Description

Technical Field

[0001] The utility model relates to the technical field of masks, in particular to a novel gas mask headband assembly. Background Art

[0002] Gas masks are used to protect the face and neck from flying metal debris, harmful gases, liquid splashes, and metal and hot solvent dust. They primarily include welding masks, impact masks, radiation masks, smoke and gas masks, and heat-insulating masks. Protective masks primarily provide a barrier or isolation function, so airtightness or a tight fit is crucial, especially for smoke and gas masks.

[0003] While the airtightness of a mask is crucial not only for the mask itself, the installation and use of its wearing components are also closely linked to its airtightness. However, traditional gas masks primarily utilize connecting rings at four ends of the mask's edge, through which the wearing cord is attached to the mask. These connections are relatively flimsy and prone to breakage, and the wearing cords must be individually adjusted before use, making it very cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0029] refer to Figure 1-6 , a new type of gas mask headband combination, including:

[0030] Shell 1, mounted on the outside of the protective mask;

[0031] The mounting mechanism comprises a set of through holes 2 provided on the left and right sides of the lower side of the housing 1 and a set of positioning holes 3 provided on the left and right sides of the upper side of the housing 1;

[0032] Two wearing ropes 4 are retractably mounted on the housing 1, with the middle portion of the wearing rope 4 being folded and arranged on the inner side of the housing 1, and the two ends thereof respectively passing through the through hole 2 and the positioning hole 3 on the same side and being placed on the outer side of the housing 1; the ends of the two wearing ropes 4 passing through the through hole 2 are connected, and the ends passing through the positioning hole 3 are connected;

[0033] A set of locking mechanisms are detachably mounted on the outside of the housing 1 and are used to adjust, fix and lock the corresponding wearing ropes 4.

[0034] The utility model uses a set of upper and lower through holes 2 and a set of positioning holes 3 to respectively install two wearing ropes 4, and then the corresponding ends of the two wearing ropes 4 are respectively connected; the wearing rope 4 is not only arranged on the inner side of the shell 1 and folded, so that the contact surface between the wearing rope 4 and the shell 1 is larger, and fits between the mask body 13 and the shell 1, thereby improving the stability of the installation of the wearing rope 4; it is also coordinated with the locking mechanism to adjust the fixed locking, and the length of the wearing rope 4 can be flexibly, conveniently and quickly adjusted, thereby improving its practical effect.

[0035] The through hole 2 is arranged horizontally, and the positioning hole 3 is arranged vertically. The utility model is used for wearing the rope 4 by the through hole 2 arranged horizontally and the positioning hole 3 arranged vertically, which can facilitate the wearing rope 4 to be folded and installed.

[0036] The locking mechanism includes an integrally formed mounting base 5 fixed to the outside of the shell 1, a buckling member 6 rotatably installed and buckled and fixed on the mounting base 5, and the end of the wearing rope 4 passing through the positioning hole 3 is connected above the mounting base 5 and pressed under the buckling member 6.

[0037] The mounting seat 5 includes a first limiting portion 501 and a second limiting portion 502 which are arranged at intervals and are used to limit the position of the wearing rope 4. The first limiting portion 501 is provided with a positioning rod 7 for installing the buckling member 6 and a clamping block 8 for fixing the buckling member 6.

[0038] The utility model provides two mounting seats 5 on the left and right sides of the outer side of the shell 1, through which the limiting wearing rope 4 is passed, and is rotatably installed on the mounting seat 5 and can be buckled and fixed with a buckling piece 6. When the buckling piece 6 is buckled and fixed to the mounting seat 5, the wearing rope 4 can be fixed to the mounting seat 5; when the buckling piece 6 is not buckled and fixed to the mounting seat 5, the wearing rope 4 can be pulled out, which not only facilitates the quick adjustment of the length of the wearing rope 4 and fixes it when the protective mask is worn, but also improves its practical effect.

[0039] The ends of the two wearing ropes 4 passing through the through hole 2 can be detachably mounted on both sides of the same adjustable elastic connector, and the adjustable elastic connectors are both fixedly connected to the wearing ropes 4 with adjustable lengths.

[0040] The ends of the two wearing ropes 4 passing through the positioning holes 3 can be detachably mounted on both sides of the same head wearing piece, and the head wearing piece can be fixedly connected to the wearing ropes 4 with adjustable length.

[0041] By utilizing the adjustable elastic connector and the head wearing piece to detachably and adjustably connect the ends of the two wearing ropes 4, it is not only convenient to wear and fix, but also the length of the wearing rope 4 can be easily adjusted.

[0042] A corresponding air vent is provided in the middle of the shell 1 between the through hole 2 and the positioning hole 3, and guide strips 9 are integrally formed and fixed on the outside of the air vent and spaced from top to bottom, and the guide strips 9 are gradually tilted downward from the inside to the outside.

[0043] A plurality of convex points 10 are arranged side by side and spaced apart on the housing 1 below the through hole 2. The convex points 10 are used to increase the friction between the wearing rope 4 and the housing 1, thereby effectively preventing the wearing rope from moving when the protective mask is worn.

[0044] The upper side of the housing 1 is provided with a limiting through hole 11 for limiting the installation of the mask body 13, and the inner side of the housing 1 is provided with a fixing member 12 for clamping and fixing the mask body 13. The coordinated arrangement of the limiting through hole 11 and the fixing member 12 can make the mask body 13 more securely installed and not easy to disassemble, thereby improving the applicability of the utility model and being applicable to masks with various functions.
