Abstract

The utility model relates to the technology field of wire rod deploying and retracting device, especially to a rotator modified structure of the unidirectional retracting wire device. The utility model includes an orbit plate, a gyrus line autorotation area formed between the orbit plate and the middle rotor plate, a centralizing lines area and a spring area formed between the middle rotor plate and the lower rotor plate, the center of the centralizing lines area is provided with a stele, the middle rotor plate is provided with a threading hole near the stele, two wire winding columns are integrate formed between the orbit plate and the middle rotor plate, the two wire winding columns are arranged in the center of the gyrus line autorotation area and be provided with a gap therebetween, the center of the rail guiding plate is provided with a cone. Since the two wire winding columns are created to one entirety between the orbit plate and the middle rotor plate, the two sides of the two wire winding columns are same in space, the wire rods are winding on the two wire winding columns through the gap between the two wire winding columns, so the wire rod kinking phenomenon will not happen for the two sides of the gyrus line autorotation area are same in space, the wire rod is deployed and retracted smoothly, furthermore the utility model is simple in structure, convenient in manufacture.

Description

The swivel structure-improved of unidirectional take-up

Technical field:

The utility model relates to the draw off gear technical field of wire rod, refers in particular to a kind of swivel structure-improved of unidirectional take-up.

Background technology:

At present, electronic machines such as computer peripheral equipment, earphone, mobile phone, mp3 all need to use the transmission wire rod and are connected with miscellaneous equipment or power supply, still long or too much when wire rod uses, carry Shi Junhui and cause the puzzlement of certain degree and desktop mixed and disorderly.In order to solve the problem that wire rod is long, too much and carry, freely to take in or extending apparatus so researched and developed a kind of wire rod that makes, this device can be placed in many products.But pursued gently for taking modernized product into account, thin, little, the life-span is long, and the computer peripheral equipment product need reach the requirement of plug and play, makes this device wire rod need one line must not connect segmentation, this device will face volume and the test on the life-span when the time comes.As shown in Figure 1, 2, this take-up keystone configuration is a swivel 101, a upper shell 102 and a lower house 103, and its lower house 103 is provided with a cylinder 104, hangs and the rotation of maintenance swivel 101 inertia but these cylinder 104 ammunition feed springs 105 collude.This swivel 101 is provided with line concentration district 110 and the spring region 111 that forms between loop line rotation district 108, turntable 107 and the lower rotary table 109 that forms between track plate 106, track plate 106 and the turntable 107, and swivel 101 centers offer the cylindrical hole 112 that penetrates for lower house.Upper shell 102 is provided with detent mechanism and screw hole is kept supplying lower house 103 assemblings.This device is prolongation wire rod service life, center pillar 113 an other post 114 or the arc thin slices of adding in loop line rotation district 108, make its wire coil on center pillar 113 and post 114, so no matter the wire rods in the loop line rotation district 108 are just to change or reverse, and wire rod can both be wound on post 114 and the center pillar 113.Because center pillar 113 and post 114 are not in the central authorities of turntable 107, make that post 114 and center pillar 113 are inequality to the space size at this device edge, with this device volume size when outlet is longer, will occur wire rod Chan in the loop line rotation district 108 around phenomenon, make that the wire rod retractable of winding box is smooth and easy inadequately.In sum, all there is unsatisfactory place in existing take-up.

The utility model content:

The purpose of this utility model is exactly the swivel structure-improved that a kind of unidirectional take-up is provided at the weak point of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is: it comprises line concentration district and the spring region that forms between loop line rotation district, turntable and the lower rotary table that forms between track plate, track plate and the turntable, line concentration district central authorities are provided with a center pillar, turntable is offering through wires hole near the center pillar place, one-body molded between turntable and the track plate have two wrapping posts, two wrapping posts have the space between central and two wrapping posts in loop line rotation district, rail godet central authorities form cone.

Lower rotary table offers knock hole in another surperficial central authorities of center pillar.

After adopting said structure, because turntable and track plate central one-body molded has two wrapping posts, make that the space size on two wrapping post both sides is identical, wire rod is wound on two wrapping posts by the space between two wrapping posts, can the phenomenon of Xian Cai Chan line not occur owing to space, both sides, loop line rotation district differs in size, the wire rod folding and unfolding is smooth and easy, in addition, the utility model is simple in structure, and is easy to make.

Fig. 6 be the combination of the utility model and upper and lower casing three-dimensional exploded view two.

The specific embodiment:

See shown in Fig. 3-6, the utility model comprises line concentration district 5 and the spring region 6 that forms between loop line rotation district 3, turntable 2 and the lower rotary table 4 that forms between track plate 1, track plate 1 and the turntable 2, line concentration district 5 central authorities are provided with a center pillar 7, turntable 2 is offering through wires hole 8 near center pillar 7 places, one-body molded between turntable 2 and the track plate 1 have two wrapping posts 9, two wrapping posts 9 are positioned at the central authorities in loop line rotation district 3, and have the space between two wrapping posts 9, track plate 1 central authorities form cone 10.The utility model can cooperate upper shell 11 and lower house 12 to be assembled into take-up, upper shell 11 central authorities offer through hole 13, lower house 12 central authorities form registration mast 14, during installation, the utility model is put into lower house 12, and registration mast 14 injects in the knock hole 15 of lower rotary table 4, covers upper shell 11 then, the through hole 13 that upper shell 11 surfaces are offered cooperates with cone 10, so just can guarantee that the utility model inertia in upper shell 11 and lower house 12 rotates.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
