Description

Technical Field

[0001] This utility model relates to the field of door leaf profile technology, specifically a novel corner fitting for door leaves. Background Technology

[0002] Corner brackets are hardware widely used for connecting the corners of aluminum alloy doors and windows. Currently, aluminum corner brackets are commonly used for assembling aluminum alloy profiles. The aluminum corner brackets are first inserted into the profile cavity and then assembled using a corner bracket extrusion tool to complete their function.

[0003] A search revealed a novel aluminum alloy profile corner insert (CN204663332U), comprising a first corner segment, a second corner segment, a first concave arc groove, a second concave arc groove, a first locking block, a second locking block, and connecting bolts. The first and second corner segments are integral structures perpendicular to each other. The first corner segment has a first concave arc groove for fitting the first locking block, and the second corner segment has a first concave arc groove for fitting the second locking block. The first and second locking blocks are arranged in a symmetrical angular distribution. Bolt holes are provided on both the first and second locking blocks. The two ends of the connecting bolts pass through the bolt holes of the first and second locking blocks respectively, connecting the first and second locking blocks together.

[0004] The implementation of this technical solution has at least the following drawbacks: While this utility model can improve the stability of the corner segment connection, the need to pre-fix the corner components with bolts is too cumbersome, and the requirement to cut the two corner segments at corresponding bevels to ensure the aesthetics of the plug-in assembly greatly increases the workload of the assembly workers, necessitating improvement. Therefore, we propose a new type of door leaf corner connector. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of corner fitting for door panels, which solves the problems mentioned in the background art, such as the cumbersome process of pre-fixing the corner fittings with bolts, and the need to cut the two corner segments into corresponding bevels to ensure the aesthetics of the plug-in assembly, which greatly increases the workload of the workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel corner assembly insert for a door panel, comprising two corner assemblies arranged symmetrically. A first corner segment is fitted onto the outer side of the upper corner assembly, and a second corner segment is fitted onto the outer side of the lower corner assembly. Each corner assembly has a through groove on both sides, with a first arc-shaped block within the inner cavity of the through groove. A push rod is threaded through the center of the corner assembly, and wedge-shaped blocks are fixedly installed on both sides of the push rod. A positioning frame is provided on one side of the corner assembly, with a limit plate welded to the inner cavity of the positioning frame, and a second arc-shaped block fixedly installed on the outer side of the limit plate.

[0007] By adopting the above technical solution, the positions of the two corner pieces can be limited by the limiting plate on the positioning frame, avoiding the trouble of pre-fixing the corner pieces with bolts. During the movement of the positioning frame, the first arc-shaped block drives the clamping strip to abut against the inner walls of the first and second corner segments respectively, thereby achieving the connection limitation between the corner pieces and the first and second corner segments. After the positioning frame, the first and second corner segments are moved into place, the corner pieces are effectively covered, thus ensuring the aesthetics of the connection between the first and second corner segments. Moreover, it eliminates the need for workers to cut the two corner segments into corresponding bevels, thereby improving the assembly efficiency of the first and second corner segments.

[0008] Optionally, a clamping strip is fixedly installed on the outer side of the first arc-shaped block, and the length of the clamping strip is greater than the length of the through groove.

[0009] By adopting the above technical solution and setting the clamping strip, the first arc-shaped block is prevented from coming out of the through groove.

[0010] Optionally, the size of the first arc-shaped block is adapted to the size of the through groove, and the first arc-shaped block is movably connected to the through groove.

[0011] By adopting the above technical solution and setting the through groove, the stability of the first arc-shaped block is ensured.

[0012] Optionally, the dimensions of the first set of corner segments are the same as the dimensions of the second set of corner segments.

[0013] By adopting the above technical solution, the aesthetics of the assembly interface are ensured by making the dimensions of the first set of corner segments and the second set of corner segments consistent.

[0014] Optionally, the wedge blocks are symmetrically arranged, and the inclined surface of the wedge blocks is in contact with the arc surface of the first arc block.

[0015] By adopting the above technical solution and setting the wedge block, the first arc-shaped block can be pushed.

[0016] Optionally, the inner side of the limiting plate is fitted with the extension of the corner assembly.

[0017] By adopting the above technical solution and setting the limiting plate, the two corner pieces can be limited.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application, through the setting of a first set of corner segments, a second set of corner segments, corner components, a push rod, a wedge block, and a second arc block, can not only limit the position of the two corner components in cooperation with the limiting plate on the positioning frame, avoiding the trouble of workers needing to pre-fix the corner components with bolts, but also, during the movement of the positioning frame, the first arc block drives the clamping strip to abut against the inner walls of the first and second set of corner segments respectively, thereby achieving the connection limitation between the corner components and the first and second set of corner segments. Furthermore, after the positioning frame, the first set of corner segments, and the second set of corner segments have been moved into place, the corner components can be effectively covered, thus ensuring the aesthetics of the connection between the first and second set of corner segments. Moreover, it eliminates the trouble of workers cutting the two set of corner segments into corresponding bevels, thereby improving the assembly efficiency of the first and second set of corner segments.

[0021] Please see Figure 1-3This utility model provides a technical solution: a novel corner assembly insert for a door panel, comprising two corner assemblies 12 arranged symmetrically. A first corner segment 1 is fitted onto the outer side of the upper corner assembly 12, and a second corner segment 11 is fitted onto the outer side of the lower corner assembly 12. Both sides of each corner assembly 12 have through grooves 21, and the inner cavity of each groove 21 contains a first arc-shaped block 2. A push rod 23 is threaded through the center of each corner assembly 12, and wedge-shaped blocks 24 are fixedly installed on both sides of the push rod 23. A positioning frame 3 is provided on one side of each corner assembly 12. A limiting plate 4 is welded into the inner cavity. A second arc-shaped block 5 is fixedly installed on the outer side of the limiting plate 4. The size of the first set of corner segments 1 is the same as that of the second set of corner segments 11. By ensuring that the size of the first set of corner segments 1 and the second set of corner segments 11 is consistent, the aesthetics of the assembly interface are guaranteed. Wedge blocks 24 are symmetrically arranged, and the inclined surface of the wedge blocks 24 is in contact with the arc surface of the first arc-shaped block 2. By setting the wedge blocks 24, the first arc-shaped block 2 can be pushed. The inner side of the limiting plate 4 is in contact with the extension section of the corner assembly 12. By setting the limiting plate 4, the two corner assemblies 12 can be limited.

[0022] A clamping strip 22 is fixedly installed on the outer side of the first arc-shaped block 2, and the length of the clamping strip 22 is greater than the length of the through groove 21. By setting the clamping strip 22, the first arc-shaped block 2 is prevented from coming out of the through groove 21.

[0023] The size of the first arc-shaped block 2 is adapted to the size of the through groove 21, and the first arc-shaped block 2 is movably connected to the through groove 21. The stability of the first arc-shaped block 2 is ensured by the setting of the through groove 21.

[0024] During assembly, first insert the two corner pieces 12 into the first corner segment 1 and the second corner segment 11 respectively, then abut the lower ends of the corner pieces 12 together. Next, push the positioning frame 3 upwards along the lower ends of the corner pieces 12. The positioning frame 3, with the cooperation of the limiting plate 4, can limit the position of the two corner pieces 12, avoiding the hassle of pre-fixing the corner pieces 12 with bolts. Simultaneously, during the pushing process of the positioning frame 3, the second arc-shaped block 5 on the limiting plate 4 will push the push rod 23, causing the push rod 23 to move outwards. The wedge-shaped block 24 on the push rod 23 will then push the first arc-shaped block 5 upwards. The first arc-shaped block 2 is pushed, which causes the first arc-shaped block 2 to drive the pressing strip 22 to abut against the inner walls of the first set of corner segments 1 and the second set of corner segments 11 respectively, thereby achieving the connection limitation between the corner assembly 12 and the first set of corner segments 1 and the second set of corner segments 11. At the same time, after the positioning frame 3, the first set of corner segments 1 and the second set of corner segments 11 are pushed into place, the corner assembly 12 is effectively covered, thereby ensuring the aesthetics of the connection between the first set of corner segments 1 and the second set of corner segments 11. Moreover, it eliminates the need for workers to cut the two sets of corner segments into corresponding bevels, thereby improving the assembly efficiency of the first set of corner segments 1 and the second set of corner segments 11.
