Furthermore, an arrow is arranged on the one-way knob and vertically points to the traveling direction of the luggage case, the universal wheels are not stressed, and the resistance is increased to be locked when the instantaneous needle rotates to 360 degrees. According to the size of the luggage case and the different rated bearing, the magnet plate with proper size and proper strength can be selected and matched.
Furthermore, the upper conduit is a Y-shaped hollow tube, and the metal wire passes through the upper conduit and is divided into two paths which are respectively connected with the brake device at the bottom of the luggage case.
The utility model discloses can make the suitcase tire lock die to prevent that the suitcase from slideing wantonly, also can be according to the demand of the slope, thereby adjust knob and button increase or reduce the resistance and make the suitcase more controllable with the speed that the people moved the same, finally safe convenient passing through ramp again. An arrow mark is arranged on the 360-degree one-way resistance adjusting knob to prompt a user of the current stress condition of the tire.
(1) The utility model has the advantages that:
(2) the active controllable deceleration and locking functions of the universal wheel are realized;
(3) the magnet resistance is used, so that the loss caused by the traditional friction resistance adjustment is avoided, and the service life of the brake system is prolonged;
(4) the resistance is distributed evenly, the whole stress is stable, and no noise is generated in the working process;
(5) the mechanism has simple action, convenient operation and easy implementation and popularization.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples.
As shown in fig. 1 to 4, a brake device of a stepless speed change trunk capable of realizing self-locking comprises a button 1, a one-way knob 2, a metal wire 3, a lower conduit 4, a fixing screw 5, a pin 6, a universal wheel bearing 7, a magnet plate 8, a metal block 9, a hexagon screw 10, a support frame 11 and a universal wheel.
The fixing screw 5 is matched and fixed with the bottom of the luggage case, the pin 6 is arranged in the universal wheel bearing 7, the universal wheel bearing 7 is installed on the supporting frame 11 in an embedded mode and is responsible for steering of the universal wheel at various angles, and the hexagon screw 10 penetrates through the supporting frame 11 and the universal wheel to fix the universal wheel and the supporting frame.
The lower conduit 4 is fixed at the top of the support frame 11, one end of the magnet plate 8 is fixed at the inner side of the support frame 11 and is connected with the metal wire 3, and the magnet plate 8 is positioned above the universal wheel.
The metal wire 3 is stably controlled by the magnet plate 8 to shrink after the angle is adjusted through the lower conduit 4, and the metal block 9 is embedded into the universal wheel. The unidirectional knob 2 is indicated by an arrow and vertically points to the travelling direction of the luggage case, the universal wheels are not stressed, and the resistance is increased to be locked when the instantaneous needle rotates to 360 degrees. According to the size of the luggage case and the different rated bearing, the magnet plate 8 with proper size and strength can be selected and matched. The upper conduit 13 is a Y-shaped hollow pipe, and the metal wire 3 passes through the upper conduit 13 and is divided into two paths which are respectively connected with a brake device at the bottom of the luggage case.
When the mechanism works, an operator rotates the one-way knob 2 to recover the metal wire 3, the metal wire 3 is guided by the upper conduit 13 and then is stably coiled into the one-way knob 2, and therefore the magnet plate 8 is pulled, and the magnet plate 8 is close to the metal block 9 to generate magnetic resistance. The operator continues to rotate the one-way knob 2, and when the rotation angle reaches 360 degrees, the tires are locked, and the luggage case is stationary.
When the magnetic resistance recovery device is recovered, an operator lightly presses the button 1, the buckle in the one-way knob 2 is bounced off, the metal wire 3 starts to be released slowly, the metal wire 3 is guided by the lower conduit 4, then the distance between the magnet plate 8 and the metal block 9 is recovered stably, and the magnetic resistance is reduced until the magnetic resistance disappears.
