[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: a back brace strap connection structure, including an upper splint 1 for guiding the elastic band 3, the bottom end of the upper splint 1 is inserted with a lower splint 2 for fixing the plug 4, the bottom end of the lower splint 2 is inserted with a plug 4 for fixing the elastic band 3, the bottom end of the upper splint 1 is fixedly connected with an inclined clamping block 13 for guiding the elastic band 3, the top end of the inclined clamping block 13 is provided with an inclined groove 12 for the elastic band 3 to pass through the inclined clamping block 13, the inner wall of the inclined groove 12 is inserted with an elastic band 3 for fixing the back brace, the top end of the lower splint 2 is provided with a through groove 21 for accommodating the inclined clamping block 13, the through groove 21 and the inclined clamping block 13 are adapted to each other. When the lower splint 2 is inserted into the bottom end of the upper splint 1, the inclined clamping block 13 will be clamped into the inside of the through groove 21. There are multiple groups of inclined clamping blocks 13 and through grooves 21, and multiple groups of inclined clamping blocks 13 and through grooves 21 are symmetrically arranged with the center line of the upper splint 1 as the axis of symmetry. When installing the elastic band 3, it is necessary to guide the two ends of the elastic band 3 to pass through the inside of two groups of inclined clamping blocks 13 respectively.

[0030] Refer to Figure 1 - Figure 3, the bottom end of the inclined clamping block 13 is set as an arc surface, so that the damage to the elastic band 3 can be reduced when the elastic band 3 rubs against the ground of the inclined clamping block 13. Multiple groups of inclined clamping blocks 13 and through grooves 21 are arranged in a V shape. The two inclined clamping blocks 13 can obliquely guide the two ends of the elastic band 3 to extend obliquely, so that it can better fit the user's shoulders. A positive clamping block 14 for guiding the folded part of the elastic band 3 is fixedly connected to the bottom end of the upper clamping plate 1 near the central position. A fixing groove 11 for the elastic band 3 to pass through the positive clamping block 14 is arranged at the top end of the positive clamping block 14. The elastic band 3 is inserted into the inner wall of the fixing groove 11. After the two ends of the elastic band 3 pass through the inside of the inclined clamping block 13, the elastic band 3 can be folded and its folded part can be guided to pass through the fixing groove 11. A storage groove 24 for accommodating the elastic band 3 and the plug pin 4 is arranged at the bottom end of the lower clamping plate 2. The storage groove 24 is adapted to the positive clamping block 14. When the lower clamping plate 2 is inserted into the bottom end of the upper clamping plate 1, the positive clamping block 14 will enter the inside of the storage groove 24. The elastic band 3 is inserted into the inner wall of the storage groove 24. After guiding the folded part of the elastic band 3 to pass through the fixing groove 11, it is necessary to continue to guide it through the storage groove 24. A front clamping block 41 for fixing the front end of the plug pin 4 is fixedly connected to the top end of the plug pin 4 near the front end position. A rear clamping block 42 for fixing the rear end of the plug pin 4 is fixedly connected to the top end of the plug pin 4 near the rear end position. Both the front clamping block 41 and the rear clamping block 42 are plastic clamping blocks and have the ability of elastic deformation. They will bend towards the middle position when being squeezed.

[0031] Refer to Figure 1 - Figure 3 , a front clamping groove 22 for accommodating the front clamping block 41 is arranged at the top end of the lower clamping plate 2 near the front end of the storage groove 24. A rear clamping groove 23 for accommodating the rear clamping block 42 is arranged at the top end of the storage groove 24 near the rear end of the storage groove 24. The front clamping groove 22 is adapted to the front clamping block 41, and the rear clamping groove 23 is adapted to the rear clamping block 42. After the folded part of the elastic band 3 passes through the storage groove 24, it is necessary to guide the plug pin 4 to pass through the upper surface of the folded part, and use the front clamping block 41 and the rear clamping block 42 to fix the plug pin 4 at the bottom end of the storage groove 24. A blocking block 43 for fixing the elastic band 3 is fixedly connected to the top end of the plug pin 4 near the front end of the rear clamping block 42. The blocking block 43 is set in a V shape. When the elastic band 3 is fixed inside the storage groove 24 by the plug pin 4, the rear end of part of the elastic band 3 will be stuck at the front end of the blocking block 43. Multiple groups of blocking blocks 43 are arranged. The bottom end of another group of blocking blocks 43 is arranged at the top end of the plug pin 4 near the rear end of the front clamping block 41. Another group of blocking blocks 43 will block the front end of the elastic band 3. Part of the bent elastic band 3 will be fixed at the middle position between the two groups of blocking blocks 43. The inclined groove 12 is inclined, and both long sides of the plug pin 4 are inclined. The included angle between the two inclined grooves 12 is four times the included angle between the two long sides of the plug pin 4. Therefore, when the plug pin 4 is inserted into the inside of the storage groove 24, the bent part of the elastic band 3 will be kept in a flat extended state due to the restriction of the plug pin 3.

[0032] Working principle: When it is necessary to fix the elastic band 3, the lower clamping plate 2 can be inserted into the bottom end of the upper clamping plate 1 first. Then, both ends of the elastic band 3 can be passed through the inclined slots 12. Subsequently, the middle part of the elastic band 3 can be folded and passed through the fixing slot 11. Then, the pin 4 can be inserted into the top end of the folded part of the elastic band 3. Finally, the elastic band 3 can be tightened to drive the pin 4 to align with the bottom end of the storage slot 24. Then, the elastic band 3 can be moved upward to drive the rear clamping block 42 and the front clamping block 41 to be respectively clamped into the inside of the rear clamping slot 23 and the front clamping slot 22. At this time, the pin 4 will be fixed at the bottom end of the lower clamping plate 2, and the elastic band 3 will also be fixed at the bottom end of the lower clamping plate 2.

[0033] When it is necessary to remove the elastic band 3, the two ends of the elastic band 3 can be relaxed first. Then, the middle folded part of the elastic band 3 can be pulled downward to disengage it from the bottom end of the pin 4. Subsequently, the upper clamping plate 1 can be moved upward to disengage it from the top end of the lower clamping plate 2. Then, the front clamping block 41 can be pushed backward to disengage it from the inside of the front clamping slot 22. At this time, the front end of the pin 4 will no longer be fixed, and the pin 4 can be toggled downward to make its front end tilt downward. Then, the pin 4 can be moved forward to disengage the rear clamping block 42 from the rear clamping slot 23. Then, the pin 4 can be removed. Then, the elastic band 3 can be moved upward to disengage it from the fixing slot 11. By further pulling the elastic band 3, its two ends can be driven to disengage from the inside of the inclined slots 12. At this time, the elastic band 3 is removed.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
