Generally, the connecting frame can be integrally arranged with the top frame, and the connecting frame is detachably connected to a first guide rail 5, and one end of the first guide rail is provided with a first limiting protrusion 5-1 for limiting the rotation of the connecting frame. Among them, the first guide rail is preferably located on the side of the connecting frame facing the bottom frame. When the structure is in use, the first guide rail is fixed to a position near the top on the inner wall of the cylinder of the small capsule-shaped pressure-resistant cabin, the mounting frame is extended to the bottom along the cylinder wall, and then the top frame is placed on the first guide rail and rotated until the connecting frame is against the first limiting protrusion, and then the connecting frame and the first guide rail are connected. The advantages of this structure are: the guide rail is arranged corresponding to the top surface of the frame, and almost does not occupy the design space of the internal device, which is conducive to the miniaturization design of the small capsule-shaped pressure cabin; in addition, the guide rail arranged on the cylinder wall perpendicular to the axial direction of the cylinder is relatively shorter than the guide rail arranged parallel to the axial direction of the cylinder, especially by rotating it for subsequent installation, the length of the guide rail can be set shorter, and the guide rail is located at the top of the cylinder (also called a sleeve), so the processing difficulty when welding the guide rail is relatively small.

[0019] As a preferred embodiment, the connecting frame includes a first connecting frame 4-1 and a second connecting frame 4-2, and the first connecting frame and the second connecting frame are symmetrically arranged on the top frame; the first guide rail is detachably connected to the first connecting frame, and the first limiting protrusion is used to limit the rotation of the first connecting frame; the second connecting frame is detachably connected to the second guide rail 6, and by setting the second guide rail, the installation frame is fixed more firmly when the installation frame is fixed.

[0020] As a preferred embodiment, the mounting frame further includes a first baffle 7 and a second baffle 8. Generally, the first baffle and the second baffle are arc-shaped to match the shape of the cylinder. The first baffle is fixed to the inner wall of the cylinder of the small capsule-shaped pressure-resistant cabin during installation, and is arranged corresponding to the first guide rail, so as to limit the translation of the first connecting frame on the side of the first guide rail facing the first connecting frame when the first connecting frame rotates to abut against the first limiting protrusion; The second baffle is fixed on the inner wall of the cylinder of the small capsule-shaped pressure-resistant cabin during installation, and is arranged corresponding to the second guide rail, and is used to limit the translation of the first connecting frame on the side of the first guide rail facing the first connecting frame when the first connecting frame rotates to abut against the first limiting protrusion; the first guide rail is located on the side of the first connecting frame facing the bottom frame; the second guide rail is located on the side of the first connecting frame facing the bottom frame; in actual use, it is preferred to install a third guide rail 9 and a support block 10, and the third guide rail is fixed on the inner wall of the cylinder of the small capsule-shaped pressure-resistant cabin during installation, and is arranged corresponding to the position between the first guide rail and the second guide rail; the inner and outer sides of the support block are arc-shaped; the support block is fixed on the inner wall of the cylinder of the small capsule-shaped pressure-resistant cabin during installation, and is arranged close to the bottom, and is used to support the bottom frame when the first connecting frame rotates to abut against the first limiting protrusion. The installation method of this structure is as follows: 1. Avoid the first baffle 7 and the second baffle 8, and extend the installation frame to the bottom along the cylinder wall; Lay the upper top frame on top of the frame over the third rail; 2. Rotate the installation frame counterclockwise so that the first connecting frame of the installation frame cuts in between the first baffle and the first guide rail, and the second connecting frame cuts in between the second baffle and the second guide rail; 3. Rotate the frame until the first connecting frame contacts the first limiting protrusion; 4. Connect and fix the first connecting frame and the first guide rail, and connect and fix the second connecting member and the second guide rail; wherein, one or more fixing holes can be set on the first connecting frame and the second connecting frame, and corresponding fixing holes can be set on the first guide rail and the second guide rail. D-shaped buckles can be used for fixing to prevent the first connecting frame and the second connecting frame from rotating relative to the first guide rail and the second guide rail.

[0021] This structure has the following advantages: 1. Ability to quickly locate: Use guide rails and baffles to quickly locate the track position; 2. Quick installation: After entering the guide rail, rotate clockwise to reach the limit position, align the fixing holes with the corresponding fixing holes, and install two D-shaped buckles; 3. Maximize the utilization of cylindrical space: Except for the pillars, all other spaces of this frame can be fully utilized. For example, a circular PCB circuit board with an outer diameter slightly smaller than the inner diameter of the cylinder is installed (the pillars pass through the circular PCB board, and the two PCB boards are connected by bus sockets and stacked layer by layer) to maximize the utilization of space.

[0022] 4. Low cost: One side is disassembled and the other end is welded, which reduces the manufacturing and maintenance costs.

Generally, threads can be set on the pillars, and mounting holes are set on the four corners of the corresponding first closed bracket and the second closed bracket. The first closed bracket and the second closed bracket are fixed to the pillars by bolts to facilitate disassembly and assembly; the length of the first guide rail is greater than the length of the first arc-shaped plate, wherein the top frame can also be laser cut and formed in one piece, and the bottom frame can also be laser cut and formed in one piece. In this embodiment, it is preferred that the first guide rail, the second guide rail and the third guide rail are designed as follows: First guide rail: Any point at the top opening of the pressure cabin is 0°, and the first guide rail is an arc of 252.5° to 357.5° along the inner wall of the cylinder; Second guide rail: along the 97.5°~177.5° arc of the inner wall of the cylinder at the top opening of the pressure cabin; The third guide rail: an arc of 30° to 60° along the inner wall of the cylinder at the top opening of the pressure cabin; A third guide rail is arranged between the first guide rail and the second guide rail, and the three guide rails are in the same horizontal plane; Baffles (first baffle and second baffle) are respectively arranged at corresponding positions above the first guide rail and the second guide rail. The two mounting rings on the top of the mounting frame are in the same horizontal plane. After rotating to the limit point, they are just stuck between the guide rail and the baffle. At the same time, a support block is arranged at the bottom of the cylinder to play a supporting role after positioning.
