In this embodiment, the handle 121 is screwed or unscrewed to clamp and loosen the ship board or the stern plate, but it is also conceivable that in other embodiments, the pressure plate 122 can move freely in the sliding rod or the sliding groove to adjust the position of the pressure plate 122, and then the position of the pressure plate 122 in the sliding rod or the sliding groove is locked by the snap ring or the latch pin, so as to clamp and loosen the ship board or the stern plate.

With reference to fig. 3 and 4, further, the gear rack 300 is located between the two clamping plates 110, the two clamping plates 110 are respectively provided with the detent portions 101, and the detent portions 101 of the two clamping plates 110 are disposed opposite to each other. The clamping portion 310 of the gear rack 300 includes a clamping rod 311, the clamping rod 311 is located between the two clamping plates 110, and two ends of the clamping rod 311 are clamped to the clamping portions 310 located at two sides respectively.

Referring to fig. 3, 4 and 5, fig. 5 is a schematic structural diagram of a clamping member in an embodiment of the gearshift device of the present application, in which only a single clamping plate 110 is shown.

The positioning portion 101 includes a first detent 111 and a second detent 112, and the first detent 111 and the second detent 112 are located at different positions of the clamping member 100. The gear rack 300 can move to the first detent 111 and the second detent 112 respectively during the rotation of the clamp base 200 relative to the clamping member 100, so as to engage the engaging rod 311 with the first detent 111 or the second detent 112.

The connection rod 311 is engaged with the first detent 111 corresponding to the underwater posture of the marine propeller, i.e. the marine propeller is located underwater, so as to push the ship to advance. The clamping rod 311 and the second clamping part 112 are clamped to correspond to the water attitude of the marine propeller, namely the upwarping attitude. If the marine propeller is in an idle state, the marine propeller can be lifted up and away from the water surface for protection. The marine propeller has the advantages that the marine propeller is prevented from being corroded or influenced by underwater organisms, microorganisms and the like for a long time in the water, and the service life of the marine propeller is prolonged.

When the marine propeller is installed on a ship, an included angle between a long axis of the marine propeller and a vertical plane in the vertical plane may be referred to as an inclination angle of the marine propeller, and the inclination angle may affect the maximum propulsion efficiency of the marine propeller, thereby affecting the maximum speed at which the ship travels, and the inclination angles at which the maximum propulsion efficiency can be achieved when the same marine propeller is matched with different ships are different, and the inclination angles at which the maximum propulsion efficiency can be achieved when the same marine propeller and the same ship are in different storm environments are also different, so that the marine propeller also needs to be convenient to adjust the inclination angle in the using process so as to be compatible with different ships or use environments.

Thus, in this embodiment, the first detent 111 includes a plurality of gear positions, and the respective different gear positions will form different positions of the first detent 111. When the clamping rod 311 is clamped at different gears, the underwater posture of the marine propeller can be adjusted, so that the included angle between the marine propeller and the clamping part 100 is adjusted and controlled through a plurality of gears, the propelling directions of the driving devices 13 such as the propeller in water are basically kept horizontal, the propelling efficiency is guaranteed, and the marine propeller has a good propelling effect.

gear positions

111a, 111b, 111c, 111d, each corresponding to a different angle between the marine propulsor and the clamping member 100, e.g., 111a, 111b, 111c, 111d may correspond to angles of 0 °, 5 °, 10 °, and 15 ° between the marine propulsor and the clamping member 100.

Optionally, the first detent 111 and the second detent 112 are detent grooves, that is, the first detent 111 and the second detent 112 are groove bodies into which the detent lever 311 can be snapped.

The clamping member 100 further includes a clamping baffle 130, the locking portion includes the clamping baffle 130 and a locking hole 145 formed on the clamping baffle 130, the clamping baffle 130 is located on one side of the clamping portion 101, and the clamping rod 311 moves perpendicular to the clamping baffle 130 and on one side of the clamping baffle 130.

When the clamping rod 311 is clamped on the clamping portion 101, the clamping rod 311 moves to be opposite to the locking hole 145, and the clamping rod 311 can pass through the locking hole 145, so that the clamping rod 311 cannot move, and the clamp base 200 and the clamping component 100 are fixed to each other.

The locking hole 145 may be provided at one position where any one of the locking portions 101 corresponds to the clamp fence 130, for example, in the present embodiment, the locking hole 145 is provided at one position of the clamp fence 130 adjacent to the second lock 112, and when the lock lever 311 is inserted into the locking hole 145 of the second lock 112, the marine propeller can stably maintain a state of being lifted up and lifted off the water surface.

In this embodiment, an elastic component (not shown) is disposed in the clamping rod, and elastic potential energy is stored in the elastic component, so that when the clamping rod 311 does not move to the locking hole 145, the clamping rod 311 abuts against the clamping baffle 130 under the action of the elastic component, and the clamping rod 311 generates a certain force on the clamping baffle 130. When the clamping rod 311 moves to the locking hole 145 and faces the locking hole 145, the elastic component releases elastic potential energy, pushes the clamping rod 311 into the locking hole 145, and converts the elastic potential energy into kinetic energy of the clamping rod 311 moving to penetrate into the locking hole 145.

Therefore, in the gear shifting device of the present embodiment, when the clamping portion 310 moves to the locking portion 101, the clamping rod 311 of the clamping portion can be automatically inserted into the locking hole 145 to lock the clamping portion 310 to the clamping portion 101, so as to maintain the ship propeller fixed to the clamp base 200 at a certain angle with respect to the clamping member 100.

Referring to fig. 6, fig. 6 is a front view of the gear shifting device in the embodiment of fig. 2. The elastic assembly may include a fixing member 320 and a first spring 330.

When the clamping rod 311 and the clamping baffle 130 abut against each other, the first spring 330 is compressed by the fixing piece on the clamping rod 311 and the gear clamping frame 300, the first spring 330 stores elastic potential energy, and when the clamping rod moves to the locking hole 145 and faces the locking hole 145, the elastic potential energy is released by the elastic assembly, the elastic potential energy is released by the first spring 330, the clamping rod 311 is pushed into the locking hole 145, and the clamping rod 311 penetrates through the locking hole 145.

In other embodiments, the first detent 111 and the second detent 112 can have locking holes 145 formed thereon, so that when the latch lever 311 moves to the first detent 111 or the second detent 112, the latch lever can be automatically pushed into the corresponding locking hole 145 by the elastic component, thereby locking the clamp base 200 and the clamping member 100 to each other.

Please refer to fig. 5, 6 and 7. Fig. 7 is a schematic structural diagram of the reset assembly in the embodiment of fig. 5. In order to better release the locking relationship between the catch rod 311 and the first detent 111 or the second detent 112, in the present embodiment, the locking portion further includes a reset component (not numbered).

The reset assembly is arranged in the locking hole 145 and can push out the clamping rod 311 in the locking hole 145. After the reset means pushes the catching rod 311 out of the locking hole 145, the elastic means stores elastic potential energy, the catching portion 310 can be disengaged from the catching portion 101, the clamp base 200 and the clamping member 100 are unlocked, and the catching portion 310 can be switched to another catching portion 101. The length of the reset assembly is greater than the depth of the detent opening 145 so that the reset assembly can fully push the catch lever 311 out of the detent opening 145.

Specifically, the reset assembly may include a reset button 141, a second spring 142, a reset seat 143, and a connector 144.

The reset seat 143 includes a first section of post 1431 and a second section of post 1432 fixedly connected to the first section of post 1431, and the reset button 141 includes a button 1411 and a third section of post 1412 fixedly connected to the button 1411.

The reset button 141 is provided with a first connection hole 1413, the reset base 143 is provided with a second connection hole 1433, and the connection member 144 penetrates the second connection hole 1433 from one side of the second connection hole 1433 and enters the first connection hole 1413 to connect the reset button 141 and the reset base 143.

Referring to fig. 8 and 9 together, fig. 8 is a cross-sectional view of the clamping assembly of the embodiment of fig. 5 at a position of the reset assembly, and fig. 9 is a schematic view of the embodiment of fig. 8 when the latch lever is inserted into the locking hole.

Specifically, the detent apertures 145 include a first-stage aperture 1451, a second-stage aperture 1452, and a third-stage aperture 1453. Second segment 1452 is disposed intermediate first segment 1451 and third segment 1453, and third segment 1453 is disposed closer to clamping bar 311 than first segment 1451.

The first and

second posts

1431, 1432 and the cap 1411 have a diameter greater than the second hole 1452 and the third post 1412 has a diameter less than or equal to the second hole 1452, such that the third post 1412 of the reset button 141 can pass through the second hole 1452 and slide in the second hole 1452, while the cap 1411 and the reset seat 143 cannot pass through the second hole 1452.

When the latch bar 311 is not inserted into the locking hole 145, the third leg 1412 is inserted into the second leg hole 1452 from a side of the clamp stop 130 away from the latch bar 311, the button cap 1411 is received in the first leg hole 1451, and the reset seat 143 is received in the third leg hole 1453. The reset button 141 is fixedly connected with the reset seat 143. Meanwhile, the third column 1412 has a certain sliding distance in the second hole 1452, and because the diameters of the first column 1431, the second column 1432 and the button 1411 are larger than the diameter of the second hole 1452, when the third column 1412 slides in the second hole 1452, the button 1411 and the second column 1432 can limit the sliding of the third column 1412, so that the third column 1412 is prevented from slipping out of the second hole 1452.

The first section of post 1431 has a diameter that is larger than the diameter of the second section of hole 1452, and the second section of hole 1452 is closer to the reset button 141 than the first section of post 1431. The second spring 142 is sleeved on the second section of post 1432, and one section of the second spring 142 is connected to the first section of post 1431, and the other end is connected to the clamp stop 130 in the third section of hole 1453. The third leg of post 1412 is retained by the second spring 142 in a state where the third leg of post 1412 slides into abutment with the button cap 1411 and the retainer plate 130, preventing the third leg of post 1412 from loosening within the second leg of bore 1452.

Referring to fig. 6 to 9, when the latch rod 311 is inserted into the locking hole 145, the latch rod 311 is pushed by the first spring 330 to penetrate into the third section hole 1453 and abut against the reset seat 143 or the connecting member 144, the third section post 1412 slides in the second section hole 1452, and the reset seat 143 and the reset button 141 move toward the first section hole 1451. At this time, the first segment 1431 and the clamping stop 130 compress the second spring 142, and the second spring 142 generates a force resisting the movement of the clamping rod 311 toward the locking hole 145.

In order to maintain the state that the clamping rod 311 is inserted into the locking hole 145, in this embodiment, the elastic coefficient of the second spring 142 is smaller than that of the first spring 330, so that the clamping rod 311 pushes the reset seat 143 to compress the second spring 142 under the action of the first spring 330, and the second spring 142 stores elastic potential energy.

If the state that the clamping rod 311 is inserted into the locking hole 145 needs to be released, the reset button 141 needs to be pushed at one side of the reset button 141, so that the reset button 141 drives the reset seat 143 and the connecting piece 144 to push the clamping rod 311 out of the locking hole 145. In this embodiment, the sliding process of the reset seat 143 or the connecting member 144 in the third hole 1453 is larger than the depth of the third hole 1453, so that a part of the reset seat 143 or the connecting member 144 can slide out of the third hole 1453.

Therefore, in the present embodiment, the engagement between the engaging portion 310 and the engaging portion 101 can be released by pressing the reset button 141, and the locking between the clamp base 200 and the clamping member 100 is released, so that the angle between the marine propeller fixed to the clamp base 200 and the clamping member 100 can be adjusted. For the marine propeller in the water attitude, the marine propeller can be unlocked without being lifted, and the operation is convenient and labor-saving.

Referring to fig. 2, 5 and 10, fig. 10 is a schematic perspective view of the shift hook of the embodiment of fig. 2. Further, the gearshift device 11 may further include a shift hook 400. The gear retractor 400 is rotatably connected to the clamp base 200, and the gear retractor 400 is located between the gear rack 300 and the clamp base 200. The gear clamping frame 300 is provided with a hooking portion 340 on one side close to the gear retractor 400, a pulling hook portion 410 is arranged at one end of the gear retractor 400 close to the hooking portion 340, and the pulling hook portion 410 can be clamped with the hooking portion 340. Optionally, the gear retractor 400 is rotatably connected to the clamp base 200 via a rotating shaft.

When the hooking portion 340 and the hooking portion 410 are engaged, the first detent 111a of the grip member 100 is engaged with the shift stage holder 300, so that the marine propeller is in an operation mode in which the angle with the grip member 100 is maintained at 0 °. When the hooking part 340 and the pulling hook part 410 are in the separated state, the marine propeller is in the beach flushing mode, and the marine propeller is prevented from being damaged

The normal working mode of the marine propeller is that the marine propeller moves forwards or backwards in a normal propelling working state. The beach flushing mode mainly has the advantage that the marine propeller can freely rise when being subjected to external impact force. When the bottom of the marine propeller collides with an acting force opposite to the running direction of a boat, the gear clamping frame 300 is in a free state and can be correspondingly tilted when being impacted, so that the damage to a clamp of the marine propeller or the marine propeller is reduced or avoided.

Specifically, the gearshift hook 400 further includes a rotation shaft 420, a hook portion 410, a coil spring 430, and a shift lever 440. The rotating shaft 420 is disposed on the clamp base 200, the gear retractor 400 is disposed on the rotating shaft 420 in a penetrating manner, the gear retractor 400 can rotate around the rotating shaft 420, and the coil spring 430 is disposed on the rotating shaft 420. The shift lever 440 is located on the other side of the rotating shaft 420 of the gearshift hook 400, and the shift lever 440 is used for receiving external force. In this embodiment, the shift lever 440 is disposed in a rod shape and located at an upper portion of the side of the gear retractor 400 close to the clamp base 200. In other embodiments, the lever 440 may be configured in a button shape, a belt shape, or other shapes, and is not limited herein.

The hook portion 410 of the gear retractor 400 is engaged with/disengaged from the hooking portion 340 under the action of the coil spring 430 and the action of external force against the coil spring 430, so that the marine propeller is switched between the normal working mode and the beach flushing mode; in addition, the gear switching of the marine propeller or the switching of the underwater posture on water can be realized. If the gear retractor 400 is under the action of the coil spring 430 to engage the engaging portion 310 with the first detent 111a, so that the gear rack 300 is fixed to the first detent 111a, then the gear retractor 400 is under the action of an external force to rotate against the action of the coil spring 430 to disengage from the gear rack 300, so that the gear rack 300 can rotate relative to the clamping member 100 to disengage from the first detent 111a, and then the gear rack 300 is adjusted to the target gear. Therefore, the gear switching of the marine propeller or the switching of the underwater posture on water can be conveniently realized by the mode.

Specifically, when the hooking portion 340 and the hooking portion 410 are in the engaged state, the gear position bracket 300 is in the engaged state with the first position detent 111a, and at this time, the marine propeller is in the normal operation mode. When the hooking portion 340 and the pulling hook portion 410 are kept in the separated state, the gear rack 300 can be engaged with other clamping portions 101, and at this time, the marine propeller is in the beach flushing mode.

In an embodiment, after the hooking portion 340 and the pulling hook portion 410 are separated, because the gear pulling hook 400 is connected to the fixture base 200, in order to facilitate the hooking portion 340 to be connected with the pulling hook portion 410 in a clamping manner, the heavy force of the marine propeller can be utilized, so that the hooking portion 340 and the pulling hook portion 410 are automatically clamped, the use by a user is facilitated, and the clamping efficiency is improved.

With reference to fig. 2 to 8, a mode of adjusting the gear of the marine propeller by the gear shifting device 11 will be described: when the gear retractor 400 is in the normal operating mode, the latch rod 311 of the gear rack 300 is engaged with the first latch 111a, and the gear retractor 400 is engaged with the gear rack 300. The shifting lever 440 on the gear drag hook 400 is shifted to release the engagement between the gear drag hook 400 and the gear clamping frame 300, and the gear drag hook 400 is disengaged from the gear clamping frame 300 under the action of the coil spring 430. At this time, the fixture base 200 can be rotated to rotate the shift position rack to other shift positions, such as the first position 111b, the first position 111c, the first position 111d, or the second position 112. If the clamping rod 311 is rotated to the second clamping position 112, the clamping rod 311 is inserted into the locking hole 145 by the first spring 330, the clamping rod 311 is kept clamped in the second clamping position 112, and the marine propeller keeps the water attitude by the gear shifting device 11. If the marine propeller needs to be released from the marine attitude, the reset button 141 can be pressed so that the reset assembly pushes the catch rod 311 out of the locking hole 145 and the catch rod 311 can move to another gear of the marine attitude.

Referring to fig. 2, in some embodiments, the gear shifting device 11 further includes a stopping mechanism 500, and when the gear retractor 400 rotates under the action of an external force to disengage from the gear rack 300, the stopping mechanism 500 is configured to stop the gear retractor 400, so that the gear retractor 400 and the gear rack 300 are kept separated from each other, and the marine propeller is in the beach mode. The above-mentioned clamping mechanism 500 can be any structure as long as it can clamp the gear retractor 400, so that the gear retractor 400 and the gear clamping frame 300 can be kept in a separated state.

Specifically, the locking mechanism 500 includes a locking structure 510 and a limiting structure 520, the limiting structure 520 is fixedly disposed on the clamp base 200, and the locking structure 510 is slidably disposed in the limiting structure 520. When the stopping structure 510 slides to the first position relative to the limiting structure 520, the stopping structure 510 acts on the gear retractor 400 to overcome the acting force of the coil spring 430 to make the upper portion of the gear retractor 400 close to the clamp base 200, so that the hook portion 410 of the gear retractor 400 keeps separated from the hooking portion 340 of the gear rack 300. When the stop structure 510 slides to the second position relative to the limiting structure 520, the stop structure 510 disengages from the gear retractor 400, so that the upper half part of the gear retractor 400 can be close to the clamp base 200 under the action of the coil spring 430, and the pull hook portion 410 of the lower half part of the gear retractor 400 is clamped on the hooking portion 340 of the gear clamping frame 300 under the action of gravity of the marine propeller, so as to realize clamping between the two.

Therefore, the clamping structure 510 and the limiting structure 520 are matched with each other, so that the switching between the working mode and the beach flushing mode can be conveniently realized. The locking structure 510 and the limiting structure 520 may be any structures, and the marine propeller may be switched between the marine propeller operating mode and the beach flushing mode.
