The utility model has the advantages that: simple structure is effective, and equilateral triangle's roof and end support bar cooperation collateral branch fagging have constituteed a stable structure, have prolonged life, and the ball curtain can be installed in the ball curtain mounting groove, and the curb plate is then installed in the curb plate mounting groove, and the louvre setting is on the collateral branch fagging, and the radiating effect is good.
Description
Technical Field
The utility model relates to a ball curtain projection arrangement main frame.
Background
The spherical screen projection technology is a new display technology, and breaks through the limitation that the projection image can only be a plane regular graph in the past. Wherein, the inner ball throwing device can form a coherent integral picture display on the surface of the ball curtain by matching the ball curtain and the high lumen projector.
The ball screen projection device in the prior art is unreasonable in design, poor in heat dissipation effect, unreasonable in relative installation position relation of the projector and the ball screen and the like, so that the using effect is poor, and the service life is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a ball curtain projection arrangement main frame, its purpose aims at overcoming the above-mentioned not enough that prior art exists, realizes rationalization and designs each structure, improves the result of use.
The technical solution of the utility model is as follows: ball curtain projection arrangement main frame, its structure includes the roof, collateral branch fagging and end support bar, wherein the roof is three angles and is the equilateral triangle of fillet, circular shape ball curtain mounting groove is established at the roof center, the top of a lateral support board is do not connected to the three angle of roof, the bottom of three collateral branch fagging is connected with the three angle of the three end support bar of constituteing an equilateral triangle respectively, an isosceles trapezoid's curb plate mounting groove is constituteed with a limit and the end support bar of the roof that corresponds to two adjacent collateral branch faggings, and end support bar length is greater than the length on a limit of roof, evenly be equipped with the louvre on one of them collateral branch fagging.
Preferably, a circle of top steps lower than the top plate are arranged on the circumference of the ball curtain mounting groove.
Preferably, a circle of side steps lower than the side supporting plates are arranged along the edge of the side plate mounting groove.
Preferably, the included angle between the side supporting plates and the bottom supporting plate is 60 degrees.
The utility model has the advantages that: simple structure is effective, and equilateral triangle's roof and end support bar cooperation collateral branch fagging have constituteed a stable structure, have prolonged life, and the ball curtain can be installed in the ball curtain mounting groove, and the curb plate is then installed in the curb plate mounting groove, and the louvre setting is on the collateral branch fagging, and the radiating effect is good.
Drawings
Fig. 1 is a schematic structural diagram of the main frame of the ball screen projection apparatus of the present invention.
In the figure, 1 is a top plate, 2 is a side support plate, 21 is a heat radiation hole, 3 is a bottom support plate, 4 is a ball curtain mounting groove, 41 is a top step, 5 is a side plate mounting groove, and 51 is a side step.
Detailed Description
The present invention will be described in further detail with reference to examples and embodiments.
As shown in fig. 1, ball curtain projection arrangement main frame, its structure includes roof 1, collateral branch fagging 2 and end support bar 3, wherein roof 1 is three angles and is the equilateral triangle of fillet, circular shape ball curtain mounting groove 4 is established at roof 1 center, roof 1 three angle is connected a side support plate 2's top respectively, three collateral branch fagging 2's bottom is connected with the three angle of the three end support bar 3 who constitutes an equilateral triangle respectively, adjacent two collateral branch faggings 2 and a limit and end support bar 3 constitution isosceles trapezoid's of roof 1 that correspond curb plate mounting groove 5, and end 3 length is greater than the length on one side of roof 1, evenly be equipped with louvre 21 on one of them collateral branch fagging 2.
And a circle of top steps 41 lower than the top plate 1 are arranged in the circumferential direction of the ball curtain mounting groove 4.
The side plate mounting groove 5 is provided with a circle of side steps 51 which are lower than the side support plates 2 along the edge.
The included angle between the side supporting plate 2 and the bottom supporting plate 3 is 60 degrees.
According to above structure, equilateral triangle's roof 1 and end support bar 3 cooperation collateral branch backup pad 2 have constituteed a stable structure, and the ball curtain can be installed in the ball curtain mounting groove, and the curb plate is then installed in curb plate mounting groove 5, and preferred top step 41 and side step 51 can improve the stability of connecting, and the projecting apparatus accessible is connected the accessory and is fixed inside ball curtain projection arrangement main frame.
All the above components are prior art, and those skilled in the art can use any model and existing design that can implement their corresponding functions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
