Embodiment
Referring to figs. 1 through Fig. 3, the utility model conversion socket is described further with dust-proof mechanism embodiment.
A kind of conversion socket dust-proof mechanism, comprise the dust guard 1 of being located between pin and jack, dust guard 1 includes the cover plate 11 being covered on pin, cover plate 11 is placed in Socket casing 2, pin and jack are separated, cover plate 11 is provided with two grafting through holes 111 with respect to jack place, cover plate 11 convexes with center pole 112 in the middle of the axle center of grafting through hole 111, the central axis of center pole 112 and the central axis of two grafting through holes 111 are in same plane simultaneously, on center pole 112, be arranged with the butterfly 12 being rotationally connected, cover plate 11 is provided with the limiting section 113 that rotary limited baffle plate 12 covers grafting through hole 111 in rotation process, on center pole 112, be arranged with for making butterfly 12 contact at the reduction torsion spring 13 of limiting section 113, therefore butterfly 12 can be because fitting in limiting section 113 all the time under normal condition under the active force of reduction torsion spring 13, grafting through hole 111 is covered, butterfly 12 is provided with lozenges 121 with respect to the opposite side of grafting through hole 111, lozenges 121 is towards limiting section 113 1 side settings, be that one end that lozenges 121 gradients are low is towards limiting section 113, therefore when the pin conflict lozenges 121 of external plug, butterfly 12 can rotate towards the opposite side of limiting section 113.When needs are used conversion socket and external plug are inserted in jack, the pin of external plug and lozenges 121 are conflicted and are made butterfly 12 around center pole 112 rotations, until the pin under the pin of external plug and dust guard 1 plugs, to reach electric energy output object, easy to use, and this structure can not cause because external force is excessive butterfly 12 to damage, and has improved the dustproof stability of dust guard 1; By external plug when conversion socket pulls away, butterfly 12 meeting reverse rotations under the active force of reduction torsion spring 13, until fit in limiting section 113, be that butterfly 12 torsion spring 13 that is reset is fixed on initial position, and grafting through hole 111 is covered, guaranteed that butterfly 12 can play dustproof action effect, be that conversion socket is under not use state, butterfly 12 can fit in all the time limiting section 113 under the active force of reduction torsion spring 13, be covered in grafting through hole 111 simultaneously, be therefore convenient to realize by dust guard 1 dust-proof effect of conversion socket.
Described reduction torsion spring 13 includes the first reverse arm 131 that is positioned at head end and the second reverse arm 132 that is positioned at end, described center pole 112 is provided with for being embedded the first draw-in groove 1121 of the first reverse arm 131, and described butterfly 12 is provided with for being embedded the second draw-in groove 122 of the second reverse arm 132.The first reverse arm 131 is turned round and is turned towards reduction torsion spring 13 inner sides, conveniently be embedded in the first draw-in groove 1121, the second reverse arm 132 is turned round and is turned towards reduction torsion spring 13 outsides, conveniently be embedded in the second draw-in groove 122, not only facilitate the installation of reduction torsion spring 13 to fix, and the stability while being conducive to improve torsion spring carrying torque load.Each circle of reduction torsion spring 13 can be arranged to separately simultaneously around, make retention gap between its each torsion spring circle, conveniently when being subject to External Force Acting, by reduction torsion spring 13, provide certain axial elastic force when butterfly 12, play the effect of buffering.
Described cover plate 11 convexes with respect to a side of butterfly 12 slope, top 114 that the structure that is in the shape of the letter V arranges.When external plug is inserted in jack, the pin of external plug and lozenges 121 are conflicted can be by butterfly 12 around center pole 112 rotations, and butterfly 12 is when rotating, butterfly 12 rotates with respect to fitting slope, top 114, the side of cover plate 11 1 sides, in the time of can avoiding cover plate 11 inner side diapires to be planar structure and produce larger frictional force, therefore push up slope 114 and can reduce the frictional force of butterfly 12 when rotating, butterfly 12 is rotated dexterousr, avoid external plug because external force is excessive, to cause butterfly 12 to damage, improved the stability in use of dust guard 1.
Described butterfly 12 becomes globoidal structure setting with respect to the end of grafting through hole 111 both sides.Avoid butterfly 12 because its seamed edge and cover plate 11 madial walls or limiting section 113 produce, to interfere in rotation process, so the end of butterfly 12 becomes globoidal structure setting, can make butterfly 12 rotate smoothly around center pole 112.
