Description

Safety helmet lens cover positioning device

The present invention provides a safety cap lens cover positioning device, especially a structure that is simple in structure, easy to assemble, convenient to operate, noiseless, and accurate in positioning.

According to the conventional safety helmet lens, it is mainly installed at the front end of the cap for shading or windshield (sand). According to its structural design, the following two types are roughly distinguished:
(1) The lens is directly mounted on the cap; each side of the cap has an alcove to accommodate a base, and the inner side of the lens corresponds to the base and each has a structure capable of adjusting and positioning the cover, generally The tooth-to-tooth engagement mode is designed, and the lens and the base are locked on the outer shell by an ear cover on the outer side of the lens. However, this type has the disadvantages of many spare parts, complicated structure and time-consuming assembly.
(2) The lens system is fixed to the visor (or bracket), and then the visor (or bracket) is fastened to the hood; the tying tongue (or the bracket) has a base on both sides of the visor (or the bracket), and the pedestal The sleeve is provided with a flap, and the base and the flap are provided with intermeshing teeth, so that when the lens is operated, the flap can be rotated at the same time to change the meshing position to achieve splitting or For the purpose of covering the lens, the inner side of the visor (or bracket) and the front end of the hood have male and female fasteners, and the cymbals can be fastened to each other to mount the lens on the front end of the cap.
However, this type still has: 1. The cost of the mold for the visor (or bracket) is high, 2. There must be the cost of the flap parts and the mold opening, 3. There will be noise during operation, 4. The assembly is slightly troublesome, etc. Obviously there is room for improvement.

Therefore, the main creative purpose of this creation is to provide a helmet cap positioning device that is simple in construction and easy to assemble.
Another object of the present invention is to provide a hard hat lens cover positioning device that is easy to operate, noiseless, and positioned.
In order to achieve the above purposes, the present invention comprises: a cap having a plurality of male buckles at the front end; a visor having a plurality of female buckles at the inner end and an alcove at the outer end; and a lens, by means of a fixing member Fixing with the visor, the inner end has a tab in the middle; and the visor and the two sides of the lens have corresponding concave holes and convex bodies, and the outer end of the visor The two sides have a retaining wall to achieve the function of the lid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment, together with the accompanying drawings, details the structural features of the present invention and its effects as follows, so that it is easy to understand and recognize.
Please also refer to the first to fifth figures. This creative system contains:
a cap 1 having a plurality of male buckles 11 at the front end;
A visor 2 (or a bracket, which is represented by a visor in the following description), the inner end has a plurality of female snaps 21 for fastening with the male snaps 11, and each side of the inner end has a recess 22, The outer end of the bill 2 has an alcove 23 in the middle, and each side of the outer end has a front and rear recess 24, 25 and a retaining wall 26, and the retaining wall 26 is located at the front and rear recesses 24, 25. And a lens 3 having an arc-shaped concave shape, which is fixed to the visor 2 by a fixing member 31 (for example, a rivet), and has a tab 32 at the inner end and a convex body 33 at each side of the inner end. It can be embedded in the front and rear recesses 24, 25 of the visor.
According to the above configuration, the lens 3 is fixed to the visor 2 by the fixing member 31, and the visor 2 is fastened to the cap 1 so that the lens 3 is attached to the front end of the cap 1. In the normal state, the lens 3 is in a closed state. As shown in the second to fifth figures, the lens 32 of the lens is in the concave chamber 23 of the visor, and the convex body 33 is embedded in the front concave hole 24. To cover the lens 3.
If the lens 3 is to be applied, the lens 3 can be moved upward by hand pressing the lens 3, and the convex body 33 can be released from the front concave hole 24 and then inserted into the rear concave hole 25, so that the lens 3 can be opened, such as the sixth and seventh. As shown, the top edge of the lens 3 is now blocked by the retaining wall 26. On the contrary, if the lens 3 is moved down again, the convex body 33 is removed from the concave hole 25 and then inserted into the front concave hole 24, the lens 3 can be closed and restored, and the state shown in the second to fifth figures can be restored.
The operation of the above-mentioned lens 3 lid positioning is worth mentioning:
(1) The cover of the lens 3 is positioned on the one hand by the convex body 33 embedded in the front concave hole 24, and on the other hand, by the protrusion 32 in the concave chamber 23 for reinforcing the auxiliary positioning, by using the concave chamber 23 as The lens 3 is closed to the lower limit of the downward movement; on the contrary, the lens 3 is opened, on the one hand, the convex body 33 is embedded in the rear concave hole 25, and on the other hand, the top wall of the lens 3 is blocked by the retaining wall 26 to borrow The retaining wall 26 serves as the upper limit of the upper surface of the lens 3.
(b) As shown in the third figure, the two sides of the inner side of the bill 2 have a concave portion 22, so that the two sides of the bill 2 and the cap 1 form a state in which the outer surface is fitted but the inner portion is hollow. The fully flattened fitting state, so that the two sides of the visor 2 have elasticity, so that when the lens 3 is displaced up and down by force, the elastic offset portion can be applied to force the lens 3 to smoothly squat or lower. The cover and the visor 2 are firmly fastened to the cap 1 so as not to cause a drop due to excessive force.
(3) The creation is mainly between the visor 2 and the two sides of the lens 3, and has corresponding concave holes and convex bodies which can be fitted to each other, thereby achieving the purpose and effect of locating the cover, and therefore, the concave The number of holes is not limited to only the front and rear recessed holes, or there may be only one rear recessed hole, and the front, middle and rear recessed holes are all feasible, and the recessed holes may also be provided on the lens. The visor has a convex body and is also practicable. Therefore, any such structural changes should still be considered to be included in the scope of this patent.
Therefore, it can be seen from the above description that the present embodiment has at least the following advantages and effects, and is far more advanced than the prior art.
1. The construction is simple and consists only of the visor 2 and the lens 3.
2. The assembly is easy, the visor 2 is fixed to the lens 3, and then fastened to the cap 1 for assembly.
3. Easy to operate and no noise.
4. The positioning of the lid is true, and there is no defect that the automatic flap is generated due to the wind.
5. The cost of mold opening is reduced. Except for the mold of the visor and the lens, it is not necessary to open other accessory molds, and the cost of the visor mold is not increased.
To sum up, the specific structure disclosed in this creative embodiment is found to be nothing for the practitioners, and can achieve the intended purpose and effect. It can be called a novel and progressive creation, and proposes a new type according to law. patent application.
