[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 4A knee stroller with an adjustable leg pad includes a frame 10 and a leg pad 20. The frame 10 is provided with a mounting rod 30, and the mounting rod 30 is provided with a sliding adjustment assembly 40. The leg pad 20 is mounted on the sliding adjustment assembly 40 and can move forward and backward relative to the mounting rod 30 following the sliding adjustment assembly 40. The utility model can adjust the leg pad according to different usage requirements through the front and back movable adjustment, so as to meet the needs of users of different body shapes, meet user needs, and improve user comfort.

[0024] See also Figure 4 , the sliding adjustment assembly 40 includes a base plate 410 fixedly mounted on the mounting rod 30 and a sliding seat 420 fixedly mounted on the leg pad 20;

[0025] The base plate 410 is provided with a sliding adjustment groove 411 , and a plurality of downwardly recessed locking grooves 412 are arranged along the sliding adjustment groove 411 on the upper surface of the base plate 410 ;

[0026] The sliding seat 420 is provided with a through slot 421 extending from front to back, and the base plate 410 is movably inserted into the through slot 421 ;

[0027] A sink hole 423 is provided on the sliding seat 420 below the through slot 421 , and the sink hole 423 is communicated with the through slot 421 ;

[0028] A clearance hole 422 is provided on the sliding seat 420 above the through slot 421 , and the clearance hole 422 is communicated with the through slot 421 ;

[0029] A bolt 430 is passed through the countersunk hole 423 , the bolt head of the bolt 430 is located in the countersunk hole 423 , and the stud of the bolt 430 passes through the countersunk hole 423 and the sliding adjustment slot 411 in sequence and extends into the through slot 421 ;

[0030] The end of the bolt 430 away from the bolt head is connected to the limiting nut 450, and the limiting nut 450 is inserted into any locking groove 412;

[0031] A spring 440 is disposed in the countersunk hole 423 . One end of the spring 440 abuts against the upper end surface of the bolt head, and the other end abuts against the hole wall of the countersunk hole 423 .

[0032] See also Figure 4 Under the action of the spring 440 , it can apply a downward force to the bolt 430 so that the limiting nut 450 connected to the bolt 430 remains inserted in the locking groove 412 .

[0033] To adjust the front-to-back position of the leg pad 20, the bolt head 430 is pressed, causing the bolt 430 to move upward. This upward movement of the bolt 430 drives the retaining nut 450 upward, disengaging the retaining nut 450 from the locking groove 412, thereby unlocking the leg pad 20. In the unlocked state, the leg pad 20, the sliding seat 420, the bolt 430, and the retaining nut 450 can move forward and backward relative to the base plate 410.

[0034] See also Figure 3 The sliding seats 420 are provided with two and are spaced apart from each other.

[0035] See also Figures 1 to 3 A plurality of wheels 110 are mounted on the vehicle frame 10 .

[0036] See also Figures 1 to 3 A handle 120 is installed on the front side of the frame 10.
