Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to a heat-insulating aluminum profile and its edge-pressing equipment. Background Technology

[0002] Thermally insulated aluminum profiles typically consist of an aluminum profile frame and thermal insulation strips connected to the frame. The thermal insulation strips are generally made of non-metallic materials, such as PVC or polyurethane. The main characteristic of the thermal insulation strips is their low thermal conductivity. Their function is to prevent heat from being transferred out through the connection points of the aluminum profiles. However, ensuring the reliability of the connection between the thermal insulation strips and the aluminum profiles has become an urgent problem to be solved.

[0003] In existing technologies, the fixing of thermal insulation strips often involves pre-leaving suitable grooves or channels, such as dovetail grooves, during the extrusion process of aluminum profiles. The connection between the two aluminum profiles is achieved by inserting the thermal insulation strip into the dovetail groove. In order to improve the tightness of the connection, existing technologies also use adhesives or double-sided tape to bond the thermal insulation strip to the aluminum profile. However, the reliability and connection efficiency of the above connection methods are difficult to reach the ideal level. Utility Model Content

[0004] In view of at least one of the above technical problems, the present invention provides a heat-insulating aluminum profile and its pressing device, which adopts structural improvements to improve the connection reliability and connection efficiency of the heat insulation strip.

[0005] According to a first aspect of the present invention, a heat-insulating aluminum profile is provided, comprising: an aluminum profile outer frame formed by extrusion of aluminum alloy material, wherein the two ends of the inner side of the aluminum profile outer frame have a first engaging structure;

[0006] The inner frame of the aluminum profile is formed by extrusion of aluminum alloy material and is disposed opposite to the outer frame of the aluminum profile. The inner wall of the inner frame of the aluminum profile has two second engaging structures corresponding to the first engaging structure.

[0007] There are two heat insulation strips, and one end of each heat insulation strip is engaged in the first engaging structure, and the other end is engaged in the second engaging structure.

[0008] The first and second locking structures each include a first locking arm and a second locking arm that extend toward the inner side of the outer frame or the inner frame of the aluminum profile and are spaced apart. The first locking arm and the second locking arm form a locking groove for locking the end of the heat insulation strip. The second locking arm is configured to move a set distance toward the first locking arm at its free end under the action of an external force, so that the locking groove forms a constricted structure that compresses the heat insulation strip.

[0009] In some embodiments of this utility model, the heat insulation strip has clips at both ends, and the two clips have a dovetail structure.

[0010] In some embodiments of this utility model, the inner wall of the first card arm facing the second card arm is arranged parallel to the side wall of the card head.

[0011] In some embodiments of this utility model, the bottom of the second card arm located within the card slot has an arc-shaped bending groove.

[0012] In some embodiments of this utility model, the width of the second card arm is gradually widened from the direction close to the bending groove to the direction away from the bending groove.

[0013] In some embodiments of this utility model, the free end of the second card arm has a triangularly arranged pressing part on the side away from the card slot, and the pressing part is used to resist external forces.

[0014] In some embodiments of this utility model, the free end of the second card arm near the card slot also has a pressing part that protrudes in a direction away from the pressing part, the pressing part being used to press with the heat insulation strip to form a sealing surface.

[0015] In some embodiments of this utility model, the two clips of the heat insulation strip are arranged opposite to each other and collinearly. The heat insulation strip also includes an inclined section connected to the inner ends of the two clips respectively and a straight section whose two ends are connected to the two inclined sections respectively. The straight section is arranged parallel to the line connecting the two clips. The end of the pressing part is located outside the straight section in the initial position.

[0016] In some embodiments of this utility model, the aluminum profile outer frame also has a hollow cavity inside.

[0017] According to a second aspect of the present invention, a pressing device for a heat-insulating aluminum profile as described above is provided, comprising:

[0018] Support wheels, wherein there are multiple support wheels arranged in a straight line, the support wheels are used to roll and support the outer wall of the aluminum profile frame;

[0019] The pressure wheel is arranged radially perpendicular to the heat insulation strip. The width of the pressure wheel is adapted to the distance between the two pressing parts on the first and second engaging structures. The pressure wheel presses the pressing part in a direction perpendicular to the heat insulation strip.

[0020] The beneficial effects of this utility model are as follows: By setting a first engaging structure and a second engaging structure on the outer frame and inner frame of the aluminum profile respectively, a groove is formed with the heat insulation strip for installation. Under the action of external force, the groove forms a constriction structure that compresses the heat insulation strip, making the heat insulation strip firmly installed. Compared with the prior art, it avoids the use of adhesives or double-sided tape for connection, thus improving the reliability and efficiency of the heat insulation strip connection.

[0034] Example 1

[0035] like Figures 1 to 4 The heat-insulating aluminum profile shown includes: an outer aluminum frame 1, formed by extrusion of aluminum alloy material, with first engaging structures 11 at both ends of the inner side of the outer aluminum frame 1; and an inner aluminum frame 2, formed by extrusion of aluminum alloy material and disposed opposite to the outer aluminum frame 1, with two second engaging structures 21 on the inner wall of the inner aluminum frame 2 corresponding to the first engaging structures 11. Both the outer aluminum frame 1 and the inner aluminum frame 2 are formed by extrusion of aluminum alloy material, possessing high strength and durability. Figure 4As shown, there are two heat insulation strips 3, with one end of each strip engaged in the first engaging structure 11 and the other end engaged in the second engaging structure 21. The material of the heat insulation strips 3 can be engineering plastics or composite materials with excellent thermal conductivity, selected according to actual production needs. Both the first engaging structure 11 and the second engaging structure 21 include a first locking arm 111 and a second locking arm 112 extending towards the inner side of the aluminum profile outer frame 1 or the inner side of the aluminum profile inner frame 2 and spaced apart. The first locking arm 111 and the second locking arm 112 form a groove 113 for engaging the end of the heat insulation strip 3. The second locking arm 112 is configured such that its free end moves a set distance towards the first locking arm 111 under external force, causing the groove 113 to form a constricted structure that compresses the heat insulation strip 3. It should be noted that the inner side of the aluminum profile outer frame 1 and the inner side of the aluminum profile inner frame 2 refer to the inner side of the integrated structure formed by the aluminum profile inner frame 2, the aluminum profile outer frame 1, and the heat insulation strip 3. Figure 3 As shown, the free end of the second clamping arm 112 has a certain elasticity and can move a certain distance towards the first clamping arm 111 under the action of external force, forming a compression and contraction structure on the end of the heat insulation strip 3. During installation, one end of the heat insulation strip 3 is inserted into the first engaging structure 11, and the other end is inserted into the second engaging structure 21 of the aluminum profile inner frame 2. When an external force is applied, the free end of the second clamping arm 112 moves towards the first clamping arm 111, causing the clamping groove 113 to contract and compress the heat insulation strip 3.

[0036] In the above embodiments, by setting a first engaging structure 11 and a second engaging structure 21 on the outer frame 1 and the inner frame 2 of the aluminum profile respectively, a mounting groove 113 is formed with the heat insulation strip 3, and the groove 113 forms a constriction structure that compresses the heat insulation strip 3 under the action of external force, so that the heat insulation strip 3 is firmly installed; compared with the prior art, the use of adhesives or double-sided tape for connection is avoided, and the reliability and efficiency of the connection of the heat insulation strip 3 are improved.

[0037] Optionally, the specific structure of the thermal insulation strip 3 is as follows: Figure 4 As shown, the thermal insulation strip 3 has locking heads 31 at both ends, and the two locking heads 31 have a dovetail structure. It should be noted that the dovetail structure means that each locking head 31 has a trapezoidal shape with a gradually narrowing width. Both ends have dovetail structures, which ensures that the thermal insulation strip 3 can simultaneously match the first locking structure 11 and the second locking structure 21 on both sides of the aluminum profile outer frame 1 and the aluminum profile inner frame 2. This setting optimizes the self-locking fixation, tight sealing effect and simple installation method, which not only improves the overall performance, but also enhances the stability and service life of the product.

[0038] In this embodiment of the utility model, in order to further ensure the stability of the product, such as Figure 2As shown, the inner wall of the first clamping arm 111 facing the second clamping arm 112 is parallel to the side wall of the clamping head 31. The side wall of the clamping head 31 is straight and consistent with the inner wall of the first clamping arm 111 in the parallel direction, ensuring that a stable linear contact can be formed after the heat insulation strip 3 is inserted into the clamping slot 113. This arrangement not only ensures smooth insertion during installation but also improves the stability after the clamping is completed.

[0039] In this embodiment of the invention, to enhance the snap-fit ​​performance of the product, please continue to refer to... Figure 2 The second clamping arm 112 has an arc-shaped bending groove 112a at its bottom within the clamping slot 113. The bending groove 112a provides the second clamping arm 112 with a certain degree of elasticity and a buffer area, allowing for more flexible movement. The arc-shaped surface of the bending groove 112a, together with the bottom structure of the heat insulation strip 3 clamping head 31, provides a better fit.

[0040] Furthermore, in terms of structural optimization, such as Figure 2 As shown, the width of the second clamping arm 112 gradually widens from near the bending groove 112a to away from the bending groove 112a. The portion of the second clamping arm 112 near the bending groove 112a is narrower, while the portion away from the bending groove 112a gradually increases in width. This configuration is adopted to accommodate subsequent processing requirements.

[0041] In the embodiment of the present utility model, as Figure 2 and Figure 3 As shown, the free end of the second locking arm 112, away from the slot 113, has a triangularly arranged pressing part 112b, which is used to resist external forces. It should be noted that the triangular geometry provides a stable force-bearing surface, making the product less prone to slippage when external forces are applied. When subjected to external forces, the free end of the second locking arm 112 deforms towards the slot 113, and the triangularly arranged pressing part 112b tightly presses against the heat insulation strip 3, ensuring the stability of the product during use.

[0042] Based on the above embodiments, in order to better cooperate with the heat insulation strip 3 to achieve a sealing effect, please continue to refer to... Figure 2 The free end of the second locking arm 112, near the locking groove 113, also has a pressing part 112c that protrudes in a direction away from the pressing part 112b. The pressing part 112c is used to press with the heat insulation strip 3 to form a sealing surface. Figure 2 The extrusion part 112c shown is arc-shaped, but its protrusion shape can also be linear, depending on the shape of the clamping head 31 of the heat insulation strip 3, to ensure a tight fit between the two. The extrusion part 112c at the free end of the second clamping arm 112 achieves the dual goals of enhancing the product's clamping firmness and sealing performance through its protrusion design.

[0043] In embodiments of this utility model, the heat insulation strip 3, in conjunction with the above-described specific structure, is as follows: Figure 4 As shown, the two clips 31 of the heat insulation strip 3 are arranged opposite each other and collinearly. The two clips 31 are arranged opposite each other in space and coincide with the same axis, ensuring the overall symmetry of the heat insulation strip 3 and helping to form a uniform connection force with the slot 113. The heat insulation strip 3 also includes inclined sections 32 connected to the inner ends of the two clips 31 respectively, and straight sections 33 connected to the two inclined sections 32 at both ends respectively. The straight sections 33 are arranged parallel to the line connecting the two clips 31. The inclined sections 32 are connected to the inner ends of the two clips 31 respectively, forming a transition with the straight sections 33. The ends of the two inclined sections 32 are connected through the straight sections 33. The straight sections 33 are parallel to the line connecting the two clips 31, so that the geometry of the heat insulation strip 3 has a certain degree of flexible transition effect. The end of the pressing part 112b is located outside the straight section 33 in the initial position. That is, when the heat insulation strip 3 is not completely fixed, the pressing part 112b and the straight section 33 maintain a certain distance, leaving space for subsequent locking and sealing operations. This design achieves both ease of installation and structural stability for the product.

[0044] Example 2

[0045] This embodiment also proposes a heat-insulating aluminum profile. The second embodiment is a further improvement based on the first embodiment. In the second embodiment of this utility model, the structure of the outer frame 1 of the aluminum profile is improved. The connection relationship of the inner frame 2 and the heat insulation strip 3 of the remaining aluminum profile is the same as that of the first embodiment, and will not be described again here. In the second embodiment of this utility model, the outer frame 1 of the aluminum profile also has a hollow cavity 12 inside. Figure 5 As shown, the hollow cavity 12 is located inside the aluminum profile outer frame 1, and is formed in one step through the extrusion molding process of the aluminum profile, requiring no additional processing. Figure 5 As shown, the hollow cavity 12 is reinforced with aluminum profiles. Alternatively, the hollow cavity 12 can extend through the entire length of the outer frame, depending on actual needs. The shape and structure of the hollow cavity 12 are unrestricted. The hollow cavity 12 reduces the material usage of the aluminum profile outer frame 1, significantly reducing the self-weight of the aluminum profile while maintaining overall strength. Furthermore, it should be noted that a static air layer can be formed inside the hollow cavity 12. Air has a low thermal conductivity, thus significantly improving the thermal insulation performance of the aluminum profile. Especially when used in conjunction with the thermal insulation strip 3, the presence of the hollow cavity 12 further enhances the thermal insulation effect of the profile. The hollow cavity 12 of the aluminum profile outer frame 1 achieves both lightweighting and improved thermal insulation performance.

[0046] Example 3

[0047] In this embodiment of the utility model, a method such as... is also provided. Figures 6 to 8 The edge-pressing equipment shown is used to press the edges of the heat-insulating aluminum profiles in Examples 1 and 2, and includes: Figure 6 The support wheels 10 shown are numerous and arranged in a straight line to ensure that the equipment can evenly support the entire length of the aluminum profile frame 1. The support wheels 10 are used to roll and support the outer wall of the aluminum profile frame 1, ensuring the aluminum profile remains stable during the pressing operation and preventing swaying or positional displacement. Figure 8 As shown, the radial direction of the pressing wheel 20 is perpendicular to the heat insulation strip 3, and the width of the pressing wheel 20 is adapted to the distance between the two pressing portions 112b on the first engaging structure 11 and the second engaging structure 21. The pressing wheel 20 presses the pressing portions 112b in a direction perpendicular to the heat insulation strip 3. Figure 7 As shown, the pressing wheel has a groove, the length of which matches the length of the straight section. This design reduces the impact on the heat insulation strip during pressing. During operation, the support wheel 10 contacts the outer wall of the aluminum profile frame 1, and the radial direction of the pressing wheel 20 is perpendicular to the heat insulation strip 3. When the equipment starts, the pressing wheel 20 moves along a preset trajectory and aligns with the two pressing portions 112b on the first engaging structure 11 and the second engaging structure 21. The pressing wheel 20 applies pressure in a direction perpendicular to the heat insulation strip 3, pushing the pressing portions 112b inward, causing the constricted structure of the slot 113 to clamp the heat insulation strip 3, completing the fixing and sealing operation of the heat insulation strip 3. This pressing equipment, through the coordinated cooperation of the support wheel 10 and the pressing wheel 20, not only ensures the firm engagement and sealing of the heat insulation strip 3 with the slot 113, but also significantly improves production efficiency and product quality.
