Abstract
The utility model discloses a bolt-type magnetic induction switch comprising a bolt and a nut, wherein the bolt and the nut are respectively made from a conductive non-magnetic material, a blind hole is drilled in the center (inward a screw) of the head of the bolt, the magnetic induction switch is encapsulated by an encapsulating material in the blind hole, another blind hole is also drilled in the center (inward the screw) of a screw end of the bolt, a nut is a blind hole nut, a permanent magnet is axially fixed in the center of the blind hole nut, the distance between the blind holes at two ends of the bolt is required to guarantee triggering of the permanent magnet to the magnetic induction switch, and the magnetic induction switch is triggered after the nut and the bolt are assembled together in a rotating manner. The bolt-type magnetic induction switch disclosed by the utility model can timely acquire a signal and can transmit the signal to a monitor in a process that stealing is performed by a thief.
Description
Technical field
The utility model relates to a kind of switch, especially a kind of screw bolt-type magnetic switch.
Background technique
In power supply system, the stolen phenomenon of distribution transformer happens occasionally.Stolen in order to prevent distribution transformer, people have designed and can only precession can not revolve the anti-theft bolt that moves back.Because the appearance of miniature gas cutting device, the burglar uses miniature gas cutting device to be easy to just anti-theft bolt to be destroyed, and in fact, anti-theft bolt can not stop the burglar to steal transformer.So, stop that transformer is stolen also must and to be passed in real time the regulator with the signal of collection by the collection of stolen signal and realize.Whole theft transformer must at first be turned on the bolt of stationary transformer, open transformer cover theft transformer core and must at first turn on the bolt of stationary transformer lid, hence one can see that, and the burglar being turned on or destroys bolt is the most timely as the stolen signal of transformer.Therefore, designing a kind of screw bolt-type magnetic switch, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of screw bolt-type magnetic switch.
The technical scheme in the invention for solving the technical problem is:
The screw bolt-type magnetic switch, formed by screw bolt and nut, described screw bolt and nut is the conduction non-magnet material and makes, head center at bolt is drilled with blind hole in screw rod, in this blind hole, be packaged with magnetic switch with potting material, in the screw rod end of bolt, also be drilled with blind hole in the mind-set screw rod, nut is grommet nut, at the central shaft of grommet nut to being fixed with permanent magnet, distance between the blind hole at bolt two ends should guarantee that permanent magnet is to the triggering of magnetic switch, when nut and bolt spinning together after, magnetic switch triggers.Described magnetic switch is for often opening magnetic switch, normally closed magnetic switch or normally-open normally-close conversion hysteria magnetic switch.
Preferably, described potting material is silica gel or epoxy resin.
Preferably, described grommet nut comprises the through hole nut that the conduction non-magnet material is made, and shutoff is by one section general steel plate in the screw of nut, and permanent magnet and general steel plate are fixed by magnetic force.
The beneficial effects of the utility model are also to pass in real time the regulator by timely collection signal in the middle of the process that the burglar implements to steal, and easy for installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The screw bolt-type magnetic switch, formed by bolt 3 and nut 5, described bolt 3 and nut 5 are the conduction non-magnet material and make, head center at bolt 3 is drilled with blind hole in screw rod, in this blind hole, be packaged with magnetic switch 2 with potting material 1, in the screw rod end of bolt 3, also be drilled with blind hole in the mind-set screw rod, nut 5 is grommet nut, at the central shaft of grommet nut to being fixed with permanent magnet 4, distance between the blind hole at bolt two ends should guarantee the triggering of 4 pairs of magnetic switches 2 of permanent magnet, when nut 5 and bolt 3 spinnings together after, magnetic switch 2 triggers.
Described potting material 1 is silica gel or epoxy resin.
Described grommet nut comprises the through hole nut that the conduction non-magnet material is made, and shutoff is by one section general steel plate 6 in the screw of nut, and permanent magnet 4 and general steel plate 6 are fixed by magnetic force.
Described magnetic switch 2 is for often opening magnetic switch, normally closed magnetic switch or normally-open normally-close conversion hysteria magnetic switch.
