Abstract
The utility model discloses a sewing machine needle bar sleeve comprising a body. The wall of the body is provided with an oil injection hole inclining down. An oil passing ring is disposed below the oil injection hole. The lower surface of the oil passing ring is a plane. The height of the upper surface of the oil passing ring gradually decreases from one end of the oil injection hole to the other end thereof. The oil passing ring is peripherally provided with a plurality of through holes at intervals; the inner ring surface of the oil passing ring is peripherally provided with a protrusion; a seal ring is disposed between the oil passing ring and the inner wall of the body; oil-absorbing cotton is disposed at the lower end of the body. The oil injection hole is inclined down, a good flow surface is provided for lubricating grease, and the lubricating grease can flow into a gap between a needle bar and the needle bar sleeve; the oil passing ring with the upper surface inclined allows the lubricating grease to be evenly distributed; the oil-absorbing cotton is disposed at the lower end of the body and can absorb excess lubricating grease, and the lubricating grease is prevented from overflowing to contaminate sewing material.
Description
Technical field
The utility model relates to a kind of Sewing machines parts, especially a kind of needle bar sleeve of sewing machine.
Background technology
In Sewing machines when work,, the shank at head position does high frequency motion up and down, and is placed on its outside shank cover friction, easily Yin Gaowen and sintering phenomenon occurs.Therefore, people are to adding lubricant grease in the crack between shank and shank cover, to ensure the smooth and easy work of shank long-term security.But for the amount more difficult control conventionally of injecting liquid lubricant grease, when oil mass is few, grease is easy skewness in crack; When oil mass is many, easily overflow from crack end again, pollute sewing, and straight oil filler point makes grease be difficult for flowing downward.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide under a kind of grease easy to lubricate ooze, distribution of oil mass evenly, the needle bar sleeve of sewing machine that is difficult for overflowing.
For achieving the above object, the technical solution of the utility model is: a kind of needle bar sleeve of sewing machine, comprise body, on described body wall, have downward-sloping oil filler point, described oil filler point below was provided with oil ring, described oil ring lower surface is excessively plane, upper level reduces to the relative other end gradually from oil filler point one end, cross oil ring and be circumferentially interval with some through holes, cross oil ring inner ring surface periphery and upwards form boss, cross between oil ring and inner body wall and be provided with sealing ring, described body lower end is provided with oil absorbent material.
Described oil absorbent material is circular, and the internal radius of oil absorbent material is greater than shank diameter and is less than body internal diameter.
Described inner body wall is positioned at oil filler point below stepped plane, and described oil ring excessively and sealing ring are located in stepped plane.
The beneficial effects of the utility model are: downward-sloping by oil filler point is arranged to, and for lubricant grease provides good flow surface, be conducive to grease and infiltrate in the crack between shank and shank cover; The oil ring excessively tilting by upper surface, is easy to being uniformly distributed of grease; Being arranged so that of sealing ring is unlikely and down permeates fast and cause waste from crossing the grease that overflows of oil ring periphery; Establish oil absorbent material in body lower end, can absorb unnecessary grease, prevent from overflowing pollution sewing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of crossing oil ring of the present utility model.
In figure: body 1, oil filler point 2, mistake oil ring 3, sealing ring 4, oil absorbent material 5, stepped plane 6, through hole 7, boss 8, funnel-form sidewall 9.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of needle bar sleeve of sewing machine, comprise body 1, on described body 1 wall, have downward-sloping oil filler point 2, described oil filler point 2 belows were provided with oil ring 3, described oil ring 3 lower surfaces are excessively plane, upper level reduces to the relative other end gradually from oil filler point 2 one end, cross oil ring 3 and be circumferentially interval with some through holes 7, cross oil ring 3 inner ring surface peripheries and upwards form boss 8, cross between oil ring 3 and body 1 inwall and be provided with sealing ring 4, described body 1 lower end is provided with oil absorbent material 5.
Described oil absorbent material 5 is circular, and the internal radius of oil absorbent material 5 is greater than shank diameter and is less than body 1 internal diameter.
Described body 1 inwall is positioned at oil filler point 2 belows stepped plane 6, and described oil ring 3 excessively and sealing ring 4 are located in stepped plane 6.
When lubricant grease injects from oil filler point 2, because oil filler point 2 is arranged to downward-sloping, for lubricant grease provides good flow surface, being conducive to grease infiltrates in the crack between shank and shank cover, after entering, dropped on grease on oil ring 3, reduce gradually to the relative other end from oil filler point 2 one end because crossing oil ring 3 upper level, make grease flow to low one end from high one end, cross oil ring 3 inner ring surface peripheries and upwards form boss 8, grease can not flowed away from inner ring surface, being arranged so that when oil ring 3 is installed of sealing ring 4 is more convenient, make to be unlikely and down to permeate fast and cause waste from crossing the grease that overflows of oil ring 3 peripheries simultaneously, grease after crossing through hole 7 oil ring 3 and flowing out through funnel-form sidewall 9 uniform-flows the inwall to body 1 surrounding, make the interior oil mass of crack of shank and shank inner room moderate, be evenly distributed, establish oil absorbent material 5 in body 1 lower end simultaneously, can absorb unnecessary grease, prevent from overflowing pollution sewing.
