Description

A kind of novel decorative lamp water-tight device

The utility model relates to a kind of novel decorative lamp water-tight device.

The water-tight device of existing decorative lamp (mainly being meant horse race lamp), be that the waterproof apron skin is designed to an end is thin slightly, one end is thick slightly, form two concavo-convex levels, a thin slightly end is inserted in the lamp socket collar extension, cling with glue, a thick slightly end is stuck in lamp socket mouth end face, pack into behind the bulb, waterproof apron can play sealing and waterproof action.The shortcoming of this method is, the tautness of waterproof apron is subjected to the viscosity limitation of glue, and glue degree of clinging is poor, and waterproof apron easily comes off, and is difficult to reach good waterproof purpose, and because will use glue, waste material, operation because of difficult, to make efficient low.

The utility model purpose is to overcome the shortcoming of existing decorative lamp water-tight device, and a kind of novel decorative lamp water-tight device is provided, and its sealing tightness is strong, and good water-proof effect, and need not be bonding with glue is saved material, and is easy for installation, make efficiency is high.

For achieving the above object, the technical scheme of the utility model coloured silk is: the utility model is made up of waterproof apron, lamp socket, wherein on the lamp socket collar extension, be provided with groove, waterproof apron one end is thin slightly, one end is thick slightly, and there is a convex tendon at the internal layer middle part, and waterproof apron is enclosed within outside the lamp socket from the lamp socket collar extension, the groove of lamp socket cooperates with the convex tendon of water proof rubber circle, plays waterproof and seals fastening effect.

Aforesaid the utility model, its characteristics are that trapezoidal collar extension is formed at waterproof apron internal layer top.

Owing to take such scheme, the utlity model has good water-proof effect, tightness strong, save material, mounting or dismounting convenient, make high advantage and the effect of efficient, be a kind of desirable decorative lamp water-tight device.

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

Fig. 1 is an integral installation figure of the present utility model.

Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.

Shown in Fig. 1 the utility model integral installation figure, the utility model is made up of lamp socket (10), waterproof apron (20), wherein, waterproof apron (20) internal layer top constitutes trapezoidal collar extension (21), there is convex tendon at the internal layer middle part, lamp socket collar extension (11) is gone up fluted (12), and waterproof apron blocks lamp socket by its swollen tension, and the interior convex tendon of lamp socket collar extension (11) upper groove (12) and waterproof apron engages firmly.

Shown in Fig. 2 the utility model STRUCTURE DECOMPOSITION figure, basis is novel to be made up of lamp socket (10), waterproof apron (20), and wherein waterproof apron internal layer top constitutes trapezoidal collar extension (21), and there is convex tendon at the internal layer middle part; The lamp socket collar extension (11) of lamp socket (10) is gone up fluted (12), and waterproof apron is enclosed within outside the lamp socket from lamp socket collar extension (11).The convex tendon of waterproof apron snaps in the outer port recess (12) of lamp socket, seal fasteningly, and after bulb was packed into, trapezoidal collar extension was close to bulb, thus seal fastening, waterproof, waterproof apron is difficult for downslide.
