Long-term use can easily cause the track to deform, the track slope is insufficient, and even form an uphill trend, so that the ball cannot roll all the way down and cannot smoothly run out of the spiral track. Utility Model Content

[0003] The utility model provides a spiral track to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

In adjacent spiral plates, the lower track fence is located below the upper track fence, and the lower track fence is limited by the upper track fence to prevent the lower spiral plate from crossing over the upper spiral plate during use of the spiral track.

[0006] Preferably, the bottom end of the spiral plate is fixedly connected with a discharge track.

[0007] Preferably, the top end of the spiral plate is fixedly connected with a feed track.

[0008] Preferably, the spiral plate and the track fences on both sides thereof form a spiral track groove having a U-shaped cross-section and spiraling downward, wherein the width of the spiral track groove is ≥10 mm, and the depth of the spiral track groove is ≥9 mm.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The device is reasonably designed. By making the rail fence under each adjacent rail be below the rail fence above, the rail can be stably maintained at a sufficient slope to prevent the rail from deforming. Long-term use can ensure that the balls can roll down smoothly.

[0021] Embodiment 1

[0022] See also Figure 1-2 In the embodiment of the utility model,

[0023] A spiral track, comprising a supporting device, a spiral plate 1 is connected to the top of the supporting device, the spiral plate 1 is arranged in a downward spiral shape from the inside to the outside, and track fences 2 are fixedly connected to the edges of the spiral plate 1 on both sides. In adjacent spiral plates 1, the lower track fence 2 is located below the upper track fence 2, and the lower track fence 2 is limited by the upper track fence 2 to prevent the lower spiral plate 1 from crossing the upper spiral plate 1 during the use of the spiral track. The track fences 2 on the edges of the two sides of the spiral plate 1, at least one side of the track fence 2 is installed on the side of the spiral plate 1, rather than being installed and fixed on the top of the spiral plate 1, the outer bottom end of the spiral plate 1 is fixedly connected to a discharge track 3, and the central top end of the spiral plate 1 is fixedly connected to a feed track 4;
