Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy window frame connectors, specifically a corner connector for a space divider. Background Technology

[0002] Aluminum alloy window frames have become the mainstream choice in the building door and window industry due to their advantages such as lightweight, corrosion resistance, and strong wind pressure resistance. The reliability of the connection and assembly precision of the window frame corners directly determine the overall structural stability, appearance flatness, and long-term performance of the window. As the core component for splicing the 45° beveled surface of the window frame into a 90° corner, the rationality of the design of the connector is the key to ensuring the long-term stability of the window frame after one-time assembly.

[0003] Traditional connectors are straight strips or non-L-shaped structures, which cannot accurately match the 90° shape of the window frame corner and the 45° splicing slope. During assembly, the relative position of the connector and the window frame needs to be repeatedly adjusted. Moreover, there is a lack of positioning structure that adapts to the inner cavity of the window frame. After the connector is inserted into the profile groove, it is easy to shift left and right or tilt forward and backward, which seriously affects the stability of the connector inserted into the window frame. To address this, we provide a corner connector for the spacer strip. Utility Model Content

[0004] The purpose of this invention is to provide a corner connector for a spacer bar in the middle, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner connector for a space divider, comprising a connector body, the connector body being suitable for a 45° bevel at the corner of an aluminum alloy window frame, the left side and top of the connector body being provided with several barbed bodies, the top of the left side of the connector body and the left side of the top of the top being provided with arc-shaped blocks, and the front and back of the connector body being provided with several anti-slip blocks.

[0006] Optionally, the connector body is L-shaped, and the connector body, barb body, arc block and anti-slip block are integrally formed by injection molding, and the anti-slip block is semi-circular in shape.

[0007] Optionally, the barb body on the left side and the barb body on the top of the connector body are evenly distributed along the length direction of the connector body, the distance between two adjacent barb bodies is 8-15mm, the height of the barb body is 1-2mm, and the tilt angle of the barb body is 30 degrees.

[0008] Optionally, the radius of the arc-shaped block is 2-5mm, and two arc-shaped blocks form a semicircle. The radius of the semicircle is adapted to the radius of the 90° corner of the inner cavity of the aluminum alloy window frame.

[0009] Optionally, a protrusion is installed on the bottom of the left side and the right side of the top of the connector body. The protrusion is integrally injection molded with the connector body, and the end of the protrusion away from the connector body has a smooth transition edge.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The L-shaped structure of the connector body of this utility model perfectly matches the 90° corner shape of the aluminum alloy window frame. The gap between the 45° beveled contact surface and the beveled surface of the window frame is small, eliminating the need for repeated position adjustments. The L-shaped structure of the connector body has a built-in 90° positioning reference, which can directly ensure the corner accuracy after the window frame is spliced ​​after insertion into the profile groove. By setting the barbed body, the stability of the connector body inserted into the aluminum alloy window frame is ensured. At the same time, by setting the anti-slip block, the friction of the connector body inserted into the aluminum alloy window frame is improved. The semi-circular anti-slip block can resist the deformation difference between the aluminum alloy and the connector, prevent the connector from sliding relative to the profile groove, and improve the stability of the connector inserted into the aluminum alloy window frame.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3A corner connector for a spacer strip includes a connector body 1. The connector body 1 is adapted to the 45° bevel at the corner joint of an aluminum alloy window frame. The connector body 1 directly fits the 45° bevel at the corner joint of the aluminum alloy window frame, realizing the 90° corner positioning and connection of two window frame sections. Several barbed bodies 2 are installed on the left side and top of the connector body 1. The barbed bodies 2 on the left side and the top of the connector body 1 are evenly distributed along the length direction of the connector body 1. The distance between two adjacent barbed bodies 2 is 10mm, and the height of the barbed bodies 2 is 1.5mm. The barb body 2 has a tilt angle of 30 degrees, allowing for smooth insertion and reverse self-locking. When inserted into the window frame profile groove, the 30° tilted barb body 2 deforms in the forward direction and then returns to its original position after insertion, tightly engaging with the inner wall of the profile groove to prevent the connector body 1 from shifting axially along the profile groove. Arc-shaped blocks 3 are installed on the top left side and the left side of the top left side of the connector body 1. The arc radius of the arc blocks 3 is 3mm. The two arc blocks 3 form a semicircle, the radius of which matches the radius of the 90° corner of the aluminum alloy window frame's inner cavity. The two arc blocks 3 form a complete semicircle, which... The 90° corner radius of the window frame's inner cavity is perfectly matched, creating a tight fit. Several anti-slip blocks 4 are installed on both the front and back of the connector body 1. The connector body 1 is L-shaped. The connector body 1, barbed body 2, arc-shaped block 3, and anti-slip blocks 4 are integrally molded by injection molding. The anti-slip blocks 4 are semi-circular in shape. The anti-slip blocks 4 increase the friction between the connector body 1 and the inner wall of the window frame profile groove. The semi-circular anti-slip blocks 4 increase the friction coefficient of the contact area, preventing the connector body 1 from rotating or sliding with the profile groove during installation. The semi-circular shape has no sharp edges, so it will not scratch the profile during insertion. The inner wall of the groove can also adapt to the slight unevenness of the inner wall of the profile groove, making the anti-slip effect more stable. The anti-slip blocks 4 on the front and back are arranged in a symmetrical array, which can evenly distribute the friction force and avoid the overall sliding caused by the failure of single-point anti-slip. The bottom of the left side and the right side of the top of the connector body 1 are both equipped with protrusions 5. The protrusions 5 are integrally injection molded with the connector body 1. The end of the protrusion 5 away from the connector body 1 has a smooth transition edge. The protrusion 5 can be used as an insertion guide head to reduce the resistance of insertion into the profile groove inlet. The connector body 1, barbed body 2, arc block 3, anti-slip block 4 and protrusion 5 are all made of modified PVC.

[0015] In use, take one connector body 1, align the two sides of the L-shaped connector body 1 with the 45° beveled profile grooves of the two window frames respectively, and then insert the protrusion 5 into the profile groove of the window frame first, so that the L-shaped corner of the connector body is aligned with the 90° corner to be formed in the window frame. At this time, the semicircle formed by the two arc blocks 3 fits the 90° corner wall of the inner cavity of the window frame. The anti-slip block 4 and the barb body 2 are in close contact with the inner wall of the profile groove. Start the special welding machine for aluminum alloy window frames, and weld the welding gun at the 45° beveled splice of the window frame.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
