Problems solved by technology
However, there are many defects in the current rudder stock. The bottom of the rudder stock is soaked in seawater and river water for a long time. It will be corroded by sea water, and corrosion spots will be formed on the surface of the rudder stock, which will affect the service life of the rudder stock. How to protect the rudder stock and how to quickly assemble it The protective sleeve has become the primary problem to be solved; in addition, the material properties of the forged steel are easy to cause wear on the surface of the rudder stock, which will reduce the efficiency of the rudder stock to transmit torque, scrap the whole, and increase the cost of the enterprise

Embodiment Construction
[0018] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, a rotary lock type marine rudder stock includes an upper rod body 1 , a lower rod body 2 and a protective cover 3 . The upper rod body 1 and the lower rod body 2 are connected end-to-end. The protective cover 3 is sleeved on the lower end of the lower rod body 2 . Such as image 3 As shown, the present invention also includes a rotation locking mechanism 4 . The rotation locking mechanism 4 includes a rotation screw 41 , a driving block 42 and a locking block 43 . The rotating screw 41 is connected with the driving block 42 in rotation and movably. Such as figure 2 As shown, the lower rod body 2 is provided with a drive chamber 21 and two locking chambers 22 inside. The locking cavity 22 is arranged on two sides of the driving cavity 21 and communicates with each other. The locking cavity 22 extends to...

The invention discloses a rotational locking type ship rudderstock. The rotational locking type ship rudderstock comprises an upper rod body, a lower rod body, and a protection sleeve; the upper rod body and the lower rod body are connected end to end; the protection sleeve is connected at the lower end of the lower rod body in a sleeving manner; and the rotational locking type ship rudderstock further comprises a rotational locking mechanism. According to the rotational locking type ship rudderstock, the whole movement process only needs twisting a rotational screw, and the operation process is simple and convenient.
Description
technical field [0001] The invention relates to the field of marine accessories, in particular to a marine rudder stock. Background technique [0002] The rudder stock refers to the rotating rod that connects the rudder blade and the steering gear or the tiller, and transmits the rudder torque. As we all know, the rudder stock is one of the most important components in the shipbuilding industry. The current rudder stock is generally a one-piece structure of forged steel. However, there are many defects in the current rudder stock. The bottom of the rudder stock is soaked in seawater and river water for a long time. It will be corroded by sea water, and corrosion spots will be formed on the surface of the rudder stock, which will affect the service life of the rudder stock. How to protect the rudder stock and how to quickly assemble it The protective sleeve has become the primary problem to be solved; in addition, the material properties of the forged steel are easy to caus...
