Abstract

The utility model discloses a lamp holder for ordinary incandescent lamps, which comprises a lamp holder cover, a lamp holder body, binding posts and electrodes, wherein an inner sleeve capable of sliding is arranged in the lamp holder body. The inner wall of the inner sleeve is provided with a lamp bulb locking device, and an inner sleeve positioning device is arranged above the inner sleeve. When a lamp bulb is installed, a lamp cap is inserted into the inner sleeve and is then pushed upward. When the lamp bulb is in position, the positioning device clamps the inner sleeve. Meanwhile, the locking device on the inner wall of the inner sleeve also clamps the lamp bulb. When replacing the lamp bulb, people only need to push the inner sleeve upward, and then the lamp bulb can be taken off with much convenience. The utility model overcomes the defects that the installation time of the existing turnbuckle lamp bulb is long, and the lamp bulb can not be conveniently installed in a narrow space.

Description

A kind of ordinary incandescent lamp socket

The utility model relates to a kind of lighting device, particularly relates to a kind of ordinary incandescent lamp socket.

In the prior art, ordinary incandescent lamp socket commonly used has two kinds, a kind of is bayonet type, another kind is the screw button, and bayonet type is inactive substantially, and the thread socket that generally uses, this socket in use has the following disadvantages: (1) is installed and is exchanged inconvenience for, and use duration, particularly the narrow and small place in the space is difficult for installing exchanging for especially; (2) upgrade the broken bulb inconvenience.If the bulb fragmentation is put the lamp head split pole of staying in the socket and is difficult for taking out; (3) useful life is short.Former socket adopts spring leaf as electrode contact, is oppressed for a long time and is heated, and its elasticity is weakened and to produce contact unreal, and influence is used.

The purpose of this utility model is at the deficiencies in the prior art, and a kind of ordinary incandescent lamp socket is provided, and this socket installs that to exchange bulb for extremely convenient, is not subjected to that the space is narrow and small to be influenced, and the time spent is short, and can increase the service life.

This novel purpose can reach by following measure, this novel socket lid that comprises, the socket body, binding post and positive contact, it is characterized in that being provided with in the socket body one and slidably overlap 9 in the gear shape, and be equally spaced wavy spring sheet 11 and Spring Card 10, interior cover top is provided with positive source contact 8, cover guide runner 16 linked to each other with binding post 2 in this contact passed, both sides also are provided with two boss 5 above interior cover, between boss and interior cover, be provided with back-moving spring 6, and also be provided with pressing plate 4 between two boss, pressing plate is provided with positioning spring card 3, and the dop of this positioning spring card can slide in the special-shaped chute 17 on being located at slide block 16.

Above-mentioned Spring Card 10 is a saucerspring, and is arranged with three, lays respectively between socket body 7 and the interior cover 9, wherein stretches out in the oblique chute 15 that an end of Spring Card 10 is offered from the side of interior cover profile of tooth concave surface.

Above-mentioned positioning spring card 3 is a side direction torsion, and the bottom land of chute 17 is made up of several sections different grooves of the depth, so that positioning spring card 3 keeps in chute counterclockwise or clockwise direction slides.

This novel operation principle is as follows, with this novel matching used bulb, can be former screw button bulb, also can be the remodeling bulb, and promptly lamp holder is a cylinder, and establishes a detent that cooperates with novel described Spring Card 10 get final product on the relevant position.The lamp holder of bulb is inserted in the socket, at this moment, positive contact in bulb positive contact and the socket contacts, push away bulb then, cover 9 moves up in making, and at this moment, the positioning spring card 3 that is in special-shaped chute 17 upper ends 12 is under self torsion and the effect of chute undercut, move along the chute left side, 13 places slide to 18 places, lower end of chute through the turning, and locate this again, simultaneously, since in put and move, the Spring Cards 10 that are inserted in the oblique chute 15 are moved inward under the skewed slot effect, and just in time snap in the detent on the lamp holder, like this, under the effect of wavy spring sheet 11 and Spring Card 10, bulb then has been installed in the socket firmly.When more changing the bulb, on push away bulb, put in making and move, at this moment, positioning spring card slides to 14 places, turning, bottom right of special-shaped chute, at this moment, and under the effect of back-moving spring, interior cover begins to move down, slide into 12 places, special-shaped chute upper end up to positioning spring card and end, at this moment, Spring Card 10 moves outside under oblique chute 15 effects, and shift out detent on the lamp holder, can take off bulb then.

Compared with prior art, the utlity model has novel structure, the convenience that more changes the bulb is installed, and be not subjected to the narrow and small restriction in space, and can prolong the useful life of socket.

Below in conjunction with accompanying drawing this novel embodiment is described further, this novel socket lid 1 that comprises, the socket body, binding post and positive contact, be provided with one in the socket body and slidably overlap 9 in the gear shape, and be equally spaced wavy spring sheet 11 and Spring Card 10, interior cover top is provided with positive source contact 8, cover guide runner 16 linked to each other with binding post 2 in this contact passed, both sides also are provided with two boss 5 above interior cover, between boss and interior cover, be provided with back-moving spring 6, and also be provided with pressing plate 4 between two boss, pressing plate is provided with positioning spring card 3, and the dop of this positioning spring card can slide in the special-shaped chute 17 on being located at slide block 16.

Above-mentioned positioning spring card 3 is a side direction torsion, and the bottom land of chute 17 is made up of several sections different grooves of the depth, so that positioning spring card 3 keeps in chute counterclockwise or clockwise direction slides, with this novel matching used bulb, it can be former screw button bulb, also can be the remodeling bulb, promptly lamp holder be a cylinder, and establishes a detent that cooperates with novel described Spring Card 10 get final product on the relevant position.The lamp holder of bulb is inserted in the socket, at this moment, positive contact in bulb positive contact and the socket contacts, push away bulb then, cover 9 moves up in making, and at this moment, the positioning spring card 3 that is in special-shaped chute 17 upper ends 12 is under self torsion and the effect of chute undercut, move along the chute left side, 13 places slide to 18 places, lower end of chute through the turning, and locate this again, simultaneously, since in put and move, the Spring Cards 10 that are inserted in the oblique chute 15 are moved inward under the skewed slot effect, and just in time snap in the detent on the lamp holder, like this, under the effect of wavy spring sheet 11 and Spring Card 10, bulb then has been installed in the socket firmly.When more changing the bulb, on push away bulb, put in making and move, at this moment, positioning spring card slides to 14 places, turning, bottom right of special-shaped chute, at this moment, and under the effect of back-moving spring, interior cover begins to move down, slide into 12 places, special-shaped chute upper end up to positioning spring card and end, at this moment, Spring Card 10 moves outside under oblique chute 15 effects, and shift out detent on the lamp holder, can take off bulb then.
