Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The embodiment is as follows:
referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a fall switch convenient to open and close a floodgate, includes insulating cylinder 1, the downside all is provided with mount pad 2 on the outer wall of insulating cylinder 1, the downside 2 right sides of mount pad rotate through the round pin axle and install support 6, be provided with insulating tube 7 on the support 6, the upside 2 right sides of mount pad are connected with conducting rod 3, the right-hand member of conducting rod 3 is provided with electrically conductive card cover 4, electrically conductive card cover 4 is the cavity shape, and electrically conductive card cover 4's lower surface and right side wall lower part seted up opening 5, the bottom of insulating tube 7 can be dismantled and be connected with down terminal 8, the inner chamber of insulating tube 7 is provided with spiral fuse 9, the lower extreme and the down terminal 8 of spiral fuse 9 are connected, the top of insulating tube 7 is rotated through the round pin axle and is connected with electrically conductive pendulum rod 10, the lower surface left side of electrically conductive pendulum rod 10 is connected with the upper end of spiral fuse 9 through terminal 11, be connected through elastic component 12 between the lower surface left end of electrically conductive pendulum rod 10 and the top left side of insulating tube 7.
And a conductive ball is arranged at the right end of the conductive oscillating bar 10. Through the setting of electrically conductive ball, reduce the friction, and do not influence the contact electrically conductive. The insulating cylinder 1 and the insulating tube 7 are made of ceramic materials. The right side wall of the insulating tube 7 is provided with a push-pull ring 13.
The working principle is as follows: when in use, the lower wiring column 8 and the conducting rod 3 are respectively connected with two wiring ends to be connected.
The upper end of the spiral fuse wire 9 is connected with the wiring terminal 11, then the spiral fuse wire 9 is pulled down, the conductive swing rod 10 rotates anticlockwise, the bottom end of the spiral fuse wire 9 is fixed through the lower wiring terminal 8, and the elastic piece 12 is in a contraction state under the tensioning effect of the spiral fuse wire 9.
