Principle of work of the present invention is as follows:
Axle I, axle II level connect fixes through fixing jackscrew 27, realizes two axles unifications, and diaxon outer end is stationary axle by fixing that jackscrew is fixed on support, and when cable reel rotates, diaxon does not rotate, shared main frame rotating mechanism; Be arranged on carbon brush on carbon-brush holder under spring pressure, cross section and slip ring surface close contact, play On current effect between cable I/O.
Cable automatic drawing refers to when cable is pulled out by external force (manpower), and reel rotates, and drives spring with core curling (energy storage), until rear locking decontroled by cable; When cable is decontroled, reel turns round under spring force effect, rolling cable.
After complete machine is fixing, due-in payout is fixed on output wiring board, connects cable and makes cable all enter groove.When external force drawn out cable, cable reel is forced to rotate, and drives carbon brush mechanism, spring case, ratchet to rotate thereupon, because of spring case cam ring, axle II effect, cam stings tight clockwork spring inner ring end points, cable reel is rotated and rolls tightly spring (energetically) simultaneously, produce elastic energy accumulation; When cable rolling, loosen cable, under the elastic force effect of spring case mechanism, cable reel automatic rotary (putting strength), drives cable rolling to enter groove, until rolling is complete.
Major part of the present invention structure and function as follows.
Cable reel: aluminum magnesium alloy is cast, and inner hollow core, outside intermediate circumference establishes cable duct, and cable duct is provided with output wiring board and service ports.Reel body connects with support, spring case, ratchet structure respectively.Function is rolling cable and drives the running of annular carbon brush supports, spring case, ratchet.
Spring case: spring case main body is box body, clockwork spring, cam, axle II, function is energy storage/release energy, and drive reel revolution, rolling cable enters groove.
Ratchet: plane ratchet, establishes 3 groups of ratchet groups for 120 degree each other, often organizes and establish 3 ratchets and 1 click-fit, reel is rotated 1 week, can do 9 stop points under the effect of ratchet automatic spring, realizes can doing any stopping/pull-out in twisted and released of the cable way.
Installation form of the present invention: product can vehicle-mounted parallel or at right angle setting, also can wall-hanging installation in machine fort.
Occupation mode of the present invention:
Install: by draw off gear screw fixed installation (horizontal vertical or wall-hanging), connect input lead by mark.Under the inelastic state of cable reel, roll up cable reel 13-14 circle with hand (band leather gloves) to cable-pull direction Pan.Adjust pre-off-position and put (reference cable output connection port upwards or backward position), be plugged safety pin.By cable termination through cable track adjusting wheel, connect cable by mark.After be sure oing that cable connects, loosen reel, extract safety pin, drawn out cable one section, when judging that reel loosens, slowly loosens cable, cable under elastic force effect by rolling in groove, until complete retracting cable.
Use: (1) is to aviation power supply: under electroless state, and drawn out cable plug, to aircraft energizer socket place, be sure of that cable is automatically locked by ratchet sour jujube grapple structure, be plugged plug signal power supply.Any stopping receiving/releasing can being done in its midway.
(2) aviation power supply is stopped: under electroless state, extract cable plug, pull one section, cable, ratchet sour jujube grapple structure is decontroled automatically, slowly loosens cable and make it regain completely.Any stopping receiving/releasing can being done in its midway.
The present invention also can be extended to electric retractable.The above know-why being specific embodiment of the utility model and using, any based on the equivalent transformation on technical solutions of the utility model basis, all belong within protection domain of the present utility model.
