The invention provides a crankshaft polishing support device with a self-cleaning function, which comprises an upper support transverse plate, a support column, a lower support transverse plate, a mobile wheel, a fixed through hole, a clampable crankshaft fixed clamping seat structure, a filter adsorption scrap cleaning cover structure, a crankshaft grinding and trimming rod structure, a fixable oil pot air cylinder push rod ejector rod structure, a rear part protective baffle, amanual pushing handle, an anti-skid sleeve, a lifting control switch, a cleaning and dust collecting control switch,a first fixingseat, a lifting air cylinder, a movablesliding groove, a second fixing seat, and a magnet strip. According to the crankshaft polishing support device with the self-cleaning function,thearrangement of a waste collection box, a fixed inserting tube, a manual holding handle, a connecting rod, afile plate, a stainless steel bending strip, and abrush cleaning device are favorable for cleaning the bending portion of the crankshaft after the polishing is completed, the waste collection box is used for collecting, a good working environment is maintained while an unsuitable part is ground and trimmed with the file plate.

The invention provides a device for measuring the spring stiffness coefficient. The device includes a protective supporting shell, a limiting supporting frame structure with a scale line, a stiffnesscoefficient measurement spring structure, test balls, a plastic indicator plate, a convenient-to-carry protective cover structure capable of marking, a foldable protective supporting base structure, an anti-falling stop block, a clamping hole and a fluorescent pasting strip, and the limiting supporting frame structure with the scale line is fixed on the front surface of the protective supporting shell. According to the device for measuring the spring stiffness coefficient, through arrangement of limiting screws and an adjusting handle, the grasped adjusting handle is twisted advantageously, the distance between the limiting screws is adjusted, and the need of placement of test balls with different diameters is met; through arrangement of a protective cover plate, a portable grab handle anda tightly propping bolt, the measuring device is carried by the grasped portable grab handle advantageously, and the convenience and rapidity of use are increased; and through arrangement of a rotating shaft, a fixing sleeve, a protective baffle and a fixing clamping column, the action of shielding protection can be achieved from the front advantageously, and the test balls are prevented from falling.

The invention discloses an intelligent petrochemical fire extinguishing equipment system, comprising a first fixing plate and a motor, wherein the motor is fixedly installed on the lower surface of the left end of the first fixing plate. In the closed space enclosed by the second fixed plate, the third fixed plate and the two protective plates, the fire water gun can be stored and supported to reduce the physical consumption of firefighters due to long-term spraying. By setting protective plates on both sides of the fire water gun, the transmission During the upward movement of the board, it can drive the two protective boards on both sides to move upward synchronously. The protective board can be made of transparent fireproof and high temperature resistant material, which can be used as a protective shield to shield and protect firefighters, and is convenient for fire fighting. Personnel observe the fire situation, and by setting a buffer structure at the bottom of the shock-absorbing plate, the buffer structure buffers the reaction force of the fire water gun, which greatly reduces the impact on the firefighters and effectively protects the personal safety of the firefighters.

The invention discloses a firm automobile water tank support which comprises a fixed mounting plate, a mounting inner plate is arranged on the inner side of the fixed mounting plate, reinforcing ribsare fixedly mounted on the front surface of the mounting inner plate, and a plurality of water tank mounting holes are formed in the positions, located above the reinforcing ribs, of the inner side ofthe mounting inner plate. Mounting fixing plates are arranged on the outer surfaces of the two sides of the fixed mounting plate, fixed inner plates are fixedly mounted on the inner sides of the mounting fixing plates, and two mounting bolt heads are fixedly mounted on the inner sides of the fixed inner plate. According to the firm automobile water tank support, when the automobile water tank support is installed and used, the automobile water tank support can be integrally reinforced, an automobile water tank can be installed and used more firmly, the effect of shielding and protecting the automobile water tank is achieved, damage to the automobile water tank is reduced. When the automobile water tank support is installed and used, the overall impact resistance effect of the automobile water tank support is improved.

The invention discloses a stainless steel-resin composite. The composite comprises a stainless steel substrate (1), an aluminum film layer (3), a anode oxide film (4) and a resin layer (5), wherein the aluminum film layer (3) is disposed on at least partial surface of the stainless steel substrate (1); and the anode oxide film (4) and the resin layer (5) are laminated on the aluminum film layer (3) in sequence. The invention also provides a preparation method of the stainless steel-resin composite. The stainless steel-resin composite provided by the invention has a strong binding force between the stainless steel substrate and the resin layer. The method provided by the invention is environment-friendly. The preparation process is simple. The method provided by the invention can be universally applied on metals such as the stainless steel with relatively stable properties, and can compound the metal and the resin on metals with complex structures.
