Problems solved by technology

At present, pins are mostly used as combined connectors in the connectors of building block toys to combine two different building blocks together, but the existing connecting pins are generally divided into male and female connecting ports with different connecting structures at both ends. , When assembling, it is necessary to identify the combination direction of the connectors to complete the assembly. This design increases the difficulty of assembly. Improper assembly will cause damage to the building block components. Some connection ends have poor bending resistance and are easy to break. , and the male and female connection ports are not expandable after the assembly is completed, and cannot continue to be extended and assembled, which has relatively large limitations. At the same time, the current connection pin structure is relatively complicated. To achieve the purpose of butt joint assembly, it is difficult to open the mold and manufacture, the production cost is high, and the service life is short

Embodiment 1

[0043] When assembling, such as figure 1 As shown, the two connecting pins 4 arranged at an annular interval at any end of the connecting part 1 are aligned with the connecting through holes 21 in the connecting sleeve 2 for insertion and assembly. When the limit band 22 is in contact, it continues to push inward, and the arc transition 61 at the top of the limit protrusion 6 and the surface of the limit band 22 are pressed against each other, so that the through capacity of the connecting pin 4 to the middle of the connecting plate 3 changes. The center of the hole 31 is inclined, and the variable hole 31 provides a deformable area for the connecting pin 4. When the spacer protrusion 6 passes through the spacer band 22 completely, the clamping recess 7 is stuck on the spacer band 22, and a " "click", the limit protrusion 8 is embedded in the combination limit groove 23; in the connection through hole 21, the connection pin 4 of another connection part 1 is aligned with the co...

Embodiment 2

[0046] When assembling, select the connecting part 1 with 3 connecting pins 4 and 3 insertion gaps 5 on the connecting plate 3 and align it with the connecting through hole 21 in the connecting sleeve 2 to insert and assemble. When the front end of the outer wall of the connecting pin 4 When the limit protrusion 6 is in contact with the limit band 22, it continues to push inward, and the arc transition 61 at the top of the limit protrusion 6 is pressed against the surface of the limit band 22, so that the connecting pin 4 moves toward the connecting plate 3. The center of the through variable hole 31 in the middle is inclined, and the variable hole 31 provides a deformable area for the connecting pin 4. When the limiting protrusion 6 completely passes through the limiting band 22, the clamping recess 7 is locked in the limiting position. On the belt 22, a sound of "click" is issued, and the limiting convex plate 8 is embedded in the combined limiting groove 23; in the connectin...

Abstract

The invention relates to the technical field of combined and assembled building block toys, in particular to an assembled building block connecting pin external member which comprises a connecting part and a connecting sleeve, and a connecting plate is arranged in the middle of the connecting part. Connecting pin columns which are equally divided in a circular mode along the central axis, are annularly arranged at intervals, are perpendicular to the connecting plate and have fan-ring-shaped cross sections are arranged on the upper connecting face and the lower connecting face of the connectingplate, an inserting gap is formed between every two connecting pin columns, and limiting protrusions are arranged at the tops of the outer walls of the connecting pin columns. The external member hasthe beneficial effects that the connecting pin columns at the two ends of the connecting part adopt the same symmetrical structural design, the direction does not need to be distinguished during mounting, mounting is convenient, operation is easy and convenient, the newly-designed connecting pin columns are matched with the connecting sleeve, the structure is simple, the machining cost is low, and combination is firm; and meanwhile, the connecting pin columns on the multiple connecting parts are inserted in a staggered mode, infinite extension and assembly can be achieved, the universality ishigh, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of combined building block toys, in particular to a set of connecting pins for assembling building blocks. Background technique [0002] Assembled building block toys are deeply loved by parents and children for their various combinations. Assembled building block toys can not only exercise children's hand-eye coordination, but also help develop children's intelligence, which has a great impact on children's brain creative thinking. Inspiration, through free combination to improve spatial imagination and creativity. [0003] The structure of the existing assembled building block toys mainly adopts the combination mode of splicing different building block parts by connecting parts, and splicing a single building block part into different shapes and structures according to different ideas. At present, pins are mostly used as combined connectors in the connectors of building block toys to combine two different...
