[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is provided with a fitting groove having an insertion hole at its central portion and insertion grooves extending vertically downward on both sides, and a circular groove is formed on the fitting groove wall at the central portion. It has a U-shaped body with protrusions and linear protrusions on the groove walls of the insertion grooves on both sides, and two sandwiching pieces that are extended and bent in parallel. On the outer surface of one of the sandwiching pieces, there is a U-shaped sandwiching body with slightly protruding teeth, a slightly shorter connecting end and a slightly longer inserting end, and both sides of the inserting end are The L-shaped connecting piece is provided with aligned fitting teeth, and a connecting hole at the connecting end and a patch plate extending to the end.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is an assembly view of an embodiment of the present invention, FIG. 2 is an exploded view of a combination part of an embodiment of the present invention, FIG. 3 is a sectional view of a combination part of an embodiment of the present invention, and FIG. It is a figure showing the assembly state of one Example of a device.

As shown in FIG. 2, the connecting structure of the safety mask and the helmet according to one embodiment of the present invention is composed of a U-shaped main body 10, a U-shaped clip 12 and an L-shaped connecting piece 14. On both sides of the U-shaped body 10, an insertion groove 101 is provided which extends vertically downward and has an insertion hole 102 formed therein, and a linear protrusion 103 is formed on the groove wall of the insertion groove 101. Is provided. In addition, a cone-shaped fitting piece 104 having an appropriate length is extended on the bottom side of the two insertion grooves 101, and at the same time, a fitting hole 106 is formed at the central portion of the U-shaped body 10 so as to have a vertical insertion hole 106. A groove 105 is provided, and a circular protrusion 107 is provided on the groove wall of the fitting groove 105.

The U-shaped clip body 12 has two clip pieces 121 and 122 which are bent so as to extend in parallel, and one of the clip pieces 121 has an outer surface that is slightly protruded. 123 is provided. The L-shaped connecting piece 14 is extended to have a slightly shorter connecting end 141 and a slightly longer inserting end 142, and both side surfaces of the inserting end 142 are provided with aligned fitting teeth 143, and the connecting end 141 is provided at the connecting end 141. A mounting plate 144 and a patch plate 145 extending to the end are provided.

As shown in FIGS. 3 and 4, when the mask and helmet according to one embodiment of the present invention configured as described above are used in combination, first, the mounting hole 144 of the connecting end 141 of the connecting piece 14 is masked. Align them with the mounting holes at the ends of the peripheral edge 2 of 1 and connect them together with the connecting button. The U-shaped main body 10 is placed at an appropriate position on the side of the helmet 3, and the pyramidal stoppers 104 extending on both sides of the U-shaped main body 10 are inserted and fixed in the recess 401 of the helmet peripheral edge.

Then, the gripping piece 121 of the U-shaped gripping body 12 having the fitting teeth 123 is inserted into the insertion groove 101 on the side of the U-shaped main body 10, and the fitting teeth 123 on the surface and the groove wall of the insertion groove 101 are inserted. The U-shaped nips 12 are fitted to the U-shaped main body 10 by fitting the protrusions 103 together. Therefore, the U-shaped clip 12 is tightly fitted to the peripheral edge of the helmet 3, and finally the insertion end 142 of the L-shaped connecting piece 14 connected to the side of the helmet 1 is fitted to the center of the U-shaped body 10. When it is inserted into the groove 105, the combination of the mask 1 and the helmet 3 is completed. When the mask 1 is moved downward, the connecting piece 14 is blocked by the contact plate 145 and stops at an appropriate position so that it does not slide down.

In the design of the above embodiment of the present invention, when the insertion end 142 of the connecting piece 14 is inserted into the fitting groove 105 of the U-shaped body 10, the fitting teeth 143 on the surface and the projection 1 of the fitting groove 105 are inserted. 07 are pressed against each other. Therefore, the L-shaped connecting piece 14 can be moved up and down in the fitting groove 105 to adjust the vertical position of the mask 1, and it is possible to meet the need of protection for different applications.

[0011]

[Effect of device]

 As described above, the present invention has the features that the combination is simple, the vertical position of the mask can be adjusted, and the horizontal position can be adjusted appropriately.
