It is preferred that, the quantity of first contact is two groups, and two group of first contact is vertically set, described first Contact is consistent with the structure of the second contact.

It is preferred that, the quantity of the conductive bar is two groups, and two groups of conductive bars are vertically set, between two groups of conductive bars Distance it is consistent with the distance between two group of first contact.

It is preferred that, the radio-frequency module by wire respectively with the first contact and the second contact portion.

It is preferred that, the two ends of the power coil are connected with two groups of conductive bars respectively.

It is preferred that, the radio-frequency module uses model RFM22B radio-frequency module.

The beneficial effects of the utility model：

1st, by the push rod in setting, triggering disk, screwed hole, the first contact and the second contact, push rod push-and-pull shape is realized The signal triggering of state, using the difference for the direction of rotation for triggering disk, makes the first contact and the second contact be carried out respectively with conductive bar Contact, forms push rod push-and-pull status signal；

2nd, by the insulating cylinder of setting, power coil, permanent magnets, conductive bar and radio-frequency module, using power coil and forever Magnetic patch charges to radio-frequency module, so that the motion state signal of radio-frequency module transmission signal push rod, the design operation is simple, no Need external power source to access, the motion state of push rod is judged in time, the high cost of practicality is low.

Brief description of the drawings

Fig. 2 be the utility model proposes a kind of self power generation key switch and receiving device sectional view.

In figure：1 housing, 2 insulating cylinders, 3 power coils, 4 push rods, 5 platens, 6 permanent magnets, 7 triggering disks, 8 screwed holes, 9 the One contact, 10 radio-frequency modules, 11 conductive bars, 12 second contacts.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.

Reference picture 1-2, a kind of self power generation key switch and receiving device include the housing 1 of hollow structure, and housing 1 is circle Column construction, the inside coaxial line of housing 1 is provided with insulating cylinder 2, and the lateral wall of insulating cylinder 2 is wound with power coil 3, insulating cylinder 2 internal slide is connected with push rod 4, and one end that push rod 4 stretches out housing 1 is vertically welded with platen 5, the outside fixed cover of push rod 4 Cylindrical magnet block 6 is connected to, the underface of permanent magnets 6 is rotatably connected to triggering disk 7, and the top of triggering disk 7 is offered and push rod 4 The screwed hole 8 of threaded connection, the lateral wall of triggering disk 7 is respectively welded the first contact 9 and the second contact 12, and the first contact 9 Set with the second contact 12 along the triggering axisymmetrical of disk 7, the inner ring of insulating cylinder 2 is stained with circular arc conductive bar 11, triggering disk 7 Inside is inlaid with radio-frequency module 10.

The quantity of first contact 9 is two groups, and two group of first contact 9 is vertically set, and the first contact 9 and second is touched The structure of point 12 is consistent, and the quantity of conductive bar 11 is two groups, and two groups of conductive bars 11 are vertically set, two groups of conductive bars 11 it Between distance it is consistent with the distance between two group of first contact 9, radio-frequency module 10 by wire respectively with the first contact 9 and second Contact 12 is connected, and the two ends of power coil 3 are connected with two groups of conductive bars 11 respectively, and radio-frequency module 10 is using model RFM22B's Radio-frequency module.
