Building block track group

Abstract

The invention discloses a cordwood rail group, comprising more than two opened rails and more than one rail connectors. The opened rails are respectively provided with two arc convex surfaces which are arranged on the top surface and are defined by a groove channel and at least two supporting and embedded columns which are arranged at the two ends thereof. The rail connector is provided with the two arc convex surfaces which are arranged on the top surface and are defined by the groove channel and at least two embedded holes which are arranged at the two ends and are respectively embedded with embedded columns of the adjacent opened rails. Therefore, the adjacent opened rails passes through the rail connectors and are embedded into one body under the condition without special joint direction.

Description

technical field [0001] The invention relates to a building block track set, in particular to a building block track set that can be assembled arbitrarily. Background technique [0002] Referring to Fig. 1 and Fig. 2, there is an existing train toy, which mainly includes a track set 1 and a train set 2. The track set 1 has a plurality of tracks 11 interlocked with each other. Each track 11 has a protrusion 111 at one end and a groove 112 at the other end. The train set 2 has a locomotive 21 and a plurality of carriages 22 connected to the locomotive 21 . The headstock 21 and the carriage 22 respectively have two rotatable wheel shafts 211 , 221 , and four wheels 212 , 222 fixedly connected to the wheel shafts 211 , 221 and rolling on the track set 1 . Thereby, the track 11 forms a loop by engaging the protrusion 111 with the groove 112 of the adjacent track 11 , so that the train set 2 slides along the track set 1 with the wheels 212 , 222 . [0003] 1. Since the adjacent...

[0004] 2. Although the train set 2 can slide by the wheels 212, 222, the smoothness and speed of the train set 2 sliding on the track set 1 often depends on the quality of the axles 211, 221 and the wheels 212, 222 , and the assembly relationship of related structures during assembly, there are some deficiencies such as complex structure, difficult assembly, and sliding smoothness not as expected

[0005] 3. Moreover, the train set 2 or the common rail train set on the market often loses the purpose of entertaining because it focuses on the effect of play. Therefore, it imitates the real vehicle in appearance, but ignores the teaching Children's understanding of basic geometric shapes, weight, and the concept of speed
