[0007] By adopting the above technical solution, the support seat can be installed flexibly and conveniently. At the same time, when a dangerous situation occurs, the seat belt can be slowly extended to limit the child to prevent the seat belt from strangling the child.

[0008] Furthermore, a damping rubber sleeve is adhered to both ends of the inner part of the rotating drum, and the damping rubber sleeve is wrapped around the outside of the rotating connection part of the inner rotating seat.

[0009] By adopting the above technical solution, the rotating drum can be rotated slowly, ensuring that the connecting belt can be extended slowly, thereby achieving a buffering operation.

[0010] Furthermore, a safety belt is provided at one end of the connecting belt, and the safety belt and the connecting belt are limitedly connected via a quick connection assembly.

[0011] By adopting the above technical solution, the safety belt can be quickly and conveniently disassembled and assembled, and the safety belt can be flexibly and conveniently replaced and cleaned.

[0012] Furthermore, the outside of the support seat is slidably connected to two sliders, the outer surfaces of the sliders are provided with threaded holes, and the inner threads of the threaded holes are threadedly connected to locking knobs.

[0013] By adopting the above technical solution, the slider can be limited and fixed by using the locking knob.

[0014] Furthermore, a support rod is rotatably connected to the upper surface of the sliding block, and a through groove is arranged on the outer surface of the support rod.

[0015] By adopting the above technical solution, it is ensured that the support rod can slide stably outward.

[0016] Furthermore, both ends of the support seat are respectively fixedly connected with a fixed end head, and the upper ends of the fixed end heads penetrate through the through grooves on the outer surface of the support rod.

[0017] By adopting the above technical solution, it can be ensured that the support rod expands outwards.

[0018] In summary, the beneficial technical effects of the utility model are:

[0019] 1. In the event of an emergency, the safety belt can be pulled by the connecting belt. Since one end of the connecting belt is wound and fixed on the outer surface of the drum, the pulling of the connecting belt can effectively drive the drum to rotate. During the rotation of the drum, the torsion spring and the damping rubber sleeve cooperate with each other to effectively prevent the drum from rotating rapidly, thereby slowly stretching the connecting belt, which can effectively buffer and prevent the safety belt from strangling children. At the same time, the structure can be fastened to the outside of the buckle block by the buckle strip, so that the structure can be quickly installed, and the overall practicality is effectively improved.

[0020] 2. The utility model can utilize a quick connection assembly to enable the connection belt and the safety belt to be quickly disassembled and connected, thereby conveniently replacing and cleaning the safety belt, and the practicality is further improved;

[0021] 3. The utility model can move the slider to slide on the support seat. Under the linkage of the fixed end, the two support rods extend outward, and then the position of the slider is fixed by the locking knob, so that the support rods can be firmly against the seat. At this time, the support rods can effectively support the side of the safety seat body, which can effectively improve the stability of the safety seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The method of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 A safety belt fixing structure for a child safety seat to prevent strangulation includes a safety seat body 1, and a buckle block 2 is integrally connected to the outer surfaces of the symmetrical sides of the safety seat body 1, a support seat 7 is installed on the back of the safety seat body 1, and a buckle strip 3 is fixedly connected to the two ends of the support seat 7, and the buckle strip 3 is buckled on the outside of the buckle block 2. Two fixed seats 8 are arranged on the support seat 7, and an inner rotating seat 12 is fixedly connected to the inner wall of the fixed seat 8. A rotating drum 13 is rotatably installed on the inner rotating seat 12, and a connecting belt 4 is wound and fixed on the outer surface of the rotating drum 13. A torsion spring 15 is arranged inside the rotating drum 13, and one end of the torsion spring 15 is fixedly connected to the inner wall of the rotating drum 13, and the other end of the torsion spring 15 is fixedly connected to the outer surface of the inner rotating seat 12. A damping rubber sleeve 14 is adhered to the two ends of the inside of the cylinder 13, and the damping rubber sleeve 14 is wrapped around the outside of the rotating connection part of the inner rotating seat 12, so that in an emergency, the safety belt 6 can pull the connecting belt 4. Since one end of the connecting belt 4 is wrapped and fixed on the outer surface of the rotating drum 13, the pulling of the connecting belt 4 can effectively drive the rotating drum 13 to rotate. During the rotation of the rotating drum 13, the mutual cooperation of the torsion spring 15 and the damping rubber sleeve 14 can effectively prevent the rotating drum 13 from rotating rapidly, so that the connecting belt 4 can be slowly stretched, which can effectively play a buffering role and prevent the safety belt 6 from strangling children. At the same time, the structure is buckled on the outside of the buckle block 2 through the buckle strip 3, which can realize the rapid installation of the structure, and the overall practicality is effectively improved.

[0028] Reference Figure 1A safety belt 6 is provided at one end of the connecting belt 4, and the safety belt 6 is limitedly connected to the connecting belt 4 by a quick connection component 5, wherein the quick connection component 5 can be used to quickly disassemble the connecting belt 4 and the safety belt 6, so that the safety belt 6 can be conveniently replaced and cleaned, and the practicality is further improved.

[0029] Reference Figure 2 The outside of the support seat 7 is slidably connected to two sliders 9, and a threaded hole is provided on the outer surface of the slider 9, and a locking knob is connected to the inner thread of the threaded hole. A support rod 11 is rotatably connected to the upper surface of the slider 9, and a through groove is provided on the outer surface of the support rod 11. The two ends of the support seat 7 are respectively fixedly connected to a fixed end head 10, and the upper end of the fixed end head 10 passes through the through groove on the outer surface of the support rod 11, wherein the slider 9 can be moved to slide on the support seat 7, and under the linkage of the fixed end head 10, the two support rods 11 extend outward, and then the position of the slider 9 is fixed by the locking knob, so that the support rod 11 can be firmly against the seat, and at this time, the support rod 11 can effectively support the side of the safety seat body 1, which can effectively improve the stability of the safety seat.

[0030] Working principle: When in use, first install the structure at the designated position, and when installing the safety seat body 1, slide the slider 9 on the support seat 7. Under the linkage of the fixed end 10, the two support rods 11 extend outward, and then use the locking knob to fix the position of the slider 9 so that the support rod 11 can be firmly against the seat. At this time, the support rod 11 can effectively support the side of the safety seat body 1, and then wear the safety belt 6. Once an emergency occurs, the safety belt 6 pulls the connecting belt 4. Since one end of the connecting belt 4 is wound and fixed on the drum On the outer surface of 13, the rotating drum 13 is rotatably sleeved on the outside of the inner rotating seat 12, and a damping rubber sleeve 14 is provided at the rotation connection between the rotating drum 13 and the inner rotating seat 12. A torsion spring 15 is provided inside the rotating drum 13, one end of the torsion spring 15 is fixedly connected to the inner wall of the rotating drum 13, and the other end of the torsion spring 15 is fixedly connected to the outer surface of the inner rotating seat 12. Therefore, when the connecting belt 4 pulls the rotating drum 13 to rotate, the rotating drum 13 can rotate slowly, thereby allowing the safety belt 6 to slowly extend, which can play a good buffering operation and effectively prevent children from being strangled.
