However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-5 This is an embodiment of the present invention, which provides an emergency door with a quickly detachable door panel, comprising: The support assembly 100 includes a base 101, a column 102 fixedly connected to the side wall of the base 101, a crossbeam 103 fixedly connected to the end of the column 102, and a slider 104 slidably connected to the side wall of the column 102. The column 102 is symmetrically arranged at the end of the crossbeam 103. The door assembly 200 includes a frame 201 rotatably connected to the end of the central shaft of the sliding member 104, a plate 202 inserted into the center of the frame 201, a plug 203 inserted into the inner wall of the frame 201, and a spring 204 fixedly connected to the inner wall of the frame 201. The end of the spring 204 is fixedly connected to the inner wall of the plug 203. The end of the plug 203 is provided with a beveled structure that cooperates with the side wall of the plate 202. The end of the plug 203 is inserted into the middle of the slot in the side wall of the plate 202.

[0019] The base 101 provides ground support for the overall structure. Symmetrically arranged columns 102 and crossbeams 103 form the main frame of the portal frame. The columns 102 are fixed to the side walls of the base 101, and the crossbeams 103 connect the ends of the two columns 102, forming the top load-bearing structure. Sliding members 104 are symmetrically assembled on both side walls of the frame 201 and slidably connected to the side walls of the columns 102, enabling smooth lifting or sliding adjustment of the portal frame. The frame 201 serves as the mounting carrier for the portal panel, rotating with the sliding members 104 via a central shaft. This ensures that the portal frame can be adjusted in position with the sliding members 104 and that regular opening / closing actions can be achieved through rotation. The panel 202, as the core portal panel, is inserted into the center of the frame 201 using a plug-in method, providing a structural basis for subsequent quick disassembly. The insert block 203 mounted on the inner wall of the frame 201 and the spring 204 form an elastic snap-fit ​​unit. The spring 204 is sleeved on the outside of the pull rod 205, with one end fixed to the inner wall of the frame 201 and the other end fixedly connected to the insert block 203. The beveled structure at the end of the insert block 203 provides guidance for the installation of the plate 202: during installation, the plate 202 is inserted into the frame 201, squeezing the bevel, forcing the insert block 203 to compress the spring 204 and move inward; when the plate 202 reaches the preset position, the insert block 203 is reset under the action of the spring force and inserted into the slot on the side wall of the plate 202, completing the rapid fixation of the plate.

[0020] Specifically, the insert 203 is threadedly connected to a pull rod 205, a spring 204 is sleeved on the outside of the pull rod 205, the end of the pull rod 205 is inserted into the middle of the through hole in the side wall of the frame 201, and the end of the pull rod 205 is hinged to a handle that is rotatably set inside the groove in the side wall of the frame 201.

[0021] The pull rod 205, which is threaded through the center of the insert 203, passes through the through hole in the side wall of the frame 201. The handle, which is hinged at the end, is embedded in the groove in the side wall of the frame 201 (to avoid accidental contact). During disassembly, rotating the handle moves the pull rod 205 laterally, which, through threaded transmission, pulls the insert 203 to compress the spring 204, causing the insert 203 to disengage from the slot in the plate 202. At this point, the plate 202 can be directly pulled out, enabling quick disassembly of the door panel, which is suitable for rapid evacuation or equipment transfer needs in emergency scenarios.

[0022] Furthermore, the support assembly 100 also includes a support rod 105 fixedly connected to the side wall of the crossbeam 103, a driven wheel 106 rotatably connected to the end of the support rod 105, a pull rope 107 adapted to be installed in the middle of the driven wheel 106, and a main connector 108 fixedly connected to the end of the pull rope 107, the end of the main connector 108 being hinged to the side wall of the sliding member 104.

[0023] Among them, the end of the support rod 105 fixed to the side wall of the crossbeam 103 is rotatably connected to the driven wheel 106, the driving wheel 112 at the end of the crossbeam 103 forms a transmission cooperation with the driven wheel 106, the pull rope 107 is wound around the side wall of the two wheels, one end is wound on the driving wheel 112 and connected to the hook 113, and the other end is hinged to the side wall of the sliding member 104 through the main connecting member 108, which is used to drive the frame 201 to rise and fall synchronously and adjust the height of the plate 202.

[0024] Furthermore, the sliding member 104 is symmetrically arranged on the side wall of the frame 201. The end of the sliding member 104 on the lower side wall of the frame 201 is hinged to a secondary connector 109. The end of the secondary connector 109 is threadedly connected to a sleeve 110. The end of the sleeve 110 is threadedly connected to the end of the main connector 108.

[0025] Among them, the lower sliding member 104 of the frame 201 is threadedly connected to the sleeve 110 through the secondary connecting member 109, and the other end of the sleeve 110 is threadedly connected to the main connecting member 108, forming a linkage structure of the upper and lower sliding members, ensuring that the door moves synchronously up and down during the adjustment process and avoiding deviation; at the same time, the length of the threaded sleeve 110 can be finely adjusted to adapt to different installation accuracy requirements.

[0026] Preferably, a roller 111 is rotatably mounted on the side wall of the sliding member 104, and the roller 111 makes rolling contact with the inner wall groove of the column 102.

[0027] Among them, the sliding component 104 is symmetrically assembled on both sides of the frame 201 and slidably connected to the side wall of the column 102. The roller 111 rotatably installed on its side wall rolls with the inner wall groove of the column 102, converting sliding friction into rolling friction, greatly reducing the resistance when the door moves, and realizing the smooth lifting or sliding adjustment of the door.

[0028] It should be noted that a drive wheel 112 is rotatably mounted at the end of the crossbeam 103. The drive wheel 112 works in conjunction with the driven wheel 106. The end of the pull rope 107 is wound around the side wall of the drive wheel 112, and a hook 113 is fixedly connected to the end of the pull rope 107.

[0029] The support rod 105, fixed to the side wall of the crossbeam 103, is rotatably connected to the driven wheel 106. The driving wheel 112 at the end of the crossbeam 103 forms a transmission engagement with the driven wheel 106. The pull rope 107 is wound around the side walls of the two wheels, with one end wound around the driving wheel 112 and connected to the hook 113, and the other end hinged to the side wall of the sliding member 104 through the main connecting member 108, for synchronous driving. Preferably, the side wall of the crossbeam 103 is bolted to a support rod 114, and the end of the support rod 114 is bolted to the side wall of the base 101.

[0030] Among them, the crossbeam 103 and the base 101 are fixed by bolts to form a triangular support structure with a support rod 114, which improves the frame's resistance to deformation and stability, and is suitable for high-intensity use in emergency scenarios.

[0031] In use, the base 101 provides basic support by being fixed to the ground, and the column 102 and the beam 103 form a portal frame. Together with the support rod 114 between the beam 103 and the base 101, a triangular stable structure is formed, which greatly improves the frame's resistance to lateral forces and vertical loads, and ensures the structural stability in emergency situations. The sliding member 104 rolls with the inner wall groove of the column 102 via the roller 111, converting the sliding friction between the door and the frame into rolling friction and reducing adjustment resistance. The pull rope 107 is wound around the drive wheel 112 and the driven wheel 106. One end is connected to the upper sliding member 104 via the main connector 108, and the other end is connected to the lower sliding member 104 via the sleeve 110 and the auxiliary connector 109, forming a linkage structure between the upper and lower sliding members. When the hook 113 is pulled, the pull rope 107 is driven by the drive wheel 112, which synchronously drives the upper and lower sliding members 104 to rise and fall along the column 102, realizing rapid adjustment of the door height. The threaded connection design of the sleeve 110 can finely adjust the length of the upper and lower connectors, compensate for installation errors, and ensure synchronous adjustment.

[0032] When the plate 202 is inserted into the frame 201, its side wall presses against the beveled structure at the end of the insert 203, forcing the insert 203 to compress the spring 204 and move inward into the frame. Once the plate 202 is in place, the insert 203 resets under the elastic force of the spring 204 and inserts into the slot on the side wall of the plate 202, completing the automatic locking of the plate. Reliable fixation can be achieved without additional tools. In an emergency, the operator can rotate the handle on the side wall of the frame 201, and pull the insert 203 inward against the spring force through the pull rod 205, causing the insert 203 to disengage from the plate slot. At this time, the plate 202 can be directly pulled out. The entire process requires no tools. The door opens and closes normally through the rotational connection between the frame 201 and the sliding member 104. If height adjustment is required, pulling the hook 113 will drive the sliding member 104 to raise and lower the door to adapt to different passage needs. Rotate the handle to quickly disassemble panel 202, creating an unobstructed passage. If it is necessary to expand the passage space, the height of the door can be adjusted or its position can be moved by pulling the rope to meet the needs of emergency scenarios such as personnel evacuation and equipment transfer.

[0033] In summary, with the help of the inclined guide of the insert 203 and the elastic engagement of the spring 204, the panel installation can be automatically locked; through the mechanical transmission of the pull rod 205 and the handle, the disassembly process does not require tools and can quickly complete the separation of the door panel, meeting the high-intensity use in emergency scenarios; the roller design of the sliding part 104 and the synchronous transmission structure of the pull rope realize the smooth adjustment of the door height, and the fine adjustment function of the sleeve 110 can be adapted to different frame installations, thereby adapting to different sizes of panels (by adjusting the position of the frame and the insert), and the door height can be flexibly adjusted, making it suitable for a variety of scenarios.
