[0026] The present invention provides a logo design training display stand, including a console 101, a camera assembly 102 and a lighting assembly 103, wherein the lighting assembly 103 includes a storage shell 104, a threaded rod 105, a first threaded sleeve 106, a movable shell 107, a lighting lamp 108, a driving member 109, a guide member 110 and a lifting member 111, wherein the driving member 109 includes a driving motor 112, a driving gear 113 and a driven gear 114, the guide member 110 includes a guide seat 115 and a guide rod 116, the lifting member 111 includes a bidirectional screw 117, a lifting motor 118, a second threaded sleeve 119 and a rotating rod 120, the rotating rod 120 includes a movable seat 121, a rod body 122 and a fixed seat 123, and the camera assembly 102 includes a bracket 12 4 and a camera 125, the bracket 124 includes a first rotating seat 126, a first telescopic rod 127, a second rotating seat 128 and a second telescopic rod 129, and the lifting and lowering of the illuminating lamp 108 is controlled by the lifting component 111, so that the illuminating lamp 108 can be retracted into the movable shell 107, and the rotation of the threaded rod 105 is controlled by the driving component 109, so that the movable shell 107 can be retracted into the storage shell 104, thereby achieving the purpose of storing the illuminating lamp 108. It can be understood that the above-mentioned scheme can be used in logo design training when it is necessary to display physical objects, documents, pictures, etc., and can also be used to solve the problem that an existing display stand cannot store the illuminating lamp, which makes the illuminating lamp easily damaged by collision during transportation.

[0027] According to this specific embodiment, the camera component 102 is arranged on the console 101. The console 101 is provided with a table top on which physical objects, documents, pictures, etc. can be placed. The camera component 102 converts the image of the object placed on the table into a video signal and inputs it into the projection equipment, thereby conducting logo design training.

[0028] The storage shell 104 is fixedly connected to the console 101 and is located on one side of the console 101. The threaded rod 105 is rotatably connected to the storage shell 104 and is located inside the storage shell 104. The first threaded sleeve 106 is threadedly connected to the threaded rod 105 and is sleeved on the threaded rod 105.

When it is necessary to illuminate the physical object, manuscript, picture, etc., the threaded rod 105 is driven to rotate by the driving member 109, and the rotation of the threaded rod 105 drives the first threaded sleeve 106 moves, so that the first threaded sleeve 106 drives the moving shell 107 to move out of the receiving shell 104. The moving shell 107 is guided by the guide member 110 during the movement. After the moving shell 107 moves out of the receiving shell 104, the lifting member 111 drives the illuminating lamp 108 to move up and down, so that the illuminating lamp 108 moves out of the moving shell 107. At this time, the illuminating lamp 108 is turned on, so that the light emitted by the illuminating lamp 108 can illuminate the object, and can be used for the lifting of the illuminating lamp 108. The lowering component 111 adjusts the height of the lighting lamp 108 for easy use. When the lighting lamp 108 is not in use, the lifting component 111 drives the lighting lamp 108 to retract the movable shell 107, and the driving component 109 starts the threaded rod 105 to reverse, so that the movable shell 107 retracts the storage shell 104, thereby storing the lighting lamp 108, so that the lighting lamp 108 can be stored when not in use, thereby preventing the lighting lamp 108 from being damaged by collision during transportation.

[0029] Secondly, the driving motor 112 is connected to the storage shell 104 and is located inside the storage shell 104; the driving gear 113 is arranged on the driving motor 112 and connected to the output end of the driving motor 112; the driven gear 114 is fixedly connected to the threaded rod 105 and is located on the side of the threaded rod 105 close to the driving gear 113.

[0031] In addition, the bidirectional screw 117 is rotatably connected to the movable shell 107 and is located inside the movable shell 107; the lifting motor 118 is connected to the movable shell 107 and is located inside the movable shell 107, and the output end of the lifting motor 118 is connected to the bidirectional screw 117; the second threaded sleeve 119 is threadedly connected to the bidirectional screw 117 and is sleeved on the bidirectional screw 117; one end of the rotating rod 120 is rotatably connected to the second threaded sleeve 119, and the other end of the rotating rod 120 is rotatably connected to the lighting lamp 108, and the rotating rod 120 is set on the second threaded sleeve 119.

[0032] The movable seat 121 is fixedly connected to the second threaded sleeve 119 and is located on the side of the second threaded sleeve 119 close to the lighting lamp 108; the rod body 122 is rotatably connected to the movable seat 121 and is arranged on the movable seat 121; the fixed seat 123 is fixedly connected to the lighting lamp 108 and rotatably connected to the rod body 122, and is located on the side of the lighting lamp 108 close to the movable seat 121.

[0033] Two second threaded sleeves 119 and two rotating rods 120 are provided in one lighting assembly 103. The thread directions on both sides of the bidirectional screw 117 are opposite. The two second threaded sleeves 119 are respectively located on both sides of the bidirectional screw 117. A limiting block is provided on the second threaded sleeve 119, and a limiting groove is provided on the movable shell 107. The limiting block is located inside the limiting groove, so that the second threaded sleeve 119 can only move but not rotate. When the lighting lamp 108 needs to be used, the lifting motor 118 is started to drive the lifting motor 118 to drive the bidirectional screw 117 to rotate, thereby driving the two second threaded sleeves 119 and the two moving seats 121 to approach each other. In the process of the two moving seats 121 approaching each other, the rod body 122 is driven to rotate, and the lighting lamp 108 is lifted up by the rotation of the two rod bodies 122, thereby achieving the purpose of driving the lighting lamp 108 to rise and fall.

[0034] Finally, the bracket 124 is connected to the console 101 and is located on one side of the console 101 ; the camera 125 is connected to the bracket 124 and is disposed on the bracket 124 .

[0035] The first rotating seat 126 is fixedly connected to the console 101 and is located on one side of the console 101; the first telescopic rod 127 is rotatably connected to the first rotating seat 126 and is set on the first rotating seat 126; the second rotating seat 128 is set on the first telescopic rod 127 and is connected to the output end of the first telescopic rod 127; the second telescopic rod 129 is rotatably connected to the second rotating seat 128, is connected to the camera 125, and is located on one side of the second rotating seat 128.

[0036] The camera 125 converts the image of the object on the table into a video signal, which is then input into the projection equipment for projection. The camera 125 is rotatably mounted on the output end of the second telescopic rod 129. The first telescopic rod 127 and the second telescopic rod 129 can be telescoped, which can increase the shooting range of the camera 125. Through the rotation of the first telescopic rod 127 and the first rotating seat 126, the camera 125 can rotate with the first rotating seat 126 as the center of the circle. Through the rotation connection of the second telescopic rod 129 and the second rotating seat 128, the camera 125 can rotate with the second rotating seat 128 as the center of the circle, thereby facilitating the adjustment of the position of the camera 125 and facilitating shooting.

[0037] When the logo design training display stand of this embodiment is used, when it is necessary to illuminate an object placed on the table of the console 101, the drive motor 112 is started, so that the drive motor 112 drives the active gear 113 to rotate, thereby driving the driven gear 114 and the threaded rod 105 to rotate, so that the rotation of the threaded rod 105 drives the first threaded sleeve 106 to move, so that the first threaded sleeve 106 drives the mobile shell 107 to move out of the storage shell 104, and then the lifting motor 118 is started, so that the lifting motor 118 drives the bidirectional screw 117 to rotate, thereby driving the two second threaded sleeves 119 and the two mobile seats 121 to move against each other. When the two movable seats 121 approach each other, they drive the rod body 122 to rotate. The rotation of the rod body 122 pushes the lighting lamp 108 out of the movable shell 107, so that the lighting lamp 108 can illuminate the objects on the table. When the lighting lamp 108 is not in use, the output ends of the driving motor 112 and the lifting motor 118 are reversed, so that the lighting lamp 108 is retracted into the movable shell 107, and the movable shell 107 is retracted into the storage shell 104. At this time, the lighting lamp 108 is stored, so that the lighting lamp 108 can be stored when not in use, thereby preventing the lighting lamp 108 from being damaged by collision during transportation.
