In the built-in presser foot lifting device, described panel inboard has recessed installation cavity two in above-mentioned a kind of Sewing machines, and above-mentioned electromagnet is positioned at installation cavity two places.Installation cavity two is one time punching molded according to the shape of electromagnet, and electromagnet makes the part of electromagnet be positioned at installation cavity two after being installed in the body, matches with installation cavity one, forms the space that electromagnet is installed.
In the built-in presser foot lifting device, installation cavity two outsides of described panel have the projective structure that is complementary with it in above-mentioned a kind of Sewing machines.Installation cavity two is that panel is one time punching molded, and its outside is the projective structure that forms naturally after the punching press.
In the built-in presser foot lifting device, the projective structure of described panel seamlessly transits in above-mentioned a kind of Sewing machines.Naturally form after the panel punching press.
In the built-in presser foot lifting device, the two ends of described electromagnet have installation portion respectively in above-mentioned a kind of Sewing machines, and securing member is positioned at the installation portion place and is connected with body.Securing member is located on the installation portion and with body and is connected mutually, and electromagnet is fixed on the body, and is simple in structure, and Sewing machines is when work, and electromagnet can not rock, good stability.
In the built-in presser foot lifting device, have handwheel on the body of described Sewing machines in above-mentioned a kind of Sewing machines, above-mentioned electromagnet is near the handwheel place.Less near the parts that the internal body at handwheel place is installed, the space is bigger, and electromagnet is installed in this space, place, rationally utilizes the inner space of body, and is reasonable in design.
In the built-in presser foot lifting device, described panel is connected with body by securing member in above-mentioned a kind of Sewing machines.Securing member is located on the panel and with body and is connected mutually, and panel is fixed on the body, and is simple in structure.
Compared with prior art, the electromagnet in the built-in presser foot lifting device has the following advantages in a kind of Sewing machines of providing of the utility model:
1, built-in presser foot lifting device is installed in the inside of body near the handwheel place in this Sewing machines, rationally utilize the bigger characteristic of this place's installing space, and electromagnet is positioned at the inside of body. and the engine body exterior installing space that takies is few.
When 2, built-in presser foot lifting device electromagnet disconnected in this Sewing machines, presser foot lifter was in impaction state, and during electromagnetic actuation, presser foot lifter is in releasing orientation, reduced the working time of the adhesive of electromagnet, long service life.

Among the figure, l, body; 2, electromagnet; 3, panel; 4, iron core; 5, presser foot lifter mechanism; 6, pull bar; 7, installation cavity one; 8, cavity; 9, through hole; 10, installation cavity two; 1l, projective structure; 12, installation portion; 13, handwheel.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Built-in presser foot lifting device is installed in the inside of body l in this Sewing machines, is used for the console presser feet and is in the state that compresses or unclamp.As scheme shown in the l, this presser foot lifting device is built-in, comprises electromagnet 2 and panel 3, and the inside of body l is cavity 8, and sidepiece has the through hole 9 that runs through, and forms recessed installation cavity 1 between through hole 9 and the body l inside.Panel 3 is through punch forming, its medial surface punching press forms recessed installation cavity 2 10, and installation cavity 1 and installation cavity 2 10 are relative and establish, and lateral surface forms the projective structure 11 that the corner seamlessly transits naturally through punching press, have connecting hole on the panel 3, make panel 3 be fixed on the sidepiece of body 1 by bolt.Installation cavity-7 and installation cavity 2 10 are all near handwheel 13 places on the Sewing machines body l, because it is less near the inner parts of installing of the body l at handwheel 13 places, the inner space is bigger, electromagnet 2 parts are positioned at installation cavity 1 and another part is positioned at installation cavity 2 10, the two ends of electromagnet 2 have installation portion 12, by bolt electromagnet 2 is fixed on the body 1, makes the electromagnet 2 can be owing to coming off that reasons such as vibrations cause, good stability.Electromagnet 2 is installed in the inner space that this place rationally utilizes Sewing machines.
Electromagnet 2 links with presser foot lifter by presser foot lifter mechanism 5, its inside has transportable iron core 4, iron core 4 links with pull bar 6, when electromagnet 2 is in off-state, iron core 4 is positioned at the inside of electromagnet 2 and the head place of close Sewing machines, and presser foot lifter is because the structure of Sewing machines itself is in impaction state; When electromagnet 2 was in attracting state, iron core 4 moves to electromagnet 2, and inner the mobile pulling pull bar 6 of iron core 4 was to handwheel 13-side shifting near handwheel 13 places, and pull bar 6 drives on the presser foot lifter and moves, the state that presser foot lifter is in unclamp.Because Sewing machines in use, how a lot of the time that the time ratio that presser foot lifter compresses unclamps is, and this kind setting has been reduced the work of electromagnet 2 adhesives.Time, electromagnet 2 is in the state of disconnection substantially, electromagnet 2 long service life.
Built-in presser foot lifting device is installed in inner cavity 8 places near handwheel 13 of body l in this Sewing machines, has effectively reduced electromagnet 2 required space outerpace is installed, and makes the overall structure of Sewing machines more become reasonable.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as body l, electromagnet 2, panel 3, iron core 4, presser foot lifter mechanism 5, pull bar 6, installation cavity-7, cavity 8, through hole 9, installation cavity 2 10, projective structure 11, installation portion 12, handwheel 13 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
