[0002] The biphenyl heating box is a heating component used in a false-twist texturing machine. The synthetic fiber filaments deform upon contact with the heated rail surface within the heating box. Current biphenyl heating boxes typically consist of a box body, heated rails inside the box body, and a cover plate at the top opening of the box body. To reduce heat loss from the heated rail surface, rock wool is usually used to wrap the rails. However, existing biphenyl heating boxes suffer from the following problems in practical use: the seal between the cover plate and the opening of the box body is poor, easily causing heat loss from the inside of the box body, thus affecting performance. Therefore, a corresponding technical solution needs to be designed to address these issues. Summary of the Invention

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0014] The specific technical solution of this utility model is as follows:

[0015] like Figure 1 , Figure 2 and Figure 3As shown, an energy-saving biphenyl heating box includes a heating box body 1, a heating rail 2, rock wool filling material 3, and a cover plate 4. The heating box body 1 has an opening 5 at its top. The heating rail 2 and rock wool filling material 3 are disposed inside the heating box body 1. The cover plate 4 is disposed at the opening 5 for sealing or opening the opening 5. The top of the heating box body 1 has a positioning groove 6 located around the opening 5. The cover plate 4 is embedded in the positioning groove 6, and the bottom of the cover plate 4 has an annular sealing groove. The annular sealing groove has a sealing ring 7 that abuts against the bottom of the positioning groove 6. The bottom of the cover plate 4 has two protrusions 8 that extend into the interior of the heating box body 1. The opposing sides of the two protrusions 8 are respectively connected to locking blocks 10 through sliding grooves 9. The locking blocks 10 engage with the bottom wall at the opening 5, and the top of the locking blocks 10 has a first inclined surface 11. The bottom wall at position 5 has two mounting holes 12 corresponding to the locking blocks 10. A pressure block 14 is connected to the mounting hole 12 through a compression spring 13. The pressure block 14 abuts against the top of the locking block 10, and the bottom of the pressure block 14 has a second inclined surface 15 for cooperating with the first inclined surface 11. A lead screw 16 is rotatably mounted on the bottom of the cover plate 4 through a bracket. The two ends of the lead screw 16 pass through two protrusions 8 and extend into the slide groove 9. The two locking blocks 10 are threaded to the two ends of the lead screw 16 through threaded holes 17, and the threads of the two locking blocks 10 are opposite in direction. An operating rod 18 is rotatably mounted in the cover plate 4. The bottom end of the operating rod 18 extends into the interior of the hot box body 1 and is provided with a first bevel gear 19. A second bevel gear 20 is provided at the middle position of the lead screw 16 and meshes with the first bevel gear 19.

[0016] Furthermore, the top of the cover plate 4 is provided with an operation hole 21, and the top end of the operation rod 18 extends into the operation hole 21 and is provided with a rotating head 22.

[0017] Furthermore, the sealing ring 7 is a high-temperature resistant sealing ring.

[0018] Furthermore, the bottom and both sides of the hot rail 2 are respectively provided with insulation plates 23.

[0019] Furthermore, the insulation board 23 is a glass wool board.

[0020] In the use of this energy-saving biphenyl heating box, when it is necessary to seal the opening 5 of the heating box body 1: place the cover plate 4 in the positioning groove 6, and then use a tool to rotate the rotating head 22. The rotating head 22 drives the operating rod 18 and the first bevel gear 19 to rotate, and through the meshing of the first bevel gear 19 and the second bevel gear 20, drives the lead screw 16 to rotate, so that the lead screw 16 drives the two locking blocks 10 to move apart. The two locking blocks 10 will move out of the sliding groove 9 and engage with the bottom wall at the opening 5. During the movement of the locking blocks 10, the locking blocks 10 will drive the pressure block 14 to move into the mounting hole 12 and compress the compression spring through the contact and cooperation of the first inclined surface 11 and the second inclined surface 15. 13. At this time, the pressure block 14 can apply force to the locking block 10 and the cover plate 4 through the elastic force of the compression spring 13, so that the cover plate 4 keeps the sealing ring 7 pressed, thereby avoiding the occurrence of poor sealing, effectively improving the sealing between the cover plate 4 and the opening 5 of the hot box body 1, preventing the loss of heat inside the hot box body 1, and thus improving the use effect of the biphenyl hot box; when it is necessary to open the opening 5 of the hot box body 1: use a tool to rotate the rotating head 22 in the opposite direction. At this time, the two locking blocks 10 will move towards each other and move into the slide groove 9 respectively, thereby releasing the locking block 10 from the bottom wall of the opening 5. Then the cover plate 4 can be removed by the handle 24, thereby opening the opening 5 of the hot box body 1.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
