Description

Technical Field

[0001] The invention relates to the technical field of outboard motor brackets, and in particular to a portable transport bracket for an outboard motor. Background Art

[0002] An outboard motor is a propulsion engine installed outside the hull, usually suspended on the outside of the stern, also known as an outboard motor. Existing outboard motors can be disassembled when idle for storage, maintenance, replacement, etc. As an advanced engine, outboard motors are usually transported with matching transfer brackets to prevent component damage.

[0003] For example, the utility model disclosed in the publication number CN213413803U discloses a storage and transportation rack for outboard motors for boats. By providing a U-shaped support device, the outboard motor can be reversely mounted on the bracket. When in use, the outboard motor does not need to be disassembled and then installed on the boat. The outboard motor can be transported to the boat and directly installed on the hull. For example, the utility model with announcement number CN214874890U discloses an outboard motor trolley, which can achieve a fixed connection between the outboard motor and the support plate by only clamping the clamp on the support plate, and at this time the outboard motor remains in a vertical state, saving the area required to accommodate the outboard motor and reducing the floor space occupied by the utility model. A material pocket is provided, and the staff can put small items such as tools into the material pocket and transport them together with the outboard motor.

[0004] However, the above-mentioned transport bracket for outboard motors still has the following problems during actual use: although the outboard motor is placed and transported by a U-shaped support device, there are large differences in the specifications and sizes of existing outboard motors. Therefore, the U-shaped support device does not have an extension mechanism, which may easily cause bottoming problems during transportation. At the same time, during transportation and installation, the transfer bracket does not have a locking mechanism, which may easily cause the transfer bracket to slide and tip over due to the shore site, causing damage to the outboard motor.

[0005] Therefore, we propose a portable outboard motor transfer bracket to solve the above-mentioned problems. Summary of the invention

[0006] An object of the present invention is to provide a portable outboard motor transfer bracket, which solves the problem of placing and transporting the outboard motor through a U-shaped supporting device. However, there are large differences in the specifications and sizes of existing outboard motors. Therefore, the U-shaped supporting device does not have an extension mechanism, which may easily cause the bottoming problem during transportation. At the same time, during transportation and installation, the transfer bracket does not have a locking mechanism, which may easily cause the transfer bracket to slide and tip over due to the shore site, causing damage to the outboard motor.

[0007] To achieve the above object, the present invention provides the following technical solution: a portable outboard motor transport bracket, comprising a load-bearing bracket, which is distributed in a left-right symmetrical manner, and the load-bearing brackets on the left and right sides are rotatably connected to the outer end of the adjustment shaft through a bearing; A bearing cross bar is fixedly arranged at the rear of the bottom end of the symmetrically arranged bearing bracket, and the bearing bracket is in an upright state by contacting the ground through the bearing cross bar, and the rear ends of the symmetrically arranged bearing cross bars are rotatably provided with translation guide wheels through bearings; The invention also includes: an extension mechanism is arranged above the load-bearing bracket, and the extension mechanism includes an extension slide bar, and the bottom end of the extension slide bar is slidably arranged inside the top end of the load-bearing bracket; A locking mechanism is arranged in front of the lower end of the bearing bracket, and the locking mechanism includes a movable guide wheel, and the movable guide wheel is rotatably arranged on the outer sides of the bottom ends of the left and right bearing brackets through bearings.

[0008] Preferably, the extension mechanism includes a lifting threaded rod, and the lifting threaded rod is rotatably arranged inside the left and right supporting brackets through bearings, and the bottom ends of the left and right lifting threaded rods are meshedly connected to the outer ends of the adjusting shafts through bevel gear groups, and the lifting threaded rods meshedly connected to the bevel gear groups are driven to rotate by rotating the adjusting shaft.

[0009] Preferably, the extension mechanism includes a lifting sleeve, and the lifting sleeve is fixedly installed inside the extension slide rod, and the bottom ends of the lifting sleeves on the left and right sides are threadedly connected to the outer wall of the lifting threaded rod inside the supporting bracket, and the lifting sleeve and the extension slide rod are driven to lift and lower by the rotating lifting threaded rod.

[0010] Preferably, the locking mechanism includes a locking sleeve, and the locking sleeve is fixedly installed on the lower front side of the left and right supporting brackets, and locking slide rods are slidably arranged on the left and right sides of the interior of the locking sleeve, and the inner ends of the left and right locking slide rods are connected to each other through a return spring.

[0011] Preferably, the locking mechanism includes a locking slot, and the locking slot is opened at equal angles inside the left and right movable guide wheels, and the left and right movable guide wheels are locked by being plugged into and locked with the outer end of the locking slide rod inside the locking sleeve through the locking slot opened inside.

[0012] Preferably, the locking mechanism includes a positioning flip plate, and the bottom end of the positioning flip plate is rotated at the center position of the outer wall of the locking sleeve through a torsion spring, and the upper end of the positioning flip plate is clamped on the upper ends of the left and right locking slide bars in the initial state, and the positioning flip plate is rotated downward so that the unrestricted locking slide bar slides outward.

[0013] Preferably, a positioning cross bar is fixedly installed on the top of the extension slide rod, and a two-way threaded rod is rotatably arranged inside the positioning cross bar through a bearing, and the outer walls of the two-way threaded rods on the left and right sides are threadedly connected with interference sliders, an extension cross plate is elastically slidably arranged at the rear of the extension slide rod, and pushing bevel blocks are fixedly arranged on the left and right sides in front of the extension cross plate, and the symmetrically arranged pushing bevel blocks and the interference sliders fit each other.

The resistance sliders fit with the push inclined blocks on the inner side of the extended cross plate, and the resistance sliders contact the inclined surface of the push inclined blocks to drive the extended cross plate to move and adjust in the front and rear directions, thereby adapting to the width of different outboard motor positioning claws to prevent the outboard motor from tilting and dislocating during installation and movement.

[0016] 3. By flipping the positioning flip piece, it is disengaged from the locking slide bars on the left and right sides, and the outer end of the locking slide bar is inserted into the locking slot hole provided inside the movable guide wheel by the return spring to lock and limit the movable guide wheel, thereby improving the stability of the load-bearing bracket and the outboard motor above it during the stationary process and preventing the displacement or even tipping of the outboard motor caused by the displacement of the outboard motor.

The resistance bracket is re-engaged with the resistance slot through the resistance column, and the inclined guide wheel and the movable guide wheel can form support by oblique pulling, thereby improving the convenience of transportation on unpaved roads.
