Abstract
The utility model discloses the technical field of a light industrial sewing device; in particular discloses a half internal arranged uplifting pressure electromagnet mechanism. The electromagnet mechanism comprises an electromagnet, a back cover plate, a knee controlling lever and a knee controlling connecting rod; wherein, the electromagnet is a screw electromagnet which is fixedly jointed with an electromagnet bracket and inlaid into the back cover plate. The connecting unit at end part of the electromagnet bracket is fixed onto the back cover plate, too. The rolling shaft iron core of the electromagnet is fixed provided with a crank, the other end of which is articulated with a driving connecting rod. The other end of the driving connecting rod is provided with a through groove which is articulated with the knee controlling connecting rod and the knee controlling lever through a pin shaft. The utility model has the advantages that the adopted half internal arranged structure makes the overall structure compact, and thus the volume of the exposed part is smaller than one forth of the old mechanism; the height of an uplifting leg is much larger; the packing materials and common machine modes can be generally used and the costs on management, packing and transport all are reduce. Furthermore, the utility model still has the advantages of simple structure, easy and convenient component production and installation, less mobile part and fault.
Description
Affiliated technical field:
The utility model relates to the light industry technical field of sewing equipment, is specifically related to a kind of half built-in piezoelectricity magnet mechanism of lifting.
Background technology:
At present, electric sewer adopts complete external plug-type electromagnetism back mechanism to come presser foot lifter, and push-pull electromagnet is wholy set in head back outside, and volume is excessive, and packing case, packing foaming are all different with common type, and management cost and packed and transported cost are big; In order to set up electromagnet, also need to be provided with special-purpose support, accessory complex structure, assembly manufacturing, installation trouble; When breaking down, maintenance is inconvenient.
Summary of the invention:
The purpose of this utility model is that a kind of half built-in piezoelectricity magnet mechanism of lifting will be provided, to overcome volume big, complex structure, management cost and the big shortcoming of packed and transported cost that prior art exists.
For overcoming the problem that prior art exists, the technical solution of the utility model is: a kind of half built-in piezoelectricity magnet mechanism of lifting, comprise electromagnet 7, back shroud 8, knee control lever 2 and knee control connecting rod 3, it is characterized in that: described electromagnet 7 is rotary magnets, electromagnet 7 is fixedly linked on the electromagnetism brandreth 9, electromagnet 7 is embedded in the back shroud 8, and the connector 10 of electromagnetism brandreth 9 ends is fixed on the back shroud 8; Be fixed with crank 6 on the rotating shaft iron core 5 of electromagnet 7, the hinged kinematic link 4 of crank 6 other ends, the other end of this kinematic link 4 is provided with groove, and this groove is hinged by bearing pin and knee control connecting rod 3 and knee control lever 2.
The arranged outside of electromagnet 7 has two centrosymmetric circular arc slide openings 1 on the above-mentioned back shroud 8, and the connector 10 of electromagnetism brandreth 9 ends is arranged at wherein.
The outer setting of above-mentioned electromagnet 7 has protective cover.
Compared with prior art, the utility model has the advantages that: adopted half built-in structure, made compact overall structure, it exposes volume not until old 1/4 of mechanism; The presser foot lifter height is higher; Packaging material and common type can be general, reduced management cost and packed and transported cost; Simple in structure, assembly manufacturing, simple installation; Moving component is few, not easy break-down.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the B of back shroud among Fig. 1 is to view.
Description of reference numerals is as follows:
1-circular arc slide opening, 2-knee control lever, 3-knee control connecting rod, 4-kinematic link, 5-rotating shaft iron core, 6-crank, 7-electromagnet, 8-back shroud, 9-electromagnetism brandreth, 10-connector.
The specific embodiment:
Explain below in conjunction with accompanying drawing team the utility model.
Referring to Fig. 1～Fig. 2, the electromagnet 7 that the utility model comprises electromagnetism brandreth 9 and is fixedly connected with it, said electromagnet 7 is rotary magnets, electromagnet 7 is embedded in the back shroud 8, electromagnetism brandreth 9 ends are provided with two connectors 10, and this connector 10 is fixedly set on the back shroud 8, in two centrosymmetric circular arc slide openings 1 in electromagnet 7 outsides.Rotating shaft iron core 5 ends of electromagnet 7 are fixed with crank 6, the hinged kinematic link 4 of the other end of crank 6, and the other end of this kinematic link 4 is provided with groove, and this groove is hinged by bearing pin and knee control connecting rod 3 and knee control lever 2.
The multiple mode that has been fixedly connected of electromagnetism brandreth 9 and electromagnet 7 can be that electromagnetism brandreth 9 is realized connecting with its periphery welding, also can be to be fixed on the end face of electromagnet 7.The shape of electromagnetism brandreth 9 can be varied, as long as the structure that makes things convenient for its end to connect with back shroud all can adopt.Circular arc slide opening 1 on the back shroud 8 is the position of adjusting electromagnet 7 accurately for more convenient, also can reach same effect with intensive company's hole Motionless electromagnetic brandreth 9.
Operation principle: when needs are adjusted the push-and-pull length of knee control connecting rod 3, connector 10 between electromagnetism brandreth 9 and the back shroud 8 is unclamped, connector 10 is rotatable certain angle in circular arc slide opening 1, electromagnetism brandreth 9 is being with electromagnet 7 rotations, tighten connector 10 after adjusting to the right place again, reach the purpose of regulating magnet 7 idle strokes,, finally adjust the presser feet height with this swinging distance of adjusting knee control connecting rod 3.After the energising, electromagnet 7 rotates, and crank 6 is rotated, and drives kinematic link 4 work, drives 2 swings of knee control lever, affects 3 push-and-pulls of knee control connecting rod, finishes Sewing machines presser foot lifter function.
