Description
Technical field
This utility model relates to projector curtain frame technical field, a kind of magnetic-type projection
Instrument curtain frame.
Background technology
Projector, also known as scialyscope, be a kind of can be by image or VIDEO PROJECTION to curtain
Equipment, can be by the different same computers of interface, VCD, DVD, BD, game machine, DV
Etc. the corresponding video signal of broadcasting that is connected.Projector is widely used in family, office,
School and public place of entertainment, different according to working method, there is CRT, LCD, DLP etc. are dissimilar.
Traditional projector curtain is fixing on the wall, is frequently encountered and wants but do not have curtain with projection
Situation, projector can move carrying, class hour curtain the most not all right, so some place is used
The most directly replace with white wall when of projection；, white wall and projection screen are compared, and do not carry
High-gain, expands visual angle, improves resolution, enhancing contrast ratio, strengthens color rendition etc. merit
Can, and owing to metope easily pollutes, or the texture of metope itself all can be made to projected picture
Become certain impact；Also have it is noted that white wall does not has " black surround ", do not look down upon this
Individual black surround, it can improve attention and the picture contrast of viewing, it is possible to increase picture self
Visual quality, it also avoid the impact of surrounding simultaneously, these are all that white wall can not substitute projection
The reason of curtain.
Utility model content
Prior art is difficult to meet the needs of people, in order to solve the problem of above-mentioned existence, this reality
A kind of magnetic-type projector curtain frame is proposed with novel.
For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of magnetic-type
Projector curtain frame, including curtain body, support, connecting cross beam and bracket base；Described cloth
Some strong magnets uniformly it are installed with on the dual-side of body；The bottom of described support is fixed
In the centre position of bracket base, in support, it is inserted with interior sliding support, in the outside of support
Upper end, face is provided with fastening screw；On the described medial surface of interior sliding support and the medial surface of support
All offer link slot；The two ends of described connecting cross beam are fixed with union joint；Described union joint is inserted
It is located in link slot；On the bottom surface of described bracket base, universal wheel is installed.
Further, the upper end of described link slot is circular configuration, and lower end is rectangle structure.
Further, described connecting cross beam has two, connects support and interior sliding support respectively.
Further, described union joint is T-shape structure, and the vertical end of this T-shape structure is
Rectangular structure, the horizontal ends of this T-shape structure is cylindrical structure.
Further, described universal wheel has auto-lock function.
Further, magnetic is passed through in described strong magnets and the side of support, the side of interior sliding support
Power connects.
Compared with prior art, this utility model has the advantages that and " moves curtain at random
Cloth is inhaled " it is made up of magnet and mobile brandreth；Mobile brandreth be may move, telescopic, it
Height can be changed according to the size of curtain, separately have plurality of specifications may select；Fill on mobile brandreth
The strength magnet being equipped with, when installing curtain, only need to be bonded in curtain with supporting magnet
On brandreth.
Support is detachable, it is possible to make curtain be reused；Its occupation mode is simple, energy
Enough it is applied on small-scale stage, mobile propaganda board, outdoor advertising movable, has the highest
Practical value；This magnetic-type projector curtain is simple to operate, practical, it is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment
Technical scheme be clearly and completely described, it is clear that described embodiment be only this
The a part of embodiment of utility model rather than whole embodiments.Based in this utility model
Embodiment, those of ordinary skill in the art are obtained under not making creative work premise
All other embodiments, broadly fall into the scope of this utility model protection.
Refer to Figure of description 1-3, in this utility model embodiment, a kind of magnetic-type throwing
Shadow instrument curtain frame, including curtain body 1, support 2, connecting cross beam 3 and bracket base 4；
Some strong magnets 11 uniformly it are installed with on the dual-side of described cloth body 1；Described
The bottom of frame 2 is fixed on the centre position of bracket base 4, is inserted with interior slip in support 2
Support 21, is provided with fastening screw 23 in the lateral surface upper end of support 2；Described interior slip is propped up
The medial surface of frame 21 all offers link slot 22 on the medial surface of support 2；Described connection horizontal stroke
