Abstract
The utility model provides a cavity seal structure of street lamp, include the seal groove and with this seal groove matched with sealing strip, the sealing strip stretches into the seal groove, just the outer width of sealing strip is less than the inside width of seal groove, be provided with the sealing member of cross -section for the U font in the seal groove. The utility model discloses the creation has better sealed effect, is not carrying on making the sealed grade of cavity promote to IP67 from IP65 under the modified circumstances to other structures of cavity.
Description
Technical field
The invention is related to a kind of cavity sealing structure, belongs to road lighting technical field.
Background technology
The tremendous development of LED street lamp technology so that this street lamp be employed more and more extensive.Due to LED particle and driving
Power supply is more sensitive to steam, and therefore LED street lamp is higher to sealing requirements when using.The knot of conventional LED street lamp sealing at present
Structure as shown in Figure 1, 2, by seal groove, sealing strip and between rounded seal constitute, when actually used, this sealing structure imitate
Fruit is general, and reliability and service life are poor.
Content of the invention
The invention is to solve prior art problem, provides a kind of reliability higher and the more preferable cavity of sealing effectiveness is close
Seal structure.
The technical scheme of the invention is：
A kind of cavity sealing structure of street lamp, the sealing strip match including seal groove and with this seal groove, described sealing
Bar stretches into described seal groove, and the outer wide inner width less than described seal groove of described sealing strip, is provided with and cuts in described seal groove
Face is the seal of U-shaped.
Preferably, the well width of described seal is identical with the outer width of described sealing strip, described seal outer wide with
The inner width of described seal groove is identical.
Preferably, the sidewall thickness of described seal is less than described seal bottom thickness.
Preferably, described seal Sidewall Height is close with the depth of described seal groove.
The rounded seal commonly used at present, is only capable of to sealing it is impossible to integrally seal to seal groove due to small volume
Work in bar top, active area is little, and sealing effectiveness is general.And form the dead band in little space, these dead band meetings in seal groove
Accumulate rainwater when rainy, but when becoming a fine day due to cannot shine the sun, the rainwater of accumulation is difficult to evaporate, and this dead band is due to sky
Between little, stuffy, these rainwater be not easy to from dead band flow out.Because seal is made up of rubber, silica gel or expanded material mostly,
The rainwater of long term accumulation can produce corrosion to seal because of the reason such as rotten of fermenting, and cause seal failure, reliability is poor.
The seal of the invention adopts section U-shaped, and the dead band that former seal is formed is filled up using seal, it is to avoid
The problem of these dead band ponding, increases sealing area, sealing effectiveness of having deducted a percentage simultaneously.Simultaneously using thicker bottom knot
Structure, after sealing strip is pressed into seal groove, sealing strip applies pressure to seal bottom, and the restriction due to seal groove, sealing
Part is squeezed to press to both sides, further the space between filling sealing strip and seal groove the outer surface to sealing strip and seal groove
Inner surface forms pressure, lift-off seal effect.
In sum, the invention has advantages below：
1st, there is preferable sealing effectiveness, the sealing of cavity can be made in the case of cavity other structures not being improved
Grade is promoted to IP67 from IP65；
2nd, avoid the problem that former sealing structure has dead band meeting ponding, extend service life, improve reliability.
Brief description
Fig. 1 is former sealing structure scheme of installation；
Fig. 2 is that former sealing structure seals schematic diagram；
Fig. 3 is this sealing structure scheme of installation；
Fig. 4 seals schematic diagram for this sealing structure.
In figure, 1, seal groove, 2, seal, 3, sealing strip.
Specific embodiment
With embodiment, the invention will be further described below.
Embodiment one：
A kind of cavity sealing structure of street lamp, the sealing strip 3 match including seal groove 1 and with this seal groove 1, described close
Strip of paper used for sealing 3 stretches into described seal groove 1, and the outer wide inner width less than described seal groove 1 of described sealing strip 3, sets in described seal groove 1
It is equipped with the seal 2 that section is U-shaped.The well width of described seal 2 is identical with the outer width of described sealing strip 3, described sealing
The inner width of the outer wide and described seal groove 1 of part 2 is identical.Described seal 2 Sidewall Height is close with the depth of described seal groove 1.
During installation, first seal 2 is filled in seal groove 1, the U-shaped outward opening of seal 2, during sealing, by sealing strip 3
Fill in seal 2 opening, and push up seal 2 bottom, apply certain pressure so that seal 2 bottom of elasticity is squeezed to both sides
Pressure, due to the restriction of seal groove 1, seal 2 bottom extrudes to both sides, after raising seal 2 two side so that completing to install
Seal 2 two side is slightly raised above the two side of seal groove 1.
