[0022] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0023] By rotating the shaft rod and the winding disc on its outer side, the elastic cord is wound up to adjust the tightness. The operation is convenient. The compression spring moves the structural plate downward, and the elastic cord wound around the outer side of the winding disc is fixed by the anti-slip teeth and is not easy to loosen after being fixed. As Figures 1-4 shown, a kind of anti-dropping strap for sports glasses described in the present utility model includes a circular box body 1, a threaded groove 204 and a first sheath 7. The circular box body 1 is rotatably connected with a shaft rod 4 inside through a bearing. A winding disc 5 is fixedly sleeved on the outer side of the shaft rod 4 through a flat key. Elastic cords 10 are fixed at both ends of the winding disc 5 through bolts. One end of the elastic cord 10 is provided with a first fixing component 2. The first fixing component 2 includes a structural block 201 at one end of the elastic cord 10. A mirror frame groove 202 is penetrated and opened inside the structural block 201;

[0024] A second fixing component 3 is arranged on the top of the circular box body 1. The second fixing component 3 includes a cylinder body 301 connected to the top of the circular box body 1 through a threaded groove. A vertical rod 302 is sleeved at the top end of the cylinder body 301. A structural plate 303 is fixed at the bottom end of the vertical rod 302 located inside the cylinder body 301 through a bolt. A compression spring 305 is sleeved on the outer side of the vertical rod 302 at the top of the structural plate 303.

[0025] When in use, when wearing sports glasses, the structural block 201, the elastic cord 10 and the circular box body 1 restrain it. Rotating the shaft rod 4 drives the winding disc 5 to rotate, winds up the elastic cord 10, and adjusts the tightness. The compression spring 305 pushes the structural plate 303 downward to fix the elastic cord 10 wound around the outer side of the winding disc 5.

[0026] Exemplarily, as Figure 3 shown, the present utility model further includes that a rubber sleeve 203 is glued inside the mirror frame groove 202, and a threaded groove 204 is opened on one side of the bottom of the structural block 201 located in the mirror frame groove 202.

[0027] When in use, the rubber sleeve 203 plays a role of filling and anti-slip.

[0028] Exemplarily, such as Figure 1 、 Figure 2 As shown, the present utility model further includes that a docking screw 11 is sleeved at one end of the elastic cord 10 away from the circular box body 1, and the docking screw 11 is connected to the inside of the thread groove 204.

[0029] During use, by screwing the docking screw 11 into the thread groove 204, one end of the elastic cord 10 can be fixed on the structural block 201.

[0030] Exemplarily, such as Figure 2 As shown, the present utility model further includes that a box cover 6 is fixed to one side of the circular box body 1 by bolts, and a first sheath 7 is arranged on one side of the box cover 6.

[0031] During use, the box cover 6 is used to seal the circular box body 1, and the first sheath 7 can prevent the shaft rod 4 from skewing while not affecting its rotation.

[0032] Exemplarily, such as Figure 2 As shown, the present utility model further includes that one end of the shaft rod 4 penetrates through the first sheath 7, and a grinding wheel 8 is fixed to one end of the shaft rod 4 by bolts.

[0033] During use, the setting of the grinding wheel 8 facilitates the user to rotate the shaft rod 4.

[0034] Exemplarily, such as Figure 4 As shown, the present utility model further includes that anti-slip teeth 304 are welded equidistantly at the bottom of the structural plate 303, and a limiting plate 306 is connected to the top end of the vertical rod 302 through a thread groove.

[0035] During use, the setting of the anti-slip teeth 304 plays an anti-slip role and facilitates the fixation of the elastic cord 10, and the setting of the limiting plate 306 facilitates the user to pull the vertical rod 302.

[0036] When the present utility model is in use, the user respectively sleeves the structural block 201 on the sports glasses frame through the spectacle frame groove 202, and the rubber sleeve 203 seals and prevents slipping between the spectacle frame groove 202 and the sports glasses frame to prevent the structural block 201 from falling off the sports glasses;

[0037] The docking screw 11 at one end of the elastic cord 10 is screwed into the thread groove 204 to fix one end of the elastic cord 10 on one side of the structural block 201;

[0038] When wearing the sports glasses, the circular box body 1 is moved to the back of the head, the vertical rod 302 is pulled up, the grinding wheel 8 is held to rotate the shaft rod 4, the rotation of the shaft rod 4 drives the winding disc 5 to rotate, and the elastic cord 10 is wound around the outside of the winding disc 5 to wind it up and adjust the tightness;

[0039] After the vertical rod 302 is released, the compression spring 305 pushes the structural plate 303 downward, and presses the elastic rope 10 wound outside the winding disc 5 through a plurality of anti-slip teeth 304, and is fixed after the tension adjustment. The fixing is firm and will not cause the elastic rope 10 to loosen.
