Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and more specifically, to an aluminum profile corner connection structure. Background Technology

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Due to their characteristics such as light weight, corrosion resistance, excellent machinability, and high recyclability, the sales volume of aluminum profiles has been increasing year by year. In the construction field, they are used as door and window curtain wall frames and decorative components to achieve both structural stability and aesthetics. When assembling aluminum profiles, connecting structures are needed at the corners to connect and fix the various aluminum profiles.

[0003] One type of aluminum profile corner structure connects and fixes aluminum profiles in three directions (i.e., X-axis, Y-axis, and Z-axis). The existing connection structure involves setting a corner piece in two adjacent directions. The corner piece is right-angled, with its two right-angled sides abutting against the aluminum profile. Then, the corner piece is fixed to the aluminum profile with bolts, thus connecting the various aluminum profiles at the corner. For corners at the bottom, it is also necessary to connect them to the base.

[0004] However, when connecting two aluminum profiles and corner pieces, the threaded holes on the aluminum profiles and corner pieces must first be aligned before they can be connected with bolts. But in the actual assembly process, each aluminum profile and corner piece can only be fixed to the other with bolts one by one. That is, after one aluminum profile and corner piece are spliced ​​together and fixed with bolts, the tool is put down, and then the next aluminum profile and corner piece are spliced ​​together, and then the tool is picked up and fixed to the other with bolts. Finally, each aluminum profile is fixed to the base. Therefore, the assembly is inconvenient and the overall assembly efficiency is low. Utility Model Content

[0005] Therefore, in order to solve the problems of inconvenient assembly at the bottom corner and low overall assembly efficiency, this utility model provides an aluminum profile corner connection structure, the specific technical solution of which is as follows:

[0006] A corner connection structure for aluminum profiles includes a Z-axis aluminum profile, an X-axis aluminum profile, a Y-axis aluminum profile, a base, and a pair of corner pieces. The Z-axis, X-axis, and Y-axis aluminum profiles are all mounted on the top of the base. The top of the base has an insertion groove for the bottom end of the Z-axis aluminum profile to be inserted. Each outer wall of the Z-axis aluminum profile, each outer wall of the X-axis aluminum profile, and each outer wall of the Y-axis aluminum profile have a locking groove. One corner piece is located at the joint corner between the Z-axis and X-axis aluminum profiles, and the other corner piece is located at the joint between the Z-axis and X-axis aluminum profiles. At the splicing corners between the Y-axis aluminum profiles; each corner piece is provided with a first locking strip at the position corresponding to the Z-axis, X-axis, and Y-axis aluminum profiles, and the first locking strip slides and engages with the corresponding locking groove; each top of the base is provided with a second locking strip at the position corresponding to the X-axis and Y-axis aluminum profiles, and the second locking strip slides and engages with the corresponding locking groove; the corner piece is connected to the Z-axis, X-axis, and Y-axis aluminum profiles by a first fastener, and the base is connected to the X-axis and Y-axis aluminum profiles by a second fastener.

[0007] By adopting the above technical solution, during assembly, firstly, the bottom end of the Z-axis aluminum profile is inserted into the insertion slot. Then, the two corner pieces are slidably engaged in the corresponding first locking strips into the locking slots on adjacent sides of the Z-axis aluminum profile. Next, the X-axis and Y-axis aluminum profiles are inserted between the corner pieces and the base plate, respectively, so that the first locking strip on the corner piece and the second locking strip on the base plate are slidably engaged in the locking slots in the X-axis and Y-axis aluminum profiles, until the bottom end of the Z-axis aluminum profile abuts against the ends of the X-axis and Y-axis aluminum profiles; at this point, This assembly process allows for initial positioning and assembly of the Z-axis aluminum profile, X-axis aluminum profile, Y-axis aluminum profile, base, and a pair of corner pieces. The corner pieces are first connected to the Z-axis, X-axis, and Y-axis aluminum profiles using a first fastener, and then the base is connected to the X-axis and Y-axis aluminum profiles using a second fastener. This assembly process allows for initial positioning and assembly of the Z-axis, X-axis, and Y-axis aluminum profiles, base, and a pair of corner pieces, followed by fixation using the first and second fasteners. This significantly improves assembly convenience and efficiency.

[0008] Furthermore, a limiting member is installed in the slot of the Z-axis aluminum profile, and the limiting member abuts against the bottom end of the first slotting strip that is engaged in the slot of the Z-axis aluminum profile.

[0009] Furthermore, the limiting component includes a limiting screw, which is threaded onto the bottom of the slot of the Z-axis aluminum profile.

[0010] Furthermore, the limiting component includes a stop block, which is fixedly installed at the bottom of the slot of the Z-axis aluminum profile.

[0011] Furthermore, the first locking strip includes a sliding portion and a pair of locking portions. The sliding portion is fixedly installed on the top of the base, and the two locking portions are respectively disposed on both sides of the sliding portion; the locking groove is adapted to the shape of the first locking strip.

[0012] Furthermore, the first fastener includes a first fastening screw, which passes through the corner piece and is threaded onto the X-axis aluminum profile, the Y-axis aluminum profile, or the Z-axis aluminum profile.

[0013] Furthermore, the corner piece includes a pair of right-angle plates and a reinforcing rib. The two right-angle plates are connected to each other and form a right angle. The first locking strip is provided on the back of both right-angle plates. The reinforcing rib is connected to both right-angle plates.

[0014] Furthermore, the second fastener includes a second fastening screw, which passes through the base and is threaded onto the X-axis aluminum profile or the Y-axis aluminum profile.

[0015] Furthermore, the base is detachably equipped with support feet located between the X-axis aluminum profile and the Y-axis aluminum profile.

[0016] Furthermore, the support foot includes a support base and a threaded rod mounted on the support base. The threaded rod passes through the base and a pair of fastening nuts are threaded onto the threaded rod. The two fastening nuts abut against both sides of the base, respectively.

[0030] Example 1

[0031] like Figure 1 and Figure 2As shown, an aluminum profile corner connection structure in one embodiment of this utility model includes a Z-axis aluminum profile 1, an X-axis aluminum profile 2, a Y-axis aluminum profile 3, a base 4, and a pair of corner pieces 5. The Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3 are all mounted on the top of the base 4. The top of the base 4 has an insertion groove 41 for inserting the bottom end of the Z-axis aluminum profile 1, thereby achieving initial positioning of the Z-axis aluminum profile 1. Each outer wall of the Z-axis aluminum profile 1, each outer wall of the X-axis aluminum profile 2, and each outer wall of the Y-axis aluminum profile 3 has a locking groove 6. One corner piece 5 is located at the splicing corner between the Z-axis aluminum profile 1 and the X-axis aluminum profile 2, and the other corner piece 5 is located at the splicing corner between the Z-axis aluminum profile 1 and the Y-axis aluminum profile 3. The corner piece 5 corresponds to the Z-axis... A first locking strip 51 is fixedly installed at the positions of aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3. The first locking strip 51 slides and engages with the corresponding locking groove 6, thereby allowing the corner piece 5 to be initially positioned with the Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3. A second locking strip 42 is fixedly installed at the top of the base 4 at the positions corresponding to the X-axis aluminum profile 2 and Y-axis aluminum profile 3. The second locking strip 42 slides and engages with the corresponding locking groove 6, thereby allowing the corner piece 5 to be initially positioned with the X-axis aluminum profile 2 and Y-axis aluminum profile 3. The corner piece 5 is connected to the Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3 by a first fastener 52, and the base 4 is connected to the X-axis aluminum profile 2 and Y-axis aluminum profile 3 by a second fastener 43.

[0032] During assembly, first insert the bottom end of the Z-axis aluminum profile 1 into the insertion slot 41. Then, slide and engage the two corner pieces 5 into the corresponding first locking strips 51 on the adjacent sides of the Z-axis aluminum profile 1. Next, insert the X-axis aluminum profile 2 and Y-axis aluminum profile 3 between the corner pieces 5 and the base plate, so that the first locking strips 51 on the corner pieces 5 and the second locking strips 42 on the base plate slide and engage into the locking slots in the X-axis aluminum profile 2 and Y-axis aluminum profile 3, respectively, until the Z-axis aluminum profile 1... The bottom end of the base 4 abuts against the ends of the X-axis aluminum profile 2 and the Y-axis aluminum profile 3; at this point, the initial positioning and assembly of the Z-axis aluminum profile 1, X-axis aluminum profile 2, Y-axis aluminum profile 3, base 4, and a pair of corner pieces 5 can be achieved; finally, the corner pieces 5 are connected to the Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3 by the first fastener 52, and then the base 4 is connected to the X-axis aluminum profile 2 and Y-axis aluminum profile 3 by the second fastener 43; the above process greatly improves the convenience of assembly and increases the assembly efficiency.

[0033] like Figure 2 and Figure 3As shown, a limiting component is installed in the slot 6 of the Z-axis aluminum profile 1. The limiting component abuts against the bottom end of the first locking strip 51, which is locked in the slot 6 of the Z-axis aluminum profile 1. The limiting component includes a limiting screw 7, which is threaded onto the bottom of the slot 6 of the Z-axis aluminum profile 1. Thus, when the first locking strip 51 in the corner piece 5 is slid into the slot 6 of the Z-axis aluminum profile 1, until it abuts against the limiting screw 7, it means that the distance between the corner piece 5 and the base 4 is sufficient for the X-axis aluminum profile 2 or the Y-axis aluminum profile 3 to pass through. The limiting screw 7 allows for easy adjustment of the position of the limiting component.

[0034] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the first locking strip 51 includes a sliding part 511 and a pair of locking parts 512. The sliding part 511 is fixedly installed on the top of the base 4, and the two locking parts 512 are respectively arranged on both sides of the sliding part 511. The locking groove 6 is adapted to the shape of the first locking strip 51, so that the first locking strip 51 can slide stably in the locking groove 6. The second locking strip 42 has the same structure as the first locking strip 51, and will not be described in detail here.

[0035] like Figure 2 and Figure 4 As shown, the first fastener 52 includes a first fastening screw, which passes through the corner piece 5 and is threaded onto the X-axis aluminum profile 2, Y-axis aluminum profile 3, or Z-axis aluminum profile 1, thereby achieving a stable detachable connection between the corner piece 5 and the X-axis aluminum profile 2, Y-axis aluminum profile 3, or Z-axis aluminum profile 1.

[0036] The second fastener 43 includes a second fastening screw, which passes through the base 4 and is threaded onto the X-axis aluminum profile 2, Y-axis aluminum profile 3, or Z-axis aluminum profile 1, thereby achieving a stable detachable connection between the base 4 and the X-axis aluminum profile 2, Y-axis aluminum profile 3, or Z-axis aluminum profile 1; the base 4 is provided with a countersunk groove 44 at the head position corresponding to the second fastening screw.

[0037] like Figure 1 As shown, the corner piece 5 includes a pair of right-angle plates 53 and a reinforcing rib 54. The two right-angle plates 53 are connected to each other and form a right angle. The back of each of the two right-angle plates 53 is provided with a first locking strip 51. The reinforcing rib 54 is connected to both right-angle plates 53. The corner piece 5 has high overall stability.

[0038] like Figure 1 and Figure 4As shown, the base 4 is located between the X-axis aluminum profile 2 and the Y-axis aluminum profile 3 and is detachably equipped with a support foot 9. The support foot 9 includes a support seat 91 and a threaded rod 92 installed on the support seat 91. The threaded rod 92 passes through the base 4 and a pair of fastening nuts 93 are threaded on the threaded rod 92. The two fastening nuts 93 abut against the two sides of the base 4 respectively. Thus, the support foot 9 and the base 4 can be detachably connected.

[0039] The implementation principle of Example 1 is as follows: During assembly, firstly, the bottom end of the Z-axis aluminum profile 1 is inserted into the insertion slot 41. Then, the two corner pieces 5 are slidably engaged in the corresponding first locking strips 51 into the locking slots on the adjacent sides of the Z-axis aluminum profile 1. Next, the X-axis aluminum profile 2 and the Y-axis aluminum profile 3 are inserted between the corner pieces 5 and the base plate, respectively, so that the first locking strip 51 on the corner piece 5 and the second locking strip 42 on the base plate are slidably engaged in the locking slots in the X-axis aluminum profile 2 and the Y-axis aluminum profile 3, until the Z-axis aluminum profile 1... The bottom end abuts against the ends of the X-axis aluminum profile 2 and the Y-axis aluminum profile 3; at this point, the initial positioning assembly of the Z-axis aluminum profile 1, X-axis aluminum profile 2, Y-axis aluminum profile 3, base 4, and a pair of corner pieces 5 can be achieved; finally, the corner pieces 5 are connected to the Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3 by the first fastening screw, then the corner pieces 5, Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3 are laid on their sides, and finally the base 4 is connected to the Z-axis aluminum profile 1, X-axis aluminum profile 2, and Y-axis aluminum profile 3 by the second fastening screw.

[0040] Example 2

[0041] like Figure 5 and Figure 6 As shown, the difference from Embodiment 1 is that the limiting member includes a stop 8, which is fixedly installed at the bottom of the slot 6 of the Z-axis aluminum profile 1; thus, when the first slot strip 51 in the corner piece 5 is slid into the slot 6 of the Z-axis aluminum profile 1, until it abuts against the stop 8, it means that the distance between the corner piece 5 and the base 4 is sufficient for the X-axis aluminum profile 2 or the Y-axis aluminum profile 3 to pass through.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
