The object of the present invention is to provide a kind of arrangement of clutch for switch cubicle operating mechanism, it has, and structure is simple, volume is little and reliable stable feature, to solve in prior art for the problems referred to above that the arrangement of clutch of switch cubicle operating mechanism exists.
For reaching this object, the present invention by the following technical solutions:
A kind of arrangement of clutch for switch cubicle operating mechanism, it comprises drive unit, worm screw, worm gear, power transmission shaft, ratchet and pivot pin, wherein, the output connecting worm of described drive unit, described worm screw is meshed with described worm gear, described power transmission shaft is arranged at the center of described worm gear rotationally, one end of described ratchet is articulated with on pawl axis, described pawl axis is fixed on a side of described worm gear, and described pawl axis is provided with torsion spring, only can the spacing semiaxis of one-directional rotation when coordinating described ratchet to be provided with on described power transmission shaft for making power transmission shaft energy storage, during energy storage, the end of described ratchet is resisted against the side of described spacing semiaxis, described pivot pin is fixed on a mounting panel, and coordinate the hinged end of described ratchet to arrange.
Especially, described ratchet is provided with a limited impression relative to the other end of hinged end, coordinate limited impression on the side of described worm gear, be provided with a spring pivot, when described ratchet is resisted against on described spacing semiaxis, described spring pivot is positioned at described limited impression, to make having gap between the bottom surface of this end of ratchet and described power transmission shaft.
Especially, described drive unit adopts motor, and described motor connects described worm screw by an one-way clutch.
Especially, described pawl axis outer end is provided with for carrying out spacing shaft block ring to ratchet and torsion spring.
Especially, one end of described torsion spring is connected on described worm gear, and another is connected to the hinged end of described ratchet.
Beneficial effect of the present invention is, compared with prior art not only structure is simply exquisite, volume is little for the described arrangement of clutch for switch cubicle operating mechanism; And reliable stable, be applicable to applying on a large scale.

Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of arrangement of clutch for switch cubicle operating mechanism comprises drive motors 1, worm screw 2, worm gear 3, power transmission shaft 4, ratchet 5 and pivot pin 6, the output of described drive motors is by one-way clutch 7 connecting worm 2, described worm screw 2 is meshed with described worm gear 3, described power transmission shaft 4 is arranged at the center of described worm gear 3 rotationally, one end of described ratchet 5 is articulated with on pawl axis 8, described pawl axis 8 is fixed on a side of described worm gear 3, and described pawl axis 8 is provided with torsion spring 9, described pawl axis 8 outer end is provided with for carrying out spacing shaft block ring 10 to ratchet 5 and torsion spring 9.One end of described torsion spring 9 is connected on described worm gear 3, and another is connected to the hinged end of described ratchet 5.
Only can the spacing semiaxis 11 of one-directional rotation when coordinating described ratchet 5 to be provided with on described power transmission shaft 4 for making power transmission shaft 4 energy storage.During energy storage, the end of described ratchet 5 is resisted against the side of described spacing semiaxis 11, and this end of described ratchet 5 is provided with a limited impression 12, coordinate limited impression 12 on the side of described worm gear 3, be provided with a spring pivot 13, when described ratchet 5 is resisted against on described spacing semiaxis 11, described spring pivot 13 is positioned at described limited impression 12, to make having gap between the bottom surface of this end of ratchet 5 and described power transmission shaft 4, avoids producing contact friction between the two.
Described pivot pin 6 is fixed on a mounting panel 14, and coordinating the hinged end of described ratchet 5 to arrange, described mounting panel 14 is arranged on the power transmission shaft 4 of described worm gear 3 side, after energy storage terminates, described bearing pin 6 pushes down the hinged end of described ratchet 5, then ratchet 5 overcomes the elastic force of torsion spring 9 and opens.
During work, drive motors 1 drives worm screw 2 to rotate, thus drives worm gear 3 to rotate, and now the end of ratchet 5 is resisted against the side of described spacing semiaxis 11 under the effect of torsion spring 9 elastic force, therefore the rotation of worm gear 3 drives power transmission shaft 4 one-directional rotation, thus carry out energy storage by power transmission shaft 4.After energy storage terminates, now just ratchet 5 turns to the position of pivot pin 6, and bearing pin 6 pushes down the hinged end of described ratchet 5, then ratchet 5 overcomes the elastic force of torsion spring 9 and opens.Thus the restriction lost power transmission shaft 4, power transmission shaft 4 rotates backward and carries out energy storage release.Drive motors 1 drives worm gear 4 to be rotated further by worm screw 2, and ratchet 5 rotates with worm gear 4, thus makes the hinged end of ratchet 5 cross bearing pin 6, by torsion spring 9, ratchet 5 is resetted and carries out next energy storage, releasing operation.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
