Description

Technical Field

[0001] This application belongs to the technical field of doors, and particularly relates to a cast aluminum door with a hinge hidden structure. Background Art

[0002] Anti-theft doors are indispensable safety facilities in people's daily lives, and their design needs to take into account both anti-theft and safety performance. Usually, the hinges used on anti-theft doors are double-leaf knuckle hinges, which can achieve flexible connection between the door panel and the door frame. However, such hinges also have some problems.

[0003] Firstly, such hinges usually need to be fixed on the sides of the door panel and the door frame, and the welding points for fixing the hinges are usually exposed. In this way, whether the door panel is open or closed, people can directly see the exposed hinges, which undoubtedly affects the aesthetics of the anti-theft door.

[0004] The patent with the publication number CN104763294B discloses a 90-mm-thick integral full-lock tongue anti-theft door, including a square door frame and a door body composed of a threshold, a lintel, a lock hole frame, and a hinge frame; the lock hole frame is bent inward to form a concave tongue groove; the door body is provided with a full-lock tongue corresponding to the concave tongue groove of the lock hole frame. The lock hole frame is integrally formed by folding a front stop line, a rear stop line, a decorative surface, an extended connecting block, and a door edge line; the front stop line is fixedly connected to the door edge line through the extended connecting block; the extended connecting block is designed according to the thickness of the wall; it is very beautiful and practical.

[0005] The hinge fixed on one side of the anti-theft door panel and the door frame in the above patent is exposed and not beautiful, and needs to be improved. Utility Model Content

[0006] The purpose of this application is to provide a cast aluminum door with a hinge hidden structure, which can solve the above problems.

[0007] The purpose of this application is to provide a cast aluminum door with a hinge hidden structure, including:

[0008] A door frame, including a first frame body and a second frame body;

[0009] A door leaf;

[0010] A hidden through-axis hinge profile, arranged on the first frame body;

[0011] A hidden through-axis hinge, one end of which is connected to the first frame body, and the other end is connected to the hidden through-axis hinge profile;

[0012] Wherein, it further includes a hidden storage groove, arranged on the door leaf and used for installing and storing the hidden through-axis hinge profile.

[0013] Adopting the above-mentioned cast aluminum door with a hinge hidden structure, by hiding the hidden through-axis hinge and its profile in the hidden storage groove inside the door leaf, it completely solves the problem that the hinges of traditional anti-theft doors are exposed and affect the overall aesthetics. When the cast aluminum door is in the closed state, its surface is flat without protrusions, perfectly integrated with the door frame, enhancing the overall decorative effect of the home or commercial place. Although the main purpose is to improve aesthetics, the hidden design also indirectly enhances the security of the door, protecting key connection components such as hinges, reducing the possibility of being maliciously damaged or pried, and thus increasing the anti-prying ability of the anti-theft door.

[0014] At the same time, when the user opens and closes the door, due to the smooth operation and hidden design of the hinge, the opening and closing actions of the door will be more stable and silent, improving the comfort and experience of use. Moreover, the hidden design also reduces the collision risk that may be caused by the protruding hinge, ensuring the use safety. In addition, the present utility model is not only applicable to cast aluminum doors, but its design concept and technical solutions can also be flexibly applied to anti-theft doors and interior doors made of other materials, with strong versatility and popularization value.

[0015] Furthermore, an outer sticker layer is provided on the outer side of the door leaf. The two ends of the outer sticker layer are respectively provided with a first shielding part and a second shielding part. The first shielding part is connected to the hidden through-axis hinge profile and shields the hidden through-axis hinge.

[0016] The first shielding part is directly connected to the hidden through-axis hinge profile and effectively shields the exposed part of the hinge. This direct connection method ensures the tightness and stability of the shielding, avoiding the problem of shielding failure caused by long-term use or external forces. The second shielding part is used to shield the components on the other side of the door leaf. The design of the outer sticker layer and the shielding parts at its two ends makes the appearance of the door leaf smoother and neater. Whether observed from the front or the side, the hinges cannot be seen, thus enhancing the overall aesthetics of the door body.

[0017] At the same time, the outer sticker layer, the first shielding part, and the second shielding part are made of wear-resistant and corrosion-resistant materials, which can effectively protect the door leaf body from the erosion of the external environment, protect the hidden through-axis hinge profile and the hidden through-axis hinge, and also avoid the risk of accidental collision or scratching caused by the protruding hinge, improving the safety and comfort of use.

[0018] Furthermore: The hidden through-axis hinge profile includes a mounting plate and a connecting plate connected to each other. The mounting plate is arranged in the hidden storage groove, and a connecting shaft is provided on the connecting member;

[0019] The hidden through-axis hinge includes a fixing part and a connecting part connected to each other. The fixing part is connected to the first frame body, and the connecting part is connected to the connecting shaft;

[0020] Among them, the connecting member is installed on the first shielding part.

[0021] The concealed coaxial hinge profile is formed by connecting an installation plate and a connecting plate. The installation plate is designed to be installed in the concealed storage groove of the door leaf, which not only hides a part of the hinge but also ensures the stable installation of the hinge profile. The connecting plate is responsible for connecting the other parts of the concealed coaxial hinge and acts as a bridge. A connecting shaft is provided on the connecting plate, which cooperates with the connecting part of the concealed coaxial hinge to achieve smooth rotation between the door leaf and the door frame. The concealed coaxial hinge is formed by connecting a fixed part and a connecting part. The fixed part is firmly connected to the first frame body to ensure the overall stability of the hinge, and the connecting part is connected to the connecting shaft of the concealed coaxial hinge profile. The opening and closing of the door leaf are realized through the rotation of the connecting shaft. The connecting piece is installed on the first shielding part, which not only plays a role in fixing the concealed coaxial hinge but also uses the first shielding part to further hide the visible part of the hinge, enhancing not only the stability of the hinge but also the overall aesthetics of the door leaf.

[0022] Furthermore, a first card slot is provided on the installation plate, and a first buffer member is arranged in the first card slot. A protrusion adapted to the first card slot is provided on the first buffer member, and one end of the first buffer member away from the concealed coaxial hinge profile can contact the first frame body when the door leaf is closed.

[0023] The adaptation design of the protrusion on the first buffer member and the first card slot enhances the connection stability between the buffer member and the installation plate, preventing the buffer member from shifting or falling off during use, thus ensuring the smoothness of the door leaf during opening and closing. The main function of the first buffer member is to provide buffering when the door leaf is closed, reducing the direct collision between the door leaf and the door frame, not only reducing noise but also extending the service life of the door leaf and the door frame, avoiding damage caused by long-term collision.

[0024] At the same time, when the door leaf is closed, one end of the first buffer member away from the concealed coaxial hinge profile can contact the first frame body, thereby achieving the buffering effect and ensuring that the door leaf can fit smoothly against the door frame slowly and steadily when closed, improving the comfort and safety of use. It makes the closing action of the door leaf softer, reducing the impact force generated by sudden closing, not only enhancing the user experience but also making the door leaf quieter when closed, reducing the impact of noise on the surrounding environment.

[0025] In addition, due to the presence of the buffer member, the door leaf can maintain a stable closed state even when slightly disturbed by external forces during closing, avoiding problems such as the door leaf rebounding or not closing completely due to external forces.

[0026] Furthermore, an installation profile is provided on the side of the door leaf away from the hinged end, and a positioning slot is provided on the installation profile groove, and a lock is arranged in the positioning slot.

[0027] By setting a positioning groove on the installation profile, the lock can be more firmly fixed on the door leaf, avoiding the problems of looseness or damage that may occur when the lock is directly installed on the surface of the door leaf, improving the service life and safety of the lock. And the setting of the positioning groove enables the lock to be accurately positioned at the predetermined position during installation, not only simplifying the installation process, but also ensuring that the lock hole on the lock is accurately aligned with the lock hole on the door frame, thus improving the use effect and safety of the lock.

[0028] Furthermore, a second card slot is also provided on the installation profile, and a second buffer member is arranged in the second card slot. The structure of the second buffer member is the same as that of the first buffer member, and the second buffer member contacts the second frame when the door leaf is closed.

[0029] The setting of the second buffer member enables the door leaf to have not only the first buffer member to provide buffering at the hinge end when the door leaf is closed, but also the second buffer member to buffer on the side far from the hinge end. This double buffer design significantly reduces the impact force when the door leaf is closed, reduces noise, and extends the service life of the door leaf and the door frame.

[0030] At the same time, the contact between the second buffer member and the second frame ensures that the door leaf can fit smoothly on the door frame when it is closed, helping to prevent the door leaf from shaking or generating noise due to external factors such as wind and vibration, and improving the stability of the door leaf. And the structure of the second buffer member is the same as that of the first buffer member, and they are consistent in material, size and performance, simplifying the production and installation process, reducing costs, and ensuring the balance of the buffer effect of the entire door body.

[0031] In addition, the double buffer design makes the closing action of the door leaf softer and smoother, improving the user experience. When the user closes the door leaf, there is no need to worry about noise or vibration problems caused by excessive impact force, helping to prevent the door leaf from being damaged or deformed due to excessive impact, thus maintaining the integrity and protection performance of the door body, and increasing the comfort and satisfaction of use.

[0032] The beneficial effects of this application are:

[0033] 1. By hiding the hidden through-axis hinge and its profile in the hidden storage groove in the door leaf, the problem that the hinges of traditional anti-theft doors are exposed and affect the overall aesthetics is completely solved. When the cast aluminum door is in the closed state, the surface is flat without protrusions and perfectly integrates with the door frame, improving the overall decoration effect of the home or commercial place;

[0034] 2. The hidden design also enhances the security of the door, protecting key connecting components such as hinges, reducing the possibility of malicious damage or prying, and thus increasing the anti-prying ability of the anti-theft door. At the same time, when the user opens and closes the door, due to the smooth operation and hidden design of the hinge, the opening and closing actions of the door will be more stable and silent, improving the comfort and experience of use. Moreover, the hidden design also reduces the collision risk that may be caused by the protruding hinge, ensuring the use safety;

[0035] 3. Through the setting of the first buffer member and the second buffer member, the double buffering makes the closing action of the door leaf softer and smoother, improving the user experience. When the user closes the door leaf, there is no need to worry about noise or vibration problems caused by excessive impact force, which helps prevent the door leaf from being damaged or deformed due to excessive impact, thus maintaining the integrity and protection performance of the door body, and increasing the comfort and satisfaction of use.
