It is delivered to projection lens, it is to avoid camera lens is because being deformed by rigidity power.
Another aspect of the invention provides a kind of ultrashort focus projector, including ultrashort focus projector camera lens, described
Ultrashort focus projector lens are fixed by the projector lens fixed structure described in any of the above-described item.
Accompanying drawing explanation
Fig. 1 is this programme projector housing complete machine structure figure；
Fig. 2 is this programme projector lens fixed structure schematic diagram.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
In order to prevent projector lens stress from skew or deformation occurring, the present invention is contemplated that projector lens is solid
Fixed structure uses elastic construction to support, and elastic construction has been effectively isolated rigidity power and has been transferred to camera lens.
Embodiment one:
Projector lens periphery in the present embodiment is provided with shell, generally selects sheet metal component to be coated with projector extremely
Small part camera lens, select sheet metal component as projector lens shell both can be good heat radiation also have relatively simultaneously
Strong mechanical strength, this panel beating mirror head outer shell 20 is connected with bracing frame 10, and bracing frame 10 generally also uses metal plate
Gold part, the bracing frame 10 in present embodiment has two ends, and the first end is fixed with mirror head outer shell 20,
Second end 11 is connected with the support column 40 being fixed on housing 50 by elastic component 30.
By arranging at least one elasticity between the housing and projector housing of projector lens in the present embodiment
Fixed structure so that projector when by External Force Acting, elastic fixing structure generation elastic deformation, thus support
Disappear the external force suffered by camera lens, it is ensured that the reliability of camera lens.
In particular, the flexible lens fixed structure of the camera lens in the present embodiment is effectively isolated the transmission of rigidity power
To projector lens, inventor finds that elastic fixing structure fixed position on camera lens has a major impact, logical
Crossing test of many times to confirm, elastic fixing structure is located between two rigid support points of camera lens, these two rigidity
The strong point is generally the direct contact point of mirror head outer shell and projector housing, can effectively eliminate rigidity power.
The effect of elimination rigidity power can be played, outside the fixed structure in this programme is to camera lens for fixed structure simultaneously
The support force of shell 20 is more than the camera lens rigid support point support force to camera lens.So fixing in the present embodiment
Structure can be effectively isolated and eliminate rigidity power.Camera lens is prevented to be subjected to displacement.
The installation convenience of fixed structure can improve production efficiency and product reliability, and this programme is in view of above-mentioned
Problem, is preset with through hole on mirror head outer shell 20, the first end being connected with mirror head outer shell 20 by bracing frame 10
On be provided with projection, above-mentioned projection can be inserted in through hole, facilitates the connection of bracing frame 10 and mirror head outer shell 20.
Second end 11 of bracing frame 10 is connected by elastic component 30 with support column 40, the second end 11 of bracing frame 10
On offer breach, this breach can be the semicircular indentations that opening is little, this semicircular indentations can with have
The elastic component of I-shaped section coordinates, and snaps in the periphery mid portion of I-shaped elastic component, is engaged in elasticity
Part, owing to elastic component 30 is hollow structure, when semicircular indentations snaps in elastic component 30 periphery, extruding elasticity
Part 30 produces deformation, after semicircular indentations blocks completely such as elastic component 30 periphery, then by screw 60 by bullet
Property part is fixed on support column 40, in order to prevent elastic component 30 from slipping from screw 60, screw 60 He
Packing ring 61 is prevented, to be fixed on support column 40 by elastic component 30 reliably between elastic component 30.Screw
60 by being not only effectively fixed elasticity after the hollow space of elastic component 30, and year filled by screw simultaneously
Hollow space, it is possible to prevent the second end 11 of the semicircular indentations bracing frame 10 that opening is little from slipping.
When bracing frame 10 is fixed between mirror head outer shell 20 and support column 40, this bracing frame 10 can occur shape
Becoming, its first end tightly supports mirror head outer shell, and the second end 11 tightly supports elastic component 30, and thus bracing frame 10 also has
Elasticity, can further isolate rigid elastic power and be transferred to lens case.Fixed structure in this programme sets
Seated position is flexible, both sides being arranged on mirror head outer shell 20 that i.e. can be symmetrical, it is also possible to that staggers is arranged on mirror
The both sides of head shell 20, depending on projector may utilize space.
Another aspect of the present invention, it is provided that a kind of ultrashort focus projector, due to ultrashort focus projector camera lens
Externally rigidity power is very sensitive, and the fixed structure in this programme is especially suitable for solving ultrashort focus projector camera lens
Fixing.
To sum up, this programme uses elastic construction to strengthen fixing projector lens, is arranged on support column and bracing frame
Between elastic component be effectively isolated rigidity power and be delivered on camera lens, efficiently solve projector because transport is run
The technical problem that the camera lens that the external rigidity power such as winnow with a dustpan causes is subjected to displacement, it is ensured that the reliability of projector.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to recognize
Determine the application be embodied as be confined to these explanations.Ordinary skill for the application art
For personnel, on the premise of conceiving without departing from the present application, it is also possible to make some simple deductions or replace
Change.
