Abstract

The utility model relates to a lampshade locking device comprising a lamp body and a lampshade mounted at the top part of the lamp body. The connection part for the lamp body and the lampshade is a round shape; a lug boss is arranged on the internal surface at the top part of the lamp body; a clamping groove is correspondingly formed on the outer surface of the lampshade; the lug boss is rotated and mounted in the clamp groove, so that the installed lampshade is restricted by the lug boss and can not be pulled out upwards; a base is mounted at the top part of the lamp body and extends into the lampshade; an elastic clamping sheet is arranged on the side wall of the base, with a clamping platform facing outwards at the end part; a bayonet and a through hole are formed on the lampshade and the lamp body corresponding to the clamping platform. After the lug boss is matched and mounted with the clamp groove, the clamping platform under the elastic force action of the elastic clamping sheet extends into the through hole to be locked through the bayonet again, so that the mounted lampshade is hard to fall; and the design has the advantages of reasonable structure and convenient installation.

Description

A kind of lampshade locking device

Technical field

The utility model relates to a kind of lampshade locking device.

Background technology

Small-sized light fixture commonly used generally all is provided with lampshade, lamp body has screw to fix with assembling mode between the lampshade, spiral is connected or car coat type, the former need dismantle screw when more changing the bulb, be inconvenient to operate the shortcoming that gets loose easily that the light fixture of spiral connection and car coat type all exists.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, easy for installation, lampshade locking device of being difficult for getting loose.

The technical scheme that the utility model adopted is:

A kind of lampshade locking device, the lampshade that comprises lamp body and be installed on the lamp body top, lamp body and lampshade connecting portion are round-shaped, described lamp body top inner surface is provided with boss, the corresponding draw-in groove that is provided with of the outer surface of lampshade, the boss rotation is installed in the draw-in groove, make the lampshade after installing up to be transferred to by the constraint of boss, described lamp body top is equipped with base, base stretches in the lampshade, the sidewall of described base is provided with elastic card, and the end of elastic card has the Ka Tai that protrudes outwardly, and described lampshade and lamp body are being provided with bayonet socket and through hole respectively corresponding to the Ka Tai place.

Further improvement of the utility model, described base are the plastic cement seat, and described elastic card is and the integrated plastic parts of base.

The beneficial effects of the utility model are: when boss cooperate with draw-in groove install after, under the elastic force effect of elastic card, Ka Tai stretches in the through hole through bayonet socket again and locks, and makes the lampshade after installing be not easy to come off, the design is rational in infrastructure, easy for installation, only need past interior pressure when more changing the bulb with Ka Tai as needs, lampshade is outwarded winding gets final product again, further, described elastic card is to make with base is one-body molded, has simplified production technology, makes the more compact structure of light fixture.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model;

Fig. 3 is the exploded view of another angle.

The specific embodiment

Referring to figs. 1 through Fig. 3, a kind of lampshade locking device, the lampshade 2 that comprises lamp body 1 and be installed on lamp body 1 top, lamp body 1 is round-shaped with lampshade 2 connecting portions, described lamp body 1 top inner surface is provided with boss 11, the corresponding draw-in groove 21 that is provided with of the outer surface of lampshade 2, boss 11 rotations are installed in the draw-in groove 21, make the lampshade after installing up to be transferred to by the constraint of boss, described lamp body 1 top is equipped with base 3, base 3 stretches in the lampshade 2, lampshade 2 is packed into the gap between base and lamp body shell, the sidewall of described base 3 is provided with elastic card 31, and the end of elastic card 31 has the card platform 32 that protrudes outwardly, and lampshade 2 and lamp body 1 are being provided with bayonet socket 22 and through hole 12 respectively corresponding to card platform 32 places.

Further, described base 3 is made for plastic cement or plastics, as ABS feed back etc., not only material cost is lower, and injection mo(u)lding easily, and production technology is simple, described elastic card 31 is and base 3 integrated plastic parts, make the more compact structure of light fixture, in addition, the mode of metallic elastic card or spring top flat can be installed on base also.

Further, described elastic card 31 is provided with hypotenuse 33 at the top of card platform 32, and when lampshade 2 is installed, the lower limb of lampshade 2 can will block platform 32 toward interior pressure by hypotenuse 33, thereby make lampshade 2 import easily.

Further, the front end of described draw-in groove 21 is provided with the guide groove 23 that can make lampshade vertically import from boss 11, in when assembling, the guide groove 23 of lampshade can hold boss 11 just, so lampshade can vertically be packed in the lamp body 1, then draw-in groove 21 and boss 11 are clamped the lampshade rotation again, thereby the constraint lampshade can vertically not move, and makes structure more reasonable, above-mentioned just preferred version, in addition, the mode that also opening of draw-in groove can be designed to be tilted to imports boss.

Described draw-in groove 21 makes the boss 11 that snaps in the draw-in groove 21 more firm at the limited block 24 that is provided with projection corresponding to boss 11 rearward end outsides, has increased the stability of locking device.

Further, the end face of described base 3 is reflective surfaces, when light fixture is worked from light source shine the bottom light be reflected away, improved the luminous efficiency of light fixture.

The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
