[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0024] See also Figure 1-Figure 8 , as shown in the figure, is a hallux valgus corrector that can be quickly assembled. The corrector includes a sole fixing part fixed at the sole position and a toe fixing part fixed on the toes. The sole fixing part includes a sole fixing frame 4, a sole fixing belt 2 and a rear-drag fixing belt 3; the toe fixing part includes a big toe connecting frame and a big toe fixing belt 1. It also includes a fixing assembly universally connected to the end of the toe fixing part, that is, the end of the big toe connecting frame is designed as a ball head structure, and the ball head structure can make the toe fixing frame 7 and the entire fixing assembly universally rotate. The fixing assembly is fixed to one end of the sole fixing part, that is, the fixing assembly is fixed to one end of the sole fixing frame 4 as a whole, and an adjustment wheel 6 is movably sleeved on one end of the sole fixing frame 4 or the fixing assembly. The adjustment wheel 6 is a hollow annular structure, and the adjustment wheel 6 is provided with a protrusion 61 with different height differences toward one side of the fixing assembly. The corresponding toe fixing frame 7 is provided with a positioning groove 71 for the protrusion end to be inserted, and the toe fixing part is adjusted by the protrusions of different heights pushing up the toe fixing part. In this embodiment, in order to facilitate assembly production, the fixing assembly is plugged and buckled with the sole fixing part. Since the adjusting wheel 6 is freely rotatable, although there are protrusions 61 and positioning grooves 71 between the adjusting wheel 6 and the toe fixing frame 7 for limiting, this is only a limit in one direction, and the user's toes can still rotate freely in the up and down directions when wearing the device.
[0025] In order to further improve the production and assembly efficiency of the product, the fixing assembly is designed to include a fastener 5 and an upper cover 8 in this embodiment, wherein the fastener 5 is inserted and buckled with the sole fixing part, and the inner surface between the fastener 5 and the upper cover 8 forms a ball socket 9 for the ball head to be inserted and movable, and the upper cover 8 is buckled with the fastener. The lower end of the upper cover 8 is integrally provided with a first buckle 81, and the corresponding fastener 5 is provided with a socket 51 for the first buckle 81 of the upper cover 8 to be inserted and buckled. The lower end of the fastener 5 is integrally provided with a second buckle 52, and the corresponding sole fixing part is provided with a slot 41 for the second buckle 52 to be inserted and buckled. The various parts of the utility model adopt a socket or buckle connection method, and the entire product does not have a single screw, does not require any installation tools, and the parts are made of injection molding, with low production costs and extremely high assembly efficiency.
[0026] In order to enable the toe fixing frame 7 to rotate and adjust freely within a wide range, in this embodiment, the front end of the fastener 5 and the upper cover 8 for the toe fixing part to be inserted is provided with a recess 10 for the toe fixing part to move. The recess 10 can increase the wide range of movement of the toe fixing frame 7.
[0027] The lower end of the adjusting wheel 6 abuts against the sole fixing part. In order to prevent the adjusting wheel 6 from axial displacement, a limiting mechanism for limiting the axial displacement of the adjusting wheel 6 is provided between the adjusting wheel 6 and the fixing assembly in this embodiment. The limiting mechanism includes an inner ring convex 62 provided on the inner ring of the adjusting wheel 6, and the outer ring convex 53 protruding outward is provided on the corresponding outer ring of the fastener 5. After the fastener 5 is installed, the outer ring convex of the fastener 5 presses on the inner ring convex of the adjusting wheel 6 to form a limiting mechanism for limiting the axial displacement of the adjusting wheel 6. In order to facilitate the rotation of the adjusting wheel 6, an anti-slip convex pattern is provided on the circumferential outer surface of the adjusting wheel 6 in this embodiment.
[0028] In this embodiment, the toe fixing frame 7, the sole fixing frame 4, the adjusting wheel 6, the buckle and the upper cover 8 are all made of plastic injection molding.
