Description

Technical Field

[0001] This utility model relates to the field of children's toy technology, specifically to a rotating connector for building toys. Background Technology

[0002] Construction toys are toys that children can freely assemble and build. They typically contain parts of various shapes and sizes, such as building blocks and interlocking pieces. Children use their imagination and creativity to combine these parts into various shapes, such as houses, cars, and robots, thereby developing various skills such as fine motor skills, spatial reasoning, and creativity during play.

[0003] When constructing complex structures using sheet-like building blocks, corner connectors are typically required to link adjacent blocks. Currently available corner connectors have fixed angles, which limits the flexibility of constructing complex shapes.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] Purpose of this utility model: The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a rotating connector for building toys with an adjustable rotation angle, which can flexibly meet the requirements of corners in the construction of complex shapes.

[0006] To address the aforementioned technical problems, this utility model discloses a rotating connector for constructing toys. The connector includes a first connector and a second connector that are elastically clamped together axially by an elastic telescopic shaft. The second connector and the first connector are axially opposite to each other and have opposing surfaces perpendicular to the axial direction. A fixed-angle locking structure is formed at the opposing surfaces of the second connector and the first connector. The fixed-angle locking structure includes a protrusion and a set of grooves that mate with the protrusion. The protrusion is formed in either the first connector or the second connector, and the set of grooves is formed in the other connector and is evenly distributed around the axis of the elastic telescopic shaft.

[0007] Specifically, when the first and second connectors are relatively stationary, the protrusion is embedded in one of the grooves to lock the first and second connectors. When an external force drives the first and second connectors to rotate relative to each other, the rotating protrusion moves outward from the groove along the axial direction, and the elastic telescopic shaft adaptively stretches to unlock the first and second connectors. When the external force is removed, the elastic telescopic shaft adaptively contracts, causing the protrusion that crosses the common groove wall between the first and second grooves to embed into the next groove to lock the first and second connectors.

[0008] In some embodiments, there are two or more protrusions.

[0009] In some embodiments, the groove is a beveled groove or an arcuate groove, and the shape of the protrusion is adapted to the groove.

[0010] Preferably, the inclined groove is a V-shaped groove.

[0011] In some embodiments, the elastic telescopic pivot includes a first positioning stage, an outer shaft segment fixedly connected to the first positioning stage, an inner shaft segment with one end located within the outer shaft segment and movable axially relative to the outer shaft segment, a second positioning stage fixedly connected to the other end of the inner shaft segment, and a tension spring. The first positioning stage and the second positioning stage are coaxially arranged. The tension spring is sleeved on the outside of the inner shaft segment, with one end fixedly connected to the inner shaft segment and the other end fixedly connected to the outer shaft segment. The tension spring provides a tensile force to clamp the first connecting body and the second connecting body together axially.

[0012] Specifically, the connector includes a first stepped groove formed in the first connector body and matching the first positioning stage, a second stepped groove formed in the second connector body and matching the second positioning stage, and a through groove formed between the first connector body and the second connector body and communicating the first stepped groove and the second stepped groove. The outer shaft section, the inner shaft section, and the tension spring are all located in the through groove.

[0013] Specifically, both the first positioning stage and the second positioning stage are in the shape of a rotating body.

[0014] Specifically, each of the first connector and the second connector has a plate-shaped block connecting part formed at the end away from the elastic telescopic pivot.

[0015] Specifically, the plate-shaped building block connecting part includes a first clamping piece and a second clamping piece, with a clamping position for clamping the plate-shaped building block formed between the two clamping pieces.

[0016] Beneficial effects:

[0017] 1. The rotating connector of this utility model for building toys has an adjustable angle between the first connector and the second connector, which can flexibly meet the requirements of corners in the construction of complex shapes.

[0018] 2. The rotating connector for a building toy of this utility model utilizes an elastic telescopic shaft to elastically clamp a first connector and a second connector along the axial direction. A fixed-angle locking structure is formed on the opposite surfaces of the second and first connectors. This fixed-angle locking structure includes a protrusion and a set of grooves that mate with the protrusion. The protrusion is formed in either the first or second connector, and the set of grooves is formed in the other of the first and second connectors and is evenly distributed around the axis of the elastic telescopic shaft. When the first and second connectors are relatively stationary, the protrusion is embedded in one of the grooves to lock them. When an external force drives the first and second connectors to rotate relative to each other, the rotating protrusion moves outward from the groove along the axial direction, and the elastic telescopic shaft adaptively stretches to unlock the first and second connectors. When the external force is removed, the elastic telescopic shaft adaptively retracts, causing the protrusion that crosses the common wall between the groove and the next groove to embed into the next groove to lock the first and second connectors. Using this scheme, the unlocking and locking of the first and second connectors can be achieved with simple operation.

[0019] 3. In one embodiment of this utility model, the groove is a sloping groove or an arc-shaped groove, and the shape of the protrusion is adapted to the groove. In this embodiment, the groove and the protrusion are engaged by a sloping or arc-shaped surface. Under the action of external force, the protrusion moves outward along the sloping or arc-shaped surface, making rotation easier. Furthermore, the sloping groove is a V-shaped groove, which facilitates bidirectional rotation. Attached Figure Description

Detailed Implementation

[0031] Example 1

[0032] This utility model provides a rotating connector for a toy construction. See [link / reference] Figures 1 to 4 The connector includes a first connector 100 and a second connector 200 elastically clamped together axially by an elastic telescopic pivot 300. The second connector 200 and the first connector 100 are axially opposite each other and have opposing surfaces perpendicular to the axial direction. A fixed-angle locking structure is formed at the opposing surfaces of the second connector 200 and the first connector 100. The fixed-angle locking structure includes a protrusion 410 and a set of grooves 420 that mate with the protrusion 410. The protrusion 410 is formed in either the first connector 100 or the second connector 200, and the set of grooves 420 is formed in the other of the first connector 100 and the second connector 200 and is evenly distributed around the axis of the elastic telescopic pivot 300. In a particular embodiment, see [reference needed]. Figure 4 A protrusion 41 is formed on the first connector 100. See also Figure 5 A set of grooves 420 are formed on the second connector 200.

[0033] The elastic telescopic pivot 300 can be fixedly connected to either the first connector 100 or the second connector 200, or neither can be fixedly connected.

[0034] See Figure 4 When the first connector 100 and the second connector 200 are relatively stationary, the protrusion 410 is embedded in one of the grooves 420 to lock the first connector 100 and the second connector 200.

[0035] When an external force drives the first connector 100 and the second connector 200 to rotate relative to each other, along the axial direction, the rotating protrusion 410 moves outward from the groove 420, and the elastic telescopic shaft 300 adaptively stretches to unlock the first connector 100 and the second connector 200. When the external force is removed, the elastic telescopic shaft 300 adaptively contracts, causing the protrusion 410, which crosses the common groove wall between the groove 420 and the next groove 420, to embed into the next groove 420 to lock the first connector 100 and the second connector 200.

[0036] Using the above scheme, the first connector 100 and the second connector 200 can be unlocked and locked with simple operation.

[0037] The minimum angle of relative rotation between the first connector 100 and the second connector 200, i.e., the step angle, is a fixed included angle between the centers of two adjacent grooves 420 on the circumference and the axis. In a specific embodiment, see [reference needed]. Figure 6 The connector includes 24 grooves 420, with a fixed step angle of 15 degrees. It should be understood that the number of grooves 420 can be adjusted as needed to meet the step angle requirements of specific applications.

[0038] In one embodiment, two or more protrusions 410 are provided, and when the first connector 100 and the second connector 200 are relatively stationary, each of the two or more protrusions 410 is embedded in a corresponding groove 420. In a particular embodiment, see [reference needed]. Figure 5 There are four protrusions 410, which are evenly distributed around the axis of the elastic telescopic rotating shaft 300.

[0039] In one embodiment, the groove 420 is a sloping groove or an arc-shaped groove. The shape of the protrusion 410 is adapted to the groove 420. In this embodiment, the groove 420 and the protrusion 410 are engaged by a sloping or arc-shaped surface. Under the action of external force, the protrusion 410 moves outward along the sloping or arc-shaped surface, which facilitates rotation.

[0040] In one embodiment, see Figure 7 The inclined groove is a V-shaped groove, which facilitates bidirectional rotation.

[0041] In one embodiment, see Figure 4The elastic telescopic shaft 300 includes a first positioning stage 310, an outer shaft segment 320 fixedly connected to the first positioning stage 310, an inner shaft segment 330 with one end located inside the outer shaft segment 320 and movable axially relative to the outer shaft segment 320, a second positioning stage 340 fixedly connected to the other end of the inner shaft segment 330, and a tension spring 350. The first positioning stage 310 and the second positioning stage 340 are coaxially arranged and jointly define the axis of the elastic telescopic shaft 300. The tension spring 350 is sleeved on the outside of the inner shaft segment 330, with one end fixedly connected to the inner shaft segment 330 and the other end fixedly connected to the outer shaft segment 320. The tension spring 350 provides a tensile force to clamp the first connecting body 100 and the second connecting body 200 together axially.

[0042] In one embodiment, see Figure 4 The connector includes a first stepped groove 110 formed in the first connector 100 and matched with the first positioning stage 310, a second stepped groove 210 formed in the second connector 200 and matched with the second positioning stage 340, and a through groove 500 formed between the first connector 100 and the second connector 200 and connecting the first stepped groove 110 and the second stepped groove 210. The outer shaft section 320, the inner shaft section 330 and the tension spring 350 are all located in the through groove 500.

[0043] In one embodiment, both the first positioning stage stage 310 and the second positioning stage stage 340 are rotary bodies, for example... Figure 4 The cylindrical shape shown.

[0044] In one embodiment, see Figure 1 Each of the first connector 100 and the second connector 200 has a plate-shaped block connecting part 600 at one end away from the elastic telescopic pivot 300.

[0045] In one embodiment, see Figure 1 The plate-shaped building block connecting part 600 includes a first clamping piece 610 and a second clamping piece 620, with a clamping position for clamping the plate-shaped building block 700 formed between the two clamping pieces 610.

[0046] In one embodiment, both the first clamping piece 610 and the second clamping piece 620 are parallel to the axis of the elastic telescopic pivot 300 to allow for planar connection of several plate-shaped blocks 700, such as... Figure 8 As shown, or construct regular polyhedra, for example, a cube can be constructed using square plate blocks 700; a regular tetrahedron can be constructed using equilateral triangular plate blocks 700.

The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
