[0012] Figure 3 It is Figure 1 the A-A sectional view of DETAILED DESCRIPTION

[0013] As shown in Figures 1-3 , the shoulder pole type backpack device comprises a backboard 2, a support frame 3, a support frame spring sheet pressing plate 4, a spring sheet 6, a connecting frame 7, a connecting frame spring sheet pressing plate 8, and a vibration frame 11.

[0014] The backboard is fastened on the human body by the bandage, and the weight is hung on the vibration frame.

[0015] The support frame is fixed on the backboard by the first screw 1, the support frame spring sheet pressing plate presses the spring sheet on the support frame, and is fastened by the second screw 5.

[0016] The connecting frame is two, is fastened to the left and right sides of the vibration frame by the fourth screw 10 respectively, the left and right ends of the spring sheet are placed on a connecting frame respectively, the two connecting frame spring sheet pressing plates press the two ends of the spring sheet on a connecting frame respectively, and are fastened by the third screw 9.

[0017] Since the backboard of the present application is fastened on the human body by the belt, the weight is hung on the vibration frame, the support frame is fixed on the backboard by the first screw, the spring sheet pressing plate presses the spring sheet on the support frame, and the connection frame is fastened to the left and right sides of the vibration frame by the fourth screw, the left and right ends of the spring sheet are placed on one connection frame respectively, the two ends of the spring sheet are pressed on one connection frame respectively by the spring sheet pressing plate of the two connection frames, and the third screw is penetrated and fastened, so that the function similar to a shoulder pole is formed, the support frame is equivalent to the shoulder of the human body, and the two ends of the spring sheet are equivalent to the front and rear heavy object placing ends of the shoulder pole. When the human body moves (walks, runs, etc.), the spring sheet will vibrate up and down, and the human body is subjected to periodic dynamic load during the carrying process. When the vibration reaches the wave crest, the spring sheet generates upward elastic force to offset part of the weight of the heavy object. When the vibration reaches the wave trough, the weight of the heavy object is pressed on the support frame, and the knee of the human body slowly moves downward with the vibration, which is similar to the movement of the hand along the direction of the ball to catch the ball. Part of the weight of the heavy object can be unloaded, so that the carrying weight can be partially offset or unloaded, and the human body feels relaxed and saves effort when walking with the heavy object.

[0018] Further, as shown in Figure 1 、 2 , the shoulder pole type backpack device further comprises a sliding mechanism, which comprises a sliding block 12, a guide rail 13 and a guide rail support frame 16. One sliding block is installed on the left and right outer sidewalls of the vibration frame, and one guide rail is installed on the backboard near the left and right outer sidewalls of the vibration frame. The two ends of the guide rail are provided with guide rail support frames, which are fixed on the backboard. The sliding block moves up and down linearly on the guide rail, thereby limiting the movement of the vibration frame on the backboard. Such a structure can also prevent the spring sheet from being twisted and broken due to excessive carrying weight.

[0019] Further, the shoulder pole type backpack device can further comprise a cover plate, which covers the outside of the vibration frame and is fixed to the vibration frame by screws. Such a design makes the shoulder pole type backpack device more beautiful and simple in appearance from the outside, and can protect the internal working parts such as the spring sheet and the connection frame, thereby increasing the service life of the backpack device.

[0020] Further, two rectangular holes are formed in the upper part of the backboard, and one rectangular hole is formed in the lower left and right parts of the backboard. The belt is fastened on the human body by penetrating through the rectangular holes. In this way, the shoulder pole type backpack device can be applied to more scenarios of carrying heavy objects. As long as there is a belt and a package, the belt is fastened on the human body by penetrating through the rectangular holes, and the package is filled with heavy objects, the task of transporting heavy objects can be completed.

[0021] Further, the main body of the support frame is block-shaped and fixed in the center of the backboard. The block-shaped design of the main body of the support frame is beneficial to reduce the weight and firmly place the spring sheet.

[0022] Further, the support frame also has a sheet-shaped part extending upward. This design is conducive to fixing the spring sheet, avoiding the spring sheet moving inward or skewing, and ensuring that the spring sheet only performs up-and-down vibration.

[0023] Further, the support frame is two or more, and is evenly distributed on the back plate. Alternatively, a plurality of spring sheets are arranged on one support frame. With this structure, the spring force of the spring sheet can match the gravity of the carried load and the backpack device, preventing the spring sheet from being crushed due to the excessive weight of the load.

[0024] Further, the main body of the support frame spring sheet pressing plate is sheet-shaped, and the front end extends downward to form a baffle 41. The baffle can prevent the spring sheet from moving out of the range of the support frame, avoid the spring sheet moving outward or skewing, and ensure that the spring sheet only performs up-and-down vibration.

[0025] Further, the connecting frame includes a vertical plate, a shelf, and two side plates. The vertical plate is fixed to the vibration frame, the shelf places the spring sheet, and the side plates limit and protect the spring sheet on both sides of the shelf. This structure is also designed to reduce weight.

[0026] Further, the spring sheet is a manganese spring sheet. The manganese spring sheet has high strength, good wear resistance, and low cost, and is very suitable for the use conditions of the backpack.

[0027] In addition, a backpack support plate is arranged, which is fixed to the bottom of the vibration frame by screws, and the backpack is placed on the backpack support plate.

[0028] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application are still within the protection scope of the technical solution of the present application.
