The utility model provides a structure for improving the uniformity of an aluminum target film, which comprises an aluminum target material and a back plate welded with the aluminum target material, and the thickness of the central area of the aluminum target material is larger than that of the edge area of the aluminum target material. The structure reduces penetration of magnetic lines of force in the central area of the target material and reduces the surface magnetic field intensity of the central area of the target material, so that the uniformity of the aluminum target film is effectively improved.

This application relates to an explosion-proof door with good locking effect, comprising a door panel and a door frame. A rotating ring of the door panel is connected to the door frame. A cavity is formed inside the door panel, and a locking assembly is disposed within the cavity. The locking assembly includes four push rods, four connecting rods, a screw, and a rotating sleeve. The four push rods correspond to the four side walls of the door panel and slide along the direction close to or away from the inner side wall of the cavity. The screw is rotatably connected to the cavity, and the rotating sleeve is threadedly connected to the screw. The four connecting rods correspond to the four push rods, with one end rotatably connected to the push rod and the other end rotatably connected to the rotating sleeve. A limiting post is provided on the push rod for passing through the door panel, and a limiting groove is formed on the door frame for engaging the limiting post. When the door panel is locked, the connecting rod and the rotating sleeve are located in the same plane. This application improves the locking effect of the explosion-proof door.

The utility model discloses a portable detector for heavy metal content of agricultural products, including detector body, is set up with the window on the detector body, the window top is provided with the cover of size matching, the inside installation of detector body has the light source and light source detector, the inside of detector body is placed with the colorimetric cup, the colorimetric cup is centrally arranged between the light source and light source detector. A kind of portable detector for heavy metal content of agricultural products of the utility model, in the process of detecting heavy metal content of agricultural products, through the cooperation of installation component, driving assembly, rotating assembly and knocking component, not only make the impurities suspended in sample solution surface in colorimetric cup settle, improve the precision of heavy metal content detection result, also eliminate the hidden trouble of fingerprint and liquid residue that manual shaking colorimetric cup can bring, reduce its influence on the transmission and scattering of light, reduce measurement error.

The utility model discloses an electroplating bath impurity removal device for roller production in the technical field of electroplating baths, which comprises a box body of an electroplating bath, a drain pipe for discharging electroplating liquid is mounted on one side of the box body, and a blow-off pipe for discharging impurities is mounted on the other side of the box body. A filtering part used for blocking impurities in the electroplating solution is installed on the inner side of the box body, a driving part used for driving the filtering part to move is installed on the inner side of the box body, the filtering part can conduct impurity removal and purification on the electroplating solution, and the driving part can drive the filtering part to conduct reciprocating motion in the box body; impurities in the electroplating solution are blocked and filtered by the filtering piece and then discharged through the blow-off pipe, and the filtering piece and the driving piece are disassembled or assembled through the locking piece so that the filtering piece can be replaced conveniently or the filtering piece can be selectively installed according to needs.
