Specifically, the front surface of the sliding plate 3 is fixedly connected with a stop pillar, and the first shifting plate 6 can be extruded with the stop pillar. The catch allows the second paddle 10 to more stably depress the travel switch 8.
Specifically, a rotating rod 16 is rotatably connected to the bottom plate 1, a first connecting lever 9 and a second connecting lever 15 are fixedly connected to the outer wall of the rotating rod 16, a sliding rod is fixedly connected to one side, away from the rotating rod 16, of the first connecting lever 9, a long hole is formed in the front face of the first shifting plate 6, and the sliding rod is slidably connected in the long hole to enable the first shifting plate 6 to stably move horizontally left and right;
the second crank arm 15 is matched with a tripping head of the circuit breaker and used for enabling the second shifting plate 10 to shield the mounting opening of the operating shaft 13 when the circuit breaker is tripped. When the circuit breaker tripping operation, the jump head of tripping operation can extrude second connecting lever 15 to make the action of second connecting lever 15, thereby make dwang 16 rotate, pivoted dwang 16 drives first connecting lever 9 and rotates, and the cooperation of rethread slide bar and rectangular hole makes first group board 6 remove, and first group board 6 drives the second and dials board 10 and removes and block operation shaft 13 installing port, makes electric potential notch 2.1 can not the circular telegram. Here too, it is made more clear for the person that the circuit breaker has tripped. Prevent that personnel from not understanding the electrical apparatus, lead to damaging the device, the fool-proof structure of setting.
Specifically, an indication output shaft 17 is fixedly arranged on the front surface of the turntable 2. The person can rotate the turntable 2 conveniently.
Specifically, one side of the sliding plate 3 close to the turntable 2 is provided with an arc-shaped groove. The arc-shaped slot enables the turntable 2 to rotate without causing frictional damage to the slide plate 3.
And the indicating output shaft 17 is fixedly connected with a first gear, the bottom plate 1 is rotatably connected with a disc, the axis of the disc is fixedly connected with a cylinder, the outer wall of the cylinder is fixedly connected with a second gear, the first gear and the second gear are meshed with each other, one side of the disc, away from the cylinder, is eccentrically and fixedly connected with an action rod, and the action rod can drive articles such as a door body outside the machine to act, so that the device realizes interlocking.
In this embodiment, when a person needs to change a connection station, the power supply of the device is turned on by using the operating handle 18, then the rotating disc 2 is rotated, the outer wall of the rotating disc 2 is pressed by the sliding plate 3 at this time due to the elastic force of the second spring 5, then the rotating disc 2 is continuously rotated, the reset poking plate 2.5 is poked by the extending plate of the sliding plate 3, then the sliding plate 3 is squeezed into the potential slot 2.1 under the elastic force of the second spring 5, and at this time, the sliding plate 3 and the potential slot 2.1 are connected in a potential mode. And at this moment, the sliding plate 3 moves a certain distance leftwards under the elasticity of the second spring 5, the clamping plate 12 loses the constraint of the sliding plate 3, and the bottom of the clamping plate 12 is inserted into the groove of the operating handle 18 under the acting force of the third spring to lock the operating handle 18. At this time, the turntable 2 and the operating handle 18 are locked. The self-locking effect is generated. The structure is simple and easy to implement, and the self-locking difficulty is greatly simplified. And when the device is connected at the adjusting station, the device can automatically self-lock only by rotating the turntable by hand. Compared with the similar device, the device has a simpler and more ingenious structure and has remarkable progress.
When the station is replaced, the self-locking effect of the station of the device can be relieved by only poking the sliding plate 3 by hands, the specific steps are as follows, the sliding plate 3 is poked rightwards manually, the locking effect of the operating handle 18 is relieved by the sliding plate 3, the reset poking plate 2.5 returns to the initial position at the moment, the reset poking plate 2.5 supports the sliding plate 3, so that the sliding plate 3 cannot be inserted into the potential notch 2.1 for potential connection, then the rotary disc 2 continues to rotate, and then the principle is the same as that of the above, the sliding plate 3 automatically enters the next notch station for potential connection.
Under the normal condition, under the action of the fourth spring 7, the second shifting plate 10 automatically moves leftwards, at the moment, the second shifting plate 10 can trigger the travel switch 8, the power supply of the electric circuit is turned off by transmitting signals, namely, under the normal condition, the signal of the travel switch 8 can turn off the electric power supply switch, and the safety of connection of the potential of personnel in manual operation change is greatly guaranteed. And at this moment, normal state, operating axis 13 exposes, can open or close the power of artifical electric potential, the manual operation of being convenient for.
However, in order to avoid that the operator operates the connection for changing the potential even when the automatic power supply of the apparatus is turned on, it is necessary to disable the operator from connecting for changing the potential. The concrete action is as follows, when the circuit breaker is closing, the switch of circuit breaker can come out this moment, and the switch that comes out can make dwang 16 rotate under the cooperation of second connecting lever 15, and pivoted dwang 16 makes first connecting lever 9 rotate, and first connecting lever 9 is through the slide bar on it, and rectangular hole of deuterogamying makes first group board 6 remove to right to make second group board 10 blocked operation shaft 13, make personnel can't open the power of manual station. The safety of personnel is greatly guaranteed.
The technical scope of the present invention is not limited to the above description, and those skilled in the art can make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and such changes and modifications should fall within the protective scope of the present invention.
