Its advantage lies in: simple structure, convenient to use, the line can avoid the line to slide on the surface at glossy body through on twining the spring behind the concave seam again, and it is more stable to be qualified for the next round of competitions, and the cop latch cover warp forer a short time, solves to warp to arouse the dead problem of cop latch card, the lead wire part is the part of bending the most easily and breaking in the cop latch cover usually, adopts the spring that shirks the formula, and it is convenient to change, need not to change whole cop latch cover after the spring damages, practices thrift the cost, and life prolongs by a wide margin, adopts fixed screw fixed spring, the sound construction.
Description
Technical field
The utility model relates to a kind of Sewing machines manufacturing technology, especially a kind of bobbin case on Sewing machines.
Background technology
Existing a kind of application number is that CN201320624833.6 name is called that the Chinese utility model patent of " bobbin case " discloses a kind of bobbin case, and wire hooks as " L shape ", and wherein the side of L is fixed on described bobbin case, and opposite side is close on bobbin case periphery; It is characterized in that, described in be close to the side that wire on bobbin case periphery hooks, perforate on the bobbin case periphery of its endface position.Namely be fixed on bobbin case by fixing cord is hooked the side curving " L shape ", opposite side be close on bobbin case periphery, prevent the line passed from coming off; On bobbin case periphery, fixing cord hooks the position perforate of end face, makes the interior recessed position of bottom line passing hole, and the smooth and easy fixing cord be close to that do not pierce into hindering hooks below and enters in bottom line groove; When bottom line can stretch out swimmingly from bobbin case, use the employee of Sewing machines just can control the overhang of bottom line according to actual needs, make upper thread can catch bottom line effectively, efficiently avoid the phenomenon of the race empty needle in sewing process.But its shortcoming is, stretch into the lead-in wire of lock core cover easily in bobbin case random slip on the surface, defeated line is stable not, and wire hooks easy bending, fractureing affect bobbin case service life, the improvement so its structure needs.
Prior art is compared, the utility model has the advantage of, structure is simple, easy to use, body is provided with recessed joint, and line is by being wound on spring after recessed joint again, line is avoided to slide on smooth body surface, outlet is more stable, and bobbin case distortion is less, solves the problem of being out of shape and causing peg or spindle stuck; Lead portion is the easiest bending and the part that fractures in bobbin case normally, and adopt the spring of dismountable type, it is convenient to change, and without the need to changing whole bobbin case after spring breaking down, cost-saving, service life significantly extends, and adopts fixed screw fixing spring, sound construction.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of defeated line stabilization for above-mentioned prior art present situation, and lead-in wire bobbin case is not yielding, the bobbin case on Sewing machines of long service life.
The utility model solves the problems of the technologies described above adopted technical scheme: the bobbin case originally on Sewing machines, the body comprising bobbin case and the spring be fixed on for coiling on body, described spring comprises front end in the spiral coil that can enclose wrapping wire line, it is characterized in that: a side of described body is provided with the recessed joint that silk thread can embed actively, the logical linear slit of silk thread on body, the recessed joint that are placed in chamber body extend on the spiral coil of spring at front end, extend to the syringe needle hole be fixed on Sewing machines again.
As improvement, described body can preferably extend the boss that can prevent silk thread from skidding off from recessed joint being arranged in recessed joint position.
Improve, described body preferably can be convexly equipped with and make body more all claim profile more attractive in appearance and the platform level symmetrical with boss on another side centered by spring again.
As improvement, described body is provided with shrinkage pool, described shrinkage pool is arranged on the correspondence position that spring tail end and body fix, the inwall of shrinkage pool is provided with internal thread, and in the lateral location of shrinkage pool, be provided with end face opening and spring wire in spring stage casing can be placed in groove wherein, the tail end of described spring is provided with locating hole, when spring is fixed on body, the tail end of described spring is placed in shrinkage pool, the screw rod of described fixed screw is screwed together through the internal thread in locating hole and shrinkage pool, and described spring dismountable type and body are fixed together.
Improve again, described locating hole can preferably by the spring wire ring of spring tail end around forming.
Improve, the spiral of described spring at front end can be preferably two to three circles again.
As improvement, described Sewing machines comprises embroidery machine, sewing machine, serger.
As improvement, described silk thread comprises braided wire, without spinning.
Compared with prior art, the utility model has the advantage of, body is provided with feed wire and (refers to silk silk, as follows) recessed joint, lead-in wire by being wound on spring after recessed joint again, thus efficiently avoid silk thread and irregularly slides on the surface of body, makes lead-in wire more stable, bobbin case distortion is less, has then fallen bobbin case distortion widely and has caused in peg or spindle the problem going between and be stuck; Also have, the spring of lead portion adopts dismountable type structure to be connected with body, not only structure is simple, easy to use, and without the need to changing whole bobbin case after the more important thing is spring breaking down, as long as change the spring of lead portion, and body still can be used, both provide cost savings like this, the longevity has grown the service life of bobbin case significantly again; Further, adopt fixed screw fixing spring, and become positioning through hole at the spring wire ring of spring afterbody, fixed screw and body are fixed and can not be slided, and make fixing more firm, more stable; Thus further increase the connection fastness of spring and body, also have, so the utility model is a kind of revolutionary improvement, be worthy of popularization.
