[0030] The present invention provides a strap adjustment device 100 .

[0031] Please refer to Figure 1 In an embodiment of the present invention, the fixing belt adjustment device 100 includes:

[0032] A buckle body 10, wherein the buckle body 10 is formed with an adjustment hole 11;

[0033] An adjusting member 30, wherein the adjusting member 30 is located in the adjusting hole 11, and one side of the adjusting member 30 is elastically connected to a peripheral wall of the adjusting hole 11; and

[0034] An adjusting belt 50, wherein the adjusting belt 50 comprises an adjusting section 51 and a connecting section 53, wherein the adjusting section 51 and the connecting section 53 are respectively located on two sides of the adjusting member 30;

[0035] The end of the adjusting member 30 and the peripheral wall corresponding to the adjusting hole 11 are movably connected. The adjusting member 30 squeezes the adjusting section 51 under elastic force. The adjusting member 30 moves to release the adjusting section 51 under manual pressing.

[0036] In this embodiment, the fixing belt adjustment device 100 can be used for equipment that needs to be worn or attached to the human body, such as medical equipment, daily life equipment, etc., to adjust the fixing belt to different sizes according to different human body shapes, thereby improving wearing comfort. Specifically, in this embodiment, the buckle body 10 is plate-shaped, and the shape is approximately rectangular. Of course, in other embodiments, the buckle body 10 can also be block-shaped or strip-shaped, and the shape of the buckle body 10 can also be square, circular or other polygons, etc., which are not limited here. The shape of the adjustment hole 11 of the buckle body 10 is compatible with the shape of the buckle body 10, both of which are rectangular, which effectively improves the utilization rate of the buckle body 10. Of course, the shape of the adjustment hole 11 can also be circular or square, etc.

[0037] The adjusting member 30 is rod-shaped, and the adjusting section 51 and the connecting section 53 are respectively located on both sides of the adjusting member 30, that is, one end of the adjusting belt 50 passes through the adjusting hole 11 and bypasses the adjusting member 30, and then passes through the adjusting hole 11. The end of the adjusting member 30 is movably connected to the peripheral wall of the adjusting hole 11 corresponding to the end, and one side of the adjusting member 30 is elastically connected to the peripheral wall of the adjusting hole 11 corresponding to the side. An elastic component can be provided on one side of the adjusting member 30 to connect the peripheral wall of the adjusting hole 11, or an elastic component can be provided on the peripheral wall of the adjusting hole 11 to connect the side of the adjusting member 30, so that the adjusting member 30 can be elastically abutted against the peripheral wall of the adjusting hole 11. The connecting section 53 is located on the side of the elastic connection of the adjusting member 30, and the adjusting section 51 is located on the other side of the adjusting member 30. The arrangement of this structure enables the elastic component to press against the adjusting member 30 in a natural state, so that the adjusting member 30 is squeezed by the elastic force and fixes the adjusting section 51 of the adjusting belt 50, preventing the adjusted connecting section 53 from loosening. At this time, the length of the adjusting section 51 and the connecting section 53 is not changed by external pulling, effectively ensuring the firmness of the fixing belt adjustment device 100. At the same time, when it is necessary to adjust the length of the adjusting belt 50, the adjusting member 30 is manually pressed to resist the elastic force of the elastic connection, so that the adjusting member 30 moves in the direction of the elastic connection, thereby loosening the adjusting section 51 and causing the connecting section 53 to lengthen or shorten.

[0038] The fixing belt adjustment device 100 of the technical solution of the present invention comprises a buckle body 10, an adjustment member 30 and an adjustment belt 50. After the size is adjusted, the adjustment member 30 squeezes the adjustment section 51, thereby enabling the fixing belt adjustment device 100 to be firmly locked. At the same time, the adjustment member 30 is manually pressed so that the adjustment member 30 moves toward the peripheral wall of the adjustment hole 11 against the elastic force, thereby smoothly loosening the adjustment section 51 for easy adjustment. The fixing belt adjustment device 100 has a simple fixing structure and has no restrictions on the material of the adjustment belt 50, so it has a wide range of applications.

[0039] Please refer to Figure 2 and Figure 3 In an optional embodiment, at least one elastic member 70 is provided on the peripheral wall of the adjustment hole 11 , and the adjustment member 30 is provided with a docking portion 31 , and the docking portion 31 is fixedly connected to the elastic member 70 .

[0040] In this embodiment, the peripheral wall of the setting adjustment hole 11 is connected with an elastic member 70, and a docking portion 31 is provided on one side of the adjustment member 30, and the docking portion 31 is fixedly connected to the elastic member 70. Such a structure can appropriately reduce the length of the elastic member 70, and can ensure that the elastic member 70 is not easy to deviate in the direction of the adjustment member 30, thereby improving the resistance force. Of course, the length of the elastic member 70 and the docking portion 31 can be set according to the size of the fixed belt adjustment device 100, and while ensuring the strength of the elastic member 70, shaking can also be avoided, thereby improving the structural stability. Specifically, the elastic member 70 can be elastic according to its own structure, such as a spring, a leaf spring or a bellows, etc.; or other substances with elastic force due to their own material characteristics, such as silicone, etc., which are not limited here.

[0041] Please combine Figure 1 In an optional embodiment, two elastic members 70 are provided, and the adjusting member 30 is provided with two corresponding docking portions 31 .

[0042] In this embodiment, two elastic members 70 are provided, and two docking portions 31 are also provided on the adjusting member 30. Through the two elastic connection structures, the elastic force on the adjusting member 30 can be more obvious and stable, and the pressure of squeezing the adjusting section 51 is greater, further improving the firmness and stability of the fixing belt adjustment device 100. Of course, the number of elastic members 70 can also be increased according to the size of the buckle body 10.

[0043] In an optional embodiment, the two docking portions 31 are respectively close to two ends of the adjusting member 30 , and the distances between the two docking portions 31 and the middle portion of the adjusting member 30 in the length direction are equal.

[0044] In this embodiment, in order to improve the uniformity of the holding force of the elastic member 70 on the adjusting member 30, the distances between the two docking portions 31 and the middle of the adjusting member 30 are set to be equal, that is, the holding force of the two elastic members 70 on the adjusting member 30 is equal, so that the pressing of the adjusting member 30 on the adjusting belt 50 is more uniform, and the adjusting member 30 is also facilitated to move more smoothly. At the same time, the docking portions 31 are respectively close to the two ends of the adjusting member 30, so that the adjusting belt 50 can be wound around the middle position of the adjusting member 30, which can improve the firmness of the fixing belt and the comfort.

[0045] In an optional embodiment, the buckle body 10 is provided with a receiving hole 13 on the peripheral wall of the adjustment hole 11 , one end of the elastic member 70 is fixed in the receiving hole 13 , and the other end is connected to the docking portion 31 in the receiving hole 13 .

[0046] In this embodiment, the elastic member 70 is set as a spring. In order to further prevent the elastic member 70 from deflecting, a receiving hole 13 is opened on the peripheral wall of the adjustment hole. The receiving hole 13 is cylindrical. The diameter of the receiving hole 13 is adapted to the diameter of the elastic member 70, so as to ensure smooth compression and recovery of the elastic member 70, and prevent radial swing, thereby improving the stability of the elastic force of the elastic member 70 along its axial direction. At the same time, the elastic member 70 is connected to the docking portion 31 in the receiving hole 13, which can further ensure the stability of the resisting force of the elastic member 70 and improve the stability and firmness of the extrusion adjustment section 51 of the adjustment member 30. One end of the elastic member 70 is fixed in the receiving hole 13, and the other end is connected to the docking portion 31, which can be connected by welding or the like.

[0047] Of course, in other embodiments, the elastic member 70 may also be directly connected to the peripheral wall of the adjustment hole 11 .

[0048] In an optional embodiment, the docking portion 31 is rod-shaped, and a center line of the docking portion 31 is perpendicular to a center line of the adjusting member 30 .

[0049] In this embodiment, the docking portion 31 is rod-shaped, which can be well matched with the spring of the cylinder to improve the connection stability. At the same time, the adjusting member 30 is also rod-shaped, so that the friction between the adjusting belt 50 and the adjusting member 30 is small, and the length of the connecting section 53 can be easily adjusted to save effort. The center line of the docking portion 31 is set perpendicular to the center line of the adjusting member 30, so that the holding force of the elastic member 70 is fully applied to the extrusion fixing direction of the adjusting member 30, and the elastic force of the elastic member 70 is maximized. Of course, in other embodiments, when the shape of the adjusting hole 11 is circular, the center line of the docking portion 31 and the center line of the adjusting member 30 can also be set at an acute angle.

[0050] Please refer to Figure 2 In an optional embodiment, one of the end of the adjusting member 30 and the peripheral wall of the adjusting hole 11 corresponding to the end is provided with a sliding groove 33, and the other is formed with a guide rail 15, and the guide rail 15 slides in cooperation with the sliding groove 33.

[0051] In this embodiment, the end of the adjusting member 30 and the peripheral wall of the corresponding adjusting hole 11 are provided with a sliding fit connection, which reduces the friction between the adjusting member 30 and the buckle body 10, and can further improve the smoothness of the movement of the adjusting member 30. Therefore, when the size needs to be adjusted, manpower can be saved; when it is adjusted to a suitable position, it can be quickly fixed, saving time and effort and not prone to loosening. Of course, in other embodiments, the end of the adjusting member 30 can also be provided with a ring sleeved on the peripheral wall of the adjusting hole 11, so that a movable connection can also be achieved. In addition, one end can be a sliding connection and the other end can be a sleeve connection.

[0052] In an optional embodiment, the two opposite walls of the adjustment hole 11 are configured as the guide rails 15 , and the sliding grooves 33 are formed at both ends of the adjustment member 30 .

[0053] In this embodiment, both ends of the adjusting member 30 are slidably connected to the two walls of the adjusting hole 11, which effectively improves the smoothness of movement of the adjusting member 30. Specifically, because the buckle body 10 is plate-shaped, the surrounding wall of the adjusting hole 11 is also plate-shaped, and the adjusting member 30 is rod-shaped, the sliding grooves 33 opened at both ends thereof are U-shaped grooves, which match the surrounding wall of the adjusting hole 11, have a simple structure, are easy to process, and the sliding connection structure is stable and will not fall off. Of course, in other embodiments, the sliding groove 33 can also be set on the surrounding wall of the adjusting hole 11, and the sliding groove 33 is a rectangular parallelepiped. The end of the adjusting member 30 does not need to be processed and is the guide rail 15, which can slide when inserted into the sliding groove 33.

[0054] Please continue to refer to Figure 1 In an optional embodiment, the adjustment hole 11 is located at one end of the buckle body 10 , and a mounting portion 17 is further provided at one end of the buckle body 10 away from the adjustment hole 11 .

[0055] In this embodiment, the fixing strap adjustment device 100 is used on various devices. Therefore, in addition to having an adjustable adjustment strap 50, it should also have a mounting portion 17 that is connected to various devices. The mounting portion 17 is connected to the mounting portion 17 on one side of the device, and the connecting section 53 is connected to the other side of the device, so that the function of wearing or wearing can be realized.
