Abstract
The invention discloses a business projector with an adjustable height. The business projector with the adjustable height comprises a base, a projector body, a plurality of limiting stay bars and a plurality of springs. The base comprises a plurality of first grooves and second grooves. According to the business projector with the adjustable height, the purpose of adjusting the height of the projector can be achieved, and stay bar arms, the first grooves and movable rods compose a hollow type triangle so as to guarantee steadiness. The springs can prevent the situation that because the limiting stay bars are not clamped in the playing process, the projector body falls. Besides, when not need, the limiting stay bars of the business projector with the adjustable height can be contained in the first grooves, and when the limiting stay bars are clamped and fixed through buckles, the springs can be stressed and retract to the second grooves; and therefore, the business projector with the adjustable height is easy to operate and convenient to carry.
Description
Technical field
The present invention relates to multimedia technology field, particularly relate to a kind of portable projector.
Background technology
Projector, is a kind of can be connected the corresponding video signal of broadcasting by the different same computers of interface, VCD, DVD, BD, game machine, DV etc. by the equipment on image or VIDEO PROJECTION to curtain.Projector is widely used in family, office, school and public place of entertainment, different according to working method, has CRT, and LCD, DLP etc. are dissimilar.
Nowadays school gives lessons or during working report, selects multimedia tool auxiliary more, and information the most just can convey to each people listened to the teacher, and traditional suspension type projector exists the deficiency that cannot move, so occurring in that all kinds of Portable business projector.And business projector is during using, exists and cannot regulate height, Shortcomings.
Summary of the invention
For solving problem above, the present invention provides a kind of height-adjustable business projector, it is characterised in that include base, projector body, several spacing struts, several springs；
Described base includes several first grooves, the second groove；
Described spacing strut includes strut arm, moving lever, and described strut arm is movably connected with described moving lever, has groove in described moving lever；One end of the most described strut arm is fixedly linked with described projector body, and the other end runs through described groove, and is positioned in described first groove；Described moving lever is stuck in described first groove, along described first concave slot sports；Described projector is connected with described base by described spring, and in a state of use, one end of described spacing strut supports described projector；Described spring is positioned at described second groove, and in its natural state, the length of described spring is more than the degree of depth of described second groove.
It is also preferred that the left described spacing strut also includes that anti-scratch pad, described anti-scratch pad are positioned at one end and the one end of described strut arm being wrapped in described moving lever, the material of described anti-scratch pad is rubber.Described slipmat had both been possible to prevent described moving lever, described strut arm to be moved in playing process, it is impossible to supports described projector body, is possible to prevent again the first groove described in its scratching.
It is also preferred that the left also include several buckles, described projector body includes the 3rd groove matched with buckle；Not being under use state, one end of described buckle is movably connected with described base, and the other end is stuck in described 3rd groove；Described buckle cross section in one direction is in " U " type.When need not use, with described buckle by closely coupled with described base for described projector body, it is convenient for carrying.
It is also preferred that the left each described buckle also includes that scratch resistant pad, described scratch resistant pad are wrapped in one end of described buckle, described scratch resistant pad prevents described buckle from scratching described projector body, affects attractive in appearance.
This height-adjustable business projector that the present invention provides, can reach the purpose regulating described height of projector, in use, mobile described moving lever is to suitable location, moving lever described in subsequently reverse direction bending and the place that is movably connected of described strut arm, described strut arm straps is made to have one end of anti-scratch pad and described first groove joint, described strut arm, described first groove, described moving lever three to combine one hollow type triangle of formation, to ensure steadiness.Described spring can prevent spacing strut described in playing process from failing to block, and causes described projector body to drop, and when this happens, described spring can reach the effect of buffering, the most also can support residence and states projector body.Meanwhile, the described spacing strut of this height-adjustable business projector, when need not use, can be received to described first groove, when fixing with described buckle, described spring is force-applied to be contracted in described second groove, simple to operate, is convenient for carrying.
Accompanying drawing explanation
Fig. 1 is height-adjustable business projector schematic diagram；
Fig. 2 is schematic diagram under spacing strut not use state.
Detailed description of the invention
The height-adjustable business projector of one as shown in Figure 1 and Figure 2, it is characterised in that include base 1,2,2 spacing struts 3 of projector body, several springs 5；
Described base 1 includes several first grooves, the second groove；
Described spacing strut 3 includes that strut arm 6, moving lever 7, described strut arm 6 are movably connected with described moving lever 7, has groove in described moving lever 7；One end of the most described strut arm 6 is fixedly linked with described projector body 2, and the other end runs through described groove, and is positioned in described first groove；Described moving lever 7 is stuck in described first groove, along described first concave slot sports；Described projector is connected with described base 1 by described spring 5, and in a state of use, one end of described spacing strut 3 supports described projector；Described spring 5 is positioned at described second groove, and in its natural state, the length of described spring 5 is more than the degree of depth of described second groove.
Described spacing strut 3 also includes that anti-scratch pad, described anti-scratch pad are positioned at one end and the one end of described strut arm 6 being wrapped in described moving lever 7, and the material of described anti-scratch pad is rubber.Described slipmat had both been possible to prevent described moving lever 7, described strut arm 6 to be moved in playing process, it is impossible to supports described projector body 2, is possible to prevent again the first groove described in its scratching.
Also include that several buckles 4, described projector body 2 include the 3rd groove matched with buckle 4；Not being under use state, one end of described buckle 4 is movably connected with described base 1, and the other end is stuck in described 3rd groove；Described buckle 4 cross section in one direction is in " U " type.When need not use, with described buckle 4, described projector body 2 is closely coupled with described base 1, it is convenient for carrying.
Each described buckle 4 also includes that scratch resistant pad, described scratch resistant pad are wrapped in one end of described buckle 4, and described scratch resistant pad prevents described buckle 4 from scratching described projector body 2, affects attractive in appearance.
These are only preferred embodiment of the present invention, therefore the scope of present invention enforcement can not be limited according to this that the equivalence change i.e. made according to description of the invention content and decoration all should belong in the range of present invention covering.
