The invention provides a dirty oil blocking device based on marine environmental protection engineering, which relates to the technical field of water cleaning equipment, and aims to solve the problems that an existing marine dirty oil blocking device is mostly a simple floating type blocking form, does not have self-absorbing treating ability, uses other ways to treat after blocking, wastes timeand labor, and causes dirty oil diffusion as a floating type blocking device is easily broken under impact of sea waves or dirty oil overflows. The dirty oil blocking device comprises a blocking module, wherein the left end edge and the right end edge of the front end side wall of the blocking module are fixedly connected to transverse hinged serial-connection mechanisms through fixed bolts separately. The left ends and the right ends of the hinged serial-connection mechanisms are fixedly connected to a front baffle plate at one side through reinforcing hinges, and dirty oil can be blocked bya floating blocker; moreover, dirty oil is gathered to oil inlet tongue plates at left and right sides, so that the dirty oil is conveniently collected and treated.

The invention provides a hollow shaft sealing ring, a hollow shaft, a rotor structure, a motor and an electric automobile, wherein the hollow shaft sealing ring is used for sealing an oil inlet of thehollow shaft, an oil pipe hole is formed in the sealing ring, an oil inlet pipe is arranged in the oil pipe hole, the outer diameter of the oil inlet pipe is R5, the inner diameter of the oil pipe hole is R4, and R4 is larger than R5. According to the semi-closed sealing structure of the hollow shaft, cooling oil can be prevented from leaking along the inner wall of the bushing cavity when the rotor rotates at a high speed while the bushing cavity can be kept communicated with the outside, and the situation that oil cannot be sprayed due to the fact that pressure difference is formed betweenair pressure of the inner cavity and the outside of the oil throwing opening is avoided.

The invention discloses an oil leakage preventing device of a feet dog rack of a sewing machine. The oil leakage preventing device comprises a feet dog rack, a feet dog rack guide rail, an oil baffle and oil seal sheets. The oil seal sheets are assembled in the oil baffle. The feet dog rack slides on the feet dog rack guide rail in a matched mode. The feet dog rack penetrates through the oil seal sheets. The oil leakage preventing device further comprises an inner oil-proof assembly. The feet dog rack guide rail is located on the inner side of the oil baffle. The inner oil-proof assembly is located on the inner side of the feet dog rack guide rail. The feet dog rack penetrates through the inner oil-proof assembly. Two oil-proof measures are arranged on the feet dog rack, and compared with an existing single oil-proof measure, the oil preventing effect is better; the oil seal sheets on the inner oil-proof assembly are designed into a sawtooth shape, and compared with a plane, oil scraping is more thorough and the oil scraping effect is better; through the cooperation with an oil return tank on the feet dog rack guide rail, oil can be recovered; by arranging the two oil seal sheets in the oil baffle, gaps are formed between the oil seal sheets and the oil baffle, oil scraped from the first oil seal sheet can enter the gaps, oil scraping interference between the first oil seal sheet and the second oil seal sheet is avoided, and meanwhile the oil return function can be effectively achieved. The invention belongs to the technical field of oil leakage prevention of the sewing machine.

The invention discloses a miniature ball bushing guide assembly in the technical field of ball bushing.The miniature ball bushing guide assembly comprises a guide column, a guide sleeve, a bushing and a ball, the guide sleeve is provided with an upper annular table and a lower annular table, the upper annular table is provided with an oil storage strip and an oil outlet structure, and the lower annular table is provided with an oil return cavity and a first oil return hole.By moving the pressing table relative to the spring plate, when the pressing table makes contact with the spring plate and presses the spring plate downwards, the spring plate enables the pressing plate to move downwards through the pressing shaft, the oil storage strip is compressed, a part of oil in the oil storage strip is squeezed out, discharged through the oil outlet and falls onto the lining, so that the balls are lubricated, friction and the like between the balls and the guide column are further reduced, redundant oil falls onto the lower annular table, oil enters the oil return cavity to be recycled through the oil return hole, oil waste and the like are avoided, and oil ports and oil plugs can be arranged on the side walls of the oil storage cavity and the oil return cavity so that oil can be conveniently added or discharged.

The invention discloses a welded body open type turnbuckle. The welded body open type turnbuckle is characterized in that a lower fixing screw rod is arranged on the end face of the bottom end of a buckle body, a lower buckle is arranged on the end face of the bottom end of the lower fixing screw rod, an upper fixing screw rod is arranged on the end face of the top end of the buckle body, and a lubricating column is arranged on the outer surface of the upper fixing screw rod; and an upper buckle is arranged on the end face of the top end of the upper fixing screw, a clamping column is arrangedon the end face of the right end of the upper buckle, the lubricating column comprises a column body, an oil filling opening, a fixing plate, a fixing bolt and a connecting groove, and an oil fillingopening is formed in the right side of the end face of the front end of the column body. The end face of the top end of the column body has elasticity and adsorbability, it is guaranteed that the outer surface of the column body is not damaged when the column body is attached to the upper fixing screw rod, and it is guaranteed that external oil can be effectively stored through the adsorbability,and troubles caused by frequent oiling are avoided; and due to the arrangement of the lubricating column, the trouble brought to a user due to the fact that existing equipment is not provided with alubricating device is avoided.

The invention discloses an oil stain isolation device facilitating oil stain collection and used for flat wire production.
