A few preferred embodiments are described in conjunction with the accompanying drawings, and the structural features of the present invention and their functions are as follows, so that they are easy to understand and identify.

First of all, please refer to the first to sixth figures at the same time. The creation system includes: a bracket 1 having an arc-shaped shape, and a plurality of female fasteners 11 at the inner end to buckle with the male buckle of the front end of the cap 10 The inner side of the bracket 1 has a recess 12, the recess 12 has a central hole 13 and a through hole 14, the outer side of the bracket 1 has a tenon 15 and a protrusion 16; A waterproof strip 2 is disposed on the inner side of the inner side of the bracket 1 and is made of plastic (rubber) rubber or EVA foam material which is impervious to water and has elasticity and elasticity, such as rubber, TPR, SBR, EVA, etc. The end is fixed to the upper end of the inner side of the bracket 1 by a strong adhesive, and is located above the female fastener 11 and the other end can be closely attached to the surface of the shell 10. Please refer to the sixth figure at the same time; 3, disposed at the outer ends of the bracket 1, comprising a swaying piece 3a and a pedestal 3b, wherein the swaying piece 3a is annular, each end has a protruding rod 31 for inserting the bracket through hole 14, the swaying piece 3a is formed in a fixed state, the end surface of the swaying piece 3a has a plurality of undulating convex teeth 32; the pedestal 3b has a circular concave shape, and is attached to the bracket ridge 15 , the inside of the inside can accommodate the swaying piece 3a at the same time, the inner wall of the wall has a plurality of undulating disk teeth 33 to engage with the protruding teeth 32 of the swaying piece, the outer side of the pedestal 3b The end cap has a protruding rod 34; however, the cap adjusting device 3 is substantially identical to the new type M475839 patent, which is a conventional technique and will not be described again; and a lens 4 is arc-shaped and presents The top and bottom are tapered from the outside to the inside, so that the curvature of the lens 4 is formed to be wide and narrow, please refer to the fourth figure. The two ends of the lens have a central hole 41, two recessed holes 42 and a protrusion 43 for inserting the base protrusion 34. The outer ends of the lens 4 are opposite to the bracket recess 12 There is a fish eye hole 44 (located above the center hole 41) to pivotally connect with the bracket 1 by a fixing member 45 (for example, a rivet, a screw, etc.), and position the cover adjusting device 3 on the bracket 1 and the lens 4 At this time, the head of the fixing member 45 is immersed in the lens fish eye 44, and the tail end side is not embedded in the bracket recess 12, as shown in the fifth figure, and the lens 4 and the lens 4 can be completely avoided. The cap 10 contacts or rubs.

According to the above configuration, the bracket 1 is fastened to the cap 10, so that the lens 4 is mounted and positioned at the front end of the cap 10, and is in a closed state, as shown in the first figure. When the lens 4 is to be lifted, as long as the hand presses the lens 4 to push up, and the fixing member 45 is used as the rotating axis, the lens 4 is used to synchronously drive the base 3b. In order to change the position of the teeth 33 and the teeth 32, the lens 4 can be disengaged, as shown in the seventh figure, when the convex body 43 of the lens is stopped by the bracket protrusion 16, so that The lens 4 cannot be moved up.

On the contrary, as long as the lens 4 is pulled down again, the base 3b is rotated synchronously, and the position of the teeth 33 and the teeth 32 is changed, so that the lens 4 can be closed and restored, as shown in the first figure.

In other words, the present invention pushes and pulls the lens 4 up and down, and changes the engaging and pulling of the protruding teeth 32 and the disk teeth 33 via the cover adjusting device 3, and the lens 4 is opened or closed, such as the first and seventh figures. As shown in the figure, at the same time, when the lens 4 is opened, it is easily affected by the wind or the external force, so that the protrusion 43 and the stop 16 are used to achieve the more accurate positioning.

Therefore, as can be seen from the above description, this creation has at least the following advantages and effects, and is far more advanced than the conventional ones.

1. There is a feature of the new type M475839, that is, the cover adjusting device, between the swaying piece 3a and the base 3b, having teeth (protruding teeth 32 and disk teeth 33) that are laterally and laterally engaged with each other. Therefore, the operation can be labor-saving and low noise, and even no noise.

2. When the lens 4 is opened, it is not affected by the wind or the external force, and the effect of the positioning of the lens on the lens 4 can be ensured.

3. The ends of the fixing member 45 are respectively immersed in the lens fisheye 44 and the bracket recess 12, please refer to the fifth figure at the same time, so when the lens 4 is pushed up and down to drive the fixing member 45 to rotate, it will not be with the cap. The shell 10 and the lens 4 generate friction, and scratch damage to the cap 10 and the lens 4 can be avoided.

4. The inner side of the inner side of the bracket 1 is provided with a waterproof strip 2, as shown in the sixth figure, and located above the female snap fastener 11, not only can form a close fit with the surface of the cap shell 10, but also the bracket 1 and the cap shell. The gap between 10 is filled and closed, so when it rains, the rain that flows down from the cap 10 Water, the top surface of the waterproof strip 2 is discharged from both sides, so that the wearer of the helmet can not be affected by the rain and affect the driving sight, and the metal buckle can be protected from rust.

5. The lens 4 of the present invention is arc-shaped, please refer to the fourth figure at the same time, not only from the top to the bottom, but also from the outside to the inside, so that the curvature of the lens 4 is formed in a wide and narrow state, so Increase the shielding effect of the lens 4.

Referring to FIG. 8 again, the bracket in the present invention can be in the state of the inner and outer double brackets 1a and 1b, that is, the inner bracket 1a has the female fastener 11 and is fastened to the cap and fixed. The adjusting device 3 is disposed between the inner and outer brackets 1a, 1b, and the lens 4 is disposed outside the outer bracket 1b. The outer bracket 1b can be displaced up and down in synchronization with the lens 4 to achieve the first embodiment. The same effect, this is the second embodiment of the present creation.

Referring to the ninth figure, the bracket system in the present invention may include a bracket 1c and a visor 5, the bracket 1c is located on the outer side and combined with the lens 4, and the visor 5 is located on the inner side and has a female fastener. In order to be fastened to the cap, the bracket 1c can be displaced up and down in synchronization with the lens 4 to achieve the same effect as the first embodiment described above, which is the third embodiment of the present invention.

Referring to the tenth figure, the bracket in the present invention can be a visor 5, which is fastened to the cap and fixed to the lens 4, so that the lens 4 can be adjusted by the upper and lower displacement cover. Positioning to achieve the same effect as the first embodiment described above, which is the fourth embodiment of the present creation.

However, the above-mentioned ones are intended to illustrate the specific features and effects of this creation, and are not intended to limit the scope of the patents of this creation, especially the part of the cover adjustment device, which is equivalent to the structural changes made by the technical idea of the creation. It is still considered to be included in the scope of the patent of this creation.

To sum up, the specific structure disclosed in this creative embodiment is found to be unsatisfied by the practitioners and can achieve the intended purpose and effect. It can be called a novel and progressive creation, and a new type of patent is proposed according to law. Application.
