Abstract
The utility model discloses a thread screw-in type cross recess lubricating joint which is mainly formed by a screw, a dowel and a spring, wherein the screw comprises a head portion provided with an injection hole, a rod portion provided with threads and an inner cavity, the dowel and the spring are installed in the inner cavity, one end of the spring is connected with the dowel, and the other end of the spring is connected with the bottom face of the inner cavity. According to the thread screw-in type cross recess lubricating joint, the dowel and the spring are arranged in the screw; when the thread screw-in type cross recess lubricating joint is used, the screw is screwed in basic threads through a cross screwdriver, a lubricating oil injection nozzle is aligned to the dowel to exert pressure to enable a gap to be generated between the dowel and the screw, and therefore lubricating oil is injected by means of the gap. Meanwhile, the dowel compresses the spring to store energy, the injection nozzle is loosened after the lubricating oil is injected, and the spring stretches to jack up the dowel to play a role in sealing. The thread screw-in type cross recess lubricating joint is simple in structure and convenient to use, and meanwhile has the dual functions of common screw type and common steel ball type sealing lubricating joints. Not only can the environment of high-pressure sealing be met, but also production manufacturing difficulty can be reduced.

In order to address the above problem, the utility model provides a kind of formula cross recess lubrication connection that is threaded into.
The utility model is achieved by following technical solution.
A kind ofly be threaded into the lubrication connection of formula cross recess, mainly screw, pin and spring, consist of, described screw comprises the head that is provided with injection orifice, establishes threaded bar section and inner chamber, and wherein pin and spring fitting are in inner chamber, spring one end is connected with pin, and the other end is connected 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 plane with flat section and coordinates.
Described head is countersunk head, tack or coiled hair.
The beneficial effects of the utility model are:
Compared with prior art, the utility model, by screw inside, pin and spring being set, in use, is screwed in the matrix screw thread with Philip's head screw hilt screw, utilize lubricant oil injection nozzle alignment pins exert pressure and make between pin and screw to produce gap, utilize this gap lube oil injection.Pin Compress Spring energy storage simultaneously, charging-up lubricant oil unclamps injection nozzle after finishing, and spring is upheld the jack-up pin and is played seal action.The utility model is simple in structure, easy to use, has the dual functions of plain screw and plain ball formula seal lubrication joint simultaneously.Can meet the environment of high pressure sealing, can reduce manufacturing difficulty again, safety reliability is high, easy to maintenance.
