Technical Field
[0001] This invention relates to the field of toy technology, and more particularly to a quick-release connection structure for a track toy. Background Technology
[0002] Track toys are highly playable toys, typically played in conjunction with toy cars. To enhance playability, track toys usually use track modules of different shapes for assembly and connection, allowing for various assembly methods to change the overall shape of the track. Currently, there are two main methods for connecting the various modules in track toys. One method uses screws or pins to fix two adjacent track modules together. This method suffers from overly complex disassembly and assembly processes, hindering quick disassembly and reassembly and affecting playability. The other method uses snap-fit structures directly on the track modules for assembly and connection. This method requires considerable force to ensure a secure connection between the track modules during disassembly and assembly, making it difficult for younger players to operate and hindering quick disassembly and reassembly of the track modules. Summary of the Invention
[0003] The purpose of this invention is to provide a quick-release connection structure for track toys, specifically a connection structure for track toys that is easy to operate and can be quickly disassembled and assembled.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release connection structure for a track toy, wherein the track toy is composed of several track modules connected end to end, and adjacent track modules are detachably connected by snap-fit protrusions and snap-fit grooves; the snap-fit protrusion includes a snap-fit part and a rotating ejection part, and the snap-fit groove includes a snap-fit slot and a rotating mating slot. After the snap-fit protrusion and the snap-fit groove are inserted and engaged, the snap-fit part and the snap-fit slot can be rotatably engaged and engaged, and the rotating ejection part is correspondingly engaged with the rotating mating slot, and the rotating ejection part is offset from the rotating mating slot when it rotates; the rotating ejection part is provided with an ejection slope, and the angle between the ejection slope and the end plane of the rotating ejection part is 20~25°.
[0005] Specifically, the rotating ejector is located on the outside of the snap-fit protrusion, and the ejector ramp is located on the outer edge of the rotating ejector. When the snap-fit protrusion and the snap-fit groove are inserted and engaged, and the snap-fit protrusion rotates, the ejector ramp of the rotating ejector will push the rotating ejector away from the rotating engagement groove and separate it. At this time, the snap-fit part of the snap-fit protrusion and the snap-fit groove of the snap-fit groove are disengaged from the snap-fit relationship.
[0006] Specifically, the overall shape of the rotating ejector is a centrally symmetrical figure, and the ejector ramps are multiple and arranged in an equidistant circular array on the outside of the rotating ejector.
[0007] Specifically, the front end of the snap-fit protrusion is provided with a first snap-fit part, and the inside of the snap-fit groove of the snap-fit groove is provided with a second snap-fit part that engages with the first snap-fit part. The first snap-fit part and the second snap-fit part are rotatably snap-fitted together.
[0008] Specifically, the first snap-fit part includes a front snap-fit part and an annular snap-fit groove located behind the front snap-fit part.
[0009] Specifically, the second snap-fit part includes at least one snap-fit piece, which extends downward and inward from the upper end of the snap-fit groove. After the snap-fit protrusion is inserted into the snap-fit groove, the end of the snap-fit piece is engaged in the annular snap-fit groove and abuts against the front snap-fit part.
[0010] Specifically, a movable opening is provided on the inner sidewall of the snap-fit groove at the location where the snap-fit piece is set, and the snap-fit piece can be stretched open and pass through the movable opening.
[0011] Specifically, there are multiple snap-fit pieces arranged in a circular array within the snap-fit slot.
[0012] Specifically, the radius of the snap-fit part is 8~12mm, the projected length of the central axis of the ejector ramp is 2.5~3.5mm, and the end width of the rotating ejector part after removing the ejector ramp is 1.1~1.7mm.
[0013] Furthermore, a rotating ejection protrusion is provided inside the rotating mating groove, and a rotating ejection groove corresponding to the rotating ejection protrusion is provided on the rotating ejection part; the rotating ejection protrusion is arc-shaped and concentric with the snap-fit groove; the rotating ejection protrusion is outwardly convex with a higher middle and lower ends.
[0014] The beneficial effects of this invention are as follows: the track modules are detachably connected by snap-fit protrusions and snap-fit grooves, wherein the snap-fit protrusions and snap-fit grooves are fixed by snap-fit parts and snap-fit slots, and are also provided with rotating ejection parts and rotating mating slots for mating connection. By rotating the track module, the rotating ejection part and the rotating mating slot can be separated by offsetting each other, thereby realizing the quick disassembly and assembly of the track modules and improving the playability of the track toy; and the rotating mating slot and the rotating ejection part are also connected by rotating ejection protrusions and rotating ejection slots, which can improve the stability of the connection between the snap-fit protrusions and snap-fit grooves, and provide a rotation offset path for the rotating ejection part and the rotating mating slot to be rotated offset, further facilitating the separation and disassembly of the two.

Detailed Implementation
[0026] Example 1, referring to Figure 1-8 A quick-release connection structure for a track toy is disclosed. The track toy consists of several track modules 10 connected end to end. Adjacent track modules 10 are detachably connected via snap-fit protrusions 1 and snap-fit grooves 2. The snap-fit protrusion 1 includes a snap-fit part 11 and a rotating ejection part 12. The snap-fit groove 2 includes a snap-fit slot 21 and a rotating engagement slot 22. After the snap-fit protrusion 1 and the snap-fit groove 2 are inserted and engaged, the snap-fit part 11 and the snap-fit slot 21 can be rotatably engaged and engaged. The rotating ejection part 12 is engaged with the rotating engagement slot 22, and the rotating ejection part 12 is offset from the rotating engagement slot 22 when it rotates. The rotating ejection part 12 is provided with an ejection slope 121, and the angle between the ejection slope 121 and the end plane of the rotating ejection part 12 is 20~25°.
[0027] This embodiment of the track toy is a magnetic track toy. The track has a sliding groove 100, within which a magnetic sheet is placed. The sliding groove 100 accommodates a small car with magnetic wheels at the bottom. The track module 10 can be configured as a rectangular straight track, an arc-shaped curve, etc., to form tracks with different shapes such as straight, turning, uphill, and downhill sections. The shape of the track can be customized as needed, and this is not a key technology protected by this application and is not limited thereto. The purpose of this application is to protect the connection structure between the track modules 10. Specifically, the track modules 10 are detachably connected via snap-fit protrusions 1 and snap-fit grooves 2. Each track module 10 has snap-fit protrusions 1 and snap-fit grooves 2, and these protrusions 1 and grooves 2 are located at both ends of the track module 10 for connection with adjacent track modules 10. Specifically, after the snap-fit protrusion 1 and the snap-fit groove 2 are connected, the snap-fit portion 11 on the snap-fit protrusion 1 is snapped and fixed with the snap-fit groove 21 of the snap-fit groove 2. Correspondingly, the rotating ejector portion 12 of the snap-fit protrusion 1 is engaged with the rotating engagement groove 22 of the snap-fit groove 2. When it is necessary to separate the snap-fit protrusion 1 and the snap-fit groove 2, it is only necessary to rotate the two track modules 10 relative to each other, so that the snap-fit protrusion 1 and the snap-fit groove 2 rotate relative to each other. When the snap-fit protrusion 1 and the snap-fit groove 2 rotate relative to each other, the rotating ejector portion 12 engages with the rotating engagement groove 22. The slots 22 are staggered and separated from each other, thereby causing the locking part 11 to disengage from the locking slot 21, thus realizing the rapid separation and disassembly of the two track modules 10; wherein, the rotating ejection part 12 is provided with an ejection slope 121. When the locking protrusion 1 and the locking groove 2 are inserted and engaged, and the locking protrusion 1 rotates, the ejection slope 121 of the rotating ejection part 12 facilitates the rotating ejection part 12 to be staggered and ejected from the rotating engagement slot 22. At this time, the locking part 11 of the locking protrusion 1 and the locking groove 21 of the locking groove 2 are disengaged from the locking relationship. Meanwhile, to ensure the stability of the connection between the rotating ejector and the rotating mating groove, and to facilitate their mutual misalignment, the included angle between the ejector ramp and the end plane of the rotating ejector needs to be limited, preferably set to 20~25°. The ejector ramp can be an arc-shaped surface (including outward convexity or inward concavity) or a plane. Therefore, the included angle between the ejector ramp and the end plane of the rotating ejector needs to be further defined as follows: this included angle is the angle between the line connecting the two ends of the central axis of the ejector ramp and the end plane of the rotating ejector. It should be noted that since the two track modules 10 need to rotate relative to each other during disassembly, the snap-fit connection between the snap-fit part 11 of the snap-fit protrusion 1 and the snap-fit groove 21 of the snap-fit groove 2 is rotatable. That is, they are snap-fitted and fixed to each other in the axial direction, and they can rotate relative to each other around their central axis. Therefore, the overall shape of the snap-fit part 11 and the snap-fit groove 21 should be approximately cylindrical.
[0028] Among them, reference Figure 6The radius of the snap-fit part is 8~12mm, the projection length of the central axis of the ejector ramp is 2.5~3.5mm, and the end width of the rotating ejector part after removing the ejector ramp is 1.1~1.7mm.
[0029] In order to facilitate the rotation of the locking protrusion 1 and the locking groove 2, the rotating ejector 12 is positioned on the outside of the locking protrusion 1. This allows for a longer lever arm in the rotational misalignment between the rotating ejector 12 and the rotating groove 22 when the two track modules 10 rotate relative to each other, thereby reducing the force required for rotation and making it easier for younger children to operate. An ejection ramp is located on the outer edge of the rotating ejector.
[0030] In order to ensure that the direction does not need to be confirmed when the snap-fit protrusion 1 and the snap-fit groove 2 are fixedly connected to the track module 10, or to ensure that the track module 10 can still snap-fit when facing different directions, the overall shape of the rotating ejector 12 in this embodiment is a centrally symmetrical figure, and the ejector ramps 121 are multiple and are arranged in an equidistant circular array on the outside of the rotating ejector 12; preferably, the outer edge of the rotating ejector 12 is a square, and there are four ejector ramps 121 and they are arranged at the four corners of the rotating ejector 12.
[0031] Specifically, in this embodiment, the engagement between the latching part 11 and the latching groove 21 adopts the following structure: a first latching part 13 is provided at the front end of the latching part 11 of the latching protrusion 1, and a second latching part 23 is provided inside the latching groove 21 of the latching groove 2 to engage with the first latching part 13. The first latching part 13 and the second latching part 23 are rotatably engaged. Specifically, the engagement structure between the first latching part 13 and the second latching part 23 is as follows: the first latching part 13 includes a front latching part 131 and an annular latching groove 132 located behind the front latching part 131; correspondingly, the second latching part 23 includes at least one latching piece 231, which extends downward and inward from the upper end of the latching groove 21. After the latching protrusion 1 is inserted into the latching groove 2, the end of the latching piece 231 is engaged in the annular latching groove 132 and abuts against the front latching part 131. Furthermore, a movable opening 232 is provided on the inner wall of the snap-fit groove 21 at the location where the snap-fit piece 231 is set. The snap-fit piece 231 can be opened and pass through the movable opening 232. This allows the snap-fit piece 231 to be pushed out by the front snap-fit part 131 into the movable opening when the rotating ejector part 12 and the rotating mating groove 22 are misaligned, preventing the snap-fit piece 231 from being squeezed against the front snap-fit part 131 and increasing friction, thus facilitating the assembly of the two track modules 10. Specifically, multiple snap-fit pieces 231 are arranged in a circumferential array within the snap-fit groove 21 to achieve a good snap-fit fixing effect.
[0032] Example 2, refer to Figure 9-10Based on Embodiment 1, this embodiment adds a rotating ejection protrusion 24 within the rotating mating groove 22, and a rotating ejection groove 14 corresponding to the rotating ejection protrusion 24 on the rotating ejection part 12. The rotating ejection part 12 and the rotating mating groove 22 are connected by the protrusion and groove. This improves the connection stability of the locking protrusion 1 and locking groove 2 at the rotating ejection part 12 and the rotating mating groove 22 after the track modules are assembled. Furthermore, it restricts the rotation path of the rotating ejection part 12 and the rotating mating groove 22 when the two track modules rotate relative to each other, facilitating the rotational offset of the rotating ejection part 12 and the rotating mating groove 22, and further reducing the difficulty of disassembling and assembling the locking protrusion 1 and the locking groove 2.
[0033] Specifically, in this embodiment, the rotating ejection protrusion 24 is arc-shaped and concentric with the snap-fit groove 21. The rotating ejection protrusion 24 is outwardly convex with a higher middle and lower ends. In order to facilitate the rotation of the rotating ejection protrusion 24 and the rotating ejection groove 14, the edges of the rotating ejection protrusion 24 are rounded, and the edges of the rotating ejection protrusion 24 are also rounded.
[0034] Of course, the above are only preferred embodiments of the present invention and are not intended to limit the scope of application of the present invention. Therefore, any equivalent changes made to the principle of the present invention should be included within the protection scope of the present invention.
