Embodiment
As shown in Figure 1, the utility model provides a kind of internal conversion device of change over switch, comprise fixed head 3, motor, left swing arm 2, right swing arm 1, transducer 5, described motor, left swing arm 2, right swing arm 1, transducer 5 all are located on the described fixed head 3, described motor is provided with motor rotating disk 12, described motor rotating disk 12 is provided with thrust unit 10, described left swing arm 2, right swing arm 1 are symmetricly set in the both sides of described thrust unit 10, described transducer 5 is two, and the symmetrical top of being located at described left swing arm 2 and right swing arm 1.Owing to adopting technique scheme, when the road power supply that uses breaks down can not normal power supply the time, driven by motor motor rotating disk 12 rotates, thereby driving thrust unit 10 rotates, then the thrust unit 10 left swing arms 2 of promotion and right swing arm 1 move in the opposite direction, then left swing arm 2 or right swing arm 1 will drive one road spring 16 and contact (simultaneously with corresponding contact 6, the spring 16 on another road disconnects with corresponding contact 6), corresponding transducer obtains signal, then control corresponding one road disconnecting link closed (another road disconnecting link disconnects), be the load continued power.
Further, be fixation of sensor 5, described transducer 5 is connected with fixed head 3 by support 4.
Further, described transducer 5 comprises contact 6 and spring 16.Contacting for transducer 5 signal be provided by contact 6 and spring 16.
Further, described thrust unit 10 is provided with two pushing blocks 11.Drive respectively left swing arm 2 and 1 motion of right swing arm.
Further, described pushing block 11 is cylinder, and pushing block 11 is stressed more even like this.
Further, described pushing block 11 is fixed on the motor rotating disk 12 by screw 15, easy disassembly.
Further, be equipped with two chutes 7 on described left swing arm 2 and the right swing arm 1, be convenient to left swing arm 2 and 1 slip of right swing arm, and the limited location function.
Further, described left swing arm 2 and right swing arm 1 are fixed on the fixed head 3 movably by pin 14.
Further, be equipped with block 9 and groove 8 on described left swing arm 2 and the right swing arm 1, block 9 is used for thrust unit 10 is positioned, and groove 8 is used for cooperating pushing block 11 to promote.
Further, described fixed head 3 is provided with fixing hole 13, is used for the fixing of fixed head.
The course of work of this example: when the road power supply that uses breaks down can not normal power supply the time, driven by motor motor rotating disk 12 rotates, thereby driving thrust unit 10 rotates, then the thrust unit 10 left swing arms 2 of promotion and right swing arm 1 move in the opposite direction, then left swing arm 2 or right swing arm 1 will drive one road spring 16 and contact (simultaneously with corresponding contact 6, the spring 16 on another road disconnects with corresponding contact 6), corresponding transducer obtains signal, then control corresponding one road disconnecting link closed (another road disconnecting link disconnects), be the load continued power, simultaneously, motor stops operating.
