Abstract
The invention relates to an angle-adjustable take-up-lever comprising a base provided with positioning holes. A bearing is fixedly arranged at the center of the base, a dial is arranged above the base, a round hole is formed in the center of the dial, the connecting bearing and a take-up-lever body perpendicular to the base are arranged at the center of the round hole, a pointer is fixedly arranged on the take-up-lever body, a positioning lever capable of moving up and down is arranged on the pointer, and the positioning lever performs positioning through thirty six limit holes formed in the base. The limit holes are circularly arrayed in the base on the periphery of the bearing, and a spacing angle among the limit holes is 10 degrees. The angle-adjustable take-up-lever can adjust different angles according to sewing thread toughness and line requirements, sewing threads different in toughness are ensured not to be broken easily in use, and production efficiency is improved.
Description
Technical field
The present invention relates to Sewing machines field, relate in particular to a kind of adjustable-angle thread take-up tension lever.
Background technology
on Sewing machines, in order to make coil unwrapping wire smoothly, and make the sewing thread of emitting be delivered to head, on Sewing machines, be all provided with thread take-up tension lever.Existing thread ran of sewing machine is all fixedly installed on Sewing machines, and its angle is all fixed, because its toughness of different sewing threads is not identical yet, therefore in order to guarantee that sewing thread is in use difficult for broken string, must adjust the angle of thread take-up tension lever.And the angle of existing thread take-up tension lever cannot regulate substantially, therefore in Sewing machines work process, for the bad sewing thread of toughness, easily pull apart.
Summary of the invention
Technical problem to be solved by this invention is that a kind of adjustable-angle thread take-up tension lever that can adapt to different angles demand is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of adjustable-angle thread take-up tension lever, comprise the base that is provided with locating hole, the center of described base is fixedly installed bearing, top is provided with dial, described dial center is provided with circular hole, center of circular hole is provided with connection bearing and the thread take-up tension lever vertical with base, on described thread take-up tension lever, be fixedly installed pointer, on this pointer, be provided with can be up and down backstay, backstay is by being arranged on spacing hole on base location.
Preferably, described spacing hole has 36, and circular array is on the base of bearing surrounding, and the interval angle between spacing hole is 10 degree.
Preferably, described backstay consists of pull bar, spring and gag lever post, and described pull bar connects gag lever post, and pull bar and gag lever post are separately positioned on the both sides up and down of pointer, and spring is positioned on the gag lever post of pointer below, and the bottom of this gag lever post can coordinate with spacing hole.
Compared with prior art, usefulness of the present invention is: this adjustable-angle thread take-up tension lever can need to be realized according to sewing thread toughness and circuit the adjusting of different angles, the sewing thread that guarantees different toughness can in use not be prone to broken string phenomenon, has improved production efficiency.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is adjustable-angle thread take-up tension lever external structure schematic diagram of the present invention;
Fig. 2 is adjustable-angle thread take-up tension lever top view of the present invention;
Fig. 3 is the structure cutaway view of A-A in Fig. 2.
In figure: 1, base; 2, locating hole; 3, thread take-up tension lever; 4, dial; 5, pointer; 6, pull bar; 7, spring; 8, spacing hole; 9, bearing; 10, gag lever post.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of adjustable-angle thread take-up tension lever shown in Fig. 1, comprise the base 1 that is provided with locating hole 2, the center of described base 1 is fixedly installed bearing 9, top is provided with dial 4, described dial 4 centers are provided with circular hole, center of circular hole is provided with connection bearing 9 and the thread take-up tension lever 3 vertical with base 1, on described thread take-up tension lever 3, be fixedly installed pointer 5, on this pointer 5, be provided with can be up and down backstay, described backstay is by pull bar 6, spring 7 and gag lever post 10 form, described pull bar 6 connects gag lever post 10, pull bar 6 and gag lever post 10 are separately positioned on the both sides up and down of pointer 5, and spring 7 is positioned on the gag lever post 10 of pointer 5 belows, the bottom of this gag lever post 10 can coordinate with spacing hole 8, this backstay is located by the spacing hole 8 being arranged on base 1, in order to regulate different angles, described spacing hole 8 has 36, circular array is on the base 1 of bearing 9 surroundings, interval angle between spacing hole 8 is 10 degree.
During use, first by locating hole 2, base 1 is fixed on Sewing machines table, then as required, will on pull bar 6, draws, drive gag lever post 10 upwards, then rotate thread take-up tension lever 3, the pointer 5 on thread take-up tension lever 3 rotates thereupon, and pointer 5 points to after the angle needing, releasing lever 6, gag lever post 10 is bounce-back downwards under the reaction force of spring 7, and gag lever post 10 bottoms coordinate with the spacing hole 8 corresponding with it, makes the thread take-up tension lever 3 can deflection.
This adjustable-angle thread take-up tension lever can need to be realized according to sewing thread toughness and circuit the adjusting of different angles, guarantees that the sewing thread of different toughness can in use not be prone to broken string phenomenon, has improved production efficiency.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
