Detailed Implementation

[0022] Example 1, referring to Figures 1-6 A quick-release connection structure for a track toy is disclosed. The track toy is composed of several track modules 10 connected end to end. Adjacent track modules 10 are detachably connected by 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 ​​groove 21 and a rotating mating groove 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 ​​groove 21 can be rotatably engaged and engaged. The rotating ejection part 12 is correspondingly engaged with the rotating mating groove 22, and the rotating ejection part 12 is offset from the rotating mating groove 22 when it rotates.

[0023] 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 mating 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 mating groove 22. 2. The two track modules 10 are staggered and separated from each other, thereby causing the locking part 11 and the locking groove 21 to disengage, thus realizing the rapid separation and disassembly of the two track modules 10. It should be noted that since the two track modules 10 need to rotate relative to each other when disassembling, the locking connection between the locking part 11 of the locking protrusion 1 and the locking groove 21 of the locking groove 2 is rotatable, that is, the two are locked together and fixed in the axial direction, and the two can rotate around their central axis. Therefore, the overall shape of the locking part 11 and the locking groove 21 should be cylindrical.

[0024] 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. Simultaneously, the outer edge of the rotating ejector 12 is provided with an ejection ramp 121. When the locking protrusion 1 and the locking groove 2 are engaged and the locking protrusion 1 rotates, the ejection ramp 121 of the rotating ejector 12 disengages the rotating ejector 12 from the rotating groove 22, thus disengaging the locking part 11 of the locking protrusion 1 from the locking groove 21 of the locking groove 2.

[0025] 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.

[0026] 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.

[0027] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
