DETAILED DESCRIPTION

[0021] The preferred embodiments of the present application will be described in detail below with reference to the drawings.

[0022] As Figures 1-4 shown, a pull rod with brake cable, comprising operation bin 2, operation bin 2 is connected to pull rod assembly 1, the bottom surface of operation bin 2 is connected with first limiter 3, two adjusters 4 are connected in operation bin 2, brake cable tube 5 is connected to first limiter 3, brake cable 501 is arranged in brake cable tube 5, one end of brake cable 501 is connected with adjuster 4, the other end of brake cable 501 is provided with universal wheel 6, gear 7 is rotatably arranged in operation bin 2, traction rod 8 is hinged to gear 7, pull line clamp 201 is slidably arranged in operation bin 2, one end of pull line clamp 201 is connected with brake cable 501, brake return spring 11 is sleeved at one end of brake cable 501, brake return spring 11 is located between adjuster 4 and pull line clamp 201. The top surface of operation bin 2 is slidably provided with limiting plate 12, the bottom surface of limiting plate 12 is connected with rack 1201, rack 1201 is engaged with gear 7, the top end of rack 1201 has a rubber layer, the rubber layer is attached to the inner top surface of operation bin 2. Swing frame 9 is hinged to universal wheel 6, limiting column 10 is connected to the two sides of swing frame 9 respectively, limiting teeth 101 are connected to the inner wall of universal wheel 6 respectively, limiting column 10 is clamped with limiting teeth 101

[0023] In use, when the limiting plate 12 is pushed to the right, the rack 1201 drives the gear 7 to rotate clockwise by one hundred and eighty degrees, at this time, the hinge of the traction rod 8 and the gear 7 will be located at the highest point of the gear 7, because the top end of the rack 1201 has a rubber layer, the damping force of the rack 1201 can be increased, the rack 1201 is limited to the gear 7, to ensure that the gear 7 is in a locked state;

[0024] By pulling the traction rod 8, the pull line clamp 201 can pull the brake cable 501 to move upwards, and the extrusion of the pull line clamp 201 will make the brake return spring 11 in a compressed state.

[0025] When the brake line 501 is pulled, the die-casting ball head on the brake line 501 of the swing frame 9 drives one end of the swing frame 9 to be raised upward, and the other end of the swing frame 9 drives the limiting column 10 to move downward until the limiting column 10 is clamped into the limiting tooth 101, thereby completing the locking work of the universal wheel 6.

[0026] Through the brake system integrated on the pull rod assembly 1, the user can easily realize the braking of the luggage without bending over or squatting, greatly improving the convenience of use. At the same time, it avoids the misoperation caused by inconvenient operation or blocked view in public places, and improves the fluency and safety of use.

[0027] When it is necessary to unlock the universal wheel 6, the user pushes the limiting plate 12 to the left, and the gear rack 1201 drives the gear 7 to rotate counterclockwise by one hundred and eighty degrees. At this time, the elastic force of the brake return spring 11 can drive the traction rod 8, the pull line clamp 201, the swing frame 9 and the limiting column 10 to reset, thereby completing the unlocking of the universal wheel 6.

[0028] As shown in Figure 3 and Figure 4 , the limiting spring 14 is arranged on the universal wheel 6, the other end of the brake line 501 has a die-casting ball head, the swing frame 9 is connected to the other end of the brake line 501 through the die-casting ball head, and the limiting spring 14 applies an elastic force to the die-casting ball head.

[0029] In use, the elastic force applied to the die-casting ball head by the limiting spring 14 prevents the die-casting ball head from falling off the swing frame 9, ensuring the stability of the brake line 501.

[0030] As shown in Figure 3 and Figure 4 , the connecting plate 15 is connected to the universal wheel 6, the connecting plate 15 is connected to the luggage, the second limiting device 16 is connected to the connecting plate 15, and the other end of the brake line pipe 5 is connected to the second limiting device 16.

[0031] In use, the connecting plate 15 is used to fix the luggage, so that the universal wheel 6 can be connected to the luggage. When the brake line 501 is pulled, the brake line pipe 5 can maintain a stable position due to the fixing effect of the first limiting device 3 and the second limiting device 16, avoiding shaking or deviation caused by external force. The stability and reliability of the luggage brake are improved.

[0032] As shown in Figure 1 , Figure 3 and Figure 4 , the decorative cover plate 13 is connected to the pull rod assembly 1, the operation bin 2 is connected to the decorative cover plate 13, and the decorative cover plate 13 is embedded in the luggage.

[0033] In the device, the entire brake system can be hidden by the decorative cover plate 13, and the brake system is hidden at the mounting position of the drawbar assembly 1. In this way, the appearance of the luggage case is not changed, and the operation function of the drawbar assembly 1 is not affected.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
