[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] A helmet comprises a helmet shell, a cap lining and a chin strap 2. The chin strap 2 is detachably connected to the cap lining. According to different styles of helmets, the cap lining generally comprises a cap hoop band 1, a top band, a protective band, a support band and a sweat-absorbing band. The cap hoop band 1 is one of the main components of the cap lining and is generally made of plastic or metal. It tightly surrounds the wearer's head and has a certain degree of elasticity and can be adjusted according to the shape and size of the head. The function of the cap hoop band 1 is to provide a certain pressure to disperse the impact force and reduce the impact on the head. The top band is a lining band that directly contacts the top of the head and is generally made of soft materials, such as cotton, sponge, etc., to provide additional cushioning and comfort. The top band and the helmet shell can be connected by rivets, sockets or other methods. The protective band is a lining band located between the cap hoop band 1 and the top band, which can provide additional protection and support and reduce the pressure on the head when it is impacted. The protective band is generally made of soft materials, such as sponge, foam, etc. The support strap is a lining at the back of the head that provides extra support and stability, keeping the helmet more securely on the head. The support strap is usually made of a hard material, such as plastic or metal. The sweatband is a lining at the forehead that absorbs sweat and prevents it from flowing into the eyes or neck. The sweatband is usually made of a highly absorbent material, such as cotton or fleece.

[0021] At least three connecting blocks 1a are provided on both sides of the cap lining. Figure 1 Specific reference Figure 1 and Figure 2 As shown, the hat hoop band 1 includes a fixed band and an adjustable band. The fixed band is a fixed part surrounding the wearer's head, and the adjustable band is based on the fixed band, and is connected by an adjustable buckle or clasp, so that the band can be retracted and adjusted according to the size of the head. This design allows the hat hoop to better adapt to people with different head shapes, and improves the comfort and safety of wearing. The fixed band includes a left part 1b and a right part 1c, and the left part 1b and the right part 1c are each provided with three connecting blocks 1a, and the connecting blocks 1a of the left part 1b and the connecting blocks 1a of the right part 1c are symmetrically arranged relative to the midline of the length direction of the fixed band. As shown Figure 2 and Figure 3 As shown, a buckle 3 is provided at each end of the chin strap 2 .

[0022] Figure 3 Shown in the figure is a schematic diagram of the connection between a single-point chin strap 2 and a hat hoop 1, wherein a buckle 3 at one end of the chin strap 2 is connected to a connecting block 1a on one side of the hat lining, and a buckle 3 at the other end of the chin strap 2 is connected to a connecting block 1a on the other side of the hat lining.

[0023] Figure 4What is shown is a schematic diagram of the connection between the double-point chin strap 2 and the hat hoop ring strap 1, two buckles 3 are respectively provided at both ends of the chin strap 2, and the distance between the two buckles 3 is greater than the distance between the two connecting blocks 1a with the largest distance on the same side of the hat lining, the two buckles 3 at one end of the chin strap 2 are connected to the two connecting blocks 1a on one side of the hat lining, and the two buckles 3 at the other end of the chin strap 2 are connected to the two connecting blocks 1a on the other side of the hat lining.

[0024] The chin strap 2 has a first connection end and a second connection end, the first connection end has a first belt loop 2a with a fixed circumference, and the second connection end has a second belt loop 2b with an adjustable circumference. The buckle 3 has a first connection hole for connecting with the connection block 1a and a second connection hole for connecting with the chin strap 2.

[0025] Reference Figure 3 As shown, the belt body of the first belt ring 2a and the belt body of the second belt ring 2b are respectively connected to a buckle 3 through the second connecting hole.

[0026] Reference Figure 4 As shown, the chin strap 2 also includes an auxiliary strap 2c, both ends of which are connected to a buckle 3 through a second connecting hole, and the first belt loop 2a and the second belt loop 2b are each provided with one of the auxiliary straps 2c.

[0027] Reference Figure 5 As shown, the cap liner also includes a cap hoop, which is provided with two front connecting straps and two rear connecting straps 4 for connecting with the fixing strap, and the rear connecting straps are slidably connected to the ends of the fixing strap.

[0028] The end of the fixing belt is provided with a slide groove 5, and the rear connecting belt 4 is provided with an active buckle 4a that cooperates with the slide groove. By adjusting the position of the active buckle 4a in the slide groove 5, the position of the connection between the rear connecting belt 4 and the fixing belt is adjusted, and finally the size of the headband is adjusted to adapt to the wearing of people with different head circumferences.

[0029] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
