Abstract
The earplug reducing the winding of earplug wire relates to earplug, particularly earplug wire.For reducing the probability that earplug wire is wound around, three of earplug movable heads are fixed up by the utility model.Technical scheme is: two earplugs and plug are fixed together.The first structure: wire fixes a stainless steel cylinder near earplug position, the wire of plug is fixed a permanent magnet; Stainless steel cylinder replaces with magnetorheological elastoplast.The second structure: fix a fixed band on the wire of earplug plug lower end, there is an air bag fixed band inside, and the end of fixed band has fixed leg and circular hole respectively.Beneficial effect: due to the attraction of magnet, is fixed together earplug and plug, decreases the probability that earplug wire becomes fast knot; After stainless steel cylinder is replaced to magnetorheological elastoplast, less to the change of wire to earplug; In air bag, the effect of air and the elasticity of fixed band and frictional force are conducive to the relative position keeping plug and earplug, avoid sliding.
Description
Technical field
The utility model relates to earplug, particularly earplug wire.
Background technology
Because earplug has three movable heads, two earplugs and a plug respectively, after the pocket of clothes or knapsack put into by earplug, earplug wire forms several circle, is subject to Action of Gravity Field or shake, and one of them or multiple movable head fall into one or more circle, form fast knot, when taking out earplug, the wire making earplug in order is cumbersome, and likely pulls apart wire.
Summary of the invention
For reducing the probability that earplug wire is wound around, three of earplug movable heads are fixed up by the utility model.
The technical scheme that the utility model realizes goal of the invention employing is: reduce the earplug that earplug wire is wound around, comprise earplug, wire, plug, it is characterized in that: two earplugs and plug are fixed together.
The first structure: wire is close or contact earplug position, and the wire of each earplug is fixed a stainless steel cylinder, stainless steel cylinder can by attraction; The wire of plug is fixed a permanent magnet, distance between the upper surface of permanent magnet and the lower surface of plug is at 1-2cm, the shape of permanent magnet is cuboid, magnetic field intensity is in 200-400 Gauss, there is a through hole at center, permanent magnet upper and lower end face, this through hole passes for wire, through hole both sides are by the mode fixing cord of molten rubber, there is a semicircular groove two of permanent magnet or four sides, the large 0.1-0.2mm of radius of the semicircular radius ratio stainless steel cylinder of groove.
Stainless steel cylinder replaces with magnetorheological elastoplast.
The second structure: fix a fixed band on the wire of earplug plug lower end, fixed band is made up of elastic caoutchouc, the distance of upper end and plug lower end that fixed band admittedly leads position on wire is at 1-2cm; Fixed band is near one end of wire, there is an air bag fixed band inside, an atmospheric gas is held in air bag, the end of fixed band has fixed leg and circular hole respectively, fixed leg is near wire side, circular hole is positioned at the side away from wire, fixed leg has a spherical cap and a columniform pillar to form, the spherical diameter in its top is greater than bottom body diameter, circular hole is inserted in the spherical caps of fixed leg by the elasticity of fixed band, then utilize fixed band elasticity to recover, fixed band is fixed on the cylinder of fixed leg.
The beneficial effects of the utility model: due to the attraction of magnet, earplug and plug are fixed together, three of earplug movable heads are fixed, thus decrease the probability that earplug wire becomes fast knot, although the round that earplug wire is formed mutually to be wound around, the knot that can be undone by a pull be wound of round is similarly tied the shoelace, must elasticity but be that wire has from different place of tying the shoelace, knot that can be undone by a pull can not closely be wound around; After stainless steel cylinder is replaced to magnetorheological elastoplast, do not change the effect that it is attracted, but magnetorheological elastoplast is soft, less to the change of wire to earplug; The air bag of fixed band has good elasticity, can expand and shrink, and is conducive to circular hole and is inserted in fixed leg, and after fixing, in air bag, the effect of air and the elasticity of fixed band and frictional force are conducive to the relative position keeping plug and earplug, avoid sliding.

Embodiment
Example 1
Near (referring to that the distance of earplug 1 lower end and stainless steel cylinder 4 upper end is at 1-2cm) or contact on the wire of earplug 1 position, the wire of each earplug 1 is fixed a stainless steel cylinder 4, stainless steel cylinder 4 can by attraction, stainless steel cylinder 4 can replace with magnetorheological elastoplast, its shape is the same with stainless steel cylinder 4 with size, by plastics and iron powder, mixed-forming at certain temperature and pressure forms magnetorheological elastoplast, magnetorheological elastoplast is a kind of prior art, is not describing in detail.
The wire 2 of earplug 1 plug 3 is fixed a permanent magnet 5, permanent magnet 5 is bottom plug, distance between the upper surface of permanent magnet 5 and the lower surface of plug 3 is at 1-2cm, the shape of permanent magnet 5 is cuboid, within magnetic field intensity 400 Gauss, preferred 200-400 Gauss, there is a through hole at center, permanent magnet 5 upper and lower end face, this through hole passes for wire, through hole both sides are by the mode fixing cord of molten rubber, there is a semicircular groove any both sides of permanent magnet 5 (referring to front and back or left and right directions), the semicircular radius of groove is equal with the radius of stainless steel cylinder 4, or slightly large 0.1-0.2mm, theoretically, semicircular radius is equal with the radius of stainless steel cylinder 4, contact gear ratio is tightr, but there is the deficiency that when taking out, friction is larger, slightly greatly a bit, contact-making surface can be reduced, thus friction during less taking-up, extend its useful life.
Example 2
The wire of the lower end of earplug plug 3 is fixed a fixed band 6, its fixed form can adopt the bonding of prior art, or other usual way, the distance of fixed band 6 upper end and plug 3 lower end relatively, preferably at 1-2cm, fixed band 6 is near one end of wire, there is an air bag 9 fixed band 6 inside, the end of fixed band 6 has fixed leg 8 and circular hole 7 respectively, fixed leg 8 is near wire side, circular hole is positioned at the side away from wire, fixed leg 8 has a spherical cap and a columniform pillar to form, the spherical diameter in its top is greater than bottom body diameter, circular hole 7 is inserted in the spherical caps of fixed leg 8 by the elasticity of fixed band 6, then fixing elasticity is utilized to recover, be fixed on the cylinder of fixed leg.
