This utility model belongs to the field of helmet technology, and specifically relates to a helmet, including a main body and an outer shell covering the outside of the main body. The main body has an inner cavity. The front side of the outer shell has a first air inlet, and the front side of the main body has a second air inlet communicating with the first air inlet. Air can enter the inner cavity through the first and second air inlets. A support frame is provided at the top of the inner cavity, and a cushioning pad is provided on the support frame. The support frame and / or the cushioning pad can rest against the top of the user's head, thereby forming an airflow channel between the top of the inner cavity and the user's head. The purpose of this utility model is to provide a helmet with a simple structure, good heat dissipation, and good comfort.

The utility model relates to a compression-resistant cable, and relates to the field of cables, the compression-resistant cable comprises a plurality of conductors, a protection layer and a sheath layer, the protection layer wraps the plurality of conductors, the protection layer is provided with a plurality of buffer parts, and the sheath layer wraps the conductors and the plurality of buffer parts. By adding the buffer component between the protection layer and the sheath layer, when the cable is impacted, the buffer component buffers the external pressure, so that the wires in the protection layer are not easy to break, and the pressure resistance of the cable is improved.
