Background technology
Electromagnet is widely used on the Sewing machines, refunds on seam mechanism and the cutting facility especially for use in computer controlled sewing machine, and generally this class electromagnet all is mounted in the top of oil groove, and lubricating oil can make electromagnet partly be immersed in the lubricating oil more for a long time in oil groove.
As everyone knows, need coupled power line that it is switched on during work of electromagnet, and the power line access port on the existing electromagnet all is out in the Lower Half of electromagnet.This just makes the access port of power line be immersed in the lubricating oil regularly.Though the surface of most power line all adopts rubber or plastic material to make, anti-corrosive properties are good.But a spot of lubricating oil can be penetrated into the inside of electromagnet along the slit of power line and electromagnet access port, causes the aging of electromagnet inside.And, the lubricating oil of alkalescence also can be penetrated into power line inside in the junction of inside from power line and electromagnet, and can slowly flow to the other end of power line, just electric cabinet place along the copper wire of power line, cause the electric cabinet short circuit or burn, thereby have influence on the work of whole Sewing machines.
Summary of the invention
The purpose of this utility model is the existing the problems referred to above of electromagnet that are used on the Sewing machines at existing, and has proposed a kind ofly can prevent effectively that lubricating oil from flowing backward to the electromagnet at Sewing machines electric cabinet place.
The purpose of this utility model can realize by following technical proposal: a kind of electromagnet that is used on the Sewing machines, comprise a body, be respectively equipped with iron core and installing plate in the both sides of body, described iron core passes body, described installing plate is connected on the body, by this installing plate body is fixed in the top of Sewing machines oil groove, it is characterized in that, described electromagnet also comprises a power line that feeds body, and the access port of power line is in the first half position of this side of installing plate.
Installing plate and body are connected, and body is fixed in the top of Sewing machines oil groove by this installing plate, and the body access port that inserts power line is in the first half position of this side of installing plate, make the access port of power line can not be immersed in the lubricating oil in the oil groove.Electromagnet energising back iron core can be realized freely stretching in body.
At the above-mentioned electromagnet that is used on the Sewing machines, have on the described installing plate and the corresponding through hole in power line access port position.Installing plate covers on the access port of power line, therefore has a through hole with corresponding place, power line access port position on installing plate, and power line is linked in the electromagnet ontology smoothly.
At the above-mentioned electromagnet that is used on the Sewing machines, described installing plate is inverted "L" shaped, forms with the right angle form by two stationary planes.One of two stationary plane is connected with electromagnet, and another face is fixed on the top of Sewing machines oil groove, and two stationary planes are fixed together with the right angle form again, and electromagnet is fixed on the top of Sewing machines oil groove the most at last.
At the above-mentioned electromagnet that is used on the Sewing machines, have several fixing holes on the vertical fixing face of described installing plate, between installing plate and the electromagnet by being threaded.By being threaded, installing plate and electromagnet dismounting can be come convenient the cleaning and installation when needing between installing plate and the electromagnet.
At the above-mentioned electromagnet that is used on the Sewing machines, have several installing holes on the horizontal fixed face of described installing plate.Installing hole is used for the top use that the horizontal fixed face is fixed on the Sewing machines oil groove.
Compared with prior art, originally be used for the first half position that access port that electromagnet on the Sewing machines is used to insert power line is in this side of installing plate, make that the access port of power line can not be immersed in the lubricating oil of oil groove.Fundamentally stop lubricating oil and infiltrated into electromagnet inside, and flowed back to the situation at Sewing machines electric cabinet place.

Fig. 3 is the structural representation of installing plate.
Among the figure, 1, iron core; 2, body; 3, power line; 4, installing plate; 41, vertical fixing face; 42, horizontal fixed face; 41a, fixing hole; 42a, installing hole; 5, through hole; 6, nut.
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.
As depicted in figs. 1 and 2, the electromagnet that originally is used on the Sewing machines comprises a body 2, and the both sides of body 2 are respectively equipped with iron core 1 and installing plate 4, and iron core 1 passes body 2, and can stretch after the electromagnet energising; Installing plate 4 is connected on the body 2, is inverted "L" shaped, is made up of with the right angle form vertical fixing face 41 and horizontal fixed face 42, has two installing hole 42a on the horizontal fixed face 42 of installing plate 4; Electromagnet also is connected with a power line 3 that feeds body 2 in installing plate 4 these sides, and the access port of power line 3 is in the first half position of electromagnet.
As shown in Figure 3, have a through hole 5 on the installing plate 4, the position of through hole 5 is corresponding with the position of power line 3 access ports, and power line 3 penetrates from this through hole 5, is linked in the body 2 of electromagnet by 3 access ports of the power line on the electromagnet again.Have two fixing hole 41a on the vertical fixing face 41 of installing plate 4, be provided with a connecting rod that is connected with body 2 among each fixing hole 41a, have screw thread on the connecting rod, screwing on nut 6 at the opposite side of vertical fixing face 41 again fixes, installing plate 4 and electromagnet dismounting can be come when needing, conveniently clean and install.
Be fixed together by screw thread between electromagnet ontology 2 and the vertical fixing face 41, horizontal fixed face 42 is fixed on the top of oil groove.And be fixed together with the right angle form between vertical fixing face 41 and the horizontal fixed face 42, thereby make electromagnet ontology 2 also together be fixed on the top of oil groove.Power line 3 passes through hole 5 successively and power line 3 access ports are connected to electromagnet ontology 2 inside.And, make the access port of power line 3 can not be immersed in the interior lubricating oil of oil groove because through hole 5 and power line 3 access ports are all opened the first half position at body 2.Electromagnet energising back iron core 1 gets final product work.
