Wherein, two ends of the roller rod 512 are respectively inserted into the two bases 511, and are fixed on the back plate 3 and the carrying plate 4 together with the two bases 511 to form the roller mechanism 51. The upper end of the backboard 3 is provided with 2 roller mechanisms 51, and the lower end is provided with 1 roller mechanism 51; the lower end of the carrying plate 4 is provided with 1 roller mechanism 51, and the roller mechanisms 51 are symmetrically distributed on the left side and the right side of the carrying mechanism.
One end of the elastic belt 54 is fixed to the mounting plate 4 by an elastic belt pressing piece 55, and then is wound on the roller mechanism 51 at the upper and lower ends in an S-shape in sequence (see the "schematic diagram of the winding structure of the elastic belt"). The end of the elastic band 54 is wound around the outer surface of the sleeve 56, and the nylon string 57 passes through the sleeve 56, and both ends are connected to the rotating shaft 61 at an angle.
The vibration damping adjusting mechanism 6 comprises a rotating shaft 61, a rotating shaft base 62, a one-way bearing 63, a one-way bearing sleeve 64, a clamp spring, a return spring 66 and a handle 67.

The return spring 66 is in clearance fit with the rotating shaft 61, and the handle 67 is screwed on one end of the rotating shaft 61.
The advantage of S-winding the elastic band for 5 turns, as shown in FIG. 4
Since the two sections of elastic bands 54 are symmetrically distributed on the left and right sides of the mounting plate 4, the winding of the elastic band 54 on one side is explained, and the other side is completely the same.

Because the center of gravity of people when walking is up and down fluctuant, the carried heavy objects need to be lifted up when the center of gravity of the human body is raised, and the human body needs to consume a part of energy to do corresponding mechanical work on the heavy objects. The adjustable suspension decompression knapsack mechanism can enable the amplitude generated by the knapsack 1 to be always smaller than the amplitude of the gravity center of a human body, namely, when a person walks carrying heavy objects, the up-and-down motion of the knapsack 1 relative to the ground is reduced, the knapsack 1 is similar to the situation that the knapsack 1 is suspended on the ground and moves along with the human body, so that the mechanical work of the human body on the knapsack 1 is reduced, and simultaneously, the impact load of the straps 2 on the shoulders of the human body during walking can be relieved. The length of the elastic belt is greatly increased by the winding method of S-shaped winding 5 circles, the longer the length of the elastic belt is, the more obvious the suspension effect of the bearing mechanism is, the more obvious the suspension effect is, the better the decompression function of the bearing mechanism can express the effect, and the stability of the human body during walking can be further improved.
When the elastic belt stretches and retracts to drive the backpack 1 to move up and down along the guide rail relative to the backboard, the backpack 1 can realize the suspension pressure reduction function; when a human body travels at normal speed, the amplitude generated by the backpack 1 is always smaller than the amplitude of the gravity center of the human body, so that the stability of the human body during walking is improved, and meanwhile, the arrangement of the elastic belt can relieve the impact load of the backpack 1 on the shoulders of the human body during walking; the suspension decompression effect can be realized under various walking working conditions.
The connection mode between the elastic belt, the nylon rope and the rotating shaft is shown in figures 5 and 6
The end of the elastic belt 54 is wound on the outer surface of the sleeve 56, the nylon rope 57 passes through the sleeve 56, the two ends of the nylon rope penetrate through the corresponding hole positions of the rotating shaft 61 and are connected in an angle (as shown in figure 5), and the structure is symmetrically distributed on the left side and the right side of the bearing mechanism.
This design can effectively solve the stacking problem of the vertical winding of the nylon cord 57. Because, if the nylon string 57 is vertically connected to the rotation shaft 61, the nylon string 57 is stacked when the rotation shaft 61 rotates, thereby reducing the shortened length of the nylon string 57. As is known, the nylon cord 57 is connected to the elastic band 54 through the sleeve 56, and the shortened length of the nylon cord 57 is the extended length of the elastic band 54. When the elastic band 54 is stretched to a small extent, the elastic force is small, and the effect of reducing the pressure by levitation is poor.
The connection mode of the nylon rope 57 and the rotating shaft 61 designed by the invention is angle connection, and two ends of the nylon rope 57 are symmetrically connected on the rotating shaft 61. Such structural design can make nylon rope 57 at the regular winding of winding in-process on pivot 61 to avoided nylon rope 57 to pile up the problem effectively, can also reduce the interval between two boards and prevent to pile up the back and have the interference with two boards, reduced the loss of elastic band 54 elasticity simultaneously, and then increased the suspension decompression effect of bearing the mechanism.
The function principle of the damping adjustment mechanism is shown in figures 7-8
The one-way bearing 63 is engaged with the rotating shaft 61 in two cases (see fig. 9). The two are in close fit at the position of the large and thin shaft section a, and the one-way bearing 63 only acts in one direction, so that the function of returning and locking can be achieved; when the small thin shaft section b is matched, the rotating shaft 61 can rotate freely, and the adjusting function can be achieved.
If the backpack 1 moves the carrying board 4 downward due to the increase of the loaded weight, the user can rotate the handle 67 to drive the rotating shaft 61 to rotate, the inner side of the one-way bearing 63 is tightly fitted with the rotating shaft 61 and is also fixedly connected with the rotating shaft, and there is no relative movement between the two. The design meets the unidirectional rotation of the rotating shaft 61, and the unidirectional rotation of the rotating shaft 61 can ensure that the nylon rope 57 keeps a contraction state all the time, the nylon rope 57 is shortened to pull down the elastic belt 54, the tensile force of the elastic belt 54 is increased, and the carrying plate 4 can be moved up to a balance position, so that the carrying plate 4 is offset from moving down due to the increase of heavy objects.
If the backpack 1 is loaded with less weight, the carrying board 4 moves upward. Because the rotating shaft 61 can move in the axial direction, the rotating shaft 61 can be pulled out by the handle 67, and the rotating shaft 61 drives the one-way bearing 63 to move in the axial direction. At this time, the matching position of the one-way bearing 63 and the rotating shaft 61 is changed from the tight fit of the large thin shaft section a to the small thin shaft section b, so that the rotating shaft can freely rotate in a stepless manner, the rotating shaft 61 in this state can rotate towards the lengthening direction of the nylon rope 57, and then the carrying plate 4 can be adjusted to the balance position by matching with the rotation of the handle 67. The fine adjustment of the handle 68 then cooperates with the return spring 66 which is fitted around the shaft 61 to return the one-way bearing 63 and shaft 61 to a tight fit at the position of the large stub shaft section a, thereby keeping the backpack mechanism in a normal state. Therefore, the position between the load and the human body can be adjusted according to the load quality, and a better bearing effect is achieved.
In conclusion, the bearing mechanism connects the bearing plate and the carrying plate through the vibration damping suspension mechanism, and when the bearing device moves, the sliding block and the sliding rail can reduce the impact of the bearing device on the shoulder under the action of the elastic belt; the vibration reduction adjusting mechanism is connected with the back plate and is connected with the tail end of an elastic belt in the vibration reduction suspension mechanism, and under the condition of different loads, the vibration reduction adjusting effect is achieved by adjusting the length of the elastic belt of the stepless vibration reduction adjusting mechanism. The device can make the knapsack amplitude be less than human amplitude all the time to reduce the impact to the shoulder when carrying the device up-and-down motion, realize the function of knapsack suspension decompression.
