Please refer to fig. 1-4, the utility model provides a projection frame, including base 100, the top of base 100 has set firmly the support frame, and the support frame top has set firmly articulated seat 130, and articulated seat 130 top articulates there is articulated piece 140, and first screw hole 131 has all been seted up to articulated seat 130 and articulated piece 140 one side, and first screw hole 131 female connection has first bolt 132, its main aim at: after the angle of articulated seat 130 and articulated piece 140 has been adjusted, it is fixed with articulated piece 140 to rotate first bolt 132 again and make articulated seat 130, the influence of avoiding receiving projector gravity leads to articulated piece 140 to take place the pivoted condition, articulated piece 140 both ends all have set firmly connecting rod 141, the one end that articulated piece 140 was kept away from to two connecting rods 141 all rotates and is provided with connecting block 150, connecting block 150 all sets up the second screw hole 151 that runs through with connecting rod 141, second screw hole 151 female connection has second bolt 152, its main aim at: equally, after rotating connecting block 150 and adjusting the position, it makes connecting block 150 and connecting rod 141 fixed to screw up second bolt 152 again to avoid receiving the influence of projecting apparatus gravity to lead to connecting block 150 to take place the pivoted condition, two connecting block 150 tops have set firmly backup pad 153, and backup pad 153 one side outer wall all has set firmly level gauge 154 with the one end outer wall, its main objective lies in: the two levels 154 can observe the levelness of the support plate 153 in two mutually perpendicular directions, so that the angle of the support plate 153 can be adjusted according to the two levels 154.

The working principle is as follows:

when the projector is used, the projector frame is placed at a proper position, the first bolt 132 and the second bolt 152 are loosened, the support plate 153 is held to enable the hinge block 140 to rotate at the top of the hinge seat 130, the hinge block 140 is rotated according to the level ruler 154 on the outer wall of one end of the support plate 153 until the position of the level ruler 154 is kept horizontal, then the first bolt 132 is screwed, the support plate 153 is held to enable the connecting block 150 to rotate, the connecting block 150 is rotated according to the level ruler 154 on the outer wall of one side of the support plate 153 until the position of the level ruler 154 is kept horizontal, then the second bolt 152 is screwed, and finally the projector is placed at the top of the support plate 153 to be projected.

The support frame that is arranged in the aforesaid to support, in order to make this projection frame can be applicable to the projection of unnecessary height, so the support frame includes sill bar 110, sill bar 110 bottom and base 100 top fixed connection, shifting chute 111 has been seted up at sill bar 110 top, the cylinder has set firmly in shifting chute 111, the pole 120 in the cylinder expansion end has set firmly, interior pole 120 slides in arranging shifting chute 111 in, interior pole 120 top and articulated seat 130 bottom fixed connection, thereby the control cylinder just can adjust the projected height of this projection frame, the practicality of this projection frame has been improved.

Wherein a backup pad 153 for placing the projecting apparatus, in order to avoid taking place the condition of projecting apparatus landing in the projection, backup pad 153 top has set firmly anti-skidding rubber pad to increase the frictional force between projecting apparatus and the backup pad 153, avoid the projecting apparatus landing.

The projector generates heat when being used for a long time, so that the supporting plate 153 is internally provided with a cavity 155, the top of the cavity 155 is provided with a plurality of through long grooves 156, the bottom of the cavity 155 is provided with a pair of through circular grooves 157, and the pair of circular grooves 157 are internally and fixedly provided with a fan 158, so that the fan 158 can cool the projector when the projector is used, and the service life of the projector is prolonged.

In addition, in order to avoid the support plate 153 from rotating due to the gravity of the projector during use, the first bolt 132 and the second bolt 152 need to be screwed, and in order to facilitate use, anti-slip ribs are arranged on the peripheries of the rotating buttons of the first bolt 132 and the second bolt 152, so that the friction between the hand and the first bolt 132 and the second bolt 152 is increased, and the first bolt 132 and the second bolt 152 are convenient to rotate.

In summary, when the projector is used, in order to further prevent the projector from sliding off the projection rack and being damaged, the protective guards 159 are fixedly arranged on the periphery of the top of the supporting plate 153, so as to protect the projector.

When the projector bracket of the embodiment is used specifically, the projector bracket is placed at a proper position, the first bolt 132 and the second bolt 152 are loosened, then the support plate 153 is held so that the hinge block 140 rotates on the top of the hinge base 130, the hinge block 140 is rotated according to the horizontal ruler 154 on the outer wall of one end of the support plate 153 until the position of the horizontal ruler 154 is kept horizontal, then the first bolt 132 is screwed, the support plate 153 is held so that the connection block 150 rotates, the connection block 150 is rotated according to the horizontal ruler 154 on the outer wall of one side of the support plate 153 until the position of the horizontal ruler 154 is kept horizontal, then the second bolt 152 is screwed, the control cylinder adjusts the overall height of the projector bracket, after the height is adjusted, the projector is placed on the top of the support plate 153 for projection, and the power switch of the fan 158 is turned on so that the fan 158 cools the projector.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
