Description

Technical Field

[0001] This utility model relates to the field of aluminum tube device technology, and in particular to a lightweight telescopic aluminum tube. Background Technology

[0002] Telescopic aluminum tubing is an aluminum tube whose length can be adjusted arbitrarily. It is usually composed of multiple aluminum tube sections, which are connected by a mandrel or other means to facilitate extension and retraction. Due to its convenient and quick adjustment performance, it is widely used in display stands, light stands, antennas, fishing rods and other fields.

[0003] Depending on the installation scenario, there are telescopic aluminum tubes on the market that can be adjusted in length. Generally, the two ends of such aluminum tubes are fixed by threaded installation. However, the surfaces used to install the aluminum tubes on both sides are not entirely perpendicular to the aluminum tube surface. This requires a certain degree of adjustment to the installation angle on both sides of the telescopic aluminum tube. Therefore, a lightweight telescopic aluminum tube is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lightweight telescopic aluminum tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight telescopic aluminum tube includes an adjusting sleeve, a connecting rod slidably connected to the inner wall of the adjusting sleeve, a plurality of reinforcing ribs fixedly connected to the inner wall of the adjusting sleeve, a plurality of fitting grooves being formed on the surface of the connecting rod, the fitting grooves being adapted to the reinforcing ribs, and an adjusting installation mechanism being installed on the surfaces of the adjusting sleeve and the connecting rod.

[0007] Preferably, the adjustment and installation mechanism includes a connecting plate fixedly connected to the surface of the adjusting sleeve and the connecting rod, and a first gear disk and a second gear disk are rotatably connected to the inner walls of a pair of connecting plates, wherein the first gear disk and the second gear disk mesh.

[0008] Preferably, both the first gear disk and the second gear disk have contact plates fixedly connected to their surfaces, and the contact plates have multiple threaded holes on their surfaces.

[0009] Preferably, both the first gear disk and the second gear disk have multiple positioning holes on their surfaces, and a U-shaped rod is slidably connected to the inner wall of the connecting plate, the U-shaped rod being adapted to the inner wall of the positioning hole.

[0010] Preferably, a pull ring is fixedly connected to the surface of the U-shaped rod, and a spring is fixedly connected to the surface of the U-shaped rod, with one end of the spring fixedly connected to the surface of the connecting plate.

[0011] Preferably, a pair of L-shaped plates are fixedly connected to the surface of the adjusting sleeve, and the L-shaped plates are threadedly connected to the inner wall of the adjusting sleeve with threaded rods. The surface of the connecting rods is provided with multiple threaded grooves, and the threaded rods are threadedly connected to one of the threaded grooves.

[0012] Preferably, the surface of the connecting rod is provided with a plurality of first lightweight holes and a plurality of second lightweight holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] Pulling the pull ring releases the positioning of the first and second gear discs. Rotating the first gear disc causes the second gear disc to rotate synchronously, adjusting the included angle between a pair of contact plates. Releasing the pull ring allows the U-shaped rod to reset under the action of the spring, inserting into the corresponding positioning hole for stability, thus adapting to the needs of different mounting surfaces. Before installing the adjusting sleeve and connecting rod as a whole, after adjusting their positions, the threaded rod and threaded groove engage to maintain the stable positioning of the adjusting sleeve and connecting rod, achieving the telescopic adjustment effect.

[0022] By setting multiple reinforcing ribs 7, the structural strength of the adjusting sleeve 1 is enhanced. By setting the fitting groove 5, the reinforcing ribs 7 are installed and avoided. By setting the adjusting installation mechanism, the relative extension length of the adjusting sleeve 1 and the connecting rod 2 is adjusted. At the same time, the installation angles on both sides of the adjusting sleeve 1 and the connecting rod 2 are adjusted and positioned to adapt to complex installation conditions.

[0023] In this utility model, the adjustment and installation mechanism includes a connecting plate 10 fixedly connected to the surface of the adjusting sleeve 1 and the connecting rod 2. The inner walls of a pair of connecting plates 10 are rotatably connected to a first gear disk 15 and a second gear disk 16, and the first gear disk 15 and the second gear disk 16 mesh with each other.

[0024] By setting the connecting plate 10, the installation of the first gear disk 15 and the second gear disk 16 is kept stable. By setting the first gear disk 15 and the second gear disk 16 to mesh, the rotation of one part drives the rotation of the other part.

[0025] In this utility model, the surfaces of the first gear disk 15 and the second gear disk 16 are both fixedly connected with contact plates 17, and the surface of the contact plates 17 is provided with multiple threaded holes 18.

[0026] Contact installation is achieved by setting the contact plate 17, and threaded fixing is achieved by setting the threaded hole 18 to cooperate with the screw.

[0027] In this utility model, the surfaces of the first gear disk 15 and the second gear disk 16 are provided with a plurality of positioning holes 14, and the inner wall of the connecting plate 10 is slidably connected with a U-shaped rod 12, which is adapted to the inner wall of the positioning hole 14.

[0028] By setting a U-shaped rod 12, which cooperates with the corresponding multiple positioning holes 14, the first gear disk 15 and the second gear disk 16 are synchronously fixed to prevent them from rotating.

[0029] In this utility model, a pull ring 13 is fixedly connected to the surface of the U-shaped rod 12, and a spring 11 is fixedly connected to the surface of the U-shaped rod 12. One end of the spring 11 is fixedly connected to the surface of the connecting plate 10.

[0030] By setting a pull ring 13, the U-shaped rod 12 is moved by the pull ring 13, and by setting a spring 11, the U-shaped rod 12 is reset.

[0031] In this utility model, a pair of L-shaped plates 8 are fixedly connected to the surface of the adjusting sleeve 1. The L-shaped plates 8 are threadedly connected to the inner wall of the adjusting sleeve 1 with threaded rods 9. The surface of the connecting rod 2 is provided with multiple threaded grooves 3, and the threaded rod 9 is threadedly connected to one of the threaded grooves 3.

[0032] By setting the L-shaped plate 8, the thread of the threaded rod 9 and the threaded groove 3 is kept stable. By setting the threaded rod 9, the positions of the adjusting sleeve 1 and the connecting rod 2 are positioned and fixed.

[0033] In this utility model, the surface of the connecting rod 2 is provided with a plurality of first lightweight holes 4 and the surface of the connecting rod 2 is provided with a plurality of second lightweight holes 6.

[0034] By setting multiple first lightweight holes 4 and second lightweight holes 6, the overall weight of the adjusting sleeve 1 and the connecting rod 2 is reduced.

[0035] Working principle: In use, firstly, disconnect the threaded connection of the threaded rod 9 to one of the threaded grooves 3, then slide the adjustment sleeve 1 and the connecting rod 2 to adjust their positions. When the positions are appropriate, the threaded engagement of the threaded rod 9 and the threaded groove 3 maintains the stable positioning of the adjustment sleeve 1 and the connecting rod 2. When installing the adjustment sleeve 1 and the connecting rod 2 as a whole, the pull ring 13 can be pulled to pull the U-shaped rod 12 out of the positioning hole 14, releasing the positioning of the first gear disk 15 and the second gear disk 16. Rotating the first gear disk 15 can drive the second gear disk 16 to rotate synchronously, allowing the pair of contact plates 17 to adjust the included angle between them. Releasing the pull ring 13, the U-shaped rod 12 returns to its original position under the action of the spring 11, allowing the U-shaped rod 12 to be inserted into the corresponding positioning hole 14 and remain stable to adapt to the needs of different installation surfaces. By setting multiple first lightweight holes 4 and second lightweight holes 6, the overall weight of the adjustment sleeve 1 and the connecting rod 2 is reduced. With the above structure, while adjusting the telescopic length, the installation angle can be positioned and adjusted to adapt to the installation needs in different environments.
