[0025] Referring to Figure 1 , Figure 2 , Figure 3 And Figure 4The utility model provides a kind of fireproof overcurrent hinge, including first fixed plate 100, second fixed plate 200, first fixed plate 100 is provided with first connecting barrel 110, second fixed plate 200 is provided with second connecting barrel, first connecting barrel 110, second connecting barrel are connected by shaft 300 between, and shaft 300 is provided with and penetrates the wire passage 310, first fixed plate 100 is provided with first wire slot 120, second fixed plate 200 is provided with second wire slot 220.
[0026] In specific embodiments, the first fixed plate 100 is used to connect one end of the door frame, and the first fixed plate 100 is provided with a first connecting barrel 110. Inside the first connecting barrel 110, a first mounting channel 110 is formed for mounting and supporting a portion of the shaft 300. The second fixed plate 200 is used to connect the other end of the door panel, and the second fixed plate 200 is provided with a second connecting barrel. Inside the second connecting barrel, a second mounting channel 210 is formed, corresponding to the first mounting channel 110, for mounting and supporting the same shaft 300.
[0027] The shaft 300, as a key component connecting the first fixed plate 100 and the second fixed plate 200, not only realizes the rotational connection of the two, but also is specially provided with a wire passage 310 that penetrates through. The wire passage 310, the first mounting channel 110, and the second mounting channel 210 are coaxially arranged to ensure that the electric wire 700 can pass smoothly and unobstructed. Moreover, the wire passage 310 is located on the shaft 300, used for threading the power line, so that the power line can remain continuous and unaffected in the open or closed state of the door leaf.
[0028] The first wire slot 120 and the second wire slot 220 are respectively arranged on the first fixed plate 100 and the second fixed plate 200, and are in communication with the wire passage 310. The first wire slot 120 and the second wire slot 220 enable the power line to be smoothly led out or introduced from the hinge interior, facilitating connection with the external circuit. The outlet 500 is provided with an outlet 500 in communication with the first wire slot 120 and the second wire slot 220 on the first fixed plate 100 and the second fixed plate 200, respectively, for the final leading out of the power line, ensuring that the layout of the line is neat and safe.
[0029] It should be noted that, in order to improve the fireproof function, the hinge material of the utility model is selected to be an alloy material with excellent flame-retardant performance. At the same time, the parts through which the electric wire 700 passes, such as the wire passage 310, the first wire slot 120, the second wire slot 220, and the outlet 500, are treated with fireproof sealing materials, ensuring that the fire can be effectively prevented from spreading through these channels when a fire occurs, protecting the electric wire 700 from being burned out, thereby maintaining the normal operation of electrical equipment or at least reducing the damage caused by the fire.
[0030] It can be understood that the rotating shaft 300 is internally provided with a through line channel 310 coaxially arranged with the first mounting channel 110 and the second mounting channel 210, so as to allow the electric wire 700 to freely pass through the through line channel 310 between the first fixed plate 100 and the second fixed plate 200 without being exposed to the external environment. The electric wire 700 is completely hidden inside the hinge, avoiding the problem of exposed electric wire 700 in the traditional design, and improving the overall aesthetics of the indoor decoration. In order to further realize the complete hiding of the electric wire 700, the first fixed plate 100 and the second fixed plate 200 are respectively provided with a first wire slot 120 and a second wire slot 220, which are respectively connected with the through line channel 310. The electric wire 700 can smoothly transition in these slots until it is led out through the wire outlet 500 provided on the first fixed plate 100 and the second fixed plate 200 for connecting electrical equipment on the door leaf or the door frame, realizing the complete hiding of the electric wire 700, the first fixed plate 100 and the second fixed plate 200 are respectively provided with a first wire slot 120 and a second wire slot 220, which are respectively connected with the through line channel 310. The electric wire 700 can smoothly transition in these slots until it is led out through the wire outlet 500 provided on the first fixed plate 100 and the second fixed plate 200 for connecting electrical equipment on the door leaf or the door frame, preventing the exposed electric wire 700 from becoming a medium for fire spread.
[0031] Referring to Figure 1 , Figure 2 and Figure 3 , specifically, the first fixed plate 100 is connected with the first connecting cylinder 110 through the first connecting arm 130, and the second fixed plate 200 is connected with the second connecting cylinder through the second connecting arm 230. These two connecting arms not only enhance the structural strength of the hinge, but also provide additional space for the hiding of the electric wire 700.
[0032] In particular, the first connecting arm 130 and the second connecting arm 230 are arranged at a certain angle with each other, so that the hinge can better adapt to the angle change of the door leaf when opening and closing when installed on the door frame and the door plate, while ensuring the smooth passage of the electric wire 700 inside the hinge, and increasing the length of the hidden part of the electric wire 700 inside the hinge. When the electric wire 700 follows the rotation inside the hinge, it plays a certain buffering role, reducing the risk of short circuit or even shearing caused by winding of the electric wire 700.
[0033] Further, on the first connecting arm 130 and the second connecting arm 230, a first connecting channel 131 and a second connecting channel 231 are respectively arranged. The two channels respectively communicate the first wire passing groove 120 and the first mounting channel 110, and the second wire passing groove 220 and the second mounting channel 210. In this way, the electric wire 700 can pass through the connecting arm from the outside of the first fixed plate 100 or the second fixed plate 200 into the corresponding mounting channel, and then pass through the wire passing channel 310 to the other side, realizing the complete hiding of the electric wire 700.
[0034] It should be noted that the channel diameter formed by the first fixed plate 100, the second fixed plate 200, the first connecting arm 130, the second connecting wall and the shaft 300 of the utility model for hiding the electric wire 700 is at least enough to accommodate 12 electric wires 700 to pass through.
[0035] In order to further optimize the passing path of the electric wire 700, a first wire passing hole 140 is arranged on the inner side wall of the first connecting cylinder 110, which communicates the first connecting channel 131 and the first wire passing groove 120; similarly, a second wire passing hole 240 is arranged on the inner side wall of the second connecting cylinder, which communicates the second connecting channel 231 and the second wire passing groove 220. In this way, the electric wire 700 can pass more smoothly from the first wire passing groove 120 through the first wire passing hole 140 into the wire passing channel 310, and then through the second wire passing hole 240 into the second wire passing groove 220, avoiding the bending and extrusion of the electric wire 700 inside the hinge.
[0036] Referring to Figure 3 and Figure 4 In some embodiments, in order to meet the needs of different installation heights, the bottom of the shaft 300 is connected with a height adjusting nut 400. In particular, the height adjusting nut 400 is located in the first mounting channel 110, and is provided with a gap channel 410 coaxial with the wire passing channel 310 to ensure that the electric 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.
[0037] In order to cooperate with the use of the height adjusting nut 400, a through gap hole is arranged at the bottom of the first connecting cylinder 110, which communicates the first mounting channel 110. In this way, when the height needs to be adjusted, the user can conveniently operate the height adjusting nut 400 without worrying that it will interfere with the first connecting cylinder 110. Further, in order to keep the inside of the hinge clean and beautiful, a cover plate 150 is arranged on the first connecting cylinder 110 to close the gap hole. This cover plate 150 not only prevents dust and sundries from entering the inside of the hinge, but also protects the electric wire 700 from the interference of the external environment.
[0038] Referring to Figure 1In order to facilitate the installation and maintenance of the electric wire 700, the first fixing plate 100 and the second fixing plate 200 are provided with detachable sealing plates 600. The sealing plates 600 can be used to open or close the first wire passing groove 120 and the second wire passing groove 220, so that the user can conveniently access or replace the electric wire 700 when needed.
[0039] In order to improve the rotation stability and service life of the rotating shaft 300, a tensioning copper sleeve is sleeved on the rotating shaft 300. The copper sleeve is located in the second mounting channel 210 and tightly fits the inner side wall of the second mounting channel 210. The design of the tensioning copper sleeve not only reduces the friction between the rotating shaft 300 and the mounting channel, but also prevents the rotating shaft 300 from loosening or deviating during rotation.
[0040] Through the first connecting arm 130 and the second connecting arm 230, the height adjusting nut 400 and the tensioning copper sleeve, the structure of the fireproof overcurrent 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 passing groove 120, the second wire passing groove 220, the first connecting channel 131, the second connecting channel 231, the first wire passing hole 140 and the second wire passing hole 240, the electric wire 700 is completely hidden, the overall aesthetic degree of indoor decoration is improved, and the exposed electric wire 700 is prevented from becoming a fire spread guide, thereby improving the fireproof performance. The detachable sealing plate 600 and the height adjusting nut 400 make the installation and maintenance of the electric 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.
[0041] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the present application.
