More Information
Summary:The utility model discloses a fastener is from dynamic testing temperature alarm device. The device is including the fastener body, be equipped with the storage tank on the fastener body, be equipped with alarm device in the storage tank, alarm device includes indicator, elastic component and bush, the bush sets up in the storage tank, the bush with be interference fit between the storage tank, indicator sets up in the bush, and with the bush is laminated mutually, the elastic component is established by the pressure between the tank bottom of indicator bottom and storage tank. This device mainly utilizes the thermal expansion coefficient of bush material to be greater than the thermal expansion coefficient's of indicator material characteristic, realizes the different states that indicator locked when fastener normal atmospheric temperature, popped out when the fastener exceeds predetermined temperature value. The utility model provides a fastener is from dynamic testing temperature alarm device that compact
