Description
Technical field
Field of optical equipment technology is the utility model is related to, refers in particular to a kind of soft or hard mating type letters type projection screen knot
Structure.
Background technology
Projection screen is called projection screen, is generally divided into commercial curtain, domestic screens, engineering curtain, the species of curtain is a lot, is divided into
It is high, medium and low, it can be determined according to occasion situation face.Existing optical projection screen is divided into soft screen layer and hard screen, and existing projection screen is general
More than 100 cun.When projection screen dispatches from the factory, hard screen dispatches from the factory to be overall, due to oversized, transports and register one's residence installation very not
Just, it is fragile, or even can not register one's residence.And soft screen layer is cumbersome, it is necessary to more than two professional techniques when being installed when registering one's residence
Human users install, and waste time and energy.Therefore, tackle existing projection screen to be improved, to solve the above problems.
Utility model content
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of soft or hard knot to the utility model
Mould assembly letters type projection screen structure, it is stretched structure sheaf by setting volume to stretch structure sheaf in soft screen layer back, using volume and realized to soft
The full extension and letters type for shielding layer fold, and solve the transport of projection screen and installation is registered one's residence problem, reduce cost.
To achieve the above object, the utility model is using following technical scheme：
A kind of soft or hard mating type letters type projection screen structure, its include soft screen layer and be arranged at soft screen layer back for
The volume for strutting soft screen layer and soft screen layer being folded as letters type stretches structure sheaf.
As a kind of preferred scheme：It is a solid matrix that the volume, which stretches structure sheaf, is set in compartment on the solid matrix
There are a plurality of lateral trench for being used to reduce folded projection screen resistance.
As a kind of preferred scheme：The volume stretches the laminated structure that structure sheaf is undulate extension, in the sheet knot
Continous way has been alternately distributed raised and groove on structure.
As a kind of preferred scheme：The projection screen structure also includes metal frame, for metal frame and above-mentioned volume to be stretched
The bonded assembly and edge banding frame of structure sheaf combination, the metal frame are arranged at above-mentioned volume and stretch structure sheaf back, and the bonded assembly is set
Between metal frame and volume stretch structure sheaf end, the edge banding frame is sheathed on metal frame and volume is stretched on the outside of structure sheaf end.
As a kind of preferred scheme：The bonded assembly includes the upper VELCRO of detachable combination each other and lower magic
Patch, VELCRO back fixation is stretched on structure sheaf in volume on this, and the lower VELCRO is fixed in metal frame.
As a kind of preferred scheme：The metal frame is Al-alloy metal frame.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme is understood, by setting volume to stretch structure sheaf in soft screen layer back, stretches full extension of the structure sheaf realization to soft screen layer using volume
And letters type folds, the projection screen integrates traditional soft screen layer foldable and hard the advantages of shielding easily stretching, extension, solves traditional soft
Screen layer is not easy to stretch, and the complicated and hard screen dimensions of installation process are big, fragile, be not easy to transport and register one's residence installation the problem of.So as to drop
The production cost and operation selling price of low projection screen, have wide market prospects.
More clearly to illustrate architectural feature and effect of the present utility model, come below in conjunction with the accompanying drawings with specific embodiment pair
It is described in detail.

Embodiment
The utility model as shown in Figure 1 to Figure 3, a kind of soft or hard mating type letters type projection screen structure, includes soft screen layer
10th, volume stretches structure sheaf 20, Al-alloy metal frame 30, bonded assembly 40 and edge banding frame 50, wherein：
It is plastic cement or metal material that the volume, which stretches structure sheaf 20, and it is adhered to the soft back of screen layer 10.On the one hand the volume stretches structure
Layer 20 can be trailed soft screen layer 10 when using projection screen, be played a supporting role, and soft screen layer 10 is stretched as hard screen
Expansion, makes whole projection screen straight and upright smooth；On the other hand, the volume stretches the knot for being provided with structure sheaf 20 and can reducing curling resistance
Structure, so as to drive soft screen layer 10 to be folded as letters.
As the first embodiment, it is a solid matrix that the volume, which stretches structure sheaf 20, is set in compartment on the solid matrix
It is equipped with a plurality of lateral trench 21 for being used to reduce folded projection screen resistance.
As second of embodiment, the volume stretches the laminated structure that structure sheaf 20 is undulate extension, in the sheet
Continous way is alternately distributed projection 22 and the groove 23 for reducing folded projection screen resistance in structure.
The metal frame 30 is used for the structural soundness for further improving whole projection screen；The bonded assembly 40 and edge banding frame 50
Combined for metal frame 30 and above-mentioned volume to be stretched into structure sheaf 20, also, the bonded assembly 40 include it is detachable each other
The upper VELCRO 41 and lower VELCRO 42 of formula combination；When projection screen is installed, metal frame 30 is arranged at above-mentioned volume and stretches structure sheaf 20
Back, the upper back fixation of VELCRO 41 to be stretched on the end of structure sheaf 20 in volume, lower VELCRO 42 is fixed on the end of metal frame 30,
Being bonded to each other for the end of structure sheaf 20 is stretched using be implemented in combination with metal frame 30 and the volume of upper VELCRO 41 and lower VELCRO 42, then will
Edge banding frame 50 is sheathed on metal frame 30 and volume is stretched and both cooperation fastnesses are further improved on the end of structure sheaf 20.
Design focal point of the present utility model is, by setting volume to stretch structure sheaf in soft screen layer back, stretches structure using volume
Layer is realized to be folded to the full extension and letters type of soft screen layer, what the projection screen collection traditional soft screen layer foldable and firmly screen easily stretched
Advantage, solves traditional soft screen layer and is not easy to stretch, and the complicated and hard screen dimensions of installation process are big, fragile, are not easy to transport
With the problem of installing of registering one's residence.So as to reduce the production cost of projection screen and run selling price, before there is wide market
Scape.
It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made
Any restrictions, therefore every foundation the technical essence of the utility model is to any trickle amendment made for any of the above embodiments, equivalent change
