Description
Technical field
The utility model relates to a kind of winding roll, refers to specifically that a kind of structure and manufacture craft are simple, manufacturing cost is lower, easy to operate and can satisfy the telescopic automatic winding roll of the supporting demand of different household appliances.
Background technology
At present, multiple drawing automatic winding roll has appearred on the domestic and international market, a kind of " the drawing automatic winding roll of dust catcher " of China's utility model patent number 03020633.4, it comprises low bottom-disc, winding roll and the upper cover plate that they are covered, clockwork spring twists in winding roll upper side center, the winding roll centre bore is sleeved on the central shaft that is installed in the upper cover plate center, can rotate around central shaft, be respectively equipped with electric conductor at the downside of winding roll and the center of low bottom-disc, two place's electric conductors are in contact with one another conduction, an arresting lever that can freely swing is housed on the downside of winding roll, the movable end of arresting lever is provided with the scotch of projection, be provided with corresponding two radial symmetric groove muscle and pits on low bottom-disc, scotch contacts with the groove muscle is movable when swing.
Scotch on above-mentioned " the drawing automatic winding roll of dust catcher " employing arresting lever cooperates guiding and the pit blocking is arranged with the groove muscle on the low bottom-disc, can prevent that winding roll from reversing, and be limited in a certain length after power line pulled out, it does not take the dust catcher confined space, makes this dust catcher trend towards miniaturization.Yet the conductive structure that adopts above-mentioned winding roll and low bottom-disc to be in contact with one another is comparatively complicated, is unwell to the supporting use of some household appliances.
The utility model content
Technical problem to be solved in the utility model is exactly the present situation at above-mentioned prior art, is limited in a certain length after a kind of power line can being pulled out, and can prevents that reel from reversing, not establishing in addition button and telescopic automatic winding roll simple to operation and provide.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of telescopic automatic winding roll, it comprises a reel and the support that covers mutually, the centre bore of this reel is sleeved on the central shaft of described support and can rotates around this central shaft, described reel is connected with wind spring, be provided with the ratchet that can swing along the ratchet bearing pin at least in this reel, described wind spring is installed in the coil spring seat of described support; The initiating terminal of this wind spring is buckled on the described reel, and the other end of this wind spring is buckled on the interstage sleeve in the described coil spring seat;
It is characterized in that:
A. be positioned at reel center circle groove simultaneously and be provided with a cam that matches with ratchet;
B. by described ratchet bearing pin this ratchet is fixed on the described reel, it can be freely swung in restriction range, described ratchet and reel can rotate around the axle center of described cam;
C. the ratchet round pin on cam and the ratchet is combined with outer ring gathering sill and inner ring gathering sill, and transitional region therebetween is connected with braking gathering sill and the transition work nest that lead-over groove forms respectively in turn.
As preferably, described braking gathering sill has two, and it is that centre bore rotation with cam is arranged symmetrically on its periphery, conveniently makes and uses.
As improvement, described braking gathering sill bottom surface is formed by connecting by transition inclined-plane that highly is lower than gathering sill bottom surface, outer ring and the transition inclined-plane that is higher than inner ring gathering sill bottom surface, is the limited mouth of braking action in the junction, and good braking effect is used easily.
As improvement, described transition work nest is the skewed slot that is communicated with outer ring gathering sill and inner ring gathering sill, and its outboard end bottom land height is higher than the outer ring gathering sill, and medial extremity bottom land height is lower than the inner ring gathering sill.Described transition work nest has two, is to be symmetrically arranged on the periphery with the rotation of the centre bore of cam.
Improve again, the optional position motion of ratchet between cam on the one hand, ratchet is when the ratchet bearing pin moves up and down to dominant bit displacement place on the other hand, ratchet and detent pin still have the gap in vertical direction, ratchet can be swung freely in the restriction site scope, thereby realize that ratchet moves along gathering sill fully.
Further improve, cam places in the center circle groove of reel, and its diameter is less, makes the distance between the braking gathering sill shorter, thereby realizes that the using pawl to brake stroke shortens, and makes operation more flexible, and is convenient.
Further improve, described ratchet along the fixedly nose end of ratchet be provided with one stretch out have certain flexible support curved bar, the movable end of this ratchet is provided with the ratchet round pin of upper process.During its work, in reel, be subjected to force compresses and elastic reset, can move up and down and can swing, guarantee operate as normal thereby realization ratchet round pin contacts the braking gathering sill of cam fully along the ratchet bearing pin around it.
Further improve, the limited mouth that cooperates with the ratchet round pin adopts double horn degree of lip-rounding formula, makes ratchet when the ratchet round pin rotates, again certain swing can be arranged vertically, to satisfy the requirement of ratchet slip brake in cam braking gathering sill.
Further improve by the scope of the confined space control ratchet in the reel behind the installation cam, guarantee that the ratchet round pin can guarantee the operate as normal of winding roll fully along braking gathering sill work around the detent pin swing.。
Compared with prior art, because advantage of the present utility model is: adopt cam to be fixed on the interior structure of reel, the ratchet round pin is done curvilinear motion in the braking gathering sill of cam, and there is breaker slot to brake, can prevent that reel from reversing, be limited in a certain length after power line pulled out, and by the scope of the confined space control ratchet in the reel behind the installation cam around the swing of ratchet bearing pin, guarantee that the ratchet round pin can guarantee the operate as normal of winding roll fully along the work of braking gathering sill.It does not establish button in addition, take the confined space of household appliances less, and it is simple to operation, make these household appliances trend towards miniaturization and hommization, total is reasonable, makes assembling easily, simplify the structure and manufacture craft, reduce manufacturing cost, and can satisfy the supporting demand of different household appliances, thereby have more the market competitiveness.
