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 discloses a multifunctional fire-fighting monitoring device, which comprises a shell, a wiring hole for wiring is arranged at the upper position of the front end of the shell, and a display screen for displaying time is arranged at the middle position of the front end of the shell. The operation state of the shell is checked through a signal indicator lamp at the right side of the front end, a mounting plate capable of sliding is connected to the inner side of a second sliding way through a sliding groove in a sleeving mode, and the mounting plate slides along the sliding groove in the second sliding way through T-shaped columns at the upper end and the lower end. According to the device, the shell is mounted through the mounting plate, the second sliding way can slide along the sliding groove of the first sliding way through the T-shaped column, and the first sliding way can continuously move towards the outer side through the T-shaped column, so that the maximum moving distance of the mounting plate can be increased, and the mounting plate can find a proper position for mounting; and therefore, the monitoring device can be firmly installed.

A rod and wheel integrated fishing line reel with an extending type line guiding mechanism comprises a line reel body and a line cup, the line cup is rotatably arranged on the line reel body through a main shaft, and the line cup is used for winding a fishing line; the crank is in transmission fit with the wire cup through a transmission assembly; the take-up and pay-off guiding mechanism comprises a driving shaft, a wire guiding seat, a wire guiding ring and a lengthened swing support. The line wheel body at least comprises a line wheel body framework, a front rod connecting part and a side cover. The rear end of the lengthened swing support is connected with the wire seat. The guide part of the fishing line is positioned between the line cup and the line leading ring and forms an inlet-outlet line included angle; an axis connecting line is formed between the axis of the main shaft and the axis of the rocking handle shaft, and a rocking handle operation included angle is formed between the axis connecting line and the axis of the front rod connecting part. Through the arrangement of the lengthened swing support, transmission between the wire guide seat and the wire guide ring can be achieved, the arrangement position of the wire guide ring can be changed, and the wire guide ring can be away from the wire guide seat and the wire cup.

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.
