Description

Novel flat linear electromagnetic shaker

Technical field

This utility model relates to a kind of electromagnetic shaker, relates in particular to a kind of novel flat linear electromagnetic shaker.

Background technology

In fields such as medical treatment, health cares, flat electromagnetic shaker is installed usually in widely used massage couch, the massage armchair.Chinese patent ZL20082012437.4 discloses a kind of platypelloid type linear vibrator, as shown in Figure 1, the casing 1 and the end cap 5 that comprise flat round pie, in casing 1 and end cap 5, be provided with loop coil 7 and vibration component, end cap is equipped with coil rack 10 on 5 bottom surfaces, loop coil 7 is wrapped on the coil rack 10, vibration component is "T"-shaped pouring weight 2 by the cross section that bonds together, be positioned at the annular magnetic steel 3 of pouring weight 2 wide end one sides, annular reed 4 and annular yoke 8 are formed, loop coil 7 is placed in the narrow end and the space between the annular yoke 8 of pouring weight 2, loop coil 7 usefulness glue are fixed on the centre of end cap 5, annular reed 4 evenly is provided with the annular of 3 Ka Jiao with holes for periphery, the one end is bonded between annular magnetic steel 3 and the annular yoke 8, one end links together by screw and casing 1 and end cap 5, the centre of end cap 5 is provided with opening, by metallic data plate 9 sealings, annular magnetic steel 3 is for end face magnetizes, and the outside of the outside of pouring weight 2 and annular yoke 8 is provided with bumper 6.

Yet its coil rack 10 adopts aluminium foil or Copper Foil to constitute, junction between itself and the end cap 5 is easy to generate minim gap under the long-time high-intensity vibration of platypelloid type linear vibrator, and the time send in vibrations and to make a noise, coil rack 10 even can come off when serious from end cap 5.In addition, annular reed 4 also makes a noise because of platypelloid type linear vibrator long-term vibration produces distortion easily.

The utility model content

The novel flat linear electromagnetic shaker that provides a kind of noise low is provided the purpose of this utility model.

For achieving the above object, this utility model provides a kind of novel flat linear electromagnetic shaker, comprise end cap, base, coil rack and annular shell fragment, described end cap and described coil rack one constitute, between described end cap and the base locating ring is installed, described annular shell fragment is installed between described locating ring and the described base, described end cap, described locating ring, be connected and fixed by bolt between described annular shell fragment and the described base, the end face of described locating ring and its circumference of upper edge, bottom surface are respectively equipped with that several are paired, equally distributed alignment pin, described end cap, correspondence is provided with first dowel hole corresponding with described alignment pin position on described annular shell fragment and the described base, second dowel hole and the 3rd dowel hole, described first dowel hole of insertion that described alignment pin cooperates, in described second dowel hole and described the 3rd dowel hole.

Novel flat linear electromagnetic shaker of the present utility model, described alignment pin is roughly cylindrical.

Novel flat linear electromagnetic shaker of the present utility model, the material of described end cap is a high-temperature resistance plastice.

The end cap of novel flat linear electromagnetic shaker of the present utility model and coil rack one constitute, noise takes place with regard to having been avoided the junction between end cap and the coil rack because of vibrations produce minim gap in this, and saved the operation of being connected between end cap and the coil rack, reduced cost, in addition, between end cap and the base locating ring is installed, the annular shell fragment is installed between locating ring and the base, the end face of locating ring and its circumference of upper edge, bottom surface are respectively equipped with that several are paired, equally distributed alignment pin, end cap, correspondence is provided with first dowel hole corresponding with alignment pin position on annular shell fragment and the base, second dowel hole and the 3rd dowel hole, insertion first dowel hole that alignment pin cooperates, in second dowel hole and the 3rd dowel hole, so annular shell fragment is more firm under the positioning action of locating ring, is not easy to be out of shape and to make a noise because of the vibrations for a long time of flat linear electromagnetic shaker.
