Abstract

The utility model discloses a dual-purpose incandescent bulb base of supporting-tube shape for both spigot and screw socket bulbs. The dual-purpose incandescent bulb base is characterized in that the ring of the screw socket and the spigot bulb are connected together as one, the position and the shape between the two recoiling electrodes are changed properly and an insulation pole is installed between the two recoiling electrodes of the incandescent bulb base which suits both spigot and screw socket bulbs. The utility model has the advantages of reasonable design and overcoming the defect of a bulb base only holding the corresponding bulb.

Description

Dual-purpose incandescent lamp base for both screw socket bulb and spigot bulb

The utility model relates to a kind of lamp socket that supports spot.

Two kinds of connected mode current tap, the screw sockets of existing incandescent lamp and lamp socket.It is firm that screw lamp holder has contact, the advantage that the amount of damming is big, and then process structure is simple, easy to use, consumptive material is few for plug adapter, therefore, he generally is used for domestic lighting and industrial light for it, but because two kinds of lamp sockets can only use corresponding bulb, this limitation is brought a lot of inconvenience.Be spoilt as certain lamp, must replace with similar bulb, otherwise can't throw light on.

The purpose of this utility model is can only improve with the defective that corresponding bulb is used at preceding two kinds of lamp sockets, designs a kind of socket, screw socket Two-purpose lampstand.

The design of this Two-purpose lampstand is as follows:

Former screw socket lamp ring and socket lamp ring are fused, form the disjunctor lamp ring, make it to have the dual-use function that can adapt to socket, screw-socket bulb.Design to lamp holder electrode is, two elasticity of existing plug adapter are pressed interelectrode distance and profile is done suitable change, one of them electrode as common electrode, is made it to adapt to an electrode of socket bulb, can adapt to the apex electrode of screw-socket bulb again; The lower end contact of another electrode is the inclined-plane towards the one side of lamp socket center, claim the inclined-plane electrode, aim at the socket bulb design, it can also avoid this electrode to be withstood by the glass insulation circle around the screw-socket bulb apex electrode, the upper end of inclined-plane electrode and power supply contact pin disconnect at ordinary times, an insulated column that energy is up and down is housed in the middle of common electrode and the inclined-plane electrode, and the elastic contact blade that its upper end is communicated with the disjunctor lamp ring is being pressed, and elastic contact blade also disconnects at ordinary times with power supply contact pin.When putting into screw-socket bulb, the screw-socket bulb apex electrode withstands common electrode simultaneously and insulated column up moves, make elastic contact blade and power supply contact pin connect, electric current forms the loop by common electrode, filament, disjunctor lamp ring, elastic contact blade, power supply contact pin and outside line, at this moment, because of residing position of inclined-plane electrode and inclined-plane reason, do not move, only contact with the glass insulation circle on screw-socket bulb top, thereby maintenance and power-off state, back off behind the screw-socket bulb, elastic contact blade and power supply contact pin disconnect, and insulated column is pushed back original position.When inserting socket bulb, an electrode of bulb withstands common electrode, and another electrode withstands the inclined-plane electrode and up moves, and connects and the formation loop with power supply contact pin, at this moment, although it is mobile that insulated column up has,, elastic contact blade still is in power supply contact pin disconnects shape because of displacement is not enough, therefore, the disjunctor lamp ring is non-conductive, behind the socket bulb of backing off, and common electrode and inclined-plane electrode return.

Two-purpose lampstand of the present utility model is safe and reliable, has both adapted to socket bulb, adapts to screw-socket bulb again, has solved because of lacking certain bulb and has caused the problem that can not throw light on.

An embodiment of the present utility model now is described in detail in detail in conjunction with the accompanying drawings:

Fig. 1 is the structure chart of Two-purpose lampstand of the present utility model;

Fig. 2 is the vertical view after the utility model Two-purpose lampstand is got lid;

Fig. 3 is the upward view of the utility model Two-purpose lampstand.

With reference to Fig. 1, this Two-purpose lampstand comprises lamp holder shell ［ 1 ］, cap ［ 2 ］, connects lamp ring ［ 3 ］, common electrode ［ 4 ］, inclined-plane electrode ［ 5 ］, insulated column ［ 6 ］, elastic contact blade ［ 7 ］, power supply contact pin ［ 8 ］, common electrode binding post ［ 9 ］, power-line terminal ［ 10 ］.Common electrode ［ 4 ］ and inclined-plane electrode ［ 5 ］ all put return spring ［ 11 ］, disjunctor lamp ring ［ 3 ］ is opened one " L " shape socket groove ［ 12 ］, being convenient to socket bulb inserts, insulated column ［ 6 ］ upper end is being pressed by elastic contact blade ［ 7 ］, and elastic contact blade ［ 7 ］ and inclined-plane electrode ［ 5 ］ all are the disconnection shape at ordinary times with power supply contact pin ［ 8 ］.

With reference to Fig. 2, Fig. 3, power supply contact pin ［ 8 ］ strikes out one with power-line terminal ［ 10 ］, is rotated with on lamp holder shell ［ 1 ］ with screw ［ 13 ］, and spins with disjunctor lamp ring ［ 3 ］ insulation; Common electrode binding post ［ 9 ］ has an insulation shelves link stopper ［ 14 ］ on every side, and two binding posts all are to be connected with outside line by screw ［ 15 ］; Elastic contact blade ［ 7 ］ is to be rotated with on lamp holder shell ［ 1 ］ by screw ［ 16 ］ to be communicated with being connected lamp ring ［ 3 ］.
