Anti-emergency brake draw-bar box

Abstract

The invention discloses an anti-emergency brake draw-bar box. The anti-emergency brake draw-bar box comprise a box body, and a bottom flexible transmission plate attached to the ground of the box bodyis fixedly arranged on the ground the of the box body; the bottom flexible transmission plate is connected with a pneumatic base which is used in matching with the bottom flexible transmission plate;four walking wheels are arranged at the bottom end of the pneumatic base, and communicate with a pneumatic power source of the pneumatic base through a connecting pipe; and when relative displacementoccurs between the bottom flexible transmission plate and the pneumatic base under the action of inertia, one or more travelling wheels can be braked when the relative displacement occurs. Accordingto the anti-emergency brake draw-bar box, automatic braking type design is adopted, no limited energy such as electric power needs to drive, when a vehicle brakes suddenly, the upper box body has great inertia under the action of the inertia, thus the box body continues to move under the action of the inertia, and further drives a brake block to extend out of a containing chamber through the pneumatic base, at this time, the brake block abuts against the ground, the role of braking is effectively achieved, and the convenient wheels are prevented from rolling forward and causing safety hazards.

Description

technical field [0001] The invention relates to the technical field of interior decoration, in particular to an anti-emergency brake trolley case. Background technique [0002] With the continuous development of society, trolley cases are often used to carry daily necessities when traveling, which brings great convenience to travel and business trips. But correspondingly, there are also many inconveniences in the trolley case. For example, in a common car, when the driver steps on the sudden brake, the trolley case will continue to move forward under the action of inertia. Running to the driver will affect the driver's driving. On the other hand, it is easy to cause damage to the trolley case and its contents, so it is urgent to change. Contents of the invention [0003] The object of the present invention is in order to solve above-mentioned problem, and the anti-emergency brake trolley box that proposes. [0004] In order to achieve the above object, the present invent...
