[0003] The existing isolator cavity is large in volume, and the opening of the cavity surface door frame is large and the rigidity is insufficient, and the flatness deformation is large after welding. This kind of structure needs to weld the return air wall again during the general assembly installation, resulting in a large amount of heat deformation of the cavity. In addition, there are sanitary dead corners at the return air wall structure of the isolator. Content of the Utility Model
[0004] The purpose of the utility model is to provide a reinforcing structure and a cavity structure for an isolator, which solves the problem of large flatness deformation of the existing cavity structure.

A reinforcing structure for an isolator is welded to the window of the isolator and includes a bent rectangular part, a connecting part and a bending part. The two sides of the rectangular part are connected to the bending part through the connecting part. An opening for ventilation is formed between the top of the rectangular part and the isolator. The bending part is welded to both sides of the window.
[0006] A glass or an operating glove is installed on the reinforcing structure welded to the window of the isolator. In the prior art, in order to ensure ventilation, a return air wall is welded inside the door frame of the window of the isolator, and there are sanitary dead corners in the return air wall. Moreover, the existing door frame is welded to the window of the isolator on all four sides, and it is easy to deform during the welding process. In the utility model, the reinforcing structure includes a bent rectangular part, a connecting part and a bending part. Then, the bent reinforcing structure is welded to the window, reducing the number of welds and the deformation of the reinforcing structure. Moreover, the two sides of the rectangular part in the reinforcing structure are connected to the bending part through the connecting part, and an opening for ventilation is formed between the top of the rectangular part and the isolator. The return air plate does not need to be welded to the window again, reducing the amount of deformation and eliminating the sanitary dead corners.

Moreover, after the strengthening structure is welded to the window, the thickness on both sides of the window is further increased, playing a certain strengthening role for the isolator window. The strengthening structure can be welded to the window in one operation, reducing the deformation of the cavity, being simple in production, fast in assembly operation, and effectively avoiding the problem of sanitary dead corners existing in the previous structure.
[0009] A further technical solution of the present utility model is that: a connecting plate for welding to the top of the window is provided between the bending parts.
[0010] The connecting plate is placed between the bending parts and welded to the top of the window, avoiding the formation of sanitary dead corners here during ventilation. Moreover, the connecting plate is welded to the top of the window, increasing the thickness at the window, further improving the strength of the isolator and reducing deformation.

[0014] The gas inside the isolator can enter the strengthening structure through the ventilation cavity and then be discharged from the opening at the top of the strengthening structure.
[0015] The present utility model also provides an isolator cavity structure, including a frame for enclosing the cavity, and a plurality of windows are provided on the frame, and the above-mentioned strengthening structure is welded outside the windows.
[0016] Welding the strengthening structure to the outside of the window can increase the thickness of the window and the stability of the cavity.
[0017] A further technical solution of the present utility model is that: a wire threading channel is formed between the strengthening structures.
[0018] The strengthening structure is welded to the outside of the window. A wire threading channel will be formed between the strengthening structure and the frame. Together with the outer decorative panel on the outside of the strengthening structure, the wires or air pipes can be hidden inside. The air pipes and wires can be hidden inside the wire threading channel, which is both beautiful and can increase the strength of the cavity, avoiding the risk of the wiring being cut through the notch of the reinforcing rib.

Moreover, the two sides of the rectangular part in the strengthening structure are connected to the bending part through the connecting part, and a ventilation opening is formed between the top of the rectangular part and the isolator. The return air plate does not need to be welded to the window again, reducing the amount of deformation and eliminating the sanitary dead corners.
[0020] The design of the strengthening structure not only has the original function of the door frame, but also can form a ventilation channel, simplifies the cavity structure design, solves quality problems and effectively improves the assembly efficiency, saving assembly man-hours.
[0021] The strengthening structure includes a rectangular part, a connecting part and a bending part. The two sides of the rectangular frame are connected to the bending part through the connecting part, forming a structure with a U-shaped cross-section on both sides of the strengthening structure, which has higher strength than the plate-like structure and is not easy to deform. Moreover, after the strengthening structure is welded to the window, the thickness on both sides of the window is further increased, playing a certain strengthening role for the window of the isolator. The strengthening structure can be welded to the window once, reducing the deformation of the cavity, with simple production, fast assembly operation, and effectively avoiding the sanitary dead corner problem existing in the previous structure.
