Description

Water proof lamp

[technical field]

The utility model is about a kind of light fixture, refers to a kind of water proof lamp especially.

[background technology]

The open air is because of gardening or make the required lighting decoration lamp source of scape, in order to be embedded on the ground or to be installed in the water, generally all can adopt watertight light fitting.Known water proof lamp 1 sees also shown in Figure 1ly, is made of a body 11, loam cake 12, translucent element 13, lamp source 14, first clamping base 15 and second clamping base 16.

Body 11 is a hollow vestlet, is provided with a ring seat 111 in the top of body 11, and the surface of this ring seat 111 is provided with several screws 112, then is provided with an inward flange 113 in the inboard of ring seat 111, is provided with a through hole 114 in addition in the bottom of body 11.

Loam cake 12, it is annular cover for a hollow, this loam cake 12 can be covered on the body 11, and loam cake 12 is provided with a loophole 121, the annular surface of loam cake 12 then is provided with the screw 112 corresponding through holes 122 with body 11 ring seats 111, and this loam cake 12 can combine with body 11 by spiral shell event element S.

Translucent element 13, normally make with the light-transmitting materials of glass, acryl etc., the upper end of this translucent element 13 is a fitting portion 131, this fitting portion 131 is can be embedded in the loophole 121 of loam cake 12, the lower end of translucent element 13 then is a base 132, this base 132 is arranged with a waterproof washer P, and this waterproof washer P breathes out on the inward flange 113 that can place body 11.

Lamp source 14 provides this water proof lamp 1 required illumination and originates, and can be bulb or LED bulb usually.

First clamping base 15, but be the body of wearing for power supply source line L string, these first clamping base, 15 upper ends are provided with threaded portion 151, and then being extended with a Fastening device 152, the first clamping bases 15 in the lower end of first clamping base 15 is to link by nut 153,154 and body 11.

Second clamping base 16, but be the pedestal of wearing for power supply source line L string, and this second clamping base 16 can be sheathed and be screwed together in the threaded portion 151 of first clamping base 15.

Known water proof lamp 1 is when assembling, at first, be that first clamping base 15 is arranged in the through hole 114 of body 11 bottoms and with nut 153,154 respectively in body 11 bottoms, first clamping base 15 is fixed in the bottom of body outward, again power line L is penetrated to the inside of body 11 by the Fastening device 152 of first clamping base 15, and pass to do by the ring seat 111 of body 11 and connect with lamp source 14, when lamp source 14 with power line L connect finish after, again lamp source 14 is inserted in the body 11, utilize second clamping base 16 to be screwed together in the threaded portion 151 of first clamping base 15 afterwards, can make power line L be tightened fixing by the Fastening device 152 of first clamping base 15, at this moment behind the base 132 sheathed waterproof washer P with translucent element 13, be placed on the inward flange 113 of body 11, again loam cake 12 is covered on the ring seat 111 of body 11, with bolting element S loam cake 12 is locked in the ring seat 111 of body 11 at last, water proof lamp 1 after the assembling, as shown in Figure 2.

On take off known water proof lamp 1 when using, have following disappearance:

One, unbalanced stress, the waterproof effect of sealing is not good: because translucent element 13 is to be locked between loam cake 12 and the body 11 by bolting element S, respectively this bolting element S must screw respectively when installing, so each bolting element S and each screw 112, the stress that through hole is 122 can be not identical, that is, the adhesion that each bolting element S is provided can't make this loam cake 12 be packed in the body 11 of body 11 fully, caused the fastening force inequality of 12 of this ring seat 111 and loam cakes, and then the sealing state that makes waterproof washer P formed by packing is relatively poor, and the waterproof effect that is provided is not good.

Two, assembling trouble: water proof lamp 1 is when assembling, must earlier power line L be penetrated to the inside of body 11 by the Fastening device 152 of first clamping base 15 of body 11 belows, again by the ring seat 111 of body 11 pass with lamp source 14 do connect after, establishing assembling with bolting element S spiral shell again is locked in loam cake 12 on the ring seat 111 of body 11, not only consuming time, also increased the cost of making.

Three, inconvenient maintenance: because water proof lamp 1 generally all is installed in the open air, the thread of this bolting element S causes oxidation and rusting because of the capillarity of water easily, and the time one is of a specified duration, and bolting element S just can't dismantle, thereby increases the degree of difficulty that keeps in repair and change lamp source 14.

Four, the clamping base device hardens easily: because power line L only is it is tightened on the Fastening device 152 that is fixed in first clamping base 15 by second clamping base 16, therefore the Fastening device 152 that gets off for a long time can harden because of going bad of plastic cement, cause being subjected to the capillarity of water easily and seep water, cause the damage of water proof lamp 1.

Five, translucent element 13 crackies: owing to translucent element 13 is normally made with glass, and the pass that nothing links mutually between translucent element 13 and the loam cake 12 is that when disassembling water proof lamp 1, translucent element 13 is easily because of the breakage of dropping accidentally.

Six, bolting element S subjects to destroy: because bolting element S is the surface that exposes to loam cake 12, this bolting element S is very easy to make the destruction that is subjected to unworthy one's share of expenses for a joint undertaking after sealed assembling.

[utility model content]

Because known water proof lamp 1 has above-mentioned disappearance, the purpose of this utility model provides a kind of water proof lamp, by being provided with waterproof washer between the internal thread of loam cake and translucent element and being screwed, the external screw thread of loam cake then is provided with waterproof washer with the bearing of body top and is screwed, and makes the waterproof washer can average force, forms sealing state, can avoid water proof lamp to infiltrate in the body because of the capillarity of water, cause the damage in lamp source,, and have advantage easy to assembly with the raising waterproof effect.
