[0007] The principles and advantages of this solution are:
[0008] 1. This solution transfers the goods to the lifting block, which is driven upward by the vertical block, and the lifting block drives the goods upward, so that the goods pass through the side groove and move into the storage box, thereby realizing the storage of the goods; and during the upward movement of the lifting block, the linkage mechanism drives the rotating shaft to rotate, and the rotating shaft drives the guide plate to rotate, so that the wall groove can be blocked to prevent the goods from falling from the wall groove.

In this solution, the staff can use the inclined guide plate to help transfer the goods to the lifting block or help transfer the goods from the lifting block, which reduces the difficulty of the staff in carrying the goods and makes the operation easier; the rotating guide plate can cover the wall groove to prevent the goods from falling from the wall groove.
[0010] Furthermore, the linkage mechanism includes a first rack fixedly connected to both sides of the side groove, and a first gear coaxially connected to both ends of the rotating shaft, and the first rack is located on the movement track of the first gear.
[0011] Through the above arrangement, during the upward movement of the vertical block, the lifting block moves upward, and the lifting block drives the rotating shaft, the first gear, and the guide plate to move upward.

[0012] Furthermore, a connecting groove is provided between the vertical groove and the side groove, a sliding groove is provided on the side wall of the connecting groove, a clamping arm is slidably connected in the sliding groove, and also includes a movable mechanism that drives the clamping arm to move with the movement of the vertical block.
[0013] Through the above arrangement, during the upward movement of the vertical block, the lifting block moves upward, and the lifting block drives the rotating shaft, the first gear, and the guide plate to move upward. The first gear is engaged with the first rack to drive the first gear to rotate, and the first gear drives the rotating shaft to rotate, and the rotating shaft drives the guide plate to rotate, that is, the guide plate rotates in the direction of the goods, so that the guide plate and the goods are offset.
[0014] During the upward movement of the vertical block, the movable mechanism can also drive the clamping arm to move along the path of the slide slot, that is, the clamping arm rotates in the direction of the goods, so that the clamping arm and the goods are pressed against each other.
[0015] Therefore, the goods can be clamped by the clamping arms and the guide plates, that is, the goods can be positioned to prevent the goods from being displaced and colliding, thereby preventing the goods from being damaged.
[0016] Furthermore, the slide groove is an inclined groove, and the distance between the two slide grooves gradually decreases from top to bottom; the movable mechanism includes a transverse groove opened on the side wall of the vertical block, a transverse block slidably connected to the transverse groove, the transverse block is fixed to the clamping arm, and the transverse block can move laterally and vertically in the linkage groove.
[0017] Through the above arrangement, when the vertical block moves upward, the vertical block will also drive the transverse block to move upward, and the transverse block will drive the clamping arm to move along the path of the slide groove. Since the slide groove is an inclined groove, the distance between the two slide grooves gradually decreases from top to bottom, so that the transverse block drives the clamping arm to move horizontally, that is, the clamping arm moves in the direction of the goods.
[0018] Furthermore, a bottom groove is provided at the bottom of the storage box, and side grooves are provided on both sides of the bottom groove, a wedge block is slidably connected in the side groove, and a first spring is provided between the wedge block and the side groove; adjustment grooves are provided on both sides of the side walls of the storage box, and an adjustment block is slidably connected in the adjustment groove; the adjustment groove is communicated with the side groove, and the adjustment block is fixedly connected to the wedge block; a fixing plate is provided between the two vertical blocks, and a double wedge surface block for simultaneously squeezing the two wedge blocks is provided on the fixing plate, and the double wedge surface block can move vertically in the bottom groove; stop grooves for the wedge block to slide into are provided on both sides of the double wedge surface block, and the wedge block and the stop groove are slidably matched.

[0020] During the lateral movement of the wedge block, the wedge block drives the adjusting block to move in the adjusting groove, that is, the adjusting block drives the wedge block to move out of the stop groove.

[0051] The specific implementation process is as follows:
[0052] When in use, the storage box 11 is placed on the ground through the support column 12 , that is, the storage box 11 is supported by the support column 12 .
[0053] The staff can use the inclined guide plate 26 to help the goods 90 be transferred to the lifting block 23 or to help the goods 90 be transferred away from the lifting block 23, thereby reducing the difficulty of the staff in carrying the goods 90 and making the operation easier.
[0054] Start the cylinder 28, and the output shaft of the cylinder 28 drives the vertical block 22 to move upward, and the vertical block 22 drives the lifting block 23 to move upward, thereby driving the goods 90 to move upward.

[0055] During the upward movement of the lifting block 23, the lifting block 23 drives the rotating shaft 25, the first gear 41, and the guide plate 26 to move upward, the first gear 41 is engaged with the first rack 40 to drive the first gear 41 to rotate, the first gear 41 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the guide plate 26 to rotate in the groove 24 and the wall groove, that is, the guide plate 26 rotates in the direction of the goods 90. When the lifting block 23 stops, the first gear 41, the rotating shaft 25 and the guide plate 26 also stop, and at this time the guide plate 26 is against the goods 90.
[0056] During the upward movement of the vertical block 22, the vertical block 22 will also drive the transverse block 54 to move upward, and the transverse block 54 will drive the clamping arm 52 to move along the path of the slide groove 51. Since the slide groove 51 is an inclined groove, the distance between the two slide grooves 51 gradually decreases from top to bottom, so that the transverse block 54 drives the clamping arm 52 to move horizontally, that is, the clamping arm 52 moves in the direction of the goods 90. When the vertical block 22 stops, the clamping arm 52 is against the goods 90. Therefore, when the vertical block 22 and the lifting block 23 stop, the clamping arm 52 and the guide plate 26 can clamp the goods 90, that is, position the goods 90 to avoid displacement and collision of the goods 90, thereby avoiding damage to the goods 90.
[0057] During the upward movement of the vertical block 22, the vertical block 22 drives the fixed plate 66 to move upward, and the fixed block drives the double wedge surface block 67 to move upward, so that the double wedge surface block 67 squeezes and squeezes the two wedge blocks 62 at the same time, and the two wedge blocks 62 move away, that is, the wedge blocks 62 move into the side groove 61, and the first spring 63 is compressed; the double wedge surface block 67 continues to move upward, so that the two wedge blocks 62 respectively abut against the two sides of the double wedge surface block 67; the double wedge surface block 67 continues to move upward, and when the vertical block 22 stops The two wedge blocks 62 are laterally opposite to the stop grooves 68 on both sides of the double wedge surface block 67, so that the wedge block 62 slides into the stop groove 68 under the action of the first spring 63, thereby realizing the positioning of the double wedge surface block 67, and then realizing the positioning of the two vertical blocks 22, that is, improving the stability of the positioning of the vertical blocks 22; during the lateral movement of the wedge block 62, the wedge block 62 drives the adjustment block 65 to move in the adjustment groove 64, that is, the wedge block 62 can be moved out of the stop groove 68 by the adjustment block 65.
[0058] During the upward movement of the double wedge surface block 67, the double wedge surface block 67 drives the second rack 80 to move upward, so that the second rack 80 is engaged with the second gear 82 to drive the second gear 82 to rotate, the second gear 82 drives the transverse shaft 81 to rotate, the transverse shaft 81 drives the active bevel gear 83 to rotate, the active bevel gear 83 is engaged with the driven bevel gear to drive the driven bevel gear to rotate, the driven bevel gear drives the circular shaft 70 to rotate, and the circular shaft 70 drives the elliptical block 71 to rotate; the double wedge surface block 67 continues to move upward, and when the double wedge surface block 67 is stopped, the two long axis ends of the elliptical block 71 are squeezed respectively. The two panels 75 are pressed to move them apart, and the panel 75 is abutted against the arc block 76, that is, the panel 75 is stopped, so that the two vertical blocks 22 can be simultaneously pressed and limited, and the positioning effect of the vertical blocks 22 is further enhanced; since the panel 75 is an elastic plate, the panel 75 is bent into an arc shape under the action of the arc block 76, that is, the two ends of the panel 75 are in contact with the elliptical block 71, and then the elliptical block 71 is prevented from vertically moving the vertical block 22 through the panel 75 and the arc block 76, and the positioning effect of the vertical block 22 is further enhanced.
[0059] During the lateral movement of the panel 75, the panel 75 drives the movable block 73 to move along the path of the guide groove 72, and the second spring 74 is compressed; the panel 75 continues to move laterally, and when the panel 75 stops, the movable block 73 abuts against the lateral block 54, that is, the abutment against the clamping arm 52 is achieved, thereby strengthening the clamping effect of the clamping arm 52 on the goods 90, and further strengthening the positioning effect on the goods 90.
[0060] After the positioning of the goods 90 is completed, the motor 30 is started, and the output shaft of the motor 30 drives the first drive shaft 31 to rotate, and the first drive shaft 31 drives the first drive gear 36 to rotate, and the first drive gear 36 is engaged with the second drive gear 37 to drive the second drive shaft 32 to rotate, and the second drive shaft 32 pulls the first pull rope 33 to wrap more around the second drive shaft 32, so that the first pull rope 33 drives the storage box 11 to move upward to the specified position through the pull ring 34 and the second pull rope, thereby realizing the transfer of the goods 90; during the upward movement of the storage box 11, the storage box 11 drives the guide rod 39 to move upward synchronously. Since the guide rod 39 moves along the path of the guide groove 38, the guide rod 39 can guide and limit the storage box 11 during the vertical movement, thereby preventing the storage box 11 from shaking.
