Direction adjustment structure for small boat

Abstract

The invention discloses a direction adjustment structure for a small boat. The direction adjustment structure for the small boat comprises a steering wheel, a first rotating shaft, a cardan joint, a second rotating shaft, a worm and gear mechanism, a third rotating shaft, a first connecting rod, a dowel bar, a second connecting rod, a guide mechanism, a third connecting rod, a fourth rotating shaft and a rudder. The steering wheel is installed on the first rotating shaft, the first rotating shaft is connected with the second rotating shaft through the cardan joint, the second rotating shaft is connected with the worm wheel input end of the worm and gear mechanism, the worm output end of the worm and gear mechanism is connected with the third rotating shaft, the third rotating shaft is connected with one end of the dowel bar through the first connecting rod, the other end of the dowel bar is connected with the second connecting rod, the third connecting rod is connected with the fourth rotating shaft, the rudder is installed at the lower end of the fourth rotating shaft, and both the second connecting rod and the third connecting rod are connected with the guide mechanism. The direction adjustment structure for the small boat can achieve a self-lock function in the process of adjusting directions through the arrangement of the worm and gear mechanism, avoids the problem that the directions can not be adjusted quickly due to resistance of water, and is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of direction adjustment, and more specifically relates to a direction adjustment structure for a small boat. Background technique [0002] The steering structure of a traditional small boat generally includes a driving device, a propeller and a steering rudder. The power is transmitted to the propeller through the driving device, the propeller is driven to rotate, and then the steering rudder is turned through the connecting rod to control the forward direction of the boat. However, the problem with this structure is that during the direction adjustment process, the connecting rod does not have self-locking performance, and when there is a large water resistance, the direction adjustment cannot be better realized. Therefore, it is necessary to design a new type of dinghy with a direction regulating structure. Contents of the invention [0003] The object of the present invention is to provide a direction...
