[0002] Blood flow restriction training, also known as pressurization training, refers to a training method in which the outside of a limb is pressurized by a pressurization device during exercise to occlude venous blood flow while partially occluding the artery to improve the training effect. Currently, the pressurization device is usually an elastic band, and magic tapes are provided at both ends of the elastic band. The elastic band is tied to the limb through the magic tapes. The pressure received by the limb of the trainer is related to the tightness of the binding by the trainer, resulting in inconvenient control of the pressure received by the limb of the trainer, and thus affecting the training effect. In addition, after the current elastic band is tied to the limb, if it is an airbag type elastic band, it will tighten after inflation, resulting in loosening at the binding position, which will also affect the training effect.

[0033] Embodiment 1
[0034] As Figures 1 - 5 shown, this embodiment provides an airbag strap, including an airbag strap body 11. An inflation nozzle is provided on the airbag strap body 11. A flat - annular connecting piece 15 is provided at one end of the airbag strap body 11, and a braided belt 12 is provided at the other end of the airbag strap body 11. Male velcros 13 and female velcros 14 distributed at intervals are provided on one side of the braided belt 12. The braided belt 12 passes through the connecting piece 15 and is folded back to be detachably connected to the male velcro 13 and the female velcro 14. Its structure is simple. In this way, the braided belt can pass through the connecting piece and be adhered by the male velcro and the female velcro to wind the airbag strap body into a ring shape. Since the velcro is not easy to loosen when adhered, and the tightness can also be adjusted flexibly.
[0035] In this embodiment, a plurality of airbag strips arranged in parallel can be provided inside the airbag belt body. The plurality of airbag strips communicate with each other, and an inflation nozzle is provided as a whole. In this way, when the airbag belt body stops bleeding the limb, a plurality of circular tightening ribs can be formed.
[0036] In the above technical solution, a limiting pin 161 perpendicular to the inner hole is provided at the inner hole of the connecting member 15. The braided belt 12 passes through the connecting member 15, and the limiting pin 161 pierces the folded portion of the braided belt 12 for limiting. In this way, after the braided belt passes through the connecting member, the limiting pin can pierce the braided belt for limiting, avoiding the displacement and loosening of the braided belt relative to the connecting member.
[0037] In the above technical solution, a connecting rod 16 is slidably arranged inside the connecting member 15, and the limiting pin 161 is arranged on the connecting rod 16. By arranging the limiting pin on the connecting rod and the connecting rod being slidable relative to the connecting member, the depth of the limiting pin piercing the braided belt can be adjusted at this time, thereby adjusting its limiting effect.
[0038] Preferably, in this embodiment, a plurality of the limiting pins are arranged on the connecting rod, and the plurality of limiting pins are spaced along the length direction of the connecting rod.
[0039] In the above technical solution, sliding blocks 162 are arranged at both ends of the connecting rod 16. Corresponding side walls of the connecting member 15 are provided with sliding grooves 151 that cooperate with the sliding blocks 162, and the sliding blocks 162 extend into the sliding grooves 151 to slidably connect the connecting rod 16 with the connecting member 15. Its structure is simple, and both ends of the connecting rod are slidably connected to the connecting member through the sliding blocks, and its sliding stability is good and it is not easy to get stuck.
[0040] In the above technical solution, a limiting component 17 is arranged on the sliding block 162. The limiting component 17 includes a limiting rod 171 slidably mounted on the sliding block 162, and the sliding direction of the limiting rod 171 on the sliding block 162 is perpendicular to the sliding direction of the sliding block 162. A limiting groove 152 is opened at a position on the side wall of the sliding groove 151 corresponding to the limiting rod 171. The limiting rod 171 can slide to insert one end thereof into the corresponding limiting groove 152. In this way, the position of the sliding block on the connecting member can be limited by the limiting component, and in this way, the position of the connecting rod on the connecting member can be adjusted by the limiting component to adjust the depth of the limiting pin piercing into the braided belt.
[0041] In the above technical solution, the limiting component 17 further includes an elastic member 172. The elastic member 172 is disposed on the sliding block 162, and the elastic force of the elastic member 172 is used to drive the limiting rod 171 to tend to slide closer to the limiting groove 152. In this way, the limiting rod is always tended to slide closer to the limiting groove for limiting under the action of the elastic member. When it is necessary to release the limit, a manual force needs to be applied to drive the limiting rod to slide away from the limiting groove. The elastic member can be a spring. At this time, one end of the elastic member is welded to the limiting rod, and the other end is welded to the sliding block.
[0042] In the above technical solution, the limiting component 17 further includes a control member 173. The control member 173 includes a rotating rod 1731 and a dial rod 1732. Both the rotating rod 1731 and the dial rod 1732 are cylindrical rods. The rotating rod 1731 is arranged along the length direction of the connecting rod 16 and is coaxially rotatably connected to the connecting rod 16. One end of the dial rod 1732 is welded to the end face of the rotating rod 1731, and the axis of the dial rod 1732 is arranged parallel and spaced from the axis of the rotating rod 1731. An activity groove is formed on the limiting rod 171, and a contact surface 1733 is arranged in the activity groove. The contact surface 1733 is located on one side of the dial rod 1732 close to the axis of the rotating rod 1731. The end of the dial rod 1732 away from the rotating rod 1731 is inserted into the activity groove, and its side surface is in contact with the contact surface 1733. Under the action of an external force, the rotating rod 1731 is rotated to drive the limiting rod 171 to slide away from the limiting groove 152, so as to withdraw the limiting rod 171 from the limiting groove 152 and release the limit on the sliding block 162. Its structure is simple, and the limiting rod can be conveniently controlled to limit or release the limit on the sliding block through the rotating rod and the dial rod.
[0043] In the above technical solution, a push plate 174 is arranged on the rotating rod 1731. The push plate 174 is arranged in a direction perpendicular to the rotation axis of the rotating rod 1731. Its structure is simple, so that the rotating rod can be conveniently manipulated through the push plate.
[0044] In this embodiment, the braided belt and the connecting member are double-limited by the magic tape and the limiting component, so that it is not easy to loosen.
