Referring to fig. 2, a gasket 43 is embedded at the junction of the second hinge 41 and the lower case 8, the gasket having a circular/square structure, and the gasket 43 is provided with two sets. As shown in fig. 2, the upper part of the second hinge 41 is provided with a pressing plate 44, wherein one group of sealing gaskets is located at the bottom of the pressing plate 44, the other group of sealing gaskets is located at the top of the lower end face of the second hinge 41, that is, the pressing plate 44, the first group of sealing gaskets, the lower shell 8, the second group of sealing gaskets and the second hinge 41 are sequentially arranged at intervals, and finally a hexagonal bolt (G in fig. 2) is used to penetrate through the pressing plate 44 and the sealing gaskets 43 and is in threaded locking connection with the second hinge 41. In actual use, the tightness of the structure can be adjusted by adjusting the locking degree of the bolt.
The outer edge of the lower shell 8 is fixedly connected with a rib (H in fig. 2), and the front end of the rib is embedded with a sealing ring 9 (shown in fig. 1). The vertical section of the sealing ring 9 is shown in fig. 2, a U-shaped inner groove is formed in the upper portion of the sealing ring 9, a plurality of groups of extending portions are fixedly connected to the inner walls of the two sides of the inner groove, the vertical section of each extending portion is of a triangular structure, the extending portions incline downwards, and the inclination angle is 20-50 degrees (similar to a barb structure, and the purpose of the sealing ring is to increase friction force and pre-stress force on the basis of improving tightness). In actual installation, the sealing ring 9 is sleeved on the ribs, so that the ribs are inserted into the inner groove, and the extending part extrudes the ribs to prevent falling and deviation. In addition, the bottom fixed mounting at the sealing washer has connecting portion, and the vertical cross-section of connecting portion main part is oval structure, and the bottom both sides of connecting portion are all fixedly connected with extension, extension bilateral symmetry to the vertical cross-section of extension is triangle structure. In use, when the upper and lower shells 3, 8 are mutually capped, the connection on the sealing ring 9 is in direct contact with the upper shell 3 and pressed against each other. The connecting part and the expanding part are designed to prevent the sealing performance from being reduced due to deformation and deflection of the sealing ring during extrusion. This structure has at least three sealing points when pressed with the upper case 3, two expansion portions and the bottom surface of the connecting portion, respectively, so that even if there is deformation, normal sealing needs can be ensured.
The door lock component 1 is arranged on the inner side of the upper shell 3, a lock head structure matched with the door lock component 1 is arranged at a corresponding position of the lower shell 8, and the lock head and the door lock component 1 are the existing electric box door lock (such as a cabinet door lock with the model AB 509-1-2).
