Abstract
This invention discloses a shaft cable device with a timely braking function including an outer box,a wire coil carrying cables in the box and two supporting frames set at both sides of the wire coil characterizing that a shaft hole is opened at the center of the supporting frame having a slant with an obliquity theta to the level direction, the shaft of the coil slides and rotates along the slant and theta is greater than 0deg. and smaller than 90deg.. This device is in a self-sink damp design solving the problem of releasing continuously because of inert action after stopping discharge.
Description
Technical field
The present invention relates to a kind of cable with axle sabot tool, relate in particular to the shaft-mounted cable device that used in HF transmission communication cable or Packaging For Optical Cable are used with timely braking function.
Background technology
Today of economic globalization, packing combines together with commodity.Packing in production, circulation, sale and consumer field, is being brought into play important role as the means that realize commodity value and value of service.The function of packing is the protection commodity, transports safely, makes things convenient for use, promotion, and adapts to the different consumer groups' needs.Along with the popularization and application of the communications cable, safety analysis from electric transmission performance, long-distance transport and use, shaft-mounted cable becomes preferred manner of packing.But shaft-mounted cable commonly used is packaged in and is prone to inertia in the wiring and rotates automatic unwrapping wire, be wound in junction phenomena, hinders and continues unwrapping wire and use.When the communications cable when drum is emitted, the tension force that cable is subjected to mainly is wiring unit or the operating personal pulling force to it, increase along with pulling force, drum self can produce inertia and rotate, drum can continue automatic unwrapping wire under effect of inertia when stopping unwrapping wire, and the cable of emitting automatically is irregular alignment, is wound in knot.Cable just is difficult to emit during follow-up like this use, influences efficient.Simultaneously, the communications cable phenomenon that is wound in knot has had a strong impact on electric transmission performance.
Summary of the invention
At the problems referred to above, the present invention adopts the formula damping design of drowning oneself, and has solved the problem that existing cable installation effect of inertia when unwrapping wire stops to continue outlet, rubs with increasing by the structure of improving axis hole, realizes braking rapidly.
In order to realize the foregoing invention purpose, the technical solution used in the present invention is to have the shaft-mounted cable device of timely braking function, comprise exterior casing, be placed on one in the casing and can carry drum and two bracing frames that place drum both sides in the casing respectively of cable, it is characterized in that
Center at bracing frame offers axis hole, and described axis hole has one and with horizontal direction the inclined-plane of one inclination angle [theta] arranged, and the axle of drum slides along this inclined-plane and rotates, wherein: 0 °＜θ＜90 °.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, from detailed description of the present invention, above-mentioned and other purposes of the present invention, feature and advantage will be apparent.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the front view that removes behind the casing.
The specific embodiment
See also shown in accompanying drawing 1 and 2, shaft-mounted cable device with timely braking function of the present invention, comprise exterior casing 1, be placed on one in the casing 1 and can carry the drum 2 of cable, for drum 2 is erected in the casing 1, also adopt the bracing frame 30,31 of two support usefulness, placed the both sides of drum 2 in the casing 1 respectively.Center at bracing frame 30,31, offer an axis hole (only illustrated among the figure 3 bracing frames 31 on axis hole 32) respectively, the axle of drum 2 (only having illustrated one 21) is fastened in the axis hole 32, like this, the weight of the cable on the drum 2 can pass to bracing frame by the axis hole on two bracing frames of beam warp and bear, because bracing frame is the isosceles trapezoid shape, therefore can share the weight of cable and drum preferably.Offer unwrapping wire hole 11 in casing 1 one sides, cable contained on the drum 2 is by 11 outlets of unwrapping wire hole.
Improvements of the present invention are, the axis hole of traditional bracing frame 30,31 central authorities improved, and be example with axis hole 32, adopted non-circular hole, on axis hole 32, designed one especially and be the inclined-plane of an inclination angle [theta] with horizontal direction.Under the unwrapping wire state, the axle of drum 2 will slide along this inclined-plane and rotate.0 °＜θ＜90 ° wherein, and this inclination angle [theta] is to be clockwise rotated by the horizontal alignment bevel direction to form.
Because the unique texture of this axis hole 32, under the effect of unwrapping wire pulling force, the axle of drum 2 leaves the nadir of bracing frame axis hole 32, i.e. initial position when rotating.In the unwrapping wire process, the weight on the drum 2 is the once linear decreasing function with the backguy time.
In case when stopping unwrapping wire, drum 2 will be got back to initial position, violent friction takes place with the anti-slip material 3 that is arranged on casing 1 bottom, make the speed of drum 2 be reduced to 0 in the short time at the utmost point, drum 2 stops operating fast, realize snap catch by the damping of drowning oneself, prevent that cable from continuing unwrapping wire under effect of inertia, eliminate the winding of cable thus.
In addition, the further definite of inclination angle [theta] can be depended on following formula:
θ＝arcctg((G-μ*F)/(F+μ*G))
Wherein, μ is the axle and the coefficient of sliding resistance of stay bearing plate, the weight G of a wiring dish and shaft-mounted cable, the maximum pull F that cable bears.
Bracing frame 30,31 can also adopt shapes such as oblong, square.
The present invention is broken through from structure design, be applied in cable especially in the design of communication cable or Packaging For Optical Cable, on the requirement basis of mechanical characteristics that satisfies EIA/telecommunications industry association EIA/TIA-568B and Chinese YD/T1019-2001 and transmission performance, experienced test chronically and test strictly, made accordance and practicality obtain sufficient authentication.
More traditional circular axis hole bracing frame and bracing frame of the present invention, aspect take-up, unwrapping wire, the latter is all good in the former, and two kinds of structures all satisfy the requirement of mechanical properties.
The front provides the description to preferred embodiment, so that any technical personnel in this area can use or utilize the present invention.Various modifications to these embodiment are conspicuous to those skilled in the art, can be applied to other embodiment to total principle described here and not use creativeness.Thereby, the embodiment shown in the present invention will be not limited to here, and the wide region of principle that should disclose and new feature according to meeting here.
