Abstract
The utility model relates to a device for preventing an earphone cord from being wound, consisting of the earphone cord, an upper group of fixed pulleys, an upper barrel body, a lower barrel body, a lower group of fixed pulleys, a positioning screw and a compression spring, wherein the inner upper wall of the upper barrel body is welded with the upper group of fixed pulleys, and is provided with a through hole for penetrating the cord; the lower barrel body is welded with the lower group of fixed pulleys and is provided with a through hole for outgoing of the cord, and the outer side wall of the lower barrel body is provided with a thread through hole; the compression spring is arranged in the lower barrel body, the upper barrel is sheathed in the lower barrel body and is arranged on the compression spring in a contacting and pressing manner; and the earphone cord entering the upper barrel body through the through hole is repeatedly bent by the lower fixed pulleys and the upper fixed pulleys continuously in sequence, and extends out of the through hole of the lower barrel body. When the earphone cord is retracted into a space formed by the upper barrel body and the lower barrel body, only the positioning screw is unscrewed. Under the effect of restoring force of the compression spring, the distance between the upper group of fixed pulleys and the lower group of fixed pulleys is lengthened. When the earphone cord needs to be lengthened, the outgoing end of the earphone cord is pulled. Therefore, the distance between the upper group of fixed pulleys and the lower group of fixed pulleys can be shortened. After the extended length of the earphone cord is determined, only the positioning screw is screwed.
Description
Affiliated technical field
The present invention relates to a kind of device that anti-principal vertical line twines, especially a kind of device that is used for the earphone cord winding.
Background technology
As everyone knows, the purposes of earphone more and more widely.No matter be study and the amusement under people's study, amusement, the especially public arena, people must use earphone.Yet the people that often use earphone also have their worry, and for example, the winding of earphone cord is usually made troubles to application.No doubt, also there is inventor's solution on this question to release the invention of oneself, but also has many unsatisfactory aspects.
The purpose of this utility model is: provide a kind of earphone cord that winding no longer occurs to people.The present invention adopts frame modes such as assembly pulley, spring return, chute orientation, by retrieval, finds no the invention of identical structure.
Summary of the invention
The device that a kind of anti-earphone cord twines, it be by earphone cord, on organize fixed pulley, upper barrel body, lower barrel body, group fixed pulley, dog screw, compression spring constitute down;
It is protruding that the madial wall that the cross section of the upper barrel body shape that is rectangle, the lateral wall that is welded with the through hole organizing fixed pulley, upper wall and be provided with threading, staving admittedly at the interior upper wall of upper barrel body are provided with axial chute, staving is provided with retaining;
The cross section of the lower barrel body shape that is rectangle is welded with group fixed pulley down admittedly and is provided with the through hole of outlet on the lower inner wall of lower barrel body, its lateral wall is provided with tapped through hole; Upper barrel body is being enclosed within the lower barrel body of shape movingly;
The compression spring that its cross section is rectangle places in the lower barrel body and presses at the compression spring on it by upper barrel body; Earphone cord enters upper barrel body from the through hole of threading, and continuous successively with earphone cord through group fixed pulley down, on organize the curved repeatedly of fixed pulley and put, then the through hole by the lower barrel body outlet stretches out.
Beneficial effect of the present invention: effectively prevent the winding of earphone cord, provide very big convenience for people use earphone.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is the upper barrel body structural representation.
Fig. 3 is the lower barrel body structural representation.
Fig. 4 is compression spring structure schematic diagram.
Among each figure, 1, earphone cord, 2, on organize fixed pulley, 3, upper barrel body, 31, through hole,
32, retaining is protruding, and 33, chute, 4, lower barrel body, 41, through hole, 42, tapped through hole,
5, following group fixed pulley, 6, dog screw, 7, the compression spring.
Embodiment
The utility model shown in Figure 1 by earphone cord (1), on organize fixed pulley (2), upper barrel body (3), lower barrel body (4), group fixed pulley (5), dog screw (6), compression spring (7) constitute down; Upper barrel body (3) is being nested with in lower barrel body (4) of shape movingly, and presses on compression spring (7); Dog screw (6) is to revolve with its tapped through hole of lower barrel body (4) (42) joins shape, and the dog screw (6) that at this moment enters chute (33) is born the effect of two aspects:
One, when it was screwed, fixedly the cover seated position between upper barrel body (3) and lower barrel body (4) had also just been located the distance between last group of fixed pulley (2) and following group fixed pulley (5);
Its two, when it does not screw, be in the chute (33) it and guaranteed the orientation of slip between upper barrel body (3) and lower barrel body (4) again.
Earphone cord (1) enters upper barrel body (3) from the through hole (31) of threading, and continuous successively with earphone cord (1) via organize down fixed pulley (5), on organize the curved repeatedly postpone of fixed pulley (2), stretch out by the through hole (41) of lower barrel body (4) outlet; Because the inwall of upper barrel body (3) is provided with retaining protruding (32), so place the earphone cord (1) in the space that upper and lower staving constitutes mutual touching can not occur.
When earphone cord (1) needed in the space that indentation upper barrel body (3) and lower barrel body (4) constitute, people only need unscrew dog screw (6) and get final product.Because of under the effect of compression spring (7) its restoring force, the distance between upper and lower group of fixed pulley is elongated, for this reason in the space that earphone cord (1) has been taken in by the lengthening of upper barrel body (3) and lower barrel body (4) formation.
When if its overhanging length of earphone cord (1) need extend, the end of going out of pulling earphone cord (1) its underpart that can be artificial.Under the effect of pulling force, the distance between one, upper and lower group of fixed pulley is shortened; Its two, the compression spring (7) further compressed.After treating that its overhanging length of earphone cord (1) is determined, people screw dog screw (6) and get final product.
Claims (1)
1. device that anti-earphone cord twines, it be by earphone cord, on organize fixed pulley, upper barrel body, lower barrel body, group fixed pulley, dog screw, compression spring constitute down; It is characterized in that: the cross section of the upper barrel body shape that is rectangle is welded with admittedly at the interior upper wall of upper barrel body (3) that through hole (31), its lateral wall that group fixed pulley (2), upper wall be provided with threading is provided with axial chute (33), its madial wall is provided with retaining protruding (32); The cross section of the lower barrel body shape that is rectangle is welded with group fixed pulley (5) down admittedly and is used for the through hole (41) of outlet on the lower inner wall of lower barrel body (4), its lateral wall is provided with tapped through hole (42); The compression spring (7) that its cross section is rectangle places in the lower barrel body (4), and upper barrel body (3) is being enclosed within the lower barrel body (4) of shape movingly, and presses at compression spring (7) on it.
