Technical Field

[0001] The utility model relates to the technical field of explosion-proof facilities, in particular to an explosion-proof window structure. Background Art

[0002] Currently, there are two types of transparent window materials: glass and PC. Due to the existing processing technology of the two materials, it is difficult to achieve the precision requirements for the outer circle size, so most of them use flat joint surfaces, which will result in a large window structure and difficult to use on small-sized products; the structure is too large, unsightly and uncoordinated; the cost is relatively high; and a small part is directly potted with the shell. Due to the large size of the shell, the operation is inconvenient, and after potting, it cannot be disassembled. If damaged, maintenance is difficult and the maintenance cost is high.

DETAILED DESCRIPTION

[0019] The following will be combined with the Figure 1-Figure 5 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly explained. Although the embodiments described are complete, it is obvious that the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
