Technical Field

[0001] The utility model relates to the field of door and window fittings, in particular to a light and dark hinge reinforcing plate. Background Art

[0002] A visible hinge refers to a hinge form in structures such as doors or windows where the hinge part is clearly exposed and not hidden inside the structure, while a concealed hinge refers to a design where the hinge is hidden inside the structure of the door or window frame and is not easily directly visible from the outside. The reinforcing plates for visible hinges and concealed hinges refer to a special reinforcing plate or mounting seat used when installing these hinges. They are usually used to reinforce the door frame or door leaf to support the installation of the hinge and enhance its stability and load-bearing capacity.

[0003] However, in the prior art, the reinforcing plates for visible hinges and concealed hinges cannot be used compatibly. As a result, not only are two different molds and production lines required, leading to high costs and low efficiency, but also additional inventory space and management costs are needed. Therefore, a light and dark hinge reinforcing plate is proposed to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a light and dark hinge reinforcing plate, aiming to improve the problem of low production efficiency caused by the incompatibility of the reinforcing plates for visible hinges and concealed hinges in the prior art.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: a bright and dark hinge reinforcement plate, including a reinforcement plate 1, the material of the reinforcement plate 1 is high-strength steel, and the high-strength steel has a high yield point and tensile strength and can bear higher loads. Positioning holes 2 are opened on both the upper and lower sides inside the reinforcement plate 1, which are used to ensure that the reinforcement plate 1 can be accurately installed and closely aligned with the door and window structure, thereby improving the installation efficiency and reducing errors. At the same time, the existence of the positioning holes 2 also helps to make fine adjustments during the installation process to ensure the best matching of the hinge reinforcement plate with the door and window frame. Fixing holes 3 are opened on both the upper and lower sides inside the reinforcement plate 1, which are used to firmly fix the reinforcement plate 1 on the door and window structure. Through screws or other fasteners, it can be ensured that the reinforcement plate 1 and the door and window frame form a stable whole, thereby effectively dispersing and bearing the weight and reducing damage caused by improper use or external force. A shaft hole 4 is opened in the middle of the reinforcement plate 1, which is used to accommodate the hinge shaft, enabling the hinge to rotate smoothly. At the same time, the position and size of the shaft hole 4 are precise, ensuring the stability of the hinge and the smooth opening and closing of the door and window. A plurality of hinge mounting holes 5 are opened inside the reinforcement plate 1, and the hinge mounting holes 5 are compatible with the designs of bright hinges and dark hinges, enabling both bright hinges and dark hinges to be installed. Through unified design, trial and error during the installation operation is reduced. A load-bearing component is slidably connected inside the reinforcement plate 1, and the load-bearing component is used to reduce the excessive stress at the hinge part and cause sagging. An antirust coating 8 is provided on the outside of the reinforcement plate 1, and the material of the antirust coating 8 is a chromium plating layer. Chromium plating can provide additional anti-corrosion protection and also improve the appearance quality of the component. The right end of the mounting plate 9 is in contact with the left end of the reinforcement plate 1.

[0029] Refer to Figure 4 , the load-bearing component includes a mounting plate 9, and a plurality of square grooves 10 are opened at the right end of the mounting plate 9, and circular grooves 11 are opened on both the upper and lower sides at the right end of the mounting plate 9.

[0030] Refer to Figure 2 ,Figure 3 , Figure 5 , a positioning rod 6 is slidably connected to the inner wall of the circular groove 11. The positioning rod 6 is made of carbon fiber reinforced plastic, which has the characteristics of light weight and high strength, ensuring the accuracy and stability of positioning. The outer part of the positioning rod 6 is slidably connected to the inner wall of the fixing hole 3.

[0031] Refer to Figure 2 , Figure 3 and Figure 6 , a load-bearing block 7 is slidably connected to the inner wall of the square groove 10. The load-bearing block 7 is made of aluminum alloy. This material selection enables the load-bearing block 7 to have good load-bearing capacity and corrosion resistance. At the same time, the weight of the aluminum alloy is relatively light, which helps to reduce the weight of the overall structure. The right ends of multiple load-bearing blocks 7 are fixedly connected to the left end of the reinforcing plate 1. Such a layout enables the load-bearing blocks 7 to evenly disperse the force, improving the overall load-bearing capacity and stability.

[0032] Working principle: Through the positioning function of the positioning hole 2, the rapid placement of the reinforcing plate 1 is realized. By providing multiple hinge mounting holes 5 on the reinforcing plate 1, the mounting holes of the visible hinge reinforcing plate and the concealed hinge reinforcing plate are designed in a unified form, enabling it to install both visible hinges and concealed hinges, realizing the combination of the visible hinge reinforcing plate and the concealed hinge reinforcing plate into a visible and concealed hinge reinforcing plate, completing the unity in design, reducing the differences between different processes. Since the functions of the two types of reinforcing plates are combined, the time for switching and adjusting processes can be reduced during the production process, greatly improving production efficiency. After the combined design, the inventory of different plate components can be reduced, and at the same time, costs can be reduced in the procurement and production links. Through the integrated design, trial and error during the installation process is reduced, and the error rate is lowered; through the connection between the load-bearing block 7 and the square groove 10, the force received by the reinforcing plate 1 is dispersed into the square groove 10, effectively dispersing the weight. Through the connection between the positioning rod 6 and the circular groove 11, the load-bearing capacity of the reinforcing plate 1 is further improved, thereby reducing the risk of sagging caused by excessive force on the hinge part, and thus extending the service life of the doors and windows.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
