[0033] like Figure 1-7As shown, a mobile house door that is easy to disassemble includes a door frame 1, a door panel 2 installed inside the door frame 1, and a fixing mechanism provided on the upper and lower sides of the door frame 1. The fixing mechanism includes two mounting grooves 3 symmetrically opened on the rear side wall of the door frame 1 and located at the top and bottom of the door frame 1, respectively; a fixing cylinder 4 symmetrically installed on both sides of the mounting groove 3 and having a cavity inside; a locking rod 5 inserted into the fixing cylinder 4 and slidably connected to the door frame 1; a locking block 6 provided at one end of the locking rod 5 near the middle of the door frame 1; a spring 7 provided on the outer wall of the locking rod 5 and used to connect the fixing cylinder 4 and the locking block 6; and a threaded rod 9 threadedly connected to the middle of the door frame 1 and having a locking plate 8 adapted to the locking block 6 at its bottom end. By setting the fixing mechanism on the door frame 1, the door frame 1 and the mobile house door can be connected to each other. The installation and fixing of the mobile house is simple and easy to disassemble, replacing the damage to the door frame 1 caused by traditional rivet and screw installation methods. The locking block 6 has an inclined guide surface 10 on the side near the locking plate 8. The guide surface 10 is located on the side of the locking block 6 near the door plate 2, and the side of the locking block 6 away from the door plate 2 has a limit slot 11. When the threaded rod 9 is turned to move the locking plate 8 towards the side near the locking block 6, the locking plate 8 slides along the guide surface 10 of the locking block 6 and squeezes the locking block 6 towards the side away from the locking plate 8 until the locking plate 8 is locked into the limit slot 11 of the locking block 6. At this time, the locking rod 5 is inserted into the interior of the mobile house, realizing the installation and fixing of the door frame 1. The inner side wall of the locking block 6 is connected to the slider 13 through the connecting rod 12. The door frame 1 has an internal groove 14 that matches the slider 13. When the locking block 6 moves, it drives the slider 13 to slide along the groove 14, ensuring the stability of the locking block 6 and the locking rod 5. The locking block 6 has an insertion hole 15 at one end near the limiting slot 11. The bottom of the door frame 1, located in the middle of the groove 14, has a limiting hole 16 that matches the insertion hole 15. When disassembling the door frame 1, the locking block 6 is pushed away from the locking plate 8. When the locking block 6 moves to the middle of the groove 14, the insertion hole 15 corresponds to the limiting hole 16, thus releasing the locking plate 8 from fixing the locking block 6. Another rod is then inserted into the limiting hole 16 along the insertion hole 15 to fix the locking block 6, making it easier to move the locking plate 8 between the two locking blocks 6. The sliding groove 14 is cross-shaped, and the slider 13 is also cross-shaped, which improves the stability of the slider 13's movement and prevents it from slipping out of the sliding groove 14. A protective cover 17 is provided at the bottom of the door panel 2 inside the door frame 1. The protective cover 17 is located at the bottom of the door panel 2, and each of the four corners of the protective cover 17 is provided with a plug 18. The inside of the door frame 1 has a slot that matches the plug 18. The plug 18 is magnetically connected to the door frame 1 through a magnetic piece. When the protective cover 17 is placed on the door frame 1, the plug 18 is inserted into the slot, covering the top of the threaded rod 9, which can prevent the threaded rod 9 from tripping the residents entering and exiting the mobile house.This also prevents the threaded rod 9 from wobbling and affecting the stability of the locking plate 8 in limiting the locking block 6. A groove 19 is provided in the middle of the rear side wall of the door panel 2. When the door panel 2 is closed inside the door frame 1, the threaded rod 9 above the door frame 1 is located inside the groove 19, preventing the threaded rod 9 at the top of the door frame 1 from affecting the closing of the door panel 2.

[0034] The working principle and usage process of this utility model are as follows: In use, the door frame 1 is embedded into the installation area of ​​the mobile home. A mounting hole corresponding to the locking rod 5 is made at the corresponding position in the installation area. First, the door panel 2 is opened. When the threaded rod 9 is turned, the locking plate 8 moves towards the side closer to the locking block 6. The locking plate 8 slides along the guide surface 10 of the locking block 6, pressing the locking block 6 away from the locking plate 8. The locking block 6 slides against the locking rod 5 along the fixing cylinder 4 and the door frame 1, pressing the spring 7 until the locking plate 8 is engaged in the limiting slot 11 of the locking block 6. At this point, the locking rod 5 is inserted into the installation hole of the mobile home, achieving the installation and fixation of the door frame 1. Then, the protective cover 17 is placed on the door frame 1, and the locking rod is inserted... Inserting 18 into the slot covers the top of the threaded rod 9, preventing the threaded rod 9 from tripping residents entering and exiting the mobile house. It also prevents the threaded rod 9 from shaking and affecting the stability of the locking plate 8 in limiting the locking block 6. When disassembling the door frame 1, push the locking block 6 away from the locking plate 8. When the locking block 6 moves to the middle of the slide groove 14, the insertion hole 15 corresponds to the limiting hole 16. At this time, the locking plate 8 is released from fixing the locking block 6. Take another rod and insert it into the limiting hole 16 along the insertion hole 15 to fix the locking block 6. This makes it easy to move the locking plate 8 out from between the two locking blocks 6. Under the elastic action of the spring 7, it is easy for the locking block 6 and the locking rod 5 to reset, thus realizing the disassembly of the door frame 1.
