Title: HEART-SHAPED SELF-LOCKING BUTTON
Abstract:
A heart-shaped self-locking button (100) comprising one housing (110) and one push rod (120). The push rod (120) is slidably arranged within the housing (110). A heart-shaped structure (1231) is formed on the push rod (120). The button comprises one pin (150) and one flexible element (160). One end of the pin (150) is fixed on the housing (110), while the other end is fitted with the heart-shaped structure (1231). The flexible element (160) is arranged between the housing (110) and the push rod (120) and presses the pin (150) towards the heart-shaped structure (1231) to allow the pin (150) to be in constant contact with the heart-shaped structure (1231). The heart-shaped structure of the heart-shaped self-locking button is arranged on the push rod, thus allowing for a simple mold and lowered costs. Also, the flexible element between the housing and the push rod is utilized to press the pin towards the heart-shaped structure on the push rod to allow the pin to be in constant contact with the heart-shaped structure when moving, thus implementing a self-locking function and an extended mechanical life.
