[0036] The technical scheme of the utility model is further illustrated below by specific embodiments in conjunction with the drawings.

[0037] As shown in Figures 1-3 The utility model discloses an embodiment provides a double coil structure, it includes two coil assemblies 1, each coil assembly 1 includes framework 11 and winding 12 that winds on framework 11.

[0038] Among two framework 11, one framework 11 along its axial both ends, first end is provided with first rotary connecting portion, and second end is provided with first clamping portion;Another framework 11 along its axial both ends, first end is provided with second rotary connecting portion, and second end is provided with second clamping portion.

[0039] When two framework 11 are spliced, first rotary connecting portion and second rotary connecting portion are first rotated and connected, and two framework 11 are rotated and approached, and when two framework 11 are rotated in place, first clamping portion and second clamping portion are clamped.

[0040] In the double coil structure, first rotary connecting portion and second rotary connecting portion are rotated and connected, since first rotary connecting portion and second rotary connecting portion are non-elastic structure, first rotary connecting portion and second rotary connecting portion can improve the connection firmness after being connected, and first clamping portion and second clamping portion are clamped, so that two framework 11 are connected with each other, and the assembly is simple and convenient, and the firm splicing of two coil assemblies 1 can be realized without new parts.

[0041] Optionally, the first rotating connection part is one of the rotating shaft 111 and the rotating groove 113, the second rotating connection part is the other of the rotating shaft 111 and the rotating groove 113, the rotating shaft 111 and the rotating groove 113 both extend along the radial direction of the framework 11, and the rotating shaft 111 and the rotating groove 113 are rotationally connected; the first clamping part is one of the clamping convex platform 1121 and the clamping concave groove 1141, and the second clamping part is the other of the clamping convex platform 1121 and the clamping concave groove 1141, and the clamping convex platform 1121 and the clamping concave groove 1141 are clamped and connected.

[0042] Optionally, the first end of each framework 11 is provided with the first rotating connection part and the second rotating connection part which are spaced apart along the radial direction of the framework 11, and the second end of each framework 11 is provided with the first clamping part and the second clamping part which are spaced apart along the radial direction of the framework 11, that is, the two frameworks 11 are provided with the same structure, the first end of each framework 11 is provided with the rotating shaft 111 and the rotating groove 113 which are spaced apart along the radial direction of the framework 11, and the second end of each framework 11 is provided with the clamping convex platform 1121 and the clamping concave groove 1141 which are spaced apart along the radial direction of the framework 11. When the two frameworks 11 are spliced, one framework 11 is arranged relative to the other framework 11 in alignment, so that the rotating shaft 111 and the rotating groove 113 of one framework 11 are opposite and connected to the rotating groove 113 and the rotating shaft 111 of the other framework 11, and the clamping convex platform 1121 and the clamping concave groove 1141 of one framework 11 are opposite and clamped to the clamping concave groove 1141 and the clamping convex platform 1121 of the other framework 11. This structure design makes the structures of the two frameworks 11 the same, without the need to distinguish, reducing the difficulty of the processing technology; and by simultaneously providing the rotating shaft 111 and the rotating groove 113, and the clamping convex platform 1121 and the clamping concave groove 1141 on the framework 11, the firmness is improved.

[0043] Of course, in other embodiments, the structures of the two frameworks 11 spliced with each other can also be different, that is, the first end of one framework 11 can be provided with only one or more rotating shafts 111, and the second end can be provided with only one or more clamping convex platforms 1121, and the first end of the other framework 11 can be provided with only rotating grooves 113 corresponding to the rotating shafts 111, and the second end can be provided with only clamping concave grooves 1141 corresponding to the clamping convex platforms 1121.

[0044] Optionally, along the radial direction of the framework 11, the inner end of the rotating groove 113 is provided with a blocking part 1131. This structure makes the two rotating shafts 111, after being rotationally connected to the two rotating grooves 113, move and adjust the coil assembly 1 along the radial direction of the framework 11, so that the rotating shaft 111 abuts against the blocking part 1131, realizing adjustment of the relative position of the two frameworks 11, and further making the clamping of the clamping convex platform 1121 and the clamping concave groove 1141 more smooth, improving the assembly efficiency.

When two skeletons 11 are spliced with each other, the extension 114 on one skeleton 11 can be limited in the recessed groove 112 on the other skeleton 11. In this structure, the extension 114 is limited in the recessed groove 112, which further improves the splicing strength of the two skeletons 11.

[0046] In order to make the extension 114 enter the recessed groove 112 more smoothly, the cross section of the recessed groove 112 and the extension 114 can be provided as a trapezoidal shape, a triangular shape or a semicircular shape, and the cross section of the recessed groove 112 and the extension 114 is not limited here. Optionally, the recessed groove 112 is provided as an open groove at the bottom of one skeleton 11 and the opening is directed to one side of the other skeleton 11. From the opening of the recessed groove 112 to the other side of the opening, the width of the recessed groove 112 gradually decreases, and the width of the extension 114 of the other skeleton 11 correspondingly decreases along the direction in which the width of the recessed groove 112 decreases. When the extension 114 of one skeleton 11 enters the recessed groove 112 of the other skeleton 11, the opening of the recessed groove 112 is larger, and the end of the extension 114 is smaller, so that when the two skeletons 11 are rotated and clamped, the extension 114 can enter the recessed groove 112 more smoothly.

[0047] The double-coil structure further includes a static core mounting plate 13, and the static core is mounted on the static core mounting plate 13.

[0048] Since the clamping boss 1121 and the clamping groove 1141 are elastically designed, the wall thickness at the extension 114 and the recessed groove 112 is relatively thin, and there is a possibility of deformation when the two skeletons 11 are spliced and subjected to external force.

[0049] In order to solve the above problem, optionally, the second end of each skeleton 11 is further provided with a buckle 14, and the two buckles 14 are symmetrically distributed, and the static core mounting plate 13 is mounted between the two buckles 14. That is, after the clamping boss 1121 and the clamping groove 1141 of the two skeletons 11 are clamped, the static core mounting plate 13 is mounted between the two buckles 14, and the static core mounting plate 13 can effectively prevent the phenomenon that the clamping boss 1121 and the clamping groove 1141 are disengaged due to the rotation of the two skeletons 11. That is, only when the static core mounting plate 13 is disassembled, the two skeletons 11 can be separated.

[0050] Specifically, the buckle 14 comprises clamping plates 141 and limiting bosses 142 arranged on the clamping plates 141, each clamping plate 141 can be provided with two limiting bosses 142 or a plurality of limiting bosses 142, the limiting bosses 142 on the two clamping plates 141 are arranged on the opposite sides of the two clamping plates 141 respectively, the static iron core mounting plate 13 is arranged between the two clamping plates 141, and the static iron core mounting plate 13 is limited between the limiting bosses 142 and the second end of the skeleton 11 towards the end portions of the two clamping plates 141 respectively. The buckle 14 structure can further improve the structural strength of the static iron core mounting plate 13.

[0051] Optionally, the opposite sides of the two clamping plates 141 are provided with reinforcing ribs 143, each clamping plate 141 can be provided with three reinforcing ribs 143 distributed along the radial direction of the skeleton 11, and the reinforcing ribs 143 are connected to the clamping plate 141 and the second end of the skeleton 11, so as to further enhance the structural strength of the clamping plate 141.
