A sealing mechanism is suitable for a key device. The key device contains a key base, and the sealing mechanism contains one front ring shell, one lamp base shell and one sealing member. The front ring shell is installed on the key base, and the lamp base shell is installed on the front ring shell. The sealing member contains a sealing body and a sealing wall. The sealing wall is circularly arranged around the sealing body so as to be fixed on the lamp base shell. When the lamp base shell is installed on the front ring shell, the lamp base shell and the front ring shell respectively push the periphery of the sealing body, so that the sealing body and the front ring shell jointly form one sealing space so as to seal one first open groove on the key base.

Sealing mechanism and push-button device

A heart-shaped self-locking button includes one housing and one push rod. The push rod is slidably arranged within the housing. A heart-shaped structure is formed on the push rod. The button includes one pin and one flexible element. One end of the pin is fixed on the housing, while the other end is fitted with the heart-shaped structure. The flexible element is arranged between the housing and the push rod and presses the pin towards the heart-shaped structure to allow the pin to be in constant contact with the heart-shaped structure. The heart-shaped structure is arranged on the push rod. 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.

Heart-shaped self-locking button

A button includes a housing, an operating portion, a mount, a first pushing rod, a bridge, an elastic member, and a second pushing rod. The mount is mounted in the housing. The first pushing rod is movably disposed in the mount. A bump is formed on the first pushing rod. The bridge and the operating portion are disposed on ends of the first pushing rod. The second pushing rod is movably disposed on the bridge and is effected by the elastic member. A step is formed in the housing and is located between the mount and the bridge. The elastic member is disposed on the first pushing rod and is located between the bump and the step. The first pushing rod is slidable relative to the mount under the effect of the operating portion or the elastic member, and drives the bridge and/or the second pushing rod to move.
