Abstract
The invention discloses a large-aperture focusing lens unstressed clamping mechanism, which comprises a lens frame, a pressing ring, three or more hollow nylon screws and a certain amount of fixing colloid. The large-aperture focusing lens unstressed clamping mechanism utilizes the hollow nylon screws for adjusting a circumferential axial center of a focusing lens to coincide with a circumferential axial center of the lens frame of the focusing lens and then fixing the focusing lens and the lens frame, the colloid is injected into a circumferential gap between the focusing lens and the lens frame via hollow circular holes of the hollow nylon screws, and the focusing lens and the lens frame are integrated after solidification of the colloid. The large-aperture focusing lens unstressed clamping mechanism can effectively reduce the stress of clamping on the lens, and has the advantages of being concise in structure, stable and reliable, and convenient and fast in installation and disassembly.
Description
Technical field
The present invention relates to lens, particularly a kind of heavy caliber condenser lenses are unstressed clamping mechanism, it is mainly used in heavy caliber
The clamping of condenser lenses, the mechanical clamping stress very little that this clamping mechanism introduces, clamping mechanism is reliable and stable to be easy to adjust, and easily
In dismounting.
Background technology
The clamping mechanism of various general heavy caliber condenser lenses, the screw one on the mirror holder circumference of heavy caliber condenser lenses
As all adopt metal screws, of a relatively high stress can be produced, be relatively easy to damage lens side, another way is from side
Side irrigates colloid, and stress is little but is typically very difficult to dismantle.
Content of the invention
It is an object of the invention to provide a kind of stressless clamping mechanism of heavy caliber condenser lenses, gathered with reducing heavy caliber
The mechanical stress that focus lens produce in clamping process, this clamping mechanism can effectively reduce the stress that clamping produces to eyeglass, tool
There is simple for structure, reliable and stable, installation and removal conveniently feature.
The technical solution of the present invention is as follows：
A kind of unstressed clamping mechanism of condenser lenses is it is characterised in that include picture frame, trim ring, fixing glue and hollow nylon
Screw；
Described picture frame be have for condenser lenses place interior step cylindrical structural member, this cylindrical structural member cylindrical
It is uniformly distributed the radial direction tapped through hole of more than 3 week, this tapped through hole is screwed into for described hollow nylon screw, this cylindric structure
Top half inside part has female thread；
Described hollow nylon screw has B through hole diametrically along axis, for described fixing glue perfusion；
The external screw thread of described trim ring is matched with the female thread of picture frame.
The adjustment process of the present invention is as follows：
Select the unstressed clamping mechanism of the condenser lenses being adapted with condenser lenses size to be fixed, picture frame is placed on
On independent work platformses, then condenser lenses are placed on the inner flange of picture frame, after alignment lens and picture frame center, trim ring are revolved
Enter in picture frame, adjust the symmetrical hollow nylon screw of picture frame surrounding so that the central coaxial of picture frame and condenser lenses, then lead to
Silica gel is poured at condenser lenses and the circumferential gap of picture frame the diameter B through hole crossing hollow nylon screw along axis, passes through
Condenser lenses are fixed in picture frame for silica gel solidification.During dismounting, unscrew hollow nylon screw, screw out described trim ring and can be taken off
Condenser lenses.
The technique effect of the present invention：
The unstressed clamping mechanism of condenser lenses of the present invention can effectively reduce the stress that clamping produces, sleeve mechanism to eyeglass
Simple for structure, reliable and stable, install and dismounting is all convenient and swift.
Brief description
Fig. 1 is the assembling section of the unstressed clamping mechanism of condenser lenses of the present invention
Fig. 2 is the outside drawing of picture frame of the present invention
Fig. 3 is the outside drawing of trim ring of the present invention
Fig. 4 is the profile of hollow nylon screw of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples, but should not limit the protection model of the present invention successively
Enclose.
Refer to Fig. 1, Fig. 4, as seen from the figure, condenser lenses of the present invention are unstressed clamping mechanism, including picture frame 1, trim ring 2,
Fixing glue 3 and hollow nylon screw 4.Described picture frame 1 is the main fixed frame of condenser lenses, circular with interior step circular hole
Component, the cylindrical circumferential direction along annulus is uniformly distributed in the tapped through hole of more than three, this tapped through hole in order to be screwed into hollow Buddhist nun
Imperial screw 3, in it, step circular hole is the stop dog component that condenser lenses prevent lens landing in clamping, and this carries the cylinder of inner flange
It is female thread inside shape component top half, the external screw thread cooperation with trim ring 2, inner flange only serves prevents eyeglass landing from acting on,
Not with lens contacts.The described external screw thread of trim ring 2 is cooperated with female thread on picture frame 1, heavy caliber condenser lenses dress
It is screwed into trim ring 2 after entering picture frame 1, but does not contact with condenser lenses, that is, complete preliminary clamping.Described hollow nylon screw 4 is
The screw that external screw thread is, material is nylon material (or other nonmetallic materials have the material of necessarily elasticity), and inside is along axis side
To the through hole having an a diameter of B, multiple hollow nylon screws 4 are all screwed into the screwed hole on the circumference of picture frame 1, adjust hollow Buddhist nun
Imperial screw 4 ensures that condenser lenses are concentric with picture frame 1, then is fixed along the diameter B through hole perfusion of axis by hollow nylon screw 4
Glue 3, at the circumferential gap of condenser lenses and picture frame 1, condenser lenses is fixed in picture frame 1, plays unstressed fixing heavy caliber and gathers
The effect of focus lens.
Trial show that, the hollow nylon screw of the present invention, effectively reduce the lateral clamping stress of heavy caliber condenser lenses,
Screw central through hole makes injecting glue convenient, uniformly, increased reliability and the overall structure stability of clamping mechanism, overall
Balance of mechanism and axiality are easy to adjust, Stability Analysis of Structures, are convenient to mount and dismount quick.
It should be noted last that, above example only in order to technical scheme to be described and unrestricted, although ginseng
According to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that, can be to invention
Technical scheme is modified or equivalent, and without deviating from the spirit and scope of technical solution of the present invention, it all should be covered
In the middle of scope of the presently claimed invention.
