DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A reinforced children's bicycle tail rack in this embodiment includes a tail rack body 1, a connecting frame 2 is fixedly installed at the bottom of the tail rack body 1, and an adjustment component is arranged on the tail rack body 1.

[0022] The adjustment component includes a fixed block 9, which is fixedly installed on the front and rear side walls of the tail frame body 1. An installation cavity is opened inside the fixed block 9, and a spring 12 is installed inside the installation cavity. A movable block 13 is fixedly connected to one side of the spring 12, and a side of the movable block 13 away from the spring 12 is fixedly connected to a limiting column 15. The outside of the fixed block 9 is rotatably connected to a hollow column 8, and a plurality of equally spaced limiting grooves 16 are opened on the inner wall of the hollow column 8. One end of the limiting column 15 away from the movable block 13 passes through the fixed block 9 and is inserted into the inside of the limiting groove 16. The top of the hollow column 8 is fixedly connected to the backrest frame 6.

[0023] See also Figure 4 The backrest frame 6 is an "H"-shaped structure, a backrest cushion 7 is fixedly installed on one side of the backrest frame 6, both ends of the backrest frame 6 are respectively fixedly connected to the hollow column 8, a hollow rotating tube 17 is fixedly connected between the two backrest frames 6, and the hollow rotating tube 17 is rotatably connected to the inside of the tail frame body 1.

[0024] The comfort can be increased by providing the backrest cushion 7. When it is necessary to carry objects, the pull plate 11 is pulled to drive the movable block 13 to move downward, so that the spring 12 can be squeezed to make it expand and contract, so that the limiting column 15 is pulled out from the limiting groove 16, and the backrest frame 6 can be rotated to be located below the tail frame body 1, so as to avoid the backrest frame 6 blocking the space for carrying objects on the tail frame body 1. When the backrest frame 6 needs to be used, the backrest frame 6 can be rotated back to its original position and the limiting column 15 can be inserted into the limiting groove 16 to limit it, so that the backrest can be adjusted according to needs.

[0025] The arrangement of the backrest frame 6 and the backrest cushion 7 provides better protection or comfort for the children sitting on the backrest.

[0026] See also Figure 2 , Figure 3 A movable hole 10 communicating with the mounting cavity is formed on the side wall of the fixed block 9. A sliding rod 14 is fixedly connected to one side of the movable block 13. One end of the sliding rod 14 passes through the movable hole 10 and extends to the outside and is fixed with a pull plate 11.

[0027] After the limiting column 15 is pulled out from the limiting groove 16 by pulling the pull plate 11, the backrest frame 6 can be rotated to adjust the inclination angle, thereby facilitating adjustment according to usage requirements and improving applicability.

[0028] In this embodiment, reinforcing rods 3 are fixed to both the left and right sides of the connecting frame 2 , and one end of the reinforcing rod 3 is fixedly connected to the bottom of the tail frame body 1 .

[0029] The reinforcement rod 3 is provided to increase the stability between the tail frame body 1 and the connecting frame 2, thereby enhancing the bearing capacity of the tail frame.

[0030] In this embodiment, two mounting plates 4 are fixedly connected to the bottom of the tail frame body 1, and a plurality of mounting holes are opened inside the mounting plate 4. A connecting rod 5 is detachably mounted on the mounting plate 4 by bolts, and an assembly hole is opened on the side of the connecting rod 5 away from the mounting plate 4.

[0031] A round hole is formed at one end of the connecting frame 2 away from the tail frame body 1 , so that the tail frame can be easily installed on the bicycle frame by arranging the connecting frame 2 and the connecting rod 5 .

[0032] The working principle of the above embodiment is as follows: when it is necessary to carry objects, the pull plate 11 is pulled to drive the movable block 13 to move downward, so that the spring 12 can be squeezed to make it expand and contract, so that the limiting column 15 is pulled out from the limiting groove 16, and the backrest frame 6 can be rotated until the backrest frame 6 is flipped to be located below the tail frame body 1, so as to avoid the backrest frame 6 blocking the space for carrying objects on the tail frame body 1. When the backrest frame 6 needs to be used, the backrest frame 6 is rotated back to its original position through the operations in sequence, and the limiting column 15 can be inserted into the limiting groove 16 through the elasticity of the spring 12 itself to limit the hollow column 8, so that the backrest can be adjusted according to needs.
