It can be understood that the buffer layer 13 is installed near the user. One side of the wrist, so that when the user uses the tensioner 1, the user's wrist can be buffered and protected. The middle layer 12 is arranged between the buffer layer 13 and the installation layer 11, which can further improve the structure of the strap 10. Strength, to prevent damage to the wristband caused by the large force exerted by the user when exercising. At the same time, the thickness of the strap 10 can be increased so as to improve the comfort when the strap 10 is wrapped around the wrist. In addition, the cushioning effect can be further improved to prevent the user's wrist from being damaged due to a large force. For example, the length of the buffer layer 13 can be less than the installation layer 11, and the length of the intermediate layer 12 can be approximately the same as the length of the installation layer 11. Thus, by setting the intermediate layer 12, the installation layer 11 can be easily protected and the structure of the strap 10 can be improved. strength.

The installation layer 11 is arranged on the side of the cushioning layer 13 facing away from the user's wrist, which facilitates the connection of the wristband 100 to other structures through the installation layer 11 and enhances the stability of the connection.

The edges of the layers 12 are connected, so as to enhance the stability of the connection, reduce the difficulty of assembly, and reduce the production cost, and the installation layer 11 and the middle layer 12 are fixed by sewing. That is to say, the installation layer 11 and the middle layer 12 are connected and fixed by sewing, which is convenient to enhance the connection stability between the installation layer 11 and the middle layer 12, and is easy to reduce the overall weight of the wristband 100, thereby enhancing the practicability of the wristband 100.

In some embodiments, one of the middle layer 12 and the cushioning layer 13 is a superfiber skin layer, and the other is a sponge layer. The middle layer 12 can be configured as a microfiber cortex, and the buffer layer 13 can be configured as a sponge layer, or the buffer layer 13 can be configured as a microfiber cortex, and the middle layer 12 can be configured as a sponge layer, that is, the material of the middle layer 12 and the buffer layer 13 can be Flexible selection according to actual usage needs. For example, the middle layer 12 can be configured as a superfiber cortex, and the buffer layer 13 can be configured as a sponge layer, and the superfiber cortex can be a high-density foamed sponge layer of NBR (Nitrile Butadiene Rubber), and the heat resistance of the buffer layer 13 so arranged Good performance, good air tightness, wear resistance and water resistance, and good structural reliability, low density, light weight, and good rebound effect, which can ensure that the buffer layer 13 has a good buffer effect. At the same time, it is easy to process, can reduce the cost, and then facilitates the function of cushioning and protecting the user's wrist. The middle layer 12 can be a suede-like layer. The suede-like layer has the characteristics of strong water absorption, soft texture, strong toughness, strong water absorption, and tear resistance. Therefore, the middle layer 12 can not only improve the structural reliability of the wristband. , when the middle layer 12 is in contact with the user's wrist, the middle layer 12 can also have good skin affinity, which improves the user's experience when using it.

In some embodiments, as shown in FIG. 5 , the buffer layer 13 can be configured as an elliptical structure, so as to increase the surface area of the buffer layer 13, that is, to increase the contact area between the buffer layer 13 and the wrist of the user, and improve the cushioning effect of the buffer layer 13. effect, and the dimension of the longitudinal direction (for example, the left-right direction as shown in Figure 3 ) of the buffer layer 13 is D1, satisfying: 15cm≤D1≤22cm, such as D1=17.8cm, when the dimension D1 of the longitudinal direction of the buffer layer 13 When the value is selected within the above range, it can ensure that the buffer layer 13 has the greatest buffering effect, and at the same time, it can reduce the occupied area and reduce the cost.

And/or, the dimension of the buffer layer 13 in the width direction is D2, which satisfies: 5cm≤D2≤10cm. Such as D2=6.5cm, or D2=8cm, or D2=9cm, when the dimension D2 of the longitudinal direction of the buffer layer 13 satisfies the above value range, it can be ensured that the buffer layer 13 has the greatest buffering effect, and at the same time, the occupancy can be reduced area and reduce costs. Thus, by arranging the buffer layer 13 with this structural size, it is possible to ensure that the buffer layer 13 has the greatest buffering effect while controlling the size of the buffer layer 13,

In some embodiments, referring to FIG. 5 and FIG. 6 , the contour line of the suture 14 is the same as the outer contour shape of the cushioning layer 13 , that is to say, the contour line of the suture 14 may be the same as the outer contour shape of the cushioning layer 13 The oval shape, that is, the suture 14 can be sewn according to the shape of the outer contour of the cushioning layer 13, so that the outer contour of the cushioning layer 13 can be fully sutured through the suture 14, and the cushioning layer 13 can be prevented from falling off or moving. The problem is to enhance the stability of the buffer layer 13. For example, the stitching line 14 may be located on the surface of the buffer layer 13 on the side facing away from the installation layer 11 .

The minimum distance between the suture 14 and the edge of the cushioning layer 13 is D3, which satisfies: 0.5cm≤D3≤0.7mm. For example, D3 = 0.55 cm. When the minimum distance D3 between the suture line 14 and the edge of the buffer layer 13 is taken within the above-mentioned range, the connection stability between the buffer layer 13 and the intermediate layer 12 and the installation layer 11 can be guaranteed, and at the same time, the buffer layer 13 is guaranteed to have Maximum cushioning effect.

At the same time, compared with the setting of a single bar-shaped hole, the force-bearing area of the strap 10 set in this way is larger, which can reduce the impact force and improve the cushioning effect. For example, there may be an accommodation space between the installation layer 11 and the middle layer 12 , a part of the connection belt 20 is located in the accommodation space, and the rest of the connection belt 20 is located outside the accommodation space to facilitate connection with the elastic cord 200 . Thereby, the reliability of attachment of the connection belt 20 and the strap 10 can be further improved.

Further, as shown in FIGS. 1-3 , there may be multiple installation parts 30 and at least include a first installation part 30 and a second installation part 30 . In the description of the present disclosure, "plurality" means two or more. In the width direction of the strap 10 (for example, the up-down direction as shown in FIG. 3 ), the first mounting portion 30 is located outside the first strip-shaped hole 16, and the second mounting portion 30 is positioned outside the second strip-shaped hole 17. . In this way, the positioning can be facilitated, and at the same time, the distance between the first installation part 30 and the second installation part 30 is relatively large, so that the strap 10 can have a larger fixing range.
