Limitation.
The content of the invention
The purpose of this utility model is to provide the LED with waterproof construction that a kind of structure setting is reasonable and water resistance is good
Street lamp.
The technical solution for realizing the utility model aim is a kind of LED street lamp with waterproof construction, including lamp holder, is set
Lampshade on the lamp holder is provided with light-emitting LED circuit board in the lamp holder, and connecting portion is provided on the lamp holder,
Power cord perforation is provided on the connecting portion, annulus sealed groove is provided on the inner wall of power cord perforation,
At least two adjusting screw holes being connected with the annulus sealed groove are provided on the outer wall of the connecting portion, the annulus is close
The roof of groove is sealed as the low inclined surface in inner end, torus is provided in the annulus sealed groove, in the torus
Lateral surface be enclosed with rubber seal, adjusting screw rod is provided in the adjusting screw hole, in the inner end of the torus
Resetting spring is fixed between the inner wall of the annulus sealed groove, the resetting spring is pressed on circle respectively with adjusting screw rod
On two sides of ring body, when the adjusting screw rod moves, torus is promoted inwardly makes torus be moved up in inclined surface
It is dynamic, so that rubber seal compresses completes waterproof sealing on the power line.
The connecting portion includes fixed part integrally formed with the lamp holder and fixed by screw rod with the fixed part
Covering part, the junction of the power cord perforation in fixed part and covering part.
The junction of the fixed part and covering part is provided with Waterproof glue line.
The utility model has positive effect：The structure setting of the utility model is reasonable, be provided with torus and
Torus is coated with rubber seal, after power cord installation, can move torus by adjusting screw rod, pass through
The guiding of inclined surface, so as to so that rubber seal is securely pressed on power cord surface, ensure that water resistance, and can be with
It needs to control to adjust the position of screw rod, ensures the sealing reliability of rubber seal, strong applicability and practicability is good.
Description of the drawings
In order to which the content for making the utility model is more likely to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, wherein：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is the structural representation of the utility model
Figure.
See Fig. 1, a kind of LED street lamp with waterproof construction, including lamp holder 1, the lampshade 2 being arranged on the lamp holder 1,
Light-emitting LED circuit board 3 is provided in the lamp holder 1, connecting portion 4 is provided on the lamp holder 1, is set on the connecting portion 4
Power cord perforation 5 is equipped with, annulus sealed groove 6 is provided on the inner wall of power cord perforation 5, in the outer of the connecting portion
At least two adjusting screw holes 7 being connected with the annulus sealed groove 6, the top of the annulus sealed groove 6 are provided on wall
Wall is the low inclined surface 8 in inner end, torus 9 is provided in the annulus sealed groove 6, in the lateral surface of the torus
Be enclosed with rubber seal 10, adjusting screw rod 11 be provided in the adjusting screw hole 7, the inner end of the torus 9 with
Resetting spring 12 is fixed between the inner wall of the annulus sealed groove 6, the resetting spring 12 supports respectively with adjusting screw rod 11
It is pressed on two sides of torus 9, when the adjusting screw rod moves, torus is promoted inwardly is tilting torus
It is moved on face, so that rubber seal compresses completes waterproof sealing on the power line.
The connecting portion 4 includes fixed part 41 integrally formed with the lamp holder and is consolidated with the fixed part by screw rod 42
Fixed covering part 43, the junction of the power cord perforation in fixed part and covering part.
The junction of the fixed part and covering part is provided with Waterproof glue line 44.Processing and group are facilitated using this structure
Dress, and the structures such as ease of assembly torus.
The structure setting of the utility model is reasonable, is provided with torus and is coated with rubber seal in torus
Circle after power cord installation, can move torus, by the guiding of inclined surface, so as to so that rubber by adjusting screw rod
Glue sealing ring is securely pressed on power cord surface, ensure that water resistance, and can need to control to adjust the position of screw rod, protects
Demonstrate,prove the sealing reliability of rubber seal, strong applicability and practicability is good.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
