DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] See attached Figure 1-7 : In the present embodiment, a calf-supporting one-handed adjustment structure of a baby stroller comprises a first support arm 1 and a transmission rod 10. The first support arms 1 on both sides are rotatably connected to the protruding part of the surface of the transmission rod 10 through a slideway provided on the surface. One end of the transmission rod 10 passes through the surface of the first support arm 1. An adjustment device 2 is provided on the surface of the first support arm 1 on one side. A locking device 8 is provided on the surface of the first support arm 1 on one side. One end of the first support arms 1 on both sides are fixedly connected to the surface of the armrest 4. A rubber sleeve 9 is fixedly connected to the surface of the armrest 4. The rubber sleeve 9 can prevent slipping when the operator pushes. The surface of the transmission rod 10 is symmetrically fixedly connected to the second support arm 6. The transmission rod 10 can support the second support arms 6 on both sides to move synchronously. The surfaces of the first support arms 1 on both sides are rotatably connected to the first rotating rod 12 through bearings. The first rotating rods 12 on both sides can install the first wheels 5. The first support arm 1 is a larger leg of the vehicle, and the second support arm 6 is a smaller leg of the vehicle.

[0023] One end of the first rotating rod 12 on both sides is fixedly connected to the first wheel 5, the surfaces of the second support arms 6 on both sides are rotatably connected to the second rotating rod 11 through bearings, one end of the second rotating rod 11 on both sides is fixedly connected to the second wheel 7, and the second rotating rods 11 on both sides can be used to install the second wheel 7, the surfaces of the first support arms 1 on both sides are fixedly connected to the surface of the seat 3, a groove is provided on the surface of the second support arm 6 on one side, the groove on the surface of the disc support arm 6 can be clamped with one end of the straight rod 802, one end of the straight rod 802 passes through the surface of the first support arm 1 through the through hole provided on the surface of the first support arm 1 on one side, and the surface of the straight rod 802 is slidably connected to the through hole provided on the surface of the first support arm 1.

[0024] See attached Figure 1-7The adjusting device 2 includes a first shell 201 and a pull rod 203. The first shell 201 is fixedly connected to the surface of the first support arm 1. The first shell 201 is slidably connected to the surface of the pull rod 203 through a slideway opened on the surface, fixing the motion track of the pull rod 203. The surface of the pull rod 203 is symmetrically fixedly connected with sliders 205. The surfaces of the sliders 205 on both sides are slidably engaged with the slideways opened on the surface of the first shell 201. The sliders 205 on both sides can be engaged with the slideways on the surface of the first shell 201, so that the pull rod 203 cannot rotate. One end of the pull rod 203 passes through the surface of the first shell 201 and is fixedly connected to the surface of the circular plate 207. The surface of the circular plate 207 is symmetrically fixedly connected with plug rods 208. The plug rods 208 on both sides can be engaged with the slideways on the surface of the first shell 201. The angle of the transmission rod 10 is fixed by clamping with multiple groups of grooves at one end of the transmission rod 10. The surface of the circular plate 207 and the inner surface of the first shell 201 are respectively fixedly connected to the two ends of the first spring 206. The elastic coefficient of the first spring 206 can meet the working needs according to actual needs. The first spring 206 can make the circular plate 207 return to its original position. The surface of the circular plate 207 is tightly pressed against the surface of the threaded rod 204. The threaded rod 204 is threadedly connected to the threaded hole opened on the surface of the first shell 201. The threaded rod 204 can move in the first shell 201 by rotating. One end of the threaded rod 204 passes through the surface of the first shell 201 and is fixedly connected to the round block 202. The threaded rod 204 can be easily rotated through the round block 202.

[0025] See attached Figure 1-7 : The locking device 8 includes a second shell 801 and a straight rod 802. The second shell 801 is fixedly connected to the surface of the first support arm 1 on one side. The second shell 801 is slidably connected to the surface of the straight rod 802 through a slideway opened on the surface, fixing the motion track of the straight rod 802. The surface of the straight rod 802 is symmetrically fixedly connected with a clamping block 803. After the clamping blocks 803 on both sides are rotated to a certain angle, they can no longer be clamped with the slideway on the inner surface of the second shell 801, so that the straight rod 801 can move. The surfaces of the clamping blocks 803 on both sides are slidably clamped with the slideway opened on the inner surface of the second shell 801. The surface of the straight rod 802 is fixedly connected with a fixing plate 804. The surface of the fixing plate 804 and the inner surface of the second shell 801 are respectively fixedly connected to the two ends of the second spring 805. The second spring 805 can meet the working needs according to actual needs. The second spring 805 can pull the straight rod 802 to move.

[0026] Working principle:

[0027] When you need to adjust the stroller's lower leg:

[0028] Adjustment process:

[0029] The operator rotates the threaded rod 204 through the round block 202 so that the threaded rod 204 no longer presses against the surface of the circular plate 207. The operator pulls the circular plate 207 through the pull rod 203 for synchronous movement, so that the circular plate 207 can compress the first spring 206 while making the insertion rods 208 on both sides no longer engage with the multiple groups of grooves at one end of the transmission rod 10. The operator pulls the pull rod 203 upward so that the second support arms 6 on both sides can rotate toward the first support arm 1 under the action of gravity. The operator presses the pull rod 203 downward so that the second support arms 6 on both sides can rotate away from the first support arm 1, so that the operator can adjust the second support arms 6 on both sides with one hand. According to the above operation, the pull rod 203 is released, and the insertion rods 208 on both sides can be engaged with the grooves at one end of the transmission rod 10 again under the push of the first spring 206. The threaded rod 204 can be rotated back to its original position to fix the positions of the insertion rods 208 on both sides.

[0030] Folding process:

[0031] When no longer in use, according to the above operation, the second support arms 6 on both sides are rotated toward the first support arm 1, so that the second support arms 6 on both sides overlap with the first support arm 1, and the operator rotates the straight rod 802 so that the straight rod 802 can drive the clamping blocks 803 on both sides to move synchronously, so that the clamping blocks 803 on both sides slide in the slideway on the inner surface of the second shell 801, but after the clamping blocks 803 on both sides are rotated to the extreme position, the straight rod 802 can be pulled quickly by the fixing plate 804 under the pull of the second spring 805, so that the straight rod 802 can pass through the grooves on the surface of the first support arm 1 and the surface of the second support arm 6 to clamp, so that the angles of the second support arms 6 on both sides are fixed, and the folding operation is completed.

[0032] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
