Abstract

The utility model relates to a telescoping wire box which is provided with double bidirectionally extendable, bidirectionally retreatable and rotatable rails. The telescoping wire box is composed of the following components: an upper housing 7, a lower housing 1, a wire coiling wheel 4, a spring 3, a rotation shaft 2, a central screw 8, a ball bearing 5, double rails 9, an upper wire outlet 6, a lower wire outlet 10 and wire coiling wheel fixing grooves 11. The rotation shaft of the lower housing is provided with one wire coiling wheel which has a basin-shaped structure. The basin opening is inserted into the wire coiling wheel fixing groove of the lower housing. The basin bottom is provided upwards and is provided with double rails. Two vortex grooves are provided above the double rails.

Description

Two backguy two-orbit line stretcher boxes

Technical field:

The utility model relates to a kind of line stretcher box, refers specifically to a kind of line stretcher box with biaxial tension, two-way contraction and dual swing-around trajectory.

Background technology:

The application of line stretcher is very extensive at present, especially at the fishing instrument, earphone cord, use on the computer peripheral device at most, patent of invention 981014593 has been introduced a kind of fishing reel and retract line device, be coil holder cover or hinge to be applied an extension displacement by coil tension spring, thereby fishing line is regained, this line stretcher device can only disposablely shrink, segmentation is carried out as required, the existing retract line box that is used on computer peripheral and the earphone cord, though can realize that segmentation is reclaimed and stretching, but because of it adopts the single file orbit, make data line very not steady when stretching and reclaim, cause data line to be broken easily, the use that influences whole line stretcher box is received the order.

The utility model content:

In order to solve the problem that exists in the above technical field, the utility model proposes following art solution.

The utility model comprises upper shell 7, lower house 1, reel 4, law 3, rotating shaft 2, center bolt 8, ball 5, dual track 9, last line outlet 6, following line outlet 10 and reel hold down groove 11, end at lower house 1 has two knock holees, the other end has two registration masts, line outlet 10 under in the middle of the registration mast being, there is reel positioning groove 11 centre, centre bit at reel positioning groove 11 is equipped with a central rotating shaft 2, this rotating shaft 2 is injected into one with lower house 1, have a groove vertically at the middle part of rotating shaft 2, this groove has been divided into two halves with rotating shaft, the center, upper end has a center screw, two housings is fixed in one to be used for inciting somebody to action up and down by center bolt, also be to be used for adjusting gap between rotating shaft and the reel by center bolt, so as to make reel can be steady rotate betwixt; One end of upper shell 7 has two registration masts, decide for two to have Top Leading-out Hole 6 in the middle of the scapus, two knock holees are arranged in the lower end of upper shell 7, a centre hole is arranged in the middle of it, last lower house is tightened in by centre hole the center screw with the rotating shaft of lower house on of center bolt by upper shell by four registration masts and four synthetic box bodys of knock hole; A reel 4 is installed in the rotating shaft 2 of lower house, reel 4 is the peviform structure, its basin mouth is embedded in downwards in the reel positioning groove 11 of lower house, make progress at the bottom of the basin, on at the bottom of this basin, have dual track 9, two whirlpool groove A and B are arranged on dual track 9, no matter dual track cw or left-hand revolution, all must be through the whirlpool groove, in the folder face of dual track 9 and upper shell 7, a ball 5 is arranged, the data line fixed plate is arranged in basin, the middle part has an axis hole at the bottom of basin, the whole piece data line turns back from the center, the inboard that the bending place is embedded into reel 4, pull out from the last line outlet of upper shell 7 by the wire casing that goes out of reel 4 upper end, another goes out wire casing and pulls out from the following line outlet of lower house by reel in the lower end, a coil tension spring that screws is arranged in reel, one end of spring hangs in the rotating shaft, the other end hangs on the data line fixed plate of reel inboard, the coil tension spring that screws has certain stress relief, this stress impels the reel right-hand revolution, and this moment, data line was constantly regained from two wire holes up and down, twist in reel 4 above.When data line when two ends are drawn back, under the effect of two pulling force, reel is rotated in a clockwise direction, because the direction of outwarding winding naturally of law also is a clws, so when drawing back data line, law is screwed, produce certain stress, when pulling force removes, under the effect of law stress, reel is from the rotation of trend anticlockwise direction, and this moment, ball reversed along track, it is locked to slip into the whirlpool groove, no longer retreat, when pulling out out some data lines once more and when loosing one's grip at once, ball will roll down along normal orbit, at this moment, data line is retracted and has twisted on the reel.

The beneficial effects of the utility model are by increasing the orbit of a reel, reel is operated steadily in order, and the partition running of line is very steady, and not only feel is soft, and is difficult for the corrupt data line, has effectively prolonged the service life of product.

Description of drawings:

Figure (1) is an exploded view of the present utility model.

The specific embodiment:

Because the data line two ends are around on the reel along same direction, when the data line end of two line outlets about the line stretcher box is pulled out simultaneously, reel begins to rotate, coil tension spring is tightened up, and produces certain force of strain, when data line length reaches when necessarily requiring, stop drag data line, this moment, reel began reversing, in dual owing to the effect of coil tension spring tension force, the ball of reversing is preferentially slipped in the groove of whirlpool, blocked reel it can not be rotated, at this moment, as long as draw data line before continuing, then decontrol rapidly, ball will be walked out the whirlpool groove, along conventional track reversing, up to data line is all regained.

Claims

1. two backguy two-orbit line stretcher box, form by upper shell, lower house, reel, law, rotating shaft, center bolt, ball, dual track, last line outlet, following line outlet and reel hold down groove, it is characterized in that in the rotating shaft of lower house, being equipped with a reel, reel is the peviform structure, its basin mouth is embedded in downwards in the reel positioning groove of lower house, upwards, at the bottom of this basin, have dual track at the bottom of the basin.

2. by the described a kind of pair of backguy two-orbit line stretcher box of claim 1, it is characterized in that on dual track, having two whirlpool grooves (A, B).
