The application discloses a bed type stainless steel heat accumulating high-temperature incinerator, wherein the lower chamber body is in a wind pipe structure, the upper chamber body is in a stainless steel corrugated concave-convex structure, the upper chamber body is located in the inner portion of the upper end of the lower chamber body and is communicated with the lower chamber body through a lower chamber body communication flat push valve.

This utility model belongs to the field of inflatable mattress technology, specifically relating to an inflatable mattress with a perforated reflective film. It includes an inflatable mattress body with an inflation cavity inside. Within the inflation cavity, there are reinforcing ribs and a perforated reflective film. The edges of the perforated reflective film are connected to the inner wall of the inflation cavity, and several perforations are provided on the perforated reflective film. Several reinforcing ribs are independent of each other; the upper end of each reinforcing rib is connected to the inner top wall of the inflation cavity, and the lower end of each reinforcing rib passes through the corresponding perforation and connects to the inner bottom wall of the inflation cavity. In this design, placing the perforated reflective film in the center of the inflation cavity can reflect the heat radiated by the human body, while reducing airflow within the inflation cavity and improving the thermal insulation performance of the inflatable mattress. Furthermore, since welding is not required between the reinforcing ribs or between the reinforcing ribs and the perforated reflective film, the amount of welding work is reduced, the number of welding points is decreased, and production efficiency is improved.

This invention discloses a method for heat-bending an outer T-shaped profile. The method includes: preparing and cutting the required web and top plates of the T-shaped profile; vertically welding and assembling the web and top plates on a continuous welding line; calculating the heating interval, heating time, and heating temperature according to set values; marking heating lines on the web and top plates, with each heating interval corresponding to one heating line on the web and one on the top plate, and the heating lines on the web and top plates forming a pair; fixing the T-shaped profile at both ends with L-shaped fixtures; and performing heat-bending according to the set heating lines, starting from one end of the T-shaped profile and proceeding along each pair of heating lines to the other end, following the order of web first, then top plate; measuring the angle at both ends of the heated T-shaped profile with an angle gauge; and calculating and adjusting the heat-bending process. This invention offers accurate positioning, high efficiency, and material savings.

The application relates to a construction method of a combined pipe body, which comprises the following steps: S1, obtaining a plurality of target pipe bodies, installing the target pipe bodies to preset positions, and obtaining a plurality of preset pipe body structures; a first connecting part is arranged on the inner wall of each target pipe body; S2, after the preset pipe body structures are obtained, a fixing assembly is installed between the outermost target pipe bodies in the adjacent two pipe body structures, and a combined pipe body is obtained; wherein the fixing assembly comprises an upper fixing part, a lower fixing part and a supporting column arranged between the upper fixing part and the lower fixing part; the supporting column is detachably connected to the upper connecting plate and the lower connecting plate through a first connecting part; and S3, a target component is connected to the first connecting part through a second connecting part. In the application, the detachable fixing assembly and the bolt connection mode can reduce the welding operation amount, the target component is installed after construction, the construction space in the pipe body during construction is improved, the construction efficiency is improved, and the construction difficulty in a narrow space is avoided.

This utility model discloses an IP54 protection rating lithium battery charger door panel structure, relating to the technical field of lithium battery charger door panels. The structure includes a charger door panel, an inner wall with a door lock, a cable routing groove fixedly connected to the inner wall of the door panel away from the door lock, a mounting component in the middle of the door panel, and a sealing component at the rear end. This utility model achieves reduced welding workload and improved work efficiency through folded edges and connecting components. The frame for mounting on the inner wall of the charger door panel uses a process of recessed folded edges on all four sides plus four connecting components for welding. While meeting waterproofing requirements, this greatly reduces the welding length, improves the aesthetic appearance of the door panel, and prevents deformation caused by prolonged heat exposure, while also reducing the workload of grinding the weld joints.
