[0036] like Figures 1-10 As shown, in one embodiment of this utility model, a pedal-operated braking system is provided, including a limiting disc 10, a first mounting base 20, a limiting rod 30, a second mounting base 40, a brake arm 50, a locking assembly 60, a first reset member 70, and a second reset member 80. The limiting disc 10 is installed inside one of the traveling wheels 90, and the limiting disc 10 is arranged coaxially with the traveling wheel 90. A through hole 12 is provided at the center of the limiting disc 10 for a connecting shaft 100 to pass through, and the connecting shaft 100 is used to connect the two traveling wheels 90. The limiting disc 10 has multiple limiting holes 11, which are arranged in a circular array along the through hole 12. The first mounting base 20 is fixedly installed on the frame (not shown in the figure) and located inside the traveling wheel 90. The limiting rod 30 is telescopically fitted on the first mounting base 20, and the limiting rod 30 can be inserted into any of the limiting holes 11. The second mounting base 40 is fixedly mounted on the frame. The brake arm 50 is hinged to the second mounting base 40 and located on the side of the limit rod 30 away from the limit disc 10. The brake arm 50 is used to push the limit rod 30 toward the limit disc 10 during its rotation. A pedal 51 is installed at the end of the brake arm 50 away from the second mounting base 40.
[0037] The locking assembly 60 is used to lock the brake arm 50 after the brake arm 50 is stepped on and the limiting rod 30 is inserted into the limiting hole 11, so that the limiting rod 30 remains in the state of extending into the limiting hole 11, or the locking state of the brake arm 50 is released. The first reset member 70 is used to apply a elastic force to the limiting rod 30, so that the limiting rod 30 has a tendency to move and reset towards the brake arm 50. The second reset member 80 is used to apply a elastic force to the brake arm 50, so that the brake arm 50 has a tendency to rotate and reset upwards.
[0038] When the walking wheel 90 needs to be braked, the user steps down on the pedal 51, the brake arm 50 rotates around the second mounting seat 40, the brake arm 50 pushes the limiting rod 30 to move towards the limiting disc 10, and the limiting rod 30 is inserted into a limiting hole 11 on the limiting disc 10, thereby achieving the braking of the walking wheel 90. At the same time, the locking assembly 60 also locks the brake arm 50, so that the limiting rod 30 remains in the state of extending into the limiting hole 11.
[0039] When the walking wheel 90 needs to be unlocked, the user releases the locking of the brake arm 50, so that the second reset member 80 drives the brake arm 50 to rotate and reset upwards, and at the same time, the first reset member 70 also drives the limiting rod 30 to move towards the brake arm 50, so that the limiting rod 30 exits the limiting hole 11, thereby achieving the unlocking of the walking wheel 90.
[0040] The embodiment discloses a stepping type brake system, which drives the limiting rod 30 to cooperate with the limiting disc 10 by stepping on the brake arm 50, so as to limit the rotation of the walking wheel 90 to achieve braking. At the same time, the locking assembly 60 can lock the brake arm 50, so that the limiting rod 30 remains in the state of extending into the limiting hole 11, thereby maintaining the braking state of the walking wheel 90, eliminating the risk of brake failure of the conventional method relying on the friction of the tire surface, and improving the safety. After the locking assembly 60 releases the locking state of the brake arm 50, the first reset member 70 and the second reset member 80 drive the limiting rod 30 and the brake arm 50 to reset respectively, thereby facilitating subsequent use and improving the convenience of operation.
[0041] In one embodiment, the locking assembly 60 comprises a locking block 61, a connecting arm 62 and a guide pin 63. The locking block 61 is arranged on the brake arm 50, and the locking block 61 is provided with a first groove 611, a second groove 612, a third groove 613 and a fourth groove 614 in sequence from the side away from the limiting rod 30, the fourth groove 614 is in communication with the first groove 611 at the end away from the third groove 613, the second groove 612 and the third groove 613 form a "V" shape structure, and a limiting portion 615 is formed at the corner of the second groove 612 and the third groove 613. The connecting arm 62 is hinged on the first mounting seat 20, and the guide pin 63 is arranged on the connecting arm 62, the guide pin 63 can slide along the first groove 611 and the second groove 612 to the limiting portion 615, and can be temporarily positioned in the limiting portion 615, and the guide pin 63 can slide along the third groove 613 and the fourth groove 614 in sequence to the first groove 611 after leaving the limiting portion 615.
[0042] After stepping on the pedal 51, the locking block 61 will rotate synchronously with the brake arm 50, and in this process, the guide pin 63 on the connecting arm 62 will slide along the first groove 611, the second groove 612 and the third groove 613 under the action of the groove walls of the first groove 611, the second groove 612 and the third groove 613, and when the guide pin 63 is positioned in the limiting portion 615, the brake arm 50 and the locking block 61 will have a tendency to reset upward under the elastic force of the second reset member 80, and the guide pin 63 will block the reset of the locking block 61 and the brake arm 50, so that the brake arm 50 cannot rotate upward, thereby realizing the locking of the brake arm 50.
[0043] When it is necessary to unlock the walking wheel 90, the user steps on the pedal 51 once (and releases the pedal 51 after stepping on), the locking block 61 will rotate downward synchronously with the brake arm 50, and under the elastic force of the second reset member 80, the brake arm 50 and the locking block 61 will have a tendency to reset upward, and the guide pin 63 will leave the limiting portion 615 and slide into the fourth groove 614, and under the action of the groove wall of the fourth groove 614, the guide pin 63 will slide into the first groove 611 again. In this process, the second reset member 80 will continue to drive the brake arm 50 to reset upward, and at the same time, the first reset member 70 will also drive the limiting rod 30 to move towards the brake arm 50, so that the limiting rod 30 exits the limiting hole 11, thereby realizing the unlocking of the walking wheel 90.
[0044] The structure design of the locking assembly 60 is convenient to realize the locking or unlocking operation of the brake arm 50, the operation is convenient, and the overall structure is compact and ingenious.
[0045] In one embodiment, the first mounting base 20 is provided with a first side plate 21 located at the side of the connecting arm 62 away from the lock block 61, and the first side plate 21 is provided with a connecting bolt 64, and the connecting arm 62 is threadedly connected to the connecting bolt 64. By using the connecting bolt 64 to mount the connecting arm 62 on the first side plate 21, when the guide pin 63 slides along the first slot 611, the second slot 612, the third slot 613 or the fourth slot 614, the connecting arm 62 will also swing adaptively, so that the guide pin 63 can limit the lock block 61.
[0046] In one embodiment, the brake arm 50 is provided with a push block 52 on the side facing the limiting rod 30, the push block 52 is provided with an inclined surface 521, the upper end of the inclined surface 521 is inclined towards the limiting disc 10, and the limiting rod 30 abuts against the inclined surface 521. The limiting rod 30 is provided with a ball head 31 abutting against the inclined surface 521. After the brake arm 50 is stepped on, the inclined surface 521 on the push block 52 cooperates with the ball head 31 of the limiting rod 30, so as to push the limiting rod 30 to move towards the limiting disc 10.
[0047] In one embodiment, the first mounting base 20 is provided with a second side plate 22 and a support plate 23, the second side plate 22 is located between the limiting disc 10 and the support plate 23, and the limiting rod 30 is movably arranged through the second side plate 22 and the support plate 23.

The limiting rod 30 is fixedly provided with a second limiting pin 33 located outside the second side plate 22.
[0048] After the push block 52 pushes the limiting rod 30 to move towards the limiting disc 10, the first limiting pin 32 cooperates with the second side plate 22 to compress the first return member 70. When the brake arm 50 is turned upwards, the first return member 70 pushes the first limiting pin 32, so that the limiting rod 30 automatically exits the limiting hole 11, thereby realizing the resetting of the limiting rod 30.
