Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0024] Please see Figures 1 to 3 A support device for an outboard motor gearbox 50 includes a support 10 and support rods 30. The support rods 30 are horizontally positioned beside the support 10 and are located near the upper end of the support 10. The ends of the support rods 30 are movably connected to the support 10. The two support rods 30 are parallel and spaced apart from each other, and are located at the same height. The gearbox 50 is placed on the two support rods 30. The two support rods 30 can move towards each other or away from each other along the width direction of the support 10 to accommodate gearboxes 50 of different sizes. The two support rods 30 provide support on both sides of the gearbox 50, thus elevating the gearbox 50. The propeller 60 is located below the middle of the two support rods 30, and the propeller 60 does not interfere with the support 10 or the support rods 30. The gearbox 50 can be kept in a top-facing position for maintenance, facilitating operation.

[0025] A base 20 is provided below the support 10 to provide a support platform for the support 10. Several casters 21 are provided at the bottom of the support 10 to move the gearbox 50. Preferably, the casters 21 are self-locking casters 21, which can be fixed during maintenance to prevent the support 10 from moving. In this embodiment, the base 20 includes four pipes welded end-to-end, and four casters 21 are respectively fixed at the four corners of the base 20. The support 10 is positioned above the base 20, and the base 20 has a hollow structure in the middle, increasing the longitudinal depth that the support 10 can support. As another embodiment, the base 20 can be a flat plate structure.

[0026] In this embodiment, the support 10 includes two square tubes 11 vertically arranged on both sides of the base 20. The two square tubes 11 are welded and fixed to the base 20. The two square tubes 11 are connected by a horizontally arranged guide rod 12. The end of the support rod 30 is movably sleeved on the guide rod 12. The two support rods 30 can move along the guide rod 12, moving closer or further apart to adjust the distance between the two support rods 30 and support gearboxes 50 of different sizes. At the same time, the two support rods 30 can move towards each other to clamp the gearboxes 50 located on them, so that the gearboxes 50 remain stable on the support rods 30. As another embodiment, the support 10 can be a flat plate structure.

[0027] Preferably, an inclined reinforcing rib 43 is provided between the support 10 and the base 20, and the support 10, the reinforcing rib 43 and the base 20 form a right-angled triangle to increase the connection strength between the support 10 and the base 20.

[0028] Preferably, the support 10 is positioned near one end of the base 20, and the support rod 30 on the support 10 extends from one end of the base 20 to the other. When overhauling the gearbox 50, the movable gearbox 50 can be moved to change its position on the support rod 30, adjusting the center of gravity of the overall support device so that it is located above the middle of the base 20, thereby reducing the risk of the support 10 tipping over when the support rod 30 is under load.

[0029] Preferably, the support rods 30 are horizontally arranged, and the two support rods 30 can provide symmetrical support on both sides of the gearbox 50 to stabilize it on the support rods 30. The support rods 30 are tilted, causing them to slide relative to the gearbox 50.

[0030] Preferably, the guide rod 12 is positioned near the upper end of the square tube 11 to increase the support height of the support rod 30; when the gearbox 50 is supported on the support rod 30, there is no solid space below the support rod 30, and the propeller 60 connected to the lower part of the gearbox 50 does not interfere with the support 10 or the base 20.

[0031] The guide rod 12 is a straight rod, and optionally, the cross-section of the guide rod 12 is polygonal or circular. When the cross-section of the guide rod 12 is square, the end of the support rod 30 is provided with a square hole, and it is movably sleeved on the outside of the guide rod 12 through the square hole. The support rod 30 supports the gearbox 50, and the inner wall of the square hole cooperates with the outer wall of the guide rod 12 to prevent the support rod 30 from rotating around the guide rod 12 under force.

[0032] In this embodiment, the guide rod 12 is a round rod. To ensure that the support rod 30 can only move along the guide rod 12 and to prevent the support rod 30 from rotating under load, a fixing rod 13 is provided below the guide rod 12. The fixing rod 13 is parallel to the guide rod 12. A connecting seat 40 is provided at the end of the support rod 30. The connecting seat 40 has a guide hole 301 and a connecting hole 302. The guide rod 12 is inserted into the guide hole 301, and the fixing rod 13 is inserted into the connecting hole 302. The connecting seat 40 connects both the guide rod 12 and the fixing rod 13, thus preventing the support rod 30 from rotating under load.

[0033] The connecting seat 40 includes a first side 41 and a second side 42 that are vertically connected. The first side 41 is fixedly connected to the support rod 30, and the connecting hole 302 and the guide hole 301 are formed on the second side 42. Considering the large weight of the gearbox 50 and the propeller 60 below it, preferably, a reinforcing rib 43 is provided between the first side 41 and the second side 42, and the first side 41, the second side 42 and the reinforcing rib 43 form a support triangle structure to improve the support strength of the support rod 30.

[0034] As another implementation method, such as Figure 2 and Figure 3 As shown, the support rod 30 is an L-shaped rod with a connecting hole 302 and a guide hole 301 on its shorter side. The guide hole 301 is closer to the other side than the connecting hole 302. The support rod 30 is movably sleeved on the guide rod 12 and the fixing rod 13 through the guide hole 301 and the connecting hole 302.

[0035] In this embodiment, an adjusting rod 31 is connected to the support rod 30. The adjusting rod 31 is parallel to the guide rod 12. The adjusting rod 31 is a screw, one end of which is rotatably connected to the connecting seat 40, and the other end passes through the support 10 and extends outside the support 10. Specifically, a nut 32 is fixedly welded to the end face of the square tube 11 facing the other square tube 11. The adjusting rod 31 passes through the square tube 11 and is threadedly connected to the nut 32. The other end of the adjusting rod 31 is located outside the support 10. By rotating the adjusting rod 31, the adjusting rod 31 moves relative to the nut 32, and drives the support rod 30 to move along the guide rod 12, adjusting the distance between the two support rods 30. The threaded connection between the adjusting rod 31 and the nut 32 facilitates the fixing of the support rod 30, limits the movement of the support rod 30 after movement, keeps its position relative to the guide rod 12 relatively fixed, and improves the support stability of the support rod 30.

[0036] In another embodiment, a threaded hole is provided on the square tube 11, and the adjusting rod 31 is threadedly connected to the square tube 11.

[0037] In this embodiment, each of the two support rods 30 is provided with an adjusting rod 31. The two adjusting rods 31 are respectively connected to the two square tubes 11 through nuts 32. The distance between the two support rods 30 can be changed by rotating the two adjusting rods 31 respectively.

[0038] Preferably, the adjusting rod 31 is provided with a handle 311 at the end located outside the support 10, so as to move the support rod 30 by rotating the adjusting rod 31 through the handle 311.

[0039] Please see Figure 2 The propeller 60 moves forward in the direction of the length of the gearbox 50. Figure 2 The diagram shows the support rod 30 providing support on both sides of the gearbox 50 in the width direction. It can be imagined that by moving the support rod 30 to increase the distance between the two support rods 30 and adjusting the direction of the gearbox 50, the support rod 30 can provide support at both ends of the gearbox 50 in the length direction. The support rod 30 can be adjusted according to actual usage requirements.

[0040] Most gearboxes 50 have vortex baffles 51 on their outer walls. The vortex baffles 51 extend along the forward direction of the propeller 60 and are symmetrically arranged on the outer walls of both sides of the gear along the forward direction of the propeller 60. In this embodiment, the support rod 30 is supported below the vortex baffles 51.

[0041] Further, please refer to Figure 3 A pressure plate 33 is provided on the support rod 30. One end of the pressure plate 33 is rotatably connected to the top surface of the support rod 30 via a pin. The position of the pressure plate 33 can be adjusted by rotating it so that it is partially positioned above the gearbox 50. A fastener (not shown in the figure) is provided on the pressure plate 33, and a fixing hole is provided on the support rod 30. The fastener is connected to the fixing hole of the support rod 30. In this embodiment, the fastener is a bolt. Tightening the fastener downwards presses the pressure plate 33 against the support rod 30, causing the pressure plate 33 to press down on the gearbox 50, thus fixing the gearbox 50 to the support rod 30 and improving the stability of the support rod 30 in supporting the gearbox 50. Preferably, the pressure plate 33 is located near the end of the support rod 30, and the connection point between the fastener and the pressure plate 33 is close to the connection point between the pressure plate 33 and the support rod 30, to reduce the impact of the fastener connection on the support rod 30 on the supportable area of ​​the support rod 30.

[0042] The pressure plate 33 rotates around the pin shaft. Before supporting the gearbox 50, the pressure plate 33 is rotated to expose the top of the support rod 30, so that the gearbox 50 can be placed on the support rod 30. After the gearbox 50 is adjusted to a suitable position, the pressure plate 33 is rotated so that the pressure plate 33 rotates above the vortex baffle 51 of the gearbox 50. Then the fastener is tightened, and the fastener drives the pressure plate 33 to press down, so that the vortex baffle 51 is in close contact with the support rod 30. The pressure plate 33 limits the position above the vortex baffle 51, fixing the gearbox 50 on the support rod 30 and improving the support stability. During operation, the gearbox 50 is disengaged from the support rod 30.

[0043] In another embodiment, the guide rod 12 is a square rod with a linear guide rail on it. A slider is mounted on the linear guide rail and is fixedly connected to the support rod 30. The slider is driven by a motor to move along the linear guide rail, thereby moving the support rod 30 and adjusting the distance between the two support rods 30.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
