Abstract: Disclosed is a chemical oxygen self-rescue device, including a breathing assembly (1), an oxygen generating assembly (2) and a gas bag; (3) the oxygen generating assembly includes an oxygen generating agent tank (21), a gas discharge valve (23) and an oxygen candle (22); the gas discharge valve is arranged on a component above an oxygen generating agent (213) in the oxygen generating agent tank and below a breathing end of the breathing assembly, and the opening and closing of the gas discharge valve are controlled by means of an inflated volume of the gas bag. The chemical oxygen self-rescue device reduces the resistance to breathing, lowers the temperature of breathed gas and improves the utilization rate of the oxygen generating agent.

Abstract: A combination includes a lock body, a shackle having a second leg and a first leg, a lock member provided rotatably within the lock body and a locking element disposed movably within the lock body and provided with the lock member, wherein the first locking element is adapted to be driven by the lock member to do a reciprocating motion between a shackle locking state and a shackle releasing state, wherein when the shackle is at the shackle locking state, the first locking element is driven to engage with the first leg of the shack so as to hold the first leg within the lock body; when the shackle is at the shackle unlocking state, the first locking element is driven to leave from the first leg of the shack so as to enable the first leg to separate from the lock body.

Abstract: A light-emitting diode (LED) lighting apparatus includes a transparent flexible tape with a first transparent pattern and a second transparent pattern, the first transparent pattern being insulated from the second transparent pattern. A plurality of light-emitting diodes is electrically connected with the first transparent pattern. The LED lighting apparatus can also form the first transparent pattern and the second transparent pattern on two sides of the transparent flexible tape, or, furthermore, to form the first transparent pattern and the second transparent pattern stack to generate a multi-story LED lighting apparatus. Such a plane of emitting diode is applied to various display, furniture decoration and lighting.
