Description

Technical Field

[0001] The utility model relates to the field of building doors and windows, in particular to an angle bracket for windows. Background Art

[0002] At present, the corner connection of door and window frames generally requires aluminum corners. The corner connection of the corner and the profile is hit by the props on the corner assembly equipment to deform the profile at the impact to the concave part of the corner. Another way to connect the corners is to connect the two ends of the profile with the corner in the corresponding cavity with screws or pins to achieve the purpose of corner connection. The convenience of screw or pin corner assembly is that it does not require professional equipment and can be completed at the installation site. For doors and windows with larger specifications and sizes, the finished doors and windows are not conducive to transportation and carrying upstairs. Therefore, corner assembly at the installation site will improve efficiency and save labor. Because the thermal insulation profile is divided into two cavities, one cavity is large and usually uses screws for corner connection, and the other cavity is small and generally uses pins for corner connection. Therefore, the same profile may be connected with two types of nails. In order to facilitate the screw assembly during the production process, the angle code is usually divided into an upper and lower body, with the thread occupying half of each of the upper and lower bodies, which together form a complete thread. This is to facilitate mold processing and forming. For small profile cavities, it is not suitable to split the angle code. Generally, a semicircular opening is made on it and pins are used to connect it. The connection strength of the pin is lower than that of the screw, and it is not conducive to standardized production. If the angle code is separately drilled and tapped for secondary processing and the thread is specially manufactured, the labor cost will be greatly increased and the competitiveness of the profile will be impaired.

[0003] After searching, the publication number: CN209761232U discloses a corner code for fastening doors and windows, which includes a first connecting arm, a second connecting arm, an assembly groove, a threaded hole, a fastener, a screw, a nut, a positioning piece, and a sealing cover. The angle between the first connecting arm and the second connecting arm is 90 degrees. The end faces of the first connecting arm and the second connecting arm are inclined, and the first connecting arm and the second connecting arm are respectively provided with an assembly groove near the end face. The inclination of the assembly groove is consistent with the inclination of the end face wall. A threaded hole is provided above the center of the assembly groove, and a fastener is installed in the assembly groove. After adopting the above technical scheme, the beneficial effects of the utility model are as follows: it is not only novel in design and strengthens the fastening effect of the corner code, but also has a low production cost and is suitable for wide promotion and use. Although the application achieves the effect of strengthening the fastening effect of the corner code through the cooperation of the fastener and the assembly groove, it does not mention how to design the thread inside the small cavity angle code, and there is a problem that it is not convenient to process and manufacture the thread in mold manufacturing. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a window angle code, aiming to improve the problem that the prior art does not mention how to design the threads inside the small cavity angle code, and there is a problem that it is inconvenient to process and manufacture the threads during mold manufacturing.

[0006] Furthermore, a cavity 1 is provided inside the first connecting rod and inside the second connecting rod.

[0007] Furthermore, a second cavity is provided inside the first connecting rod and inside the second connecting rod.

[0008] Furthermore, the first connecting rod and the second connecting rod are both made of aluminum alloy.

[0009] Furthermore, the impact corner area is of concave design and has a trapezoidal shape.

[0010] Furthermore, the glue injection area is of concave design and has a triangular shape.

[0011] Furthermore, the included angle between the first connecting rod and the second connecting rod is ninety degrees.

[0012] Furthermore, the glue injection area is arranged at a position where the outer wall of the first connecting rod and the outer wall of the second connecting rod are separated from each other by an angle of ninety degrees.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, screws can be normally used for corner assembly through special design, thereby achieving the effect of increasing the connection strength of the corners of doors and windows, and the effect of enhancing the strength of the profile corner assembly is achieved through the cooperation of the corner collision area and the glue injection area.

[0015] 2. In the utility model, since the thermal insulation profile is divided into two cavities, one cavity is large and is usually connected by screws, and the other cavity is small and is generally connected by pins.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-2 The utility model provides an embodiment: a window corner code, including a first connecting rod 1, the outer wall of the first connecting rod 1 is fixedly connected to the second connecting rod 2, the outer wall of the second connecting rod 2 is provided with a glue injection area 4, the interior of the second connecting rod 2 is provided with a first opening groove 6, the interior of the second connecting rod 2 is provided with a second opening groove 7, the first opening groove 6 and the second opening groove 7 are through-designed, the outer wall of the second connecting rod 2 is provided with a glue injection area 4, and the outer wall of the second connecting rod 2 is provided with a corner collision area 5.

[0022] Specifically, the uniqueness of this angle code lies in the threaded hole that passes through the first opening groove 6 and the second opening groove 7. When using screws to assemble the angle, the two sets of threads can be said to be more firmly connected to the screws and the angle code. A collision area 5 is provided. This design makes the angle code easier and faster to assemble. The collision area 5 refers to an impact surface set at a specific position of the angle code, and the collision assembly is performed by equipment. This design not only improves production efficiency, but also reduces labor costs. The traditional angle code assembly process often requires manual operation and is prone to errors. The collision design of this angle code allows the assembly process to be completely completed by equipment, greatly improving the assembly accuracy.

[0023] Reference Figure 1 and Figure 2 A cavity 3 is provided inside the first connecting rod 1 and the second connecting rod 2; a cavity 2 8 is provided inside the first connecting rod 1 and the second connecting rod 2, and the first connecting rod 1 and the second connecting rod 2 are both made of aluminum alloy; the collision area 5 is a recessed design with a trapezoidal shape; the glue injection area 4 is a recessed design with a triangular shape; the angle between the first connecting rod 1 and the second connecting rod 2 is ninety degrees; the glue injection area 4 is arranged at a position where the outer wall of the first connecting rod 1 and the outer wall of the second connecting rod 2 deviate from the angle of ninety degrees.

[0024] Specifically, the design of the glue injection area 4 allows the glue to be evenly applied to the connection between the corner bracket and the profile, thereby improving the fastening effect. Compared with traditional fastening methods, the fastening effect of the glue injection area 4 is more obvious, and can significantly improve the connection strength between the corner bracket and the profile. The glue used has excellent weather resistance and anti-aging properties, making the connection more durable. Glue injection in the glue injection area 4 can ensure that the connection between the corner bracket and the profile is firm and reliable, thereby improving the safety of buildings and products.

[0025] Working principle: When a window angle code is needed, the first connecting rod 1 and the second connecting rod 2 are first die-cast into an integrated structure, and a cavity 1 3 and a cavity 2 8 are opened inside the first connecting rod 1 and the second connecting rod 2. An angle assembly device is used for angle connection, and screws can also be used for angle connection. A first opening groove 6 is designed vertically upward in the screw position area, and a thread is designed in the first opening groove 6. A second opening groove 7 is also provided in the vertically downward direction, and a thread is also designed in the second groove. The threads in the two grooves are through-designed. During the assembly of the profile, the screw is screwed in through the screw hole outside the cavity. Under the constraint of the profile hole, the screw passes through the thread of the first opening groove 6 and enters the thread of the second opening groove 7. In this way, the entire screw fastens the profile and the angle code under the constraints of the profile opening and the first and second opening threads. At the same time, the angle code is also provided with an angle collision area 5, which can be assembled by the equipment. After the assembly is completed, the glue injection area 4 can be used for glue injection to achieve enhanced fastening of the angle code and the profile.
