[0047] The present invention provides a promotional rack for enterprise management through improvement and operates in the following manner;

[0048] First: Before use, first place the data rack in an appropriate horizontal position, and improve the stability of the data rack through the counterweight block 3. At the same time, it can also play a better anti-slip protection role through the rubber anti-slip pad 301. Then place the materials to be promoted in the placement frame 4 at the front end of the rack body 1. Five placement frames 4 are provided from top to bottom with a distance of 20 cm between them, and the placement frames 4 are all in a transparent arc shape, which is conducive to placing more enterprise materials and is convenient and fast for placing and taking. Then connect the external power cord 7 to the external power supply;

[0049] Second: During use, the viewer can control the operation of the corresponding motor by pressing the second switch 602 or the third switch 603. The operation of the motor can drive the first bevel gear 606 to rotate clockwise through the output shaft, so that the first bevel gear 606 can drive the second bevel gear 607 to rotate clockwise, and then drive the gear 609 to rotate clockwise through the rotating shaft 608, so that the gear 609 combines with the thread on the screw rod 610 to move the screw rod 610 upward in the guide sleeve 611, thereby lifting the lock block 612 from the lock hole 506, and then opening the folding seat 5, which is beneficial to more firmly fixing and storing the folding seat 5 and solves the problem that the folding seat 5 is not easy to store;

[0050] Third: When the lock block 612 is lifted from the lock hole 506, it can touch the first switch 508, thereby starting the operation of the electric motor 5076. The electric motor 5076 can drive the large gear 5077 to rotate clockwise through the output shaft, so that the large gear 5077 drives the small gear 5078 to rotate counterclockwise, so that the small gear 5078 drives the large pulley 5079 to rotate counterclockwise, so that the large pulley 5079 drives the small pulley 50711 to rotate counterclockwise through the belt 50710, so that the small pulley 50711 drives the rotating shaft 5073 to rotate counterclockwise through the fixed shaft 50712, so that the support feet 5074 rotate downward counterclockwise to expand and support, which is beneficial to achieving a good support effect and is simple and convenient to use, preventing the phenomenon that the seat 501 is complicated to use;

[0051] Fourth: Then turn the folding seat 5 downward and support it stably through the support feet 5074. At the same time, the cushion block 5075 at the bottom of the support feet 5074 can play a role in anti-slip protection. Then turn the backrest 503 upward, and the limit block 504 can play a role in limiting the backrest 503. Then one can sit on the seat 501 and lean on the backrest 503 to browse materials, which is conducive to enabling the browser to browse in a more comfortable way, improving the browsing efficiency and comfort;

[0052] Fifth: After the browsing is over, the user can put the browsing materials back into the placement frame 4, then fold the backrest 503 back to its original position, and fold the folding seat 5 upward back to its original position. Then press the corresponding switch to drive the motor to rotate in the reverse direction, so that the lock block 612 descends and is inserted into the lock hole 506 for closing. At the same time, after the lock block 612 is inserted into the lock hole 506, it can touch the first switch 508, so that the electric motor 5076 rotates in the reverse direction, and the support feet 5074 can be folded downward back to their original positions.

[0053] Through improvement, the present invention provides a promotional rack for enterprise management. When in use, the left or right lock block 612 can be driven to rise through the second switch 602 or the third switch 603, so as to touch the first switch 508, and then drive the support feet 5074 to unfold and then turn down the seat 501, and turn the backrest 503 backward to sit on the seat 501 and lean on the backrest 503 to browse materials. After use, first fold the seat 501 back to its original position, and then drive the left or right lock block 612 to descend and be inserted into the lock hole 506 through the second switch 602 or the third switch 603, and it can touch the first switch 508, and then drive the support feet 5074 to fold downward, solving the problem that the existing promotional rack for enterprise management cannot better facilitate browsers to browse enterprise materials in a more comfortable way, and at the same time, the browsing seat is complex to use and not easy to store.
