Description

A kind of waterproof mounting assembly of lens

Technical field

This utility model is related to LED lamp field, the waterproof mounting assembly of particularly a kind of lens.

Background technology

LED, as a kind of point source, needs to coordinate necessary optical module such as Lamp cup, lens etc. to be joined during its use Light, and lens are due to good in optical property, small volume, so application is relatively broad, out of doors in light fixture, lens are installed also to be needed to consider To water resistance, presently mainly waterproof sealing is realized by water proof ring fitted seal circle, using this structure, if desired preferably Sealing property is it is necessary to configure wider sealing ring, but such sealing ring can cover more rims of the lens, influences whether Effective optical region of mirror, only can be suitably used for small light source；If desired ensure effective optical region of lens, be suitable for big light source, just Need to reduce sealing ring, have influence on sealing property.

Content of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of waterproof mounting assembly of lens.

This utility model solves its technical problem and be employed technical scheme comprise that：

A kind of waterproof mounting assembly of lens, including pressure ring and sealing ring, described sealing ring cross-section is of an L-shaped structure, its bag Include inner ring corresponding with lens and annular is arranged on the shirt rim outside inner ring；Described pressure ring include compressing inner ring internal ring and The outer shroud of shirt rim can be compressed.

Mutually corresponding installing hole is offered on described pressure ring and sealing ring, described pressure ring and sealing ring can pass through screw Install through installing hole and compress lens.

Groove corresponding with rims of the lens is offered on described inner ring inwall.

Described sealing ring bottom surface annular is provided with some stripeds.

The beneficial effects of the utility model are：A kind of waterproof mounting assembly of lens, including pressure ring and sealing ring, described close Seal section is of an L-shaped structure, and it includes inner ring corresponding with lens and annular is arranged on the shirt rim outside inner ring；Described pressure ring bag The outer shroud including the internal ring that can compress inner ring and can compressing shirt rim, this utility model passes through using the L-shaped sealing ring in section And configure the pressure ring being adapted to it, can effectively improve the sealing area of sealing ring it is ensured that sealing water resistance, and by interior Circle and the design of shirt rim, can reduce the width of inner ring, reduce sealing ring and rims of the lens area that pressure ring covers is so that lens There is larger effective optical region, can be applied to big light source.

Brief description

With reference to the accompanying drawings and examples this utility model is further illustrated.

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

Fig. 2 is schematic cross-section of the present utility model；

Fig. 3 is decomposing schematic representation of the present utility model.

Specific embodiment

Referring to figs. 1 to Fig. 3, Fig. 1 to Fig. 3 is the structural representation of one specific embodiment of this utility model, as illustrated, A kind of waterproof mounting assembly of one lens, including pressure ring 1 and sealing ring 2, described sealing ring 2 section is of an L-shaped structure, it include with The corresponding inner ring 21 of lens 9 and annular are arranged on the shirt rim 22 outside inner ring 21；Described pressure ring 1 includes compressing inner ring 21 Internal ring 11 and the outer shroud 12 that can compress shirt rim 22, seal lens 9 top edge by inner ring 21, seal lens 9 by shirt rim 22 Bottom, you can complete the waterproof sealing to lens 9, this utility model pass through using the L-shaped sealing ring in section and configure with The pressure ring of its adaptation, can effectively improve the sealing area of sealing ring 2 it is ensured that sealing water resistance, and by inner ring 21 with The design of shirt rim 22, can reduce the width of inner ring 22, reduce sealing ring 2 and lens 9 edge area that pressure ring 1 covers so that Lens 9 have larger effective optical region, can be applied to big light source.

Preferably, described pressure ring 1 and sealing ring 2 offer mutually corresponding installing hole 3, described pressure ring 1 and sealing ring 2 Can install through installing hole 3 and compress lens 9 by screw, certainly, in specific implementation process, also can pass through buckle, rotation Turn the installation that the structures such as screens realize pressure ring 1, be not described in detail here.

Preferably, described inner ring 21 inwall offers groove 211 corresponding with lens 9 edge, during use, lens 9 Edge embeds groove 211, and further raising seals water resistance.

Preferably, described sealing ring 2 bottom surface annular is provided with some stripeds 23, when sealing ring 2 is compacted, striped 23 quilt Crimp, sealed waterproof effect is good.

Above preferable enforcement of the present utility model is illustrated, certainly, this utility model can also using with The different form of above-mentioned embodiment, those of ordinary skill in the art without prejudice to the present invention spirit on the premise of made etc. Same conversion or corresponding change, all should belong in protection domain of the present utility model.
