The utility model relates to the technical field of downhole geophysical prospecting, specifically a kind of instrument shock absorption type storage device for downhole geophysical prospecting. Including: storage component, the storage component includes box, lid, storage, shock pad and sealing element, the lid rotationally connected on box, storage is set to the inside of box, shock pad is fixedly connected at the bottom of box, the sealing element is set to the outside of box;Protective component, the protective component is set to the inside of box and lid, and protective component includes buffer, foam pad, magic tape, limiting piece and pull rope, buffer is set to the inside of storage, foam pad is set to the inside of box and lid, magic tape is set to the outside of foam pad, limiting piece and pull rope are all set to the outside of buffer. The utility model can avoid that instrument is extruded harm, utilizes lining bushing and is wrapped with instrument protection, can reduce the impact force from each direction, improves the protection effect to instrument.

The utility model discloses a vehicle-mounted network switch which comprises a switch body and a plurality of Ethernet interfaces arranged on the front side wall of the switch body, an L-shaped positioning block can be fixedly installed on the top of the switch body, one end of the L-shaped positioning block is located on the front side of the Ethernet interfaces, and the other end of the L-shaped positioning block is located on the front side of the Ethernet interfaces. The side, close to the Ethernet interface, of the L-shaped positioning block is fixedly connected with a vertically-arranged rubber pad. An opening is formed in the end of the L-shaped positioning block, the L-shaped positioning block is further provided with an elastic clamping assembly, and the elastic clamping assembly corresponds to the opening in position. According to the utility model, the L-shaped positioning block is arranged at the top of the exchange body, so that the end portion of the L-shaped positioning block abuts against the crystal head inserted into the Ethernet interface, the crystal head can be stably located in the Ethernet interface and is prevented from falling off, the stability of signal transmission is ensured, the rubber pad directly contacts with the crystal head, abrasion is reduced, and the service life of the Ethernet interface is prolonged. And the purposes of buffering and damping are achieved.
