Description

Technical Field

[0001] This utility model relates to an easy-to-install corner bracket with a frustum-shaped end. Background Technology

[0002] Automatic door and window frame assembly machines can efficiently and quickly assemble rectangular aluminum alloy door and window frames. However, the corner brackets used in these machines cannot be fixed by rivets, screws, or adhesives. Assembling aluminum alloy frames using these traditional corner brackets is too time-consuming, resulting in very low assembly efficiency. Therefore, corner brackets that require rivet, screw, or adhesive connections cannot be used in automatic frame assembly machines for assembling door and window frames. Thus, it is necessary to develop a new type of corner bracket for connecting aluminum alloy door and window frames to meet the needs of automatic door and window frame assembly machines. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic assembly machine for door and window frames that can efficiently and quickly complete the automatic assembly of aluminum alloy door and window frames, making the corners of the connected frames very strong, and the corners of the frame are connected with high strength and rigidity with easy-to-insert corner brackets in the shape of a frustum.

The bottom end of the vertical insert bar is provided with a lower frustum with a cone angle pointing downward. The right angle is provided with a trapezoidal groove that passes through the right angle along the front-back direction. The opening end of the trapezoidal groove is the upper base, and the bottom surface of the trapezoidal groove is the lower base.

[0005] The trapezoidal groove has a vertical elastic lever on its left side. The bottom end of the vertical elastic lever is connected to the vertical insert as a whole, and the top end of the vertical elastic lever is a free end that can spring open to the left.

[0006] The trapezoidal groove has a horizontal elastic lever on its right side. The right end of the horizontal elastic lever is connected to the horizontal insert bar as a whole, and the left end of the horizontal elastic lever is a free end that can spring upward.

[0007] The end of this utility model is a four-sided frustum-shaped easy-to-insert corner bracket, wherein the middle part of the right four-sided frustum and the right side of the horizontal insert are provided with an external through groove along the front-back direction, the middle part of the horizontal insert is provided with a central through hole along the front-back direction, and the right side of the horizontal insert is provided with a right through hole along the front-back direction.

[0008] The lower quadrangular truncated pyramid and the lower part of the vertical insert are provided with a lower through groove along the front-back direction, the middle part of the vertical insert is provided with a central through hole along the front-back direction, and the upper part of the vertical insert is provided with an upper through hole along the front-back direction.

[0009] The end of this utility model is a frustum-shaped easy-to-insert corner bracket, wherein the middle or right side of the top of the horizontal insert is provided with a recessed groove, and the middle or upper side of the left side of the vertical insert is provided with a left recessed groove.

[0010] The end of this utility model is a frustum-shaped easy-to-insert corner bracket, wherein the horizontal insert, vertical insert, horizontal elastic lever and vertical elastic lever are made of aluminum alloy; the included angle β between the bottom surface of the trapezoidal groove and the horizontal plane is 40°-50°.

[0011] The end of this utility model is a frustum-shaped easy-to-insert corner bracket, wherein the included angle β between the bottom surface of the trapezoidal groove and the horizontal plane is 45°.

[0012] The width of the horizontal elastic lever along the front-back direction is equal to or less than the width of the horizontal insert along the front-back direction, and the width of the vertical elastic lever along the front-back direction is equal to or less than the width of the vertical insert along the front-back direction.

[0013] The end of this utility model is a frustum-shaped easy-to-insert corner bracket, wherein the left side of the upper end of the vertical elastic lever is located at the left end of the left side of the horizontal insert, and the upper surface of the left end of the horizontal elastic lever is located above the upper end of the vertical insert.

The right end of its horizontal insert has a right frustum with a rightward-pointing cone, and the bottom end of its vertical insert has a lower frustum with a downward-pointing cone. Since the end dimensions of the right and lower frustums are much smaller than the inner cavity dimensions of the profile, for automatic door and window frame assembly machines, even with a small gap, the mechanical clamps can easily align and insert the right end of the horizontal insert and the bottom end of the vertical insert into the port of the frame profile when inserting the corner bracket into the frame profile. This solves the problem of quickly and conveniently inserting the corner bracket into the port of the frame profile during automated door and window frame assembly. The technical challenge lies in the fact that the trapezoidal groove has a vertical elastic lever on its left side. The upper end of the vertical elastic lever is a free end that can spring open to the left. Because the free ends of the horizontal and vertical elastic levers respectively abut against the inner wall of the slot in the profile frame, the horizontal and vertical inserts fit together more tightly as they are inserted into the port of the frame profile. This characteristic is very suitable for the needs of automatic door and window frame assembly machines, enabling them to efficiently and quickly complete the automatic assembly of aluminum alloy door and window frames, resulting in very strong and rigid connection at the frame corners. Therefore, the frame corner connecting bracket of this utility model has the characteristics of enabling the automatic assembly of aluminum alloy door and window frames to be completed efficiently and quickly using an automatic door and window frame assembly machine, resulting in very strong and rigid connection at the frame corners.
