Description

Technical Field

[0001] The utility model relates to the technical field of aluminum tubes, in particular to a high-pressure resistant reinforced seamless tube. Background Art

[0002] Aluminum tube is a kind of nonferrous metal tube, which refers to a metal tubular material made of pure aluminum or aluminum alloy through extrusion and is hollow along its entire longitudinal length. It may have one or more closed through holes, with uniform wall thickness and cross section, and is delivered in a straight line or in a roll. It is widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home furnishing and other industries.

[0003] At present, due to the high cost of aluminum, the production cost of solid aluminum tubes is high. However, when hollow aluminum tubes are used, the hollow structure greatly reduces the strength of the aluminum tubes. During use, they are often subjected to large external forces. Due to the soft nature of aluminum, they are easily deformed, bent, or even broken, thus affecting their use. Therefore, it is necessary to strengthen the aluminum alloy tubes to increase their service life. To this end, we propose a high-pressure resistant reinforced seamless tube. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As mentioned in the background art, the prior art often encounters large external forces during use. Since aluminum is soft in nature, it is easy to deform, bend or even break, thus affecting the use.

[0021] The utility model provides a high-pressure resistant reinforced seamless pipe.

[0022] Example 1

[0023] Reference Figure 1 A high-pressure resistant reinforced seamless pipe, comprising an inner pipe 1 and an outer pipe 2, both of which are aluminum alloy pipes;

[0024] The inner wall of the outer tube 2 is provided with an outer mounting tube 6, and the inner wall of the outer mounting tube 6 is evenly provided with arc tubes 3 in contact with each other, and the arc tubes 3 can support a large external force;

[0025] The arc tube 3 is provided with reinforcing ribs 4 evenly inclined, and adjacent reinforcing ribs 4 are in contact with each other. The reinforcing ribs 4 can improve the structural strength of the arc tube 3, thereby improving the structural strength of the aluminum alloy tube. The reinforcing ribs 4 in contact with each other can squeeze adjacent reinforcing ribs 4 when subjected to force, further improving the compressive resistance.

[0026] An inner mounting tube 7 is disposed on the outer wall of the inner tube 1 , and the arc tubes 3 are all connected to the inner mounting tube 7 .

[0027] The arc tube 3 is provided with a protruding rod 5 which is slidably connected to the adjacent arc tube 3 , which can improve the supporting capacity at the end of the arc tube 3 , thereby avoiding the problem of weakness caused by the lack of reinforcing ribs 4 at the end of the arc tube 3 .

[0028] The inner wall of the outer mounting tube 6 is evenly provided with buffer pads 8, and the buffer pads 8 are closely connected to the outer wall of the arc tube 3. The buffer pads 8 are made of rubber material and can buffer and protect the extrusion transmitted from the outer mounting tube 6, thereby protecting the inner tube 1 well and preventing the inner tube 1 from deformation, bending or even breaking.

[0029] The outer wall of the outer mounting tube 6 is evenly provided with buffer pads 9 , and the buffer pads 9 are closely connected to the inner wall of the outer tube 2 . The buffer pads 9 are made of rubber material, and the extrusion transmitted from the outer tube 2 can be buffered and protected by the buffer pads 9 .

[0030] Example 2

[0031] Reference Figure 1 The buffer pad 1 8 and the buffer pad 2 9 are arranged alternately, so that the buffer pad 1 8 and the buffer pad 2 9 can play a buffering effect on the extrusion in any direction without fully covering the outer mounting tube 6, so that the outer mounting tube 6 can have space to be installed and fixed with the outer tube 2 and the arc tube 3 without affecting the buffering of external extrusion.

[0032] The rest of the structure is the same as that of Example 1.
