13, backboard 13 is in the right end inside protection box 3, and backboard 13 is being pushed simultaneously, its own is by the second sliding block 15 the
It is slided in two sliding slots 18, and backboard 13 also drives placement plate 2 to slide therewith in first sliding groove 17 by the first sliding block 12
Dynamic, backboard 13 and placement plate 2 are stretched out to the external of protection box 3 always, so that the overturning of dust excluding plate 4 be opened, are placed at the same time
The fixed column 5 that is telescopically connected in 2 bottom of plate is walked slot 16 also by first and is slided with protection box 3, and is telescopically connected to 5 bottom of column
The fixed movable plate 6 in portion is slided on connection sliding slot 21 accordingly also by connection sliding block 7, and movable plate 6 is in the same of sliding
When but also second walks slot 20 and retractable support column 11 and is detached from, after plate 2 to be placed is extend out to greatest extent, can stop sliding
Dynamic, the location hole 19 on movable plate 6 is corresponded to each other with the location hole 19 of the 8 upper end leftmost side of pedestal at this time, can use bolt later
Movable plate 6 is limited to the left end of pedestal 8 through location hole 19 by part, and the position of placement plate 2 is also defined therewith, later
Projector main body 1 can be opened and be come into operation by user；
As shown in Figs. 1-2：If if needing the projection angle to projector main body 1 to be adjusted, can first pull flexible
Spigot on support column 11, retractable support column 11 can stretch according to user's use demand, and retractable support column 11 is being received
When contracting, protection box 3 is flipped up by connecting shaft 10 on support rod 9, and 2 bottom of placement plate is telescopically connected to column 5 at the same time
Also it is stretched, after the completion of the angular adjustment of instrument ontology 1 to be projected, the spigot on retractable support column 11 is retightened therewith, this
When protection box 3 and the angle of placement plate 2 can be defined, conversely, elongation retractable support column 11, protection box 3 then downwardly turn over, and
It driving and is telescopically connected to the contraction of column 5, such setting only needs to adjust the length of retractable support column 11, and it is convenient to use,
The content being not described in detail in this specification simultaneously belongs to the prior art well known to professional and technical personnel in the field.
It can to sum up obtain, this has the office projection instrument storage device for adjusting angle function, passes through the placement of slide construction
The setting of plate 2 and protection box 3 enables projector main body 1 when being placed in placement plate 2 as the sliding of placement plate 2 carries out
It is mobile, to placement plate 2 can be released in protection box 3, when using projector main body 1 so that the camera lens of projector main body 1
It can contact with each other with the external world, in order to project, and placement plate 2 can then be slided completely when not using projector main body 1
The inside of protection box 3 is pushed go back to, and the setting of dust excluding plate 4 and backboard 13 can then play the work of protection to the both ends of protection box 3
With and projector main body 1 can then be protected in protection box 3 well, avoided when idle dust and dirty fallen in projection
On the camera lens of instrument ontology 1, so that projector main body 1 is able to maintain knot even if after not using for a long time only, and pass through sliding
The setting of the movable plate 6 of structure, so that placement plate 2 is in sliding, movable plate 6 can be slided accordingly therewith, so as to
The enough stability for guaranteeing to stretch out placement plate 2 and projector main body 1 inside protection box 3, so that the device is stable when in use
Property it is more preferable, and article can also be placed on movable plate 6, the space on movable plate 6 is utilized well, increased
The practicability of the device, and pass through the setting of connecting shaft 10, enable the protection box 3 to pass through connecting shaft 10 and support rod 9
Between rotated, to change the projection angle of 1 camera lens of projector main body, flexibility is stronger, and adjusting method is more simple
It is single, adjusting appropriate need to be only carried out to the collapsing length of retractable support column 11, it is easy to operate, so that the applicability of the device
More preferably.
