Background technology
Winding roll is used for carrying out folding and unfolding to power lead, when the length of power lead is longer, is convenient to arrange power lead, according to required power lead length, is pulled out by power lead in winding roll, and it is fixing to carry out " brake " after adjusting to suitable length.
Automatic winding disc of the prior art, such as: the patent No. is 201120121385.9, the Chinese utility model patent that name is called " winder brake trigger bar and winder brake release gear " is utilize brake trigger bar (comprising key part, elastic part and axis hole) to realize brake release disclosed in this patent; Application number is 201110270914.6, the Chinese invention patent application that name is called " brake structure of winder ", disclosed in be utilize ratchet wheel pawl type brake assemblies and friction type brake assembly to realize the brake structure of dual brake function.Winding roll device disclosed in above two sections of patent documentations, its brake, the equal more complicated of releasing structure, adopt parts more, component structural more complicated.To the material cost of winding roll, manufacturing cost and reliability all bring adverse influence.
Summary of the invention
The technical issues that need to address of the present invention are: existing automatic winding disc, its brake, releasing structure more complicated, the parts adopted are more, component structural more complicated, it is brake, the equal more complicated of releasing structure, and adopt parts more, component structural is complicated, to the material cost of winding roll, manufacturing cost and reliability all bring adverse influence.
The present invention takes following technical scheme:
A kind of automatic winding disc, the External Force Acting that the spiral that described automatic winding disc is wound around automatically is rolled under the effect of elastic recovery mechanism, described winding roll is provided with inner groove 1, outer groove 2, kelly 5, and the plush copper of described kelly 5 to be stuck in described inside and outside annular groove 1,2 and to slide along it; Extending in the process launched at spiral, if the path of motion direction of kelly 5 plush copper is outwards, otherwise is inside; Described inner groove 1 is smoothly communicated with outer groove 2 by connecting groove 3, and connecting groove 3 side is other has step I with the adjacent position of inner groove, and connecting groove 3 is positioned at the subordinate of step I; Described outer groove 2 is outside with connecting groove cohesive position, and through outer groove first section of 2a, be provided with step II at the end of outer groove first section of 2a, described outer groove first section of 2a is positioned at the higher level of step II, and outer groove secondary segment is positioned at step II subordinate; Lambdoid draw-in groove 4 is provided with between the reference position of outer groove secondary segment, inside and outside annular groove, the entrance of draw-in groove 4 is provided with step III, draw-in groove 4 is positioned at the subordinate of step III, the outlet of draw-in groove 4 is communicated with inner groove 2, be provided with step IV between the outlet of draw-in groove 4 and inner groove 2, inner groove 2 is positioned at the subordinate of step IV.
The technical program implementation process is as follows:
When electric wire be positioned at tighten up state time, the plush copper of kelly 5 is inserted in inner groove 1, electric wire pull-out is extended, electric wire drives winding roll to rotate, the hinge-point of kelly 5 does not rotate thereupon, but the plush copper of kelly 5 is stuck in inner groove 1, relative movement is there is with inner groove 1, when the plush copper of kelly 5 moves to the position of connecting groove 3, due to the existence of step I, plush copper slides in outer groove 2 along connecting groove 3, and continue conter clockwise slip relative to outer groove 2, through outer groove first section of 2a, get out of a predicament or an embarrassing situation II, cross draw-in groove 4, due to boss get out of a predicament or an embarrassing situation II time can sound, suggesting effect is had to operator, operator unclamps electric wire, electric wire the automatic recovery under the effect of elastic recovery mechanism, plush copper moves to reversing sense, due to the existence of step II, plush copper cannot get back to first section of outer groove, get out of a predicament or an embarrassing situation so take advantage of a situation and III enter draw-in groove 4, and be stuck in draw-in groove 4, electric wire stretches out the distance of one section of setting, and maintain static, now, as electric wire regained, only need again electric wire be pulled out, winding roll rotates again, and plush copper pulls out from draw-in groove 4, due to the existence of step III, plush copper can not get back to outer groove secondary segment, and move from the other end of lambdoid draw-in groove 4 to inner groove 1, finally move in inner groove 1, under the effect of elastic recovery mechanism, continue electric wire all to reclaim.
Further, described connecting groove 3 has the gradient upwards from inner groove 1 to outer groove 2.Owing to pull out and in the process reclaimed when electric wire, the plush copper of kelly 5 is all the time " getting out of a predicament or an embarrassing situation ", to realize the function stoping its reverse walking, therefore the gap on this height is made up in certain position needs gradient arranged upwards, the gradient is arranged on connecting groove 3, is beneficial to enforcement, also facilitate the processing of mould.
Further, described automatic winding disc comprises the wire spool arranging inside and outside annular groove, and with described wire spool just to the chuck assembled of fitting, described kelly 5 is hinged on chuck.Wire spool and chuck are set, realize reasonably assembling.
Further, described automatic winding disc from core radially outward, be provided with many group inner groove 1, outer groove 2, draw-in groove 4, stretch out and launch and fix, and obtains the length that multiple coiling is stretched out by coiling classification.By arranging many group inner groove 1, outer groove 2, draw-in groove 4, the cut to lengthen of multistage electric wire can be realized.
Further, what coil in described winding roll is electric wire.
Further, described elastic recovery mechanism is wind spring sheet.
Beneficial effect of the present invention is:
1) structure is simple, and the parts of the position-limiting action realize elongation, brake is located, regained are only wire spool and a kelly of an integrated injection molding.
2) parts are few, and assembling is simple.
3) easy to use, soft handle.
4) easily extensible is multistage stretching length and realizes brake location.
5) commercial value is large, has the market outlook of wide popularization and application.
Accompanying drawing explanation
Fig. 1 is electric wire when tightening up state, the birds-eye view of wire spool.
Fig. 2 is that electric wire stretches one end apart from when also brake is located, the birds-eye view of wire spool.
When Fig. 3 is electric wire pull-out, before kelly does not also arrive chevron pointing draw-in groove 4, the birds-eye view of wire spool.
Above three width accompanying drawings are illustrated to the position of kelly all simultaneously.In fact, kelly is hinged on the chuck that assembles of fitting corresponding to wire spool.
