[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the present invention provides a technical solution: a mattress support device for auxiliary unloading, comprising a base plate 1, a moving wheel 2, a limiting plate 3, a slide groove 4, a fixing bolt 5, a handle 6, a rotating shaft 7, a groove 8, a rotating joint 9, a support plate 10, a first motor 11, a movable roller 12, a second motor 13, a connecting shaft 14, a column 15, a conveyor belt 16, a through hole 17, a load-bearing plate 18, an adhesive layer 19, a Velcro 20 and a mattress 21, the outer corners of the base plate 1 are rotatably connected with the moving wheel 2, and the limiting plates 3 are installed on the left and right sides of the moving wheel 2, the inner side of the limiting plate 3 is slidably connected to the base plate 1 through the slide groove 4, and the limiting plate 3 is fixed to the slide groove 4 by the fixing bolt 5, and the slide groove 4 is respectively reserved on the front and rear surfaces of the base plate 1, and the front and rear sides of the handle 6 are rotatably connected to the groove 8 through the rotating shaft 7. The groove 8 is reserved on the left surface of the bottom plate 1, and the upper left end of the bottom plate 1 is connected to the support plate 10 through a rotary joint 9, and a first motor 11 is installed behind the left end of the support plate 10, and movable rollers 12 are respectively arranged at the left and right ends of the upper part of the support plate 10, and a second motor 13 is installed behind the movable roller 12 at the right end, and the front and rear sides of the movable roller 12 are rotatably connected to the column 15 through a connecting shaft 14, and the column 15 is fixed above the support plate 10, and the outer side of the movable roller 12 is wrapped with a conveyor belt 16, and the lower end of the conveyor belt 16 passes through the inside of the through hole 17, and the through hole 17 is opened inside the lower end of the load-bearing plate 18, and the load-bearing plate 18 is fixed above the support plate 10, and the outer surface of the conveyor belt 16 is provided with a sticky layer 19, and the upper part of the sticky layer 19 is connected to the mattress 21 through Velcro 20;

[0025] The limiting plate 3 is arc-shaped, and the radius of the arc-shaped structure is the same as the radius of the moving wheel 2. At the same time, two limiting plates 3 are symmetrically arranged about the vertical axis of the moving wheel 2, which improves the tightness of the connection between the limiting plate 3 and the moving wheel 2. The moving wheel 2 can be fixed by the limiting plate 3 to prevent it from rolling;

[0026] The rear of the limiting plate 3 forms a sliding mechanism with the bottom plate 1 through the sliding groove 4, and the sliding direction of the sliding mechanism is left and right sliding. The limiting plate 3 can slide to make its inner surface fit with the moving wheel 2 to increase the friction force during the rolling process of the moving wheel 2, thereby completing the fixing of the moving wheel 2;

[0027] The lower left end of the support plate 10 forms a flip mechanism with the bottom plate 1 through a rotating joint 9, and the flipping range of the flipping mechanism is 0-90 degrees. The mattress 21 can be made perpendicular to the ground by flipping the support plate 10, so that the user can place the mattress 21 against the wall, which provides convenience for the user to place the idle mattress 21;

[0028] The outer surface of the movable roller 12 and the inner surface of the conveyor belt 16 are both serrated structures, and the two are meshed and connected. At the same time, the thickness of the conveyor belt 16 is equal to the depth of the through hole 17. The conveyor belt 16 can be driven to roll by the rotation of the movable roller 12, thereby conveying the mattress 21 and completing the separation of the mattress 21 from the entire device;

[0029] The thickness of the bearing plate 18 is equal to the diameter of the movable roller 12, which improves the tightness of the connection between the conveyor belt 16 and the bearing plate 18, and the width of the bearing plate 18 is greater than the width of the conveyor belt 16. At the same time, the width of the conveyor belt 16 is equal to the width of the through hole 17, which facilitates the conveyor belt 16 to pass through the inside of the through hole 17;

[0030] The bottom of the mattress 21 forms a disassembly and installation structure with the conveyor belt 16 through the Velcro 20 and the adhesive layer 19, which makes it easy to disassemble the mattress 21.

[0031] When in use, first place the mattress 21 just above the conveyor belt 16, then translate the mattress 21 downward so that the Velcro 20 fits with the adhesive layer 19, thereby completing the installation between the mattress 21 and the entire device. When the mattress 21 needs to be disassembled, the user can first turn the handle 6 outward through the rotating shaft 7, and drag the entire device to the destination through the handle 6. During this process, the moving wheel 2 rolls, thereby completing the movement of the entire device. After the device moves to the designated area, the user can slide the limit plates 3 on the left and right sides of the moving wheel 2 so that the inner surface of the limit plate 3 fits with the moving wheel 2, and fix the limit plate 3 through the fixing bolts 5 to increase the friction force of the moving wheel 2 during the rolling process, thereby completing the fixing of the moving wheel 2 and preventing the entire device from sliding. At this time, the user can connect the entire device to an external power supply and start the first motor 11. At the same time, the support plate 10 rotates, and when it is flipped upward 90° and is perpendicular to the bottom plate 1, the first motor 11 can be closed. The user can start the second motor 13 to drive the movable roller 12 to rotate. Since the movable roller 12 is meshed and connected with the conveyor belt 16, the conveyor belt 16 rolls on its outer side during the rotation of the movable roller 12 to convey the mattress 21 downward. During this process, the Velcro 20 on the inner side of the lower end of the mattress 21 is gradually separated from the adhesive layer 19 on the outer side of the conveyor belt 16. When the bottom of the mattress 21 contacts the ground, the second motor 13 can be turned off. At this time, the user can further separate the mattress 21 from the conveyor belt 16. After the two are completely separated, the first motor 11 is started again to turn the support plate 10 downward by 90° to fit the bottom plate 1. Finally, the device is moved as a whole to the initial position for fixing. This is the use process of the mattress support device for auxiliary unloading. At the same time, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0032] In summary, the mattress support device for auxiliary unloading is rotatably connected to the moving wheels 2 at the outer corners of the bottom plate 1. The user can adjust the position of the device by pushing the device as a whole. This arrangement is convenient for moving the mattress 21 to the designated location in advance. At the same time, the left and right sides of the moving wheel 2 are provided with limit plates 3 of a sliding structure. The limit plates 3 are in an arc-shaped structure. The friction force of the moving wheel 2 during the rolling process can be increased by the fit between the limit plates 3 and the moving wheel 2, thereby completing the fixation of the moving wheel 2 and preventing the entire device from sliding. In addition, a support plate 10 is flipped and connected above the bottom plate 1, and movable rollers 12 are provided at both left and right ends above the support plate 10, and the movable rollers 12 are interconnected by a conveyor belt 16. The user can complete the rolling of the conveyor belt 16 by rotating the movable roller 12, thereby separating the mattress 21 from the entire device and completing the disassembly of the mattress 21, which provides convenience for the user.
