[0023] Please refer to Figures 1-3In the embodiment, the hinge includes a fixed frame 5, a first rotating block 6, a second rotating block 7, a first slot 8 and a second slot 9. The front end of the first mounting slot 4 is fixedly connected with the fixed frame 5. The right end inner wall of the fixed frame 5 is rotatably provided with the first rotating block 6. The right end of the first rotating block 6 is hingedly connected with the second rotating block 7. The upper and lower ends of the second rotating block 7 are penetrated through the first slot 8. The upper and lower ends of the second rotating block 7 are in contact with the upper and lower ends of the inner wall of the second mounting slot 11 through the hinge, so that the door frame 2 can be hingedly connected with the fixed plate 1. The inner wall of the second slot 9 is threadedly provided with a needle column 10.

The door frame 2 is made of a high-temperature-resistant metal material. The glass 3 is made of a high-temperature-resistant glass material. The overall fire resistance of the wardrobe door is improved, so as to ensure that the clothes in the wardrobe body are not burned.
[0024] Please refer to Figures 4-5 In the embodiment, the front end of the placing slot 12 is provided with a mounting plate 101. The mounting plate 101 is provided with a rotating stud 102. The rotating stud 102 is penetrated through the mounting plate 101 and is threadedly installed in the inner wall of the threaded slot 13. The mounting plate 101 is threadedly installed in the front end of the placing slot 12 through the rotating stud 102. The liquid storage box 103 is taken out and replaced after use. The front end of the liquid storage box 103 is in contact with the rear end of the mounting plate 101. The liquid storage box 103 is made of a thermoplastic plastic material. The connecting pipe 104 is made of a metal material. The liquid storage box 103 is affected by the temperature conduction of the door frame 2 and the mounting plate 101 itself. The liquid storage box 103 will soften at high temperature. In order to prevent the liquid storage box 103 from being blocked when it softens, the connecting pipe 104 is made of a metal structure, so that the lubricating oil in the liquid storage box 103 can effectively flow to the outer wall of the needle column 10. The two placing slots 12 are located above the second mounting slot 11. The lubricating oil in the two liquid storage boxes 103 on the placing slot 12 can flow downward under the influence of gravity under the heating condition, so as to protect and supplement the oil on the outer wall of the needle column 10.
[0025] During installation, the two needle columns 10 are sequentially penetrated through the hinge on the second mounting slot 11 above and below the second slot 9, and then the needle columns 10 are fixedly installed in the second slot 9 through a threaded manner.
[0026] When a fire occurs, the door frame 2 and the glass 3 can effectively isolate the flame. In order to prevent the needle column 10 from expanding at high temperature, the surface of the liquid storage box 103 will soften when the door frame 2 is heated. Then the spring 105 applies pressure to the pressing plate 108 downward, so that the pressing plate 108 extrudes the liquid storage box 103, so that the high-temperature-resistant lubricating oil in the liquid storage box 103 flows into the needle column 10 through the connecting pipe 104, and the high-temperature-resistant lubricating oil is supplemented.
[0027] When the liquid storage box 103 is used up, the mounting plate 101 is taken out from the front end of the placing groove 12 by selecting the rotating stud 102, so that the liquid storage box 103 in the placing groove 12 is taken out and replaced.
[0028] Through the above steps, when high temperature is received, the door frame 2 is heated to transfer heat to the liquid storage box 103, then the liquid storage box 103 is heated and softened, then the pressure of the upper end of the pressing plate 108 is pressed by the spring 105, the pressing plate 108 is pressed to the liquid storage box 103, so that the lubricant in the liquid storage box 103 is extruded from the connecting pipe 104 into the needle column 10 on the second groove body 9, so that the surface of the needle column 10 is lubricated, thereby preventing the needle column 10 from expanding and causing noise due to friction during subsequent use when high temperature is received.
[0029] The embodiments of the utility model are described in detail in combination with the drawings above, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
