Specific embodiment
Now in conjunction with attached drawing, the invention will be further described.
Fuel inlet fitting 1 is connect with oil pipe, and connecting column 5 is connect with grease gun 8, and connecting column 5 can be freely rotated, thus convenient
Grease gun 8 rotates, and makes the easy to use of grease gun 8.
Embodiment one
As shown in Figures 1 to 4, a kind of grease gun rotary connecting device, including fuel inlet fitting 1, the center of fuel inlet fitting 1 be equipped with into
Oilhole 11；And swivel, swivel are connect with fuel inlet fitting 1；Swivel includes rotation seat 2, and rotation seat 2, which is equipped with, to be connected
Through-hole 21, fuel inlet fitting 1 is fixed on one end of rotation seat 2, and fuel feed hole 11 is communicated with intercommunicating pore 21；Connecting column 5, connecting column 5
One end be rotatably installed in intercommunicating pore 21, and be located at the other end of rotation seat 2, the center of connecting column 5 is equipped with oil outlet 51, out
Oilhole 51 is communicated with intercommunicating pore 21, and connecting column 5 is equipped with stop collar 52, and stop collar 52 is located in intercommunicating pore 21；Sealing ring 3,
Sealing ring 3 is mounted in intercommunicating pore 21, and one end rotation of connecting column 5 is inserted in sealing ring 3；And fixed ring 7, fixed ring 7 are pacified
Mounted in the other end of rotation seat 2, fixed ring 7 passes through connecting column 5, and fixed ring 7 is for stop collar 52 to be limited in intercommunicating pore 21
Rotation.Fixed ring 7 and connecting column 5 are transition fit, it is necessary to assure connecting column 5 can be freely rotated, and transition fit can guarantee
The axis of connecting column 5 does not deflect, to guarantee effective connection of connecting column 5 Yu sealing ring 3, prevents butter from revealing.
Connecting column 5 is limited in the intercommunicating pore 21 of rotation seat 2 by fixed ring 7 and is rotated by stop collar 52, and sealing ring 3 is used for
The sealing of connecting column 5, prevents butter from leaking.
It further include compression ring 4, compression ring 4 is fixed in intercommunicating pore 21, and between stop collar 52 and sealing ring 3, even
Column 5 is connect across compression ring 4, compression ring 4 is for sealing ring 3 to be limited in intercommunicating pore 21.Compression ring 4 prevents sealing ring 3 along even
The axial float of through-hole 21, to guarantee sealing effect.Compression ring 4 and fixed ring 7 can limit the position of stop collar 52 simultaneously,
5 play of connecting column is prevented, and prevents stop collar 52 from damaging sealing ring 3 by pressure, compression ring 4 being capable of effective protection sealing ring 3.
It further include steel ball 6, steel ball 6 is equipped with multiple, and steel ball 6 is between stop collar 52 and fixed ring 7.Steel ball 6 can subtract
Frictional force between small stop collar 52 and fixed ring 7, becomes rolling friction for sliding friction, keeps the rotation of connecting column 5 smooth, pole
The big flexibility for improving the rotation of grease gun 8.
Since grease gun 8 is to be squeezed out butter by high pressure in use, the inside of rotation seat 2 also has larger
Pressure, the end face of connecting column 5 is also subjected to pressure, stop collar 52 is caused to be pressed in fixed ring 7, since pressure is larger, limit

First 1 one end is equipped with filter hole 12, and filter hole 12 is no less than two, and filter hole 12 is communicated with fuel feed hole 11, the hole of filter hole 12
Diameter is respectively smaller than the aperture of 81 oil outlet of pipette tips and the aperture of fuel feed hole 11.Filter hole 12 is located in oil connection.
The filtering that butter is realized by filter hole 12, since the diameter of filter hole 12 is less than the hole of the oil outlet of pipette tips 81
Diameter, therefore the impurity for blocking pipette tips 81 can be kept off in the end of filter hole 12.
Filter hole 12 realizes the filtering of butter, and pipette tips 81 is avoided to block.
Illustrate that the impurity of the end accumulation of filter hole 12 all blocks filter hole 12 when grease gun 8 blocks, tears open
Lower fuel inlet fitting 1 removes the impurity of 1 end of fuel inlet fitting.Since impurity is located at the end of fuel inlet fitting 1, impurity is
The exposed end in connector, cleaning is very convenient, as long as the impurity of 1 end of fuel inlet fitting is wiped off with tool, cleaning speed
Degree is fast.
Filter hole 12 is no less than two and is able to extend using the time, reduces clearing times.If a filter hole in use
12 blockings, can continue to use there are one filter hole 12；If only one filter hole 12 is easy to happen blocking, influence to make
With needing often to clear up.
Fuel feed hole 11 is relatively large in diameter the conveying speed for not influencing butter, avoids the conveying for influencing the unit time of butter
Amount.
The depth of filter hole 12 is not more than 3mm.The depth of filter hole 12 is easy very much to influence the feeding of butter deeply, leads to rear end
Butter is under feeding.
Generally in 1.6mm or so, the diameter of filter hole 12, which is set as 1.5mm, to be had in the aperture of the pipette tips 81 of grease gun 8
Effect filtering can block the impurity of pipette tips 81, and not influence the conveying of butter.
Specifically, filter hole 12 is arranged around the axis annular array of fuel inlet fitting 1 there are four filter hole 12 sets.And it filters
Hole 12 is communicated with fuel feed hole 11.
