Preferably plum blossom shape, certainly with other polygonal shapes also can, such as triangle, pentagon.
As shown in Figure 4, check valve is provided with unidirectional valve pocket 5, described check valve includes valve body 9, and valve body is located at unidirectional
Inside valve pocket, it is connected between valve body 9 and unidirectional valve pocket 5 by screw thread, the oiling passage 10 of up/down perforation is provided with valve body,
Platform 11 is supported provided with spring on the inwall close to oiling channel bottom, ball sealer 12 is provided with oiling channel interior, ball sealer
Bottom is provided with support spring 13, and support spring 13 is supported on spring on platform 11, in the case where being acted on without external force, and ball sealer 12 is in support
The bottom of thimble patchhole 6 is blocked in the presence of spring.
During installation, the filler 1 is arranged on the joint for needing to fill lubricating oil, and the outer surface of body 3 carries external screw thread,
The body of the lower section of annular boss 4 is injected in oil filler point and screwed using screw thread, annular boss 4 is against the outer of oiling bore edges
On wall, for sealing of the increase filler 1 to oil filler point, as shown in Figure 4, the filler body outer wall below annular boss
It is provided with sealing ring 23.Now the bottom lock of thimble patchhole 6 is made filler 1 be hedged off from the outer world by ball sealer 12.To prevent
Dust etc. enters the inside of thimble patchhole 6, as shown in Figure 4, and dust-proof cushion 14 is provided with the top of filler body 3, should
Dust-proof cushion 14 can be made using film for rubber, be provided with otch in the centre of film for rubber, when without external force, suited closing, dust-proof
Pad 14 can prevent the entrance of dust, and when being lubricated oil filling, thimble can be inserted into inside thimble patchhole 6 by otch.Such as
Shown in accompanying drawing 4, dust-proof cushion 14 is clamped by banjo and filler body.
As shown in accompanying drawing 5-7, described oil gun nozzle 2 includes a cylindricality nozzle body, and the upper surface of cylindricality nozzle body is provided with counterbore 15,
Counterbore includes first half counterbore 151 and lower our department's counterbore 152, and the first half counterbore 151 is provided with and the cross section shape of banjo 7
The consistent hole inwall of shape, lower half counterbore 152 is circular port.With reference to shown in accompanying drawing 9, after banjo 7 is aligned with counterbore 15
Banjo 7 may pass through first half counterbore 151 and reach inside lower half counterbore 152, and banjo 7 can be in lower half counterbore 152
Inside freely rotate, after banjo 7 is in 152 inner rotation certain angle of lower half counterbore, the outer wall of banjo 7 with it is upper
The hole inwall of half portion counterbore 151 staggers, and banjo 7 will be unable to be extracted by the inside of counterbore 15, only when banjo 7 goes to it
After the hole inwall of outer wall and first half counterbore 151 is aligned, banjo 7 can just be extracted.
Further, for prevent carry out filling operation when, banjo 7, which turns to the position that can be extracted, causes banjo
7 with the connection failure of filler 1, as shown in Figure 7, the inside of nozzle body counterbore 15 be provided with anti-back locking plate 16, anti-back locking plate 16
Shown in structure as accompanying drawing 8, it carries the through hole 17 consistent with banjo shape of cross section, in the present embodiment, shape of through holes
For plum blossom-shaped, the edge of anti-back locking plate is provided with sliding piece 18, with reference to shown in accompanying drawing 5, is provided with and stirs on the hole wall of nozzle body counterbore
Piece stirs gap 19, sliding piece 18 stretched out by stirring gap 19 and can left and right freely stir.
After above-mentioned design, the initial position of anti-back locking plate 16 is to maintain through hole 17 and aligned with first half counterbore 151, so
Banjo 7 is entered behind the inside of lower half counterbore 152 afterwards, and stirring anti-back locking plate 16 makes the through hole 17 and the first half of anti-back locking plate
Counterbore 151 staggers, and now banjo 7 be will be unable to extract, and filling is finished, and rotates backward anti-back locking plate, makes the logical of anti-back locking plate
Hole 17 is aligned with first half counterbore 151, and now banjo 7 can be extracted.
As shown in Figure 7, the thimble 20 of a up/down perforation is provided with the inside of nozzle body, the thimble 20 is hard cylindrical tube,
The upper surface of nozzle body is stretched out at the top of thimble 20, and thimble bottom stretches out the bottom of nozzle body and is provided with oil connection 21 in thimble bottom.
To prevent the entrance of dust, as shown in accompanying drawing 5 and accompanying drawing 7, dust cap 22 is provided with the top of thimble, can be pulled out when using anti-
Dirt cap 22.
As shown in Figure 9, when being operated, banjo 7 is entered inside the lower half counterbore 152 of nozzle body, and by
It can not be exited to the limitation of anti-back locking plate 16, now the end of thimble 20 pushes downwards ball sealer 12, the quilt of support spring 13
Compression, tube chamber and the insertion of oiling passage 10 of thimble 20 can now carry out pure filling lubricating oil operation, without worrying
The problem of filler 1 is separated with oil gun nozzle 2, check valve is pushed unsuccessfully, lubricating oil will be by successfully by the row of oiling passage 10
Go out, it is therefore prevented that check valve baulk causes the excessive technical problem of lubricating oil.Filling is finished, and anti-back locking plate is stirred, to patching
Head exits oil gun nozzle, and check valve recovers inactive state, and thimble patchhole is closed again.
