[0037] Specifically, the telescopic supporting rods 13 are used for connecting the middle layer 11 and the sliding layers 12, so that the sliding layers 12 can move transversely with the middle layer 11 as a base point, when coiled materials are carried, the air cylinder 14 is stretched to drive the sliding layers 12 to move away from the middle layer 11, the sliding layers 12 drive the placing racks 3 to rotate downwards and incline to reduce the height, so that the height of the placing space is synchronously reduced to facilitate the placing or taking out of the coiled materials, and the labor intensity of workers is reduced, after the coiled materials are placed or taken out, the air cylinder 14 is contracted to drive the sliding layers 12 to move to one side of the middle layer 11, so that the length of the cart body 1 is reduced, and the handcart is convenient for workers to move.

[0038] Please refer to the accompanying drawings Figure 3 - the accompanying drawings Figure 5A plurality of protection assemblies 6 are mounted below the connecting layer 4, the protection assembly 6 comprises an inflation member and a plurality of piston cylinders I 621 distributed from top to bottom, the piston cylinders I 621 are fixedly installed on the side wall of the placing rack 3 and are placed on each side of the placing space I, the inside of the piston cylinder I 621 is slidably provided with a piston block I 602, the side wall of the piston block I 602 is fixedly connected with a transversely arranged limiting rod I 603, the surface of the placing rack 3 is provided with an opening for the limiting rod I 603 to pass through, the gas delivery end of the inflation member is connected with the plurality of piston cylinders I 621 through a gas delivery pipe 604, one end of the gas delivery pipe 604 connected with the piston cylinder I 621 is fixedly provided with an air inlet one-way valve 620, the air inlet one-way valve 620 is used to control the one-way flow of gas into the piston cylinder I 621, and the air inlet one-way valve 620 is used to control the one-way flow of gas into the piston cylinder I 621, so that the gas can only enter the piston cylinder I 621 and cannot flow out, thereby ensuring the stable extension of the limiting rod I 603.

[0039] Specifically, after the placing rack 3 loaded with the coiled material is rotated vertically, the inside of the connected piston cylinder is inflated by the inflation member through the gas delivery pipe 604, the piston block I 602 is driven to move by the gas and drives the limiting rod I 603 to pass through the opening, the limiting rod I 603 below the coiled material abuts against the side wall of the coiled material, and the limiting rod I 603 above the coiled material extends above the coiled material, thereby achieving the effect of limiting the coiled material and effectively preventing the coiled material from accidentally falling out of the placing space.

[0040] Embodiment two, please refer to the attached Figure 8 Due to the different diameters of the coiled material and the certain spacing between the limiting rods I 603, the lower surface of the limiting rod I 603 cannot accurately adhere to the upper surface of the coiled material when the limiting rod I 603 extends, so that there may be a gap between the limiting rod I 603 above the coiled material and the coiled material, thereby causing the coiled material to shake when moving. In order to solve this problem, the following scheme is provided in this embodiment, the limiting rod I 603 is fixedly connected with a piston cylinder II 609 above one end of the outside, the inside of the piston cylinder II 609 is slidably provided with a piston block II 606, the bottom end of the piston block II 606 is fixedly connected with a vertically arranged limiting rod II 607, the surface of the limiting rod II 607 inside the piston cylinder II 609 is sleeved with an elastic member I 608, the elastic member can be a steel plate spring, a spiral spring, a torsion bar spring, a rubber spring, etc., and the spiral spring is preferred, the surface of the limiting rod I 603 is provided with a through hole corresponding to the limiting rod II 607, and the center of the limiting rod I 603 and the piston block I 602 is jointly provided with an air inlet channel 610, the air inlet channel 610 is connected with the piston cylinder II 609 through a gas guide pipe 611.

[0041] Specifically, the upward elastic force applied by the elastic member 608 pushes the piston block 606 to slide upward, so that the limiting rod 607 is accommodated in the piston cylinder 609 and the through hole, and the air flow enters the inside of the piston cylinder 609 through the air inlet channel 610 and the air guide pipe 611, and pushes the piston block 606 to slide downward, so that the limiting rod 607 moves downward to abut against the top end of the roll, and the effect of stably limiting the roll is achieved.

The end of the limiting member 615 away from the sealing head 613 is fixedly connected with the inner side wall of the piston cylinder 621, and the length of the limiting member 615 is less than the length of the internal space of the piston cylinder 621.

[0043] Specifically, the elastic member 614 applies an elastic force to the sealing head 613, so that the sealing head 613 is inserted into the inside of the air inlet channel 610 to close the air inlet channel 610. When the limiting rod 603 is stretched, the air inlet channel 610 inside the limiting rod 603 below the roll is closed, so that the limiting rod 607 does not stretch downward. When the limiting rod 603 above the roll is stretched, under the limitation of the limiting member 615, the piston block 602 slides to the end of the piston cylinder 621 close to the placing rack 3, the sealing head 613 is limited by the limiting member 615 to exit and open the air inlet channel 610, so that only the limiting rod 607 above the roll can stretch downward to abut against the top end of the roll for compacting and limiting.

[0053] Specifically, when the vehicle body 1 is unfolded, the sliding layer 12 is away from the intermediate layer 11, the sliding block 72 moves in the sliding groove 8 to the side close to the intermediate layer 11 under the elastic force of the elastic piece five 73, so that the support frame 71 above the sliding block 72 is staggered with the turnover frame 75, and the support frame 71 rotates downward in the direction of the sliding layer 12 under the torsion force of the torsion spring shaft, so as to reduce the height of the support frame 71, avoid that the support frame 71 restricts the workers to carry the coiled material when the support frame 71 is vertical, and cause that the coiled material needs to be carried by lifting, when the vehicle body 1 is contracted, the sliding layer 12 moves close to the intermediate layer 11 and drives the long rod 76 to move close to the limiting protrusion 9, the long rod 76 is limited by the limiting protrusion 9, so that the long rod 76 drives the sliding block 72 to move in the sliding groove 8 to the side of the sliding layer 12, and in the moving process, the support frame 71 is rotated through the turnover frame 75, and the support frame 71 is rotated upward under the limitation of the turnover frame 75 and keeps vertical, and in the subsequent movement, the support frame 71 drives the support wall 74 to abut against the support plate 5, so as to achieve the effect of supporting the support plate 5, thereby dispersing the gravity of the support plate 5 from the coiled material and improving the supporting strength and stability of the support plate 5.

[0054] Working principle: the intermediate layer 11 and the sliding layer 12 are connected through the telescopic support rod 13, so that the sliding layer 12 can move transversely with the intermediate layer 11 as the base point, when the coiled material is carried, the sliding layer 12 is driven away from the intermediate layer 11 by the extension of the air cylinder 14, and the placing frame 3 is rotated downward and inclined to reduce the height when the sliding layer 12 moves, so as to simultaneously reduce the height of the placing space in order to place or take out the coiled material therefrom, thereby reducing the labor intensity of the workers, after the coiled material is placed or taken out, the sliding layer 12 moves to the side of the intermediate layer 11 by the contraction of the air cylinder 14, so as to reduce the length of the vehicle body 1, thereby facilitating the workers to move the trolley.

[0055] After the vertical rotation of the coil-carrying placing rack 3, the inside of the connected piston cylinder is inflated by the inflation member through the gas supply pipe 604, the gas pushes the piston block 602 to move and drives the limiting rod 603 to pass through the opening, the limiting rod 603 below the coil abuts against the side wall of the coil, and the limiting rod 603 above the coil extends above the coil, achieving the effect of limiting the coil and effectively preventing the coil from accidentally falling out of the placing space.

[0056] The bottom end of the sealing member 618 tightly abuts against the inner bottom wall of the shell 617 through the elastic force of the elastic member three 619, so as to close the shell 617 and avoid the gas from flowing out of the shell 617 when the inflation member supplies the gas, then when the coil is placed or taken out, the placing rack 3 rotates downward around the connecting rack 2, so that the bottom end of the sealing member 618 can abut against the connecting rack 2 and rotate upward under the reaction force, thereby opening the shell 617, so that the gas in the inside of the piston cylinder one 621 can be discharged through the exhaust pipe 616, and at this time, the placing rack 3 rotates and tilts, and the limiting rod one 603 and the limiting rod two 607 can be respectively slid and accommodated into the inside of the piston cylinder one 621 and the piston cylinder two 609 under the action of gravity, so as to not limit the coil, so as to facilitate the worker to carry the coil.

[0057] When the vehicle body 1 is unfolded, the sliding layer 12 moves away from the middle layer 11, the sliding block 72 moves to the side close to the middle layer 11 in the sliding groove 8 under the elastic force of the elastic member five 73, so that the support frame 71 above the sliding block 72 is staggered with the turnover frame 75, the support frame 71 rotates downward to the direction of the sliding layer 12 under the torsion force of the torsion spring rotating shaft, thereby reducing the height of the support frame 71, avoiding that the support frame 71 vertically limits the worker to carry the coil, causing the coil to be carried by lifting, when the vehicle body 1 is folded, the sliding layer 12 moves close to the middle layer 11 and drives the long rod 76 to move close to the limiting protrusion 9, the long rod 76 is limited by the limiting protrusion 9, so that the long rod 76 drives the sliding block 72 to move in the sliding groove 8 to the side of the sliding layer 12, and in the moving process, the support frame 71 is rotated through the turnover frame 75, the support frame 71 rotates upward to keep vertical under the limitation of the turnover frame 75, and in the subsequent movement, the support frame 71 drives the support wall 74 to abut against the support plate 5, achieving the effect of supporting the support plate 5, thereby dispersing the gravity of the support plate 5 from the coil, improving the support strength and stability of the support plate 5.
