The specific embodiment
By describing technology contents of the present utility model, structural attitude in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
see also Fig. 1 to accompanying drawing 4, a kind of cable tube coiling appts that shown in accompanying drawing, the utility model provides, comprise shell 1, mandrel 2, hanger, wind spring lid 3 and volute spiral spring 4, cable 5 is wound on wind spring lid 3, mandrel 2 passes shell 1, wind spring lid 3 and volute spiral spring 4 also are fixed on hanger, hanger can be contained in any position, described wind spring lid 3 rotating being arranged on mandrel 2, one end of described volute spiral spring 4 is fixed on wind spring lid 3, the other end is fixed on mandrel 2, also be provided with rotation stop device in described shell 1, brushgear housing 6 and brush contact seat 7, described brushgear housing 6 is fixed on wind spring lid 3 sides and can covers 3 together rotations along with wind spring, be provided with conducting ring 13 on brushgear housing 6, conducting ring 13 is electrically connected to cable 5, be provided with electric wire lead-in wire 8 on described shell 1, described brush contact seat 7 is fixed in shell 1, on brush contact seat 7, corresponding conducting ring 13 positions are provided with contact frame 9, be provided with spring 10 between described contact frame 9 and brush contact seat 7, spring 10 is against contact frame 9 on conducting ring 13, described contact frame 9 is connected with electric wire lead-in wire 8 electric wire lead-in wires 8.
Be provided with the opening that current supply cable 5 stretches out on shell 1, can direct pull cable 5, in the process that pulls, wind spring lid 3 rotates, volute spiral spring 4 holds power, and rotation stop device is realized that cable 5 is pullled and is stopped to optional position and self-locking, random length is pulled out according to demand, and cable 5 can be realized the automatic winding withdrawal after fulfiling assignment, easy to operate, safe and reliable, as to reduce cable 5 damage.
The present embodiment has designed the New-style electrical wire connection mode, with reference to accompanying drawing 2,, to accompanying drawing 4, can realize the monolateral fixing linkage function of monolateral rotation.Be inlaid with two conducting rings 13 on brushgear housing 6, conducting ring 13 back sides have the wiring stitch can coordinate the female plug connection terminal, realize being electrically connected to of conducting ring 13 and cable 5, and brushgear housing 6 can cover 3 with wind spring and rotate.Can tumble in two contact framves 9 and a grounding jumper contact on brush contact seat 7.Contact and contact frame 9 are connected by the female plug connection terminal with the external lead wire electric wire, the spring 10 that arranges can be against contact frame 9 on conducting ring 13 in use always, realize being electrically connected to of electric wire lead-in wire 8 and cable 5, reduce the sparking phenomenon, and easy installation and removal, even period of service is long 9 skews of contact frame or contact frame 9 can not occur yet not to be touched conducting ring 13 and cause being electrically connected to and lost efficacy, whole service life is long.
Concrete, contact frame 9 is the conductive cap of a projection, and spring 10 is arranged in conductive cap, and an end props up the top of conductive cap projection, and the other end is fixed on contact frame 9.
In the present embodiment, the material of described conducting ring 13 is copper ring, has guaranteed the conduction of whole circuit.
In the present embodiment, with reference to accompanying drawing 5, described rotation stop device comprises ratchet 11 and ratchet 12, and ratchet 11 is fixed on mandrel 2, and described ratchet 11 includes tooth district and anodontia district, and described ratchet 12 is hinged on the rotating disk eccentric position, is provided with torsion spring on ratchet 12.
After cable is pulled out from line outlet, 3 rotations of wind spring lid, along with cable draws longer and longer, wind spring lid 3 under the effect of volute spiral spring 4, is laid in increasing revolution potential energy, ratchet 11 tooth district and anodontia district are arranged is continuous, be semicircle.
when length that cable-pull is certain, and then together rotation of wind spring lid 3 of ratchet 12, after stopping drag, ratchet is followed 3 revolutions of wind spring lid, when ratchet 12 is encountered the profile of tooth that the tooth district is arranged, ratchet 12 withstands on the profile of tooth in tooth district, thereby wind spring lid 3 can't continue revolution, cable 5 can not regained, when needs retracting cable 5, continue to pull out the cable of certain-length, make ratchet 12 corresponding with anodontia district, and ratchet 12 is under the effect of torsion spring, swing to opposite side, thereby ratchet 12 can not head on the profile of tooth in tooth district, follow loose cables 5, cable 5 just can continue to regain under the effect of revolution potential energy.
The mode that ratchet 11 is fixed on mandrel 2 is a variety of, can directly adopt ratchet 11 directly to be set on mandrel 2, adopts flat key or spline to realize that both is fixing.
Novel cable tube coiling appts can be widely used in factory floor, industrial and mining enterprises and engineering, mechanical erection maintenance, and the fields such as Motor Maintenance are safe and reliable, and the shell in the present embodiment 1 and the 3 employing qualitative carbon steel moulding of wind spring lid, structure is firmer, and prolonged difficult use is easy to install.
Process through plastic-blasting at shell 1 and wind spring lid 3 surfaces in addition, be not easy to get rusty and oxidation.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
