6results about How to "Reduce wear effect" patented technology

The application provides a spring processing bending device, and relates to the technical field of spring processing. The spring processing bending device comprises a first equipment part, a second equipment part and a plurality of bending power mechanisms. A guide mechanism is arranged between the mounting plate and the mounting block. The guide mechanism comprises a guide rail, an oil sealing cabin, a receiving cabin, an end head and a pressure applying piece. The oil sealing cabin is sealed and slides on the guide rail. The receiving cabin is communicated with the oil sealing cabin. The end head is connected to the receiving cabin. The pressure applying piece is fixed to the guide rail and is slidingly connected to the oil sealing cabin. The oil sealing cabin is filled with liquid lubricating oil. Holes are arranged in the oil sealing cabin. Spaces for containing liquid lubricating oil are arranged on the sidewall of the guide rail. The liquid lubricating oil between the oil sealing cabin and the guide rail reduces the contact area between the guide rail and the oil sealing cabin, reduces the friction, reduces the wear between the guide rail and the oil sealing cabin, improves the stability and the service life of the guide rail and the oil sealing cabin.

This utility model relates to the field of transformer technology, and more particularly to a transformer with multi-layer coating. It includes a main body and a recess formed on the main body, with a wear-resistant layer coated inside the recess. Two protective plates (first type) corresponding to the recess are provided on the main body. A moving component is provided on the main body to move the first protective plates. A second protective plate (second type) protecting the recess is placed between the two first protective plates. Uniformly distributed intercepting rods protecting the transformer are integrally connected between the two second protective plates. This utility model protects the transformer by coating the recess with a wear-resistant layer, thereby reducing external wear. The moving component on the main body prevents the wear-resistant layer from being applied, and the reinforcing mechanism locks the position of the first protective plates, enabling the first and second protective plates and the intercepting rods to provide impact protection for the main body, thus protecting the internal components.

This utility model discloses a connector for preventing wire detachment, specifically relating to the field of connector technology. It includes a connector base plate with a connecting groove on one side. A locking pin is fixedly connected to the inner cavity of the connecting groove. A conductive element is provided on one side of the connecting groove. A locking and positioning frame is provided on the side of the connector base plate near the conductive element. Fixing blocks are symmetrically fixedly connected to both sides of the connector base plate. This utility model firstly limits the insertion of plug pins by setting pin grooves, facilitating one-to-one correspondence and connection between the plug pins and one end of the conductive element. The anti-detachment block limits the connected plug, preventing detachment. Furthermore, the first locking hook at one end of the conductive element increases the strength of the connection between the plug pins and the conductive element, preventing detachment and ensuring tight contact between the plug pins and the wire connector pins. This reduces contact resistance, minimizes the effects of oxidation and wear, ensures a stable electrical connection, and improves the reliability of electrical signal transmission.

The utility model provides a concentric water distributor for oilfield water injection, which solves the problems that the traditional eccentric water distributor adopts an eccentric water nozzle structure, the fit clearance between a movable water nozzle and a fixed water nozzle is easily abraded by sand grains, the flow regulation precision is low, the formation pressure is higher than the shaft pressure when injection is stopped, fluid containing silt easily reversely permeates into the water distributor, and the water injection efficiency is low. And a water nozzle or a driving mechanism is blocked. The strip-hole-shaped water outlet hole extending in the vertical direction is formed in the second pipeline and the shell, the opening degree of the water outlet hole is adjusted through the plugging barrel capable of moving vertically, the size of the water outlet hole can be flexibly adjusted according to actual requirements, the precision and efficiency of water injection flow adjustment are improved, the opening degree of the water outlet hole is adjusted through the plugging barrel, and the water injection efficiency is improved. The influence of sand abrasion can be reduced, and accurate flow adjustment is ensured.

The utility model discloses a kind of drawer formula hinge assemblies for cabinet door, including base, the side of base is movably installed with hinge component, hinge component includes first connecting plate, second connecting plate and moving block, two ends of second connecting plate are movably connected with first connecting plate and moving block, the side of moving block is provided with mounting seat, the surface of mounting seat is provided with the sliding groove for assisting moving block to move, moving block is slidably connected inside sliding groove, the width of sliding groove is compatible with the size of moving block.The utility model, by hinge component, can assist cabinet door to open and close operation after structure installation is completed, in opening and closing process, moving block can be moved under cabinet door, along with cabinet door synchronous movement is carried out along with sliding groove under cabinet door, so that cabinet door opening and closing operation can be more smooth, and the sliding slot in mounting seat is only used to assist moving block to move, ensure that the wear and tear influence that component is subjected to is substantially reduced in frequent opening and closing process.

The utility model discloses a kind of tool changing mechanism of vertical machining center with self-locking function, the utility model relates to tool changing mechanism technical field, including base, the center of base upper end is fixed with connecting column, the center position of connecting column side wall is rotatably provided with tool holder;The utility model has the advantages that tool changing mechanism can lock tool, can ensure that tool is always firmly locked in the whole process of tool changing operation and tool holder rotation, eliminates the situation that tool and tool holder are separated, effectively avoids the occurrence of tool dropping accident;Tool changing mechanism can drive the ball below it to roll when tool holder rotates, effectively reduces the friction and abrasion between each component in tool holder rotation process by the rolling effect of ball, significantly prolongs the service life of tool holder and related components, and vibration generated when tool holder rotates can also be absorbed, further weaken the abrasion influence caused by vibration.
