Connecting piece for toy track and toy track

Abstract

The invention relates to a connector for a toy track and a toy track. The toy track includes a support and a connector for the toy track. The connector for the toy track includes a hose, a first joint and a second joint. The first joint and the second joint are respectively connected to the two ends of the hose and arranged coaxially with the hose, the first joint has an insertion slot, and the second joint has an insertion slot adapted to the insertion slot. a male head, the hose has a first annular outer diameter, the first fitting has a second annular outer diameter, the second fitting has a third annular outer diameter, the first annular outer diameter, The second annular outer diameter and the third annular outer diameter are equal so that the surface of the hose, the surface of the first joint, and the surface of the second joint are all at the same level after the insertion protrusion is inserted into the insertion groove. ring surface. The invention can ensure the smooth sliding of the ball or the flying car on the track.

Description

technical field [0001] The invention relates to the field of children's toys, in particular to a toy track and a connecting piece thereof.

The creative heart of designing the ball or flying car route according to the idea, compared with the simple plug-in building block toys currently on the market, the toy track can stimulate children's creativity and strong inte...

AI Technical Summary

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
