Description

Simple headband check ring joint structure

Technical field

This utility model belongs to personal protection apparatus field, connects particularly for the simple headband snap ring of canister respirator Structure.

Background technology

The headband check ring joint structure of canister respirator is the important component part of canister respirator headband fixed system, by it Special structure design can reduce the parts of mask fixed system and be easy to mask to assemble.

Currently, use the headband fixed system that domestic and international canister respirator is used more headband buckle, headband ring and cover body head With the structural shape that pawl is connected, its assembling parts is more, and assembling is wasted time and energy, and the removing of headband is relatively complicated, and mask Headband buckles easy to fall off, fracture, the easy drawing crack of headband pawl.

The content of the invention

This utility model in order to solve the problems, such as headband assembling waste time and energy remove with headband it is relatively complicated, there is provided it is a kind of The simple headband check ring joint structure of full face formula canister respirator is applied to, and improves the uniformity that mask wears stress.

This utility model adopts the following technical scheme that realization：

A kind of simple headband check ring joint structure, including headband pawl and headband ring；The headband pawl top opens up dead slot, Its left surface middle part offers headband ring draw-in groove and skewed slot, and its right flank bottom opens up eyeglass draw-in groove, the upper end of the headband pawl Head lateral bend to the left；In headband ring draw-in groove of the side checkpost of the headband ring loaded on headband pawl.

The dead slot hollow structure of its end of headband pawl can not only mitigate the weight of headband structure but also can improve headband pawl end Elasticity be easy to the handling of headband, the skewed slot of headband pawl to improve the elasticity of headband pawl, the eyeglass draw-in groove of headband pawl will be stuck in mirror The prominence at piece edge can not only play positioning but also can just with assembling.When using, the headband check ring joint structure is applied to entirely Face formula canister respirator, as shown in fig. 6, being assemblied in the lens edge bottom of full face formula mask using the eyeglass draw-in groove of headband Snap ring structure Portion, the assembling of two head band clasp symmetrical configurations.Headband from the beginning band inner side directly through, you can complete assembling.During removing mask, The dead slot position of headband pawl top ends is broken laterally, makes headband and headband ring have gap, loosen so as to reach headband, so as to remove Mask.

The present invention has the advantage that compared with prior art：

1st, headband is buckled and solves the problems, such as that headband assembling is loaded down with trivial details before comparing, and headband check ring joint structure is used directly Headband ring is placed at the middle part draw-in groove of headband pawl, from the beginning headband completes assembling by band inner side is directly worn, and reduces head The part of band structure, simple structure is easy to assembly, reduces the labor intensity of workman, reduces labor time, reduces cost.

It is convenient when the 2nd, removing mask to operate, break laterally at the dead slot on headband card top during removing mask, make headband and head Band has gap, loosens so as to reach headband, easily removes mask, compares former removing mode, simple and convenient.

Simple headband check ring joint structure of the present utility model only needs headband ring to assemble compared with traditional headband structure On its draw-in groove, its simple structure, parts are few, be easy to assembling, reduces cost；The cooperation of also correct band and its draw-in groove and The structure of headband pawl is studied, and headband wears convenient, and stretching when wearing is worn, and only needs outwards gently to break dead slot when unloading , make mask headband be more easy to loosen, it is more easy to remove mask.

Specific embodiment

Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

A kind of simple headband check ring joint structure 100, including headband pawl 1 and headband ring 2.

As shown in Figure 3,4, the top of headband pawl 1 opens up dead slot 14, and its left surface middle part offers headband ring draw-in groove 11 With skewed slot 12, its right flank bottom opens up eyeglass draw-in groove 13, the upper end of the headband pawl 1 lateral bend to the left.

The structure of headband ring 2 is as shown in Figure 5.

As shown in Figure 1, 2, in headband ring draw-in groove 11 of the side checkpost of the headband ring 2 loaded on headband pawl 1, the headband ring With the perpendicular assembling of headband pawl.

The headband Snap ring structure it is specifically used as shown in fig. 6, the eyeglass draw-in groove 13 of headband Snap ring structure 100 is assemblied in entirely The full edge bottom of face formula eyeglass 4 of face formula mask, the symmetrical assembling of two head band clasp structure 100.2 turns of headband ring is assigned in headband card On 1, headband from the beginning band inner side directly through, you can complete assembling.During removing mask, the top ends of headband pawl 1 are broken laterally The position of dead slot 14, makes headband and headband ring have gap, loosens so as to reach headband, so as to remove mask.

During concrete preparation, whether the depth of headband ring draw-in groove 1 of headband pawl and the height of both sides boss can all affect assembling Conveniently, skewed slot 2 and dead slot 4 can all affect the flexibility of headband pawl so as to affect headband assembling and the removing of mask, eyeglass draw-in groove 3 Design should ensure that the assembling of the toughness of headband pawl correct strip slip-collar again plays positioning and fixation；Headband ring will be placed on At the headband ring draw-in groove 1 of headband pawl, headband from the beginning band inner side directly through, you can complete headband assembling, it is critical only that headband The structure of ring is designed with size, should ensure that easily assembling ensures again the fixation to headband to headband.

Finally it should be noted that above example is only to illustrate the technical solution of the utility model and unrestricted, although It has been described in detail with reference to this utility model embodiment, it will be understood by those within the art that, to this utility model Technical scheme modify or equivalent, without departure from the spirit and scope of the technical solution of the utility model, its is equal During claims of the present utility model should be covered.
