Abstract
The invention relates to a height adjustable take-up lever which is provided with a base. A cavity is arranged in the base, a take-up lever body is arranged in the cavity, a rack is arranged on one side of the take-up lever body, the opposite other side of the take-up lever body is provided with a guiding block, the guiding block is matched with a guiding groove arranged on the side of the base in a sliding mode, the rack is meshed with a gear arranged in the cavity, the gear is fixed in the base through a hinge pin, one end of the hinge pin extends out of the base, and a rotary knob is arranged at the extending end. The bottom of the base is provided with a positioning hole. The height adjustable take-up lever can be freely adjusted in height, is firm in structure, ensures that a sewing thread does not break in the using process, and accordingly improves the production efficiency.
Description
Technical field
The present invention relates to Sewing machines field, relate in particular to a kind of adjustable height 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, and if the length of thread take-up tension lever determines tensile elongation and the line-spacing of sewing thread easily to make sewing thread pull apart highly not in place.Thread take-up tension lever length on general Sewing machines is all fixed, therefore for the poor sewing thread of line matter, easily causes its broken string, therefore processing, and production efficiency is reduced.
Summary of the invention
Technical problem to be solved by this invention is, a kind of adjustable height thread take-up tension lever that can free adjustment height 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 height thread take-up tension lever, there is base, in described base, be provided with cavity, in cavity, be provided with thread take-up tension lever, described thread take-up tension lever one side is provided with tooth bar, corresponding opposite side is provided with guide pad, described guide pad is slidably matched with the gathering sill that is arranged on pedestal side, described tooth bar and the gear engagement being arranged in cavity, described gear is fixed in base by bearing pin, and bearing pin one end extends in outside base, and is provided with knob on this elongated end.
Preferably, described base bottom is provided with locating hole.
Compared with prior art, usefulness of the present invention is: this adjustable height thread take-up tension lever can free adjustment height, and sound construction, guarantees that sewing thread is in use difficult for broken string, thereby has improved production efficiency.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is adjustable height thread take-up tension lever external structure schematic diagram of the present invention;
Fig. 2 is adjustable height thread take-up tension lever internal structure cutaway view of the present invention.
In figure: 1, pedestal; 2, thread take-up tension lever; 3, locating hole; 4, gathering sill; 5, guide pad; 6, bearing pin; 7, knob; 8, cavity; 9, tooth bar; 10, gear.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of adjustable height thread take-up tension lever shown in Fig. 1 and Fig. 2, there is base 1, in described base 1, be provided with cavity 8, in cavity 8, be provided with thread take-up tension lever 2, described thread take-up tension lever 2 one sides are provided with tooth bar 9, corresponding opposite side is provided with guide pad 5, described guide pad 5 is slidably matched with the gathering sill 4 that is arranged on pedestal 1 side, tooth bar 9 and gear 10 engagements that are arranged in cavity 8, described gear 10 is fixed in base 1 by bearing pin 6, bearing pin 6 one end extend in outside base 1, and on this elongated end, be provided with knob 7, in order to facilitate the installation of pedestal 1, described base 1 bottom is provided with locating hole 3.
During use, pedestal 1 is fixed on Sewing machines table, then as requested, rotation knob 8, knob 8 rotates by bearing pin 6 driven gears 10, and gear 10 band carry-over bars 9 move up and down, thereby regulate the height of thread take-up tension lever 2.
This adjustable height thread take-up tension lever can free adjustment height, and sound construction, guarantees that sewing thread is in use difficult for broken string, thereby 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.
