Problems solved by technology

[0003] Although the installation structure of the above-mentioned handle can also meet the requirements of users, since the handle is a relatively slender component, after installing such a handle, the propeller will be bulky during transportation, which will inevitably cause The defects of inconvenient packaging and high transportation cost, and the screw installation method between the handle and the connecting shaft, the assembly efficiency is also low

Embodiment 1

[0026] Example 1, such as Figure 1 to Figure 6 As shown, the propeller includes a handle 100 and a housing 200, wherein the housing 200 is assembled from an upper cover 201 and a lower cover 202, and the housing has a shaft hole A for placing the following connecting shaft, and a transmission is installed (not shown in the figure).

[0027] The quick installation structure of the handle includes the handle 100 and the connecting shaft 300 installed in the above-mentioned shaft hole for connecting the transmission. The connecting shaft 300 has an inner hole 301 which is inserted and linked with the head of the handle 100. A non-circular hole is adopted, and the matching form between it and the head of the handle can be a square hole and a square shaft, or a keyway can be used, so that the rotation of the handle 100 can drive the connecting shaft 300 to rotate, and then the speed changer can be rotated. to adjust the direction and speed of the boat as needed.

[0028] In this...

Embodiment 2

[0036] Example 2, such as Figure 7 to Figure 9 As shown, it is different from the above-mentioned embodiment 1 in that the gear ring 31' and the connecting shaft 300' are made into a split structure, although the assembly efficiency is a little low, but it is convenient for processing.

Abstract

The invention relates to a rapid installation structure for a propeller handle. The rapid installation structure for the propeller handle comprises the handle and a connecting shaft installed in a shaft hole in a shell of a propeller and used for being connected with a transmission. The connecting shaft is provided with an inner hole, wherein the head of the handle is inserted in the inner hole in a linkage mode. The rapid installation structure for the propeller handle is characterized in that the end, facing the handle, of the connecting shaft is connected with a position stop ring, multiple elastic sheets distributed in the circumferential direction extend out from the end face, opposite to the handle, of the position stop ring in the axial direction, and the free ends of the elastic sheets gradually approach one another, so that a conic face is formed by the elastic sheets; the portion close to the head of the handle is designed into a cone matched with the conic face, a protrusion is arranged at the front end of the cone, after the head of the handle is inserted into the position stop ring and extends into the inner hole of the connecting shaft, each elastic sheet is tightly attached to the surface of the cone, and the free end of each elastic sheet abuts against the protrusion. The rapid installation structure for the propeller handle is small in size in the transportation process, low in transportation cost and convenient to assemble.

Description

technical field [0001] The invention relates to a marine propeller, in particular to a quick installation structure for a marine propeller handle. Background technique [0002] The ship propeller can control the speed and direction of the ship with hands or feet. When the propeller is controlled by hand, a handle needs to be set on the propeller. The head of the handle extends into the propeller housing and rotates with a The connecting shaft that is arranged in the shaft hole of the housing is fixed, and the front end of the connecting shaft is connected with the speed changer in the housing. Turning the handle like this, the speed changer can be turned to make the boat advance in the desired direction and speed gear. But the installation of the existing handle is that the manufacturer fixes the handle in the housing in advance before leaving the factory, and the user does not need to install it after purchasing, as long as it is used as required. [0003] Although the ins...
