Description

helmet

technical field

The invention relates to a safety helmet, in particular to a safety helmet with a retractable buckle.

Background technique

Currently used safety helmets, including locomotives, bicycles, vehicles, work, military, or sports, etc., are mainly provided with a pair of helmet straps on the brims of both sides of the helmet. Each has a male and female buckle, and the helmet is fixed on the head by using the male and female buckle and the chinstrap. Traditionally, the chinstrap and the buckle of this kind of helmet are based on the needs of different users with different lengths. To adjust the position of the buckle on the chinstrap, in addition to the troublesome adjustment method, it is even more difficult to adjust to the tightness just suitable for the user. Therefore, in use, some people will adjust it at will for easy wearing. If the adjustment is too tight, the user will feel uncomfortable. If the adjustment is too loose, the meaning of wearing a helmet may be lost, especially when riding a bicycle. It is actually very dangerous if the safety helmet is not worn correctly and properly.

Detailed ways

Please refer to Figures 1 to 7, in the first preferred embodiment of the present invention, a safety helmet mainly includes a cap body 1, a first buckle belt 2, a second buckle 3 and a stopper Buckle 4.

Please refer to FIGS. 5-8 , the cap body 1 of the present invention is like a commercially available safety cap, which has a first side 11 and a second side 12 , and has a cushioning layer 13 inside, which is made of foam material.

1-3, 5-6, the first buckle 2 of the present invention is arranged on the first side 11 of the cap body 1, the first end 21 has a first buckle 23, the second end 22 Then connect an elastic body 24, the other end of the elastic body 24 is fixed in the cap body 1, the second end 22 of the first buckle 2 can move straightly inside and outside the cap body 1, and the first buckle 2 The second end of a buckle 2 can be resisted by the buckle 4 .

The aforementioned first buckle belt 2 then includes a Y-shaped first end 21 and a second end 22, the second end 22 has two belt bodies 25, and each is connected with an elastic body 24, and each of the elastic bodies 24 is another One end is respectively fixed in the cap body 1, and the second end 22 of the first buckle 2 can move straightly inside and outside the cap body 1, and can be buckled by the buckle 4 and fixed. .

The aforesaid buckle 4 in the present invention has a body plate 41, a pair of columns 42 perpendicular to the body plate, and a buckle 43 with a shaft between the pair of columns. The first buckle 2 and the second The end 22 passes between the body plate 41 and the buckle 43. When the buckle 43 of the buckle 4 is in the fastened position (see FIG. 5), the first buckle 2 is fixed, otherwise, when it is in the released position (See Fig. 6), the first buckle 2 can move freely, so the two ends 22 of the first buckle 2 can freely go in and out of the helmet body 1. Moreover, in the cap body 1 , corresponding to the movable positions of the second end 22 of the first buckle 2 and the elastic body 24 , a long slot 44 is provided for accommodating the second end 22 of the first buckle 2 and the elastic body 24 .

In addition, there is an opening 45 (see FIG. 6 ) at the front end of the buckle 4 , the first buckle 2 passes through the buckle 4 through the opening 45 , and the front end of the elastic body 24 cannot pass through the opening 45 . Only then will the elastic body 24 not go over the buckle 4 and affect the function of the first buckle 2 . Its methods mainly include:

1. The outer diameter of the elastic body 24 is larger than the opening 45;

2. There is a restriction 46 at the front end of the elastic body 24. For example, as shown in FIG. 5, a rivet is used as the restriction.

Furthermore, the buckle 43 end of the buckle 4 is provided with a pointed portion or a sawtooth portion 47 (see FIG. 2 ), so that it has a better fixing effect.

In the embodiment of the present invention, the aforementioned elastic body 24 mainly uses rubber or a composite material containing rubber (see FIG. 5 ) or uses a coil spring (see FIG. 8 ).

4-8, the second buckle 3 of the present invention is arranged on the second side 12 of the cap body 1, and can be buckled with the first buckle 23, and the second buckle 3 has A second buckle 31 , the second buckle 3 is fixed on the brim of the second side 12 of the cap body 1 by the second buckle 31 .

According to the concept of the present invention, when using the safety helmet of the present invention, as long as the safety helmet is put on, and the buckle 4 is released, the first buckle 2 is pulled down (outside) for a distance, and the elastic body 24 is stretched, and after the first buckle 2 passes through the user's jaw, the first buckle 23 and the second buckle 3 are buckled and let go, so that the first buckle 2 is pulled back by the elastic body 24, and the first buckle 2 is pulled back. The degree of tightness set by the first buckle 2 on the elastic body 24, and then the buckle 4 is fastened to the belt body 25 of the second end 22 of the first buckle 2, so that the first buckle 2 can be kept in a fixed position , and when desiring to take off the safety helmet, the buckle 4 is released, and then the first and second buckles are released. The elastic body 24 presets the tightness of the buckle belt of the safety helmet to an optimal value, so no further adjustment is required, which is very practical and convenient.

To sum up, the above is only a preferred implementation example of the present invention, and is not intended to limit the present invention; all other equivalent modifications or replacements that do not deviate from the present invention shall be included within the scope of the present invention.
