Image device, is convenient for carrying, and saves space and dust-proof effect might as well.
The utility model is achieved through the following technical solutions：
A kind of portable information technical course projection arrangement, to include and set expansion link on base, the base, described to stretch
The top of contracting bar is that telescopic strut is inserted with hollow stem, the hollow stem, and the top of the expansion link sets support frame, described
The rear and front end of support frame upper surface sets c-type chute, and support frame as described above top is set under left and right half chests, the left and right half chests
End face sets the draw runner being engaged with c-type chute, and the top of the telescopic strut sets supporting plate, and the bottom of the supporting plate is set
Cutting is put, the top of the expansion link sets U-shaped fixed block, and the cutting bottom sets screw, the both sides of the U-shaped fixed block
Screw is also provided with portion, the cutting is fixed with U-shaped fixed block by regulating bolt, the regulating bolt passes through cutting and U-shaped
The screw of fixed block is fixed, and the top of the left and right half chests sets handle, and the supporting plate upper surface sets projecting apparatus.
Further, the supporting plate is located at outside the surface of support frame, adjacent two retracting cylinder of the expansion link
Set on retracting cylinder and be also provided with regulating bolt on screw, the screw of the expansion link.
The beneficial effects of the utility model are：Portable information technical course projection arrangement, is convenient for carrying, while being easy to deposit
Put, save the space of storage, it is more convenient to use, and the storage of computer can be with dust-proof effect very well, therefore easy to spread make
With.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Fig. 1-2 is refer to, the utility model provides a kind of portable information technical course projection arrangement, includes base 1,
Expansion link 2 is set on base 1, and the top of expansion link 2 is to be inserted with telescopic strut 4 in hollow stem 3, hollow stem 3, expansion link 2
Top sets support frame 5, and the rear and front end of the upper surface of support frame 5 sets c-type chute 6, and the top of support frame 5 sets left and right half chests 7,
8, the lower surface of left and right half chests 7,8 sets the draw runner 9 being engaged with c-type chute 6, and the top of telescopic strut 4 sets supporting plate 10,
The bottom of supporting plate 10 sets cutting 11, and the top of expansion link sets U-shaped fixed block 12, and the bottom of cutting 11 sets screw 13, U-shaped
Screw 13 is also provided with the both sides of fixed block 12, cutting 11 is fixed with U-shaped fixed block 12 by regulating bolt 14, regulating bolt
14 pass through the screw 13 of cutting 11 and U-shaped fixed block 12 to fix, and the top of left and right half chests 7,8 is set in handle 15, supporting plate 10
End face sets projecting apparatus 16.Supporting plate 10 is located at flexible outside the surface of support frame 5, adjacent two retracting cylinder of expansion link 2
Set on cylinder on screw 13, the screw 13 of expansion link 2 and be also provided with regulating bolt 14.
In use, the height of supporting plate can be adjusted using expansion link, left and right half chests 7,8 is passed through into c-type chute 6 to both sides
The draw runner 9 being engaged is sliped off, and then supports supporting plate upwards by telescopic strut, by cutting 11, U-shaped fixed block 12 with adjusting
The angle of the cooperation regulation projecting apparatus of bolt is saved, therefore the deficiency that projecting apparatus is not installed on room top can be made up, is not made
Used time, expansion link is accepted, may then pass through regulating bolt and fix, left and right half chests 7,8 is passed through into c-type chute 6 to both sides
The draw runner 9 being engaged closes, that is, is convenient for carrying, at the same it is easily stored, save the space of storage.
And the utility model portable information technical course projection arrangement, it is convenient for carrying, at the same it is easily stored, save storage
Space, it is more convenient to use, and the storage of computer can be with dust-proof effect very well, therefore easy to spread use.
