Besides, a position limiting is able to be fitted between the main frame and the auxiliary frame for limiting the position and guided sliding of the pipe to achieve the main efficacy of dragging the boat.

Description

Boat telescopic trailer

The invention relates to a marine telescopic trailer, in particular to a telescopic trailer structure in which an auxiliary vessel can be smoothly introduced into water, which realizes the auxiliary vessel in the port by utilizing the guide sliding extension design of the main frame corresponding to the plurality of sub-frames. A launching program that facilitates hauling and transportation is an invention application.

According to the improvement of economic ability, it has the ability to engage in various leisure activities. Among them, water sports is the primary choice for many people. Yachts or jet skis are obviously necessary tools. Driving yachts and jet skis ride on the water. It is believed that many people dream of living, and these water appliances are moved from the big ship to the water surface or moved from the water surface to the ship due to their considerable volume and weight, and often need to be lifted and lowered by the lifting structure attached to the ship's raft. The pedals are assisted to move smoothly; however, when such watercrafts are to be launched at the port or by the sea, they are usually towed by a crane mechanism using a crane mechanism, or a small water motorbike is carried by several people. However, in the above-mentioned manner, it is necessary to spend a lot of money to ask for towing the vehicle, or to manually waste the manpower, and the handling process is also caused by human factors, accidentally hurting the ship, etc. not ideal.

The reason is that the inventor is in the light of the shortcomings of the above-mentioned existing structure in practical implementation, and is a tireless spirit, and with its rich professional knowledge and many years of With the help of practical experience and improvement, a design of a marine telescopic trailer is provided to increase the advantages of use.

The main object of the present invention is to provide a marine telescopic trailer, in particular to a telescopic trailer structure in which an auxiliary vessel can be smoothly introduced into water, which can be used to achieve an auxiliary vessel by utilizing a guide sliding extension design of the main frame corresponding to several sub-frames. The launching process that facilitates towing and transporting in the port is the invention for the purpose of the invention.

The purpose and function of the marine telescopic trailer of the present invention is achieved by the following technology: it mainly has a main frame body carrying a ship, a towing hook portion collided with the vehicle on the main frame body, and positioning of the fixed vessel a hook portion and a top height device capable of lowering the height of the vessel, wherein the pipe body of the main frame body is provided with a plurality of sub-frames which can be extended or collapsed, and the pipe member is provided with a guide The sliding group corresponds to the pipe fittings for the sub-frame body to guide the sliding telescopic displacement; thereby, the sliding frame extension design corresponding to the plurality of sub-frames of the main frame body allows the vessel to be transported in the port, and the auxiliary vessel can be smoothly introduced into the water. The launcher.

The marine telescopic trailer further has a limit group at the front end of the sub-frame pipe fitting to correspond to the limit-guided sliding action between the pipe members, and the effect of assisting the sliding is achieved.

The marine telescopic trailer further comprises a limiting piece between the corresponding sub-frame body of the main frame body or the corresponding sub-frame body of the sub-frame body to correspond to the function of the limit function between the pipe parts.

The marine telescopic trailer further has a take-up group on the main frame body, and the hooks of the take-up group are correspondingly hooked on the final set of sub-frames, thereby Drive to correspond to the number of sub-frames are sequentially retracted from the main frame.
