Abstract
The utility model relates to an isolation automatic change-over switch with stable energy storage and energy releasing. The isolation automatic change-over switch is characterized in that the isolation automatic change-over switch comprises an upper cover, a middle spacing plate, a cantilever, an energy storage spring and a rotating shaft connected with the cantilever and the energy storage spring. One end of the energy storage spring is clamped and embedded in a groove of the upper cover and the other end is inserted in a circle groove of a rotation arm end of the rotating shaft. A boss capable of preventing the end of the energy storage spring from flipping is mounted on the middle spacing plate opposite to a break angle position of the end of the energy storage spring which is clamped and embedded in the groove of the upper cover. Because the boss is added to the middle spacing plate opposite to a fulcrum position of the energy storage spring provided by the utility model, the middle spacing plate can press the flipping end of the spring when the energy storage spring rotates in a spring axle-centered manner. Instant clamping and stumbling are prevented when a mechanism in an energy releasing state and switch breaking capacity is beneficial to be raised.
Description
Technical field
The utility model belongs to a kind of automatic change-over, particularly relates to a kind of accumulation of energy and releases the stable isolated automatic change-over of energy.
Background technology
Energy-storaging spring play between loam cake and dividing plate in present known isolated automatic change-over occurs when causing mechanism's disjunction blocking the phenomenon of stumbling, and has reduced the breaking capacity of switch.
Summary of the invention
The utility model provides a kind of accumulation of energy that prevents that energy-storaging spring from being scurried out by an end in the groove of loam cake to release the stable isolated automatic change-over of energy for solving the technical problem that exists in the known technology.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: include loam cake, central dividing plate, cantilever, energy-storaging spring and the rotating shaft that is connected with energy-storaging spring with described cantilever; One end inlay card of described energy-storaging spring is in a groove of described loam cake, the other end inserts in the circular groove of pivoted arm end of described rotating shaft, on the described central dividing plate of facing mutually at the knuckle place of the energy-storaging spring of an end in the groove of described energy-storaging spring inlay card at described loam cake, a boss that can prevent that this end of described energy-storaging spring from scurrying out is arranged.
Advantage and the good effect that the utlity model has are: because a fulcrum place with respect to energy-storaging spring has increased a boss on central dividing plate, make energy-storaging spring central dividing plate when rotating as the axle center take it can suppress spring play end, anti-locking mechanism instantaneous card occurs when releasing energy stumbles, and is conducive to improve the breaking capacity of switch.
Description of drawings
Fig. 1 is the cutaway view of one of them execution switch of isolated automatic change-over;
Fig. 2 is the front view that Fig. 1 removes loam cake.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
As shown in Figure 1, 2, energy-storaging spring 4 has a support end 2 in the groove of loam cake 1, another support end 5 is being connected with energy-storaging spring in the circular groove of the rotating shaft 6 that is connected with cantilever 10, and a spring knuckle end 3 that links to each other with support end 2 of energy-storaging spring 4 leans against on the boss 7 of central dividing plate 8.Owing to increased boss 7 at central dividing plate 8, the support end 2 that has effectively prevented energy-storaging spring 4 is scurried out from the groove of loam cake 1 and is driven slide block 9 that moving contact rack moves and block mutually and stumble.
Claims (1)
- An accumulation of energy release can be stable isolated automatic change-over, include loam cake, central dividing plate, cantilever, energy-storaging spring and the rotating shaft that is connected with energy-storaging spring with described cantilever; One end inlay card of described energy-storaging spring is in a groove of described loam cake, the other end inserts in the circular groove of pivoted arm end of described rotating shaft, it is characterized in that: on the described central dividing plate of facing mutually at the knuckle place of the energy-storaging spring of an end in the groove of described energy-storaging spring inlay card at described loam cake, a boss that can prevent that this end of described energy-storaging spring from scurrying out is arranged.
