Description

Technical Field

[0001] The utility model relates to the technical field of hollow glass windows, in particular to a corner connecting device for an outer frame of a hollow glass window with greater stability. Background Art

[0002] Hollow built-in roller shutter glass windows consist of a window frame, glass cover panels covering both sides of the window frame, and a roller shutter device placed between the two glass cover panels. The outer frame of the window frame is connected to the four partition edges by corner connectors to form a whole.

[0003] While traditional corner connectors can, under ideal conditions, precisely mate with the spacer strips during precise mold opening, window system manufacturers in the real world often need to source components from multiple suppliers. Different suppliers' production processes and material properties (such as plastic deformation during cooling) can lead to deviations between the final product and the designed dimensions, reducing overall product yield and increasing the difficulty of matching components.

[0004] Furthermore, existing frame corner connector designs typically only feature beveled teeth above or below the pins, a design that can only accommodate errors in the height of the sockets. However, in actual applications, errors in the width of the frame profile sockets also frequently occur. When using existing corner connectors, workers often need to use a utility knife to cut both sides of the connector to achieve a match. This process not only reduces assembly efficiency, but also often leads to over-cutting due to the difficulty in controlling cutting errors. As a result, excess space may remain on both sides after the pins are inserted, causing the frame to have a swing margin in the left-right direction, which in turn affects the overall stability of the window. Therefore, there is a need for a corner connector that can accommodate both height and width errors to improve the assembly efficiency and stability of the window system. Utility Model Content

[0005] The technical purpose of the utility model is to provide a more stable corner connection device for the outer frame of a hollow glass window, which can simultaneously adapt to corner connectors with height and width errors to improve the assembly efficiency and stability of the window system.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A more stable corner connection device for the outer frame of a hollow glass window includes two mutually perpendicular connected pins; the characteristics are that the top surface of the pin is provided with convex teeth, the two side surfaces of the pin are provided with oblique teeth, and the bottom surface of the pin is provided with a boss.

[0008] According to a further preferred technical solution, the toes of the pins are inclined.

[0009] According to a further preferred technical solution, the oblique edge teeth face obliquely rearward and form an acute angle with the straight side of the pin.

[0010] According to a further preferred technical solution, the convex teeth are correspondingly arranged between two adjacent oblique teeth.

[0011] A further preferred technical solution is that one of the pins has a pin extension on its body. This pin extension is hollow and has multiple lattice-like compartments inside. The hollow structure helps reduce material weight, provides a certain degree of flexibility to accommodate errors between frames, and provides better stability during insertion.

[0012] The beneficial effect of the present invention is that the design of the device takes into account both the compensation of height errors and the adaptability of width errors. The tooth-like structures of the pin portion and the corner portion have good gripping functions, helping to provide stability in different directions and prevent loosening or shaking of the frame connection.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, a more stable corner connection device for the outer frame of a hollow glass window includes two pins connected perpendicularly to each other, namely a first pin 1 and a second pin 2. The specific structure and working principle of the device are as follows:

[0019] Pin structure:

[0020] 1. Top Surface Design: The top surface of the pin is equipped with multiple evenly distributed ridges 3. These ridges 3 are perpendicular to the top surface of the pin. This ridge structure effectively increases the friction between the pin and the inner wall of the frame during insertion, preventing loosening and enhancing the stability of the device.

[0021] 2. Side Design: Beveled teeth 4 are located on both sides of the pin. Each beveled tooth 4 is angled toward the rear of the pin and forms an acute angle with the straight edge of the pin. The angled design of the beveled teeth 4 provides a strong secure fit during insertion, preventing the pin from coming loose. The distribution and angle of the beveled teeth further optimize the connector's embedded stability within the frame.

[0022] 3. Bottom Design: A boss 5 is located on the bottom of the pin. This boss, in conjunction with the rest of the pin structure, provides additional support, making the device more stable after installation. The boss also prevents the pin from being over-inserted into the frame, ensuring installation accuracy.

[0023] 4. Pin Tip Design: The pin tips are beveled, facilitating smooth insertion into the frame and reducing initial resistance. This beveled tip also improves installation efficiency and avoids insertion difficulties caused by alignment issues.

[0024] The synergistic effect of bevel teeth and convex teeth:

[0025] The ridges 3 are located on the top surface of the pin, adjacent to the beveled ridges 4 on either side. Each ridge is positioned between two adjacent beveled ridges, ensuring full contact between the pin and the frame, further enhancing the device's securement within the frame. The combined design of the ridges 3 and 4 ensures excellent embedding and retention within the frame, ensuring it resists loosening even during extended use.

[0026] Pin extension design, such as Figure 3 As shown:

[0027] One of the pins is provided with a pin extension 6 on its main body. The pin extension 6 is hollow and has multiple grid-like compartments inside. The advantages of the hollow structure design are:

[0028] 1. Weight reduction: By reducing the amount of materials used, the weight of the entire device is reduced, making installation easier.

[0029] 2. Elastic adaptability: The hollow lattice-shaped partition has a certain degree of elasticity, which can adapt to the errors between the frames and avoid the device from not fitting tightly due to incomplete size matching.

[0030] 3. Enhanced stability: The lattice-shaped partition not only provides flexibility, but also acts as a stabilizer when the pin is inserted into the frame, ensuring the tightness of the pin in the frame.

[0031] advantage:

[0032] This new design utilizes ridges and beveled teeth on the top and sides of the pins, as well as a boss on the bottom and a beveled structure on the toe, to achieve a smooth connection between the pins and the frame, enhancing the stability of the connection. The hollow pin extension not only reduces the weight of the device but also provides good flexibility, accommodating errors between the frames, ensuring convenient installation and long-term stability.
