Description

Technical Field

[0001] This utility model relates to the technical field of assembly toys, and in particular to a multi-hole rod that can be freely assembled at multiple angles. Background Technology

[0002] As a type of educational toy, building blocks are essential for children. Perforated rods are long, colorful plastic rods that interlock at both ends to create all sorts of things. As a core component of the new generation of connector systems, perforated rods primarily serve to construct the main support structure of the product.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing multi-hole rod components are relatively simple and inconvenient to splice different shapes. At the same time, most of the existing plug-in connections are made by direct plug-in interference fit, but this plug-in method is prone to misalignment or failure to fully engage, which reduces the overall splicing effect. Utility Model Content

[0004] The purpose of this invention is to provide a multi-hole rod that can be freely spliced ​​and interlocked at multiple angles.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-angle freely interlocking multi-hole rod includes a multi-hole rod with ends, a multi-hole rod without ends, a wheel axle sleeve, a motor clamp pin, a cross converter, a right-angle fixing clamp, and a multi-head connector. The multi-hole rod with ends and the multi-hole rod without ends have insertion holes for insertion and positioning inside. The multi-hole rod with ends is fixedly connected to its two ends with first positioning plugs for insertion and fixing with the insertion holes.

[0007] The wheel axle sleeve is fixedly connected to one end of the motor clamp pin with a second positioning plug of the same specification as the first positioning plug, and the other end of the wheel axle sleeve is fixedly connected with a positioning axle sleeve for docking with the wheel.

[0008] The other end of the motor clamp is fixedly connected to a cross-shaped fixing plug. One end of the cross-shaped adapter is provided with a first cross-shaped fixing hole that is adapted to the cross-shaped fixing plug. The other end of the cross-shaped adapter is provided with a first cylindrical insertion hole. The first cylindrical insertion hole is used for inserting a round rod.

[0009] By adopting the above technical solution, the multi-hole rod can be extended by mutual insertion through the design of its end and the socket. The end is designed with an expansion groove, which can more effectively fit the socket and significantly improve the smoothness and feel of the insertion process.

[0010] Furthermore, the multi-hole rod with ends is specifically divided into a five-hole rod with ends, a nine-hole rod with ends, and a fifteen-hole rod with ends, while the multi-hole rod without ends is specifically divided into a five-hole rod without ends and a nine-hole rod without ends.

[0011] By adopting the above technical solution, one end is configured with an end structure that is completely identical to that of the porous rod, while the other end is designed with a slender connecting structure. The end structure allows it to be easily plugged into the porous rod, and the connecting structure at the other end can achieve a stable and flexible loose-fit connection with plastic parts such as "wheels", "gears", and "pulleys", which greatly improves the compatibility and practicality of the component.

[0012] Furthermore, the insertion holes are evenly distributed inside the multi-hole rod with ends and the multi-hole rod without ends, and a through groove is provided between adjacent insertion holes inside the multi-hole rod with ends and the multi-hole rod without ends.

[0013] By adopting the above technical solution, a through slot design is incorporated between two adjacent sockets. This innovation not only optimizes the feel of the insertion process, but also gives it the function of fixing board materials (such as KT board, wood cutting board, etc.). A small bevel is provided on each side of the slot. These bevels play a role in smoothly guiding the insertion of board materials, making the operation simpler and more efficient.

[0014] Furthermore, the first positioning plug and the second positioning plug are adapted to the insertion hole. The first positioning plug and the second positioning plug are hollow cylindrical structures with expansion grooves on the side walls. The first positioning plug and the second positioning plug are made of elastic plastic material.

[0015] By adopting the above technical solution, one end is configured with an end structure that is completely identical to that of the porous rod, while the other end is designed with a slender connecting structure. The end structure allows it to be easily plugged into the porous rod, and the connecting structure at the other end can achieve a stable and flexible loose-fit connection with plastic parts such as "wheels", "gears", and "pulleys", which greatly improves the compatibility and practicality of the component.

[0016] Furthermore, one end of the motor clamp pin is fixedly connected to an insertion protrusion that matches the through slot.

[0017] By adopting the above technical solution, one end is configured with an end structure consistent with the porous rod, and an additional straight protrusion is added; while the other end is designed with a cross-shaped connection structure. This end structure ensures that it can be seamlessly plugged into the porous rod.

[0018] Furthermore, one end of the right-angle fixing clip is fixedly connected to a third positioning plug of the same specification as the first positioning plug, and the side wall of the right-angle fixing clip is provided with a second cylindrical insertion hole of the same specification as the first cylindrical insertion hole, and the extension lines of the third positioning plug and the second cylindrical insertion hole are perpendicular to each other.

[0019] By adopting the above technical solution, the round hole of the multi-hole rod is tightly fitted with the end of the right-angle fixing clamp, and the right-angle fixing clamp can connect the multi-hole rods together in pairs through the end set above.

[0020] Furthermore, the multi-head connector has a second cross-shaped fixing hole adapted to the cross-shaped fixing plug in the middle section inside, and a fixing frame is fixedly connected to the outside of the multi-head connector. The fixing frame has a cross-shaped fixing hole adapted to the cross-shaped fixing plug inside, and the cross-shaped fixing hole is used for the insertion and positioning of the cross-shaped plug or the plug rod.

[0021] By adopting the above technical solution, the multi-head connector is a T-wheel, which facilitates full docking and conversion of the whole, increasing the diversity of the overall docking.

[0022] In summary, the beneficial technical effects of this utility model are as follows:

[0023] 1. It adopts an end structure that is completely identical to the multi-hole rod at one end, while the other end is designed with a slender connecting structure. The end structure allows it to be easily plugged into the multi-hole rod, while the connecting structure at the other end can achieve a stable and flexible loose fit connection with plastic parts such as "wheels", "gears", and "pulleys", which greatly improves the compatibility and practicality of the components. The multi-hole rod, which can be freely spliced ​​at multiple angles, also solves the problem of tightness deviation caused by interference fit. Its plugging feel is more stable, and the edges and corners are all rounded, making it more suitable for students to operate and producing an easy docking effect.

[0024] 2. One end features a design identical to the multi-hole rod, with an added straight-line protrusion; the other end has a cross-shaped connection structure. This end design ensures seamless plug-in connection with the multi-hole rod, achieving precise angled insertion through the pre-drilled straight-line slot on the rod. The other end's unique connection structure securely connects with plastic components such as motor clamps, greatly enhancing component compatibility and practical application convenience, giving the product broader and more practical value. The accompanying small connector can use the straight-line protrusion to engage with the straight-line slot on the multi-hole rod to fix the angle and create a stable connection.

[0025] 3. The connector adopts a round tube and cross shaft conversion design. Its internal cross round hole design is an innovative structure that allows the connector to perfectly fit the cross shaft and easily accept the insertion of the round tube. It can be inserted into KT board and cutting board, which has stronger expandability and demonstrates excellent compatibility and practicality, producing a conversion and docking effect.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 2A multi-angle freely interlocking multi-hole rod includes a multi-hole rod with ends 1, a multi-hole rod without ends 2, a wheel axle sleeve 3, a motor clamp pin 4, a cross-shaped adapter 5, a right-angle fixing clip 6, and a multi-head connector 7. The multi-hole rod with ends 1 and the multi-hole rod without ends 2 have insertion holes 11 for positioning. The multi-hole rod with ends 1 has first positioning plugs 12 fixedly connected to both ends for insertion and fixing into the insertion holes 11. One end has an end structure identical to the multi-hole rod, while the other end has a slender connecting structure. The end structure allows for easy insertion into the multi-hole rod, while the connecting structure at the other end allows for a stable yet flexible loose-fit connection with plastic parts such as "wheels," "gears," and "pulleys," greatly improving the compatibility and practicality of the components. The center-to-center distance between adjacent insertion holes on the multi-hole rod is precisely set to 10 mm, which is consistent with the standard LEGO multi-hole rod. With precise geometric matching, this design allows it to be perfectly compatible with standard LEGO mortise bars via wheel axle sleeve 3 connector, thereby greatly expanding the possibilities and creative space for insertion, bringing users a richer and more diverse expansion experience. The multi-hole bar 1 with end caps is specifically divided into five-hole bar with end caps, nine-hole bar with end caps, and fifteen-hole bar with end caps. The multi-hole bar 2 without end caps is specifically divided into five-hole bar without end caps and nine-hole bar without end caps. The insertion holes 11 are evenly distributed inside the multi-hole bar 1 with end caps and the multi-hole bar 2 without end caps. A through slot 13 is provided between adjacent insertion holes 11 inside the multi-hole bar 1 with end caps and the multi-hole bar 2 without end caps. The first positioning plug 12 and the second positioning plug 31 are adapted to the insertion holes 11. The first positioning plug 12 and the second positioning plug 31 are hollow cylindrical structures with expansion grooves on the side walls. The first positioning plug 12 and the second positioning plug 31 are made of elastic plastic material.

[0035] Reference Figure 3 and Figure 4 One end of the wheel axle sleeve 3 and the motor clamp pin 4 is fixedly connected to a second positioning plug 31 with the same specifications as the first positioning plug 12, and the other end of the wheel axle sleeve 3 is fixedly connected to a positioning axle sleeve 33 for docking with the wheel.

[0036] Reference Figure 5 and Figure 6The other end of the motor clamp pin 4 is fixedly connected to a cross-shaped fixing plug 41. One end of the cross-shaped adapter 5 has a first cross-shaped fixing socket 51 that matches the cross-shaped fixing plug 41, and the other end has a first cylindrical socket 52. The first cylindrical socket 52 is used for inserting a round rod. One end has an end structure consistent with the multi-hole rod, and an additional straight-line protrusion structure is added. The other end has a cross-shaped connection structure. This end structure ensures seamless plug-and-play connection with the multi-hole rod. By cleverly utilizing the pre-reserved straight-line through slot on the multi-hole rod, precise angled insertion is achieved. The other end's unique connection structure allows for a firm and tight fit with plastic components such as the "motor clamp." This design greatly enhances the component's stability. The compatibility and convenience in practical applications give the product a wider range of practical value. The connector, specially designed for the conversion between round tubes and cross shafts, features a unique cross-shaped round hole design inside. This innovative structure allows the connector to perfectly fit the cross shaft and easily accept the insertion of round tubes, demonstrating excellent compatibility and practicality. One end of the motor clamp pin 4 is fixedly connected to an insertion protrusion 42 that matches the through slot 13. The through slot 13 design is integrated between two adjacent insertion holes. This innovation not only optimizes the feel during insertion but also gives it the function of fixing sheet materials such as KT board and wood cutting boards. A small bevel is provided on each side of the slot. These bevels play a role in smoothly guiding the insertion of sheet materials, making the operation simpler and more efficient.

[0037] Reference Figure 1 One end of the right-angle fixing clip 6 is fixedly connected to a third positioning plug 61 with the same specifications as the first positioning plug 12. The side wall of the right-angle fixing clip 6 has a second cylindrical insertion hole 62 with the same specifications as the first cylindrical insertion hole 52. The extension lines of the third positioning plug 61 and the second cylindrical insertion hole 62 are perpendicular to each other. The round hole of the multi-hole rod is tightly fitted with the end of the right-angle fixing clip 6. The right-angle fixing clip 6 can connect the multi-hole rods together in pairs through the end provided above. The middle section of the multi-head connector 7 has a second cross-shaped fixing insertion hole 71 that is compatible with the cross-shaped fixing plug 41. The outside of the multi-head connector 7 is fixedly connected to a fixing frame 72. The inside of the fixing frame 72 has a cross-shaped insertion hole 73 that is compatible with the cross-shaped fixing plug 41. The cross-shaped insertion hole 73 is used for the insertion and positioning of the cross-shaped plug or the insertion rod.

[0038] The implementation principle of this embodiment is as follows: First, one end is configured with an end structure completely identical to the multi-hole rod, while the other end is designed with a slender connecting structure. The end structure allows it to be easily plugged into the multi-hole rod, and the connecting structure at the other end can achieve a stable and flexible loose-fit connection with plastic parts such as "wheels", "gears", and "pulleys". That is, the first positioning plug 12 of the multi-hole rod 1 with an end can be plugged into and fixed with the plugging hole 11 inside the multi-hole rod 1 with an end and the multi-hole rod 2 without an end. At the same time, the second positioning plug 31 of one end of the wheel axle sleeve 3 and the motor clamp pin 4 is set to be plugged into and positioned with the plugging hole 11 inside the multi-hole rod 1 with an end and the multi-hole rod 2 without an end, which facilitates the installation of the wheel axle sleeve 3 and the motor clamp pin 4, thereby facilitating a stable and flexible loose-fit connection with plastic parts such as "wheels", "gears", and "pulleys". In addition, the cross hole inside the motor clamp pin 4 and the multi-head connector 7 facilitates plugging into and positioning with the cross-shaped structure, which increases the overall splicing effect.
