The utility model relates to the technical field of composite PE pipes, in particular to an antibacterial wear-resistant composite PE pipe which comprises a first PE pipe and a second PE pipe, the first PE pipe and the second PE pipe are distributed in a left-right corresponding mode, and six transverse wear-resistant strips are arranged on the outer surface of each of the first PE pipe and the second PE pipe. A plurality of annular wear-resisting strips are jointly arranged between the outer surfaces of the six transverse wear-resisting strips located on the left portion and between the outer surfaces of the six transverse wear-resisting strips located on the right portion, and a first fixing ring is arranged on the right portion of the outer surface of the second PE pipe. According to the antibacterial wear-resistant composite PE pipe, the first PE pipe body and the second PE pipe body are quickly connected in a sealed mode through clamping of the inserting rods and the inserting holes and matching of the sealing gaskets and the sealing grooves, the connecting structure is stable through the corresponding blocks, the springs and other components, operation is simplified, and the installation difficulty is reduced; through cooperation of a mounting ring limiting column and an antibacterial inner pipe limiting hole, accurate mounting of the filter cartridge is achieved, impurities are stably intercepted, the antibacterial inner pipe is protected, and cleaning and replacement are facilitated through the design of a filter cartridge pull block.

The utility model discloses an electroplating cathode conductive seat, which comprises a seat body, an electroplating cathode, an electroplating cathode and an electroplating cathode, one end of the first main copper bar is arranged at the bottom of the groove; one ends of the two conductive side plates are selectively and symmetrically arranged in the groove in a manner of being close to or far away from each other, and the other ends of the two conductive side plates are connected with a power supply; and the conductive hanger can be inserted between the two conductive side plates and is in contact with the first main copper bar. The utility model has the characteristics that the conductivity is improved and the service life is prolonged.

The application discloses a threshold value adjustable vertical double diffusion metal oxide semiconductor field effect transistor, which comprises a drift region, a body region formed in the drift region from the upper surface of the drift region downwards, a gate oxide layer formed on the upper surfaces of the drift region and the body region, and a PN junction composite polysilicon gate formed on the upper surface of the gate oxide layer and composed of a first type polysilicon and a second type polysilicon, wherein the second type polysilicon covers all surfaces of the first type polysilicon except the bottom, and the vertical projection of the PN junction junction boundary formed by the first type polysilicon and the second type polysilicon is located in the body region in the channel region. When the transistor is turned on, the PN junction composite polysilicon gate is in a reverse bias state, and the threshold voltage is raised by affecting the inversion process of the body region through the junction electric field. The application realizes the raising of the threshold voltage of the device without weakening other performances of the device, and does not change the core gate oxide process and need to cooperate with a groove structure.
