[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention proposes a fire-proof and electric-over-current hinge, comprising a fixed hinge 100 and a movable hinge 200. The fixed hinge 100 is provided with a first connecting cylinder 110, and the movable hinge 200 is provided with a second connecting cylinder. The first connecting cylinder 110 and the second connecting cylinder are connected by a rotating shaft 300, and the rotating shaft 300 is provided with a wire-passing channel 310 passing through the rotating shaft 300. The fixed hinge 100 is provided with a first wire-passing groove 120, and the movable hinge 200 is provided with a second wire-passing groove 220.

[0024] In a specific embodiment, the fixed hinge 100 is used to connect one end of the door frame, and the fixed hinge 100 is provided with a first connecting cylinder 110. The first connecting cylinder 110 has a first installation channel 110 formed therein for installing and supporting a part of the rotating shaft 300. The movable hinge 200 is used to connect the other end of the door panel, and the movable hinge 200 is provided with a second connecting cylinder. The second connecting cylinder has a second installation channel 210 formed therein, which corresponds to the first installation channel 110 and is used together to install and support the same rotating shaft 300.

[0025] The rotating shaft 300 is a key component for connecting the fixed hinge 100 and the movable hinge 200. It not only realizes the rotation connection between the two, but also has a wire-passing channel 310. The wire-passing channel 310, the first installation channel 110 and the second installation channel 210 are coaxially arranged to ensure that the wire 700 can pass smoothly and unimpeded. The wire-passing channel 310 is located on the rotating shaft 300 and is used to pass the power line, so that the power line can remain continuous and unaffected when the door leaf is opened or closed.

[0026] The first wire groove 120 and the second wire groove 220 are respectively arranged on the fixed hinge 100 and the movable hinge 200, and are connected to the wire passage 310. The first wire groove 120 and the second wire groove 220 enable the power line to be smoothly led out or introduced from the inside of the hinge, which is convenient for connection with the external circuit. The wire outlet 500 is respectively provided on the fixed hinge 100 and the movable hinge 200 to communicate with the first wire groove 120 and the second wire groove 220, which is used for the final lead-out of the power line to ensure that the layout of the line is neat and safe.

[0027] It should be noted that in order to enhance the fireproof function, the hinge material of the present invention is made of an alloy material with excellent flame retardant properties. At the same time, the wire passage 310, the first wire trough 120, the second wire trough 220 and the wire outlet 500, etc., through which the wires 700 pass, are treated with fireproof sealing materials to ensure that when a fire occurs, the fire can be effectively prevented from spreading through these passages, protecting the wires 700 from being burned, thereby maintaining the normal operation of the electrical equipment or at least reducing the damage caused by the fire.

[0028] It is understandable that a wire-passing channel 310 is provided inside the rotating shaft 300, and the wire-passing channel 310 is coaxially arranged with the first installation channel 110 and the second installation channel 210, thereby allowing the wire 700 to pass freely between the fixed hinge 100 and the movable hinge 200 through the wire-passing channel 310 without being exposed to the external environment. The wire 700 is completely hidden inside the hinge, avoiding the problem of the wire 700 being exposed in the traditional design, and improving the overall aesthetics of the interior decoration. In order to further achieve the complete hiding of the wire 700, a first wire-passing groove 120 and a second wire-passing groove 220 are respectively provided on the fixed hinge 100 and the movable hinge 200, and these two wire-passing grooves are respectively connected to the wire-passing channel 310. The wires 700 can smoothly transition in these grooves until they are led out through the wire outlets 500 provided on the fixed hinge 100 and the movable hinge 200, and are used to connect the electrical equipment on the door leaf or door frame, so as to achieve complete hiding of the wires 700. The fixed hinge 100 and the movable hinge 200 are respectively provided with a first wire groove 120 and a second wire groove 220, and the two wire grooves are respectively connected to the wire passage 310. The wires 700 can smoothly transition in these grooves until they are led out through the wire outlets 500 provided on the fixed hinge 100 and the movable hinge 200, and are used to connect the electrical equipment on the door leaf or door frame, so as to prevent the exposed wires 700 from becoming a medium for the spread of fire.

[0029] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the fixed hinge 100 is connected to the first connecting cylinder 110 via a first connecting arm 130, and the movable hinge 200 is connected to the second connecting cylinder via a second connecting arm 230. The two connecting arms not only enhance the structural strength of the hinge, but also provide additional space for hiding the wire 700.

[0030] In particular, the first connecting arm 130 and the second connecting arm 230 are arranged at a certain angle to each other, so that when the hinge is installed on the door frame and the door panel, it can better adapt to the angle changes when the door leaf is opened and closed, while ensuring the smooth passage of the wire 700 inside the hinge, and increasing the length of the hidden part of the wire 700 inside the hinge. As the wire 700 rotates inside the hinge, it plays a certain buffering role, reducing the risk of short circuit or even shearing caused by the winding of the wire 700.

[0031] Furthermore, a first connection channel 131 and a second connection channel 231 are respectively provided on the first connection arm 130 and the second connection arm 230. The two channels are respectively connected to the first wire groove 120 and the first installation channel 110, and the second wire groove 220 and the second installation channel 210. In this way, the wire 700 can enter the corresponding installation channel from the outside of the fixed hinge 100 or the movable hinge 200 through the connection arm, and then pass through the wire channel 310 to the other side, so that the wire 700 is completely hidden.

[0032] It should be noted that the diameter of the channel for hiding the wires 700 formed by the fixed hinge 100, the movable hinge 200, the first connecting arm 130, the second connecting wall and the rotating shaft 300 proposed in the present invention is at least sufficient to accommodate 12 wires 700 passing through.

[0033] In order to further optimize the path of the wire 700, a first wire hole 140 is provided on the inner side wall of the first connecting cylinder 110, which is connected to the first connecting channel 131 and the first wire groove 120; similarly, a second wire hole 240 is provided on the inner side wall of the second connecting cylinder, which is connected to the second connecting channel 231 and the second wire groove 220. In this way, the wire 700 can pass through the first wire hole 140 from the first wire groove 120 to the wire channel 310 more smoothly, and then pass through the second wire hole 240 to the second wire groove 220, thereby avoiding the bending and squeezing of the wire 700 inside the hinge.

[0034] Reference Figure 3 and Figure 4 In some embodiments, in order to meet the requirements of different installation heights, a height adjustment nut 400 is connected to the bottom of the rotating shaft 300. In particular, the height adjustment nut 400 is located in the first installation channel 110, and is provided with a clearance channel 410 coaxial with the wire passage 310 to ensure that the wire 700 can pass smoothly, so that the user can adjust the height of the door leaf according to the actual situation to achieve the best installation effect.

[0035] In order to cooperate with the use of the height adjustment nut 400, a through-hole is set at the bottom of the first connecting cylinder 110, and the hole is connected to the first installation channel 110. In this way, when the height needs to be adjusted, the user can easily operate the height adjustment nut 400 without worrying about it interfering with the first connecting cylinder 110. Furthermore, in order to keep the interior of the hinge clean and beautiful, a cover plate 150 is set on the first connecting cylinder 110 to close the hole. This cover plate 150 can not only prevent dust and debris from entering the interior of the hinge, but also protect the wire 700 from interference from the external environment.

[0036] Reference Figure 1In order to facilitate the installation and maintenance of the wire 700, a detachable cover plate 600 is provided on the fixed hinge 100 and the movable hinge 200. These cover plates 600 can be used to open or close the first wire groove 120 and the second wire groove 220, so that the user can easily access or replace the wire 700 when necessary.

[0037] In order to improve the rotation stability and service life of the rotating shaft 300, a tensioning copper sleeve is mounted on the rotating shaft 300. The copper sleeve is located in the second installation channel 210 and fits tightly with the inner wall of the second installation channel 210. The design of the tensioning copper sleeve can not only reduce the friction between the rotating shaft 300 and the installation channel, but also prevent the rotating shaft 300 from loosening or deflecting during the rotation process.

[0038] Through the first connecting arm 130 and the second connecting arm 230, as well as the height adjustment nut 400 and the tensioning copper sleeve, the structure of the fireproof current-passing hinge is more reasonable and stable, and the opening and closing effect of the door leaf is improved. Through the design of the first wire groove 120, the second wire groove 220, the first connecting channel 131, the second connecting channel 231, the first wire hole 140 and the second wire hole 240, the wire 700 is completely hidden, the overall aesthetics of the interior decoration is improved, and the exposed wire 700 is prevented from becoming a fuse for the spread of fire, thereby improving the fireproof performance. The detachable sealing plate 600 and the height adjustment nut 400 make the installation and maintenance of the wire 700 more convenient, and the height of the door leaf can be adjusted according to the actual situation to achieve the best installation effect.

[0039] The second aspect of the present invention also proposes a door leaf assembly, which includes the above-mentioned fireproof over-current hinge, door frame and door panel. The door panel is rotatably connected to the door frame through the fireproof over-current hinge, thereby realizing the opening and closing functions of the door leaf. Due to the use of the fireproof over-current hinge, the door leaf assembly not only has all the functions of the traditional door leaf assembly, but also provides the additional functions of hiding and fire protection of the wires 700, making the entire door leaf assembly more beautiful, safe and practical. It should be noted that the fireproof over-current hinge is not only suitable for ordinary door leaf assemblies, but can also be widely used in special occasions where the wires 700 need to be hidden and fire-protected, such as fire escape doors, machine room doors, etc., and has strong practicality.

[0040] In some embodiments, an intelligent sensing function is added to the basic fireproof and over-current hinge. Specifically, an infrared sensor or a magnetic induction sensor is integrated on the fixed hinge 100 or the movable hinge 200 to detect the opening and closing status of the door leaf. When the door leaf is opened or closed, the sensor triggers a corresponding signal, and sends the signal to the central control system or the user's smartphone through the built-in wireless communication module. In this way, the user can not only monitor the status of the door leaf in real time, but also remotely control the opening and closing of the door leaf, which improves safety and convenience.

[0041] In addition, in order to further improve the practicality and aesthetics of the door leaf assembly, the present embodiment provides a fire-proof and over-current-proof hinge with a lighting function. Specifically, an LED light strip or a small lighting fixture is integrated on the fixed hinge 100 or the movable hinge 200 to provide a lighting effect when the door leaf is opened or closed. These lighting fixtures can be powered by a built-in power supply or battery and can be controlled by a remote control or a touch switch.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
