According to the user's needs, the limiting mode is selected. After the sliding box 310 is adjusted, the gas is introduced into the L-shaped air bag 320 to wrap and limit the outside of the material. Then the conveying box 200 is lifted on the rack 100. After lifting in place, part of the gas in the L-shaped air bag 320 is discharged. Then the gas is introduced into the air bag package 220, which is then inflated to drive the lifting plate 210 upward, so that the material moves upward from the conveying box 200 and is in an exposed state, which is convenient for users to take and use, and is more convenient and fast.

[0025] It should be noted that the user can adhere corresponding wear-resistant pads and anti-skid pads to the clamping surface of the L-shaped air bag 320 according to the lifting of the material. The specific selection can be adjusted according to actual needs.

[0026] As shown in Figure 1 , Figure 2 and Figure 3 , the sliding box 310 is bolted to the conveying box 200. Two groups of limiting holes are formed in the conveying box 200, and a group of limiting holes is also formed in the top of the sliding box 310.

[0027] The user can adjust the sliding box 310 to the corresponding position according to the use needs, and then use the bolt to reinforce and install, so as to ensure the stability of the sliding box 310.

[0028] As shown in Figure 2 , Figure 3 and Figure 4 , the bottom of the conveying box 200 is provided with a square tube 230. The inside of the square tube 230 is provided with an electric push rod 240. One end of the electric push rod 240 is provided with a piston plate 250 which is in sliding connection with the inner wall of the square tube 230. The square tube 230 and the sliding box 310 are provided with a hose 231.

[0029] Start the electric push rod 240, and then the piston plate 250 will guide the gas in the square tube 230 into the sliding box 310 along the hose 231. Then the gas enters the L-shaped air bag 320, so that it expands and wraps and limits the material.

[0030] As shown in Figure 2 , Figure 3 and Figure 4 , the air bag package 220 and the square tube 230 are provided with a conduit 221 which passes through the conveying box 200. The bottom of the square tube 230 is provided with an exhaust pipe 232. The outer side of the exhaust pipe 232 and the conduit 221 are both provided with electromagnetic valves.

[0031] When the piston plate 250 moves normally, the electromagnetic valve on the exhaust pipe 232 is opened at this time, and then the piston plate 250 guides the gas in the square pipe 230 into the L-shaped air bag 320, at this time the exhaust pipe 232 inhales the external gas into the square pipe 230, when the piston plate 250 resets, the electromagnetic valve on the guide pipe 221 can be opened, and then the gas in the square pipe 230 can be guided into the air bag 220 along the guide pipe 221, and then the air bag 220 is inflated, and the material lifting operation is performed.

[0032] As shown in Figure 1 The top of the rack 100 is provided with a servo motor 110, the output end of the servo motor 110 is provided with a lead screw 120 through a shaft coupling, one end of the lead screw 120 is rotatably connected to the inside of the rack 100, the inside of the rack 100 is rotatably connected to a limiting rod, the rack 100 is provided with two transmission blocks connected, one side of the transmission block is fixedly connected with the conveying box 200, one end of the lead screw 120 penetrates and is screw-connected to the outside of one transmission block, one end of the limiting rod penetrates and is slidingly connected to the outside of the other transmission block.

[0033] The servo motor 110 is started to operate, the lead screw 120 drives the corresponding transmission block to move up and down, so that the conveying box 200 normally completes the lifting operation, and the setting of the limiting rod can improve the stability of the conveying box 200 during movement, and reduce the phenomenon of accidental deviation and rotation.

[0034] As shown in Figure 1 And Figure 2 The inside of the conveying box 200 is provided with two square rods 260, and the lifting plate 210 is slidingly connected to the outside of the square rod 260.

[0035] The square rod 260 is used to limit the lifting plate 210, so as to reduce the deviation phenomenon during lifting.

[0036] Working principle: the user can put the material to be lifted into the conveying box 200, then the user can adjust the positions of the two sliding boxes 310 according to the size and shape of the material, as Figure 1As shown, two sliding boxes 310 can be synchronously adjusted left and right, or individually adjusted, and at the same time, the front sliding box 310 can be pushed forward and backward, and the limiting mode can be selected according to the needs. After the adjustment of the sliding box 310 is completed, the electric push rod 240 is started, and then the piston plate 250 will guide the gas in the square tube 230 into the sliding box 310 along the hose 231 to wrap and limit the outside of the material. Then the conveying box 200 is lifted on the rack 100, the servo motor 110 is started to operate, which can make the lead screw 120 drive the corresponding transmission block to lift, so that the conveying box 200 normally completes the lifting operation. After lifting in place, the electric push rod 240 can be driven to drive the piston plate 250 to reset, at this time the electromagnetic valve on the conduit 221 can be opened, then the gas in the square tube 230 can be guided into the air bag 220 along the conduit 221, then it is inflated to lift the material, so that the material moves upward from the conveying box 200 and is in an exposed state, which is convenient for users to take and use, and is more convenient and fast. At the same time, the piston plate 250 will extract part of the gas in the L-shaped air bag 320 during the reset movement, canceling the limitation of the material, which is convenient for users to directly take the material. The whole device can change the clamping position and mode during the lifting of the material to clamp different materials, and when the user needs to take out the material, the auxiliary lifting mode can be used to lift the material out, which is convenient for users to take and use.

[0037] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
