Movable large-scale turnover box with stop device

Abstract

The invention discloses a movable large-scale turnover box with a stop device. The large-scale turnover box comprises side plates, a base, protective legs and wheels, wherein the large-scale turnover box further comprises the detachable stop device which is mounted on the base. The stop device comprises a mounting seat, a control device and a support seat which can be in contact with the ground. The mounting seat is detachably mounted on the base of the turnover box and is in telescopic connection with the support seat. The control device is used for controlling the support seat to extend or retract so as to enable the support seat to be in contact with or be separated from the ground. The stop device in the movable large-scale turnover box disclosed by the invention has the advantages of simple structure, simplicity in operation, long service life, convenience in replacement and low maintenance cost.

Description

technical field [0001] The invention relates to a container, in particular to a large turnover box. Background technique [0002] In some existing large-scale turnover boxes, in order to move easily, a mobile device is installed at the bottom of the turnover box. The mobile device mainly consists of four wheels, such as the turnover box disclosed in European Patent EP1524170A2. In this way, when the turnover box needs to be moved, only a relatively small force is needed to push the turnover box to realize the movement of the turnover box. [0003] However, after the turnover box is equipped with a moving device such as wheels, if the operator leaves during its use, the turnover box may move by itself when it is touched by a slope or accidentally, which will be dangerous, such as moving by itself. It will collide with obstacles, causing damage to items, etc. [0004] In order to solve this problem, some documents propose that a stop device is provided in a turnover box prov...

Problems solved by technology

[0005] However, the stopping device disclosed in US20100187782A1 has the following disadvantages: (1) The linkage lever inside the base is manipulated by the pedal, and the transmission distance is relatively long, resulting in a reduction in the effectiveness of the lever force after transmission, and it is difficult for the pedal to control the base The expansion and contraction of the lifting or stopping device has low reliability, and one pedal controls multiple surfaces in contact with the ground on the stopper. Only by raising or lowering the base or the stopper evenly as a whole can the stop effect be achieved, which is inconvenient to use and has a complicated structure; (2), if the stop is in the unlocked state (that is, when the stopper is off the ground and the wheels support the base) When the bases are stacked, the base stacked on it will move when it is tilted, so the stop device must be in the working state (that is, the stop device touches the ground) before the base is stacked, which is inconvenient to use; (3), The material of the stopper and its base is the same, and it is a rigid friction with the ground, the friction coefficient is small, and the stop effect is not good; (4), the stopper is not easy to replace after damage, and the manufacturing cost and maintenance cost are high
