Abstract

一种双轴铰接式防盗井盖属于路面给排水井或 电缆沟的附件制造领域，其特征在于：它由带有两对 轴孔的双轴铰接环、外周带有一个轴孔的井盖及连接 件组成，该连接件含有一个滑动穿入双轴铰接环的外 侧轴孔中且与井座相连的轴销及一个同时穿入该环 的内侧轴孔和防盗井盖外侧轴孔中的经过铆接的轴 销。它可使防盗井盖打开至100度角，故既可防盗 又保证了维修人员的安全。

Description

一种双轴绞接式防盗井盖属于路面给排水井或电缆沟的附件制造领域。
目前防盗井盖是通过一个插入其外周轴孔和井座内的防盗轴销来起防盗作用的，其缺点是井盖仅能打开在100～120度，无法保证维修人员的安全。
本实用新型的目的在于提供一种井盖可打开180度的使用安全的双轴绞接式防盗井盖。
本实用新型的特征在于：它由带有两对轴孔的双轴绞接环1、外周带有一个轴孔的井盖2及连接件组成，该连接件含有一个滑动穿入双轴绞接环1的外侧轴孔中且与井座相连的轴销及一个同时穿入该环1的内侧轴孔和防盗井盖2外侧轴孔中的经过铆接的轴销。其结构请见附图1～3。
使用证明：该双轴绞接式防盗井盖既可防盗又使用安全。
为了在下面结合实施例对本实用新型作详尽描述，现把本申请文件所使用的附图名称及编号简介如下：
图1：双轴绞接环的纵剖视图；
图2：双轴绞接环的俯视图；
图3：防盗井盖的纵剖视图；
实施例：
请见附图1～3。图3中的3是起井盖孔。当用钩子插入起井盖孔3时，即可打开井盖，由于双轴绞接环1外侧的轴销是滑套于轴孔而其内侧的轴销是铆接固定的，因而可使井盖打开180度，保证了维修人员的安全，而该双轴绞接环1外侧的轴销其两端是插入井座之中的，因而又能防盗。
