[0031] In a first aspect, the embodiments of the present application provide a safety belt length adjusting structure, which will be described with reference to Figure 1 The safety belt length adjusting structure comprises a chair body 1, a belt body 2 and an adjusting connecting piece 3. The chair body 1 is provided with a mounting structure, one end of the belt body 2 is connected to the chair body 1 and can be adjusted in extension and retraction, and the other end of the belt body 2 can be detachably mounted at the mounting structure; the adjusting connecting piece 3 is adapted to be fixedly connected to the chair body 1, the adjusting connecting piece 3 is arranged in space from the mounting structure, and the end of the belt body 2 connected to the mounting structure can be detachably connected to the adjusting connecting piece 3; when the belt body 2 is connected to the adjusting connecting piece 3, the extension and retraction adjusting length of the belt body 2 is smaller than the length when the belt body 2 is connected to the mounting structure.

[0032] With reference to Figure 2 The belt body 2 is provided with a buckle 21, and the belt body 2 is adapted to slide relative to the buckle 21, so that the belt body 2 can be adjusted in extension and retraction at different positions. The buckle 21 is connected to a connecting safety belt, and the connecting safety belt is adapted to be connected to the chair body 1. The two belt bodies 2 are symmetrically and spaced apart, and the two belt bodies 2, the buckle 21 and the connecting safety belt are combined to form a five-point safety belt. The adjusting structures of the two belt bodies 2 are the same, and one of the belt bodies 2 will be described below.

[0033] The belt body 2 can be divided into a shoulder safety belt 22 and an abdominal safety belt 23 by the buckle 21, the shoulder safety belt 22 protects the shoulders of the occupant, and the abdominal safety belt 23 protects the abdomen of the occupant. One end of the shoulder safety belt 22 away from the abdominal safety belt 23 is connected to the chair body 1 in extension and retraction; one end of the abdominal safety belt 23 away from the shoulder safety belt 22 is connected to the mounting structure.

[0034] In combination with Figure 1 With reference toFigure 2 With Figure 3 The abdominal safety belt 23 is provided with a safety belt grommet 24 (the grommet is prior art, i.e. a part with a cross section in the shape of a "sun" which will not be described in detail here) made of high-strength metal material. The end of the abdominal safety belt 23 is bent and sewn to form a connecting grommet 25, and the safety belt grommet 24 is located on the connecting grommet 25. The abdominal safety belt 23 is connected to the mounting structure or to the adjusting connector 3 through the safety belt grommet 24.

[0035] In combination Figure 1 With reference to Figure 2 With Figure 3 The chair body 1 is provided with a safety belt inlet 11 and a safety belt outlet 12, and the safety belt outlet 12 is located in the direction close to the other side of the safety belt inlet 11. The safety belt inlet 11 and the safety belt outlet 12 both penetrate the chair body 1, and the width of the safety belt inlet 11 and the safety belt outlet 12 is greater than the thickness of the safety belt grommet 24 and the thickness of the flat connecting grommet 25. The end of the safety belt grommet 24 and the connecting grommet 25 penetrates the safety belt inlet 11 and then penetrates the safety belt outlet 12. When the safety belt grommet 24 is placed horizontally, the size of the outer surface is greater than the width of the safety belt outlet 12, so that the safety belt grommet 24 can be changed to a horizontal position after penetrating the safety belt outlet 12, and then the connecting grommet 25 is limited and installed, and the end of the abdominal safety belt 23 is not easy to separate from the safety outlet when the length of the shoulder safety belt 22 is adjusted.

[0036] The mounting structure is a mounting groove 13, and the safety belt outlet 12 is located in the mounting groove 13 and communicates with the mounting groove 13. The safety belt grommet 24 is fixedly installed in the mounting groove 13, and the safety belt grommet 24 does not protrude from the mounting groove 13, so that the surface of the chair body 1 is not easy to be uneven, which affects the comfort of the passenger.

[0037] In combination Figure 1 With reference to Figure 2 With Figure 3 The abdominal safety belt 23 is provided with a seam 26, and the thickness of the seam 26 plus the thickness of the flat connecting grommet 25 is greater than the thickness of the flat connecting grommet 25 alone, and the setting of the seam 26 can limit the length adjustment of the connecting grommet 25. Specifically, the thickness of the seam 26 is less than the width of the safety belt inlet 11 but greater than the width of the safety belt outlet 12, so that the seam 26 can penetrate the safety belt inlet 11, but cannot penetrate the safety belt outlet 12, thereby limiting the length adjustment of the connecting grommet 25. At the same time, such setting can hide the seam 26 at the bottom of the chair body 1, improving the appearance. In another embodiment, the thickness of the seam 26 is greater than the width of the safety belt inlet 11, i.e. the seam 26 cannot pass through the safety belt inlet 11.

[0038] In combinationFigure 3 Referring to Figure 4 With Figure 5 The adjusting connector 3 is arranged on the side of the safety belt outlet 12 away from the safety belt inlet 11 and is spaced from the safety belt outlet 12. The adjusting connector 3 is fixedly installed on the chair body 1. The adjusting connector 3 is a connecting carabiner. The connecting carabiner is provided with a connecting opening 31 in the outer wall, which is in communication with the carabiner. The size of the connecting opening 31 is greater than the thickness of the belt body 2 but less than the width of the belt body 2. The connecting belt ring 25 enters the inside of the connecting carabiner through the connecting opening 31 and is connected with the connecting carabiner. The connecting belt ring 25 is not easy to be separated from the connecting carabiner through the connecting opening 31, and the connection is stable. The above-mentioned connection process is simple in operation and convenient to adjust.

[0039] The chair body 1 is provided with a groove 14. The connecting carabiner is fixedly installed in the groove 14 and does not protrude from the groove 14, so that the surface of the chair body 1 is not concave-convex, and the connecting carabiner is made of high-strength metal material. In another embodiment, the adjusting connector 3 can be a metal hook.

[0040] The implementation principle of the safety belt length adjusting structure in the embodiment of the application is as follows: since the thickness of the safety belt carabiner 24 is less than the width of the safety belt inlet 11 and the safety belt outlet 12, and the size of the safety belt carabiner 24 after being placed horizontally is greater than the width of the safety belt inlet 11 and the safety belt outlet 12, after the safety belt carabiner 24 and the connecting belt ring 25 are pulled out from the safety belt outlet 12, the safety belt carabiner 24 can be placed horizontally on the chair body 1, so that the end of the connecting belt ring 25 is limited. The setting of the sewing line 26 makes the thickness at this position greater than the thickness of the flat connecting belt ring 25, and the thickness at the position of the sewing line 26 is greater than the width of the safety belt inlet 11 or the safety belt outlet 12, so that the belt body 2 is limited on the side away from the connecting belt ring 25 and is not easy to pass through the safety belt inlet 11 or the safety belt outlet 12, so that after the connecting belt ring 25 is connected with the adjusting connector 3, the length adjustment is limited, and the situation that the end of the connecting belt ring 25 is too loose to be separated from the adjusting connector 3 does not occur.

[0041] When the safety belt is still not well fitted to the baby even after the shoulder safety belt 22 is adjusted to the limit value in the tightened state, the adjusting connector 3 can be used as an auxiliary adjusting device. The connecting belt ring 25 is pulled to move the end of the connecting belt ring 25 from the safety belt carabiner 24 to the position of the adjusting connector 3, and the connecting belt ring 25 enters the inside of the connecting carabiner through the connecting opening 31 and is connected with the connecting carabiner. The above-mentioned adjusting process is equivalent to shortening the length of the belt body 2 for extension adjustment, so that the belt body 2 can be more fitted to the passenger with a smaller volume.

[0042] In a second aspect, the utility model provides a child safety seat, the child safety seat is equipped with the safety belt length adjusting structure in the first aspect, so that the safety belt adjusting has an auxiliary adjusting mechanism, and the safety belt can be conveniently adjusted according to actual conditions.
