2results about How to "Stable life" patented technology

The application belongs to the technical field of mobile charging equipment and relates to a compact charging vehicle body. The vehicle body comprises a frame body integrally welded and formed, which is internally provided with first-layer, second-layer and third-layer battery placing frame structures stacked in sequence from top to bottom. The bottom center of the third-layer battery placing frame structure is provided with a water-cooled cabinet storage frame structure for installing a water-cooling module to realize efficient heat dissipation. The frame body is provided on one side with an integrated energy conversion module placing frame structure for installing functional units. The bottom of the frame body is provided on both sides with fixing frames, and the frame body is connected with a foot pedal structure through a Z-shaped foot pedal connecting frame. The application solves the problems of large size and inconvenient movement of the existing mobile charging vehicle through a multi-layer stacking layout, modular integration and integrated welding structure, has the advantages of compact structure, light self-weight, good heat dissipation performance, convenient operation and maintenance and the like, and significantly improves the space utilization and environmental adaptability.

The utility model provides a long -life high -performance screw tip tap has the coarse handle handle, thin neck and screw tip of coaxial connection as an organic whole, the chip flute made of screw tip is three groove structure, and the chip flute of three groove structure is three equal parts distribution relative to tap center axis, and the chip flute groove shape is two straight lines two circular arc form, and the smooth transition between circular arc, the screw tip still is made with straight flute, and the screw tip tap adopts the high -speed steel material of vacuum heat treatment, cryogenic treatment and passivation treatment to make. The utility model solves how to reach the technical problem of high -efficient tapping processing of high -performance screw tip tap product on numerical control equipment, improves tap life, processing high -efficient, quality is stable, long -lived, is fit for promotion.
