[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figure 1-Figure 4 As shown, a data rack comprises: a frame body 1, a placement groove 7 is provided on the front of the frame body 1, a plurality of placement plates 2 are provided in the placement groove 7, a sliding portion is provided between the placement plates 2 and the frame body 1, limiting cavities 8 are provided inside both sides of the frame body 1, rectangular grooves 5 are provided on both sides of the placement groove 7, the placement groove 7 and the limiting cavity 8 are connected to each other through the rectangular groove 5, an adjusting mechanism capable of adjusting the height of the support plate is provided inside the limiting cavity 8, and a limiting mechanism capable of limiting the adjustment mechanism is provided inside the placement plate 2.

[0022] Furthermore, the sliding part includes a sliding groove 3 opened inside the placement groove 7 on the frame 1, and a plurality of sliding blocks 6 are arranged inside the sliding groove 3. The sliding blocks 6 can slide in the sliding groove 3. The sliding blocks 6 are fixedly connected to the placement plate 2. The placement plate 2 can drive the sliding blocks 6 to slide in the sliding groove 3, so as to ensure that the placement plate 2 can move horizontally up and down.

[0023] Furthermore, the adjustment mechanism includes a tooth plate 9 fixed inside the limit cavity 8, and fixed frames 11 are fixed at both ends of the support plate. The fixed frame 11 can slide inside the rectangular groove 5. The fixed frame 11 is connected to a gear 10 through a rotating shaft. The gear 10 and the tooth plate 9 are meshed with each other. When the placement plate 2 moves up and down, the gear 10 will be driven to rotate on the tooth plate 9, thereby realizing the function of changing the height of the placement plate 2.

[0024] Furthermore, the limiting mechanism includes rectangular grooves 4 provided on the front sides of the placement plate 2, and sliding plates 14 sliding inside the rectangular grooves 4. A limiting block 12 is fixed on the sliding plate 14 facing the side of the gear 10. The limiting block 12 penetrates the placement plate 2 and extends to the inside of the fixed frame 11. A groove 15 is provided at the bottom of the sliding plate 14, and a limiting plate 13 is provided inside the groove 15. The limiting plate 13 can slide in the groove 15. A limiting groove 16 is provided at the bottom of the rectangular groove 4, and the limiting plate 13 can be inserted into the limiting groove 16. The sliding plate 14 is slid. When the sliding plate 14 drives the limiting block 12 to be inserted between two teeth of the gear 10, a part of the limiting plate 13 in the groove 15 will fall into the limiting groove 16 due to gravity, and the limiting plate 13 will limit the sliding plate 14.

[0025] Furthermore, the limit block 12 can slide inside the placement plate 2 , and the limit block 12 can be inserted between two teeth of the gear 10 . The limit block 12 will limit the gear 10 , and then limit the placement plate 2 .

[0026] Furthermore, the depth of the groove 15 is deeper than the depth of the limiting groove 16 , and the height of the limiting plate 13 is the same as the depth of the groove 15 , so that the limiting plate 13 can be generally located inside the groove 15 and generally located inside the limiting groove 16 , thereby completing the limitation of the sliding plate 14 .

[0027] Furthermore, a portion of the limiting plate 13 protrudes compared to the sliding plate 14 , so as to facilitate pulling the limiting plate 13 to move up and down.

[0028] Through the above technical solution:

[0029] When in use, pull the limit plate 13 upwards so that the limit plate 13 no longer limits the sliding plate 14, slide the sliding plate 14, so that the sliding plate 14 drives the limit block 12 to no longer limit the gear 10, move the placement plate 2 downwards so that the distance between the two placement plates 2 can accommodate larger materials, slide the sliding plate 14, when the sliding plate 14 drives the limit block 12 to insert between the two teeth of the gear 10, the limit plate 13 in the groove 15 will fall into the limit groove 16 due to gravity, the limit plate 13 will limit the sliding plate 14, the limit block 12 on one side of the sliding plate 14 will limit the gear 10, and then limit the placement plate 2, thereby completing the limiting and fixing function of the placement plate 2.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
