Description

Technical Field

[0001] The utility model relates to the technical field of outboard motor connection, in particular to an outboard motor fastening connection device. Background Art

[0002] In recent years, emergency management bureaus and fire departments in various cities across my country have purchased a large number of flood-prevention rubber boats, speedboats and other surface vessels as flood-prevention materials for transportation on the water and for tasks such as personnel evacuation and rescue. The purchase quantity has increased year by year.

[0003] Outboard motors are used as the power source for driving boats. Most of them are connected to the boats in an external form. For example, a 30-horsepower outboard motor can be hung on an inflatable boat or taken down and hung on a speedboat. Different ratios are used according to different tasks. However, multiple hanging and taking will cause metal fatigue from a physical point of view. Another factor is the human factor. Sometimes the mission is urgent, the light is dim, the weather is bad, etc., which causes the outboard motor operator to set off without 100% tightening the outboard motor fixing bolts. When the boat is performing high-maneuverability maneuvers, the outboard motor is separated from the boat due to the huge external throwing force and falls into the water, which may cause property losses to the country, unit or individual at the least, or personal injury, water pollution, etc. at the worst.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] like Figure 1-3As shown, according to the utility model, an outboard motor fastening connection device is disclosed, including a connecting rod body, the connecting rod body including a first connecting support rod 110, a second connecting support rod 120 and a third connecting support rod 130 are respectively vertically provided at both ends of the first connecting support rod 110, the second connecting support rod 120 and the third connecting support rod 130 are parallel and located on the same side of the first connecting support rod 110, the length of the third connecting support rod 130 is greater than the length of the second connecting support rod 120, a support block 121 is vertically penetrated at one end of the second connecting support rod 120, and one end of the third connecting support rod 130 is a threaded structure and is threadedly connected with a butterfly nut 131.

[0021] Embodiment 1:

[0022] In the present application, the connecting rod body can be integrally formed or welded by three stainless steel materials, and one end of the third connecting support rod 130 is threaded, and the top of the second connecting head 132 is chamfered to make it spherical, which can prevent it from hurting the human body; the support block 121 is a round stainless steel block with a hole drilled in the middle and then passes through the second connecting support rod 120 and is welded.

[0023] Embodiment 2:

[0024] like Figure 2-3 As shown, a corresponding first connecting hole is opened in advance on the outboard engine base 310, and a corresponding second connecting hole is opened on the stern plate 200. In order to increase the service life, stainless steel sleeves can be set in the first connecting hole and the second connecting hole to connect the second connecting support rod 120 and the third connecting support rod 130. When in use, the stern plate 200 and the outboard engine 300 are first fixed with the original bolt assembly 320, and then the third connecting support rod 130 is passed through the second connecting hole and lifted upward. After being lifted for a distance, the first connecting head 122 of the second connecting support rod 120 is allowed to enter the first connecting hole, and the support block 121 is allowed to press against the outboard engine base 310. Finally, the butterfly nut is tightened on the third connecting support rod 130.
