[0002] The existing cantilever rack is composed of a vertical column and a plurality of supporting arms fixed on one side thereof.

[0003] However, the height of the column is fixed, so the cantilever shelf takes up a large storage space and is inconvenient to carry. The support arm is connected to the column by bolts and nuts. When the height of the support arm needs to be adjusted, the staff needs to use tools to remove the bolts and nuts, then move the support arm to a suitable position, and then fix it with bolts and nuts. The operation is cumbersome, so a portable cantilever shelf with adjustable size is needed to solve the above problems. Utility Model Content

[0006] As a preferred implementation, the limiting ring is arranged above the second gear.

[0007] As a preferred implementation, the first support arm is slidably connected in the limiting hole.

[0008] As a preferred implementation manner, the through slot is opened on the other side of the movable shell, and the position of the through slot corresponds to the positions of the second bearing and the rotating rod.

[0009] As a preferred implementation, the cross-sectional shapes of the fixed shell and the movable shell are both rectangular.

[0010] As a preferred implementation, the second bearing is arranged above the first bearing, and the second support arm is arranged directly above the first support arm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a turntable, a first gear, a second gear, a threaded tube, a threaded barrel, a threaded block, a first support arm and a second support arm. When the turntable is rotated forward, the rotating threaded barrel drives the second support arm to move upward through the threaded block, the movable rod and the movable block. At the same time, the rotating threaded barrel drives the first support arm to move upward synchronously through the threaded tube. The shelf only needs to rotate the turntable to adjust the height of the first support arm and the second support arm. The operation is simple. When the turntable is reversed, the movable block moving downward drives the movable shell to move downward in the fixed shell. At this time, the size of the shelf is reduced, which reduces the storage space of the shelf, so that the shelf can be conveniently carried.

[0013] The utility model provides a limiting hole and a first support arm. Since the first support arm is slidably connected in the limiting hole, the limiting hole can limit the threaded tube through the first support arm, so that the threaded tube will not rotate under the action of rotating the threaded tube, and the threaded tube can drive the first support arm to move smoothly along its axial direction under the action of rotating the threaded tube.

[0021] See also Figure 1-4 The utility model provides a portable cantilever shelf with adjustable size, including a support component 1, an operating component 2, a driving component 3, a first placement component 4, an adjustment component 5 and a second placement component 6. The support component 1 includes a base 11, a fixed shell 12 and a limit hole 13. The upper surface of the base 11 is connected to the fixed shell 12. The limit hole 13 is opened on one side of the fixed shell 12. The operating component 2 includes a rotating rod 21, a rotating disk 22 and a first gear 23. The rotating rod 21 is rotatably connected in the fixed shell 12. The rotating rod 21 is rotated. The two ends are connected to the rotating disk 22 and the first gear 23 respectively. The driving assembly 3 includes a first bearing 31, a threaded barrel 32, a second gear 33, a second bearing 34 and a limiting ring 35. The limiting ring 35 is arranged above the second gear 33. The threaded barrel 32 is clamped in the first bearing 31 and the second bearing 34. The first bearing 31 and the second bearing 34 are connected in the fixed shell 12. By arranging the first bearing 31 and the second bearing 34, the first bearing 31 and the second bearing 34 can limit and fix the threaded barrel 32 in the fixed shell 12.

[0022] The second gear 33 and the limiting ring 35 are connected to the outside of the threaded barrel 32. The second gear 33 is meshed with the first gear 23. By setting the first gear 23 and the second gear 33, the rotating first gear 23 can drive the threaded barrel 32 to rotate in the first bearing 31 and the second bearing 34 through the second gear 33.

[0023] The first placement component 4 includes a threaded tube 41 and a first support arm 42, and the first support arm 42 is slidably connected in the limiting hole 13. By setting the limiting hole 13 and the first support arm 42, since the first support arm 42 is slidably connected in the limiting hole 13, the limiting hole 13 can limit the threaded tube 41 through the first support arm 42, so that the threaded tube 41 will not rotate under the action of rotating the threaded barrel 32, so that the threaded tube 41 can drive the first support arm 42 to move smoothly along its axial direction under the action of rotating the threaded barrel 32;

[0024] The threaded tube 41 is threadedly connected to the outside of the threaded tube 32, and the threaded tube 41 is connected to the first support arm 42. The adjustment component 5 includes a threaded block 51 and a movable rod 52. The threaded block 51 is threadedly connected to the inside of the threaded tube 32, and the upper surface of the threaded block 51 is connected to the movable rod 52. The second placement component 6 includes a movable block 61, a movable shell 62, a through groove 63 and a second support arm 64. The through groove 63 is opened on the other side of the movable shell 62. The position of the through groove 63 corresponds to the position of the second bearing 34 and the rotating rod 21. By setting the through groove 63, when the movable shell 62 moves downward, the movable shell 62 can drive the through groove 63 to move to the second bearing 34 and stand outside the rod, so that the rotating rod 21 and the second bearing 34 will not block the movable shell 62 moving downward, so that the movable shell 62 moving downward can be smoothly stored in the fixed shell 12;

[0025] The top of the movable rod 52 is connected to the movable block 61, the lower surface of the movable block 61 is connected to the movable shell 62, the movable shell 62 is slidably connected in the fixed shell 12, and the cross-sectional shapes of the fixed shell 12 and the movable shell 62 are both set to be rectangular. By setting the movable shell 62 and the fixed shell 12, since the movable shell 62 is slidably connected in the fixed shell 12, the fixed shell 12 can limit the threaded block 51 through the movable shell 62, the movable block 61 and the movable rod 52, so that the threaded block 51 is not easy to rotate under the action of the rotating threaded barrel 32;

[0026] One side of the movable block 61 is connected to the second support arm 64 . The second bearing 34 is disposed above the first bearing 31 . The second support arm 64 is disposed directly above the first support arm 42 .

[0027] The working principle and use process of the utility model are as follows: when the shelf needs to be used, after the shelf is installed in a suitable position, the turntable 22 is rotated, and the rotating turntable 22 drives the threaded cylinder 32 to rotate in the first bearing 31 and the second bearing 34 through the first gear 23 and the second gear 33, and the rotating threaded cylinder 32 drives the threaded block 51 and the threaded tube 41 to move upward synchronously, and the upwardly moving threaded tube 41 drives the first support arm 42 to move upward in the limiting hole 13, and the upwardly moving threaded block 51 drives the movable shell 62 to slide upward in the fixed shell 12 through the movable rod 52 and the movable block 61, and at the same time, the upwardly moving movable block 61 drives the second support arm 64 to move upward, and when the first support arm 42 and the second support arm 64 are adjusted to a suitable height, the turntable 22 is stopped.
