Gap between bar 30 avoids oil between metalwork part 40 and shank 20 and/or between metalwork part 40 and compression bar 30
Gap flow down.However, nonetheless, oil is still had by the gap, and then occur on shank 20, compression bar 30 leaking
Oil pollutes sewing object.
In consideration of it, the utility model proposes one kind to have in order to avoid there is the phenomenon that oily pollution sewing object leaked
Effect avoids the leakproof oil cap of oil leak.
Utility model content
The main purpose of the utility model is to provide a kind of leakproof oil caps, are internally provided with wick, absorb from upper and lower
The oil that shank, the compression bar of movement splash out, prevents by the pollution of sewing object caused by oil leak.
The secondary objective of the utility model is to provide a kind of leakproof oil cap, and the wick is not contacted with shank, compression bar, because
On this shank and compression bar for moving up and down will not attaching oil, and then not will cause oil leak.
Another of the utility model is designed to provide a kind of leakproof oil cap, by the setting of oil duct, and utilizes tooth
Wheel pump can form the reflux of oil, efficiently avoid accumulation oily in wick, further prevent oil leak.
In order to achieve the above object, the utility model provides a kind of leakproof oil cap, wherein the leakproof oil cap is installed in head
The shank metalwork part of part setting and the lower section of compression bar metalwork part, the leakproof oil cap is in the figure of eight and has
Two hollow-out parts, described two hollow-out parts are therefrom stretched out for shank and compression bar respectively, are provided with wick in the leakproof oil cap.
The leakproof oil cap, wherein the wick is set as not contacting with shank and compression bar.
The leakproof oil cap, wherein the edge of the hollow-out parts is provided with the guiding piece upwardly extended, the guiding piece
And the wick is provided between the inside outer wall of leakproof oil cap.
The leakproof oil cap, wherein one end of the leakproof oil cap is provided with oil duct, and the wick is inserted into the oil
Inside road and oil duct is passed through, the gear pump connection inside the other end and sewing machine of the oil duct far from leakproof oil cap, the tooth
Wheel pump is used to draw the oil in the wick.
The leakproof oil cap, wherein the other end of the oil duct tooth connection wheel pump is lower than the oil duct connecting anti-leak oil
One end of lid.
In conclusion the utility model has the beneficial effects that:
1, in the wick that is internally provided with of leakproof oil cap, absorb the shank from up and down motion, the oil that compression bar splashes out, prevent by
The pollution of sewing object caused by oil leak；
2, the wick is not contacted with shank, compression bar, thus move up and down shank and compression bar on will not attaching oil, in turn
It not will cause oil leak.
3, the setting of oil duct can form the reflux of oil by the effect of gear pump, efficiently avoid oily in wick
Accumulation, further prevent oil leak.
Detailed description of the invention
Hereinafter the utility model will be described in more detail based on the embodiments and with reference to the accompanying drawings.Wherein:
Fig. 1 is the structural schematic diagram of head section in the prior art；
Fig. 2 is the main view of leakproof oil cap according to the present utility model；
Fig. 3 is the perspective view that wick is omitted in leakproof oil cap according to the present utility model；
Fig. 4 is the structural schematic diagram for being mounted with the head section after leakproof oil cap according to the present utility model.
In the accompanying drawings, identical component uses identical appended drawing reference.Attached drawing is not according to actual ratio.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
As shown in figs 2-4, main view, the leakproof oil cap for being respectively leakproof oil cap according to the present utility model are omitted
The structural schematic diagram of the perspective view of wick and the head section being mounted with after leakproof oil cap according to the present utility model.At this
Wen Zhong, "up" and "down" are consistent with diagram direction.
The utility model provides a kind of leakproof oil cap 1, be installed on head section setting shank metalwork part with
And the lower section of compression bar metalwork part (not shown).The leakproof oil cap 1 is in the figure of eight, hollow-out parts 11 that there are two tools,
It is therefrom stretched out for shank 2 and compression bar 3 respectively.
In addition, 11 edge of hollow-out parts of the leakproof oil cap 1 is provided with the guiding piece 12 upwardly extended, the guiding piece 12
And wick 5 is provided between the inside outer wall of leakproof oil cap 1, the wick 5 is for absorbing the shank 2 from up and down motion, pressure
