[0035] A cover plate 13 is provided on one side of the support frame 12 close to the storage rack 11, and the rack 14 is located between the cover plate 13 and the support frame 12.

[0036] The cover plate 13 is fixedly installed on one side of the support frame 12 close to the storage rack 11 by screws, and three parallel long strip through holes are provided through the cover plate 13.

[0037] The top end of the support frame 12 is fixedly installed with a top plate 15 by screws, the bottom end of the support frame 12 is welded with a base 16, and universal wheels 17 are fixedly installed at the bottom of the base 16 by screws.

[0038] The top plate 15 is used to make the top of the support frame 12 tilt inward. The universal wheels 17 are used for moving the device.

[0039] The angle adjustment component 2 includes a rotating frame 21 and a guiding frame 22. The rotating frame 21 and the guiding frame 22 are respectively fixedly installed on the front side and the rear side of the storage rack 11. The rotating frame 21 is rotatably connected to the height adjustment component 3, and a limiting connecting rod 24 is slidably connected to the guiding frame 22. The limiting connecting rod 24 is rotatably connected to the height adjustment component 3.

[0040] The rotating frame 21 is welded and installed at the middle parts of the left and right sides of the front surface of the storage rack 11, the guiding frame 22 is welded and installed at the left and right sides of the back surface of the storage rack 11, and the limiting connecting rod 24 is located outside the guiding frame 22.

[0041] The angle adjustment component 2 further includes two rotating shafts 23, and the two rotating shafts 23 are respectively rotatably connected to the rotating frame 21 and the limiting connecting rod 24.

[0042] The angle adjustment component 2 further includes a connecting bolt 25. The tail of the connecting bolt 25 penetrates through the guiding frame 22 and is threadedly connected to the limiting connecting rod 24. The connecting bolt 25 is slidably connected to the guiding frame 22.

[0043] A through hole is provided through the middle of the left and right of the guiding frame 22. The screw rod of the connecting bolt 25 penetrates through the through hole of the guiding frame 22 and is threadedly connected to the limiting connecting rod 24. After tightening the connecting bolt 25, the head of the connecting bolt 25 can cooperate with the limiting connecting rod 24 to clamp the guiding frame 22, thereby restricting the sliding of the connecting bolt 25.

[0044] The height adjustment assembly 3 includes a sliding frame 31, which is rotatably connected to the limit link 24 and the rotating frame 21. Two gears 34 are rotatably installed on the back of the sliding frame 31. The two gears 34 are respectively connected to two racks 14. A braking device is provided between the gears 34 to limit the rotation of the gears 34.

[0045] The rotating shaft 23 is clamped with the sliding frame 31. After the connecting bolt 25 is loosened, the connecting bolt 25 can slide along the through hole of the guide frame 22. At this time, the storage rack 11 can rotate around the rotating shaft 23 through the rotating frame 21, and the limiting connecting rod 24 can rotate around another rotating shaft 23, thereby adjusting the angle of the storage rack 11. After the angle of the storage rack 11 is adjusted to a suitable position, tighten the connecting bolt 25 to fix the angle of the storage rack 11.

[0046] A gear shaft 33 is rotatably mounted in the center of the gear 34 . The gear shaft 33 penetrates the cover plate 13 and is engaged with the sliding frame 31 .

[0047] The two gears 34 do not contact each other, and the gear 34 meshes with the rack 14, so when the gear 34 rotates, it can move along the rack 14. Thus, the sliding frame 31 can move up and down.

[0048] The braking device includes a tooth plate 35 , which is meshed with the two gears 34 at the same time. A movable shaft 36 is provided in the center of the tooth plate 35 , and the movable shaft 36 penetrates the cover plate 13 and is slidably connected to the sliding frame 31 .

[0049] When the toothed plate 35 is meshed with the two gears 34 at the same time, the gears 34 cannot rotate, and thus the sliding frame 31 cannot move.

[0050] When the toothed plate 35 is disengaged from the two gears 34 , the two gears 34 can rotate freely.

[0051] A mounting groove 32 is provided in the center of the sliding frame 31 , and a movable shaft 36 extends into the mounting groove 32 . A return spring 37 is sleeved on the outer side of the head of the movable shaft 36 and located in the mounting groove 32 .

[0052] The two ends of the return spring 37 are respectively against the mounting groove 32 and the movable shaft 36 . Under the elastic force of the return spring 37 , the movable shaft 36 moves toward the bottom of the mounting groove 32 , thereby keeping the toothed plate 35 meshed with the two gears 34 at the same time.

[0053] A limit screw 38 is threadedly installed above the head of the movable shaft 36 . The limit screw 38 passes through the sliding frame 31 and extends to the top of the sliding frame 31 . The limit screw 38 is slidably connected to the sliding frame 31 .

[0054] Applying an outward thrust to the head of the limit screw 38 can drive the movable shaft 36 to move outward, thereby compressing the return spring 37 and driving the toothed plate 35 to disengage from the two gears 34.

[0055] When the external force applied by the head of the limit screw 38 is removed, the tooth plate 35 returns to its original position under the elastic force of the return spring 37 .

[0056] When the operator of this embodiment uses this device, he loosens the connecting bolt 25 and rotates the storage rack 11. At this time, the storage rack 11 rotates around the rotating shaft 23 through the rotating frame 21. At the same time, the connecting bolt 25 slides along the middle through hole of the guide frame 22, so that the limiting connecting rod 24 rotates around the other rotating shaft 23 to achieve the adjustment of the angle of the storage rack 11.

[0057] After the storage rack 11 is rotated to a suitable position, the connecting bolts 25 are tightened, and the connecting bolts 25 cooperate with the limiting connecting rods 24 to clamp the guide frame 22 to fix the angle of the storage rack 11 .

[0058] Applying an outward thrust to the head of the limit screw 38 can drive the movable shaft 36 to move outward, thereby compressing the return spring 37 and driving the toothed plate 35 to disengage from the two gears 34.

[0059] When the toothed plate 35 is disengaged from the two gears 34 , the two gears 34 can rotate freely.

[0060] When the gear 34 rotates, it can move along the rack 14. Thus, the sliding frame 31 can move up and down. The sliding frame 31 moves up and down, and can drive the storage rack 11 to move up and down through the angle adjustment assembly 2.

[0061] After the rack 11 is moved to a suitable height, the external force applied by the head of the limit screw 38 is removed, and the tooth plate 35 returns to its original position under the elastic force of the return spring 37. The tooth plate 35 is meshed with the two gears 34 at the same time, and the gears 34 cannot rotate at this time, so that the sliding rack 31 cannot move, thereby achieving the height fixation of the rack 11.

[0062] The above shows and describes the basic principle, main features and advantages of the utility model.
