Description

Retractable stationary stand with brake function for case or bag or bag

【Technical field】

The invention relates to a retractable stationary frame with braking function for boxes or bags or bags.

【Background technique】

According to market research, the structures of existing cases and bags (comprising trolley cases, wheeled suitcases, wheeled luggage bags or bags, etc.) are all provided with movable wheels at the bottom of the accommodating body. , airplanes, high-speed rail, etc.) when using, it is often encountered that the containing body moves with the force of its inertia, and collisions occur from time to time, which may damage the contents of the box and increase unsafe factors.

According to patent retrieval, in order to solve the above problems, a Chinese invention patent application has appeared, the application number is (CN201410296162.4), which discloses a button-controlled brake device for trolley luggage, including a first spring, a chute seat, a push button , Handbrake cable, retractable rod, first slider, first linkage lever, second linkage lever, second slider, second fixing seat, first fixing seat, rivet, first roller, second roller, button hole , button, second spring, brake structure, etc. The button-controlled brake device of the trolley case of the present invention is a button-controlled brake device that is easy to refit and does not affect the overall layout of the case, so that the refitted case can be pressed in time. The button is used for braking, and the brake device can be automatically activated when the pull rod is retracted and parked to prevent the luggage from slipping after parking.

However, its complex structure, high processing difficulty, high process cost and material cost are not suitable for mass production enterprises, and the more complex the structure, the worse the quality stability, and the rework problem during processing often plagues production enterprises. And the brake device is also inconvenient to use.

Another example is the Chinese invention patent application (CN201220113480.9), which discloses a trolley case with a brake device, which includes a housing body, a roller is provided under the housing body, and a brake device is provided on one side of the roller , the brake device is provided with a brake button. The invention solves the problem in the prior art that there is no trolley case that can make the wheels of the trolley case unable to rotate, so that the trolley case can be fixed and placed more stably, and the controllability of the rollers is realized by setting a brake device.

But its braking structure and principle are to limit the roller to brake. This structure is easy to damage and not durable for long-term use. Because the friction of the roller itself is small, the phenomenon of unstable braking often occurs.

In order to overcome the above-mentioned problems, we have developed a kind of retractable stationary frame with braking function for case or bag or bag.
