Description

A kind of sealing-ring

Technical field

The utility model relates to a kind of sealing-ring.

Background technology

At present, in order to LED lens module integral sealing is arranged on other parts, common way installs sealing-ring between LED lens module and other parts, and the mutual extruding sealing-ring of LED lens module and other parts enables LED lens module and other parts be tightly connected.

In the prior art, for LED lens are installed installation panel mostly refined gram force make, material is more crisp. And existing sealing-ring is the sealing-ring that upper and lower surface is plane mostly. When being tightened on other parts by installation panel by bolt, the effect extruding distortion that sealing-ring is tightened by bolt, the preglabellar field of sealing-ring and outer edge all protruding and past outer edge can extend because of stress deformation. If the screwing force of bolt is inadequate, then sealing-ring can cause the sealing weak effect of sealing-ring because of the projection of outer edge; If the screwing force of bolt is enough, the outer edge that the distortion of the outer edge of sealing-ring can extend to installation panel makes the stress deformation of installation panel own that installation panel even can be made to ftracture, and damages installation panel by pressure, and sealing-ring self also may damage.

Practical novel content

The technical problems to be solved in the utility model is to provide the LED lens mould that a kind of structure is simple, can prevent erecting of panel from ftractureing.

In order to solve the problems of the technologies described above, a kind of technical scheme that the utility model adopts is: a kind of sealing-ring, for the installation of LED lens module. Described sealing-ring is attached to the surface installing of LED lens module, described sealing-ring is in annular, the upper surface inner circumferential of described sealing-ring is provided with the first step, the upper surface external circumferential of described sealing-ring is provided with the 2nd step, the step surface of described first step and the 2nd step is all lower than sealing-ring upper surface, described first step arranges formation circular step around the inner circumferential of sealing-ring, and described 2nd step arranges formation circular step around the external circumferential of sealing-ring.

Preferably, the upper surface of described sealing-ring has also offered groove.

Further, described groove has multiple, and described multiple groove is along upper surface circumferential uniform of sealing-ring.

Preferably, described sealing-ring is silica gel circle.

Upper surface involved above defines with the surface work of sealing-ring away from LED lens module.

Scope of the present utility model, the technical scheme being not limited to the particular combination of above-mentioned technology feature and become, also should contain other technical scheme being carried out arbitrary combination by above-mentioned technology feature or its equivalent feature and being formed simultaneously. Such as, disclosed in above-mentioned feature and the application, (but being not limited to) has the technical scheme etc. that the technology feature of similar functions is replaced mutually and formed.

Owing to technique scheme is used, the utility model compared with prior art has following advantage: the first step and the 2nd step offering indent on sealing-ring, sealing-ring is made to have the accommodation space of deformation after stress deformation, sealing-ring centre stress deformation inwardly extends outward and is filled in the first step, in the interior concave space that 2nd step is formed, sealing-ring can not extrude the outer edge that distortion extends into LED lens module, both the sealing effect of sealing-ring can have been ensured, LED lens module can be made again because of the stress deformation of sealing-ring not extrude cracking, the extrusion damage of sealing-ring self can also be prevented in addition.

Embodiment

As shown in Figures 1 to 7, a kind of sealing-ring described in the utility model, for the installation of LED lens module 20. Described sealing-ring 10 is silica gel circle. Described sealing-ring 10 is attached to the surface installing of LED lens module 20, described sealing-ring 10 is in annular, the upper surface inner circumferential of described sealing-ring 10 is provided with the first step 1, the upper surface external circumferential of described sealing-ring 10 is provided with the 2nd step 2, the step surface of described first step 1 and the 2nd step 2 is all lower than sealing-ring 10 upper surface, described first step 1 arranges formation circular step around the inner circumferential of sealing-ring 10, and described 2nd step 2 arranges formation circular step around the external circumferential of sealing-ring 10.

The upper surface of described sealing-ring 10 has also offered groove 3. Described groove 3 has multiple, and described multiple groove 3 is along upper surface circumferential uniform of sealing-ring 10.

Offering the sealing-ring groove 21 of accommodating sealing-ring 10 with sealing-ring 10 on the surface that LED lens module 20 contacts, sealing-ring 10 is being arranged in sealing-ring groove 21 when not being squeezed effect, and its upper surface is the surface higher than LED lens module 20. When LED lens module 20 is tightened on other parts by bolt, sealing-ring 10 is squeezed and extends in sealing-ring groove 21 internal strain, and periphery outwards extends into the outer edge of sealing-ring groove 21, inwardly extends into the preglabellar field of sealing-ring groove 21. Due to the setting of the first step 1 and the 2nd step 2, the extension of sealing-ring 10 is made to have had accommodation space, it is possible to the edge effectively preventing sealing-ring 10 from extruding LED lens module 20 causes the extruding distortion of LED lens module 20 and the damage of sealing-ring 10 self. The arranging of sealing-ring 10 upper surface upper groove 3 provides distortion to sealing-ring 10 further and steps down space, and sealing-ring 10 is squeezed middle part can not be protruding, can extend and be filled to groove 3 place, ensure that the stopping property of sealing-ring.

As mentioned above, it is necessary, we are illustrated according to objective of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method. The practitioner of correlative technology field can carry out different changes and enforcement in the scope that technological thought of the present utility model is permitted.
