CN105673658A 一种变色示温螺丝 无效 - 驳回

一种变色示温螺丝
摘要：
本发明涉及一种变色示温螺丝，包括螺丝本体，在螺丝的螺丝帽上表面涂附有一层示温变色涂料，其中，所述示温变色涂料可以为单变色不可逆示温涂料，或多变色不可逆示温涂料，单变色不可逆示温涂料的变温起始温度为60±5℃，多变色不可逆示温涂料的变温起始温度为60±5℃，变色的温度范围在60±5℃至300±5℃之间。本发明的变色示温螺丝弥补了传统示温方法的不足，对电路接头过热部位一目了然、定位准确，便于高、低压电路接头过热故障的快速发现及处理，可广泛应用于电力、机械、交通、电子等领域。
摘要（英）：

The invention relates to a color-change thermochromic screw comprising a screw body, wherein the upper surface of a screw cap of the screw is coated by a layer of thermochromic coating, the thermochromic coating can be a single-color-change irreversible thermochromic coating or a multi-color-change irreversible thermochromic coating, the initial temperature-change temperature of the single-color-change irreversible thermochromic coating is 60+/-5 DEG C, the initial temperature-change temperature of the multi-color-change irreversible thermochromic coating is 60+/-5 DEG C, and the color-change temperature ranges from 60+/-5 DEG C to 300+/-5 DEG C. By using the color-change thermochromic screw disclosed by the invention, defects of the traditional thermochromic method are made up, overheating parts of circuit connectors are clear at a glance and can be accurately located, and rapid finding and treatment of overheating faults of high/low-voltage circuit connectors can be conveniently realized; and the color-change thermochromic screw can be widely applied to fields such as electric power, machinery, traffics and electronics.
