Abstract
The utility model discloses a special-purpose lubricator fitting with 360 DEG sealing, comprising a connection base which is disposed on a shaft seal gland and is hollow in the middle, a non-return valve disposed in a through hole of the connection base, a connecting sleeve connected to the upper part of the connection base, and a hollow cavity which is disposed on the connecting sleeve for oiling. A cross section of the hollow cavity is trapezoid-shaped. The connection base is connected to the shaft seal gland in a manner of threaded connection, and is connected to the connecting sleeve in a manner of threaded connection. The center of the through hole and the center of the hollow cavity lie in the same line. The special-purpose lubricator fitting with 360 DEG sealing is advantageous in that with the method of screw-in type threaded connection, leakage at the time of high-pressure oiling of the shaft seal can be prevented; a spiral joint adopts a double-thread screw, and thereby mounting and dismounting in an oiling process can be fast, and the whole oiling process can be convenient and easy.
Description
Technical field
The utility model relates to the special-purpose pump nozzle of a kind of 360 degree sealings.
Background technique
Be to utilize the oil nozzle of grease gun that the oil nozzle of last axle envelope is annotated when at present, common hand carries out oiling with grease gun to the axle envelope.The employing plug-in type connects, and this Placement runs into to be easy to produce when high pressure injects leaks, and hand can reach 31Mpa ~ 68Mpa with grease gun oiling pressure, because the oil-feed tank characteristic of axle envelope determines oiling pressure very high.
Summary of the invention
For solving the problems of the technologies described above the special-purpose pump nozzle of 360 degree sealings that the utility model provides a kind of screw-in Placement and oiling not to reveal.
The technical solution of the utility model is the special-purpose pump nozzles of a kind of 360 degree sealings, and it is characterized in that: comprise the connection base that is arranged on the sealed cover, described connection base is hollow shape; Be arranged on the one-way valve that connects in the base plate through holes; The connecting sleeve continuous with being connected base top; Described connecting sleeve is provided with the cavity for oiling.
Further improvement of the utility model, described cavity cross section is trapezoid shaped.Its purpose is, the space of a buffering is arranged when making high pressure when oiling enter.
Further improvement of the utility model, described connection base by thread is connected on the sealed cover.
Further improvement of the utility model, described connection base by thread connects and links to each other with connecting sleeve.
Further improvement of the utility model, the described double thread screw that is threaded to connects.Adopt the double thread screw Placement, purpose is to make connecting sleeve with to be connected the base connection more firm, when the high pressure oiling, and the also situation that can not occur leaking.
Further improvement of the utility model, the center of described through hole and the line of centres of cavity are point-blank.Make oiling more smooth and easy, the oiling time spent is short.
The utility model beneficial effect compared with prior art is: adopt the thread connecting mode of screw-in, the leakage when having solved the oiling of axle envelope high pressure; Spiral interface adopts double thread screw, and installation and removal make whole oiling process convenient succinct rapidly in the oiling process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, connect base; 1-1, through hole; 2, one-way valve, 3, connecting sleeve, 3-1, cavity, 4, the oil gun oil filler pipe.
Embodiment
1 pair of the utility model further specifies by reference to the accompanying drawings:
The special-purpose pump nozzle of 360 degree sealings of the present utility model comprises connecting base 1, one-way valve 2 and connecting sleeve 3.
Connect base 1 and link to each other with the axle sealed cover by at the outer surface that connects base 1 outside thread being set, make that connecting base 1 is fixed on the sealed cover.Connect in the base 1 and be provided with through hole 1-1.One-way valve 2 be installed in the through hole 1-1 and one-way valve 2 near the top of through hole 1-1.Connecting sleeve 3 links to each other with the outside thread that is connected base 1 top by the internal thread that is arranged in the connecting sleeve 3; Connecting sleeve 3 and be connected the screw thread that base 1 connects and adopt the double thread screw that cooperatively interacts to connect adopts the double thread screw Placement, and purpose is to make connecting sleeve 3 with to be connected base 1 connection more firm, when the high pressure oiling, and the also situation that can not occur leaking.Connecting sleeve 3 is provided with the cavity 3-1 of oiling, and the cross section of cavity 3-1 is arranged to trapezoidal.The center of the center of cavity 3-1 and through hole 1-1 is connected to straight line, makes oiling more smooth and easy, and the oiling time spent is short.
When oiling, connecting sleeve 3 is installed on the connection base 1, fixed installation is firmly; Oil gun oil filler pipe 4 is fixedly mounted on the connecting sleeve 3, just can oiling.Its install operation process is simple.When oiling finishes, only need connecting sleeve 3 is sent to open and takes away from connecting base 1 very simple and convenient of its unloading process.
