Description

forward push suitcase

technical field

The utility model belongs to a suitcase, in particular to a suitcase that can be pushed forward. The user can push the suitcase stably to ensure that the suitcase is within the sight of the user and prevent people from stealing the contents of the suitcase.

Background technique

Suitcases are often used for long-distance travel. In order to carry the suitcase conveniently, because the suitcase is not small in size and heavy after loading, it is difficult to move. Many suitcases are equipped with four rollers on the flat bottom of the box. In this way, the suitcase can move smoothly on the ground. In addition, a pull bar is arranged at the back of the suitcase, which can be used for the user to pull the suitcase. A scroll wheel is vacated.

In a poor security environment, passengers would want the suitcase to be within their line of sight to prevent unscrupulous people from stealing the contents of the suitcase. Two rollers are on the ground, and it is not easy to push the suitcase when only two rollers are on the ground.

Utility model content

According to the shortcomings of the existing suitcases that are not suitable for being pushed forward, the creator improves its deficiencies and deficiencies, and then creates a suitcase that can be pushed forward.

The main purpose of the utility model is to provide a suitcase that can be pushed forward, whereby the suitcase can be located in the sight of passengers to prevent people from stealing the contents of the suitcase. The center of gravity is stable, and the user only needs to apply forward force instead of upward or downward force.

For reaching above-mentioned purpose, the suitcase that the utility model can push forward comprises:

a box;

a base, which is set at the bottom of the box, and four rollers are set at the bottom of the base;

A tie rod assembly, which is arranged on the back of the cabinet, and includes two tie rod brackets, two tie rods and a pull handle. can protrude upwards, the pull handle is arranged on the top of the two pull rods; and

A tripod assembly is arranged on the back of the box and the pull rod assembly, and includes a tripod, two movable rollers, two rear connecting rods and two front connecting rods, and the upper ends of the tripods are respectively pivoted on the pull rod brackets , the movable rollers are rotatably pivoted at the bottom ends of the tripods respectively, and can roll, the rear ends of the rear connecting rods are respectively arranged at the bottom ends of the tripods, and the front ends of the front connecting rods are respectively They are pivotally arranged at the bottom ends of the pull rod brackets, and the rear ends are respectively pivotally arranged on the front ends of the rear connecting rods.

Wherein, the above-mentioned tripod assembly further includes a fixed ring, a cross bar and an actuating rod, the fixed ring is arranged on the back of the box body, and has a perforation, and the two ends of the cross bar are respectively pivoted on the corresponding rear connecting rods On the front end and the corresponding bottom end of the tripod, the bottom end of the actuating rod is pivoted with the cross bar, and the top is perforated through the fixing ring. A handle is provided on the top end of the actuating rod. Pushing down the handle can make the front , The rear connecting rod is unfolded to make the tripod extend backward.

The aforementioned tripod assembly further includes at least one C-shaped buckle, which is fixed on the back of the box body, and can buckle the crossbar when the tripod is folded, thereby positioning the tripod.

The aforementioned base is hollow, and a bracket protruding forward is provided in the front edge of the base, and a retaining edge protruding vertically upward is provided at the front end of the bracket.

With the above-mentioned technical means, when the front and rear connecting rods are unfolded into a flat shape, the tripod can be stretched back. At this time, the movable roller and the two rollers at the rear of the base are on the ground at the same time, so that the upper end of the box body is tilted backward, and the rod is pulled at the same time. It protrudes towards the rear obliquely, so that the user can hold the handle and push the suitcase forward, so that the user can easily push the suitcase and keep the suitcase in their sight, so as to prevent people from stealing the contents of the suitcase. In addition, When the suitcase is pushed, it leans backward and the center of gravity falls between the tripod assembly and the two rear rollers of the base stably. It will not lean forward or backward any further. Therefore, the user only needs to apply forward force instead of upward force. Or downward power to stabilize the suitcase, therefore, promote the suitcase of the utility model compared with pulling the traditional suitcase, labor saving reaches 90%.
