Description

积木及积木单元 技术领域
本发明涉及玩具领域，具体地说是指一种积木及用于拼接积木的积木单元。
背景技术
幼儿时期是人体大脑成长速度最快时期，而动手能力对婴幼儿大脑的发育具有促进作用。目前，市场上已出现了一些儿童智力玩具，如拼图、魔方以及积木等，而积木由于其可自由拼装及拆卸，深受儿童喜爱。
公布号为CN 103505887A的中国发明专利公开了一种原子积木，积木若干面上有若干接口，根据接口类型将积木分为两类元件，一类为只有凸接口的积木元件，另一类为只有凹接口的积木元件，虽然两类积木元件通过凸凹接口的相互结合实现积木的空间三维拼接，可以搭建出任何形状和结构，但是由于积木具有两种类型，拼装时需要将积木分类，而许多婴幼儿往往无法区别这两类积木，导致其无法进行三维拼接。
授权公告号为CN 203208698U的中国发明专利公开了一种积木，包括基座和连接件，所述基座为六面体，且所述基座的顶面上设置有固定孔，所述基座的底面、左右侧面及前后侧面上均设置有与连接件配设的连接孔。该结构的积木虽然虽然解决了需要对积木进行分类的问题，但积木用于搭建瓶罐，搭建时积木基座需要预留固定孔用于连接瓶罐，因此，基座无法向各个侧面任意延伸，基座延伸具有一定局限性。另外，基座的左右、前后侧面以及底面均只设置一个连接孔，五个面同时连接时容易发生冲突，而使用较短的连接件时，或是连接不牢固，容易发生脱离现象，或是旋入连接孔的深度过深，导致其它连接孔无法连接。
