Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0046] Embodiment 1

[0047] Referring to Figures 1-12 As shown in the figure, a baseball helmet comprises a shell 1, an adjustable device 2 and a ring cloth 3.

[0048] The shell 1 is provided with a cavity for covering the head, and the cavity is provided with an opening 11 for accommodating the head. An inner liner (not shown) is fixed in the shell, and the inner liner is provided with a first rubber layer and a first sponge layer. The function of the inner liner is to have a buffering effect on one hand, and to increase the comfort of the helmet on the other hand.

[0049] The ring cloth 3 has one end fixed around the opening, and the inside of the ring cloth 3 is sequentially filled with a second rubber layer 31 and a second sponge layer 32. The ring cloth 3 is used to wrap and stick to a circle including the forehead, and the second sponge layer 32 is close to the forehead. The ring cloth 3 is in a hanging state in a free state without use and external force.

[0050] The adjustable device 2 comprises an adjusting wire 21 and a rotating wheel assembly, and the rotating wheel assembly is arranged on the upper shell. The adjusting wire 21 extends from the rotating wheel assembly and returns to the rotating wheel assembly around the second rubber layer in the ring cloth, so that the rotating wheel assembly rotates to drive the adjusting wire to stretch and contract, so as to adjust the tightness of the ring cloth on the forehead.

[0051] As a specific embodiment, the second rubber layer 31 is provided with an annular groove 33, and the adjusting wire 21 is located in the annular groove 33. In this way, the sliding wire can be avoided, and the position of the adjusting wire is limited in the annular groove.

[0052] As a specific embodiment, the ring cloth 3 is made of a high-molecular waterproof and breathable material PTFE film plus a breathable cloth. In this way, it can prevent sweat from penetrating into the ring cloth, and also has the function of air permeability.

[0053] As a further preferred embodiment, the second rubber layer 31 is provided with first air holes (not shown), and the second sponge layer 32 is provided with second air holes (not shown), the first air holes and the second air holes being in communication, so that the entire girdle cloth has the functions of preventing sweat from penetrating and being breathable.

[0054] Referring to Figures 4-12 As shown in the figure, the rotating wheel assembly comprises an outer wheel 22, a middle wheel 23 and an inner wheel 24. The middle of the outer wheel 22 is provided with a first protruding part 221, the first protruding part 221 is provided with a plurality of insertion slots 222 in the shape of a ray of light, and the first protruding part 221 and the outer wheel 22 are provided with a movable space 223. The middle wheel 23 is installed in the movable space 223, so that the middle wheel 24 can rotate and move up and down in the movable space 223. The middle wheel 23 and the outer wheel 22 are further fixed with elastic devices 231. The inner wheel 24 is installed in the middle wheel 23, and the inner wheel 24 and the middle wheel 23 can be fixed by buckling or bonding. The middle of the inner wheel 24 is provided with a second protruding part 241, the second protruding part 241 is provided with a plurality of insertion pins 242 in the shape of a ray of light, and the insertion pins 242 can be matched and inserted into the insertion slots 222. The adjusting line 21 is installed on the inner wheel 24, specifically, it is wound on the inner wheel 24.

[0055] The elastic devices 231 are springs 231, one end of the spring 231 is fixedly connected to the outer wheel 22, and the other end of the spring 231 is fixedly connected to the middle wheel 23. The middle wheel 23 can be provided with a plurality of spaced handles 232, which can be 2, 3 or 4. As an alternative embodiment, the middle wheel 23 is provided with 3 spaced handles 232. The outer circumferential side of the outer wheel has anti-slip stripes.

[0056] As an alternative, the first protruding part is provided with an insertion pin instead of an insertion slot, and the corresponding second protruding part is provided with an insertion slot instead of an insertion pin.

[0057] That is, the first protruding part can be provided with an insertion pin / insertion slot, and the corresponding second protruding part is provided with an insertion slot / insertion pin to cooperate with the first protruding part.

[0058] As an alternative embodiment, the number of insertion slots is 10-30, and the number of insertion pins is equal to the number of insertion slots. For example, when the number of insertion slots is 12, the number of insertion pins is also 12. When the number of insertion slots is 22, the number of insertion pins is also 22. The more the number, the higher the fine adjustment.

[0059] Taking a baseball helmet as an example, the adjustment process of the tightness of the girdle cloth is as follows:

[0060] One hand holds the outer periphery of the outer wheel 22, and the anti-slip stripes can play the role of anti-slip; the other hand has three fingers placed on the handles of the middle wheel 23. Since the movable space 223 is movable up and down (for exampleFigure 10 The upper and lower arrows are displayed (D-E), so that the middle wheel 23 can be pulled out in the active space 223. Since the middle wheel 23 and the inner wheel 24 are fixed, the inner wheel 24 is pulled out; after the inner wheel 24 is pulled out, the second protruding part 241 of the inner wheel 24 and the first protruding part 221 of the outer wheel 22 are separated, so that the inner wheel 24 can be rotated, and the adjustment of the elastic band is stretched, so that the tightness of the elastic band on the forehead is adjusted. When the adjustment is completed, the other hand is released, and under the action of the spring 231, the inner wheel 24 is elastically pulled back, and the pin 242 is reinserted into the slot 222.

[0061] Since the force during the adjustment process is bidirectional, it cannot be automatically adjusted unless manually adjusted, and has stability after adjustment.

[0062] By rotating the wheel assembly to stretch the adjustment rope, the tightness of the elastic band on the forehead is adjusted, so that the adjustability of the elastic band at the opening of the cavity and the firmness of the elastic band connected to the head are increased.

[0063] It should be noted that the elastic band is not in the shape of an O, but in the shape of a C. In addition, the terms "first", "second", etc. are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.
