Abstract
The invention discloses a thread screwing-in type cross groove lubrication joint assembly which is mainly composed of a screw, a pin and a spring, wherein the screw comprises a head part with an injection hole, a rod part with a thread and an inner cavity, and the pin and the spring are installed in the inner cavity; and one end of the spring is connected with the pin, and the other end of the spring is connected with the bottom surface of the inner cavity. As the pin and the spring are arranged in the screw, during use, a cross screwdriver is used to screw the screw in a basal thread, a lubricating oil injection nozzle is utilized to align the pin to apply pressure so that a gap is generated between the pin and the screw, and lubricating oil is injected through the gap. Meanwhile, the pin compresses the spring for storing energy, the injection nozzle is loosened after the lubricating oil injection is finished, and the spring is drawn to jack up the pin to play a sealing role. The thread screwing-in type cross groove lubrication joint assembly has the advantages of simple structure and convenience in use and has the double functions of a common pin and common steel ball type sealing lubrication joints at the same time. The environment of high-pressure sealing can be met, and the manufacturing difficulty can also be reduced.

Technical field
The present invention relates to a kind of assembly that is fastenedly connected, particularly relate to a kind of formula cross recess lubrication connection assembly that is threaded into.
Background technique
As everyone knows, in Course Exercise in Machinery Elements Design, high performance fastening piece is very expensive.In the lubrication connection field, what generally adopt at present is the steel ball type sealing, is that sealing load is too small yet steel ball type seals existing deficiency, and easily leakage or steel ball are deviate from.When particularly using in the high speed such as aircraft, the rocket aircraft, the steel ball of steel ball type sealing is easily deviate from, and aircraft is existed do not have definite potential safety hazard, and safety reliability reduces greatly.Therefore at the mechanical field that needs the high pressure sealing, need again the mechanical space of lube oil injection simultaneously, the steel ball type sealing then is difficult to satisfy its usage requirement.Connect when some mechanical connection has both needed bolt, when needing charging-up lubricant oil again, common lubrication connection then can't be finished this kind function, and simultaneously existing lubrication connection mostly without dismantling groove and being threaded, is dismantled and install very inconvenient.
Summary of the invention
In order to address the above problem, the invention provides a kind of formula cross recess lubrication connection assembly that is threaded into.
The present invention is achieved by following technical solution.
A kind of formula cross recess lubrication connection assembly that is threaded into, mainly formed by screw, pin and spring, described screw comprises the head that is provided with injection orifice, establishes threaded bar section and inner chamber, wherein pin and spring fitting are in inner chamber, spring one end links to each other with pin, and the other end links to each other with the bottom surface of inner chamber.
Described head is provided with cross recess.
Described inner chamber something or somebody to fall back on section one end is provided with sealed wall A.
The bottom of described screw is provided with port.
Described pin is formed a whole by bucking ladder, sealed wall B, support platform and guide table.
Described sealed wall B matches with the sealed wall A of inner chamber.
Described sealed wall B is face with the sealed wall A of inner chamber and contacts.
Described both ends of the spring is respectively equipped with the flat section that the bottom surface with the end face of guide table and inner chamber is complementary.
The end face of described guide table is the plane with flat section and cooperates.
Described head is countersunk head, tack or coiled hair.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention in use, is screwed in the matrix screw thread with Philip's head screw hilt screw by in screw inside pin and spring being set, utilize lubricant oil injection nozzle alignment pins to exert pressure and make to produce the gap between pin and the screw, utilize this gap lube oil injection.Simultaneously pin Compress Spring energy storage, charging-up lubricant oil unclamps injection nozzle after finishing, and spring is upheld the jack-up pin and is played seal action.The present invention is simple in structure, and is easy to use, has simultaneously the dual functions of plain screw and plain ball formula seal lubrication joint.Can satisfy the environment of high pressure sealing, can reduce manufacturing difficulty again, safety reliability is high, and is easy to maintenance.
