Abstract

本实用新型涉及算珠结构改进技术,本算珠由带 珠孔的实心珠体和一个与之相配的孔圈组成。实现 了制作工艺简便、算珠牢度好、算珠重、成本低和算珠 珠孔两头小、中间大的要求。

Description

本实用新型涉及一种算珠结构改进技术。
算珠已从直孔算珠改进为非直孔算珠,目前主要有中国专利90203868.0和90217796.6等几种类形。前一专利由两个阴阳接口的抛物形半珠粘合而成,装配时如不小心,会造成接口处留有沾贴缝隙,而且经不起较重的摔碰;后一专利公开的算珠由外圈和内圈组成,内圈分为两截两头内径尺寸不一的园柱,分别从两边嵌入算珠的外圈,该算珠制作工艺比较繁杂,成本相应提高。
本实用新型的任务是提供一种珠孔中间大、两头小的实芯重型算珠,且制作工艺简便、牢固度好,成本低。
本实用新型包括实芯珠体和珠体上的珠孔,珠体上的珠孔为三道直径依次增大的同心园柱形孔,有一孔圈嵌在珠体的珠孔大端,构成一颗完整的算珠。
为了构成中间大、两头小的珠孔,孔圈的内径与珠体上的珠孔小端相同,孔圈的外径与珠孔大端相配。
本实用新型具有结构简单、制作方便、成本低、算珠牢度好等优点,并可通过改变原料配比来增加算珠的重量,制成的算珠珠孔两头小,中间大,减少算珠与算盘档间的摩擦力,能克服滞珠、漂珠等现象,产生滑而稳之效果。
图1为本实用新型结构示意图;
图2为图1的俯视图。
结合附图作进一步说明:本实用新型由一个带珠孔的实芯珠体1和一个恰好嵌入珠体1一端的孔圈2组成。珠体上的珠孔为三道直径依次增大的同心园柱形孔,孔圈2的内径与珠孔小端相同,其外圈尺寸与珠孔大端相配,孔圈2的厚度要求为嵌入珠孔大端后与珠体1端面平齐。将孔圈2沾上胶粘剂嵌入珠体的珠孔大端,两者形成珠孔两头小、中间大的算珠。珠体上的三个同心园柱形孔,要求两头的园柱高度小,以便形成的珠孔与算盘档之间的接触面减少。本算珠采用合成塑料或胶木等材料,可通过改变原料的配比增加算珠的重量,使制成的实芯算珠达到重型珠的要求。本算珠也可采用木材等制成。
