Description
Technical field
The present invention relates to optical fields, more particularly, to a kind of lens module and use the projection device of the lens module.
Background technique
Optical element, it is very high to dust susceptibility such as the laser light source of projection device, the luminous lens of laser light source it is dust-proof
Effect directly influences the service life of laser light source.The luminous lens of major part laser light source transport or turn without dustproof construction at present
Dust easily enters in laser light source during fortune, to accelerate the brightness decay of laser light source, reduces making for laser light source
Use the service life.Existing luminous lens are carried out with dust-proof method to be mainly: the periphery of luminous lens prescribes glue groove, in glue groove
Dispensing reaches dust-proof effect, i.e. dispensing mode；Alternatively, the external of luminous lens increases structural member and seal glass, reach dust-proof
Effect, i.e. seal closure mode.However, dispensing mode complex process (needing to toast), not easy to disassemble, difficulty is reprocessed.Seal closure side
Sealing structure space is larger required for formula and Material Cost is higher, for there is the laser light source of space requirement cannot achieve.
Therefore, it is really necessary to provide the new lens module of one kind to solve the above problems.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of novel lens mould groups, to solve in the prior art because dust-proof
Effect difference and the problem of influence properties of product.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of lens module, including tool are provided
There is the shell of mounting hole, accommodate lens in the mounting hole, installation screw thread, the camera lens mould are machined in the mounting hole
Group further includes the threaded pressure ring to match with the installation screw thread, and the threaded pressure ring is mounted on the installation by knob mode
In hole, to fix and seal the lens.
Preferably, the lens module further includes described for buffering between the lens and the threaded pressure ring
The lens tabletting of mirror pressure.
Preferably, the lens module further includes the sealing ring that the lens periphery is arranged in.
Preferably, the internal diameter of the sealing ring is equal to the outer diameter of the lens.
Preferably, the sealing ring is prepared using elastic material.
Preferably, the lens tabletting is cyclic structure, and is connected to the bottom of the lens.
Preferably, the inner ring of the sealing ring fits with the lens, the outer ring of the sealing ring and the shell phase
Fitting, the upper surface of the sealing ring fits with the lens tabletting.
Preferably, the claw that the lens are played with pressure pair and fixed function is provided in the lens tabletting.
Preferably, the number of the claw is at least two, and each claw is arranged equally spaced in the lens tabletting.
In order to solve the above technical problems, another technical solution used in the present invention is: providing a projection device, packet
Include lens module as described above.
The beneficial effects of the present invention are: being in contrast to the prior art, the present invention provides a kind of lens module, camera lens mould
Installation screw thread is machined in the mounting hole of group, threaded pressure ring is installed in the mounting hole by knob mode, with fixed and close
Seal the lens.The present invention can be such that lens reach in the case where stablizing fixed effect is fully sealed, to guarantee camera lens mould
The whole leakproofness of group.The invention structure is simple, low in cost.
Detailed description of the invention
Fig. 1 is the decomposition texture schematic diagram of lens module of the present invention；
Fig. 2 is the assembly structure diagram of lens module of the present invention.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of lens module using the projection device of the lens module to solve in the prior art because dust-proof
Effect difference and the problem of influence properties of product.As depicted in figs. 1 and 2, lens module of the present invention includes shell 1, is housed in shell 1
Interior lens 2 and the mounting assembly for fixing lens 2.
It is provided on shell 1 for accommodating mounting hole at lens 2.In the present embodiment, mounting assembly includes lens pressure
Piece 4, sealing ring 3 and threaded pressure ring 5.
Wherein sealing ring 3 is sealing O circle, is prepared using elastic material.In the present embodiment, the internal diameter of sealing ring
Equal to the outer diameter of lens.In use, sealing ring is set in the periphery of lens.The side of sealing ring 3 is bonded with lens 2
Setting, the other side is bonded setting with the inner surface of the mounting hole of shell 1, so that shell 1 forms seal shape after mounted lens 2
State.In selectable other embodiments, sealing ring 3 can also be in contraction state, and internal diameter is less than the outer diameter of lens, as long as
It is stretched in working condition, is set in the periphery of lens 2, be that can be implemented.
It is machined with installation screw thread inside mounting hole, threaded pressure ring 5 and installation screw thread match setting, and threaded pressure ring 5 passes through
Knob mode, which is mounted in mounting hole, fixes and seals lens 2.In an assembling process, first lens 2 are arranged in mounting hole
In lens fixing groove, and it is sequentially placed into sealing ring 3 and lens tabletting 4, threaded pressure ring 5 is installed by knob mode, realizes lens
2 fixation.The fixation of lens 2, simple structure, high reliability, without adopting are realized by the cooperation of threaded pressure ring 5 and installation screw thread
With screw, production cost is can be effectively reduced in other fixed forms such as glue.In addition, when needing to dismantle lens module
When, since the present invention is using lens module is rotatably mounted, relative to needing to use unloading screw in existing scheme, remove glue
The modes such as water carry out the disassembly of lens module, and the present invention is only needed through rotation threaded pressure ring, energy easy removal lens module,
Realize the purpose of portable disassembly lens module.
Lens tabletting 4 is arranged between lens 2 and threaded pressure ring 5, is used for compensator or trimmer pressure, lens 2 is avoided to be subject to crushing, and improves
The reliability of product.Lens tabletting 4 is cyclic structure, is provided with the pressure that multiple pairs of lens 2 play pressure pair and fixed function
Pawl.In the present embodiment, there are three claw is total to, each claw is arranged equally spaced at the outer ledge of lens tabletting 4, in this way,
Can farthest dispersive stress, avoid the injury to lens 2；It is also possible to guarantee fixed stability, utmostly
Ground prevents lens 2 from shaking.The quantity of its certain claw is not limited to this, or two or three or more, being can be with
Implement.
Lens tabletting 4 is connected to the bottom of lens 2.The inner ring of sealing ring 3 fits with lens 2, the outer ring of sealing ring with
Shell 1 fits, and upper surface and the lens tabletting 4 of sealing ring 3 fit, so that interior of shell and external environs,
Dustproof effect is played, and realizes sealing effect.It should be noted that the upper surface of sealing ring described herein deviates from for sealing ring
One side surface of lens.
The beneficial effects of the present invention are: being in contrast to the prior art, the present invention provides a kind of lens module, camera lens mould
Installation screw thread is machined in the mounting hole of group, threaded pressure ring is installed in the mounting hole by knob mode, with fixed and close
Seal the lens.The present invention can be such that lens reach in the case where stablizing fixed effect is fully sealed, to guarantee camera lens mould
