The water-proof elastic plug has the disadvantages that once condensed water or condensation occurs in the elastic plug part and the metal wrapping part, the water drainage difficulty is high, and indoor water seepage is easily caused.

Disclosure of Invention

The utility model relates to an overcome prior art's end cap and only can realize the function of one-way water shutoff, be difficult to solve the problem of discharge comdenstion water or condensation water, provide a two-way formula metal end cap, realize positive water shutoff, the hydrophobic two-way function of reverse side.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a two-way formula metal end cap, includes mount and movable plate, the top of movable plate is rotated and is connected on the mount, be equipped with the spillway hole on the mount, the movable plate covers the spillway hole, the movable plate is through rotating to change the spillway hole and open and close the state.

The utility model discloses a characteristics lie in improving on the basis of current roofing end cap, through seting up the spillway hole on the mount to add the movable plate in the spillway hole outside and seal as the shrouding, the movable plate covers the spillway hole under the dead weight effect under normal conditions, makes the spillway hole be in the normal close state and makes the water in the end cap outside can't flow backward, and the inboard ponding of end cap outwards opens the movable plate through pressure, through the ponding of spillway hole discharge. The purposes of positive water plugging and reverse water drainage are realized, and indoor water seepage is avoided.

Preferably, the top of the movable sheet is provided with a limiting plate extending in the direction away from the overflow hole.

The limiting plate rotates along with the movable piece, and when the movable piece rotated to certain angle, limiting plate and mount contact, the movable piece stall was restricted the movable piece turned angle, avoided the too big unable fall back of movable piece turned angle, and the limiting plate can also play the effect that keeps off the rain under the encapsulated situation simultaneously.

Preferably, the fixing frame comprises a web, an upper flange connected to the top end of the web, and a lower flange connected to the bottom end of the web, and the overflow holes are formed in the web.

The upper flange is used for connecting the ridge tile, and the lower flange is used for connecting the roof panel.

Preferably, the movable sheet is rotatably connected with the fixed frame through a pin shaft.

The pin shaft is made of galvanized round steel with the diameter of 1-2 mm.

Preferably, a torsion spring is arranged outside the pin shaft, and two ends of the torsion spring are respectively connected with the fixed frame and the movable sheet.

The movable sheet is pressed on the overflow hole through the pretightening force of the torsion spring to prevent backflow, and the movable sheet can also quickly return to close the overflow hole after being opened.

Preferably, the fixing frame is a galvanized plate member with the thickness of 1-3 mm.

Preferably, the movable sheet is a galvanized sheet member with the thickness of 0.6-1.2 mm.

Ensuring the strength and strong corrosion resistance.

Therefore, the utility model discloses following beneficial effect has: (1) the water overflow hole is formed in the web plate of the fixed frame, and the movable sheet is additionally arranged to be used as a sealing plate for sealing, so that water on the outer side of the plug cannot flow backwards, and accumulated water on the inner side of the plug can be discharged; (2) water accumulation on the roof and indoor water seepage are prevented; (3) the corrosion resistance is strong; (4) simple structure and convenient installation.
