DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings: Example 1

[0019] See also Figure 1-4In the present embodiment, a paired wheel set for a baby stroller includes a square frame 1 and a partition 4. The inner wall of the square frame 1 is fixedly connected to the outer wall of the partition 4. The front and rear sides of the partition 4 are respectively connected with mounting structures 2. The outer side of the mounting structure 2 is connected with a cross plate 5, and the cross plate 5 is a rubber plate. The bottom of the square frame 1 is connected with a moving structure 3. A baby stroller connecting frame 6 is provided above the square frame 1. The front and rear sides of the baby stroller connecting frame 6 are respectively processed with notches 7.

[0020] The mounting structure 2 includes a straight rod 201 and a square plate 202. The inner sides of the two straight rods 201 are respectively fixedly connected to the front and rear sides of the partition 4. The outer wall of the straight rod 201 is slidably engaged with the inner wall of the square plate 202. The square plate 202 is subjected to force and slides forward and backward through the outer wall of the straight rod 201. An inclined block 203 is fixedly connected to the outer top of the square plate 202. The outer wall of the straight rod 201 is sleeved with a spring 204. The two ends of the spring 204 are respectively fixedly connected to the outer wall of the partition 4 and the inner side of the square plate 202. After the square plate 202 is forced to move inward, it rebounds by the elastic force of the spring 204. The outer wall of the square plate 202 fits the inner wall of the square frame 1, and the lower outer side of the square plate 202 is fixedly connected to the inner wall of the horizontal plate 5.

[0021] When the inclined block 203 in the mounting structure 2 contacts the bottom of the stroller connecting frame 6, it moves inward, and the moving inclined block 203 moves the square plate 202 inward, and at the same time the spring 204 is compressed. When the inclined block 203 moves to the position of the notch 7, the spring 204 loses pressure to provide a rebound force, so that the square plate 202 moves outward on the outer wall of the straight rod 201, and then moves the inclined block 203 outward, so that the inclined block 203 is inserted into the notch 7, and the paired installation is completed. The cross plate 5 is pressed inwardly to make the square plate 202 move inward on the inner wall of the straight rod 201, and then the inclined block 203 moves inward and disengages from the notch 7, and then the square frame 1 is pulled downward to complete the disassembly, thereby realizing the split installation, reducing the replacement cost of the paired wheel set, and eliminating the limitation of use.

[0022] The mobile structure 3 includes a vertical pole 301 and a round rod 302. The top of the outer wall of the vertical pole 301 is rotatably connected to the bottom of the square frame 1. The vertical pole 301 is rotated by the bearing at the bottom of the square frame 1. The bottom of the vertical pole 301 is fixedly connected to the top of the round rod 302. The front and rear ends of the outer wall of the round rod 302 are rotatably connected with rollers 303 respectively. The rollers 303 are rotated by the bearings at the ends of the outer wall of the round rod 302. Both rollers 303 are located below the square frame 1.

[0023] Working principle:

[0024] Disassembly and assembly of paired wheels for baby strollers:

[0025] The outer wall of the square frame 1 is plugged into the inner wall of the stroller connecting frame 6. When the inclined block 203 contacts the bottom of the stroller connecting frame 6, it moves inward. The moving inclined block 203 moves the square plate 202 inward. At the same time, the spring 204 is compressed. When the inclined block 203 moves to the position of the notch 7, the spring 204 loses pressure and provides a rebound force, so that the square plate 202 moves outward on the outer wall of the straight rod 201, and then moves the inclined block 203 outward, so that the inclined block 203 is inserted into the notch 7 to complete the paired installation. The cross plate 5 is pressed inward to make the square plate 202 move inward on the inner wall of the straight rod 201, and then the inclined block 203 moves inward to disengage from the notch 7, and then the square frame 1 is pulled downward to complete the disassembly.

[0026] The matching wheel set of the stroller is used for:

[0027] When the baby stroller connecting frame and the roller 303 are installed, the roller 303 contacts the ground, and the roller 303 rotates through the bearing at the end of the outer wall of the round rod 302, so that the baby stroller can move as a whole. At the same time, the vertical rod 301 can rotate at the bottom of the square frame 1 to adjust the overall angle of the roller 303. Example 2

[0028] See also Figure 1-4 : In this embodiment, a paired wheel set for a baby stroller also includes a top plate 8, the bottom of the top plate 8 is fixedly connected to the top of the square frame 1, and the top of the top plate 8 is in contact with the top of the inner wall of the baby stroller connecting frame 6.

[0029] Working principle:

[0030] After the square frame 1 is plugged into the baby stroller connecting frame 6, the top of the top plate 8 will fit with the top of the inner wall of the baby stroller connecting frame 6, and the top plate 8 supports the square frame 1 with its own rubber material to ensure the stable connection of the square frame 1.
