The braking device based on the universal roller of the four-wheel suitcase, the braking device includes a pulling part and a braking part, and the pulling part is connected to the braking part through a traction device; the pulling part is connected to the trunk , and the pulling part includes a guide rod, a telescopic button arranged on the guide rod and a slider with a hole slidably connected to the guide rod, and a positioning mechanism is also provided on the guide rod; The brake component is connected to the protective shell of the universal roller of the suitcase, and the brake component includes a bent fixed connection block and a brake plug hingedly connected to the fixed connection block.

Specifically, when it is to be fixed, the slider with holes is pulled onto the retractable button so that it just snaps into the hole of the slider with holes, and the steel wire is pulled so that the brake plug of the brake component is inserted into the universal roller to realize universal locking. To fix the roller, the brake plug of the brake component is installed above the universal roller.

Preferably, the fixed connection block is divided into a horizontal connection part and an inclined guide part, and the angle between the horizontal connection part and the inclined guide part is 120-150°.

Preferably, a turning slot is formed at the bottom end of the inclined guide part, and the tail of the brake plug is hingedly connected in the turning slot through a hinge shaft.

Preferably, the front end of the brake plug is a wedge-shaped structure.

Preferably, the pulling device is a steel wire, and the top end of the steel wire is fixedly connected to the perforated slider.

Preferably, the aperture of the slider with holes is slightly larger than the outer diameter of the retractable button.

Preferably, the positioning mechanism includes an upper positioning plate and a lower positioning plate, both of which are located at the upper and lower ends of the guide rod.

Preferably, a return spring is further provided between the upper positioning plate and the perforated slider.

The beneficial effects of the utility model are: the utility model solves the problem that the rollers of the four-wheeled suitcase in the prior art do not have a braking device through the combination of the pulling part and the braking part, and there are no braking devices on traffic facilities such as buses, trains, and subways. The phenomenon that the suitcase moves casually, and the structure adopted by the utility model is simple, easy to use, brakes in time, saves time and effort, can quickly realize the fixing of the universal roller, and has strong practicability.

detailed description

In order to enable those skilled in the art to better understand the technical solution of the utility model, the technical solution of the utility model will be further described below in conjunction with the drawings and embodiments.

With reference to a kind of braking device based on four-wheel suitcase universal roller 7 shown in accompanying drawing 1, this braking device comprises pulling part and braking part, between described pulling part and described braking part through traction device connection; the pulling part is connected to the luggage case, and the pulling part includes a guide rod, a retractable button 2 arranged on the guide rod, and a sliding block 1 with holes slidably connected to the guide rod. The guide rod is also provided with a positioning mechanism; the braking component is connected to the protective shell of the suitcase universal roller 7, and the braking component includes a bent fixed connection block 4 and is hingedly connected to the The brake plug 6 on the fixed connection block 4, the aperture of the perforated slider 1 is slightly larger than the outer diameter of the telescopic button 2, the traction device is a steel wire 3, and the top of the steel wire 3 is fixedly connected to the On the perforated slider 1.

Further, the fixed connection block 4 is divided into a horizontal connection part and an inclined guide part, the angle between the horizontal connection part and the inclined guide part is 120-150°, and at the bottom end of the inclined guide part There is a turning slot, the tail of the braking plug 6 is hingedly connected in the turning slot through the hinge shaft 5, and the front end of the braking plug 6 is a wedge-shaped structure.

Further, the positioning mechanism includes an upper positioning plate 8 and a lower positioning plate 9, the upper positioning plate 8 and the lower positioning plate 9 are located at the upper and lower ends of the guide rod, the upper positioning plate 8 is connected to the holed slide A back-moving spring is also arranged between the blocks 1, and the back-moving spring plays a buffering and auxiliary role for the up and down movement of the perforated slider 1, while the upper positioning plate 8 and the lower positioning plate 9 all play a role in moving up and down the perforated slider 1. To the limit function to prevent excessive up and down movement.

In the utility model, the braking device of the universal roller 7 of the four-wheel suitcase only needs to be installed on a wheel on the suitcase, and is divided into a pulling part and a braking part, and the starting pulling part makes the braking of the braking part The movable plug 6 is inserted in the roller to realize the fixing of the universal roller 7.

During specific use, when you want the suitcase not to move casually, move the perforated slider 1 upwards so that the retractable button 2 is stuck in the hole of the perforated slider 1, and the steel wire 3 is pulled, because the brake plug 6 is hinged. Driven by the shaft 5, it can move, so that the brake plug 6 is inserted into the universal roller 7, and the universal roller 7 is fixed. When you want the universal roller 7 to move, you only need to press the retractable button 2. The braking device can be restored to its original position.
