Abstract
The utility model relates to a kind of electric ground switch of belt sensor, comprise support, it is characterized in that: described support is provided with a V-type axle, described V-type axle is provided with the moving knife that can rotate around V-type axle, described support side is provided with erection column, a fixed contact is stretched out in described erection column upper end, and described erection column is provided with transducer, and the blade of described moving knife is provided with time transducer.After adopting above technical scheme: V-type axle drives moving knife to rotate, and moving knife is provided with time transducer, when moving knife turn to moving knife contact with fixed contact time, then earthed switch can be connected, and changes the pattern of motorized motions into.
Description
Technical field
The utility model belongs to earthed switch, specifically belongs to a kind of electric ground switch of belt sensor.
Background technology
Earthed switch is used for the Purely mechanical switch of circuit ground part, belong to isolating switch classification, it can carry the electric current (such as short circuit current) under non-normal condition within a certain period of time, but do not require the electric current under its carrying normal circuit condition, but how to be incorporated in the earthed switch of pure machinery by electronic, just to need very complicated structure.
Summary of the invention
Technical problem to be solved in the utility model is: the electric ground switch providing a kind of belt sensor.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of electric ground switch of belt sensor, comprise support, it is characterized in that: described support is provided with a V-type axle, described V-type axle is provided with the moving knife that can rotate around V-type axle, described support side is provided with erection column, a fixed contact is stretched out in described erection column upper end, and described erection column is provided with transducer, and the blade of described moving knife is provided with time transducer.
Spring base is provided with between described support and V-type axle.
After adopting above technical scheme: V-type axle drives moving knife to rotate, and moving knife is provided with time transducer, when moving knife turn to moving knife contact with fixed contact time, then earthed switch can be connected, and changes the pattern of motorized motions into.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, a kind of electric ground switch of belt sensor, comprises support 1, described support 1 is provided with a V-type axle 2, described V-type axle 2 is provided with the moving knife 3 that can rotate around V-type axle 2, and described support 1 side is provided with erection column 4, and a fixed contact 5 is stretched out in described erection column 4 upper end, described erection column 4 is provided with transducer 6, the blade of described moving knife 3 is provided with time transducer 7, is provided with spring base 8, in Fig. 1 between support 1 and V-type axle 2, moving knife 3 has two location statuss, i.e. a solid line and dotted line.
After adopting above technical scheme: V-type axle drives moving knife to rotate, and moving knife is provided with time transducer, when moving knife turn to moving knife contact with fixed contact time, then earthed switch can be connected, and changes the pattern of motorized motions into.
