Description

Winder

Technical field

The utility model relates to a kind of winding mechanism, is particularly useful for the folding and unfolding of the electric wire of household electrical appliance such as dust collecting fan.

Background technology

The electric wire of household electrical appliance has certain length usually, and connect with convenient, yet when household electrical appliance did not use, it is in disorder that unnecessary electric wire can seem, even influence people's walking or mobile thing, thereby, need utilize winder to furl electric wire.

Existing winder, generally include spiral support, elastic element and detent mechanism, electric wire on the spiral support, detent mechanism wherein, modal is the slide block latching device, during use, with hand moving slider latching device it is unclamped, the pulling electric wire is to suitable length, again with slide block latching device location, when wanting take-up, unclamp the slide block latching device once more, electric wire reclaims under the effect of elastic element automatically.This structure can realize furling and locating of electric wire, still, need remove to control the slide block latching device at the winder place, use inconvenience, simultaneously, when reclaiming, because the effect of elastic element, electric wire can reclaim fast, is difficult in interfix, again because electric wire reclaims too fast, wire end can get rid of, and casualty accident easily takes place.

The winder that adopts ratchet structure is also arranged, utilize the screens of ratchet to realize location and take-up, but its complex structure, Transmission is many, thereby the fault rate height, and excessive velocities causes the problem of hurting sb.'s feelings during simultaneously also unresolved take-up.

Summary of the invention

The utility model purpose provides a kind of winder that can realize automatic take-up, and this winder answers take-up steadily even, safe.

For achieving the above object, the technical solution adopted in the utility model is: a kind of winder, comprise by inner disc, outer dish and spiral prop up the line concentration mechanism that is configured to, one elastic element, and the detent mechanism of control sets line mechanism rotation, be provided with wiring construction in the spiral support, electric wire is electrically connected with wiring construction, and furl on the spiral support, described elastic element is positioned at inner disc one side, one end is connected with the spiral support, and described detent mechanism is made of the positioning groove in the inner disc outside and the flexible positioning piece that is positioned on the elastic element housing, and flexible positioning piece cooperates with the positioning groove position.

In the technique scheme, described " wiring construction " is used to realize being electrically connected between electric wire and the electrical equipment, because electric wire is around the axle rotation of spiral support, and therefore generally can be 2 groups of Elastic Contact or organize the copper ring structure more and realize with relatively rotating; Described " elastic element " is used for line concentration mechanism is applied back stretch, and when electric wire was drawn out, line concentration mechanism rotated to a direction, the elastic element energy storage, and when electric wire reclaimed, elastic element released energy, and drove line concentration mechanism counter-rotation, to regain electric wire; Described " flexible positioning piece " is connected on the elastic element housing, matches with positioning groove simultaneously, when pulling out electric wire, flexible positioning piece one end slides in positioning groove, during the location, it snaps in the limited bayonet of positioning groove, during recovery, the pulling electric wire, flexible positioning piece is deviate from limited bayonet, and when discharging electric wire again, flexible positioning piece enters in the positioning groove and slides, under the effect of elastic element, line concentration mechanism rotates and reclaims electric wire.

In the technique scheme, described positioning groove comprises water jacket, the inside groove of annular, be communicated with at least one group of locating groove of water jacket and inside groove and the ditch that leads, be provided with guiding step and limited bayonet in the described locating groove, the water jacket of the water jacket of self-align bayonet socket side, locating groove side, limited bayonet, inside groove are provided with step successively from shallow to deep, described guiding ditch is positioned at the limited bayonet rear, and self-align bayonet socket one side of inside groove to ditch one side that leads is provided with step from shallow to deep.Wherein, described " step " is meant the sudden change of groove at depth direction, is used for the projection on the flexible positioning piece is led, and it can only be moved toward dark direction by shallow along groove, and can not counter motion.When pulling out electric wire, projection enters in the water jacket and slides, when stopping, under the effect of elastic element, the counter-rotating of line concentration mechanism, at this moment, when the projection on the flexible positioning piece is inverted to the limited bayonet outer end along water jacket, because the spacing guiding of step, inwardly enter the limited bayonet place, the bayonet socket that is positioned is spacing, thus, line concentration mechanism is stopped operating; When needing to reclaim electric wire, spur electric wire once more, make projection leave limited bayonet, at this moment, because the limited bayonet place is more shallow than inside groove than outer groove depth, the projection of flexible positioning piece can not enter water jacket, and is subjected to the step guiding to enter inside groove, loosens electric wire, owing between inside groove and limited bayonet step is arranged, the projection of flexible positioning piece can not withdraw from, and along the inside groove slippage, under the restoring force effect of elastic element, electric wire is regained in the revolution of line concentration mechanism; When pulling out electric wire once more, projection can enter water jacket along the ditch that leads, thereby repeats said process, realizes the location of electric wire and recovery automatically.

In the technique scheme, inner disc is provided with 2 groups to 4 groups described locating grooves and guiding ditch, and each organizes locating groove and the circumferential rectangular distribution of guiding bank.

In the technique scheme, described elastic element can be a wind spring, is installed in the coil spring box, and flexible positioning piece one end and coil spring box are rotationally connected, and the projection of the other end cooperates with positioning groove, is provided with damping mechanism between described coil spring box and inner disc.Wherein, described damping mechanism is provided with damped ring for to be provided with inner gear on inner disc in coil spring box, is connected with the miniature gears that cooperates with inner gear on the damped ring.

In the technique scheme, described flexible positioning piece comprises spacer, spring leaf and projection, and projection is connected in an end of spacer, and with the positioning groove sliding block joint, the elastic force direction of spring leaf is towards the inner disc direction.Spacer plays a part to be connected, to support with coil spring box or elastic element housing, and projection is used for cooperating with positioning groove, and spring leaf applies elastic force to spacer and projection, makes projection be close to the positioning groove basal sliding.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

Since the utility model in the inner disc arranged outside of line concentration mechanism positioning groove, on the elastic element housing, be provided with the flexible positioning piece that matches, thereby as long as the pulling electric wire just can realize the location of electric wire easily and reclaim automatically, be convenient to operator's use;

2. moulding when positioning groove can be to the inner disc injection moulding, thereby detent mechanism is simple in structure, has only a rotation connection structure between flexible positioning piece and elastic element housing, the reliability height;

3. be provided with damping mechanism between inner disc and elastic element housing, when take-up, drive damped ring by the inner gear of inner disc, thereby make take-up speed even, the power lead of having avoided causing because take-up is too fast has got rid of hurts sb.'s feelings, safe.
