Description
Technical field the utility model relates to the gentle line quickly retracting device of a kind of trailing type, more particularly, relates to and a kind ofly can be used for flexible band, drawing fast of flexible wires hung take-up.
Background technology in the prior art; existing can be used for flexible band, drawing fast of flexible wires hung take-up; the disclosed take-up of CN2411701Y has following shortcoming: its structure is complicated, component part is many, volume is big, motion is stable inadequately; and usually return that machinery to occur malfunctioning as the card line is tight, skid or phenomenon such as not take-up of locking, thus its assembly process how and productive costs higher.
The summary of the invention the purpose of this utility model is to provide a kind of simple in structure, compact conformation, flexible operation, reliable and stable, simple installation and the high gentle line quickly retracting device of trailing type of production efficiency.
In order to achieve the above object, the utility model provides following technical scheme: design the gentle line quickly retracting device of a kind of trailing type, reel is rounded and be rotating shaft with the center of circle, have back cover (1) and fore shell (2) and tool shell chamber, this distributor also has mesochite (3), banded spring (4), drag hook (5), extension spring (6), dead man (7), actuation button (8) and backguy (9), there is well-distributed teeth groove (12) outer of mesochite (3), twine the number of turns more than the banded spring (4) of backguy (9) number of turns when twining fully be positioned at the shell chamber of mesochite (3) and its around to backguy (9) around to opposite, one end of extension spring (6) links to each other with the dead man (7) that is fixed on the back cover (1) by gong silk or rivet (11) by the hole on the dead man (7), being positioned at the cylindrical actuation button (8) that is active state of housing outer and an end of dead man (7) is in contact condition all the time and withstands actuation button (8) by dead man (7), the other end of dead man (7) rides on the teeth outline of mesochite (3) and be positioned at teeth groove (12) under lock-out state, the size of the contact jaw of dead man (7) and teeth groove (12) and shape adapt with teeth groove (12), and the other end that the end has a backguy (9) of drag hook (5) is fixed on the mesochite (3) and around the outer of mesochite (3).
The utility model technical scheme preferably can be: shell rim has trough (10) on the corresponding position up and down, in addition, screw hole (15) and two double-screw bolts (16) that setscrew is used of also having two assembling usefulness on the relevant position of housing, owing in use be, be added with aforesaid structure and be convenient to its two exchange use the use in parallel of described two distributor dos-s.
The utility model technical scheme preferably also can be: the front end of actuation button (8) has bellend, the circular arc of top for matching with teeth groove (12), and the size and the shape of the guide hole (14) at actuation button (8) place adapt with it.This design is for the sliding distance that limits actuation button (8) and guarantees that it can not deviate from guide hole (14), and the top is that activity is freely in teeth groove (12) in order to make actuation button (8) for the semicircle that can match with teeth groove (12).
The utility model technical scheme preferably can be again: one side of the tooth head (13) on teeth groove (12) both sides is slick and sly camber line, and another side has the tip that is formed by the interior curved arc shape alveolar surface and the flank of tooth.Like this, can guarantee that actuation button (8) is in operation in good time and the activity of in position going up is deviate from freely or enter in the teeth groove (12), to finish unwrapping wire or take-up operation smoothly.
In implementing process of the present utility model, Winder is rotating shaft with the center of circle, and coiling remains on the circumference, has guaranteed when backguy evenly smooth and easyly, tangentially twines during take-up, and the device motion freely; Banded spring (4) be positioned at mesochite (3) the shell chamber and its around to backguy (9) around to opposite, the winding number of turns of banded spring (4) is more than the number of turns of backguy (9) when twining fully, for take-up provides certain propulsion source, power is increased with the amplitude of backguy; Dead man (7) is the distortion lever, the supporting-point of lever is fixed on the housing, dead man can be in certain amplitude range rotates around supporting-point, and resetting of dead man is by at the other end of dead man locking extension spring (6) being installed, and the elastic force of extension spring (6) forces dead man to reset.Under the effect of extension spring (6), actuation button (8) is in contact condition all the time and withstands actuation button by dead man (7) with an end of dead man (7), the other end rides on the teeth outline of mesochite (3), in case this end motion enters teeth groove, it is promptly locked to move, and backguy (9) motion stops, and surpasses certain value when backguy (9) is stressed, the end that dead man (7) rides on the teeth outline just is forced to withdraw from teeth groove, and the backguy campaign is promptly proceeded; In addition, dead man of the present utility model (7) is preferably half-cylindrical with the contact jaw shape of mesochite (3), and the gullet base on the mesochite (3) is preferably circular arc, to reduce the sliding resistance and the wearing and tearing of dead man locking end, makes the retractable cable operational movement freely.
Operational process of the present utility model: drag hook (5) is under the effect of power, drawing coupled backguy (9) outwards pulls out it, mesochite (3) rotates around center shaft under the effect of tangential direction power, the rotation of mesochite (3) forces outer end banded spring (4) fixed thereon to tighten up around the mesochite axis direction, the rotation of mesochite (3) embeds teeth groove to dead man (7) and produces the moment around the rotation of dead man self axle, and the dead man built-in end is broken away from.Stop backguy, the stressed elimination of backguy (9), mesochite (3) has rotating tendency under the effect of banded spring (4) elastic force, and dead man (7) embeds the teeth groove of mesochite (3) under the effect of extension spring (6), and mechanism is in stabilized conditions.When actuation button (8) when being subjected to pressing, dead man (7) embeds the teeth groove end and deviates from teeth groove, and mesochite (3) drives backguy (9) in the effect turning down of banded spring (4) elastic force and reclaims.
Compared with prior art, the utlity model has following tangible advantage: 1, simple in structure, simple installation and compact conformation, the utility model is according to the structure needs of take-up and control part, adopt circular integral structure as housing, actuation button is installed on the circumference of noise made in coughing or vomiting housing, has greatly reduced its volume and has taken up an area of the space; 2, flexible operation, stable and reliable operation and service efficiency height: because it is rational in infrastructure and part is few, can not produce mechanical breakdown and mechanism is malfunctioning, can not take place ply-yarn drill tight, skid and phenomenon such as not take-up of locking.
