Abstract
The utility model discloses a novel needle rod, which comprises a hollow needle rod handle and a needle rod head connected with the needle rod handle in a threaded manner. A wire hook is sleeved on the needle rod head. The hollow needle rod handle is adopted, lubricating oil is injected in the needle rod handle, when the needle rod vertically moves at high speed, the lubricating oil permeates into the needle rod handle and a sleeve and realizes a lubricating effect, friction between the needle rod and the sleeve when the needle rod moves vertically is reduced, precision and state stability of the needle rod are strengthened, heat generated during friction is reduced, and the service life of a sewing machine is prolonged to the greatest degree.
Description
Technical field:
The utility model relates to the needle bar of sewing machine field, refers in particular to a kind of novel shank.
Background technology:
Needle bar of sewing machine is when reciprocating motion, and its movement velocity is high, produces friction during motion and between sleeve; Lubricated not smooth, can make shank work not steady, influence sewing quality; And the shank continuous operation is generated heat easily, and high temperature sintering takes place, and has had a strong impact on the service life of machine.Therefore, need between needle bar of sewing machine and sleeve, add lubricating oil to address the above problem.
Traditional needle bar of sewing machine structure, its shank are a solid shank, on shank or Sewing machines itself do not possess oil groove or other devices that storage lubricating oil is arranged, this just makes Sewing machines in the trend sleeve, not add lubricating oil; If add lubricating oil with manual type, this mode is very improper.The needle bar of sewing machine high-speed motion whenever just need add lubricating oil at a distance from the short time between shank and sleeve, need from Sewing machines, pull down shank when using manual work to add, and complex operation step is time-consuming, influences production efficiency; And to add lubricants capacity too much unsuitable at every turn, adds too much to be prone to when sewing, cloth polluted, and manually-operated also is difficult to control the addition of lubricating oil.
In order to address the above problem, the utility model proposes a kind of novel shank.
The utility model content:
The purpose of the utility model is to overcome the prior art weak point, and a kind of novel shank is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of novel shank, this shank comprise a hollow shank handle and the shank head that joins with shank handle screw thread, socket one line hook on the described shank head.
Furthermore, in the technique scheme, connect before and after the described shank handle, in shank handle front end, be provided with screw thread, a circular hole is offered in shank handle rear end.
Furthermore, in the technique scheme, described shank head is provided with one and inserts the double-screw bolt that is threaded with the shank handle in the shank handle, and shank crown end offers the pin hole that supplies the cushion embedding.
Furthermore, in the technique scheme, described line rhampotheca is fixed through screw on the shank head between the two.
Furthermore, in the technique scheme, all offer the screw that supplies screw to install on described line hook and the shank head.
Furthermore, in the technique scheme, described shank handle rear end is through wool felt sealing.
Have following beneficial effect behind the utility model employing said structure:
1, the utility model adopts improved shank, and through changing the shank handle into open-core type, a built-in wool felt is to the oilhole place; Shank is high-speed motion up and down; Oil is got on the wool felt, sucked micro lubricating oil in sleeve through the shank motion again, played lubrication; Great like this reduced the friction that shank produces when work, thereby the precision that has guaranteed shank and state is steady.
2, the utility model adopts open-core type shank handle, in the shank handle lubricating oil is housed, and makes that shank is lubricated smooth and easy when high degree of motion, reduces the high temperature that causes because of friction widely, has improved the service life of Sewing machines to a great extent.
Description of drawings:
Fig. 1 is the three-dimensional exploded view of the utility model;
Description of reference numerals:
1 shank head, 11 double-screw bolts, 12 pin holes, 2 shank handles
21 circular holes, 3 line hooks, 4 screws, 5 wool felts
The specific embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
See Fig. 1, a kind of novel shank, this shank comprise a hollow shank handle 2 and the shank head 1 that joins with shank handle 2 screw threads, socket one line hook 3 on the described shank head.
Particularly, described shank handle 2 front and back connect, and in shank handle 2 front ends, are provided with screw thread, and a circular hole 21 is offered in shank handle 2 rear ends.Shank head 1 is provided with one and inserts the double-screw bolt 11 that is threaded with shank handle 2 in the shank handle 2, and shank head 1 top offers the pin hole 12 that supplies the cushion embedding.All offer the screw that supplies screw 4 to install on line hook 3 and the shank head 1.After 1 installation of shank head, line hook 3 is placed on the shank head 1, fixing through screw 4 between the two.Shank handle 2 rear ends are through a wool felt 5 sealings.
The utility model installs shank head 1 and shank handle 2 in use, and line hook 3 is placed on the shank head 1, and is fixing through screw 4.In shank handle 2, inject lubricating oil, behind the injection lubricating oil wool felt 5 is filled in shank handle 2 and seal; The height that injects lubricating oil can have circular hole 21, otherwise lubricating oil will spill from circular hole 21.Pass that line hook 3 inserts in the pin holes 12 to sewing needle and fixing with shank head 1.Be installed on the shank that assembles in the body, particularly, this shank is inserted in the sleeve; When starting body, shank moves up and down in sleeve and forms friction with sleeve wall, and shank is high-speed motion up and down; Under effect of inertia, oil is got on the wool felt 5, be sent to micro lubricating oil in the sleeve through wool felt 5, micro lubricating oil oozes out through circular hole 21;, played shank lubrication like this when moving up and down; Reduced the frictional force that shank produces greatly when work, and lowered fricative high temperature, the precision that has guaranteed shank is steady with state.When lubricating oil uses up, from body, remove shank, add lubricating oil again in the shank handle 2 and get final product.
Certainly; The above is merely an embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
