Abstract
The utility model relates to sewing machine component, especially a kind of needle bar sleeve of sewing machine; Comprise body, the wall of described body has oil filler point, there was oil ring the below of described oil filler point, and the described upper surface crossing oil ring has the first groove, has through hole, had oil network in described first groove in described first groove; There is circle second groove described side crossing oil ring, has sealing ring in described second groove.Beneficial effect: lubricating oil is held oil filler point and is injected in body, enters into below body by the through hole crossed in the first groove of oil ring upper surface, lubricate; In the first groove, oil network was installed, can to its filtration of lubricating oil, filter the impurity in lubricating oil, such grease is not easy skewness in crack; And in use also can not there is sintering phenomenon.
Description
Technical field
The utility model relates to sewing machine component, especially a kind of needle bar sleeve of sewing machine.
Background technology
During Sewing machines work, the shank at head position does high frequency motion up and down, and the shank cover that Chang Huiyu is enclosed within its outside rubs; there is sintering phenomenon in easy Yin Gaowen; therefore, people can add lubricating oil, to ensure the smooth and easy work of shank long-term security in the crack between shank and shank cover.But, liquid for injecting.The amount of lubricating oil is difficult to control usually, and when oil mass is few, grease is easy skewness in crack; When oil mass is many, by easily overflowing from crack end, pollute sewing, and straight oilhole makes lubricating oil not easily flow downward.
Chinese patent CN203855795U discloses a kind of needle bar sleeve of sewing machine, comprise body, described body wall has downward-sloping oil filler point, described oil filler point, below were provided with oil ring, and described oil ring lower surface is excessively plane, and upper level reduces from oil filler point one end gradually to the relative other end, cross oil ring circumference and be 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.But, still there is following technical deficiency: the sealing effectiveness of (1) sealing ring is bad, easy leakage of oil; (2) the shank medium-term and long-term residual dregs of fat of cover or the residue not easy-clear after sintering.
Summary of the invention
The technical problems to be solved in the utility model is: overcome technical deficiency of the prior art, provides a kind of good sealing effect of sealing ring, the needle bar sleeve of sewing machine of the residue easy-clear produced after Long-Time Service.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of needle bar sleeve of sewing machine, comprise body, the wall of described body has oil filler point, there was oil ring the below of described oil filler point, and the described upper surface crossing oil ring has the first groove, has through hole, had oil network in described first groove in described first groove; There is circle second groove described side crossing oil ring, has sealing ring in described second groove.
Further, have accumulator in described body, described accumulator, at oil filler point with excessively between oil ring, is separated by dividing plate between described accumulator and mistake oil ring, described dividing plate has oil diverting port.
Further, the outer wall of described accumulator has an eyepiece.
Further, the lower surface of described oil ring is excessively stepped.
Further, there is asphalt felt the lower end of described body.
Advantageous Effects of the present utility model is adopted to be:
(1) lubricating oil being held oil filler point is injected in body, enters into below body, lubricate by the through hole crossed in the first groove of oil ring upper surface; In the first groove, oil network was installed, can to its filtration of lubricating oil, filter the impurity in lubricating oil, such grease is not easy skewness in crack; And in use also can not there is sintering phenomenon.
(2) separated by dividing plate between accumulator and mistake oil ring, described dividing plate has oil diverting port.Adopt this structure, avoid on the one hand due to oil mass many time, by easily overflowing from crack end, pollute the technical deficiency of sewing; On the other hand, can avoid, because volume read-out is few, needing frequent apply oil, use the technical deficiencies such as inconvenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation crossing oil ring of the present utility model;
In figure: 1 is oil filler point, 2 was oil ring, and 3 is the first groove, and 4 is through hole, and 5 is dividing plate, and 6 is the second groove, and 7 is accumulator, and 8 is eyepiece, and 9 is asphalt felt
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, a kind of needle bar sleeve of sewing machine, comprises body, the wall of described body has oil filler point 1, there was oil ring 2 below of described oil filler point 1, and the described upper surface crossing oil ring 2 has the first groove 3, there is through hole 4 in described first groove 3, in described first groove 3, had oil network; There is circle second groove 6 the described side crossing oil ring 2, has sealing ring in described second groove 6.
Operation principle: lubricating oil is injected into body from oil filler point 1, enters into below body by the through hole 4 crossed in the first groove 3 of oil ring 2 upper surface, in the shank interplanting used time, and lubricate; In the first groove 3, oil network was installed, can to its filtration of lubricating oil, filter the impurity in lubricating oil, such grease is not easy skewness in crack; And in use also can not there is sintering phenomenon.
Have accumulator 7 in described body, described accumulator 7, at oil filler point 1 with excessively between oil ring 2, is separated by dividing plate 5 between described accumulator 7 and mistake oil ring 2, described dividing plate 5 has oil diverting port.Adopt this structure, avoid on the one hand due to oil mass many time, by easily overflowing from crack end, pollute the technical deficiency of sewing; On the other hand, can avoid, because volume read-out is few, needing frequent apply oil, use the technical deficiencies such as inconvenient.
The outer wall of described accumulator 7 has an eyepiece 8.Adopt this structure, can the convenient oil mass clearly learnt in body number, convenient operator uses.
The lower surface of described oil ring 2 is excessively stepped.Adopt this structure, convenient lubricating oil flows downward, and constantly can guarantee the lubricity of body interior on the one hand, on the other hand, can gather for a long time by surface lubrication oil, thus is frozen into impurity, affect operation in a place.
There is asphalt felt 9 lower end of described body.Adopt this structure, can siphon away in time body lower end more than grease, prevent further overflow lubricant pollution cloth.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
