Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided with reference to fig. 1, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and thus, the protection scope of the present invention can be defined more clearly and clearly.
In order to reduce the impact of a back load backpack on a human body when the human body floats and effectively reduce extra work done by the human body, the embodiment discloses a backpack suspension mechanism, a backpack 1 is fixedly connected on a backpack fixing frame 2, two linear bearings 3 are respectively and fixedly connected on vertical frame plates at two ends of one side, close to the human body, of the backpack fixing frame 2, the linear bearings 3 at the corresponding ends are slidably sleeved on a same hollow optical axis 4, the top ends of the two hollow optical axes 4 are connected through an upper fixing plate 5, the bottom ends of the two hollow optical axes 4 are connected through a first arc-shaped backup plate 6, a second arc-shaped backup plate 7 is movably connected in the middle of the two hollow optical axes 4, a backup plate adjusting stop block 8 connected to the hollow optical axis 4 is respectively arranged at the upper end and the lower end of the joint of the second arc-shaped backup plate 7 and the hollow optical axis 4, an upper connecting spring 9 is arranged between the linear, the lower extreme at hollow optical axis 4 is equipped with adjustable dog 10, is equipped with sub-unit connection spring 11 between adjustable dog 10 and the linear bearing 3 that is located hollow optical axis 4 lower extreme, is equipped with the solid fixed ring of back of the body area 12 below adjustable dog 10, and the back of the body area 13 one end of both sides is connected with the solid fixed ring of the back of the body area 12 of corresponding one side, and the other end is connected with the corresponding one side of second arc backup plate 7.
The backpack strap 13 is a common backpack shoulder strap structure, and the lower end of the backpack strap is provided with a telescopic tensioning buckle (not shown in the specific structure diagram because of the prior art) capable of adjusting the length of the shoulder strap, so that a user can adjust the length according to the self requirement.
An upper connecting spring 9 is sleeved on the hollow optical axis 4 in a sleeving manner, the top end of the upper connecting spring 9 is fixedly connected with the bottom surface of the upper fixing plate 5, and the bottom end of the upper connecting spring is fixedly connected with the top surface of the linear bearing 3.
