Description

Technical Field

[0001] This utility model relates to the technical field of fishing platform equipment, specifically to linear guide rail type fishing platform support legs. Background Technology

[0002] A fishing platform, as a fishing tool, provides anglers with a flat and comfortable operating platform in complex waters. The platform's legs are a crucial component. Traditionally, the length of the platform's legs is adjusted using fixed clips. Assembling, disassembling, and adjusting the leg length requires the angler to be submerged in the water, which is cumbersome, inconvenient, and poses safety hazards when operating in the water.

[0003] A patent with publication number CN204540468U is disclosed in the prior art. The solution is assembled from an inner tube, an outer tube, a fixed sleeve, a rotating sleeve, a screw, and a disc foot. The fixed sleeve needs to have a threaded hole. The top of the screw is preferably a hexagonal bolt head. The telescopic leg is assembled as follows: the fixed sleeve and the disc foot are fixed to both sides of the inner tube, and the rotating sleeve is fixed through the table surface. The bottom of the screw passes through the rotating sleeve and the outer tube and is screwed to the fixed sleeve. When adjusting the telescopic leg of the fishing platform with the above structure, you only need to turn the hexagonal bolt head with a wrench to make the screw drive the inner tube to extend and retract back and forth. Moreover, the design of the hexagonal bolt head passing through the table surface is not only convenient to rotate, but also applicable to a variety of adjustment tools. Both ordinary Y-type wrenches and special Z-type wrenches can be used.

[0004] Existing devices, including those mentioned above, have gradually revealed shortcomings in the technology with use, mainly in the following aspects:

[0005] First, the existing fishing platform support legs have too large a gap between them and the outer tube during the raising and lowering process. This results in a large circumferential gap between the support legs and the outer tube when adjusting the height of the fishing platform support legs, affecting the accuracy of height adjustment.

[0006] Secondly, the existing height adjustment structure of the fishing platform legs is all welded as a whole, which means that when the parts are damaged later, the whole thing needs to be replaced, increasing production costs.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a linear guide rail type fishing platform support leg, which solves the problem that in traditional technologies, the gap between the fishing platform support leg and the outer tube is too large during the lifting and lowering process, resulting in a large circumferential gap between the support leg and the outer tube when adjusting the height of the fishing platform support leg, thus affecting the accuracy of height adjustment.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A linear guide rail type fishing platform support leg includes an outer tube, an adjusting column is installed inside the outer tube, the adjusting column is slidably set by a screw structure, and a linear guide rail structure is provided axially between the inner wall of the outer tube and the outer wall of the adjusting column.

[0011] As an optimized solution, the linear guide rail structure includes a guide rail fixed axially to the outer wall of the adjusting column, and a guide groove matching the guide rail is provided on the inner wall of the outer tube.

[0012] As an optimized solution, the linear guide structure includes a guide rail fixed axially to the inner wall of the outer tube, and a guide groove matching the guide rail is provided on the outer wall of the adjusting column.

[0013] As an optimized solution, the screw structure includes an adjusting screw rotatably mounted on the upper end of the outer tube, and the upper end of the adjusting column is provided with an adjusting screw groove that matches the adjusting screw.

[0014] As an optimized solution, a fixing ring is fixedly connected to the upper end of the outer tube, and a rotating column is coaxially fixedly connected to the upper end of the adjusting screw. The outer diameter of the rotating column is smaller than the outer diameter of the adjusting screw, and the rotating column is rotatably installed in the hole of the fixing ring.

[0015] As an optimized solution, the rotating column is threaded with a limiting nut and a locking nut located above the fixing ring, and the lower surface of the limiting nut is in frictional contact with the upper surface of the fixing ring.

[0016] As an optimized solution, a square column is fixed to the upper end of the rotating column, and a square drive seat is inserted into the square column.

[0017] As an optimized solution, the lower end of the square drive seat is provided with a square groove that matches the square column.

[0018] As an optimized solution, a screw is inserted into the upper end of the square drive seat, and a locking thread groove is opened at the upper end of the square column, with the end of the screw threadedly connected to the locking thread groove.

[0019] As an optimized solution, the upper end of the square drive seat is provided with a hidden groove, and the upper end of the screw is lower than the top of the hidden groove.

[0020] As an optimized solution, the outer end of the adjusting column is threadedly connected to a support seat.

[0021] As an optimized solution, the outer end of the adjusting column is provided with a threaded groove, and the upper end of the support base is fixed with a stud that matches the threaded groove.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] By providing a linear guide rail structure along the axial direction between the inner wall of the outer tube and the outer wall of the adjusting column, the circumferential rotation gap between the outer tube and the adjusting column can be reduced, overcoming the problem that the large circumferential gap affects the accuracy of height adjustment. Furthermore, this adjustment method for the fishing platform legs is more stable than the traditional special-shaped tube method.

[0024] By using a rotating column whose outer diameter is smaller than that of the adjusting screw, the upper end of the rotating column rubs against the lower surface of the fixed ring. The lower surface of the limiting nut rubs against the upper surface of the fixed ring, thus limiting the axial position of the adjusting screw. The limiting nut is locked by a locking nut, thus limiting its position. The upper end of the square drive seat is fitted with a screw, enabling a detachable connection of the square drive seat, which facilitates assembly and disassembly and overcomes the problem of inconvenient replacement of parts caused by welding in traditional technology.

The lower surface of the limiting nut 15 is in frictional contact with the upper surface of the fixed ring 14.

[0038] A square column 11 is fixed to the upper end of the rotating column 10. A square drive seat 9 is inserted into the square column 11. By setting the directional drive seat, it can be manually turned by a handle or driven to lift by an electric handle, which is convenient and quick.
