Abstract
The invention discloses a portable projector comprising a base, a projector body, four connecting rods and a plurality of springs. The base comprises four first grooves and four second grooves. Each connecting rod comprises a first rod section and a second rod section. Each first rod section comprises a plurality of limiting holes. Each second rod section comprises limiting balls. According to the portable projector, the purpose of adjusting the height of the projector can be achieved through the connecting rods; the springs can prevent the situation that the projector falls in the playing process when the limiting balls are not clamped, and even when the projector falls, the springs can achieve the buffering effect and support the projector body at the same time; besides, when not needed, the connecting rods of the portable projector can be contained in the first grooves, and when the connecting rods are clamped and fixed through buckles, the springs can be stressed and retract to the second grooves; and therefore, the projector 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 portable projector, it is characterised in that include base, projector body, 4 connecting rods, several springs；Described base includes 4 the first grooves, the second groove；Described connecting rod includes the first pole, the second pole；Described first pole includes several spacing holes；Described second pole includes spacing ball；
Described connecting rod is movably connected with described base, and described connecting rod and described first groove match；Described second pole is positioned at inside described first pole, and can move along described first pole；Described spacing ball matches with described spacing hole；Described projector is connected with described base by described spring, and in a state of use, described connecting rod is erect and 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 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 anti-scratch pad, described anti-scratch pad are wrapped in one end of described buckle, described anti-scratch pad prevents described buckle from scratching described projector body, affects attractive in appearance.
Preferably, described connecting rod also includes slipmat, described slipmat is positioned at the top of described second pole, in a state of use, described slipmat is between described projector body and described second pole, described slipmat had both been possible to prevent described connecting rod can not support described projector body, was possible to prevent again projector body described in described connecting rod scratching.
It is also preferred that the left the material of described slipmat is rubber blanket, the coefficient of friction of rubber is big, and not easily shifted, flexibility is good simultaneously.
This portable projector that the present invention provides, described connecting rod can reach the purpose regulating described height of projector, in use, described spacing ball can be pinned, described second pole is stretched to desired height, by in described spacing ball card to the spacing hole for height, reach the purpose of regulation height with this.Described spring can prevent spacing ball 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 connecting rod of this portable 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 portable projector schematic diagram.
Detailed description of the invention
A kind of portable projector as shown in Figure 1, it is characterised in that include base 1,2,4 connecting rods of projector body, 6,2 buckles 7 of several springs；Described base 1 includes 4 the first grooves, the second groove；Described connecting rod includes first pole the 4, second pole 3；Described first pole 4 includes several spacing holes；Described second pole 3 includes 2 spacing balls 5；
Described connecting rod is movably connected with described base 1, and described connecting rod and described first groove match；It is internal that described second pole 3 is positioned at described first pole 4, and can move along described first pole 4；Described spacing ball 5 matches with described spacing hole；Described projector is connected with described base 1 by described spring 6, and in a state of use, described connecting rod is erect and supports described projector；Described spring 6 is positioned at described second groove, and in its natural state, the length of described spring 6 is more than the degree of depth of described second groove.
Described projector body 2 includes the 3rd groove matched with buckle 7；Not being under use state, one end of described buckle 7 is movably connected with described base 1, and the other end is stuck in described 3rd groove；Described buckle 7 cross section in one direction is in " U " type.When need not use, with described buckle 7, described projector body 2 is closely coupled with described base 1, it is convenient for carrying.
Each described buckle 7 also includes that anti-scratch pad, described anti-scratch pad are wrapped in one end of described buckle 7, and described anti-scratch pad prevents described buckle 7 from scratching described projector body 2, affects attractive in appearance.
Described connecting rod also includes slipmat, described slipmat is positioned at the top of described second pole 3, in a state of use, described slipmat is between described projector body 2 and described second pole 3, described slipmat had both been possible to prevent described connecting rod can not support described projector body 2, was possible to prevent again projector body 2 described in described connecting rod scratching.
The material of described slipmat is rubber blanket, and the coefficient of friction of rubber is big, and not easily shifted, flexibility is good simultaneously.
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.
