[0026] The present invention will now be described in further detail with reference to the accompanying drawings, but this is not intended to limit the scope of protection of the present invention.

[0027] Embodiment of this utility model:

[0028] A shipborne weapon support column includes a swivel support, a lifting and adjusting component, and a base sleeve component. The swivel support is located above the lifting and adjusting component, which is partially located within the base sleeve component. The lifting and adjusting component includes an adjuster seat, a small bevel gear assembly, and a large bevel gear assembly. The small bevel gear assembly includes a small bevel gear shaft, a small bevel gear adjusting sleeve sleeved on the small bevel gear shaft, and a small bevel gear. The large bevel gear assembly includes a lifting screw, a lifting screw head, and a large bevel gear sleeved on the lifting screw head. The small bevel gear and the large bevel gear are toothed together within the adjuster seat. Rotating the small bevel gear shaft sequentially rotates the small bevel gear assembly and the large bevel gear assembly, thereby adjusting the lifting screw in the lifting and adjusting component to screw into or out of the base sleeve component.

[0029] Furthermore, the base sleeve component includes a nut, a nut seat, and a base. The nut seat is fixedly connected inside the base to form a double-layered cylindrical body with a sandwich layer. The nut is located at the outlet position of the inner hole of the nut seat. The lifting screw is screwed into or out of the nut seat through the nut.

[0030] In this embodiment, the nut seat and the base are fixedly connected by screws. After the nut is screwed into the nut seat, it is then fixed by bolts to prevent the nut from rotating relative to the nut seat.

[0031] Furthermore, the lifting and adjusting components also include a bearing housing, a deep groove ball bearing, a thrust ball bearing, and a guide cylinder; the bearing housing is laterally fixedly connected to the adjuster seat;

[0032] Furthermore, the two ends of the small bevel gear shaft are connected to the adjuster seat and the bearing seat respectively through deep groove ball bearings; the large bevel gear is located on the lifting screw head, and the small bevel gear and the large bevel gear are connected by gear meshing in the adjuster seat. The lifting screw is connected to the adjuster seat through deep groove ball bearings and thrust ball bearings. The adjuster seat is also connected to the guide cylinder. The guide cylinder is located in the interlayer between the nut seat and the base, and plays a guiding role when the lifting screw is screwed into or out of the nut seat.

[0033] In this embodiment, the small bevel gear is fixed to the small bevel gear shaft and the large bevel gear is fixed to the lifting screw by a flat key;

[0034] Furthermore, a waterproof locking cover is provided between the adjuster seat and the base sleeve component. The bottom of the waterproof locking cover component is fixedly connected to the base in the base sleeve component. By changing the inner diameter of the waterproof locking cover component, the passage or obstruction of the guide cylinder in the lifting adjustment component can be selected.

[0035] Furthermore, the waterproof locking cover component includes a clamp, a waterproof cover, and a locking screw. The waterproof cover is fixedly connected to the base, and the clamp is located above the waterproof cover. The inner diameter of the clamp is adjusted by rotating the locking screw.

[0036] In this embodiment, the friction between the clamp and the guide cylinder is increased or decreased by changing the inner diameter of the clamp, so as to enable the lifting adjustment component to pass through or be blocked.

[0037] Furthermore, it also includes a folding handle component, which includes a folding handle and a rocker arm. The rocker arm is connected to a small bevel gear shaft, and the folding handle is movably connected to the rocker arm.

[0038] Furthermore, except for standard parts, the entire column is made of duplex stainless steel.

[0039] The installation process is as follows:

[0040] First, install the nut on the nut seat and tighten the two tapered set screws on both sides of the nut. Assemble the nut seat into the base and secure it to the bottom of the base's cylindrical body with screws. A flat-end set screw (not shown in the diagram) can also be used to adjust the tightness of the fit between the nut and the lead screw. See [link to diagram]. Figure 5 , Figure 6 ;

[0041] The second step involves applying sealant to the flange interfaces of the bottom seat assembly and the waterproof lock cover assembly, then securing them together with screws. Next, insert the guide tube, aligning the key with the guide groove on the base (i.e., the vertical groove in the diagram), and then insert the guide key, tightening it with two tapered screws. See also... Figure 5 , Figure 6 ;

[0042] The third step is to assemble the lifting screw: Assemble the lifting screw head and the lifting screw together, and connect and fix them with a cylindrical pin; install a thrust ball bearing on the assembled screw, then install the lower part of the adjuster seat, then install two deep groove ball bearings and tighten them, then install the large bevel gear adjusting shim, which can adjust the tooth contact condition of the large and small bevel gears; then install the large bevel gear, then install the large bevel gear cover on top, and finally tighten the screws onto the lifting screw head. See [link to relevant documentation]. Figure 7 .

[0043] Fourth step: First, install a rotating lip seal ring into the bearing housing, then install a deep groove ball bearing; pass the pinion shaft through the left hole of the adjuster seat, then through the small bevel gear, the small bevel gear adjusting sleeve, and the right hole of the adjuster seat, then install the bearing housing (previously assembled in step 1) onto the pinion shaft on the right side; install a deep groove ball bearing inside the end cover, then install it onto the left end of the pinion shaft and the left side of the adjuster seat; install the folding handle component on the right end of the pinion shaft, then place the rocker arm cover on the end face and tighten it with hexagonal head bolts. See [link to previous steps]. Figure 2 .

[0044] Fifth, and finally, connect the components obtained in steps two and four to the lower interface of the adjuster seat using screws to form a complete unit. Figure 1 The shipborne weapon support column.

[0045] The column's operating cycle and working principle are as follows:

[0046] The locking screw in the rotating waterproof cover assembly increases the inner diameter of the clamp, releasing the locking function of the waterproof cover component. The folding handle is then manually cranked to raise or lower the lifting adjustment component, completing the ascent or descent of the shipborne column. The column's adjustable range is 0-200mm. When the desired height is reached, the locking screw is manually rotated again, decreasing the inner diameter of the clamp and tightening the guide cylinder, thus locking the waterproof cover component. The ascent or descent of the shipborne column is then complete.
