Connecting piece for toy track and toy track

Abstract

The invention relates to a connecting piece for a toy track and the toy track. The toy track comprises a supporting piece and the connecting piece for the toy track, wherein the connecting piece comprises a hose, a first joint and a second joint, both the first joint and the second joint are respectively connected with the two ends of the hose and are coaxially arranged with the hose, a plugging groove is formed in the first joint, a plugging convex head matched with the plugging groove is arranged on the second joint, the hose has a first circular outer diameter, the first joint has a second circular outer diameter, the second joint has a third circular outer diameter, the first circular outer diameter, and the second circular outer diameter and the third circular outer diameter are equal, so that after the plugging convex head is plugged into the plugging groove, the surface of the hose, the surface of the first joint and the surface of the second joint are on the same circular surface. According to the connecting piece for the toy track and the toy track provided by the invention, the smooth glide of a ball or a coaster on the track can be ensured.

Problems solved by technology

However, since the outer diameters of the first joint 2 and the second joint 3 are not equal to the outer diameter of the hose 1, when the first joint 2, the second joint 3, and the hose 1 are coaxially plugged together, the first joint 2. The outer annular surface of the second joint 3 and the outer annular surface of the hose 1 are on different annular surfaces, which causes the assembled toy track to affect the sliding of the balls, resulting in poor sliding of the balls; and, due to the support 4. Only two semicircular concave holes are provided. Moreover, the part of the body between the semicircular concave hole 42 and the semicircular concave hole 43 is flat. taxiing requirements on the track
