Detailed Description

The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements and techniques of the present invention so that advantages and features of the present invention may be more readily understood when implemented in a suitable environment. The following description is an embodiment of the present invention, and other embodiments related to the claims that are not explicitly described also fall within the scope of the claims.

FIG. 1 shows a schematic representation of a bridge arch mask headgear.

As shown in fig. 1, the arch bridge type mask head band comprises two connecting arms 1 and a bandage 2, wherein the two connecting arms 1 are parallel to each other and extend along the front-back direction, the rear ends are connected with each other through the bandage 2, and the front ends are respectively connected with the two sides of a mask; the two connecting arms 1 are oppositely bent, and the curvature is matched with the shape of the head of a wearer; the middle of the connecting arm 1 is bent to form a camber arch 11; the arch 11 is dimensioned such that it can be moved away from the ear of the wearer in the worn state.

The headband, be applicable to the face guard that needs to be fixed at the wearer face, be particularly useful for eye-shade type welding face guard.

The connecting arm 1 is made of plastic and other materials with molding functions and partial elasticity. The connection of the connecting arm 1 to the mask is a flexible connection, for example, a knitted connection or an articulated connection, to adapt to different head circumferences of the wearer. The binding band 2 is a combination of a fabric band and a loose and tight band, has good elasticity and is used for fastening the mask on the head of a wearer. The front, back, left, right, up and down are based on the head of the wearer.

Two linking arm 1 are crooked in opposite directions, and the curvature and the adaptation of wearer's head shape, when wearing, linking arm 1 and the facial laminating of wearer provide great area of contact, reduce local pressure.

The camber 11 that forms in the middle of linking arm 1 can avoid the position of wearer's ear for when wearing the state, not form the oppression to the ear, improve wearer's experience.

The arch 11 may be in the shape of a circular arc, an elliptical arc, a square, etc., and is symmetrical in the front-rear direction of the head of the wearer to balance the center of gravity thereof.

When wearing, the front end of connecting arm 1 connects the face guard, and the rear end is taut by bandage 2, and connecting arm 1 receives the ascending pulling force in fore-and-aft direction, because its elasticity that bends and itself towards the wearer's head to laminate in wearer's head. When the degree of tightness of wearing needs to be adjusted, the length of the binding band 2 can be adjusted.

Fig. 2 shows a schematic view of the structure of the arch.

As shown in fig. 2, the arch 11 includes a first portion 111 and a second portion 112 connected to each other, the first portion 111 is provided with a sliding slot, and the second portion 112 is provided with a sliding piece embedded in the sliding slot and capable of sliding along the sliding slot in the front-back direction; a limiting column is arranged in the sliding groove, and a plurality of limiting holes matched with the limiting column are formed in the sliding sheet.

The arch 11 is divided into two parts, the first part is connected with the joint of the mask, the second part is connected with the bandage, and the connecting structures matched with each other, namely a sliding groove and a sliding sheet are respectively arranged at the connecting position of the first part 111 and the second part 112 to form the adjusting structure of the length of the connecting arm 1. The setting position of spout and gleitbretter can be exchanged, nevertheless the utility model discloses in, set up the spout at first portion 111 for when adjusting 1 length of linking arm, because the part light in weight that gleitbretter one end is connected, can make the face guard be in stable state, and this part that makes light in weight removes and accomplishes the regulation.

The tail end of the sliding chute, namely the tail end of the first part 111, is provided with a tightening part with a smaller caliber, the tail end of the sliding piece is provided with a locking part, and the outer diameter of the locking part is larger than the inner diameter of the tightening part, so that the sliding piece is locked at the farthest end of the sliding chute, and the sliding piece is prevented from falling off when the length of the connecting arm 1 is adjusted.

When the length of the connecting arm 1 is adjusted, different limiting holes in the sliding sheet are switched to the limiting columns, and the operation can be completed.

The utility model discloses in, the length adjustment mechanism who sets up on the camber arch 11 further makes the bandeau be applicable to the person of wearing of different head circumferences.

Fig. 3 shows a schematic view of the chute arrangement position.

As shown in fig. 3, the sliding groove is provided on the side of the arch 11 facing away from the head of the wearer. That is, the surface of the arch 11 facing the head of the wearer is a flat surface, and the installation of the chute does not affect the adhesion between the arch 11 and the head of the wearer.

According to the utility model discloses an embodiment, the spout is close to wearer's head one side and keeps away from the crisscross exhaust hole that is provided with in wearer's head one side.

For example, a first exhaust hole facing the outer side of the head of a wearer is formed at the tail end of the sliding groove, meanwhile, a second exhaust hole facing the inner side of the head of the wearer is formed adjacent to the tail end, the second exhaust hole is formed to the position where the sliding piece can penetrate into the bottommost part of the sliding groove, the sliding piece can be prevented from blocking the flexibility of the sliding piece due to accumulated gas due to good sealing performance when the sliding piece slides towards the inner part of the sliding groove, and the adjusting position can be visually observed.

According to an embodiment of the present invention, the connecting arm 1 is sheet-shaped. The flaky connecting arm 1 is attached to the head of a wearer, so that the local pressure is reduced, and the wearing experience is improved.

According to one embodiment of the invention, the connecting arm 1 is bent upwards or downwards to form a camber 11. The theoretical bending of the connecting arm 1 can be changed from upward bending to downward bending from the rotation towards the outer side of the head of the wearer along the connecting line of the two ends of the connecting arm 1. However, the present invention is preferably curved upward or downward, and particularly preferably curved upward.

When the arch 11 is bent upward or downward, the side surface thereof can be fitted to the head of the wearer, thereby relieving the local pressure. When the arch 11 is bent upward, it is possible to avoid a bad feeling of being attached to the wearer's face when bent downward.

According to the utility model discloses an embodiment, linking arm 1 forms camber 11 to the outside bending camber 11 when the camber is bent to the outside, can form the protection casing to the wearer's ear.

The joint connected with the mask bends outwards, so that the problem that when the mask is connected, an inward bulge is formed at the position of the joint, and the poor wearing experience of a wearer is caused can be avoided.

According to an embodiment of the present invention, the rear end of the connecting arm 1, the joint connected to the binding band 2 is in a shape of a Chinese character 'mu'. The problem that the elastic band is slowly loosened by self when the elastic band is stretched for multiple times can be avoided.

Figure 4 shows a schematic view of a mask.

As shown in fig. 4, a mask, comprising a bridge arch mask headgear of any of the foregoing.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim.
