Description

Technical Field

[0001] The utility model relates to the technical field of aluminum materials, in particular to a lightweight telescopic aluminum tube. Background Technique

[0002] An aluminum tube is a type of non-ferrous metal tube, referring to a metal tubular material that is extruded from pure aluminum or aluminum alloy and is hollow along its entire longitudinal length. The aluminum tube is a high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity in the annealed, freshly quenched, and hot states, and good spot welding weldability.

[0003] For example, the authorized announcement number "CN220956327U" is a lightweight telescopic aluminum tube. By setting a corrosion-resistant layer on the outer surfaces of the first aluminum tube and the second aluminum tube, the problem that the outer surface of the aluminum material is easily corroded when exposed is solved, and the effect of extending the service life of the aluminum material is achieved. However, for the existing lightweight telescopic aluminum tube, since two bolts and nuts in different directions are used in cooperation to fix the telescopic aluminum tube, in actual operation, when telescoping the second aluminum tube, the position of the mounting hole and the corresponding bolt on one side need to be manually adjusted before it can be inserted. This leads to multiple attempts during installation until the two different bolts are accurately inserted into the mounting holes, and then the respective nuts can be rotated to achieve the fixing effect. Therefore, installing and fixing one aluminum tube requires multiple steps and consumes too much time, affecting the use efficiency of the lightweight telescopic aluminum tube.

[0004] At the same time, for the existing lightweight telescopic aluminum tube, since devices capable of finely adjusting the distance and length are provided at the front and rear ends of the aluminum tube, although it is more convenient to use, the screw for finely adjusting the distance is relatively slender. While the slender screw needs to cooperate with a locking nut to achieve the adjustment function and support the pressure and weight at both ends of the aluminum tube, such an overly slender screw bears the supporting role that the aluminum tube itself needs to bear. Not only is the screw prone to bending and deformation, but also the problem of breakage at the connection of both ends of the aluminum tube is likely to occur, greatly affecting the use firmness of the lightweight telescopic aluminum tube. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems of low use efficiency and poor use firmness of the lightweight telescopic aluminum tube, and to propose a lightweight telescopic aluminum tube.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Design a lightweight telescopic aluminum tube, including a first aluminum tube, a second aluminum tube and a connecting plate. The second aluminum tube is slidably sleeved inside the first aluminum tube. An aluminum tube length quick adjustment structure is provided inside the first aluminum tube. One end of the outer wall of the first aluminum tube is fixedly connected with a high-strength adjustment structure for the lightweight telescopic aluminum tube. A second aluminum tube sliding guide structure is provided inside the first aluminum tube. An installation block is fixedly installed at the end of the second aluminum tube.

[0008] Preferably, the aluminum tube length quick adjustment structure includes a first vertical tube and through holes. A plurality of the through holes are fixedly opened inside the second aluminum tube. The first vertical tube is movably connected inside the first aluminum tube. The first vertical tube is slidably connected with the inside of the through holes. A threaded groove is fixedly opened inside the first vertical tube. A screw is threadedly connected inside the threaded groove. A second vertical tube is fixedly connected to the outside of the screw. The second vertical tube is movably connected to the outside of the first aluminum tube.

[0009] Preferably, a sealing layer is movably sleeved at the end of the first aluminum tube. The end of the first vertical tube is movably connected to the outer wall of the first aluminum tube. The end of the second vertical tube is movably connected to the outer wall of the first aluminum tube.

[0010] Preferably, the high-strength adjustment structure for the lightweight telescopic aluminum tube includes a fixed seat and sliding rods. The fixed seat is fixedly installed at the end of the first aluminum tube. A plurality of sliding rods are fixedly installed on the outer wall of the fixed seat. A first pressing plate is slidably sleeved on the outside of the plurality of sliding rods. A second pressing plate is slidably sleeved on the other end of the outside of the plurality of sliding rods. Trapezoidal blocks are fixedly installed inside the first pressing plate and the first pressing plate. A nail-in block is movably connected to the top inside the first pressing plate and the first pressing plate. A top plate is fixedly installed at the top of the nail-in block.

[0011] Preferably, the connecting plate is fixedly installed on the outer wall of the installation block. The connecting plate is fixedly installed on the outer wall of the second pressing plate. A plurality of reserved holes are fixedly opened inside the two connecting plates.

[0012] Preferably, the second aluminum tube sliding guide structure includes a limiting plate and sliding grooves. The two sliding grooves are fixedly opened on the inner wall of the first aluminum tube. A slider is slidably connected inside the two sliding grooves. A limiting plate is fixedly installed inside the two sliders. One side of the limiting plate is fixedly connected to the end of the second aluminum tube.

[0013] A lightweight telescopic aluminum tube proposed by the present utility model has the beneficial effects that when the length of the aluminum tube is adjusted to the required position, first insert the first vertical tube into the inner side of the through holes opened in the first aluminum tube and the second aluminum tube below. At this time, only need to insert the second vertical tube with the screw rod into the corresponding through hole, and rotate the first vertical tube and the second vertical tube in the opposite directions. By using the first vertical tube with a separate thread groove, it can be quickly and conveniently docked and installed with the second vertical tube with the screw rod, improving the use efficiency of the lightweight telescopic aluminum tube.

[0014] Through the depth at which the nail-in block is knocked and squeezed inward, the trapezoidal block can be pushed to both sides. The pushed trapezoidal block will form a pressure that expands outward, prompting the first pressing plate and the second pressing plate to separate along the sliding rod. After separation, the first pressing plate and the second pressing plate can adjust the distance between the fixed seat and the connecting plate, achieving a fine-tuning effect. Through the fine-tuning mode of the nail-in block, the fixation between the rear side of the first aluminum tube and the connecting plate is made more firm and the diameter is thicker, improving the firmness of the lightweight telescopic aluminum tube in use.
