[0023] like Figure 1-7As shown, the goggle fixing and rotating structure of this utility model includes a lens holder 1, an intermediate connector 2, and an outer cover plate 3 for mounting on the helmet body. The lens holder 1 has a connector cavity 101 whose shape is adapted to the intermediate connector 2. The intermediate connector 2 is disposed in the connector cavity 101 and is radially slidable and circumferentially linked with the lens holder 1. The outer cover plate 3 is detachably connected to the intermediate connector 2. A goggle mounting space is provided between the lens holder 1 and the outer cover plate 3. The radially slidable arrangement of the intermediate connector 2 and the lens holder 1 can be achieved by a guide structure between the intermediate connector 2 and the connector cavity 101, which can be a guide between sliding planes or a fit between a groove and a protrusion. A wavy edge forming a stop part 102 is provided on one side of the lens holder 1 corresponding to the radial sliding direction. An elastic element 4 is provided between the lens holder 1 and the outer cover plate 3, and the elastic element 4 provides an elastic force between the lens holder 1 and the outer cover plate 3 along the radial sliding direction. A wavy edge forming a stop portion 102 is provided on one side of the lens holder 1 in the radial sliding direction. This is to cooperate with the positioning protrusion 501 provided on the goggles 5 to achieve multi-point positioning. The arc length of the stop portion 102 is related to the opening angle of the goggles 5, and the number of waves is related to the number of opening positions. The elastic force provided by the elastic member 4 is to maintain an elastic pressure between the stop portion 102 on the lens holder 1 and the positioning protrusion 501 on the goggles 5 at all times, so as to stabilize the position of the goggles 5.

[0024] The present invention will be further described below with reference to preferred embodiments. Specific Implementation

[0025] like Figure 1-7 As shown in this specific embodiment, the goggle fixing and rotating structure includes a lens holder 1, an intermediate connector 2, and an outer cover plate 3 for mounting on the helmet body; wherein, the intermediate connector 2 is an annular component with a rotating surface 201, and at least two grooves are evenly provided on the inner wall of the hole to form a snap-fit ​​groove 202. The rotating surface 201 is provided so that when the goggle fixing and rotating structure is installed on the goggle 5 through the mounting hole 502 on the goggle 5 and the rotating surface 201, the goggle 5 can rotate about the center of the rotating surface 201 to achieve opening or closing rotation. Figure 6 , 7As shown, the outer cover plate 3 is generally disc-shaped. A limiting plane 302, which mates with the end face of the intermediate connector 2, is provided on one side facing the intermediate connector 2. A latching foot 301 with a hook 303 mates with the latching groove 202 is also provided. In this specific embodiment, there are two latching grooves 202 and two corresponding latching feet 301. The radially outer surfaces of the two latching feet 301 are arc-shaped, adapting to the inner wall of the intermediate connector 2. The ends of the latching feet 301 have radial flanges forming the hooks 303. The latching feet 301 are inserted into the inner hole of the intermediate connector 2 and mate with the latching grooves 202 to form the detachable connection. In this specific embodiment, preferably, the intermediate connector 2 is a flat, generally concentrically stepped ring-shaped component with a smaller upper part and a larger lower part. The outer side of the upper ring forms a ring-shaped rotating surface 201. The connector cavity 101 on the lens holder 1 and the two opposite sides of the intermediate connector 2 are also provided with parallel sides forming a sliding guide plane 103. In this specific embodiment, the sliding guide plane 103 is disposed on the side of the lower annular ring, that is, each side of the lower annular ring has a parallel straight side surface forming the sliding guide plane 103; the shape of the connecting member cavity 101 is adapted to the lower contour of the intermediate connecting member 2, and a sliding space is provided in the sliding direction. The cavity depth is the same as the lower height of the intermediate connecting member 2. The intermediate connecting member 2 is disposed in the connecting member cavity 101. The annular end face of the upper annular ring abuts against the limiting plane 302. The gap between the front surface of the lens holder 1 and the limiting plane 302 forms the goggle installation space. That is, the height of the upper annular ring determines the goggle installation space. Figure 3 As shown. The lens mount 1 has several elongated slots 104 on both sides that are aligned with the sliding direction. In this specific embodiment, as shown... Figure 6 , 7 As shown, the elongated slot 104 is disposed on the two sidewalls of the connector cavity 101 on the side where the sliding guide plane 103 is provided. The sidewall of the elongated slot 104 is provided with an axial baffle 105. The axial baffle 105 restricts the relative axial movement between the lens holder 1 and the intermediate connector 2, preventing them from separating from each other.

[0026] In this specific embodiment, the elongated slot 104 is disposed on the side of the connector cavity 101. The front of the lens holder 1 is also provided with a notch that communicates with one end of the elongated slot 104. The shape of the notch matches the barb 203 to form the insertion port 106 of the barb 203. The side wall of the elongated slot 104 near the intermediate connector 2 forms the axial baffle 105. The intermediate connector 2 is provided with a barb 203 that matches the baffle 105 at a position corresponding to the elongated slot 104. The barb 203 is inserted into the elongated slot 104 and forms a barb with the baffle plane, and they slide radially together to prevent the intermediate connector 2 from disengaging. Thus, the lens holder 1 and the intermediate connector 2 are radially slidable and circumferentially linked. The back of the lens holder 1 is also provided with a spring cavity 107 that communicates with the elongated slot 104; the elastic element 4 is disposed in the spring cavity 107, and the elastic element 4 is preferably composed of a compression spring, with one end abutting against the barb 203 and the other end abutting against the side wall of the spring cavity 107.

[0027] In this specific embodiment, such as Figure 6 , 7 As shown, a plurality of guide elongated holes 108 aligned with the sliding direction can also be provided at the bottom of the connecting cavity 101 on the lens holder 1. A guide protrusion 204 is provided on the side of the intermediate connecting member 2 facing the lens holder 1 at a position corresponding to the guide elongated holes 108. The guide protrusion 204 is clearance-fitted into the guide elongated holes 108, such as... Figure 2 As shown.

[0028] like Figure 8-10 As shown, in application, the upper annular part of the intermediate connector 2 rotatably engages with the mounting hole on the goggles 5 from the inside. The locking feet 301 of the outer cover plate 3 pass through the mounting hole on the goggles 5 and the center of the upper annular part of the intermediate connector 2 from the outside. The barb 203 connects the two in the snap-fit ​​groove 202 on the inner wall of the intermediate connector 2. The connecting cavity 101 of the lens holder 1 engages with the intermediate connector 2. The barb 203 on the intermediate connector 2 is inserted into the insertion port 106 of the lens holder 1 into the elongated slot 104 and then slides to the other end to contact the baffle. The barb 203 and the baffle plane form a barb and slide radially together. Simultaneously, the guide protrusion 204 on the intermediate connector 2 is clearance-fitted into the guide elongated hole 108. Figure 2As shown, this constitutes a radially slidable and circumferentially linked connection between the lens holder 1 and the intermediate connecting member 2. Furthermore, the elastic member 4 is disposed in the spring cavity 107. The elastic member 4 is preferably composed of a compression spring, with one end abutting against the barb 203 and the other end abutting against the side wall of the spring cavity 107. This ensures that the barb 203 always has an elastic force that slides towards one end of the baffle, preventing the lens holder 1 and the intermediate connecting member 2 from detaching from each other, thus forming a goggle assembly.

[0029] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
