Abstract
The utility model relates to a strengthening assembly of an operation interlocking mechanism of a grounding switch of an electric power cabinet, which comprises a support seat and an interlocking core and is characterized in that an abnormal-shaped through hole used for the interlocking core to penetrate through is arranged on the front side of the support seat, a round through hole used for an interlocking driving shaft of the grounding switch to penetrate through is arranged on the back side of the support seat, a round sleeve is arranged on the abnormal-shaped through hole, a horizontal clamping groove is arranged on the round sleeve, the driving end of the interlocking driving shaft of the grounding switch is provided with a cavity used for arranging the interlocking core, an elastic spring used for achieving connection of the driving shaft and the interlocking core is arranged in the cavity, a horizontal clamping groove is arranged on the peripheral wall of the cavity of the driving shaft, and a protruding clamping pin used for being clamped on the horizontal clamping groove of the peripheral wall of the cavity and the horizontal clamping groove of the round sleeve is arranged on the periphery of the interlocking core. The strengthening assembly is simple in structure and capable of preventing damage to the interlocking mechanism caused by the fact that operators exert too much force, thereby ensuring safe use of the electric power cabinet.
Description
Technical field
The utility model relates to the reinforcing elements of a kind of electric power cabinet earthed switch operation interlocking mechanism, is applied to electric power cabinet earthed switch interlocking device.
Background technology
The earthed switch interlocking device of electric power cabinet is vital for fail safe, and present interlocking device comes in fact inadequately for the fail safe protection, and being overexerted by operating personnel easily causes interlocking device's loss of function.Therefore, to the problems referred to above be the object of the utility model research.
Summary of the invention
The purpose of the utility model is to provide the reinforcing elements of a kind of electric power cabinet earthed switch operation interlocking mechanism, has solved effectively that present electric power cabinet interlocking device is overexerted by operating personnel and the problem damaged helps protecting interlocking device and improves fail safe.
The utility model is characterised in that: the reinforcing elements of a kind of electric power cabinet earthed switch operation interlocking mechanism; Comprise through bolt be connected on the electric power cabinet cabinet body frame column bearing and and the interlocking core that links together with earthed switch interlocking driving shaft; It is characterized in that: the front side that said bearing is connected on the cabinet body frame column has in order to run through the special-shaped through hole of the core of interlocking; The rear side that said bearing is connected on the cabinet body frame column is provided with in order to run through the manhole of earthed switch interlocking driving shaft; Said special-shaped through hole is provided with circular sleeve; Offer a word draw-in groove on the said circular sleeve, the drive end of said earthed switch interlocking driving shaft is provided with in order to install the cavity of interlocking core, is provided with the elastic pressuring spring in order to realize that driving shaft and interlocking core link together in the said cavity; Begin to have a word draw-in groove on the cavity perisporium of said driving shaft, the periphery of said interlocking core is provided with in order to be connected to the protuberance bayonet lock on cavity perisporium one word draw-in groove and the circular sleeve one word draw-in groove.
The advantage of the utility model: the utility model is simple in structure, can prevent effectively that operating personnel from overexerting to cause the generation of interlocking device's damaged condition, thereby ensure the safe handling of electric power cabinet.
Description of drawings
Fig. 1 is the utility model example structure sketch map.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment
With reference to figure 1 and Fig. 2; The reinforcing elements of a kind of electric power cabinet earthed switch operation interlocking mechanism; Comprise through bolt 1 be connected on the electric power cabinet cabinet body frame column 2 bearing 3 and and the interlocking core 5 that links together with earthed switch interlocking driving shaft 4; The front side that said bearing 3 is connected on the cabinet body frame column 2 has in order to run through the special-shaped through hole 3-1 of the core 5 of interlocking; The rear side that said bearing 3 is connected on the cabinet body frame column 2 is provided with in order to run through the manhole 3-2 of earthed switch interlocking driving shaft 4; Said special-shaped through hole 3-1 is provided with circular sleeve 6; Offer a word draw-in groove on the said circular sleeve 6, the drive end of said earthed switch interlocking driving shaft 4 is provided with in order to install the cavity 4-1 of interlocking core 5, is provided with the elastic pressuring spring 7 in order to realize that driving shaft 4 and interlocking core 5 link together in the said cavity 4-1; Begin to have a word draw-in groove 4-2 on the cavity 4-1 perisporium of said driving shaft 4, the periphery of said interlocking core 5 is provided with in order to be connected to the protuberance bayonet lock 5-1 on cavity 4-1 perisporium one word draw-in groove 4-2 and the circular sleeve 6 one word draw-in grooves.
The front end of above-mentioned interlocking core 5 is provided with L shaped latch hook 5-2.
Above-mentioned earthed switch interlocking driving shaft 4 is positioned at bearing 3 outer perimembranous and is provided with through the stop collar 9 of holding screw locking 8 on driving shaft 4.
The perimembranous that above-mentioned earthed switch interlocking driving shaft 4 is positioned at bearing 3 is provided with the annulus 10 that wraps interlocking core 5.
Practical implementation process: when this device snaps in the word draw-in groove on the circular sleeve of bearing rear side at the interlocking core; Whole interlocking device can't operate; Have only when the pass, back door and close; And promote elastic pressuring spring through the interlocking core in the bearing and break away from draw-in groove, rotating driveshaft is accomplished further operation process again.This device has in use been set up draw-in groove and protuberance bayonet lock interlocking core on of bearing and earthed switch interlocking on the driving shaft, and the equipment that effectively prevented answers operating personnel to overexert and the generation of the damage problem that causes.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
