[0017] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment: As shown in the figure, a multi-purpose deceleration backpack module described in the utility model includes a bag body 1, a shoulder strap 2 and a suspension mechanism 3, the bag body 1 and the shoulder strap 2 are respectively connected to the front and back sides of the suspension mechanism 3, and are detachably connected to the suspension mechanism 3, the suspension mechanism 3 is composed of a back plate 4, a floating plate 5 and an elastic component 6, the back plate 4 and the floating plate 5 have a hole in the middle, and the two are slidably connected, wherein the elastic component 6 is fixed on the back plate 4, and its end is fixedly connected to the floating plate 5, the middle part of the back plate 4 is also provided with a reinforcing rib 7, the middle part of the floating plate 5 is provided with a group of rolling wheels 8 located on both sides of the reinforcing rib 7, the back plate 4 and the floating plate 5 are also provided with a limit component 9 to prevent separation on both sides, and the left and right sides of the back plate 4 and the floating plate 5 are provided with a shoulder buckle 10 for connecting the bag body 1 or the shoulder strap 2. When in use, the bag body 1, the shoulder strap 2 and the shoulder strap buckle 10 are connected and fastened, so that the bag body 1 and the shoulder strap 2 are located on both sides of the suspension mechanism 3. Specifically, the bag body 1 can be fixed on the floating plate 5, and the shoulder strap 2 can be fixed on the back plate 4. The elastic component can be used to make the sports shoulder strap 2 elastically float, so that during the ups and downs movement, the elastic component 6 can be used to offset part of the gravity to achieve a labor-saving suspension effect, relieve the force on the user's shoulders and reduce the weight of the body.

[0019] The elastic component 6 includes a set of fixed pulleys 11 located at the upper and lower ends of the back plate 4 and an elastic rope 12 wrapped around the fixed pulley 11. The fixed pulleys 11 are staggered up and down. One end of the elastic rope 12 is fixed on the back plate 4, and the other end is wrapped and fixed to the lower end of the floating plate 5.

[0020] The limiting assembly 9 includes an L-shaped upper slider 13 fixed on the back plate 4, an F-shaped lower slider 14 fixed on the floating plate 5, and a group of rolling wheels 8 located on the F-shaped upper slider, wherein the rolling wheels 8 roll in contact with the outer side of the back plate 4, and the L-shaped upper slider 13 is slidably connected to the F-shaped lower slider 14.

[0021] The back plate 4 is also provided with a sleeve 15 to which the elastic rope 12 is fixed. The back plate 4 is also provided with a tensioning wheel for adjusting the elastic component 6. When connected, the elastic rope 12 is first fixed to one end of the back plate 4, then wound around the tensioning wheel and then wound around the fixed pulley 11 in sequence, and finally the end is fixed to the lower end of the floating plate 5, and the fixed pulley 11 of the elastic rope 12 forms a pulley group, so that a floating effect is formed between the floating plate 5 and the back plate 4. The sleeve 15 can assist in fixing the elastic rope 12, and it is also convenient to replace the elastic rope 12 later, saving costs and increasing service life.

[0022] The floating plate 5 is also provided with a locking piece which is locked with the back plate 4. The locking piece adopts a locking mechanism so that the floating plate 5 and the back plate 4 can be fixedly connected. After the locking piece is released, the two are floatingly connected. It is suitable for use in running or in an environment with large fluctuations and is highly practical.

[0023] The utility model connects the bag body and the shoulder strap detachably on two sides through a suspension component. Under the action of the elastic component, the bag body on the floating plate and the shoulder strap on the back plate can slide up and down. The elastic rope is extended and retracted to buffer the up and down swinging caused by the weight in the backpack. For long-term walking, physical energy loss can be effectively reduced, the burden on the body is alleviated, and the structure is simple and easy to use.

[0024] The above description is only used to illustrate the technical solution of the utility model rather than to limit it.
