The outboard motor fixture 100 of the present embodiment can realize the conversion of the underwater attitude, the water attitude, and the rushing posture of the propeller 200. For details, please refer to FIG. 8 to FIG. 11 and related FIGS. 1 to 7, wherein FIG. 8 is propulsion. FIG. 9 is a schematic diagram showing the internal three-dimensional structure of the outboard motor fixing device of the first embodiment when the propeller is in the water posture, and FIG. 10 is the propeller water posture. FIG. 11 is a schematic diagram showing the three-dimensional structure inside the outboard motor fixing device of the first embodiment when the propeller is in a beach attitude.

Fig. 8 shows the state of the outboard motor fixing device 100 when the propeller 200 is in the underwater posture. At this time, the card stop 33 is engaged with the first card 18, that is, the first card 18 corresponds to the underwater posture of the pusher 200. Specifically, the latching stop 33 projects under the force of the return spring 32, and then forms an engagement limit with one side of the latching pin 17, and the notch portion 25 is on the other side of the latching pin 17 and constitutes a stepped limit. The positional restriction on both sides enables the pusher 200 to remain fixed without being affected by external force, so that the pusher 200 can efficiently push the movement of the vessel. It can be imagined that when the propeller 200 is switched from the water attitude to the underwater attitude, the propeller 200 is rotated downward by its own gravity, and the latching block 33 slides along the guiding surface 162 of the guiding slider 16 to the card position. At the pin 17, under the interaction force between the inclined surface 331 of the retaining block 33 and the latching pin 17, the latching stop 33 is automatically retracted, and then slides over the latching pin 17, and the return spring 32 continues to act on the latching stop 33. It is extended and engaged with the notch portion 24 to engage with the latch pin 17.

It can be seen from the above description that the card pin 17 is detachably inserted into the pin hole 112 to form the first card position 18, wherein the number of the pin holes 112 may be multiple, and the plurality of pin holes 112 along the support bracket Arrange in the direction of rotation. If the latch pin 17 is inserted into the pin hole 112 at different positions, the corresponding first latch 18 will be formed at different positions, and then the underwater attitude of the pusher 200 is adjusted, that is, the pusher 200 is perpendicular to the water. Under or at an angle, it is placed under water.

Fig. 9 shows the state of the outboard fixing device 100 when the propeller 200 is in the water posture. At this time, the card stop 33 is engaged with the second card 19, that is, the second card 19 corresponds to the water attitude of the pusher 200. Specifically, the card stop 33 projects under the urging force of the return spring 32, and is engaged with the support surface 161 of the guide slider 16, restricting the downward rotation of the pusher 200 by its own gravity. At the same time, the upper baffle 14 of the clamping bracket 1 can also limit the continued upward rotation of the pusher 200. Similarly, when the propeller 200 is switched from the underwater attitude to the water attitude, the propeller 200 is rotated upward by the external force, and the latching block 33 is slid along the guiding surface 162 of the guiding slider 16 to the supporting surface 161. Continuing to rotate upwards, the latching stop 33 no longer has the pushing action of the guiding surface 162, but protrudes under the action of the return spring 32, and then engages the supporting surface 161.

Fig. 10 shows the state of the outboard motor fixture 100 during the underwater attitude and the water attitude switching of the propeller 200. When switching between the underwater attitude and the underwater attitude of the propeller 200, it is first necessary to pull the wrench 31 upward to overcome the force of the return spring 32, and the latching block 33 slides up along the guiding slot 24, and then the first card. The position 18 or the second card position 19 is disengaged, and then the pusher 200 is rotated about the first rotating shaft 5 by external force or self-gravity, and the corresponding latching block 33 is guided along the guiding slider 16. The surface 162 slides and is always in the retracted state under the pushing action of the guiding surface 162. When the sliding reaches the first card position 18 or the second card position 19, the force is not required to be applied to the wrench, that is, the first card position can be automatically 18 or the second card 19 is engaged.

Fig. 11 shows the state of the outboard motor fixing device 100 when the propeller 200 is in a beach state. When there are many reefs in the water and the water depth is shallow, the propeller 200 is required to freely move when encountering the reef to relieve the impact force of the reef, so that the propeller 200 is in the beach state, that is, the propeller 200 can freely move. status. First, the handle 44 of the second locking mechanism 4 is pulled, and the punch pin 41 moves along the third shaft hole 221, so that the first end portion 411 of the punch pin 41 no longer restricts the upward movement of the interference wrench 31; 44 to overcome the return spring force of the lateral spring 43, and then pull the wrench 31 upward, when it exceeds the beach pin 41, release the handle 44, the beach pin 41 is reset under the return spring force of the lateral spring 43, that is, the first end 411 restores the protruding portion, and then the first end portion 411 restricts the downward movement of the wrench 31. At this time, the latching stop 33 is also retracted into the guiding slot 24, and is no longer engaged with the first latching position 18 or the second. Card In position 19, the pusher 200 is freely rotatable about the first rotating shaft 5, at which time the pusher 200 is in a beach state.

In other embodiments, the second locking mechanism 4 may not include the lateral spring 43. In order to place the pusher 200 in the rushing state, the handle 44 is first pulled to drive the rushing pin 41 to move along the third shaft hole 221, so that The first end portion 411 of the rushing beach pin 41 no longer restricts the upward movement of the interference wrench 31; then the wrench 31 is pulled upward, and when it exceeds the rushing pin 41, the handle 44 is pushed to reset the rushing pin 41, ie, The one end portion 411 restores the protruding portion, and then the first end portion 411 restricts the downward movement of the wrench 31. At this time, the pusher 200 can freely rotate around the first rotating shaft 5, and is in a beach state.

Different from the prior art, the outboard fixing device in this embodiment includes a clamping bracket, a fixing base and a first locking mechanism, and the clamping bracket is clamped on the stern or the bow plate, and is provided with the first a card seat and a second card position; the fixing seat is used for fixing the propeller and is rotatably connected with the clamping bracket; the first locking mechanism comprises a wrench, a return spring and a card stop block, and the wrench is rotatably connected with the fixing seat, and the card position The stopper is connected with the wrench, and the return spring elastically acts on the latching stopper. When the fixing seat rotates relative to the clamping bracket, the locking block can be respectively moved to the first card position and the second card position, and protrudes under the action of the spring, and is engaged with the first card position or the second card position. Wherein the first card position corresponds to the underwater attitude of the propeller and the second card position corresponds to the water attitude of the propeller. When it is necessary to switch the propeller between the underwater attitude and the water attitude, only the wrench needs to overcome the force of the return spring to retract the latching stop, release the engagement, and then rotate the fixed seat relative to the clamping bracket. The underwater attitude and the water attitude of the propeller can be switched, and the operator can realize the above switching with one hand, and the operation is more convenient. Further, the second anchoring mechanism is further included in the outboard fixing device, and the position of the wrench is restricted by the punching pin in the second locking mechanism, and then the latching block of the connected connection is no longer stuck. The first card position or the second card position is combined to enable the propeller to rotate freely and in a beach state, which can alleviate the impact force when hitting the reef.
