Technical field
The utility model relates to a kind of automatic switching off/on device.
Background technology
In daily production process, people need a kind of automatic switching off/on device to realize automatically opening and closing of switch usually.Existing automatic switching off/on device has two kinds of mode of operations: automatic operation mode and manual work pattern.When automatic switching off/on device was operated in automatic operation mode, described automatic switching off/on device rotated by motor driven gear, and the tooth bar engagement of described gear and a connecting valve is moved thereby drive described tooth bar, and then realizes the automatic divide-shut brake of switch.When automatic switching off/on device was operated in manual work pattern, described automatic switching off/on device drove described tooth bar and moves by manually pulling handle, and then realized the divide-shut brake of switch.But when motor has a power failure, motor can be by locked, and when realizing the divide-shut brake of switch by manual work pattern this moment, need to tooth bar move and driven gear, electric machine rotation by manually pulling, thereby so that automatically switching off/on device in situation about having a power failure, realize by manual mode that the divide-shut brake of switch becomes and hardly may.
In view of the above problems, be necessary to provide a kind of automatic switching off/on device, this automatic switching off/on device still can be realized the divide-shut brake of switch like a cork in situation about having a power failure, thereby addresses the above problem.
The utility model content
For the deficiencies in the prior art, the technical problem that the utility model solves provides a kind of automatic switching off/on device, and this automatic switching off/on device can be realized by manual mode the divide-shut brake of switch like a cork in situation about having a power failure.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of automatic switching off/on device, comprise cam orientation part, pin, mounting panel, be installed in gear, the tooth bar fixture on the described mounting panel and be installed in the described tooth bar fixture and the tooth bar that can in described tooth bar fixture, be free to slide, described cam orientation part comprises eccentric shaft and the eccentric wheel that rotates around described eccentric shaft, and described mounting panel is provided with the gap slot that matches with described eccentric wheel and the rotation hole that matches with described pin.
Further, be provided with groove on the described eccentric shaft.
Further, the sectional view of described groove is rectangular.
Further, the sectional view of described gap slot is circular arc.
Further, described tooth bar fixture is provided with the first fixing hole that matches with described pin and the second fixing hole that matches with described cam orientation part.
Further, described tooth bar fixture also is provided with to accommodate the accepting groove of described gear.
Further, the sectional view of described accepting groove is circular arc.
The beneficial effects of the utility model are: compared to prior art, automatic switching off/on device described in the utility model by eccentric wheel so that under manual work pattern described gear and described tooth bar be separated, thereby so that the operator can pull tooth bar easily, and then the drive switch opens or the closure that link to each other with described tooth bar.

Fig. 2 is the front view of the automatic switching off/on device of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Shown in please refer to the drawing 1, the automatic switching off/on device 100 of the utility model comprises cam orientation part 10, pin 20, mounting panel 30, be installed in gear 40, the tooth bar fixture 50 on the described mounting panel 30 and be installed in shown on the tooth bar fixture 50 and the tooth bar 60 that can be free to slide at described tooth bar fixture 50, described tooth bar 60 can with described gear 40 engagements.
Please refer to the drawing 1 and in conjunction with shown in Figure 2, described cam orientation part 10 comprise runner 11, eccentric wheel 12 and the eccentric shaft 13 between the edge of the center of circle of described runner 11 and described runner 11.Described eccentric wheel 12 and described eccentric shaft 13 are tangent.Be provided with groove 131 on the described eccentric shaft 13, in order to insert described groove 131 with instruments such as bottle openers, and then rotate described eccentric shaft 13.The sectional view of described groove 131 is rectangle.Described pin 20 is cylindric.Described mounting panel 30 roughly is tabular, and it is provided with the rotation hole 31 that matches with described pin 20 and the gap slot 32 that matches with described cam orientation part 10, and the sectional view of described gap slot 32 is circular arc.Described gear 40 is installed in the bottom of described mounting panel 30.The accepting groove 53 that described tooth bar fixture 50 is provided with the first fixing hole 51 that matches with described pin 20, the second fixing hole 52 that matches with described cam orientation part 10 and is used for accommodating described gear 40, the sectional view of described accepting groove 53 is circular arc.Described pin 20 passes described rotation hole 31 and described the first fixing hole 51, so that described mounting panel 30 and described tooth bar fixture 50 be fixed together, and described mounting panel 30 is rotated around described pin 20.Described cam orientation part 10 passes described gap slot 32 and is installed in described the second fixing hole 52, and the eccentric shaft 13 of described cam orientation part 10 can be in the 52 interior rotations of described the second fixing hole, and described eccentric wheel 12 and described gap slot 32 are tangent.When described cam orientation part 10 rotated, described eccentric wheel 12 was along described eccentric shaft 13 rotations and act on described gap slot 32 so that described mounting panel 30 rotates around described pin 20.Described tooth bar 60 is connected with a switch (not shown), and it is installed in the described tooth bar fixture 50, and can be free to slide in described tooth bar fixture 50.
