一种电加热式防冻型门把手

Abstract

本实用新型涉及门窗五金技术领域，具体为一种电加热式防冻型门把手。本实用新型，包括门把手本体，门把手本体的内部安装有加热模块，门把手本体的表面设有防冻装置，防冻装置包括两个方形板，两个方形板均与门把手本体的表面固定连接，两个方形板彼此靠近的一侧固定连接有圆杆，圆杆的圆弧面转动连接有防护板，防护板内螺纹插设有螺杆，螺杆的表面固定连接有椭圆板。解决了因传统门把手本体在低温环境下未对钥匙孔进行防护，致使空气中的雨水、雪水及雾气极易进入钥匙孔的内部，在低温条件下，这些水分会在钥匙孔内凝结成冰，进而堵塞钥匙孔，使钥匙难以插入或转动，从而对正常开锁造成阻碍的问题。
