Utility model content
The purpose of this utility model is in that to provide a kind of arrangement of clutch for switch cubicle operating mechanism, and it has simple in construction, the little and reliable stable feature of volume, to solve the problems referred to above existed in prior art for the arrangement of clutch of switch cubicle operating mechanism。
For reaching this purpose, this utility model by the following technical solutions:
A kind of arrangement of clutch for switch cubicle operating mechanism, it includes driving device, worm screw, worm gear, power transmission shaft, ratchet and pivot pin, wherein, the outfan connecting worm of described driving device, described worm screw is meshed with described worm gear, described power transmission shaft is rotatablely arranged at the center of described worm gear, one end of described ratchet is articulated with on pawl axis, described pawl axis is fixed on the one side of described worm gear, and described pawl axis is provided with torsion spring, described ratchet is coordinated when being provided with on described power transmission shaft for making power transmission shaft energy storage, to be only capable of the spacing semiaxis of one-directional rotation, during energy storage, the end of described ratchet is resisted against the side of described spacing semiaxis, described pivot pin is fixed on an installing plate, 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, limited impression is coordinated to be provided with a resilient key on the side of described worm gear, when described ratchet is resisted against on described spacing semiaxis, described resilient key is positioned at described limited impression, so that having gap between the bottom surface of this end of ratchet and described power transmission shaft。
Especially, described driving device adopts motor, and described motor connects described worm screw by an one-way clutch。
Especially, described pawl axis outer end is provided with for ratchet and torsion spring are carried out spacing shaft block ring。
Especially, one end of described torsion spring is connected on described worm gear, and another is connected to the hinged end of described ratchet。
The beneficial effects of the utility model are, compared with prior art to be not only simple in structure exquisiteness, volume little for the described arrangement of clutch for switch cubicle operating mechanism；And reliable stable, it is suitable for large-scale popularization and application。

Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention。
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of arrangement of clutch for switch cubicle operating mechanism includes drive motor 1, worm screw 2, worm gear 3, power transmission shaft 4, ratchet 5 and pivot pin 6, the outfan of described drive motor passes through one-way clutch 7 connecting worm 2, described worm screw 2 is meshed with described worm gear 3, described power transmission shaft 4 is rotatablely arranged at the center of described worm gear 3, one end of described ratchet 5 is articulated with on pawl axis 8, described pawl axis 8 is fixed on the one 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 ratchet 5 and torsion spring 9 are carried out spacing shaft block ring 10。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。
Described ratchet 5 is coordinated when being provided with on described power transmission shaft 4 for making power transmission shaft 4 energy storage, to be only capable of the spacing semiaxis 11 of one-directional rotation。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, limited impression 12 is coordinated to be provided with a resilient key 13 on the side of described worm gear 3, when described ratchet 5 is resisted against on described spacing semiaxis 11, described resilient key 13 is positioned at described limited impression 12, so that having gap between the bottom surface of this end of ratchet 5 and described power transmission shaft 4, it is to avoid produce contact friction between the two。
Described pivot pin 6 is fixed on an installing plate 14, and coordinating the hinged end of described ratchet 5 to arrange, described installing plate 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 to open。
During work, drive motor 1 drives worm screw 2 to rotate, thus driving worm gear 3 to rotate, 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, carries out energy storage thereby through 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 to open。Thus losing the restriction to power transmission shaft 4, power transmission shaft 4 rotates backward and carries out energy storage release。Drive motor 1 drives worm gear 4 to be rotated further by worm screw 2, and ratchet 5 rotates with worm gear 4, so that the hinged end of ratchet 5 crosses bearing pin 6, makes ratchet 5 reset by torsion spring 9 and carries out next energy storage, release operation。
Above example simply elaborates ultimate principle of the present utility model and characteristic; this utility model is not limited by above-mentioned example; under the premise without departing from this utility model spirit and scope; this utility model also has various change and change, and these changes and change both fall within the scope of claimed this utility model。This utility model claims scope and is defined by appending claims and equivalent thereof。
