detailed description

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.

As shown in FIG. 1 to FIG. 3, the cover of the embodiment includes a cover body 10 and a sealing member 20. The cover body 10 is provided with a wire outlet opening 11, and the sealing member 20 blocks the outlet port 11, and the sealing member 20 is provided with The threading hole 21 to which the outer diameter of the wire is to be fitted is to be threaded.

Applying the cover of the embodiment, the sealing member 20 blocks the outlet opening 11. The outer diameter of the thread to be threaded is matched with the aperture of the threading hole 21, and the opening area of the outlet opening 11 is greatly reduced, which effectively improves the opening. The sealing effect of the cover. Further, when the inside of the cover is ignited, the sealing member 20 better prevents the flame from being thrown out from the outlet port 11, so that the cover prevents the extension of the fire. The cover structure of the invention is simple, and the fire hazard at the outlet opening 11 of the cover is effectively avoided.

In the present embodiment, the cover body 10 has a projection portion 12, and an outlet passage communicating with the outlet port 11 is formed in the projection portion 12, and the sealing member 20 is disposed in the outlet passage. The outlet passage extends beyond the side wall 32 of the compressor 30. In the present embodiment, the cover 10 has an opening surface facing the compressor 30, and the cover further includes a gasket between the cover 10 and the compressor 30 and the outer edge of the gasket is larger than the outer edge of the opening surface. The shape of the bottom of the outlet passage is the same as that of the end cover and the gasket, which ensures a better sealing between the gasket and the cover.

In the present embodiment, as shown in FIGS. 4 to 6, the cover cooperates with the compressor 30, and the compressor 30 includes an end cover 31, a side wall 32, and a circular arc portion connecting the end cover 31 and the side wall 32, and the sealing member The position of 20 corresponds to the end cap 31. The sealing member 20 cooperates with the end cover, and the cover forms a sealed space with the compressor 30 to better ensure the sealing between the compressor 30 and the cover, and the sealing effect is better.
