Abstract

The utility model relates to a winder, which comprises an upper cover, a lower cover, a rotary shaft, a steel belt and a wire rod, wherein rotary shaft is arranged between the upper cover and the lower cover; the steel belt and the wire rod are respectively arranged inside and outside the rotary shaft; and the rotary shaft is provided with a steel ball groove containing steel balls. The winder is mainly used in products with longer lead wires such as a computer, a mouse and an earphone, thereby solving the problem of the prior art that wire rods tangle up due to longer length; meanwhile, the winder has a compact structure and convenient use; moreover, because the arrangement of the steel balls and the steel ball groove on the rotary shaft realizes simple operation during pulling out or putting back a wire rod, the winder has high popularization and use value.

Description

A kind of winder

Technical field

What this product related to is a kind of whirligig, a kind of specifically winder.

Technical background

Along with popularizing of digital product, computer, mp3 walkman, and derived product, mouse, earphone all are full of in people's life, yet the lot of data spider lines together, and be neither attractive in appearance, and tied up in knots is difficult to separately bring trouble to us.Such as the earphone cord of mp3, we go out to walk, and earphone cord will swing up and down, and can't settle earphone cord, so need a kind of winder, selects length as required, makes earphone cord press close to health, avoids unnecessary tangling and bothering.

The utility model content

Technical assignment of the present utility model is at above weak point, and a kind of winder is provided, and solves the defective that prior art exists.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of winder, its mechanism comprises loam cake, lower cover, rotating shaft, steel band, wire rod, described rotating shaft places between loam cake and the lower cover, described steel band and wire rod are separately positioned on the inside and outside of rotating shaft, offer the steel bead groove that steel ball is housed above the described rotating shaft.

Described loam cake is in the same place by screw with lower cover.

A kind of winder of the present utility model has following beneficial effect:

Be mainly used in above the long product of lead-in wires such as computer, mouse, earphone, solved in the prior art because the long mutual snarly trouble of wire rod, this winder structure compactness, practical and convenient, the steel ball in the rotating shaft and the setting of steel bead groove, simple operations when well having realized pulling out now or putting back to is so have good popularization practical value.

Embodiment

Explain below with reference to Figure of description a kind of winder of the present utility model being done.

A kind of winder of the present utility model, its mechanism comprises loam cake 1, lower cover 7, rotating shaft 4, steel band 5, wire rod 6, described rotating shaft 4 places between loam cake 1 and the lower cover 7, described steel band 5 and wire rod 6 are separately positioned on the inside and outside of rotating shaft 4, offer the steel bead groove that steel ball 3 is housed above the described rotating shaft 4.

Described loam cake 2 and lower cover 7 are fixed together by screw 1.

Motion process:

A) rotating shaft 4 rotates counterclockwise when both hands backguy 6, steel ball 3 is driven down by the steel bead groove of rotating shaft 4, does straight line back and forth movement (annotate: loam cake 2 has the anti-steel ball 3 of groove along the rotating shaft core rotation), simultaneously steel band 5 is had pretightning force, make rotating shaft 4 clockwise rotate potential energy, see Fig. 2.

B) when pulling line 6 action when stopping and unclamping in position shown in Figure 2, the pretightning force of steel band 5 clockwise rotates rotating shaft 4, simultaneously steel ball 3 under the steel bead groove of rotating shaft 4 drives toward axe movement, when steel ball 3 moves to Fig. 3 position, the stuck point 9 of steel ball 3 interlock rotating shafts 4 and block rotating shaft 4 and rotate.See Fig. 3.

C) in position shown in Figure 3, when pulling line 6, rotating shaft 4 rotates counterclockwise, and steel ball 3 enters the steel bead groove inner ring toward axe movement under the steel bead groove effect, simultaneously steel band 5 is had pretightning force, makes rotating shaft 4 that the potential energy that clockwise rotates be arranged.See Fig. 4.

D) when pulling line 6 action in position shown in Figure 4 and when continuing backguy to figure below D position, steel ball 3 to the steel bead groove outer ring, is seen Fig. 4 through steel bead groove Internal and external cycle transition point under the drive of steel bead groove.

E) when pulling line action when stopping and unclamping in position shown in Figure 4, the pretightning force of steel band 5 clockwise rotates rotating shaft 4, steel ball 3 is done the straight line back and forth movement at the inner ring of steel bead groove under the drive of steel bead groove simultaneously, and line 6 drives the winding of lower edge rotating shaft 4 sides in rotating shaft 4.

Claims

1, a kind of winder, it is characterized in that: its mechanism comprises loam cake, lower cover, rotating shaft, steel band, wire rod, described rotating shaft places between loam cake and the lower cover, and described steel band and wire rod are separately positioned on the inside and outside of rotating shaft, offers the steel bead groove that steel ball is housed above the described rotating shaft.

2, a kind of winder according to claim 1, it is characterized in that: described loam cake is in the same place by screw with lower cover.
