Abstract
The utility model belongs to the technical field of sewing machines, and particularly relates to a sewing machine backstitch electromagnet. The sewing machine backstitch electromagnet comprises a coil and a shell body for fixing the coil, wherein an iron core which moves in an inner cavity of the coil after being powered on is arranged in the inner cavity of the coil, a guiding rod fixedly connected with the iron core is arranged outside the shell body, and the diameter of the iron core is larger than the diameter of the guiding rod. The sewing machine backstitch electromagnet is simple and stable in structure, small in vibration and noise when used, fast in installation, convenient to install and capable of improving working efficiency of sew machines.
Description
Technical field
The utility model belongs to the sewing machine technique field, refers in particular to a kind of electromagnet that backstitches of Sewing machines.
Background technology
At present, the application of electromagnet in Sewing machines is very extensive.Known electromagnet all adopts yoke directly to contact installing plate with the fixing structure of snap-fastener, and armature was up and down when such structure used, and made the whole vibrations of electromagnet very big, and result of use is poor, the life-span is short, and assembling bothers, and productivity effect is low.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, shake little assembling easily Sewing machines backstitch electromagnet.
The purpose of this utility model is achieved in that a kind of electromagnet that backstitches of Sewing machines, the housing that comprises coil and fixed coil, wherein, described coil inner chamber is provided with after the energising iron core that move in chamber in coil, and housing is outside equipped with the guide post of fixedlying connected with iron core; The diameter of described iron core is greater than the diameter of guide post.
According to the above a kind of Sewing machines backstitch electromagnet, wherein, the iron core of described guide post one side be provided with match with the coil inner chamber and be used for unidirectional spacing taper platform.
According to the above a kind of Sewing machines backstitch electromagnet, wherein, described coil inner chamber and iron core form matched in clearance.
According to the above a kind of Sewing machines backstitch electromagnet, wherein, described guide post upper end is provided with catch and the stop nut that contacts with housing when iron core moves respectively.
The utility model outstanding and beneficial technical effects compared to existing technology is: simple and stable structure, and vibrations and noise during use are smaller, and convenience quick for installation can improve the operating efficiency of Sewing machines.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is cutaway view of the present utility model;
Among the figure: 10-housing, 11-coil, 12-iron core, 13-guide post, 14-taper platform, 15-catch, 16-stop nut.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3: a kind of Sewing machines backstitch electromagnet, the housing 10 that comprises coil 11 and fixed coil, wherein, described coil 11 inner chambers are provided with after the energising iron core 12 that move in chamber in coil, and housing 10 is outside equipped with the guide post 13 of fixedlying connected with iron core 12; The diameter R of described iron core 12 is greater than the diameter r of guide post.
According to the above a kind of Sewing machines backstitch electromagnet, wherein, on the iron core of described guide post 13 1 sides 12 be provided with match with coil 11 inner chambers and be used for unidirectional spacing taper platform 14.
According to the above a kind of Sewing machines backstitch electromagnet, wherein, described coil 11 inner chambers and iron core 12 form matched in clearance.
According to the above a kind of Sewing machines backstitch electromagnet, wherein, catch 15 and stop nut 16 that described guide post 13 upper ends are provided with iron core 12 respectively to be contacted with housing 10 when moving.
After the utility model energising, iron core 12 is fast moving under the magnetic force that coil 11 produces promotes, and because coil 11 inner chambers and iron core 12 form matched in clearance, so in moving process, can produce vibrations hardly, and noise is very little, and the catch 15 of guide post 13 afterbodys and stop nut 16 can carry out the adjusting of position according to concrete operating position, stablizing with efficient when guaranteeing iron core 12 motions; When iron core 12 bounced back in the coil 11, taper platform 14 can timely spacing iron core 12, and can be good slow down iron core 12 retractions the time and the bump of coil 11.The utility model overall structure is simple, convenience quick for installation, the efficient in the time of improving Sewing machines work.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
