The specific examples described in the following embodiments of the present invention are merely illustrative of specific embodiments of the present invention and do not constitute limitations on the scope of the invention.

The invention is further described with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1, fig. 1 is a schematic structural diagram of a headband according to a first embodiment of the present invention. The embodiment provides a headband 100, the headband 100 comprises a head circumference belt 1 contacting with the head circumference of a wearer and a top belt 2 contacting with the head circumference of the wearer, the head circumference belt 1 and the top belt 2 are connected to form the headband 100, and the headband 100 can be connected with protective equipment such as a welding mask or a safety helmet and the like for a welder to wear during welding or other dangerous operations.

In the present invention, the direction of the wearer's eyes who normally wears the headband 100 is the front, and the direction corresponding to the front is the rear. The normal wearing refers to a state of the welding mask when a welder performs a welding operation, that is, a state in which a mask shell of the welding mask is positioned right in front of eyes of the welder.

The headband 1 comprises a forehead band 11 and a neck pillow 12 connected with the forehead band 11, the forehead band 11 is in close contact with the forehead of a wearer, the neck pillow 12 is in close contact with the back of the head of the wearer, when the headband 100 is worn by the wearer, the headband 100 is fixed on the head of the wearer by the headband 1 with different tightening forces, and different pressures are brought to the head of the wearer.

In this embodiment, the occipital neck pad 12 is provided with a knob mechanism for adjusting the tightening force of the headband 1, but the knob mechanism may be provided on the forehead band 11, or may be provided at a middle connecting portion where the forehead band 11, the occipital neck pad 12, and the parietal band 2 meet.

As shown in fig. 2 and 3, wherein fig. 2 is a top view of the forehead strap of the headband shown in fig. 1; fig. 3 is a side view of the forehead strap of the headband of fig. 1. The forehead strap 11 includes a plurality of extensible parts 111 arranged at intervals and fixing parts 112 arranged between the adjacent extensible parts 111, and the extensible parts 111 automatically extend and retract when the head circumference 1 is tightened.

When the wearer wears the headband 100, the forehead band 11 is pulled to be tightened to both sides no matter the headband 11 is tightened by a knob mechanism, a gear mechanism or other means, so that the extensible part 111 is automatically extended and contracted when the headband 1 is tightened, the tightening force is dispersed, the headband 100 is fixed, the oppressive feeling of the tightened pulling force on the head of the wearer is reduced, and the wearing experience of the wearer is improved.

The telescopic part 111 is made of an elastic material and has certain elasticity, and when the head surrounding belt 1 is tightened, the telescopic part 111 automatically stretches; when the head shroud 1 is loosened, the telescopic portion 111 is automatically retracted.

The expansion part 111 is preferably formed to extend inward or outward from the end of two adjacent fixing parts 112. The inward extension refers to extension from the front to the rear, and the outward extension refers to extension from the rear to the front.

In this embodiment, the stretchable part 111 is a stretchable groove formed to extend inward, i.e., a V-shape, and is formed to extend outward, i.e., an inverted V-shape, but the stretchable part 111 is not limited to the shape, and may have other structures as long as it has a certain stretchability and can reduce the tension.

The fixing portion 112 is used to connect the extensible portions 111 and the occipital neck pad 12, and the extensible portions 111 may be used to connect the occipital neck pad 12. The fixing portion 112 is in close contact with the forehead of the wearer when worn.

In this embodiment, the fixing portion 112 and the stretchable portion 111 are uniformly distributed along the circumferential direction of the forehead belt 11, so that the stretching force is more uniformly dispersed, and the comfort of the wearer is improved. Of course, in other embodiments, the fixing portion 112 and/or the telescopic portion 111 may also be designed to have different distribution manners according to different stress positions, such as uneven distribution, or more telescopic portions 111 disposed at positions that are stressed more, and less telescopic portions 111 disposed at positions that are stressed less.

Further, the forehead strap 11 further includes a cushion sheet 113 disposed adjacent to the extensible part 111, and the cushion sheet 113 further cushions the tightening force, thereby reducing the discomfort of the wearer when the headband 11 is tightened.

As shown in fig. 2, at least one pair of the buffer pieces 113 are disposed on two sides of one of the fixing portions 112, the buffer piece 113 includes an extending portion 1131 connected to the fixing portion 112 and a buffer portion 1132 connected to the extending portion 1131, and the buffer portion 1132 contacts with the forehead of the wearer to prevent the forehead of the wearer from being pressed by too much tightening force. The number of the extension portions 1131 is two to provide sufficient support for the buffering portion 1132, and of course, the number of the extension portions 1131 may also be one or more, and adjacent extension portions 1131 may also be connected.

In this embodiment, the forehead strap 11 is one, the number of the cushion pieces 113 is 7, and the number of the stretchable parts 111 is 6, and in other embodiments, the number of the cushion pieces 113 and the number of the stretchable parts 111 may be flexibly designed according to the tightening manner of the forehead strap 11 and the stress of the wearer.

As shown in fig. 1, the top band 2 includes a left band 21 and a right band 22, the left band 21 and the right band 22 are connected to fix the headband 100 to the top of the head of the wearer, and the stretchable part 111 may be provided on the left band 21 or the right band 22 to reduce the feeling of pressure of the tightening force on the top of the head of the wearer. In the present embodiment, the top tape 2 is two strips arranged in parallel, but the number of the top tapes 2 is not limited thereto.

As shown in fig. 4, fig. 4 is a schematic structural diagram of a welding mask provided by the present invention. The utility model also provides a welding face guard, welding face guard includes face guard casing 200 and locates in face guard casing 200 bandeau 100. The mask shell 200 serves as the main body of the welding mask and provides protection for the head of a welder; the headband 100 secures the mask shell 200 to the head of a wearer.

When the mask is worn, the telescopic part 111 automatically extends and retracts, so that each part of the headband 100 is tightly attached to the head of a wearer with proper force, a uniform damping effect is provided for the mask shell 200, the headband 100 provides uniform support when being accidentally impacted by external force, sufficient safety protection is provided for the wearer, and the safety of the wearer is guaranteed.

Example two

As shown in fig. 5, fig. 5 is a schematic structural view of the forehead belt according to the second embodiment of the present invention. The forehead belt provided by the present embodiment is different from the forehead belt provided by the first embodiment only in that: the extension portion 111 is formed to extend outward, i.e. to be U-shaped, and if it is formed to extend inward, it is inverted U-shaped, and of course, the shape of the extension portion 111 is not limited, and may be any one or combination of U-shaped, inverted U-shaped, V-shaped, inverted V-shaped, or other shapes.

Meanwhile, at least one of the fixing portions 112 is the buffer sheet 113, so that the processing is more convenient and the structure is simpler. In this embodiment, the fixing portions 112 are the buffer pieces 113, and of course, the fixing portions 112 may also be the buffer pieces 113.
