[0035] Reference Figure 1 A fitness belt according to an embodiment of the present invention includes a belt body 100. Adjustment mechanisms 110 and connecting blocks 102 are respectively provided at both ends of the belt body 100. The adjustment mechanism 110 includes a mounting base 111, a traction belt 115, a tightening assembly 120, a cover plate 112, and a limiting piece 113. The mounting base 111 is connected to the end of the belt body 100. The tightening assembly 120 has a winding shaft 121, which is pivotally connected to the mounting base 111. One end of the traction belt 115 is connected to the winding shaft 121. Meanwhile, the other end of the traction belt 115 has a buckle 116, which can be fastened to the connecting block 102, thus connecting the two ends of the belt body 100 via the traction belt 115.

[0036] Reference Figure 4 Furthermore, the connecting block 102 has a snap-fit ​​groove 103 surrounding the outer periphery of the connecting block 102. The snap-fit ​​ring 116 is wrapped around the outer periphery of the connecting block 102 and embedded in the snap-fit ​​groove 103, which can improve the snap-fit ​​stability between the snap-fit ​​ring 116 and the connecting block 102. Furthermore, a magnet block 104 is provided inside the connecting block 102. The snap-fit ​​ring 116 is made of iron, so the magnet block 104 can attract the snap-fit ​​ring 116, which can realize the quick snap-fit ​​between the snap-fit ​​ring 116 and the connecting block 102 and reduce the probability of the snap-fit ​​ring 116 coming off the connecting block 102, which is beneficial to improving the reliability of the connection.

[0037] Reference Figure 2 It is understood that the tightening assembly 120 is equipped with a handle 125 and a ratchet 123, and both ends of the take-up shaft 121 are equipped with ratchet 123, with the handle 125 connected to both ends of the take-up shaft 121. (Refer to...) Figure 6 Pulling the handle 125 can drive the take-up shaft 121 to rotate clockwise, thereby driving the ratchet 123 to rotate clockwise, thus winding up the traction belt 115, so that the traction belt 115 is wound around the outer circumference of the take-up shaft 121, achieving tightening adjustment.

[0038] It is understood that the ratchet 123 has multiple teeth 124 on its outer periphery. The limiting piece 113 is movably engaged with the ratchet 123 and inserted into the recess between two adjacent teeth 124, thereby restricting the ratchet 123 from moving back in the counterclockwise direction and preventing loosening.

[0039] Understandably, the limiting plate 113 is movably connected to the mounting base 111. When the limiting plate 113 disengages from the ratchet 123, the ratchet 123 can rotate counterclockwise, thereby releasing the traction belt 115 and facilitating the user to remove the belt body 100. Furthermore, the mounting base 111 is equipped with a third return spring 130, which is used to keep the limiting plate in contact with the ratchet 123. Simultaneously, the mounting base 111 has second guide grooves 129 on both sides, allowing the limiting plate 113 to move along the second guide grooves 129.

[0040] Reference Figure 3 It is understood that the handle 125 is provided with a drive plate 122, a first guide groove 128, and a second return spring 127. Specifically, the first guide groove 128 is provided on both sides of the handle 125, the drive plate 122 is movably inserted into the first guide groove 128, and the second return spring 127 elastically abuts against the drive plate 122 and keeps the drive plate 122 in contact with the ratchet 123, thereby realizing that the drive plate 122 is stably inserted into the recess between two adjacent teeth 124, so that the ratchet 123 can be driven to rotate when the handle 125 is pulled. Understandably, because the teeth 124 of the ratchet 123 are inclined, when the handle 125 rotates clockwise around the take-up shaft 121, it can drive the ratchet 123 to rotate through the drive plate 122; and when the handle 125 moves back in the counterclockwise direction, the drive plate 122 can rotate counterclockwise relative to the ratchet 123 to reset the handle 125, thereby ensuring that the handle 125 can continue to rotate clockwise to tighten the traction belt 115.

[0041] Furthermore, the cover plate 112 is pivotally connected to the mounting base 111 and can cover the handle 125 of the tightening assembly 120. The cover plate 112 has covering portions 117 on both sides, extending from the cover plate 112 towards the belt body 100. Each covering portion 117 has a limiting groove 114 with an opening. When the cover plate 112 covers the tightening assembly 120, both the drive plate 122 and the limiting plate 113 are located within the limiting groove 114. The side walls of the limiting groove 114 can restrict the movement of the drive plate 122 and the limiting plate 113. This prevents accidental contact with the limiting plate 113 during use, thus preventing the ratchet 123 from retracting and disengaging from the ratchet 123, and preventing the ratchet 123 from rotating and loosening. This helps ensure the safety and reliability of the usage process.

[0042] Reference Figure 5 It is understood that the winding shaft 121 is provided with a first return spring 126 around its outer circumference. One end of the first return spring 126 is connected to the cover plate 112 and the other end is connected to the mounting shaft. The first return spring 126 can realize the return of the cover plate 112 and keep the cover plate 112 covering the handle 125.

[0043] Reference Figure 6 Understandably, during the tightening operation, both the handle 125 and the cover plate 112 need to be pulled simultaneously to rotate clockwise, thereby allowing the ratchet 123 to rotate clockwise. Under the restraint of the limiting plate 113, the ratchet 123 cannot rotate counterclockwise, thus achieving the tightening of the traction belt 115.

[0044] Reference Figure 7 Understandably, during the release operation, rotating the cover plate 112 clockwise causes the drive plate 122 and the limiting plate 113 to disengage from the limiting groove 114. This allows the ratchet 123 to be released by manually pulling the drive plate 122 and the limiting plate 113, thus releasing the traction belt 115. Furthermore, the retaining ring 116 can disengage from the connecting block 102.

[0045] Reference Figure 1 The belt 100 is provided with at least two auxiliary rings 101, which can be used to connect other fitness equipment to enable more types of training to be carried out through the belt 100, thereby improving the flexibility of use.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
