[0024] The present application provides a helmet eyepiece fixing buckle that is easy to disassemble, comprising a base and a magnetic suction cup matched with the base, wherein the inside of the magnetic suction cup and the inside of the base are respectively provided with magnetic parts that can make the magnetic suction cup and the base magnetically attracted to each other, and the magnetic attraction with the base can be released by rotating the magnetic suction cup; a movable clamping part for clamping and fixing the magnetic suction cup is provided on the base, and a clamping portion that clamps with the clamping part is provided on the magnetic suction cup, and the clamping part can be separated from the clamping portion by rotating the magnetic suction cup.

[0025] Implementation example Figures 1 to 3 As shown, a helmet eyepiece fixing buckle that is easy to disassemble includes a base 1 and a magnetic suction cup 2 that cooperates with the base 1. The base 1 is respectively arranged on both sides of the helmet, and the magnetic suction cup 2 is respectively arranged on both sides of the eyepiece. The base 1 and the magnetic suction cup 2 are detachably connected, so that the eyepiece can be detachably arranged on the helmet.

[0026] Specifically, the magnetic chuck 2 is provided with a disc-shaped connecting portion 2.1 protruding toward the base 1, and the base 1 is provided with a connecting groove 1.1 that matches the connecting portion 2.1. The connecting portion 2.1 can be at least partially inserted and accommodated in the connecting groove 1.1, and the magnetic chuck 2 and the base 1 are relatively rotated with the connecting portion 2.1 as the axis. A magnetic member 3 (a magnet in this embodiment) is arranged inside the magnetic chuck 2 at the position of the connecting portion 2.1, and a magnetic member 3 is also arranged inside the base 1 at the position of the connecting groove 1.1. The magnetic poles of the magnetic member 3 in the base 1 and the magnetic member 3 in the magnetic chuck 2 are arranged in opposite directions, so that the base 1 and the magnetic chuck 2 are magnetically attracted to each other, and when the magnetic chuck 2 and the base 1 rotate relative to each other, the magnetic attraction between the magnetic chuck 2 and the base 1 can be released.

[0027] Furthermore, a magnetic guide shielding plate 4 is provided on the side of the magnetic component 3 in the magnetic suction cup 2 away from the base 1, and a magnetic guide shielding plate 4 is provided on the side of the magnetic component 3 in the base 1 away from the magnetic suction cup 2, which effectively prevents the magnetic component 3 from affecting other objects.

[0028] Furthermore, at least two movable clamping parts 5 are equidistantly distributed on the inner wall of the connection groove 1.1 along the circumferential direction. In this embodiment, two clamping parts 5 are arranged oppositely on both sides of the connection part 2.1 of the magnetic suction cup 2. A clamping part 2.2 is convexly provided on the connection part 2.1 of the magnetic suction cup 2 along the circumferential direction to engage with the clamping part 5. When the clamping part 5 engages with the clamping part 2.2, the magnetic suction cup 2 is axially fixed on the base 1 and cannot be separated, but can rotate relative to the base 1.

[0029] Furthermore, the clamping portion 2.2 is provided with a disengagement slot 2.3 whose opening is not smaller than the clamping element 5. The magnetic chuck 2 is rotated to make the disengagement slot 2.3 correspond to the position of the clamping element 5, so that the clamping element 5 can be disengaged from the clamping portion 2.2 through the disengagement slot 2.3.

[0030] Furthermore, the clamping member 5 and / or the clamping portion 2.2 are provided with an inclined surface for facilitating the clamping member 5 to be clamped into the clamping portion 2.2.

[0031] Furthermore, the base 1 is provided with a receiving cavity for accommodating the clip 5, the clip 5 can be telescopically movable in the receiving cavity and an elastic member 6 (a spring in the embodiment of the present application) is provided between the clip 5 and the receiving cavity, the elastic member 6 makes the clip 5 have a tendency to reset after movement.

[0032] Working principle: When in use, the connecting part 2.1 of the magnetic suction cup 2 can be directly pressed into the connecting groove 1.1 of the base 1. The clamping part 5 is retracted into the accommodating cavity under the pressure, and pops out and clamps with the clamping part 2.2 under the action of the elastic part 6. At this time, the magnetic suction cup 2 and the base 1 are relatively fixed in the axial direction.

[0033] When unlocking, the magnetic chuck 2 is rotated relative to the base 1, and the disengagement slot 2.3 is rotated to the position of the clamping member 5, so that the magnetic chuck 2 and the base 1 can be disengaged from each other.

[0034] Those skilled in the art should understand that the technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
