Fig. 4 shows the partial enlargement of the assembling original state of the assembling structure for gasket ring of the utility model one embodiment
Diagrammatic cross-section；Show the section signal of the partial enlargement for being completed state of Fig. 4 side compression sealing structure
Figure.With reference to figure 4, in the present embodiment, assembling structure for gasket ring includes lens barrel 1, eyeglass 2 and sealing ring 3.Lens barrel 1 has and eyeglass
Assemble assembling section corresponding to stroke, what the assembling section was included with the first internal diameter first is segmented 12 and the with the second internal diameter
Two-section 13.The region (referring to the region coordinated with sealing ring after being completed) that lens barrel coordinates with sealing ring is located at described second
Segmentation 13, and first internal diameter is more than second internal diameter.
In the present embodiment, eyeglass 2 has the side being adapted to the assembling section of the lens barrel 1, and the side has diameter
The lens barrel matching section 22 being coincide with first internal diameter, and the sealing ring matching section 23 positioned at the region coordinated with sealing ring.
In stroke is assembled, it is described first segmentation 12 and the sealing ring matching section 23 between gap be more than described second segmentation 13 with
Gap between the sealing ring matching section 23 so that the lateral pressure of first segmentation, 12 pairs of sealing rings 3 is less than described the
Lateral pressure of the two-section 13 to sealing ring 3.So, in entirely assembling stroke, the sealing ring decrement of partial journey is dropped
It is low so that frictional force reduces, final to lift camera lens sealing property so as to reduce the distortion of sealing ring.
Further, referring still to Fig. 4 and Fig. 5, in one embodiment, the eyeglass 2 has optical axis, the sealing ring
Matching section 23 has first contact surface parallel with the optical axis, has second to connect in second segmentation 13 of the lens barrel 1
Contacting surface, sealing ring can be accommodated between second contact surface and first contact surface and on the direction of the optical axis
The sealing ring is formed and extruded.The lens barrel matching section 22 of eyeglass 2 forms first step with the junction of sealing ring matching section 23
21, the region coordinated with sealing ring of lens barrel 1 forms second step 11 corresponding with the first step.1 group of eyeglass 2 and lens barrel
After dress, the first step 21 can form the toroidal cavity 4 for accommodating sealing ring with the second step 11.Perpendicular to the light
On the direction of axle, the thickness under the relaxed state of the sealing ring 3 is more than the inside radius of the described second segmentation 13 and the eyeglass 2
The difference of outer radius at first contact surface so that sealing ring 3 has enough decrements under installation state, real
Existing sealing effectiveness.
Further, referring still to Fig. 4 and Fig. 5, in one embodiment, the assembling section of lens barrel 1 also includes transient sublevel
14, the transient sublevel 14 is connected between first segmentation 12 and second segmentation 13.The internal diameter of the transient sublevel 14
Second internal diameter is progressively transitioned into from first internal diameter.The transient sublevel 14 is formed using chamfering.Transient sublevel it is interior
The preferred scope that side forms angle with optical axis is 10 ° -40 °.So, in stroke is assembled, the change of sealing ring decrement is slow
Transition, eliminate because sealing ring caused by sealing ring decrement drastic change is damaged, distorts, and then lifts camera lens sealing property.
Further, referring still to Fig. 4 and Fig. 5, in one embodiment, the assembling structure for gasket ring also includes the
Two eyeglasses 5, the lens barrel 1 also include main paragraph 15, and second eyeglass 5 is installed in its inner side.The internal diameter of the main paragraph 15 of lens barrel 2
Less than the second internal diameter of the segmentation of lens barrel second 13.So, can be by second eyeglass 5 after lens barrel 1, eyeglass 2 and sealing ring assembling
It is sealed in inside camera lens.For ease of being distinguished with the second eyeglass 5, eyeglass 2 is also referred to as the first eyeglass sometimes herein.
In above-described embodiment, assembling structure for gasket ring is used to the sealing assembling of optical lens, but it is to be appreciated that this practicality
It is new to be not limited in field of optical lens.For example, in one embodiment, assembling structure for gasket ring includes sealing ring, sheet
Component and cylindrical member.Flat member has axis, and the flat member can be along the axis relative to the cylindrical member
It is mobile and assembled therewith.Also, the flat member and the cylindrical member are respectively provided with the region coordinated with sealing ring
And form the cavity that can accommodate the sealing ring.Wherein, the cylindrical member has assembles corresponding group of stroke with flat member
Section is filled, the assembling section includes the first segmentation with the first internal diameter and the second segmentation with the second internal diameter.The tubular structure
Part is more than second internal diameter with the region that the sealing ring coordinates positioned at the described second segmentation, first internal diameter.So, exist
In whole assembling stroke, the sealing ring decrement of partial journey is lowered so that frictional force reduces, so as to reduce sealing ring
Distortion, the final sealing property for lifting package assembly.
Further, in one embodiment, the assembling section of cylindrical member also includes transient sublevel, and it is connected to institute
State between the first segmentation and second segmentation, the internal diameter of the transient sublevel is progressively transitioned into described the from first internal diameter
Two internal diameters.So, in stroke is assembled, sealing ring decrement changes slow transition, eliminates because sealing ring decrement drastic change is drawn
Sealing ring breakage, the distortion risen, and then lift the sealing property of package assembly.
