The utility model relates to the technical field of pipettor suction heads, in particular to a high-chemical-resistance low-adsorption suction head with an oil film, which comprises a suction head tube, an oil film layer is arranged on the inner wall of the suction head tube, a fixed joint is fixedly mounted at the top end of the suction head tube, and a guide plugging component is arranged in the suction head tube. The guide plugging assembly comprises an upper set of fixing protruding blocks and a lower set of fixing protruding blocks which are symmetrical to each other and fixedly installed on the inner wall of the suction head pipe, a plurality of guide rods which are annularly arranged at equal intervals are fixedly installed between the upper set of fixing protruding blocks and the lower set of fixing protruding blocks, and rubber pistons are slidably connected to the guide rods, located in the suction head pipe and slidably connected with the suction head pipe. And a plurality of anti-skid convex blocks which are annularly arranged at equal intervals are fixedly mounted on the outer surface of the fixed joint. The protective film has the advantages of being high in chemical resistance, not prone to adhesion and residue protection, and convenient to use.

The utility model provides a pot body assembly and a cooking utensil with the pot body assembly, and the pot body assembly comprises a housing which is provided with a via hole which is communicated with the interior and the exterior of the housing; the mounting frame is arranged in the shell; the trigger structure is movably mounted on the mounting frame, the trigger structure is provided with a trigger head located at the via hole, and the trigger head can be pressed to drive the trigger structure to move; the elastic sealing cap is arranged at the via hole and covers the trigger head, and the elastic sealing cap abuts against the shell through the mounting frame. According to the technical scheme, the problem that water easily flows into the cooker body assembly in the prior art can be effectively solved.

The application discloses a cable connector, which comprises an insulating seat, a first terminal array, a second terminal array, a metal shell and a cable; the insulating seat is provided with a support platform; the first terminal array and the second terminal array each comprise at least one pair of differential signal terminals and ground terminals; the cable comprises a core wire group, and the core wire group comprises signal conductors and ground conductors; wherein a plurality of accommodating grooves are arranged between the first terminal array and the second terminal array; the signal conductors are electrically connected to the differential signal terminals on one side of the support platform; and the ground conductors are bent into one of the accommodating grooves and are electrically connected to the ground terminals on the other side of the support platform. The ground conductors are directly arranged on the lateral sides of the differential signal terminals, thereby improving the electromagnetic shielding effect between two adjacent pairs of differential signal terminals, improving the electromagnetic shielding effect of the first terminal array and the second terminal array, reducing the electromagnetic interference in the signal transmission process, and ensuring the stability of high-frequency signal transmission.

This utility model relates to the field of elevator retrofitting technology in old residential communities, and discloses an elevator column corner protector, including a mounting plate, a guide section, and a corner protector plate; the mounting plate has a cross-shaped cross section with four vertical included angles, one of which is the first included angle, and the vertical included angle diagonally opposite to the first included angle is the second included angle; the guide section is disposed on the outer wall of the two sides of the first included angle, and the guide section includes multiple guide grooves evenly distributed horizontally along the outer wall, and each guide groove is disposed vertically along the outer wall; the corner protector plate includes a connecting plate with a right-angled fan-shaped cross section and an extension plate fixed perpendicularly to the two arc-shaped end faces of the fan; this utility model can vertically guide rainwater falling on the back side of the outer panel by providing multiple guide grooves on the mounting plate, thereby preventing rainwater from flowing horizontally or obliquely into the elevator shaft along the outer panel, effectively avoiding the problem of electrical equipment corrosion caused by rainwater leakage.
