Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy square tubes, in particular to an aluminum square tube which is not easily deformed by extrusion. Background Art

[0002] Aluminum alloy square tube belongs to Al-MgSi alloy, with medium strength, good plasticity and excellent corrosion resistance, especially no tendency of stress corrosion cracking, excellent weldability, corrosion resistance and cold working properties. It is a widely used and promising alloy. It can be anodized and painted, and can also be used as a building decoration material.

[0003] The existing patent CN215522290U aluminum square tube, through the buffer pressure-resistant layer, realizes the enhancement of the pressure resistance of the aluminum alloy square tube, and at the same time enhances the toughness of the alloy tube body, avoids bending and cracking, thereby greatly improving the overall quality of the square tube, ensuring the safety of users, and has a simple structure and is easy to produce. Through the mutual cooperation between the first anti-corrosion protective film and the second anti-corrosion protective film, the alloy tube body and each functional layer are protected, and its anti-corrosion ability is enhanced. Through the triangular fixing block, each inner corner position of the alloy tube body is reinforced to increase its rigidity and stability. Through the angle module, the corner position of the buffer pressure-resistant layer is reinforced;

[0004] In the above technical solution, since a buffer layer is added to the square tube body, the overall strength of the square tube will be reduced. Although it can have a certain buffering effect, it is not as high as the original strength of the square tube body. Therefore, the utility model proposes an aluminum square tube that is not easily deformed by extrusion. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and provides an aluminum square tube which is not easily deformed by extrusion.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an extruded non-deformable square tube aluminum square tube, comprising a square tube body, the square tube body comprising a square tube, a support assembly is arranged on the square tube, and an auxiliary support assembly is arranged between the square tube and the support assembly;

[0007] The support assembly includes a circular support tube, which is connected to the inner wall of the square tube. The upper and lower sides of the circular support tube are provided with first arc-shaped support plates, and the other ends of the first arc-shaped support plates are connected to the corners of the inner wall of the square tube.

[0008] As a preferred embodiment, four first arc-shaped support plates are provided in total, and the four first arc-shaped support plates form a group of two and are symmetrical to each other with a circular support tube.

[0009] The beneficial effect of adopting the above further scheme is: the first arc-shaped support plate is used to provide auxiliary support for the square tube from the vertical extruder, and the first arc-shaped support plate is deformed and bent after being subjected to arc force. The deformed first arc-shaped support plate is in contact with the second arc-shaped support plate for extrusion. At this time, the second arc-shaped support plate also has the effect of supporting the square tube when it is subjected to vertical force, and at the same time cooperates with the upper and lower ends of the circular support tube to provide auxiliary support to it, thereby further preventing the square tube from being deformed due to excessive force.

[0010] As a preferred implementation, a second arc-shaped support plate is disposed between the two first arc-shaped support plates, and the second arc-shaped support plate is connected to the square tube.

[0011] The beneficial effect of adopting the above further scheme is: the square tube is supported horizontally by the second arc-shaped support plate. When the square tube is subjected to lateral extrusion force, the second arc-shaped support plate is deformed and squeezed with the first arc-shaped support plate. At this time, the first arc-shaped support plate can provide lateral support force for the square tube. When the second arc-shaped support plate is further deformed, under the action of the circular support tube, auxiliary limiting is performed to prevent the second arc-shaped support plate from being damaged by excessive deformation.

[0012] As a preferred embodiment, the auxiliary support assembly includes a first filling plate, a circular filling plate and a second filling plate, the first filling plate is inserted between the first arc-shaped support plate and the square tube, the second filling plate is inserted between the second arc-shaped support plate and the square tube, and the circular filling plate is inserted on the circular support tube.

[0013] The beneficial effect of adopting the above-mentioned further scheme is: the overall strength of the square tube is further improved by the auxiliary support assembly, and the circular support tube, the first arc-shaped support plate and the second arc-shaped support plate are auxiliary supported by inserting the first filling plate, the circular filling plate and the second arc-shaped support plate into the corresponding installation points to prevent the square tube from being deformed after being subjected to further extrusion pressure.

[0014] As a preferred embodiment, the first filling plate, the circular filling plate and the second filling plate are all coated with a lubricating coating.

[0015] The beneficial effect of adopting the above further scheme is: the rubber lubricating coating generally refers to a coating of rubber material coated on the surface, which is used to provide friction reduction and lubrication. The lubricating coating can prevent the first filling plate, the circular filling plate and the second filling plate from getting stuck due to large friction when inserted.

[0016] As a preferred embodiment, the first filling plate is adapted to the first arc-shaped support plate and the size between the circular support tube and the square tube, the second filling plate is adapted to the size between the circular support tube and the square tube, and the diameter of the circular filling plate is adapted to the inner wall diameter of the circular support tube.

[0017] The beneficial effect of adopting the above further scheme is: the first filling plate is used to fill the gap between the first arc support plate, the first arc support plate and the square tube to prevent the square tube from being deformed when the vertical extrusion pressure is too large; the second filling plate is used to fill the gap between the second arc support plate and the square tube to prevent the square tube from being deformed when the lateral extrusion pressure is too large.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, the interior of the square tube is supported by the support assembly. When the square tube is subjected to vertical pressure, the vertical extrusion force is distributed to the circular support tube and the second arc support plate under the action of the first arc support plate. The extrusion force is reduced by the cooperation between multiple components. When the square tube is subjected to lateral extrusion force, the pressure is transferred to the first arc support plate and the circular support tube under the action of the second arc support plate. The support is provided by the cooperation between multiple components, thereby improving the support effect and preventing the square tube from being damaged or deformed.

[0020] 2. In the utility model, the supporting effect of the supporting assembly is further improved by an auxiliary supporting assembly. The first filling plate, the circular filling plate and the circular filling plate are filled into the interior of the supporting assembly to prevent the supporting assembly from being deformed due to excessive force. Since the first filling plate, the circular filling plate and the second filling plate are all made of polyurethane rubber, and since PU rubber has excellent wear resistance, tear resistance and impact resistance, the supporting effect of the supporting assembly can be further improved.

[0027] 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.

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: an extruded square tube aluminum square tube that is not easy to deform, comprising a square tube body 1, the square tube body 1 comprising a square tube 2, a support assembly 3 is arranged on the square tube 2, and an auxiliary support assembly 4 is arranged between the square tube 2 and the support assembly 3; the support assembly 3 comprises a circular support tube 31, the circular support tube 31 is connected to the inner surface wall of the square tube 2, and the upper and lower sides of the circular support tube 31 are both provided with a first arc support plate 32, and the other ends of the first arc support plates 32 are both connected to the corners of the inner wall of the square tube 2, and the interior of the square tube body 1 is supported by the support assembly 3 to prevent the square tube 2 from being deformed and damaged when subjected to pressure from the vertical or horizontal direction during use, and further the interior of the support assembly 3 is filled by the auxiliary support assembly 4, and the main function of the filling is to provide an auxiliary support effect for the support assembly 3, and under the action of the auxiliary support assembly 4, the support assembly 3 is prevented from being damaged after excessive deformation, thereby solving the technical problem that the square tube 2 is easily damaged and deformed during use.

[0029] Furthermore, Figure 2 - Figure 4As shown in the figure: there are four first arc-shaped support plates 32 in total, and two of the four first arc-shaped support plates 32 form a group and are symmetrical with each other with the circular support tube 31. A second arc-shaped support plate 33 is arranged between the two first arc-shaped support plates 32, and the second arc-shaped support plate 33 is connected to the square tube 2. The first arc-shaped support plate 32 is used to provide auxiliary support for the square tube 2 from the vertical extruder. The first arc-shaped support plate 32 is deformed and bent after being subjected to arc force. The deformed first arc-shaped support plate 32 is in contact with the second arc-shaped support plate 33 for extrusion. At this time, the second arc-shaped support plate 33 also has the function of supporting the square tube 2 vertically. The second arc-shaped support plate 33 supports the square tube 2 in the horizontal direction. When the square tube 2 is subjected to lateral extrusion force, the second arc-shaped support plate 33 is deformed and squeezed with the first arc-shaped support plate 32. At this time, the first arc-shaped support plate 32 can provide lateral support force for the square tube 2. When the second arc-shaped support plate 33 is further deformed, under the action of the circular support tube 31, auxiliary limiting is performed to prevent the second arc-shaped support plate 33 from being deformed too much and damaged.

[0030] The above solution still has the problem that the support assembly 3 may be deformed due to excessive force during use. Figure 2 As shown: In this solution, the auxiliary support assembly 4 includes a first filling plate 41, a circular filling plate 42 and a second filling plate 43. The first filling plate 41 is inserted between the first arc-shaped support plate 32 and the square tube 2, the second filling plate 43 is inserted between the second arc-shaped support plate 33 and the square tube 2, and the circular filling plate 42 is inserted on the circular support tube 31. The first filling plate 41 is adapted to the size of the first arc-shaped support plate 32 and the circular support tube 31 and the square tube 2, and the second filling plate 43 is adapted to the size of the circular support tube 31 and the square tube 2. The diameter of the filling plate 42 is matched with the inner wall diameter of the circular support tube 31. The supporting effect of the support component 3 is further improved through the auxiliary support component 4. The first filling plate 41, the circular filling plate 42 and the circular filling plate 42 are filled into the interior of the support component 3 to prevent the support component 3 from being deformed due to excessive force. Since the first filling plate 41, the circular filling plate 42 and the second filling plate 43 are all made of polyurethane rubber, since PU rubber has excellent wear resistance, tear resistance and impact resistance, the supporting effect of the support component 3 can be further improved.

[0031] The above solution also has the problem of getting stuck due to large friction when inserting the first filling plate 41, the circular filling plate 42 and the second filling plate 43. Figure 4As shown: In this solution, the first filling plate 41, the circular filling plate 42 and the second filling plate 43 are coated with a lubricating coating. The rubber lubricating coating generally refers to a coating with a rubber material coated on the surface to provide friction reduction and lubrication.

[0032] Working principle:

[0033] like Figure 1-4 As shown, first, the first filling plate 41 is inserted into the vertical gap between the circular support tube 31 and the square tube 2, and then the circular filling plate 42 is inserted into the circular support tube 31, and further, the second filling plate 43 is inserted into the gap between the second arc support plate 33 and the square tube 2. At this time, when the square tube 2 is subjected to vertical pressure, under the action of the first arc support plate 32, the vertical extrusion force is distributed to the circular support tube 31 and the second arc support plate 33, and the extrusion force is reduced by cooperating and supporting between multiple components. When the square tube 2 is subjected to lateral extrusion force, under the action of the second arc support plate 33, the pressure is transferred to the first arc support plate 32 and the circular support tube 31, and support is provided by cooperating between multiple components. At this time, the supporting effect of the support component 3 is further improved by the auxiliary support component 4 to prevent the support component 3 from being deformed due to excessive force.
