[0002] A child safety seat in a car, also known as a child restraint system, is a seat designed specifically for children of all ages and weights. It can effectively improve the safety of children. When a vehicle collides or suddenly decelerates, it should minimize the impact on the child and restrict the child's movements to minimize the degree of injury and ensure the child's safety.

[0003] After the existing child safety seat is fixed, the support structure needs to be operated with both hands when adjusting the height. One hand presses the button and the other hand pulls the support rod for adjustment, which is inconvenient to use. In addition, there is no protection for the support rod in the existing support structure, which is easy to cause wear of the support rod when adjusting the height. Therefore, a support structure of a child safety seat is urgently needed to solve the above problems. Utility Model Content

[0023] A support structure of a child safety seat comprises a seat body 1, a fixed head 2 is fixedly connected to the bottom of the seat body 1, a fixed bolt 4 is fixedly connected to the inside of the fixed head 2, an upper support rod 3 is fixedly connected to the inside of the fixed head 2, a protective cover 10 is movably connected to the surface of the upper support rod 3, a lower support rod 7 is fixedly connected to the outer surface of the protective cover 10, a fixed seat 5 is fixedly connected to the outer surface of the lower support rod 7, an adjustment structure 6 is arranged inside the fixed seat 5, the adjustment structure 6 comprises a button 61, a spring 62 is fixedly connected to the surface of the button 61, a connecting rod 63 is fixedly connected to the surface of the connecting rod 63, a conical head 64 is fixedly connected to the surface of the conical head 64, A protrusion 65 is movably connected to the surface, a spring 2 66 is fixedly connected to the surface of the protrusion 65, a limit rod 67 is fixedly connected to the surface of the protrusion 65, a support base 8 is fixedly connected to the bottom of the lower support rod 7, a bolt 9 is movably connected to the surface of the support base 8, an adjustment structure 6 is provided, and the button 61 is pressed, the button 61 drives the connecting rod 63 to move inward, so that the conical head 64 is inserted into the protrusion 65 to pull the protrusion 65 backward, so that the protrusion 65 is separated from the circular groove on the surface of the upper support rod 3, so as to adjust the height. A protective cover 10 is added between the upper support rod 3 and the lower support rod 7 to reduce the friction between the two rods when adjusting the height, prevent wear and collision, and increase the service life.

[0024] Furthermore, a circular groove 1 is provided on the surface of the fixed head 2, and a circular groove 2 is provided on the upper surface of the upper support rod 3. The fixing bolt 4 passes through the circular groove 1 and the circular groove 2 to fix the fixed head 2 and the upper support rod 3 to fix the upper support rod 3 under the seat body 1.

[0025] Furthermore, a square groove is provided on the surface of the fixing seat 5, and the button 61 is movably connected in the square groove. A limiting plate is provided at one end of the button 61 close to the spring 1 62, one end of the spring 1 62 is fixedly connected to the surface of the limiting plate, and the other end of the spring 1 62 is fixedly connected to the inner wall of the square groove. The limiting plate prevents the button 61 from being squeezed out of the square groove due to the force of the spring 1 62.

[0026] Furthermore, a groove having the same shape as the conical head 64 is formed on the surface of the protrusion 65, and the conical head 64 can be inserted into the groove. One end of the spring 66 is fixedly connected to the surface of the protrusion 65, and the other end of the spring 66 is fixedly connected to the inner wall of the fixing seat 5. The spring 66 applies outward pressure to the protrusion 65.

[0027] Furthermore, a circular groove three is formed inside the fixing seat 5 , and the limiting rod 67 can slide in the circular groove three. The limiting rod 67 ensures that the movement of the protrusion 65 will not be offset.

[0028] Furthermore, a plurality of slots are provided at the lower portion of the upper support rod 3 , and the shape and size of the protrusion 65 are consistent with the plurality of slots, and the spacing between the plurality of slots is the adjustable height.

[0029] Furthermore, the protective cover 10 is fixedly connected to the inner wall of the lower support rod 7, and the outer wall of the upper support rod 3 fits with the inner wall of the protective cover 10, so as to prevent wear and collision when adjusting the height between the two rods and increase the service life.

[0030] Working principle: The seat body 1 is fixed on the car seat. At this time, a supporting structure is required to fix the seat body 1 for a second time. The button 61 is pressed, and the button 61 moves toward the inside of the fixing seat 5, driving the connecting rod 63 to move inward, so that the conical head 64 moves and is inserted into the groove on the surface of the protrusion 65. The protrusion 65 is pulled out of the groove on the surface of the upper support rod 3, and the lower support rod 7 can be pulled to adjust the height. The height adjustment can be completed with one hand. When the button 61 is at a suitable position, the elastic force applied by the spring 2 66 to the protrusion 65 presses the protrusion 65 into the groove. The elastic force applied by the spring 1 62 to the button 61 causes the conical head 64 to move out of the protrusion 65. The limit plate on the surface of the button 61 prevents the button 61 from sliding out of the fixing seat 5 due to the force of the spring 1 62. The support base 8 is fixed by the bolt 9. The protective cover 10 arranged between the upper support rod 3 and the lower support rod 7 can protect the two rods to prevent the two rods from being directly rubbed and damaged or bumped, thereby increasing the service life.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
