[0002] A projector is a device that projects images or videos onto a screen for display. Currently, most projectors are fixedly installed upside down on the ceiling and cooperate with a projection screen set on the wall to realize the display of advertising planning videos or images. However, the construction of such facilities is expensive, and it is inconvenient to move and cannot be taken anywhere at will. Therefore, in order to save costs, many companies are equipped with mobile projectors that can be used in multiple scenarios. However, such projectors that are convenient to carry and move generally appear rather dull. Each time it is used, the projection angle needs to be adjusted according to the desktop, and the operability is relatively inflexible. Moreover, each adjustment takes a lot of time, and sometimes auxiliary tools are needed to pad and level, making it very inconvenient to use. In addition, common projector devices do not have a convenient storage structure, resulting in the projector being exposed for a long time when not in use. Due to the accumulation of dust, while reducing the projection effect, it greatly shortens the service life of the projection device. Therefore, the purpose of the utility model is to provide a projector for advertising planning and display. Summary of the Utility Model

[0020] It should be noted that, without conflict, the embodiments in this embodiment and the features in the embodiments can be combined with each other. Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 4 As shown in the figure, the purpose of this embodiment is to make the projector more convenient to move, with adjustable height, and to prevent the lens from getting dusty when not in use. In view of this, a projector for advertising planning and display is provided, including a main body 1. A projection component is arranged above the main body 1, and a mobile support component is arranged below the main body 1. The main body 1 is used to place the lens 109 and the cover 103 of the projector. The projection component is used to project the required images, and the support component is used to support the main body 1 and adjust the height of the main body 1.

[0022] The projection component includes a support rod 107. One end of the support rod 107 is fixedly provided with a housing 108, and a lens 109 is arranged at one end of the inner wall of the housing 108. The support rod 107 of the projection component is used to adjust the angle of the lens 109, support the lens 109, and make the lens 109 more stable. A through hole A is formed through one end of the support rod 107, and a rotating rod B105 is rotatably arranged in the through hole A. Both ends of the rotating rod B105 are rotatably arranged on the side walls of the square groove 102.

[0023] A circular groove 101 is formed on the upper end surface of the main body 1. One end of the circular groove 101 is provided with a square groove 102. A clamping groove 106 is formed at the upper ends of the circular groove 101 and the square groove 102, and a cover 103 is arranged in the clamping groove 106. A circular groove 101 is formed on the main body 1. The circular groove 101 is used to place the lens 109. One end of the circular groove 101 is provided with a square groove 102 for placing the support rod 107. Through holes B are formed on both sides of the inner wall of the square groove 102, and a rotating rod B105 is rotatably arranged in the through holes B. The support rod 107 rotates in the square groove 102 around the rotating rod B105, and the lens 109 will rotate with the rotation of the support rod 107. When the projector is not in use, the support rod 107 and the lens 109 are placed in the circular groove 101 and the square groove 102, and then the cover 103 is clamped in the clamping groove 106 around the rotating rod A104 in the clamping groove 106, so as to prevent the lens 109 from getting dusty.

[0024] The support component includes a support column 2. A cavity is formed inside the support column 2, and a first power source is fixedly arranged inside the cavity. In this embodiment, the first power source preferably adopts a hydraulic rod 202. One end of the piston rod of the first power source is fixedly connected to the lower end face of the main body 1. The support column 2 of the support component is used to support the main body 1. The hydraulic rod 202, which is the first power source, is fixedly arranged inside the cavity formed inside the support column 2. One end of the piston rod of the hydraulic rod 202 is fixedly arranged on the lower end face of the main body 1. When the height of the main body 1 and the lens 109 is not enough, the hydraulic rod 202 can be started. The piston rod of the hydraulic rod 202 drives the main body 1 to move up and down in height to adjust the main body 1 to a suitable height. The support columns 2 are fixed by fixing columns 201 to make the support columns 2 more stable.

[0025] A fixed disk 203 is fixedly arranged on the side wall of the main body 1. A rotating disk 204 is rotatably arranged on the fixed disk 203, and a handle 205 is arranged between the two rotating disks 204. The side wall of the main body 1 is provided with the fixed disk 203. The rotating disk 204 is rotatably arranged on the end face of the fixed disk 203, and the handle 205 is fixedly arranged on the end face of the rotating disk 204. The handle 205 can rotate along with the rotation of the rotating disk 204. When the projector needs to be moved, the handle 205 is rotated to a vertical angle, and then the handle 205 is held by hand to lift the main body 1 and move the main body 1 to a suitable position, which is more convenient and easy.

[0026] The handle 205 is concave-shaped, and the width between the two ends of the handle 205 is greater than the width of the main body 1. The handle 205 is concave-shaped. The handle rotates and is clamped on the side wall and the front and rear ends of the main body 1. The height of the cross bar of the handle 205 when it is vertical is higher than the height of the outer shell 108 when it is upright.

[0027] When the present utility model is specifically used, first place the main body 1 on a horizontal plane, then rotate the cover 103 from the clamping groove 106 along the rotating rod A104 to an open vertical angle, then hold the outer shell 108 in the circular groove 101, and then rotate the outer shell 108 and the lens 109 around the rotating rod B105 on the inner wall of the square groove 102, and then rotate the outer shell 108 and the lens 109 to a vertical angle. Then aim the lens 109 at the projection screen to be projected, and then adjust the angle of the main body 1. After that, start the hydraulic rod 202 in the support column 2. The movement of the piston rod of the hydraulic rod 202 drives the main body 1 to move up and down, and adjust the main body 1 to the most suitable height. When the position where the main body 1 is placed is inappropriate, hold the handle 205 and rotate the handle 205 along the rotating disk 204 on the fixed disk 203 to a vertical angle, then lift the main body 1 with the handle 205 to move the main body 1 to a suitable position, and then rotate the handle 205 back to its original position. When it is no longer in use, use the support rod 107 to rotate the outer shell 108 and the lens 109 around the rotating rod B105, place the outer shell 108 and the lens 109 in the circular groove 101, place the support rod 107 in the square groove 102, then rotate the cover 103 around the rotating rod A104 and snap it into the clamping groove 106, and then hold the handle 205 to lift the projector and move it to a suitable position for placement and storage, which is more convenient.
