Description

Suitcase coupling

The invention relates to a suitcase coupling capable of towing multiple suitcases in series.

According to the previous technology, as shown in China's No. 103203186 "Luggage Coupler", it mainly uses a four-link structure to maintain the parallelogram's swing to respond to the change in the angle of two suitcases in series. However, The following problems need to be overcome in practical application of this technology:

First, its four-link structure is a kind of "constrained motion chain", and it must keep parallelogram swing, so the overall swing angle is not large, which causes the four-link tow when travelling in series on a large gradient or undulating ground. The rod structure will not be smooth, making dragging very laborious.

2. The four-link structure cannot provide cushioning when towing through the asphalt road, so the vibration situation is quite large, which makes the towing feel extremely uncomfortable.

In view of this, the inventors have continually conceived, researched, and developed the present invention.

The main content of the present invention is to provide a suitcase coupling, wherein The container includes a first socket, a second socket, and a connecting rod group. Among them, the first socket is provided with a first assembly part which is detachable to the first suitcase; and the second socket is provided with a detachable part. It is installed in the second assembly part of the second suitcase and is equipped with a damping structure; one end of the connecting rod group is pivotally connected to the first socket, and the other end is coupled to the damping structure. When traction occurs between the seats, the link group can be moved to respond, and the other end of the link group must pass through the damping structure to produce longitudinal movement and longitudinal damping value.

In this way, the present invention can increase the angle change of the towing of the suitcase in series, so that the towing is more labor-saving and smooth, and it is sufficient to respond to the slope or the undulating ground, and further, the towing vibration situation Minimize it and make it feel more comfortable, so it can further improve the degree of cooperation with the user.
