inner wall of the connecting groove 11 have a certain gap, the limiting section 121 will not be completely inserted into the limiting cavity 211, and the upper surface of the limiting section 121 will be slightly higher than the surface of the connecting piece 2, so that the contact point between the front end inner wall of the limiting cavity 211 and the limiting section 121 is on the first curved surface 1211 at this time, thereby making the limiting section 121 more smoothly rotate out of the limiting cavity 211 when the connecting piece 2 and the structural piece 1 rotate relatively.

[0057] Further, as shown in Figure 11 and Figure 12 In the embodiment, the width of the limiting section 121 is X5, and the width of the limiting cavity 211 is X4, and X5 is less than X4. The above structure makes the limiting section 121 and the inner wall of the limiting cavity 211 have a certain gap when the limiting section 121 is inserted into the limiting cavity 211, so that the side wall of the limiting section 121 does not contact the inner wall of the limiting cavity 211 at the initial stage of rotation, and when the limiting section 121 contacts the inner wall of the limiting cavity 211, the limiting section 121 has actually rotated a certain angle, at this time, only the first curved surface 1211 and the second curved surface 1213 will contact the inner wall of the limiting cavity 211, thereby effectively reducing the resistance of the inner wall of the limiting cavity 211 to rotation.

[0058] Further, as shown inFigure 10 As shown in the drawings, in the embodiment, the length of the flat part 1212 is X3, and the width of the limiting cavity 211 is X4, X3 is less than X4. The above structure makes the flat part 1212 unable to separate from the limiting cavity 211 even when the limiting section 121 is perpendicular to the limiting cavity 211. Although not shown in the drawings, the clamping protrusion 12 is actually part of the structural member 1, and the thickness of the connecting member 2 is greater than the vertical distance between the two clamping protrusions 12 in the connecting slot 11. Therefore, when the connecting member 2 rotates, the limiting section 121 and the clamping member are always in a state of mutual extrusion. Therefore, when it is ensured that the flat part 1212 cannot separate from the limiting cavity 211, it can effectively prevent the connecting member 2 from separating from the clamping slot 21 when rotating, that is, it ensures the connection stability of the connecting member 2 and the structural member 1 in any state.

[0059] Further, in the embodiment, the connecting slot 11 is opened on at least one end surface of the structural member 1 in the axial direction. The above structure is used to provide the required space when the connecting member 2 and the structural member 1 rotate relative to each other. Whether one opening or two openings is set can be set according to actual needs. Of course, in a set of combination toys, all the above types of structural members 1 can also be included. It is worth mentioning that in the combination toy, a cover plate 4 is provided which can be detachably installed on the end surface of the structural member 1. Therefore, when the connecting member 2 and the structural member 1 do not need to be rotated, the cover plate 4 can be used to close the opening, thereby locking the rotation space.

[0060] Further, in the embodiment, the curvature of the first curved part 1211 is greater than the curvature of the second curved part 1213. The above structure can increase the resistance when the top end of the limiting section 121 abuts against the top end of the limiting cavity 211, thereby preventing the connecting member 2 from being inserted too deeply. On the other hand, it can reduce the resistance when the connecting member 2 is pulled out of the connecting slot 11, thereby facilitating the disassembly of the structural member 1 and the connecting member 2.

[0061] Further, in order to increase the connection mode of the structural member 1 and the connecting member 2, as shown in Figure 2 , Figure 13 and Figure 14 , in the embodiment, the structural member 1 is internally provided with a mounting cavity 13, the mounting cavity 13 is internally provided with a mounting seat 3, the mounting seat 3 is circumferentially limited with the structural member 1, and the mounting seat 3 is provided with a insertion slot 31. The mounting cavity 13 is opened on one end surface of the structural member 1 in the axial direction, and the connecting member 2 is suitable for clamping with the insertion slot 31. The above structure makes the connecting member 2 also axially inserted into the structural member 1, thereby realizing the connection with the structural member 1. Moreover, the mounting seat 3 is circumferentially limited with the structural member 1. Therefore, through the connecting member 2, the rotation can be transmitted to the structural member 1. In the embodiment, the specific way to realize the circumferential limitation is to set corresponding protrusions and grooves on the mounting cavity 13 and the mounting seat 3.

[0062] It is worth noting that in this embodiment, the mounting cavity 13 is only open on one end face of the structural member 1. However, two mounting cavities 13 can be provided on a structural member 1. Therefore, the connector 2 can still be inserted into the structural member 1 axially from both end faces. Of course, one such mounting cavity 13 can also be provided on the structural member 1.

[0063] Furthermore, such as Figure 14 As shown, in this embodiment, the way to achieve the locking effect between the connector 2 and the mounting base 3 is to set the same locking protrusion 12 as described above in the slot 31. This structure is simple and stable.

[0064] like Figures 15-17 As shown, in a modified embodiment of the above embodiment, the mounting cavity 13 has openings on both end faces of the structural member 1 along the axial direction, that is, the mounting cavity 13 penetrates the structural member 1, so that the connector 2 can be inserted into the slot 31 axially from both end faces of the structural member 1, and the connector 2 is adapted to be locked with the slot 31. In this modified embodiment, the specific way to achieve circumferential limiting is that the inner wall of the mounting cavity 13 and the outer wall of the mounting base 3 are pressed against each other.

[0065] Specifically, in this embodiment, the mounting base 3 is provided with a clamping structure 32 inside. The clamping structure 32 is hollow inside, thereby forming a slot 31. The clamping structure 32 includes at least two separately arranged clamping strips 321, and the clamping strips 321 are connected to the mounting base 3 body through an elastic connecting rib 323. The clamping strips 321 are adapted to be combined to form a ring structure. When the connector 2 is inserted into the slot 31, the connector 2 is adapted to abut against the clamping strips 321.

[0066] Since the mounting cavity 13 is a through structure, it is impossible to set the length range of the connecting strip insertion. Therefore, if the connection method of the snap-fit ​​protrusion 12 and the snap-fit ​​groove 21 is still desired, multiple snap-fit ​​grooves 21 need to be set along the length of the connecting strip, which is inconvenient. Therefore, the inventors of this application designed another embodiment, which mainly achieves clamping by mutual compression between the clamping structure 32 and the outer wall of the connecting strip. Furthermore, the clamping structure 32 includes at least two separately arranged clamping strips 321, and the clamping strips 321 are connected to the mounting base 3 body by elastic connecting ribs 323. Therefore, the clamping structure 32 of this application has a certain rotation adjustment function.

[0067] In addition, such as Figure 18 and Figure 19As shown, the clamping structure 32 can also adopt another embodiment, in which the inner wall of the clamping strip 321 is provided with inwardly protruding clamping protrusions 322, and the connecting member 2 is adapted to abut against the clamping protrusions 322 when inserted into the slot 31. The above mechanism is more suitable for wrapping the connecting member 2 and is more stable after the overall combination, but the resistance is also increased accordingly. Therefore, the selection of the embodiment can be selected according to the actual situation.

[0068] Therefore, the structural member 1 can adopt various embodiments, and the installation cavity 13 with an opening or the through installation cavity 13 can be selected according to actual needs, and various types of mounting seats 3 can be arranged in the installation cavity 13, and the parts are detachably connected. Therefore, all parts can be included in a set of combination toys during actual production, and the user can assemble according to the needs during actual use, which is more flexible.

[0069] As shown in the drawings, Figure 20 In this embodiment, the connecting member 2 is provided with a plurality of insertion holes 22 penetrating the connecting member 2 along the radial direction of the connecting member 2, and the other connecting member 2 is adapted to be inserted into the insertion hole 22 along the axial direction and clamped, so that the connecting members 2 are adapted to be combined with each other, and a plurality of connecting members 2 are adapted to be combined to form a transmission structure for transmitting rotation. Therefore, in this embodiment, the connecting member 2 can not only be connected with the structural member 1, but also be connected between the connecting members 2, and through combination, the connecting member 2 can be combined into a transmission structure, so that the combination toy can be assembled into a three-dimensional structure with linkage function of each part, and the play is more diverse and the intelligence development of children is higher.

[0070] In addition, in this embodiment, the combination toy further comprises a cover plate 4 adapted to be detachably mounted on the end face of the structural member 1, and when the cover plate 4 is mounted on the structural member 1, the cover plate 4 is adapted to limit the parts in the structural member 1 from being separated from the structural member 1, and the cover plate 4 is provided with a through hole 41 for the connecting member 2 to be inserted axially. The cover plate 4 can close the opening of the structural member 1, thereby locking the rotation space, and can also limit the disengagement of the mounting seat 3, and the connection between the cover plate 4 and the structural member 1 is realized in the form of clamping, which is convenient and stable.

[0071] Further, as shown in the drawings, Figure 21 and Figure 22 The combination toy further comprises a mounting plate 5, and the front and back surfaces of the mounting plate 5 are respectively provided with a clamping unit 51 and a sliding groove 52, and the cover plate 4, the structural member 1 and the connecting member 2 are adapted to be connected with the mounting plate 5 by cooperating with the clamping unit 51, and the cover plate 4 is adapted to be placed in the sliding groove 52 and adapted to slide in the sliding groove 52.

[0072] As shown in the drawings, Figure 21 and Figure 23As shown in the embodiment, the cover plate 4, the structural member 1 and the connecting member 2 are all adapted to be connected with the mounting plate 5 by cooperating with the clamping unit 51, thus each part in the combination toy can be connected with the mounting plate 5, and the connection is simple and stable, and the user can have any divergent thinking, even the complex three-dimensional structure can be built on the mounting plate 5.

[0073] As shown in the embodiment, the cover plate 4 is adapted to be placed in the sliding groove 52 and to slide in the sliding groove 52. The above structure further increases the playing method of the combination toy, in actual use, the figures can be drawn on the cover plate 4, thus the puzzle can be played on the sliding groove 52, or various development intelligence numbers or patterns can be drawn on the cover plate 4, such as letting the children correspond the cover plates 4 of the same color along the longitudinal direction, or sliding the cover plate 4 to perform some simple mathematical calculation, etc. Figure 22

[0074] The above describes the basic principle, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, the above embodiments and descriptions in the specification are only the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
