The universal oil inlet pipe device for the oiling machine comprises nozzles (1), pipe bodies (5), a lock nut (4) and a pipe holder (7), wherein both the number of the nozzles (1) and the number of the pipe bodies (5) are two, with one on the upper part and one on the lower part; one ends of the nozzles are provided with external threads (1.1), and the other ends of the nozzles are provided with light pipes; one ends of the pipe bodies are provided with external threads (5.1); the light pipe ends of the nozzles (1) are inserted into the external thread (5.1) ends of the pipe bodies (5); the end parts at the other ends of the upper pipe body and the lower pipe body (5) are closed, and oil conveying openings (5.1) are arranged aside the pipe bodies; the oil conveying openings (5.1) of the upper pipe body and the lower pipe body (5) are closed by the pipe holder (7) which is longitudinally connected and fixed with the pipe bodies (5) through stay bolts (9); and the lower nozzle, the lower pipe body, the oil conveying opening aside the lower pipe body, a cavity in the pipe holder, the oil conveying opening aside the upper pipe body, the upper pipe body and the upper nozzle form a hermetical oil conveying channel (13) from the bottom to the top, When pipes are arranged on a service station, the universal oil inlet pipe device can simultaneously realize the adjustment of the longitudinal distance, the transverse distance, the longitudinal angle and the transverse angle so as to realize the aim of connecting rigid pipes.

The invention relates to a communication cable connection device and discloses a connection device for correspondingly connecting respective insulated wires in two connected communication cables. Thecommunication cable connection device is characterized in that a fixing cylinder is placed in the middle of the bottom end of a sleeve by a fixing bearing; a sealing sleeve is placed at the bottom ofthe fixing cylinder and is communicated with the fixing cylinder; a fixing ring is placed on the top of the fixing cylinder and is placed in the sleeve; a plurality of limit slots are formed at equalintervals in the fixing ring; a plurality of connecting plates are placed at equal intervals to the outer side of the fixing ring and correspond to the plurality of limit slots respectively; the connecting plates are located in the sleeve and are provided with through holes therein; a plurality of mounting holes are formed in each connecting plate; a fixing plate is placed on each connecting platethrough a plurality of fixing rods; the plurality of fixing rods correspond to the plurality of mounting holes in each corresponding connecting plate respectively; two limiting blocks are respectively placed on each fixing plate and are placed opposite to each other, and two opposite faces on the two limiting blocks form an arc-shaped surface; and the arc-shaped surfaces have a plurality of grooves therein.

The invention discloses a rusting-preventing structure for a household water pipe metal joint. The rusting-preventing structure comprises a water inlet pipe, and a liquid inlet hopper is arranged at the top of a liquid storage tank. A connecting shaft is arranged between the liquid inlet hopper and an upper cover, and a pressing air bag is arranged at one end of a containing box. A filtering plateis arranged inside the containing box, and the outer surface of a sleeve is provided with a corrosion-preventing coating. An internal thread is arranged on the inner wall of the sleeve, and the outersurfaces of a first connecting pipe and a second connecting pipe are provided with external threads correspondingly. According to the rusting-preventing structure, the first connecting pipe and the second connecting pipe can be connected in the sleeve, sealing rings are arranged on the positions, close to the sleeve, of one ends of the first connecting pipe and the second connecting pipe correspondingly, thus by manually pressing the pressing air bag, a rust remover can be extruded into the sleeve through the pressure, the rust remover is extruded to the outer surfaces of the first connectingpipe and the second connecting pipe advantageously, the problem that corrosion rusting caused by surrounding media on the first connecting pipe and the second connecting pipe is effectively solved, and the service life of pipelines is prolonged.

The invention discloses a mechanical connecting part and belongs to the technical field of connecting parts. The mechanical connecting part comprises a buckle cap and a buckle body. The interior of the buckle cap is of a hollow structure, and the bottom of the buckle cap is provided with an opening. Clamping parts are inlaid at the opening.
