[0009] The bottom of the pull rod is provided with a brake assembly.

[0010] The brake assembly comprises a horizontal rod fixedly installed on the bottom surface of the pull rod, a U-shaped plate fixedly installed on the bottom surface of the horizontal rod, a brake plate fixedly installed on the bottom surface of the U-shaped plate, and a fixing plate fixedly installed on the side wall of the box body and arranged on the left and right sides of the U-shaped plate.

[0011] Preferably, the bottom surface of the limiting rod is fixedly installed with a limiting disc, so that the limiting rod is prevented from being separated from the fixing plate.

[0012] Preferably, the arc-shaped plate is in a circular arc shape, and the inner wall of the arc-shaped plate is provided with evenly distributed anti-skid grooves, so as to increase the contact area between the arc-shaped plate and the arc surface of the roller, increase the friction between the arc-shaped plate and the roller, and provide better braking effect.

[0013] Preferably, the top surface of the brake plate is provided with evenly distributed anti-skid holes, and the bottom surface of the brake plate is bonded with an anti-skid pad, so that the brake plate is in contact with the ground, and the user can step on the top surface of the brake plate to limit the box body.

[0014] Preferably, the anti-skid pad is made of rubber material, and the bottom surface of the anti-skid pad is provided with anti-skid lines, so that the rubber material is skid-resistant and wear-resistant, and has a long service life.

[0015] The utility model provides a kind of box bag pull rod with one-way limiting and automatic braking function.It has the following beneficial effects:

[0016] This luggage handle with one-way limiting and automatic braking function limits the luggage by pushing the handle downwards so that the anti-slip pad contacts the ground. During this process, the horizontal bar pushes the top plate and the limiting rod, vertical plate and curved plate below it downwards until the curved plate contacts the curved surface of the roller, thus braking the roller. Stepping on the top surface of the brake plate can prevent the luggage from tipping over, avoiding the need to hold the luggage by hand. It is simple and convenient to use. Moreover, the anti-slip pad and the curved plate limit the luggage simultaneously, resulting in better braking effect. It solves the problem that the existing device only brakes the roller by limiting the curved plate, which has poor braking effect and requires holding the luggage by hand to prevent it from tipping over, making it more troublesome to use.
