DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1: Please refer to Figures 1 to 4 A semi-automatic closing lens base for a helmet comprises two lens holders 1, one side surface of the two lens holders 1 is connected with a rotatable folding mirror 2, one side surface of the folding mirror 2 is fixedly connected with two lens clamping feet 4, the lens clamping feet 4 are respectively connected to one side surface of the two lens holders 1 through two rotating shafts 5, one side surface of the lens holder 1 is also provided with a slider 3 engaged with the folding mirror 2, the folding mirror 2 can be slid open and closed according to the slider 3, a locking mechanism is provided inside the lens holder 1, and one side surface of the lens holder 1 is also provided with a fixing component for fixing the position of the folding mirror 2;

[0022] The positioning mechanism includes: a movable card block 6, a slideway is provided inside the lens holder 1 to facilitate the movement of the movable card block 6, and the upper and lower surfaces of the slideway are fixedly installed with limit bars 7 for enhancing the stability of the movable card block 6 when sliding, and the upper and lower surfaces of the movable card block 6 are provided with limit grooves that match the limit bars 7, and a limit card plate 13 is fixedly installed on one side surface of the limit bar 7, and a limit plug 15 that matches the limit card plate 13 is fixedly connected to one side surface of the rotating shaft 5. The positioning mechanism also includes: a sliding card block 8, and a sliding groove 9 is provided inside the lens holder 1 to facilitate the movement of the sliding card block 8 A shaft 10 is provided at the center of the sliding block 8, and the sliding block 8 can rotate slightly according to the shaft 10. A connecting port is provided at the center of the sliding block 8, and a connecting seat 11 is fixedly installed inside the connecting port. The upper surface of the connecting seat 11 and one side of the movable block 6 are connected to the inner side surface of the lens holder 1 through a connecting spring 12. A limiting tooth 14 is fixedly installed on the upper surface of the sliding block 8, and the limiting tooth 14 cooperates with the limiting plug 15. A plurality of mounting seats 16 are also provided on the side surface of the lens holder 1, and the equipment is spliced ​​by the mounting seats 16 cooperating with screws;

[0023] The fixing assembly includes: a hidden groove 18, which is fixedly installed on one side surface of the lens holder 1. The interior of the hidden groove 18 is connected to a rotatable fixed card plate 19 through a rotating rod, and a fixed clamping ring 17 that matches the fixed card plate 19 is fixedly installed on one side surface of the rotating shaft 5.

[0024] In this embodiment, the folding mirror 2 is connected to the lens holder 1 through the lens clamping foot 4 and the rotating shaft 5, allowing the folding mirror 2 to rotate around the rotating shaft 5, thereby realizing the opening and closing operation. The slider 3 is engaged with the folding mirror 2.

[0026] When the folding mirror 2 needs to be fixed at a certain position, the fixing assembly will play a locking role. The fixing clamping plate 19 in the hidden groove 18 is connected by a rotating rod and can be rotated around the rotating rod. When the folding mirror 2 reaches the desired position, the fixing clamping ring 17 will cooperate with the fixing clamping plate 19. By rotating the fixing clamping plate 19, it is clamped with the fixing clamping ring 17, thereby fixing the position of the folding mirror 2;

[0027] The side surface of the lens holder 1 is provided with a plurality of mounting seats 16. Through the cooperation of these mounting seats and screws, the entire base can be conveniently mounted on the helmet, or disassembled and replaced as required.
