[0055] As Figures 1-3 shown, the present utility model provides an adjustable glasses mask, which comprises a mask body 1, a connecting member 2 and a rotating assembly 3. The mask body 1 is used to abut against the user's face; the connecting member 2 is arranged on the inner side of the mask body 1, and the connecting member 2 is connected to the VR glasses 5. A plurality of buckles can be arranged on the connecting member 2, and clamping grooves are arranged at corresponding positions on the VR glasses 5. The connecting member 2 and the VR glasses 5 are detachably connected in a clamping manner through the cooperation of the buckles and the clamping grooves. The rotating assembly 3 is movably arranged on the mask body 1; a first tooth 31 is arranged on one end of the rotating assembly 3 facing the connecting member 2 along the circumferential direction, and a linear rack 21 meshing with the first tooth 31 is arranged on the connecting member 2. The linear rack 21 extends along the front-back direction of the connecting member 2. By rotating the rotating assembly 3, the connecting member 2 can be moved along the front-back direction to adjust the distance between the VR glasses 5 and the mask body 1. In the present application, the front-back direction is the direction relative to the human eyes when the present utility model is used. The direct viewing direction of the eyes is the front, and the opposite is the rear.

[0056] When the present utility model is used, since the first tooth 31 on the rotating assembly 3 meshes with the linear rack 21 on the connecting member 2, by rotating the rotating assembly 3, the linear rack 21 can drive the connecting member 2 to move, so as to realize the arbitrary adjustment of the distance between the VR glasses 5 and the mask body 1. The operation is simple and convenient, which is convenient for users with and without glasses, improves the comfort of users, and enables users to obtain a better experience.

[0057] Preferably, two groups of rotating assemblies 3 are arranged on the mask body 1, and the two groups of rotating assemblies 3 are respectively located on the left and right side surfaces of the mask body 1, and the corresponding linear racks 21 on the connecting member 2 are also arranged in two groups. This improves the relative movement stability between the connecting member 2 and the mask body 1.

[0058] In one embodiment, as Figures 3-8As shown in the figure, the rotating assembly 3 includes a rotating member 32 and an end cap 33. A hole groove 15 adapted to the rotating assembly 3 is provided on the mask body 1, such that the rotating member 32 is disposed in the gap between the mask body 1 and the connecting member 2, and the end cap 33 is disposed on the outer side of the mask body 1 facing away from the connecting member 2. The end cap 33 is connected to the rotating member 32; the first tooth 31 is disposed at one end of the rotating member 32 facing the connecting member 2.

[0059] In this embodiment, the rotating member 32 is located inside the mask body 1, and the end cap 33 is located outside the mask body 1. The rotating member 32 is connected to the end cap 33. During use, rotating the end cap 33 can drive the rotating member 32 to rotate, so that the linear rack 21 drives the connecting member 2 to move, thereby realizing the arbitrary adjustment of the distance between the VR glasses 5 and the mask body 1.

[0060] In one embodiment, the rotating assembly 3 further includes a spacer 34 disposed between the mask body 1 and the rotating member 32. A connecting post 321 is disposed on one side of the rotating member 32 facing the end cap 33. The spacer 34 is sleeved on the connecting post 321, and the spacer 34 is movable along the axial direction of the connecting post 321 between the spacer 34 and the rotating member 32; a spring 35 is further disposed between the spacer 34 and the rotating member 32, and the spring 35 is sleeved on the connecting post 321 of the connecting member 2. A plurality of first limiting protrusions 331 are disposed at intervals in the circumferential direction on one side of the end cap 33 facing the spacer 34, and a plurality of second limiting protrusions 341 are disposed at intervals in the circumferential direction on one side of the spacer 34 facing the end cap 33. The first limiting protrusion 331 can be engaged in the gap between two adjacent second limiting protrusions 341, and the second limiting protrusion 341 can be engaged in the gap between two adjacent first limiting protrusions 331. The first limiting protrusion 331 on the end cap 33 and the second limiting protrusion 341 on the spacer 34 cooperate with each other and are located in the hole groove 15 of the mask body 1; a through hole 332 is provided on the end cap 33, and a fixing member 36 connected to the connecting post 321 of the connecting member 2 is disposed in the through hole 332. The fixing member 36 can be a screw or a bolt.

[0061] In this embodiment, the setting of the spring 35 can make the spacer 34 always abut against the end cap 33. The first limiting protrusion 331 on the end cap 33 and the second limiting protrusion 341 on the spacer 34 cooperate with each other, so that while the end cap 33 and the spacer 34 are movably connected, they cannot rotate relative to each other. Therefore, when the end cap 33 is rotated, the spacer 34 can be driven to rotate at the same time. The spacer 34 and the rotating member 32 move along the axial direction of the connecting post 321. Therefore, by rotating the end cap 33, the spacer 34 and the rotating member 32 can be rotated simultaneously and synchronously, realizing the forward and backward movement of the connecting member 2, and improving the smoothness of rotation of the rotating assembly 3.

[0062] In one embodiment, a plurality of third limiting bumps 322 are arranged at intervals in the circumferential direction on one side of the rotating member 32 facing the isolating member 34, and a plurality of fourth limiting bumps 342 are arranged at intervals in the circumferential direction on one side of the isolating member 34 facing the rotating member 32. The third limiting bumps 322 can be caught in the gaps between two adjacent fourth limiting bumps 342, and the fourth limiting bumps 342 can be caught in the gaps between two adjacent third limiting bumps 322.

[0063] In this embodiment, the third limiting bumps 322 on the rotating member 32 and the fourth limiting bumps 342 on the isolating member 34 cooperate with each other to prevent the rotating member 32 and the isolating member 34 from rotating relative to each other, so that they can only move axially along the axis of the rotating member 32.

[0064] In one embodiment, a limiting groove 343 extending along the axial direction of the connecting column 321 is provided on either the outer surface of the connecting column 321 of the rotating member 32 or the inner surface of the isolating member 34, and a limiting post 323 adapted to the limiting groove 343 is provided on the other. The positioning and mating installation of the rotating member 32 and the isolating member 34 is realized, so that the rotating member 32 and the isolating member 34 can move axially but cannot rotate axially.

[0065] The first embodiment of the connection between the connecting column 321 and the limiting groove 343 is as Figure 4 shown. A limiting post 323 is provided on the outer surface of the connecting column 321 of the rotating member 32. As Figure 6 shown, a limiting groove 343 is provided on the inner surface of the isolating member 34. The positioning and mating installation of the rotating member 32 and the isolating member 34 is realized through the cooperation between the limiting post 323 on the rotating member 32 and the limiting groove 343 on the inner surface of the isolating member 34.

[0066] The second embodiment of the connection between the connecting column 321 and the limiting groove 343 is as Figure 5 shown. A limiting groove 343 is provided on the outer surface of the connecting column 321 of the rotating member 32, and a limiting post 323 (not shown in the figure) is provided on the inner surface of the isolating member 34.

[0067] Furthermore, the width of the first limiting bump 331 gradually increases from the end away from the end cover 33 to the end close to the end cover 33, and the width of the second limiting bump 341 gradually increases from the end away from the isolating member 34 to the end close to the isolating member 34, which is convenient for the connection between the end cover 33 and the isolating member 34.

[0068] Further, the limiting column 323 is disposed on the outer surface of the connecting column 321 of the rotating member 32, and the limiting groove 343 is disposed on the inner surface of the fourth limiting projection 342 of the isolating member 34.

[0069] Further, the width of the third limiting projection 322 gradually increases from the end away from the rotating member 32 to the end close to the rotating member 32, and the width of the fourth limiting projection 342 gradually increases from the end away from the isolating member 34 to the end close to the isolating member 34, facilitating the connection between the connecting member 22 and the isolating member 34.
