[0012] Figure 2 The fastening device of the sports backpack of the utility model is shown in FIG. Figure 2 .

[0013] As shown in the figure: 1. Buckle; 2. Rope storage compartment; 3. Metal buckle; 4. Rotating wheel axle; 5. Limiting groove; 6. Compartment shell; 7. Flip cover; 8. Rope pull slot; 9. Limiting knob; 10. Anti-slip groove. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] See also Figure 1 —2. In an embodiment of the utility model, a fastening device for a sports backpack includes a buckle 1 and a drawstring storage compartment 2. The buckle 1 is fixedly connected to the drawstring storage compartment 2 on one side of the top end. When in use, the buckle 1 can be fixed to the zipper of the backpack, and then the nylon rope in the drawstring storage compartment 2 can be pulled outward, wrapped around the backpack to fix it, and then fastened in the buckle 1 to complete the fastening of the backpack.

[0016] The buckle 1 includes a metal buckle 3, a rotating wheel axle 4 and a limiting groove 5. The front end of the metal buckle 3 is concave in design, and the front end of the metal buckle 3 is rotatably connected to the rotating wheel axle 4. The two sides of the metal buckle 3 are arc-shaped concave in design, and the two sides of the metal buckle 3 are provided with penetrating limiting grooves 5. When the buckle 1 is fixed, the rope can be tied inside the rotating wheel axle 4.

[0017] The rope storage bin 2 includes a bin body shell 6, a flip cover body 7, a rope draw slot 8, a limit knob 9 and an anti-skid groove 10. The top of the bin body shell 6 is rotatably connected to the flip cover body 7 through a rotating shaft. A rope draw slot 8 is opened on the front side of the bin body shell 6, and an opening is opened on one side of the bin body shell 6. The opening is rotatably connected to the limit knob 9 through a spring. A plurality of groups of anti-skid grooves 10 are opened on the surface of the limit knob 9. The interior of the bin body shell 6 is hollow in design. A spring is installed inside the bin body shell 6, and a nylon rope is fixed by the spring. One end of the nylon rope is exposed through the rope draw slot 8. After pulling out the rope, it can be pulled according to the required length. After confirming the length, the limit knob 9 can be rotated so that the limit knob 9 tightens the internal spring to determine the length of the rope. After long-term use, the rope will inevitably become loose and aged and worn. At this time, the flip cover body 7 can be rotated upward to open the rope, and the rope can be replaced or maintained to extend the overall service life.

[0018] The metal buckle 3 can be used in conjunction with the plastic buckle, and the front end of the plastic buckle can be inserted into the metal buckle 3 for combined fixation. When used in conjunction with the plastic buckle, the metal buckle 3 also has the function of a general buckle, and can limit and fix the backpacker's chest or the backpack body.
